02.43 | Support of Localised Service Area (SoLSA); Service description; Stage 1 | TS | 8.0.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.43/0243-800.zip | This technical specification, specifies a mechanism, which can be used as a platform for providing special tariffs and/or special set of service features for certain subscribers within a regionally restricted area or areas.
The motivation for this concept is to create means for network operators to build new service and tariff packages, which take into account subscriber groups and their needs.
The localised service area is both an optional network feature and an optional UE feature. Usage and implementation of the different SoLSA service features may vary according to operator's service packages.
This feature is not intended to replace the existing method of cell selection, cell indication and handover.
“Support of Localised service area (SoLSA)” is renamed Phase 2+ item “Support of Home Area Priority”
Note: The present document covers description for GERAN support only. UTRAN support will be added in latter releases. |
02.48 | Security mechanisms for the SIM Application Toolkit; Stage 1 | TS | 8.0.0 | C6 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.48/0248-800.zip | The present document provides standardised security mechanisms in conjunction with the SIM Application Toolkit for the interface between a GSM PLMN Entity and a SIM.
The security mechanisms which are specified are independent of applications.
The present document describes the functional requirements of the security mechanisms with the implementation detail of these mechanisms being described in the stage 2 specification (GSM 03.48).
The present document is the result of a feasibility study carried out on this topic, contained in GSM 11.15. |
02.53 | Tandem Free Operation (TFO); Service description; Stage 1 | TS | 8.0.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.53/0253-801.zip | The present document specifies the stage 1 description for the Tandem Free Operation (TFO) feature which provides the capability to avoid using two GSM speech codecs in mobile to mobile speech calls. The primary aim is to realise improvements in speech quality. The TFO mode of operation could also be used to reduce inter-Mobile services Switching Center (MSC) transmission bandwidth requirements.
In analogy with ITU-T Recommendations I.130 [1], Stage 1 is an overall service description, from the service subscriber's and user's standpoints, that views the network as a single entity which provides services to the user. |
02.56 | GSM Cordless Telephony System (CTS), Phase 1; Service description; Stage 1 | TS | 8.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.56/0256-801.zip | The scope of the present document is to describe the Service aspects of a GSM Cordless Telephony System (CTS), which provides the possibility for users of GSM terminals to have cordless access to a fixed network, such as PSTN/ISDN or a radio network such as GSM.
Due to the time constraints to have a first specification ready for market needs, a phased approach is necessary. The first phase aims primarily at an application supporting the speech teleservice (including DTMF support) in a residential single cell environment. The focus is on the requirements necessary to elaborate the radio interface and the security aspects for such an application.
To not prevent or impede the evolution of CTS to additional services and functions, later phases may have to be considered when now defining the means to fulfil the above mentioned requirements for the first phase of CTS. Therefore, additional support on the CTS radio interface for later phase services (e.g. SMS, subscriber authentication and GSM supplementary services), is included already in CTS Phase 1, provided that such services are clearly defined. Other expected services and functions in later phases are included in annex A.
The standardisation of the physical layers of the GSM-CTS fixed network interface is not in the scope of the present document. However, consideration may need to be given to communication of application data between CTS and PLMN via the fixed network. |
02.68 | Voice Group Call Service (VGCS); Stage 1 | TS | 8.2.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.68/0268-821.zip | The present document specifies the stage one description of the Voice Group Call Service (VGCS) which allows speech conversation of a predefined group of service subscribers in half duplex mode on the radio link taking into account multiple mobile service subscribers involved in the VGCS call per cell.
The VGCS is applicable to all mobile stations in a certain network and area which have the technical capability and the corresponding subscription, respectively, to participate in a VGCS call.
NOTE: It is not considered as requirement that normal GSM phase 2+ mobile stations will be able to be used for this service.
The service is described from the service subscriber's and user's point of view; in particular:
- the procedure for normal operation with successful outcome;
- the action to be taken in exceptional circumstances;
- the interaction with other GSM services and features.
The present document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the appropriate Global System for Mobile Communications (GSM) specifications.
The present document defines a teleservice of the digital cellular telecommunications system GSM. Any interaction with other services and/or networks not dealt with in clauses 7 or 8 are outside the scope of the present document. |
02.69 | Voice Broadcast Service (VBS); Stage 1 | TS | 8.2.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.69/0269-820.zip | The present document specifies the stage one description of the Voice Broadcast Service (VBS) which allows the distribution of speech (or other signals which can be transmitted via the speech codec), generated by a service subscriber, into a predefined geographical area to all or a group of service subscribers located in this area.
The Voice Broadcast Service (VBS) is applicable to all mobile stations in a certain network and area which have the technical capability and the respective subscription to receive a VBS call.
NOTE: It is not considered as requirement that normal GSM Phase 2+ mobile stations will be able to be used for this service.
The service is described from the service subscriber's and user's point of view; in particular:
- the procedure for normal operation with successful outcome;
- the action to be taken in exceptional circumstances;
- the interaction with other GSM services and features.
The present document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the appropriate Global System for Mobile communications (GSM) specifications.
The present document defines a teleservice of the digital cellular telecommunication system GSM. Any interaction with other services and/or networks not dealt within clauses 8 or 9 are outside the scope of the present document. |
02.76 | Noise Suppression for the AMR | TS | 8.0.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.76/0276-801.zip | The present document specifies the stage 1 description for the Noise Suppression feature for the AMR codec which enhances the input speech signal corrupted by acoustic noise. In analogy with CCITT Recommendations I.130†[1], Stage 1 is an overall service description, from the service subscriber’s and user’s standpoints, that views the network as a single entity which provides services to the user. |
02.95 | Support of Private Numbering Plan (SPNP); Service description; Stage 1 | TS | 8.0.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/02_series/02.95/0295-800.zip | The present document specifies the stage 1 description of Support of Private Numbering Plan (SPNP), which enables a subscriber to use a Private Numbering Plan (PNP) for communication across one or more networks with mobile and fixed users. The subscriber may belong to one or more (up to 9 maximum) Private Numbering Plans. The subscriber may also, subject to subscription, have access to the Public Numbering Plan. The structure and content of each PNP are defined by a PNP Manager, although these are out of the scope of the present document.
The service is described from the service subscriber's and user's points of view; in particular:
- the procedures for normal operation with successful outcome;
- the action to be taken in exceptional circumstances;
- the interaction with other GSM supplementary services.
The present document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the appropriate Global System for Mobile communications (GSM) specifications.
The charging principles applied to Support of Private Numbering Plan (SPNP) are outside of the scope of the present document.
Any interactions with other services and/or networks not dealt with in subclause 4.1 and clauses11 to 13 are outside the scope of the present document. |
03.05 | Technical performance objectives | TR | 8.0.0 | CP | https://www.3gpp.org/ftp/Specs/archive/03_series/03.05/0305-800.zip | The present document contains technical performance objectives that should be met for the fixed infrastructure of GSM PLMNs. Concerning transmission delay for the PLMN in clause 4, the requirements should also be met by GSM Mobile Stations (MS)s.
These performance design objectives are applicable to all implementations at all points in the growth cycle up to the maximum size. These reference loads and performance objectives may be used by manufacturers in designing GSM PLMNs and by Administrations or Recognised Private Operating Agencies (RPOA)s in evaluating a specific design or for comparing different designs for potential use in the Administration's or RPOA's intended implementation. |
03.10 | GSM Public Land Mobile Network (PLMN) Connection Types | TS | 8.3.0 | C3 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.10/0310-830.zip | A GSM PLMN may be described by a limited set of access interfaces (refer to 3GPP TS 04.02 and 02.01) and a limited set of GSM PLMN connection types to support the telecommunication services described in the 3GPP 02-series of specifications. This Global System for Mobile communications Technical Specification (TS) identifies and defines these connection types in so far as they relate to the particular network capabilities for a GSM PLMN.
The basic lower layer capabilities of a GSM PLMN are represented by a set of GSM PLMN connection types. The definition of a set of GSM PLMN connection types provides the necessary input to identify network capabilities of a GSM PLMN. In addition to describing network capabilities of a GSM PLMN, the identification of connection types facilitates the specification of network-to-network interfaces. It may also assist in the allocation of network performance parameters.
This specification should be considered in conjunction with other 3GPP specifications with particular reference to 3GPP TS 01.02, 02.01, 22.002, 02.03, 03.01, 23.002, 04.02 and 04.03.
This specification provides a bridge between the service specification in the 3GPP TS 02 and 22-series of specifications and the more detailed specifications such as the 3GPP TS 03, 04, 23, 24, 27 and 29 series. As such, it establishes a framework for the specification and understanding of the more detailed specifications. It is therefore not a specification against which detailed conformance testing can be performed. However, it shall be considered mandatory for the understanding of the more detailed specifications and used to resolve issues of conflict in these specifications.
From GSM R99 onwards the following services are no more required to be provided by a GSM PLMN:
• the dual Bearer Services “alternate speech/data” and “speech followed by data”
• the dedicated services for PAD and Packet access
• the single asynchronous and synchronous Bearer Services (BS 21..26, BS 31..34)
If a PLMN network still provides these services it has to fulfil the specification of GSM R98. |
03.13 | Discontinuous Reception (DRX) in the GSM System | TS | 8.0.0 | R6 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.13/0313-800.zip | The present document provides a system wide view of the operation of discontinuous reception on the GSM system.
The support of DRX is mandatory in GSM PLMNs.
The detailed coding and procedural details are defined in the relevant Technical Specifications dealing with the specific interfaces that are involved, for instance GSM 08.08 and GSM 04.08. Reference is also made to the framing on the air interface which is defined in Technical Specification GSM 05.02.
The present document gives an overview of the implementation of discontinuous reception DRX within the GSM system, the actions required at MSC, BSS, and MS, the support of the facility via the air interface, and some operational aspects of the facility. |
03.19 | Subscriber Identity Module Application Programming Interface (SIM API) for Java Card | TS | 8.5.0 | C6 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.19/0319-850.zip | The present document defines the stage two description of the Subscriber Identity Module Application Programming Interface (SIM API) internal to the SIM.
This stage two describes the functional capabilities and the information flow for the SIM API implemented on the Java Card 2.1 API specification [6].
The present document includes information applicable to network operators, service providers and SIM, server and database manufacturers. |
03.20 | Security-related network functions | TS | 8.6.0 | S3 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.20/0320-860.zip | This Technical Specification specifies the network functions needed to provide the security related service and functions specified in GSM 02.09.
This specification does not address the cryptological algorithms that are needed to provide different security related features. This topic is addressed in annex C. Wherever a cryptological algorithm or mechanism is needed, this is signalled with a reference to annex C. The references refers only to functionalities, and some algorithms may be identical or use common hardware. |
03.22 | Functions related to Mobile Station (MS) in idle mode and group receive mode | TS | 8.7.0 | R6 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.22/0322-870.zip | The present document gives an overview of the tasks undertaken by a GSM Mobile Station (MS) when in idle mode, that is, switched on but not having a dedicated channel allocated, e.g. not making or receiving a call, or when in group receive mode, that is, receiving a group call or broadcast call but not having a dedicated connection. It also describes the corresponding network functions. The idle mode functions are also performed by a GPRS MS as long as no dedicated channel is allocated to the MS. The idle mode functions are also performed by a CTS MS as long as the CTS MS is in manual mode GSM only or in automatic mode under PLMN coverage.
NOTE: The term GSM MS is used for any type of MS supporting one, or combinations, of the frequency bands specified in GSM 05.05.
The present document outlines how the requirements of the GSM 02 series Technical Specifications (especially GSM 02.11) on idle mode operation shall be implemented. Further details are given in GSM 04.08 and GSM 05.08.
Clause 2 of the present document gives a general description of the idle mode process. Clause 3 outlines the main requirements and technical solutions of those requirements. Clause 4 describes the processes used in idle mode. There is inevitably some overlap between these clauses. Clause 5 describes the cell change procedures for a MS in group receive mode.

1b Definitions and abbreviations
Abbreviations used in the present document are listed in GSM 01.04.
Selected PLMN This is the PLMN that has been selected according to subclause 3.1, either manually or automatically.
Available PLMN This is a PLMN where the MS has found a cell that satisfies conditions (ii) and (iv) of subclause 3.2.1.
Home PLMN (HPLMN) See 3GPP TS 23.122.
Registered PLMN (RPLMN) This is the PLMN on which certain LR outcomes have occurred (see 3GPP TS 23.122).
Equivalent PLMN A PLMN contained in the stored list of equivalent PLMNs. These PLMNs are considered equivalent to the selected PLMN regarding PLMN selection, cell selection, cell re-selection and handover (see 3GPP TS 23.122).
Registration This is the process of camping on a cell of the PLMN and doing any necessary LRs.
Camped on a cell The MS (ME if there is no SIM) has completed the cell selection/reselection process and has chosen a cell from which it plans to receive all available services. Note that the services may be limited, and that the PLMN may not be aware of the existence of the MS (ME) within the chosen cell.
Current serving cell This is the cell on which the MS is camped.
Suitable Cell This is a cell on which an MS may camp. It must satisfy criteria defined in subclause 3.2.1. For an MS in group receive mode, the suitable cell is determined by the criteria defined in subclause 5.2.3.
Acceptable Cell This is a cell that the MS may camp on to make emergency calls. It must satisfy criteria defined in sub clause 3.2.2.
Group call A communication in which several MSs can receive, but at most one may be allowed to transmit on a radio channel. Examples of group calls are those established for the voice group call service (VGCS, see GSM 03.68).
Broadcast call A communication in which several MSs can receive, but only the originator of the call is allowed to transmit on the radio channel. Examples of the broadcast call are those established for the voice broadcast service (VBS, see GSM 03.69).
Group receive mode State of the MS when it is engaged in a group or broadcast call as a listener.
GPRS MS An MS capable of GPRS services is a GPRS MS.
CTS MS An MS capable of CTS services is a CTS MS.
Location Registration (LR) An MS which is IMSI attached to non-GPRS services only performs location registration by the Location Updating procedure. A GPRS MS which is IMSI attached to GPRS services or to GPRS and non-GPRS services performs location registration by the Routing Area Update procedure only when in a network of network operation mode I. Both procedures are performed independently by the GPRS MS when it is IMSI attached to GPRS and non-GPRS services in a network of network operation mode II or III (see GSM 03.60).
Localised Service Area (LSA) A localised service area consists of a cell or a number of cells. The cells constituting a LSA may not necessarily provide contiguous coverage.
SoLSA exclusive access Cells on which normal camping is allowed only for MS with Localised Service Area (LSA) subscription.
Registration Area A registration area is an area in which mobile stations may roam without a need to perform location registration. The registration area corresponds to location area (LA) for performing location updating procedure and it corresponds to routing area for performing the routing area update procedure.
The PLMN to which a cell belongs (PLMN identity) is given in the system information transmitted on the BCCH (MCC + MNC part of LAI). |

03.33 | 3G Security; Lawful Interception; Stage 2 | TS | 8.1.0 | S3 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.33/0333-810.zip | The present document gives the stage 2 description of Lawful Interception within a PLMN for circuit switched systems and GPRS. It does not address the interface between the PLMN and the LEA lawful intercepted product and related information collection functions. This is outside the scope of the GSM standard.
The structure of the present document is as follows:
- clause 4 covers the architecture of the interception system;
- clause 5 describes how interception is activated, deactivated and interrogated within the interception system;
- clause 6 describes how the system is provisioned, defines events at which interception takes place and what kind of information is generated at each event;
- clause 7 provides brief descriptions of various intercept cases;
- clause 8 reviews security requirements for access to the interception system;
- annex A provides information flows to illustrate when intercepted traffic and related data is generated;
- annex B describes an interception system for GPRS. The annex is subdivided into 5 sections that are identical in structure to clauses 4 through 8, but applicable to a GPRS clause rather than a GSM circuit switched system. |
03.45 | Technical Realization of Facsimile Group 3 Service - transparent | TS | 8.0.1 | C3 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.45/0345-801.zip | The present document deals with the procedures allowing the technical realization of the Group 3 facsimile Service within the GSM PLMN using transparent Network support, according to the definition of Teleservice 61 and 62 specified in the GSM 02.03 [2]. |
03.46 | Technical Realization of Facsimile Group 3 Service - non transparent | TS | 8.0.1 | C3 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.46/0346-801.zip | The present document deals with the procedures allowing the technical realization of the real time end‑to‑end facsimile group 3 service within the GSM PLMN using non‑transparent network support according to the definition of the Teleservices 61 and 62 specified in GSM 02.03. Within the present document particular attention is given to Teleservice "Alternate speech/facsimile group 3" (Teleservice 61). However, the definitions apply also to Teleservice "Automatic facsimile group 3" (Teleservice 62) with the exception of all actions concerned with the speech phase. Consequently, in the following descriptions the term "Teleservice" denotes both Teleservice 61 and Teleservice 62 as appropriate.
NOTE: Some facilities associated with alternate speech/ facsimile group 3 may not be available with version 1 of MAP. In particular, the in‑call modification procedure following an inter MSC handover is not supported by this version. This imposes the limitation that for all calls it will not be possible to change between speech and facsimile following an inter MSC handover. |
03.48 | Security mechanisms for SIM application toolkit; Stage 2 | TS | 8.9.0 | C6 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.48/0348-890.zip | The present document specifies the structure of the Secured Packets in a general format and in implementations using Short Message Service Point to Point (SMS-PP) and Short Message Service Cell Broadcast (SMS-CB).
Furthermore, the coding is specified for a set of common application commands within the secured packets. This set is a subset of commands specified in TS 11.11 [5] and allows remote management of files on the Subscriber Identity Module (SIM) in conjunction with SMS and the SIM Data Download feature of TS 11.14 [6].
For SIM cards based on TS 03.19 [15], the set of commands used in the remote applet management is defined in the present document. This is based on the Open Platform card management specification [14]. For SIM cards based on other technologies, other loading mechanisms may be used.
The present document is applicable to the exchange of secured packets between an entity in a GSM PLMN and an entity in the SIM.
Secured Packets contain application messages to which certain mechanisms according to TS 02.48 [2] have been applied. Application messages are commands or data exchanged between an application resident in or behind the GSM PLMN and on the SIM. The Sending/Receiving Entity in the GSM PLMN and the SIM are responsible for applying the security mechanisms to the application messages and thus turning them into Secured Packets. |
03.50 | Transmission Planning Aspects of the Speech Service in the GSM Public Land Mobile Network (PLMN) System | TS | 8.1.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.50/0350-811.zip | The present document describes the transmission planning aspects pertaining to the speech service in the GSM PLMN system. Due to technical and economic factors, there cannot be full compliance with the general characteristics of international telephone connections and circuits recommended by the ITU‑T.
The present document gives guidance as to the precautions, measures and minimum requirements needed for successful interworking of the PLMN with the national and international PSTN. The present document identifies a number of routeing and network configurations. The objective is to reach a quality as close as possible to ITU‑T standards in order to safeguard the performance seen by PSTN customers. |
03.52 | Lower layers of the GSM Cordless Telephony System (CTS) radio interface; Stage 2 | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.52/0352-801.zip | The present document gives an overall description of the lower layers of the radio interface for GSM based Cordless Telephony Systems (GSM-CTS).
The GSM-CTS system is intended to provide a cordless connection between the fixed network and GSM-based CTS Mobile Stations (CTS-MS) via a private CTS Fixed Part (CTS-FP).
Stage 1 is an overall description, from the service subscribers and user's standpoint, that view the network as a single entity which provides service to the user. GSM 02.56 contains the CTS Stage 1 service description.
GSM 03.56 is a Stage 2 document that describes the system architecture of the GSM Cordless Telephone Systems (GSM-CTS), i.e. the system elements, the system interfaces and the functional capabilities. |
03.53 | Tandem Free Operation (TFO); Service description; Stage 2 | TS | 8.0.0 | S4 | https://www.3gpp.org/ftp/Specs/archive/03_series/03.53/0353-800.zip | The present document defines the stage 2 service description for Tandem Free Operation (TFO) in GSM. Tandem Free Operation applies only to speech calls.
Note: the TFO principles are built so that they could be used as well by other systems other than GSM.
In analogy with CCITT Recommendations I.130 [2] and with reference to CCITT Recommendations VI.1 Q.65 (Stage 2 of the method for the characterisation of services supported by an ISDN), the second stage of the following three-level structure is derived from a stage 1 service description.
Stage 1 is an overall service description, from the service subscriber's and user's standpoints, that views the network as a single entity which provides services to the user.
Stage 2 identifies the functional capabilities and information flows needed to support the service described in stage 1. Furthermore, it identifies various possible physical locations for the functional capabilities. The output of Stage 2, which is signalling system independent, is used as an input to Stage 3, the design of signalling system and switching Recommendations.
Stage 3 defines the signalling system protocols and switching functions needed to implement the service described in stage 2. |

Its main objective is to be a guidance for the interface between the 3GPP Technical Specifications in the 05‑series and the 04‑series. It also specifies the format of signalling channels and the order of bit transmission.
As far as possible, the present document makes use of the layering principles of the Reference Model for Open System Interconnection (OSI) as contained in ITU-T Recommendations X.200 and X.210. |
04.05 | Data Link (DL) Layer General Aspects | TS | 8.0.2 | R6 | https://www.3gpp.org/ftp/Specs/archive/04_series/04.05/0405-802.zip | The present document describes in general terms the Link Access Procedures on the Dm channel, LAPDm. The application of this protocol to other channel types is for further study. Details are provided in 3GPP TS 04.06.
The purpose of LAPDm is to convey information between layer 3 entities across the GSM PLMN radio interface (MS to network interface) using the Dm channel.
NOTE 1: The term Dm channel is used for convenience to designate the collection of all the various signalling channels required in the GSM system. See also 3GPP TS 04.03.
The definition of LAPDm is based on the principles and terminology of:
‑ CCITT Recommendations X.200 and X.210: the reference model for Open Systems Interconnection (OSI);
‑ CCITT Recommendations Q.920 and Q.921: the specification of LAPD for the user‑network interface in ISDN;
‑ CCITT Recommendation X.25 LAPB: user‑network interface for packet mode terminals; and
‑ ISO 3309 and ISO 4335: High‑level Data Link Control (HDLC) standards for frame structure and elements of procedures.
LAPDm is a protocol that operates at the data link layer of the OSI architecture. The relationship between the data link layer and other protocol layers is defined below.
NOTE 2: The interface between the mobile station and external terminal equipment/terminal adapters is defined in the Technical Specifications of the 3GPP TS 07‑series.
NOTE 3: The physical layer on the radio interface is defined in 3GPP TS 04.04 and layer 3 is defined in 3GPP TS 04.07, 04.08, 04.10 and 04.11. Reference should be made to these Technical Specifications for the complete definitions of the protocols and procedures across the GSM PLMN radio interface.
NOTE 4: The term "data link layer" is used in the main text of the present document. However, mainly in figures and tables, the terms "layer 2" and "L2" are used abbreviations. Furthermore, in accordance with 3GPP TS 04.07 and 04.08 the term "layer 3" is used to indicate the layer above the data link layer.
LAPDm is independent of the transmission bit rate. It requires physical channels with characteristics as defined in 3GPP TS 04.03.
Section 2 below describes basic concepts used in the present document and 3GPP TS 04.06.
Section 3 gives an overview description of LAPDm functions and procedures.
Section 4 summarizes the services that the data link layer provides to layer 3 and the services that the data link layer requires from the physical layer.

The detailed descriptions of the protocols and the related procedures are described in GSM 04.18, TS 23.108 and TS 24.008.
When the notations for "further study" or "FS" or "FFS" are present in this ETS they mean that the indicated text is not a normative portion of this standard.
These procedures are defined in terms of messages exchanged over the control channels of the radio interface. The control channels are described in GSM 04.03.

04.13 | Performance Requirements on Mobile Radio Interface | TS | 8.0.1 | C1 | https://www.3gpp.org/ftp/Specs/archive/04_series/04.13/0413-801.zip | The present document specifies measurable performance requirements for signalling aspects of Mobile Stations (MS)s. To allow implementation flexibility it has been chosen to specify requirements on the whole Mobile Station rather than to specify requirements on each "OSI layer". As a consequence the performance requirements do not fit conveniently in specifications such as GSM 04.08 [4] (layer 3 only) or GSM 04.06 [3] (layer 2 only).
The main aim of the present document is to provide the justification for testing of requirements that are not included in other GSM specifications. Where specific requirements are included in other GSM specifications they are not duplicated here.
MSs have to perform a wide variety of functions. As a consequence most performance measurements have to be made under a set of defined conditions: where necessary, these are included in the present document.
Where necessary certain assumptions are made about the interaction times between the mobile equipment and the SIM. If the (test) SIM does not respond within the assumed time then appropriate allowances shall be made.
Additionally, it is intended that the present document should contain sufficient requirements to enable some undefined network timers in GSM 04.08 [4] to be calculated. |

However, except for the Electrical Man Machine Interface (EMMI) and the Multi-slot TCH Loops, they are required for every mobile station.
For conformance tests, functions are activated via the radio interface, test SIM or dedicated pins. These functions must be capable of being activated when a test SIM is present but must not function with any other (e.g. network) SIM present except where otherwise stated within the present document. In this state, the MS must be able to perform all functions specified in the present document; in addition however, the special conformance testing functions must be operational.
The special conformance testing functions of the ME are enabled by use of a dedicated Subscriber Identity Module (test SIM, see 3GPP TS 11.10-1 Annex 4). SIM, in general, is described in 3GPP TS 11.11. The ME recognizes the test SIM by the Administrative Data Field.
The present document applies to the public land mobile radio service in the GSM900 and DCS1800 systems, using constant envelope modulation and operating on radio frequencies in the 900 and 1800 MHz bands respectively with a channel separation of 200 kHz and carrying 8 full rate channels or 16 half rate channels per carrier according to the TDMA principle.
The present document is part of the GSM-series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM related TS, nor is it created to provide full understanding of (or parts of) the GSM900 and DCS1800 systems.
The present document applies to the unit which includes the hardware to establish a connection across the radio interface. |

Use of logical control channels
The logical control channels are defined in 3GPP TS 05.02. Three similar sets of logical channels are defined. The first set consists of the logical channels:
- Broadcast Control Channel (BCCH): downlink only, used to broadcast Cell specific information;
- Paging Channel (PCH): downlink only, used to send page requests to Mobile Stations (MSs);
- Random Access Channel (RACH): uplink only, used to request GPRS resources or a Dedicated Control Channel;
- Access Grant Channel (AGCH): downlink only, used to allocate GPRS resources or a Dedicated Control Channel;
- The second set consists of the logical channels:
- Packet Broadcast Control Channel (PBCCH): downlink only, used to broadcast Cell specific information;
- Packet Paging Channel (PPCH): downlink only, used to send page requests to Mobile Stations (MSs);
- Packet Random Access Channel (PRACH): uplink only, used to request GPRS resources;
- Packet Access Grant Channel (PAGCH): downlink only, used to allocate GPRS resources;
- Packet Associated Control Channel (PACCH): bi-directional, associated with a Temporary Block Flow (TBF);
- Packet Timing advance control channel uplink (PTCCH/U): used to transmit random access bursts to allow estimation of the timing advance for one MS in transfer state;
• Packet Timing advance control channel downlink (PTCCH/D): used to transmit timing advance updates for several MS. One PTCCH/D is paired with several PTCCH/U's.
- The third set consists of the logical channels (COMPACT control channels):
- COMPACT Packet Broadcast Control Channel (CPBCCH): downlink only, used to broadcast Cell specific information; This channel is used to broadcast the same pieces of information as the PBCCH, but has a different physical structure (see 3GPP TS 05.02); In the remainder of this specification PBCCH shall be interpreted as PBCCH and CPBCCH unless specifically mentioned to be otherwise;
- COMPACT Packet Paging Channel (CPPCH): downlink only, used to send page requests to Mobile Stations (MSs) on a COMPACT control channel; In the remainder of this specification PPCH shall be interpreted as PPCH and CPPCH unless specifically mentioned to be otherwise;
- COMPACT Packet Random Access Channel (CPRACH): uplink only, used to request GPRS resources on a COMPACT control channel; In the remainder of this specification PRACH shall be interpreted as PRACH and CPRACH unless specifically mentioned to be otherwise;
- COMPACT Packet Access Grant Channel (CPAGCH): downlink only, used to allocate GPRS resources on a COMPACT control channel; In the remainder of this specification PAGCH shall be interpreted as PAGCH and CPAGCH unless specifically mentioned to be otherwise;

- Packet Timing advance control channel downlink (PTCCH/D): see above. |
04.64 | General Packet Radio Service (GPRS); Mobile Station - Serving GPRS Support Node (MS-SGSN) Logical Link Control (LLC) layer specification | TS | 8.7.0 | C1 | https://www.3gpp.org/ftp/Specs/archive/04_series/04.64/0464-870.zip | The present document defines the Logical Link Control (LLC) layer protocol to be used for packet data transfer between the Mobile Station (MS) and Serving GPRS Support Node (SGSN).
It defines the frame structure, elements of procedure, format of fields, and procedures for the proper operation of the logical link control layer. It is based on ideas contained in IS-130 [21], ISO 3309 [16], ISO 4335 [17], and ISO 7809 [18, 19, 20] (HDLC of ISO), as well ITU-T Q.920 [13] and Q.921 [14] (LAPD). The concepts, the overview description of LLC layer functions and procedures, and the relationship with other Technical Specifications are described in general terms in 3GPP TS 03.60 [5].
LLC spans from the Mobile Station (MS) to the Serving GPRS Support Node (SGSN). LLC is intended for use with both acknowledged and unacknowledged data transfer.
The frame formats defined for LLC are based on those defined for LAPD and RLP. However, there are important differences between LLC and other protocols, in particular with regard to frame delimitation methods and transparency mechanisms. These differences are necessary for independence from the radio path.
The LLC procedures are modelled upon the concepts of HDLC as outlined in ISO 4335. Data sequence integrity between the data source and data sink is effected by means of a cyclic numbering scheme. An independent numbering scheme is used for each logical data link, as identified by the a data link connection identifier. LLC supports two modes of operation:
- Unacknowledged peer-to-peer operation:
A logical link entity may initiate transmissions to a peer entity without prior establishment of a logical connection with the peer entity. LLC does not guarantee in-order delivery. LLC can detect errors in a received frame, and, depending on whether the frame is sent in protected mode or not, either discard or deliver the erroneous frame. No error recovery procedures are defined at the LLC layer. Higher-layer protocols can be used to provide reliability, if needed. This mode of operation is known as Asynchronous Disconnected Mode (ADM).
- Acknowledged peer-to-peer operation:
A balanced data link involves two participating entities, and each entity assumes responsibility for the organisation of its data flow and for error recovery procedures associated with the transmissions that it originates. Each entity operates as both a data source and data sink in a balanced link, allowing information to flow in both directions. This mode of operation is known as Asynchronous Balanced Mode (ABM), and provides a reliable service with in-order delivery.
The present document is organised as follows:
- An overview of the LLC layer functions is given in clause 4.
- The frame structure for peer-to-peer communication is given in clause 5.
- The elements of procedure and formats of fields are given in clause 6.
- The elements of layer-to-layer communication are contained in clause 7.
- The details of the peer-to-peer ABM procedures are given in clause 8.
- The details of LLC frame ciphering are given in annex A.
- The details of the TOM protocol layer are contained in annex B.

The user of the services provided by SNDCP is a packet data protocol (PDP) at the mobile Station (MS) or the Relay at the Serving GPRS Support Node (SGSN). Additionally, a control entity, e.g., AT command interpreter, may be an SNDCP user. SNDCP uses the services provided by the Logical Link Control (LLC) layer 4 and the Session Management (SM) sub-layer 2.
The main functions of SNDCP are:
- Multiplexing of several PDPs.
- Compression / decompression of user data.
- Compression / decompression of protocol control information.
- Segmentation of a network protocol data unit (N‑PDU) into Logical Link Control Protocol Data Units (LL‑PDUs) and re-assembly of LL‑PDUs into an N‑PDU.

Requirements are defined for two categories of parameters:
‑ those that are required to provide compatibility between the radio channels, connected either to separate or common antennas, that are used in the system. This category also includes parameters providing compatibility with existing systems in the same or adjacent frequency bands;
‑ those that define the transmission quality of the system.
This EN defines RF characteristics for the Mobile Station (MS) and Base Station System (BSS). The BSS will contain Base Transceiver Stations (BTS), which can be normal BTS, micro‑BTS or pico-BTS. The precise measurement methods are specified in 3GPP TS 11.10 and 3GPP TS 11.21.
Unless otherwise stated, the requirements defined in this EN apply to the full range of environmental conditions specified for the equipment (see annex D).
In the present document some relaxation's are introduced for GSM 400 MSs, GSM 900 MSs and GSM 850 MSs which pertain to power class 4 or 5 (see subclause 4.1.1). In the present document these Mobile Stations are referred to as "small MS".
MSs may operate on more than one of the frequency bands specified in clause 2. These MSs, defined in 3GPP TS 02.06, are referred to as "Multi band MSs" in this EN. Multi band MSs shall meet all requirements for each of the bands supported. The relaxation on GSM 400 MSs, GSM 900 MSs and GSM 850 MSs for a "small MS" are also valid for a multi band MS if it complies with the definition of a small MS.
The RF characteristics of repeaters are defined in annex E of this EN. Annexes D and E are the only clauses of this EN applicable to repeaters. Annex E does not apply to the MS or BSS.
This document also includes specification information for mixed mode operation at 850 MHz and 1900 MHz. (MXM 850 and MXM 1900). 850 MHz and 1900 MHz mixed-mode is defined as a network that deploys both 30 kHz RF carriers and 200 kHz RF carriers in geographic regions where the Federal Communications Commission (FCC) regulations are applied or adopted.
The requirements for a MS in a mixed-mode system, MXM 850 and MXM 1900, correspond to the requirements for GSM 850 MS and PCS 1900 MS respectively. |

The use of this transcoding scheme for other applications has not been considered.
In GSM 06.01, a reference configuration for the speech transmission chain of the digital cellular telecommunications system is shown. According to this reference configuration, the speech encoder takes its input as a 13 bit uniform PCM signal either from the audio part of the mobile station or on the network side, from the PSTN via an 8 bit/A‑ or -law (PCS 1900) to 13 bit uniform PCM conversion. The encoded speech at the output of the speech encoder is delivered to a channel encoder unit which is specified in GSM 05.03. In the receive direction, the inverse operations take place.
The present document describes the detailed mapping between input blocks of 160 speech samples in 13 bit uniform PCM format to encoded blocks of 260 bits and from encoded blocks of 260 bits to output blocks of 160 reconstructed speech samples. The sampling rate is 8000 sample/s leading to an average bit rate for the encoded bit stream of 13 kbit/s. The coding scheme is the so‑called Regular Pulse Excitation ‑ Long Term prediction ‑ Linear Predictive Coder, here‑after referred to as RPE‑LTP.
The present document also specifies the conversion between A‑ and -law (PCS 1900) PCM and 13 bit uniform PCM.

It is the intention of SMG11 to perform analysis and validation of any AMR noise suppression solution which is voluntarily brought to the attention of SMG11 in the future, using the requirements set out in this specification to facilitate such an analysis. In order for SMG11 to endorse such a solution, SMG11 must confirm that all the recommended minimum performance requirements are met. |
06.78 | Results of the AMR noise suppression selection phase | TR | 8.0.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/06_series/06.78/0678-801.zip | This technical report provides background information on the performance of the six candidates which were proposed as solutions for publication of an example noise suppression solution for application to the GSM Adaptive Multi-Rate (AMR) speech codec. Experimental test results from the speech quality related testing are reported to illustrate the behaviour of the candidate algorithms in multiple operational conditions. Additional information is also provided covering data not necessarily directly associated with speech quality (such as complexity, delay, effect on voice activity factor). |
06.81 | Discontinuous Transmission (DTX) for encanced full rate speech traffic channels | TS | 8.0.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/06_series/06.81/0681-801.zip | The present document gives a description of the general baseband operation of Enhanced Full Rate speech traffic channels in the transmitter and in the receiver of GSM Mobile Stations (MS)s and Base Station Systems (BSS)s during Discontinuous Transmission (DTX).
For clarity, the description is structured according to the block diagrams in figures 1 and 4. Except in the case described next, this structure of distributing the various functions between system entities is not mandatory for implementation, as long as the operation on the air interface and on the speech decoder output remains the same.
In the case of BSSs where the speech transcoder is located remotely in the Base Station Controller (BSC), the implementation of the interfaces between the DTX handlers and the Radio Sub System (RSS) as described in the present document together with all their flags is mandatory, being part of the A‑bis interface as described in GSM 08.60 [13].
The DTX functions described in the present document are mandatory for implementation in the GSM MSs. The receiver requirements are mandatory for implementation in all GSM BSSs, the transmitter requirements only for those where downlink DTX will be used. |
06.82 | Voice Activity Detection (VAD) for enhanced full rate speech traffic channels | TS | 8.0.1 | S4 | https://www.3gpp.org/ftp/Specs/archive/06_series/06.82/0682-801.zip | The present document specifies the Voice Activity Detector (VAD) to be used in the Discontinuous Transmission (DTX) as described in GSM 06.81 [5] Discontinuous transmission (DTX) for Enhanced Full Rate (EFR) speech traffic channels.
The requirements are mandatory on any VAD to be used either in GSM Mobile Stations (MS)s or Base Station Systems (BSS)s that utilize the enhanced full-rate speech traffic channel. |
06.85 | Subjective tests on the interoperability of the HR/FR/EFR speech codecs; single, tandem and tandem free operation | TR | 8.0.0 | S4 | https://www.3gpp.org/ftp/Specs/archive/06_series/06.85/0685-800.zip | The present document contains the results obtained from an internationally co-ordinated subjective evaluation conducted by four laboratories to estimate the performance in mobile-to-mobile connections of the GSM half, full, and enhanced full rate speech codecs (including the expected advantages of the Tandem Free Operation), in case of inter-operability in the digital cellular telecommunications system. These (listening-only) tests did not include the effects of Voice Activity Detector, Comfort Noise Insertion and the Discontinuous Transmission. |
08.01 | General Aspects on the BSS-MSC Interface | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.01/0801-801.zip | The present document is an introduction to the 3GPP TS 08.0x series of Technical Specifications and deals with the definition of the base station system (BSS) to mobile switching centre (MSC) (referred to as the A-interface) defined for the GSM system.
It also introduces Technical Specifications in the 3GPP TS 08.20 series, dealing with the support of data services on this interface.
The present document gives an overview of the content of the 3GPP TS 08.0x and 3GPP TS 08.20 series of Technical Specifications explaining how the detailed content of the Technical Specifications is partitioned and how the Technical Specifications can be used to support a full BSS-MSC interface. |
08.02 | Base Station System - Mobile Services Switching Centre (BSS-MSC) Interface - Interface Principles | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.02/0802-801.zip | The present document gives the principles on which the detailed interface specifications in the rest of the 3GPP TS 08.0X series of Technical Specifications are based.
The set of fixed equipment accessed from the MSC through one particular instance of the interface will be later referred to as a Base Station System (BSS). A BSS ensures the coverage of n cells, where n can be 1 or more.
The function of a BSS may be further subdivided into a control function, performed by one Base Station Controller (BSC) and a transceiving function, performed by "n" Base Transceiver Station equipments (BTS), one for each cell. However, the study of such a split is outside the scope of the 08.0x series of Technical Specifications, where the BSS will be considered as a whole.
The BSS-MSC interface defined in the 3GPP TS 08 series of Technical Specifications is designed to support a wide range of possible architectures on both sides. Characteristics like the physical location of the transcoders/rate adaptation inside the BSS (either integrated into the transceivers or very near to the MSC) or the use of traffic or signalling concentration at either side are left to the operators choice. Annex A to the present document contains guidance information concerning the use of remote mobile switching units, which for the purposes of the present document are considered as part of the MSC.
Direct connection between two BSSs is not supported by this interface.
This interface is based on the use of 1 or more 2 048 kbit/s digital transmission system interfaces. Each 2 048 kbit/s interface provides 31*64 kbit/s channels which can be used for traffic or signalling as the operator requires.
The signalling is layered, terminology similar to that in the OSI reference model is used in this series, however the layers referred to are not identical to the equivalently named layer in the OSI model.
This interface is defined at the boundary of the MSC and has a per channel bit rate of 64 kbit/s, but the net radio path traffic channel is at a rate of less than 16 kbit/s. A transcoder or rate adapter function is thus needed for the rate conversion. The interface is designed such that the transcoding or rate adaptation function may be geographically situated at either the MSC site or the BSS site, however the transcoder is considered to be part of the BSS.
The interface has been designed around the aims of 3GPP TS 08.01 allowing each component and the system as a whole to evolve. |
08.04 | Base Station System - Mobile Services Switching Centre (BSS-MSC) Interface Layer 1 Specification | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.04/0804-801.zip | The present document defines the structure of the physical layer (layer 1) of the BSS-MSC interface for supporting traffic channels. Use of the physical layer for supporting Signalling System No.7 signalling links is covered in Technical Specification 3GPP TS 08.06.
The physical layer is the lowest layer in the OSI Reference Model and it supports all functions required for transmission of bit streams on the physical medium.
For the present document only digital transmission will be considered, the use of analogue transmission is a national concern. |
08.06 | Signalling Transport Mechanism Specification for the Base Station System - Mobile Services Switching Centre (BSS-MSC) Interface | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.06/0806-801.zip | The present document is split into two parts, clause 1-4 dealing with the MTP and clauses 5-7 dealing with the SCCP and its use.
The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 1-4 of the present document deal with the subset of the MTP that can be used between an BSS and an MSC, which is compatible with a full MTP.
The SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a particular call. Clauses 5-7 identify the SCCP subset that should be used between a BSS and an MSC. The SCCP can also be used to enhance the message routing for (for instance) operations and maintenance information. |
08.08 | Mobile-services Switching Centre - Base Station system (MSC-BSS) Interface Layer 3 Specification | TS | 8.15.0 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.08/0808-8f0.zip | The present document specifies the layer 3 procedures used on the Base Station System (BSS) to Mobile-services Switching Centre (MSC) interface for control of GSM services.
For the purposes of call control and mobility management, messages are not interpreted at the Base Station System (BSS) which acts as a relay function. These messages and procedures are documented in 3GPP TS 04.08, the only relevant issues covering these messages in the present document are those concerned with error conditions at the interface, and the headers that are required for the correct addressing of the messages. This is specified in more detail in 3GPP TS 08.06.
The functional split between MSC and BSS is defined in 3GPP TS 08.02 and states that the BSS is responsible for local radio resource allocation and in order to support this the required procedures between BSS and MSC are defined in detail in the present document.
3GPP TS 08.02 also states that the BSS is responsible for the scheduling of all CCCH/BCCH messages and therefore some procedures for providing the BSS with the necessary information to be passed on these channels for individual calls (i.e. paging) are defined in the present document, but the scheduling is not discussed.
This interface and consequently these layer 3 procedures are designed to support BSSs providing one or more cells. |
08.14 | General Packet Radio Service (GPRS); Base Station System (BSS) - Serving GPRS Support Node (SGSN) interface; Gb Interface Layer 1 | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.14/0814-801.zip | The present document specifies the physical layer on the Base Station System (BSS) to Serving GPRS Support Node (SGSN) interface (Gb interface) and references layer 1 standards to be used on this interface.
The protocol stack on the Gb interface is defined in the stage 2 3GPP TS 03.60 [3]. |
08.16 | General Packet Radio Service (GPRS); Base Station System (BSS) - Serving GPRS Support Node (SGSN) Interface; Network Service | TS | 8.0.1 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.16/0816-801.zip | The present document specifies the Network Service used on the Base Station System (BSS) to Serving GPRS Support Node (SGSN) interface (Gb interface).
The protocol stack on the Gb interface is defined in the stage 2 Technical Specification 3GPP TS 03.60 [1].
The Network Service entity provides network services to the BSSGP entity specified in 3GPP TS 08.18 [2].
The layer 1 of the Gb interface is specified in 3GPP TS 08.14 [3].
In the present document, the communication between adjacent layers and the services provided by the layers are distributed by use of abstract service primitives. But only externally observable behaviour resulting from the description is normatively prescribed by the present document.
The service primitive model used in the present document is based on the concepts developed in CCITT Recommendation X.200 [4]. |
08.18 | General Packet Radio Service (GPRS); Base Station System (BSS) - Serving GPRS Support Node (SGSN); BSS GPRS Protocol | TS | 8.12.0 | R6 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.18/0818-8c0.zip | The present document specifies or references procedures used on the Base Station System (BSS) to Serving GPRS Support Node (SGSN) interface for control of GSM packet data services.
The functional split between BSS and SGSN is defined in 3GPP TS 03.60 [7] which states that a BSS is responsible for local radio resource allocation. The required procedures between BSS and SGSN are defined in detail in the present document. |
08.20 | Rate Adaptation on the Base Station System - Mobile Service Switching Centre (BSS-MSC) Interface | TS | 8.4.1 | C3 | https://www.3gpp.org/ftp/Specs/archive/08_series/08.20/0820-841.zip | The present document defines rate adaptation functions to be used in GSM PLMN Base Station Systems (BSS) transcoders and IWF for adapting radio interface data rates to the 64 kbit/s used at the A-interface in accordance with 3GPP TS 03.10.
The number of Base Station System - Mobile-services Switching Centre (BSS - MSC) traffic channels supporting data rate adaptation may be limited. In this case some channels may not support data rate adaptation. Those that do, shall conform to this specification.
NOTE: This specification should be considered together with 3GPP TS 04.21 to give a complete description of PLMN rate adaptation. |
