22.101 | Service aspects; Service principles | TS | 20.0.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.101/22101-k00.zip | This Technical Specification (TS) describes the Service Principles for PLMNs specified by 3GPP. Principles and requirements for interworking with WLAN are covered in TS 22.234 [35].
3GPP specifications provide integrated personal communications services. The system will support different applications ranging from narrow-band to wide-band communications capability with integrated personal and terminal mobility to meet the user and service requirements of the 21st century.
3GPP specifications allow the realisation of a new generation of mobile communications technology for a world in which personal communications services should allow person-to-person calling, independent of location, the terminal used, the means of transmission (wired or wireless) and the choice of technology. Personal communication services should be based on a combination of fixed and wireless/mobile services to form a seamless end-to-end service for the user.
3GPP specifications should be in compliance with the following objectives:
a) to provide a single integrated system in which the user can access services in an easy to use and uniform way in all environments;
b) to allow differentiation between service offerings of various serving networks and home environments;
c) to provide a wide range of telecommunications services including those provided by fixed networks and requiring user bit rates of up to 100 Mbit/s as well as services special to mobile communications. These services should be supported in residential, public and office environments and in areas of diverse population densities. These services are provided with a quality comparable with that provided by fixed networks such as ISDN and fixed broadband Internet access;
d) to provide services via hand held, portable, vehicular mounted, movable and fixed terminals (including those which normally operate connected to fixed networks), in all environments (in different service environments - residential, private domestic and different radio environments) provided that the terminal has the necessary capabilities;
e) to provide support of roaming users by enabling users to access services provided by their home environment in the same way even when roaming.
f) to provide audio, data, video and particularly multimedia services;
g) to provide for the flexible introduction of telecommunication services;
h) to provide within the residential environment the capability to enable a pedestrian user to access all services normally provided by fixed networks;
i) to provide within the office environment the capability to enable a pedestrian user to access all services normally provided by PBXs and LANs;
j) to provide a substitute for fixed networks in areas of diverse population densities, under conditions approved by the appropriate national or regional regulatory authority.
k) to provide support for interfaces which allow the use of terminals normally connected to fixed networks. |

[The present document develops recommendations for potential normative work on an ultra-low bit rate codec for the use case of IMS voice services over Geostationary Orbit (GEO) access.]
Editor’s Note:
3GPP SA1 has studied the use case IMS Voice Call Using GEO Access, and the results are documented in TR 22.887. Normative service requirements and KPIs on IMS voice call using GEO satellite access will be introduced in TS 22.261 at TSG#107. GEO satellites are on a 35,786 km distance from the earth, which noticeably impacts signal propagation delay (one way approx. 285ms), data rate, and channel conditions due to e.g. atmospheric attenuation. Compared to terrestrial links, this poses significant new challenges for the voice codecs and services:
The overall transmission data rate assumed for GEO satellite systems is very constrained due to e.g. high path loss, atmospheric attenuation, energy constraints for terminals etc.. In TR 22.887, a total transmission data rate of [1-3] kbit/s is assumed. This transmission data rate are lower than what current 3GPP protocol stacks and codecs can supports.
For GEO satellite access, the propagation delay (285ms) is much longer than for commonly used terrestrial links.
The GEO satellite link imposes different channel characteristics, e.g., due to atmospheric attenuation.
Currently, no 3GPP voice codec seems to support all the expected requirements for this use case. Considering bitrate alone, the lowest supported bitrate of any 3GPP codec is 4.75 kbit/s as provided by the narrow band AMR codec (TS 26.071). This makes it necessary to have a new feasibility study relating to ultra-low bitrate codecs suitable for voice using GEO access.
The primary focus of this study is to develop design constraints and performance requirements for a codec supporting use cases like IMS Voice Call over GEO and the resulting transmission parameters. The requirements can provide guidance on the evaluation of the candidate codecs during potential normative work.
1. General considerations
- Bitrate: TR 22.887 concludes that the transmission rates are lower than what current 3GPP protocol stacks and codecs can supports. Detailed analysis on available bitrate requires more study..
- Quality: Despite of the low bit rate, a good audio quality of the codec is of importance, to ensure a reasonable QoE. Detailed QoE requirements for such services are for study..
- Complexity and memory demands: Modern low bitrate codecs exhibit a large scale of complexity and memory demands. The codec is expected to be deployable on the processing capabilities as can be found in today’s smartphones. Exact complexity requirements are for study.
- Robustness to network conditions: the codec is expected to operate in typical network conditions (delay, loss, jitter, etc.). Details are for further study.
2. Functional requirements
- Speech transcoding functions: To achieve integration with the terrestrial voice communication system (4G/5G IMS architecture), it is necessary to consider tandeming with existing IMS voice codecs.
NOTE: Additional study areas or use cases, such as assessing the market potential and potential market-readiness of a new ULBC codec should be added with lower priority if time permits and once the exact requirements can be given.
It is expected that coordination with other working groups, e.g. SA2, CT1, RAN2 is needed in order to substantiate the design constraints of such a codec. However, it is not expected that this work creates any dependency for studies and normative in other working groups. |

22.840 | Study on Ambient power-enabled Internet of Things | TR | 19.0.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.840/22840-j00.zip | The present document provides Stage 1 potential 5G service requirements for ambient power-enabled Internet of Things (i.e., Ambient IoT). In the context of the present document, an Ambient power-enabled IoT device is an IoT device powered by energy harvesting, being either battery-less or with limited energy storage capability (e.g., using a capacitor) and the energy is provided through the harvesting of radio waves, light, motion, heat, or any other suitable power source. An ambient IoT device is expected to have lower complexity, smaller size and reduced capabilities and lower power consumption than previously defined 3GPP IoT devices (e.g., NB-IoT/eMTC devices). Ambient IoT devices can be maintenance free and can have long life span (e.g., more than 10 years).
The aspects addressed in the present document include:
• Study use cases of ambient power-enabled IoT and identify potential service requirements, including:
▪ Security aspects, e.g., authentication and authorization, etc.
▪ Network selection, access control, connection, mobility and identification management
▪ Charging (e.g., per data volume, per message)
▪ Aspects related to stakeholder models (e.g., involving interactions in PLMNs, NPNs or other parties)
▪ Positioning
▪ Aspects on device life cycle management related to 3GPP system.
• Study traffic scenarios, device constraints (e.g., power consumption) and identify potential performance requirements and KPIs
• Gap analysis between the identified requirements for ambient power-enabled IoT and what is already defined by existing 3GPP requirements.
Note: How Ambient IoT device performs energy harvesting is out of scope of this technical report. |
22.841 | Study on Upper layer traffic steering, switching and split over dual 3GPP access | TR | 19.0.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.841/22841-j00.zip | The scope of this TR is to document use cases, gap analysis and potential service requirements related to 5GS support of enhanced mechanisms for steering, splitting and switching of user data, pertaining to a UE data session, across two 3GPP networks. The following scenarios are covered, where only one single PLMN subscription is assumed:
• Single PLMN;
• PLMN and NPN;
• two PLMNs.
The two 3GPP networks may use same or different RAT, i.e. NR plus NR or E-UTRA, where NR RAT can be terrestrial or satellite NR access (including different staellite orbits, e.g., GEO/MEO/LEO).
For the PLMN plus PLMN / NPN scenarios, the two networks can be managed by the same operator or by different operators (assumed to have a business agreement among them). In both cases, it is assumed that a single PLMN subscription is used to access both networks (including the NPN).
Simultaneous connectivity over two 3GPP networks presumes UE support of proper capabilities (e.g., dual radio).
It is assumed that there are no impacts to normal inter-PLMN roaming scenarios.
Dual subscription scenarios are not in scope of this TR. |
22.843 | Study on on Additional capabilities of mobile networks for drone operations and managements | TR | 19.2.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.843/22843-j20.zip | The present document provides additional use cases of UAV and identifies potential requirements to improve 5G system’s support of UAV applications, UAV operations and management, including:
• Provide additional information to the UAV operator/USS to execute pre-flight preparations and inflight operation (e.g, flight mission application, flight path recommendation, flight monitoring and control);
• Use 5G system to support enhancing the UAV flight/route management based on network capacity and QoS information along the planned route;
• Use 5G system to further enhance the safety and security of UAV operations, e.g. supporting UTM in UAV detection and DAA (Detect and Avoid);
• Identify potential new security, charging and regulatory requirements on 5GS, when used for UAS operation;
• Identify potential new requirements related to redundancy and reliability of command and control (C2) traffic for UAV.
For the identified use cases, a gap analysis is performed between potential new service requirements and existing 3GPP requirements and functionalities.
NOTE: This study investigates requirements for additional 5GS capabilities to assist UTM, with the assumption that liability and responsibility for UAV operation remain under the domain of the UTM/UAV operator.
NOTE: Potential overlaps with ongoing stage-2 work (on UAS), and other SA1 studies (e.g. FS_Sensing) have been considered and avoided. |

Potential service requirements are derived for these use cases and are consolidated in a dedicated chapter.
The report ends with recommendations regarding the continuation of the work.
NOTE: There is no requirement for a PLMN to enhance their interconnect with SNPNs or operate an identity provider. |

The study is led by TSG SA in close collaboration and inputs from TSG CT and TSG RAN. |
22.851 | Study on Network Sharing Aspects | TR | 19.1.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.851/22851-j10.zip | The present document investigates use cases and potential new requirements related to 3GPP system enhanced support of specific 5G network sharing deployment scenarios, in particular where there is no direct interconnection between the shared NG-RAN and participating operators’ core networks. It includes the following aspects:
- Mobility and service continuity, e.g., when moving from a non-shared 4G/5G network to a shared 5G network and vice versa, with focus on CN aspects.
- Potential security requirements.
- Charging requirements (e.g., based on traffic differentiation in specific network sharing geographical areas).
- User/service experience (e.g., maintain the communication latency for voice, and SMS) when accessing the shared network, including scenarios of home-routed traffic or local breakout.
- Other aspects, e.g., regulatory requirements, emergency services, PWS support. |
22.856 | Study on Localized Mobile Metaverse Services | TR | 19.2.0 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.856/22856-j20.zip | The present document investigates specific use cases and service requirements for 5GS support of enhanced XR-based services, (as XR-based services are an essential part of "Metaverse" services considered in this study,) as well as potentially other functionality, to offer shared and interactive user experience of local content and services, accessed either by users in the proximity or remotely. In particular, the following areas are studied:
- Support of interactive XR media shared among multiple users in a single location, including:
- performance (KPI) aspects; e.g. latency, throughput, connection density
- efficiency and scalability aspects, for large numbers of users in a single location.
- the combination of haptics type of XR media and other non-haptics types of XR media.
- Identification of users and other digital representations of entities interacting within the Metaverse service.
- Acquisition, use and exposure of local (physical and digital) information to enable Metaverse services, including:
- acquiring local spatial/environmental information and user/UE(s) information (including viewing angle, position and direction);
- exposing local acquired spatial, environmental and user/UE information to 3rd parties to enable Metaverse services.
- Other aspects, such as privacy, charging, public safety and security requirements.
The study also investigates gaps between the identified new potential requirements and the requirements already specified for the 5G system.
It is acknowledged that there are activities related to the topic Metaverse outside of 3GPP, such as the W3C Open Metaverse Interoperability Group (OMI). These activities may be considered in the form of use cases and related contributions to this study, but there is no specific objective for this study to consider or align with external standardization activities.
A difference between this study and TR 22.847 " Study on supporting tactile and multi-modality communication services" is that Metaverse services would involve coordination of input data from different devices/sensors from different users and coordination of output data to different devices at different destinations to support the same task or application. |

• Store and Forward (S&F) Satellite operation for delay-tolerant communication service
• UE-Satellite-UE communication
• GNSS independent operation
• Positioning enhancements for satellite access
Potential service requirements are derived for these use cases and are consolidated in a dedicated chapter.

• Welcome SMS
• Steering of Roaming (SoR) during the registration procedure
• Subscription-based routing to a particular core network (e.g., in a different country)
Potential requirements are derived for these three services and consolidated in a dedicated chapter. The report ends with recommendation regarding the continuation of the work.
NOTE: This document is not expected to introduce any changes to the security mechanisms between operators, and responsible groups will verify that 5GS security mechanisms are not negatively impacted by these requirements. |

23.003 | Numbering, addressing and identification | TS | 19.3.0 | C4 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.003/23003-j30.zip | The present document defines the principal purpose and use of different naming, numbering, addressing and identification resources (i.e. Identifiers (ID)) within the digital cellular telecommunications system and the 3GPP system.
IDs that are covered by this specification includes both public IDs, private IDs and IDs that are assigned to MSs/UEs. Many of the IDs are used temporary in the networks and are allocated and assigned by the operators and some other IDs are allocated and assigned on either global, regional and national level by an administrator. See ITU-T Recommendation E.101 [122].
NOTE: Allocation means the process of opening a numbering, naming or addressing resource in a plan for the purpose of its use by a telecommunication service under specified conditions. The allocation in itself does not yet give rights for any user, whether an operator, service provider, user or someone else, to use the resource. Assignment means authorization given to an applicant for the right of use of number, naming or addressing resources under specified conditions.
The present document defines:
0) the principal purpose and use of International Mobile station Equipment Identities (IMEI) within the digital cellular telecommunications system and the 3GPP system
a) an identification plan for public networks and subscriptions in the 3GPP systems;
b) principles of assigning telephone numbers to MSs in the country of registration of the MS;

The present document specifies functions, procedures and information which apply to GERAN Iu mode. However, functionality related to GERAN Iu mode is neither maintained nor enhanced. |
23.007 | Restoration procedures | TS | 19.2.0 | C4 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.007/23007-j20.zip | The data stored in location registers are automatically updated in normal operation; the main information stored in a location register defines the location of each mobile station and the subscriber data required to handle traffic for each mobile subscriber. The loss or corruption of these data will seriously degrade the service offered to mobile subscribers; it is therefore necessary to define procedures to limit the effects of failure of a location register, and to restore the location register data automatically. The present document defines the necessary procedures.
The basic principle is that restoration should be based on radio contact to avoid faulty data being spread in the system.
Subscriber data for supplementary services must also be correctly restored, although the impact on service of corruption of supplementary service data is less severe.
Procedures for supporting these functions are defined in 3GPP TS 29.002 [6] and 3GPP TS 29.060 [8].
The MAP operation "IMSI Attach" is used only in MAP version 1; in MAP version 2 the same function is performed by the MAP operation "Update Location Area". References in this specification to IMSI attach apply only to MAP version 1 network entities.
If the restoration of subscriber data in the VLR is triggered by Location Updating or IMSI Attach, the VLR retrieves subscriber data from the HLR by sending an "Update Location" request, which triggers one or more "Insert Subscriber Data" operations from the HLR. The "Update Location" request may also be used to send the LMSI to the HLR.
If the restoration of subscriber data in the VLR is triggered by a "Provide Roaming Number" request, the behaviour of the VLR depends on whether it is implemented according to MAP version 1 or MAP version 2. For MAP version 2, the VLR retrieves subscriber data from the HLR by sending a "Restore Data" request, which triggers one or more "Insert Subscriber Data" operations from the HLR. The "Restore Data" request is also used to send the LMSI to the HLR. For MAP version 1, the VLR retrieves subscriber data from the HLR by sending a "Send Parameters" request with parameter type "Subscriber Data", which cannot be used to send the LMSI to the HLR.
The VLR number and MSC number in the subscriber data in the HLR are updated by the "Update Location" procedure.
The GGSN (Gateway GPRS Support Node) is the point of PDN interconnection with the GSM PLMN supporting GPRS. The GGSN contains routing information for GPRS users with a PDP context active. The necessary procedures needed to restore GGSN data information after a restart are described in this document.
The SGSN (Serving GPRS Support Node) is the node that is serving the MS. The SGSN stores information regarding e.g. mobility management, routing and security. The necessary procedures needed to restore this SGSN information after a restart are described in this document.
The MME (Mobility Management Entity) is the node that is serving the UE when attached to E-UTRAN. The MME stores information regarding e.g. mobility management, routing and security. The necessary procedures needed to restore this MME information after a restart are described in this document.
A Type A LMU (Location Measurement Unit) is a network node, accessed over the GSM air interface, that is functionally similar to an MS. All requirements associated with a non-GPRS MS in this specification apply also to a Type A LMU except where specified otherwise. |
23.008 | Organization of subscriber data | TS | 19.0.0 | C4 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.008/23008-j00.zip | The present document provides details concerning information to be stored in the different entities storing data within a 3GPP network concerning mobile subscriber. A list of entities storing subscriber data is provided in clause 1.
Clause 2 contains all details concerning the definition of the parameters, often given by reference to other specifications, and where the parameter is to be stored.
Table 1 in clause 3 gives a summary overview and clause 4 identifies the reference information required for accessing the information.
In this specification, if there is no specific indication, the following principles apply:
- "SGSN" refers to an SGSN which may support the Gn and Gp interfaces or the S4 interface or both.
- "S4-SGSN" refers to an SGSN which only supports the S4 interface.
- "Gn/Gp-SGSN" refers to an SGSN which only supports the Gn and Gp interfaces. |
23.015 | Technical realization of Operator Determined Barring (ODB) | TS | 19.0.0 | C4 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.015/23015-j00.zip | The network feature Operator Determined Barring (ODB) allows a network operator or service provider to regulate access by subscribers to services (Circuit/Packet Oriented and Interworking WLAN), by the barring of certain categories of incoming or outgoing calls/ Packet Oriented Services or of roaming. Operator Determined Barring applies to all bearer services and teleservices except the Emergency Call teleservice and Emergency Bearer Services; the teleservice Short Message Point-to-Point is therefore subject to Operator Determined Barring in the same way as circuit-switched calls.
The application of specific categories of Operator Determined Barring to a subscription is controlled by the network operator or service provider, using administrative interaction at the HLR; this interface is not standardised. |
23.041 | Technical realization of Cell Broadcast Service (CBS) | TS | 19.1.0 | C1 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.041/23041-j10.zip | The present document describes the Cell Broadcast short message service (CBS) for GSM and UMTS.
For GSM it defines the primitives over the Cell Broadcast Centre - Base Station System (CBC-BSS) interface and the message formats over the Base Station System - Mobile Station (BSS-MS) interface for Teleservice 23 as specified in 3GPP TS 22.003 [2].
For UMTS it defines the interface requirements for the Cell Broadcast Centre – UMTS Radio Network System (RNS) interface and the radio interface requirements for UMTS Radio Acces Networks to support CBS as specified in 3GPP TS 22.003 [2].
The present document also describes the Public Warning System (PWS) for GSM, UMTS, E-UTRAN, satellite E-UTRAN, NG‑RAN, and satellite NG-RAN, see 3GPP TS 22.268 [28]. |
23.122 | Non-Access-Stratum (NAS) functions related to Mobile Station (MS) in idle mode | TS | 19.3.0 | C1 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.122/23122-j30.zip | The present document gives an overview of the tasks undertaken by the Core network protocols of a Mobile Station (MS) when in idle mode, that is, switched on but typically not having a dedicated channel allocated. 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 conditions when the idle mode functions are performed by an MS in the UTRA RRC connected mode states are specified in 3GPP TS 25.331 [33]. The conditions when the idle mode functions are performed by an MS in the E-UTRAN are specified in 3GPP TS 36.304 [43]. The conditions when the idle mode functions are performed by an MS in the NG-RAN are specified in 3GPP TS 36.304 [43] and 3GPP TS 38.304 [61]. The conditions when the idle mode functions are performed by an MS in the NG-RAN RRC inactive state are specified in 3GPP TS 36.331 [42] and 3GPP TS 38.331 [65].
The present document defines the PLMN selection for a multi mode MS that supports both 3GPP and 3GPP2 systems. The common PLMN selection logic covers also PLMNs that are available in 3GPP2 system, but the present document makes no changes on the cdma2000® signalling towards networks that are available via 3GPP2 system.
The present document gives procedures for using the CSG cells, whenever such use is permitted.
The present document gives procedures for using the CAG cells, when the MS supports CAG.
The present document specifies the SNPN selection.
This 3GPP TS outlines how the requirements of the 22 series Technical Specifications (especially 3GPP TS 22.011 [9]) on idle mode operation shall be implemented. Further details are given in 3GPP TS 24.008 [23].
Clause 2 of this 3GPP TS 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.
NOTE: cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA).
The present document describes the procedures for control plane solution of steering of roaming in 5GS in annex C.

This document does not cover the Access Network functionality except as they relate to provision of IM services, these aspects are covered in the normative Annexes.
This document identifies the mechanisms to enable support for IP multimedia applications. In order to align IP multimedia applications wherever possible with non-3GPP IP applications, the general approach is to adopt non-3GPP specific IP based solutions. |
23.272 | Circuit Switched (CS) fallback in Evolved Packet System (EPS); Stage 2 | TS | 19.1.0 | S2 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.272/23272-j10.zip | This document defines the Stage 2 architecture and specification for the CS Fallback and for SMS over SGs for EPS or CS Fallback and SMS over S102. The scope of this document includes the architecture enhancements for functionality to enable fallback from E-UTRAN access to UTRAN/GERAN CS domain access and to CDMA 1x RTT CS domain access, and functionality to reuse of voice and other CS-domain services (e.g. CS UDI video / LCS / USSD) by reuse of the CS domain. The functionality specified to support SMS over SGs does not trigger any CS Fallback to UTRAN/GERAN. The functionality specified to support SMS over S102 does not trigger any CS Fallback to CDMA 1xRTT CS domain.
In addition this specification includes an SMS in MME architecture option for SMS services only. This functionality does not trigger any CS Fallback and does not require SGs.
The architecture enhancements to support CS fallback to CDMA 1x RTT CS domain access for UEs with single and dual receiver configurations are specified in Annex B.
In this Release of the specification no mechanisms are specified to support CS Fallback to both UTRAN/GERAN and CDMA 1xRTT in the same PLMN. So, even when a UE has the capability to support both CS Fallback to UTRAN/GERAN CS domain and CS Fallback to CDMA 1xRTT CS domain in a given PLMN, the PLMN implements only one of the two. |
