The document studies: a) the complete harmonization and merger of the policy control and flow based charging architecture and procedures; b) possible architectures and solutions for adding end-user subscription differentiation and general policy control aspects to the policy- and charging control; c) alternative solutions for binding bearers to services (provided today by the authorization token). This includes studying solutions for the network to control bearer usage by service flows.

The document is a study of use cases for multimedia processing in the edge and the potential 5G media streaming architecture extensions to enable them.

The document studies the potential use cases, requirements, and solutions for the management of edge computing architecture and requirement defined by TS 23.558 and TS 23.501. The document provides conclusions and recommendations on the next steps in the standardization.

The present document studies the charging aspects of Edge Computing based on architecture, procedures and information flows for enabling Edge Applications over 3GPP network as well as capabilities for 5GS to support edge computing. The investigation includes different charging scenarios with potential business requirements, alternative solutions with potential impact on charging architecture, charging functions and charging procedures.

The document studies the security enhancements on the support for Edge Computing in the 5G Core network defined in TR 23.748, and application architecture for enabling Edge Applications defined in TR 23.758 and TS 23.558. Potential security requirements are provided and possible security enhancements to 5GS and edge application architecture are proposed that meet these security requirements.

The responsibility of SA WG6 includes the following: definition, evolution and maintenance of Stage 2 technical specification(s) for application layer functional elements and interfaces supporting critical communications and other applications (at the application layer), based on Stage 1 service requirements from SA1, including:

• Relevant application architectural aspects (including both network and terminal aspects)
• Definition of reference points for interactions between application functional elements
• Allocation of application functions to particular subsystems and elements
• Generating information flows between reference points within scope
• Identification of application layer protocols
• Necessary support for enabling interworking with non-3GPP applications
• Identify and provide application level functional requirements to other 3GPP WGs, according to their expertise, where additional functionality needs to be specified that impacts existing architecture, reference points, interfaces, protocols or transport bearer capabilities provided by the 3GPP-based system (e.g. IMS, EPS, ProSe)

Within the 3GPP Technical Specification Group Service and System Aspects (TSG SA), the main objectives of 3GPP TSG SA WG5 (SA5) are Management, Orchestration and Charging for 3GPP systems. Both functional and service perspectives are covered.

TSG SA WG5 is currently responsible for:

• Management and Orchestration which covers aspects such as operation, assurance, fulfilment and automation, including management interaction with entities external to the network operator (e.g. service providers and verticals).
• Charging covers aspects such as Quota Management and Charging Data Records (CDRs) generation, related to end-user and service-provider.

TSG SA WG5 specifies Management, Orchestration and Charging requirements, solutions and protocol-specific definitions. The solutions include architecture, service definitions and data definitions.

TSG SA WG5 is committed to engaging in Management, Orchestration and Charging aspects of supporting new services for public and non-public networks.

TSG SA WG5 coordinates with other 3GPP WGs and all relevant Standards Developing Organizations (SDOs), industry fora and Market Representation Partners (MRPs) as well as Open Source communities in the specification work pertinent to Management, Orchestration and Charging.

SCOPE: The aim of this Technical Report is to study and specify how to collect data and how to feedback data analytics to the network functions.

SCOPE: The present document covers the Radio Access Architecture and Interface aspects of the study item “New Radio Access Technology” [1]. The purpose of this TR is to record the discussion and agreements that arise in the specification of the “New Radio Access Technology” from an Access Architecture and Interface specification point of view.

This 3GPP Technical Specification describes the service and operational requirements for a 5G system, including UE, NG-RAN, and 5G Core network. TS 22.261 builds on specifications for Rel-15 (TS 22.261, V15.7.0). 

TS 22.261 responds to the needs to support different kinds of UEs, e.g. for the Internet of Things (IoT), services and technologies towards a high-performance and highly efficient 3GPP system. Drivers include IoT, Vritual Reality (VR), industrial control, ubiquitous on-demand coverage, and meeting customised market needs. These drivers require enhancements to the devices, services, and technologies well established by 3GPP. 

This specification covers, among other aspects, high level requirements (e.g. migration to 5G). It also covers:

• Basic capabilities, e.g. network slicing, mobility management, multiple access technologies context aware networks, self backhaul, energy efficiency, eV2X aspects, non public networks, QoS monitoring, positioning services.
• Performance requirements, e.g. high data rates, low latency and high reliability. 
• Security, e.g. authentication, authorisation, regulatory aspects, fraud protection, data security and privacy.
• Charging aspects. 

Last update: June 2019

3GPP TS 22.104 (V17.0.0) addresses a challenging class of vertical applications, namely cyber-physical control applications, which require very high levels of communication service availability.  In some cases, they require very low end-to-end latencies. 
Real-time Ethernet is one of the established wireline communication technologies for cyber-physical control applications, and this specification identifies requirements that 5G systems must meet to support real-time Ethernet.

This specification provides new Stage 1 requirements based on the input from relevant stakeholders of the respective vertical domains. Its focus is mostly on factories of the future and electric power distribution. 

TS 22.104 for Rel-17 describes, among other aspects:

• Performance requirements.
• Clock synchronisation requirements.
• Positioning requirements.
• Ethernet applications. 

Related work: It is important to note the co-existing specifications for Rel-16, that is, TS 22.104 V16.2.0.
