Working group

The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs).  Core Network and Terminals (CT) has four active working groups.

TSG CT1 (MM/CC/SM [lu]) is responsible for the 3GPP specifications that define the User Equipment - Core network L3 radio protocols and Core network side of the Iu reference point.

Specifically, CT1 is responsibility for:

CT1 also has maintenance responsibility of older versions of the specifications under its responsibility.

The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs).

Core Network and Terminals WG3 - CT WG3 (Interworking with External Networks) specifies the bearer capabilities for circuit and packet switched data services, and the necessary interworking functions towards both, the user equipment in the UMTS PLMN and the terminal equipment in the external network. In addition:

• CT3 Is responsible of end to end QoS for the UMTS core network in Release 5 and beyond.
• CT3 has important dependencies with the following work performed in other 3GPP groups, e.g. SA1-2-3-4-5-6; RAN3 and CT1 and 4.

CT WG4 - MAP/CAMEL/GTP/BCH/SS (TSG Core Network and Terminals WG4) standardises stage 2 and stage 3 aspects within the Core Network focusing on:

• Supplementary Services.
• Basic Call Processing.
• Mobility Management within the Core Network.
• Bearer Independent Architecture.
• GPRS between network entities.
• Transcoder Free Operation.
• CAMEL.
• Generic User Profile.
• Wireless LAN - UMTS interworking and descriptions of IP Multimedia Subsystem.

CT WG4 is also responsible as a "protocol steward" for the some IP related protocols (this involves analysing, validating, extending if necessary, clarifying how they are used, specifying packages and parameter values).

The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs).

CT WG6 (smart card application aspects) is responsible for Development and maintenance of specifications and associated test specifications for the 3GPP smart card applications, and the interface with the Mobile Terminal. 

Including: 

• Subscriber Identity Module (SIM) which is used by 2G systems.
• USIM (Universal Subscriber Identity Module) which is used by 3GPP systems.
• ISIM (IM Services Identity Module) with the exception of the security algorithms (developed by SA WG3). 

We are a joint Technical Committee (EBU, CENELEC and ETSI) co-ordinating the drafting of standards in the field of broadcasting and related fields. The Committee assesses the work performed within organizations such as e.g. DVB, WorldDAB, HbbTV, and is responsible for coordinating the drafting of standards for broadcast systems (emission-reception combination) for television, radio, data and other services via satellite, cable and terrestrial transmitters. It includes interactive TV, terrestrial TV, radio (including hybrid radio), satellite TV, fixed line TV, mobile TV and audio technologies.

We are responsible for the creation, development and maintenance of standards and other ETSI deliverables related to integrated broadband cable telecommunication network technologies including:

• network terminals e.g. cable CPE devices and network terminating devices,
• network infrastructure, including network topologies, HFC (hybrid fibre-coax) network distribution, data over cable systems, and frequency management,
• services delivered across integrated broadband cable telecommunication networks,
• energy efficiency and sustainability for integrated broadband cable telecommunication networks,
• security of integrated broadband cable telecommunication networks and services.

We are responsible for the development and maintenance of DECT^TM standards.

ETSI’s DECT specification is the leading standard around the world for digital cordless telecommunications. Over 1 billion devices have been installed worldwide: the system has been adopted in over 110 countries and more than 100 million new devices are sold every year. As the number one cordless system in Europe and the USA, DECT products now account for more than 90% of the world’s cordless market. They are also sold in Japan, where a legislative change has provided more spectrum for license-exempt operation.

At the same time, the specification is being enhanced to include Ultra Low Energy (ULE) products. ULE is the name given to the new networking technology for residential and building applications that is primarily driven by a low power requirement for battery-operated devices. DECT ULE enjoys all the advantages of the DECT spectrum and technology as well as adhering to the technical parameters for the Internet of Things.

A Focus Group on Vehicular Multimedia (FG-VM) has been established to identify the need for new vehicular multimedia standards based on space and terrestrial networks integration. The study will analyze and identify gaps in the vehicular multimedia standardization landscape and eventually draft technical reports and specifications covering, among others, vehicular multimedia use cases, requirements, applications, interfaces, protocols, architectures, and security, leveraging from previous work done by ITU in this field. See more details in the FG-VM terms of reference below.

The ITU/WHO Focus Group on artificial intelligence for health (FG-AI4H) works in partnership with the World Health Organization (WHO) to establish a standardized assessment framework for the evaluation of AI-based methods for health, diagnosis, triage or treatment decisions. Participation in the FG-AI4H is free of charge and open to all. The group was established by ITU-T Study Group 16 at its meeting in Ljubljana, Slovenia, 9-20 July 2018.

As we move forward into the future of automation, AI is proving to play a critical role in the realm of both cyber and cloud security. The ability to learn at the rate which AI produces makes it extremely important to prioritize discovering the potential ways that AI can both assist security, as well as defining ways that standardization can be shaped around its proper uses, ensuring that businesses are prepared for the continued growth of AI. CSA's AI working group has been established to regulate and create a format for which we can begin to shape the future of the frameworks around AI, and the impacts it will have on everyday life involving verticals such as banking, vehicles, big data, as well as other intelligence learning platforms and standards.

IoT devices represent a wide variety of non-traditional devices that are increasingly implemented in organizations due to the numerous benefits. These unique devices often pose a security challenge due to the limited size and lack of innate security making them difficult to secure with traditional security controls and methodologies. It is a combination of these factors that has rendered many devices vulnerable to attacks like the Mirai botnet. The IoT Working Group's mission is dedicated to understanding relevant use cases for IoT deployments and defining actionable guidance for security practitioners to secure their IoT ecosystem. This includes outlining best practices for securing IoT implementations, identifying gaps in standards coverage for IoT security, and identifying threats to IoT devices and implementations.

With today’s fast-evolving threat landscape, a holistic cloud incident response framework that considers an expansive scope of factors for cloud outages is necessary. The working group aims to develop a holistic Cloud Incident Response (CIR) framework that comprehensively covers key causes of cloud incidents (both security and non-security related), and their handling and mitigation strategies. The aim is to serve as a go-to guide for cloud users to effectively prepare for and manage the aftermath of cloud incidents, and also a transparent and common framework for Cloud Service Providers to share with cloud customers their cloud incident response practices. Imperative factors of cloud incidents including, but not limited to, operational mistakes, infrastructure or system failure, environmental issues, cyber security incidents and malicious acts will be included in development of the framework.
