Key Industry Groups Chart the Future of IMS

Sophia Antipolis,  5th October 2006

Standards groups and CableLabs have agreed to renew support for 3GPPTM as the centre of expertise on IP Multimedia Subsystem (IMS) as a result of a workshop on the alignment and evolution of IMS held in Palm Springs last week.

The groups in attendance were the 3rd Generation Partnership Project (3GPP*), the European Telecommunications Standards Institute (ETSI), the ETSI Telecoms & Internet converged Services & Protocols for Advanced Networks (TISPAN) Technical Committee and CableLabs with participation by other key standards organizations.

Stephen Hayes, 3GPPTM systems group Chair, said:

'To ensure future interoperability, roaming, and economies of scale, it is important to have a single standard for IMS. With this workshop, we can now say that we have unified support within the industry for that principle'.

PacketCable 2.0, the cable industry's advanced IP services platform, aligns with and enhances the IMS. CableLabs is looking to introduce those enhancements into 3GPP's version of the IMS.

Ed Miller, Vice President of Advanced Network Services at CableLabs, said:

'Although IMS was originally developed for mobile systems, it is now being used by other market segments, so IMS must be more open and flexible to accommodate a diverse set of needs. We are pleased that the outcome of the workshop is a commitment to address requirements from cable and other market segments. That is a good first step, and now we look to 3GPPTM to demonstrate that commitment as we move forward'.

The workshop also addressed the need for closer collaboration between organizations as new services are developed and as IMS is introduced into new markets. Several additions to IMS to support fixed wireless have already been introduced and more are expected.

Rainer Münch, ETSI TISPAN Chairman, said:

'IMS is a key component in Release 1 of TISPAN_NGN, we look forward to a closer collaboration between the standards organizations as we move forward in developing Release 2 of TISPAN_NGN.'

About the 3rd Generation Partnership Projects (3GPPTM)

The 3rd Generation Partnership Project (3GPPTM) was established for the preparation and maintenance of a complete set of globally applicable standards for a Third Generation mobile system based on the evolved ETSI GSM specifications for core networks and the radio access technologies supported by 3GPPTM partners. 3GPPTM membership consists of 3 categories - Organizational Partners (standards organizations), Market Representation Partners (industry associations) and Individual Member companies. Several hundred companies from around the world participate as Individual Members.

TISPAN is the ETSI core competence centre for fixed networks and for migration from switched circuit networks to packet-based networks with an architecture that can serve in both.

Building upon the work already done by 3GPPTM in creating the SIP-based IMS (IP Multimedia Subsystem), TISPAN and 3GPPTM are now working together to define a harmonized IMS-centric core for both wireless and wireline networks.
