IMS in Fixed Mobile ConvergenceIMS in Fixed Mobile ConvergenceIMS in Fixed Mobile ConvergenceIMS in Fixed Mobile Convergence

Common service machine for NGN

3GPP IMS selected by large number of operators to be the core of nextgeneration fixed network providing voice and multimedia servicesover both

mobile and fixed broadband networks Open interfaces towards terminals, application servers and other networks

Supports mobility between different access networks

Wide range of services

Delivers today wide range of multimedia communication services for mobileterminals (gaming, videosharing, Push to talk etc.)

Supports VoIP service over broadband for multiple different terminals (PCClient, SIP Phone, legacy telephone with analog to SIP adapter)

Enables new multimedia services over broadband (videotelephony, videoconferencing, interworking with mobile multimedia)

Common core IMS architecture and protocolsCommon core IMS architecture and protocolsCommon core IMS architecture and protocolsCommon core IMS architecture and protocols

Common technology in mobile and fixed SIP infra provideseconomies of scale to both the operators and vendors

Operators will have a larger choice of vendors to select fromVendors will be able to create the functionality once, and reuseit later

faster time to market

avoid extra cost from replicating the effort

Common interest for both the operator and the vendor

NGN standardization statusNGN standardization statusNGN standardization statusNGN standardization status

ETSI TISPAN selected 3GPP release 6 IMS to be the baseline forthe SIP service machinery in fixed networks

2nd joint workshop March 2005 Joint work meeting July 2005 in TISPAN#7 and later in the autumn

Possible IMS core changes will be standardized in 3GPP

TISPAN is proceeding fast with the supplementary services

Straightforwardly adding services on top of 3GPP IMS

TISPAN NGN release 1 standard ready by the end of 2005

Also ITU-T and ATIS are adopting the TISPAN IMS standards

The industry as a whole has consensus over the SIP servicemachinery architecture and IMS standards

Multimedia Telephony Capabilities forIMS

The objective is to define the minimumset of capabilities required to securemulti-vendor and multi-operator inter-operability for Multimedia Telephonyand related Supplementary Services.

Close cooperation shall be sought withTISPAN. TISPAN requirements, as

captured in TISPAN-01002-NGN, shallbe taken into account, and referred towhere appropriate.

The objective is to reuse and build onIMS capabilities provided in Release 5

and Release 6."
