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 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

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."
