ETSI TISPAN – 3GPP NGN WORKSHOP ETSI–3GPP NGN ACTIVITIES Ericsson, Lucent Technologies, Nokia, Nortel Networks, Siemens
ASSUMPTIONS • ETSI TISPAN IP Multimedia Subsystem (IMS) is based on 3GPP Specifications • 3GPP is not defining the NGN but will work with TISPAN to establish a common approach to enable IMS as an NGN platform • TISPAN will define NGN session control using IMS as a platform
3GPP – TISPAN NGN Cooperation • 3GPP NGN dependencies & priorities monitored by TISPAN • Coordination by TISPAN and communicating to TSG SA & CN on NGN issues • TISPAN and 3GPP members need to coordinate to drive the NGN platform standardization activities • Interested 3GPP Individual Members shall drive WIDs, as appropriate, within the 3GPP Working Groups • It is the responsibility of 3GPP Individual Members to drive the NGN platform standardization activities within 3GPP WGs
Potential WIDs within 3GPP • WID – System impact from providing IMS services via fixed broadband • Issues • SIP sessions tunneled through NATs • Presence extension to support PSTN/ISDN users • NGN Charging Requirements • Simulate existing PSTN/ISDN services • Leading WG: SA2 • Involved WG: SA1, SA3, SA5 • WID – Protocol impact from providing IMS services via fixed broadband • Issues • Simulate existing PSTN/ISDN services • Presence extension to support PSTN/ISDN users • NGN QoS Requirements • Leading WG: CN1 • Involved WG: CN3, CN4
List of existing Work Items with potential interest • All-IP Feasibility Study • Architectural Enhancements for E2E Quality of Service • WLAN - UMTS Interworking • QoS Improvements • Gq interface specification for Dynamic Policy control enhancements • Interworking aspects and migration scenarios for IPv4 based IMS Implementations • Interoperability and Commonality between IMS using different "IP-connectivity Networks“ • IP flow based bearer level charging
3GPP NGN Dependencies and Priorities EXAMPLE http://www.3gpp.org/TB/Other/IETF.htm
SUMMARY • 3GPP drives & maintains IMS core specifications • Single set of specs (for Core IMS) is the goal • TISPAN develops independent set of specifications, not regarded as in the IMS core; • TISPAN coordinates “3GPP NGN Dependencies & Priorities” on issue level • It is the responsibility for companies to contribute to 3GPP to introduce support for an NGN platform • Joint understanding of IMS platform requirements for NGN approval within 3GPP • Other areas of cooperation of further discussion, e.g. WLAN
