re: 3GPP & 3GPP2 IP Multimedia Core Network Harmonization Workshop Two zipped Word files can be downloaded via FTP summarizing the meetings: ftp://ftp.3gpp2.org/TSGC/Working/2002/TSC-0204/TSG-C-2002_04_Alexandria/Plenary/C00-20020415-029A__IP_CN_2002_043.zip ftp://ftp.3gpp2.org/TSGC/Working/2002/TSC-0204/TSG-C-2002_04_Alexandria/Plenary/C00-20020415-029A__IP_CN_2002_044.zip This excerpt is from the first file: >> Recommendations from April 3-4, 2002 IP CN Harmonization Workshop The following conclusions and recommendations on 3GPP/3GPP2 IP core network harmonization were reached at the IP CN Harmonization Workshop held on April 3-4, 2002 in Toronto, Canada. Harmonization Goals It was agreed that the harmonization of 3GPP/3GPP2 IP Multimedia Core Networks is a worthwhile and achievable goal that should be pursued urgently by both PP groups. It is desirable to focus the harmonization efforts to those areas where synergies already exist. In particular it was agreed that priority will be given to harmonization in the areas of: - OSA/PARLAY based service APIs - IMS (Referring to the 3GPP IP Multimedia Subsystem and its equivalent in 3GPP2 MMD) Given that considerable alignment has already occurred in the area of 3GPP and 3GPP2 IMS, it was further agreed that 3GPP and 3GPP2 should adopt: - A single IMS reference model (at a high level of abstraction, to be extended as appropriate within the 3GPP or 3GPP2) - Consistent terminology to describe common IMS functional entities The reference model and terminology are provided in Annex A. Furthermore, it was agreed that the 3GPP and 3GPP2 should work to ensure: - Interoperability between the 3GPP IMS mobiles and 3GPP2 IMS mobiles (a 3GPP IMS mobile can set up a session with a 3GPP2 IMS mobile and vice-versa) - Application level intersystem IMS roaming (given that the mobile supports the visited network's access network and IP transport technology, a 3GPP IMS mobile should be able to roam into a 3GPP2 network and vice-versa) Annex B provides a non-exhaustive list of issues which 3GPP and 3GPP2 should consider in achieving these interoperability and roaming goals. << Note: The network reference model figure in Annex A in the IP CN Harmonization output document is not visible when Word is in "Normal" view. To see the figure, select the "Print layout" view. - Eric -
