  3. New All IP Network Elements • Call State Control Function (CSCF) • Call control related functionality: Call set-up/termination and control etc. • CSCF Location Management related functionality:Registration, serving CSCF location etc. • Address Handling • Home Subscriber Server (HSS) • Contains HLR, AAA and UMS (User Mobility Server) • HLR: mobility related subscriber data for SGSN and GGSN (umts/edge) and network related subscriber data for RAN (cdma2000) • AAA: mobility data for M-IP (cdma2000) • UMS/Location Server: Feature subscriber data base for CSCF • Roaming Signalling Gateway Function (R-SGW) • Signalling interworking with legacy mobile networks (e.g. GSM MAP, ANSI41) • Transport Signalling Gateway Function (T-SWG) • Media Gateway Control Function (MGCF) • Media Gateway Function (MGW) • Multimedia Resource Function (MRF)

  5. New All IP Interfaces and Protocols (proposed) • CSCF-MRF: Mr • H.248/Megaco • CSCF-MGW: Mc • H.248/Megaco • CSCF-HSS: Mp • IP based Interface • CSCF-CSCF: Mw • Bear Independent Control Protocol (BICC) • CSCF-Legacy Mobile Network: Ms • ANSI41 over SS7 or IP (Sigtran) • CSCF-Applications/Services: • Open interface API or Common Protocol over IP • Real-time IP transport among MS, M-IP, MFR, MGW and IP Network: Gi • RTP/UDP/IP • TE/MT and CSCF directly communicate each other with H.323 or SIP

  6. Major 3GPP2 New & Enhanced Functionality • cdma2000 Radio Interface • QoS control and negotiation • Radio Spectrum Efficiency Improvement (e.g. Overhead elimination) • Impact TE/MT, BTS, BSC and Um interfaces • Radio Access Network • QoS control on SDU and existing A interfaces: A3 & A8-11 • Wireless Packet Data Network • New IP Network Elements: HSS, CSCF, MRF, MGCF, TSGW, MGW & R-SGW (see other slide) • Application level interaction with TE/MT • Enhanced PDSN (e.g. QoS and Compression with TE/MT) • End to end Network Architecture and Scenarios • Need standard group to address end to end all IP issues

  7. 3GPP2 All IP Reference Roaming Scenario 1 (Call Control in H-CSCF & HA in Home network) Applications & Legacy mobile Legacy mobile Services signaling signaling Network SCP Network Multimedia Visiting Network Home Network R-SGW IP Networks R-SGW Mh HSS Ms Mp Mm Mw V-CSCF H-CSCF Gi C Mr Mg Pi Mx MRF Gi MGCF T-SGW Gi M-IP TE MT RAN PDSN M-IP HA Mc Gi Gi R Um A PSTN/ MGW Legacy/External Signalling Interface Enhanced Alternatives: 1. 2.

  8. 3GPP2 All IP Reference Roaming Scenario 2 (Call Control in V-CSCF & HA in Visiting Network) Applications & Legacy mobile Legacy mobile Services signaling signaling Network SCP Network Multimedia Visiting Network Home Network R-SGW IP Networks R-SGW Mh HSS Ms Mp Mm Gi M-IP HA V-CSCF H-CSCF C Mw Mx Mg Gi MRF MGCF T-SGW HSS Pi Mc M-IP Gi MGW TE MT RAN M-IP HA PDSN R Um A PSTN/ Legacy/External Signalling Interface Signalling and Data Transfer Interface

  9. 3GPP2 Mobility Considerations (1) • Feature Server Location and Ownership • Visiting Network and Service Provider • Similar to existing wireless network (call control in visiting network) • Home Network and Service Provider • Call control in central location and special local CSCF (e.g. E911) in visiting system • Service Profile Data (SPD) is only in Home Network (even retrieve SPD from HSS during session instead of registration) • Other Network and Service Provider (e.g. Third party) • Feature Server Discovery procedure • Try to be transparent from underlayed protocol & procedure and discover FS anywhere • PSTN to Wireless Call Termination (Call Setup) • All circuit approach (Existing ANSI41 approach: Circuit PSTN-Home-Visiting) - Reuse PSTN, ISUP and ANSI41 • Partially packet approach (Circuit: PSTN-Home & Packet: Home-Visiting) - Reuse PSTN routing in originating network and use packet between home and visiting network (See the following slide) • All packet approach (all packet between originating and visiting network) - PSTN GW in originating network with dedicated DN or IP address

  10. 3GPP2 Mobility Considerations (2) • Traffic Termination Enhancements • Route the traffic directly from originating to visiting network • Avoid IP traffic backhaul to home network always • Have regulatory issues ?? • Home Agent is dynamically assigned by visiting netork • PSTN Gateway in visiting network • 2G and 3G Roaming and handoff Requirement? • All IP and All IP, 2G CS and 3G, 2G IP and All IP • 2G Inter-working via R-SGW

  13. Private Network Gateway (PNGW) • Approach 1: • CSCF translates addresses for signaling • PNGW translates addresses for bearers • Approach 2: • CSCF resolves addresses • PNGW translates addresses for connection control and for bearers

  14. Address Translation Functions • Translate user identifier found in H.225 messages into a local (private) IPv4 address • Peek at the setup CALLED NUMBER or the USER -USER information elements (IE) and stores the CALL REFERENCE VALUE (CRV) • Subsequent H.225 messages are translate using the CRV since the CALLED NUMBER and USER2USER IE’s are not present • Translate H.245 addresses found in CONNECT • Translate TSAP of bearer to private IPv4 address • HSS • Translate E.164 or NAI to a CSCF/PNGW TSAP • Accessed by CSCFs in other networks
