  1. Common (cdma2000/umts/edge) All IP Reference Model Chung Liu +1 630-713-4770 czliu@lucent.com Lynne Sinclair +1 630-713-7323 lsinclair@lucent.com

  2. Common All IP ArchitectureObjectives • Define a common All IP Architecture for the prevailing 3G Air Interfaces • UMTS WCDMA • cdma2000 • EDGE • Build from current radio interface, radio access and All IP standards architecture • Radio Interfaces: UMTS, cdma2000 and EDGE • Radio Access Network: 3GPP2 Mobile IP and 3GPP GPRS • All IP Architecture: 3GPP All IP • Inter-operate with legacy systems • Integrate Current IETF industry standards and migrate to All IP architecture • Separate Bearer Control and Call Control Planes • Provide Peer to Peer Networking

  6. Common All IP Architecture for cdma2000, UMTS & EDGE 3GPP2 3GPP Common Services (e.g. SCP) Services and Applications Common Network Element and Function: - CSCF & MRF - T-SGW, MGCF & MGW - Similar HSS, R-SGW Call Control and Gateways M-IP GPRS Common Functions: - QoS (including end-to-end) - Radio bandwidth optimization - etc. UMTS EDGE cdma2000

  7. Common 3GPP2 All IP Network Elements • Call State Control Function (CSCF) or Feature Server • Call control related functionality: Call set-up/termination and control etc. • Location Management related functionality:Registration/VLR, serving FS location etc. • Home Subscriber Server (HSS) • Contains HLR, AAA and UMS (User Mobility Server) • Difference: M-IP uses AAA and GRPS uses HLR • Transport Signalling Gateway Function (T-SGW) • Roaming Signalling Gateway Function (R-SGW) • Media Gateway Control Function (MGCF) • Media Gateway Function (MGW) • Multimedia Resource Function (MRF)

  8. New All IP Interfaces and Protocols (proposed) • Protocol between CSCF and Mobile or IP Phone: • H.323 or SIP • 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) or SIP? • CSCF-Legacy Mobile Network: Ms • IP based signaling • CSCF-Applications/Services: • Difference: Camel (for umts) or ANSI41 (cdma2000) over SS7 or IP (Sigtran) • Real-time IP transport among MS, M-IP & GPRS nodes, MFR, MGW and IP Network: • RTP/UDP/IP

  9. Common 3G All IP Network • A Common 3G All IP Network Architecture has been presented • Designed around carrier expressed needs • interoperability with legacy networks • desire for convergence between 3GPP and 3GPP2 • built from current embedded wireless standards and infrastructure • leverage current VoIP standards and infrastructure
