2. Outline Joint Proposed Architecture Functional Partitioning Recommendations

3. Proposed Architecture AAG may perform additional functions as required by other technologies

4. Functional Partitioning AAG (Access Agnostic Gateway):  AAA client for AAA transactions  IDS (Intrusion Detection System)/IPS (Intrusion Prevention System) access point  Hot-lining device  Prepaid client/Online charging (Diameter)  Foreign Agent (FA) for MIPv4  Network Mobility Agent for localized network mobility (NMA)  QoS enforcement point (Marking and shaping based on Ty policies)  Policy enforcement point including charging rules etc (PCEF)  NFCC (Network Firewall Configuration and Control) packet filter (optional)  Accounting Storage/Forwarding for UDR coming from BS BS (Base Station):  PMIP Client  AAA Client sends UDRs to AAG  NFCC (to deal with reverse link traffic at the entry point, optional)  IDS (Intrusion Detection System)/IPS (Intrusion Prevention System) (optional)  Radio Link Function Header Compression IP Packet Classifier for over the air QoS treatment QoS and Policy enforcement  Authenticator  Paging

5. Interfaces The interface between AAG and BS:  Interface for policy and session QoS (e.g., Ty relay)  AAA protocol  IETF network based mobility protocol (Proxy MIP) Inter eBS Interface:  L3 (IP Data) tunnel  L2 Data tunnel Carries OTA signaling messages between AT and non serving eBS Carries partial-data between AT and non serving eBS.  CTP (Context Transfer Protocol) L2 context transfer L3 context transfer  Registration, Paging, etc

6. Some Highlights IETF standard protocol must be used for inter-AAG interface if needed CMIP is used for inter-technologies handoff

7. Recommendations 3GPP2 must standardize only one profile in evolution architecture 3GPP2 should expedite the network evolution progress  Adopt the proposed architecture and functional partitioning  Start to work on technical specifications
