2 Motivations of this Contribution Help femto network spec standardization move forward Focus on 1x/DO femto cell network spec Specify secure tunnel (between Femto cell and Security Gateway) specification regardless of architecture choice

3 Standardization Plans Create a multi-part document –Part 000: Femto Network Spec Overview (PDS) –Part 100: Secure Tunnel Specification (Including Authentication/Authorization and Tunnel QoS) (PDS and TSG-A) –Part 200: Split functions between PDSN and Femto Cell (including IP address assignment, handoff, and, Relay AAA, Relay MIP, Accounting) (PDS and TSG-A) –Part 500: IMS/SIP-based Related Spec (MMD) Schedule : –4Q-2008: Baseline the document
