  1. Cisco’s Position on All-IP Wireless Networks Presentation_ID

  2. AII IP: Guiding Principles and Architectural Goals • Guiding principles for IP-based wireless networks • Core and Access Networks aligned with Internet model • Align for future multi-service requirements • IP peer to peer model provides flexibility and simplicity in network design • IP architectural goals • Dynamic resource allocation, distributed architecture, and scalability • Air interface independent • Supports 2G & 3G networks • Deliver consistent services across wireless and wireline networks

  3. Circuit/Signaling Gateway Multimedia UnifiedCommunications Packet Voice IP RAN VPN • Operator Benefits: • Rapid Service Deployment • Multimedia Services • Realizing the Full Power of 3G Data True Peer-to-Peer: A Close Look CircuitNetwork Circuit/ Signaling Gateway Packet Circuit Feature Server(s) Traffic Circuit Switching IN Services Services Manager RRC Network Feature Servers Radio Access Control Packet Network (Internet) Packet Gateway IP Network 2G 2.5G / 3G 3G

  4. How to Do the Work: All IP Architecture • Leverage IP technology investments • - Start with wireline IP data and VoIP architecture • Why start from scratch • - Utilize existing IP protocols and services • Use existing work from IETF • - Extend them to support “mobile wireless” access • Focus on “mobile wireless” part • - Mobility management • - Radio resource management • - QoS management for mobile services

  5. Work with Existing IETF Groups • Transport area • QoS: diffserv, intserv, rsvp, issll, ippm • VoIP: avt, mmusic, iptel, sigtran, sip, pint, megaco, hc • Routing area • mobileip, manet, mpls • Security area • ipsec • Operation & Management area • aaa, radius, rap, snmp, tewg

  6. How to Do the Work: Organization (Phase I) • A single group focus on overall architecture • Define the peer-to-peer IP network model • Support inter-operating with legacy networks • Who: TSG-S, TSG-A, TSG-P, or this All-IP Ad Hoc ? • Time period: 3 months ? • How do we get a head start ? • Leverage contributions from Mobile Wireless Internet Forum (MWIF)

  7. How to Do the Work: Organization (Phase II) • Distribution of functional elements to TSG-groups • Radio resource management • Mobility management • Support of legacy signaling with sigtran, megaco, etc. • Leverage expertise of individual groups
