Mobility Management IMS IPTV Resource Managemnt Web en.! Session Handling IP Multimedia Subsystem (SIP based) GMM Operator Core Network! Macro Mobility GMM (Mobile IPv6) LMM AD LMM AD LMM AD! Micro Mobility LMM - Distributed in Domain (IPRM functionality)
IPRM Fundamental Concept (I) Network Convergence based on IPRM User Plane Packet Forwarding Dynamic configuration Plane Resource and Mobility Mgmt. on Network Layer (IPRM) User + Service Specific technology agnostic Agnostic Metric Any Link/Phy Layer (Ethernet, DSL, ATM, UMTS (Uu), WiMAX, )
IPRM Fundamental Concept (II) xdsl PON MTE Domain LMM Aggregation! Terminal becomes moving network! TE-Engineered tunnel becomes one hop! Wireless access link becomes one hop! Wireline access link (xdsl/pon/eth) becomes one hop! Service / User specific metrics per hop! Routing protocols used for metrics distribution! TE algorithms exploit metrics for forwarding decisions! Full integration of multi-interface terminals! multi-path routing

IPRM - Examples Aggregation IPRM is open for more concepts like! load sharing via different mobile interfaces! (Network) MIMO concepts are feasible! Efficient personal mobility! Smooth integration of multi-hop and ad-hoc networks! New deployment scenarios (e.g. UMTS at home)
Efficient Routing IPRM allows efficient routing between communicating terminals connected to... IMS IPTV Resource Managemnt Web en.! Same Unified! Same Domain GMM Operator Core Network! Different Domains AD AD AD Concepts holds for any access technology!
Migration Issues... Seamless service continuity for a moving legacy mobile is required! Operator Core Network Three Aspects: (a) Interworking between UMTS Network ans Domain (b) Interworking between legacy mobile and UMTS Network (a) Domain (c) Mapping of legacy mobile into IPRM architecture (c) (b)
Summary and Outlook Summary:! Application vs. network convergence! Architecture build upon the ideas of IPRM Unified resource and mobility management Efficient routing! Migration path essential part of concept Lucent focus in ScaleNet project:! Design of efficient routing protocols and algorithms to support IPRM ( plane handling within Domain)! Efficient Transport of user traffic (User plane handling within Domain)! ScaleNet Demonstrator
