IP Cloud Mobile WiMAX – ASN Variants BS BS Anchor Router / Gateway IP Cloud BS + Router BS + Router To CSN To CSN Mobility Management Requirements: Must accommodate Flat and Hierarchical ASN topologies – and variants thereof Must support multi-hop relay among BSs Must support multi-path configurations among BSs Eliminate need for signaling from client to ASN for intra/inter ASN MM Ideal scenario is network-based MM both within/across ASN and end-to-end Must work irrespective of client connectivity state – Active, Idle Client IP reachability in all power states with configurable location anonymity IPv4 and IPv6 Eliminate / reduce need to simulcast within ASN for duration of HO – prevent backhaul BW wastage especially for wireless backhaul ASN |
