Overall Inter-RAT Handover Steps Network Discovery Available Networks Intersystem Mobility Policy Inter-RAT Measurement SIBs acquisition for other RATs Measurement configuration and report Handover Execution May perform pre- registration Packet rerouting 21-10-0221-00-srho3
3GPP Optimized Single Radio Handover for 3GPP2 Dual-Radio Handover for WiMAX 21-10-0221-00-srho4
3GPP Tight coupling for 3GPP2 networks 3GPP eNBs transfer SIBs of 3GPP2 using RRC messages for measurement configuration ANDSF Utilizes OMA Device Management (DM) protocol for communication with UEs Mobility Policy and Discovery Information Intersystem mobility policy priorities the access network Discovery Information provide further information for the UE to access the access network defined in the policy WiMAX Network Discovery and Selection (WNDS) MO FrequencyInfo, NAP-I, CellType, OperatorDifferentiatedTextField FrequencyInfo: FirstFreq, LastFreq, NextFreqStep, ChannelBandwidth, DuplexMode, FFT_Size, Preambles 21-10-0221-00-srho5
WiMAX NWG WiMAX-3GPP EPC IWK Currently active for 3GPP Rel9-PCC WiFi- WiMAX IWK ND&S is enabled by 802.21 Information Service Bi-directional between WiFi and WiMAX Non- WiMAX to WiMAX Handover SRHO Optimization (Pseudo Modes) Focus on handovers toward WiMAX 21-10-0221-00-srho6
WiMAX TWG 21-10-0221-00-srho7 802.16-2009 - Recent IoPR for Direct Inter RAT Advertising (withdrawn) 802.16m - On-going decision for profiling. Inter-RAT HO support using other RAT's message using L2 transfer message. Inter-RAT HO support using the MIH frame (802.21)
MIH support in 802.16 Distinctive MIH MAC container PKM, SII-Adv for MIH query and response 802.16- 2009 Generic L2- Xfer: MIH type, ORAT type PKM, SII-Adv for MIH query and response 802.16m 21-10-0221-00-srho8
Discussion Strength Uniform container for various IWK cases Both L3 and L2 support Cross-layer optimization Dynamic information exchanges: CS, ES Weakness. Mobility Policy (out of scope) 21-10-0221-00-srho9
