21-07-0205-02-0000 Overview IEEE P802.21/D05.00 specifies handover procedures in the Annex A. A.1 Mobile-initiated handover procedure A.2 Network-initiated handover procedure A.3 Network-initiated handover from 802.16 to 3G (Single PoS) A.4 Handover from 3G to WLAN A.5 Example handover flow chart between 802.11 and 802.16 A.6 Example handover flow charts for Mobile IP A.7 Handover flow diagram for abnormal cases

21-07-0205-02-0000 Problems Statement Protocol message naming inconsistency with the normative part. Use of obsolete MIH_Switch. Different assumption about the relationship MIH primitive and lower layer connection setup or higher layer execution. Relationship between MIH_Net(MN)_HO_Commit and L2 connection setup. Relationship between MIH_MIH_MN_HO_Complete and higher layer handover execution. Related contributions 21-07-0110-01-0000-HO_SignallingDiagrams (A2, A3, A4.1, A4.2) 21-07-0181-00-0000-Optimization about A.4.1 and A.4.2 (A4.1, A4.2)

21-07-0205-02-0000 Resolution Guideline Follow the protocol name as defined in the normative section. With the form of MIH_Net_HO_Candidate_Query “Request” Four Steps Step 1. Resource Availability Check MIH_(MN)Net_HO_Candiate_Query MIH_N2N_HO_Candidate_Query Step 2. Resource Preparation MIH_N2N_HO_Commit Step 3. Handover Commitment MIH_(MN)Net_HO_Commit MIH_Configure_Link Step 4. Resource Release MIH_MN_HO_Complete MIH_N2N_HO_Complete
