Case 2: Network initiated handover The scenario is derived from the example in section G.2 of the IEEE 802.21 Draft 6.0. The MN is connected to the IEEE 802.11 network and is attached to PoS1 The serving PoS1 receives indications that the MN is leaving the cell (local or remote Link Going Down): PoS1 initiates the Resource availability check The MN scans for IEEE 802.16 networks and reports to PoS1 PoS1 performs network selection and indicates its choice of target network to the MN MN performs traffic redirection upon receiving an MIH_Net_HO_COMMIT request If any MIH message is lost, the MN receives a Link Down from the 802.11 interface and performs traffic redirection. |
