Case 1: MN initiated handover This case is derived from the example in section G.5 of the IEEE 802.21 Draft 6.0. The MN is connected to the IEEE 802.11 network and is attached to PoS1 The MN moves away from the AP and a Link Going Down is generated to indicate the start of the handover process: The MN scans for IEEE 802.16 networks The MN checks for resource availability and performs resource reservation MN performs traffic redirection upon receiving an MIH_MN_HO_COMMIT.confirm If any MIH message is lost, the MN receives a Link Down from the 802.11 interface and performs traffic redirection. |
