Step 405, terminal implement the registration of 802.16e network;
Step 406, ASN-GW (Access Service Network Gateway, access service network gateway) is initiated to the registration of the data channel of WiMAX BS;
Step 407, WiMAX BS is accomplished to the foundation of terminal initial Business Stream and/or pre-provisioned service flow;
Step 408, terminal are sent dhcp discover message to ASN-GW, are used to find that Dynamic Host Configuration Protocol server is to carry out the host ip configuration;
Step 409, the MAG among the ASN-GW triggers the PMIP registration process.The NAI that carries in the agent binding update messages will be consistent with the NAI that uses in the EAP access authentication process; Switch the indication option simultaneously and be set to 2 (Handoff between two different interfaces; Represent to switch between different access styles); The access technology type option is set to 5 (be IEEE 802.16e, expression WIMAX inserts);
Step 410 after HA/LMA receives agent binding update messages, is terminal to apply IP address; Judge that simultaneously switching the indication option networks for switching; Then do not send to AAA and upgrade the HA/LMA address message, HA/LMA sends proxy binding acknowledgment messages to ASN-GW, carries the IP address into terminal to apply;
Step 411 is set up the PMIP tunnel between HA/LMA and the ASN-GW;
Step 412, the DHCP proxy among the ASN-GW returns DHCP to the terminal and gives information, and carries the IP address into terminal to apply;
Step 413, the DHCP request message is sent to ASN-GW in the terminal, carries the IP address of from DHCP gives information, receiving;
Step 414, ASN-GW returns the DHCP acknowledge message to the terminal, confirms the use of this IP address and carries other configuration parameters to the terminal;
Step 415, the terminal successful switch also is connected to the WiMAX access service network, can be through the up/downlink data of WiMAX access service network transmission;
Step 416, the connection and the resource of release WiFi network behind the handover success.
During conversation end; When HA/LMA receives agent binding update messages (Proxy Binding Update, be called for short PBU), wherein Lifetime represented that unbind upgraded at 0 o'clock; Then HA/LMA sends and upgrades HA/LMA message to AAA/HSS, removes the HA/LMA address information of recording user current sessions.
