As shown in Figure 2, the flow process of terminal initial access 3GPP Pre-R8 network may further comprise the steps:
Step 201, MS sends Attach Request message to SGSN, has the IMSI of MS in the message;
Step 202, SGSN and HLR/HSS are alternately to carry out authentication to MS;
Step 203, SGSN executing location renewal process is also obtained user data from HSS;
Step 204, after the authentication success, SGSN returns to adhere to MS and accepts message;
Step 205, MS sends to SGSN and activates the PDP Context request message, wherein carries information such as intercommunication special-purpose APN, PCO, and SGSN parses the IP address of corresponding IWK according to the special-purpose APN of intercommunication;
Step 206, SGSN sends to corresponding IWK and creates the PDP Context request message;
Step 207 is initiated IP CAN session and is set up process, with the PCC corresponding strategies information of download user between PCEF under the IWK and PCRF;
Step 208, IWK sends to HSS/HLR and upgrades the IWK address message, notice HSS/HLR buffer memory IWK address; So that switch the objective network that again address is returned to switching in the network re-entry authentication process at the across a network of terminal, so that anchoring to the IWK at former session place when across a network switches, terminal reserves to realize the address, thus the continuity of assurance Packet Service;
Step 209, IWK responds to SGSN and creates the PDP Context response message, and wherein carrying IWK is the MS IP address allocated;

Step 307, ASN-GW gives information the HoA address and sends to UE by DHCP;
Step 308 after UE receives that DHCP gives information, sends the DHCP request message, accepts the HoA address of distribution, and asks other IP configuration parameters;
Step 309, after ASN-GW received the DHCP request message, the relevant IP configuration parameter that UE is asked returned to UE by the DHCP acknowledge message;
Step 310 is initiated IP CAN session and is set up process, the PCC corresponding strategies information of download user between the PCEF at ASN-GW place and the PCRF;
Step 311, ASN-GW carries out the modification of initial service flow/pre-provisioned service flow and/or the establishment of pre-provisioned service flow according to the PCC configuration information;
Step 312, follow-up data will transmit by the WiMAX network.
