Patent ID: 8229475

Claim:
A method for improving performance of mobile broadband wireless access system, comprising: Step 1, a paging controller controlling a base station to send a Mobile Paging Advertisement message (MOB-PAG-ADV message) to a mobile station; the mobile station responding to the paging controller through the base station which responses to the mobile station; Step 2, the paging controller sending a paging notice message to inform base stations in paging group that do not respond to the mobile station to stop sending the MOB-PAG-ADV message; Step 3, after receiving the paging notice message sent by the paging controller, the base stations in the paging group that do not respond to the mobile station instantly stopping sending the MOB-PAG-ADV message to the mobile station and deleting corresponding data; wherein said step 1 comprises: Step a, when a network needing to start up a paging process, the paging controller to which the mobile station in idle mode belongs constructing the paging notice message, which indicates purpose of the paging and starting the paging, the paging controller sending the paging notice message to all the base stations in the paging group associated with the mobile station; Step b, after receiving the paging notice message from the paging controller, the base station constructing and sending the MOB-PAG-ADV message to the mobile station; Step c, the mobile station sending a Ranging Request message (RNG-REQ message) to the base station according to the instruction in the MOB-PAG-ADV message; Step d, if the base station which has received the RNG-REQ message has validity check information, performing validity check; Step e, if the validity check is passed, the base station which has received the RNG-REQ message notifying the paging controller which manages the mobile station that an access response from the mobile station has been received successfully; if the validity check is not passed, the base station which has received the RNG-REQ message discarding the RNG-REQ message, continuing to send the MOB-PAG-ADV message and waiting for the response from the mobile station; or the base station stopping sending the MOB-PAG-ADV message and immediately starting a complete process of re-access to the network.
