Patent ID: 8078199

Claim:
An implementation method for accelerating paging access of a mobile station in broadband wireless system, comprising the following steps: (a) when an Anchor access service network gateway (ASN-GW) finds out that a mobile station(MS) is in an Idle mode when the Anchor access service network gateway receives downlink data addressed to the mobile station, the Anchor access service network gateway notifying an Anchor paging controller to which the mobile station belongs to page the mobile station, and when the Anchor paging controller finds out that the mobile station is authenticated with paging operation, the Anchor paging controller sending a Paging Announce message including at least mobile station identifier (MSID) and Authenticator identifier of the mobile station, to part of or all base stations in a paging group via other Relay paging controller or directly; (b) said base stations keeping corresponding relationship between the Authenticator identifier and the mobile station after the base stations receives the message, and sending a MOB-PAG-ADV message of an air interface to the mobile station; (c) after the mobile station receives the MOB-PAG-ADV message addressed to the mobile station itself, the mobile station starting a process of paging access, the mobile station sending a RNG-REQ message to the base station after the mobile station completes uplink synchronization, and then after the base station receives the RNG-REQ message returned by the mobile station, the base station interacting with an authenticator with an Authenticator identifier parameter corresponding to the mobile station to obtain an authentication key (AK) and authenticating the RNG-REQ message; and the base station obtaining associated information of said mobile station from the Anchor paging controller while the base station interacts with the authenticator; (d) said base station requesting the Anchor access service network gateway to establish a data channel, and before or after the data channel is established, the base station sending a RNG-RES message to the mobile station; and (e) after the mobile station completes network access, the base station sending a Data Channel Establishment Acknowledgement message to the Anchor access service network gateway, and after the Anchor access service network gateway receives the Data Channel Establishment Acknowledgement message sent by the base station, the Anchor access service network gateway sending a MS Info Release Announce message to the Anchor paging controller to notify the Anchor paging controller to delete the information saved thereon by the mobile station.
