Abstract

An implementation method and system for accelerating the paging access of a mobile station in broadband wireless system are disclosed, and this system comprises base stations, mobile stations, an anchor access network gateway, an authenticator and a paging controller. The implementation method includes: (a) the anchor access network gateway sends to the base station a Paging Announce message including at least mobile station identifier and the authenticator identifier of the mobile station; (b) the base station keeps the corresponding relationship of the authenticator identifier and the mobile station, and sends a MOS-PAG-ADV message to the mobile station; (c) after the base station receives the RNG-REQ message from the mobile station, it interacts with the authenticator using the authenticator identifier to obtain the authentication key and perform the authentication; and acquire the information of mobile station from the paging controller; (d) before or after the base station requests the anchor access network gateway to establish a data channel, it sends a RNG-RES message to the mobile station; (e) after the anchor access network gateway receives the Data Channel Establishment Acknowledgement message, it informs the paging controller to delete the mobile station information thereon. The present invention can accelerate the process of paging access of the mobile station.

Dependent claims

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.

4 more elements

A system for accelerating paging access of a mobile station in broadband wireless system, comprising one or more base stations, a mobile station, an anchor access network gateway, an authenticator, and a paging controller, characterized in that:

said Anchor access service network gateway is configured to:
after receiving downlink data addressed to the mobile station, sends a MS Info Request message to the paging controller which the mobile station belongs to and receives the MS Info Response message sent back from the paging controller;
after receiving a Data Channel Establishment Request message sent by the base station, sends a Data Channel Establishment Response message to the base station;
and after receiving a Data Channel Establishment Acknowledgement message sent by the base station, send a MS Info Release Announce message to the paging controller;
said paging controller is configured to send a Paging Announce message including at least mobile station identifier and authenticator identifier of the mobile station to the base stations;
and after receiving the MS Info Release Announce message sent by the Anchor access service network gateway, delete the information saved thereon by the mobile station;
said base station is configured to:
after receiving the Paging Announce message sent by the paging controller, keep corresponding relationship of the authenticator identifier of the mobile station and mobile station, and send a MOB-PAG-ADV message to the mobile station;
after receiving a RNG-REQ message returned by the mobile station, interact with the authenticator through the mobile station identifier corresponding to the mobile station to obtain an authentication key and authenticate the RNG-REQ message;
while interacting with the authenticator, send the MS Info Request message to the paging controller and receive the MS Info Response message sent by the paging controller;
and send the Data Channel Establishment Request message to the Anchor access service network gateway, and before or after receiving the Data Channel Establishment Response message sent by the Anchor access service network gateway, send the RNG-RES message to the mobile station;
said mobile station is configured to, after receiving the MOB-PAG-ADV message sent by the base station for addressing the mobile station itself, send the RNG-REQ message to all base stations and receives the RNG-RES message from all base stations;
said authenticator is configured to interact with the authenticator identifier parameters corresponding to the mobile station to obtain the authentication key and send the authentication key to the base station.
