Embodiment 1

[0062] When the SBS receives the location update request RNG REQ message from the MSS, the SBS does not authenticate the message, but sends the location update request message LU REQ / MSS INFO REQ to the APC / LR. The message carries the complete RNG REQ received by the SBS Message (message body and message authentication code). After receiving the message, APC / LR first uses the key derived from AK to authenticate the RNG REQ message carried in the message. After passing the authentication, it constructs the RNG RSP message (message body and message verification code), and then updates the relevant information of the AK context. Specifically, the only context information that may be updated is CMAC_PN_D and CMAC_PN_U, and a location update request message LU RSP / MSS INFO RSP is sent to the SBS, which carries a complete RNG RSP message. After receiving the message, the SBS parses out the RNG RSP and sends it to the MSS to continue the subsequent location update process.

Embodiment 2

[0074] When the SBS receives the location update request RNG REQ message from the MSS, the SBS does not authenticate the message, but sends the AK REQ message to the APC / LR. In addition to the information required to request the AK key, the message also carries the The complete RNG REQ message (message body and message verification code) received by SBS. After receiving the AK REQ message, the APC / LR first uses the AK-derived key to authenticate the RNG REQ message carried in the message. After the authentication passes, it updates the relevant information of the AK context and sends the AK TRA message to the SBS. The message carries the The corresponding effective AK. After receiving the message, the SBS continues the subsequent location update process.

Embodiment 3

[0086] When the SBS receives the location update air interface request RNG REQ message from the MSS, when the MSS performs location update on a base station for the first time, and there is no valid AK corresponding to the MSS on the SBS, it sends an AK to the APC / LR REQ message, after receiving the message, APC / LR sends AK and its context information to SBS through AK TRA message, and SBS can use the key and serial number information in AK and its context information to authenticate the RNG REQ message and judge Whether the message is a replay message. After the message is authenticated and determined not to be a replay message, the SBS updates the AK context information, and uses the subsequent network-side location update message to notify the APC / LR of the updated AK context-related information. After the first interaction, there is a corresponding AK on the BS.

Abstract

This invention provides control methods for refreshing positions, 1, the certification to the required information of position refreshment and the refreshment to the context information of an authority authenticated cryptographic key are finished on a bp controller as well as the generation of vacancy information of the refreshed response and SBS only delivers information in the process of interaction of the position refreshed information, 2, the certification of the refreshed information is done on SBS and then the authority authenticated cryptographic key context information is delivered to the bp controller to ensure the position refreshing can be carried out safely next time.

Description

technical field [0001] The invention relates to mobile communication technology, and particularly discloses a control method for updating the position of a mobile terminal in an idle state. Background technique [0002] The idle mode is a terminal working mode in the mobile broadband wireless access system defined by the IEEE 802.16e standard. In idle mode, MSS (Mobile Subscribe Station, mobile subscriber) can move in a large area, receive downlink broadcast service messages every certain period, and notify MSS through broadcast messages whether there is downlink service to send, and MSS is in this area During the intra-roaming process, it is not necessary to register with the BS (Base Station, base station) of the roaming cell. At the same time, when the MSS roams to different cells, it does not need to perform normal operation procedures such as handover, which helps to save MSS power and air interface resources. [0003] Multiple BSs can form a group, called a paging gr...
