Embodiment 1

[0061] Such as image 3 As shown, the terminal location update process of this embodiment mainly includes the following steps:

[0062] Step 1: The terminal sends an RNG-REQ message to the base station to request location update and bring CMAC_KEY_COUNT M ;

[0063] Step 2: After receiving the RNG-REQ message of the terminal, the base station sends an LU_Req message to the AGW to request location update;

[0064] Step 3: AGW replies LU_Rsp to the base station with CMAC_KEY_COUNT N ;

[0065] Step 4: The base station receives the LU_Rsp message and sets CMAC_KEY_COUNT B Set to CMAC_KEY_COUNT N , Perform message authentication on RNG-REQ and the message authentication is successful, reply to the successful RNG-RSP, buffer the successful RNG-RSP message, and start the resource reservation timer TLURemain;

[0066] Among them, the timing period of the resource reservation timer should be greater than the timeout period for the terminal to retransmit the RNG-REQ.

[0067] In this embodiment, ...

Embodiment 2

[0076] Such as Figure 4 As shown, the terminal location update process of this embodiment mainly includes the following steps:

[0077] Step 1: The terminal sends an RNG-REQ message to the base station to request location update and bring CMAC_KEY_COUNT M ;

[0078] Step 2: After receiving the RNG-REQ message of the terminal, the base station sends an LU_Req message to the AGW to request location update;

[0079] Step 3: AGW replies LU_Rsp to the base station with CMAC_KEY_COUNT N ;

[0080] Step 4: The base station receives the LU_Rsp message and sets CMAC_KEY_COUNT B Set to CMAC_KEY_COUNT N , Perform message authentication on RNG-REQ and the message authentication is successful, reply to the successful RNG-RSP, buffer the successful RNG-RSP message, and start the resource reservation timer TLURemain;

[0081] In this embodiment, the RNG-RSP message replied by the base station is lost at this time;

[0082] Step 5: In the timing period of TLURemain, the base station receives the RNG-RE...

Abstract

Disclosed are a method and an apparatus for location update. The method includes: after successfully authenticating a ranging request (RNG-REQ) message initiated by a terminal, a base station replies a success ranging response (RNG-RSP) message, and buffers the RNG-RSP message; when receiving the RNG-REQ message retransmitted from the terminal in a preset time, the base station retransmits the buffered RNG-RSP message to the terminal. By buffering the RNG-RSP message replied to the terminal, and retransmitting the buffered RNG-RSP message to the terminal when receiving the RNG-REQ message retransmitted from the terminal, the present avoids that the terminal initiates to exit an IDLE mode re-entry procedure when the terminal does not receive the RNG-RSP message, thereby enhancing the success rate of location update for the terminal and improving the user experience.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and more specifically, to a location update method and device. Background technique [0002] WiMAX (World Interoperability for Microwave Access) is a broadband wireless access metropolitan area network technology based on the IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.16 standard. Its basic goal is to access the metropolitan area network. Ensure that wireless devices from different manufacturers are interconnected. WiMAX is mainly used to provide "last mile" high-speed broadband access for homes, businesses and mobile communication networks, as well as personal mobile communication services in the future. The IEEE802.16 standard formulated the physical layer (PHY) and media access layer (MAC) specifications IEEE802.16e, referred to as 16e. This specification adds support for mobility on the basis of IEEE802.1...
