Problems solved by technology

[0007] However, this method cannot avoid the "ping-pong effect" generated by the terminal during the mobile process, that is, the terminal returns again after leaving the paging area to which a certain base station belongs. At this time, the base station has deleted the reserved security context information of the terminal. Therefore, it is necessary to request the security context information of the terminal from the paging controller or authenticator (Authenticator) on the network side again

Embodiment Construction

[0023] An existing 802.16e system paging area division and idle mode terminal mobile process is shown in Figure 1 . 1 and 2 are base stations, 3 is a terminal, 5 and 6 are paging areas where base stations 1 and 2 are located, and 4 is a moving route of a terminal in idle mode. The first and second location updates occur between the terminal and base station 1, then the terminal may leave the paging area where base station 1 is located and enter the paging area where base station 2 is located, and complete the third location update with base station 2, Then the terminal enters the paging area where the base station 1 is located again, and completes the fourth location update process with the base station 1 .

[0024] The existing 802.16e system idle mode location update process is shown in Figure 2. The terminal first sends a ranging request message (RNG-REQ) to base station 1 to request location update, and base station 1 sends a location update request message to the paging c...

Abstract

The present invention discloses a method for the location update of the idle mode, relating to the arrangement used for the mobile service area's coverage. It responses to the problem of the base station and the network side's message interactive increase that resulted from the 'ping-pong effect' which the existing technology aroused. The present invention comprises setting a timer for the base station. When the base station receives the corresponded security context messages, it catches these messages and set a corresponded timer. When the time comes to end, the message that the base station cached is deleted. The present invention can avoid the useless message interactive between the base station and the local paging controller, and it can save the news-bandwidth. At the same time, it accelerates the process of the location update for avoiding the 'ping-pong effect'.

Description

technical field [0001] The invention relates to an arrangement for mobile service area coverage, in particular to a location update method in an idle mode. Background technique [0002] The 802.16e standard is a fixed and mobile broadband wireless access standard formulated by the IEEE standard organization. Compared with the 802.16d standard, due to the increased support for mobility, it is necessary to adopt some technologies that can save power for the terminal, such as: sleep mode (Sleep mode) Mode) and idle mode (Idle Mode), wherein the idle mode can save the energy consumption of the terminal more than the sleep mode, and increase its standby and use time. After entering the idle mode, the terminal only periodically receives downlink broadcast data (including paging messages and broadcast and multicast services) at discrete intervals, and does not need to perform handover or network reconfiguration when moving across multiple base stations. Access process. [0003] I...
