Optimized access method for mobile terminal quitting Idle mode

Abstract

The invention provides an optimized accessing method for a mobile terminal exiting Idle mode, comprising steps of: step 1, when the mobile terminal enters Idle mode, a base station entering the Idle mode will carry the base station ID to a paging controller for storage; step 2, when the mobile terminal exits the Idle mode, a service base station exiting the Idle mode asks the paging controller for context information of the mobile terminal; step 3, the paging controller returns a first information to the re-entering base station; wherein, the first information carries the context information of the mobile terminal and the base station ID stored when entering the Idle mode; step 4, when exiting the Idle mode, the service base station obtains the station ID stored when entering the Idle mode from the paging controller, and compares with itself ID for successive processing according to the comparative result.

Description

technical field [0001] The present invention relates to the communication field, and in particular relates to an optimized access method for a mobile terminal exiting an idle (Idle) mode in WiMAX (Worldwide Interoperability for Microwave Access). Background technique [0002] Currently, the air interface protocol IEEE802.16e of the broadband wireless access system supports an Idle function of a mobile terminal (Mobile Station, MS), which is a power saving mode of the MS when there is no data transmission. [0003] In Idle mode, the base station will release the relevant information of the MS. In order to enable the MS to quickly re-enter the network when the MS exits the Idle mode, when the MS enters the Idle mode, the base station will release a large amount of context information of the MS (including capability negotiation context, registration context, security context, etc.) are stored in the paging controller (Paging Controller, PC) and the location register (Location R...

Problems solved by technology

[0004] However, the IM Exit MS State Change Response in the current R6 message does not contain the base station ID (Base Station ID,) when the MS enters the Idle mode. When paging the context of the MS on the Paging Controller (PC), it is necessary to compare the capabilities in the context of the MS with the capabilities of the base station side to determine whether the capabilities of the two are consistent, and then notify the MS to perform an access optimization process, However, this comparison is relatively cumbersome.

[0005] In reality, there are a large number of situations where MS enters and exits Idle mode under the same BS. For example, a certain terminal moves in a small area for a long time (for example, office scene), but due to the cumbersome comparison in the current processing flow Processing, so the processing speed of BS is very slow and not efficient
