Embodiment 1

[0043] Embodiment 1: In this embodiment, after receiving the random access request, the BTS first judges whether the random access request is an abnormal random access request, and if so, discards the request directly, otherwise reports the request to the BSC so that the BSC SDCCH is assigned to the requesting entity.

[0044] figure 2 It is a flow chart of the random access request control method in Embodiment 1 of the present invention, wherein a storage unit for storing RA is added to the BTS, and the first random access request received by the BTS through parsing is pre-stored in the storage unit As for the learned RA, specifically, the BTS pre-stores the RA carried in the first received CH_REQ message.

[0045] At the same time, the random access request control method in this embodiment is the random access request control method adopted by the BTS when processing the received random access requests of the second and subsequent items. The random access request in this ...

Embodiment 2

[0052] Embodiment 2: In this embodiment, the BTS directly reports to the BSC after receiving the random access request, and the BSC judges whether the random access request is an abnormal random access request, and if so, directly discards the request, otherwise the BSC The SDCCH is assigned directly to the requesting entity.

[0053] image 3 It is a flow chart of the random access request control method according to Embodiment 2 of the present invention, wherein at least one storage unit corresponding to at least one BTS under the jurisdiction of the BSC is added to the BSC, and each storage unit is used to store the BSC corresponding to the BSC through parsing. The RA obtained from the first random access request reported by the BTS, specifically, each storage unit pre-stores the RA obtained by parsing the first CH_RQD message corresponding to the BTS.

[0054] At the same time, the random access request control method in this embodiment is a random access request control ...

Abstract

The method saves random access (RA) value carried by previous piece of random access request. The method includes steps: (1) receiving current RA request, determining whether RA carried by current RArequest is identical to the saved RA; if yes, then, discarding the current RA request, and ending the flow, otherwise executing step (2); (2) assigning special dedicated control channel SDCCH to entity of sending current RA access request. The invention solves issue that it is difficult for mobile station to access network cause by large numbers of abnormal RA access request in current technique.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a random access request control method. Background technique [0002] According to the current integrated mobile communication system (GSM) protocol, in any case, if the mobile station (MS) needs to access the GSM network, it should first send a random access request to the base station subsystem (BSS) to apply for an independent dedicated control channel ( SDCCH). Correspondingly, after receiving the random access request, the BSS executes an assignment process to assign the SDCCH to the MS. [0003] figure 1 It is a flowchart of an existing random access request control method, and the existing random access request control method includes: [0004] Steps 101-102: The base station (BTS) analyzes the channel request (CH_REQ) message sent by the MS through the random access channel (RACH), and learns the random access value (RA) carried in the current CH_REQ message...
