Problems solved by technology

This makes the access process of the mobile station only serial, not parallel, so it is slow to assign service information to the mobile station, especially when the MSC load is heavy, it will cause the mobile station to time out and cause the call to fail
The general solution to the above problem is to add a switch network between the selector and the vocoder, or between the vocoder and the EI trunk line, so as to ensure that the selector allocated first can be used no matter which vocoder module is located. Switch to any EI trunk circuit through the switching network, but this method greatly increases the cost of the base station

Embodiment Construction

[0017] refer to figure 1 , the workflow of selector switching in the present invention (taking the occurrence of a switching as an example) is as follows:

[0018] a. After receiving the initial call message or paging response message of the mobile station, the base station controller (hereinafter referred to as BSC) considers that resources need to be allocated, establishes a call connection, and sends Abis-BTS Setup to the base transceiver station (hereinafter referred to as BTS) Message, which contains the allocated traffic channel resource information and selector address (SDU ID), which is a selector of a selector module randomly selected by the BSC (hereinafter referred to as SDU);

[0019] b. After receiving the Abis-BTS Setup message, the BTS sends an Abis-Connect message to the selector module according to the address of the SDU. The message carries the allocated service channel resource information and service information;

[0020] c. The selector module creates a ...

Abstract

A selector switching method of base station in CDMA system for speeding up the access process of mobile station includes receiving the access request from mobile station, randomly choosing a source selector and asigning it to the mobile station, receiving the asign request of MSC, judging the target selector module which should be used, comparing the source selector module with target selector module, and switching to target selector module if they are not matched.

Description

technical field [0001] The invention belongs to the technical field of wireless mobile communication, and is suitable for accelerating the completion of the access process of the mobile station and entering the communication state in the CDMA (Code Division Multiple Access) cellular wireless communication system. Background technique [0002] In the Code Division Multiple Access (hereinafter referred to as CDMA) mobile communication system, when the mobile station needs to talk, it connects to the mobile communication network through the base station, and the base station allocates traffic channel resources and selector resources necessary for traffic channel work to the mobile station. Since the selector is generally located in the vocoder module, and the vocoder module corresponds to the trunk EI circuit connected to the mobile exchange (hereinafter referred to as MSC), so the base station often has to wait until the MSC sends an assignment request message to determine the ...
