Problems solved by technology

[0013] In practical application, the above-mentioned solution has the following problems: the listeners of the voice group call service (Voice Group Call Service, referred to as "VGCS") / voice broadcast service (Voice Broadcast Service, referred to as "VBS") cannot pass the switching To achieve real-time channel adjustment, the congestion rate will increase in areas or periods of high VGCS / VBS call traffic. In addition, when there is a margin in network channel resources, it is impossible to improve the VGCS / VBS business using half-rate group call channels. voice quality
[0014] The main reason for this situation is that for the VGCS / VBS call service, the network side cannot adjust the channel in real time through switching, so the channel used by the listener of the VGCS / VBS call cannot be reclaimed. On the one hand, it may lead to the inability to access full-rate services, which will lead to an increase in congestion rate; on the other hand, even if there is a margin of channel resources, it will not be possible to transfer traffic on the VGCS / VBS half-rate channel. The listener adjusts to the full-rate channel, which cannot improve the voice quality of VGCS / VBS in real time

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The scheme of the present invention uses channel release (CHANNEL RELEASE ) message to instruct the listener of VGCS / VBS call to release the old channel and transfer to the new channel indicated by the CHANNEL RELEASE message to continue the service when the channel of the VGCS / VBS call needs to be adjusted in real time, and then the network The side recovers the old channel to realize real-time adjustment of the channel of the VGCS / VBS call.

[0036] In order to better illustrate the solution of the present invention, the following will be described in conjunction with the implementation manners of the present invention.

[0037] The flow of the method for real-time channel adjustment in GSM according to the first embodiment of the present invention is as ...

Abstract

The invention is used for real-time adjusting the voice group call service (VGCS) / voice broadcast service (VBS) channel. In the invention, when group call channel needs to be adjusted, the new group call channel is enabled for VGCS / VBS users, and the channel releasing message carrying new group call description is sent down in the adjusted old group call channel; informing those VGCS / VBS listenerto transfer to the new group call channel; recovering the old group call channel. If the old group call channel is still occupied by VGCS / VBS talker, then firstly transferring the VGCS / VBS talker to the new channel, and secondly transferring the VGCS / VBS listener to the new channel.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the adjustment technology of a group call channel. Background technique [0002] The Global System for Mobile communication ("GSM") was designed by a standardization committee composed of major European telecom operators and manufacturers, developed on the basis of cellular systems, and is the world's first digital modulation , Network layer structure and services are specified in the cellular system. [0003] The GSM system architecture mainly includes Base Station Subsystem (BSS for short), Network and Switching Subsystem (NSS for short), and Operational Support System (OSS for short). and a mobile station (MobileStation, referred to as "MS"). Among them, BSS is a network composed of wireless cells, including base transceiver station (Base Transceiver Station, referred to as "BTS") and base station controller (Base Station Controller, referred to as "BSC"), a BSC can contr...
