Embodiment Construction

[0035] The embodiment of the invention provides a method and device for transmitting data service and voice service in GSM. In the embodiment of the present invention, a data transmission channel is set in a GSM service channel; GSM users transmit data services through the data transmission channel.

[0036] The following describes the embodiment of the present invention in detail in conjunction with the accompanying drawings. The processing flow of the method described in the embodiment of the present invention is as follows figure 1 shown, including the following steps:

[0037] Step 1-1: Divide the frame structure of TCH / FS and TCH / HS into two parts: SubChannel0 and SubChannel1.

[0038] The frame structure of TCH / FS and TCH / HS defined in the GSM standard is as follows figure 2 As shown, it consists of 26 TDMA (Time Division Multiple Access, Time Division Multiple Access) frames, wherein the 12th frame is used to transmit a frame accompanying the signaling channel, and t...

Abstract

The invention relates to a method and device for transmitting data services and voice services in GSM (Global Communications System for Mobile Communications). The method mainly includes: setting a data transmission channel in a GSM service channel; data business. The device mainly includes: a channel setting module: used for setting a data transmission channel in a GSM service channel, and GSM users can transmit data services through the data transmission channel. Utilizing the method and device of the invention, it is possible to transmit data services while transmitting voice calls in GSM.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for transmitting data services and voice services in GSM. Background technique [0002] GSM (Globe System of Mobile Communication) is a typical TDMA (Time Division Multiple Access) wireless communication system, which defines TCH / FS (Full rate SpeechTraffic Channel) in the standard GSM protocol , full rate voice traffic channel) and TCH / HS (Half rate SpeechTraffic Channel, half rate voice traffic channel) two basic voice traffic channel coding methods. [0003] Both the above TCH / FS and TCH / HS are mainly used to transmit voice, and the channel-associated signaling channels in TCH / FS and TCH / HS can transmit some simple control signaling. The above-mentioned TCH / FS and TCH / HS cannot transmit a large amount of data services simultaneously during a voice call. Contents of the invention [0004] The purpose of the embodiments of the present invention is to ...
