Problems solved by technology

[0009] However, in the wireless communication system with group call function based on GSM technology at present, it has not yet realized the simultaneous transmission of short data during the speaking process, that is, data and voice simultaneous interpretation
As a result, it is impossible to realize services that require data and voice simultaneous interpretation, such as plane shunting

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] First of all, it should be explained that the wireless communication system referred to in the present invention is a system with wireless group call function based on the GSM system, including GSM-R and GT800 systems. The present invention can be applied to plane shunting business, therefore, the short data can be safety data for plane shunting.

[0036] Specifically, on the GSM-R platform, since users within a group share channels, if simultaneous interpretation of data and voice is to be implemented, user behavior needs to be divided into speaker cells and non-speaker cells. GSM has multiple time slots. For a physical cell, each time slot can construct a speaker cell. In the non-speaker cell, the uplink is idle and short data can be sent. In the speaker...

Abstract

The present invention discloses group calling short data transmission method relating to group calling wireless communication technology, to make group calling capable of realizing phonetic and data synchronous transmission. It contains when up channel not occupied by other user equipment, short data transmission user equipment applying occupying up channel and reporting short data layer message, network side equipment responding said layer message, in FACCH and SACCH channel broadcasting said short data and then releasing up channel occupying. If up channel having been occupied by other user equipment, the short data transmission user equipment applying through network side equipment assigning one SDCCH sub-time slot, through said sub-time slot reporting short data layer message, network side equipment responding said layer message, releasing SDCCH occupying, and broadcasting said short data in group calling channel.

Description

technical field [0001] The invention relates to a group call wireless communication technology, in particular to a technology for realizing simultaneous interpretation of language and numbers during a group call. Background technique [0002] Global System for Mobile Communication (GSM for short) is a standard launched by the European Standardization Committee in 1992. It adopts digital communication technology and unified network standards to ensure communication quality and to develop more of new services for users to use. [0003] GSM-R, that is, the GSM system that serves railways, provides a common communication platform for railway staff, and can be used as a railway control system to meet the current and future needs of the railway network. It is a system facility designed, built and used directly for railway transportation production and railway information services. It mainly completes functions such as railway dispatching communication, station communication, emer...
