Problems solved by technology

This method is more complicated. Links need to be reassigned and released every time. It requires a lot of signaling transmission and cooperation from many aspects, and the efficiency is low.
Moreover, when the number of users in the cell is large and the link resources are limited, if there is no idle channel, this method cannot be used to transmit short data services

Embodiment Construction

[0027] In order to fully understand the technical content of the present invention, specific embodiments are given below, and the technical solutions of the present invention are introduced and explained in detail in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, when the voice group call service is in progress, the users in the group use the group call uplink channel to send short data, and the sending process is as follows:

[0029] While a group call is in progress, a listener user in a certain group call needs to send short data to another or some other group users. After the short data sender user MS1 prepares the short data to be sent, the sending process starts 101 . The sender user MS1 is an in-group user when performing a voice group call service.

[0030] In the group call competition state, MS1 applies for uplink channel occupancy right 102 and competes with other group call users for the right to speak.

[0031] After the network...

Abstract

The invention provides an implementation method for providing short data service by using a cluster group call service channel through an intra-group user during performing voice group call service. The method comprises a short data transmitting stage and a short data receiving stage; when a receiving party is not a group call user, a network facility transmits short data to a receiving party user through a main control channel, and transmits short data receiving success message to a transmitting party user by using a group call downlink channel; and when the receiving party is the group calluser, the network facility transmits the short data to the receiving party by using the group call downlink channel. Compared with the prior art, the method has the advantages of reducing resource waste of a reconstructed channel, along with easy implementation due to high sent short data rate. Because the time of occupying the channel during transmitting the short data is short, the group call service is affected little.

Description

technical field [0001] The invention relates to the technical field of digital trunking communication, in particular to a realization method for providing short data service by utilizing a trunking group call service channel. Background technique [0002] Mobile communication systems can be divided into public mobile communication systems and private mobile communication systems according to their nature of use. The trunking communication system belongs to a dedicated mobile communication system, which is a multi-purpose, high-efficiency wireless dispatching communication system that shares resources, shares costs, and shares channel equipment and services. In terms of network topology, the cluster communication system has a structure similar to that of the public mobile communication system: the terminal user MS communicates with the network facilities through the air interface. On both sides of the air interface, the equipment on the terminal side can be a mobile station ...
