Problems solved by technology

However, it is not yet possible to preempt services for the PTT priority within the group
After the group call is established, all mobile stations in the group have the same priority. Once a mobile station becomes the speaker, other listener mobile stations do not have the right to preempt the right to speak before it releases the right to speak, so it cannot meet the requirements of clustering. Department's special requirements for group call service

Embodiment Construction

[0048] The implementation method of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0049] The present invention is applicable to the group call process of the trunking wireless communication system based on the public network. The embodiments herein take the trunking wireless communication system based on the GSM public network as an example to illustrate the present invention.

[0050] In this embodiment, one or more independent dedicated control channels (SDCCHs) of the GSM communication system are set in advance as preempting independent dedicated control channels (Preempt_SDCCH), which are used for reporting PTT preemption information by the mobile station. The mobile station reports PTT preemption information through an access burst (AB) in the Preempt_SDCCH channel. In this embodiment, the base station subsystem (BSS) on the network side of the GSM communication system activates the Preempt_...

Abstract

The invention relates to a method for seizing communication right based on in-group priority in the communication, which comprises: setting a special control channel used by the group calling mobile station reports seizing information in the network; sending a in-group priority information of present user and the information of set shared special control channel to present group calling mobile station; when the mobile station receives the seizing instruction, if its in-group priority is higher than the in-group priority of present user, via set shared special control channel, reporting the access impulse (AB) with seizing request information; the network decodes AB to attain seizing request information, releases the ascending chain circuit possessed by present group caller, builds ascending chain circuit for said seizing mobile station in the group calling service channel, and makes seizing mobile station as present user to possess said ascending chain circuit to communicate. The invention can realize the seizing service on in-group priority of group communication system based on public network, to meet the demand of group users.

Description

technical field [0001] The present invention relates to a communication method based on a trunking communication system of a public communication network, in particular to a method for realizing a listener's mobile station preempting a speaker's mobile station according to the push-to-talk (PTT) priority in the group during the group call process of the trunking communication system method of speaking. Background technique [0002] The trunking communication system is a relatively economical and flexible command and dispatch communication system developed in recent years. It is widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, water conservancy and military units to meet The need for internal communication within the unit. [0003] Initially, the trunking communication system adopts the cluster private network to build a network. However, since each group independently builds a cluster private netw...
