Embodiment Construction

[0044] The main idea of ​​the present invention is: after the high-priority user preempts the current speaker, the BSC replies to the MSC with an UPLINK REQUEST CONFIRM message, and the MSC considers that the group call channel uplink is occupied by the original speaker before receiving the UPLINK REQUEST CONFIRM, Then it is considered that the uplink of the paging channel is occupied by the new talker.

[0045] The specific technical solution of the present invention is: after the MSC replies the confirmation message to the BSS in the step 7 of the existing process, the MSC records that the new speaker starts to occupy the uplink; and in the step 7N of the present invention, after the MSC replies the confirmation message to the BSS, the MSC still Record the old speaker accounted for the upper row, as shown in Figure 2;

[0046] Step 11. After releasing the original speaker, the BSC sends an UPLINK REQUEST CONFIRM message to the MSC. After receiving the UPLINK REQUEST CONFIRM...

Abstract

This invention discloses a snatching method and a system for up-line multicall channel used in radio cluster communication system, in which, the method includes: when a multicall channel up-line transmits a snatch request and it is successful, a BSC where a new speaker locates writes back a confirmation message for the up-line request to the MSC, after receiving the confirmation message, the MSC begins registering that the multicall channel up-line is occupied by a new speaker, otherwise, it registers that it is occupied by the original one.

Description

technical field [0001] The invention relates to the field of trunking wireless communication, in particular to a method and system for preempting an uplink group call channel. Background technique [0002] The trunking wireless communication system (hereinafter referred to as the trunking 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 internal communication needs of each unit. [0003] In a trunking system, when a group call is initiated, a group of users in a specific area can simultaneously join the group call and monitor the speaker. There can only be one speaker at a time. When the speaker finishes speaking, other users can become speakers by pressing the PTT button (Push to talk). The speaker can occupy the uplink group c...
