Problems solved by technology

[0003] However, in the existing group joining process, once the monitoring terminal detects that there is a group activation, it will send a group joining request to the base station
If a large number of listening terminals detect group activation at this time, they will send a group joining request to the base station at the same time, which will cause a signaling storm on the air interface and affect normal trunking communication services

Embodiment Construction

[0024] figure 1 It is a flow chart of an embodiment of a method for joining a monitoring terminal in the trunking communication system of the present invention. As shown in the figure, the method includes:

[0025] Step 110, when the monitoring terminal in the current cell detects a paging message from the network side, it acquires a group joining period value C from the paging message.

[0026] Wherein, the monitoring terminal refers to the terminal that monitors the trunking service initiated by the speaker terminal; C is a value representing the duration, preferably an integer; the paging message can be, for example, a system information block carrying the group joining period value C (System Information Block, SIB for short) 21 system message, the definition of the message is as follows.

[0027]

[0028] Wherein, "groupJoinCycle" indicates the group joining cycle value C, and the unit is second; the default value is 0, indicating that the group joining process is init...

Abstract

The invention provides a trunked communication system, monitoring terminals and a joining method thereof. The joining method comprises the steps that when a monitoring terminal located in a current cell detects paging information from a network side, a cluster joining periodic value C is obtained from the paging information; when the monitoring terminal detects that a cluster is activated, the cluster is monitored, and a random value T is randomly selected from 0 to C; and the monitoring terminal launches a cluster joining process in a delayed mode to the network side according to the random value T. According to the joining method, the monitoring terminal launches the cluster joining process in the delayed mode to the network side according to the random value T, cluster joining moments of the monitoring terminals are evenly distributed in time to the greatest extent, signalling storm caused by a plurality of monitoring terminals joining a cluster at the same time is avoided, and therefore normal operation of a trunked communication service is guaranteed.

Description

technical field [0001] The invention relates to a trunking communication system, a listening terminal and a joining method thereof, and belongs to the technical field of Time Division-Long Term Evolution (TD-LTE for short) trunking communication. Background technique [0002] In the trunking communication system based on TD-LTE, when the monitoring terminal detects that there is a group activation, it first monitors the group, and then needs to notify the network side of the group that the monitoring terminal is monitoring through the group joining process, so that the network The side can know exactly which group the monitoring terminal is in [0003] However, in the existing group joining procedure, the monitoring terminal will send a group joining request to the base station once it detects that there is a group activation. If a large number of listening terminals detect group activation at this time, they will simultaneously send a group joining request to the base stat...
