Problems solved by technology

And in this method, each cluster terminal with group call authority only needs to be registered in the user registration information table and the group and user affiliation table to participate in the group call of the group, which makes it easy for non-group member terminals to join the group. During a group call, monitor its call information, which may easily lead to information leakage

Embodiment 1

[0049] figure 1 A flowchart showing the group call management method of the digital trunking system in Embodiment 1 of the present invention. The group call management method of the digital trunking system includes the following steps performed by the core network:

[0050] S1: Receive a group call request signal from the trunking terminal, where the group call request signal includes the terminal number of the trunking terminal and the calling group number corresponding to the calling group that the trunking terminal will participate in the group call.

[0051] In this embodiment, the core network receives a group call request signal sent by the trunking terminals whose terminal numbers are MS0001, MS0011, MS0021, and MS0031 through the base station to participate in the group call of the call group whose call group number is Grp01, and the terminal numbers are MS0002, The trunking terminals of MS0012, MS0022, and MS0032 send group call request signals to participate in the ...

Embodiment 2

[0077] figure 2 A flow chart showing the group call management method of the digital trunking system in Embodiment 2 of the present invention. The group call management method of the digital trunking system is executed by the trunking terminal, and cooperates with the group call management method of the digital trunking system executed by the core network in Embodiment 1. The method specifically includes:

[0078] S1: Send a group call request signal to the core network through the base station. Each group call request signal includes the terminal number of the trunking terminal and the calling group number corresponding to the calling group in which the trunking terminal is to participate in the group call.

[0079] In this embodiment, the trunking terminals whose terminal numbers are MS0001, MS0011, MS0021, and MS0031 send to the core network a group call request signal to participate in the group call of the calling group whose calling group number is Grp01 through the b...

Embodiment 3

[0085] image 3 A flow chart showing the group call management method of the digital trunking system according to Embodiment 3 of the present invention. The method is executed by the core network and the cluster terminal, and specifically includes the following steps:

[0086] S1: The trunking terminal sends a group call request signal to the core network through the base station, and each group call request signal includes the terminal number of the trunking terminal and the calling group number corresponding to the calling group that the trunking terminal wants to participate in the group call. In this embodiment, the trunking terminals whose terminal numbers are MS0001, MS0011, MS0021, and MS0031 send to the core network a group call request signal to participate in the group call of the calling group whose calling group number is Grp01 through the base station, and the terminal numbers are MS0002, MS0012 , MS0022, and MS0032 trunking terminals send to the core network a g...

Abstract

The invention discloses a group call management method and device of a digital trunking system. The method includes the steps executed by the core network: receiving a group call request signal from a trunking terminal, the group call request signal including the terminal number and the group call to be participated in The calling group number corresponding to the calling group; determine whether the group attribute is a security group, and whether the cluster terminal is a group member terminal of the calling group; the group attribute includes a security group and a flexible group; if the group attribute is a security group, and is not a calling group If the group member terminal of the paging group is used, the trunking terminal is restricted from joining the group call of the calling group; if the group attribute is a flexible group, or the terminal is a member terminal of the calling group, the trunking terminal is allowed to join the group calling of the paging group. The method can prevent the leakage of the call information of the security group due to the eavesdropping of the non-group member terminals, and the process can effectively save system resources and improve the processing speed of the cluster system.

Description

technical field [0001] The invention relates to the field of digital trunking system communication, in particular to a group call management method and device for a digital trunking system.
