Abstract

The invention discloses a calling method, device and system for a cluster group of a multi-cluster control center. The method comprises the following steps: receiving information of the cluster groupsent by a cluster scheduling center; and establishing a cluster group call when the call is not established according to a call establishing request initiated by a subordinate cluster user terminal, and sending the call establishing request to other cluster control centers of the cluster group according to the information of the cluster group in order to request the other cluster control centers to send the call establishing request to subordinate cluster user terminals, so that the cluster user terminals of the other cluster control centers join the cluster group call. According to the calling method, device and system, each cluster control center can establish the cluster group call, and the call establishing request does not need to be routed to a fixed group anchor cluster control center through an IP link to establish the cluster group call, thereby reducing the call establishing delay and increasing the success rate of call establishment.

Description

technical field

[0001] The embodiments of the present invention relate to wireless communication technology, and in particular to a method, device and system for calling a cluster group of a multi-cluster control center. Background technique

[0002] In the field of public safety communications, in some special cases, group communication between different organizations in multiple regions is required, and cluster users or cluster groups in different organizations are reorganized, so that no matter which organization the user initiates the group Communication, users of other organizations can receive the content of the communication.

[0003] In existing group communication standards, there is a fixed cluster control center for group communication, which is also called a group anchor cluster control center, and the control center performs group call establishment and group speaking right control. As we all know, group communication requires high latency. When the cluster gr...
