Problems solved by technology

When the cluster group belongs to the management of multiple cluster control centers, if the existing group-anchor cluster control center mode is adopted, when the user of the non-group-anchor cluster control center initiates a group call, due to the need to pass the IP link to the Call establishment signaling is routed from the current cluster control center to the anchor cluster control center, the call establishment delay will inevitably increase, and due to the unpredictability of IP link transmission, the success rate of call establishment will be reduced

Embodiment 1

[0035] figure 1 It is a flow chart of a method for calling a cluster group in a multi-cluster control center provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of establishing a cluster group call in a cluster group with multiple cluster control centers. The method can be performed by a calling device of a multi-cluster control center cluster group, and the multi-cluster control center cluster group call device is configured in the cluster control center. The method specifically includes the following steps:

[0036] Step 110, receiving the cluster group information sent by the cluster dispatching center.

[0037] Among them, the cluster scheduling center can obtain the cluster user terminal or cluster group information of each organization. When a special situation occurs, the cluster scheduling administrator can reorganize the cluster user terminals or cluster groups of different organizations, and reorganize the information into clu...

Embodiment 2

[0055] figure 2 It is a flowchart of a call method for a multi-cluster control center cluster group provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of Embodiment 1, and the operation of granting the speaking right is further added. The method is specific Including the following steps:

[0056] Step 210, receiving the cluster group information sent by the cluster dispatching center.

[0057] Step 220: According to the call establishment request initiated by the subordinate trunking user terminal, it is determined to establish a trunking group call when the call is not established, and send a call establishment request to other trunking control centers of the trunking group according to the information of the trunking group , to request other trunking control centers to send the call establishment request to subordinate trunking user terminals, so that the trunking user terminals of other trunking control centers join the trunking g...

Embodiment 3

[0071] image 3 It is a flowchart of a call method for a multi-cluster control center cluster group provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiment, and further adds that the current group speaking right state is occupied state The processing operation when the group anchor cluster control center receives the speaking right application request, the method specifically includes the following steps:

[0072] Step 310, receiving the cluster group information sent by the cluster dispatching center.

[0073] Step 320: According to the call establishment request initiated by the subordinate trunking user terminal, it is determined to establish a trunking group call when the call is not established, and send a call establishment request to other trunking control centers of the trunking group according to the information of the trunking group , to request other trunking control centers to send the call establishment...

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...
