Method and system for realizing group call service of public-private network trunking fusion system

Abstract

This application discloses a method for realizing group call service of public and private network converged trunking, including: for each trunking group, configuring group subscription information for the public and private trunking network in the evolved home subscriber server (eHSS), and the same The configuration of each member in the cluster group is the same; the cluster control function entity (TCF) in the private network cluster system acts as the main control center to perform unified scheduling and management of the cluster group, as well as business control and management of registered users of the private network cluster system. Management; the public network cluster control center acts as the sub-control center to control and manage the business of registered users of the public network cluster system. The application also discloses a system for realizing a group call service of a public-private network fusion trunking. The application of the technical solution disclosed in this application can solve the problems of complex configuration, waste of resources and inconsistent group members in the group call service of the existing public-private network convergence.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and system for realizing a group call service in a public-private network trunking fusion system. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications, and has a wide range of application markets in government departments, public safety, emergency communications, electric power, civil aviation, petroleum, ports and other fields. [0003] The TD-LTE system has the characteristics of high wireless spectrum utilization rate, fast transmission speed, simple structure, small delay, mature, stable and reliable, etc. B-TrunC (Broadband Trunking Communication: Broadband Trunking Communication) system takes TD-LTE as the core technology, and integrates the high speed and large bandwidth of TD-LTE with the characteristics of resource sharing, fast call establishment, and...

AI Technical Summary

Problems solved by technology

[0021] 1. The configuration is complex: For the fusion group, the group number needs to be configured on both the public network cluster network and the private network cluster network (hereinafter referred to as: public private network cluster network), and the mapping relationship between the two needs to be configured on the TCF side

When the code number plan on the public network cluster side changes, the configuration on the private network cluster side needs to be updated synchronously, and the configuration maintenance is more complicated

[0022] 2. Waste of resources: When a private network cluster user initiates a converged group call, and there is no called user registered in the public network cluster in the group, TCF will also send a call request to the public network cluster control center, resulting in a waste of public network cluster system resources

However, the group member information on the public network cluster side cannot be updated, resulting in inconsistent maintenance of the member information of the same cluster group by the public and private network system, which is prone to the problem that the business cannot be connected when the public and private network area is switched, and the user experience is poor
