Method and system for realizing group calling service of public private network cluster fusion system

Abstract

The invention discloses a public private network convergence cluster group calling service implementation method, which comprises the following steps of: for each cluster group, configuring group subscription information for a public private network cluster network in an evolved home subscriber server (eHSS), and configuring each member in the same cluster group to be the same; using a trunking control function entity (TCF) in the private network trunking system as a main control center to perform unified scheduling and management of trunking groups and service control and management of registered users of the private network trunking system, and the public network cluster control center is used as an auxiliary control center to perform service control and management on registered users ofthe public network cluster system. The invention further discloses a public and private network fusion cluster group calling service implementation system. By applying the technical scheme disclosedby the invention, the problems of complex configuration, resource waste and inconsistent group members in the existing public-private network fusion cluster group calling service can be solved.

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...

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
