Embodiment Construction

[0053] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0054] This embodiment provides a dynamic reorganization method to realize dynamic reorganization in a broadband digital trunking system based on TD-LTE. A cluster scheduling management center is added to the application layer of the system, and the cluster scheduling management center can be a cluster application server. The process of dynamic reorganization can be initiated by a wired dispatch station, a wireless dispatch station, or a user terminal with super terminal authority in the group; the dynamic reorganization process initiated by the wireless dispatch station and a user terminal ...

Abstract

The invention provides an achieving method of dynamic regrouping serve and a broadband digital cluster system. The method is applied to the broadband digital cluster system based on time division long term evolution (TD-LTE). The method includes that after a cluster scheduling management center receives dynamic regrouping requests, authentication is conducted to objects sending the requests and users in operation objects carried in the requests; the dynamic regrouping requests further carry operation indication information; after the authentication is passed, the cluster scheduling management center sends group user information updating requests to a mobile management entity (MME), and the group user information updating requests carry label information of all users inside groups related by the operation; and after MME receives the group user information updating requests, corresponding users conduct updating of user group information through a group paging method. The achieving method achieves a dynamic regrouping function through minimal standard agreement modification, and is an important constituting part of the broadband digital cluster system based on TD-LTE.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing a state reorganization service and a broadband digital trunking system. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatch needs of industry users. A large number of wireless users in the system share a small number of wireless channels. The main application is command and dispatch. It is a multi-purpose and high-performance Wireless communication system. The trunking communication system has a wide range of applications in the fields of government departments, public security, emergency communications, electric power, civil aviation, petrochemicals, and the military. [0003] With the rapid development of mobile Internet and the large-scale construction of global wireless cities, broadband has become the development trend o...
