Roaming processing method of wireless dispatcher

Abstract

This application proposes a wireless dispatching station roaming processing method. The method includes: the cluster control functional entity TCF of the home cluster core network of the wireless dispatcher receives a registration message sent by the TCF of the visited cluster core network of the wireless dispatcher, and the registration message carries the location of the visited cluster core network information, the carried terminal type indication is wireless dispatcher, and the registration type indication carried is initial registration, then it is determined that the wireless dispatcher is initially registered, and after successful registration, the group to which the wireless dispatcher belongs belongs to the TCF of the cluster core network. A registration message, where the location registration message carries the address of the TCF of the home cluster core network. The application realizes group call establishment, speech right application, speech right release and group call switching when the wireless dispatching station is roaming.

Description

technical field [0001] The invention relates to the field of trunking technology, in particular to a roaming processing method of a wireless dispatching station. Background technique [0002] The dispatcher console is a unique terminal in the cluster system, which provides the dispatching and management functions of cluster services for dispatchers or operators with special authority. The main product form of the current dispatcher is a wired dispatcher, which is directly connected to the cluster core network, and transmits control signaling and business data between the dispatcher and the cluster core network through the D interface (that is, the interface between the dispatcher and the cluster core network). . [0003] With the increasing complexity of cluster business scenarios, the functional requirements of the wireless dispatcher are proposed. The wireless dispatcher is connected to the cluster core network through a wireless module, and its wireless link has a certai...

AI Technical Summary

Problems solved by technology

[0007] The wireless dispatcher carries the D interface signaling and service data through the user plane of the wireless module. The existing technology only clarifies the group call establishment method when the group includes the wired dispatcher and roaming wireless terminals. The wired dispatcher only has a home location The cluster core network has no concept of roaming, and the wireless terminal uses the downlink shared channel to realize the group call service, which does not involve the D interface. Therefore, the group call implementation scheme for the wired dispatcher and wireless terminal in the multi-core network interconnection scenario cannot be directly applied to the wireless Dispatcher

Currently, there is no solution for the scenario where the group contains roaming wireless dispatchers
