Roaming processing method for wireless dispatcher stations

Abstract

The invention provides a roaming processing method for wireless dispatcher stations. The method includes the following steps: a cluster control function entity (TCF) of a home location cluster core network of a wireless dispatcher station receives a register message sent by the TCF of a visiting location cluster core network of the wireless dispatcher station; the register message carries the location information of the visiting location cluster core network, and the carried terminal type is indicated as the wireless dispatcher station, and wireless dispatcher station initial register can be determined if the carried register type is indicated as initial register; and a location registration message can be sent to the TCF of a group home cluster core network of a group to which the wireless dispatcher station belongs after successful registration, and the location registration message carries the address of the TCF of the home location cluster core network. The method realizes the group call establishment, speech right application, speech right release and switching during group call processes when the wireless dispatcher station roams.

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
