Embodiment Construction

[0040] In order to make the object, technical solution and beneficial effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0041]When an emergency or important situation occurs in the cluster group, or when all cluster group members need to be notified due to an emergency situation, the scheduler can send an emergency mode instruction to the network side. The network can predefine a series of DTMF (Dual Tone Multi Frequency) codes to identify the emergency mode indication. The DTMF code value can be determined according to the specific operation, but it cannot be related to the start of speech, the end of speech, or the clearing of the emergency mode indication. The sequence is the same.

Abstract

The invention discloses a method, equipment and a system for managing emergency call in group calling business. Through the setting of initiating or terminating emergency call in the group calling business by a dispatcher in a group system, the management of establishment or elimination of emergency call by the dispatcher in the group calling business is realized, the dispatcher also can inform members taking part in the group calling business to enter a group emergency mode when encountering an important emergency circumstance. In addition, the dispatcher can realize timely recovery of the group emergency mode.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for emergency call management of a communication group call service. Background technique [0002] Trunking wireless communication system, hereinafter referred to as trunking system, is a relatively economical and flexible command and dispatch communication system developed in recent years, widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, water conservancy and Military and other units to meet the needs of internal communication of each unit. [0003] The existing cluster system manages a group of users as a cluster. When a member in the group initiates a session, the content of the session can be notified to all users of the group within the signal coverage of the cluster system. with the system. [0004] In order to realize intra-group cluster communication, the cluster sy...
