Problems solved by technology
However, when a voice call group terminal is added, irrelevant calls will cause serious interference to normal work, and one person equipped with multiple wireless terminals will bring great inconvenience to the user's work and cause a waste of channel resources
Users cannot reasonably divide voice call groups according to actual business needs, which affects the effective use of the trunking system's business advantages

Embodiment Construction
[0048] figure 1The voice call method in a preferred embodiment of the present invention is shown, comprising the following steps:
[0049] The central device receives a group call establishment request including the group identifier from the terminal. The terminal sending the group call establishment request is a member of the group, and the group identifier belongs to the group. The group ID is previously set by the user in the central device according to the specific needs and stored in the central device. The group ID can be the inherent group identity identification of the group or a user-set identification for identifying the group master and slave. flag of the relationship. Understandably, the central device may include multiple cluster base stations and a control center.
[0050] The central device judges whether the group call setup request is a master group request or a slave group request according to the group identifier. The central device judges whether the gr...

The invention relates to a voice calling method, a voice calling terminal processing method, central equipment, a terminal and a voice calling system. The voice calling method comprises the steps of enabling the central equipment to receive a group call establishment request, judging whether the group call establishment request is a main group request or an auxiliary group request according to group identification, if the group call establishment request is the auxiliary group request, distributing an auxiliary group service channel for the group call establishment request, transmitting auxiliary group service channel distribution information on a control channel, if the group call establishment request is the main group request, distributing a main group service channel for the group call establishment request, transmitting main group service channel distribution information on the control channel, and broadcasting the main group service channel distribution information on the service channel. According to the voice calling method, the voice calling terminal processing method, the central equipment, the terminal and the voice calling system, a main-auxiliary mechanism is established, the main group service channel distribution information is broadcasted on the service channel, and therefore members in the conversion can timely receive the main group service channel distribution information and are prevented from missing important calls.
Description
technical field [0001] The present invention relates to the technical field of trunking communication, and more specifically, relates to a voice call method, a terminal processing method, a central device, a terminal and a system. Background technique [0002] In the trunking communication, the trunking system shares and flexibly allocates channel resources to wireless terminal voice call services in the system by controlling the voice channel. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing channel equipment and services . [0003] Generally, the talk group that supports voice is larger than the actual available channel resources, and the wireless terminals participating in the voice call switch to the designated channel for voice call after receiving the call channel command allocated by the system. However, in practical applications, a wireless terminal usually belongs to multiple service talk groups. Af...
