Method and system for authorization of speaking right in distributed fault-weakened cluster communication

Abstract

The present invention discloses a speaking right authorization method and system in distributed fault-weakened cluster communication. The method includes: a terminal sends a speaking right application to a base station; The source base station maintains the speaking right application terminal list, and forwards the speaking right application to other base stations at the same time; after the other base stations receive the speaking right application forwarded by the source base station, update and maintain the speaking right application terminal list; the base stations in the group call area sequentially Granting the speaking right to the terminal; the source base station deletes the authorized terminal from the list, and sends a speaking right notification message; after receiving the speaking right notification message triggered by the source base station, other base stations update and maintain the speaking right application terminal list, and The authorized terminal is deleted from the list, and a talk right notification message is sent to the rest of the terminals; it can ensure that the list of terminals applying for the talk right is synchronized to ensure that when the base station grants the talk right to the terminal, only one terminal gets the talk right at each moment .

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a speaking right authorization method and system in distributed fault weakened cluster communication. 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. In the system, a large number of wireless users share a small number of wireless channels, and the command and dispatch is the main application. It is a multi-purpose, high-efficiency wireless communication system. The trunking communication system has a wide range of application markets in the fields of government departments, public safety, emergency communications, electric power, civil aviation, petrochemical and military. [0003] The distributed fault weakening system refers to a communication system composed of base stations working in a fault weakening stat...

AI Technical Summary

Problems solved by technology

[0004] The existing application process for the right to speak under the weakened fault only considers the implementation under a single base station, that is, it is only within the scope of a single base station to judge whether the right to speak can be granted; however, in the distributed weakened fault system, the group call service is extended to multiple base stations , when considering the terminals of multiple base stations, there may be a situation that may apply for the right to speak at the same time; however, in the process of group call service, only one terminal can have the right to speak at each moment; Right, a single base station needs to exchange information with other base stations when granting the right to speak

[0005] It can be seen that the existing fault weakening application process is not suitable for distributed fault weakening systems
