A method for controlling repeated transmission of group call data

Abstract

This application discloses a method for controlling repeated transmission of group call data. During the group call establishment process, the cluster server receiving the group call establishment request assigns a globally unique identifier for the current group call service, and the sender sends a group call establishment control signal to the receiver. The group call establishment control signaling carries the globally unique identifier of the group call, and the receiver establishes a GTP-U tunnel for the group call service according to the sender's instruction; the receiver establishes the GTP-U tunnel Finally, judge whether the current group call service has been established on the receiver side according to the globally unique identifier of the group call, if so, set the GTP-U tunnel state to be inactive, otherwise, set the GTP-U tunnel state to be active; The call service tunnel establishment result and the GTP-U tunnel status are fed back to the sender; the sender completes the establishment of the corresponding GTP-U tunnel according to the tunnel establishment result of the receiver, and only sends group data to the receiver through the activated GTP-U tunnel. call business data.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a TD-LTE broadband digital trunking communication system, and in particular to a method for controlling repeated transmission of group call data. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the needs of industry command and dispatch, and is oriented to various industry applications. Trunking communication systems are widely used in public security, transportation, public utilities, petrochemical industry, industry and commerce, and the military. Compared with the analog trunking communication system, the digital trunking communication system has many advantages such as high spectrum utilization rate, strong signal resistance to channel fading, high security and reliability, rich services, flexible and effective network management control, etc., and is currently the most widel...

Problems solved by technology

Eventually, data flooding in the network will result in severe system load and even system failure.

[0007] For base stations or core switching systems that receive repeated data transmissions, if the method of locally identifying and discarding repeated service data is adopted, the processing complexity of network element equipment will be increased, resulting in increased service data transmission delays, and affecting user perception of group call services. experience
