Embodiments of the present invention provide a method and device for sending signaling multicast messages in a cluster communication system. The method includes: adjusting the first cycle according to the number of signaling multicast messages sent per unit time and the number of signaling multicast messages allowed to be sent by the signaling multicast channel per unit time, the first cycle is The period of the signaling multicast message of the activated group, the first period is greater than the second period, the second period is the period of sending the signaling multicast message of the newly created group, and the adjusted first period is used to send the activated group Signaling multicast message. In the method of the embodiment of the present invention, by using a smaller period to send the signaling multicast message of the newly created group, and using a larger period to send the signaling multicast message of the activated group, on the premise of satisfying the group establishment delay In this way, the resource utilization rate of the air interface is improved, the sending period is adjusted according to the number of messages, and the reliability of the group service is improved when the service bursts.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of trunking communication, and in particular to a method and device for sending signaling multicast messages in a trunking communication system. Background technique [0002] The Mission Critical Push To Talk (MCPTT) service is defined in the 3rd Generation Partnership Project (3GPP for short), and the MCPTT service is based on the Long Term Evolution (Long Term Evolution, short for: LTE) broadband bearer to solve the trunking call problem in the field of emergency communications, which includes public safety applications (such as fire alarm and public security systems) and general commercial applications (such as railway and urban subway systems). [0003] The group call service is defined in 3GPP MCPTT. In the group call, both the multicast technology and the unicast technology can be used between the server and the monitoring terminal. When the multicast technology is used for ...
