Method, cluster server, and terminal for implementing mobile cluster pre-occupied priority call

Abstract

The invention relates to a method for realizing camp-on preference call of a mobile cluster, a cluster server and a terminal thereof. In an embodiment of the invention, conversation being in progress is confirmed in a camp-on preference group while the terminal sponsoring the camp-on preference call belongs to the camp-on preference group after the cluster server receives the camp-on preference call, and the call priority of the conversation is lower than the call priority of the camp-on preference terminal on the camp-on preference call priority and sends camp-on preference indicating information to the terminal, and the camp-on preference call between the terminal receiving the camp-on preference indication information and the terminal sponsoring the camp-on preference call is established by the cluster server, thus overcoming the disadvantages of the prior art, improving the reliability and timeliness of the camp-on preference call so as to simplify and standardize the treatment process of the camp-on preference call, reduce calling capacity and abnormality occurrence, simplify the treatment of a base-station system and realize interface standardization.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for realizing mobile cluster preemptive priority calls, a cluster server and a terminal. Background technique [0002] The mobile trunking communication system is a dedicated mobile communication system, and its reference diagram is shown in the attached figure 1 shown. The characteristic of the mobile trunking communication system is that the users dynamically share the wireless channel, the spectrum utilization rate is high, and the conversation is private. [0003] Because the trunking communication system has the characteristics of unique dispatching function, group call function, fast call establishment, high availability and security, it plays a huge role in the field of professional communication. [0004] An important feature of the mobile trunking call is that the call has several priority levels, and the high-priority call will have pri...

Problems solved by technology

[0008] However, in the prior art, the process of realizing preemptive priority calls is very unreliable. Before the preemptive priority call paging arrives, the terminal that is removed from the low priority call may receive paging from other calls, resulting in preemptive priority call paging. paging failure

Moreover, in the implementation process of the prior art, it is necessary to send pre-emptive priority paging, which increases the load of the paging channel, makes the process extremely complicated, and increases the difficulty of base station system implementation

In addition, the preemptive priority waiting time is too long, and the user experience of the terminal is not good.
