Method and system for performing distributed queue control on speech right in PoC session

Abstract

The invention discloses a method and a system for performing distributed queue control on speech right in a push-to-talk over cellular (PoC) session. The system comprises a plurality of PoC user terminals participating in the PoC session and PoC servers that the PoC user terminals belong to. The method comprises the following steps that: when PoC users participating in the session belong to a plurality of PoC servers respectively, a speech request of each PoC user is saved in a local waiting queue of the PoC server that the PoC user belongs to, and the PoC servers are used to maintain respective local waiting queues respectively, and sequentially grant the speech right to the PoC users corresponding to the speech requests in the local waiting queue according to the global position identification of the speech request at the same time. The method and the system belong to the technical field of mobile communication, not only can meet the requirement of the PoC system on the waiting of the speech request, but also can overcome the disadvantages of speech right centralized control technology.

Description

technical field [0001] The invention relates to a method and system for performing distributed queue control on speaking rights in a PoC session, and belongs to the technical field of mobile communication. Background technique [0002] With the rapid development of the third generation 3G (3rd Generation) mobile communication technology, the PoC (Push to Talk over Cellular) service, which is one of the 3G symbol applications, has also attracted widespread attention. PoC is an instant two-way cluster communication service. Mobile terminal users only need to press a key like using a walkie-talkie without dialing to quickly establish a half-duplex multimedia session with multiple users within the network coverage. With the characteristics of wide signal coverage, high utilization rate of network resources, and flexible billing methods, it is regarded as the next-generation killer service after the short message service. [0003] see figure 1 , introducing a schematic diagram ...

AI Technical Summary

Problems solved by technology

If the central control node is overloaded or even fails, the processing of the floor-related control messages will be affected by it, resulting in longer waiting delays and affecting user experience and satisfaction. Therefore, TBCP has inherent disadvantages of the centralized mechanism: The central control node has high maintenance costs, is prone to control bottlenecks, has poor robustness, and poor scalability, etc.
