Embodiment Construction

[0045] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0046] Such as figure 1 Shown is a flow chart of the method for establishing a cluster service provided by Embodiment 1 of the present invention, please refer to figure 1 , the method includes:

[0047] S101: The group call originating base station subsystem receives the voice group call request sent by the initiator, and sends a service request message carrying the supported voice codec type to the mobile switching center according to the voice group call request. Specifically, before executing this step S101, the group call originating base station subsystem receives the voice group call request sent by the originator, it also includes: the group call originating base station subsystem receives the random access channel request message sent by the originator, and The initiator allocates a data channel; and then receives the vo...

Abstract

The present invention provides a method and system for establishing a trunking service. The method for establishing a trunking service includes: the group call initiating BSS receives the voice group call request sent by the initiator, and sends a voice group call request carrying its support to the mobile switching center according to the voice group call request. The service request message of the voice codec type; after the MSC is connected to the service of the originator, it receives the first group call establishment request message sent by the originator that carries the voice codec type supported by the originator and the group call reception BSS information; the MSC According to the service request message and the first group call establishment request message, select the first speech codec type used by the group call originating BSS through the group call originating BSS; the MSC selects the group call receiving BSS to use according to the first speech codec type through the group call BSS The second voice codec type: the group call receiving BSS assigns the selected result to its corresponding user. This solution can improve the voice service quality and reduce the network cost when the voice group call service is performed through the IP of the A interface.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for establishing trunking services. Background technique [0002] The current development trend of the communication industry: the rapid growth of communication business volume, and the rapid development of IP (Internet Protocol network interconnection protocol) data service demand, this trend constitutes a strong driving force for network transformation. Operators urgently need to provide richer data services to all-IP networks, reduce costs, and increase profits through cost-effective and differentiated services. The evolution to all-IP has become the consensus of mainstream operators at home and abroad. [0003] In the Global System for Mobile Communications (GSM) voice communication system, the realization of the IP-based wireless access network, that is, the gradual promotion of the IP-based A interface and Abis interface, is a key factor towar...
