Embodiment Construction

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

[0046] like 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 voice...

Abstract

The invention provides a method and a system for establishing a cluster service. The method for establishing the cluster service comprises following steps: group calling initiating BSS receives a voice group calling request sent by an initiator and sends a service request message carrying supported voice coding-decoding types to a mobile switching center (MSC) according to the voice group calling request; the MSC receives a first group calling establishing request message sent by the initiator after the service of the MSC and the initiator is connected, wherein the first group calling establishing request message carries the voice coding-decoding types supported by the initiator and the group calling receiving BSS information; the MSC selects a first voice coding-decoding type for the use of the group calling initiating BSS through the group calling initiating BSS according to the service request message and the first group calling establishing request message; the MSC selects a second voice coding-decoding type for the use of the group calling receiving BSS through the group calling BSS according to the first voice coding-decoding type; group calling receiving BSS assigns the selected results to corresponding users. According to the technical scheme, by means of the IP-based A interface, voice group calling service is carried out with increased voice service quality and reduced network cost.

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 powerful 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 tow...
