Problems solved by technology

However, the existing network cannot judge whether the call to be initiated by the mobile station is a group call / multicast call before allocating the signaling channel, so the process of setting up the group call / multicast is often too long, which affects the timely development of the group call service

Embodiment Construction

[0046] The basic principle of the present invention is: when the group call / multicast is established, the signaling connection between the mobile station and the network is established by adopting the immediate assignment process of immediately assigning the service channel. The channel request is the only message that the mobile station can report before the signaling channel is allocated in the immediate assignment process, so the group call / multicast call type is indicated in the channel request cause value, and the network immediately assigns a traffic channel after identifying the call type It is used for signaling interaction when group call / multicast is established.

[0047] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0048] Referring to FIG. 3 and FIG. 4 , they are respective...

Abstract

The invention relates to a multicast / group cast building method and relative system, wherein said method comprises that: a, sending channel request that requests to distribute service channel; b, feeding back confirmation; c, distributing the service channel. The invention can use quick service channel as the signal exchange channel in multicast / group cast building process, to accelerate the process.

Description

technical field [0001] The present invention relates to the group call / multicast technology in the field of mobile communication, in particular to a group call / group call that realizes fast group call calls in a trunked communication network based on GSM (Global System for Mobile Communication, Global System for Mobile Communications). Broadcast establishment method and system. Background technique [0002] GSM is a common mobile communication system at present. In addition to realizing basic mobile communication services, people have also developed a technology for realizing group call communication in GSM. Take the GSM-R system, the main application system of group call / multicast technology, as an example. This system is the earliest communication system to realize group call / multicast, and it is a system developed by Europe for railway mobile communication. GSM-R uses GSM communication technology as the service bearer, and provides VGCS (Voice Group Call Service) to the ...
