Embodiment Construction

[0037]The method for handling call conflict of the present invention further determines whether to establish a voice channel connection for the two terminals by judging whether the two terminals have a call requirement for each other during the call conflict, that is, whether they are each other's called terminals. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Fig. 3 is the signaling flowchart of call conflict processing in the present invention, terminal 1 and terminal 2 shown in the figure establish voice path through the network to realize voice communication, and the dotted line part in it corresponds to the dotted line part in Fig. 2 respectively, represents call The time frame in which the conflict occurred. In order to solve the problem of call failure caused by call conflict in the prior art, the present invention makes corresponding modifications to the signaling flow of call establishme...

Abstract

A method for processing call conflict in a group communication system and a device based on the method are disclosed in the present invention. In the method of the present invention, judging a first terminal whether or not to call a second terminal when a network receiving a call request signaling of the second terminal calling the first terminal, if it does, then the network establishes the voice access for the first terminal and the second terminal. The device based on the method of the present invention establishes voice access for both conflict parties when the network generates call conflict. The call conflict processing method and device provided by the present invention, ensures the voice access successfully establishing when the call conflict generating, decreases the system call loss rate, promotes the system reliability.

Description

technical field [0001] The invention relates to a call processing technology in a wireless communication system, in particular to a method and device for processing call conflicts in a digital trunking communication system. Background technique [0002] The trunking communication system is a multi-purpose, high-efficiency wireless dispatching communication system, which has the characteristics of automatic channel selection, resource sharing, cost sharing, and channel equipment sharing. The digital trunking system is a trunking communication system using digital communication technology. [0003] In the digital trunking communication system, the voice communication between terminals is realized through the voice path established by call signaling. FIG. 1 is a schematic diagram of a signaling flow of a standard call in a trunking communication system in the prior art. Figure 1 includes three entities, namely terminal 1, terminal 2 and the network, wherein terminal 1 is the ...
