Embodiment 1

[0047] See figure 1 , figure 1 This is a schematic diagram of an audio and video backhaul link establishment process in Embodiment 1 of this application. The specific steps are:

[0048] Step 101: When the cluster core network side server receives the call request message sent by the calling terminal, it determines the main media format information for establishing the audio and video backhaul link according to the media format information carried in the call request message.

[0049] Refer to Table 1. Table 1 is the content contained in the message sent when a call request (CALL REQUEST) is initiated in an embodiment of the application.

[0050]

[0051] Table 1

[0052] In Table 1, in the call request initiated by the corresponding calling terminal, the difference from the existing implementation is Called Number [MAX_UE_NUM], and there can be multiple cells.

[0053] That is, the number of Called Number in the call request message sent by the calling terminal is at least one, that i...

Embodiment 2

[0094] See figure 2 , figure 2 This is a schematic diagram of the calling terminal initiating the release of the audio and video backhaul link in the second embodiment of this application. The specific steps are:

[0095] Step 201: When the core network server receives the call release request sent by the calling terminal, it releases the audio and video backhaul links with the calling terminal and the called terminal respectively.

[0096] Step 202: When the release of the audio and video backhaul link with the called terminal is completed, send a backhaul release result indication to the calling terminal to notify that the audio and video backhaul link between the calling terminal and the called terminal has been released.

[0097] When the calling terminal initiates a release request, the core network server, the calling terminal, the called DC, and the called UE can release at the same time, that is, there is no sequence relationship between the three.

[0098] For the calling t...

Embodiment 3

[0118] See Figure 4 , Figure 4 This is a schematic diagram of the process of adding a called terminal in the third embodiment of this application. The specific steps are:

[0119] Step 401: When the core network server receives the return instruction message of the newly added called terminal sent by the calling terminal, it establishes an audio and video backhaul link with the newly added called terminal.

[0120] Step 402: When the establishment of the audio and video backhaul link with the called terminal is completed, send a backhaul establishment result indication to the calling terminal to notify that the audio and video backhaul link between the calling terminal and the called terminal has been established.

[0121] Take the simultaneous addition of a called UE and a called DC as an example to describe the process of adding a called terminal:

[0122] In the first step, the calling UE informs the core network server of the need to add audio and video back to the called termin...

Abstract

The invention provides a method for establishing an audio and video return link in a broadband trunking system, which comprises the following steps that: when a trunking core network side server receives a call request message sent by a calling terminal, determining main media format information for establishing the audio and video return link according to media format information carried in the call request message; respectively establishing audio and video return links with the calling terminal and the called terminal according to the determined main media format information; wherein the called terminal comprises a called user terminal UE and / or a called dispatching desk DC; and when the establishment of the audio and video return link with the called terminal is completed, sending a return establishment result indication to the calling terminal, and notifying the calling terminal that the audio and video return link with the called terminal is established. According to the method, the audio and video return link can be rapidly established, and then audio and video return is carried out.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for establishing an audio and video backhaul link in a broadband cluster system. Background technique [0002] The broadband trunking system is mainly composed of wireless terminals, dispatching stations, trunking base stations, and trunking core networks. It provides broadband access and broadband trunking functions, and features rich functions, convenient operation and maintenance, and flexible deployment. The voice service is the most important means and the most dependent communication method in the command and dispatch function of the private network. The video service directly and objectively reflects the true information of various events, and is indispensable for the dispatching commander to correctly judge the scene situation and specify the action plan. Important reference. [0003] The video dispatch service in the private network command and dispatch...
