Problems solved by technology

[0012] 2. It takes a long time to establish a private chat session
It takes a certain amount of time from exiting the group conversation to establishing a private call again, and there is also a certain delay in call establishment. For example, the delay in establishing a single call in the existing system is generally about 1.5-2 seconds

Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0051] In the embodiment of the present invention, on the basis of not changing the network structure of the existing trunking group call communication system, the calling MS sends a private communication request, the PTT server receives the private communication request, and establishes a private communication between the PTT server and the BSC / PCF The shared channel uses the private communication channel of the called MS to receive the private communication information of the calling MS, thereby realizing the private communication of the cluster members without exiting the group session.

[0052] Fig. 2 is a schematic structural diagram of a system for performing private communication in trunking group calls according to an embodiment of the present in...

Abstract

The invention discloses one set group call for private communication method and device, which comprises the following steps: set group dialogue main call mobile bench is connected to network through wireless interface to send private require to one key servo; PTT servo establishes private communication common signal channel to trigger RAN establishing and group dialogue; set dialogue main call MS sends private communication information to PTT servo to send the common communication information to RAN through private communication signal channel.

Description

technical field [0001] The invention relates to trunking group call communication technology, in particular to a method and device for private communication in trunking group call. Background technique [0002] Trunk group call communication technology was born in the 1970s. Its concept comes from walkie-talkies, and the user experience is very similar to that of walkie-talkies: simple, fast, and half-duplex calls. The earliest trunking group call communication system was an analog system. With the rise and development of digital trunking group call technology worldwide in the mid-1990s, with its advantages of fast connection, high spectrum utilization and flexible networking, Widely used in special mobile communication systems such as production scheduling, command and control, and conference calls, it plays an extremely important role in improving production and work efficiency and ensuring safety. [0003] Taking a trunk group including 3 trunk members as an example, FIG...
