specific Embodiment approach 1

[0008] Specific implementation mode one: the following combination figure 1 and figure 2 This embodiment will be specifically described. The system for realizing the method is composed of a dispatching station DC, a cluster dispatching server TDS and a plurality of user terminals UE. The UDP socket server 1 of the dispatching station DC receives the wireless signal transmission of the trunking dispatching server TDS and executes the transmission protocol. The UDP socket of the dispatching station DC The interface client KS transmits wireless signals to the cluster dispatching server TDS and executes the transmission protocol, and all user terminals UE perform wireless communication with the cluster dispatching server TDS; the method includes the following steps: 1. The dispatcher DC sends a group to the cluster dispatching server TDS Call request signaling; 2. The cluster dispatching server TDS sends a group call response signaling to the dispatching station DC; 3. The datab...

specific Embodiment approach 2

[0010] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 3, the dispatcher can repeat the operation of stopping and continuing the recording multiple times, and multiple recording segments are spliced ​​together.

[0011] This selective recording method can complete the function of starting recording at any time and stopping recording at any time, and it can be repeated many times according to actual needs. The resulting fragments are spliced ​​together.

[0012] The realization of the selective recording method is based on the procedure of AMR real-time voice transmission. The system for implementing this method is mainly divided into seven modules according to functions: voice collection, voice playback, encoding and packaging, decoding and unpacking, socket sending, socket receiving, and recording processing.

[0013] The voice acquisition module collects data from the sound card and converts it into PCM encoded data packets and sends th...

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and embodiment one is that the following steps are also included between step five and step six: Voice right release signaling; A2. The trunking dispatching server TDS sends the voice right release signaling to the dispatching station DC; A3. The user terminal UE sends voice data, and the dispatching station DC displays the number of the user terminal UE currently having the speaking right. The above three steps can be repeated many times in one group call.

Abstract

The invention relates to a method for selectively recording during group calling of a dispatching desk in a digital trunking system, which is used for accessing broadband wireless multimedia information and overcomes the disadvantage that the conventional dispatching desk wastes the hardware resource of the dispatching desk when recording the whole group calling process. A device for implementingthe method consists of the dispatching desk, a trunking dispatching server and a plurality of user terminals. The method comprises the following steps that: the dispatching desk sends a group callingrequest signaling to the trunking dispatching server; the trunking dispatching server sends a group calling response signaling; the dispatching desk can start recording at any time by available recording function; a dispatcher can stop recording at any time; when the dispatching desk does not record, the dispatcher can continue to record at any time; the dispatching desk sends voice data; and when the group calling is finished, a dispatching desk database records calling end time and call duration, stores a voice record file and provides replay function.

Description

technical field [0001] The invention relates to a recording method for dispatching station group calls in a digital trunking system. Background technique [0002] The digital trunking system is a broadband wireless multimedia access system for key industry applications. It is a communication system established for the special service needs of government departments, government agencies, industry users, and enterprises and institutions. It has command, dispatch, and broadband multimedia data transmission. and other important functions. Digital trunking system is the R&D and industrialization of broadband multimedia wireless access system for key industries such as public security system. It can strengthen the country's ability to respond to public security, emergency handling, large-scale gatherings, rescue of natural disasters, defense against hostile forces, prevention of terrorist attacks, and emergency response to many emergencies. It can quickly deploy networks to ensur...
