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 scheduling server TDS and executes the transmission protocol, and all user terminals UE perform wireless communication with the cluster scheduling server TDS; the method includes the following steps: 1. The dispatcher DC sends a single message to the cluster scheduling server TDS Call request signaling; 2. The cluster dispatching server TDS sends a single-call response signaling to the dispatching station DC; 3. Th...

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 a single call.

Abstract

The invention discloses a selective recording method for a dispatcher station single call in a digital trunking system, and relates to a recording method for the dispatcher single call in the digital trunking system. The method is used for broadband wireless multimedia information access and overcomes the defect of wasting hardware resources of a dispatcher station in a process of recording an overall signal call by the conventional dispatcher station. Devices for implementing the method comprise the dispatcher station, a trunking dispatching server and a plurality of user terminals. The method comprises the following steps that: the dispatcher station transmits a single call request signaling to the trunking dispatching server; the trunking dispatching server transmits a single call response signaling; the dispatcher station allows to use a record function so as to start recording at any time; a dispatcher can stop recording at any time; in a non-recording state, the dispatcher can continue recording at any time; the dispatcher transmits voice data; and when the single call finishes, a dispatcher station database records the call end time of the call, records call duration, stores a recording file and provides a playback function.

Description

technical field [0001] The invention relates to a recording method for a single call of a dispatching station 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 t...
