Abstract

The invention is suitable for the TETRA communication system field and provides a communication voice recording system used in a trans european trunked radio (TETRA) system. The system is based on computer networks. And an application program interface (API) server of the TETRA system is connected with at least one TETRA switchboard. The system comprises: a control module which is used for distributing voice distribution channels according to call events in the TETRA system and emitting a voice acquisition control instruction; at least one voice acquisition node which is used for collecting / stopping an collection of communication voices in distributed voice distribution channels according to the voice acquisition control instruction. The control module and the voice acquisition node are respectively arranged in two or more physical equipment or are integrated in a same physical equipment. In the invention, the communication voice recording system monitors the call events of the whole TETRA system, and dynamically distributes the corresponding voice distribution channels to the different voice acquisition nodes. Therefore, communication voice recordings of entire networks can be realized.

Description

technical field [0001] The invention belongs to the field of TETRA communication systems, in particular to a communication voice recording system used in the TETRA system. Background technique [0002] Transeuropean trunked radio (TETRA) digital trunked communication system (hereinafter referred to as "TETRA system") is a professional mobile communication system based on digital time division multiple access technology. An open system designed and formulated to meet the needs of communication. The TETRA system can provide multi-group command and dispatch services, short data services, packet data services and digital full-duplex mobile phone services on the same technical platform. Related services for multiple organizations. Rich service functions, higher frequency utilization, high communication quality and flexible networking make TETRA system widely used in my country's public security, urban emergency response, airport and other related departments in recent years. ...
