Problems solved by technology

[0011] At present, the mobile communication services provided through the public telecommunication network cannot be used at any time and any place due to the limitation of network coverage.
However, the interface of the commonly used digital trunking communication system is not open, the standard is not open enough, the equipment cost is high, and the construction speed is slow, which cannot meet the needs of emergency communication

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the structure of an emergency trunking communication system is as follows: the TETRE terminal is connected to the IP-TETRE base station (iBTS) in a wireless communication manner, and the IP switching network is respectively connected to the IP-TETRE base station, the operation and maintenance center (OMC), and the dispatching station through the network cable 1. Taiwan, media gateway (MGW) and mobile switching center (iMSC) based on IP technology. The dispatcher communicates with the IP switching network through the standard SIP protocol; the media gateway communicates with the IP switching network through the standard SIP protocol

[0021] The IP switching network is connected to the SIP softswitch platform through the network cable 1 (the two communicate through the standard SIP protocol), and the SIP softswitch platform i...

Abstract

The invention discloses an emergency trunking communication system which belongs to the technical field of communication. The emergency trunking communication system has the following structure that a TETRA (Terrestrial Trunked Radio) terminal is connected with an IP (Internet Protocol)-TETRA base station in a wireless communication mode; and an IP switching network is respectively connected with the IP-TETRA base station, an operation and maintenance center, a dispatcher station, a media gateway and a mobile switching center on the basis of an IP technology through net wires. The emergency trunking communication system has the beneficial effects that currently, a global digital trunking communication system is rapidly developed and TETRA is to become a hot spot of seizing the future global trunking communication market; an iTETRA system has more flexible network architecture, higher data transmission speed and stronger user equipment functions; and particularly, after the IP technology and an SIP (System In Package) technology are adopted, the functions and services of the iTETRA system can well meet the private network commanding dispatching and emergency requirements of different industries.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an emergency trunking communication system. Background technique [0002] Today, with the rapid development of modernization, people's daily life has become more and more inseparable from communication tools such as telephones and computers. However, failures of communication networks often cause great inconvenience to people in their work and life. Therefore, the emergency communication system is getting more and more attention. [0003] The emergency communication system is a system that provides communication functions for better coordination of different departments and efficient handling of these emergencies in some emergency tasks or disaster situations. The trunking communication system has a unique dispatching function, a group call function, and a quick call feature, so it plays an important role in the emergency communication system. [0004] The ma...
