System, device and method for realizing business telephone on microwave communication network

Abstract

The present invention provides a system, device and method for realizing business telephone on microwave communication network. The system includes a main control switching device of node equipment and a plurality of modulation and demodulation units; wherein, the main control switching device is configured with a local voice channel and multiple Air interface voice channels, within a certain period of time, for each voice channel of this call, the voice data of other voice channels other than this voice channel that generate new voice information will be mixed, and the mixed voice data of each air interface voice channel will be mixed. The data stream is encapsulated into a voice data packet and sent to the corresponding modem unit; the modem unit will extract the voice data from the received voice data packet, insert it into the air interface data frame and send it to the microwave air interface through modulation. The invention enables engineering personnel to flexibly carry out point-to-point business, multi-party conference business and cross-point business activities.

Description

technical field [0001] The invention relates to microwave communication network service telephone technology, in particular to a system, device and method for realizing microwave communication network service telephone. Background technique [0002] Microwave communication technology has been around for more than half a century. It refers to the way of relaying (relay) communication between line-of-sight through radio wave space by using microwave frequency as the carrier to carry information. Currently, digital microwave communication, optical fiber and satellite are called the three pillars of modern communication transmission. [0003] Digital microwave communication equipment can be divided into small-capacity point-to-point equipment and medium- and large-capacity node equipment according to the transmission capacity. Traditional point-to-point devices can only transmit user data to one air interface at a line-of-sight distance. However, with the rapid increase of use...

AI Technical Summary

Problems solved by technology

[0013] (1) The point-to-point business phone can only be adapted to the traditional point-to-point microwave network. For today's multi-node microwave equipment, it cannot meet the needs of supporting multiple directions, so it cannot meet the needs of multi-party calls;

[0014] (2) Although the business phone between the cross-node devices can meet the call from the node device to any node device in the network, it needs to add a DTMF dialing module, which not only increases the hardware cost, but also the software implementation of the CPU monitoring unit is more complicated, and at the same time The use of Field Programmable Gate Array (FPGA, Field Programmable Gate Array) logic to extract, retransmit and perform multiple decomposition of the voice business data transmitted over the air interface will bring certain troubles;

[0015] (3) The business calls between point-to-point node devices or cross-node devices cannot meet the needs of multi-node business calls in modern microwave communication networks
