Abstract

The invention relates to a self-addressed communication method applied to an interphone, supporting a voice traffic and a data traffic and comprising the steps of subnet frequency allocation and automatic idle channel allocation, wherein the step of subnet frequency allocation comprises collection and uniform allocation of frequency resources, each user unit selects a subnet Zone with a number, each subnet Zone contains a frequency congregation without three-step intermodulation interference and adjacent-channel interference, and different user units use different frequency congregations without the three-step intermodulation interference and the adjacent-channel interference; and the step of automatic idle channel allocation comprises the steps of uniformly managing channels in each subnet Zone and automatically allocating the channels according to the traffic requirements. The self-addressed communication method applied to the interphone solves the problem of overlow using efficiency of frequency spectrum and simultaneously greatly enhances anti-interference capability on the basis of reserving the characteristics of rapid calling, simple use and the like of the current conventional mobile communication.

Description

technical field

[0001] The present invention relates to the field of LMR (Land Mobile Radio, LMR for short), land mobile wireless communication, more specifically, relates to a self-selecting address communication method applied to walkie-talkies. Background technique

[0002] Today, with the rapid development of my country's economy, walkie-talkies, as a flexible, convenient and fast means of information communication, are increasingly valued by people. Although the market is prosperous, it is quite chaotic. There are counterfeit and shoddy products flooding the market, professional walkie-talkies out of control, and radio order Chaos, hidden dangers to social security and other issues.

[0003] The current outstanding problems in the use of low-end walkie-talkie frequencies:

[0004] โ‘  The mutual interference between walkie-talkies is serious. At present, there are widespread irregular use of spectrum, even cross-band use, which is easy to be interfered by other devices a...
