Isofrequency full-duplex communication method for digital non-center communication system

Abstract

The invention discloses a different frequencies full-duplex communication method, which is applied to the alternate communicating instance that is needed by the receiving and sending station, and increases the communicating efficiency. The technic proposal is that: the method comprises: (1) the frequency section of the digital communication system without a center is divided into a plurality of frequency points and time slots; (2) a plurality of frequency points are divided into controlling frequency spots and operation frequency spots; (3) the voluntary calling station check the state of theoperation frequency points to choose two different switching-in frequency points and time slots; (4) the voluntary calling station initiates the calling request; (5) the voluntary calling station switches to the assigned operation frequency points and time slots to wait for receiving the message from the called station; (6) the called station periodically checks the controlling frequency point, searches whether calling corresponding to itself exists, and talks to the voluntary calling station if calling corresponding to itself exists; (7) the voluntary calling station is communicated with thecalled station on the assigned frequency points and time slots; (8) the two stations release a channel after the calling is finished. The invention is applied in the digital communication system without a center.

Description

technical field [0001] The invention relates to a full-duplex communication method, in particular to a different-frequency full-duplex communication method of a digital centerless communication system. Background technique [0002] In the existing digital centerless communication system, the typical communication implementation mode is half-duplex. In the half-duplex mode, the calling station and the called station need to share the mastership of the channel in a time-division multiplexed manner. At the same time, only one party can occupy the communication channel as the originating station at the same time, and a certain protocol needs to be set. Transferring the mastership of the channel back and forth between the receiving and generating stations, arbitrating multiple parties' requests for channel mastering, etc., will bring a certain amount of resource overhead, and is not conducive to communication applications that require real-time interaction between the receiving a...

Problems solved by technology

In the half-duplex mode, the calling station and the called station need to share the master control of the channel in a time-division multiplexed manner. At the same time, only one party can occupy the communication channel as the sending station at the same time, and a certain protocol needs to be set. Transferring the mastership of the channel between the receiving and generating stations, arbitrating multiple parties' requests for channel mastering, etc., this will bring a certain amount of resource overhead, and is not conducive to communication applications that require real-time interaction between the receiving and generating stations Happening
