Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the embodiments.

[0038] The present invention provides a solution proposed by the present invention, and proposes a concept of a virtual signaling channel, linking satellite links (including but not limited to Beidou short messages, GPS, GLONASS, and low-orbit satellites, etc.) As the virtual signaling channel and backup service channel of the autonomous frequency-selective short-wave radio station, it can exchange idle channel information in real time, update the dynamic frequency hopping list in real time, change the voice key frame encryption key in real time, and can be used as a backup when the communication of the autonomous frequency-selective short-wave radio station is interrupted The business channel keeps the business unimpeded between self-selected frequency-selected short-wave radio stations.

[0039] The present invention proposes a passable frequency set decision function module...

Abstract

The invention discloses a communication system for a virtual signaling channel of an autonomous frequency-selective short-wave radio station. The communication frequency set decision function module, the frequency hopping list decision function module, the encryption key decision function module, and the backup channel decision function module proposed by the present invention utilize the out-of-band virtual signaling channel, which can help to realize fast communication between the calling party and the called party: 1) Real-time exchange of available frequency sets, 2) Real-time exchange of frequency hopping lists, 3) Real-time exchange of voice key frame encryption key information, 4) Real-time backup of autonomous frequency-selective shortwave radio links. The concept of the virtual signaling channel proposed by the present invention uses the satellite link as the virtual signaling channel and standby service channel of the autonomous frequency-selective shortwave radio station to realize real-time exchange of idle channel information between the calling party and the called party, real-time update of the dynamic frequency hopping list, and real-time change Voice key frame encryption key, and can be used as a backup service channel when the communication of the self-selected short-wave radio station is interrupted, to maintain the basic information exchange between the self-selected short-wave radio stations and keep the business smooth.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a communication system for a virtual signaling channel of an autonomous frequency-selective short-wave radio station. Background technique [0002] The current working method of the autonomous frequency-selective shortwave radio station is that the radio station enters the broadband reception waiting state after it is turned on, and then initiates a trial call on the experience frequency point and the real-time spectrum sensing idle channel. The radio adopts full-band broadband signal analysis and processing technology, and has the ability to capture call signals. When the captured address is the address of the local party, a response signal is sent on the frequency, and then the two parties conduct detection, and find the best frequency for communication between the two parties to establish a link for business communication according to the frequency optimization...
