Embodiment Construction

[0035] In order to better understand the technical solution proposed by the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Step S1:

[0037] Before the user initiates a link building request, the frequency (frequency band or frequency set) must first be obtained. For short-wave users, the frequency management system allocates the working frequency band and writes it into the UIM card (subscriber identity module, similar to the SIM card of a mobile phone). The frequency band is divided into Day band, night band. Under normal circumstances, it switches to the daily frequency band at 6:00 am, and switches to the night frequency band at 6:00 pm. The switching time is configurable, and the switching time varies slightly according to different seasons.

[0038] In addition to allocating the working frequency band, the shortwave frequency selection control device will use the b...

Abstract

The present invention provides an implementation method for a shortwave-based fast link establishing system. According to the method, a shortwave frequency selection control device selects an optimal communication frequency set, three times of signaling interaction are performed based on the frequency set, and in a networking process, a shortwave wireless link system is established fast according to a multi-user conflict processing policy of nodes. The method improves communication rate and success rate of service communication, and is used for implementing a shortwave networking system.

Description

technical field [0001] The invention belongs to the field of communication, and relates to a short-wave link building method, in particular to a realization method of a short-wave fast link building system. Background technique [0002] Short-wave communication has been widely used in the fields of military communication, public security and frontier defense, emergency disaster relief, diplomacy, ocean monitoring and other fields due to its long communication distance and difficulty of complete destruction. In the implementation of diversified support tasks in the future, short-wave communication is an important means of communication to support combat command. Due to the time-varying and multipath characteristics of the short-wave channel, the signal will be severely attenuated when it reaches the receiving end through the short-wave channel, resulting in low reliability and passability of traditional short-wave communication. [0003] Chinese patent CN104093193A provides ...
