A method for recognizing authorized frequency points and an authorized frequency point management system

Abstract

The invention discloses a cognitive method of authorized frequency points. An authorized frequency point management system for storing and managing related information of authorized frequency points is set, and the authorized frequency point management system comprises an authorized frequency point system database management module, an authorized frequency point database and a perceptual system database management module; a perceptual system makes use of the authorized frequency point database to take the authorized frequency points, used in a target area, as frequency points prohibited to be used so as to realize evading; and for the authorized frequency points in neighboring areas, availability of the authorized frequency points in neighboring areas is judged through comprehensive consideration of service condition of the authorized frequency points in neighboring areas. With the scheme of the invention, the perceptual system not only can effectively evade the authorized frequency points and avoid interference to systems using the authorized frequency points, but also can reuse spectrum resource effectively so as to improve use ratio of the spectrum resource.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method for recognizing authorized frequency points and an authorized frequency point management system. Background technique [0002] With the continuous advancement of wireless communication technology and the vigorous development of the mobile Internet and Internet of Things industries, the demand for radio spectrum by various radio services has expanded rapidly, and spectrum resources have become increasingly scarce. On the one hand, especially with the deep integration of industrialization and informatization, users in various industries (such as electric power, petroleum, etc.) have put forward broadband requirements for wireless private networks, and traditional private network frequency bands have been unable to meet the needs of industry users; on the other hand , due to the business characteristics of industry users, the utilization rate of...

AI Technical Summary

Problems solved by technology

Due to the 12MHz frequency band of 223-235MHz, the frequency points are divided into 25kHz, a total of 480, and the processing complexity of perception measurement is relatively high.

If the licensed frequency point information is used as the fixed prior information of the perception system, on the one hand, the use of licensed frequency points in different regions is not the same, which will bring inconvenience to equipment production and maintenance; on the other hand, because the perception system has no authorized frequency points Site location, station height and transmission power information, missed detection will bring hidden node problems, causing the perception system to interfere with the system using authorized frequency points
