Frequency spectrum detection and frequency allocation system and method

Abstract

The invention discloses a frequency spectrum detection and frequency allocation system and method, which are used for reducing the overhead of a leasing network on frequency spectrum detection and improving the efficiency of frequency spectrum detection. The frequency spectrum detection and frequency allocation system comprises a frequency management device, and frequency spectrum detection devices respectively arranged for each frequency allocation area of an authorized network, wherein the frequency spectrum detection devices are used for carrying out frequency spectrum detection on the frequency allocation areas of the targeted authorized network and reporting the detected frequency occupation information of the frequency allocation areas to the frequency management device; and the frequency management device is used for determining the working frequency used by each base station in the leasing network according to the frequency occupation information of the authorized network, reported by the frequency spectrum detection devices, so as to avoid interfering the authorized network.

Description

technical field [0001] The present invention relates to the field of radio technology, in particular to a spectrum detection and frequency configuration system and method. Background technique [0002] Cognitive radio technology studies the problem of dynamically sharing spectrum among multiple networks. When the authorized frequency of a network is not occupied, it can be temporarily lent to other networks for use. A network with authorized frequencies can be called an authorized network; other networks can find frequency holes by detecting frequencies occupied by air signals and obtain information about available idle frequencies. Then for use, a network that borrows frequencies may be referred to as a leased network. When the authorized network re-occupies the frequency, the leased network needs to return the borrowed frequency in time and switch to other idle frequencies. [0003] In the existing technology, for leased networks using mobile cellular technology, all bas...

Problems solved by technology

In this case, if all base stations and all terminals in the LTE network have the function of spectrum detection, it will cause a waste of spectrum detection resources; and when the base station or terminal is far away from the signal transmission center of the broadcast network, that is, the broadcast tower , the required spectrum detection time is longer, which makes the spectrum detection result inaccurate and reduces the efficiency of spectrum detection
