Problems solved by technology

At the same time, although some broadcast TV frequency bands are used for real-time TV signal transmission, the utilization rate of these frequency bands is very low, which not only increases user costs, but also is difficult to use as idle spectrum, reducing spectrum utilization

Embodiment Construction

[0039] In order to make the object, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0040] figure 1 It is a schematic flowchart of the implementation method of the cognitive radio provided in Embodiment 1, such as figure 1 shown, including the following steps:

[0041] S1. The user terminal acquires target TV service information, and uses the target TV service information to pre-download the target TV service before the playing time of the target TV service. Now more and more user terminals such as televisions and set-top boxes are equipped with storage devices with huge capacity, and these storage devices can be used to store t...

Abstract

The invention discloses a cognitive radio implementation method, medium, terminal and device. The method includes the following steps: a user terminal acquires target TV service information, and pre-downloads the target TV service before the playing time of the target TV service; the network The management terminal predicts and monitors the usage rate of the target broadcast frequency band corresponding to the target TV service at the broadcasting moment, and when the usage rate is lower than the preset threshold, releases the target broadcast frequency band and forms idle spectrum information. The present invention uses storage devices to pre-store non-real-time TV services that are repeatedly broadcast and meet user viewing preferences, thereby reducing the number of live viewers of non-real-time TV services, thereby reducing the usage rate of the corresponding broadcast frequency band. When the usage rate drops to the preset When it is below the threshold, the broadcast frequency band can be released to form an idle frequency band, which can not only enhance the user experience, but also reduce the cost of broadcasting TV programs and improve the efficiency of spectrum use and the energy efficiency of the entire system.

Description

【Technical field】 [0001] The present invention relates to the field of cognitive radio, and in particular to an implementation method, medium, terminal and device of cognitive radio. 【Background technique】 [0002] In recent years, wireless communication services have been growing rapidly all over the world, which makes available spectrum resources for wireless communication become more and more scarce, and the problem of lack of spectrum resources is also becoming more and more serious. In the case of limited wireless spectrum resources, how to maximize the use of existing spectrum resources and improve spectrum utilization has become an urgent problem to be solved. According to some survey reports, the utilization rate of the VHF and UHF licensed frequency bands originally used for TV broadcasting is very low, and they are often idle. Spectrum (hereinafter referred to as white spectrum), specifically includes spectrum not allocated by the administrator, spectrum allocated...
