Problems solved by technology

[0004] As a supplement and modification to the traditional radio spectrum management method, the dynamic spectrum management system based on cognitive radio technology needs to reallocate frequency bands, so the dynamic spectrum management center must know the spectrum usage status at a certain location at a certain moment, And in order to know the usage status of the spectrum, it is necessary to have a spectrum detection device at the corresponding time and corresponding place. If there is a de

Embodiment Construction

[0044] Now in conjunction with the description of the drawings, the structure of the database, data processing, and query methods are described in detail.

[0045] 1. The design of each sub-library in the database.

[0046] see figure 1 , the dynamic spectrum management system includes a frequency usage database, a dynamic spectrum management center and a spectrum detection module. The role of the database is to provide services for the dynamic spectrum management center to reallocate frequency bands. To this end, the database structure includes eight interrelated sub-libraries, namely "spectrum original use status sub-library", "spectrum overall use status sub-library", "query sub-library", "hole analysis sub-library", "hole level Marking sub-library", "Original Spectrum Statistics Sub-library", "Overall Spectrum Statistics Sub-library", and "Power Gradient Sub-library". The purpose and working principle of each sub-library are as follows:

Abstract

The related database fit to dynamic frequency spectrum management comprises: a sub-database for initial state of the spectrum, a sub-database for entire state, a query sub-database, an analysis sub-database for cavity, a sub-database for cavity level label, a statistic sub-database for initial spectrum, an entire statistic sub-database, and a power gradient factor sub-database. This invention provides lots of query methods according to user request, and convenient to manage and maintain.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a database and a data query method supporting dynamic spectrum management, which are used for spectrum management and hole query by a dynamic spectrum management center. Background technique [0002] Cognitive Radio (Cognitive Radio) is a new concept that appeared internationally in the 1990s. A research focus of this technology is the perception and utilization of the wireless environment, and realizes the dynamic reuse of frequency bands already allocated to users and idle frequency bands, thereby improving spectrum utilization. [0003] The existing wireless spectrum management rules adopt a single-purpose spectrum allocation scheme, that is, when the radio spectrum management department allocates a certain frequency band to a certain business, it can only be used by the business; further, a certain frequency band is allocated to a certain If there is a wireles...
