基于虚拟数据库技术的频谱网格数据库访问和集成

Spectrum Grid Database Access and Integration on Virtual Database Technology

随着无线电设备种类和数量的增加,无线电频谱管理在社会生产和生活方面起着越来越重要的作用。但是由于历史及地区发展的不平衡性造成了我国目前各地区的频谱管理系统相对独立,极大的制约了我国频谱管理技术的发展,造成了资源的浪费及不必要的重复建设。在时现有频谱管理系统特点分析的基础上,提出一种在网格环境下的基于虚拟数据库技术的频谱数据库的访问和集成方法,并给出虚拟数据库的构建策略、频谱数据库资源注册和查询映射方法,为资源使用者提供了访问频谱数据库的一致访问接口。

With the development of wireless communication technology,the management of wireless spectrum is more important in our daily life, The interdepartmental management systems of spectrum can not cooperate and intercommunicate because of area and other reasons. Based on the analysis of the characteristics of the present spectrum management systems,a spectrum grid database access and integration based on virtual database technology is presented in this paper. It also includes the ways of database registering and query mapping to the virtual database based on the above virtual database mechanism.
