一种动态频率选择方法、装置、基站及网络系统
摘要：
本发明公开了一种动态频率选择方法，包括获得候选信道信息后，根据获得的候选信道信息确定均衡各候选信道被选择的概率的候选信道等级；根据确定的候选信道等级更新候选信道选择概率；根据更新后的候选信道选择概率选定一个信道。本发明还公开了一种动态频率选择装置、基站及网络系统。使用本发明通过均衡各可用候选信道被选择的概率，减小了邻近认知系统在某一候选信道的接入碰撞率，从而减小了网络系统的最大时延，提高了网络系统的吞吐量。
摘要（英）：

The present invention provides a method of dynamic frequency selection, including acquiring candidate channel information, then determining and balancing a candidate channel level of the selected probability of each candidate channel according to the acquired candidate channel information; updating candidate channel selection probability according to determined candidate channel level; selecting a channel according to the updated candidate channel selection probability. The invention also provides a dynamic frequency selection device, base station and network system. By balancing the selected probability of each available candidate channel, the invention reduces the access collision rate of the adjacent cognitive system in a certain candidate channel, thereby reducing the maximum time relay of the network system, improving the throughput of the network system.
