Dynamic frequency hopping access method and apparatus

Abstract

An embodiment of the invention discloses a dynamic frequency hopping access method and apparatus which can detect idle channel. When detected idle channel is occupied by identification user apparatus, usable frequency congregation composed of said idle channel is determined, and channel is selected from said usable frequency congregation for composing frequency hopping congregation. The frequency hopping list is generated according with said frequency hopping congregation, and frequency hopping communication is processed according with channel of said frequency hopping list applied to said frequency hopping congregation. When detected idle channel is full idle channel, fixed frequency can be processed by using detected full idle channel. The method and apparatus can reduce cost of system access, and increase system safety obviously at the same time reducing access collision, and has better access fairness; so access effectiveness can be increase, also user satisfaction degree can be increase obviously.

Description

technical field [0001] The present invention relates to the field of cognitive wireless communication, in particular to a dynamic frequency hopping access method and device. Background technique [0002] The basic starting point of the current cognitive wireless communication is: in order to improve the spectrum utilization, the wireless communication user equipment with cognitive function can work in the authorized frequency band according to a certain "Opportunistic Way". Of course, this must be established when the licensed frequency band is not used or there is only very little communication traffic active. The available spectrum resources in the space, time and frequency domains are called "spectrum holes". The core idea of ​​cognitive wireless communication is to enable wireless communication user equipment to discover and reasonably utilize the "spectrum holes". ability. [0003] At present, a solution for cognitive wireless communication is proposed for the situati...

AI Technical Summary

Problems solved by technology

This access method must rely on the same control center in the entire network, so there will be problems in the coordination between BSs in different networks; and, because the access of new BSs depends on the BSs that have occupied channels in the system, there are new Possibility of BS being unable to access for a long time

[0006] From the above, it can be seen that whether it is to reduce the effective communication time or the possibility that the new BS cannot be accessed for a long time, the access effectiveness of the currently applied frequency hopping access method is very low, which seriously reduces user satisfaction.
