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...

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The dynamic frequency hopping access method provided by the embodiment of the present invention includes: performing idle channel detection, and when the detected idle channel is only occupied by the cognitive user equipment, determining an available frequency set composed of the idle channel, and selecting the available frequency set from the idle channel. Channels are selected from the available frequency sets to form a frequency hopping frequency set, and then a frequency hopping sequence is generated according to the frequency hopping frequency set, and the channels in the frequency hopping frequency set are applied to perform frequency hopping communication according to the frequency hopping sequence.

[0025] The dynamic frequency hopping access device provided by the embodiment of the present invention includes a connected frequenc...
