Dynamic channel allocation method and dynamic channel allocation apparatus
First Claim
1. A dynamic channel allocation method for dynamically allocating a plurality of channels of a wireless communication network having a plurality of base station groups comprising base stations which do not mutually interfere with one another, wherein the dynamic channel allocation method comprises in each of the base stations:
- an informing step of informing channel information requesting for the use of a channel to adjacent base stations which mutually interfere with one another; and
a determination step of determining a channel to be used, in accordance with the priority of each base station group for the use of a channel, the priority being defined for each channel on the basis of the channel information of a base station and the channel information of the adjacent base stations.

Abstract
(1) Base stations are divided into base station groups which do not mutually interfere with one another. (2) Priorities of the use of channels are set for each base station group, and each base station holds a priority table showing the priorities of the use of channels. (3) Each base station derives a channel to request, and informs about the channel to adjacent base stations. (4) When the requested channel of the base station overlaps with a requested channel of the adjacent base station, each base station refers to the priority table and autonomously judges whether the requested channel can be used or not. Therefore, it is no longer necessary to wait for a response to the requested message or to confirm with the adjacent base stations regarding the availability of channels, and reduction of the throughputs and prompt channel allocation are possible.

19. A dynamic channel allocation apparatus for dynamically allocating a plurality of channels of a wireless communication network having a plurality of base station groups comprising base stations which do not mutually interfere with one another, the dynamic channel allocation apparatus comprising:
-
an informing portion which informs channel information requesting for use of a channel to adjacent base stations which interfere with one another;
a storage portion which stores a priority table defining the priority of each base station group for each channel; and
a use channel determination portion which determines a channel to be used in accordance with the priority table on the basis of the request channel information of the base station and of the adjacent base stations.
