通信システムの親局及びアクセス制御方法

Title:

通信システムの親局及びアクセス制御方法

Document Type and Number:

Japanese Patent JP4393514

Kind Code:

B2

Abstract:

A communication bandwidth is divided into a beacon period in which all master stations compete for transmission of a beacon packet, a first carrier sense multiple access (CSMA) period in which only authorized specific stations are allowed to compete for access, and a second CSMA period in which all stations are allowed to compete for access. The master stations exchange information with each other about a communication bandwidth being used in the first CSMA period, thereby calculating a communication bandwidth which can be used by each communication system in the first CSMA period, based on the information.
