PROBLEM TO BE SOLVED: To provide a mobile communication system in which a channel utility efficiency is more improved and the cost of a mobile station is reduced. SOLUTION: A mobile communication system 1 divides a service area by plural basic cells BC where a base station BS is arranged respectively in the plural basic cells BC and is composed so that communication is attained between the base station BS and a mobile station MT in the basic cells BC to which each of the base station BS belongs. In this case, a micro cell 4 is formed by combining basic cells whose the number corresponds to a mobile speed of the mobile station MT including the basic cell BC to which the mobile station MT belongs and is composed so that communication is attained between at least one of the base station BS in the micro cell 4 and the mobile station MT. |
