Method for selecting base station
First Claim
1. A connection control method for selecting one base station, to which a terminal is to connect, from a plurality of base stations in a wireless communication system, said connection control method comprising:
- a first step of obtaining an index of communication quality between the terminal and the base stations for each of said plurality of base stations wherein, said plurality of base stations being classified into a plurality of groups;
a second step of calculating characterizing quantities of the communication quality for each of the groups; and
a third step of specifying one of the plurality of groups based on the charactering quantities and selecting one of base stations, which belong to the specified group, as a connection destination base station of said terminal.

Abstract
When one base station to which a terminal is to connect is determined from a plurality of base stations in a wireless communication system, the best base station is selected according to the communication quality or the content of communication services. In the wireless communication system, the plurality of base stations are classified into a plurality of groups. Indexes of communication quality between the base stations and the terminal are obtained and, for each group, the characterizing quantities of the indexes of communication quality are calculated. The base station group with which the terminal is to communicate is specified based on the characterizing quantities. One of the base stations in the specified group is determined as a communication destination base station.
