Patent ID: 8625536

Claim:
A communication system comprising a radio terminal, a plurality of radio base stations configured to perform radio communication with the radio terminal, and a communication control device controlling the plurality of radio base stations, in which logical communication paths are established between the radio terminal and the communication control device through each of the radio base stations, wherein the communication control device includes: a collector configured to collect, for each of the radio base stations, a state of use of the logical communication paths passing through the radio base station; and a state-of-use transmitter configured to transmit, to the plurality of radio base stations, the state of use of the logical communication paths passing through each of the radio base stations collected for the radio base station by the collector, wherein the state-of-use transmitter transmits, to the plurality of radio base stations, information on the radio base station of which the number of unused logical communication paths passing therethrough among the logical communication paths passing through the radio base station is not larger than the predetermined number, and each of the radio base stations includes: a state-of-use receiver configured to receive the state of use of the logical communication paths passing through each of the radio base stations from the communication control device, wherein the state-of-use receiver receives, from the communication controller, the information on the radio base station of which the number of unused logical communication paths passing therethrough among the logical communication paths passing through the radio base station is not larger than the predetermined number; and a selection controller configured to perform a control to determine the radio base station to which the radio terminal is to be connected based on the state of use of the logical communication paths passing through each of the radio base stations received by the state-of-use receiver, and wherein the selection controller performs a control to select, as a connection destination of the radio terminal, a radio base station other than the radio base station of which the number of unused logical communication paths passing through the radio base station among the logical communication paths passing therethrough is not larger than a predetermined number.
