Abstract
The overall throughput of the radio communication traffic in a radio communication area in a radio communication environment where a plurality of types of radio communication systems are mixedly used in a neighboring radio communication area is improved. When a multi-mode control station (101) performs communication with a terminal station in a network through a plurality of types of communication systems, a communication link parameter collecting section (10141) collects parameters indicating the states of the communication links. A resource allocation determining section (10143) determines communication resource allocation for which the throughput is the greatest for each resource allocation period according to the parameters. A communication control section (1015) controls a multi-mode communication unit (1012) according to the result of the determination.
