A base station has a first wireless communication unit that communicates with mobile stations for offering a first radio communication service to the mobile stations, and a second wireless communication unit that communicates with mobile stations for offering a second radio communication service that is different from the first radio communication service to the mobile stations. At the base station, a communication service continuation restrictor is provided that restricts operation of the base station as to whether or not, when it is detected that either one of the first or the second radio communication service is not executable, another radio communication service should be continued. Whether or not the other communication service should be continued can be set at the communication service continuation restrictor.
