A base station comprising: a first wireless communication unit adapted for communicating with mobile stations for offering a first radio communication service; and a second wireless communication unit adapted for communicating with mobile stations for offering a second radio communication service that is different from the first radio communication service; characterized by: a first abnormality detector (58, 60) adapted for detecting that the first radio communication service becomes not executable; a second abnormality detector (62, 64) adapted for detecting that the second radio communication service becomes not executable; and a communication service continuation restrictor adapted for restricting, based on an operation setting, when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable, operation of the base station as to whether or not the other one of the first and second radio communication services should be continued, wherein the operation setting is settable whether or not the communication service continuation restrictor should continue the other one of the first and second radio communication services when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable. a first wireless communication unit adapted for communicating with mobile stations for offering a first radio communication service; and a second wireless communication unit adapted for communicating with mobile stations for offering a second radio communication service that is different from the first radio communication service; characterized by: a first abnormality detector (58, 60) adapted for detecting that the first radio communication service becomes not executable; a second abnormality detector (62, 64) adapted for detecting that the second radio communication service becomes not executable; and a communication service continuation restrictor adapted for restricting, based on an operation setting, when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable, operation of the base station as to whether or not the other one of the first and second radio communication services should be continued, wherein the operation setting is settable whether or not the communication service continuation restrictor should continue the other one of the first and second radio communication services when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable. a first abnormality detector (58, 60) adapted for detecting that the first radio communication service becomes not executable; a second abnormality detector (62, 64) adapted for detecting that the second radio communication service becomes not executable; and a communication service continuation restrictor adapted for restricting, based on an operation setting, when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable, operation of the base station as to whether or not the other one of the first and second radio communication services should be continued, wherein the operation setting is settable whether or not the communication service continuation restrictor should continue the other one of the first and second radio communication services when the first (58, 60) or second (62, 64) abnormality detector has detected that either one of the first and second radio communication services becomes not executable.
