1. A communication device comprising:
- a data acquisition unit that acquires, by using a processor, sensed data related to a signal receiving condition in a spectrum assigned to a first communication service;
a determination unit that determines, by using a processor, which of a first area inside a service area of the first communication service where a signal receiving condition is suitable, a second area inside or in a peripheral part of the service area where a signal receiving condition is not suitable and a third area outside the service area the communication device is located based on the sensed data acquired by the data acquisition unit, wherein the determination unit determines whether the communication device is located in the first area or not based on a signal level of a received signal in the spectrum, and the determination unit further determines that the communication device is located in the third area when a control channel or an uplink signal of the first communication service is not detected; and
a secondary usage starting unit that starts, by using a processor, usage of a second communication service using a part or whole of the spectrum assigned to the first communication service by a procedure different depending on a kind of the area where the communication device is located determined by the determination unit.

8. A communication control method comprising the steps of:
-
acquiring sensed data related to a signal receiving condition in a spectrum assigned to a first communication service; determining which of a first area inside a service area of the first communication service where a signal receiving condition is suitable, a second area inside or in a peripheral part of the service area where a signal receiving condition is not suitable and a third area outside the service area a communication device is located based on the acquired sensed data; determining whether the communication device is located in the first area or not based on a signal level of a received signal in the spectrum; determining that the communication device is located in the third area when a control channel or an uplink signal of the first communication service is not detected; and starting usage of a second communication service using a part or whole of the spectrum assigned to the first communication service by a procedure different depending on a kind of the area where the communication device is located. - View Dependent Claims (14, 15, 16, 17, 18)
