Mobile communication device and communication control method

A mobile communication device, comprising:

• a first antenna;
• a second antenna;
• a communication unit, which performs a communication that includes transmitting or receiving a signal by using at least one of the first antenna or the second antenna, and which intermittently receives a signal based on an intermittent reception cycle that is variable by using one of the first antenna or the second antenna;
• an analyzing unit that analyzes a communication quality of the first antenna based on information on a signal that is continuously received by way of the communication unit by using the first antenna;
• and
• a control unit that controls the communication cycle during communications performed by the first antenna by lengthening the intermittent reception cycle of the second antenna for receiving a signal intermittently, in a case in which a measured communication quality of the first antenna as analyzed by the analyzing unit is higher than a predetermined communication quality level, the first antenna being used to continuously transmit or receive the signal during which time the second antenna maintains an intermittent cycle, wherein the first antenna is simultaneously receiving or transmitting a communication continuously, thereby maintaining a communication quality while suppressing power consumption.
