Wireless communication method and wireless communication apparatus

A wireless communication apparatus comprising:

• a transmitting/receiving unit capable of transmitting/receiving information through a first wireless communication system and a second wireless communication system;
• a receiving unit capable of receiving information through the first wireless communication system and the second wireless communication system and whose reception gain in the first wireless communication system is smaller than the transmitting/receiving unit;
• a switching unit which detects that a reception sensitivity of informative information notifying an incoming call by the transmitting/receiving unit through the first wireless communication system has exceeded a threshold when information is being transmitted/received by the transmitting/receiving unit through the second wireless communication system, and switches reception of the informative information from the transmitting/receiving unit to the receiving unit;
• and
• a threshold setting unit that sets the threshold in accordance with a reception gain difference between the transmitting/receiving unit and the receiving unit to a first threshold when the reception gain difference is large and to a second threshold when the reception gain difference is small.

• and
• a threshold setting unit that sets the threshold to a first threshold when the frequency used by the first wireless communication system and received by the transmitting/receiving unit is at a first frequency band and to a second threshold when the frequency is at a second frequency band.
