Abstract
A wireless communication interface measures a signal level of a received signal from an access point. A control unit calculates connection time with the access point to which a mobile communication device is connected. The control unit associates a first connection threshold or a second connection threshold that is larger than the first connection threshold with the access point on the basis of the connection time. After calculating the connection time, when the mobile communication device is not connected to the access point, the control unit determines whether to connect the mobile communication device to the access point on the basis of a comparison between the signal level and the first connection threshold or the second connection threshold associated with the access point.

A mobile communication device comprising:
- a wireless communication interface configured to measure a signal level of a received signal from an access point;
- and
- a processor configured to perform a procedure including:
- calculating a connection time period during which the mobile communication device has been connected to the access point,
- associating a first signal level threshold with the access point when the connection time period is above a time threshold, and associating a second signal level threshold that is larger than the first signal level threshold with the access point when the connection time period is equal to or less than the time threshold,
- determining, after calculating the connection time period, when the mobile communication device is not connected to the access point, whether to connect the mobile communication device to the access point on the basis of a comparison between the measured signal level and the first signal level threshold or the second signal level threshold associated with the access point, and
- connecting the mobile communication device to the access point when the determining determines to connect to the access point.
A wireless communication method comprising:
- calculating, by a processor included in a mobile communication device, a connection time period during which the mobile communication device has been connected to an access point;

- determining, by the processor, after calculating the connection time period, when the mobile communication device is not connected to the access point, whether to connect the mobile communication device to the access point on the basis of a comparison between a measured signal level of a received signal from the access point and the first signal level threshold or the second signal level threshold associated with the access point;
- and
- connecting the mobile communication device to the access point when the determining determines to connect to the access point.
