Abstract
A method and an apparatus for controlling a WLAN scanning period using a velocity sensor in a mobile communication terminal are provided. The velocity of a user is measured at a predetermined period and it is determined whether the measured velocity satisfies a predetermined condition for changing the scanning period. A scanning period corresponding to the velocity is detected in a look-up table, if the velocity satisfies the predetermined condition. Scanning is performed at the detected scanning period.
Claims6
A method of controlling a scanning period using a velocity sensor in a mobile communication terminal, comprising the steps of:
- measuring, by a velocity sensor, a velocity of the mobile communication terminal;
- determining, by a controller, whether the measured velocity is greater than a threshold velocity;
- scanning at a default scanning period, if the velocity is not greater than the threshold velocity;
- identifying, by the controller, a scanning period corresponding to the velocity in a look-up table, if the velocity is greater than the threshold velocity;
- and
- scanning, by the controller, a neighboring access point of a wireless local area network at the identified scanning period.
A mobile communication terminal for controlling a scanning period using a velocity sensor comprising:
- a memory for storing a look-up table;
- and
- a controller for measuring a velocity of the mobile communication terminal, determining whether the measured velocity is greater than a threshold velocity, scanning at a default scanning period, if the velocity is not greater than the threshold velocity, identifying a scanning period corresponding to the velocity in the look-up table, if the velocity is greater than the threshold velocity, and scanning a neighboring access point of a wireless local area network at the identified scanning period.
