Patent Images
1. A method of controlling a scanning period using a velocity sensor in a mobile communication terminal, comprising the steps of:
- measuring a velocity of the mobile communication terminal;
determining whether the measured velocity is greater than a threshold velocity;
identifying a scanning period corresponding to the velocity in a 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.

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.
