MOBILE COMMUNICATION TERMINAL
First Claim
1. A mobile communication terminal connectable to access points, comprising:
- a first section which scans the access points to search for a targeted access point when activated and senses strength of signals received from the access points while scanning, wherein the first section is activated periodically;
a second section which performs radio communication after the targeted access point is detected by means of the scanning by the first section; and
a controller which specifies the home access point as the targeted access point upon identifying that the mobile communication terminal is out of a service area of the targeted access point from the signal strength sensed by the first section, and supplies the second section with power after the home access point is detected by means of the scanning.

Abstract
According to one embodiment, a mobile communication terminal comprises a first section which scans the access points to search for a targeted access point when activated and senses strength of signals received from the access points while scanning, wherein the first section is activated periodically, a second section which performs radio communication after the targeted access point is detected by means of the scanning by the first section, and a controller which specifies the home access point as the targeted access point upon identifying that the mobile communication terminal is out of a service area of the targeted access point from the signal strength sensed by the first section, and supplies the second section with power after the home access point is detected by means of the scanning.

8. A mobile communication terminal having a WLAN communication section and a controller, the WLAN communication section comprising:
-
a scan target access point storing section which stores a scan target access point data; and an access point scanning section which scans the access point based on the scan target access point data in the scan target access point storing section, and the controller comprising; a home access point storing section which stores a home access point data for automatic activation; an automatic activation controller which directs the WLAN communication section to scan; an access point list storing section which stores an access point; an access point in connection storing section which, in case of a successful connection to an access point, stores the access point data; a manual connection controller which writes the access point data in the access point list storing section into the scan target access point storing section so as to direct the WLAN communication section to scan, the manual connection controller being adapted for registering a connected access point data in the access point in connection storing section; a scan target access point controller which writes the home access point data in the home access point storing section into the scan target access point storing section while no WLAN communication is being performed, the scan target access point controller being adapted for writing the access point in the access point data in connection saving section into the scan target access point storing section while WLAN communication is being performed. - View Dependent Claims (10)

9. A mobile communication terminal having a WLAN communication section and a controller, the WLAN communication section comprising:
-
a scan target access point storing section which stores a scan target access point data; an access point scanning section which scans the access point stored in the scan target access point storing section so as to detect the access point; and a received electric field strength measuring section which measures received electric field strength of a transmitted wave from an access point, and outputs a received electric field strength signal to the scan target access point storing section, and the controller comprising; a home access point storing section which stores a home access point data for automatic activation; an automatic activation controller which directs the WLAN communication section to scan; an access point list storing section which stores an access point; an access point in connection storing section which, in case of a successful connection to an access point, stores the access point data; a timer which produces a timing signal for setting the mobile communication terminal to a suspend state of low power consumption every certain period of time; a scan target access point controller which is activated by the timer every certain period of time, the scan target access point controller being adapted for writing the home access point data in the home access point storing section into the scan target access point storing section upon the received electric field strength signal being in an in-service-area state for an identification threshold, the scan target access point controller being adapted for writing the access point in the access point data in connection storing section into the scan target access point storing section upon the received electric field strength signal being in an out-of-service-area state for the identification threshold. - View Dependent Claims (11, 12)
