Apparatus and method for reducing power consumption in portable terminal
First Claim
1. A mobile terminal for reducing power consumption, the mobile terminal comprising:
- a memory configured to store first information containing at least one position information of at least one AP and second information containing information of at least one AP that has previously been connected;
a wireless LAN module configured to perform a connection with an AP; and
a controller configured to control to;
determine whether the mobile terminal is currently positioned within a coverage of the stored at least one position information by comparing a current location of the mobile terminal with the stored at least one position informationactivate the wireless LAN module if the controller determines that the mobile terminal is currently positioned within the coverage;
perform connection with an AP having the coverage;
determine whether information of the connected AP having the coverage is included in the stored second information; and
add the information of the connected AP to the second information if the information of the connected AP having the coverage is not included in the stored second information, wherein the controller is configured to control the wireless LAN module to maintain the activated state if the mobile terminal is positioned outside of the stored coverage of the connected AP and the connection with the connected AP is maintained.

Abstract
An apparatus and method minimize power consumption in a portable terminal which enters a low-power mode during connection with an access point (AP). The apparatus includes a memory for storing a Wi-Fi profile including position information of APs, a wireless LAN module for performing connection with the AP, an AP connection unit for performing connection with the AP using the wireless LAN module only when an AP exists around the portable terminal, a position determining unit for determining APs which exist around the portable terminal, and a controller. The controller is configured to determine a position of the portable terminal, determine a position of an AP which exists around the portable terminal, and operate the wireless LAN module at only a position where the AP exists.

10. A method of reducing power consumption in a mobile terminal, the method comprising:
-
storing first information containing at least one position information of at least one AP and second information containing information of at least one AP that has previously been connected; determining whether the mobile terminal is currently positioned within a coverage of the stored at least one position information by comparing a current location of the mobile terminal with the stored at least one position information; activating the wireless LAN module if the controller determines that the mobile terminal is currently positioned within the coverage; performing connection with an AP having the coverage; determining whether information of the connected AP having the coverage is included in the stored second information; adding the information of the connected AP to the second information if the information of the connected AP having the coverage is not included in the stored second information; and controlling the wireless LAN module to maintain the activated state if the mobile terminal is positioned outside of the stored coverage of the connected AP and the connection with the connected AP is maintained. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A mobile terminal comprising:
-
a memory configured to store first information containing at least one position information relating to a predefined hot spot area of at least one AP and second information containing information of at least one AP that has previously been connected; a wireless LAN module configured to perform a connection with an AP; and a controller configured to control to; determine whether the mobile terminal is currently positioned within a predefined hot spot area of an AP by comparing a current location of the mobile terminal with the stored at least one position information activate the wireless LAN module if the controller determines that the mobile terminal is currently positioned within the hot spot area; perform connection with the AP having the hot spot area; determine whether information of the connected AP having the hot spot area is included in the stored second information; and add the information of the connected AP to the second information if the information of the connected AP is not included in the stored second information, wherein the controller is configured to control the wireless LAN module to maintain the activated state if the mobile terminal is positioned outside of the predefined hot spot area of the connected AP and the connection with the connected AP is maintained. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
