1. A method of searching for an access point of a local area network in an electronic device, the method comprising:
- determining a moving level of the electronic device;
searching for an access point of the local area network according to a result of the determination on the moving level of the electronic device;
measuring an amount of change in signal strength of the access point; and
determining whether or not to access the access point according to the moving level of the electronic device and the amount of the change in the signal strength of the access point,wherein the determining of the moving level of the electronic device comprises;
identifying the moving level of the electronic device by using position information of the electronic device, which is measured through at least one of a sensor or a GPS module in the electronic device, a Doppler frequency change of a serving cell of the electronic device, a change in a strength of a signal that is received from one or more nearby cells of the electronic device, a change in a strength of a signal that is received from a base station of a mobile communication network, or a change in the number of nearby cells of the electronic device; and
comparing the identified moving level with a first reference value to then determine that the moving level of the electronic device is high if the identified moving level is equal to, or more than, the first reference value and to then determine that the moving level of the electronic device is low if the identified moving level is less than the first reference value.

7. An electronic device comprising:
-
a local area communication module that searches for one or more access points of a local area network and performs wireless local area communication; a controller that determines a moving level of the electronic device, searches for an access point of the local area communication module according to a result of the determination on the moving level, measures an amount of change in signal strength of the access point, and determines whether or not to access the access point according to the moving level of the electronic device and the amount of the change in the signal strength of the access point; and a mobile communication module that performs mobile communication, wherein the controller;
identifies a Doppler frequency change of a serving cell of the electronic device, a change in a strength of a signal that is received from one or more nearby cells of the electronic device, a change in a strength of a signal that is received from a base station of the mobile communication network, or a change in the number of nearby cells of the electronic device by using a signal that is received through the mobile communication module;
identifies the moving level of the electronic device by using the identified change; and
compares the identified moving level with a first reference value to then determine that the moving level of the electronic device is high if the identified moving level is equal to, or more than, the first reference value and to then determine that the moving level of the electronic device is low if the identified moving level is less than the first reference value. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
