Abstract: A method used by an electronic device receiving a geo-fence service, determines whether a current position of the electronic device, determined using a cellular positioning system (CPS), is located within a first distance from a central point of a geo-fence service area. In response to determining that the current position is located within the first distance, the current position is determined using a Wi-Fi positioning system (WPS) and it is further determined whether the WPS determined current position is located within a second distance from the central point of the geo-fence service area. In response to the determination the current position is located within the second distance, it is determined whether the current position calculated using a global positioning system (GPS), is located within a boundary of a geo-fence service area.
