Two electronic devices automatically perform a synchronization session when one of the electronic devices is brought in proximity to the other electronic device. The synchronization session is initiated without user intervention based simply on the fact that the two devices have recently been brought within a predetermined distance of each other. The two electronic devices communicate in a wireless manner. The two devices may determine that they are within a predetermined distance of each other using global positioning technology, via which one of the devices determines its own position and compares it to a known position of the other electronic device. Alternatively, one of the electronic devices may output a low level signal that can be received by the other electronic device when within a certain range. Once the low level signal is received, the recipient of the low level signal outputs a stronger signal to ensure that it is received by the other electronic device requesting a synchronization session, which once established enables synchronization of information between the two devices.

An Application Program Interface (API) is defined at a requesting terminal. The API provides a common interface between an application program requesting a location for a target mobile terminal and a location server at the requesting terminal. The location server may be integrated into the API or may be a separate entity. The application program executing on the requesting terminal sends a request through the API for the location of the target mobile terminal. Thus, the API hides the positioning technology details and complexities from the requesting application program. The API communicates with a location determining source that determines the location of the target mobile terminal. The location determining source may be the target mobile terminal. Alternatively, the location determining source may be a network location server such as a Gateway Mobile Location Center or Mobile Positioning Center.
