Abstract
The methods, apparatus, systems and computer program products provide for sensing a magnetic field, emitted by a short-range communication source, to activate short-range communication modules in a mobile terminal. In addition to sensing the magnetic field, the terminal may rely on other parameters, such as operational state of the terminal, contextual information and the like, to determine if the short-range communication module should be activated. As such, the invention reduces the overall power consumption of the terminal by limiting the active state of the short-range communication module. By conserving power the mobile terminal is capable of operating for longer periods of time without requiring charging or replacement of the power supply.
