Abstract
A method performed in connection with a handheld communication device for monitoring a context in a battery efficient manner and for detecting a vehicular motion context, the handheld communication device comprising a GPS hardware component, a network-based position estimation component and a data processor, the method comprising: acquiring a sequence of location data readings using the network-based position estimation component; identifying a non-vehicular motion context based on changes in the acquired sequence of the location data readings; if the non-vehicular motion context is identified, continuing to acquire the sequence of the location data readings; if the non-vehicular motion context is not identified, powering on the GPS hardware component and acquiring speed data using the GPS hardware component, determining whether the acquired speed is within predetermined vehicular speed ranges and identifying either a vehicular motion context or the non-vehicular motion context.
