System and method for sharing indoor location information with one or more application program modules within a portable computing device

摘要

A method and system for sharing indoor location information with one or more application program modules within a portable computing device (“PCD”) includes receiving an indoor location data request and determining if a location service is currently being executed by the PCD. If the location service is not being executed, it is determined if a location engine of the PCD has been installed. If the location engine of the portable computing device has not been installed, then the code for the location engine is downloaded from a communications network. Next, the location service may be executed once the location engine has been installed. It is determined if the indoor location data being requested is present in a memory element of the PCD. If the indoor location data being requested is not present in the memory element of the PCD, then the indoor location data is downloaded from the communications network.

1. A method for sharing indoor location information with one or more application program modules within a portable computing device, the method comprising:
receiving an indoor location data request; determining if a location service is currently being executed by the portable computing device; if the location service is not being executed, then determining if a location engine of the portable computing device has been installed; if the location engine of the portable computing device has not been installed, then downloading code for the location engine from a communications network; executing the location service once the location engine has been installed; determining if the indoor location data being requested is present in a memory element of the portable computing device; and if the indoor location data being requested is not present in the memory element of the portable computing device, then downloading the indoor location data from the communications network.
