Abstract
A method for determining a location of a mobile apparatus based on the presence of wireless access point signals. The received wireless signal strength from a plurality of observed wireless access points is compared with profiles each relevant to a different user context and containing a plurality of previously registered wireless access point signal strengths around a previously registered location. The location of the mobile apparatus is determined based on the profile most closely matching the collection of observed wireless access points. Wireless access points present in the profile but not observed are ignoring during the matching process.
