Abstract
A wireless mobile communication device includes a wireless communication subsystem configured to wirelessly communicate through a local data access point to cause a query to be delivered to a remote access point location database. The location database contains information about the location of local data access points within a widespread area. The query is for location information for data access points located near the wireless device. The wireless device receives nearby access point location information from the database, and the device causes at least a portion of the access point location information to be delivered to a user. This may be done through a user interface, upon request of the user, and while the wireless communication subsystem is not connected to a local data access point.
