WIFI AND GSM LANDMARKS AND NEIGHBORHOODS FOR LOCATION BASED SERVICES
First Claim
1. A method of delivering location-based information to a mobile device, comprising:
- collecting visible cellular telephone base site information at the mobile device;
collecting visible local wireless site information at the mobile device;
formatting the cellular telephone and local wireless information into a location signature;
sending the location signature from the mobile device to an information service; and
receiving location-based application data corresponding to the location signature.

Abstract
A system for capturing and delivering location-based information and services captures wireless landmark information sent by mobile devices to build a map of locations based on the relationship between wireless landmarks that are visible to the mobile device at the same time. A wireless landmark may be a cellular telephone base site or local network (WiFi/Bluetooth) access point. The mobile device may capture a location signature using identifiers for all wireless local area networks in range as well as one or more cellular telephone transmitters. A location service resolves the location signature into a relative location that an application service may use to record incoming information or to send location-specific information such as traveler comments, reviews, or advertisements. The distance between two mobile devices may be calculated using weighted edge values, representing a number of ‘hops’ between location signatures.

9. A system supporting location-based application data delivery to a mobile device, the system comprising:
-
a mobile device including; wireless hardware that collects visible wireless system identification information for at least two network types; a processing capability that forms a location signature from the wireless system identification information for the at least two network types; a transceiver for sending a current location signature; and a user interface for delivering location-oriented information; a location service that maps location signature information and matches the current location signature to a location; and an application service that uses the location to deliver location-oriented information to the mobile device. - View Dependent Claims (10, 11, 12, 13, 14, 16, 17, 18, 19)

15. A method of operating a location service comprising:
-
receiving location signatures generated by a plurality of mobile devices, each location signature including wireless landmark information for at least one cellular telephone site and at least one local network site; assigning an edge value to a pair of wireless landmarks received in the same location signature; generating a map of wireless landmarks using landmark pairs received in the same location signature and using edge values to determine logical distances between cellular telephone sites and location network sites; receiving a first location signature from a mobile device; returning a map location including logical distances from a plurality of wireless landmarks for use in accessing location-related information.
