WiFi and GSM landmarks and neighborhoods for location based services
First Claim
1. A system comprising:
- a mobile device configured to;
collect visible cellular telephone base site information at the mobile device;
collect visible local wireless site information at the mobile device;
format the visible cellular telephone base site information and the visible local wireless site information into a location signature;
send the location signature from the mobile device to an information service; and
receive 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.

12. A system comprising:
-
a location server configured to; receive location signatures generated by mobile devices, the location signatures including wireless landmark information for wireless landmarks including cellular telephone sites and local network sites; assign edge values to pairs of the wireless landmarks that are received together in the location signatures; generate a map of the wireless landmarks using the pairs of the wireless landmarks that are received together in the location signatures, the map being generated using the edge values to determine logical distances between the cellular telephone sites and the local network sites; receive a first location signature from a first one of the mobile devices; and return, to the first mobile device, a location reflecting first logical distances of the first mobile device from at least some of the wireless landmarks. - View Dependent Claims (13, 14, 15, 16)

17. A method comprising:
-
accessing cellular telephone base site information reflecting one or more cellular telephone base sites that are visible to a mobile device; accessing local wireless site information reflecting one or more local wireless sites that are visible to the mobile device; providing the cellular telephone base site information and the local wireless site information to a location service that determines a location of the mobile device based on the cellular telephone base site information and the local wireless site information; and processing location-based application data that is associated with the location of the mobile device determined by the location service. - View Dependent Claims (18, 19, 20)
