Abstract: Methods and systems for detection of venue walk-in events by consumers in possession of wireless mobile devices. Received signal strength indication (RSSI) information is received from a plurality of wireless base stations. The RSSI information relates to mobile devices that communicate with the wireless base stations. Based on the RSSI information, it is determined whether a venue walk-in event has occurred for a particular mobile device.

Abstract: System and methods for determining a relationship between an application-level identifier and a network-level identifier are provided. In one implementation, a discovery server receives a data request that includes an application-level identifier and a transitory network-level identifier. Based on the transitory network-level identifier, the discovery server determines a stable network-level identifier, and further maps the application-level identifier to the stable network-level identifier.

Abstract: Methods and systems for providing situational user contexts to mobile applications, allowing for delivery of the relevant content without exposing mobile users' locations and other personal data. A plurality of space-time contexts (STCs) are stored in computer memory, with each STC representing a situational environment as a function of location and time. A mobile user device is associated with at least one of the STCs based on, for example, the location of the device and the current time. The associated STCs are provided to an application interested in delivering context-specific data to the user of the mobile user device.
