20120310746 | LEARNED CONTEXT CORRELATION THROUGH NETWORK COMMUNICATION OBSERVATIONS - Establishing a correlation between a user's context and wireless signal observations from that context enables wireless computing devices to provide users with targeted information. Rather than performing an expensive calibration, mobile sensor data indicative of a user's context is bundled with wireless signal observations and transmitted to server computing devices that can obtain a context from the mobile sensor data, correlate that to the wireless signal observations, and store the same in a context/wireless correlations database. When other wireless computing devices request a context based on wireless signal observations made by those wireless computing devices, reference can be made to the database and a context correlated to those wireless signal observations is obtained and provided to them, enabling targeted information to be delivered to their users. To accommodate heterogeneity among wireless computing devices the database maintains correlations according to the wireless computing devices from which the data originated. | 12-06-2012 |
20120311328 | PROBE RESPONSE SUPPORTED WIRELESS AUTOCONNECTION - Computing devices can autoconnect to access points even if they have not previously received authentication information for those access points.

An access point receiving such a probe request generates a probe response that provides authentication information that the computing device can then utilize to establish a useful communication connection to the access point. The provided authentication information can be either encrypted or unencrypted, and can be encrypted for specific users or specific computing devices. Dedicated application programs can decrypt encrypted authentication information, thereby enabling autoconnecting, while also delivering targeted information to users of the autoconnecting computing devices from a retailer hosting the access point. Authentication information for a “landing page” can be provided to a web browser to enable autoconnection. | 12-06-2012 |
20120315901 | CENTRALIZED CONTEXT AWARENESS THROUGH NETWORK ASSOCIATION - A user's context is determined based on the wireless network to which the user is connected.

The providers also provide targeted information that they wish to have delivered to users whose context indicates that they are in or near that provider's store. The centralized mechanism further has information associating the wireless computing device with contact information that can be utilized to deliver targeted information. The targeted information can be delivered to the user via the wireless network, a cellular network or through other communicational mechanisms. The provider, or retail establishment, can also be informed of the presence of the user near its premises. | 12-13-2012 |
