Abstract:
A method, in a mobile device, of controlling region determination by the mobile device, includes: determining a present pressure at the mobile device; determining, based on the present pressure and a reference pressure, that the mobile device moved from a first region to a second region within a structure, the first region and the second region being different regions of the structure and vertically displaced from each other; and performing region determination in response to determining that the mobile device moved from the first region to the second region.
Abstract:
Techniques are discussed herein for providing notification messages to a user are provided. An example method of providing an alert to a user in an environment with multiple devices includes determining a first notification device based at least in part on a location of the user and one or more notification preferences associated with the user, generating an alert message based at least in part on the first notification device, and sending the alert message to the first notification device.

Techniques for providing a notification to a user in a home network are provided. An example method according to the disclosure includes receiving an alert for the user, determining a location of the user, determining one or more proximate devices based on the location of the user, determining a location of one or more proximate non-interested users based on the proximate devices, determining an activity of the user, determining a preferred notification device based at least in part on the location of the user, the location of one or more proximate non-interested users, and the activity of the user, generating a notification message based at least in part on the preferred notification device, and sending the notification message to the preferred notification device.
Abstract:
Systems and methods for managing activities among collocated mobile devices include means for determining a set of tasks to be performed collectively by the two or more collocated mobile devices while collocated and during a period of time in the future, the two or more collocated devices being configured to communicate with one another; means for assigning a first task of the set of tasks to be performed by a first mobile device of the two or more collocated mobile devices; and means for assigning a second task of the set of tasks to be performed by a second mobile device of the two or more collocated mobile devices; wherein the first mobile device and the second mobile device are different from one another with regard to at least one subsystem, and are each capable of performing the first task and the second task.
Abstract:
A method of organizing positioning assistance data includes: determining that first access points are more likely to be used for determining a position of a mobile device than second access points, the first and second access points being members of a master group of access points, at least the first access points being access points from each of which at least one signal has been received by the mobile device; storing first sets of positioning assistance data, associated with the first access points, in a first cache; and storing second sets of positioning assistance data, associated with the second access points, in a second cache; where the first cache has a quicker access rate than the second cache.
Abstract:
Techniques for determining a position of a mobile device are provided. An example of these techniques is a method that includes performing a passive scan for wireless transceivers proximate to the mobile device to generate passive scan results, generating a first wireless transceiver list, comprising a first set of wireless transceivers, transmitting a request to at least one wireless transceiver from the first wireless transceiver list requesting that the at least one wireless transceiver perform a scan, generating a second wireless transceiver list comprising identifying information for a second set of wireless transceivers, proximate to the at least one wireless transceiver, measuring signals received from wireless transceivers selected from at least one of the first wireless transceiver list and the second wireless transceiver list, and determining the position of the mobile device based at least in part on the signals measured.
Abstract:
Methods and apparatus are described for providing location assistance information to a mobile device. An example of a method for providing location assistance information to the mobile device by a femto base station includes receiving a macro base station signal during a monitoring time period during which the femto base station is substantially stationary, obtaining location assistance information, the location assistance information being based, at least in part, on the received macro base station signal, and transmitting the location assistance information to the mobile device.
Abstract:
Systems, apparatus and methods for estimating a location of a mobile device are presented. Before computing a location estimate, the mobile device groups a plurality of access points into two or more categories (for example, a first list of access points having a first characteristic and a second list of access points having a second characteristic). Round-trip time (RTT) measurements are computed for access points in the first list. A Short Interframe Space (SIFS) value may be determined for each access point in the first list or generally SIFT representing the first list as a whole. The RTT measurements are compensated with the appropriate SIFS value. The mobile device then computes its location or position fix estimate using the compensated RTT values while excluding less accurate RTT values from other access points. As a result, the location estimate eliminates adverse influent from some access points.
