Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a computer-implemented method for displaying a heat map are provided. One of the methods includes: receiving heat data from a server, wherein the heat data comprises a color value associated with each of a plurality of regions and one or more geographic locations respectively corresponding to one or more boundary points of each of one or more heat regions among the plurality of regions; generating a first heat map comprising a plurality of pixels; obtaining a second heat map by adjusting the color value of each pixel in the first heat map; and providing the second heat map for display, wherein the second heat is superimposed on a digital map. This method addresses the issue of conventional techniques that service request information may be misrepresented due to abrupt changes in color values across neighboring heat regions.

Systems and methods for inherent fast Time To First position Fix (TTFF) and high sensitivity are described. An embodiment of a method may include interpolating a satellite position in response to a navigation message having initial conditions for satellite ephemeris data converted into Keplerian format, wherein signal fixation is maintained in response to receiving the navigation signal at least once per day.

Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to provide cradle insensitive inertial navigation. An example method for determining alignment changes between a first body frame and a second body frame according to the disclosure includes obtaining one or more images from an image capture device associated with the first body frame in response to detecting a change in alignment between the first body frame and the second body frame, determining a compensation information based on an analysis of the one or more images, and determining a position based on one or more inertial sensors and the compensation information.

In embodiments of sync feedback for time to first fix (TTFF), satellite data signals are received from which a geographic position of a positioning-system device can be determined. The satellite data signals each include a time reference and ephemeris data that indicates an orbital position of a satellite. A sync feedback is generated that includes a time-free position fix determined from a satellite data signal before bit sync and/or frame sync of the satellite data signal are obtained. The sync feedback is then utilized as a feedback input to determine the bit sync and/or the frame sync of the satellite data signal.

Systems, methods, and devices for inter-network service selection are described herein. Through the use of one or more of device identifiers and device classes, information including a randomization metric can be transmitted to networked devices indicating which devices and/or device classes are permitted or denied to access a given network service. Equipment seeking access may alter the selection based on this information. Equipment providing access may enforce access request based on this information. As an example, selection between eHRPD and LTE may be load balanced based on device class or identifiers.

Systems and methods for inter-network service selection

In a method of implementing a positioning system a buffer is configured to store a buffer record for each of a plurality of position fixes determined by the receiver and a database is configured to store a database record for each of the position fixes. Buffer records are accumulated, with each buffer record corresponding to one of the position fixes determined by the receiver. A first threshold position near an area in which a degradation event occurs is identified and recorded in a first database record. A second threshold position near the area is identified in a second database record. The second threshold position is indicated by one of the position fixes outside of the area and is proximate to a position at which the degradation event ends.

A system for determining a position of a device, the system including a receiver module, a communication module, and a location determining module. The receiver module respectively acquires signals from a plurality of satellites totaling in number less than five. The communication module obtains, from a server, via a cellular network or a wireless network, ephemeris data corresponding to one or more of the plurality of satellites. The location determining module determines the position of the device based, at least in part, on (i) the signals acquired from the plurality of satellites, and (ii) the ephemeris data corresponding to the one or more of the plurality of satellites obtained from the server. The position of the device is further determined without a priori knowledge regarding the position of the device.

A circuit switched (CS) paging message is received at a multi-mode communication device. The CS paging message is received when a packet switched (PS) service is active at the multi-mode communication device. A PS precedence feature is activated at the multi-mode communication device that prioritizes PS communications over CS communications. A CS bearer connection is established with a CS network in response to receiving the CS paging message, and an incoming call notification message that identifies a calling party is received from the CS network. Upon receipt of the incoming call notification message, the CS bearer connection with the CS network is released. A notification of a missed incoming call from the calling party is displayed (e.g., substantially in real-time) via a user interface.

A method, an apparatus, and a computer program product for wireless communication are provided in which 1&#xd7;CSFB for communication of SMS messages in an LTE environment may be avoided. An IWS may receive a paging request message from a MSC, wherein the paging request message includes a first SMS service option indicating communication of a SMS message using a first RAT. The IWS may avoid an ESR procedure by analyzing the first SMS service option in the paging request message. Further the IWS may establish a common channel connection between the IWS and a target UE using a second RAT, wherein the first RAT and the second RAT are different.

Method and apparatus for enabling common channel communications of SMS

Provided herein are methods and systems for efficient communication between a server and a client in an assisted navigation system. In one or more embodiments, the server transmits a set of parameters for a satellite to the client, e.g., a GPS receiver, via a wireless or wired connection. The set of parameters includes a force parameter, initial condition parameters and time correction coefficients for the satellite. The receiver uses the received parameters in a numerical integration to compute the position of the satellite at a desired time. The set of parameters needed for the integration is small. To further reduce the amount of data transmitted, reference parameters may be subtracted from the original parameters before transmission from the server. The receiver is able to reconstruct the original parameters from the received parameters and the identically computed reference parameters. The parameters may be further compressed using data compression techniques.
