  • Patent number: 9448306
    Abstract: 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.

  • Patent number: 9389317
    Abstract: 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.

  • Patent number: 9319853
    Abstract: 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.

  • Publication number: 20150327137
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided which enable dissimilar radio access networks to exchange loading information that may be used to determine reselection criteria for mobile terminals and/or classes of mobile terminals. A network entity in one network, aware of loading conditions in another network, can determine whether a wireless terminal should attempt to reselect the other network. The method comprises receiving information related to the operational status of a first network at a second network, and determining at the second network whether to direct an idle user equipment in the second network to reselect the first network based on the operational status of the first network. The first and second networks may employ different radio access technologies.

  • Patent number: 8665150
    Abstract: 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.

  • Patent number: 8639274
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which 1×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.

  • Patent number: 8635016
    Abstract: 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.

  • Publication number: 20130232555
    Abstract: 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.

    Abstract: The present invention is related to location positioning systems, and more particularly, to a method and apparatus for providing reliable extended ephemeris information and indicators of quality. According to one aspect, the invention employs a concept of Approximate Accuracy Symmetry, in which a history of broadcast ephemerides is logged for each satellite, and used as a reference to evaluate the potential accuracy of the predicted orbit for each satellite in the future. According to further aspects, the desired accuracy information for the extended ephemerides can be reliably provided in advance.
