摘要： A method implemented by an assisted Global Navigation Satellite System (GNSS) server determines a position of a GNSS receiver. The method includes sending a request for measurement information to the GNSS receiver at a first time and receiving the measurement information from the GNSS receiver in response to the request at a second time, where the measurement information includes position measurement data and a corresponding measured time based on satellite signals received by the GNSS receiver. The measured time is determined to be erroneous when it is outside an accurate time range determined based on at least one of the first time and the second time. A substitute time is identified and the position of the GNSS receiver is determined based on the substitute time when the measured time is erroneous.

摘要： A method implemented by a proxy server is provided for routing requests for a Location-to-Service Translation (LoST) service without traversing a forest node structure. The method includes receiving a request for the LoST service initiated by a client, the request including a location of a user device and a requested service; identifying an authoritative LoST server configured to service the requested service and bounded by a service boundary that includes the location included in the request; and directly forwarding the request to the identified authoritative LoST server, without routing through any other LoST server.

摘要： A system method for estimating Global Navigation Satellite System assistance data in a communications network. The method may comprise transmitting a location request from a mobility management entity to a location server, requesting a wireless device to transmit a first signal, and transmitting the first signal by the wireless device. A path delay estimate between the wireless device and location server may be determined as a function of an elapsed time for the request to the wireless to be received and as a function of an elapsed time for the transmitted first signal to be received. Satellite assistance data may then be determined as a function of current network time and the determined path delay estimate.

摘要： A method of providing a location of a target device includes receiving a first location reference request from the target device at a first location server, generating a first location reference in response to the first request, and including the first location reference in a second location reference request to a second location server. The second location server generates a second location reference in response to the second request, where the second location reference is stateless and refers to the first location reference. The second location reference is received from the second location server, and provided to the target device to be provided to an application requesting location information of the target device from the second location server. The stateless second location reference includes information necessary for the second location server to serve a request for the location of the target device without maintaining state specific to the location reference.

摘要： A system and method for determining the location of a target device. A location request may be received for a target device, and a plurality of parameters determined that identify the target device. A most likely path may be selected from a plurality of paths to produce a location of the target device, each path having one or more of the plural determined parameters as an input and one or more measurement results as an output. Measurement information may be collected on the most likely path as a function of one or more of the determined parameters to provide the one or more measurement results. Location information may then be derived for the target device as a function of the one or more measurement results, the derivation utilizing a location determination function that evaluates ones of the plural paths. An estimated location of the target device may then be determined as a function of the respective location information for the selected path.
