Abstract: A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of one or more structures within an environment, including a structure that is defined in the dataset as having at least a first surface. The data-processing system establishes a bounding box that is representative of the first surface and partitions at least a portion of the bounding box into a first set of tiles. The data-processing system then projects a first set of ray tubes from a predetermined point within the environment, to the tiles in the first set of tiles. Each ray tube in the first set of ray tubes is defined by a corresponding tile in the first set of tiles. The data-processing system evaluates the incidence of bounced ray tubes at a predetermined receive point within the environment and presents a propagation result that is based on the evaluated incidence.

Abstract: A technique for designing and testing drive-test plan for gathering location-dependent RF data is disclosed. In accordance with some embodiments of the present invention, one candidate drive-test plan is chosen for implementation over a second based on an economic cost-benefit analysis of both plans. This is in marked contrast to, for example, a selection of drive-test plans, or the design of a drive-test plan, based on a calibration-cost analysis, in which the data estimated to be the most effective to calibrate a radio-frequency tool is sought for a given cost or the least cost. Although a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis is a species of cost-benefit analyzes in general, it is not an economic cost-benefit analysis because a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis has deficiencies that an economic cost-benefit analysis does not.

Abstract: A telecommunications system is disclosed comprising a wireless switching center and plurality of base stations that are configured to transmit positioning reference signals. The base stations transmit the positioning reference signals in positioning subframe time intervals. Meanwhile, the base stations also transmit cell-specific reference signals continuously, including during the positioning subframe time intervals. In order to ensure that the wireless terminal measures those cell-specific reference signals during periods of lower interference, the base station imposes a measurement restriction on the wireless terminal, in regard to when it may measure a signal. As a result of utilizing the measurement restriction in this way, in combination with the improved interference characteristics of the positioning reference signals themselves, the ability of the wireless terminal to detect the cell-specific reference signals of more distant cells is improved. The improved signal measurements are then made available to functionalities such as location estimation.

Abstract: A technique for estimating the geo-location of a mobile station, based on signal measurements or other data that are obtained from both the control plane and the user plane. Through the coordination of obtaining signal measurements from both planes, the disclosed method and system make location estimations of greater accuracy possible. A data-processing system is configured to receive requests for location estimates from a location-based services (LBS) client or from a different source. The illustrative data-processing system then coordinates the acquisition of location data across both the control plane and the user plane, and correlates the data. The correlated location data can be subsequently used to generate a location estimate.

Abstract: A disclosed detector estimates the wireless terminal as being indoors or outdoors by utilizing information that includes measurement report data from previous calls involving both i) wireless terminals that are known to have been indoors and ii) wireless terminals that are known to have been outdoors while the measurement report data was collected. Based on this call data, one or more classification features are computed in accordance with the illustrative embodiment of the present invention. Then, for a wireless terminal that is to be classified during a call and with respect to the terminal being either indoors or outdoors, features that are representative of that wireless terminal for the call are evaluated against a characterization that is a composite of one or more previously-computed classification features. The features that are representative of the wireless terminal can be derived from the measurement reports received from the wireless terminal during the call.

Abstract: A technique is disclosed for estimating the location of a wireless terminal at an unknown location in a geographic region. The technique is based on a two-part recognition, the first part being that there are certain optical and acoustic characteristics that are present in some environments while not being present in others, such as lighting flicker and sound reverberation. The second part of the recognition is that a correlation exists between the presence of flicker and reverberation in the vicinity of a wireless terminal and whether the wireless terminal is indoors or not. Under certain environmental conditions, flicker and reverberation are often present indoors but not outdoors. By accounting for flicker and reverberation being detected or not being detected in the vicinity of the wireless terminal, the disclosed technique is able to estimate whether the wireless terminal is indoors, which the technique also uses to improve the location estimate.

Abstract: A technique for estimating the location of a wireless terminal at an unknown location in a geographic region is disclosed. The technique is based on the recognition that there are location-dependent traits of electromagnetic signals. In environments where multiple antennas are radiating the same signal, as in the case of distributed antennas or host-repeater configurations, one or more possible locations of the wireless terminal can be designated as improbable based on i) a measure of the propagation delay of a signal traveling between a) a base station and b) the wireless terminal or an infrastructure antenna, or ii) the maximum distance at which a signal is detectable by the wireless terminal. Additionally, the applicable set of values for the location-dependent traits is selected based on similar criteria.

Abstract: An illustrative system and method for detecting a wireless terminal in a wireless network by ascertaining information about the wireless terminal's location, thus enabling individualized surveillance and tracking of certain wireless terminals. In some embodiments, the detection is triggered by a signal that is compliant with the Customized Applications for Mobile networks Enhanced Logic (“CAMEL”) protocol. Several kinds of mobile-telecommunications events can trigger detection, including events that do not involve call origination. Advantages include bypassing the home location register when obtaining a location estimate for the wireless terminal and when determining whether a wireless terminal is of interest.
