Abstract:
Detection of a faulty radio oscillator is provided herein. Also provided herein is detection of faulty mobile timing measurements. Timing measurements, as observed by a mobile device, and an identification of primary scrambling codes associated with the timing measurements are captured. The primary scrambling codes match each timing measurement with a particular radio. The mobile device can also report its location information. Radios for which timing measurements have been received are paired. Based on the paired radios and an associated observed time delay derived from the timing measurements, comparisons can be made between paired radios having at least one common radio. Radios exhibiting an expected timing value can be removed from the analysis in order to isolate a radio that has a faulty radio oscillator.
Abstract:
Determining referenced based location information for a wireless radio network is described. Referenced based location information can include determining location reference information and corresponding location offset information based on location information. In an aspect, location information can be timed fingerprint location information. Location offset information can be communicated in a wireless network at a lower operational cost than the associated location information. As such, use of referenced based location information for a wireless network can reduce bandwidth consumption as compared to location information communicated at similar intervals. This is particularly true in large wireless networks. Moreover, the use of referenced based location information for determining timed fingerprint location information can be highly attractive in light of timed fingerprint location information facilitating location information for many non-GPS enabled devices and being associated with significant increases in the frequency and density of location event requests.
Abstract:
The disclosed subject matter provides for selecting a radio access technology resource based on historical data related to the radio access technology resource. Location information can be employed to determine a radio access technology resource. Historical information related to the radio access technology resource can then be employed to determine the suitability of the radio access technology resource. A set of radio access technology resources can be ordered or ranked to allow selection of a suitable radio access technology resource from the set. Incorporation of historical information can provide for additional metrics in the selection of a radio access technology resource over simple contemporaneous radio access technology resource information. In some embodiments timed fingerprint location (TFL) information can be employed to determine a location.
Abstract:
Assisted global positioning system (AGPS) information is retrieved from mobile devices and employed to facilitate antenna location. Measurement information, including AGPS information, can be received from a plurality of mobile devices dispersed over a geographical region. The measurement information can include location and timing information for the plurality of mobile devices. A timing difference between co-located antennas of a base station associated with the plurality of mobile devices can be computed. The location of the co-located antennas can be determined based on evaluating errors resultant from estimations based on a plurality of test locations. The measurement information can be aggregated over time and can be employed to update the antenna locations.

Abstract:
Site location determination using crowd sourced propagation delay and location data is provided. A propagation delay component receives a set of propagation delay measurements for communications between a mobile device and an access point. A user equipment location component receives a location of the mobile device, and a combination component combines the set of propagation delay measurements and the location into a set of location data. An access point location component determines a set of intersecting locations between the set of location data and additional sets of location data, and determines a location of the access point based on the set of intersecting locations.
Abstract:
Determining levels of geographic redundancy among radios of a wireless radio network is described. The level of geographic redundancy for a radio can affect the determination of location information for a user equipment (UE) on the wireless radio network. The disclosed subject matter can be employed in conjunction with timed fingerprint location (TFL) technologies to facilitate selection of radios employed in determining time values for TFL location determination. Levels of geographic redundancy can be employed to rank or order radios of a wireless radio network so as to reduce the likelihood of using geographically redundant radios in location determination. Further, rules can be selected to adjust threshold values and equations employed in determining the levels of geographic redundancy. Moreover, rules can be selected to apply boundary conditions to reduce the number of determinations formed for a set of radios of the wireless radio network.

Abstract:
Providing for improved network event tagging for mobile communications is described herein. By way of example, a mobile network can be configured to take periodic geographic positions of a mobile terminal operating within the mobile network. Network events occurring between the periodic geographic positions, otherwise partially unknown in position, can be estimated by referencing topographical information and estimating a route of travel of the mobile device. Estimated speed of the mobile device can be utilized to place the mobile device on a road network, cycling route, pedestrian walkway, or the like, and refine the estimated position of the mobile device at the time of the network event. Such estimates can be refined from traffic information or other real-time travel data. An estimated position of the mobile device can be output as an approximation of the network event to facilitate event modeling for the mobile network.
Abstract:
Adaptive calibration of measurements for a wireless radio network is described. A network location system can employ timed fingerprint location technology to determine location information for UEs in a NELOS enabled wireless network environment. Calibration of observed time measurements can reduce errors in determining location information. Adaptive calibration facilitates the selection of subsets of wireless network radios for calibration updates. The selection of wireless network radios comprising the subsets can be based on prioritization rules including prioritization based on historical calibration information, geographic information, or observation density information for a wireless network radio. Further, a wireless network radio can be deprioritized based on the availability of alternate location information related to the wireless network radio.
