摘要： Systems and techniques for determining the location of user equipment (UE) in a wireless network are disclosed. These techniques leverage geometric calculations for an overlaid bin grid framework mapping the wireless network area to store differential values for each frame of the bin grid framework for each pair of relevant NodeBs. A timing offset can be determined, such that when a time value from a target UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the target UE time value can be search for in the pre-computed differential value data set indexed by a relevant NodeB site pair to return a set of frames (forming a hyperbola between the site pair) that can be intersected with a second set of frames for a second NodeB site pair for the same UE. The intersecting frames can represent the location of the UE in the wireless network. Further, the data can be leveraged to correct timing in the network.

摘要： The present disclosure provides devices, systems, and methods to utilize relative timing offset information reported by one or more mobile devices. When coupled with AGPS information reported by one or more mobile devices, the offset information is be used to calibrate calculations and subsequently to locate all 3G mobiles with GPS-like accuracy, whether or not a GPS receiver is available on said mobile device being located. A determination of a propagation delay between one or more cell sites and a mobile device is reported to a network and used to calibrate unknown information such as a timing offset, to improve the accuracy of a detected location. The relative timing offset can be applied to determine a location for all other mobile devices within the area served by the known base station. The present disclosure utilizes this method in conjunction with information crowd-sourced from a plurality of mobile devices.

摘要： Scrambling code conflicts can be mitigated by primary scrambling code reuse that minimizing a potential interference Primary scrambling codes are applied to a first set of cells located in a portion of the network being considered. A second set of cells are evaluated for primary scrambling code reuse based on a distance parameter and/or a coverage area. If the distance parameter is greater than a defined distance, primary scrambling code reuse can be applied. If all distance parameters evaluated are less than the distance parameter, a length of the distance parameter is reduced and the distance between cells is reevaluated.

摘要： 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.

摘要： A user equipment (UE) location in a wireless network can be determined by leveraging geometric calculations for an overlaid bin grid framework mapping the wireless network area to store differential values for each frame of the bin grid framework for each pair of relevant NodeBs. A timing offset can be determined, such that when a time value from a target UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the time value from an idle-state target UE can be accessed. The target UE time value can be searched among pre-computed differential value data sets indexed by relevant NodeB site pairs to return sets of frames that can facilitate converging on a location for the target UE. Intersecting frames can represent the geographic location of the UE in the wireless network. Further, the data can be leveraged to correct timing in the network.
