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.

A signal analysis system matches a mobile device cellular identifier to a mobile device network identifier. The system obtains multiple cellular positioning records (CPRs) and multiple network positioning records (NPRs). These records include different types of information because they are generated by different types of networks. The system performs spatial matching and temporal matching of the CPRs and the NPRs to identify a specific mobile device cellular identifier among the CPRs that belongs to a mobile device identified by a specific mobile device network interface identifier among the NPRs.

A method and system for disabling functions of a movement detection enabled device is provided. The method includes monitoring a movement detection signal of the movement detection enabled device in a vehicle and determining that the vehicle is currently in motion. An electronic tag in the vehicle is detected and instructions associated with the movement detection enabled device are retrieved. It is determined that the movement detection enabled device is located within a specified proximity to a driver location of the vehicle and that a user of the device is a driver of the vehicle. In response, specified functions of the movement detection enabled device are disabled.

Disclosed are devices, systems and methods for combining observations obtained at two different mobile devices attached to a human user for performing a navigation operation. For example, observations of a signal acquired at a first mobile device may be selected for computing a position fix based, at least in part, on a utility indicator associated with the observations.

The present disclosure provides a method for determining a real-time position of a mobile device using a global positioning system (GPS) and wireless local area network (WLAN) hybrid positioning mode. The method includes determining, by a mobile device, the mobile device's environment area based on GPS satellite signals; determining an absolute position of the mobile device based on the GPS satellite signals while the mobile device is moving from an outdoor area to an indoor area; estimating a reference position of the mobile device based on the determined absolute position and WLAN access point signals while moving to a shadow area; and while moving to an indoor area, determining an estimated position of the mobile device based on calculated regressive coefficients and the WLAN access point signals, and updating the estimated position of the mobile device based on motion information and indoor floor map information.

Techniques for watching a location of a device with respect to a destination target include obtaining a current location of a device from a localization operation, calculating an interval, and performing a next localization operation after the interval has expired. The interval may be calculated based on a velocity and a distance from the current location to a destination target. The techniques may also include calculating a displacement distance from the current location and adjusting the interval based on the displacement distance to thereby adjust a time for performing the next localization operation. The techniques may include performing state detection to determine a motion state of the device and performing the next localization operation based on the determined motion state.

A technique to determine whether a mobile device is in a substantially stationary state or a substantially moving state (e.g., with respect to a geo-fence in which the device may be within). These states are possible motion states associated with the mobile device. Preferably, the determination leverages a data table that includes a defined set of states (either substantially stationary, substantially moving or no change) associated with various transitions of the mobile device from, on the one hand, a last reported activity and, on the other hand, a currently-determined probable activity. Preferably, the new motion state is the substantially stationary state when the probable activity is relatively slower than last-reported activity, irrespective of whether the mobile device is in true motion. On the other hand, the new motion state is the substantially moving state when the probable activity is relatively faster than the last-reported activity.
