The first timing advance measurement is indicative of a measurement based on one or more signals of a first serving cell. A a second timing advance measurement is also obtained. The second timing advance measurement is indicative of a measurement based on one or more signals of a second serving cell. A location estimate is determined based at least partially on the first timing advance measurement and the second timing advance measurement.

A computer is programmed to receive, via a vehicle wireless receiver, a wireless signal from a mobile device, and determine a presence of the mobile device within a distance of the vehicle. The computer is programmed to classify a movement of the mobile device based at least on the determined device presence, and actuate a vehicle component based on the determined device presence and the classified movement of the mobile device.

A method is described of using the mobile device so as to control the drain of power from the power source of the mobile device, the mobile device having at least two location determination techniques having respective power drain characteristics, the method includes selecting the location determination technique having a lower power drain characteristic the greater the determined distance of the mobile device from a predetermined location or area, and selecting the location determination technique having the greater power drain characteristic the smaller the determined distance of the mobile device from a predetermined location or area. The method thus uses the least accurate technique when furthest away and the most accurate technique when closer to a predetermined location or area.

Method for providing positioning data in a positioning node of a radio network, which positioning data is associated with a mobile device including a radio unit, the method comprising the steps of establishing a radio session for receiving positioning data in the positioning node from the radio unit; transmitting report control data to the radio unit, wherein the report control data identifies a request to report positioning data obtained in the device, wherein said positioning data includes inertial measurement data; and receiving positioning data from the radio unit in accordance with the report control data.

A first communication node and method therein for activation of a positioning procedure for a target device in a wireless communication network are disclosed. The first communication node determines whether the target device has moved and activates a positioning procedure for the target device when the movement is larger than a threshold.

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 method, apparatus and computer readable storage medium determine the position of a mobile device. Position data items are collected that indicate if the mobile device was located in a vicinity of a predetermined public transportation building when the respective position parameter was captured. Motion data items are also collected that represent a respective motion parameter captured by the mobile device within the vicinity of the predetermined public transportation building. Based on the positioning data item(s), the motion data item(s) and/or public transportation data, it is determined if the mobile device has left the vicinity of the predetermined public transportation building on board a public transportation vehicle and/or has arrived at the vicinity of the predetermined public transportation building on board a public transportation vehicle and, if so, the motion data item(s) are associated with a boarding or waiting and/or arrival area for passengers of the public transportation vehicle.

The invention relates to navigation, particularly, to detection of indoor and outdoor positions of mobile devices. Technical result of the invention is to improve the accuracy of mobile terminal position detection at time of occurrence of a specific trigger event and decrease of load on sensor, computing, communication and other resources of the mobile terminal at times when a trigger event occurs. Mobile terminal positioning technique at the trigger event moment, is characterized by the following sequence: receipt of series of readings of inertial and non-inertial sensors, identification of intervals, during which readings of at least one sensor generates a stationary process; then detection of at least one point of time, when at least one stationary process is replaced by another stationary process; then identification of parameters of at least one pattern of movement for at least one stationarity interval; then detection of at least one position of the mobile terminal according to readings of non-inertial sensors; estimation of mobile terminal path according to parameters of at least one pattern of movement and then of position corresponding to change of one stationary process to another; then detection of mobile terminal position at time corresponding to a specific trigger event.
