摘要:
Systems, methods, and processor readable media for estimating the speed of a mobile radio terminal traveling on at least one road segment are disclosed. Certain embodiments are characterized by determining one or more routes through a road network that a mobile radio terminal could have traveled based on a sequence of wireless measurements from the mobile radio terminal. In addition, systems, methods, and processor readable media for collecting and transmitting radio communications network measurements from a mobile terminal for use in a system of estimating a traffic flow speed on road segments are disclosed. Certain embodiments are characterized by accumulating and communicating a plurality of wireless measurements to a traffic flow measurement server such that reporting of wireless measurements is minimized when the mobile radio terminal is stationary.

A computer-implemented mobile device calling method is provided. The method includes detecting initiation of a communication between a first mobile device and a second mobile device and determining a current location of the first mobile device in response to initiation of the communication between the first mobile device and the second mobile device. The method further includes transmitting the current location of the first mobile device to the second mobile device in response to initiation of the communication between the first mobile device and the second mobile device. A system for managing distribution of location information between mobile devices is further provided.

A method for obtaining a local path loss versus range model in a radio communications network is disclosed. The method comprises obtaining at least one path loss measurement and an associated range measurement at an approximated location of a mobile radio terminal within the radio communications network and applying this to a path loss versus range model to obtain the local path loss versus range model. The local model may also be used to obtain a more accurate location of the mobile radio terminal within the radio communications network.
摘要:
System for providing alert-based communication services for which corresponding alert conditions to be met by mobile stations are defined. The system includes an alert engine capable of firing alerts associated with the alert-based communication services if location data regarding the mobile stations is indicative of the mobile stations meeting the alert conditions corresponding to the alert-based communication services. A requirements engine determines an expected earliest future time at which at least one alert condition is capable of being met by a particular mobile station and outputs a data element indicative of a requirement to obtain updated location data about the particular mobile station in advance of the expected earliest future time. A scheduler receives expiry times data and processes the expiry times data for determining an order for servicing the location requests.
摘要:
A computer-implemented mobile device locating method is provided. The method includes determining a current cell sector of a mobile device and comparing the current cell sector with a cell sector list of previously determined cell sectors. A current location of the mobile device is determined if the current cell sector is not listed in the cell sector list. The current location is compared with a last determined location. The current cell sector is added to the cell sector list if the current location is substantially the same as the last determined location. The cell sector list is cleared if the current location is not substantially the same as the last determined location.
摘要:
A computer implemented method is provided for resolving eventual consistency conflicts when using a Prefix Hash Tree (“PHT”) and Distributed Hash Table (“DHT”). A prefix hash tree having multiple nodes is created that relates to a distributed hash table. The nodes comprise leaf nodes and internal nodes. All distinct records are aggregated across all conflicting nodes, wherein conflicting nodes are nodes that have identical data records. Records returned are counted. If the count of aggregated records exceeds a max record count, nodes are split such that the aggregated records are divided by a prefix into each new node resulting in the consolidation of duplicate data that were in conflicting nodes into a single data record in a single node. If one or more of the returned conflicting nodes is an internal node, the internal node is split regardless of the number of aggregated records.

摘要:
A computer-implemented method for processing mobile device location data is provided. Location data is filtered based on age and accuracy or precision of location coordinates. Location data is partitioned based on the location coordinates into a plurality of clusters including a plurality of location data instances. The plurality of clusters are filtered based on a number of data instances in a particular cluster and a period of time over which data instances of the particular data cluster are generated. A distance is determined from a location coordinate corresponding to the data instances of one or more of the plurality of clusters to a particular predetermined location, and the one or more of the plurality of clusters are correlated with the particular predetermined location in response to the distance being less than a predetermined distance. The invention further provides a location data processing system.

A computer-implemented method for preventing communication using a mobile communication device is provided. The method includes enabling a motion detection process and detecting with the motion detection process at a first instance the mobile device is in motion. The motion detection process is disabled in response to detecting the mobile device is in motion. An attempted communication is detected via the mobile device, and the motion detection process is re-enabled in response to detecting the attempted communication. The method further includes detecting with the motion detection process at a second instance if the mobile device is in motion. If the mobile device is detected at the second instance in motion, the attempted communication is disabled. If the mobile device is detected at the second instance not in motion, the attempted communication is enabled.
