Abstract: Systems, methods, and processor-readable storage media are disclosed for collecting information pertaining to the configuration of one or more wireless networks and using this information in turn to estimate the location of mobile wireless devices associated with those networks. Certain embodiments of the present disclosure are directed to providing efficient systems and methods for collecting the information, which are responsive to the coverage or quality of the wireless network configuration information already stored in a network database.

Abstract: Methods and systems of updating a zone profile comprising obtaining a plurality of radio signal parameter measurements and, if the plurality of radio signal parameter measurements contains at least one measurement corresponding to a dominant element of the zone profile and if the plurality of radio signal parameter measurements contains at least one measurement corresponding to a candidate element (e.g., statistically unlikely element) of the zone profile, updating the profile by either adjusting an existing parameter value or by adding a new element to the zone profile corresponding to the candidate element.

Abstract: 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.

Abstract: Disclosed is a method and system for managing inconsistencies between a radio communications network and a network database. In one aspect, the system is informed of one or more inconsistencies and various decisions are made as to what actions to take. One possible action is to simply inform a network operator of the discrepancy. Another possible action is to determine which network elements are affected by the inconsistency and to update the network database in relation to those network elements to compensate for the inconsistency.

Abstract: A method of calculating the position or state of motion of one or more terminals is proposed in which each has a receiver capable of making measurements of signals received from one or more transmission sources for use in calculating the unknown position or state of motion of the or each terminal. At least one transmission source has a known directional transmission pattern, and the bearing from one of the receivers of the or each of the transmission source having a known directional transmission pattern is estimated. Weights are assigned to the measurements made by the one receiver, the weights being calculated from the bearing or bearings and the known directional transmission pattern of the transmission sources.

Abstract: A method and system for determining whether a mobile radio terminal is in or out of a zone in a radio communications network by relying at least partially on a serving cell identity. The method provides for generating a profile representative of the zone using measurements taken by the mobile radio terminal, the network, and/or using predicted values. A comparison is then made to determine whether the mobile radio terminal is in or out of the zone.

Abstract: A mobile radio communications network is disclosed in which zones may be defined for provision of location based services and applications. Various methods are also disclosed for using the defined zones in different ways for different applications. The methods include associating users with zones, updating users of zones with changes to the zones, controlling zone size and dynamically uploading zone profiles to users based on the user's geographical location.

Abstract: The present invention sets out to overcome the hearability problem in CDMA communications networks in which positioning services are provided, by using a separate sampling device 204, 205, 206 for each transmitter 201, 202, 203, which sends to the computing device 208 a representation of the signals transmitted only by that transmitter. A cross-correlation of the representation sent back by the mobile terminal 207 with the representation sent back by the sampling device in the brightest transmitter is performed in the computing device 208, and a blurred estimate of that brightest signal is subtracted from a blurred version of the representation sent back by the mobile terminal 207 in order to reduce its effect on the remaining signals as far as possible. The cross-correlation and subtraction steps are iterated until no useful signals remain to be extracted.

Abstract: The invention provides a method of estimating the time offsets between signals transmitted by plural transmitters of a communications network and received by a receiver attached to a terminal. In the method a section of a representation of the signals from the plural transmitters received by the receiver at the terminal (a “terminal section”) is created as are a first section of a representation of the signal transmitted by a first of said transmitters and a second section of a representation of the signal transmitted by a second of said transmitters. Each of the first and second sections overlaps in time with the terminal section. Using the first section, the second section and a set of signal parameters, including initial estimates of the time offsets between the first section and the terminal section and between the second section and the terminal section, a model of a section of a representation of the composite signal received by the receiver from the first and second transmitters is created.
