摘要： 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 an estimate of that brightest signal is subtracted from 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.

摘要： 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. Thereafter, the model is compared with the terminal section and the set of signal parameters including the time offset estimates is refined to minimize the difference between the model and the terminal section. The time offsets in the refined parameter set used to minimize the difference between said model and the terminal section, are adopted as the estimated time offsets between the first section and the terminal section and between the second section and the terminal section.

摘要： 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.

摘要： 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.

摘要： 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.
