摘要： 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： Disclosed is a method and system for detecting inconsistencies between a radio communications network and a network database. In one form, measurements from the network are provided by mobile radio terminals. The measurements are then compared with corresponding data on the network database to determine whether there is an inconsistency. The methods described may be used in the management and maintenance of the network.

摘要： A method is disclosed for finding the position of a mobile radio-frequency transceiver in a communication system. A network of at least two unsynchronized base stations is arranged to transmit and receive signals to and from at least one mobile radio frequency transceiver. A reference receiver located at a known distance from the base stations measures the times of arrival of signals transmitted from the base stations. Using the known distances and measured times, a determination is made of the relative time offsets of transmission from each base station. The determined relative time offsets are used to calculate the position of the mobile transceiver in the network area using hyperbolic positioning techniques. A number of other enhancements including the use of Doppler, carrier information, and direction of arrival to improve the performance of mobile telephone-based positioning systems are also described.

摘要： The invention concerns a method of finding the position of a mobile radio-frequency transceiver in a communications system. A network of at least two unsynchronized base stations arranged to transmit/receive signals to at least one mobile-radio frequency transceiver; a reference receiver located at a known distance from the base stations and including measuring means to measure the times of arrival of signals transmitted from the base stations; determination means to use the known distances and measured times to determine the relative time offsets of transmissions from each base station; and location means to use the determined relative time offsets to calculate the position of a mobile transceiver in the network area using hyperbolic positioning techniques. A number of other enhancements to positioning systems relating to the usage of Doppler, carrier information, direction of arrival to improve the performance of mobile telephone-based positioning systems are also described.

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.

摘要： A bulkhead barrier member for separating a tubular member into chamber sections is described. The barrier member has a diameter between about 0.001 to 0.005 inches less than the diameter of the inner surface of the tubular member when positioned within the tubular housing. Upon compression of the barrier member, the barrier member is radially expandable to engage the inner surface of the tubular member to provide a sealed barrier between the chamber sections.
