    摘要: A method of determining a location of a measurement device includes determining, at a server: measurement times of first positioning signal measurements, of first positioning signals from first positioning signal sources and/or a subset of positioning signal sources of second positioning signal sources. The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.

    摘要: A method of verifying a device location includes receiving a provisional location for a first device, setting a baseline location confidence value for the provisional location, determining a first network environment of the first device, and receiving one or more location reports each including a location for another device in the first network environment. For each received location report, the location in the location report is compared with the provisional location of the first device and a distance is calculated; and an adjustment to the location confidence value of the first device is calculated based on the calculated distance. An output location confidence value is generated for the provisional location of the first device based on the baseline location confidence value and the adjustment calculated for each received location report.

    摘要: A data processing device (10) includes: a detection unit (11) that detects change points of a first data series including a first identifier and change points of a second data series including a second identifier; a calculation unit (12) that calculates an occurrence probability that the change points of the first data series and the change points of the second data series occur in synchronization with each other; an association unit (13) that associates the first identifier and the second identifier as identifiers related to a tracing target on the basis of the occurrence probability; and a determination unit (14) that determines a type of an identification target of the associated first or second identifier on the basis of the occurrence probability.

    摘要: The present disclosure provides details of a system and method for a communication device for guards in controlled environments. The communication device is established based on an indoor wireless infrastructure in the controlled environment, receiving wireless positioning signals to calculate and determine the real-time location of a user carrying the device. The indoor wireless positioning can be combined with other available positioning methods to provide highly accurate positioning information of the guard. The communication device detects, monitors, and records activities of the guard during a period of time, and is controlled by the control center. The control center and the communication device respond quickly to different abnormal situations. In addition, the communication device detects contraband electronic devices and monitor surroundings of the guard. Thus, the disclosed system and method for the communication device provides improved communication and monitoring for guards in a controlled environment.

    摘要: A positioning method relating to the field of communications technologies includes: a positioning device obtains a positioning parameter set and sends the positioning parameter set to a positioning center, where the positioning parameter set includes multipath information of a to-be-positioned terminal, and the multipath information is used to position the to-be-positioned terminal. The positioning center may position the to-be-positioned terminal by using the multipath information of the to-be-positioned terminal.
