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:
Disclosed is a method for locating a mobile radio unit within a mobile radio communications network. The method provides for the calculation of network variables such as a Real Time Difference (RTD) between network elements, from measurements already available to the network from, for example, handovers between network elements. The method provides for the location of radio mobile units without having to synchronise network elements such as BTSs or LMUs.

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.
摘要:
A method and system is disclosed for locating a mobile radio terminal in a radio communications network. The method makes use of additional positional constraints provided as a result of unreported cells. In one form of the invention, a likely reason for a particular cell not being reported is determined and an associated probability term is determined for use in a position location model. The invention also relates to a system for implementing the method.
摘要:
A method and apparatus for finding a radio terminal (10) in a radio communications network. The method includes making observations of attributes of radio signals associated with the radio terminal (10) and generating a route for a seeker (20) to find the radio terminal (10), based on the observations and estimated error distributions of those observations. The route may be displayed over a topographical map to guide the seeker to the target.

Methods, systems, processor-readable media, and devices 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 are disclosed. Also disclosed are methods, systems, processor-readable media, and devices for discovering and/or maintaining wireless transmitter characteristics corresponding to one or more wireless networks. Also disclosed are methods, systems, processor-readable media, and devices for aggregating wireless network transmitter characteristics from a plurality of wireless network transmitters. The present disclosure can be used across multiple networks, without requiring information from the operators of those networks, in which the information concerning those networks is collected and maintained in a current state efficiently and with rapid response to changes in the network configuration.
摘要:
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.
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 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.
