Abstract:
1. A method for locating a terminal in a local wireless telecommunications network performed at a locating system that provides a location estimation of the terminal depending on a set of configuration data and on a set of measuring data, wherein the network comprises a plurality of access points providing services on a plurality of coverage areas and the locating system is located remotely from the terminal and the plurality of access points, comprising: defining a set of configuration data comprising a plurality of configuration data base entries related to a configuration of the local wireless telecommunications network; acquiring a set of measuring data from the terminal or the network comprising a plurality of measuring data types, wherein each measuring data type depends on the type of terminal and the set of measuring data indicates whether the terminal belongs to a subset of said plurality of coverage areas; associating each of a plurality of locating procedures with a different combination of at least one of the plurality of configuration data base entries and at least one of the plurality of measuring data types, wherein each of the plurality of locating procedures is configured to estimate a position of the terminal based on the associated combination and corresponds to an accuracy value of the estimated position, each of said plurality of locating procedures having associated a respective weight index in terms of difficulty in providing said configuration data; and selectively actuating at least one of the plurality of locating procedures obtained from said associating step to provide the location estimation by taking into account said weight index and said accuracy value.
