Abstract:
A system for the control of a cellular radiocommunications network for radiocommunications with mobile stations (MS), said cellular network comprising at least one mobile switching center (MSC) enabling the interconnection of the cellular network with a public switched telephone network (PSTN), at least one base station controller (BSC) being connected to each mobile switching center (MSC), at least one base transceiver station (BTS) being connected to each base station controller (BSC), each base transceiver station (BTS) being associated with a geographical cell, said cellular network having various types of interfaces capable of being observed, wherein said control system comprises:fixed means for the recording and time-stamping of signalling information travelling through at least one interface among said various types of interfaces capable of being observed, in order to obtain recorded and time-stamped signalling information;fixed means for the centralization of the recorded and time-stamped signalling information;means for obtaining and time-stamping localization information concerning place(s) where said at least one interface is effectively observed, in order to obtain time-stamped localization information; andmeans for the association of said time-stamped localization information with said recorded and time-stamped signalling information so as to precisely localize segments of said cellular network located downline from each interface on which signalling information is recorded.
