Abstract: The invention concerns a system for receiving by a gNB a location information sent by a GNSS chipset comprised in a mobile equipment, the location information being part of a signalling message as part of an initial access procedure, before network dedicated signaling ciphering setup procedure occurs, the GNSS chipset returning to the mobile equipment the location information concealed by a crypto scheme that does not need any diversification from one chipset to another, the concealed location information being de-concealed by a deciphering server at the level of the gNB by a reversed crypto scheme that does not need any diversification from one chipset to another for sending the location information in clear to a dedicated 5G core network, the dedicated 5G core network being the one able to handle a communication with the mobile equipment.
