Abstract
To eliminate the problems when a handover by a mobile station UE over a radio base station eNodeB is performed during a positioning process of the mobile station UE. A mobile management node MME according to the present invention is configured to transmit a transfer signal 'S1-AP Downlink NAS Transport' including an LPP signal received from a positioning calculation node E-SMLC and the identification information of the E-SMLC to a radio base station eNodeB, and when a transmission failure reason included in a transmission failure notification signal 'S1-AP NON DELIVERY INDICATION' received from the radio base station eNodeB indicates a positioning failure, the mobile management node MME transmits the transmission failure reason and the LPP signal included in the transmission failure notification signal “S1-AP NON DELIVERY INDICATION” to the positioning calculation node E-SMLC identified by the identification information of the E-SMLC included in the transmission failure notification signal.
