A method is provided that creates signaling climate data records (CDR) via and a mobile communication system on a network, in order to charge signaling messages sent by user equipment (UE). The invention proposes two embodiments of the method for creating signaling CDR where an MME which has received signaling messages from UE notifies a PGW with a signaling CDR creation function of the message reception, and the PGW creates the signaling CDR. The MME can charge for the signaling message transmitted from the UE, without the additional components.
