A mobile communication system (200) managing a tethering service comprises: a tethering service terminal (210) requesting a data service; a packet gateway device (240) included in a mobile communication core network, transmitting target packets corresponding to the request to the internet and receiving response data for the request from the internet (10); and a packet analysis device (260) identifying whether the target packets are the packets requested by the tethering service terminal or a parasitic terminal tethered to the tethering service terminal based on an IMEI value of the tethering service terminal included in the RADIUS account record.
