An SMT(Satellite Mobile Terminal) performance improving proxy server(126) receives an IP(Internet Protocol) packet from a user terminal(128) and stores it, transfers a reception response signal with respect to the stored IP packet by executing as proxy for a central station(10), re-transmits an IP packet for which reception response signal has not been received in response to a re-transmission request from the central station(10), and inserts traffic type information previously stored in a TCP header into an IP header of the stored IP packet before the stored IP packet is encoded. An SMT virtual private network server(125) encodes an IP payload in which the IP header of the IP packet received from the SMT performance improving proxy server(126) is excluded. A traffic classifier classifies the coded IP packet according to the traffic type information. A transmission/reception processing unit(121) requests the central station to allocate resources of a return link with respect to the classified IP packet according to a priority level of a certain traffic type.
