Abstract: A handover method in a mobile wireless network is provided to transmit a fast binding update message by a new access router after a mobile node is accessed to the new access router, thereby providing a seamless service while minimizing processing delay due to handover. A mobile node requests information required for handover by a PAR(Previous Access Router). The mobile node transmits an FBU(Fast Binding Update) message to a new access router(305). The new access router delivers a packet to the mobile node(309). The mobile node releases connection between the second layer and the previous access router(310).

Abstract: A method and an apparatus for receiving communication data are provided to realize continuous satellite communication without additional satellite communication repeaters by receiving data at an NLOS(None Line Of Sight) through a mobile communication network. An apparatus(400) for interacting wireless networks comprises a satellite communication gateway(402), a mobile communication gateway(404), a connection control unit(406), a wireless connection gateway(408) and a wireless connection device(409). The apparatus supports the IPv4(Internet Protocol Version 4) and IPv6, and performs a subnet management function. The satellite communication gateway converts satellite digital communication data signals into a signal format which is able to be used in the apparatus. The mobile communication gateway converts the data signals of the wireless LAN(Local Area Network) or Wibro(Wireless Broadband) into a signal format which is able to be used in the apparatus. The connection control unit analyzes the data signals received from the satellite communication gateway, and controls the mobile communication gateway so that the mobile communication gateway can receive the data signals, if the level of the signals is lower than a reference level. The wireless connection gateway converts the signals received from the connection control device into a signal format which is suitable for an AP(Access Point) within a mobile terminal. The wireless connection device outputs the converted signals to the AP within the mobile terminal.

Abstract: An apparatus for improving traffic processing performance in consideration of QoS in a bi-directional satellite connection system and traffic security, and its security method are provided to guarantee QoS by classifying traffic of each service and requesting a central station to allocate resources of a return link according to each service. An SMT(Satellite Mobile Terminal) PEP(Performance Enhancement Proxy) server receives an IP packet from a user terminal and stores it, transfers a reception response signal with respect to the IP packet to the user terminal by proxy for a central station, inserts traffic type information previously stored in a TCP(Transmission Control Protocol) header into an IP header of the IP packet before the IP packet is encoded, and re-transmits an IP packet, for which a reception response signal has not received, according to a re-transmission request from the central station. An SMT VPN(Virtual Private Network) server encodes an IP payload excluding the IP header of the IP packet from the SMT PEP server. A traffic classifier classifies the encoded IP packet according to traffic type information by using the inserted traffic type information. A data transmission/reception processing unit requests the central station to allocate resources of a return link with respect to the classified IP packet according to a priority level of each traffic type.
