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: A resource allocation method for mobility of a terminal station in a satellite system is provided to seamlessly provide a service regardless of a movement area of a terminal station. When a terminal station enters a satellite network shadow area from a non-shadow area(202), the terminal station is connected to a terrestrial network(204). The terminal station continuously provides an Internet service which has been provided in the non-shadow area by using resources of the terrestrial network(206). When the terminal station moves from the shadow area to a non-shadow area(208), it requests resources from a resource manager of a central station through the terrestrial network which has a response speed faster than that of the satellite network(210). The terminal station is allocated the requested resources from the central station(212). The terminal station is connected to the satellite network with the allocated resources to perform communication via the satellite network, and as the terminal station uses the resources, it is disconnected from the terrestrial network(214).
