    摘要: Provided are an apparatus for controlling handover between heterogeneous networks, a method of performing handover between heterogeneous networks in a mobile router, and a mobile router. The method includes determining whether a handover to a network employing a different method from a network to which the mobile router belongs is required based on information prestored in the mobile router, the network to which the mobile router belongs determined by current location information of the mobile router and performing the handover according to the result of the determination. Mobility detection time can be reduced by applying the handover technique between wireless/satellite networks based on link trigger and location to a mobile router moving at high speed. Thus, service interruption can be prevented regardless of movement speed, even in a satellite shadow region such as a station.

    摘要: Provided is a satellite network communication system based on Second Generation Digital Video Broad-casting via Satellite (DVB-S2). A method for encapsulating transmission data in a digital satellite communication system includes: determining whether a time at which a reference time information packet has to be inserted into a packet data unit is arrived, in the digital satellite communication system; and if the time at which the reference time information packet has to be inserted into the packet data unit is arrived, transforming the packet data unit in the form of a baseband data packet including the reference time information packet. Therefore, by allowing transmission of Network Clock Reference (NCR) information in a satellite communication environment based on Generic Steam Encapsulation (GSE), bidirectional satellite communications are possible.
