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： There are provided an apparatus and method for recovering a clock signal from a burst mode signal. A first delay delays an input data signal for half of a time period of the input data signal, and produces a first delay signal. An XOR gate adds the input data signal and the first delay signal provided from the first delay, and provides an inverted signal of the added signal. An OR gate adds an output signal of the XOR gate and a second delay signal, and provides the added signal as a recovered clock signal. A second delay delays the added signal provided from the OR gate for an integer multiple of a time period of the input data signal, and produces the second delay signal that is provided to the OR gate. The frequency of the recovered clock signal is not limited by any delay in the gate elements due to a phase transition of the input data signal occurring when every other packet is provided.
