Abstract: A network coding system of a multicast member node is provided to increase the data transmission rate by synthesizing and outputting the data transmitted after being scattered through multicast paths. An overlapping existence decider(110) checks whether or not plural multicast paths are placed at an overlapped position. If so, a network coding unit(120) codes the data transmitted after being scattered through each multicast path, and outputs the network coded data. A tree information receiver(130) receives multicast tree information from each multicast path.

Abstract: A method for determining a hysteresis margin, a handover triggering method, and a mobile station performing the same are provided to reduce unnecessary handover by increasing the probability that the handover is performed to the cells of which qualities are expected to be improved most rapidly among adjacent cells. The intensity of a signal received from a serving cell and an adjacent cell during collection interval is obtained(S103). By using the intensity of the signal, the inclination of linearized signal corresponding to the serving cell and the adjacent cell is deduced(S105). By using the inclination, the hysteresis range corresponding to the adjacent cell is determined(S106).

Abstract: A device for determining the number of paging groups in a mobile communication system, a method therefor, and a paging method using the method are provided to determine the paging groups in order to reduce an error during a paging indication procedure as decreasing battery consumption of a terminal in the mobile communication system where paging indication is performed through the paging groups. When a base station receives an information delivery indication message including number information of an idle- state terminal from a paging server, the number information of the terminal is stored. The base station calculates the number of paging indicators by using the stored idle-state terminal number information, active-state terminal number information, paging group reflecting coefficients, maximum number information of the idle-state terminal, and maximum number information of an active-state terminal. The calculated paging indicator number information is included in a system information message, and the message is transmitted to the terminal.

Abstract: A vertical handoff method is provided to prevent degradation of performance due to an increase in a delay time of vertical handoff, degradation of data throughput, degradation of terminal battery efficiency, and an increase in probability of a failure of vertical handoff. A serving network of a terminal is determined(S110). When the serving network is the first network and an RSSI(Received Signal Strength Indication) received from the second network is greater than the first threshold value, it is determined whether to perform the first vertical handoff by using a result obtained by estimating a transition pattern of the RSSI(S103,S105,S107,S109). When the serving network is the second network and the RSSI received from the second network is smaller than the second threshold value, it is determined whether to perform the second vertical handoff by using a result obtained by estimating a transition pattern of the RSSI(S111,S113,S115,S117,S119).
