Abstract: PURPOSE: A packet scheduling method for supporting an IP-QoS(Internet Protocol Quality of Service) in a wireless communication network is provided to perform real-time traffic control with different requirements for delay times in each core router inside an UMTS/GPRS(Universal Mobile Telecommunication System/General Packet Radio System) network, and to meet an UMTS/GPRS QoS standard requesting the provision of QoS differentiated between traffic classes. CONSTITUTION: If a core router receives a traffic packet(601), a traffic class is discriminated according to DSCP(Differentiated Service Code Point)(602). If the packet is included in a conversational class, whether the packet is acceptable in an EF(Expedited Forwarding) queue is checked(603). If not, the packet is discarded(608), and if acceptable, the packet is stored in the EF queue(607). If the packet is included in a streaming class in the step 602, whether the packet is acceptable in the EF queue is checked(604). If not, the packet is discarded(608), and if acceptable, the packet is accepted to the last position of stand-by packets in the EF queue(609). If the packet is included in an interactive class in the step 602, whether the packet is acceptable in an AF(Assured Forwarding) queue is checked(605). If not, the packet is discarded(611), and if acceptable, the packet is accepted to the last position of stand-by packets in the AF queue(610). If the packet is included in a background class in the step 602, whether the packet is acceptable in an BE(Best Effort) queue is checked(605). If not, the packet is discarded(611), and if acceptable, the packet is accepted to the last position of stand-by packets in the BE queue(612). And the stand-by traffic packet is transmitted(613).

Abstract: PURPOSE: A method for controlling a dynamic combined use timer based call connection in an ATM(asynchronous transfer mode) adaptive layer 2 is provided to minimize a consumption of a bandwidth by dynamically controlling a Time_CU value to reduce the time out number and use a remained bandwidth in a traffic for an available bit rate/unspecified bit rat service. CONSTITUTION: When a call is requested(S501), a cell assembly delay time is tested(S503). A Time_CU is increased(S505) and the cell assembly delay time is again tested(S507). The Time_CU is reduced to a previous value(S509) and a call request is received(S511). The Time_CU is compared with a MAX_TCU(S513). When the Time_CU is greater than the MAX_TCU, the call request is received(S511). When the Time_CU is less than the MAX_TCU, steps S505 to S513 are sequentially performed. The Time_CU is reduced(S515) and the cell assembly delay time is again tested(S517). The Time_CU is compared with a MIN_TCU(S519). When the Time_CU is greater than the MIN_TCU, the call request is rejected(S521). When the Time_CU is less than the MIN_TCU, steps S515 to S519 are sequentially performed.

Abstract: PURPOSE: A method for realizing a back operation of a fuzzy neural network is provided to perform a back course of the learning in a fuzzy neural network formed combining a neural network and a fuzzy neuron. CONSTITUTION: A method for realizing a back operation of a fuzzy neural network comprises the steps of: initializing a pure output value of an input layer by the usage of a target fuzzy vector value as an input(102); calculating a presumption inverse of an initial step through activation function from the initializing step(103); forward-feeding an input value transferred to the input layer to calculate an output value(104); examining an ending condition after calculating an error value between the calculated output value and a target output value(106); if the calculated differential value is less than a predetermined error level value, calculating a back propagation value of an error signal(107); calculating a differential value to the pure output value of the input layer by the usage of the error signal(108); after correcting the presumption inverse(109), forward-feeding the input value to return to the step of calculating the output value; and if the calculated differential value is less than the error level value, calculating a new presumption inverse(110).
