摘要： A first terminal generates a first scheduling request signal including information about first data resources for data transmission when the first terminal tries to reserve the first data resources. The first terminal generates a first scheduling request indication signal providing notification that the first scheduling request signal is to be transmitted. The first terminal transmits the first scheduling request indication signal through a first request subslot included in a first scheduling request resource before transmitting the first scheduling request signal. The first terminal transmits the first scheduling request signal through a second request subslot included in the first scheduling request resource.

摘要： A fragmentation repetition detection apparatus (410) for detecting an IP fragmentation repetition which may occur in a multicast or unicast environment is provided. The fragmentation repetition detection apparatus (410) includes a packet capturing unit (411) which captures a received packet, a fragmentation repetition detector which detects whether or not the captured packet is a packet which is repetitively fragmented, and a path maximum transmission unit (PMTU) transmitter (414) which transmits PMTU information acquired by the fragmentation repetition detector (412) to a server which transmits the packet when the captured packet is a packet which is repetitively fragmented. Since a packet is transmitted by readjusting a PMTU, a fragmentation of an IP packet can be prevented.

摘要： Provided is a method for providing Internet protocol (IP) handoff of a mobile node (MN) under a multiple mobile agent platform (MAP) environment. In the method, a registration request message for an IP handoff is received from an MN in a network including a plurality of MAPs, and information about the MN is shared with an MAP managing an area in which the MN is located before through a signal packet path. The signal packet path is established separately from a data packet path for transmitting signal packets associated with IP handoff. An IP handoff for the MN is provided based on the shared information. Therefore, a rapid IP handoff is possible since the two MAPs share information about the MN with each other.

摘要： Disclosed is an optical receiver and an error correction method performed by the optical receiver, receiving, using a receiving antenna or a photodetector, a training signal in which an error occurs due to noise and distortion while being output from an optical transmitter and transmitted through a communication channel and identifying a hyperplane for classifying a probability that the received training signal is a training signal corresponding to a training signal output from the optical signal using a support vector machine (SVM) and learning a parameter of the identified hyperplane such that a classification error probability is minimized when the probability is extracted using the identified hyperplane, wherein the parameter of the identified hyperplane is used to correct an error occurring while a transmission signal output from the optical signal is received using the receiving antenna or the photodetector.
