Abstract: A method for counting coughs is provided. The method includes acquiring a plurality of onset signals from the sound signal, wherein the onset signal has a predetermined time length; acquiring a plurality of spectrograms corresponding to each of the plurality of onset signals; determining whether each of the acquired plurality of spectrograms represents a cough using a cough determination model; and calculating a number of coughs included in the sound signal based on a time point of a cough signal. The cough signal is an onset signal corresponding to one spectrogram determined to represent the cough. When a time interval between a first time point of a first cough signal and a second time point of a second cough is within a reference time interval, the first cough signal and the second cough signal are regarded as one cough signal at the first time point.

Abstract: A method and system for supporting Internet Protocol (IP) mobility of a Mobile Node (MN) in a mobile communication system. In the mobile communication system supporting Mobile IP (MIP) and Session Initiation Protocol (SIP), MIP location registration is performed in a Home Agent (HA) through a first FA (Foreign Agent) of a first foreign network in which the MN is located. When the MN receives a SIP invite message from a Correspondent Node (CN), it sends, to the CN, a SIP response OK message in which a home address of the MN is recorded. The CN sends a packet to the home address of the MN in a state in which a SIP call of the MN is established. The number of signaling messages and a delay time associated with a handover can be reduced, because the CN sends packets only to the home address of the MN regardless of a changed location of the MN.

Abstract: A transmission apparatus and method for compressing headers in a broadband wireless communication system are provided. Upon receiving a packet to which a real-time transport protocol (RTP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header are added, from an upper layer, a header compression protocol layer transmits the received packet without compressing the headers at initial transmission, and from the next transmission, compresses the headers according to a compression scheme provided in Internet technology. A header compression convergence sublayer classifies the packet according to initial-header information received from the header compression protocol layer, stores mapping information for the packet classification, and performs packet classification on a header-compressed packet using the mapping information.
