PURPOSE: A system and a method for a customized music service according to the user's preference are provided to suggest music preferred to the user and the music having high similarity on the web by constructing a database of the music files provided from a music service system through classification and storing the characteristic information of each genre. CONSTITUTION: A client terminal(100) accesses the system through the Internet(106), sends a music file play request to the system, and plays the music file provided by responding to the request. A music service server(108) stores diverse music files and the characteristic information value of each music in the database(110), searches the characteristic information value of the music preferred by each user and the music files having the high similarity from the database(110), and offers it as the preferable music file of the corresponding user. The music service server(108) includes an audio database module, an audio signal extraction module, and an audio quantization module.

Abstract:
An AODV(Ad hoc On-Demand Vector routing) route recovery method using a candidate node and an apparatus thereof are provided to minimize network traffic loads and a network bandwidth burden by reducing the volume of RREQ(Route Request) messages in case route loss occurs in the middle of communication using an AODV techniques in an Ad-hoc environment. An AODV route recovery apparatus consists of an RREQ message transmitting part(510), an RREP(Route Response) message receiving part(520), a data transmitting part(530), and an RERR(Route Error) message transmitting part(540). The RREQ message transmitting part transmits an RREQ message to find out a candidate node, 2 hops from a middle node, on the route to a destination node. The RREP message receiving part receives an RREP message from the candidate node, including the address of the candidate node. The data transmitting part transmits data to the destination node through the candidate node, and adds the address of the candidate node to the routing table. The RERR message transmitting part(540), if the RREP message is not delivered from the candidate node, transmits an RERR message to a source node and requests the source node to search the route independently.

Abstract:
PURPOSE: An IP(Internet Protocol) paging structure having a function to distribute buffering loads and an implementation method therefor are provided to distribute buffering loads evenly to routers in a paging area during a paging process, thereby preventing buffering from being concentrated on a PA(Paging Agent) and providing efficient IP paging. CONSTITUTION: An HA(Home Agent)(101) intercepts packets, if the packets reach a call network of a mobile host(106) in an idle state, and delivers the packets to a COA(Care Of Address) of the mobile host(106) through tunneling. A PA(104) buffers the packets delivered from the HA(101) until a location of the mobile host(106) is detected, while transmitting a paging signal for detecting the current location of the mobile host(106) and distributively forwarding the packets to a paging area evenly. And a plurality of routers(105) arranged in the paging area transmit the paging signal delivered from the PA(104) and buffering data to the mobile host(106) through a paging channel in a wireless section.

PURPOSE: A method of analyzing an ultrashort pulse spectrum is provided to analyze spectrums shown in time domain functions and frequency domains for the ultrashort pulse having various shapes and widths and power spectral density which is transmitted with digital data. CONSTITUTION: An ultrashort pulse generator(110) generates an ultrashort pulse sample, a pulse profile measuring device(120) outputs a profile(130) of the ultrashort pulse. Accordingly, the spectrum and transmission characteristics are uniformly analyzed by applying high-order pulses to the ultrashort pulse according to a width of full width half maximum. That is, the high-order pulses are fixed by selecting the TAB coefficient of model, thereby easily analyzing various spectrums of the ultrashort pulse and transmission characteristics by adjusting the TAB coefficient.
