Abstract: PURPOSE: A voice activity detection apparatus and a method thereof in a mobile communication system are provided to distinguish a voice section from a background noise section efficiently while taking over the telephone existing the background noise by using peak measurement(PM) of a residual signal of an LPC(Linear Prediction Coefficient). CONSTITUTION: An LPC analyzer(101) receives and analyzes an input voice signal applied, and then extracts an LPC. An LPC mixer(102) reproduces the voice signal from the LPC. An adder(103) adds up the input voice signal and deducts the signal received from the LPC mixer(102) to produce an LPC residual signal. A PM calculating device(104) performs a PM by using the LPC residual signal. A first flag determining device(105) determines a flag by using the value of PM received from the PM calculating device(104). An analysis and flag determining unit analyzes frame energy and characteristic and distribution of frequency and then determines a flag. A VAD(Voice Activity Detection) device(112) determines a VAD by using a flag received from the analysis and flag determining unit.

Abstract: A method for processing data and a system thereof are provided to check an ICS(Interactive Communication Sequence) for a plurality of users from communication records by using a variable time window as well as an ICSP(Interactive Communication Sequence Pattern) that is an interactive communication sequence frequently generated from among the checked interactive communication sequence. A searcher(121) searches the inverse pairs in the communication record. An ICS extractor(130) includes an ICS extractor without extension of a time window(131) and an ICS extractor with extension of a time window(132), and extracts an interactive communication sequence having a length other than 1. The ICS extractor without extension of a time window checks a new interactive communication sequence in which an interactive communication sequence included in the set S establishes another interactive communication sequence included in the set S as a sub interactive communication sequence, and adds the newly generated ICS to the set S. The ICS extractor with extension of a time window combines the inverse pair that is included in the candidate set S generated by the set generator and the ICS that is included in the set S that is finally determined by the ICS extractor without extension of a time window to generate an ICS having a length other than 1, and adds the generated interactive communication sequence to the set S.
