摘要： A system for electronic monitoring includes a control server and a plurality of monitoring servers. The control server transmits electronic monitoring instructions including identification information on terminals to a plurality of monitoring servers, respectively, based on information of objects to be monitored stored in a database, receives an object confirmation request message including information on suspect object packets from a first monitoring server among the plurality of monitoring servers, and determines whether the monitoring object terminals correspond to suspect object terminals that transmit or receive the suspect object packets according to the object confirmation request message based on the information on the monitoring objects. When the suspect object terminals are the monitoring object terminals, the control server updates the database based on the information on the suspect object packets.

摘要： There is disclosed an echo cancelling apparatus in a digital mobile communication system and method thereof, which is incorporated in a single chip together with a speech coder, and can improve convergence rate by using an excited signal as an input to n adaptive filter and also obtain a stabilized convergence characteristic while using a NLMS algorithm. The echo canceller according to the present invention uses the excited signal obtained at the speech coder as an input signal to an adaptive filter thereby to lower the Eigenvalues distribution rate of the speech signal, thus providing an improved performance compared to the conventional echo canceller.

摘要： In a lawful interception system including an interception unit, an application service providing unit, and an Internet access service providing unit, the application service providing unit may receive, from the interception unit, an interception request including interception target information of an interception target. Next, the application service providing unit may transfer a user code corresponding to the received interception target information to the interception unit, and may insert user related information into a packet to be provided to the interception target corresponding to the user code, enabling the packet to be lawfully intercepted. The interception unit may request the Internet access service providing unit for an interception of the packet with respect to the interception target by including the user code.
