Abstract:
PURPOSE: A deep packet checking device and a method thereof are provided to trace a packet of a specified user continuously when handover according to movement of a user is generated. CONSTITUTION: A receiver(61) receives the first deep packet checking result about packets of a terminal from a first sub-net before handover when the handover is generated. The receiver receives the second deep packet checking result about the packet of the terminal from the second sub-net after the handover. A coordinator(62) re-arranges the first deep packet checking result and the second deep packet checking result when the handover is generated. The coordinator generates the third deep packet checking result.
Abstract:
PURPOSE: A PSTN(Public Switched Telephone Network) interface apparatus for narrow band service in an optical subscriber transmitter is provided to miniaturize an ONU(Optical Network Unit) in the side of the narrow band service, thereby capable of using a limited bandwidth effectively. CONSTITUTION: A DS1E line interface unit is dependent on an OLT(Optical Line Termination), is interfaced with a PSTN exchange through a DS1E interface structure and with an ATM switch through a B-ISDN interface device, and converts the DS1E signal transmitted from the PSTN exchange digitally and then changes into E1 frame and vice versa. A TSI unit allocates a time slot constructing E1 signal transmitted from the DS1E interface unit according to a command of a V5 processor to a provisioned subscriber's channel and vice versa. An ATM Inter-Working unit performs a function for reconstructing E1 data transmitted from the TSI unit as an ATM signal in order to transmit it to an upper ATM layer and vice versa. An S/UNI unit performs a function for transmitting the ATM signal to the B-ISDN interface unit and vice versa. The V5 processor performs a call processing function, a control function of time slot position reconstruction, an N-ISDN D-channel information processing function and a signaling processing function. A V5 processor interface unit performs a V5 message transmission function, an N-ISDN D-channel information transmission function and CAS(Channel Associated Signaling) function.
