Title: A delay locked loop circuit
Inventor: PARK BYEONG IL
IPC: G11C8/00
Filed: 2001-12-21
Abstract: PURPOSE: A DLL(Delay Locked Loop) circuit is provided to improve a time for setting a new lock-in state by maintaining an enable state of a low pass filter. CONSTITUTION: A DLL circuit includes a delay chain portion(22), a shift register portion(23), a phase comparison portion(21), a shift control portion(24), and a low pass filter portion(25). The delay chain portion delays a reference clock and generates an output clock. The shift register portion controls a clock delay time of the delay chain portion according to a stored register value. The phase comparison portion generates the first shift signal and a lock-in release signal by comparing the reference clock to a phase of a feedback clock of the output clock. The shift control portion determines a state of lock-in by using the shift signal and the lock-in release signal. The shift control portion generates a delay locked signal if the state is lock-in state, and transfers the first shift signal to the shift register portion if not. The low pass filter portion generates the second shift signal by using the first shift signal when receiving the delay locked signal.

Title: Method of displaying the voice calling sign during data communication for a user terminal of telephone network and apparatus thereof
Inventor: KIM DAE UNG
IPC: H04M3/02
Filed: 2001-12-27
Abstract: PURPOSE: A method and a device for displaying a voice call signal during data communication of a user terminal in a telephone network are provided to display the voice call of another user on the terminal of the wired and wireless telephone network subscriber, even while the user terminal performs data communication through an Internet connection device. CONSTITUTION: A subscriber-B terminal requests a call for data communication to an exchange(301). The exchange transmits an originating number of the subscriber-B terminal and call request information to an Internet connection device(302). The Internet connection device stores the originating number of the subscriber-B(303), and permits an Internet connection of the subscriber-B terminal to provide a data communication service(304). If a subscriber-A terminal requests a call for voice communication with the subscriber-B to the exchange(305), the exchange checks whether the subscriber-B terminal is in a busy state(306), if so, to transmit a call request for voice communication of the subscriber-A terminal to the Internet connection device(307). The Internet connection device searches an originating number of the subscriber-B terminal(308) to check whether the subscriber-B terminal is performing data communication(309). If so, the Internet connection device transmits a request to display voice call information from the subscriber-A terminal to the subscriber-B terminal through the exchange(310). If the subscriber-B terminal is not performing data communication, the Internet connection device decides that the subscriber-B terminal is performing voice communication and transmits busy state information of the subscriber-B terminal and a disconnection message to the subscriber-A terminal through the exchange(311,312). If the subscriber-B terminal is not in a busy state in the step 306, the exchange transmits a voice call to the subscriber-B terminal(313).

Filed: 2001-12-28
Abstract: PURPOSE: A method for changing up-browser setup is provided to implement up-browser setup in an up-browser mode as well as in an idle state, so that a user conveniently changes the up-browser setup. CONSTITUTION: An up-browser setup device comprises a key input unit, a controller and a displayer. The key input unit transmits an up-browser setup selection signal and an up-browser setup change signal to the controller, and the controller changes an up-browser mode to a sub up-browser setup mode and changes up-browser setup. If the up-browser setup selection signal is inputted, the displayer displays a sub up-browser mode for an operator. When the up-browser setup is changed, the controller maintains the current up-browser mode, and at the same time operates the sub up-browser mode(S100). The controller receives the up-browser setup change signal through the sub up-browser from a user(S200). And the controller changes the current up-browser setup according to the up-browser setup change signal inputted from the user, and loads an up-browser on a screen(S300).
