Title: Remote state management method for mobile communication device
Inventor: JUN CHANG HYEON
IPC: H04B17/00
Filed: 2001-12-24
Abstract: PURPOSE: A method for remotely managing the state of a mobile communication terminal is provided to automatically confirm the abnormality and performance of each mobile communication terminal in an RC(Remote Center). CONSTITUTION: If an RC transmits a message to the UE, for controlling a UE(User Equipment)(S101), the UE receives the message and transmits a response message(S102). The RC transmits a message, for instructing state report, to the UE(S103). The UE transmits state information to the RC, for updating a database of the RC(S104). For testing a traffic state, the RC transmits a loopback test start message to the UE(S105). If a response message about the loopback test start message is received(S106), the RC transmits a load source for the loopback test to the UE(S107). The RC repeatedly receives response messages by the number of set times(S108-S110), and transmits a loopback test completion message to the UE(S111). The UE receives the loopback test completion message, and transmits a response message to the RC, for completing the loopback test operation.

Abstract: PURPOSE: A method for forming an isolation layer of a semiconductor device is provided to be capable of maximizing the rounding effect at top corner of the isolation layer. CONSTITUTION: A pad oxide layer(12), a pad nitride layer and a photoresist pattern for defining an isolation region are sequentially formed on a silicon substrate(11). A trench is formed by selectively etching the pad nitride layer, the pad oxide layer and the substrate using the photoresist pattern as a mask. After removing the photoresist pattern, the top corner portions of the trench are exposed by selectively etching the pad nitride layer. A desired impurity ion is implanted into the top corner portions of the trench. By performing oxidation processing of the resultant structure, an oxide layer(16) is formed on the surface of the trench and the top corner portions are simultaneously rounded. An isolation layer(17) is then formed by filling an insulating layer into the trench. The remaining pad nitride layer is removed.

Title: Method for Generation of Charging Data per Contents in Mobile Communication System
Inventor: KIM JEONG GEUN
IPC: H04L12/14
Filed: 2001-12-31
Abstract: PURPOSE: A method for generating charging data by contents in a mobile communication system is provided to charge a user by contents by generating charging data of each application at a GGSN(Gateway GPRS(General Packet Radio Service) Supporting Node) serving as a gateway between a terminal and an Internet network. CONSTITUTION: A connection procedure is performed between a mobile terminal(201) and a base station controller(202)(211). The mobile terminal(201) requests a PDP(Packet Data Protocol) context from an SGSN(Serving GPRS Support Node)(203)(212). The SGSN(203) transfers a PDP context generation request message to a GGSN(204)(213). The GGSN(204) generates a charging ID and transfers a response to the PDP context generation request to the SGSN(203)(214). The SGSN(203) transfers a response to the PDP context request to the mobile terminal(201)(215). The mobile terminal(201) uses a contents service through a contents server(207)(216). When the contents service is finished, a PDP context non-activation procedure is performed between the mobile terminal(201) and the GGSN(204)(217). The SGSN(203) and the GGSN(204) transfer a CDR(Charging Data Record) generated during the use of the contents service to a charging gateway(205)(218,219). The charging gateway(205) transfers charging data to a charging server(206)(220).
