Title: Data caching method of relational database
Inventor: CHOI CHEOL HO
IPC: G06F17/30
Filed: 2001-12-27
Abstract: PURPOSE: A method for caching data on a relational database is provided to decrease the load of a server by storing a code table in the database of a client and converting the decoded data into a code as referring to the code table stored in the database of the client. CONSTITUTION: The client confirms the existence of the code table storing in the database by inputting a keyword to a code name field(302). If the code name corresponding to the keyword exists, the code table is transmitted to the client(306). If not, the client requests the data of the code table corresponding to the keyword by connecting to the server, the server transmits the corresponding code table to the client, and the transmitted code table is stored in the database(308). The client decodes and outputs the code table(310,312). The decoded data is converted into the code(314).

Abstract: PURPOSE: An automatic switching device for an ATM(Asynchronous Transfer Mode) switch is provided to sense a packet error and select a link automatic switching through probability, when fault is generated in a dual port of a switch board of the ATM switch. CONSTITUTION: A CRC(Cyclic Redundancy Check)-32 logic generating unit(10) generates a CRC-32 logic signal, and transmits the generated CRC-32 logic signal to an object card through a link. CRC-32 check units(20,30) receive CRC-32 signals from the object card, and transmit counter signals and CRC-32 error state information to a dual logic(40). The dual logic(40) receives the counter signals and CRC-32 error state information from the CRC-32 check units(20,30), monitors a packet error, and generates a link switching execution command. A selecting unit(50) receives the link switching execution command, selects a link to be automatically switched, and transmits a signal to a switch device.

Title: Method for managing network in mobile communication system
Inventor: KIM TAE HYEON
IPC: H04B7/26
Filed: 2002-01-23
Abstract: PURPOSE: A method for managing a network of a base station in a mobile communication system is provided to transmit a command of solely receiving a signal having a reassemble PN offset to a mobile communication terminal, if strength of a pilot signal is smaller than specific size, thereby controlling the number of sectors. CONSTITUTION: A base station creates an optional reassemble PN offset(101), and transmits a reassemble pilot signal to a mobile communication terminal(103). The terminal transmits a reassemble pilot signal strength response message to the base station(105). The base station transmits a traffic signal having an inherent PN offset with a traffic signal having the reassemble PN offset to the terminal(107). The terminal simultaneously receives the traffic signals(109). The base station increases strength of a reassemble pilot signal, and reduces strength of an inherent pilot signal, then transmits the signals to the base station(111), and transmits each pilot signal strength response message to the base station(113). The base station decides whether the strength of the inherent pilot signal is smaller than specific size(115). If so, the base station commands the terminal to solely receive signals only having the reassemble PN offset(117). The terminal stops receiving signals having the inherent PN offset, and receives the signals having the reassemble PN offset only(119).
