IPC: H04W16/00
Filed: 2002-11-22
Abstract: PURPOSE: A neighbor list statistics processing method is provided to allow an operator to optimize wireless environment by collecting and analyzing neighbor PN(Pseudo Noise) statistics data. CONSTITUTION: A terminal transmits a PSMM(Pilot Strength Measurement Message) to a BSC(Base Station Controller)(S310). The BSC receives the PSMM(S320) and collects neighbor PN statistics data by source base stations/sectors with respect to each target base station/sector(S330). A call control processor periodically reports the neighbor PN statistics data to a base station manager(S340). The base station manager is reported on the neighbor PN statistics data(S350) and stores it(S360). The base station manager periodically reports the neighbor PN statistics data to a network management system(S370). The network management system is reported on the neighbor PN statistics data(S380), stores it, and provides it to a network management operator(S390).

Title: A Method For User authentication in Public Wireless Lan Service Network
Inventor: KIM JEONG HWAN
IPC: H04L12/28
Filed: 2002-12-02
Abstract: PURPOSE: A user authentication method in a public wireless land service network is provided to protect a user by informing the user that someone else accesses the Internet with the same ID from a different place at the same time zone. CONSTITUTION: An authentication server receives a user ID of a subscriber(401). The authentication server searches a user authentication table to check whether there exists the user ID(402,403). If there is the user ID, the authentication server searches and stores an authentication record corresponding to the user ID(404). The authentication server checks whether to perform authentication with a MAC address stored in the record(407). If an item of 'MAC checking' is set as 'yes', the authentication server compares a user MAC address of an authentication protocol and the MAC address of the authentication record(408). If both MAC address are identical or the item of 'MAC checking' is set as 'no', the authentication server sends an EAP(Extensible Authentication Protocol)-Challenge message to a wireless LAN AP(410), and then, receives an EAP-Challenge response message(411). The authentication server checks whether passwords are identical through an MD5 hash of the Challenge response(412). If passwords are identical, the authentication server checks an item of 'log-in state'(415) and compares set values(416). If the item of 'log-in state' is set as 'no', the authentication server generates an EAP success message(419), transmits it to the wireless LAN AP(420).

A shaft(42) with a first mandrel(40) and a shaft with a second mandrel(50) are inserted to both ends of a tube(32) and connected to each other. The tube is turned and moved from the first mandrel to the second mandrel, and the inner wall of the tube is contacted to the first mandrel. The shaft with the first mandrel is fixed, and the shaft with the second mandrel is rotated with the tube.

Abstract: PURPOSE: A system for measuring continuously coupling loss of leakage coaxial cable is provided to measure a coupling loss of a coaxial cable if only a measurer sets a measuring environment. CONSTITUTION: A system for measuring continuously a coupling loss of a leakage coaxial cable comprises a half-wave antenna movable along the leakage coaxial cable for receiving leakage electric field emitted from the leakage coaxial cable; a spectrum analyzer(80) for calculating a strength of the leakage electric field by receiving the leakage electric field; a computer for outputting a plurality of coupling loss data and having a coupling loss measurement program; and an interface unit(100) for interfacing an input of the measurement data of the leakage electric field from the spectrum analyzer to the computer.
