3. Network & Server Management Tools

Platform

SVCSVC

■ Networks and Servers are under Surveillance with some tools ■ But they cannot assure

the E2E path is OK and the Services are OK


4. Service management System (WIDAS)

BSC

■ We developed a tool that can simulate user’s input (ex. Request a WAP page) to mobile terminals and make the terminal return the result of the request

■ WIDAS uses exactly the same pathes and modules with common users

4. Service management System (WIDAS) – cont.

■ WIDAS clients get the result and report it to WIDAS server by SMS

■ WIDAS server makes statistics of local networks and CPs

■ WIDAS server provides the Status and Statistics via WEB Server

5. Service management System (CQMS)

■ WIDAS has many merits but some defects as Using precious RF resources Taking relatively long time to measure

■ CQMS compensates WIDAS with monitoring at wired network without wasting RF resources reducing measuring timeAnd, provides the Status and Statistics via WEB Server

6. Evolution of WIDAS & CQMS

■ Monitoring Factors of WIDAS & CQMS now are all about connectivity How long does it take to get information ? How often does it succeed ?

■ As the services increase, More and more factors must be in concern Multimedia : Download time, Quality variation, etc Commerce : Security, High success rate, etc

■ We are now developing additional modules for them
