3. Network & Server Management Tools

  • 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)

  • 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 time

      And, 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
