  3. 1. SKT NATE Service • NATE is first wireless Internet service in Korea • NATE is an integrated solution for both wireless and wired Internet • Now, NATE is providing various services including Multimedia and Mobile Commerce Mobile Specific Value Added Information Communication & Message NATE Entertainment & Broadcasting Location based Service Mobile Commerce Communication Message Mobile Office Information • Voice Phone • SMS • Photo Mail • UMS • Text /Image based • Entertainment & • Information • VoD, MoD, AoD • Location Based • Information Service • Mobile Office • Mobile Banking & Trading • Mobile Coupon • Location Based Traffic Information • Navigation

  4. Internet Internet 2. NATE Structure Terminal Network Platform Content Subscriber Access Network Platform Contents Server External CPs WEB Subscriber NATE WEB NATE WAP Mobile Subscriber IS95A/B Multimedia WISS (Highmedia Internet Gateway) SMS Phone MMS (Multimedia Messaging Service) CDMA2000 1X WAP Phone TIG Internal CPs(e-mail, Community, Stock, etc…) MOG (Mobile Office Gateway) EvDO High Media Phone online-SMS VoD Phone IMT- 2000 Billing / Statistics / Subscriber Info.

  5. Network 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 Terminal Network Platform Content Component Tivolli, OMC OpenView,OMC User Internal External SVC SVC SVC SVC SVC SVC Management Tool Platform Platform Platform Network Network Network Network

  6. Network 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 Monitoring Flow Simulates User Input Request CP Returns result get result WIDAS client Monitoring Factors BSC MSC IWF G/W & Platform CP PDSN WIDAS client Traffic Assignment Time, PPP nego. Time, DNS Query Time, and Success rate etc. NATE Home Access Time, and Success rate Content Access Time, Delivery time, and Success rate * WIDAS : Wireless Internet Diagnosis & Analysis System

  7. SMS Network Internet 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 WIDAS Server WIDAS WEB Client WIDAS clients

  8. 4. Service management System (WIDAS) – cont. • WIDAS Screen Shots at WEB Client - Network Geographical Status Status level by Color And Success Rate Local Status Traffic Channel(RF) Assignment time PPP nego. time DNS Query time WAP G/W Access time Time Attempt

  9. 4. Service management System (WIDAS) – cont. • WIDAS Screen Shots at WEB Client - CP Main Menu CP Attempt Success rate Browsing Path Category Content Success Delay Current Status Status Trend of a Content 123-4567 abc@def.co.kr 홍길동 123-4567 Content Administrator Contact Errors in detail Time table Delay Success rate

  10. 4. Service management System (WIDAS) – cont. Trouble CP List Overall error Statistics CP Content Error log w/ level, code, duration Statistics of a CP

  11. Internet 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 Monitoring Flow Simulates Request of terminal G/W & Platform CP CQMS gets result CQMS WEB Client * CQMS : Content Quality Management System

  12. 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 GVM, SKVM VoD, Wavelet WAP (information) WAP (Finance, Banking) WIDAS for PDA WIDAS for VMT
