Planning of features and functionalities for an inter-system protocol analyser

This thesis explores the planning of features and functionalities for an Inter-System Protocol Analyser tool, focusing on 3GPP Release 5 innovations like HSDPA and IMS. Research methods include literature study and interviews with industry experts to define the tool's segments and test the product concept. Key features encompass capacity, performance, decoding, applications, and usability. The conclusions highlight challenges and future research areas.

  1. Planning of features and functionalities for an inter-system protocol analyser • Author: Petri Ylläsjärvi • Supervisor: Professor Sven-Gustav Häggman • Instructor: Markus Ahokangas M.Sc.(Tech.) Petri Ylläsjärvi

  2. Contents • Introduction • Research method – literature study • Research method – interviews • Product concept creation • Product concept testing • Conclusions Petri Ylläsjärvi

  3. Introduction • Motivation for the thesis • Customer requirements for inter-system (2G & 3G) analysers • New possible business potential in 3GPP Release 5 features such as (e.g.): • High Speed Downlink Packet Access (HSDPA) • IP Multimedia Subsystem (IMS) • Research problem • Define features and functionalities for an Inter-System Protocol Analyser (ISPA) tool Petri Ylläsjärvi

  4. Petri Ylläsjärvi

  5. Research method – literature study • GERAN features • GERAN Iu mode • UTRAN features • Iur-g interface • IP transport in UTRAN • HSDPA • Core Network (CN) features • Multiple CN nodes (Iu flex) • IMS • QoS and protocol analysis tools Petri Ylläsjärvi

  6. Research method - interviews • Discussion sessions with 8 interviewees were performed during two months • Customer interviews were left out • Difficult to get answers (time) • Extensive protocol analysis knowledge required • Manufacturer representatives who are working closely with customers were interviewed instead • 38 question concerning different areas were asked totally • Feasible results achieved • It was easy to form an initial product concept Petri Ylläsjärvi

  7. Product concept creation • Four feature and functionality segments were defined • A clear structure for the product concept • Only main features were defined for each segment Petri Ylläsjärvi

  8. Capacity & Performance segment Petri Ylläsjärvi

  9. An open HW platform Petri Ylläsjärvi

  10. Distributed monitoring • Load sharing in monitoring is achieved by using “distributed monitoring” – concept • Master-Slave principle • Excellent solution for remote monitoring etc… Petri Ylläsjärvi

  11. Decoding segment Petri Ylläsjärvi

  12. MultiMedia Decoding - window Petri Ylläsjärvi

  13. Applications segment Petri Ylläsjärvi

  14. Call Trace application Petri Ylläsjärvi

  15. Application example: CAS application Petri Ylläsjärvi

  16. Application example: RIM application Petri Ylläsjärvi

  17. Usability segment Petri Ylläsjärvi

  18. User Interface of the ISPA tool Petri Ylläsjärvi

  19. Product concept testing • Two discussion sessions were performed • To find out missing features • Get feedback for the concept etc… • As one of the results, a new product structure created Petri Ylläsjärvi

  20. Conclusions • Research approach is effective but couple of obstacles exist • Customer interviews require lots of effort and time • Lack of suitable literature • Emerged research topics for the future • IP convergence and Telecom protocol analysers • WLAN and CDMA2000 integrations with the 3GPP systems and their testing with protocol analysers Petri Ylläsjärvi

  21. All research objectives were achieved • The competitive product concept for the protocol analysis tool market was created • Some features are going to be implemented into real products in the near future Petri Ylläsjärvi
