backtotop.gifTraining Course Description

Course Description

  • This training course is targeted at engineers and technicians who are involved in the operation, optimization and troubleshooting of UTRA-networks.
  • This fascinating blend of practical experience and theoretical knowledge is a must for everybody who shall tune a UTRA-network.
  • The training course starts with a detailed description of important UTRA-parameters throughout the various protocols and continues with the consideration of how specific parameter settings and setting combinations influence the system operation.
  • In another part, the training course answers your questions with respect to network dimensioning and load aspects in both the terrestrial and the wireless parts of UTRA.
  • Finally, the training course provides guidance on how and where to setup performance measurements for circuit-switched and packet-switched performance measurements within UTRA.
  • The training course concludes with the detailed analysis of typical errors and failures in UTRA networks, discriminating mobile station issues from network problems.
As in all INACON training courses we integrated several interactive exercises for a perfect learning experience.

Some of your questions that will be answered

  • What does network performance in UMTS stand for and how does it compare to GSM- or GPRS-network performance?
  • How can I determine our actual network performance?
  • What is meaning of the parameter “Received-total-wide-band-power” which is conveyed from the NodeB to the RNC during radio link setup?
  • How can I measure and compare the quality (Bit Error Rate / Frame Erasure Rate) per cell, per NodeB or per RNS on the Iub-Interface for both uplink and downlink?
  • How can I distinguish application and user equipment failures which are outside of our scope from real network problems?
  • What is the meaning of the various timers and counters which are broadcast in the System Information Blocks
  • Which system parameters can I tune to optimize the UE’s idle mode behavior? (e.g. S-intrasearch, t-Reselection-S, Qhyst, Qoffset, ...)?
  • How can I nail down performance bottlenecks in the different parts of our network?
  • How can I minimize the interference through the use of diversity transmission methods?
  • How can I optimize the network access procedure for both, minimum delay times and minimum interference.
  • What is the optimum configuration of the different RLC counter and timer values (e.g. Max-DAT, timerPoll, transmissionWindowSize, …) to provide the best possible service for transparent, unacknowledged and acknowledged operation modes.
  • What are the best measurement tools for the Uu-interface and within UTRA?

backtotop.gifWho should attend this class?

  • Network operator staff who are involved in the optimization of UTRA and who need to continuously improve the network performance.
  • System vendors who are involved in second and third level troubleshooting activities


  • Previous practical exposure to network optimization and trouble shooting in GSM, GPRS or UMTS (second level) is required.
  • Very good understanding of the related UTRA- and NAS-protocols is necessary.
  • We strongly recommend to join our training training courses “UMTS – Design Details & System Engineering” and
    UMTS - Signaling & Protocol Analysis” before visiting this course.
  • Previous practical experience with network protocol testers and test UE’s (e.g. TEMS) is desirable.
