pdf_gross.gifBootcamp - Mastering the UTRAN and Uu Interface

backtotop.gifAt the end of the Bootcamp you will:

  • An increase in your job efficiency
  • The ability to trouble shoot UTRAN drops
  • Expertise in your measurement equipment
  • The ability to analyze protocol traces
  • Knowledge on the root cause of abnormal releases
  • Understanding of interworking problems on Iub and Iu/Iur
  • The ability to identify Pilot Pollution situations
  • The ability to resolve badly covered or interfered areas
  • Expert knowledge about Missing Neighbor severity

backtotop.gifKey Topics

  • Call Trace on Iub by using CRNC- & NodeB Comm. Context Ids + Binding Id & SUGR + VPI/VCI&CID
  • Drop Call Filtering upon Iu Release Request
  • SCCP Signaling allowing call tracing based on Local Reference Numbers
  • RANAP protocol with SAI and Initial UE Message
  • RNSAP on Iur for Macro Diversity
  • Soft handover events 1a, 1b, 1c
  • Hard handover event 2d -> 3a
  • RRC and Iub & Iu User Plane Call Tracing
  • Idle Mode Behavior of UE

backtotop.gifWho should attend:

  • UTRAN Field Technicians and Engineers
