  2. 2. OPTIMIZATIONOptimization is intended to provide the best network quality using available resources as efficiently as possible
  3. 3. INTRODUCTION TO TEMS• Drive testing is the most common and maybe the best way to analyze Network performance.• Drive testing is basically recording measurement data which can also be analyzed afterwards.• It gives idea about what’s happening with a subscriber point of view.
  4. 4. CONTENTS The information provided by TEMS is displayed in status windows. This information includes• cell identity, base station identity code, BCCH carrier ARFCN, mobile country code, mobile network code and the location area code of the serving cell.• There is also information about RxLev, BSIC and ARFCN for up to six neighboring cells;
  5. 5. CONTENTS• channel number(s), timeslot number, channel type hopping channel indication, mobile allocation index offset and hopping sequence• RxLev, RxQual, FER, DTX down link, TEMS Speech Quality Index (SQI), timing advance (TA), TX Power, radio link timeout counter and C/A• parameters for the radio environment.• The signal strength, RxQual, C/A, TA, TX Power, TEMS SQI and FER of the serving cell and signal strength for two of the neighboring cells can also be displayed graphically in a window.
  6. 6. USING SOFTWARE• Tailored settings• Default tabs• Basic windows• Maps—gst• Recording properties• Exporting log files• Report generation
  7. 7. ANALYSIS OF LOG FILESAnalysis is the most important part. Lets look at some of the cases.• Dropped call - Nbr not defined• Dropped call – RL Timer expires• HO Failure
  8. 8. Lack of Dominant ServerSignals of more than one cell can bereaching a spot with low level causing pingpong handovers. This might happenbecause the MS is located on the cellborders and there is no any best server tokeep the call.
  9. 9. Drop Call due to Bad Coverage• Call is dropped because of poor coverage.• The signal level goes down below the minimum signal level that system could carry on
  10. 10. Bad Quality due to Signal Strength• FER is Bad• FER is good implies no obviuos interference in the area.
