| Escalation of calculative data from raw data |
- For Delimitation process use tab, space, coma, semicolon as a separator, our intention is to separate numerical value from the text.
- Then arrange the data into appropriate format, like MO call setup time and user setup time, separate the time unit (ms). In a single row please keep only numerical values.
 |
| Organized data for call setup time calculation |
- Then go to sub column "Time" calculate the average MO call setup time and also "user setup time". User setup time is generally a time which requires the user to peak up the incoming call. If the call is peaked up by manually no need to calculate "user setup time". In this case calculate only "MO call setup time" and average value of "MO call setup time is the actual call setup time. For this type of case formula will be:
- If incoming call is peaked by the automatically predefined system then calculate the both " MO call setup time" and "user call setup time". For this type of case formula will be:
Tools for call setup calculation:
TEMS Investigation (data collection software).
Mapinfo professional (minimum version 8.5 scp)
Microsoft excel (calculation and data arrangement)
Caution:Never try to manipulate any data, because frame number is included with Exported file and in Raw data, so customer can trace you at any time.
Note: This procedure is only applicable for TEMS Investigation data collection software.
