thanks.
that is a valuble data.
i want to make it more interesting in calculating no. of erlangs per sub per hour.
TCH load per subscriber
= [ # of call attempts per sub per hour*%MOC + # of call attempts per sub per call*%MTC*(1-%no response)*(1-% no answer)*%MTC success] * mean call duration /
3600
example
1. number of call attempts (MOC+MTC) per subscriber per hour 1.1
2. percentage of MOC 60%
3. percentage of MTC 40.0%
4. no answer from a mobile subscriber 13.5%
5. no paging response 32.5%
6. successful MTC 54.0%
7. mean call duration (MOC/MTC) 115 sec
if now calculate erlang per subscriber
=[ 1.1 * 60% + 1.1 * 40% * (1-32.5%) * (1-13.5%) * 54%] * 115/3600
= 0.026 Erlang
hope this is useful
thnks n regards
