hello All

Number of MOC random access attempts = 926

Number of successful MOC random accesses= 883

Number of CM service requests of MOC= 711.

926-883=43 why failure 43

883-711=172

could you expialn these number??

from the defination we see that Number of successful MOC random accesses=Number of CM service requests of MOC but in the result it is not

Number of CM service requests of MOC= 711
This counter counts the number of accesses due to CM SERVICE REQ of MOC. After BSC receives the EST_IND message, if the access cause in the layer-3 information in this message is “CM SERVICE REQ”, this counter increments.
This counter is used to find out the frequency of the access due to CM SERVICE REQ of MOC.

Number of MOC random access attempts = 926

It represents number of random access requests due to MOC. If
TA does not exceed cell range, BSC treats random access
request as valid MOC and increments the counter.

Number of successful MOC random accesses= 883
It represents the number of successful random accesses when
BTS assigns a channel to MS due to MOC. After successful
access, MS sends EST_IND to BSC through BTS. Counter
increments when BSC receives EST_IND.
