Dear All,
I have some question to make me confuse ? What difference between Call attempt and Seizure Call ??
And I found some statistic in ERICSSON switch..Seizure Call more than Call Attempt… How come ?? Why it happen like that ? T_T
As Ericsson explains CCALLS can be stepped several times during a call setup, due to for instance congestion or several received Random Accesses (RAs) from a mobile. This could result in very high values for these counters in problem cells and should be considered with care in those cases. The formula below has compensated for the attempts at congestion.
The number of SDCCH establishments in relation to the number of seizure attempts (when no SDCCH congestion) can be calculated as follows
S_est=CMESTAB/(Ccalls-(Ccongs+Ccongssub))
Hope this will clarify the issue.please send to me
