I checked & found when MSC send authen req to some MS many times, MS don’t return authen response. Any idea about that problem. Thank you 22nd July 2012 at 06:19 #68453 pixGuest hi jimmi, it is possible that the radio connection has dropped. Try to correlate your KPI Authentication % to the SDCCH Drop % in those cells. If the KPIs are correlated (i’m not saying equal !!) then your problem is probably linked to a problem on the radio side. The authentication is the first stage of the SDCCH phase, as far as i remember.
