Stefano 20th December 2002 at 05:17 #34957 Radhakant DasGuest I feel BHCA is convinient on MSC part of GSM network.For Airinterface & BSSAP the affected call processing parameters need to be separately addressed. 28th January 2003 at 07:15 #34958 CindyGuest Hello, I’m new in telecomunication business.Can you explain more what is Busy Hour Call Attempt about ? Why do we need to know about call attempt during busy hour ? 30th January 2003 at 08:29 #34959 StefanoGuest Hi Cindy, BHCA is the total number of attempts that a device (i.e. a switch, BTS, BSC, etc.) receives in the busy hour. We commonly measure network traffic load during the busiest hour because this period represent the maximum traffic load that your network must support.
