Plz is there is any one of you suffer from abnormal increase on the SDCCH Drops (Huge increase) specially during the early hours where there is no any traffic, we have this increase and we make extensive analysis.25th January 2010 at 06:54 #60846MFGuest
PLS SPECIFY WHICH VENDOR U R USING? OVER ALL THE PROBLEM CAN BE OVERSHOOT, MISSING NEIGHBORS, INTERFERENCE, MISSING HO ON SIGNALLING CHANNELS, TX LINK STABILITY, HARDWARE FAULTS ON TRX, BTS,BSC OR EVEN MSC WISE.
IN CASE OF CLARIFYING THE VENDOR, WE WILL BE ABLE TO GIVE U MORE EFFICIENT IDEAS AND SOLUTIONS1st February 2010 at 13:31 #60847ZbigniewGuest
we see the same problem in Nokia BSS. The SDCCH Drop Rate rises if there are many location updates in the cell or when the traffic is low.
