I’m a bit confused about the “NO HANDOVER COMMAND”. You mean the BSC doesn’t send a HO CMD to the MS, right ?
Because the msg “NO HO CMD” doesn’t exist. Sorry if i sound stupid, it’s just confusing 🙂
So BSC doesn’t send the msg, even though the radio conditions should lead to a HO.
On the opposite, if the MS wasn’t being called before, while being already busy, under the same radio conditions, the BSC would send a HO CMD.
If that’s what you’re observing, then yes, this should be investigated in a lab… what are the vendors of the MSC and BSC ?
