The most reliable way is to check your QoS indicators. SDCCH drop is a very common indicator among all vendors.
or if you’re just doing a drive test, you’ll have to check the layer 3 messages. If there’s a stop in the sending and receiving of the SDCCH messages (authentication, ciphering, etc…), then you can assume it is a SDCCH drop.
