Cisco 1941 3G snmp traps

Hey everyone, I'm wandering if anyone can help me with snmp traps for 3G cellular interface on Cisco 1941 routers.

I have a router with high speed connection on GigE0/0. When the high speed connection drops, router brings up the cellular interface and connects to the internet over that. I have configured the router to send SNMP traps to my NMS when cellular connection-status changes. This is what I have configured. This configuration is allowing my NMS to receive the traps however it gets the exact same trap for All-gsm states hence can't differentiate between a connection-status ACTIVE to a connection-status INACTIVE
