Narrative:
I heard ATC make a call to nxxx to descend to FL390. Our tail number is nxxy. Thinking that the call may have been for us; we started to call ATC and make an inquiry when we received a TA from our TCAS system. It seemed that a sudden; frantic call came from ATC to another aircraft for them to climb immediately to FL410. We then received; simultaneously; a clearance to descend to FL390 and an RA. We followed the RA and descended at the indicated rate until advised by our TCAS that we were 'clear of conflict.' we leveled at FL390; continued to our destination without further incident.
