It is up to the network to decide what ID type it wants to use to page a mobile, and this is dependent on a number of factors. Almost always it uses the TMSI, sometimes IMSI, and _very_ rarely an IMEI.
In gsm 04.08 9.1.22.3 it says "The Mobile Identity 1 and 2 IEs shall not refer to IMEI.". So a standard compliant network should never do that.
Have you actually seen that on any live network?
So in short, unless youre lucky enough to have the network page you with your IMSI, it is unlikely you will see it.
Sometimes when some network components like the auth server/vlr are overloaded with entrys or requests, then there are many imsis on the air. And often at not-so-busy times, too. I've observed that regulary but have not heard any fully explainatory conclusion to that yet.
