MME may initiate paging procedure for an UE , when network wants to enable trace for an UE. It is my just my thought since nothing is mentioned in standard specification.

* ETWS notifications
* CMAS notifications

In a PS (only) network, why do we see MME paging to UE after some time? Does it mean UE goes idle on Uu interface (possibly short inactivity timer on eNB) while it had requested for some data earlier but before data reaches at S-GW, UE has already moved Idle mode? Please explain
