Default Bearer gets established when a UE attaches with LTE core-network and connects with a PDN network e.g. Internet. Default bearers gives UE an 'always-on' connectivity with that PDN till the time UE is attached. When UE deactivates from that PDN network, its default bearer gets deactivated.

I think deactivation is somehow related to UE ECM-IDLE and ECM-CONNECTED states. In that case, default bearer deactivates when UE moves from ECM-CONNECTED to ECM-IDLE state. As per my understanding, deactivation means "there is no data flow".
