Hi,

When ENB shut down UE will get UL sync error and it tries RLF in available ENB, While UE doing RLF if ENB comes up then it is ENB implementation to handle it (If old UE context present then it uses same and establish RLF connection otherwise it rejects the RLF). If RLF rejection then UE will start RRC connection request.

While UE doing RLF if ENB comes up ,that time how EPC components behave means what msg enb will send to epc component and if ENB rejects RLF that time what epc component will do (should delete or modify the bearer context).
Sorry i don't know about EPC behavior .
