Claim of US Patent No. 9,591,502

1. A method for feeding back minimization drive test (MDT) logs, the method comprising:
determining whether a terminal equipment connects to a target cell by switching from an idle state to a connection state,
or reestablishes to a target cell in a connection state, or alters from a current attribution cell to a target cell during
a connection state, and upon positive determination thereof, said terminal equipment verifying whether feeding back MDT logs
across arbitrary attribution zones is permitted;

if said terminal equipment verifies that feeding back the MDT log across arbitrary attribution zones is not permitted, said
terminal equipment judging whether an attribution zone corresponding to evolved Node B(s) (eNB(s)) of said target cell is
a predefined valid attribution zone; and

if a judgment result is “Yes”, said terminal equipment sending log available message to eNB(s) of said target cell.
