Method for processing handover failure, and user equipment

摘要

The disclosure provides a method for processing handover failure, and user equipment (UE). The method comprises: UE failing in handing over from a first cell to a second cell; the UE failing in performing radio resource control (RRC) re-establishment in the first cell, the second cell or a third cell, and succeeding in performing RRC establishment in a fourth cell; a network element to which the user equipment in a connected state is connected sending a physical identifier of the second cell to a network element to which the first cell belongs. The disclosure can ensure that the network element to which the first cell belongs carries out accurate judgment of handover situations according to the physical identifier, which can ensure the optimization of handover parameters.

1. A method for processing handover failure, comprising:
sending, by a network element to which User Equipment (UE) in a connected state is connected, a physical identifier of a second cell to a network element to which a first cell belongs; wherein before sending the physical identifier of the second cell to the network element to which the first cell belongs, the method comprises: the UE failing in handing over from the first cell to the second cell; and the UE failing in performing Radio Resource Control (RRC) re-establishment in the first cell, the second cell or a third cell, and succeeding in performing RRC establishment in a fourth cell; wherein sending, by the network element to which the UE in the connected state is connected, the physical identifier of the second cell to the network element to which the first cell belongs comprises: handing over, by the UE, from the fourth cell to a fifth cell; reporting, by the UE, the physical identifier of the second cell to a network element to which the fifth cell belongs; and sending, by the network element which the fifth cell belongs, the physical identifier of the second cell to the network element to which the first cell belongs.
