Abstract
In an inter-master eNB (MeNB) handover procedure without secondary eNB (SeNB) change, a user equipment (UE) receives a SeNB kept indicator indicating that a SeNB has been kept successfully from a source MeNB. Upon receiving the SeNB kept indicator, the UE determines that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change, and skips the random access procedure to the SeNB.
Claims12
A method for skipping a random access procedure to a secondary eNodeB (SeNB), by a user equipment (UE), in an inter-master eNB (MeNB) handover without SeNB change in a wireless communication system, the method comprising:
- receiving, by the UE, a SeNB kept indicator indicating that a SeNB has been kept successfully in the inter-MeNB handover without SeNB change from a source MeNB;
- determining, by the UE, that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change according to the SeNB kept indicator;
- and
- skipping, by the UE, the random access procedure to the SeNB.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor, coupled to the memory and the transceiver, that:
- controls the transceiver to receive a secondary eNodeB (SeNB) kept indicator indicating that a SeNB has been kept successfully in an inter-master eNB (MeNB) handover without SeNB change from a source MeNB,
- determines that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change according to the SeNB kept indicator, and
- skips a random access procedure to the SeNB.
