Title: METHOD AND APPARATUS FOR UE MOBILITY IN A SMALL CELL SYSTEM
Abstract:
The present application discloses a method for a master eNB (MeNB) handover or a secondary eNB (SeNB) handover in a small cell system, comprising: sending by a source MeNB information of a source secondary cell (Scell) to a target MeNB; sending by the target MeNB a message to the source MeNB, the message notifying the source MeNB to suspend data transmission on a bearer of the SeNB. Until a message of data transmission resuming is received, the data transmission/reception is started to continue. The method for a MeNB handover or a SeNB handover provided in the present application may reduce the reconfiguration of the bearer for the UE, avoid releasing the bearer by error, and improve the system throughput and the data rate of transmission.
