Abstract
Official abstract text for this publication.
A method for handover of User Entity (UE) by a source Base Station (BS) is provided. The method includes determining whether to handover the UE using an X2 interface, transmitting a handover request message to a target BS, the handover request message including Closed Subscriber Group (CSG) information of the target BS, and receiving a handover request acknowledgement message from the target BS, wherein the determining of whether to handover the UE using the X2 interface includes, if there is the X2 interface between the source BS and the target BS, and if the target BS does not support a CSG or the target BS supports a same CSG supported by the source BS, determining to perform the handover of the UE using the X2 interface, and obtaining the CSG information of the target BS through an X2 interface set up procedure.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for a handover of a user entity (UE) by a source evolved node B (eNB), the method comprising: communicating, by the source eNB, with the UE subscribed to a closed subscriber group (CSG) served by the source eNB; determining, by the source eNB, whether an X2-based handover of the UE is to be performed if no access control at a mobility management entity (MME) is required; and if the X2-based handover of the UE is determined to be performed, trans…
