A source base station transmits a handover requirement message, for a handover to a destination base station of a user equipment (UE), to a source base station gateway. When a handover command message indicating performing of the handover to a destination base station of the UE is received from the source base station gateway, the handover command message is transmitted to the UE. When a UE context release command message is received from the source base station gateway, a context of the UE is released. And a UE context release completion message, representing that the context of the UE is released, is transmitted to the source base station gateway. The handover requirement message includes a Next-hop Chaining Counter (NCC) and an encryption key for a communication between the UE and the destination base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for performing handover","description":"A method and an apparatus perform a handover using the X2 interface.
