Abstract:
A method and apparatus for verifying a release of a local IP access (LIPA) packet data network (PDN) connection in a wireless communication system is provided. A mobility management entity (MME) receives a handover preparation message from a source home eNodeB (HeNB), verifying whether the LIPA PDN connection has been released or not on receiving the handover preparation message. If the LIPA PDN connection has been released already, the MME performs a normal handover procedure. If the LIPA PDN connection has not been released, the MME transmits a handover preparation failure message to the source HeNB.
