| 发明名称 | Method and apparatus for verifying release of LIPA PDN connection in wireless communication system | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method for verifying, by a mobility management entity (MME), a release of a local IP access (LIPA) packet data network (PDN) connection in a wireless communication system, the method comprising: receiving a handover preparation message from a source home eNodeB (HeNB); upon receiving the handover preparation message, starting a timer; upon receiving the handover preparation message, verifying whether the LIPA PDN connection has been released or not; if the LIPA PDN connection has been released already, performing a normal handover procedure; and if the LIPA PDN connection has not been released, transmitting a handover preparation failure message to the source HeNB, wherein the release of the LIP PDN connection is verified when a deactivate EPS bearer context accept message is received from the source HeNB before the timer expires. | ||
