Abstract
The invention claims for a home node B (HNB) mobility of local IP access (LIPA) packet data network (PDN) connection of the method and device. the target home node B (HNB) can be removed from the source HNB receives a switching request message of a wireless transmit/receive unit (WTRU). in response to the handover request message a path switching request may be sent to the local gateway (LGW) to the downlink data path to the target HNB. the LGW as the local mobility anchor for mobility management and switching and notifies the HNB gateway (GW) the switching such that a downlink data path for traffic of the core network (CN) is changed to the target HNB.
A method and apparatus for home Node-B (HNB) mobility with a local IP access (LIPA) packet data network (PDN) connection are described. A target home node-B (HNB) may receive a handover request message from a source HNB to handover a wireless transmit/receive unit (WTRU). A path switch request may be transmitted to a local gateway (LGW) to change a downlink data path towards the target HNB in response to the handover request message. The LGW may act as a mobility management and local mobility anchor for the handover; and informing an HNB gateway (GW) about the handover so that the downlink data path for core network (CN) traffic is modified towards the target HNB.
