Abstract:
The present invention relates to a method and apparatus for managing a Local IP Access (LIPA) connection in a local network system. The method of managing a LIPA connection of UE in a connected state according to an embodiment of the present invention includes the steps of: a source home base station for UE determining a handover of the UE; when the handover of the UE is determined, determining whether a target home base station is a Long Term Evolution (LTE) release 10 or a Pre Rel-11 HeNB; and when the target home base station is a Pre Rel-11 HeNB, disconnecting the LIPA connection of the UE. According to an embodiment of the present invention, the mobility of UE having a LIPA PDN connection can be efficiently controlled in a local network where a Rel-11 H(e)NB and a Pre Rel-11 H(e)NB exist together.
