Abstract:
A method and apparatus are described for handling local Internet protocol (IP) access (LIPA) connection during circuit switched fallback (CSFB) and handover (HO). One representative method of managing a Local Internet Protocol Access (LIPA) packet data network (PDN) connection to a wireless transmit/receive unit (WTRU), includes performing a switching operation to switch from the LIPA PDN connection to a non-LIPA PDN connection for communication to the WTRU; and suspending the LIPA PDN connection, in response to the switching operation.
