Method and apparatus for selected internet protocol (IP) traffic offload (SIPTO) and local IP access (LIPA) mobility

A wireless transmit/receive unit (WTRU) comprising:

• a receiver configured to receive a service from a Local Gateway (L-GW) via a first base station (BS), wherein the first BS belongs to a Local Home Node B (HNB) Network (LHN);
• a memory configured to store an LHN list that includes information related to at least the LHN;
• the receiver configured to receive a message that includes information related to the LHN and information indicating whether a second BS is capable of providing the service from the L-GW, wherein the second BS belongs to the LHN and is configured to communicate with the L-GW;
• a processor configured to determine whether the second BS services a Closed Subscriber Group (CSG), to which the WTRU is a member, based on a broadcasted CSG identifier (ID) being included in a list of allowed CSG IDs stored in the WTRU;
• the processor configured to perform a handover to the second BS based at least on the LHN list and the received message;
• and
• the receiver configured to receive the service from the L-GW via the second BS.

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

• receiving a message that includes:
• a Local Home Node B (HNB) Network (LHN) ID that identifies an LHN;
• and
• a Local Internet Protocol (IP) Access (LIPA) indication that indicates whether the LHN supports LIPA services;
• selecting to a cell that belongs to the LHN on a condition that the LHN ID is included in a list of allowed LHNs stored in the WTRU and that the LIPA indication indicates that the LHN supports LIPA services;
• determining whether the cell services a Closed Subscriber Group (CSG), to which the WTRU is a member, based on a broadcasted CSG identifier (ID) being included in a list of allowed CSG IDs stored in the WTRU;
• and
• receiving a service from the cell.
