Method and apparatus for performing a selective ip traffic offload procedure

A method of a wireless transmit/receive unit (WTRU) performing a selected Internet protocol (IP) traffic offload (SIPTO) procedure, the method comprising:

• establishing a first packet data network (PDN) connection with a first gateway;
• receiving local network SIPTO policies in response to at least one query;
• establishing a local PDN connection to a local gateway based on the local network SIPTO policies;
• and
• routing IP flows from the first PDN gateway to the local PDN connection.

A network node comprising:

• a receiver configured to receive a first packet data network (PDN) connectivity request from a wireless transmit/receive unit (WTRU) to establish a first PDN connection between the WTRU and a first gateway;
• a processor configured to make a determination to perform a selected Internet protocol (IP) traffic offload (SIPTO) at a local network;
• and
• a transmitter configured to send a message instructing the WTRU to perform a PDN release and reconnection procedure, wherein the first PDN connection is released and a second PDN connection for SIPTO is established between the WTRU and a second gateway.
