Abstract
A method and apparatus are described for performing a selected Internet protocol (IP) traffic offload (SIPTO) procedure. A network node (e.g. a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN)) may receive a packet data network (PDN) connectivity request from a wireless transmit/receive unit (WTRU). A determination may be made to perform SIPTO at a local network and the WTRU may perform a PDN release and reconnection procedure. The determination may be based on at least one of a closed subscriber group (CSG) identity (ID) a home evolved Node-B (HeNB) ID or a local network ID. An access network discovery and selection function (ANDSF) may be queried for IP interface selection (OPIIS) rules a local access point name (APN) that supports per flow SIPTO at a local network and IP flows that may be routed to the local APN.

Claim
1. A method of a network node performing a selected Internet protocol (IP) traffic offload (SIPTO) procedure, the method comprising:
receiving 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, wherein the first PDN connectivity request includes an access point name (APN); and
for the requested APN, selecting between one of activating SIPTO at a local network and activating SIPTO above radio access network (RAN),
wherein the activating SIPTO at the local network includes selecting a local packet data network gateway (L-GW) in the local network to use for the SIPTO procedure and the activating SIPTO above the radio access network (RAN) includes selecting a packet data network gateway (PGW) in a macro network to use for the SI PTO procedure.
2. The method of claim 1, further comprising:
on a condition that activating SIPTO at the local network is not selected, deactivating the first PDN connection by signalling a cause value indicating that reactivation of the first PDN connection is requested.
3. The method of claim 1, further comprising:
receiving location information from the WTRU; and
making a determination to activate SIPTO at the local network based on the location information.
4. The method of claim 3, further comprising:
instructing the WTRU to perform a PDN release and reconnection procedure;
receiving a second PDN connectivity request from the WTRU; and
initiating a procedure to release the first PDN connection and establish a second PDN connection for SIPTO between the WTRU and a second gateway in the local network.
5. The method of claim 4, wherein the network node is a mobility management entity (MME) and the second gateway is a local gateway in the local network.
6. The method of claim 4, wherein the network node is a serving general packet radio service (GPRS) support node (SGSN) and the second gateway is a local gateway in the local network.
7. The method of claim 1, wherein the WTRU checks an access network discovery and selection function (ANDSF) for IP interface selection (OPIIS) rules, identifies a local access point name (APN) that supports per flow SIPTO at the local network, and identifies IP flows that can be routed to the local APN.
8. The method of claim 7, wherein the WTRU uses IP flow mobility (IFOM) procedures to offload traffic to the local APN.
9. The method of claim 3, wherein selecting activating SIPTO at the local network is based on at least one of a closed subscriber group (CSG) identity (ID), a home evolved Node-B (HeNB) ID or a local network ID.
10. The method of claim 3, wherein the location information includes a tracking area identity or a home evolved Node-B identity.
11. The method of claim 1, further comprising:
receiving a message indicating that at least one of the WTRU or the SIPTO access point name (APN) is registered as local IP access (LIPA) offload in response to at least one query about LIPA permissions;
instructing the WTRU to reconnect at an offload point; and
establishing a LIPA session.
12. A network node comprising:
a transceiver 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, wherein the first PDN connectivity request includes an access point name (APN); and
a processor, the processor and the transceiver configured to select, for the APN, between one of activating selected Internet protocol (IP) traffic offload (SIPTO) at a local network and activating SIPTO above radio access network (RAN),
wherein the activating SIPTO at the local network includes selecting a local packet data network gateway (L-GW) in the local network to use for a SIPTO procedure and the activating SIPTO above the radio access network (RAN) includes selecting a packet data network gateway (PGW) in a macro network to use for the SIPTO procedure.
13. The network node of claim 12, wherein the processor is further configured to, on a condition that the processor does not select activating SIPTO at the local network, deactivate the first PDN connection by signalling a cause value indicating that reactivation of the first PDN connection is requested.
14. The network node of claim 12, wherein:
the transceiver is further configured to receive location information from the WTRU,
the processor is further configured to select activating SIPTO at the local network based on the location information,
the transceiver is further configured to send a message instructing the WTRU to perform a PDN release and reconnection procedure,
the transceiver is further configured to receive a second PDN connectivity request from the WTRU, and
the processor is further configured to initiate a procedure to release the first PDN connection and establish a second PDN connection for SIPTO between the WTRU and a second gateway in the local network.
