Method and apparatus for performing a selective IP traffic offload procedure


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.
