Abstract
Methods and apparatus are described. A mobility management entity (MME) includes an interface and a processor. The interface receive a packet data network (PDN) connectivity request from a wireless transmit/receive unit (WTRU) for use in local Internet protocol access (LIPA)/selected Internet protocol offload (SIPTO), wherein the PDN connectivity request includes an access point name (APN). The processor determines, in response to the received PDN connectivity request, whether LIPA/SIPTO access is permitted. The processor also establishes, in response to the received PDN connectivity request, a PDN connection between the WTRU, local gateway, serving gateway (SGW) and packet data network gateway (PDN GW) so that at least a portion of uplink/downlink data is transferred using LIPA/SIPTO.
