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.

Claim
1. A mobility management entity (MME) comprising:
an interface configured to 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); a processor configured to determine, in response to the received PDN connectivity request, whether LIPA/SIPTO access is permitted; the processor is further configured to establish, 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.
2. The MME of claim 1, wherein the processor is further configured to send a create session request message to the SGW to establish the PDN connection.
3. A method, implemented by a mobility management entity (MME), the method comprising:
receiving, by the MME, 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); in response to the received PDN connectivity request, determining, by the MME, whether LIPA/SIPTO access is permitted; in response to the received PDN connectivity request, establishing, by the MME, 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.
4. The method of claim 3, further comprising sending, by the MME, a create session request message to the SGW to establish the PDN connection.
