These capabilities enable virtualization of a service subscriber and the physical IoT devices, applications, data and authorized users of the subscriber into a software profile that is representative of the subscriber. Once virtualized, a service subscriber may then delegate the complexities and burden of service enrollment to an automated IoT service enrollment software function.

Abstract: A system and apparatus for addressing the different types of mobility of a wireless transmit/receive unit (WTRU) in a network. A radio access network (RAN) may send a request for configuration information to a gateway device including a device ID of a WTRU, a service ID, and a RAN address. Once the RAN receives configuration information from the gateway device including a forwarding table, the RAN may be prepared to receive non-IP data from a WTRU including a routing tag. The routing tag may be based on the device ID of a WTRU and service ID. The RAN may transmit the non-IP data received from the WTRU to the gateway device over a routing path based on the routing tag and a forwarding table where the non-IP data is forwarded on to its detention, such as another WTRU or an Application Server.

Abstract: A WTRU may initiate access for a PDU session over multiple access networks. The WTRU may register with two or more access networks. For example, the WTRU may register with a 3GPP access network (e.g., LTE Advanced) and a non-3GPP access network (e.g., Wi-Fi). The WTRU may determine to request a multi-access PDU session for a (e.g., at least one) PDU session. A multi-access PDU session may correspond to a PDU session where the WTRU communicates one or more PDUs associated with the PDU session over the 3GPP access network and one or more PDUs associated with the PDU session over the non-3GPP access network. The WTRU may receive a confirmation message indicating that a multi-access PDU session has been established. The WTRU may send uplink data over the 3GPP access network and the non-3GPP access network, e.g., in accordance with the established multi-access PDU session.
