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.
Abstract:
Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.
Abstract:
Methods, apparatus and systems using Enhanced Dedicated Core Network (DCN) selection are disclosed. One representative method includes receiving, by the core network entity from another core network entity, information indicating that a DCN type is new or has change for a wireless transmit/receive unit (WTRU); and sending a message, by the core network entity to the WTRU, including a new or a changed DCN type.
Abstract:
Methods and apparatuses for redirecting a wireless transmit/receive unit (WTRU) to a dedicated core network (CN) node are described. An apparatus is configured to initiate a Service Request with a non-dedicated network node. The apparatus is configured to receive a special identifier in response to the Service Request, which indicates the apparatus should be redirected to a dedicated CN node based on subscription information. Radio access network resources associated with the apparatus may be released and the apparatus may then perform a tracking area update (TAU) request which is then forwarded to the dedicated CN node.

Abstract:
Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message. In addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.
Abstract:
A method and apparatus for supporting machine-type communications (MTC) are disclosed. A wireless transmit/receive unit (WTRU) may configure itself to operate in a mobile-originated-only mode. The WTRU may perform no, or a subset of, radio resource control (RRC) idle and/or non-access stratum (NAS) idle/standby state procedures in the mobile-originated-only mode. For example, the WTRU may perform cell reselection but not paging monitoring in the mobile-originated-only mode. Alternatively, the WTRU may perform paging monitoring but not cell reselection and location update. The operation in the mobile-originated-only mode may be triggered explicitly or implicitly. For example, the WTRU may operate in the mobile-originated-only mode if an inactivity timer expires. The WTRU may switch the mode in accordance with a pre-configured schedule. After transition of the operation mode, the WTRU may send a message to the network indicating such mode switch.
Abstract:
Methods, apparatus, and systems are disclosed for handover of a Wireless Transmitter/Receiver Unit (WTRU) moving between a local network and another network. The WTRU established a local IP access (LIPA) session in the local network via a first Access Point (AP). The method includes receiving, by a second AP in the other network, a request to connect to the other network; and transitioning the LIPA session in the local IP network to a managed remote access (MRA) session in the other network. The transitioning includes establishing a path between the first AP and the second AP via a gateway, and informing the gateway of the transition to the MRA session.
Abstract:
Method and apparatus efficiently signal and use resources for wireless communications supporting circuit switched (CS) and packet switched sessions (PS). Signaling and interaction between the wireless transmit/receive unit (WTRU), and various network entities, such as the Mobility Management Entity (MME), the Visitor Location Register (VLR), and Base Stations (BS), are used to implement circuit switched fall back (CSFB) in a PS system.
