Abstract: Methods, systems, and apparatuses for protocol data unit (PDU) session management over different access technologies (ATS) are disclosed. A wireless transmit/receive unit (WTRU) may receive a first message from a network over a first access technology. The first message may include an indication for the WTRU to reestablish resources for one or more protocol data unit (PDU) sessions over a second access technology. The WTRU may determine that a PDU session of the one or more PDU sessions is locally deactivated by the WTRU. The WTRU may send a second message via the first access technology. The second message may include a PDU session status information element (IE) indicating the PDU session is locally deactivated such that the network releases the PDU session.

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: Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

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: In an evolved UMTS terrestrial radio access network (E-UTRAN), paging may be performed using an international mobile subscriber identity (IMSI) or S-temporary mobile subscriber identity (S-TMSI). With the paging, a wireless transmit/receive unit (WTRU) may send an extended service request message to the E-UTRAN and perform circuit switched (CS) fallback.

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: 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: Systems, methods, and instrumentalities are provided to determine routing associated with a short message. A SMS-SC may send a first routing request to a home subscriber server (HSS). The first routing request may be associated with the short message. The SMS-SC may receive a first routing reply. The first routing reply may include one of an indication that the short message is associated with a service capability server (SCS) or a first control plane routing associated with the short message. The SMS-SC may send the short message to an SCS serving node. The first routing reply may include the indication that the short message is associated with a service capability server (SCS). The SMS-SC may send a second routing request to a SCS subscription database. The SMS-SC may receive a second routing reply from the SCS subscription database, which may indicate a second control plane routing for the short message.

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.
