Abstract: A Mobility Management Entity (MME) comprises at least one entity or layer having Mobile Switching Center (MSC) functionality to support a Short Messaging Service (SMS) between a network and a mobile station by employing Machine-to-Machine (M2M) or Machine Type Communication (MTC) protocols. A first state machine entity or layer that supports relay functions to perform forwarding of SMS messages to the mobile station. A second state machine entity or layer that supports connection functions with at least an HSS/HLR (Home Subscriber Server/Home Location Register), and with an SMS-SC (Short Messaging Service-Service Center) or GMSC/IWMSC (Gateway MSC/Interworking MSC).

Abstract: A Mobility Management Entity (MME) having MSC functionality implemented therein, performs a scheme of MTC device triggering has been conceived. A PS and CS combined location update is sent to the HSS/HLR by means of piggybacking of CS domain information over an interface between the MME and the HSS/HLR as part of a “combined” EPS/IMSI attach procedure or a “combined” TA/LA update procedure. The, SMS signaling is received from an SMS-SC (GMSC/IWMSC) to transfer an SMS message for an LTE-only device or a single-mode E-UTRAN device. Here, the SMS signaling is received from the SMS-SC (GMSC/IWMSC) via an interworking function (IWF) that provides interworking between a MAP interface and a Diameter interface. As a result, M2M or MTC devices can be supported for an LTE network or the like.

Abstract: The present invention relates to a mobile communication system, and more particularly relates to a method for transmitting a small-sized control signal (also known as “small data”) using a control plane in a MTC (machine-type communication) service in a mobile communication system. In the present invention, MTC data is encapsulated in an existing control procedure or control message or the like, on a control signal, without performing packet data bearer setup, and the control signal having the encapsulated MTC data is sent between a network and a terminal, thereby optimizing network resource efficiency and reducing the wireless channel load.

Abstract: Technology that allows PDN connections for a UE to be resumed efficiently after WLAN connectivity is lost and then regained are disclosed. A UE can have a multi-legged or multi-access packet-data-network (PDN) connection that is used to communicate with a WLAN and with an eNB. When WLAN connectivity is lost, the UE can send a WLAN-connectivity-loss communication to a PDN-GW via the eNB. A TWAG can also detect that the UE's WLAN connectivity has been lost and can send a suspension communication to the PDN-GW. The TWAG can also store PDN context information for the UE for a predefined period of time. When the UE regains WLAN connectivity, the UE can send a WLAN-link-control-protocol (WLCP) communication to the TWAG indicating that the UE wishes to resume one or more PDN connections that were previously suspended.

Abstract: Embodiments of system and method configurations for device discovery and connection establishment in connection with use of device-to-device (D2D) and proximity-based services are generally described herein. In some examples, an evolved packet core (EPC) of a 3GPP Long Term Evolution or 3GPP Long Term Evolution-Advanced (LTE/LTE-A) network is arranged to assist D2D identification and discovery procedures at user equipment (UEs) connected to the LTE/LTE-A network. Various identification and discovery procedures may be implemented in connection with proximity detection and the establishment of communication times for the establishment of the D2D communication link, between the UEs. Accordingly, the EPC of the LTE/LTE-A network may assist the establishment of a device-to-device communication link between UEs on a wireless network employing a distinct wireless protocol (for example, a direct wireless network connection via a wireless local area network (WLAN) or wireless personal area network (WPAN)).

Abstract: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.

Abstract: System and techniques for secure direct discovery UEs are described herein.

Abstract: A node is provided that includes a home base station collocated with a local gateway (L-GW) providing access to a local Internet Protocol (IP) network. The node performs an establishment procedure with a security gateway (SeGW), and discriminates a packet. The node uses a first interface configured at the L-GW and a second interface which is configured between the home base station and a gateway for the home base station. The first and second interfaces are tunneled through a same IP security (IPsec) tunnel opened between the home base station and the SeGW. The home base station for the first interface uses a first IP address that is either same as or different from a second IP address used by the home base station for the second interface. The node uses either distinct ranges of Tunnel Endpoint Identifiers (TEIDs) or the first and second IP addresses to discriminate the packet.

The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.

User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized.

The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.
