摘要： Methods, devices, and systems related to serving gateway extensions for inter-system mobility in integrated small Cell and WiFi networks. An SGW may be extended into a common intermediate gateway for both LTE and WiFi access. A GTP-based “SI a” interface between a TWAN and an SGW is introduced. The STa interface between TWAN and 3 GPP AAA server/proxy is extended to enable selection of an SGW for establishment of the disclosed S1a interface. The extended SGW and protocols may be used to optimize inter-system mobility between LTE small cells and trusted WiFi. SGW and PDN Gateway (PGW) functionality is disclosed to support GTP-based IP flow mobility via multi-access (LTE and WiFi) connectivity to the same packet data network (PDN). Non-access stratum (NAS), EAP, and GTP-C protocols may also be extended to include a “multi-connection” indication in addition to existing “handover” indication.

摘要： Various issues with existing congestion and overload control mechanisms are recognized and described herein. Described herein, in accordance with various embodiments, are various mechanisms in which core networks, such as 3GPP networks for example, and an M2M service layer can coordinate and share information to efficiently and intelligently manage each other's congestion and overload states.

摘要： A Policy and Charging Enforcement Function (PCEF) can be aware of whether a UE connects through a cellular or WIFI connection through a gateway. Management messages can be modified to allow the PCEF volume based online charging functionality to remain in the core network (i.e. in the P-GW/PCEF). Session management messaging between the ISWN (ISW-GW) and the core network (P-GW/PCEF) may be modified so that the core network may be notified when the ISWN moves a bearer, or flow, from one RAT to another. Alternately, PCEF volume based online charging functionality can be added to the ISWN. The PCEF of the ISWN can be tasked with performing volume based online charging while the UE is in the ISWN.

摘要： An Application Data Delivery Service (ADDS) facilitates application data transfer between applications that may reside in a device domain (e.g., M2M/MTC devices and gateways) and applications residing in a network domain (e.g., an AS or SCS). The ADDS leverages existing 3GPP transport mechanisms, such as NAS, SMS, USSD, and User Plane, and it is configured to select a transport mechanism for delivering application data based on criteria, such as application data characteristics, application/end node characteristics and availability, subscription information, policies of the network, network conditions (such as congestion, node availability) and the like.

摘要： Methods, devices, and systems allow for bootstrapping of a machine-to-machine device. In an embodiment, a bootstrap erase architecture allows the machine-to-machine server to manage bootstrap erase policies, detect access network specific events, initiate a bootstrap erase based on these policies and events, and allow for machine-to-machine server handover. A device or gateway service capability layer (182) requests its network service capability layer to fetch data that the device or gateway previously stored on a different network service capability layer (196, 197). In an embodiment, when bootstrap erase is performed because the network service capability layer can no longer provide service to the device or gateway, the network service capability layer may recommend other NSCLs to the device or gateway. In another embodiment, a bootstrap erase procedure may be modified so that temporary identifiers may be assigned for a next bootstrapping event.

摘要： The present application is at least directed an apparatus including a non-transitory memory and a processor that is operably coupled to the non-transitory memory for managing a server transition with a service for user equipment (UE). The processor is configured to perform the instructions of receiving, at a core network, a first request from a first server to switch responsibility of the service to a second server to communicate with the UE. The processor is also configured to perform the instructions of determining a first core network terminating point needs updating to a second core network terminating point. The processor is further configured to perform the instructions of selecting the second core network terminating point sends a result of the determination to the user equipment. The processor is still further configured to perform the instructions of sending, to the service, a notification the user equipment is associated with the second core network terminating point. The processor is still yet even further configured to perform the instructions of transmitting, to the UE, a second message notifying the UE characteristics of a session have changed.

摘要： Service layer and application triggering may be used in a machine-to-machine environment. In an embodiment, an existing service layer procedure, such as registration, may allow a device or gateway service layer or application to indicate to a machine-to-machine server what port is listened to for triggers. In another embodiment, triggering may be used to provide bootstrapping instructions, including temporary bootstrapping identifiers, in trigger requests. In another embodiment, triggering may be used to assist with event notification. Service layer or application instructions may be embedded inside of trigger payloads. A trigger payload format is defined.

摘要： The present application describes a user equipment including a processor and a memory, where the memory stores computer-executable instructions that, when executed by the processor, cause the user equipment to perform a set of instructions. The instructions include transmitting, to a network, a message requesting to modify or establish flow that is not to be charged to the user equipment. The instructions also include receiving, from the network, an indication based on the message request. The instructions further include determining, based on the indication, whether to make the flow being associated with the message.
