20120110192 | LIGHT WEIGHT PROTOCOL AND AGENT IN A NETWORK COMMUNICATION - Systems and methods are provided for using a light weight protocol (LWP) and protocol agent in a network communication system. A protocol agent receives a message in LWP from an end node. The message in LWP is directed to a destination network node that uses a network protocol that the end node is incapable of supporting, such as Hypertext Transfer Protocol (HTTP), Real Time Streaming Protocol (RTSP), Session Initiation Protocol (SIP) or other network protocols. The protocol agent determines a network protocol to map the message to, and generates a message in the determined network protocol based on the received LWP message. The protocol agent then sends the generated message to the destination network node. | 05-03-2012 |

The application layer message may be conveyed in a hypertext transfer protocol (HTTP) or a constrained application protocol (CoAP). Embodiments contemplate communicating the application layer message to a server, which may serve as a caching and/or buffering proxy. | 06-14-2012 |
20130103842 | METHODS, SYSTEMS AND APPARATUSES FOR APPLICATION SERVICE LAYER (ASL) INTER-NETWORKING - Systems and/or methods for providing internetworking among application services layers (ASLs) of different network technologies may be provided. For example, a tunnel anchor point (TAP) may be established. The TAP may be configured to enable communication between a local application in the network and a remote application in a different network. At the TAP, an ASL tunnel may be created to the local application in the network to facilitate the communication. Additionally, a message from the local application may be received where at least a portion of the message may be configured to be provided to a remote ASL and the remote application in the different network to which the local application wishes to communicate. At least the portion of the message may be provided to the remote ASL and the remote application in the different network. | 04-25-2013 |

The method may also include the WTRU acting as a gateway for at least one other device in the shared context group. The request to establish or modify the PDP context may be an attach request. The indication that the WTRU is a member of shared context group may be a group identifier (ID). | 06-20-2013 |
20130215782 | MEDIA INDEPENDENT MULTI-RAT FUNCTION IN A CONVERGED DEVICE - A communication device facilitates a multiple radio access technology (multi-RAT) mesh network and includes a processor that executes a media independent mesh function (MIMF), the MIMF configured to exchange media independent mesh information between peer mesh entities. At least two physical network links of the communication device support different radio access technologies (RATs). The MIMF is further configured to determine a RAT-agnostic link quality estimate for a signal routing, to selectively activate or deactivate each RAT-based physical network link to conserve power and control bandwidth; and to determine a multi-RAT mesh capability of a peer device. | 08-22-2013 |
20130329653 | INTERFACE OF AN M2M SERVER WITH THE 3GPP CORE NETWORK - An M2M Server may be integrated into a 3GPP network. A network node, for example a Serving General Packet Radio Service (GPRS) Support Node (SGSN) may include a dedicated interface with a M2M server. The interface may be called a GM2M interface. The interface may be a logical interface internal to the network node. The node may receive subscriber data and control data, wherein the control data facilitates a network control procedure and the subscriber data identifies a device involved in the network control procedure. The node may determine that the device involved in the network control procedure is a machine to machine device based on the subscriber data. The node may also send the control data to a machine to machine server using a message sent via a dedicated interface with the machine to machine server. | 12-12-2013 |
20130336222 | Machine-To-Machine (M2M) Interface Procedures For Announce and De-Announce of Resources - Systems, methods, and instrumentalities are disclosed to propagate announcement and de-announcement of a resource across one or more networks. A first entity, which may be a hosting service capability layer (SCL), may receive a request from an issuer to announce a resource. The first entity may create a representation of the resource. The representation may be referred to as an announced resource. The first entity may send an announce resource request to a second entity (e.g., an announced-to SCL), which may be registered with the first entity. The announce resource request may be sent over an mid interface. The first entity may receive a first response from the second entity over the mid interface indicating that the second entity created the announced resource. | 12-19-2013 |

20140169306 | METHOD FOR SENDING AN ACKNOWLEDGEMENT TO AN INGRESS MESH POINT IN A MESH NETWORK AND A MEDIUM ACCESS CONTROL FRAME FORMAT - The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point. | 06-19-2014 |
