    Abstract: Systems, methods, and instrumentalities may implement service-based discovery in a network, such as a 3GPP or 3GPP2 network. A Discovery Server may be used to query and find services offered by the network or by entities that interface with the network. Situational context information or policy information, or both, may be communicated to the discovery server so that the Discovery Server can provide context-aware and policy-based discovery services. The Discovery Server may be used to control which of the entities that interface with the network can discover one another. The Discovery Server may support queries based on, for example, the type of MTC entity, the type of services hosted on the entity, the availability times of the entity, types of protocols supported, levels of Quality of Service (QoS) supported, and MTC-IWF services.

    Abstract: A method for supporting proxy mobile internet protocol (PMIP) in a local mobility anchor (LMA) is described. The method includes receiving a request for multicast information corresponding to a request for multicast services from at least one of a plurality of wireless transmit/receive units (WTRUs) which require multicast services associated with a multicast group. The method also includes transmitting, to a mobile access gateway (MAG) via an aggregated multicast tunnel, multicast information for distribution to at least one of the plurality of WTRUs in the multicast group. The multicast information comprises an IP address corresponding to the multicast group.

    Abstract: Methods and systems providing application layer support for one or more sleeping nodes in constrained networks are contemplated. Embodiments contemplate inserting sleep information in a header option or payload of an application layer message. 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.

    Abstract: A method and apparatus are described for providing triggering services over multiple access networks. A triggering service server (TSS) architecture includes a triggering identity function (TIF) which maintains a database of device and application identifier mappings across multiple access networks, triggering capabilities and triggering preferences. The TSS also includes a triggering decision function (TDF) that uses information from the TIF and determines how triggers should be performed towards a device and/or an application hosted on a particular device. The TSS also includes triggering gateways (T-GWs) that perform triggering in different domains. A “not-registered-triggerable” state may be used to indicate whether an entity, such as a device, application or user can receive triggers although it is not registered in a specific access network. Methods and apparatus are also described for implementing various unassisted triggering and assisted triggering procedures using wireless transmit/receive units (WTRUs), application servers (ASs) and service capability servers (SCSs).

    Abstract: Methods and apparatuses for capillary network device registration implemented in a wireless transmit/receive unit (WTRU) are disclosed. Registration or bootstrap messages may be received by a capillary network device where the WTRU acts as a gateway for communication between the capillary device and a network such as a 3GPP network. A capillary network device identifier (CNDID) is sent to the capillary device. A packet data protocol (PDP) context or PDN connection may be established with the network and the CNDID may be sent to a machine type communications (MTC) server. The WTRU may create the registration message, establish a connection with the network, and forward the registration message to the MTC server. Methods and apparatuses implemented in a network are also disclosed for identifying, addressing, and triggering the capillary devices from the MTC server. The trigger message may include fields for group communication, reducing signaling, and enabling charging.
