Abstract: A processing device such as a server implementing smart building agent functionality is located on an external network and is configured to communicate with a BAS located on a building's internal network. Communication between the processing device and the BAS occurs over a first communications channel. The processing device can be configured to receive sensor data from various sensors that might otherwise not be supported by the existing BAS. Communication between the sensors and the processing device occurs over a second communications channel different from the first communications channel. The processing device can generate control commands based on the received sensor data that provide instructions to the BAS for adjusting an operation parameter for one or more of the building systems and/or equipment. This control command can be sent to the BAS through the first communications channel.

Abstract: A subscription analyzing and grouping mechanism can group similar subscription requests from different subscribers and generates an aggregated notification for them. The subscription analyzing and grouping mechanism reduces the number of subscription request messages and notification messages and in turn improves subscription efficiency and makes M2M/IoT service layer more efficient and scalable.

Abstract: A node availability estimation service can be used at a service layer of an M2M/IoT network. Value-added services can leverage this node availability information to improve the operation intelligence, quality of service, communication overhead as well as energy efficiency for M2M/IoT systems. A Real-time Data Collection (DC) component can collect real-time data from input sources at service layer (e.g., other existing CSFs). A Data Processing for Estimating Node Availability component (DP) can execute data processing for estimating node availability based on the data collected by DC. A Node Availability Service Provisioning component (SP) can store the estimated node availability results from DP and expose them to service clients in terms of “node availability estimation services”.

Abstract: A machine to machine (M2M) service layer can facilitate acquiring and providing location information for use by M2M devices. The service layer can also ensure that privacy controls are maintained and enforced for location information. A device can report its location and its privacy preferences to a service layer device. Other devices can receive this location information subject to qualifying to receive it based on the privacy preferences. Devices in an area may advertise services with the service layer acting as a filter and relay point ensuring that such advertisements satisfy the privacy policies of the devices involved.

Abstract: Methods are proposed to integrate MQTT Server functionality into the oneM2M CSE, as well as to interconnect such CSE-based MQTT Servers into a network organized around a topic structure based on resource address. Methods can dynamically allocate, assign and deliver an identifier that can be used as the AE-ID by the AE, CSE and MQTT Server. The MQTT Server can be internetworked into the M2M Service Layer such that an MQTT Server is available in every Service Layer node that hosts a CSE.

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: 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.
