A computing device is disclosed. The computing device comprises processing circuitry that is configured to expose () a resource that is hosted at the computing device, wherein the resource comprises a digital interface for a physical entity to which the resource corresponds, and expose () information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds. Also disclosed is a network node, the network node comprising processing circuitry that is configured to discover a resource that is hosted at the computing device, and to discover information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds. The processing circuitry is further configured to prepare an action relating to the physical entity corresponding to the resource on the basis of a current state of the resource and the information, and to initiate execution of the prepared action.

Computing device, network node, and methods thereof

A technique for generating an internet protocol, IP, address according to IPv6, for access to one of a plurality of wireless devices connected or connectable to a wireless network from an application node in a communications network is provided. As to a method aspect of the technique, an IPv6 address for access from the application node in the communications network to a respective one of the wireless devices is generated based on a subnet identifier of the wireless network and a device identifier of the respective one of the wireless devices. The generated IPv6 address is provided for the access from the application node in the communications network.

Generating or providing IPV6 addresses

Methods of a Lightweight Machine to Machine (LwM2M) device and of an LwM2M managing device of controlling transmission of data in a network. A method of an LwM2M device is provided of for controlling transmission of data in a network includes sending a message having data towards an intended receiver. The message includes information indicating a maximum number of hops allowed for the message, thereby allowing a node in the network receiving the message at each hop to update a hop counter and further to discontinue forwarding of the message towards the intended receiver when the hop counter indicates that the maximum number of hops has been reached. The method includes receiving, from the node, an indication that the hop counter has reached the maximum number of hops and sending, to an LwM2M managing device, information indicating that the hop counter has reached the maximum number of hops.

Controlling transmission of data in a network

A sending node is disclosed that is operable to provide a representation of at least one resource, wherein the resource comprises a sensor measurement, and wherein the representation is operable for transmission using an Internet of Things (IoT) transfer Protocol. The sending node comprises processing circuitry configured to generate () a representation of the resource according to a data model, generate () a Real-time Transport Protocol (RTP) data packet, wherein the RTP data packet comprises the generated representation of the resource, and send () the generated RTP packet to a receiving node. Also disclosed are a receiving node and an intermediate node.

Devices and methods for provision of resource representations

Methods for operating a device, a Bootstrap server and a network node are disclosed. The method for operating a device includes requesting a Bootstrap data object from a node reachable via the network, the Bootstrap data object including an identification of a device management server, receiving a Bootstrap data object from a node reachable via the network, configuring a data object on the device in accordance with the received Bootstrap data object, and requesting registration with the device management server identified in the received Bootstrap data object. Also disclosed are a device, a Bootstrap server and a network node.

Methods for operation of a device, bootstrap server and network node

A method of operating a user equipment, UE, that is operating in a network includes determining whether the UE and/or an application that is running on the UE is using or planning to use an early data transmission, EDT, to transmit sensor data via the network. Operations include responsive to determining that the UE and/or the application that is running on the UE is using or planning to use the EDT, informing the application of configuration parameters corresponding to the EDT and altering, by the application and based on the configuration parameters corresponding to the EDT, properties of the sensor data that is provided to the UE for transmission to the network to include revised sensor data.

Sensor-data batching for efficient early data

A method of re-establishing a connection between a LWM2M client and an LWM2M server following a reconnection of the LWM2M client to the LWM2M server includes determining, at the LWM2M client, a state of the LWM2M client device prior to reconnection of the LWM2M client, transmitting, to the LWM2M server, an indication of the state of the LWM2M client prior to reconnection of the LWM2M client, and receiving a response from the LWM2M server indicating whether the indicated state of the LWM2M client is an expected state or an unexpected state of the LWM2M client.

LWM2M client state synchronization

There is provided mechanisms for configuring an MQTT client node with a topic prefix. A method is performed by the MQTT client node. The method comprises sending a request to a DHCP server for configuration. The method comprises receiving a response from the DHCP server. The response comprises configuration information and at least one prefix string defining the topic prefix to be used together with a topic by the MQTT client node when publishing data on said topic.

Topic handling in MQTT networks

A method by a management node for managing a device operable to join a network includes receiving from the device a request to join the network, the request including a device specific parameter and a token, and generating an authentication parameter from the device specific parameters and the token. The method further includes authorising the device to join the network if the authentication parameter fulfils a validity criterion. Generating an authentication parameter from the device specific parameters and the token includes generating an input including the device specific parameters and the token, computing a cryptographic function of the generated input, and setting an output of the cryptographic function as the authentication parameter. Also disclosed are a method for operating a device, a management node, a device and a computer program.

Management of devices joining a network

A method is disclosed for managing notifications about a resource exposed by a computing device. The method, performed by a node, comprises sending a message to the computing device, the message registering the node for notifications about the state of the resource and specifying, in a message to the computing device, a limitation on a notification payload size, the limitation applicable to notifications about the state of the resource. Also disclosed are a method performed by a computing device, a node, a computing device and a computer program product.

Managing resource state notifications

Methods may be provided to transmit encrypted data from a communication device to a remote storage system. A data value and information related to the data value may be provided, where the information related to the data value includes an identifier associated with the communication device and a time-value associated with the data value. A combination of the time-value and the identifier may be encrypted using a public key to provide a first encrypted value. The data value may be encrypted using the public key to provide a second encrypted value, and a hidden datum package may be generated including the time-value, the first encrypted value, and the second encrypted value. The hidden datum package including the time-value, the first encrypted value, and the second encrypted value may be transmitted to the remote storage system.
