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.

Methods providing transmission and/or searching of encrypted data and related devices

There is provided mechanisms for making resources discoverable. A method is performed by a resource location mapping node. The method comprises acquiring scope information of a local network and location information enabling determination of specific locations of resources in the local network. The method comprises generating Constrained Application Protocol (CoAP) resource identifiers of the resources from the scope information and the location information. The method comprises providing the CoAP resource identifiers to a resource directory, thereby making the resources discoverable.

Discovery of resources in a local network

A method or enabling compression context setup for Internet-of-Thing, IoT, devices in a communication network is presented. The method is performed in an application server node for IoT devices, and includes sending a get context message to a gateway node, the get context message requesting a compression context setup includes compression details for an IoT device, receiving an indication of the requested compression context setup for the IoT device from the gateway node, and compressing and decompressing messages sent to and from the IoT device based on the received indication. An IoT device, a gateway node, an application node, a computer program and a computer program product thereof are also presented.

Compression context setup for data transmission for IOT devices

Systems and methods for increasing the value of trash. By increasing the value of trash, persons have an incentive to collect litter and deposit the collected litter at an appropriate trash collection site (e.g., garbage can, reverse vending machine, recycling center, etc.). In one aspect, a financial instrument (e.g., a Bitcoin, Bitcoin-like value, account identifier, or any other financial instrument) or a pointer to a financial instrument is attached to the object itself or placed inside of the object in a way that is not easily extracted before appropriate time.

Trash collection systems and methods

Embodiments include methods for decompression of headers of received Internet Protocol (IP) packets, such as by a device. Such methods include receiving a single transmission unit that includes a bitmap comprising a plurality of bits, and an aggregation of a first IP packet and a reference IP packet. Each bit in the bitmap indicates whether a corresponding header information element, of a header of the first IP packet, is redundant or non-redundant with respect to a corresponding header information element of a header of the reference IP packet. Such methods include reconstructing the header of the first IP packet based on the header of the reference IP packet and on the bitmap, and decompressing the header of the first IP packet. Other embodiments include devices configured to perform operations corresponding to such methods, and computer-readable media comprising computer-executable instructions that embody such methods.
