Abstract: A method in a network node is provided for mitigating disruption during maintenance of an edge gateway node of a communication network. The edge gateway node connects devices to services(s) of the communication network. First device(s) are capable of connecting to a cloud environment in the absence of the edge gateway node, and second device(s) are incapable of connecting to the cloud environment in the absence of the edge gateway node. The method comprises: establishing respective virtual devices for the second device(s), the virtual devices comprising predictive models trained to replicate data output by the respective second device(s); and, during a time interval in which the maintenance of the edge gateway node is performed: configuring the virtual device(s) to connect to a virtual edge gateway node established in the cloud environment; and configuring at least one of the first device(s) to connect to the virtual edge gateway node.

Abstract: An artificial intelligence, AI, planning controller control the timing of when a plan (16) to accomplish a task (14) is synthesized. The AI planning controller in this regard determines a quiescent phase (20) during which values of at least some predicates describing a state of the system (12) will remain stable. The AI planning controller then controls artificial intelligence planning to synthesize the plan (16) during at least some of the quiescent phase (20).

Abstract: A method implemented by a network device to predict smart contract violations, where the network device is communicatively coupled to one or more computing nodes that execute one or more smart contracts that are configured to perform transactions on a blockchain. The method includes generating a control flow graph for each of the one or more smart contracts, retrieving, from the blockchain, a current state of a variable utilized by the one or more smart contracts following execution of a transaction that updates the variable, generating or updating a state space tree based on the current state of the variable and the control flow graphs generated for the one or more smart contracts, determining whether the state space tree meets a predefined violation requirement, and sending an alert to the one or more computing nodes in response to determining that the state space tree meets the violation requirement.

Abstract: It is provided a method for providing device data from a source device to a data requester. The method is performed in a data provider and comprises the steps of: determining operating mode being either a pass-through mode or a cache mode, based on estimated resource usage for each of the pass-through mode and the cache mode; receiving a read request from the data requester; when the data provider is in the pass-through mode, transmitting a corresponding read request to the source device and forwarding a read response from the source device to the data requester; when the data provider is in the cache mode, retrieving device data from storage of the data provider and transmitting a read response to the data requester, the read response comprising the device data from storage; and populating the storage of the data provider with device data received from the source device.

Abstract: A method and a system are presented for enabling coordinated executions of actions in a distributed computing system with untrusted local computing agents. A smart contract including plans is recorded in a blockchain database. Each plan includes actions to be executed by a respective one of the local computing agents. Execution of a first action of a first set of actions to be executed by a first local computing agent is requested. Execution of a second action of a second set of actions to be executed by a second local computing agent is requested. Responsive to determining, based on the smart contract, that the first action can be executed, the first local computing agent is caused to execute the first action and responsive to determining, based on the smart contract, that the second action cannot be executed, the second local computing agent is caused to not execute the second action.

Abstract: A method for managing an air quality control system is disclosed. The method includes monitoring air quality changes in an environment caused by a deployment of units, estimating individual rates of change of air quality achieved by specific units, and using the estimated rates of change to train a prediction model. The method further includes receiving a request for air quality control of a specified environment, using the trained prediction model to predict unit rates of change that would be achieved by units if deployed within the specified environment and generating an assignment of units for the specified environment on the basis of the predicted unit rates of change and a target air quality parameter.

Abstract: In a M2M device management system, a Task Orchestration Module, TOM (32) external to the M2M device (20) manages the execution of tasks wholly or partly on the M2M device (20). This alleviates the M2M device (20) of the need to store code, execute tasks, monitor task execution, and the like. The tasks are specified using Finite State Machine, FSM, syntax. A task URL, tURL (34) resource on the M2M device (20) provides a tURL (34) to a resource hosting (36) a service (38) mapping task-IDs to FSM specifications. Communications between the TOM (32) and M2M device (20) is compactly and efficiently achieved using a device management protocol server/client system (16, 18), such as LightWeightM2M (LWM2M). A predetermined mapping (40) at the M2M device (20) maps action labels to library functions (22) of the M2M device (20), obviating the need for code in the M2M device (20) to interpret and execute actions.

Abstract: A method and a location service component for providing an estimate of a location related to a device are disclosed. The location service component receives a request from a client for the estimate of the location and estimates the location based on a predictive model to obtain an initial set of data items. Each data item includes a respective estimate of the location and a set of identities representing one or more further devices in a neighborhood of the device. The location service component obtains a respective location for each of the further devices based on the set of identities. The location service component removes data items that are inconsistent with the respective location for the further devices to obtain a pruned set of data items. The location service component sends, estimates of the pruned set of data items to the client. A corresponding computer program and a computer program carrier are also disclosed.

Abstract: Provided is a method for managing a network slice instance (NSI) in a communications network. A first performance of the NSI is monitored by a first network slice subnet instance (NSSI) associated with the NSI. A first node obtains, from a second node, a request to monitor a second performance of the NSI. The second performance is of one or more microservices to provide data on a sector of the network. The first node determines, based on one or more requirements of the request, to perform one of: i) initiating (303) a creation of a second NSSI adapted to monitor the second performance based on the requirements, and ii) modifying, based on the requirements, an existing second NSSI, to monitor the second performance. The created or modified second NSSI being: a) independent from, and b) sharable with, the first subnet slice instance.
