A method performed by a vehicle manager () for managing a remote-controlled vehicle (). The vehicle manager () obtains an original route to the destination passing a sequence of radio access points in a wireless network that a wireless device in the vehicle () will connect to in a communication with the vehicle manager () when the vehicle () travels along the original route. The vehicle manager () detects at least one deficient radio access point of the original route. The vehicle manager () then instructs the vehicle () to adapt its behaviour based on said detecting.

In a communication system, a first network node is configured to execute at least one service application executing a first service and at least one analytics application executing at least part of a distributed analytics service. The first network node obtains information about a new telecommunication service and transmits, to a second network node in the communication system, a request for a policy for the new telecommunication service. The first network node receives, from the second network node, the policy for the new telecommunication service and updates a currently applied policy on the basis of the received policy. The updated policy rebalances resources allocated from a shared computing resource pool of the first network node between the new telecommunication service and the at least one analytics application such that the new telecommunication service maintains adherence to the one or more requirements of a service level agreement.

A method and a network agent for providing cell assignment for a wireless device served by a network node. An input vector is created for a set of candidate cells based on measurements by the wireless device and/or by the network node related to performance and signals. A future effect of assigning the wireless device to a candidate cell is estimated for each candidate cell by applying the created input vector to an effect estimation function which may be a Q-learning function. A cell in the set of candidate cells is then determined and assigned for the wireless device, based on the estimated future effects of the candidate cells. The cell that provides the best future effect may be selected for cell assignment.

The network node is adapted to execute at least one service application () executing a first service and at least one analytics application () executing at least part of a distributed analytics service, where the network node further is adapted to comprise a node policy agent () and a node manager (). By applying a policy restrictions on the analytics task executed on the same network node as a service application, service level agreements for the service application in a telecommunication cloud can be upheld.

A method for predicting a location of a fault in a system is described. The method includes obtaining a faulty unit pertaining to a Supervised Self-Organizing Map (SSOM), wherein the faulty unit has been derived from a sample of machine-level metrics for the system and the SSOM has been trained with a first layer of machine-level metrics and a second layer of service-level metrics. The method further includes expanding a circle originating at the faulty unit until a number of normal units of the SSOM falls within the circle, computing, for each machine-level metric, a score based on differences between the faulty and normal units, wherein a set of scores comprises the respective score for each machine-level metric, and selecting a sub-set of the set, wherein the sub-set comprises the greatest scores of the set, whereby the fault is predicted as located according to metrics represented by the sub-set.

A method and network device for resource-aware dynamic monitoring of application units is described. Instantiation of a monitoring element is caused. A first usage status of resources is obtained. Configuration parameters of the monitoring element are set based upon the first usage status of the resources. The monitoring element is scheduled based upon the first usage status of the resources. A second usage status of the resources is obtained. A determination is performed of whether to update the monitoring element based upon the second usage status of the resources. Responsive to determining that the monitoring element is to be updated, at least one of the following is performed: (i) updating the one or more configuration parameters of the monitoring element based upon the second usage status of the resources, and (ii) rescheduling the monitoring element based upon the second usage status of the resources.

Dynamic management of monitoring tasks in a cloud environment

A first network device enables active measurement in a network path between a second network device acting as a controller of a network performance observability protocol and a wireless device. The first network device captures a measurement packet from the second network device; determines a destination of the measurement packet; and determines a measurement model associated with the destination. The measurement model represents a correspondence between one or more parameters related to the wireless device and estimated values of a measurement for the wireless device. The first network device determines a current value of a parameter related to the wireless device; determines, based on the current value of the parameter and the measurement model, a current estimation of the measurement for the wireless device; and responds to the measurement packet based on the current estimation of the measurement while avoiding to transmit the measurement packet to the wireless device.

Mechanisms for designating particular nodes in a network as measurement endpoint (MEP) nodes are disclosed. Network topology information that identifies a plurality of nodes and communication links in a network is accessed. An initial chromosome generation is established. Each chromosome in the chromosome generation comprises a structure that identifies each node in the plurality of nodes that has an MEP capability and that includes an MEP state indicator for each node. A succession of a plurality of chromosome generations are generated by evolving each chromosome generation into a successive chromosome generation based on a genetic selection function and a fitness function until a threshold condition is met. An optimal chromosome from a successive chromosome generation is determined. A configuration command is sent to each node in a subset of the nodes that configures each node to operate as a MEP node.
