Abstract: A method and a scoring node for estimating a user's Quality of Experience, QoE, when a service is delivered in a media stream to the user by means of a communication network. Quality-related parameters pertaining to the service delivery are extracted, and an individual opinion score is determined for each of a set of quality models by applying each respective quality model in the set on the quality-related parameters. An aggregated opinion score is then determined as a weighted average of the individual opinion scores. The aggregated opinion score can then be used as an estimation of the user's QoE for the service delivery, e.g. when evaluating the service and/or the communication network.

Abstract: Methods and devices for maintaining a device-operated function. A first device initially operates as an active master with responsibility to execute the device-operated function by automatically performing one or more operation tasks according to certain operational parameters and gaining knowledge when performing the operation tasks. Meanwhile, a second device is acting as a passive standby device. When the first device cannot or should not operate as the active master anymore, e.g. due to low battery, the responsibility is transferred to the second device by transferring the operational parameters and the knowledge from the first device to the second device. Then, the second device operates as the active master with responsibility to execute the device-operated function according to the operational parameters and using the knowledge if required.

The migration managing module determines a point in time relating to completion of the migration of the service based on resource requirements related to the service. For each radio network node a respective impact on a quality of the service is estimated. Moreover, the migration managing module selects from among servers at least one respective target server for which the respective server location measure of said at least one respective target server matches the respective radio network node location measure of said each radio network node, thereby obtaining a set of target servers comprising said at least one respective target server for said each radio network node. For each target server, a respective cost of the migration based on the resource requirements related to the service is determined. A respective tendency as a function of said each probability value, the respective cost and the respective impact is determined.
