Abstract: There is provided mechanisms for selection of system operational action in a communication system. A method is performed by a system controller. Operation and maintenance data identifying current system conditions in the communication system is obtained. Based on the obtained operation and maintenance data, a set of system operational actions that are candidates to be performed is determined. Each of the system operational actions impacts system operational characteristics of the communication system according to quantitative outcomes with associated probabilities. Each of the system operational actions provides a system operation utility in the communication system. A utility score is determined for each of the system operational actions. The system operational action with highest utility score is selected. Execution of the selected system operational action is initiated in the communication system.

Abstract: The present disclosure relates to a method of validating delegated consent and a node (12) performing the method. In an aspect, a method of validating delegated consent in a chain of nodes (10-14) is provided comprising a first node (10), a plurality of intermediate nodes (11, 13, 14) and a validating node (12), the first node (10) being configured to delegate consent to perform an action on behalf of the first node (10) to a last node (14) of the plurality of intermediate nodes, which delegated consent is validated by the validating node (12) in the chain following the last intermediate node (14) for the delegation of consent to the last intermediate node (14) to be allowed.

Abstract: According to an aspect, there is provided a method of monitoring a quality of service metric for a communications service. The method comprises determining a plurality of performance metrics across a communications network providing the communications service, the performance metrics associated with coordinates of a dimension. Grouping the performance metrics by coordinate using a performance metric data structure (410). Determining the QoS metric for a first coordinate of the dimension using the grouped performance metrics in the performance metric data structure (415). Determining when the QoS metric for the first coordinate does not meet a QoS requirement (420).

Abstract: Disclosed techniques include evaluating Key Performance Indicator (KPI) event information from a production domain (16) to identify nonconformance of a service provided via the production domain with a Service Level Agreement (SLA) governing the service, and outputting actionable nonconformance information. Among the several advantages gained via the disclosed techniques is the use of even low-level KPIs over time to determine higher-level compliance or non-compliance with Service Level Objectives (SLOs) defined by the SLA and the ability to drive Business Support Systems (BSSs) or Service Assurance Systems (SASs) via nonconformance information determined from identified nonconformance with the SLA.

Abstract: The disclosure relates to a method and a billing platform capable of building a real time aggregation without actually generating an invoice. In one embodiment, the method comprises steps of upon occurrence of an event to be charged, calculating (S102) a charge for the event; retrieving (S103) categorization attributes of charge information of the event; generating (S104) an identifier from the categorization attributes; and if an aggregation entity with the identifier does not exist in the billing platform, creating (S106) a new aggregation entity with the charge and the identifier, and storing the new aggregation entity in the billing platform. By storing a real time charge aggregation of an event in the platform rather than the event itself, a real time or continuous view of the upcoming invoice may be provided without actually generating the invoice.
