Patent ID: 11825332

Abstract:
A method of operation of an OAM node in a 5G system for fulfilling a service level agreement (SLA) for a network slice. The method comprises the OAM node initializing the slice information at a first network entity (NSSF) including the initial number of users allowed for a slice and transmitting information related to KPI for the slice for QoE monitoring; receiving one or more Quality of Experience (QoE) measurements related to one or more users of the slice, using the received one or more QoE measurements to determine whether the KPI for the slice is reached in accordance with the SLA and in response to determining that the KPI for the slice is not in accordance with the SLA, triggering an action in at least one of corresponding Radio Access Network or a Core Network associated with the slice, such as resource reconfiguration or redistribution across different slices.
