METHOD AND NETWORK NODES FOR MANAGING ACTIONS OCCURRING IN A NETWORK SLICE OF A COMMUNICATION NETWORK

A method performed by an IP Multimedia Core Network Subsystem (IMS) node, for enabling management of events occurring in a network slice of a communication network that comprises partitioned sets of functionalities wherein each set of functionalities belongs to a dedicated network slice, and wherein a set of functionalities is separated from other sets of functionalities. The IMS node obtains, from a core network node responsible for policy control, an indication of a first action relating to a session established in the network slice, wherein said first indication comprises a first network slice identifier. The IMS node sends, to a managing node, a message indicating a second action to be performed in the managing node in response to the first action relating to the session established in the network slice, wherein the message comprises a second network slice identifier identifying the first network slice in which the first action occurred.
