Internet protocol multimedia subsystem (IMS) nodes, core network node, and methods therein, in a communications network

A method performed by a first Internet protocol Multimedia System (IMS) node for handling a subscription of exposure of an IMS call related monitoring event in a communications network is provided. The first IMS node receives (601) via a second Service Based Interface (SBI), from a Core Network (CN) node, a request for a subscription to expose the IMS call related monitoring event for a User Equipment (UE) in an IMS network. The request indicates a first ID identifying a type of the call related monitoring event, a second ID identifying the network node, from which the request is originating, a third ID identifying the UE, and a fourth ID identifying the CN node. When the UE has been registered in the first IMS node for an IMS identity, the first IMS node receives (602) from a second IMS node via a fourth SBI, a fifth ID identifying the second IMS node selected to serve the UE in the IMS network. Based on the fifth ID, the first IMS node sends (603) the subscription request to the second IMS node via a third SBI, instructing the second IMS node to setup the requested subscription. The subscription when setup, enables the second IMS node to, when a call related event is detected that is related to the setup subscription, report the call related event according to any one out of: —by direct reporting via a third SBI to the CN node or —by indirect reporting to the CN node using the second SBI, via the first IMS, node, using the fourth SBI.
