Abstract
Embodiments herein relate to a method performed by a first network node (150) in a wireless communications network (100), for handling an addition of a participant to an ongoing call session for a first UE (120) handled by an IMS node (140). The ongoing call session is a session between the first UE (120) and a second UE (121). The first network node receives, from a second network node (151), a request to add a participant to an ongoing call session for the first UE (120). The first network node (150) obtains a list of one or more ongoing call sessions for the first user from the IMS node (140), wherein the list comprises an identifier for identifying each of the one or more ongoing call sessions. The first network node 150 further sends, to the IMS node (140), a request to add the participant to one of the one or more ongoing call sessions for the first UE (120), wherein the request comprises the identifier for identifying the call session to which the participant is to be added and an identification of the participant to add to the ongoing call session. Embodiments herein further relate to methods performed by the second network node (151) and the IMS node (140).
