Abstract

Embodiments herein relate to a method performed by an IMS node for handling data of a UE, in a communication network, wherein the communication network comprises partitioned sets of functionalities of one or more core networks wherein each set of functionalities belongs to a network slice. The IMS node receives, from the UE, a message for registering the UE to the IMS node, wherein the message comprises a slice indication indicating a network slice identity and a UE indication identifying the UE. The IMS node stores a registration of the UE in the IMS node, in addition to a previously stored registration of the UE, with the proviso that the indicated network slice identity differs from a previous network slice identity of the previously stored registration of the UE and thereby allowing parallel active communications using the registration and the previously stored registration.
