Abstract
A method, by a first node, for handling provision of an IMS service. A communications network comprises a first slice handling a first IMS service, and a second slice handling a second IMS service. The first node obtains, from a second node at least one of a first and a second indication. The first indication is of a first routing service instance for a third node handling the first service in the first slice. The second indication is of a second routing service instance for a fourth node handling the second service in the second slice. The first node routes a request, to one of the nodes with one of the proviso that when the request is for the first service, the routing is based on the first indication, and when the request is for the second service, the routing is based on the second indication.
