FIRST SERVICE COMMUNICATION PROXY NODE, SECOND COMMUNICATION PROXY NODE AND METHODS IN A WIRELESS COMMUNICATION NETWORK

A method performed by a second SCP node for handling control plane traffic of a service related to a UE is provided. At a relocation of the control plane traffic of the service from a first AMF passing a first SCP node towards a second AMF, the second SCP receives, from the first SCP node, a UE context including a URI of the original resource in a NF. The second SCP then changes the URI of the original resource in the NF to a second URI, in the UE context, which second URI is related to a NF service association. The second SCP node then sends, to the second AMF, the UE context including the second URI, enabling the control plane traffic of the service from the second AMF to pass the second SCP for control plane traffic related to the resource in the NF.
