Classification: CPC H | IPC H

Claim 1:
2. A Service Communication Proxy (SCP) node for use in a communication network as a proxy network repository function (NRF) for a first network function (NF) producer node in the communication network, wherein the first NF producer node is to migrate from a direct communication mode with a first NF consumer node to an indirect communication mode with the first NF consumer node via the SCP, wherein the SCP node comprises processing circuitry and a memory, said memory containing instructions executable by said processing circuitry, whereby said SCP node is operative to:
receive a registration request from the first NF producer node, wherein the registration request is a request to register a NF profile for the first NF producer node at the SCP node, wherein the NF profile indicates a service address for the first NF producer node;
in response to the received registration request, determine that the NF profile for the first NF producer node is currently registered with a first NRF node in the communication network;
in response to the determination, send an update request to the first NRF node to update the NF profile currently registered for the first NF producer node stored by the first NRF node, to replace the service address of the first NF producer node stored by the first NRF node with a first service address of the SCP node; and
prior to the determination, send an authorisation request to the first NRF node to request authorisation to access service information of NF producer nodes stored by the first NRF node.
