Classification: CPC H | IPC H

Claim 13:
14. A first network function (NF) producer node for use in a 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 a Service Communication Proxy (SCP) node in the communication network, wherein the first NF producer node comprises processing circuitry and a memory, said memory containing instructions executable by said processing circuitry whereby said first NF producer node is operative to:
update a stored service address for a network repository function (NRF) node in the communication network to a service address of the SCP node, wherein the NRF node is storing a NF profile for the first NF producer node;
send a registration request to the SCP node, wherein the registration request is a request to register a NF profile for the first NF producer node at the SCP node; and
prior to sending the registration request:
send a de-registration request to the SCP node, wherein the de-registration request is a request to de-register the first NF producer node from the first NRF node, and wherein the de-registration request comprises an indicator of whether the first NF producer node is to change to a different NRF node; and
receive an acknowledgement of the first de-registration request from the SCP node.
