Patent ID: 11929882

Abstract:
There is provided a method of operating a Service Communication Proxy, SCP, node (608, 1000) in a communication network as a proxy network repository function, NRF, for a first network function, NF, producer node in the communication network. The first NF producer node (602, 1100) is to migrate from a direct communication mode with a first NF consumer node (606) to an indirect communication mode with the first NF consumer node (606) via the SCP node (608, 1000). The SCP node (608, 1000) discovers a NF profile for the first NF producer node (602, 1100), wherein the NF profile for the first NF producer node (602, 1100) is stored by a first network repository function, NRF, node (604) in the communication network, and the NF profile comprises a service address for the first NF producer node (602, 1100); receives a registration request from the first NF producer node (602, 1100), wherein the registration request is a request to register a NF profile for the first NF producer node (602, 1100) at a NRF node (604), wherein the registration request indicates the service address for the first NF producer node (602, 1100); and, in response to the received registration request, sends an update request to the first NRF node (604) to update the NF profile for the first NF producer node (602, 1100) stored by the first NRF node (604) to replace the service address of the first NF producer node (602, 1100) with a first service address of the SCP node (608, 1000) that is associated with the service address of the first NF producer node (602, 1100).
