An apparatus and method can include monitoring whether a consumer of a target network receives a resource identifier, a first apiRoot identifying a producer, and a second apiRoot identifying the producer and a producer network. The first apiRoot is for routing a service request to the producer, and the second apiRoot is for routing the service request to the producer if the target network is different from the producer network. The method further comprises identifying the producer network based on the second apiRoot, and deciding whether the target network is different from the producer network. If the target network is not different from the producer network, the service request is sent wherein the resource is identified by the first apiRoot and the identifier. If the target network is different from the producer network, the service request is sent wherein the resource is identified by the second apiRoot and the identifier.

NF service producer's URIs for inter-PLMN mobility

A method, apparatus, and computer program product provide for network communication error originator identification with a header, such as an HTTP header. In the context of a method, the method causes a service request from a NF client to be transmitted to a NF server via one or more intermediary network proxy functions. The method receives a service response with error information identifying the type or identity of the originator of the error response or identifying the type or identity of network proxy function having relayed the error response. The method may also be enabled to redirect a service request to a different NF server or a different network proxy function, and to enable the NF client to determine whether to redirect the request to a different NF server or a different network proxy function.
