1. A system comprising:
a 5G Fixed Mobile Interworking Function Database entity (FMIF-DB);
an Access and Mobility Management Function (AMF);
a User Plane Function (UPF);
a Fixed Network Residential Gateway (FN-RG);
a Wireline 5G Access Network (W-5GAN); and
a provisioning service entity,
wherein the W-5GAN is connected to the FN-RG,
wherein the W-5GAN comprises a Wireline Access Node (AN) and a 5G Fixed Mobile Interworking Function (FMIF),
wherein the FMIF is connected to the AMF and to the UPF and to the FMIF-DB,
wherein the AN is coupled to the FN-RG,
wherein the provisioning service entity is configured to perform operations comprising:
receiving a create user message from a network operator;
creating a subscription for a FN-RG identity in the provisioning service entity; and
issuing a request to the FMIF-DB to setup and store a User Entity (UE) credential and configuration data for the FN-RG, and
wherein the FMIF-DB is configured to perform operations comprising:
storing the received UE credentials for providing an identity of the FN-RG as a UE;
storing the UE configuration data for the FN-RG;
receiving a circuit identity (ID) request message from the FMIF in response to the FMIF receiving a circuit ID discovery message from the AN; and
responding to the FMIF with the circuit ID.
