scope:

The present document is an Integration Reference Point (IRP) named "Evolved Packet Core (EPC) and non-3GPP access interworking system Network resource Model (NRM) IRP; Information Service (IS)", through which an 'IRPAgent' (typically an Element Manager or Network Element) can communicate configuration management information to one or several 'IRPManagers' (typically Network Managers) concerning interworking network resources.

The present document specifies the semantics and behaviour of Information Object Class (IOC) attributes and relations visible across the reference point in a protocol and technology neutral way. It does not define their syntax and encoding.

It reuses relevant parts of the generic NRM in 3GPP TS 28.622 [6], either by direct reuse or sub-classing, and in addition to that defines specific IOCs in EPC and non-3GPP access interworking systems.

In order to access the information defined by this NRM, an interface IRP is needed, such as the Basic CM IRP IS (3GPP TS 32.602 [7]) or the Bulk CM IRP IS (3GPP TS 32.612 [8]). However, which interface IRP is applicable is outside the scope of the present document.
