Abstract: Provided are an architecture, method and apparatus for realizing communication between network functions. The network function establishes interworking with other communication domains via the interface function. An interworking interface between a network function and a selected interface function is identical to an interworking interface between the network function and a destination network function. With the architecture, the network function and the interface function are decoupled. The interworking between network functions within the communication domain and the interworking between the network function within the communication domain and the network function outside the communication domain are achieved by using only one type of interworking interface.

Abstract: Provided are an architecture, method and apparatus for realizing communication between network functions. An interworking interface between the network function and a selected interface function which is in the same communication domain with the network function is identical to an interworking interface between the network function and a destination network function which is in the same communication domain with the network function. With the architecture, the network function and the interface function are decoupled. The network function can realize the interworking with the network function inside the communication domain as well as the interworking with a destination network function outside the communication domain by only one type of interworking interface, so that the logic of the network functions becomes simple, thereby simplifying the design of the network functions and greatly reducing the development and deployment difficulties of the network functions.
