Accessing network-internal functions of telecommunications networks externally involves interface checking for request to use function of another network in external request for internal function

摘要

The method involves an interface checking if a request from an external point for an internal function contains a request for a function of another network and if so exchanging a second request re the function of the target network between the interfaces based on a service agreement between the interface device and a secure service interface device of the target network. The method involves accessing network-internal functions of telecommunications networks from an external point (SE) via a secured service interface (S2) of a network (N2) based on a valid service agreement in favor of the external point. The interface checks whether a request from the external point re an internal function contains a request to use a function of another network (N1) and if so exchanges a second request re the function of the target network between the interfaces based on a service agreement between the interface device and a secure service interface device (S1) of the target network. An Independent claim is also included for the following: (a) a network device of a telecommunications network for implementing the inventive method.
