wherein—in order to enable or to provide communication services to the subscriber devices requesting such communication services—AAA-related messages are sent and received by both the authentication server entity and a service edge entity via an access orchestrator entity as part of the access network, the AAA-related messages conforming to or using an access protocol used between the authentication server entity and the service edge entity,
wherein the method comprises:
in a first step, a first AAA-related message is sent by the authentication server entity and received by the access orchestrator entity, the first AAA-related message comprising:
at least one standardized message attribute according to the access protocol;
and
at least one vendor-specific message attribute;
in a second step, subsequent to the first step, the access orchestrator entity sends a second AAA-related message to the service edge entity, the second AAA-related message solely comprising the at least one standardized message attribute according to the access protocol; and
in a third step, subsequent to the first step and prior to, during or after the second step, the access orchestrator entity sends at least one third AAA-related message to the service edge entity, the at least one third AAA-related message corresponding to a message according to an application programming interface (API) or to a further access protocol.
