Abstract

A method and system forwards a service-related information to network user, wherein at least one new event package directed to a service configuration and/or a de-registration state of the network user is provided at a session control device or a default server or an application server, respectively. A terminal device of the network user initiates a subscription to the new event package. In response thereto, a notification informing about the service configuration and/or the de-registration state of the network user is generated and routed to the terminal device to be made available to the network user.
