Abstract
When an authorization and/or control element like a policy control network element is involved in the authorization and/or control of a service flow in a communication connection controlled, a network control element, such as a GGSN, controlling the communication connection determines a termination of the thus authorized and/or controlled service flow and informs the policy control network element about the termination thereof. The policy control network element may then remove service attributes and/or QoS attributes related to this service flow. Furthermore, the communication connection in the communication network can be modified on the basis of stored information which represents a state before the establishment of the service flow.
