Indication of service flow termination by network control to policy decision function
First Claim
1. A method, comprising:
- determining, in a core network gateway element controlling a communication connection, a termination of at least one existing service flow of an established communication connection, wherein the at least one existing service flow of the established communication connection is a service flow authorized by a policy control element;
informing, by the core network gateway element, the policy control element about the termination of the at least one existing service flow; and
receiving from a processor, in the policy control element, the information about the termination of the at least one existing service flow, the information indicating communication connection parameters being equivalent to communication connection parameters before the establishment of the at least one existing service flow for continuing the established communication connection without the at least one existing service flow being terminated.

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.
