Sessions in a communication system

摘要

A method in a communications system for handling responses to messages includes a step of sending a message from a first party to a second party. A response to the message is sent, with the response including at least one parameter in breach of a policy for a communication between the first party and the second party. A network controller detects that the response includes at least one parameter breaching the policy. The at least one parameter is modified to be consistent with the policy.
