Patent ID: 7817554

Claim:
A method in a network node in a mobile communication network for changing quality of service parameters during an ongoing communication session wherein at least one client terminal utilizes services provided via the network node, and wherein initial quality of service parameters are used in the ongoing communication session, the method comprises the steps of: determining, upon a content request issued by the at least one client terminal, second quality of service parameters associated to a response to said request; comparing the initial quality of service parameters with the second quality of service parameters to determine a requirement for modifying quality of service parameters; and modifying, if a requirement of modification is identified in the comparing/determining steps, quality of service parameters by issuing to the client terminal, an update from the initial quality of service parameters to the second quality of service parameters, and thereby facilitating a delivery of a response to the content request with the use of the second quality of service parameters, wherein the steps of comparing quality of service parameters comprises a substep of retrieving PDP information on the initial quality of service parameters from a session database, the PDP information being associated with the communication session.
