Methods and devices for changing quality of service
First Claim
1. 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.

Abstract
Quality of Service parameters are changed to adapt a transmission to varying transmission capacity demands. During an ongoing communication session, at least one client terminal utilizes services provided via a network node, and initial quality of service parameters are used. In the process of responding to a content request originating from the client terminal, it is determined if a delivery of the response to the content request would benefit from a modification of quality of service parameters. If the modification is determined to be beneficiary, a modification 520 of quality of service parameters for use in the response to the content request is initiated.

25. A network node in a mobile communication network adapted to provide access to services from a service provider in a communication session, wherein a client terminal utilizes services provided via the network node and initial quality of service parameters are used, the network node comprising:
-
a quality of service determining processor arranged to, on an content request issued by the client terminal, determine second quality of service parameters associated to the requested content; a comparator arranged to compare the initial quality of service parameters with the second quality of service parameters; and a quality of service modification processor arranged to issue an update from the initial quality of service parameters to the second quality of service parameters using an update PDP context message to facilitate a delivery of a response to the content request with the use of the second quality of service parameters, wherein the comparator is arranged to retrieve PDP information on the initial quality of service parameters from a session database, the PDP information being associated with the communication session. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
