Embodiment Construction

[0027] The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art scope of the invention. In the drawings, like reference numerals indicate like elements.

[0028] All prior art methods of QoS control discussed above involve controlling the use of transmission resources. The use of transport resources can be controlled, for example, by reserving bandwidth and forwarding resources. These prior art methods may be able to achieve sufficient QoS control where the availability of transport resources is the QoS limiting factor. However, this is not always the case. In some cases, despite the exist...

Abstract

Embodiments of the present invention relate to network nodes and methods that allow for improved QoS control in a telecommunications network by providing combined reservation of transport resources and processing resources for a traffic flow. The amount of transport resources and the amount of processing resources required in connection with a traffic flow can be signaled in a signaling message from a sender node to a receiver node to enable reservation of appropriate amounts of processing resources as well as transport resources.

Description

technical field [0001] The present invention relates to methods and arrangements for dynamic resource reservation in telecommunication networks. Background technique [0002] Resource reservation methods in IP / Ethernet transport networks are becoming more and more important because carrier-grade transport networks require methods for guaranteed service, ie methods that provide some guaranteed Quality of Service (QoS) of service. IP (Internet Protocol) transport is currently being introduced into mobile access networks such as WCDMA RAN (Wideband Code Division Multiple Access Radio Access Network) and LTE (Long Term Evolution) networks. In this type of access network, users and signaling services often share limited transmission resources. Therefore, resource reservation of these transport resources is required. In order to provide dynamic resource reservation, a signaling protocol is used. [0003] There are several different methods for QoS control, such as IntServ (Inte...
