Dynamic quality of service (QOS) setup over wired and wireless networks

Abstract

A method to setup Quality of Service (QoS) parameters over a wireless network and over a wired network is described herein. A request to setup the QoS parameters may be initiated by a wireless device. The method includes the steps of receiving a first message from the wireless device that includes a first set of QoS parameters requested by the wireless device and determining a second set of QoS parameters for transmission over a wired network corresponding to the first set of QoS parameters. The method further includes the steps of transmitting a second message to a wired device including the second set of QoS parameters and receiving a response to the second message from the wired device that indicates whether the second set of QoS parameters was accepted by the wired device. The method also includes transmitting a response to the first message, based on the response to the second message, to the wireless device indicating whether the first set of QoS parameters are acceptable. A similar method is provided to setup QoS parameters over the wireless network when the initial request is received over the wired network.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 259,911 filed Nov. 10, 2009, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This application generally relates to Quality of Service (QoS) setup and more specifically to dynamic QoS setup over wired and wireless networks.[0004]2. Background Art[0005]Applications running on wireless devices such as cellular phones, wireless enabled laptops, personal digital assistants (PDAs) or any device that communicates over a wireless network have differing Quality of Service (QoS) requirements depending upon the nature of the application. For example, Voice over Internet Protocol (VoIP) applications such as Skype™ require specific parameters such as a controlled latency and jitter for desired operation. Typically, QoS parameters for an application's traffic flows over wireless and wired networks are stat...

AI Technical Summary

Problems solved by technology

If an application such as a VoIP application is initiated in real time and the corresponding traffic flows do not have QoS parameters to support the VoIP call over a wired and / or wireless network, then the call will not function properly.

Current communications systems are not able to dynamically (i.e. in real-time or on-the-fly) create required traffic flows with desired QoS parameters.
