Uplink Traffic Classification for Wireless QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack effective techniques for classifying uplink and bi-directional traffic streams, which hinders the achievement of desired quality of service (QoS) for various data types, such as voice and video, leading to inconsistent performance.
Innovation Solution
Implementing traffic classification techniques at both stations and access points using classification parameters like source and destination addresses, and QoS parameters to identify and manage packets for uplink and bi-directional traffic streams, ensuring they are transmitted according to negotiated service specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic classification techniques are implemented at stations and access points, then quality of service for uplink and bi-directional traffic streams is improved, but device complexity increases
Solution Approach 1:
The patent segments traffic into different streams (uplink, downlink, bi-directional) and applies classification techniques selectively to each type. This allows QoS to be improved for specific traffic types without unnecessarily complicating the handling of all traffic, thereby resolving the contradiction between reliability improvement and device complexity increase.
2Reliability
If granular control over traffic streams is implemented, then quality of service for multimedia applications is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different QoS parameters and classification rules to different traffic streams based on their specific requirements. For example, voice traffic receives different treatment than data traffic. This local quality approach enhances QoS for multimedia applications without requiring uniform high precision across all system components, thereby resolving the contradiction.

AI summary
Techniques for performing traffic classification for uplink and bi-directional traffic streams are described. A station receives packets for transmission on the uplink to an access point. The station identifies packets for each uplink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The station sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream. The access point receives packets for transmission on the downlink to at least one station. The access point identifies packets for each downlink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The access point sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream.
