SaMOG Bearer Management via QoS Parameter Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing bearers when user equipment accesses wireless carrier networks through wireless local area networks (WLANs, especially in ensuring quality of service (QoS) parameters are enforced for packet transmission, leading to potential service quality issues and network congestion.
Innovation Solution
The method involves selecting traffic management parameters based on QoS parameters associated with the wireless carrier network, which are then enforced by user equipment and access points for packet transmission over WLANs, utilizing techniques like Enhanced Distributed Channel Access (EDCA) to prioritize and filter packets accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traffic management parameters are not enforced in WLAN, then device complexity and implementation ease are improved, but service quality and QoS parameter enforcement deteriorate
Solution Approach 1:
The patent introduces an intermediary mechanism that maps QoS parameters from the wireless carrier network to traffic management parameters in the WLAN. This intermediary layer translates between different parameter systems, allowing QoS enforcement without requiring complex native WLAN QoS implementation. The mapping function acts as a bridge that preserves service quality while maintaining implementation simplicity.
Solution Approach 2:
The patent transforms QoS parameters into equivalent traffic management parameters through systematic parameter mapping. By changing the parameter representation from network-level QoS descriptors to WLAN-level traffic management descriptors, the system enforces quality requirements without requiring the WLAN infrastructure to natively understand carrier network QoS parameters.
2Reliability
If QoS parameters are enforced through WLAN, then service quality is improved, but device complexity increases
Solution Approach 1:
The mapping mechanism serves as a complexity-reducing intermediary that handles the translation between QoS and traffic management parameters. Rather than requiring complex native WLAN QoS enforcement, the system uses this intermediary layer to manage the complexity, allowing simple WLAN infrastructure to support complex QoS requirements through parameter translation.
Solution Approach 2:
The traffic management parameter mapping mechanism provides universal functionality that works across different WLAN configurations and carrier network types. By creating a standardized mapping approach, the system handles diverse QoS requirements through a single multi-functional mechanism, reducing overall system complexity while maintaining broad service quality support.
3Productivity
If traffic is managed without parameter selection, then network congestion occurs, but implementing parameter selection increases processing overhead
Solution Approach 1:
The patent performs traffic management parameter selection in advance, during the bearer setup phase, before actual data transmission begins. By pre-selecting and configuring the appropriate traffic management parameters based on QoS requirements, the system avoids real-time processing delays during data transmission, thus improving network efficiency without significant processing overhead.
Solution Approach 2:
The system transforms QoS parameters into traffic management parameters through efficient parameter mapping and selection. This parameter transformation occurs during bearer establishment, allowing the system to optimize traffic flow characteristics in advance without requiring complex real-time parameter adjustments during active data transmission.

AI summary
Systems, methods, and devices for accessing a service of a wireless carrier network through a wireless local area network (WLAN) are described. A method includes selecting one or more traffic management parameters associated with the WLAN based at least in part on one or more quality of service (QoS) parameters associated with the service of the wireless carrier network being accessed. The method further includes transmitting packets over the WLAN using the selected one or more traffic management parameters associated with the WLAN when a user equipment accesses the service of the wireless carrier network through the WLAN. The user equipment enforces the selected one or more traffic management parameters for communications to the wireless carrier network. An access point enforces the selected one or more traffic management parameters for communications to the user equipment.
