Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for frequency band reselection in wireless networks are inefficient, particularly when wireless devices transition from idle mode, often selecting unsuitable bands due to static priority settings, which can lead to suboptimal uplink traffic handling.
Innovation Solution
A system and method that determine and transmit reselection priorities for communication bands based on their suitability for uplink traffic, considering properties like frame configuration and bandwidth, allowing wireless devices to dynamically select more suitable bands for improved service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static priority settings are used for frequency band reselection, then device complexity is reduced and ease of operation is improved, but communication quality and uplink traffic handling deteriorate
Solution Approach 1:
The patent implements dynamic priority settings for frequency band reselection. The network node determines reselection priorities based on current network conditions, frame configurations, and bandwidth availability, then transmits these dynamic priorities to the wireless device. This allows the system to adapt to changing traffic conditions while maintaining automated operation, resolving the contradiction between ease of use and communication quality.
Solution Approach 2:
The patent changes the priority parameter from static to dynamic based on frame configuration and bandwidth characteristics. By evaluating multiple parameters (frame configuration, bandwidth, traffic conditions) and adjusting reselection priorities accordingly, the system improves communication quality without requiring complex user intervention, as the network node automatically manages the parameter adjustments.
2Reliability
If dynamic reselection priorities based on frame configuration and bandwidth are implemented, then communication quality and uplink traffic handling are improved, but device complexity and network processing requirements increase
Solution Approach 1:
The patent introduces a network node as an intermediary that performs the complex determination of reselection priorities. Instead of requiring the wireless device to independently analyze frame configurations and bandwidth parameters, the network node acts as a mediator that evaluates these parameters and transmits the determined priorities to the device. This reduces device complexity while maintaining improved uplink traffic handling through dynamic priorities.
Solution Approach 2:
The network node performs preliminary determination of reselection priorities based on frame configuration and bandwidth before the wireless device needs to make reselection decisions. By pre-calculating and transmitting these priorities, the system avoids requiring complex real-time analysis at the device level, thus reducing device complexity while ensuring optimal priorities are available when needed for uplink traffic handling.
3Productivity
If wireless devices select frequency bands using current static methods, then device complexity is minimized, but network performance and service quality deteriorate due to inefficient band selection
Solution Approach 1:
The network node serves as an intermediary that determines and transmits reselection priorities to wireless devices. This mediator approach enables improved network performance through optimized band selection based on frame configuration and bandwidth, while the actual complex determination logic resides in the network infrastructure rather than in each device, thus not increasing device complexity.
4Adaptability or versatility
If reselection priority is transmitted to wireless devices for dynamic band selection, then adaptability to traffic conditions is improved, but loss of information increases due to additional signaling
Solution Approach 1:
The patent extracts only the essential reselection priority information from the complex set of network parameters and transmits only this extracted essential information to wireless devices. By taking out only the necessary priority values rather than transmitting all underlying parameters (frame configurations, bandwidth details, traffic conditions), the system achieves adaptability in band reselection while minimizing signaling overhead and information loss.
