Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network connection management solutions are not optimized for Multi-Device Experience (MDE) scenarios, leading to performance degradation and slow user experiences due to improper network connection, data traffic imbalance, and incorrect priority assignment, especially when handling high-bandwidth and low-latency applications.
Innovation Solution
A method and device that prioritize connecting multiple devices to the same wireless communication network by calculating weighted network scores, balancing data traffic, and assigning priority levels to ensure seamless MDE performance, using techniques such as dual-band Wi-Fi management and priority mapping based on TCP/IP ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing network connection management solutions are used, then general network connectivity is maintained, but MDE specific performance degrades due to lack of optimization for high-bandwidth and low-latency applications
Solution Approach 1:
The patent implements MDE-specific network management by creating dedicated network groups and applying specific policies to MDE traffic flows. Different network configurations and priority levels are assigned based on the specific MDE application requirements, rather than applying uniform network management to all traffic.
Solution Approach 2:
The system dynamically determines network availability and selects optimal networks based on current conditions. Network scores are calculated and updated, and the system can switch between different networks (Wi-Fi, cellular, Ethernet) based on real-time performance requirements of MDE applications.
2Reliability
If devices connect to different networks, then individual device connectivity is maximized, but seamless MDE interaction deteriorates due to network inconsistency
Solution Approach 1:
The patent merges network selection decisions across multiple devices by introducing a network scorer that evaluates networks from the perspective of the MDE application pair. Both devices are instructed to connect to the same network based on combined network scores, ensuring network consistency for seamless interaction.
Solution Approach 2:
The system implements feedback mechanisms where network performance is continuously monitored and scored. Based on these scores, the system provides instructions to devices to switch networks if needed, creating a closed-loop control system that maintains optimal network connectivity for MDE applications.
3Ease of operation
If data traffic is not prioritized, then network load balancing is simplified, but user experience deteriorates due to incorrect priority assignment in multi-application scenarios
Solution Approach 1:
The patent segments data traffic into different flows based on MDE application requirements. Network priority groups and traffic flow specifications divide the network traffic into manageable segments, allowing differential priority handling without requiring complete redesign of the traffic management system.
Solution Approach 2:
The system changes traffic parameters dynamically by assigning different priority levels and network group assignments based on the specific MDE application. TCP/IP port-based priority mapping and DSCP marker settings modify traffic characteristics to enable quality-of-service differentiation.
