Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in dynamically increasing bandwidth for mobile users to support high-data-rate applications like videoconferences, as WWAN bandwidths are often insufficient, and wired aggregation methods do not address mobility or dynamic user needs.
Innovation Solution
The system dynamically aggregates WAN bandwidths of bonded devices using a control network that manages data transmission among community members, allowing devices to share and prioritize bandwidth based on user requirements and device states, forming a Wireless Aggregation for Mobility (WAM) network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If WWAN bandwidth is allocated to individual subscribers, then mobility and secure communication are provided, but bandwidth is insufficient for high-data-rate applications like videoconferences
Solution Approach 1:
The patent combines multiple WWAN connections from different subscribers into a single aggregated bandwidth pool. Bonded devices form a community where individual WWAN connections are merged to provide sufficient bandwidth for high-data-rate applications while maintaining mobility and security benefits of WWAN technology.
Solution Approach 2:
The aggregated bandwidth system provides multiple functions: it maintains individual WWAN connections for mobility and security, combines them for sufficient bandwidth in high-data-rate applications, and dynamically allocates resources based on application needs. This multi-functional approach resolves the contradiction between individual bandwidth limitations and application requirements.
2Adaptability or versatility
If static wired aggregation methods are used, then bandwidth is increased, but mobility and dynamic user needs are not addressed
Solution Approach 1:
The system implements dynamic bandwidth aggregation where bonded devices can join and leave the community dynamically. The bandwidth allocation adjusts in real-time based on which devices are currently bonded and their respective WWAN connection states, enabling mobility support while maintaining sufficient bandwidth for high-data-rate applications.
Solution Approach 2:
The aggregation system operates autonomously by monitoring the bonding states of devices and automatically adjusting bandwidth allocation. The system self-manages the dynamic formation and dissolution of bonded device communities without requiring manual intervention, simplifying operation while providing adaptive bandwidth allocation.
3Productivity
If multiple WWAN connections are aggregated dynamically, then bandwidth is increased for high-data-rate applications, but resource utilization efficiency decreases
Solution Approach 1:
The system implements feedback mechanisms that monitor application bandwidth requirements and current WWAN connection states. Based on this feedback, the system dynamically adjusts which devices are bonded and how bandwidth is allocated, ensuring sufficient resources for high-data-rate applications while avoiding unnecessary aggregation that would waste network resources.
Solution Approach 2:
The system changes aggregation parameters dynamically based on application needs and network conditions. When high-data-rate applications are detected, the system increases aggregation by bonding more devices. When such applications are not active, the system reduces aggregation to improve resource utilization efficiency, thus resolving the contradiction between bandwidth availability and resource efficiency.
