Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Multiple Access Management Services (MAMS) frameworks face challenges in dynamically selecting and combining network paths across multiple access technologies without impacting control plane signaling, leading to inefficiencies in network resource utilization and user experience.
Innovation Solution
The implementation of a programmable framework that leverages network intelligence and policies to dynamically adapt traffic distribution and user plane treatments across selected paths, using a Generic Multi-Access (GMA) protocol to enable flexible selection and combination of access and core network paths, and supports advanced features like lossless switching and traffic splitting without altering existing network protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic keep-alive messages are sent to maintain network paths, then path reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic keep-alive messages sent at configurable intervals to maintain network paths. The periodic action is controlled by a timer that triggers keep-alive transmissions only when necessary, balancing path maintenance with energy conservation. This resolves the contradiction by making the periodic action adaptive rather than continuous.
Solution Approach 2:
The keep-alive mechanism dynamically adjusts its behavior based on network conditions and path state. The system transitions from static periodic transmission to dynamic on-demand transmission, where keep-alive messages are sent only when the path may be compromised or during specific network events, thereby reducing unnecessary energy consumption while maintaining reliability.
2Productivity
If multiple network paths are dynamically selected and combined, then network efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the network path management function into separate components: path selection logic, path maintenance (keep-alive), and traffic routing. This segmentation allows each component to be optimized independently and simplifies the overall device architecture by dividing the complex task of multi-path management into manageable modules.
Solution Approach 2:
The patent introduces a mediator component that handles the complexity of path selection and maintenance, shielding the simpler traffic routing logic from the complexity. This intermediary layer manages the multi-path dynamics while presenting a simplified interface to both the selection algorithms and the routing mechanisms.
3Use of energy by moving object
If trigger-based keep-alive mechanism is implemented, then energy consumption is reduced, but path reliability may deteriorate
Solution Approach 1:
The trigger-based keep-alive mechanism incorporates feedback from network conditions and path state to determine when transmission is necessary. The system monitors metrics such as path quality, network events, and traffic patterns to trigger keep-alive messages only when needed, thereby maintaining reliability while minimizing energy consumption compared to static periodic approaches.
Solution Approach 2:
The system performs preliminary assessment of path health and network conditions before triggering keep-alive transmissions. By evaluating potential path failures or degradation in advance, the mechanism can proactively send keep-alive messages only when the assessment indicates risk, avoiding unnecessary transmissions while ensuring reliability when paths are compromised.
