Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multilink distribution and aggregation technologies face difficulties in quickly reflecting link status of other access networks at the transport or application layer and are restricted to TCP on the transport layer and HTTP on the application layer.
Innovation Solution
A multilink-based communication method that supports wireless communication systems, allowing for the selection and aggregation of paths based on operator management policies, application flow types, and access network path statuses, independent of transport or application layers, using a multilink adaptation layer to manage and split data traffic across multiple radio access networks.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multilink distribution and aggregation technology is used at the transport or application layer, then data transmission can be achieved, but the link status of other access networks cannot be reflected quickly and the system is restricted to TCP and HTTP protocols
Solution Approach 1:
The patent introduces a new dimension by implementing multilink functionality at the access network layer rather than being constrained to the transport or application layers. This dimensional shift allows the system to operate independently of specific protocols like TCP or HTTP, achieving protocol independence while maintaining efficient data transmission across heterogeneous networks.
Solution Approach 2:
The access network layer is designed to provide universal multilink distribution and aggregation capabilities that work across multiple protocols and access networks. This multi-functional approach enables the system to handle various types of traffic and protocols without being restricted to specific implementations, thereby improving adaptability.
2Productivity
If multiple access networks are used for data transmission, then data rate can be improved, but the complexity of managing and selecting paths increases
Solution Approach 1:
The patent introduces an intermediary mechanism at the access network layer that mediates between multiple access networks and the upper layers. This intermediary manages path selection, link status monitoring, and traffic distribution, thereby simplifying the complexity of managing multiple paths while maintaining high data rates through effective aggregation.
Solution Approach 2:
The system implements feedback mechanisms that continuously monitor link status across multiple access networks. This feedback information is used to dynamically adjust path selection and traffic distribution, enabling the system to optimize data transmission rates while automatically managing the complexity of multiple paths without requiring manual intervention.
3Reliability
If link status is monitored at the transport or application layer, then transmission reliability can be maintained, but the response time to link changes is delayed
Solution Approach 1:
The patent implements preliminary action by monitoring link status at the access network layer, which is lower in the protocol stack than the transport or application layers. This early monitoring allows the system to detect link status changes before they affect higher layers, enabling faster response times while maintaining transmission reliability through proactive path adjustments.
