Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The congestion on communication links between edge gateways and internet of things platforms due to the increased computing capability and large quantity of internet of things devices accessing them.
Innovation Solution
Establish multiple communication links between edge gateways and internet of things platforms using different gateway identifiers and port numbers, and implement load balancing and dynamic allocation of communication links based on device quantity and frequency, with random or sequential selection policies for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication link is used between edge gateway and internet of things platform, then device complexity is reduced, but communication link congestion occurs due to large quantity of devices
Solution Approach 1:
The patent segments the single communication link into multiple communication links between the edge gateway and the internet of things platform. The gateway establishes multiple links with different gateway identifiers to distribute device data across these links, preventing congestion on any single link while maintaining manageable complexity through systematic link management.
2Reliability
If multiple communication links are established to avoid congestion, then communication reliability is improved, but device complexity and resource allocation difficulty increase
Solution Approach 1:
The patent implements dynamic link management where the edge gateway can establish, activate, and manage multiple communication links flexibly. The gateway determines when to establish additional links based on device quantity and data transmission needs, and can dynamically allocate different gateway identifiers to different links, allowing the system to adapt to changing conditions without excessive complexity.
Solution Approach 2:
The patent changes the gateway identifier parameter across multiple communication links. By using different gateway identifiers (first gateway identifier, second gateway identifier, etc.) for different links, the system distinguishes and manages multiple links effectively. This parameter variation enables the gateway to track and control data flow across multiple links without requiring complex management mechanisms.
3Productivity
If multiple gateway identifiers are used for different communication links, then link discrimination and load distribution are improved, but information management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the edge gateway monitors device data quantities and communication link status. Based on this feedback, the gateway determines when to establish new communication links with different gateway identifiers and when to activate existing links, ensuring efficient load distribution while maintaining clear tracking of identifier usage through continuous monitoring and adjustment.

AI summary
A data transmission method includes establishing a first communication link with an internet of things platform; sending a multi-link access request to the internet of things platform over the first communication link, where the multi-link access request carries a first quantity of internet of things devices accessing an edge gateway; receiving link establishment information that is sent by the internet of things platform and that corresponds to at least one second communication link; establishing the at least one second communication link with the internet of things platform based on the link establishment information corresponding to the at least one second communication link; and performing data transmission with the internet of things platform over the first communication link and the second communication link.
