Solution Overview

Problem

In multi-link communication scenarios using TDD technology, devices face scheduling conflicts that reduce link stability and bandwidth utilization, particularly in scenarios where multiple connections require different data pressures and response speeds.

Innovation Solution

The method involves a first device rationally arranging anchor points and bandwidth duty cycles across links based on network requirements, using BLE5.0 and BLE5.1 protocols to configure connection parameters, ensuring conflict-free scheduling and optimizing bandwidth allocation by determining the moving position of link anchor points according to instantaneous reference points and window moving distances.

Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent segments the time-domain resources by introducing connection intervals and connection events for each link, allowing independent scheduling of each link's data transmission. By dividing the overall time resource into separate connection intervals for different links, the system avoids scheduling conflicts while maintaining multiple connections, thus improving both bandwidth utilization and link stability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent dynamically adjusts connection parameters including connection intervals and anchor points based on real-time network conditions and data pressure requirements of different links. This dynamic adjustment allows the system to adaptively allocate time resources to different links according to their specific needs, preventing scheduling conflicts and maintaining stable connections

Inventive Principle:
Principle #15Dynamics

2Productivity

If connection parameters are updated frequently to optimize bandwidth allocation, then bandwidth utilization improves, but scheduling conflicts may increase

Engineering Contradiction:
Improvebandwidth utilizationVSAvoidscheduling stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the primary device receives data pressure information from secondary devices and uses this feedback to adjust connection parameters. The anchor point adjustment notification package contains feedback about data pressure conditions, enabling the system to optimize bandwidth allocation while maintaining scheduling stability through informed parameter updates

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary actions by pre-configuring connection intervals and anchor points before actual data transmission begins. By establishing these parameters in advance based on predicted data pressure patterns, the system can avoid scheduling conflicts during operation while maintaining optimal bandwidth utilization without frequent parameter changes

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided are a link processing method, a device and a storage medium. The method is applied in a network including a first device and two or more second device, where the first device is communicatively connected with the second devices via independent links. The method includes: the first device sending a connection parameter updating request to at least one of the second devices; determining a moving position of a link anchor point according to an instantaneous reference point and a window moving distance when the second device confirms the connection parameter updating request; and adjusting a connection parameter of the link according to the moving position of the link anchor point. According to the present application, the scheduling of multiple links can be rationally arranged, thereby avoiding scheduling conflicts among the links and improving stability of the links.
