Solution Overview

Problem

Existing wireless communication systems face inefficiencies in reconnecting Wi-Fi connections due to errors, leading to delayed file transmission and user intervention, as error detection and tolerance mechanisms are not timely or automated.

Innovation Solution

A transmission control method that allows devices to detect errors in Wi-Fi connections and automatically send error information through secondary communication channels like Bluetooth, enabling timely error tolerance processing and reconnection without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the device waits for user operation to re-establish Wi-Fi connection after error, then the system complexity remains low, but the connection establishment efficiency deteriorates

Engineering Contradiction:
Improveconnection establishment efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by establishing a Bluetooth connection before Wi-Fi connection is needed. When Wi-Fi error occurs, the device can immediately use the pre-established Bluetooth connection to notify the peer device and initiate reconnection, eliminating the need for user intervention and significantly improving connection establishment efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanism where error information is automatically detected and transmitted through Bluetooth to the peer device. This feedback loop enables both devices to sense errors in real-time and automatically trigger reconnection procedures, transforming the manual reconnection process into an automated system

Inventive Principle:
Principle #23Feedback

2Reliability

If automatic error detection and notification system is implemented, then the connection maintenance efficiency improves, but the device complexity increases

Engineering Contradiction:
Improveconnection maintenance efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses Bluetooth as an intermediary communication channel between Wi-Fi devices. When Wi-Fi connection fails, Bluetooth serves as the mediator to transmit error notifications and coordinate reconnection between the two devices, enabling automatic error handling without significantly increasing overall system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies beforehand cushioning by maintaining a Bluetooth connection as a backup communication path. This备用 channel is established in advance to cushion against Wi-Fi connection failures, ensuring that error notification and recoordination can proceed automatically even when the primary Wi-Fi connection is compromised

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Embodiments of this application provide a transmission control method and a device, and relate to the field of communications technologies, so that devices of both parties can detect, in time, that an error occurs on a Wi-Fi connection, and perform error tolerance processing in time. A specific solution includes: sending/receiving, by a first device, first data to/from a second device through a first communication connection; in a process in which the first device sends/receives the first data to/from the second device through the first communication connection, detecting, by the first device, that an error occurs on the first communication connection; and sending, by the first device, error information of the first communication connection to the second device through a second communication connection, where the second communication connection is different from the first communication connection, and the error information is used to indicate that the error occurs on the first communication connection.
