Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network connection methods for mobile robots struggle with rapid deployment in scenarios where network credentials are dynamically updated or changed, leading to difficulties in maintaining secure and flexible network connections.
Innovation Solution
A method and apparatus that determine a preset network credential update condition, send an updated credential using a spare connection mode, and establish a connection with the mobile terminal when the credential matches, utilizing techniques like LoRa for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network credentials are dynamically updated for security, then network security is improved, but connection stability deteriorates as mobile terminals may lose network access during credential transitions
Solution Approach 1:
The system performs preliminary actions by notifying mobile terminals of upcoming credential changes in advance through a spare connection channel before the actual credential update occurs on the target network, allowing terminals to prepare for the transition and maintain continuous connectivity
Solution Approach 2:
A spare connection mode acts as an intermediary between the mobile terminal and the target network during credential transitions. This alternative communication path delivers credential update notifications and maintains connectivity when the primary target network connection is interrupted or unavailable
2Reliability
If network credentials are updated frequently to maintain security, then network security is improved, but deployment efficiency deteriorates due to increased reconnection overhead
Solution Approach 1:
The system implements feedback mechanisms where mobile terminals report their credential update status and connection state back to the server. This feedback loop enables the server to optimize credential update timing and notify only affected terminals, reducing unnecessary reconnection operations and improving deployment efficiency
Solution Approach 2:
By delivering credential update notifications through the spare connection mode before the actual credential change takes effect on the target network, the system enables mobile terminals to prepare and switch credentials proactively, avoiding connection interruptions and reducing reconnection overhead
3Stability of the object's composition
If a spare connection mode is introduced to maintain connectivity during credential updates, then connection stability is improved, but device complexity increases due to multiple connection modes
Solution Approach 1:
The spare connection mode is designed with multi-functionality, serving both as a notification channel for credential updates and as a fallback communication path during transitions. This universal approach allows a single alternative connection mechanism to fulfill multiple roles, reducing the need for separate specialized systems and mitigating complexity increases

AI summary
Disclosed in the embodiments of the present disclosure are a method, apparatus and system for a network connection, and a server and a medium. The method may include: determining whether a preset network credential update condition is met, wherein a network credential indicated by the preset network credential update condition is used for establishing a connection of a target network; in response to determining that the preset network credential update condition is met, sending an updated network credential to at least one mobile terminal by using a preset backup connection method; receiving a connection request for the target network that is sent by a target mobile terminal; and in response to determining that the connection request for the target network matches the updated network credential, establishing the connection of the target network to the target mobile terminal.
