Wireless Access Point Login via Encrypted Short Message
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing wireless access points require mobile data or a cellular network connection, which is not feasible when these resources are unavailable, preventing users from connecting to wireless access points.
Innovation Solution
A method involving encoding identification information of wireless access points into a preset data short message format, sending this information via a short message to a designated network device, and receiving encoded access information back, allowing connection without mobile data or cellular network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile data or cellular network connection is used to obtain login password, then access to wireless access point is enabled, but the system cannot operate when mobile data is exhausted or cellular network is unavailable
Solution Approach 1:
The patent introduces a short message service (SMS) as an intermediary communication channel between the terminal device and the access point information storage server. This intermediary allows the system to obtain login passwords without relying on mobile data or cellular network connections, thereby resolving the contradiction between access reliability and network environment adaptability.
2Ease of operation
If login password is required to connect to wireless access point, then network security is maintained, but user's network access requirements cannot be satisfied when password is unavailable
Solution Approach 1:
The patent implements preliminary action by pre-storing access point information including login passwords on a server before the terminal device needs to connect. When the user wants to connect, the terminal device queries the server for the stored information and receives the password, eliminating the need for manual password entry and ensuring connection reliability while maintaining ease of operation.
3Device complexity
If access point information is transmitted in plain text, then transmission simplicity is achieved, but information security is compromised
Solution Approach 1:
The patent applies parameter changes by transforming the transmission format of access point information from plain text to encrypted format. The terminal device and server use encryption algorithms to encode the information before transmission and decode it after reception, maintaining transmission simplicity while significantly improving information security by preventing unauthorized access during transmission.
Data Source
AI summary
Disclosed are methods, devices and media for obtaining and for providing access information of wireless access points. The method comprises: searching for wireless access points to obtain identification information of one or more wireless access points; encoding the identification information of the one or more wireless access points according to a preset data short message encoding format to generate a query request data short message; sending the query request data short message to a designated network device; and receiving an access information data short message which is returned by the designated network device in response to the query request data short message and is encoded and generated according to the preset data short message encoding format. Thus, the terminal device is able to access the wireless access point when mobile data is unavailable, and security of information during transmission can also be guaranteed.
