WiFi Access via Short Message Query
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accessing the internet through shared wireless access points when mobile data is unavailable or unsupported, as they cannot obtain the necessary login passwords.
Innovation Solution
A method and device that allow users to search for wireless access points, generate and send query requests via a short message channel to obtain access information, including login passwords, even without mobile data, by utilizing an access point information storage server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile data is used to obtain login password from access point information storage server, then access information can be obtained, but mobile data availability is required which limits usability in regions without mobile data support
Solution Approach 1:
The patent introduces a short message channel as an intermediary communication path between user equipment and the access point information storage server. This mediator allows access information retrieval without requiring mobile data connectivity, thus resolving the contradiction between reliable access information acquisition and adaptability to regions without mobile data support
Solution Approach 2:
The patent changes the communication parameter from mobile data channel to short message channel. This parameter change enables the system to operate in environments where mobile data is unavailable, while still maintaining the ability to retrieve access information from the server
2Adaptability or versatility
If short message channel is used to query access information, then mobile data availability is not required, but the system complexity increases due to multiple communication channels
Solution Approach 1:
The user equipment is designed with multi-functionality to support both mobile data communication and short message communication. This universal design allows the device to adapt to different network environments without requiring separate dedicated devices, thus managing system complexity while maintaining high adaptability
3Reliability
If access information is transmitted through short message, then security is improved by avoiding mobile data channels, but message channel capacity limitations may affect information transmission
Solution Approach 1:
The patent extracts only the essential access information (login password and related parameters) needed for WiFi connection into the short message. By taking out only the necessary data elements rather than transmitting complete network configuration data, the system maintains security through the short message channel while respecting message capacity limitations
Data Source
AI summary
A method for obtaining and providing access information of a wireless access point, comprises: searching for wireless access points to obtain identification information of one or more wireless access points; generating a query request short message according to the identification information of the one or more wireless access points; sending the query request short message via a short message channel; receiving an access information short message including access information of the one or more wireless access points which is returned by a network device in response to the query request short message. When mobile data of a user equipment of the user is unavailable or when the user equipment does not support mobile data, the user equipment is able to send a query request via a short message and obtain information, such as a login password for accessing a wireless access point, from an access point information storage server.
