WLAN SSID Encoding for Cross-Platform Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Wireless Local Area Networks (WLANs), SSIDs containing Chinese characters often result in messy code displays on terminal devices due to incompatible character encoding forms across different system platforms, leading to confusion and resource inefficiencies.
Innovation Solution
Encoding SSIDs according to preset character encoding forms for various system platforms, such as Windows and universal encoding forms, to generate compatible codes for broadcasting, allowing terminal devices to select and display SSIDs correctly, and calculating statistics for accurate network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SSIDs containing Chinese characters are broadcasted without encoding, then the SSID can be displayed on terminal devices, but messy code displays occur due to incompatible character encoding forms across different system platforms
Solution Approach 1:
The patent applies preliminary action by encoding the SSID in multiple character encoding forms (such as GBK, UTF-8, Big5) before broadcasting. The communication device prepares various encoded versions of the SSID in advance, so when terminal devices receive the broadcast, they can select the correctly decoded version based on their system platform's character encoding, thereby avoiding messy code displays and ensuring proper display across different platforms.
2Loss of information
If SSIDs are encoded for multiple system platforms, then proper display is achieved on diverse devices, but network resource usage increases due to broadcasting multiple encoded versions
Solution Approach 1:
The patent applies partial action by selectively encoding SSIDs in multiple character encoding forms only when necessary (i.e., when the SSID contains non-ASCII characters that may cause display issues). For simple ASCII SSIDs, only a single encoding is used. This approach ensures proper display accuracy for complex SSIDs while minimizing unnecessary network resource consumption for simple cases.
3Adaptability or versatility
If SSIDs are encoded for multiple system platforms, then proper display is achieved on diverse devices, but the complexity of the broadcasting process increases
Solution Approach 1:
The patent applies universality by implementing a unified encoding strategy that handles multiple character encoding forms (GBK, UTF-8, Big5, etc.) through a single multi-functional encoding module. This module can automatically select and apply appropriate encodings based on the SSID content, and the same module handles broadcasting for all platform types, thereby managing complexity through a universal solution rather than separate handling for each platform.

AI summary
The present disclosure discloses a method and a device for releasing an SSID in a WLAN, which serves to increase a probability that a terminal device displays the SSID properly. The method includes: encoding (S101, S301) a set SSID according to a character encoding form for a variety of preset system platforms, to generate an SSID code suitable for the variety of system platforms; and broadcasting (S102, S203, S302) the generated SSID code suitable for the variety of system platforms in the WLAN. The present disclosure may increase a probability that a terminal device receives an SSID code which may be properly displayed in local, so as to increase a probability that a terminal device displays the SSID properly.
