Wi-Fi Roaming Group Information for Seamless Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi roaming technologies are limited to switching between access points (APs) with the same service set identification (SSID) and security type, restricting seamless communication as users move between different SSIDs and security types.
Innovation Solution
An electronic device equipped with a communication module, memory, and processor that generates roaming group information associated with a connected AP, allowing the device to identify and roam to a second AP with a different SSID and security type based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roaming is limited to APs with the same SSID and security type, then connection reliability is improved, but roaming versatility deteriorates
Solution Approach 1:
The patent changes the parameters used for AP selection by introducing a priority value system that overrides the traditional requirement for matching SSID and security type. The processor selects APs based on priority values assigned to different SSIDs and security type combinations, allowing seamless roaming between APs with different parameters while maintaining connection reliability.
2Stability of the object's composition
If the electronic device performs scan operations to find APs with the same SSID and security type, then connection stability is improved, but roaming speed deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing priority values for different APs before roaming is needed. When roaming is triggered, the processor uses these pre-computed priority values to immediately select the best AP without performing extensive scan and comparison operations, thus reducing roaming time while maintaining connection stability.
Solution Approach 2:
The patent introduces a priority value as an intermediary parameter that mediates between connection stability requirements and roaming speed requirements. Instead of directly comparing SSID and security type parameters during roaming, the system uses priority values to guide AP selection, simplifying the decision process and reducing roaming time while ensuring stable connections.
3Adaptability or versatility
If the device stores and processes roaming group information for multiple SSIDs and security types, then roaming adaptability is improved, but device complexity increases
Solution Approach 1:
The patent simplifies device complexity by changing the data structure from storing detailed AP configuration parameters to storing compact priority values. Instead of maintaining complex records of multiple SSIDs and security types with their associated credentials and settings, the system uses a simplified priority value system that is easier to store and process while achieving the same roaming adaptability.

AI summary
According to various embodiments, an electronic device may comprise a communication module, a memory, and a processor electrically connected with the communication module and the memory. The processor may be configured to perform a communication connection with a first access point (AP) of a first service set identification (SSID) and a first security type through the communication module, generate first roaming group information associated with the first AP, identify whether there is an AP having the first SSID and the first security type when roaming while performing the communication connection with the first AP through the communication module, and in response to being not identified the AP having the first SSID and the first security type, perform roaming from the first AP to a second AP which is identified based on the first roaming group information.
