Short-Range Connection Speed Optimization via Stored Network Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi Hotspot network connection techniques, such as Hotspot 2.0, face usability issues due to delayed network discovery and connection processes, particularly in crowded areas, and inefficient network updates, which degrade user experience and network efficiency.
Innovation Solution
The method involves an electronic device selectively performing information exchange operations with an information server to optimize connection speed by classifying external devices based on service provider and venue, using beacon frames or probe response frames to identify service providers and venues, and updating network information accordingly, thereby minimizing unnecessary information exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the ANQP query/response operation is performed for each venue to update network information, then the network information is kept updated, but the connection speed is degraded
Solution Approach 1:
The electronic device performs the ANQP query/response operation in advance when first connecting to an AP, stores the obtained network information, and then uses this stored information for subsequent reconnections to the same AP. This preliminary action eliminates the need to perform the operation again during reconnections, thus resolving the contradiction between keeping network information updated and maintaining fast connection speed.
2Loss of time
If the ANQP query/response operation is skipped during reconnection to improve connection speed, then the connection speed is improved, but the network information may become outdated
Solution Approach 1:
The electronic device uses its own stored network information (obtained previously through ANQP query/response) to facilitate reconnections without needing to contact the information server again. The device serves itself by utilizing previously acquired information, thereby achieving fast reconnection while maintaining information availability for the connection process.
3Reliability
If numerous client terminals exist in a specific hotspot region, then the network coverage is improved, but the ANQP query/response operation causes significant delays
Solution Approach 1:
The electronic device performs the ANQP query/response operation once during initial connection to the AP, stores the network information locally, and then uses this stored information for all subsequent reconnections. This approach eliminates repeated information exchange operations in crowded hotspot regions with multiple client terminals, significantly reducing connection delays while maintaining reliable network coverage.

AI summary
A method for connecting short-range communication in an electronic device, and the electronic device, in which an information exchange operation with an information server may be selectively performed are provided. The method includes detecting second identification information for identifying a service venue of a service provider from discovery information received from a first external device and connecting communication with the first external device by using network information of the first external device, which is stored in the electronic device, if the detected second identification information exists in the electronic device. Other embodiments are also possible.
