Wi-Fi Direct Session Deferment via Provision Discovery Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Wi-Fi Direct services (WFDS) systems, there is a lack of efficient methods for controlling session connections, particularly when session connections are configured to be deferred, leading to inconsistencies and limitations in information transmission regarding session status between devices.
Innovation Solution
A method is introduced that involves a first device receiving a provision discovery request frame with advertisement identifier information from a second device and transmitting a provision discovery response frame, where the auto_accept value in the AdvertiseService method is set to 'False', allowing the first device to defer a session related to the advertisement ID and include information about the session deferment in the response frame, which can be transmitted to an application service platform and subsequently to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a device automatically accepts session requests in WFDS systems, then session establishment speed is improved, but user control and awareness of service acceptance deteriorates
Solution Approach 1:
The system dynamically adjusts the session acceptance behavior based on user preferences and service types. The auto_accept parameter can be set to True or False, allowing the device to switch between automatic acceptance and manual confirmation modes, providing flexibility in balancing speed and user control.
Solution Approach 2:
The system provides feedback to the user about incoming session requests through notifications and prompts. When auto_accept is False, the user is informed of the session request and can make an informed decision, maintaining awareness while still allowing for automatic acceptance when desired.
2Use of energy by moving object
If a device defers session requests without providing status information, then device resource usage is reduced, but information transmission completeness deteriorates
Solution Approach 1:
The provision discovery response frame acts as an intermediary carrier that transmits session deferment status information from the advertiser device to the seeker device. This allows the system to maintain resource efficiency while ensuring that session status information is not lost, as the deferment status is explicitly communicated through the response frame.
3Device complexity
If session deferment information is not transmitted between devices, then communication protocol complexity is reduced, but session management reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by including session deferment information in the provision discovery response frame before the actual session establishment. This allows both devices to be aware of the deferment status in advance, enabling proper session management without requiring complex additional communication protocols.

AI summary
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting, if an advertiser device is set to delay a session with respect to the request for a session from a seeker device, session delay information to the seeker device in a method for setting Wi-Fi direct service communication and to an apparatus therefor.
