Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices experience reduced data transmission and reception speeds and quality of service when switching from device-to-device communication sessions due to reliance on access points, leading to service interruptions.
Innovation Solution
An electronic device is equipped with a processor to manage multiple communication schemes, allowing it to discover and establish a secondary communication session based on predetermined conditions during an ongoing primary session, ensuring seamless data transfer without relying solely on access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device transmits or receives data through the access point after the TDLS session ends, then the device can maintain connectivity, but the transmission speed and reception speed decrease
Solution Approach 1:
The electronic device performs preliminary actions by discovering the external device through a second communication scheme (such as Wi-Fi Direct) while the first session (TDLS) is still active. This allows the device to prepare alternative communication paths in advance, so when the TDLS session ends, the device can immediately switch to the second communication scheme without falling back to AP-based communication, thereby maintaining both connectivity and high transmission speed.
2Ease of operation
If the electronic device relies on access point for data transmission after session termination, then the device maintains simple operation, but the quality of service deteriorates
Solution Approach 1:
The electronic device performs self-service by autonomously managing multiple communication schemes. The processor automatically discovers external devices, establishes sessions, and switches between communication modes without user intervention. This maintains operational simplicity while ensuring high quality of service, as the device independently optimizes its communication path rather than relying on access point mediation.
3Device complexity
If the electronic device uses only one communication scheme, then the device structure remains simple, but the adaptability to different communication conditions decreases
Solution Approach 1:
The electronic device implements multi-functionality by supporting multiple communication schemes (TDLS and at least one other scheme like Wi-Fi Direct). The processor is configured to manage both schemes, discovering devices and establishing sessions through different protocols. This allows the device to adapt to various communication conditions and session requirements while maintaining relatively simple operation through automated scheme selection and switching.

AI summary
An electronic device is provided. The device includes a communication circuit and a processor configured to receive, in a connected state with an access point (AP), information on an external electronic device related to a first communication scheme and information on the external electronic device related to a second communication scheme different from the first communication scheme, set up a first session supported by the first communication scheme with the external electronic device, based on the information on the external electronic device related to the first communication scheme, discover the external electronic device, based on the information on the external electronic device related to the second communication scheme according to the electronic device satisfying a predetermined condition, set up a second session, based on data related to the second communication scheme, and transmit and/or receive the data through the second session.
