Bluetooth Link Management for Multi-Device Acknowledgement Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth network environments, devices transmitting data packets to multiple external devices face increased resource and power consumption, as well as complexity, due to the need to establish multiple links, leading to performance degradation and longer data packet transmission times as the number of devices increases.
Innovation Solution
An electronic device with a wireless communication circuit and processor supports Bluetooth networks, generating separate links with external devices, allowing one device to monitor and negotiate timing for response messages, thereby reducing unnecessary resource usage and optimizing data packet transmission by allowing secondary devices to transmit acknowledgement messages independently of primary devices.

Engineering Contradiction Analysis
1Productivity
If multiple links are established to transmit data packets to multiple external devices, then data transmission capability is improved, but resource consumption and power consumption increase
Solution Approach 1:
The patent segments the acknowledgment function by allowing different devices (primary and secondary earphones) to independently send ACK messages to the source device. This segmentation enables parallel acknowledgment transmissions, reducing the source device's waiting time and improving overall data transmission capability without requiring additional resource allocation for sequential processing.
Solution Approach 2:
Secondary external devices (e.g., secondary earphone) are empowered to independently monitor the communication link and send acknowledgment messages without requiring the source device to directly manage each device individually. This self-service approach reduces the source device's processing burden and resource consumption while maintaining reliable multi-device communication.
2Productivity
If multiple links are established to transmit data packets to multiple external devices, then data transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal acknowledgment mechanism where both primary and secondary external devices follow the same protocol to send ACK messages to the source device. This multi-functionality allows the source device to handle multiple acknowledgment streams using a single, standardized process, reducing complexity in link management while maintaining the ability to communicate with multiple devices simultaneously.
3Productivity
If multiple links are established to transmit data packets to multiple external devices, then data transmission capability is improved, but transmission time increases
Solution Approach 1:
The patent employs periodic acknowledgment transmissions where multiple external devices send ACK messages at predetermined time intervals after receiving data packets from the source device. This periodic action ensures that the source device receives confirmations from all devices in a structured, time-efficient manner, reducing overall transmission time while maintaining reliable communication across multiple links.

AI summary
An electronic device is provided. The electronic device includes a wireless communication circuit that supports a Bluetooth network, at least one processor operatively connected to the wireless communication circuit, and a memory operatively connected to the at least one processor. The memory stores instructions that, when executed, cause the at least one processor, through the wireless communication circuit, to generate a first link with a first external electronic device based on the Bluetooth network, generate a second link with a second external electronic device based on the Bluetooth network, transmit information to the second external electronic device through the second link, wherein the information is used by the second external electronic device to monitor the first link, negotiate timing for transmitting a response message with the second external electronic device, receive a data packet from the first external electronic device, and transmit a response message to the first external electronic device in response to the data packet based on the negotiated timing.
