Aggregated Link Layer Message for Fast BLE Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current short-range communication protocols, such as Bluetooth Low Energy (BLE), require a predefined flow of events and messages for connection establishment, leading to prolonged connection times and a poor user experience.
Innovation Solution
Implementing a fast connection process that utilizes either an out-of-band (OOB) or over-the-air (OTA) exchange of aggregated connection information to establish a short-range communication link, reducing the need for multiple individual messages and enabling faster connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predefined flow of events and messages is used for connection establishment, then the connection is stable and reliable, but the connection establishment time is prolonged
Solution Approach 1:
The patent applies preliminary action by exchanging connection information and capabilities (such as supported features, data lengths, and PHY capabilities) before the actual connection establishment. This allows both devices to have the necessary information ready in advance, enabling faster connection setup without compromising reliability, as the predefined flow can be executed more efficiently with pre-shared information.
Solution Approach 2:
The patent merges multiple individual messages into a single aggregated link layer message that contains a complete set of connection information. This consolidation reduces the number of message exchanges required during connection establishment, significantly reducing connection time while maintaining the stability and reliability ensured by the comprehensive information exchange.
2Loss of information
If multiple individual messages are exchanged for connection establishment, then complete connection information is transmitted, but the number of messages increases connection establishment time
Solution Approach 1:
The patent merges multiple individual messages containing connection information into a single aggregated link layer message. This message includes a complete set of connection parameters such as supported features, maximum data lengths, and PHY capabilities. By transmitting all this information in one message rather than multiple separate messages, the patent reduces message exchange time while ensuring complete information transfer.
3Loss of time
If a fast connection process is implemented, then connection establishment time is reduced, but compatibility with standard protocols must be maintained
Solution Approach 1:
The patent implements a fast connection process that is universally compatible with standard Bluetooth Low Energy protocols. The aggregated link layer message format and the fast connection methodology are designed to work within the existing BLE framework, ensuring that devices implementing this fast connection process can interoperate with standard BLE devices while achieving reduced connection establishment times.
