Short-Range Connection Establishment via BLE Advertising and Aggressive Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing short-range communication protocols, such as Bluetooth, require significant time to establish connections, leading to a poor user experience in time-sensitive applications like streaming services, as they rely on manual selection or periodic scanning methods that consume power and time.
Innovation Solution
Implementing an advertising scheme using Bluetooth Low Energy (BLE) for devices to rapidly identify each other and initiate a connection through a more aggressive paging and scanning mechanism, reducing the time needed to establish a Bluetooth connection by half compared to conventional methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual device selection is used to establish short-range connection, then user control is improved, but connection establishment time increases significantly
Solution Approach 1:
The system performs preliminary actions by continuously broadcasting advertisements and scanning for devices before a connection is actually needed. This allows devices to be pre-identified and pre-paired, so when connection is required, the establishment time is minimized while still maintaining user control through the pairing interface.
2Loss of time
If automated paging and scanning protocol is used to establish short-range connection rapidly, then connection establishment time is reduced, but power consumption increases
Solution Approach 1:
Instead of continuous broadcasting and scanning, the system uses periodic actions at optimized intervals. The advertisement broadcasting and page scanning occur at specific time intervals rather than continuously, reducing overall power consumption while still achieving rapid connection establishment when needed.
Solution Approach 2:
The system performs preliminary pairing and identification actions in advance, storing device information locally. This allows the actual connection establishment to be faster and more energy-efficient, as the heavy lifting of device discovery and authentication has already been completed beforehand.
3Extent of automation
If conventional Bluetooth paging protocol with predetermined time intervals is used, then automated connection is achieved, but connection establishment time remains significant (2-10 seconds)
Solution Approach 1:
The system changes the time interval parameter from conventional Bluetooth's predetermined intervals (resulting in 2-10 second connection times) to optimized, shorter intervals. By adjusting this critical parameter, the system achieves automated connection while reducing establishment time to under 1 second, maintaining automation while dramatically improving speed.

AI summary
Exemplary embodiments include a system having a first device and a second device that are configured to establish a connection via a short-range protocol. The first and second devices perform an advertisement process to automatically identify that the first and second devices are capable of establishing the connection, the advertisement process comprising one of the first device or second device broadcasting an advertisement and the other one of the first device or the second device scanning for the advertisement, wherein, upon the first and second devices identifying that they are capable of establishing the connection, the first and second devices perform a paging mechanism to establish the connection, the paging mechanism comprising one of the first device or the second device transmitting a page and the other one of the first device or the second device scanning for the page, wherein the page triggers an operation to establish the connection.
