Beacon Device Connection Management for BLE Signal Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Once a communication connection is established between a terminal device and a beacon device using Bluetooth Low Energy (BLE), the beacon device cannot broadcast its signal again, preventing other terminal devices from identifying it.
Innovation Solution
The beacon device releases the communication connection immediately after receiving data from a terminal device, processes the data, and then re-establishes a connection to notify the terminal device of the processing completion, allowing it to receive the results while minimizing connection time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication connection is established between a terminal device and a beacon device using Bluetooth Low Energy (BLE), then data transmission can be performed, but the beacon device cannot broadcast its signal anymore, preventing other terminal devices from identifying it
Solution Approach 1:
The patent applies the dynamics principle by making the communication connection state changeable between connected and disconnected. The beacon device dynamically transitions from a connected state (for data transmission) to a disconnected state (for signal broadcasting), allowing both functions to operate at different times. This resolves the contradiction by enabling the beacon to adapt its connection state based on operational needs.
Solution Approach 2:
The patent implements periodic action through the cyclic alternation between connection establishment and disconnection. The beacon device establishes connections periodically for data transmission, then disconnects to broadcast signals, creating a rhythmic pattern of connection-disconnection-broadcasting. This periodic behavior allows the beacon to serve multiple terminal devices while maintaining signal availability.
2Reliability
If the beacon device maintains a communication connection with a terminal device, then data can be transmitted reliably, but the beacon signal cannot be broadcast to other terminal devices
Solution Approach 1:
The beacon device dynamically adjusts its connection state to balance data transmission reliability with the ability to serve multiple terminal devices. By transitioning from a persistent connected state to a dynamic state that alternates between connection and disconnection, the beacon can reliably transmit data to one device at a time while remaining accessible to multiple devices through periodic broadcasting.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining the beacon's operational presence through periodic signal broadcasting even when disconnected from a specific terminal device. The beacon continuously performs its primary function of broadcasting signals to multiple devices, while intermittently establishing connections for data transmission, thus never ceasing its useful action.
3Productivity
If the beacon device establishes a communication connection with a terminal device, then data can be received and processed, but the beacon cannot broadcast signals during the connection
Solution Approach 1:
The patent applies periodic action by alternating between data reception periods (when connected) and signal broadcasting periods (when disconnected). This time-division approach allows the beacon to dedicate specific intervals to data processing while maintaining signal availability during other intervals, thus balancing productivity with minimal time loss.
Solution Approach 2:
The beacon device dynamically switches between connection and disconnection states to optimize the balance between data processing and signal broadcasting. By making the connection state flexible and time-varying rather than fixed, the system can maximize data processing opportunities when needed while ensuring signal broadcasting occurs during connection-free periods.
Data Source
AI summary
A wireless communication system, and an apparatus and method for controlling communication connections with a plurality of user terminals in the system are disclosed. The terminal device includes a communication unit, a storage unit, and a control unit. The communication unit receives a signal, broadcast by at least one beacon device, via wireless communication. The storage unit stores data that is transmitted and received to and from the beacon device. The control unit is functionally connected with the communication unit, scans a signal transmitted from the beacon device, performs an operation for a communication connection with the beacon device using the scanned signal, receives a bit mask via the communication unit and also stores the bit mask in the storage unit when the communication connection has been established, transmits data to the beacon device via the communication unit, and immediately releases the communication connection.
