BLE Beacon Transmission Control via Wi-Fi Coupling Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth Low Energy (BLE) systems face challenges in balancing power consumption and response time in BLE transmission and reception services, where continuous reception increases power consumption but intermittent reception may delay push notifications, and the lending of BLE transmitters can limit user access and lead to service inefficiencies.
Innovation Solution
A communication system that includes a portable terminal, a BLE terminal, a Wi-Fi access point, a BLE receiver, and a controller, where the portable terminal transmits personal attribute information to the controller via Wi-Fi, acquires identification information, and instructs the BLE terminal to start or stop BLE beacon transmission only during Wi-Fi coupling, reducing power consumption and improving response times by operating as a BLE transmitter rather than a receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If continuous BLE reception is implemented to ensure prompt push notifications, then response time is improved, but power consumption increases
Solution Approach 1:
The patent inverts the traditional BLE role assignment by making the portable terminal (previously a receiver) the transmitter of BLE beacons, while the information providing apparatus becomes the receiver. This role reversal allows the terminal to control beacon transmission based on Wi-Fi coupling status, enabling prompt responses only when power is available rather than continuously consuming power to monitor for beacons.
Solution Approach 2:
The system implements periodic BLE beacon transmission only during periods when Wi-Fi coupling is established. The terminal transmits beacons at intervals defined by the beacon interval parameter, but only activates this periodic transmission when powered and connected via Wi-Fi, rather than maintaining continuous transmission or reception.
2Adaptability or versatility
If BLE transmitter is lent to users for BLE reception service, then service accessibility is improved, but device complexity and management overhead increase
Solution Approach 1:
The portable terminal autonomously determines when to transmit BLE beacons based on its own Wi-Fi coupling status and power state, without requiring external control or management. The terminal self-manages the beacon transmission process, eliminating the need for lending/transceiving apparatus and reducing management complexity while maintaining service accessibility.
Solution Approach 2:
The portable terminal performs multiple functions: it acts as a Wi-Fi client for communication with the information providing apparatus, and simultaneously as a BLE beacon transmitter for proximity-based services. This multi-functionality eliminates the need for separate dedicated BLE transmitter devices, reducing overall system complexity while maintaining service versatility.
3Use of energy by moving object
If BLE beacon transmission is restricted to Wi-Fi coupling periods, then power consumption is reduced, but communication reliability may be affected
Solution Approach 1:
The system establishes Wi-Fi coupling in advance before BLE beacon transmission begins. The terminal must successfully connect to Wi-Fi and receive the beacon transmission activation command before it starts transmitting BLE beacons, ensuring that communication infrastructure is ready and power is available before proximity-based services activate.
Solution Approach 2:
The information providing apparatus monitors the terminal's Wi-Fi coupling status and provides feedback by sending activation commands. When Wi-Fi coupling is detected, the apparatus transmits a command to activate beacon transmission; when coupling is lost, it sends a deactivation command. This feedback mechanism ensures beacon transmission occurs only when communication reliability is guaranteed.
