Terminal Status-Based Content Delivery via Low-Power Advertising Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In location-based services using short-range networks, terminals face high power consumption during scanning, leading to inefficient recognition of changes in status, resulting in the same service being provided regardless of terminal status changes, limiting personalized service delivery.
Innovation Solution
A terminal status-based content receiving method and apparatus that broadcasts an advertising packet with status information via a low-power short-range communication unit, allowing differential content to be received based on terminal status changes, enabling personalized services such as coupons or application join requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously performs scanning to recognize store information, then the recognition of store entry is achieved, but the power consumption increases significantly
Solution Approach 1:
Instead of the terminal actively scanning for store information (terminal as active scanner), the store's advertising packet actively broadcasts information to terminals (store as active broadcaster). This inversion of roles allows the terminal to passively receive information, significantly reducing power consumption while maintaining reliable store entry recognition.
Solution Approach 2:
The terminal performs scanning operations periodically rather than continuously. The advertising packet is broadcast at regular intervals, and the terminal checks for changes in status information at each period, reducing overall power consumption while ensuring timely detection of store entry events.
2Device complexity
If the terminal provides the same service irrespective of status changes, then the system complexity is reduced, but the service personalization is lost
Solution Approach 1:
The service system adapts its behavior based on local conditions - specifically the terminal's status information. Different services are provided based on the terminal's state (e.g., connected vs. disconnected, battery level, location), allowing personalization without requiring a completely complex system architecture. The status information acts as a local qualifier that determines service type.
3Use of energy by moving object
If the advertising packet is broadcast for a short duration, then the power consumption of broadcasting is reduced, but the content delivery reliability is compromised
Solution Approach 1:
Instead of relying on continuous or frequent broadcasting to ensure delivery, the system uses a change-detection mechanism. The terminal monitors for changes in status information in the advertising packet, and the external device detects when the terminal has entered the store based on these changes. This substitution of continuous transmission with event-driven detection improves reliability while reducing power consumption.

AI summary
A terminal status-based content receiving method and an apparatus that receives a differential content based on a change in a status of a terminal are provided. The content receiving apparatus includes a low-power short range communication unit, and a controller configured to determine a status of the terminal, to include status information of the terminal in an advertising packet so as to periodically broadcast the advertising packet through the low-power short range communication unit, and to receive content corresponding to the status of the terminal from an external device that scans the advertising packet.
