Low-Power Terminal Advertising Packet Broadcasting for Content Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for receiving beacon packets in Wi-Fi terminals result in high power consumption due to the need for continuous Wi-Fi scanning, making it difficult to receive marketing information while in motion or in low-power states.
Innovation Solution
A low-power short-range communication unit, such as Bluetooth Low Energy (BLE), is used to broadcast advertising packets at regular intervals, allowing terminals to connect with service providers and receive content while minimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If Wi-Fi scanning is performed continuously to receive beacon packets, then marketing information can be received, but power consumption increases
Solution Approach 1:
The patent introduces a low-power short-range communication unit as an intermediary device that continuously broadcasts advertising packets containing terminal information. This mediator enables service providers to scan and connect to terminals without requiring terminals to perform high-power Wi-Fi scanning, thus resolving the contradiction between information reception and power consumption.
2Use of energy by moving object
If scan operation cycle is extended to reduce power consumption, then terminal can save battery, but user cannot receive beacon packets while in motion
Solution Approach 1:
The patent inverts the traditional scanning paradigm: instead of terminals scanning for service providers (active scanning), the terminal broadcasts its information via low-power communication and service providers scan for terminals (passive scanning from terminal perspective). This inversion allows terminals to maintain low power consumption while ensuring reliable connection establishment even when in motion.
3Ease of operation
If Wi-Fi is kept always on for seamless information reception, then marketing information can be received without interruption, but current consumption increases
Solution Approach 1:
The patent implements periodic broadcasting of advertising packets by the low-power short-range communication unit at regular intervals. This periodic action ensures that terminal information is continuously available to service providers without requiring the terminal to keep Wi-Fi always on, achieving seamless information reception with reduced current consumption.

AI summary
An apparatus and a method for receiving content in a terminal, by which the terminal can receive, with low power consumption, content from an adjacent service provider by using a wireless communication technology. A low-power short-range communication unit; and a controller for controlling the low-power short-range communication unit to broadcast an advertising packet including information of the terminal at regular intervals, and control the low-power short-range communication unit so as to connect to a particular service provider which has scanned the advertising packet. A control operation is then performed so as to receive content from the particular service provider.
