IoT Device Three-Transmitter Relay Charging Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing IoT systems, when an IoT device is a charging target, relay mechanisms sometimes disable charging, leading to inefficiencies in data transmission to a base station.
Innovation Solution
The IoT device employs a three-transmitter system: one for direct data transmission to a base station, another for near-field communication with a neighboring device to relay data, and a third for transmitting communication cost bearer information, ensuring the user bears the relayed data's communication costs, with a subtracter in the core network adjusting charges accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is relayed by a neighboring device, then data transmission is enabled when direct transmission is not possible, but charging is disabled and communication cost bearing becomes unclear
Solution Approach 1:
The patent introduces a base station as an intermediary to manage the relay communication process. The base station receives relay indication information from the neighboring device, determines the original transmitting device, and manages the charging process. This intermediary role resolves the contradiction by enabling reliable relay transmission while preserving charging information through centralized management.
Solution Approach 2:
The patent implements a feedback mechanism where relay indication information is transmitted back to the base station after relay transmission occurs. This feedback loop allows the base station to identify that relay transmission has taken place, determine the original transmitting device, and apply appropriate charging. The feedback ensures charging information is not lost even when relay transmission occurs.
2Duration of action of moving object
If relay transmission is used to extend operational range, then devices with low battery can transmit data, but it is unclear who should bear the communication cost
Solution Approach 1:
The base station acts as an intermediary that receives relay indication information, determines the original transmitting device, and decides communication cost bearing. This resolves the ambiguity about who should pay by centralizing the decision-making process. The original transmitting device (even if it has low battery) can have its communication costs borne by itself or by the neighboring device based on base station policy.
Solution Approach 2:
The relay indication information serves as feedback that enables the base station to trace back the original transmitting device and determine appropriate charging. This feedback mechanism ensures that communication cost bearer information is preserved and properly assigned, preventing the loss of charging information that would otherwise occur in relay scenarios.
3Loss of information
If direct transmission is used, then charging can be properly implemented, but devices with low battery cannot transmit data
Solution Approach 1:
The base station as an intermediary enables both direct and relay transmission modes while maintaining proper charging. When direct transmission is not possible due to low battery, the base station receives relay indication information and can still implement charging by determining the original transmitting device. This resolves the contradiction by preserving charging information capability while enabling extended operational time through relay options.

AI summary
An IoT device for properly performing charging even when data from an IoT device is relayed and transmitted to a base station includes a first transmitter that directly transmits acquired data to the base station, a second transmitter that transmits the data to a neighboring device by near-field communication to relay the data by the neighboring device and transmit the data to the base station, and a third transmitter that transmits, to the base station, communication cost bearer information representing that the user of the IoT device bears the communication cost of the data relayed by the neighboring device and transmitted.
