Ambient-Powered IoT Paging With No-Response Timer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient-powered IoT devices face challenges in efficiently handling paging requests due to their limited energy resources, particularly in harsh environments, requiring methods to optimize energy usage and response times.
Innovation Solution
Implementing a paging response configuration in ambient-powered IoT devices to ignore further paging requests for a defined no-response time, allowing devices to conserve energy by selectively responding to specific or non-specific paging requests based on a configured response time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AIoT devices respond to all paging requests, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The device dynamically adjusts its paging response behavior based on the no-response timer state. When the timer is running, the device ignores paging requests; when expired, it responds normally. This dynamic adjustment resolves the contradiction by making the response behavior adaptive rather than static, ensuring reliability when needed while conserving energy during high-traffic periods.
Solution Approach 2:
The system changes the response parameter (ignore vs. respond) based on the timer state. By introducing the no-response timer as a control parameter, the device can switch between two operational modes: ignoring paging requests during the timer period and responding after expiration. This parameter-based control resolves the contradiction between reliability and energy consumption.
2Use of energy by moving object
If AIoT devices ignore paging requests during no-response time, then energy consumption is reduced, but response time increases
Solution Approach 1:
The no-response timer creates a periodic pattern of ignoring and responding to paging requests. Instead of continuously responding, the device enters periodic ignore periods followed by responsive periods. This periodic action reduces overall energy consumption while ensuring that the device becomes responsive again after the timer expires, thus managing the trade-off between energy savings and response time.
3Reliability
If AIoT devices respond to every paging request, then communication reliability is maintained, but device complexity increases due to timer management
Solution Approach 1:
The paging response functionality is segmented into two distinct modes controlled by the no-response timer: ignore mode and respond mode. This segmentation simplifies the decision-making process within the device - it only needs to check the timer state to determine which mode to operate in, rather than implementing complex algorithms to evaluate each paging request individually.

AI summary
Methods, systems, and devices for an ambient powered internet-of-things (AIoT) device paging. In some implementations, a paging request message is received, and a response is transmitted to the paging request message based on a paging response configuration. In some implementations, a no-response time is started based on responding to the paging request message, wherein the AIoT device ignores further paging request messages until the no-response time has elapsed. In some implementations, a no-response time is started based on responding to the paging request message, wherein the AIoT device ignores further paging request messages that are of a particular type and does not ignore further paging requests that are not of the particular type, until the no-response time has elapsed.
