Dynamic Connectivity System Idle Period Ping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for uploading data from in-vivo devices to the cloud face challenges in maintaining continuous network connectivity, particularly during idle periods, leading to potential hotspot termination and delays in data transfer.
Innovation Solution
A Dynamic Connectivity System (DCS) that includes a patient module for data communication with in-vivo devices and a gateway device providing an access point, which sends pinging signals during idle periods to prevent hotspot termination and prioritizes maintaining network connectivity, allowing for seamless data upload and switching between client and access point modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the access point is configured to terminate after an idle period to save energy, then energy consumption is reduced, but network connectivity is interrupted and data transfer is delayed
Solution Approach 1:
The system implements periodic ping signals sent from the patient module to the gateway device during idle periods. This periodic action keeps the access point alive by simulating active communication, preventing termination while consuming minimal energy compared to continuous data transmission.
Solution Approach 2:
The patient module automatically sends ping signals without external intervention to maintain the access point connection. This self-service mechanism ensures continuous connectivity during idle periods without requiring manual configuration or external control signals.
2Reliability
If the access point remains active continuously to maintain network connectivity, then data transfer reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous operation, the system uses periodic ping signals at predetermined intervals during idle periods. This maintains the access point connection with minimal energy expenditure, avoiding the need for continuous data transmission while preventing termination.
Solution Approach 2:
The system dynamically changes the communication parameter from continuous data transmission to periodic ping signals during idle periods. This parameter change reduces energy consumption while maintaining the connection state, allowing the access point to remain active without constant resource usage.
3Productivity
If data is uploaded in large chunks during active periods, then data transfer efficiency is improved, but the idle period increases and risks hotspot termination
Solution Approach 1:
The system sends periodic ping signals during the idle period after large data chunk uploads. This periodic action keeps the access point alive throughout the extended idle period, allowing efficient bulk data transfer without risking connection termination due to the prolonged inactivity.
Solution Approach 2:
The system performs preliminary data upload in large chunks when the connection is active, then uses periodic ping signals during the subsequent idle period to maintain connectivity. This preliminary action strategy maximizes data transfer efficiency while preventing connection loss during the inevitable idle period.

AI summary
A Dynamic Connectivity System (DCS) comprising a patient module configured for communication with an in-vivo device and with at least one additional device; the DCS further comprises a gateway device configured for providing an access point for the patient module for accessing a network; the access point is configured for termination after an idle period of predetermined idle time, and the patient module is configured for uploading data to the network via the mobile device during a non-idle period of the gateway device; the patient module is also configured for sending, during the idle period, a pinging signal to the mobile device different from the data, the pinging signal having a period time shorter than the predetermined idle time, thereby interrupting the idle period and preventing termination of the access point.
