1. Proposed Workitem: Direct-to-Cloud-Constrained Devices Brief Proposal

Proposal Editor: Michael J. Kirwan
Editor: Tim Frost
Date: September 30th, 2020
Version: 1.0
Domain: DEVices

2. The Problem

With WiFi and Bluetooth connectivity the end-user is either restricted to transferring data wherever a hub is located, or would need to carry a hub device wherever they go. Furthermore, pairing and configuration is an additional obstacle. It is desired that medical sensors are small and long-life battery powered. Therefore it is desired to define a lightweight approach for secure direct data transfer from such a constrained device to cloud.

3. Key Use Case

Sarah has tested positive for Covid-19. While in quarantine, her physician suggests she monitor her temperature and blood saturation. The device provided to Sarah is a wearable sensor(s). Sarah's has no fixed broadband connectivity in her home; however, her wide area connectivity (a.k.a. cellular) is good, which means that her physician can receive and monitor her condition while she is at home without any extra work for Sarah or her physician as long as the devices Sarah is using have connectivity.

Johnny is a person with Type 1 diabetes. He is required to monitor his glucose levels continuously. The device provided to Johnny is a wearable sensor. Johnny is frequently mobile and has wide area connectivity (a.k.a. cellular) so his data can be uploaded to a back-end service for viewing and analysis by his physician.

4. Standards and Systems

3GPP, NB-IoT, eMTC, CoAP, IEEE 11073-10206, HL7 FHIR, IP/UDP/DTLS

5. Discussion

IHE DEVices PCH program defines interoperable data models for and recommend transport for healthcare use-cases. This is a companion project to prior work that was captured PHD Observation Upload profile completed last year.

Enabling personal connected health device sensor data in a constrained device (simple device with a simple processor and battery constrained) to send its data directly over wide area networks, instead of via Bluetooth and WiFi, will provide a much more secure, trusted & direct path to providers and consumers of the data.
