9 Capability requirements for support of e-health monitoring services
9.1 Introduction to the EHM capabilities
The following subclauses describe the EHM capability requirements according to the IoT reference
model [ITU-T Y.2060].
The EHM reference model, shown in Figure 9-1, exhibits two types of capabilities, EHM essential
IoT capabilities derived from the EHM service requirements and EHM not essential IoT
capabilities. They are located at the various layers of the IoT reference model [ITU-T Y.2060].
NOTE 1 – The EHM reference model excludes on purpose the IoT capabilities which are not related to the
specific support of EHM services. Consequently, this clause does not cover other IoT common capabilities
which are still necessary to support EHM services.
NOTE 2 – The distinction between EHM essential IoT capabilities and EHM not essential IoT capabilities
concerning the capabilities described in each of the following subclauses is beyond the scope of this
Recommendation.
In Figure 9-1, rounded rectangles represent layers (i.e., application layer, service support and
application support (SSAS) layer, network layer, device layer) according to the IoT reference
model; rectangles represent capabilities provided by the various layers of the IoT reference model,
as well as security and management capabilities.

9.2 Capabilities of the application layer
9.2.1 Information sharing
Information sharing is one of the basic capability requirements for EHM. According to the service
requirements 8.6.1(1), 8.2.1(3), 8.2.2(3), 8.2.3(3), the application layer is required to provide
standard interfaces and policy-based mechanisms to enable the sharing of EHM information among
different EHM services. Examples of policy rules for policy-based mechanisms include, but are not
limited to, government rules, privacy rules, commercial agreements between application providers
and so on.
9.2.2 Accounting related information provision
According to service requirements 8.6.2(2), 8.2.1(4), 8.2.2(4), the application layer is recommended
to report accounting related information to the SSAS layer. The accounting related information
includes, but is not limited to, application type (EHMH, EHMR and EHMT), the number of times
that the application is used, the time during which the application is used, etc.
