            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.
