Unleashing the potential of the Internet of Things 3
EHM services involve capabilities at all layers of the IoT reference model [ITU-T Y.2060],
i.e., at the device layer, network layer, service support and application support layer and the
application layer, whilst having some unique service requirements and capability requirements with
respect to other classes of services which are exploiting the capabilities of the IoT.
7.1.2 Support of data sharing
The data generated by EHM services can be shared among different EHM services according to
regulations, laws and other requirements.
7.1.3 Enhanced value via service support and application support layer capabilities
The service support and application support layer [ITU-T Y.2060] is key to the infrastructure of the
IoT. Based on the capabilities of the service support and application support layer, the capabilities
of the EHM services, e.g., data sharing and data communication, are enhanced in terms of
efficiency, reliability and safety.
7.1.4 Enhanced value via network layer capabilities
In order to support customer access to EHM services remotely and locally, the network acts as
a data transmission channel.
Based on the network layer capabilities, e.g., policy-based communication, network-based locating
and network resource provisioning, the capabilities of EHM services are enhanced, e.g., in terms of
network intelligence.
7.1.5 Combination of health-related technology and ICT
EHM services make use of both health monitoring-related technologies and information and
communication technologies (ICTs); this implies that EHM services have to comply not only with
ICT technical specifications but also with health-related specifications.
7.1.6 Multiple EHM devices serving one single user
Multiple EHM devices can serve one single user in a collaborative way.
Many EHM devices have a single function. For example, a blood pressure monitor measures blood
pressure but it does not collect other physical health signals, such as ECG information,
blood-oxygen levels, information on posture and so on. This implies that multiple EHM devices
may be associated with one single user in a collaborative way to gather health information.
7.1.7 Users with different accessibility needs
Since EHM services address people with different accessibility needs, they have to be capable of
meeting those needs accordingly.
7.1.8 Regulated services
Various EHM service aspects, including device, application and other aspects, are regulated by
specific entities according to regulation and laws. Different types of EHM services may need to
follow different regulation policies.
7.2 Specific characteristics of EHM services
7.2.1 Characteristics of EHM healthcare services
1) Service and network scalability
Compared to EHMT and EHMR services, the number of service providers and customers involved
with EHMH services may be very large, as there are less professional and administrative constraints
associated with these services. Consequently, service and network scalability is a key concern.
