The technical deployment for this scenario shown in Figure I.2 involves such entities as sensor,
handset, network, EHM application server, IoT platform and EHM database. Solid boxes represent
mandatory entities in this scenario. The dashed boxes represent an optional entity, and the dot dashed
boxes mean that the included entities can be integrated as an entity.

Figure I.2 – Mobile EHM services
1) EHM sensor
The EHM sensor can be seen as a type of EHM end point, which can sense EHM-related data
from the body of a user, but cannot access the communication network directly. There are
two methods for the deployment of a sensor. One is to deploy the EHM sensor inside the
handset, which can use the communication capability of the handset via an internal interface.
The other is to deploy the EHM sensor as a single device outside the handset. The sensor can
access the handset via a local communication protocol (e.g., Bluetooth or USB).
2) Handset
The handset is a type of communication terminal, which can access the communication
network via wireless communication. In the mobile EHM service deployment scenario, it can
play the role of communication gateway and provide the EHM data collected by the EHM
sensors to a remote EHM application server and IoT platform. Besides the communication
capability, the handset can also process and manage the EHM data collected by EHM sensors
or feedback from the EHM application server and IoT platform based on the EHM application
running on them and show the results to users.
3) Network
The network in the mobile EHM service deployment scenario is a type of communication
network, which can provide wireless access to the handset and also provide wired access to
the EHM application server and IoT platform. It supports interconnection among the handset,
EHM application server and IoT platform.
4) EHM application server
The EHM application server provides capabilities for analysing and managing the EHM data
provided by the handset or IoT platform and feeds the corresponding diagnosis results back
to the handset or IoT platform.
The IoT platform connects the handset with the EHM application server. It provides the
service support and application support capabilities for the handset and the EHM application
server. In practical deployment scenarios, multiple IoT platforms with different capability
sets may be deployed to form a virtual IoT platform.
5) EHM database
The EHM database is used for EHM data storage. Both the handset and EHM application
server can access the EHM database by authorization. There are three possible methods for
the deployment of the EHM database. The first consists of deploying the EHM database in
the IoT platform and opening secure access to the EHM database for the EHM application
server and the handset. The second consists of deploying the EHM database on the EHM
application server. The last is a hybrid method, consisting of deploying the EHM database
both in the IoT platform and the EHM application server.
