5 Unleashing the potential of the Internet of Things

In the EHM application server, the EHM capabilities are distributed in a network layer, service
support and application support layer, application layer, as well as cross-layer EHM management and
security capabilities.

Clauses 8.2 to 8.7 provide details of this distribution map.

Annex A provides an overview of EHM capabilities, summarizing their distribution in the different
EHM components.

8.2 Application layer capabilities of EHM components

8.2.1 Information sharing

According to the capability requirements described in clause 9.2.1 of [ITU-T Y.2065], the application
layer of the components is recommended for support of standard interfaces and policy-based
mechanisms [ITU-T Y.2065] to enable the sharing of EHM information among EHM components.

Table 1 shows the EHM components involved in the information sharing capability of application
layer: the first column indicates the EHM components providing the EHM information, the first row
indicates the EHM components receiving the EHM information.

8.2.2 Accounting-related information provision
According to the capability requirements described in clause 9.2.2 of [ITU-T Y.2065], some EHM
components are recommended for provision of the capability for accounting-related information
provision.
The specific requirements of the accounting-related information provision capability of application
layer for each EHM component are described in Table 2.
