8.3 Service requirements of an EHM device provider

The following EHM device provider requirements are essential for the support of EHM services.
1) In order to reduce EHM device costs and to provide support for interoperability with
service support platforms, EHM applications and other EHM devices, the EHM device
provider needs support for EHM devices which reuse common purpose capabilities as
much as possible.
2) When EHM device updates of software or firmware take place, the EHM device provider
needs support for notifying the EHM application provider and EHM customer.
3) The EHM device provider needs support for EHM device reliability and security according
to technical standards requirements.
4) The EHM device provider needs support for open interfaces to EHM device capabilities in
order to enable EHM device capabilities' access by EHM applications, service support
platforms, networks and other devices.

5) The EHM device provider needs support for the collection of fault information from
devices, networks, service support platforms and application to give verdict on whether the
root of an accident comes from the devices.
6) The EHM device provider needs support for acquiring the information related to device
initialization and registration from the application provider, platform provider and network
provider.
7) The EHM device provider needs support for the time calibration of EHM devices.

8.4 Service requirements of a network provider

8.4.1 Network provider essential requirements
The following network provider requirements are essential for the support of EHM services.

1) The network provider needs support for distinguishing which EHM service is in use
(i.e., EHMH, EHMR and EHMT). This is for example, to guarantee the EHM service's QoS
and EHM customer's QoE.

8.4.2 Network provider's essential but not EHM specific requirements

The following network provider requirements are essential for the support of EHM services but not
specific to EHM services.

1) The network provider needs support for providing access to EHM applications as fast as
possible upon service request.

2) The network provider needs support for obtaining the customer's EHM service-related
information in order to allocate or configure for the EHM customer the appropriate network
resources, such as IP address, network bandwidth, QoS policy, and so on.
3) The network provider needs support for flexible accounting for an EHM application
provider and EHM customer.
4) The network provider needs support for the collection of fault information from devices,
networks, service support platforms and applications to give verdict on whether the root of
an accident comes from the network.
5) The network provider needs support for the remote update of an EHM customer's network
subscription information residing in the EHM customer's device.
