3 Unleashing the potential of the Internet of Things

The location provision capability supported in the SSAS layer includes:
1) Location information collection

The SSAS layer is required to collect the location information from the network layer
or device layer according to the collection strategy such as event triggered collection or
periodic collection.
2) Location information tracking

The SSAS layer is recommended to track the position of EHM customers via frequent
collection of the location information of EHM customers.
3) Location information reporting

The SSAS layer is required to report the location information required by the application
layer in standard format.

9.4 Capabilities of the network layer
9.4.1 Policy-based communication

According to service requirement 8.4.1(1), the network layer is required to provide policy-based
communication for EHM applications and EHM devices. Policy is a set of rules whose variables
include, but are not limited to, time, bandwidth, data throughput, network type, traffic priority,
and so on. By means of policy-based communication, EHM applications and EHM devices can
obtain the desired QoS.
The policy-based communication capability provided by the network layer is required to set the
network policy to support the QoS of EHM services according to their QoS requirements.

9.4.2 Network-based locating
According to service requirements 8.2.1(5), 8.2.2(5), 8.2.3(5), the network layer is recommended to
provide the location related information from the network layer (e.g., IP address, access point
location, and so on) for locating the position of EHM devices.
Event triggered location information notification is recommended to be supported. For example,
when the EHM customer has moved out of the preconfigured network area, a network location
information notification may be triggered by the event.
9.4.3 Network resource provision

According to service requirements 8.4.2(1), 8.4.2(2), 8.2.1(1), 8.2.2(1), 8.2.3(1), the network layer
is required to provide the network resource provision capability for EHM applications and EHM
devices. Example of network resources include, but are not limited to, a network address for an
EHM device, network bandwidth for an EHM application, and so on.
Depending on the specific deployment of EHM applications and EHM devices, EHM applications
and EHM devices may automatically use these provided network resources and configure
themselves to connect to the network directly. In this way, EHM customers can use the EHM
services directly, without the need to configure the EHM devices.

9.5 Capabilities of the device layer

9.5.1 Device identification
According to service requirement 8.4.1(1), the device layer is required to support device profiles to
identify the intended use of EHM devices, such as the supporting of EHMH and/or EHMR and/or
EHMT services.
