Figure 5 – Messages types for the BNG resource, events and status notifications

The message composition of RS-REQ, RS-RSP and A-RS-RSP is the same as clause 7.1.1, which is illustrated in
Figure 3.

7.3.2 Message format
7.3.2.1 Resource status request message

The resource status request message is defined as the RS-REQ message.
The RS-REQ message, indicated by the message type in the message header field, is sent by the service
platform to the BNG in order to get the resource status of the BNG.
Message format:
<RS-REQ-Message> ::= < Message Header >
{ Service-Platform-Id }
{ BNG-Id }
*{ Resource-Type-Id }
*[ Resource-Parameter-Id ]
*[ Auto-Resource-Type-Id ]
*[ Auto-Resource-Parameter-Id ]
Meanings and explanations:
1) Service-Platform-Id uniquely specifies the service platform;
2) BNG-Id uniquely specifies the BNG element;
3) Resource-Type-Id uniquely specifies the type of resources enquired by the service platform;

4) Resource-Parameter-Id is optional. Some of the resources may need this ID to specify the
intended resources. One possible example would be the port number (or ID) of the designated port;

5) Auto-Resource-Type-Id uniquely specifies the type of resources reported to the service
platform by BNG. Auto means the BNG will automatically report the specified resources to the
service platform in case of changes;
6) Auto-Resource-Parameter-Id is optional. Some of the resources may need this ID to specify
the intended resources. One possible example would be the port number (or ID) of the designated
port. Auto means the BNG will automatically report the specified resources to the service platform
in case of changes.

7.3.2.2 Resource status response message
The resource status response message is defined as the RS-RSP message.

The RS-RSP message, indicated by the message type in the message header field, is sent by the BNG to the
service platform in response to the RS-REQ message.
