[c-nsp] OT: IMA Based Authentication Vs PPPoE

[Cisco Boy]

Hi Guys,
I am sorry for very off topics.
The application is BWA (WiMAX).

Just wondering if someone has implemented the IMA based billing solution.
I am looking for authenticating the unique ID of the WiMAX CPE's (IMA#) 
based billing. Once the CPE is authenticated all in/out traffic from 
that perticular IMA# will be billed to the customer. But I am not sure 
how actually it integrates with AAA server? Is there an special AAA 
server in the market which does this or all Radius server can do this 
sort of clever things?

I found it very intresting compared to PPPoE tunnel. The advantage over 
PPPoE is , user don't have to create the PPPoE connection to authenticate.


Your input much appreciated.
