GGSN: real APN selection using Radius

We are trying to setup the virtual APN with "pre-authentication" feature on GGSN Release 9, whereas the Radius server changes the APN during the authentication stage.

The question is which Radius attribute in the Access-Accept should contain the new APN, as the documentation is too generic:

"The target APN is returned as a Radius attribute in the Access-Accept message to the GGSN".

We have tried to use "Called-station-ID" which is the attribute that carries the incoming APN (virtual APN).

Thanks
