Hi Yinxing,

After reading the draft, I have a doubt concerning with your proposal. In section 4, step 3, the text says:

When RP receieves the request from UE, it checkes whether the
       credential is avialable.  If not, RP initiates AAA request to
       retrieve credential from IdP [I-D.ietf-abfab-aaa-saml]
       [I-D.jones-diameter-abfab].

It is not clear to me how credentials (MSK or similar) are transported to the RP, since it seems (due to the references you cite) that it is done through SAML.
Can you provide further details on this, please?

Regards,
Alejandro

Title:                                   Federated Cross-Layer Access
Creation date:                  2011-10-31

Abstract:
Network stratum and application stratum form a federation to
  faciliate user's access.  Network operator acts as Identity Provider
  (IdP), and application reuses underlying network's security
  capabilities to simlify application's access.  This document is to
  introduce such federated cross-layer access use case and message
  flows.
