It's actually easier than all that. I assume you need to send back to the NAS a particular string in order to provision the CPE to a particular service flow or set of service flows. Simply use a reply or group reply attribute. Most WiMax base stations can read Framed-Filter-ID or Filter-ID="service_flow_attrribute_here" if you send it in your authentication reply.

I am now using a WiMAX network and I want to use freeradius+mysql (and EAP, TLS) for it. Now I need to add some new attribute (such as the service level for a single client) in the mysql database. And then the freeradius server can return the attribute to tell the AGW. I have looked up some methods on the Internet and I found these pages: http://ubuntuforums.org/showthread.php?t=151781 http://www.frontios.com/freeradius.html
From the above two links, I have a basic idea. I think I can create a new table in the databse to store the new attribute like this: user1 attribute-value-user1 user1 attribute-value-user2 ....
Then as stated in http://www.frontios.com/freeradius.html, the rlm_sql is responsible for return some pre-defined attributes to the AGW and SS. Then I write some code in rlm_wimax.c to query the database for the new defined attribute and return it to the AGW to let it know. I don't know it is right? Or otherwise I should write my db operation code in rlm_sql? Thanks a lot for your kindly help!
