Hello, friends,

As I met some problems when using Freeradius to send Disconnect Request.

Hope you can give me any suggestions.

Please let me describe my issue.

First I created a packete.txt for radclinet.exe.

The content of packet.txt is as:

Acct-Session-Id="00000001"

Calling-Station-Id="001E310008CC"

User-Name="wimax"

X-Ascend-Session-Svr-Key="0123456789"

NAS-IP-Address=100.1.6.5

NAS-Identifier=100.1.6.5

WiMAX-Session-ID=”XXXXXXX”

WiMAX-DM-Action-Code=”0000ffff”

After packet.txt was sent to AGW, radclinet debug window said: “Unknown WiMAX-Session –ID or Unknown WiMAX-DM-Action-Code ”

WiMAX NWG 1.3 says:

5.4.1.7 RADIUS Disconnect Request Message

isconnect Request message should be defined as per [28] with the following:

Attribute	TYPE	Description	DR	DR-ACK	DR-NAK
User-Name	1	The NAI of the MS as received during Access-Authentication.	1	0	0
Calling-Station-Id	31	The MAC address in binary format of the MS.	1	0	0
WiMAX-Session-ID	26/4	The NAI contained in the User-Name and the WiMAX-Session-ID forms a unique identifier of the session at the NAS.	1	0	0
WiMAX-DM-Action-Code	26/60	Carries the deregistration action code from AAA to the NAS.  If the WiMAX-DM-Action-Code is not present in the RADIUS Disconnect message then the result will be to the same as if the action code 0xffff was included.  The end result should be that the BS sends the RES-CMD to the MS.	0-1	0	0

So I must add and make WiMAX-Session-ID and WiMAX-DM-Action-Code sent by Freeradius.

Could you please give me any suggestions on how to add the attribute of WiMAX-Session-ID and WiMAX-DM-Action-Code into the sent message ?

Thanks a lot for your help in advance!
