Proxy-MIP Call Setup using PAP Authentication
Step
Description
15
MS is not capable of CHAP authentication but PAP authentication, and the MS returns the EAP payload to indicate that it
needs EAP-GTC authentication.
16
PDIF then initiates EAP-GTC procedure, and requests a password from MS.
17
MS includes an authentication password in the EAP payload to PDIF.
18
Upon receipt of the password, PDIF sends a RADIUS Access Request which includes NAI in the User-Name attribute and
PAP-password.
19
Upon successful authentication, the AAA server returns a RADIUS Access Accept message, which may include Framed-
IP-Address attribute.
20
The attribute content in the Access Accept message is encoded as EAP payload with EAP success when PDIF sends the
IKE_AUTH Response to the MS.
21
The MS and PDIF now have a secure IPSec tunnel for communication.
22
Pdif sends an Accounting START message.
