Description

The Early IMS Authentication bases itself on network components asserting that IP addressing are and can only be used by authorized identities. In this case there is no need to challenge the REGISTER requests. However, it is often hard to distinguish between clients.

The CSCFs and HSS were modified accordingly to support these features. References: TS 33.978.

Updates

P/S-CSCF done since r180. Will close on validation with FHoSS

#2 submitted by flp on June 29, 2007 - 11:00

Fixed FHoSS Early-IMS Authentication - r360.
Fixed CSCF parsing Framed_IP_Address AVP for Early IMS - r358.

For using Early-IMS Authentication with OpenIMSCore change the registration_disable_early_ims in scscf.cfg as following :
modparam("scscf","registration_disable_early_ims",1)

Please keep in mind that the Authorization header in the REGISTER message must not be present.
