58  * radius_pdu.def - definitions of RADIUS Accounting PDU structure
59  *
60  * We implement a RADIUS accounting proxy to overcome the gap in the WAP
61  * stack that no MSISDN numbers are transported. Basically this is needed
62  * to map client IPs of the remote WAP/MMS clients to their MSISDN for various
63  * purposes. Ie. for WAP application a special HTTP header is added to identify
64  * the WAP client via it's MSISDN and to allow personalization of mobile content.
65  * For Kannel's MMSC we need mapping of client IP to MSISDN numbers to replace
66  * MMS "From:" header to the originator MSISDN.
67  *
68  * References:
69  * RFC2865 "Remote Authentication Dial In User Service (RADIUS)"
70  * RFC2866 "RADIUS Accounting"
