Differentiated accounting in a packet data network
First Claim
1. A method for charging in a packet data system, the method comprising the steps of:
- a) initiating a packet data session between an IP-based terminal having assigned an MS IP address, and an IP-based Corresponding Node (CN) having assigned a CN IP address;
b) providing a Packet Data Access Node (PDAN) with CN'"'"'s related information including the CN IP address;
c) using the CN IP address of the CN, determining by the PDAN an amount of data exchanged by the CN with the MS during the packet data session; and
d) reporting the amount of data from the PDAN to an Authorization, Authentication, and Accounting server (AAA).

Abstract
A method, system and Packet Data Access Node (PDAN), such as a Packet Data Service Node (PDSN) of a CDMA2000 network, for performing accounting based not only on the IP address of a terminal associated with the PDAN (e.g. a Mobile Station), but also on information related to a Corresponding Node (CN) with which the terminal communicates over a packet data session, such as the CN IP address, and possibly the CN application ID or port number, and the Quality of Service (QoS) for that session. The session is established between the terminal and the CN using Session Initiation Protocol (SIP) signalling, and the PDAN is provided with the CN'"'"'s related information by a Proxy Call Switch Control Function (P-CSCF). The PDAN counts the traffic associated with the CN'"'"'s IP address, and reports that traffic, along with the CN'"'"'s information to an Authorization, Authentication, and Accounting server (AAA). Accounting can then be applied based on the CN'"'"'related information.

14. A packet data system comprising:
-
an IP-based terminal having assigned a terminal IP address;
an IP-based Corresponding Node (CN) having assigned a CN IP address;
a Packet Data Access Node (PDAN); and
an Authorization, Authentication, and Accounting server (AAA);
wherein when a packet data session is established between the IP-based terminal and the IP-based CN, the PDAN is provided with CN'"'"'s related information including the CN IP address and based on the CN IP address, the PDAN determines an amount of data exchanged by the CN with the MS during the packet data session, and reports the amount of data to the AAA server. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

- 27. A Packet Data Access Node (PDAN) acting to support a packet data session between an IP-based terminal having assigned a terminal IP address and an IP-based Corresponding Node (CN) having assigned a CN IP address, wherein when a packet data session is established between the IP-based terminal and the IP-based CN, the PDAN receives CN'"'"'s related information including the CN IP address and, based on the CN IP address, the PDAN determines an amount of data exchanged by the CN with the MS during the packet data session, and reports the amount of data to an Authorization, Authentication, and Accounting server (AAA).
