3.1 Definitions p. 9
For the purposes of the present document, the terms and definitions given in TR 21.905, TS 32.240 and the following apply:
Charging Data Record (CDR):
record generated by a network element for the purpose of billing a subscriber for the provided service. It includes fields identifying the user, the session and the network elements as well as information on the network resources and services used to support a subscriber session. In the traditional circuit domain, CDR has been used to denote "Call Detail Record", which is subsumed by "Charging Data Record" hereafter.
charging destination:
also referred to as a destination for charging, this is a nominal reference defining the point of termination of a connection for charging purposes
charging origin:
nominal reference defining the point of origin of a connection for charging purposes
I2 reference point:
3.2 Symbols p. 11
For the purposes of the present document, the following symbols apply:
A
Interface between an MSC and a BSC
Bc
Reference point for the CDR file transfer from the Circuit Switched CGF to the BD.
Gd
Interface between an SMS-GMSC and an SGSN, and between a SMS-IWMSC and an SGSN
Gs
Interface between an SGSN and an MSC/VLR.
I2
Interface between MSC Server enhanced for ICS and CSCF /ATCF
Iu
