3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [50], TS 32.240 [1] and the following aply:
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: specified for use of call control protocol between MSC Server enhanced for ICS toward CSCF/ACTF, based on Mw reference point as defined in TS 23.002 [102] and the 3GPP profile of SIP as defined in accordance with TS 24.229 [220] and TS 23.292 [219].
3.2 Symbols
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 Interface between the RNS and the core network. It is also considered as a reference point
kbit/s Kilobits per second. 1 kbit/s = 210 bits per second.
Mbit/s Megabits per second. 1 Mbit/s = 220 bits per second.
Mc Interface between the MGW and (G)MSC server
R Reference point between a non-ISDN compatible TE and MT. Typically this reference point supports a standard serial interface.
Um Interface between the Mobile Station (MS) and the GSM fixed network part.
Uu Interface between the Mobile Station (MS) and the UMTS fixed network part.
