Types of Call Detail Records
Steel-Belted Radius Carrier can forward call detail records to a billing gateway when subscribers initiate and terminate sessions. Steel-Belted Radius Carrier can produce three types of CDRs:
Session CDRs—Generated at the end of each WLAN session. A session CDR records the length of time of the WLAN session and the number of bytes of data sent and received. Session CDRs can be generated during SIM authentication.
Partial CDRs—Generated periodically during a WLAN session either (a) after a specified amount of time has elapsed or (b) after a session has transferred a specified threshold quantity of data. A provider can specify how frequently a system generates a partial CDR by specifying time and volume (number of bytes) settings in the cdracct.acc file. After a partial CDR is generated for a subscriber session because a time or volume threshold is exceeded, both threshold triggers are reset to zero.
Partial CDRs can be generated during SIM authentication. A provider can configure time and volume thresholds for SIM authentication.
The Acct-Termination-Cause attribute reports the cause or reason for the subscriber session termination. For more information on the Acct-Termination-Cause codes and the corresponding termination causes, refer the Standard RADIUS Accounting Attributes section in the SBR Carrier Administration and Configuration Guide.
