Enhanced Charging Service Overview  
▄ Cisco ASR 5000 Series Product Overview 
When a change of PDP context conditions (QoS change, SGSN change, PLMN Id change, RAT change) 
occurs a set of List of Service Data (LOSDV) and List of Traffic Volume (LOTV) containers, i.e. all active 
service data flow containers, will be added to eG-CDR.A maximum of 10 LOSDV containers are supported 
per eG-CDR.A maximum of 8 LOTV containers are supported per eG-CDR. 
When a change of tariff time occurs a set of List of Service Data (LOSDV) and List of Traffic Volume 
(LOTV) containers, i.e. all active service data flow containers, will be added to eG-CDR.A maximum of 10 
LOSDV containers are supported per eG-CDR.A maximum of 8 LOTV containers are supported per eG-
CDR. 
Failure handling 
procedure 
triggering 
When the failure handling mechanism is triggered and the failure action is set to ―continue‖ a set of List of 
Service Data (LOSDV) and List of Traffic Volume (LOTV) containers, i.e. all active service data flow 
containers, will be added to eG-CDR.A maximum of 10 LOSDV containers are supported per eG-CDR.A 
maximum of 8 LOTV containers are supported per eG-CDR. 
When an expiry of time limit, volume limit or termination is detected for a service data flow a set of List of 
Service Data (LOSDV) container is added to eG-CDR.A maximum of 10 LOSDV containers are supported 
per eG-CDR. 
When a CDR closure occurs all active List of Service Data (LOSDV) container is added to eG-CDR.A 
maximum of 10 LOSDV containers are supported per eG-CDR. 
 
 
Triggers to Close eG-CDRs 
The following table lists the trigger conditions to close the eG-CDR. 
Table 92.  Triggers for closing an eG-CDR 
End of PDP context in GGSN 
De-activation of the PDP context in the GGSN closes the eG-CDR. The trigger condition covers: 
  Termination of PDP context 
  Any abnormal release of PDP context 
eG-cDRs can be closed due to operation parameters and conditions.This trigger reason covers: 
  Data volume limit 
  Time duration limit 
  Maximum number of charging condition changes (QoS/tariff time change) 
  Management intervention 
  MS/Subscriber time zone change 
  Inter PLMN SGSN change 
  Radio Access Technology (RAT) change
