PLMN and Time Zone Reporting
For some implementations of online charging, the OCS requires the PCEF to reporting location-specific subscriber
information. For certain subscriber types, subscriber information such as PLMN, Time Zone, and ULI can be sent over
the Gy interface as the subscriber changes location, time zone, and serving networks to provide accurate online charging
services. Such information can be reported independently from time and volume-based reporting.
PLMN and Time Zone Reporting feature is enabled to support location event reporting based on triggers from Gx, when
the following conditions are met:
Session-based Gy is not initiated due to the absence of charging-actions in rulebase with Credit-Control enabled
or due to delayed Gy session initiation.
PLMN and Time Zone Reporting feature is either enabled in the credit control group or through the use of
triggers received from Gx.
If session-based Gy initiation fails or the session goes offline due to configuration or network issues, event-based Gy
session will not be initiated.
Important:
Note that the failure-handling will not be supported for event-based Gy.
Though, in event-based Gy, multiple events can be reported independently and simultaneously this is presently not
supported. If an event occurs when the CCA-Event (CCA-E) of the previously reported event is awaited, then the new
event is queued and reported only when a CCA-E is received or the message is timed out.
To enable the PLMN and Time Zone Reporting feature, the PCRF shall send the Trigger AVP (Trigger Type 1, Trigger
Type 2) at the command level in a CCA.
The Event-based Gy session will be terminated in the following scenarios:
