Collection Interval

5 min

Peg Condition

Each time OC-DRA abandons the processing of a Gy/Ro Credit-Control-Request message with the CC-Request-Type AVP set to UPDATE_REQUEST (CCR-U) due to a failure and generates an Answer response. Processing failures include the following:

• OC-DRA is Unavailable or Disabled
• Diameter Protocol Error Detected
• OC-DRA specific errors due to absence of mandatory Diameter Credit Control Application AVP(s) used for routing
• Diameter Message Routing failure due to DRL's Request Queue Full
• Communication Agent Error (i.e., Queue Full)
• Unexpected SBR Error
• Online Charging Session not found when required for routing

Recovery

1. This measurement represents an exception condition in which Gy/Ro Diameter Credit-Control-Request messages with the CC-Request-Type AVP set to UPDATE_REQUEST (CCR-U) are being received and rejected due to the various reasons stated in “Peg Condition”. A Diameter Answer response including an Error-Message AVP is generated for each Diameter Request message that is rejected.
2. This measurement shows the distribution of Gy/Ro Diameter CCR-U messages that OC-DRA generated a Diameter Answer with error response across the range of 3-digit error codes defined in Policy DRA Error Resolution Procedures to determine the specific cause of failure and resolution using the 3-digit error codes.
