TxGyRoCcrInitAnsGenPerErrCode

Measurement Group: OC-DRA Diameter Exception

Measurement Type: Simple

Measurement Dimension: Arrayed (by 3-digit error code defined in Policy DRA Error Resolution Procedures)

Description: The number of Gy/Ro Credit-Control-Request messages with the CC-Request-Type AVP set to INITIAL_REQUEST (CCR-I) that OC-DRA abandoned processing due to a failure and generated an Answer response.

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 INITIAL_REQUEST (CCR-I) 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

Measurement Scope: All

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 INITIATE_REQUEST (CCR-I) are being received and rejected due to the various reasons stated above for “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-I 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.
