Callout Response Data MDCs

The callout session information holds the results of a set of prerating queries for different events that happen at the same time, such as the following:

• When an IDP is received and a MAP callout is required to query location and MNP data.
• When an LDAP callout is required to retrieve subscriber information.

The callout session data is structured as follows:

MtxCallOutSessionInfoData {
    unsigned int32 LastResult
    unsigned int32 LastMapResult
    unsigned int32 LastMapErrorCode
    unsigned int32 AttemptCount
    MtxCallOutResponseData CallingCallOutResponse {...}
    MtxCallOutResponseData CalledCallOutResponse {...}
    MtxCallOutResponseData CallOutResponseList {...}
    unsigned int64 UsedActionProfileIdList
    }

In addition to the MtxCallOutResponseData MDCs, the combined results of the callout requests for the current message in the following top level fields are logged. This information is used to decide whether the callout successfully retrieves all the required information:

LastResult

LastResult is set for all types of callout request (both MAP and LDAP). It indicates the combined results of the single queries for this message:

• 0 — Success means that all the queries were successful.
• 1 — Fail means that one or more queries was unsuccessful.
• 2 — Timeout means that one or more queries timed out.
• 3 — Config error means that there is an error in the pricing file configuration for prerating queries. MATRIXX logs details of the configuration the error, such as the same prerating profile being selected more than once by the prerating profile generator for the same session message.

LastMapResult

The MAP protocol specific result for the last set of profiles processed, where:

• 0 — Success means that all the MAP queries were successful.
• 1 — Timeout means that the last MAP query timed out.
• 2 — Routing failure means that the last MAP query failed because a TCAP notice primitive was received indicating that the message was not sent to its destination.
• 3 — Error means that the last MAP query failed due to a ReturnError component received in response to the MAP operation.
• 4 — Aborted means that the last MAP query failed when a TCAP ABORT was received.
• 5 — Unexpected message means that the last MAP query failed when an unexpected message was received.
• 6 — System failure means that the last MAP query failed because there was an issue in the MATRIXX platform.

LastMapErrorCode

Set only for MAP callouts. If a ReturnError was received for the last MAP query, the error code is recorded in LastMapErrorCode. Otherwise, this field is not present.

AttemptCount

Set for all types of callout request (both MAP and LDAP). It records the number of callout attempts for this message. If the AttemptCount field is not present, it means that either the last time callouts were made for this message, they were all successful, or no callouts have been made.

When a new ApplyChargingReport message or a new Diameter accounting start or accounting interim message is received, these fields are removed from all the query logs and from the top-level fields.
