Sample OTMA message flows
The following topics show some sample message flows, and describe how various fields in the message prefix are set.
In the figures, the following abbreviations are used for
parts of the message prefix:
- MC
- Message-control information section
- SD
- State-data section
- SE
- Security-data section
- US
- User-data section
- AP
- Application-data section
The sample flow diagrams show which parts of the prefix are mandatory for a given message and which are not applicable. Optional fields and prefix sections are enclosed in parentheses.
For
transactions submitted by clients, the following principles apply:
- After IMS sends an ACK message to a client, IMS sends a commit confirmation (indicating that the transaction committed successfully or was aborted).
- The commit confirmation terminates a client transaction.
