The PDU session may need to be modified by various causes (see TS 29.502 [14]), whether a PDU session can be successful modified may impact the communication services supported by the PDU session. Therefore the performance of PDU session modification procedures need to be monitored. Besides PDU session modification requests and successes, the PDU session modification failures with specific causes need to be monitored for trouble shooting.
