5. System Wise Monitoring and Alarm

a.

Success Rate of MME#3 shows problems.

b. AGEIS warns this to the operator c.

AEGIS Call Type Reason Analysis proposes ‘No Attach Complete’ cases are abnormally many

d. This occurred because of the packet loss inside MME

43


6. SIP Invite Burst a.

VoLTE setup failure increased with ‘No 100 Trying’

b. After further detail analysis through AEGIS Conditional Analysis, the problem was identified as the issue caused by certain group of subscribers.

7. TAS Problem Identify a. Individual Tracing

b. Realised only RTP Rx packet are exchanged and no Tx RTP packets are exchanged. c.

Rx RTP Packet NO!!! Tx RTP Packet

Normal VoLTE Call : ‘Allow’ field exist

Identified VoLTE Silent Call increase.

Further investigation proved the symptom occurs more frequently on a specific TAS (IP xx.xxx.xx.xx) .

d. Further detail packet analysis provided the answer that there is no ‘SIP – Allow’ field in case of silent call. Silent VoLTE Call : No ‘Allow’ field
