Why We Need FM System ?
11
Limited of
Human Resource
12
Various NE Vendors in The Same Network Environment
Radio Sub System Core Sub System VAS-Billing Sub System
13
1G 2G 3G Technology & Network are More Complex
14
We Have Huge
Number of Alarms from
Huge Number of Network Elements
15
Need to Find The Root
Cause and Solve the Problems
Faster
16
As a Part of The Service
Oriented OSS Puzzle
17
Complete It With Integration
Fault M anagement

Sample of Use Case
20
FM System (2. collect, and correlate the alarms,
find the root causes of the problems)
1. Alarms that indicate a
problem.
problem problem
Trouble Ticketing Management System
3. Open a trouble
ticket
4. Assign the ticket to the
related Engineer
5. The Engineer solve
the related problem in the network
elements by using the root cause
information from the FM system.
6. Problem solved, the NE send clearance
alarm to the FM system.
7. FM system send information to TT
Management to close the ticket.
8. Notify the Engineer that the ticket
is closed.
Knowledge Management System
9. TTM log the
problem information to
KMS
10. The engineer insert the
way how he solve the problem in the KMS
