3.2.22 PS Core Optimization

1) Brief descriptionThis task is to execute all PS core changing requests approved by operator, and to verifywhether the KPIs are improved after optimization. All the optimization solution approved by

operator will be executed in this task, such as system parameter optimization/ UMTS

multi-carrier optimization/ new feature introduction/ resource utilization optimizationetc.

2) Input

KPIs listed in Service Contract

Optimization proposals

Approved Changing request

3) Procedure

a) Execute PS core optimization.

b) Monitor the KPIs after solution was executed.

c) Compare the KPIs optimized and target (listed in contract), whether optimized KPIsreach the target.

d) If not, make further analysis.

9 SLASLA classification for radio network performance troubleshooting service is recommended asfollowing table.

Table 9-1SLA Classification

Category SLA

Availabletime

Responsetime

Restorationtime(Critical) /Remedy time(Major/Minor)

Resolution time

(without HW/SWproblem)

Critical 7*24 15 mins 2/4/6/8 hrs, 98% 2-10 days, 98%

Major 5*8 2 hrs 1-7 days, 98% 5-15 BDs, 95%

Minor 5*8 4 hrs 3-30 days, 98% 10-30 BDs, 95%

Note:

Traveling time and any delay caused by Huawei uncontrollable factor are excluded from the time

committed above.

Response times are only valid for service request tracked in MOS7100 or ITR or likely serviceworkflow management system.

For the definition of critical event, please refer to The Category of Radio Network Performance

Critical Event

For critical problems, restoration time is only valid when emergency recovery service is available,which is normally categorized into four class 2/4/6/8 corresponding specific recovering time.

The differentiation of major and minor category is defined by customer according to the emergencyof a problem.

BD refers to business day.
