Background:
Brunei is covered with dense vegetation and has a large population, which results in great difficulty in radio coverage.
The investment is limited. The number of sites is insufficient. With poor coverage, the network also contains a great number of missing neighboring cells. The call drop rate ranges from 2% to 3%, which is quite high.
The operators in Brunei have little wireless network operation experience. They are also lack of operation and maintenance engineers.
After the Nastar is used:
The configuration of co-channel frequency neighboring cells is checked to one hundred percent. Therefore, the problem of missing neighboring cell configuration solved.
The problem of high call drop rate is solved while the coverage rate and coverage quality are ensured. All the KPIs reach the requirements.
The entire optimization requires three engineers working a day. Compared with the traditional optimization method, the efficiency is improved 20 times.

CSSR was decreasing and caused User-complaint to increase; but CSSR is good and stable after Nov.15 while user Complaints were still high and not affected.
CDR was decreasing but Call-Drop related Complaints was high and not affected. HQI is slightly increasing but voice Quality related user complaints was increasing.
Network KPI alone can not completely reflect the user experience, QoE monitoring and audit is necessary for the operator.

Background:
Brunei is covered with dense vegetation and has a large population, which results in great difficulty in radio coverage.
The investment is limited. The number of sites is insufficient. With poor coverage, the network also contains a great number of missing neighboring cells. The call drop rate ranges from 2% to 3%, which is quite high.
The operators in Brunei have little wireless network operation experience. They are also lack of operation and maintenance engineers.
After the Nastar is used:
The configuration of co-channel frequency neighboring cells is checked to one hundred percent. Therefore, the problem of missing neighboring cell configuration solved.
The problem of high call drop rate is solved while the coverage rate and coverage quality are ensured. All the KPIs reach the requirements.
The entire optimization requires three engineers working a day. Compared with the traditional optimization method, the efficiency is improved 20 times.
