Problem and Analysis

Poor coverage due to no handover later resulted to dropped call.


13/24

Poor coverage due to no handover between B6002_3 M(1800) & B6002_1 later

resulted to dropped call before cell reselection took place. B6002_3 M(1800) dragged

the call without handed over to B6002_1 that has much better signal within its

coverage area. The signal of B6002_1 was much better till the call dropped. This

could be due to handover parameter settings.

Problem and Recommendation:

Problem:

Recommendation:

Handover parameter setting should be checked and modified to solve this problem.


14/24

Problem and Analysis:

Interference on B6447_3 M(1800).


15/24


Problem:

Recommendation:

There is persistent interfence on B6447_3 M(1800)

Frequency, hardware and cable connections should be checked.


16/24


Handover failures between B6001_3 M1800 and B6002_1 M900.


17/24


Problem:

Recommendation:

There is handover failures between B6001_3 M1800 and B6002_1 M900).

Check hardware, handover parameters setting and congestion on target cell.


18/24


Interference on B6457_1


19/24


Problem:

Recommendation:

There is serious interference on B6457_1

Frequency, hardware and cable connections should be checked.


20/24


Handover failures between B6011_1 & B6011_2 M(1800 & 900).


21/24


Problem:

Recommendation:

There is handover failures between B6011_1 M1800 and B6011_2 M900). Handovers

fails repeatedly on B6011_2 whenever handover was initiated between B6011_1 M(1800) &

B6011_2. It also fails between B6011_2 and other neighbour cells.

Check hardware, handover parameters setting and congestion on target cell. B6011_2

neighbour definition should be checked ASAP.


22/24


Call dropped due to Abnormal network
