As the customer is at 5th Floor or higher floor. You have to check the following things:-
1.Hardware issues
2.Multiserver(How many cells are serving that area and what are the frequencies of that.
3. It can be due to multiserver frequency interference.
4.it can be because of overshooting cells. either you have to downtilt or define handover.
