In Idle mode, for all sectors the following are checked:
o Each sector is serving with satisfactory level in its expected service area.
o Cell reselection from site to neighbors.
o Cell reselection from neighbors to site.
o Cell reselection between site sectors in a clockwise and anti-clockwise manner.
In Dedicated mode, for all sectors the following are checked:
o Each sector is serving with satisfactory quality in its expected service area.
o Cell handover from neighbors to site.
o Handover between site sectors in a clockwise and anti-clockwise manner.

2. Cluster Perform:
This test is mainly used to check network accessibility (Blocking) and retainability (quality).
To check Accessibility: Short Calls (Using sequence control) (EX: 30 (call duration) , 10 (duration between calls). Sequence
To check Retainability: Long call (Don’t forget ending the call before the hour and starting new Call).
Ex: Marina cluster
