PING PONG H/O CAUSE AND SOLUTION

[Djemai]

CAN ANYBODY TELL ME THE PING PONG H/O CAUSE AND SOLUTION ?

the main causes are :
cross feeder, or unavailable cross connexion into the BTS

[mond86]

Solution:

Drivetest the area for possible overlapping of coverage, check where the HO was take place (Point of HO)
Delete unnecessary neighbors (Step by step)

Modify your HO offset (Step by Step)

Modify your Penalty Time (Increase) (step by Step)

If overlapping adjust your Cell Power first then drivetest again if it work revert your power and adjust now your antenna tilt (downtilt)

Note:Adjusting power might cause poor indoor penetration so it's not that recommended depending on the situation.

Consider if the area if highly populated and its terrain.. (Highly populated so to minimize drastic degradation of KPI) (Terrain so to be sure if its also affecting the handover to be consider on the penalty time modification.. to long penalty might cause drop call on a hilly area or poor quality due to to long cell Handover..
