hi parsarka,

maybe you could conduct drive test to clarify this problem.
if from drive test you found that T200 timer is triggered after the HO, then you could try to tune the T200 FACCH/F or T200 FACCH/H timer...CMIIW
hope this help..

Thanks Nevy.i would try with the aforesaid parameters & let u know the results.Please suggest some more parameters from Huawei by which I can improve the TCH Drops other than RLT & SAACH multiframes.I tried with T3105,T8,MAX RETRANS OF PHYSICAL INFO but didnt see any major improvement.
