Hi,

we have case where call/HO re-establishment timer is setup till max. 32 seconds which is for DCR KPI givin perfect results, however this is far a way from customer perception where they are due to this fact having silent problem and releasing call on normal way. Specially there is more problem at 2G DCR than at 3G DCR. So question is what can be improved and changed in this case and what is normal/standard call re-establishment timer at network?

Call Reestablishment is normally disbaled in most network as in ours but its a fake method of improving Call drop!

hi kema i agree that call reestablishment is not so good a way to actually control the call drop. May be you should play with the parameter for call drop i.e keep the value of the parameter low say around 24 or 26 to avoid the silent problem and also improve the DCR . Hope you get it i was talking about Nokia paramter try finding something similar in Huawei. Rest i am really sorry if i may be wrong ;P
