Dear All,

I am Facing issue while on Iur For Speech Calls when E******* to ZTE Handovers Are happening Calls are getting Dropped. ZTE to E******* HO is OK.
RNC e******* is of 3810 P7 Version. All the External Cells are defined correctly. RNC is Under ATM Mode.

Please help As i am not able to Slve this issue from last 30 days.Even Iur Link all MO are up and Enabled. Please suggest If i need to check any paramter at RNC end.

Hi,

Core network Hard handover is activated? ( Check related parameters in RNC) also there is a internal parameter ( Just E/// team can see this parameters via their account) it is related to "relocation preparation time" you may increase this timer maybe.
