Call drops increase after AMR with simultaneous HSDPA feature activation.

[rsv12]

Hi all,
Does anybody has experience with "AMR with simultaneous HSDPA" feature activation in NSN network? We see that some UE drop the AMR call when simultaneously HSDPA channel is allocated. There is now any AMR drops when the same UE is using Rel.99 PS channel. How it is look in others networks?

are the CE availability still enough for HSDPA and AMR working together(re check your HSDPA num user with existing CE and replanning if congest)

check direct retry and handover
