Multi-RAB Problem

[yilkork]

Hi experts,
I faced a problem while i'm using a smartphone.
I made a voice call and i tried to made data connection during Voice call and th smartphoen says "a Voice Call is still continue. You can't browse until the voice call is ended".
Is there any limitation or problem on Multi-RAB functionality on 3G (making data during voice call).

P.S. : Vendor is Huawei


Many Thanks

firstly check this out :

1. MULTIRAB already activate on your RNC system? see some feature/licence (our NSN network already ON in RU20)

2. UE support type (some smartphone looks like not supported MULTIRAB), what type of your UE (type 2 and 3 not supported)

3. SGSN feature, our NSN SGSN already upgrade that support this function

Hi adewijaya,
Multirab is already activated on our RNCs because non-smart phones(Sony-E******* W995i) can make multirab. We tried multirab with blackberry bold 9000 and iPhone 4 and they couldn't make multirab.
I didn't check the SGSN side.

No any problem for NSN in RU20 when Iphone4 used. If still have proiblem that shodu be UE side, not the equitment, please change other UE and try again.
