Hi experts,

After upgrade to RU30 we noticed an increase in the counter SETUP_FAIL_UE_HS_DSCH_INT in one RNC. :(

Has anyone experienced anything similar and did you find the root cause?

Thanks

Hi ,

In RU30 we have direct transition from cell_DCH to cell_PCH.
Some UEs can failed to move back from cell_PCH to cell_DCH based on TV_indicator in cell update message ( if TV is true ).
There are updates RN6.0.2.4 released few weeks ago which solves that issue.
Anyway I think that SW you have is old one and you should move o WN7.0.2.3/RN6.0.2.4. due to many other reasons :-)

Regards,
