WRFD-181202 Uplink Data Acceleration (UDA) feature network impact - RAN19.1

Dears,

Here we're testing Uplink Data Acceleration feature where uplink PS data can be compressed before being sent (Ue-RNC). The results are Ok reducing by cell the time between RRC Connection Establishment and HSUPA RAB Establishment Completion. Nevertheless the signaling increased around 200% with high values of RRC Connection Release in CCCH by Normal Event (RRC.AttConnRelCCCH.Norm).

But according to the docummentation UDA feature starts working after RAB Setup and queries if the Ue support UDA after RRC Connection Setup, Have you test this feature before? Do you have any comments regarding the signaling impact.

Thanks in advance!

sorry didn't test this feature before,
have you found solution for signaling issue?
