Customer test Ping from UE to server in their WCDMA network. They capture wireshark log in Iub. The question is, can they decode the "ping" in userplane? Please notice ciphering is on in the network.

Many thanks bmo

There's a big difference between decoding and deciphering. If you're referring to normal 'decoding' of IuB user-plane frames, I don't believe Wireshark can do it but some specialized analyzers can (eg: Tektronix).

Usually, it's way easier to capture it at the Iu interface after the RNC has done the decoding for you and put the packet into a simple GTP header.
