If you look at the attached capture (lcsap.snoop) you will notice the
following:
- In the id-E-UTRAN-Cell-Identifier IE the parameter E-CGI.pLMNidentity is
"decomposed" into MCC and MNC, but these two parameters are not displayed in a
way that it becomes clear it's only a decomposition (see attachment
"plmn.png"). I would expect that these two were displayed as collapsable items
"below" its "parent" pLMNidentity.

- The QoS parameters have no human-readable representation for
"horizontal-Accuracy: 19" and "vertical-Accuracy: 0". It would be very helpful
if a representation in "x.xxx m" was given.

- The IMSI parameter is not decoded, just the hex representation is given. It
would be nice if it could be displayed in a human-readable way (imsi.png).

Thanks very much in advance for looking into this. Please let me know if I can
in any way help.
