### Wireshark not dissecting Geographic-location Type 138 and 139

Hi,

This is similar to my quesiton here : https://ask.wireshark.org/question/27981/radius-3gpp-user-location-info-bug-or-my-mistake/ I wasnt sure to post a new question or post it there, I decided to post a new question as it is not the same as my original question.

You can see in the screenshot that the type NG-RAN Node ID (138) is not dissected, and also the combined type with 5GSTAI(139). I assume it should be dissected since 5GS TAI type(136) does properly display TAC, MCC and MNC.

From my understanding NG-RAN Node ID should be displayed something like this:

20 -> number of bits in the ng-eNodeB bit string

length value = 18, short ng-eNodeB ID
length value = 20, ng-eNodeB ID
length value = 21, long ng-eNodeB ID
length value = 22-32, gNodeB ID


62 f2 20 -> MCC/MNC (MCC = 262, MNC = 02)

aa aa aa bb -> gNodeB ID
