We were verifying LCSAP Location request message and found following
discrepancy in encoding/decoding of ECGI specifically in its PLMN Identity
part.
Following are the values that we passed to our application:
MCC = 120
MNC = 345
Hex value which was encoded and sent by our application for PLMNIdentity was:
215043.
This is s per specification ts_129274v100700p, see page number: 149. Section:
8.21.5 for ECGI:
------- -------
| MCC2 | MCC1 |
------- -------
| MNC3 | MCC3 |
------- -------
| MNC2 | MNC1 |
------- -------
However, value shown for MNC by wireshark is 534. See attached snapshot.
Can you please provide assistance on what is going wrong here?
