GSM: Channel Release
Hello Sir,
I found that wireshark is not able to decode below RAW data correctly. Problem is with "Cell Selection Indicator after Release of all TCH and SDCCH IE --> E-UTRAN Description struct" decoding
RAW data: 06 0d 00 73 04 01 00 00 00 c1 77 1b 70 51 4d 84 38 1a e1 94 0c d8 65 34 b6 19 60 0d 86 5a 43 61 98 26 d8 67 fa 36 00
Actual EARFCN list is below: 1300/3590/37900/38098/38400/38544/38950/40936
But decode is only 2 EARFCN: 1300 and 19297
It decodes
Cell Selection Indicator after Release of all TCH and SDCCH
Element ID: 0x77
Length: 27
E-UTRAN Description
...1 .... = Repeating E-UTRAN Description struct: Present
.... 0000 0101 0001 0100 .... = EARFCN: 1300
.... 1... = Measurement Bandwidth: Present
.... .101 = Measurement Bandwidth: NRB = 100 (5)
1... .... = Repeated E-UTRAN Not Allowed Cells: Present
E-UTRAN Not Allowed Cells
.0.. .... = Repeated PCID: Not Present
..0. .... = PCID Bitmap Group: Not Present
...0 .... = PCID Pattern: Not Present
.... 0... = Repeated E-UTRAN Frequency Index: Not Present <-- This must be 0 | 1 < TARGET_PCID : bit (9) > };
.... .1.. = Repeated E-UTRAN Not Allowed Cells: Present <-- { 1 <E-UTRAN Description : < E-UTRAN Description struct >> } ** 0 };
