Hi, I am working on adding a 3GPP Cell Identity tag to the exported_pdu header. A single-octet type field precedes the actual value and specifies if the identity is the CGI, ECGI, or NCGI.
I have a question about the PLMN component at the beginning of each global identity field. There are several ways to encode it. In our application, we chose the one described in [3GPP TS 36.455] (paragraph 9.2.6, ECGI; paragraph 9.2.26, NR CGI). Is it ok if I define the exported_pdu header following 3GPP Information Element encoding? The Selected PLMN identity consists of 3 digits from MCC followed by either a filler digit plus 2 digits from MNC (in case of a 2-digit MNC) or 3 digits from MNC (in case of a 3-digit MNC). [0] MCC digit 2, MCC digit 1 [1] MNC digit 1, MCC digit 3 [2] MNC digit 3, MNC digit 2 Examples: MCC: 321 MNC: 987 PLMN: [0] 0x21, [1] 0x73, [2] 0x98 MCC: 321 MNC: 98 PLMN: [0] 0x21, [1] 0xF3, [2] 0x98 Regards, Mauro [3GPP TS 36.455] https://www.etsi.org/deliver/etsi_ts/136400_136499/136455/16.01.00_60/ts_136455v160100p.pdf ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
