It looks like the SGSN is rejecting the ATTACH REQUEST. You may have a misconfiguration in the encryption config of osmo-sgsn? Unfortuantely, your pcap doesn't contain the contents of the Gb interface ("gprs-ns" filter in wireshark), so it's difficult to say what's going on. Please share a pcap containing gprs-ns (PCU<->SGSN) and gtp (SGSN<->GGSN) packets in order to find out what's going on. Share also a log file of osmo-sgsn (or use gsmtap log) with debug enabled to find out why is the SGSN rejecting it.

Could you solve this doubt? Can you please be specific? It implements the GGSN/P-GW side of GTP-U. GTP-U did not change from 2G to 3G to 4G to 5G. Your statement / claim is very broad and unspecific. Please outline which exact feature/functionality/procedure you would need and which is currently not supported? In any case, like all of Linux, and all of Osmocom, the GTP-U kernel module is a collaborative open source project. Anyone can submit contributions to extend its functionality and add whatever fetaure they may be missing. > This e-mail and the documents attached are confidential and intended solely for the addressee; it may also be privileged.
