I share the pcap file from communication, IP address of BSS is 74.33.6.1 and IP address of osmo-sgsn is 74.33.9.1...The first problem was, that sgsn didn´t create funcional NS-VC but after a configuration from vty this was solved, but NS-VC seems to become  blocked after BVC-reset message from bss....I can not share binary files of sim-bss cause it is out of my possibilities...

can you provide access to that BSS simulator. Have you taken a packet
trace and looked at what the system actually sent? Please share a PCAP
file.
