GPRS trafic in PCU - type BVC-UNBLOCK unknown // Protocol error - unspecified
Hi, I'm trying to run GPRS in my network. So far I get flooded with the bellow trafic in the PCU and the GGNS doesn't appear to receive any traffic. <000c> gprs_bssgp_bss.c:294 BSSGP (BVCI=2) Tx BVC-RESET CAUSE=O&M intervention <000c> gprs_bssgp.c:551 BSSGP BVCI=0 Rx BVC STATUS, cause=Protocol error - unspecified <000c> gprs_bssgp_pcu.cpp:348 Rx BSSGP BVCI=0 (SIGN) PDU type BVC-UNBLOCK unknown <000c> gprs_bssgp_util.c:238 BSSGP BVCI=0 Tx STATUS, cause=Protocol error - unspecified <000c> gprs_bssgp_pcu.cpp:298 Rx BSSGP BVCI=0 (SIGN) BVC_RESET_ACK <000c> gprs_bssgp_pcu.cpp:835 Sending unblock on BVCI 2 <000c> gprs_bssgp_bss.c:274 BSSGP (BVCI=2) Tx BVC-BLOCK <000c> gprs_bssgp.c:289 Cell 1-1-1-0 CI 0 on BVCI 2 Thanks, Filipe Laíns <https://github.com/FFY00> Sent via Migadu.com, world's easiest email hosting

Can you please explain your setup in more detail? What is "your network?" Which parts of it are Osmocom? Only the OsmoPCU side, or also OsmoSGSN? Also the GGSN side? If not, which implementations are used? A pcap format protocol trace of the related messages are helpful, as are the relevant config files.
