Ron ron.menez at entropysolution.comHi Community, We tried to used the GPRS capability of OSMOCOM. Installation and configuration were based in the URL provided below: https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In_The_Box#OsmoBTS We successfully installed the needed elements to run GPRS and we were able to run the following: osmo-msc osmo-stp osmo-hnbgw (optional) osmo-ggsn osmo-sgsn osmo-mgw osmo-bsc osmo-trx-uhd osmo-hlr osmo-pcu UE were able to camp but IP Address is unavailable (checked it under Settings > About Phone > Status) No session / request coming in the OSMO-SGSN. We are also flooded with this log in OSMO-PCU: <000c> gprs_bssgp_pcu.cpp:848 Sending unblock on BVCI 1800 <000c> gprs_bssgp_bss.c:274 BSSGP (BVCI=1800) Tx BVC-BLOCK <000c> gprs_bssgp.c:288 Cell 001-01-23-0 CI 0 on BVCI 1800 <000c> gprs_bssgp_bss.c:294 BSSGP (BVCI=1800) Tx BVC-RESET CAUSE=O&M intervention <000c> gprs_bssgp.c:550 BSSGP BVCI=0 Rx BVC STATUS, cause=Protocol error - unspecified <000c> gprs_bssgp_pcu.cpp:354 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:304 Rx BSSGP BVCI=0 (SIGN) BVC_RESET_ACK <000c> gprs_bssgp_pcu.cpp:848 Sending unblock on BVCI 1800 <000c> gprs_bssgp_bss.c:274 BSSGP (BVCI=1800) Tx BVC-BLOCK <000c> gprs_bssgp.c:288 Cell 001-01-23-0 CI 0 on BVCI 1800 <000c> gprs_bssgp_bss.c:294 BSSGP (BVCI=1800) Tx BVC-RESET CAUSE=O&M intervention <000c> gprs_bssgp.c:550 BSSGP BVCI=0 Rx BVC STATUS, cause=Protocol error - unspecified <000c> gprs_bssgp_pcu.cpp:354 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:304 Rx BSSGP BVCI=0 (SIGN) BVC_RESET_ACK <000c> gprs_bssgp_pcu.cpp:848 Sending unblock on BVCI 1800 <000c> gprs_bssgp_bss.c:274 BSSGP (BVCI=1800) Tx BVC-BLOCK <000c> gprs_bssgp.c:288 Cell 001-01-23-0 CI 0 on BVCI 1800 <000c> gprs_bssgp_bss.c:294 BSSGP (BVCI=1800) Tx BVC-RESET CAUSE=O&M intervention <000c> gprs_bssgp.c:550 BSSGP BVCI=0 Rx BVC STATUS, cause=Protocol error - unspecified <000c> gprs_bssgp_pcu.cpp:354 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:304 Rx BSSGP BVCI=0 (SIGN) BVC_RESET_ACK Any suggestion / comments what seems to be the problem with our setup?
