Hi 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_I…
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:

Any suggestion / comments what seems to be the problem with our setup?
TIA.
