Manual Testing With osmo-dev
With osmo-dev it is possible to build all Osmocom components for a full test network with OsmoBSCNAT, and run the network on your PC. Set up the make directory as described in osmo-dev's README, then build components with:
$ make cn-bsc-nat
Set up a network as described in osmo-dev's net/README, then put the following in your configuration to let it run osmo-bsc-nat with one virtual BSC, BTS and MS (can be used next to a real BSC/BTS/MS):
BSC_COUNT=2 BTS1_RUN_IN_OSMO_DEV=1 STP_RAN_IP="127.0.0.2" MS_RUN_IN_OSMO_DEV=1
