This is runs a complete core network with a virtual 2G BTS and two virtual 2G phones.
|
|
|
|
|
|
|
|
|
|
Steps:
|
|
|
|
|
|
|
|
|
|
- build osmocom-bb
|
2023-09-28 09:03:14 +00:00
|
|
|
git clone https://gerrit.osmocom.org/osmocom-bb
|
2022-08-28 23:44:12 +00:00
|
|
|
cd osmocom-bb/src
|
|
|
|
|
make nofirmware
|
|
|
|
|
cd ../..
|
|
|
|
|
Put programs virtphy and mobile in $PATH, e.g.
|
|
|
|
|
ln -s $PWD/osmocom-bb/src/host/virt_phy/src/virtphy ~/bin/
|
|
|
|
|
ln -s $PWD/osmocom-bb/src/host/layer23/src/mobile/mobile ~/bin/
|
|
|
|
|
|
|
|
|
|
- also have these programs available in $PATH:
|
|
|
|
|
- osmo-hlr
|
|
|
|
|
- osmo-msc
|
|
|
|
|
- osmo-mgw
|
|
|
|
|
- osmo-stp
|
|
|
|
|
- osmo-bsc
|
|
|
|
|
- osmo-bts-virtual (from osmo-bts)
|
|
|
|
|
- did i miss one?
|
|
|
|
|
|
|
|
|
|
- prepare HLR db; call this while no other osmo-hlr is running:
|
|
|
|
|
./create_hlr_subscribers.sh
|
|
|
|
|
|
|
|
|
|
- use run.sh to launch N terminals with one component each:
|
|
|
|
|
./run.sh
|
|
|
|
|
when you hit enter in this terminal, the entire network is torn down. (so continue in another terminal)
|
|
|
|
|
- of course you can instead launch the ten-odd components manually...
|
|
|
|
|
|
|
|
|
|
- Two virtual phones should subscribe to the network as soon as the two 'mobile' are launched.
|
|
|
|
|
Watch for 'bssap': "Location Updating Accept" with wireshark tracing 'lo'
|
|
|
|
|
|
|
|
|
|
- Launch (the signalling of) a voice call:
|
|
|
|
|
./call.sh
|
|
|
|
|
...
|
|
|
|
|
./hangup.sh
|
|
|
|
|
There will be no voice RTP stream, but the MGWs will be set up for it and the call will remain open.
