Feature #5759: Support for Mobility between SGSN (2G/3G) and S-GW (4G)
test mobility between GERAN (OsmoPCU) and EUTRAN (Open5GS) end to end on real hardware
The mobility features that we recently added to Open5GS and OsmoPCU were developed and tested against TTCN3 testsuites, but we didn't confirm the functionality on real hardware yet.
To do this we need to create a setup with an OsmoBTS/OsmoPCU based GERAN cell and an appropriate EUTRAN ENB that is controlled by Open5GS. In order to be able to trigger the cell change it may be required to equip the transmittig antennas of both radios with variable attenuators.
