enb: add measurement modifier to scenario files
this commit adds basic support for configuring measurements in the
eNB config. It currently support A1, A2, and A3 events.
By default UE measurements are turned off and need to be enabled by
configuring an event with:
+mod-enb-meas-event@{name},{report_type},{value},{hysterisis},{time to trigger}
For example one can update the a2 and a3 event with:
+mod-enb-meas-event@a2,rsrq,-40,2,480+mod-enb-meas-event@a3,rsrp,6,1,512

4g: Introduce ZMQ GnuRadio stream broker
srsENB currently creates 1 zmq stream (1 tx, 1 rx) for each cell (2 if
MIMO is enabled). Each cell transceives on a given EARFCN (and several
cells can transmit on same EARFCN).
However, for handover test purposes, we want to join all cells operating
on the same EARFCN to transceive on the same ZMQ conn, so that an srsUE
can interact with them at the same time (same as if the medium was shared).
Furthermore, we want to set different gains on each of those paths
before merging them in order to emulate RF conditions like handover.
In order to do so, a new element called the Broker is introduced, which
is placed in between ENBs and UEs ZMQ conenctions, multiplexing the
connections on the ENB side towards the UE side.
A separate process for the broker is run remotely (ENB run host) which
listens on a ctrl socket for commands. An internal Broker class is used
in osmo-gsm-tester to interact with the remote script, for instance to
configure the ports, start and stop the remote process, send commands to
it, etc.
On each ENB, when the rfemu "gnuradio_zmq" rfemu implementation is selected
in configuration, it will configure its zmq connections and the UE ones to
go over the Broker.
As a result, that means the UE zmq port configuration is expected to be
different than when no broker is in used, since there's the multiplexing
per EARFCN in between.
In this commit, only 1 ENB is supported, but multi-enb support is
planned in the future.
The handover test passes in the docker setup with this config:
"""
OSMO_GSM_TESTER_OPTS="-T -l dbg -s 4g:srsue-rftype@zmq+srsenb-rftype@zmq+" \
"mod-enb-nprb@6+mod-enb-ncells@2+mod-enb-cells-2ca+suite-4g@10,2+" \
"mod-enb-meas-enable -t =handover.py"
"""
and in resources.conf (or scenario), added:
"""
enb:
...
cell_list:
- dl_rfemu:
type: gnuradio_zmq
- dl_rfemu:
type: gnuradio_zmq
"""
Note that since the broker is used, there's not need for mod-srsue-ncarriers@2
since the broker is joining the 2 enb cells into 1 stream on the UE side.
