3 daysenb: Fix non-1st ENB gnubreaker remote addressHEADmasterPau Espin Pedrol2-10/+14
ENB was using its own address as a remote address when the broker is used, which actually only holds true for the first ENB (since the broker is currently run on the same host/address of the first ENB). Change-Id: I5c83075d140632846c6d357152963754d16b4633
4 daysenb: Name preferrably by label, use it in remote run dirPau Espin Pedrol2-2/+3
This way several ENB will place its config and logs into different dirs. Change-Id: I9b0c74cd63bc3888f380c66d94271beafc0db915
5 daysCopy gnuradio zmq broker at runtimePau Espin Pedrol3-4/+27
The remotely run script is moved into a new subdir called "external", where external utils to be used by osmo-gsm-tester (exernal to its own process) are placed. It needs to be in another directory because python files in obj/ are loaded at startup of osmo-gsm-tester to dynamically load schemas. Change-Id: I633a85294694f2c6efd58535729e9b8af166b3ff
5 dayssysmocom: emergency_preemptive_call.py: Avoid test failure if 2nd call not ↵Pau Espin Pedrol2-13/+18
fully established It may happen that the non-emergency call MT leg is still not properly released when the emergency call MT leg is to be assigned a TCH, meaning BSC will fail with an Assignment Failure upon Assignment request from MSC. The test sometimes passed and sometimes didn't, due to above mentioned race condition. Let's relax a bit the test expectancies to have it always passing, while still verifying preemption happens, and MT phone is reached.

10 daysgnuradio zmq broker refactoringPau Espin Pedrol3-141/+172
First step towards support everal ENBs and installing the remote script at runtime: * The gnuradio broker class is moved to its own file, to decouple it from RFemu. * The ENBs are registered earlier in the test so that the GrBroker knows when to start (delay start + setup until all ENBs have been configured). * Handle ENBs internally as a list.

10 daysintra-freq-ho{-sameport}.conf: add scenarios for intra-freq HO cellsAndre Puschmann2-0/+32
we need to use two different configs for Amarisoft and srsENB. Amarisoft combines the two cells and transmits them on the same RF port, whereas srsENB sends them on a single port each. Change-Id: I3a2a8ae7bf4ed2dab6efba8550f442a741ad92e0

this scenario for 2xCA needs to have both cells on different EARFCN Change-Id: I3cd12da5453aa659839862775e23d4a308b92c8e
10 daysenb: add basic TDD config optionAndre Puschmann5-0/+49
this patch adds the basic notion of FDD and TDD duplexing modes to the eNB object. So far we've always assume FDD. Since only Amarisoft eNB supports TDD, the required config template changes, etc. are only applied there. The patch also adds a scenario to enable the default TDD config.

11 daysms: Allocate default msisdn internallyPau Espin Pedrol9-14/+15
Don't wait until adding it to the subscriber data base, since the msisdn may be needed beforehand (for instance in follow up patch to be passed to osmo-msc configuration to route emergency calls). Change-Id: I0d6902687e4beb3d6cdcefd4e343f21496100504
11 days4g: Introduce ZMQ GnuRadio stream brokerPau Espin Pedrol8-31/+515
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.

11 daysms: Fix and use ms msisdn() getterPau Espin Pedrol12-35/+35
The getter method was named the same as the itnernal field, and hence when used it would fail since the intenral field would be sleect and fail to be called. Change-Id: I2f631eb6256eb0e065f41d5b7531395c4a054cd8

12 daysenb-cells-2ca: fix config to match cell-id and cc idxAndre Puschmann1-14/+15

12 daystemplates/osmo-bts-trx: Increase osmo-trx rx-gainPau Espin Pedrol1-1/+1
Otherwise osmo-trx with a B200 seems to be having issues receiving some data from the MS otherwise, making "sms" test fail. In general LU works fine, and when MS sends the SMS, CM Service Request+Accept also works fine, but then the BTS never sees the CP-DATA afterwards probably due to MS power loop.

13 daysrfemu_srsenb_stdin: use negative dB value to set attenuationAndre Puschmann1-1/+1
the logic for the RF emulator on the command line is, like the Amarisoft equivalent, to set a negative gain value to express attenuation. Therefore, the sign needs to be inverted. Change-Id: I7b6ac611a9f711bbdc1570602bfd797a5346ab86

2020-10-12srsenb: Fix ECI in handover cell listPau Espin Pedrol1-1/+1
So far we only support setting cell IDs from same ENB. Support for handover to other ENB will come later, probably by adding some API to be called during the test to add own's CellID's to other ENB's config.t Change-Id: I1780bda130cde0faab15d4032117e0aa2b9c5dbe

2020-10-08jenkins-build-amarisoft: fix build script for ZMQ moduleAndre Puschmann1-0/+1
newer versions of srsLTE create symlinks with the rf library including the version, see below.
