Summary:

  • changes and optimizations for making NEF_emulator capable of running bigger scenarios
  • UE movement approach change:
    • old: iterate over all path-points and simulate speed by using sleep() (LOW=1sec HIGH=0.1sec)
    • new: constantly use sleep(1sec) and simulate speed by skipping (or not) path-points
    • more on the pros/cons of this approach can be found at the relative source code section, the old one is commented out
  • update of leaflet.js to version 1.8.0 (we've indetified a bug when closing mark tooltips, it's supposed to be fixed by the maintainers of the project at the upcoming release)

UI changes

  • dashboard-cells.js minor fix to display error details correctly in the toast message
  • 🪛 fix /map js console errors caused by the UEs layer-checkbox (access to null marker)
  • 🪛 fix /map UEs buttons: handle case of UEs with no paths assigned
  • /dashboard page change: instead of 2 consecutive API requests on UE Save 👇:
    • 1 API request to assign path everytime the user selects something different
    • 1 API request on Save button
  • /map page: add type-of-service column to datatable (cells now display Monitoring Event API or AsSession With QoS API)
  • /login: add "hit enter --> submit form" functionality
  • /register: add "hit enter --> submit form" functionality
  • add NEF logo
  • move part of login.js code to app.js (more clean approach + added app.default_redirect variable)
  • maps.js: increase timeouts to 60 sec (edge case with >200 UEs, start/stop takes time)
  • maps.js: add api_get_moving_UEs() to only retrieve moving UEs ➡ move part of ui_map_paint_UEs() to ui_map_paint_moving_UEs()
  • app.js: move api_test_token() outside document.ready() for quicker user auth checks
  • 401 page redirect: when the token can't be validated the user is redirected to a 401 Unauthorized page and after a few seconds is redirected to /login. Previously, the user was redirected to login without being notified.
  • map.js: optimize helper_check_path_is_already_painted( path_id ) by replacing the simple array of painted paths with a key-value object

Backend

  • ⛔ for optimization purposes, the UEs movement is handled in memory (no more intensive read/writes to Postgres) 👇
  • ➕ api/v1/ue_movement/state-ues now returns moving UEs information only. It helps with the edge cases of having many UEs and only a few of them actually moving around
  • create new module/file for threads utils.py ➡ ue_movement.py
    • ⛔ /utils/state-loop/{{supi}} ➡ /ue_movement/state-loop/{{supi}}
    • ⛔ /utils/start-loop ➡ /ue_movement/start-loop
    • ⛔ /utils/stop-loop ➡ /ue_movement/stop-loop
  • utils.py: add a 2nd approach for making the UEs move within their path and control their speed (see #2eb19f8)
  • SQLAlchemy: add pool_size=150, max_overflow=20 to create_engine( ... )
  • fix NoneType exception on MonitoringEvent one time request when cell is None
  • Add middleware to return custom response header X-Process-Time that counts request-response proccesing time
  • Split callbacks in two files 👉 From send_callback.py ➡ monitoring_callbacks.py + qos_callback.py
  • fix callback notification for QoS after the transition from db to memory

Database

  • postgreSQL add command: -c shared_buffers=256MB -c max_connections=200 to docker-compose
  • MonitoringEvent: migration from postgreSQL to MongoDB 👇
    • fix check_numberOfReports function accordingly

Libraries

  • upgrade leaflet.js (1.7.1 to 1.8.0)
