A1-PE-Simulator

A1-PE-Simulator (a1-pe-sim) is this is a Java SpringBoot application. This application contains docker image with shared docker volume to store the configuration.

Build package

Following mvn command in the current directory will build a1-pe-simulator package: mvn clean install

Artifacts

After build process described above, /target directory should contain:

• oran-sim-cba.zip - enriched CBA package for a1-pe-sim
• oran-sim-helm.tar.gz - helm chart for a1-pe-sim
• oran-sim-csar.zip - ONAP package with embedded the cba and helm chart for a1-pe-sim and can be used to onboard CNF to ONAP

Docker image

The a1-pe-sim is stored in dedicated repo: https://gerrit.onap.org/r/admin/repos/integration/usecases/A1-policy-enforcement-r-apps To create docker image pull and build this repository:

git clone "https://gerrit.onap.org/r/integration/simulators/A1-policy-enforcement-simulator"
cd A1-policy-enforcement-simulator
mvn clean install

After building you should find following docker image from local repository:

user@machine:~/A1-policy-enforcement-simulator$ docker images | grep sim
onap/integration/simulators/a1-pe-simulator     latest      171e5843928d        41 seconds ago      187MB

Run as docker

To run built docker images use docker-compose up -d in docker directory. You can stop it later with docker-compose down -v or without -v if you want to preserve shared volume (most likely, you don't).

Test A1-PE-Simulator

Manual test

Simulator part can be manually tested to be working e.g. by using curl request.

1. Get the configured cells (in configuration/cells.json):

curl --location --request GET 'http://localhost:9998/v1/ran/cells/'

Example response:

{
  "cells": [
    {
      "id": "Cell1",
      "latitude": 50.11,
      "longitude": 19.98,
      "connectedUserEquipments": [
        "emergency_samsung_s10_01"
      ],
      "currentState": {
        "value": "INACTIVE"
      }
    },
    {
      "id": "Cell2",
      "latitude": 50.06,
      "longitude": 20.03,
      "connectedUserEquipments": [],
      "currentState": {
        "value": "INACTIVE"
      }
    },
    {
      "id": "Cell3",
      "latitude": 50.06,
      "longitude": 19.94,
      "connectedUserEquipments": [
        "emergency_police_01",
        "mobile_samsung_s20_02"
      ],
      "currentState": {
        "value": "INACTIVE"
      }
    },
    {
      "id": "Cell4",
      "latitude": 50.11,
      "longitude": 19.88,
      "connectedUserEquipments": [],
      "currentState": {
        "value": "INACTIVE"
      }
    },
    {
      "id": "Cell5",
      "latitude": 50.01,
      "longitude": 19.99,
      "connectedUserEquipments": [],
      "currentState": {
        "value": "INACTIVE"
      }
    }
  ],
  "itemsLength": 5
}

2. Get the configured user equipments (in configuration/ue.json):

curl --location --request GET 'http://localhost:9998/v1/ran/ues/'

Example response:

{
  "ues": [
    {
      "id": "emergency_police_01",
      "latitude": 50.035,
      "longitude": 19.97,
      "cellId": "Cell3",
      "cellsInRange": [
          "Cell3",
          "Cell5"
      ]
    },
    {
      "id": "mobile_samsung_s20_02",
      "latitude": 50.05,
      "longitude": 19.95,
      "cellId": "Cell3",
      "cellsInRange": [
          "Cell3"
      ]
    },
    {
      "id": "emergency_samsung_s10_01",
      "latitude": 50.09,
      "longitude": 19.94,
      "cellId": "Cell1",
      "cellsInRange": [
        "Cell1",
        "Cell3",
        "Cell4"
      ]
    }
  ],
  "itemsLength": 3
}

3. Start sending events (based on the configuration in configuration/vnf.config directory). Also in vnf.config file, replace the vesHost=vesconsumer, vesPort=30417 with real values.

curl --location --request POST 'http://localhost:9998/v1/ran/cells/Cell1/start'

Success response:

VES Event sending started

Check A1-PE-Simulator container logs by executing command:

 docker exec -it a1-pe-simulator tail -f log/a1-pe-simulator/application/metrics-2021-04-28.0.log
