Test Manual
Pre-population of test data in DBAAS
In order to trigger the loop in the Traffic Steering use case, we must populate test data in DBAAS. This includes both cell and UE entries.
This is done through a script. Follow these directions to run the script:
git clone "https://gerrit.o-ran-sc.org/r/ric-app/ts"
cd ts/ts/test/populatedb
chmod a+x populate_db.sh
./populate_db.sh
This script will build a docker image locally and also install a helm chart in the kubernetes cluster to run the image.
The code that is run will write the necessary data to SDL
Onboarding and Deployment of xApps
The Use case involves three different xApps:
- Traffic Steering (TS) xApp
- QoE Prediction Driver (QPDriver) xApp
- QoE Prediction (QP) xApp
Each of them have a descriptor in their gerrit repo under the xapp-descriptor/ directory.
None of them have xapp specific controls and therefore no individual json schema
Here are the URLs for each which can be included in HTTP POST call to onboard tool
TS xApp:
QPDriver xApp:
QP xApp
Creation of Traffic Steering Policy Type and Policy Instance
TS xApp consumes an A1 Policy
Below are the steps for providing it with a policy.
Policy Type Create
Copy the following into a file called create.json -
{"name" : "tsapolicy", "description" : "tsa parameters", "policy_type_id" : 20008, "create_schema" : { "$schema" : "http://json-schema.org/draft-07/schema#", "type" : "object", "properties" : { "threshold" : { "type" : "integer", "default" : 0 } }, "additionalProperties" : false } }
Then run:
curl -X PUT --header "Content-Type: application/json" --data-raw @create.json http://<Base URL for Kong>/a1mediator/a1-p/policytypes/20008
Policy Create
Run command:
curl -X PUT --header "Content-Type: application/json" --data "{\"threshold\" : 5}" http://<Base URL for Kong>/a1mediator/a1-p/policytypes/20008/policies/tsapolicy145
