Create a Policy Type

Here we define a new policy type and call the A1 mediator to create such a policy type.

Run ...

$ cd ~/dep/
$ POLICY_TYPE_ID="20008"
$ echo '{ "name": "tsapolicy", "description": "tsa parameters", "policy_type_id": 20008, "create_schema": { "$schema": "http://json-schema.org/draft-07/schema#", "title": "TS Policy", "description": "TS policy type", "type": "object", "properties": { "threshold": { "type": "integer", "default": 0 } }, "additionalProperties": false } } ' > ts-policy-type-20008.json
$ curl -v -X PUT "http://$(hostname):32080/a1mediator/a1-p/policytypes/${POLICY_TYPE_ID}"   -H "accept: application/json" -H "Content-Type: application/json"   -d @./ts-policy-type-${POLICY_TYPE_ID}.json

List Policy Types

We now should see the newly created policy type when querying the A1 mediator.

Run ...

$ curl -X GET --header "Content-Type: application/json" --header "accept: application/json"   http://$(hostname):32080/a1mediator/a1-p/policytypes

Create a Policy Instance

Policy type is merely a declaration.  Now we create a policy instance, filling the properties with actual values.  This is also carried out by the A1 mediator. 

A1 mediator will distribute the new policy instance to the Traffic Steering xApp. 

And then we should see that the TS xApp receives this policy instancee and its behavior of "filtering RAN data by threshold" changing to using the new threshold value.

Run...

$ POLICY_ID="tsapolicy145"
$ curl -X PUT --header "Content-Type: application/json"   --data "{\"threshold\" : 5}"   http://$(hostname):32080/a1mediator/a1-p/policytypes/${POLICY_TYPE_ID}/policies/${POLICY_ID}
