Make sure Maven 3 or greater and JDK 17 are installed on your system.
Please ensure, that the prerequisites are fulfilled. To run a QoD API locally, you have to follow these steps:
- Build
- Create Database
- Start QoD API
Build the project by running mvn clean package
The creation of a Redis-Database is only needed if you use another profile than 'local'. Otherwise, QoD API will use an in-memory H2-database.
If a profile is used different to 'local', the QoD API needs a Redis database to persist the session data. Therefore, you can use a local instance of Redis DB or start Redis from Docker container:
- start Redis from Docker container by running
docker run --name qos-redis -p 6379:6379 -d redis - local instance on Windows: https://github.com/zkteco-home/redis-windows
- local instance on Linux: https://redis.io/docs/getting-started/installation/install-redis-on-linux/
For information about how to configure the QoD API, please refer to the next section "Configuration".
Start the qod-api service from terminal or from an IDE or with docker
- from
terminal:
java --add-opens=java.base/java.net=ALL-UNNAMED -Dfile.encoding=UTF-8 -jar core\target\senf-core-<current version>.jar --spring.profiles.active=local - from an IDE: Application can also be started directly from an IDE like IntelliJ, Eclipse, etc. by passing VM
options in the "Run Configuration":
- --add-opens=java.base/java.net=ALL-UNNAMED
- --spring.profiles.active=local
- with docker:
docker build -t qod-api .docker run -dp 9091:9091 -p 9092:9092 qod-api
With the 'local'-profile the application will automatically connect to an in-memory H2-database.
The configuration can be adapted here: core/src/main/resources/application.yml
The below table lists the environment variables that are used to configure the application properly. This reference implementation for the QoD API makes use of the AsSessionWithQoS API (https://www.3gpp.org/ftp/Specs/latest/Rel-17) which is usually made available as a part of a NEF/SCEF system. All variables in the below table starting with "SCEF" can be understood as NEF/SCEF.
| ENV | Description |
|---|---|
| SERVER_PORT | TCP/IP port listened on by application |
| MANAGEMENT_SERVER_PORT | TCP/IP port listened on by application management facilities |
| SCEF_SERVER_APIROOT | SCEF endpoint API root URL |
| SCEF_SERVER_SCSASID | ID of SCS or AS providing SCEF endpoint |
| SCEF_SERVER_SUPPORTEDFEATURES | A list of supported features used as described in subclause 5.8. (3GPP) |
| SCEF_AUTH_OAUTH_TOKEN | OAuth authentication token for calling SCEF endpoint |
| SCEF_NOTIFICATIONS_URL | URL for delivering (POST) notifications from SCEF, it should include the path /3gpp-as-session-with-qos/v1/notifications |
| QOD_QOS_REFERENCES | QoS reference for predefined specific QoS parameter set |
| SPRING_REDIS_HOST | Redis server host |
| SPRING_REDIS_PORT | Port where the Redis server is listening |
| EXPIRATION_TIME-BEFORE-HANDLING | How many seconds before expiration, should an ExpiredSessionTask be created |
| EXPIRATION_TRIGGER-INTERVAL | How often should the ExpiredSessionMonitor check for (almost) expired sessions |
| EXPIRATION_LOCK-TIME | How many seconds the session should be locked for the processing of the deletion task |
| MASK-SENSIBLE-DATA | If set to true, sensible data is masked in response body |
| ALLOW-MULTIPLE-UEADDR | If set to true, network segments are allowed for ueAddr |
The QoD reference implementation has been qualified against the following network service vendors:
| System Name | Vendor | Camara Testing Member | Qualified |
|---|---|---|---|
| 5G-NEF OpenLab | Nokia | DT | Yes |
| 5G-NEF | Ericsson | DT | Yes |
We actively ask other Camara members to validate this implementation against their available backend network services and share the results with the community.
