It will download the necessary 3GPP YANG models and then produce a docker image with the name `nts-ng-o-ran-du-rel-18` and the version tag defined in the `.env` file, under the `NTS_BUILD_VERSION` environment variable. + +O-RU feature: monitoring NETCONF connectivity +--------------------------------------------- + +O-RAN.WG4.MP.0-R003-v11.00 defines, in chapter 6.7, a mechanism for monitoring the NETCONF connectivity to the O-RU. + +The simulated O-RU implements such a functionality: it listens for supervision-watchdog-reset RPC defined in the o-ran-supervision YANG model and reacts to it, replying with the time when the next supervision-notification will be sent. After the supervision-notification-interval has passed (default 60 seconds), the supervision-notification defined in the o-ran-supervision YANG model will be sent. The O-RU simulator waits then for another guard-time-overhead seconds (default 10 seconds) for receiving a new supervision-watchdog-reset RPC. If it is received, the mechanism starts again (either with the default values, or with the values that come inside the RPC). If not, a message is logged (`Failed to receive watchdog reset, terminating supervision timer for o-ran-supervision..`) and the mechanism stops sending any notifications. diff --git a/docs/release-notes.rst b/docs/release-notes.rst index 354caf1..8d2aa5e 100644 --- a/docs/release-notes.rst +++ b/docs/release-notes.rst @@ -63,6 +63,10 @@ The O1 interface simulator is a framework that provides simulated network functi Release Data ------------ +version 1.6.3 + +- [feature-add] new O-RU feature: monitoring NETCONF connectivity. + version 1.6.1 - [feature-add] new O-DU docker image containing 3GPP YANG models.
