Abstract

One embodiment is directed to an adapter entity comprising a Technical Report 069 (TR-069) protocol automatic configuration server (ACS) module configured to communicate with managed equipment included in a radio access network (RAN) using the TR-069 protocol. The adapter entity further comprises a Network Configuration Protocol (NETCONF) server configured to communicate with an Open Network Automation Platform (ONAP) Software Defined Network Radio instance (SDN-R) of an ONAP management and orchestration (MANO) environment using NETCONF. The adapter entity further comprises a TR-069-to-NETCONF mapper module, communicatively coupled to the TR-069 protocol ACS module and the NETCONF server, configured to dynamically map NETCONF requests and responses to and from TR-069 Protocol requests and responses. The adapter entity is configured to dynamically map NETCONF requests and responses to and from TR-069 Protocol requests and responses. Other embodiments and examples are disclosed.

First claim

What is claimed is:

1. An adapter entity configured to manage managed equipment included in a radio access network (RAN) comprising a plurality of nodes, at least some of which are communicatively coupled to each other via a fronthaul network, wherein the RAN is configured to wirelessly communicate with user equipment (UE), the adapter entity comprising:
a Technical Report 069 (TR-069) protocol automatic configuration server (ACS) module configured to communicate with at least one node of the RAN using a TR-069 protocol;
a Network Configuration Protocol (NETCONF) server configured to communicate with a management entity using NETCONF; and
A TR-069-to-NETCONF mapper module, communicatively coupled to the TR-069 protocol ACS module and the NETCONF server, configured to dynamically map NETCONF requests and responses to and from TR-069 Protocol requests and responses, wherein the NETCONF requests and responses are related to the managed equipment and are communicated between the NETCONF server and the management entity, and wherein the TR-069 Protocol requests and responses are related to the managed equipment and are communicated between the TR-069 protocol ACS module and the managed equipment.

2. The adapter entity of claim 1 , wherein the management entity comprises an Open Network Automation Platform (ONAP) Software Defined Network Radio instance (SDN-R) of an ONAP management and orchestration (MANO) environment.

3. The adapter entity of claim 2 , wherein the ONAP MANO environment is configured to be deployed in an environment that uses a Kubernetes cluster; and
wherein the adapter entity is implemented as a Kubernetes pod or container for deployment in the Kubernetes cluster.

4. The adapter entity of claim 1 , wherein the managed equipment comprises a baseband unit of a radio access network.

5. The adapter entity of claim 1 , wherein the managed equipment comprises multiple nodes of the RAN, wherein the ACS modules are configured to communicate with said multiple nodes of the RAN using the TR-069 protocol.

6. The adapter entity of claim 1 , where the adapter entity is configured to:
receive a TR-069 INFORM remote procedure call (RPC) sent from the managed equipment that specifies a particular event associated with the managed equipment has occurred;
determine which, if any, TR-069 RPCs need to be issued to the managed equipment in response to the received TR-069 INFORM RPC;
determine which, if any, messages need to be sent to one or more entities in the ONAP MANO environment in response to the received TR-069 INFORM RPC;
issue to the managed equipment any TR-069 RPCs that need to be issued in response to the received TR-069 INFORM RPC;
receive respective responses to the TR-069 RPCs; and
send any necessary messages to be sent to one or more entities in the ONAP MANO environment response to the received TR-069 INFORM RPC.

7. The adapter entity of claim 6 , wherein the TR-069 INFORM RPC specifies that one of the following events has occurred at the managed equipment: a BOOTSTRAP event, a BOOT event, an ALARM VALUE CHANGE event, a PERIODIC event, a CONNECTION REQUEST event, a TRANSFER COMPLETE event, and an AUTONOMOUS TRANSFER COMPLETE event.

8. The adapter entity of claim 6 , wherein the TR-069 INFORM RPC includes a Device Identifier (DeviceID) tag.

9. The adapter entity of claim 8 , wherein the DeviceID tag comprises a serial number assigned to the managed equipment.

10. The adapter entity of claim 6 , wherein the TR-069 protocol ACS module is configured to receive the TR-069 INFORM RPC sent from the managed equipment.

11. The adapter entity of claim 6 , wherein the TR-069-to-NETCONF mapper module is configured to determine the TR-069 RPCs, if any, that need to be issued to the managed equipment in response to the received TR-069 INFORM RPC and to cause the TR-069 protocol ACS module to issue to the managed equipment any TR-069 RPCs that need to be issued in response to the received TR-069 INFORM RPC.

12. The adapter entity of claim 6 , wherein the TR-069 protocol ACS module is configured to receive the respective responses to the TR-069 RPCs.

13. The adapter entity of claim 1 , wherein the adapter entity further comprises a VNF Event Streaming (VES) Notifier module;
wherein the TR-069-to-NETCONF mapper module is configured to push, to the VES Notifier, data from the received TR-069 INFORM RPC and/or from one or more of the responses to any of the TR-069 RPCs issued to the managed equipment; and
wherein the VES Notifier is configured to validate, filter, and package the pushed data and communicate the packaged data to a VES Collector function included in the ONAP MANO environment.

14. The adapter entity of claim 1 , where the adapter entity is configured to:
receive one more NETCONF remote procedure calls (RPCs) sent from the management entity, the received NETCONF RPCs specifying one or more NETCONF operations to performed for the managed equipment;
determine one or more TR-069 RPCs to issue to the managed equipment in order to carry out the one or more NETCONF operations specified in the one or more received NETCONF RPCs;
issue the determined one or more TR-069 RPCs to the managed equipment in order to carry out the one or more NETCONF operations specified in the one or more received NETCONF RPCs;
receive respective responses to the TR-069 RPCs;
