Abstract

A method for managing configuration information is disclosed including: an operation support system (OSS)/network management system/(NMS) receiving a lifecycle operation completion message of a virtualized network function (VNF); and sending a management information object instance operation request message corresponding to a lifecycle operation of the VNF to an element management system (EMS) according to the received lifecycle operation completion message of the VNF. A method and device for managing configuration information, an element management system (EMS) and a storage medium are also disclosed.

First claim

I claim:

1. A method for managing configuration information, the method comprising:
receiving, by an operation support system/network management system (OSS/NMS), a lifecycle operation completion message of a virtualized network function (VNF); and
sending a management information object instance operation request message corresponding to a lifecycle operation of the VNF to an element management system (EMS) according to the received lifecycle operation completion message of the VNF.

2. The method for managing the configuration information according to claim 1 , wherein a parameter carried in the request message comprises a distinguish name (DN) of the management information object instance corresponding to a VNF instance.

3. The method for managing the configuration information according to claim 1 , wherein:
when the lifecycle operation completion message of the VNF is a confirmation message, sent by a NFV orchestrator (NFVO), for Instantiate VNF completion, the management information object instance operation request message corresponding to the lifecycle operation of the VNF is a request message for creation of the management information object instance corresponding to the VNF instance;
when the lifecycle operation completion message of the VNF is a notification message, sent by the EMS, for Instantiate VNF completion, a parameter carried in the notification message comprises an Identity (ID) of the VNF instance and a VNF instance type, and the management information object instance operation request message corresponding to the lifecycle operation of the VNF is a request message for creation of the management information object instance corresponding to the VNF instance;
when the lifecycle operation completion message of the VNF is a confirmation message, sent by the NFVO, for Terminate VNF instance completion, the management information object instance operation request message corresponding to the lifecycle operation of the VNF is a request message for deletion of the management information object instance corresponding to the VNF instance;
when the lifecycle operation completion message of the VNF is a confirmation message, sent by the NFVO, for VNF instance alteration completion, if it is determined that the management information object instance is required to be updated, the management information object instance operation request message corresponding to the lifestyle operation of the VNF is a request message for updating of the management information object instance corresponding to the VNF instance; and
when the lifecycle operation completion message of the VNF is a notification message, sent by the EMS, for VNF instance alteration completion, a parameter carried in the notification message comprises the ID of the VNF instance and a VNF instance alteration operation type, and if it is determined that the management information object instance is required to be updated, the management information object instance operation request message corresponding to the lifecycle operation of the VNF is a request message for updating of the management information object instance corresponding to the VNF instance.

4. A method for managing configuration information, the method comprising:
receiving, by an element management system (EMS), a lifecycle operation completion message of a virtualized network function (VNF) or a management information object instance operation request message; and
operating a management information object instance according to the received message, and operating a mapping relationship between the management information object instance and a VNF instance.

5. The method for managing the configuration information according to claim 4 , wherein an attribute of the mapping relationship between the management information object instance and the VNF instance comprises a distinguish name (DN) of the management information object instance corresponding to the VNF instance and an Identity (ID) of the VNF instance.

6. The method for managing the configuration information according to claim 4 , wherein;
when the management information object instance operation request message is a request message, sent by an operation support system/network management system (OSS/NMS), for creation of the management information object instance corresponding to the VNF instance, and a parameter carried in the request message comprises the DN of the management information object instance and the ID of the VNF instance, operating the management information object instance and operating the mapping relationship between the management information object instance and the VNF instance comprises: creating the management information object instance, and creating the mapping relationship between the management information object instance and the VNF instance;
when the management information object instance operation request message is the request message, sent by the OSS/NMS, for creation of the management information object instance, and the request message carries a parameter indicating triggering of Instantiate VNF, operating the management information object instance and operating the mapping relationship between the management information object instance and the VNF instance comprises:
sending an Instantiate VNF request message to the VNFM according to the request message,
receiving the confirmation message, sent by the VNFM, for Instantiate VNF completion; and
creating the management information object instance, and creating the mapping relationship between the management information object instance and the VNF instance;

when the management information object instance operation request message is the notification or confirmation message, sent by the VNFM, for Instantiate VNF completion, operating the management information object instance and operating the mapping relationship between the management information object instance and the VNF instance comprises:
creating the management information object instance corresponding to the VNF instance, and creating the mapping relationship between the management information object instance and the VNF instance; and
sending a notification message for creation of the management information object instance to the OSS/NMS;

when the management information object Instance operation request message is a request message, sent by the OSS/NMS, for deletion of the management information object instance corresponding to the VNF instance, and the parameter carried in the request message comprises the DN of the management information object instance corresponding to the VNF instance, operating the management information object instance and operating the mapping relationship between the management information object instance and the VNF instance comprises: deleting the management information object instance corresponding to the VNF instance, and deleting the mapping relationship between the management information object instance and the VNF instance;
when the management information object, instance operation request message is a request message, sent by the OSS/NMS, for deletion of the management information object instance, and the request message carries a parameter indicating triggering of Terminate VNF, operating the management information object instance and operating the mapping relationship between the management information object instance and the VNF instance comprises:
sending a Terminate VNF request message to the VNFM according to the request message;
receiving a Terminate VNF confirmation message sent by the VNFM; and
deleting the management information object instance corresponding to the VNF instance, and deleting the mapping relationship between the VNF instance and the management information object instance,

message, sent by the OSS/NMS, for upd
