Title: METHOD FOR EXTENDING NETWORK SLICE INSTANCE, NETWORK DEVICES, AND NETWORK ARCHITECTURE
Abstract:
Embodiments of the present invention provide a method for extending a network slice, network devices, and a network architecture. The method comprises: a first network device obtains an extension request of a target network slice instance (NSI), the extension request being used for requesting to extend a network function of the target NSI; the first network device sends a configuration request to a second network device according to the extension request, the configuration request being used for requesting to configure a network function to be extended of the target NSI; the first network device receives a configuration response message sent by the second network device according to the configuration request, the configuration response message being used for indicating that the second network device has completed the configuration of the network function to be extended. The method for extending a network slice instance and the network devices provided in the embodiments of the present invention can implement the extension of a network function of a network slice instance by means of unified scheduling and management on physical resources and virtual resources, thereby improving user experience and saving network resources.
