Abstract: Embodiments of the application provide a method and an apparatus for managing a network slice. A first update request message sent by a second network device is received by a first network device. The first update request message carries network slice requirement information. The network slice requirement information is used to indicate that a network resource of a first network slice needs to be updated to a first network resource. A second network resource that can be actually provided for the first network slice is determined by the first network device based on the first update request message. An update acknowledgement message is sent by the first network device to the second network device. The update acknowledgement message is used to instruct to update the network resource of the first network slice based on the second network resource.
