Abstract: This application relates to the field of communications technologies, and discloses a network slice management method, device, and system, to solve the problem of low efficiency of manually deploying a network slice. One example network slice management method comprises obtaining, by a network management unit, the capability description information of a network slice, where the capability description information of the network slice includes at least one of a feature of the network slice and a deployment capability of the network slice. The method further comprises sending, by the network management unit, a notification message carrying the capability description information of the network slice, to a service management unit.

Abstract: A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.
