The method includes: after receiving a management request of a network slice, obtaining or determining, by a network slice manager, network resource information corresponding to a subnet included in the network slice, and then sending, in a form of a subnet management request to a subnet manager, the network resource information corresponding to the subnet, so that the subnet manager configures the corresponding subnet based on the network resource information corresponding to the subnet. In this application, network slice configuration efficiency can be improved. ## Claims ### Claim 1 A network slice manager, comprising at least one processor, and one or more memories coupled to the at least one processor, wherein the one or more memories are configured to store non-transitory computer-readable instructions, and wherein the at least one processor is configured to execute the non-transitory computer-readable instructions to cause the network slice manager to: determine or obtain transport resource information corresponding to a first subnet comprised in a network slice, wherein the first subnet is an access network (AN) subnet or a core network (CN) subnet, wherein the transport resource information is for configuring a communication connection between the first subnet and a second subnet comprised in the network slice;
