1. A network access method, comprising:
receiving, by a second network device, access capability information from a first network device through an E1 interface, wherein the first network device is a CU-user plane (CU-UP), the second network device is a CU-control plane (CU-CP), wherein the first network device is a network device of a first-type network, the access capability information indicates a capability of the first network device to access a second-type network, and the first-type network is different from the second-type network, wherein the access capability information comprises a list of network identifiers of the second-type network that is allowed to be accessed by at least one cell, wherein the first-type network is a public land mobile network (PLMN), and the second-type network is a stand-alone non-public network (NPN); or the first-type network is a stand-alone NPN, and the second-type network is a PLMN, wherein the access capability information further comprises a list of slices that are allowed to be accessed by the at least one cell and a configured cell list of the NPN; and
using, by the second network device, the access capability information.
