Claim 11:
12. A communication device, comprising:
a transceiver;
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
receive, by the transceiver, a first cell identifier and a network identifier from a first network element, wherein the network identifier comprises an identifier of a first private network and an identifier of a second private network;
obtain information about a second network element based on the first cell identifier and the network identifier, wherein the first network element serves a terminal device in the first private network, and wherein the second network element serves the terminal device in the second private network; and
send, by the transceiver, the first cell identifier and the network identifier to the second network element indicated by the information about the second network element, wherein the first cell identifier and the network identifier are used to obtain downlink routing information, and wherein the downlink routing information is used to indicate transmission of downlink data from a first user plane entity in the first private network to a second user plane entity in the second private network.
