1. A control plane function network element, comprising:
a memory configured to store program instructions; and
a processor coupled to the memory and configured to execute the program instructions, such that during an establishment or a modification of a protocol data unit (PDU) session of a terminal in a first network, the program instructions cause the control plane function network element to:
send a bearer identifier request to a mobility management network element to request to allocate a bearer identifier for the PDU session;
receive a bearer identifier allocated to each bearer of at least one bearer from the mobility management network element, wherein the at least one bearer is included in a packet data network (PDN) connection in a second network that corresponds to the PDU session in the first network; and
obtain tunnel information of the PDN connection, wherein the tunnel information comprises user plane tunnel information corresponding to each bearer of the at least one bearer.
