Abstract: The present disclosure provides a data processing method, a node, a structure, and an apparatus. The method includes: receiving, by an aggregation node, a first non-access stratum message sent by user equipment (UE), where the aggregation node includes at least two types of interfaces, and each type of interface is used to receive a first non-access stratum message of one radio access technology (RAT) type; converting, by the aggregation node, the first non-access stratum message into a non-access stratum message in a first format based on a RAT type of the first non-access stratum message, where the first format is a non-access stratum message transmission format supported between the aggregation node and a core-network control plane entity; and sending, by the aggregation node, the non-access stratum message in the first format to the core-network control plane entity. A sink design of the aggregation node saves sending and receiving resources of a core network and improves packet forwarding efficiency.
