A data processing method and device includes a data selecting unit of a GGSN selecting data received by the GGSN, which includes a GTP tunnel signaling packet and a normal data packet and performs corresponding processing in accordance with a type of the selected packet. A data information processing unit receives data transmitted from the data selecting unit and data transmitted from an external data network. The data selecting unit is added in the GGSN, so that the data with respect to the GTP tunnel is managed by categories, and the tunnel deleting notification packet is transmitted to the data information processing module in time, thus a wrong data forwarding is avoided, and the operation mode is simple. In other words, the data information processing module operates only in the routing mode; therefore, the failure rate of a single node is reduced, and the operation cost is lowered.
