Gtp-u tunnel error processing method and device

A General Packet Radio Service Tunnel Protocol User (GTP-U) tunnel error processing method and a device are provided. The method comprises: an agent node receives a GTP-U error indication sent by an agented node or a core network node, wherein an S1 User (S1-U) is respectively built between the agent node and the agented node and between the agent node and the core network node (S501); and the agent node disposes the GTP-U error indication according to the type of a control plane interface between the agent node and the agented node, wherein the different GTP-U tunnels are managed by different types of the control plane interfaces (S502). With the invention, the problem that the GTP-U error, which occurs after the agent node is introduced into the traditional system architecture, cannot be processed by an abnormal processing system is solved, thereby ensuring the stable running of a system.
