Method, Device and System for Detecting Data Link

摘要

Disclosed are a method, device and system for detecting a data link, a controller and a gateway. The method comprises the steps that a UGW receives context information, sent by the SDN controller, of a GTP user plane; and the UGW detects a data link between the gateways according to the context information of the GTP user plane. By means of the method, device and system for detecting a data link, the controller and the gateway, the problem that in the related art, the logic of the user plane and the logic of a control plane are unclear during detection of the data link between GTP endpoints is solved, and the effect of improving the clarity of the logic of the user plane and the logic of the control plane is achieved.

1. A method for detecting a data link, comprising:
receiving, by a Unified Gateway (UGW), context information, sent by a Software Defined Network (SDN) controller, of a General Packet Radio Service Tunnelling Protocol (GTP) user plane; and detecting, by the UGW, a data link between the UGW and a GTP endpoint according to the context information of the GTP user plane.
