Tunnel management method, tunnel management apparatus, and communications system

摘要

The present invention relates to communications technologies and discloses a tunnel management method, a tunnel management apparatus, and a communications system so that a node that causes failure of a tunnel management request can be determined. According to the present invention, a response returned by a tunnel management node to an initiating node includes not only a cause value of tunnel management request failure but also information of the node that causes failure of the tunnel management request, so that the initiating node can find the node that causes failure of the tunnel management request and determine the error checking direction. The present invention is applicable to network devices in a communications network.

主权项

1. A tunnel management method performed by a serving gateway (S-GW) in an evolved packet system (EPS) network, comprising:
receiving, by the S-GW in the EPS network, a tunnel management request from an initiating node; and sending, by the S-GW, a response message to the initiating node, wherein the response message sent to the initiating node comprises a cause value indicating a cause of a failure of processing the tunnel management request and information indicating which node caused the failure of processing the tunnel management request.
