Detection and handling of failure on user plane path

The present disclosure proposes a method of an end-point of a user plane path between an access network and a core network in a telecommunication network, comprising: detecting whether a failure exists on the user plane path or not; and notifying a node in the core network of the failure in order for the node to handle the failure, upon detecting the failure. With this method, the failure can be handled timely, thus minimizing the service interruption.
