1. A method for handling of a failure of a user plane path between an access network and a core network in a telecommunication network, comprising:
receiving, by a Mobility Management Entity (MME) in the core network and from a first endpoint of a user plane path, a notification regarding a failure on the user plane path between the access network and the core network;
handling, by the MME, the failure on the user plane path, wherein the handling comprises:
marking the user plane path as being temporarily unavailable; and
attempting to re-establish the user plane path based on the user plane path being marked temporarily unavailable;
wherein the first endpoint is one of a base station (BS) and a Serving Gateway (SGW); and
wherein a second endpoint of the user plane path is the other of the BS and the SGW.
