Abstract: Embodiments of the present invention provide a method, an apparatus and a system for handling node failure. The method for handling node failure includes: sending, by an intermediate node, a context processing request message to a remote node when detecting that a first node occurs a failure, where the context processing request message is used to instruct the remote node to delete context information associated with the first node and the intermediate node; and deleting the context information associated with the first node and the intermediate node, by the remote node, according to the request message. The technical solution can enable the remote node to process the context information associated with the first node in time

Abstract: A method, a device, and a system for controlling tunnel identifier allocation are provided. The method includes: determining whether a type of a current procedure allows a Serving Gateway (SGW) to change a Tunnel Endpoint Identifier (TEID) and/or an Internet Protocol (IP) address (S110); and sending a modify bearer request message to the SGW, in which the modify bearer request message is used for notifying the SGW of whether the SGW is allowed to change the TEID and/or the IP address (S120). The loss of service data packets of a user or the service interruption caused by that the SGW modifies the TEID and/or the IP address is avoided.
