Abstract: The embodiments of the present invention provide a tunnel fault detection method and a traffic engineering (TE) node. The method includes: receiving, by a traffic engineering TE node, a link fault report packet; determining, by the node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the node, whether one or more tunnels which use the node as an ingress node and pass through the faulty link exist; and identifying the tunnels as faulty tunnels if the one or more tunnels which use the node as the ingress node and pass through the faulty link exist. In the embodiments of the present invention, the TE node can detect all faulty tunnels at a time, and it is not necessary to wait until the fault notification based on each tunnel is received and then the faulty tunnel is identified one by one.

Abstract: A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.
