METHOD FOR RE-ESTABLISHING ROUTE IN ULTRA-DENSE NETWORK (UDN), AND MICRO BASE STATION

摘要

The present invention relates to the technical field of ultra-dense networks. Disclosed is a method for re-establishing a route in an ultra-dense network (UDN) capable of eliminating overheads associated with periodic detection and solving a problem of interrupted or delayed transmission of data resulting from event-triggered detection. The main technical solution of the present invention comprises: a first routing node performing monitoring to find out satisfaction of a preset spatial separation condition of the first routing node with respect to a second routing node at upstream of a channel route where the first routing node is located or a third routing node at downstream of the channel route where the first routing node is located; and the first routing node sending a message to the third routing node at the downstream of the channel, such that the third routing node searches for a path to establish new channel routing. Also disclosed is a micro base station in a UDN.
