Title:
COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/210546
Kind Code:
A1
Abstract:
A communication control method according to an aspect of the present invention is used in a cellular communication system. The communication control method comprises receiving, by a relay node, a recovery attempt notice which is from a first parent node of the relay node and which indicates that the first parent node is trying to recover from a failure that has occurred in a backhaul link between the first parent node and a node that is a parent node of the first parent node. The communication control method further comprises transferring, by the relay node, a first packet received from the first parent node to a child node of the relay node in response to reception of the recovery attempt notice, and transferring, by the relay node, a second packet received from the child node to a second parent node which is a parent node of the relay node.
