Claim 5:
6. A communication method of a wireless backhaul network, wherein the method is applied to a serving base station node in a wireless backhaul network, the wireless backhaul network comprises: at least one tree topology structure, each of the at least one tree topology structure comprises the serving base station node and at least one relay node, wherein a root of the tree topology structure is the serving base station node; a relationship between any two nodes in the wireless backhaul network is a child-parent relationship or non-child-parent relationship, and the any two nodes with the child-parent relationship communicate through a wireless connection; wherein each relay node in the tree topology structure has a unique parent node; when a User Equipment, UE, accesses from one of the at least one relay node of the wireless backhaul network, a path for data communication between the UE and the service base station node is uniquely determined as: a path from the one relay node to the serving base station node through parent nodes in turn;
wherein the method comprises:
receiving an access request transmitted by the UE;
processing the access request, generating an access response, and configuring a service transmission path for the UE;
sending the access response and the service transmission path to the UE;
receiving a measurement report reported by the UE in a process of performing service transmission with the UE based on the service transmission path; wherein the service transmission path is a current path that is uniquely determined between the UE and the service base station node; and
configuring a new service transmission path for the UE according to the measurement report, and sending the new service transmission path to the UE, so that the UE performs service transmission with the serving base station node based on the new service transmission path.
