Claim of US Patent No. 10,397,969

6. A base station, comprising:a processor; and
a memory for storing instructions executed by the processor;
wherein the processor is configured to:
broadcast system information to cause at least one first terminal receiving the system information to return backhaul link establishment signaling, wherein the at least one first terminal has established a first communication link with a core network;
receive the backhaul link establishment signaling returned by the at least one first terminal, the backhaul link establishment signaling being configured to indicate the at least one first terminal to establish a first backhaul link for the base station; and
send a confirmation message to the at least one first terminal to cause the at least one first terminal to establish a second communication link with the base station after receiving the confirmation message, the second communication link and the first communication link forming the first backhaul link;
wherein when the base station has established multiple backhaul links that comprise the first backhaul link, with respective first terminals that comprise the at least one first terminal, the processor is further configured to:
receive at least one data packet sent by at least one second terminal located in a coverage of the base station;
acquire a quality of service class identifier (QCI) of the at least one data packet, the QCI being configured to indicate a communication priority of the at least one data packet; and
allocate the at least one data packet to the multiple backhaul links on the basis of current remaining bandwidths of the multiple backhaul links and the QCI of the at least one data packet.
