Problems solved by technology
When a node with a small WiFi backhaul capacity needs to transmit a large amount of data, the backhaul link will cause data delay or discard due to the slow transmission rate.
When the total amount of data to be transmitted by a node with a large WiFi backhaul capacity is small, the backhaul link will be idle after the data is transmitted due to its fast transmission rate.
In this way, the transmission rate of each node in the network varies greatly, resulting in the deterioration of the transmission quality of the entire network.

The present application discloses a device and method for allocating backhaul resources. The device includes a receiving module, an allocating module, and a sending module; the receiving module is configured to receive request information sent by at least two nodes, wherein the request information is used by one of the at least two nodes to request to obtain The information of the spectrum resource is returned by the cell; the allocation module is used to allocate the total transmission rate of each node in the at least two nodes to the at least two nodes according to the request information received by the receiving module Cellular backhaul spectrum resources that meet the predetermined requirements, the total transmission rate is the sum of the transmission rate of the WiFi backhaul link and the transmission rate of the cellular backhaul link; the sending module is used to send to the at least two nodes Notification information, wherein the notification information includes the information of the cellular backhaul spectrum resource allocated by the allocation module for the corresponding node.
Description
【Technical field】 [0001] The present application relates to the field of communication networks, in particular to a device and method for allocating backhaul resources. 【Background technique】 [0002] In a wireless network where distributed base stations need to be deployed across a large area, the base stations need to be connected to the core network through some kind of backhaul. In traditional cellular networks, the backhaul usually consists of wired connections. However, with the development of wireless network communication technology, wireless fidelity (Wireless Fidelity, WiFi) technology is more and more widely used, and more and more base stations are connected to core network. [0003] The prior art provides a backhaul method. When the WiFi backhaul capability is insufficient, cellular backhaul is used at the same time, so as to ensure the quality of service (Quality of Service, QoS) of the backhaul. [0004] However, when multiple nodes in the wireless communic...
