Problems solved by technology

[0003] The inventor found that in the prior art, when the root node sends data to the leaf node and then to the terminal, it may be that a node in the path has no remaining bandwidth, which makes the delivery unsuccessful, thereby wasting network resources and As for the low utilization of network bandwidth

Embodiment 1

[0029] The node bandwidth management method provided by the embodiment of the present invention, such as figure 2 As shown, the method steps are as follows:

[0030] S201. If the data that needs to be sent to the terminal through the first leaf node is detected, search for a path from the first leaf node to the root node according to the path table, and the path table is used to store paths from each leaf node to the root node.

[0031] Exemplarily, in the path table above, the first column can be used to store the number of each node, the second column can be used to identify whether the node is a root node, the third column can be used to store the upper-level node of each node, and the fourth column can be used to store the node remaining bandwidth.

[0032] Wherein, searching for a path from the first leaf node to the root node according to the path table can be exemplified as: searching for the upper-level nodes of the first leaf node level by level according to the abo...

Embodiment 2

[0037] In Embodiment 2 provided by the present invention, an example diagram of a network topology is given, such as image 3 As shown, leaf node 1 (base station 1) is connected to leaf node 2 (base station 2), and leaf node 2 (base station 2) is connected to another leaf node x (base station x), and leaf node x is connected to root node y (base station control device y) connection. In this embodiment, the root node y includes a node bandwidth management device.

[0038] Exemplarily, two storage areas RAM A and RAM B can be set at the root node y to store the path table, such as Figure 4 Shown, RAM A preserves the topological structure of the network, and its data structure can be: save the serial number of each node (the serial number can be the address of each node) with the first column, whether this node is the root node with the second column identification, such as root The node ID is 1, and the non-root node ID is 0. Use the third column to save the number of the upp...

Embodiment 3

[0056] The structure diagram of the node bandwidth management device provided by the embodiment of the present invention is as follows Figure 5 As shown, the device includes a storage unit 501 , a search unit 502 , a judgment unit 503 , and a sending unit 504 .

[0057] The storage unit 501 is configured to save a path table, and the path table is used to save a path from each leaf node to the root node;

[0058] The search unit 502 is configured to search for a path from the first leaf node to the root node according to the path table stored in the storage unit 501 if data that needs to be sent to the terminal through the first leaf node is detected;

[0059] Exemplarily, the root node can be a base station controller, and the leaf nodes can be base stations. For the structure of the path table, see Figure 4 , use the first column to save the number of each node, use the second column to identify whether the node is the root node, for example, the root node is marked as 1,...

Abstract

An embodiment of the invention provides a node band width management method, a device and a system thereof. The invention relates to communication field and can increase the usage factor of network band width. The solution of the invention is that a path from a first leaf node to a root node is searched according to a path table when the requirement of data transmission through the first leaf node to the terminal is detected. The path table is used for storing the path from each node to the root node. If each node in the path has residual band width, the data is transmitted to the leaf node through the path so as to facilitate the data transmission of the first leaf node to the terminal. The node band width management method, device and system of the invention is used for managing band width of each node by the network management side.

Description

technical field [0001] The present invention relates to the communication field, in particular to a node bandwidth management method, device and system. Background technique [0002] Wireless networks, including base stations and base station controllers such as figure 1 As shown, the base station controller is located at the root node (indicated by R in the figure), and the hub function in the base station is used as a leaf node (indicated by H in the figure), one end of which is connected to the base station controller, and the other end is connected to the base station as a leaf node (Denoted by L in the figure) connected. The entire network forms a tree structure with the base station controller as the root node. The data of each leaf node comes from the root node, and the path from each leaf node to the root node is unique. [0003] The inventor found that in the prior art, when the root node sends data to the leaf node and then to the terminal, it may be that a node ...
