It should be further noted that, for convenience of description, only some, but not all of the structures related to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a flowchart of a method for configuring node connection based on link interference according to an embodiment of the present invention, where an embodiment of the present application specifically includes the following steps:
step S101, a first node acquires topology information data, determines a plurality of connectable nodes according to the topology information data, and sends detection data to each connectable node.
In one embodiment, the first node may be an IAB node, and the topology information data records include nodes and node connection relationships in the first node and other networks of the same group. Optionally, the first node may be a node of a certain designated hierarchy in the network or a child node under a certain parent node, where the determining manner of the connectable node may be that the first node sends probe data to other nodes under the same network according to the topology relationship recorded in the topology information data, that is, all other nodes under the same network are used as connectable nodes. Preferably, the target node for sending the probe data can be a node of the same level as the parent node of the first node or a node of a level higher than the parent node, namely the nodes can be obtained as connectable nodes according to the topological relation; other nodes with configurable connection relations which are preset when the topology structure is generated can be adopted, and after the topology information data are acquired, the connectable nodes can be correspondingly and sequentially determined. The probe data is a kind of testing data, which is different from the content of the normal transmission data, but has the same transmission form.
In one embodiment, as shown in fig. 2, fig. 2 is a flowchart of a method for transmitting probe data according to an embodiment of the present invention, including:
step S1011, determining a plurality of different node levels and connectable nodes corresponding to each node level according to the topology information.

In one embodiment, sending probe data is performed during normal communication of the node, i.e., the node generates probe data and sends values to other nodes during normal communication of the currently connected node. Wherein different probe data are sent for connectable nodes of different node levels to distinguish.
Step S102, each connectable node generates first interference information according to the received plurality of detection data, and sends the first interference information to connectable nodes of the same level.
In one embodiment, for each connectable node, probe data for a plurality of first nodes may be received, and based thereon first interference information is generated and transmitted to connectable nodes of the peer. Optionally, the first interference information includes an interference value and a first communication function parameter, where the interference value is calculated in a process of detecting data communication, and the first communication function parameter includes a time parameter and/or a frequency parameter, where the time parameter records a time when the node communicates normally with the current node, and the frequency parameter records a frequency when the node communicates normally with the current node.

step S1021, after each connectable node receives the detection data of a single node, generating node interference information based on the set interference parameter generation rule.
Step S1022, combining the obtained interference information of multiple nodes to obtain first interference information, where the first interference information includes an interference value of each first node.
The generating of the interference information includes generating based on a set interference parameter generating rule, where the interference parameter generating rule may be converting relevant parameters of specific detection data into interference information, specifically, interference values.

Step S103, each connectable node determines node connection configuration information according to the generated first interference information and the received second interference information, wherein the node connection configuration information records an adjusting node and configuration nodes of the adjusting node.
In one embodiment, after each connectable node generates the first interference information, the synchronization receives the second interference information sent by other connectable nodes, where the second interference information is generated by other nodes and is recorded as the second interference information, and the generation manner is the same and is not repeated. The connectable node determines node connection configuration information based on the generated first interference information and the received second interference information, wherein the node connection configuration information records an adjusting node and a configuration node of the adjusting node, the adjusting node is a node needing to be adjusted for connection change, and the configuration node is a node needing to be configured for access by the adjusting node.

Step S1032, for the adjustment node, obtaining the interference value in each corresponding second interference information, and determining the configuration node based on the interference value in the second interference information.
The second interference information records information generated by the corresponding node based on the detection data sent by the first node. An interference value calculated by the first node to the connectable node is recorded. Optionally, when the configuration node of the adjustment node is determined by matching, a node with the minimum interference value is selected as the configuration node based on the interference value of the same first node in different interference information. And corresponding node connection configuration information, wherein each adjustment node and corresponding configuration node are recorded in the node connection configuration information.
