[0003] In order to detect and sense targets in all directions, a wireless data link network needs to be established between group nodes, and the data of this node is sent to other nodes in the sensor radio frequency beam to achieve information sharing.

[0004] When multiple radio frequency signals work simultaneously in the same task area with limited communication resources, mutual interference will occur, thereby reducing the persistence of detecting target tracking and the reliability of high-speed data transmission between network nodes. Summary of the Invention

[0011] In a second aspect, embodiments of the present application provide a communication resource allocation apparatus for a communication system, which is applied to any network node of a multi-array directional antenna network. The apparatus includes: A starting module for constructing a to-be-transmitted path starting from the network node and obtaining historical transmission paths participated by the network node.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0023] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, the term "and / or" in the description and claims is used to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of this application, the term "a plurality of" refers to two or more, and other quantifiers are similar.

[0024] A mobile multi-plane phased radar communication system usually achieves omnidirectional coverage in the airspace by fixedly loading multiple antenna arrays in multiple directions of a vehicle. When performing omnidirectional detection and perception of a target, in addition to the current network node completing the perception and analysis work, the network nodes in the communication system also need to complete the shared perception and analysis work.

[0025] To achieve the purpose of shared perception and analysis of network nodes in the communication system, a wireless data link needs to be established between network nodes for data mutual transmission and sharing. The current network node modulates the sensor perception data and analysis result data in the sensor radio frequency beam and sends it to other network nodes in the communication system for data aggregation to achieve the purpose of information sharing. The multi-antenna array sensor has a large transmission power, a high receiving gain, can track multiple targets, and has a strong comprehensiveness in various perception tasks. There are certain requirements for the high-speed and low-latency data transmission channel between network nodes in the communication system.

[0026] The data transmission between network nodes uses narrow-beam radio frequency transmission, and the spectrum resources are limited. In the same task area, if different data transmission tasks overlap in time and space, that is, the path to be transmitted and the historical transmission path perform data transmission at the same time sequence, and the transmission directions of the transmission paths in space are the same, the beams propagated under the two paths will be superimposed, affecting the information carried in the beam, and interfering with and conflicting with the data parsing of the receiving network node. Moreover, the mobile multi-plane phased radar communication system is in a mobile formation, and the formation network mechanism is a multi-hop self-organizing network method. It is easy for the beams to coincide due to the same-direction transmission in the transmission task. Once the beams coincide, the bandwidth of the fixedly allocated service resources will decrease, the received data will have errors, and the continuity of the detection data will be damaged, resulting in the failure of target tracking.

[0027] To avoid interference caused by co-directional transmission of narrow-beam radio frequencies, the communication resources in the communication system are reallocated to avoid the impact of interference. The communication resources in the communication system mainly refer to time resources and space resources. When performing a transmission task, each transmission task will occupy a certain amount of time resources, and the space resources refer to that each antenna array surface can generate multiple beams with different directions to cover different nodes, so as to complete point-to-point and point-to-multipoint service transmissions.

[0028] As Figure 1 shown, the embodiment of the present application proposes a step flowchart of a communication resource allocation method for a communication system, which is applied to any network node of a multi-array directional antenna network. As Figure 1 shown, the method may include: Step 101, construct a to-be-transmitted path starting from the network node, and obtain the historical transmission paths participated in by the network node; Among them, the to-be-transmitted path is a newly created transmission path, which is used to carry out new data transmission tasks. The historical transmission path is a transmission path that has already carried out data transmission work. At this time, the to-be-transmitted path and the historical transmission path may generate interference anomalies due to co-directional transmission, affecting the data parsing of the network node responsible for receiving in the transmission task.

[0029] In the embodiment of the present application, the current network node has information about the current node's data transmission work, including the constructed to-be-transmitted path starting from the current network node and the historical transmission paths participated in by the current network node. The to-be-transmitted path and the historical transmission path include the starting network node, forwarding network node, and target network node information in the path. In the historical transmission path, the current node can be the starting network node or the target network node of the data transmission work. The historical transmission path is segmented according to each segment of the transmission. When the current network node is a forwarding network node, the current network node is the target network node in the previous segment and the starting network node in the next segment.

[0030] In some embodiments, the current network node will send the historical transmission path in the current network node to other network nodes in the communication system according to the sharing period, and receive the historical transmission paths sent by other network nodes.

[0031] For example, the sharing period is 100 milliseconds. The current network node sends the historical transmission path in the current node to other network nodes every 100 milliseconds, and other network nodes will also send their own historical transmission paths according to the sharing period, which are received by the current network node, realizing the sharing of historical transmission paths.

[0032] Step 102: Compare the transmission directions of the to-be-transmitted path with each of the historical transmission paths to obtain a comparison result; In the embodiments of the present application, the beam width of the narrow-beam radio frequency used by the network node for data transmission is about 10°. When the transmission directions of the to-be-transmitted path and the historical transmission path are less than 10°, it can be considered that the transmission directions of the to-be-transmitted path and the historical transmission path coincide.

[0033] For example, as Figure 2 shown in the schematic diagram of interference anomaly determination, the ray AB is the transmission direction of the to-be-transmitted path, and the beam emitted by the starting network node A propagates within the range of ray AB ± 5°. The ray CD is the transmission direction of the historical transmission path. Similarly, the beam of the starting network node C also propagates within the range of CD ± 5°. If the included angle α between ray AB and ray CD is less than 10° at this time, the beams emitted on the two paths will be superimposed, resulting in interference.

[0034] In some embodiments, the transmission path is divided according to the minimum transmission unit. Each divided path segment has a starting network node and a target network node. The ray formed from the starting network node to the target network node is used as the propagation direction of this path segment. It is determined whether the propagation directions of each path segment in the to-be-transmitted path coincide with those of each path segment in the historical transmission path.

[0035] In some embodiments, the transmission directions of the to-be-transmitted path and each historical transmission path at the same time sequence are compared, and the transmission directions of the to-be-transmitted path and each historical transmission path at the current time sequence are compared to determine whether there is an overlap in the transmission directions. By selecting the to-be-transmitted path and the historical transmission path at the same time sequence, at this time, the to-be-transmitted path and the historical transmission path are under the same time resource. At this time, the result of determining that there is interference anomaly in data transmission by the coincidence of the transmission directions will be more accurate.

[0036] Step 103: Determine the transmission status of the to-be-transmitted path according to the comparison result; In the embodiments of the present application, the comparison result is whether there is an overlap in the transmission directions of the to-be-transmitted path and the historical transmission path, that is, the included angle of the transmission directions is less than 10°. When there is an overlap in the transmission directions of the two paths, when there is an overlap in the transmission directions, there may be a situation where the beams are superimposed, resulting in interference. Therefore, the transmission status of the to-be-transmitted path is marked as having interference anomaly. When there is no overlap in the transmission directions of the two paths, there will be no interference anomaly.

[0037] For example, as shown in the figure, the ray AB represents the transmission direction of the to-be-transmitted path, and the ray CD represents the transmission direction of the historical transmission path. When the included angle α between the ray AB and the ray CD is greater than 10°, the beams emitted on the two paths will not overlap, so there will be no interference.

[0038] Step 104, when the transmission state indicates that there is interference anomaly in the to-be-transmitted path, adjust the data sending timing of the to-be-transmitted path and / or adjust the to-be-transmitted path to eliminate the interference anomaly; As shown in Table 1, it is a time resource division timing table. The time resources are divided into several timings, and the divided timings are used to execute two types of transmission tasks. For the control timing in the schematic diagram, it is used for information sharing between network nodes, such as sharing data such as the location information of the current network node and the information of the newly created to-be-transmitted path. For the data timing in the schematic diagram, it is used for sharing the sensing data and analysis results for performing sensing and analysis work.

[0039]

[0040] Table 1 In the embodiment of the present application, when the transmission state indicates that there is interference anomaly in the to-be-transmitted path, adjust the time resources used by the to-be-transmitted path, or adjust the space resources, or adjust both the time resources and the space resources to eliminate the interference anomaly. When adjusting the time resources, adjust the execution timing of the to-be-transmitted path with interference anomaly, and preferably adjust it to the timing when there is no historical transmission path performing data transmission in the time resources. When all timings in the timing table have historical transmission paths performing data transmission, adjust the execution timing of the to-be-transmitted path in the order of the timing table to reallocate the time resources, and detect whether there is still interference anomaly between the to-be-transmitted path and the historical transmission path in the adjusted execution timing. If there is, continue to adjust the execution timing of the to-be-transmitted path until the interference anomaly is eliminated; when adjusting the space resources, as Figure 3 shown in the path adjustment schematic diagram, add a forwarding network node C to the to-be-transmitted path AB to obtain the to-be-transmitted path ACB after adding the forwarding network node C. For the to-be-transmitted path AB, the transmission direction of the historical transmission path coincides with the ray AB. After adding the forwarding network node C, each section AC and CB of the to-be-transmitted path ACB does not coincide with the direction of the historical transmission path, thereby eliminating the interference anomaly; adjust both the time resources and the space resources, that is, when there is still interference anomaly after adjusting the time or space resources, reallocate both resources to eliminate the interference anomaly.

[0041] For example, for the to-be-transmitted path AB, after replacing all the time sequences divided by the time resources, there is still interference anomaly with the historical transmission paths for data transmission in each time sequence. Since the allocation of time resources can no longer eliminate the interference anomaly, for the to-be-transmitted path AB, a forwarding network node C is added, so that in the same data transmission time sequence, there is no historical transmission path with interference anomaly with paths AC and CB, that is, the interference anomaly is eliminated after allocating both time resources and space resources.

[0042] Step 105, perform data transmission based on the adjusted to-be-transmitted path.

[0043] In the embodiment of the present application, the adjusted to-be-transmitted path is used as the to-be-transmitted path for finally performing data transmission. At this time, there is no interference anomaly between the to-be-transmitted path and the historical transmission paths, so interference caused by the superposition of the emitted radio frequency beams will not occur, improving the stability and reliability of data transmission to meet the requirements of a multi-antenna array communication system for data transmission.

[0044] In summary, in the embodiment of the present application, by comparing the transmission directions of the to-be-transmitted path and the historical transmission paths, according to the comparison result, it is judged whether the transmission state of the to-be-transmitted path will be affected by the historical transmission paths. When the transmission state indicates that there is interference anomaly in the to-be-transmitted path, the communication resource allocation of the communication system is adjusted, and the time resources and / or space resources used for data transmission of the to-be-transmitted path are adjusted, and the interference anomaly is decomposed through resource scheduling. The communication resource allocation method of the communication system in the embodiment of the present application adjusts the transmission direction of the to-be-transmitted path through time resources and / or space resources. By adjusting the time resources, it is avoided that the to-be-transmitted paths with the same transmission direction and the historical transmission paths send data in the same time sequence. By adjusting the space resources, the transmission direction of the to-be-transmitted path is no longer the same as that of the historical transmission paths, avoiding mutual interference during data transmission and improving the transmission quality and stability of data transmission.

[0045] As Figure 4 shown, the embodiment of the present application proposes a step flowchart of a communication resource allocation method for a communication system, which is applied to any network node of a multi-array directional antenna network. As Figure 4 shown, the method may include: Step 201, construct a to-be-transmitted path starting from the network node, and obtain the historical transmission paths participated by the network node.

[0046] This step can specifically refer to the above step 101 and will not be elaborated here.

[0047] Step 202: Calculate the angles between the transmission direction of the to-be-transmitted path and the transmission directions of each of the historical transmission paths, and use the angles as the comparison results.

[0048] In the embodiments of the present application, calculate the angles between the transmission direction of the to-be-transmitted path and the transmission directions of each of the historical transmission paths. As Figure 2 shown, taking the to-be-transmitted path AB and one of the historical transmission paths CD as an example, taking the starting network node A of the to-be-transmitted path AB as the coordinate origin and the due north direction as the x-axis to establish a coordinate system. Among them, α is the angle between the to-be-transmitted path AB and the historical transmission path CD, and the calculation formula for the angle α is:

[0049] where the coordinates of A are ( ), the coordinates of B are ( ), the coordinates of C are ( ), the coordinates of D are ( ), and tanα is the sine value of the angle.

[0050] According to the calculated sine value of the angle α, determine the size of the angle α. In the same data sending time sequence, calculate the angles between the to-be-transmitted path and each of the historical transmission paths, and use the information of the angles as the comparison results.

[0051] Step 203: When there is an angle less than the preset angle in the comparison results, determine that the transmission state of the to-be-transmitted path indicates that there is interference anomaly in the to-be-transmitted path.

[0052] In the embodiments of the present application, when there is an angle less than 10°, it can be regarded that in the same data sending time sequence, there is a historical transmission path with interference anomaly with the to-be-transmitted path. Among them, the historical transmission path corresponding to the angle less than 10° is the path with interference anomaly with the to-be-transmitted path. The preset angle can also be other angles less than 10°, such as 5°. The present application does not make any restrictions here.

[0053] Among them, the more historical transmission paths with interference anomaly with the to-be-transmitted path, the stronger the interference conflict generated for the to-be-transmitted path. The smaller the angle after the angle is less than 10°, the stronger the interference conflict generated for the to-be-transmitted path.

[0054] Optionally, step 203 may specifically include: Sub-step 2031: When there is an angle less than the preset angle in the comparison results, and the network nodes in the historical transmission path corresponding to the angle less than the preset angle are within the transmission coverage range of the to-be-transmitted path, determine that the transmission state of the to-be-transmitted path indicates that there is interference anomaly in the to-be-transmitted path.

[0055] In the embodiments of the present application, as Figure 2 shown, taking the starting network node A of the to-be-transmitted path AB as the coordinate origin and the due north direction as the x-axis to establish a coordinate system, the azimuth angle ∠AB (the angle between the transmission direction and the due north direction x-axis) of the to-be-transmitted path AB is:

[0056] wherein, tan∠AB is the sine value of the azimuth angle ∠AB, and the coordinates of A are ( ), and the coordinates of B are ( ).

[0057] Then the beam coverage range for data transmission of the to-be-transmitted path AB is ∠AB ± 5°.

[0058] The azimuth angle between the network node A and the network node C in the historical transmission path is:

[0059] wherein, tan∠AC is the sine value of the azimuth angle ∠AC, and the coordinates of A are ( ), and the coordinates of C are ( ).

[0060] The azimuth angle between the network node A and the network node D in the historical transmission path is:

[0061] wherein, tan∠AD is the sine value of the azimuth angle ∠AD, and the coordinates of A are ( ), and the coordinates of D are ( ).

[0062] Affected by the earth's curvature, the maximum straight-line distance of radio transmission is 32 km. Beyond this distance, it will be blocked by the earth's surface. The distances between the network node A and the network nodes C and D are respectively: ,

[0063] where is the distance between A and C, is the distance between A and D, the coordinates of A are ( ), the coordinates of C are ( ), and the coordinates of D are ( ).

[0064] When the azimuth angles ∠AC and / or ∠AD are within the range of ∠AB ± 5°, and the distances between the network node A and the network nodes C and / or D are less than 32 km, it is determined that there is interference anomaly in the to-be-transmitted path.

[0065] Similarly, since the path AB to be transmitted can be two-way, it is necessary to calculate the transmission coverage range of network node B. The azimuth angle of ∠BA is:

[0066] where tan∠BA is the sine value of the azimuth angle ∠BA, and the coordinates of A are ( ), and the coordinates of B are ( ).

[0067] Calculate the azimuth angles of network node B with network node C and network node D respectively, and determine whether the azimuth angles are within the range of ∠BA±5° and the distance is within 32 km: ,

[0068] ,

[0069] where tan∠BC is the sine value of the azimuth angle ∠BC, tan∠BD is the sine value of the azimuth angle ∠BD, is the distance between B and C, is the distance between B and D, and the coordinates of B are ( ), the coordinates of C are ( ), and the coordinates of D are ( ). If network nodes C and D are within the range of ∠BA±5° and the distance is less than 32 km, it is determined that there is an interference anomaly in the path to be transmitted.

[0070] Step 204, when the transmission status indicates that there is an interference anomaly in the path to be transmitted, adjust the data sending timing of the path to be transmitted and / or adjust the path to be transmitted to eliminate the interference anomaly.

[0071] This step can specifically refer to step 104 above and will not be elaborated here.

[0072] Optionally, step 204 may specifically include: Sub-step 2041, select a data sending timing from a preset timing table as the data sending timing after adjusting the path to be transmitted; multiple data sending timings are recorded in the timing table, and the selected data sending timing is staggered from the data sending timing of the historical transmission path that causes the interference anomaly to eliminate the interference anomaly.

[0073] In the embodiments of the present application, when there is interference anomaly in the to-be-transmitted path, the data sending timing of the to-be-transmitted path is adjusted, and the data sending timing of the to-be-transmitted path is reselected, so as to eliminate the interference during data transmission and improve the transmission quality and stability of data transmission by allocating time resources.

[0074] In some embodiments, after reselecting the data sending timing of the to-be-transmitted path, the transmission directions of the to-be-transmitted path and the historical transmission path under the reselected data sending timing are compared, and according to the comparison result, it is determined again whether there is interference anomaly in the to-be-transmitted path under the new data sending timing. When there is no interference anomaly, the to-be-transmitted path uses the reselected data sending timing for data transmission. When there is still interference anomaly, a new data sending timing is selected again, and it is determined whether there is interference anomaly until the interference anomaly is eliminated.

[0075] For example, when the to-be-transmitted path performs data transmission at data timing 3 in Table 1, it is detected that there is interference anomaly between the to-be-transmitted path and the historical transmission path. At this time, according to the timing table, data timing 4 is used as the execution timing of the to-be-transmitted path, and it is detected whether there is interference anomaly between the to-be-transmitted path and the historical transmission path under data timing 4. If not, data timing 4 is used as the data sending timing of the to-be-transmitted path. If there is interference anomaly, new timings are sequentially selected according to the timing table, and it is detected whether there is interference anomaly between the to-be-transmitted path and the historical transmission path in the new timings until the interference anomaly is eliminated.

[0076] Optionally, step 204 may specifically include: Sub-step 2042: Select a network node from all the network nodes included in the historical transmission path as a forwarding network node and add it to the to-be-transmitted path to obtain an updated to-be-transmitted path; the transmission direction of each segment of the updated to-be-transmitted path is different from that of the historical transmission path to eliminate interference anomaly.

[0077] In the embodiments of the present application, in addition to allocating time resources to eliminate interference anomaly, the space resources can also be adjusted, that is, a forwarding network node is added to the to-be-transmitted path. A network forwarding node is selected from the network nodes included in the historical transmission path and added to the to-be-transmitted path to change the transmission direction of each segment of the to-be-transmitted path, so as to avoid overlapping with the transmission direction of the historical transmission path and eliminate interference anomaly.

[0078] In some embodiments, after adding a forwarding network node to the path to be transmitted, each segment of the path to be transmitted is compared with the transmission direction of the historical transmission path. According to the comparison result, it is determined again whether there is interference anomaly in the new data transmission timing of the path to be transmitted. When there is no interference anomaly, the new path to be transmitted is used for data transmission. When there is still interference anomaly, a new network forwarding node is added again, and it is judged whether there is interference anomaly until the interference anomaly is eliminated.

[0079] Optionally, step 204 may specifically include: Sub-step 2043, in a preset timing table, select a data transmission timing as the data transmission timing after the adjustment of the path to be transmitted; Sub-step 2044, when all the data transmission timings in the timing table have been traversed and the transmission timing of the path to be transmitted has been adjusted, and there is still interference anomaly between the path to be transmitted and the historical transmission path, select a network node from all the network nodes included in the historical transmission path as a forwarding network node and add it to the path to be transmitted to obtain an updated path to be transmitted; the transmission direction of each segment of the updated path to be transmitted is different from the transmission direction of the historical transmission path respectively to eliminate the interference anomaly.

[0080] Regarding sub-steps 2043-2044, when there is interference anomaly between the path to be transmitted and the historical transmission path, the data transmission timing of the path to be transmitted is preferentially adjusted. When all the timings in the timing table have been swapped and there is still interference anomaly between the path to be transmitted and the historical transmission path, the time resource can no longer adjust the interference between the path to be transmitted and the historical transmission path. The space resource is allocated for adjustment, and a forwarding network node is added to the path to be transmitted to eliminate the interference anomaly. The time resource is allocated first, and then the space resource is allocated to avoid the data transmission path of the multi-faceted phased array radar communication system becoming more and more complex and the task volume of interference anomaly judgment increasing.

[0081] Step 205, perform data transmission based on the adjusted path to be transmitted.

[0082] This step may specifically refer to step 105 above and will not be elaborated here.

[0083] Optionally, the method further includes: Step 206, obtain the node position information sent by each of the remaining network nodes in the antenna network.

[0084] In the embodiments of the present application, since the multi-faceted phased array radar communication system is in a mobile formation and the positions of the network nodes in the historical transmission paths are constantly changing, it is easy to have abnormal interference between the historical transmission paths due to the position changes of the network nodes. Therefore, it is necessary to obtain the latest positions of the network nodes in the historical transmission paths.

[0085] As Figure 5 shown in the architecture diagram of the communication system, network node A obtains the node position information sent by each of the other network nodes, such as network node B, network node C, and network node D. For the other network nodes, they also need to obtain the position information of network node A. Therefore, it is also necessary for network node A to send its own latest position information to the other network nodes to periodically establish and maintain control message interaction, form an available routing table among the network nodes, and maintain the topological relationship among them. When the updated node information sharing is completed, the current node shares the sensing data and analysis results with the other nodes through the historical transmission path and receives the data sent by the other nodes. It periodically detects whether there are abnormal interference situations in each network node in the historical transmission path due to movement. When an abnormal interference situation is detected, the historical transmission path is adjusted according to the starting point number, and the starting network node is notified to reconstruct the historical transmission path and reallocate the time resources and / or space resources of the historical transmission path to eliminate the abnormal interference situation.

[0086] In some embodiments, the current network node sends position information to the other network nodes according to a fixed sharing period and receives the position information sent by the other network nodes. The sharing period is set to 100 milliseconds, and the position information of each network node in the multi-faceted phased array radar communication system is shared regularly to ensure the timeliness of the position information data. Step 207, update the position information of the network nodes in the historical transmission path through the node position information.

[0087] In the embodiments of the present application, when the current network node receives the node information sent by the other network nodes, it uses the latest node information to update the position information of the network nodes in the historical transmission path, so as to keep the positions of the nodes in the historical transmission path in the current node up-to-date and avoid the information recorded in the current network node from becoming invalid due to the movement of the network nodes.

[0088] Step 208, after the update is completed, compare the transmission directions between the historical transmission paths under the same data sending time sequence to obtain a comparison result.

[0089] In the embodiments of the present application, the transmission directions between the updated historical transmission paths are judged to avoid abnormal interference situations in the existing historical transmission paths due to the movement of the network nodes.

[0090] Step 209. Determine the transmission status among the historical transmission paths according to the comparison result.

[0091] In the embodiment of the present application, it is detected whether there is interference abnormality in the historical transmission path and eliminated, so as to ensure that the historical transmission paths do not interfere with each other. Therefore, when adding a path to be transmitted, it is only necessary to determine whether there is interference abnormality between the path to be transmitted and the historical transmission path, so as to ensure that there is no interference abnormality in the multi-faceted phased radar communication system.

[0092] Step 210. When the transmission status indicates that there is interference abnormality among the historical transmission paths, adjust the data sending time sequence of the historical transmission paths and / or adjust the historical transmission paths to eliminate the interference abnormality.

[0093] In the embodiment of the present application, for the situation where interference abnormality occurs among the historical transmission paths due to the movement of network nodes, the interference abnormality is also eliminated by allocating time resources and / or space resources.

[0094] In some embodiments, when the current network node shares location information with other network nodes, it also shares the quality information of the data transmitted in the historical transmission path. When the quality information indicates that the data transmission quality of the current path decreases, although data transmission can continue, continuous quality decrease will lead to the interruption of the path. Therefore, when the data transmission quality of the historical transmission path decreases, time resources and / or space resources are re-allocated to the historical transmission path, and the path is re-constructed. After the new path is successfully constructed, the re-constructed path is used for data transmission, and the path with decreased quality is released.

[0095] Optionally, the network node has the priority of the historical transmission path and the starting point number of the historical transmission path. Step 210 may specifically include: Sub-step 2101. When there is interference abnormality among the historical transmission paths, adjust according to the priority in the historical transmission paths. The adjustment order of the historical transmission paths with lower priority levels is earlier.

[0096] In the embodiment of the present application, when interference abnormality occurs among the historical transmission paths, it is often that multiple historical transmission paths affect each other, which does not mean that all historical transmission paths need to be adjusted. It is only necessary to adjust some historical transmission paths with interference abnormality. The current network node has the priority of the historical transmission path. According to the priority, the historical transmission paths that need to be adjusted are selected. The adjustment order of the historical transmission paths with lower priority levels is earlier.

[0097] For example, there is interference anomaly in historical transmission paths CD and EF. The priority of CD is "high" and the priority of EF is "low". Since the priority of CD is high and the data transmitted is more important, it needs to be transmitted preferentially. Therefore, the adjustment order of EF with a lower priority level is earlier, and the historical transmission path EF is adjusted first.

[0098] Sub-step 2102: For the historical transmission paths with the same priority, adjust according to the starting point numbers of the historical transmission paths. The historical transmission path with a larger starting point number has an earlier adjustment order.

[0099] In the embodiment of the present application, for the historical transmission paths with the same priority, adjust through the starting point numbers of the historical transmission paths available in the current network node. The historical transmission path with a larger starting point number has an earlier adjustment order.

[0100] For example, there is interference anomaly in historical transmission paths CD and EF. The starting point number of the starting network node of historical transmission path CD is "003", and the starting point number of the starting network node of historical transmission path EF is "005". The network node with a smaller starting point number starts working earlier and may have a larger task volume, and it is more inconvenient to allocate time resources and / or space resources. While the network node with a larger starting point number may have a smaller task volume, and due to the development of technology, it has good performance and rich communication resources. Therefore, the historical transmission path with a larger starting point number has an earlier adjustment order, and historical transmission path EF is adjusted.

[0101] In summary, in the embodiment of the present application, by comparing the transmission directions of the path to be transmitted and the historical transmission paths, according to the comparison result, it is judged whether there is an overlap in the transmission directions of the path to be transmitted and the historical transmission paths, which may affect the data transmission effect. When there is interference anomaly in the path to be transmitted, adjust the communication resource allocation of the communication system, and adjust the time resources and / or space resources used for data transmission of the path to be transmitted, and decompose the interference anomaly through resource scheduling. For the interference anomaly of the historical transmission path caused by the movement of the network node, also eliminate the interference anomaly by adjusting the communication resources. The communication resource allocation method of the communication system in the embodiment of the present application adjusts the transmission direction of the path to be transmitted through time resources and / or space resources. By adjusting the time resources, it is avoided that the path to be transmitted and the historical transmission path with the same transmission direction send data in the same time sequence. By adjusting the space resources, the transmission direction of the path to be transmitted is no longer the same as that of the historical transmission path, avoiding mutual interference during data transmission and improving the transmission quality and stability of data transmission.
