[0002] To meet the service requirements with different characteristics at different times, a mobile communication system has introduced a coverage adjustment mechanism, enabling the coverage of radio cells or beams in a Radio Access Network (RAN) to be dynamically adjusted. Typical coverage adjustment measures include adjusting the antenna tilt angle, adjusting the beam width, etc. Generally, the coverage adjustment of a cell or beam will affect the service performance of adjacent beams. Coverage adjustment often involves the joint adjustment of a cell or beam and its adjacent cells or beams. Although in some scenarios, unilateral adjustment of only one cell or beam is also feasible and beneficial.

[0003] To support more flexible network deployment, the 5G system has introduced a Central Unit (CU) / Distributed Unit (DU) separation mechanism. An RAN node (NG-RAN node) in a 5G system can be split into a CU and at least one DU, where the CU is connected to the core network, and the radio air interface is controlled by the DU. The CU and the DU are connected by an F1 interface or a W1 interface.

[0089] The embodiments of this application provide an information transmission method, device, and communication device to improve the performance of coverage adjustment and ensure the system performance after adjustment.

[0090] Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0091] As Figure 2 shown, the embodiments of this application provide an information transmission method, which is executed by a first network element in the radio access network and includes:

[0092] Step S201: Receive the key performance indicator (KPI) - related information of the third network element in the radio access network sent by the second network element in the radio access network. The KPI - related information includes at least one of the following: KPI information, KPI change information.

[0093] Among them, the KPI - related information is used to assist the first network element in performing coverage adjustment.

[0094] It should be noted that by receiving the KPI - related information of the third network element in the radio access network sent by the second network element in the radio access network, coverage adjustment can be assisted based on this KPI - related information. By referring to the information of other network elements during coverage adjustment, the performance of coverage adjustment can be improved.

[0095] Optionally, in the embodiments of this application, the KPI refers to any statistic that can reflect the operating status of the radio access network. For example, it may include but is not limited to at least one of the following: total utilization rate of downlink physical resource blocks, NG - RAN handover success rate, the amount and rate of radio link failures of radio access network devices or radio cells, etc. It should be noted that the amount of radio link failures counts the number of times that radio links connected to a certain radio access network device or belonging to a certain radio cell are interrupted due to reasons other than controlled release and handover, and the radio link failure rate is the ratio of the amount of radio link failures to the total number of radio links connected to a certain radio access network device or belonging to a certain radio cell within the same time period.

[0096] It should be noted that the purpose of performing coverage adjustment mentioned in the embodiments of this application is specifically reflected in which KPI or which KPIs are optimized. This application does not limit which specific KPIs are optimized.

[0097] It can be understood that reducing interference in the radio channel and filling radio coverage holes are the most typical goals of coverage adjustment. Because interference in the radio channel usually causes the transceiver of information to use a more conservative coding method to interact data, that is, it reduces the spectral efficiency, and then increases the total utilization rate of downlink physical resource blocks; while radio coverage holes will cause the signal strength of the source and target of the handover to be poor before and after the user equipment handover, and it is easier to drop the line before and after the handover, resulting in a lower handover success rate, a higher amount or rate of radio link failures. Therefore, to what extent the KPI can be improved, such as reducing the total utilization rate of downlink physical resource blocks, increasing the handover success rate, reducing the amount or rate of radio link failures, can be an important measure for whether a coverage adjustment is appropriate.

[0098] In the embodiments of this application, the KPI information refers to the value of the KPI at a specific moment; and the KPI change information refers to the change in the value of the KPI between different moments.

[0099] It should be noted that in the embodiments of the present application, the first network element refers to the DU, the second network element refers to the CU, and the third network element can be an access network element belonging to a different radio access network from the CU or another DU under the CU.

[0100] It should be noted that the first network element can assist in coverage adjustment based on KPI information or based on KPI change information. The following will separately describe different situations as follows.

[0101] I. The first network element needs to assist in coverage adjustment based on KPI information

[0102] It should be noted that when the first network element needs to assist in coverage adjustment based on KPI information, the second network element sends KPI information to the first network element. After obtaining the KPI information, the first network element can implement one of the following methods:

[0103] Method 1: The first network element trains a coverage adjustment decision model based on KPI information, and then inputs the input information of the model into the trained coverage adjustment decision model. When it is determined that coverage adjustment is required, the first network element performs coverage adjustment.

[0104] It should be noted that in this case, mainly the coverage adjustment decision model is trained based on KPI information, and the obtained coverage adjustment decision model is used for subsequent coverage adjustment decisions, and then coverage adjustment is performed based on the coverage adjustment decision model.

[0105] Optionally, the input information of the model is obtained locally from the first network element, and for example, it may include but is not limited to at least one of the following:

[0106] A11. The KPI information of the first network element itself;

[0107] A12. The context information of each connected terminal inside the first network element, especially the quality of service requirements of each service on the terminal;

[0108] A13. The traffic volume information of each data stream of each connected terminal inside the first network element;

[0109] A14. The signal measurement results of each connected terminal inside the first network element for each cell;

[0110] A15. For a certain feasible coverage adjustment behavior, the context information of the affected connected terminals, especially the quality of service requirements of each service on the terminal;

[0111] A16. For a certain feasible coverage adjustment behavior, the traffic volume information of each data stream of the affected connected terminals;

[0112] A17. For a feasible coverage adjustment action, the signal measurement results of the affected connected-mode terminals for each cell;

[0113] A18. The statistic calculated from at least one of the above information according to a given formula, that is, the statistic calculated from at least one of A11 - A17 above according to a given formula;

[0114] For example, for a feasible coverage adjustment action, the sum of the traffic volumes of each data stream weighted by the quality-of-service requirements of each service on the affected connected-mode terminals.

[0115] Method 2: The first network element inputs the obtained KPI information into the coverage adjustment decision model. When it is determined that coverage adjustment is required, the first network element performs the coverage adjustment.

[0116] It should be noted that in this implementation method, the KPI is directly used as the input parameter of the coverage adjustment decision model, that is, the KPI information can directly determine whether to perform coverage adjustment.

[0117] It should be noted that the coverage adjustment decision model is trained based on the KPI information of at least one third network element obtained previously. Optionally, the model acquisition method can be:

[0118] First, for each coverage adjustment action, use the KPI information of the third network element to determine the gain value of the coverage adjustment action. For example, set the gain value of the coverage adjustment to the weighted sum of at least one of the following values:

[0119] A21. The change amount of the KPI information of the first network element before and after the coverage adjustment;

[0120] A22. The change amount of the KPI information of the second network element before and after the coverage adjustment;

[0121] A23. The change amount of the KPI information of the third network element before and after the coverage adjustment;

[0122] A24. The change in the quality of service of the affected terminals during a given time period before and after the coverage adjustment;

[0123] A25. The radio link failure rate of the affected terminals during a given time period before and after the coverage adjustment.

[0124] Then, establish a neural network, use the input information of the model described above as the input of the neural network, and use the above gain value as the output item to be fitted.

[0125] Finally, train the neural network to fit the output item.

[0126] Optionally, the training of the coverage adjustment decision model in the second method may be performed by the first network element, or by the second network element or other network elements; when the second network element or other network elements train the coverage adjustment decision model, after the training of the coverage adjustment decision model is completed, the second network element or other network elements may send the coverage adjustment decision model to the first network element based on the request of the first network element for the first network element to use.

[0127] II. The first network element needs to assist in coverage adjustment based on KPI change information

[0128] It should be noted that when the first network element needs to assist in coverage adjustment based on KPI change information, the second network element may send either KPI information or KPI change information to the first network element; when the first network element obtains KPI change information from the second network element, the first network element may directly assist in coverage adjustment based on the KPI change information; when the first network element obtains KPI information from the second network element, optionally, the method further includes:

[0129] Determine the KPI change information of the third network element according to the KPI information of the third network element in the radio access network.

[0130] That is to say, when the first network element obtains the KPI information of the third network element, it is necessary to first obtain the KPI change information of the third network element based on the KPI information of the third network element, and then perform subsequent coverage adjustment.

[0131] Optionally, the first network element may determine the KPI change information in one of the following ways:

[0132] Method 1: The first network element trains a prediction model based on KPI information, and then inputs the input information of the model into the trained prediction model to obtain the predicted KPI change information. What the input information of the model is specifically has been described above and will not be repeated here.

[0133] It should be noted that in this case, the prediction model is mainly trained based on KPI information, and the obtained prediction model is used to obtain KPI change information.

[0134] Method 2: The first network element inputs the obtained KPI information into the prediction model to obtain the predicted KPI change information.

[0135] It should be noted that the prediction model is trained based on the KPI information of at least one previous third network element. Optionally, the way to obtain the prediction model may be:

[0136] For each coverage adjustment behavior, set the gain value of the coverage adjustment to:

[0137] The change amount of the KPI information of the third network element before and after coverage adjustment;

[0138] Then, a neural network is established, and the input information of the model described above is used as the input of the neural network, and the above gain value is used as the output item to be fitted.

[0139] Finally, the neural network is trained to fit the output item.

[0140] Optionally, the training of the prediction model can be performed by the first network element or the second network element; when the second network element trains the prediction model, after the prediction model is trained, the second network element can send the prediction model to the first network element based on the request of the first network element for the first network element to use.

[0141] Further, it should be noted that when the first network element obtains the predicted KPI change information, the following method can be used for coverage adjustment:

[0142] The first network element substitutes the predicted KPI change information into the decision function, and when it is determined that coverage adjustment is required, the first network element performs coverage adjustment.

[0143] For example, the decision function can be the weighted sum of at least one of the following values for a feasible coverage adjustment behavior:

[0144] A31. The change amount of the predicted KPI information of the first network element before and after coverage adjustment;

[0145] A32. The change amount of the predicted KPI information of the second network element before and after coverage adjustment;

[0146] A33. The change amount of the predicted KPI information of the third network element before and after coverage adjustment;

[0147] A34. The change situation of the predicted service quality of the affected terminals within a given time period before and after coverage adjustment;

[0148] A35. The predicted radio link failure rate of the affected terminals within a given time period before and after coverage adjustment.

[0149] Optionally, the KPI-related information can be obtained based on a request. Specifically, the implementation method of receiving the key performance indicator (KPI)-related information of the third network element in the radio access network sent by the second network element in the radio access network includes:

[0150] Sending a first request message to the second network element, where the first request message is used to request to obtain the KPI-related information of the third network element;

[0151] Receiving the KPI-related information of the third network element in the radio access network sent by the second network element.

[0152] Optionally, in one implementation, the first request message includes at least one of the following:

[0153] B11. Category information of KPIs;

[0154] It should be noted that this category information is used to indicate the required KPI category. For example, the indicated KPI category may include but is not limited to at least one of the following: the category that only requests to provide the total utilization rate of downlink physical resource blocks, the category that only requests to provide the NG-RAN handover success rate, the category that requests to provide both the total utilization rate of downlink physical resource blocks and the NG-RAN handover success rate;

[0155] B12. Provision period of KPI-related information;

[0156] B13. Provision scope of KPI-related information;

[0157] For example, this provision scope indicates that only the total utilization rate of downlink physical resource blocks of a part of cells needs to be provided, and the total utilization rate of downlink physical resource blocks of other cells does not need to be provided.

[0158] B14. Provision conditions of KPI-related information.

[0159] It should be noted that when the second network element receives the first request message from the first network element, if it has the latest KPI-related information itself, it can directly send this information to the first network element; otherwise, the second network element can also obtain KPI information from the third network element based on a request. Optionally, the implementation methods include:

[0160] Sending a second request message to the third network element, where the second request message is used to request the KPI information of the third network element;

[0161] Receiving the KPI information sent by the third network element.

[0162] Optionally, in one implementation, the second request message includes at least one of the following:

[0163] Category information of KPIs, provision period of KPI information, provision scope of KPI information, provision conditions of KPI information.

[0164] It should be noted that since the third network element sends KPI information to the second network element, when the second network element needs to send KPI change information to the first network element, the second network element can also obtain KPI change information in the same way as the first network element obtains KPI change information.

[0165] It should be noted that, based on the method of obtaining KPI-related information upon request, it is possible to avoid other network elements blindly providing KPI information to the CU and the CU blindly providing KPI-related information to the DU, resulting in waste of resources. The recipient of the KPI information sends a request to the provider of the KPI information in advance, and the provider of the KPI information provides the KPI information to the recipient of the KPI information according to the content of the request, which can ensure the effectiveness and timeliness of information transmission.

[0166] The following is an example of the specific application of the embodiments of the present application as follows.

[0167] Application Case 1: The DU trains and uses a coverage adjustment decision model in a manner similar to reinforcement learning as Figure 3 shown. The specific implementation process includes:

[0168] Step 31: Other network elements in the RAN (which can be other RAN nodes or other DUs subordinate to the CU, and the same applies hereinafter and will not be repeated) send an interface message to the CU, which carries KPI information;

[0169] Optionally, the KPI information at this time can be understood as the KPI information before coverage adjustment.

[0170] Step 32: The CU sends the KPI information of other network elements in the RAN mentioned in Step 31 to the DU.

[0171] Step 33: The DU triggers coverage adjustment;

[0172] It should be noted that if there is a coverage adjustment decision model being trained or already trained in the DU, the KPI information of other network elements in the RAN mentioned in Step 32 is an input parameter for the DU to decide whether to trigger coverage adjustment.

[0173] Optionally, when making a coverage adjustment decision, other decision parameters (i.e., the input information of the above-mentioned model) can also be used to assist in making the coverage adjustment decision.

[0174] Step 34: Other network elements in the RAN send an interface message to the CU, which carries the KPI information after coverage adjustment. If there is a coverage adjustment decision model being trained in the DU, then Step 34 must be executed. If there is a coverage adjustment decision model that has been trained in the DU, then Step 34 can either be executed or not.

[0175] Step 35: The CU sends the KPI information of other network elements in the RAN mentioned in Step 34 to the DU.

[0176] Step 36: The DU uses the KPI information after coverage adjustment received in Step 35 to train or adjust the coverage adjustment decision model.

[0177] It should be noted that the training or adjustment mentioned here can be completed by the DU itself or can be requested by the DU for other network elements to execute on its behalf, and no limitation is made here.

[0178] Application Scenario 2: The DU predicts the KPI changes of other network elements before and after coverage adjustment.

[0179] As Figure 4 shown, the specific implementation process includes:

[0180] Step 41: Other network elements in the RAN send an interface message to the CU, carrying KPI information;

[0181] Optionally, the KPI information at this time can be understood as the KPI information before coverage adjustment.

[0182] Step 42: The CU sends the KPI information of other network elements in the RAN mentioned in Step 41 to the DU.

[0183] Step 43: The DU obtains KPI change information based on the KPI information;

[0184] It should be noted that if there is a trained prediction model in the DU, and this prediction model can predict the KPI changes of other network elements before and after coverage adjustment, then the DU executes the prediction based on this prediction model to obtain the predicted KPI change information.

[0185] It should be noted that the specific form of the KPI changes of other network elements is not limited here. Typical examples include the absolute value of the KPI after (predicted) coverage adjustment, the change amount of the KPI after (predicted) coverage adjustment relative to that before coverage adjustment, and an array combining any one of the above two with the absolute value of the KPI before coverage adjustment. Optionally, the KPI information before coverage adjustment received by the DU in Step 42 is an input parameter for it to execute the prediction.

[0186] Step 44: The DU triggers coverage adjustment.

[0187] If the DU executes Step 43, then the prediction result output by Step 43 is an input parameter for the DU to decide whether to trigger coverage adjustment.

[0188] Step 45. Other network elements in the RAN send an interface message to the CU, carrying the KPI information after coverage adjustment. If there is a prediction model being trained inside the DU, then Step 45 must be executed. If there is a prediction model that has been trained inside the DU, then Step 45 can either be executed or not.

[0189] Step 46. The CU sends the KPI information of other network elements in the RAN mentioned in Step 45 to the DU.

[0190] Step 47. The DU uses the KPI information after coverage adjustment it received in Step 45 to train or adjust the prediction model mentioned in Step 43. This step can occur either when the training module is training or when the prediction model has been trained.

[0191] It should be noted that the training or adjustment mentioned here can be completed by the DU itself or can be requested by the DU for other network elements to execute on its behalf, which is not limited here.

[0192] Application Case 3. The CU predicts the KPI changes of other network elements before and after coverage adjustment

[0193] As Figure 5 shown, the specific implementation process includes:

[0194] Step 51. Other network elements in the RAN send an interface message to the CU, carrying the KPI information;

[0195] Optionally, the KPI information at this time can be understood as the KPI information before coverage adjustment.

[0196] Step 52. The CU obtains the KPI change information based on the KPI information.

[0197] It should be noted that if there is a prediction model that has been trained inside the CU and this prediction model can predict the KPI changes of other network elements before and after coverage adjustment, then the CU executes the prediction based on this prediction model to obtain the prediction result, that is, the predicted KPI change information.

[0198] It should be noted that the specific form of the KPI changes of other network elements is not limited here. Typical examples include the absolute value of the KPI after (predicted) coverage adjustment, the change amount of the KPI after (predicted) coverage adjustment relative to that before coverage adjustment, and an array combining any one of the above two with the absolute value of the KPI before coverage adjustment. Optionally, the KPI information before coverage adjustment received by the CU in Step 51 is an input parameter for it to execute the prediction.

[0199] Step 53: The CU sends the prediction result output in Step 52 to the DU.

[0200] Step 54: The DU triggers coverage adjustment.

[0201] If Steps 52 and 53 are executed, then the prediction result received by the DU through Step 53 is an input parameter for the DU to determine whether to trigger coverage adjustment.

[0202] Step 55: Other network elements in the RAN send an interface message to the CU, carrying the KPI information after coverage adjustment. If there is a prediction model being trained inside the CU, then Step 55 must be executed. If there is a prediction model that has been trained inside the CU, then Step 55 can either be executed or not be executed.

[0203] Step 56: The CU uses the KPI information after coverage adjustment that it received in Step 55 to train or adjust the prediction model mentioned in Step 53. This step can occur either when the prediction model is being trained or when the prediction model has been trained.

[0204] It should be noted that the training or adjustment mentioned here can be completed by the CU itself internally, or it can be requested by the CU for other network elements to execute on its behalf. This is not limited here.

[0205] It should be noted that the implementation method provided in the embodiments of this application enables the DU to directly or indirectly refer to the impact of past adjustments on other radio access network elements when performing coverage adjustment in the CU / DU split scenario, improving the overall performance of the system.
