Description

Technical Field

[0001] The present application relates to the field of wireless communication technologies, and in particular, to a method and apparatus for wireless slice configuration, a computer device, a storage medium, and a computer program product. Background Art

[0002] With the development of wireless communication technologies, a method has emerged that combines the communication service management function (CSMF), the slice management function (NSMF), and the sub-slice management function (NSSMF) to manage 5G network slices from the management domain. Currently, to meet the requirements for dedicated network service provisioning and resource guarantee, it is usually necessary to perform refined exclusive configuration of resources including RBs for wireless slices.

[0003] Currently, the configuration entities for resource configuration of wireless slices are usually the NR cell DU and the NR cell CU, and the operation object is the slice set. However, this configuration method is inconsistent with the wireless slice management interface that uses the slice identifier as the operation object and is difficult to match. At the same time, the wireless slice management interface does not have the ability to perform accurate cell-level configuration of exclusive resources for wireless slices, and it is impossible to implement configuration adjustment of exclusive resources for wireless slices at the cell level. Therefore, in the existing wireless slice configuration methods, the slice management domain does not have the ability to perform fine-grained, i.e., cell-level, resource configuration for wireless slices.

[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The wireless slice configuration method provided by the embodiments of the present application can be applied to, for example Figure 1In the application environment shown. Among them, the slice configuration function operation and management terminal 101 communicates with the network element unified management platform 102, that is, the OMC-R terminal, through the network. Specifically, after the slice configuration function operation and management terminal 101 determines the target cell that needs to perform wireless slice configuration, it can also obtain the network element configuration data and cell resource configuration strategy of the target cell. After that, if the wireless slice management interface associated with the network element unified management platform 102 corresponding to the target cell is the target management interface using the NSMF to AN-NSSMF interface, the cell structure of the sub-slice instance signaling set of the target management interface can be enhanced to obtain the first signaling enhanced interface. If the associated wireless slice management interface does not use the above-mentioned NSMF to AN-NSSMF interface target management interface, the signaling set of the wireless slice management interface is enhanced to obtain the second signaling enhanced interface. Finally, the enhanced signaling in the above-mentioned signaling enhanced interface can be filled by using the network element configuration data and cell resource configuration strategy corresponding to the target cell, and at the same time, the above-mentioned first signaling enhanced interface or the second signaling enhanced interface is called to send the filled signaling to the network element unified management platform 102, so that the network element unified management platform 102 can perform wireless slice configuration on the target cell according to the filled signaling. Among them, both the slice configuration function operation and management terminal 101 and the network element unified management platform 102 can be implemented by an independent server or a server cluster composed of multiple servers.

[0051] In one embodiment, as Figure 2 shown, a wireless slice configuration method is provided. Taking the slice configuration function operation and management terminal 101 applied to Figure 1 as an example, the method includes the following steps:

[0052] Step S201, obtain the target cell of the wireless slice to be configured and the network element configuration data and cell resource configuration strategy for the target cell.

[0053] Among them, the target cell refers to the network element cell that needs to perform wireless slice configuration. The determination of the target cell can be based on the wireless slice configuration requirement. The network element configuration data refers to the configuration data of the network element corresponding to the target cell, and the cell resource configuration strategy refers to the configuration strategy for performing wireless slice configuration on the target cell. Specifically, the slice configuration function operation and management terminal 101 can first determine the target cell that needs to perform wireless slice configuration, and obtain the network element configuration data for the target cell, as well as the cell resource configuration strategy for performing wireless slice configuration on the target cell.

[0054] Step S202, when the radio slice management interface associated with the network element unified management platform 102 corresponding to the target cell is the target management interface, perform cell structure enhancement on the sub-slice instance signaling set of the target management interface to obtain a first signaling enhanced interface; the target management interface is the NSMF-to-AN-NSSMF interface.

[0055] The target signaling interface refers to the radio slice management interface using the NSMF-to-AN-NSSMF interface. This radio slice management interface can be the radio slice management interface associated with the network element unified management platform 102. The network element unified management platform 102 can receive control signaling for radio slice configuration of the target cell from the slice configuration function operation and management end 101 by calling the associated radio slice management interface to implement radio slice configuration for the target cell.

[0056] Specifically, if the radio slice management interface associated with the network element unified management platform corresponding to the target cell is in the case of using the NSMF-to-AN-NSSMF interface, the slice configuration function operation and management end 101 can also first perform cell structure enhancement on the sub-slice instance signaling set of the target management interface, thereby obtaining the radio slice management interface after signaling enhancement, that is, the first signaling enhanced interface.

[0057] Step S203, when the radio slice management interface does not use the target management interface, perform signaling set enhancement on the radio slice management interface to obtain a second signaling enhanced interface.

[0058] If the radio slice management interface is not in the case of using the NSMF-to-AN-NSSMF interface, then the slice configuration function operation and management end 101 can perform signaling set enhancement processing on the radio slice management interface, thereby also obtaining the radio slice management interface after signaling enhancement, that is, the second signaling enhanced interface.

[0059] Step S204, use the network element configuration data corresponding to the target cell and the cell resource configuration policy to fill the enhanced signaling in the signaling enhanced interface, and call the first signaling enhanced interface or the second signaling enhanced interface to send the filled signaling to the network element unified management platform 102, so that the network element unified management platform 102 performs radio slice configuration on the target cell according to the filled signaling.

[0060] After obtaining the signaling enhancement interfaces corresponding to two different radio slice management interfaces in step S202 and step S203, the slice configuration function operation and management end 101 can further use the network element configuration data and the cell resource configuration policy to fill the enhanced signaling in the above-mentioned first signaling enhancement interface or the second signaling enhancement interface to obtain the filled signaling. After that, by calling the above-mentioned first signaling enhancement interface or the second signaling enhancement interface, the filled signaling can be sent to the corresponding network element unified management platform 102 through the above-mentioned first signaling enhancement interface or the second signaling enhancement interface. Then, the network element unified management platform 102 can implement the radio slice configuration of the target cell according to the received filled signaling. For example, the network element unified management platform 102, that is, the OMC-R end, can parse the above-mentioned filled signaling, issue commands to the corresponding network elements for execution, and then the network elements can implement the radio slice configuration of the corresponding target cell based on the parsing results.

[0061] In the above radio slice configuration method, the slice configuration function operation and management end 101 obtains the target cell of the radio slice to be configured and the network element configuration data and the cell resource configuration policy for the target cell; when the radio slice management interface associated with the network element unified management platform 102 corresponding to the target cell is the target management interface, the signaling cell structure of the sub-slice instance signaling set of the target management interface is enhanced to obtain the first signaling enhancement interface; the target management interface is the NSMF to AN-NSSMF interface; when the radio slice management interface does not adopt the target management interface, the signaling set of the radio slice management interface is enhanced to obtain the second signaling enhancement interface; the enhanced signaling in the signaling enhancement interface is filled by using the network element configuration data and the cell resource configuration policy corresponding to the target cell, and the first signaling enhancement interface or the second signaling enhancement interface is called to send the filled signaling to the network element unified management platform 102, so that the network element unified management platform 102 can perform radio slice configuration on the target cell according to the filled signaling. In this application, the slice configuration function operation and management end can obtain the network element configuration data and the cell resource configuration policy of the target cell of the radio slice to be configured, and can also enhance the signaling of the radio slice management interface associated with the network element unified management platform corresponding to the target cell, so as to fill the enhanced signaling by using the network element configuration data and the cell resource configuration policy, and send the filled enhanced information to the network element unified management platform 102 by calling the signaling enhancement interface, so as to implement the radio slice configuration of the target cell. Through this method, the radio slice configuration at the cell granularity can be realized, thereby improving the fineness of the radio slice configuration.

[0062] In one embodiment, step S202 may further include: obtaining the transfer signaling included in the sub-slice instance signaling set; creating a radio slice resource configuration structure for the RANSliceSubnetProfile in the SliceProfile structure of the transfer signaling to enhance the transfer signaling.

[0063] The transfer signaling refers to the signaling used for transfer in the sub-slice instance signaling set. The transfer signaling can be composed of multiple signaling structures. The SliceProfile structure is a part of the above-mentioned multiple signaling structures, and the SliceProfile structure may also include RANSliceSubnetProfile. In this embodiment, the process of enhancing the cell structure of the sub-slice instance signaling set can be to create a radio slice resource configuration structure for the RANSliceSubnetProfile in the SliceProfile structure of the transfer signaling in the sub-slice instance signaling set, that is, adding a radio slice resource configuration structure to the existing transfer signaling in the sub-slice instance signaling set to achieve the enhancement of the transfer signaling.

[0064] Among them, the enhanced structure may include cell unique identifier, slice set identifier, slice and slice set mapping operation (binding / unbinding), slice set resource configuration type, dedicated ratio of home slice set resource configuration, minimum ratio, maximum ratio, etc.; the resource configuration type includes RB uplink and downlink resources, RRC connection resources, etc. By creating the above data structures in the RANSliceSubnetProfile of the SliceProfile structure of the transfer signaling, the transfer signaling is enhanced.

[0065] In this embodiment, the method for enhancing the cell structure of the sub-slice instance signaling set can be achieved by creating a radio slice resource configuration structure for the RANSliceSubnetProfile in the SliceProfile structure of the transfer signaling. Through this method, signaling enhancement for the NSMF to AN-NSSMF interface of the radio slice management interface can be achieved, thereby ensuring cell-level resource configuration for the target management interface.

[0066] In addition, step S103 may further include: creating a radio slice resource configuration signaling set in the signaling set corresponding to the radio slice management interface; where the structure of the radio slice resource configuration signaling set uses the slice set list as the operation object, and the radio slice resource configuration signaling set is set with the mapping binding of the slice set to the activated slices.

[0067] For a non-target management interface, that is, a radio slice management interface that does not adopt the NSMF-to-AN-NSSMF interface, in order to implement cell-level resource configuration, the signaling enhancement method for the radio slice management interface in this embodiment is different from that for the target management interface. It is achieved by further creating a signaling set for implementing radio slice resource configuration in the signaling set corresponding to the radio slice management interface. And the structure of this signaling set mainly takes the slice set list as the operation object, and can also complete the mapping and binding of the slice set to the activated slices.

[0068] Specifically, the feedback structures of the created enhanced signaling set, update, allocation / de-allocation signaling, and status detection signaling include cell resource object type, cell resource object unique identifier, and slice set list. The slice set list contains N slice set structures; the slice set structure includes the identifier of the slice set, the slice set and slice mapping and binding relationship structure, slice set resource configuration type, slice set resource configuration dedicated ratio, minimum ratio, maximum ratio, etc.; among them, the cell resource object is the cell resource object to which the slice set list belongs. The cell resource object type may include: cell CU, cell DU, etc. The slice set resource configuration type may include RB uplink and downlink resources, RRC connection resources, etc. The slice set and slice mapping and binding relationship structure is a 1:N relationship.

[0069] In this embodiment, the method for implementing signaling set enhancement for the radio slice management interface may be to create a radio slice resource configuration signaling set in the signaling set corresponding to the radio slice management interface. And the structure of this radio slice resource configuration signaling set mainly takes the slice set list as the operation object, and can also complete the mapping and binding of the slice set to the activated slices. Through this setting, the radio slice management interface can be updated from the original operation object of S-NSSAI (slice identifier) to the operation object of the slice set defined by the existing standard, so as to ensure cell-level resource configuration for the non-target management interface.

[0070] In one embodiment, as Figure 3 shown, step S201 may further include:

[0071] Step S301, receiving a radio slice configuration request sent by the NSMF, parsing the radio slice configuration request, and obtaining the radio slice resource configuration area range of the radio slice configuration request.

[0072] The radio slice configuration request is a request for requesting radio slice configuration for the target cell. For example, it can be a radio slice configuration intention and radio slice configuration requirements, etc. This request can be sent by the NSMF to the slice configuration function operation management terminal 101, and the radio slice resource configuration area range refers to the radio slice configuration range represented in the radio slice configuration request.

[0073] Specifically, a user who needs to perform a wireless slice configuration service can first initiate a service activation intention to the CSMF. After receiving the above service activation intention, the CSMF can translate the service activation intention into slice intentions and requirements and send them to the NSMF. Then, based on the slice intentions and requirements obtained after the above translation, the NSMF can further generate wireless slice configuration intentions and requirements, and send them as a wireless slice configuration request to the slice configuration function operation and management end 101. After receiving the above wireless slice configuration request, the slice configuration function operation and management end 101 can parse the wireless slice configuration request to obtain the corresponding wireless slice resource configuration area range.

[0074] Step S302: According to the wireless slice resource configuration area range and the cell coverage ranges of each pre-determined candidate cell, determine the cells associated with the wireless slice resource configuration area range from the candidate cells as target cells.

[0075] A candidate cell can refer to a cell that may be selected as the target cell for which wireless slice configuration is required. The cell coverage range refers to the cell coverage area corresponding to each candidate cell generated by statistical operations on the wireless network operation system. Specifically, after determining the wireless slice resource configuration area range, the slice configuration function operation and management end 101 can use the cell coverage ranges of each candidate cell to screen out the cells associated with the wireless slice resource configuration area range from the candidate cells as target cells. For example, it can generate a map polygon according to the service slice resource configuration range and match it with the cell coverage areas of each candidate cell generated by statistical operations on the wireless network operation system to screen out the target cells for which wireless slice configuration is required from the candidate cells.

[0076] In this embodiment, the determination of the target cells can be obtained from the wireless slice resource configuration area range parsed from the wireless slice configuration request sent by the NSMF and the cell coverage areas of each candidate cell. By this method, the accuracy of target cell screening can be further improved, and the screened target cells can also be adapted to the wireless slice configuration request.

[0077] Furthermore, after step S301, service guarantee information corresponding to the wireless slice configuration request can also be obtained; as Figure 4 shown, step S101 can further include:

[0078] Step S401: Monitor the status of each target cell and obtain the cell status monitoring data corresponding to each target cell.

[0079] Service guarantee information refers to the service basic information corresponding to the wireless slice configuration request. For example, it may include information such as the uplink user guarantee rate, downlink user guarantee rate, number of users, user density, etc. corresponding to the wireless slice configuration request. The cell status monitoring data may refer to the monitoring data obtained by monitoring the status of the target cell. The monitoring data may include the key configuration information of the target cell, key network operation and service data, etc. Among them, the key configuration information may include the frequency band, system type, time slot ratio, time slot structure, bandwidth, number of channels, etc. adopted by the cell; the key network operation data includes the traffic data of the countable network level at different time granularities in the cell history, the number of PRB resources occupied, the PRB resource utilization rate, the maximum number of RRC connected users, the average number of RRC connected users, etc.; the service data may include the traffic differentiated by service, the slice usage status, etc.

[0080] Specifically, after determining the target cell, the slice configuration function operation management end 101 can first obtain the status monitoring data corresponding to each target cell by monitoring the status of the target cell.

[0081] Step S402: Generate the initial cell resource configuration strategy corresponding to each target cell by using the cell status monitoring data and the service guarantee information.

[0082] After obtaining the status monitoring data and service guarantee information of each cell, the initial cell resource configuration strategy corresponding to each target cell can be generated by using the cell status monitoring data and the service guarantee information. For example, the generation of the initial cell resource configuration strategy can be achieved through an AI algorithm. That is, the wireless slice resource configuration of the target cell can be evaluated and predicted through algorithms such as AI. For example, the uplink and downlink user rates to be guaranteed in each cell can be calculated based on the user density and cell status data, and the slice resource configuration of each cell under the configuration intention and requirements of the wireless slice can be evaluated and predicted by combining the key configuration information of the cell and the network operation data, so as to generate the resource configuration strategy at the cell granularity.

[0083] Step S403: Obtain the cell resource configuration strategy corresponding to each target cell based on each initial cell resource configuration strategy.

[0084] In order to ensure the accuracy of the generated initial cell resource configuration strategy, after obtaining the initial cell resource configuration strategy corresponding to each target cell, this application also needs to verify each of the above initial cell resource configuration strategies. Only when the verification is passed, will the slice configuration function operation management end 101 use the determined initial cell resource configuration strategy corresponding to each target cell as the final cell resource configuration strategy for each target cell.

[0085] In this embodiment, after parsing the wireless slice configuration request, the slice configuration function operation management terminal 101 can also obtain the service guarantee information corresponding to the wireless slice configuration request, and can also generate the initial cell resource configuration strategy corresponding to each target cell based on the cell status monitoring data obtained by monitoring the status of the target cell and the above service guarantee information, and then obtain the cell resource configuration strategy corresponding to each target cell. In this way, the accuracy of the determined cell resource configuration strategy can be further improved.

[0086] Further, as Figure 5 shown, step S403 may further include:

[0087] Step S501, according to the initial cell resource configuration strategy corresponding to each target cell, obtain the additional cell resource load corresponding to each target cell for the initial cell resource configuration strategy.

[0088] The additional cell resource load refers to the cell resource load caused by the initial cell resource configuration strategy. Since a new wireless slice service needs to be enabled in the target cell, the cell resource load of the target cell will inevitably increase. As for how much the cell resource load increases, it is determined based on the cell resource configuration strategy corresponding to the target cell. After obtaining the initial cell resource configuration strategy of each target cell, the slice configuration function operation management terminal 101 can also determine the additional cell resource load corresponding to each initial cell resource configuration strategy according to the above initial cell resource configuration strategy.

[0089] Step S502, based on the cell status monitoring data corresponding to each target cell, obtain the current cell resource load corresponding to each target cell.

[0090] The current cell resource load refers to the current cell resource load of each target cell before the new wireless slice service is enabled. This cell resource load can be monitored based on the cell status monitoring data corresponding to each target cell. Specifically, after obtaining the cell status monitoring data corresponding to each target cell, the slice configuration function operation management terminal 101 can also obtain the current cell resource load of each target cell based on the above cell status monitoring data.

[0091] Step S503, if the superimposed load of each additional cell resource load and the current cell resource load meets the service load threshold of each target cell, then use each initial cell resource configuration strategy as the cell resource configuration strategy corresponding to each target cell.

[0092] The superimposed load is the cell resource load after superimposing the new cell resource load and the current cell resource load of the cell. The service load threshold can be used to characterize the cell service load capacity. If the superimposed load of each target cell can meet the service load threshold of the target cell, that is, the superimposed load of each target cell can meet the cell service load capacity, then the slice configuration function operation and management end 101 can use each initial cell resource configuration strategy as the final cell resource configuration strategy for each target cell.

[0093] In this embodiment, the slice configuration function operation and management end 101 can also determine whether the superimposed cell resource load meets the cell service load capacity of each target cell based on the cell resource load corresponding to the initial cell resource configuration strategy and the current cell resource load of each target cell. If so, it uses the initial cell resource configuration strategy of each target cell as the final cell resource configuration strategy for the target cell. In this way, it can be ensured that the cell resource configuration strategy of each target cell can meet the cell service load capacity, and the rationality of the cell resource configuration strategy can be further improved.

[0094] In addition, as Figure 6 shown, after step S502, it may further include:

[0095] Step S601, if the superimposed load of the new cell resource load and the current cell resource load of a target cell exceeds the service load threshold of the target cell, then the target cell is regarded as a cell to be adjusted, and the resource configuration analysis result corresponding to the cell to be adjusted is obtained.

[0096] The cell to be adjusted refers to the cell in the target cells that needs to have its resource configuration adjusted. If the superimposed load of a certain target cell exceeds the service load threshold of the target cell, that is, when the superimposed load exceeds the cell service load capacity, the slice configuration function operation and management end 101 can regard the target cell as the cell to be adjusted and obtain the resource configuration analysis result corresponding to the cell to be adjusted. For example, it can be the above-mentioned root cause analysis result of the problem corresponding to the cell to be adjusted. The above-mentioned root cause analysis result of the problem can also be obtained based on the cell status monitoring data and service guarantee information of the cell to be adjusted. In this embodiment, if the superimposed load of the target cell exceeds the cell service load capacity of the cell, the slice configuration function operation and management end 101 can further generate the root cause analysis result of the problem corresponding to the cell to be adjusted as the resource configuration analysis result corresponding to the cell to be adjusted while generating the initial cell resource configuration strategy using the AI algorithm.

[0097] Step S602, send the resource configuration analysis result to the RAN planning, construction, maintenance, and optimization system, and obtain the target cell after the RAN planning, construction, maintenance, and optimization system adjusts the resource configuration of the cell to be adjusted based on the resource configuration analysis result.

[0098] The RAN planning, construction, maintenance, and optimization system is used to adjust the resource configuration of the cell to be adjusted to solve the resource load problem of the cell to be adjusted. The adjustment method can be to adjust the cell to be adjusted through means such as maintenance, optimization, and expansion to solve the above resource load problem. Specifically, after the slice configuration function operation management terminal 101 determines the resource configuration analysis result corresponding to each cell to be adjusted, it can also send the above resource configuration analysis result to the RAN planning, construction, maintenance, and optimization system. The RAN planning, construction, maintenance, and optimization system can then adjust the resource configuration of the cell to be adjusted based on the resource configuration analysis result. For example, through means such as maintenance, optimization, and expansion, to solve the above resource load problem, thereby obtaining the target cell after the resource configuration of each cell to be adjusted is adjusted.

[0099] Step S603: Use the adjusted target cell as the new target cell, and return to execute step S402 until the superimposed load of the resource loads of the newly added cells and the current cell resources of each target cell meets the service load threshold of each target cell.

[0100] After obtaining the adjusted target cell, the slice configuration function operation management terminal 101 can also use the adjusted target cell as the new target cell and return to execute step S402 to generate a new initial cell resource configuration strategy again until the superimposed load of the resource loads of the newly added cells and the current cell resources of all target cells meets the service load threshold of each target cell, that is, until it meets the corresponding cell service load capacity of the target cell.

[0101] In this embodiment, if there is a target cell whose superimposed load exceeds the cell service load capacity, the resource configuration analysis result corresponding to the cell can also be obtained, so as to adjust the resource configuration of the cell through the RAN planning, construction, maintenance, and optimization system to ensure the rationality of the cell resource configuration.

[0102] In one embodiment, a wireless slice configuration method is also provided to achieve precise configuration adjustment of wireless slice resources, such as Figure 7 shown. This method may include the following steps:

[0103] Step 1: The CSMF receives the vertical industry service activation intention and translates it into a slice intention and requirements, which are then passed to the NSMF. The NSMF further generates a wireless slice configuration intention and requirements and sends them to the wireless slice configuration function operation management terminal;

[0104] Step 2: The operation and management end of the wireless slice configuration function receives the wireless slice configuration intention and requirements, parses and generates the wireless slice resource configuration area scope, network element and service guarantee information, etc. Then, it detects the status of the target network elements for the wireless slice configuration, and obtains the key configuration information, key network operation and service data of the target network elements;

[0105] Step 3: Based on the obtained network element status data, use algorithms such as AI to evaluate and predict the resource usage of the target network elements for the wireless slice configuration, generate a resource configuration strategy at the cell granularity, and form the network element cells that do not meet the configuration requirements and the corresponding root cause analysis information of the problems;

[0106] Step 4: Determine whether there are network element cells that do not meet the configuration requirements. If so, jump to Step 5; otherwise, jump to Step 6;

[0107] Step 5: Notify the RAN planning, construction, maintenance and optimization system, NSMF / CSMF of the network element cells that do not meet the configuration requirements and the corresponding root cause analysis information of the problems; The RAN planning, construction, maintenance and optimization system solves the problems of the network element cells that do not meet the configuration requirements. And feedback the result of the target network elements for the wireless slice configuration to the operation and management end of the wireless slice configuration function. Then jump to Step 3;

[0108] Step 6: Determine whether the NSMF to AN-NSSMF interface is adopted for the wireless slice management interface. If so, jump to Step 7; otherwise, jump to Step 8;

[0109] Step 7: The operation and management end of the wireless slice configuration function enhances the cell structure of the signaling set of the sub-slice instance in the NSMF to AN-NSSMF interface, and creates a wireless slice resource configuration structure for the RANSliceSubnetProfile in the SliceProfile transmitted therein. Then, fill in the signaling and cell structure information according to the target network element configuration data and the resource configuration strategy at the cell granularity. Then, according to the resource configuration strategy orchestration and combination, call the enhanced interface of the signaling set of the sub-slice instance in the NSMF to AN-NSSMF interface to send the wireless slice resource configuration and adjustment information to the AN-NSSMF of the OMC-R (including network element link establishment and data interaction in the middle). The AN-NSSMF of the OMC-R transmits the enhanced signaling of the sub-slice instance to the OMC-R end of the wireless slice configuration function. After completion, jump to Step 9;

[0110] Step 8: The operation and management end of the wireless slice configuration function enhances the signaling set of the wireless slice management interface, creates a signaling set and structure for wireless slice resource configuration, and completes the mapping and binding of the sliced slice to the slice set. Then, fill in the signaling and cell structure information according to the target network element configuration data and the cell-level resource configuration policy. Orchestrate and combine the enhanced interface of the wireless slice management signaling set according to the resource configuration policy, and send the wireless slice resource configuration and adjustment information to the OMC-R end of the wireless slice configuration function (including network element link establishment and data interaction in the middle);

[0111] Step 9: The OMC-R end of the wireless slice configuration function parses the wireless slice resource configuration and adjustment information, and issues commands to the corresponding network elements for execution. And feedback the execution result to the upper-layer network element through the signaling channel.

[0112] Specifically, the system process of the above wireless slice configuration method may include the following three parts. Figure 8 It is an interaction diagram of System Process 1 of the wireless slice resource configuration method. Figure 9 It is an interaction diagram of System Process 2 of the wireless slice resource configuration method, while Figure 10 It is an interaction diagram of System Process 3 of the wireless slice resource configuration method. The detailed steps of each system process are as follows:

[0113] For System Process 1, as Figure 8 shown, it may include the following steps:

[0114] Step 1: The CSMF receives the vertical industry service activation intention and translates it into a sliced intention and requirements, and passes them to the NSMF;

[0115] Step 2: The NSMF further generates a wireless slice configuration intention and requirements, and sends them to the operation and management end of the wireless slice configuration function;

[0116] Step 3: The operation and management end of the wireless slice configuration function receives the wireless slice configuration intention and requirements and parses them to generate the wireless slice resource configuration area range and service guarantee information (such as uplink user guarantee rate, downlink user guarantee rate, number of users, user density, etc.). Then, match the generated map polygon with the cell coverage area statistically calculated on the wireless network operation system according to the service slice resource configuration range to generate the target cell information;

[0117] Step 4: Then, perform state detection on the target cell for the wireless slice configuration to obtain the key configuration information, key network operation, and service data of the target cell. The key configuration information may include the frequency band, system type, time slot ratio, time slot structure, bandwidth, number of channels, etc. adopted by the cell; the key network operation data includes traffic data at the network layer that can be statistically counted at different time granularities in the cell's history, the number of PRB resources occupied, the PRB resource utilization rate, the maximum number of RRC connected users, the average number of RRC connected users, etc.; the service data may include traffic differentiated by service, slice usage status, etc.

[0118] Step 5: Based on the obtained cell status data and service guarantee information, the operation and management end of the wireless slice configuration function uses algorithms such as AI to evaluate and predict the wireless slice resource configuration of the target cell. For example, based on the user density and cell status data, calculate the uplink and downlink user rates to be guaranteed for each cell, and combine the key configuration information of the cell and the network operation data to evaluate and predict the slice resource configuration of each cell under the configuration intention and requirements of this wireless slice based on the algorithm, so as to generate a resource configuration strategy at the cell granularity.

[0119] Step 6: If the superimposed cell resource load situation exceeds the cell service load capacity, generate the network element cells that do not meet the configuration requirements and the corresponding root cause analysis information of the problems, and notify the RAN planning, construction, maintenance, and optimization system and the NSMF / CSMF. The RAN planning, construction, maintenance, and optimization system solves the problems of the network element cells that do not meet the configuration requirements through means such as maintenance, optimization, and expansion, and feeds back the results.

[0120] Step 7: The operation and management end of the wireless slice configuration function re-evaluates and predicts the wireless slice resource configuration of the corresponding cell of the feedback result to determine whether it meets the slice configuration requirements. If not, jump to Step 6.

[0121] For System Process 2, if the AN-NSSMF is deployed on the OMC-R side and the wireless slice management interface uses the NSMF to AN-NSSMF interface, as Figure 9 shown, the following steps may be included:

[0122] Step 1: The operation and management end of the wireless slice configuration function enhances the cell structure of the signaling set of the sub-slice instance in the NSMF to AN-NSSMF interface, and creates a wireless slice resource configuration structure for the RANSliceSubnetProfile in the transmitted SliceProfile; this enhanced structure includes the cell unique identifier, slice set identifier, slice and slice set mapping operation (binding / unbinding), slice set resource configuration type, dedicated ratio of the belonging slice set resource configuration, minimum ratio, maximum ratio, etc.; among them, the resource configuration type includes RB uplink and downlink resources, RRC connection resources, etc.

[0123] Step 2: The operation and management terminal of the wireless slice configuration function fills in signaling and cell structure information according to the target network element configuration data and the cell granularity resource configuration policy. And it arranges and combines calls to the enhanced signaling set interface of the sub-slice instance in the NSMF to AN-NSSMF interface according to the resource configuration policy;

[0124] Step 3: The NSMF sends the wireless slice resource configuration and adjustment information to the AN-NSSMF of the OMC-R through the enhanced signaling set interface of the sub-slice instance in the NSMF to AN-NSSMF interface, including network element link establishment and data interaction;

[0125] Step 4: The AN-NSSMF of the OMC-R passes the enhanced signaling of the sub-slice instance to the OMC-R side of the wireless slice configuration function;

[0126] Step 5: The OMC-R side of the wireless slice configuration function parses the wireless slice resource configuration and adjustment information, issues commands to the corresponding network elements for execution. And it feedbacks the execution results to the upper-layer network elements through the signaling channel.

[0127] For system process 3, if the wireless slice management interface does not adopt the NSMF to AN-NSSMF interface, as Figure 10 shown, the following steps may be included:

[0128] Step 1: The operation and management terminal of the wireless slice configuration function enhances the signaling set of the wireless slice management interface, creates a wireless slice resource configuration signaling set and structure. This signaling set structure takes the slice set list as the operation object and can complete the mapping and binding of the slice set to the already opened slices. The feedback structure of the updated, allocated / de-allocated signaling and status detection signaling of this enhanced signaling set includes the cell resource object type, the unique identifier of the cell resource object, and the slice set list. The slice set list contains N slice set structures; the slice set structure includes the identifier of the slice set, the slice set and slice mapping and binding relationship structure, the slice set resource configuration type, the dedicated ratio of the slice set resource configuration, the minimum ratio, the maximum ratio, etc.; among them, the cell resource object is the cell resource object to which the slice set list belongs. The cell resource object type may include: cell CU, cell DU, etc. The slice set resource configuration type may include RB uplink and downlink resources, RRC connection resources, etc. The slice set and slice mapping and binding relationship structure is a 1:N relationship;

[0129] Step 2: The operation and management terminal of the wireless slice configuration function fills in signaling and cell structure information according to the target network element configuration data and the cell granularity resource configuration policy. It arranges and combines calls to the enhanced signaling set interface of the wireless slice management according to the resource configuration policy, and sends the wireless slice resource configuration and adjustment information to the OMC-R side of the wireless slice configuration function (including network element link establishment and data interaction in the middle);

[0130] Step 3: The OMC-R end of the wireless slice configuration function parses the wireless slice resource configuration and adjustment information, issues commands to the corresponding network elements for execution, and feeds back the execution results to the upper-layer network elements through the signaling channel.

[0131] In the above embodiments, for different deployment scenarios of slice management functions, when the AN-NSSMF is deployed on the OMC-R side and the wireless slice management interface uses the NSMF to AN-NSSMF interface, the RANSliceSubnetProfile in the SliceProfile for signaling process transmission of sub-slice instances is structurally enhanced; when the wireless slice management interface does not use the NSMF to AN-NSSMF interface, the signaling set structure of the wireless slice management interface is enhanced to implement the mapping and binding of slices to slice sets and the ability to configure and adjust slice set resources. And on the basis of the above method, the global function support of the slice management domain for resource configuration is further realized. Thus, on the basis of effectively adapting to the existing system interfaces and the already launched wireless slice services, the demand for accurate resource configuration and adjustment of private network services at the front end is met, and the digital ability and automation level of wireless network operation are effectively improved.
