Description

Technical Field

[0001] This application relates to the field of network technologies, and in particular, to a 5G network slice service control method, apparatus, system, and storage medium. Background Art

[0002] Network slicing is one of the characteristic functions of 5G networks. By means of network slicing, operators can change the network operation mode of "one-size-fits-all" and "best-effort" for all types of services in the past, and can provide personalized and guaranteed network services for customers.

[0003] In the existing operator's live network, for the slice management of the radio access network, it is completed by the interaction between the Network Slice Management Function (NMSF) and the Operation & Maintenance Center Radio (OMCR) of the 5G radio subsystems in all provinces across the country, that is, the Access Network - Network Slice Subnet Management Function (AN-NSSMF). First, the management of slice application requirements is completed through the Communication Service Management Function (CSMF); then, the cross-domain slice management is completed through the NMSF; finally, the slice management of the radio access network is implemented through the AN-NSSMF. Among them, the CSMF and NMSF are centrally managed by the group side, and the AN-NSSMF function is implemented by the OMCR of the 5G radio network in each province.

[0004] However, this decentralized mode places too high requirements on the NMSF. Any addition or deletion of the OMCR of the radio subsystems in each province requires relevant cooperation operations from the NSMF, and it cannot meet the differentiated and personalized requirements for slice applications in different regions. Summary of the Invention

Further, slice parameter data corresponding to each access network network sub-slice management function network element AN-NSSMF within the connected area range is collected, and the same target slice parameters and slice granularity in the implementation manner of the slice application are determined for each AN-NSSMF within the area range.

These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0059] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0060] In the existing operator's live network, the slice management of the radio access network is completed through the interaction between the Network Slice Service Management Function (NMSF) and the Operation and Maintenance Center (OMCR) of the 5G radio subsystems in all provinces across the country, that is, the Access Network Network Sub-Slice Management Function (AN-NSSMF). First, the management of slice application requirements is completed through the Communication Service Management Function (CSMF); then, cross-domain slice management is completed through the NMSF; finally, the slice management of the radio access network is realized through the AN-NSSMF. Among them, the CSMF and the NMSF are centrally managed by the group side, and the function of the AN-NSSMF is implemented by the OMCR of the 5G radio network in each province. However, this decentralized mode places too high requirements on the NMSF. Any addition or deletion of the OMCR of the radio subsystems in each province requires relevant cooperation operations from the NMSF, and it cannot meet the differentiated and personalized requirements for slice applications in different regions.

[0061] This application receives the operation request of the slice application sent by the NMSF or input by the user from the AN UI-NSSMF interface of the access network centralized network sub-slice management function, and determines the implementation method of the slice application for the operation request of the slice application according to the operation request of the slice application. Further, it collects the slice parameter data corresponding to each AN-NSSMF within the connected regional scope, and determines the same target slice parameters and slice granularity for each AN-NSSMF within the regional scope under the implementation method of the slice application. Finally, according to the operation identifier of the slice application, the location information where the slice application is located, the target slice parameters, the slice granularity, and the slice parameter data, it generates the slice application operation instruction corresponding to the operation request of the slice application, and sends the slice application operation instruction to the AN-NSSMF corresponding to the location information where the slice application is located.

[0062] First, the nouns involved in this application are explained:

[0063] Network slice: A network slice is a way of networking on demand, which allows the operator to separate multiple virtual end-to-end networks on the unified infrastructure. Each network slice is logically isolated from the radio access network, the bearer network to the core network to adapt to various types of applications. In a network slice, it can be divided into at least three parts: the radio network sub-slice, the bearer network sub-slice, and the core network sub-slice.

[0064] Radio Access Network: A radio access network refers to a system where fixed users are connected to a switch partially or entirely in a wireless manner. A radio access network consists of a series of transmission entities between the service node (the switch) interface and the relevant user network interfaces, and is a wireless implementation system that provides the required transmission bearer capabilities for transmitting telecommunications services.

[0065] The network architecture for slice control of a radio access network involved in this application includes: a Communication Service Management Function network element (CSMF), a Slice Service Management Function network element (NMSF), an Access Network Network Subslice Management Function network element (AN-NSSMF), and an access network (AN).

[0066] Specifically, the Communication Service Management Function network element (CSMF) is connected to the Slice Service Management Function network element (NMSF); the Slice Service Management Function network element (NMSF) is connected to the Access Network Network Subslice Management Function network element (AN-NSSMF) within each regional scope; the Access Network Network Subslice Management Function network element (AN-NSSMF) is connected to all access networks (AN) pointed to by the Access Network Network Subslice Management Function network element (AN-NSSMF). Figure 1 It is a network architecture diagram for slice management of an existing radio access network. Among them, the total area in the network architecture can be, for example, the group side, and the sub-area in the network architecture can be, for example, the provincial company side.

[0067] Figure 2 It is a network architecture diagram for slice management of a radio access network provided by this application. Among them, the total area in the network architecture can be, for example, the group side, and the sub-area in the network architecture can be, for example, the provincial company side.

[0068] The 5G network slice service control method provided by this application can be applicable to Figure 2 the network architecture diagram for slice management of a radio access network as shown in Figure 2 As shown, this network architecture adds an Access Network Interface Unit - Network Slice Subnet Management Function (abbreviated as AN IU-NSSMF) on the basis of the existing network architecture for slice management of a radio access network.

[0069] Among them, the Access Network Interface Unit - Network Slice Subnet Management Function network element (AN IU-NSSMF) can be set between the Slice Service Management Function network element (NMSF) and the Access Network Network Subslice Management Function network element (AN-NSSMF).

[0070] Specifically, the slice service management function network element NMSF is connected to the access network centralized network sub-slice management function network element AN IU-NSSMF within each regional scope; the access network centralized network sub-slice management function network element AN IU-NSSMF is connected to multiple access network network sub-slice management function network elements AN-NSSMF within the regional scope;

[0071] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be elaborated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0072] Figure 3 It is a schematic flowchart of a 5G network slice service control method provided by the first embodiment of this application.

[0073] As Figure 3 shown, for the 5G network slice service control method of this embodiment, the execution entity is the access network centralized network sub-slice management function network element AN IU-NSSMF, which generally can be implemented through software, or hardware, or a combination of software and hardware. It may include the following steps:

[0074] Step S301, receive an operation request of a slice application sent by the slice service management function network element NMSF or input by a user from the interface of the access network centralized network sub-slice management function network element AN UI-NSSMF. The operation request of the slice application carries an operation identifier of the slice application and location information of the slice application;

[0075] Among them, NMSF is located in the Operation Support System (OSS for short). NMSF can receive the requirements of network slices sent by the CSMF in the Business Support System (BSS for short), that is, the operation request of the slice application, and send the requirements of the network slices to the access network centralized network sub-slice management function network element AN UI-NSSMF pointed to by each regional scope according to the regional scope.

[0076] In an implementation scenario, AN IU-NSSMF can receive the operation request of the slice application sent by the slice service management function network element NMSF to be used to undertake the management of the access network network sub-slice management function network element AN-NSSMF by the slice service management function network element NMSF in the existing network architecture. Among them, the operation request of the slice application carries an operation identifier of the slice application and location information of the slice application.

[0077] Among them, for users within the entire region, when users in some regional scopes have different requirements for the same slice application, that is, the operation requests for the slice application are different, users in the corresponding regional scopes can directly input the operation requests for the slice application from the AN UI-NSSMF interface. Among them, users can verify the operation requests for the slice application they input, that is, the parameters, and submit them after verification. Figure 4 This is an example diagram of the AN UI-NSSMF interface provided by the embodiment of the present application. Among them, the parameters filled in and selected in the interface may include: city, manufacturer, base station gNB ID, and slice implementation method. Among them, the implementation methods of slice applications based on the 5G service quality identifier 5QI include parameters such as 5QI values and uplink and downlink resource scheduling factors; the implementation methods of slice applications based on resource reservation RB include parameters such as slice SST, SD, uplink and downlink RB reservation ratios, as well as operators, core network types, and operation types.

[0078] In another implementation scenario, AN IU-NSSMF can receive the operation requests for slice applications input by users from the AN UI-NSSMF interface of the access network centralized network sub-slice management function network element, so as to implement the regionalized requirements and personalized settings of slice applications.

[0079] For example: For the fuel card business of a certain enterprise, its business service faces the gas stations of this enterprise across the country. When this enterprise puts forward the fuel card communication service requirement, that is, the communication service requirement, CSMF receives the communication service requirement of this enterprise and converts it into the requirement for network slices, that is, the operation request for the slice application, and sends it to NMSF. NMSF sends the operation request for the slice application to each regional scope according to the regional scope, such as: the access network centralized network sub-slice management function network element ANUI-NSSMF pointed to by each province. Among them, when some regional scopes of this enterprise, for example: some provinces, have different communication service requirements, for example: some provinces have higher requirements for network speed, the operation requests for the slice applications in some regional scopes can be directly input through the interface of the access network centralized network sub-slice management function network element AN UI-NSSMF in some regional scopes.

[0080] Among them, AN IU-NSSMF can provide an Application Program Interface (API for short) to achieve docking with the upper-level slice service management function network element NMSF.

[0081] Among them, in order to ensure that the network architecture is clear and easy to operate, the access network centralized network sub-slice management function network element ANIU-NSSMF can select, for example: a general PC Server as the application server for the operation of AN IU-NSSMF and the background database.

[0082] Step S302: Determine the implementation method of the slice application for the operation request of the slice application according to the operation request of the slice application.

[0083] Specifically, for different implementation methods of slice applications, the user service requirements implemented by the corresponding slice applications, that is, the functions of the slice applications, are different. Therefore, the user can propose requirements for network slices, that is, operation requests for slice applications, according to the functions of different slice applications. Therefore, the implementation method of the slice application for the operation request of the slice application can be determined according to the operation request of the slice application, so as to generate slice application operation instructions corresponding to different implementation methods of slice applications.

[0084] For example: The implementation method of the slice application for the operation request of the slice application can be confirmed according to the source of the operation request of the slice application described in step S301, or the implementation method of the slice application for the operation request of the slice application can be confirmed according to the operation identifier of the slice application carried in the operation request of the slice application.

[0085] Step S303: Collect the slice parameter data corresponding to each access network network slice management function network element AN-NSSMF within the connected area range.

[0086] Specifically, each AN IU-NSSMF can collect and store the slice parameter data corresponding to each access network network slice management function network element AN-NSSMF within the connected area range, that is, the configuration data and performance data of the existing slice application, at a certain time interval, for example, one day, for comparison with the slice application operation request received in the above step S301 to generate slice application operation instructions.

[0087] For example: For a certain enterprise in step S301, when the enterprise proposes a modification to the refueling card communication service requirement, this requirement can be converted into an operation request for the corresponding slice application. At this time, the corresponding slice parameter data can be collected from each AN-NSSMF within the area range connected by the AN IU-NSSMF for comparison with the above slice application operation request to generate a slice application operation instruction for modifying the parameters.

[0088] Among them, after the collection of the slice parameter data is completed, the collected slice parameter data can be preprocessed and saved in the database.

[0089] Step S304: Determine the same target slice parameters and slice granularity for each AN-NSSMF within the area range under the implementation method of the slice application, where the slice granularity represents the smallest network area implemented by the slice application.

[0090] Specifically, the understanding of the slice application by each manufacturer corresponding to the AN-NSSMF for each slice application implementation method may vary. Therefore, for an operation request for the same slice application, different AN-NSSMFs within the same region may implement different functions, further resulting in the user's inability to meet the actual requirements of the slice application.

[0091] Therefore, the same target slice parameters and slice granularity under the slice application implementation method can be determined for each AN-NSSMF within the region. The slice granularity represents the smallest network area where the slice application is implemented.

[0092] For example: For a slice application with an implementation method based on the 5G service quality identifier 5QI, the understanding of Manufacturer A is that the slice application is at the granularity of the 5G base station (the next Generation Node B, abbreviated as gNB), and the definition of the uplink and downlink scheduling factor parameters for the slice application does not distinguish between the slice general account ID, the cell, or the Public Land Mobile Network (abbreviated as PLMN); the understanding of Manufacturer B is that the slice application is at the granularity of the cell CELL, and the definition of the uplink and downlink scheduling factor parameters for the slice application only distinguishes between cells and does not distinguish between the slice ID and PLMN; the understanding of Manufacturer C is that the slice application is at the granularity of the cell CELL, and the definition of the uplink and downlink scheduling factor parameters for the slice application not only distinguishes between cells but also between the slice ID and PLMN. As described above, the business logic understood by Manufacturer C is the most complex, followed by Manufacturer B, and Manufacturer A is the simplest.

[0093] Therefore, starting from the actual functions implemented by the slice application and also to reduce the complexity of the development process, this embodiment proposes to determine the same target slice parameters and slice granularity under the slice application implementation method for each AN-NSSMF within the region, that is, to unify the business logic of the slice application corresponding to the implementation method of each slice application. The ANIU-NSSMF can form a unified business logic of the slice application corresponding to the implementation method of each slice application.

[0094] For example: For the implementation method of a slice application based on the 5G service quality identifier 5QI, each AN-NSSMF within the region determines the same slice granularity, that is, the slice application is at the granularity of the base station gNB, and determines the same target slice parameters: the 5QI value parameter and the uplink and downlink scheduling factor parameters, etc. That is, the definition of the uplink and downlink scheduling factor parameters for the slice application does not distinguish between the slice general account ID or the Public Land Mobile Network PLMN.

[0095] For example, for the implementation method of slice applications based on resource pre-reservation of RBs, each AN-NSSMF within the regional scope determines the same slice granularity, that is, the slice application uses the base station gNB as the granularity to determine the same target slice parameters: parameters such as slice / service type (SST for short), slice differentiator (SD for short), and uplink / downlink RB reservation ratio. That is, the definition of parameters for slice applications not only needs to distinguish between slice general account IDs and public land mobile networks (PLMNs), but also needs to distinguish between core networks.

[0096] Step S305: Generate a slice application operation instruction for the operation request of the corresponding slice application according to the operation identifier of the slice application, the location information where the slice application is located, the target slice parameters, the slice granularity, and the slice parameter data.

[0097] Specifically, as described in step S303, the AN IU-NSSMF collects the slice parameter data corresponding to each access network network sub-slice management function network element AN-NSSMF within the connected regional scope. According to the location information where the slice application is located, it can screen the slice parameter data corresponding to the location information where the slice application is located from the database described in step S303 above, and compare it with the operation identifier of the slice application corresponding to the location information where the slice application is located to generate a slice application operation instruction for the operation request of the corresponding slice application and with the same target slice parameters and slice granularity.

[0098] For example: When the location information carried in the operation request of the slice application is location A, the slice parameter data corresponding to location A can be found from the slice parameter data collected by the AN IU-NSSMF, and it is compared with the operation identifier carried in the operation request of the slice application to generate a slice application operation instruction.

[0099] Step S306: Send the slice application operation instruction to the AN-NSSMF corresponding to the location information where the slice application is located.

[0100] Specifically, the slice application operation instruction for the operation request of the corresponding slice application generated in step S305 can be sent to the access network network sub-slice management function network element AN-NSSMF corresponding to the location information where the slice application is located for implementing the corresponding slice application operation. Among them, in the face of different manufacturers corresponding to AN-NSSMFs, the docking methods between the AN IU-NSSMF and the access network network sub-slice management function network element AN-NSSMF are different. Table 1 is an example of the docking methods of different manufacturers.

[0101] Table 1

[0102] Manufacturer AN-NSSM Address Protocol Username Password Port Number Manufacturer A IP1 Telnet / / Port1 Manufacturer B IP2 Open API / / Port2 Manufacturer C IP3 SSH / / Port3

[0103] Among them, the AN-NSSM addresses, protocols, and port numbers corresponding to different manufacturers are all different. For example, the AN-NSSM address of manufacturer A is IP1, the communication protocol is the Telnet protocol, and the port number is Port1

[0104] The 5G network slice service control method provided in this embodiment receives an operation request of a slice application sent by a slice service management function network element NMSF or input by a user from an access network centralized network sub-slice management function network element AN UI-NSSMF interface, and determines an implementation manner of the slice application for the operation request of the slice application according to the operation request of the slice application. Among them, the user can input an operation request of a slice application through the AN UI-NSSMF interface of the access network centralized network sub-slice management function network element, which realizes the personalized requirements of the slice function. Further, slice parameter data corresponding to each access network network sub-slice management function network element AN-NSSMF within the connected area range is collected, and the same target slice parameters and slice granularity under the implementation manner of the slice application are determined for each AN-NSSMF within the area range. Among them, determining the same target slice parameters and slice granularity reduces the complexity of the implementation of the slice application function. Finally, according to the operation identifier of the slice application, the location information where the slice application is located, the target slice parameters, the slice granularity, and the slice parameter data, a slice application operation instruction corresponding to the operation request of the slice application is generated, and the slice application operation instruction is sent to the AN-NSSMF corresponding to the location information where the slice application is located. The above method makes the control of the 5G network slice service more accurate.

[0105] Figure 5 It is a schematic flow chart for determining an implementation manner of a slice application for an operation request of a slice application provided in the second embodiment of this application. In Figure 4 Based on the shown embodiment, this embodiment expands and describes the process of determining an implementation manner of a slice application for an operation request of a slice application. Among them, the implementation manner of the slice application includes: an implementation manner of the slice application based on the 5G service quality identifier 5QI and an implementation manner of the slice application based on resource reservation RB.

[0106] As Figure 5 shown, the method for determining an implementation manner of a slice application for an operation request of a slice application in this embodiment may include the following steps:

[0107] Step S501, if the operation request of the slice application is an operation request of the slice application sent by the NMSF, determine that the implementation manner of the slice application is an implementation manner of the slice application based on resource reservation RB.

[0108] Specifically, when the operation request for the slice application received by the AN IU-NSSMF comes from the NMSF, there is only one implementation method for the slice application, that is, the implementation method of the slice application based on resource reservation RB.

[0109] Step S502: If the operation request for the slice application is the operation request for the slice application input by the user from the AN UI-NSSMF interface, determine the implementation method of the slice application for the operation request of the slice application according to the identifier of the operation request of the slice application.

[0110] Specifically, when the operation request for the slice application received by the AN IU-NSSMF comes from the AN UI-NSSMF interface, the implementation methods of the slice application can include two types, that is, the implementation method of the slice application based on resource reservation RB and the implementation method of the slice application based on the 5G service quality identifier 5QI. At this time, the implementation method of the slice application for the operation request of the slice application can be determined according to the identifier of the operation request carried by the operation request of the slice application.

[0111] Among them, the identifier of the operation request of the slice application is used to indicate the type of the slice implementation method.

[0112] If the type of the slice implementation method is the implementation method based on resource reservation RB, determine that the implementation method of the slice application is the implementation method of the slice application based on resource reservation RB.

[0113] If the type of the slice implementation method is the implementation method based on the 5G service quality identifier 5QI, determine that the implementation method of the slice application is the implementation method of the slice application based on the 5G service quality identifier 5QI.

[0114] In the process of determining the implementation method of the slice application for the operation request of the slice application provided in this embodiment, the operation request of the slice application is first divided into two types of operation requests for the slice application sent by the NMSF or input by the user from the AN UI-NSSMF interface according to different sources, and then the implementation methods of the slice application for the operation requests of different sources are determined respectively. Among them, when the operation request for the slice application is the operation request for the slice application input by the user from the AN UI-NSSMF interface, the implementation methods of the slice application for the operation request of the slice application can include two types. On the basis of the existing implementation methods of the slice application, the implementation method of the slice application based on the 5G service quality identifier 5QI is added, making the control of the 5G network slice service more accurate.

[0115] Figure 6Schematic diagram of a slice application operation instruction for generating an operation request for a corresponding slice application according to an operation identifier of a slice application, location information where the slice application is located, target slice parameters, slice granularity, and slice parameter data provided in the third embodiment of this application. In Figure 4 Based on the embodiment shown, this embodiment expands the description of the process of generating a slice application operation instruction for an operation request for a corresponding slice application according to an operation identifier of a slice application, location information where the slice application is located, target slice parameters, slice granularity, and slice parameter data. Among them, the operation types of the operation requests for slice applications include: modify slice requests and add slice requests.

[0116] As Figure 6 shown, the slice application operation instruction for generating an operation request for a corresponding slice application according to an operation identifier of a slice application, location information where the slice application is located, target slice parameters, slice granularity, and slice parameter data in this embodiment may include the following steps:

[0117] Step S601, when the slice application operation request is a modify slice request, determine whether there is a slice to be modified pointed to by the modify slice request according to the operation identifier of the slice application, the location information where the slice application is located, and the slice parameter data.

[0118] Specifically, after determining the implementation method of the slice application for the operation request of the slice application through steps S501 - S502, the operation type of the operation request of the slice application can be further determined. Among them, when the implementation method of the slice application is the implementation method of the slice application based on the 5G service quality identifier 5QI, the operation type of the operation request of the slice application can be a modify slice request; when the implementation method of the slice application is the implementation method of the slice application based on resource reservation RB, the operation types of the operation request of the slice application can be a modify slice request and an add slice request;

[0119] Specifically, when the slice application operation request is a modify slice request, the slice parameter data corresponding to the location information where the slice application is located carried in the slice application operation request can be screened from the database described in step S303, and compared with the operation identifier carried in the slice application operation request to determine whether there is a slice to be modified pointed to by the modify slice request.

[0120] Step S602, if there is a slice to be modified, generate a slice application operation instruction for modifying the resource reservation RB slice parameters and / or a slice application operation instruction for modifying the 5G service quality identifier 5QI slice parameters according to the target slice parameters and the slice granularity.

[0121] Specifically, after the judgment in step S601, if there are slices to be modified, slice application operation instructions for modifying slice parameters can be generated according to the target slice parameters and slice granularity. Among them, when the implementation method of slice application is the implementation method of slice application based on resource reservation RB, the generated slice application operation instruction is a slice application operation instruction for modifying the slice parameters of resource reservation RB; when the implementation method of slice application is the implementation method of slice application based on 5G service quality identifier 5QI, the generated slice application operation instruction is a slice application operation instruction for modifying the slice parameters of 5G service quality identifier 5QI.

[0122] Specifically, after the judgment in step S601, if there are no slices to be modified, the situation that there are no slices to be modified in the existing slice application is fed back to the AN UI-NSSMF interface corresponding to the slice application operation instruction or the CSMF connected to the NMSF.

[0123] Step S603, when the slice application operation request is an add slice request, determine whether there is a slice identical to the slice to be added pointed to by the add slice request according to the location information where the slice application is located and the slice parameter data.

[0124] Specifically, as described in step S601, when the implementation method of slice application is the implementation method of slice application based on resource reservation RB, the operation type of the slice application operation request can be a modify slice request and an add slice request. Therefore, when the slice application operation request is an add slice request, the slice parameter data corresponding to the location information where the slice application is located carried by the above slice application operation request can be filtered from the database described in step S303, and compared with the operation identifier carried by the above slice application operation request to determine whether there is a slice identical to the slice to be added pointed to by the add slice request.

[0125] Step S604, if there is no slice identical to the slice to be added, generate a slice application operation instruction for adding slice parameters of resource reservation RB according to the target slice parameters and slice granularity.

[0126] Specifically, after the judgment in step S603, if there is no slice identical to the slice to be added, a slice application operation instruction for adding slice parameters can be generated according to the target slice parameters and slice granularity. As described in step S601, only when the implementation method of slice application is the implementation method of slice application based on resource reservation RB, the operation type of the slice application operation request can be an add slice request. Therefore, the above slice application operation instruction for adding slice parameters is a slice application operation instruction for adding slice parameters of resource reservation RB.

[0127] Specifically, after the judgment in step S601, if there is a slice identical to the slice to be added, the situation where there is a slice identical to the slice to be added in the existing slice application is fed back to the AN UI-NSSMF interface corresponding to the slice application operation instruction or the CSMF connected to the NMSF.

[0128] The process of generating an operation request for a corresponding slice application operation instruction according to the operation identifier of the slice application, the location information where the slice application is located, the target slice parameters, the slice granularity, and the slice parameter data provided in this embodiment adds the process of generating an operation instruction for a slice application that modifies the 5G service quality identifier 5QI slice parameters, making the control of 5G network slice services more precise.

[0129] Figure 7 It is a schematic flowchart of receiving and feeding back the operation result of the slice application provided in the fourth embodiment of this application. Figure 4 On the basis of the shown embodiment, the AN UI-NSSMF will also feed back the operation result of the slice application to the source corresponding to the operation request of the slice application. This embodiment expands the description of receiving and feeding back the operation result of the slice application.

[0130] As Figure 7 shown, the process of receiving and feeding back the operation result of the slice application in this embodiment may include the following steps:

[0131] Step S701, receive the operation result of the slice application fed back by the AN-NSSMF.

[0132] Specifically, in step S306, after sending the slice application operation instruction to the AN-NSSMF corresponding to the location information where the slice application is located, the AN-NSSMF performs slice operation on the access network AN corresponding to the location information where the slice application is located according to the slice application operation instruction.

[0133] Specifically, the AN-NSSMF may send the result of the above slice operation, that is, the operation result of the slice application, to the ANUI-NSSMF.

[0134] Step S702, feed back the operation result of the slice application to the NMSF or / and the AN UI-NSSMF interface.

[0135] Specifically, the AN UI-NSSMF may send the operation result of the slice application received in step S701 above to the NMSF or / and the AN UI-NSSMF interface corresponding to the operation request of the slice application, where the NMSF feeds back the operation result of the slice application to the CSMF connected to the NMSF.

[0136] The process of receiving and feeding back the operation result of the slice application provided in this embodiment feeds back the operation result of the slice application to the user, enabling the user to have a more intuitive understanding of the result of the slice operation.

The slice granularity represents the smallest network area for the implementation of the slice application, and generate a slice application operation instruction corresponding to the operation request of the slice application according to the operation identifier of the slice application, the location information of the slice application, the target slice parameters, the slice granularity, and the slice parameter data.

[0143] The sending module 85 is configured to send the slice application operation instruction to the AN-NSSMF corresponding to the location information of the slice application.
