Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the present invention relates to a Slice management method, which is applied to a Network Slice sales platform (NS Store for short). The slice in this embodiment and the following embodiments may be a network slice, and a network slice may be understood as a network slice that is customized according to different service requirements on a physical or virtual network infrastructure. The NS Store may be an operation Management platform connecting a user and an operator, the NSStore may provide functions such as slicing product classification, slicing product display, slicing product recommendation, order Management, and user Management, and may also provide an interface for adding, deleting, and modifying a slicing product for a slicing Management System (NSMS) inside the operator, and provide a purchase flow of the slicing product for the user and the operator, where adding, deleting, and modifying may be understood as adding, deleting, modifying, and querying the slicing product for the NSMS on the NS Store. The NSMS may be responsible for functions of design, online, instantiation, modification, termination, and the like of a sliced product, and interface with a network function virtualization management orchestrator (NFV MANO for short) of an operator to realize management of network slices. The following describes implementation details of the slice management method according to the present embodiment in detail, and the following is only provided for easy understanding and is not necessary for implementing the present embodiment.
As shown in fig. 1, the slice management method in the present embodiment may specifically include:
step 101: and recommending the slicing products to the user after receiving the query request information of the user.
Specifically, the user can send query request information to the NS Store through the terminal device, and after receiving the query request information sent by the user through the terminal device, the NS Store can push the slicing product on-line on the NS Store to the terminal used by the user, so that the user can view the slicing product recommended by the NS Store through the terminal. The user can select among the slicing products recommended by NSStore to select the required slicing product.
In one example, the slicing products on the NS Store may be pre-labeled with scene labels, and slicing products applicable to different application scenes are labeled with different scene labels, and the different application scenes may include: an enhanced mobile broadband (eMB) scene, which has high requirements for bandwidth and rate and needs xGbps bandwidth, such as virtual reality, augmented reality, and other scenes; a massive machine type communication (mtc) scenario, where the mtc scenario needs to support massive device access, for example, hundreds of millions or billions of devices need to be supported, for example, a wearable scenario, a smart grid, and other scenarios; ultra-reliable low-latency communications (urrllc) scenarios need to support ultra-low latency of 1ms, such as scenarios of automatic driving, remote surgery, industrial control, and the like. The application scenarios in the present embodiment are only the above-described eMBB scenario, mtc scenario, and urrllc scenario, and are not limited to this in practical applications. The NS Store may classify the sliced products on the platform according to the applicable application scenarios, and label the sliced products with corresponding scenario labels. For example, an eMBB tag is added to a slice product applicable to an eMBB scene, and an mtc tag is added to a slice applicable to an mtc scene. It can be understood that mtc tags can be added to virtual reality slicing products and augmented reality slicing products, and urrllc tags can be added to industrial control slicing products, medical control slicing products, automatic driving control slicing products, and the like.
In one example, after receiving the query request information of the user, the NS Store may first show the slicing products labeled with different scene tags, which are applicable to different application scenes, to the user, and specifically, the NS Store may optionally select the slicing products labeled with different scene tags to show to the user, and the user may select one of the scene tags according to the scene tags labeled with the respective slicing products. The mode of the user selecting the scene tags may also be that the NS Store directly displays all the scene tags to the user, and the user selects one of the scene tags displayed on the NS Store. The NS Store recommends the slicing product labeled with the user-selected scene tag to the user according to the user-selected scene tag. For example, if the scene tag selected by the user according to the actual requirement is a uRLLC tag, the NS Store may recommend to the user the industrial control slicing product, the medical control slicing product, the automatic driving control slicing product, and other slicing products labeled with the uRLLC tag.
In one example, the NS Store may directly carry the scene tag in the query request information received from the user, and recommend the slicing product labeled with the carried scene tag to the user according to the scene tag carried in the query request information. For example, if the scene tag carried in the query request information received by the NS Store is an mtc tag, the NS Store may recommend slice products such as virtual reality slice products and augmented reality slice products labeled with the mtc tag to the user.
Step 102: an order is generated according to the sliced product selected by the user.
Specifically, the NS Store may provide the user with a slicing template corresponding to the selected slicing product according to the slicing product selected by the user, so that the user fills in parameters of performance indexes of the slicing template. The slicing products suitable for different application scenes correspond to different slicing templates, that is, different application scenes correspond to different slicing templates, and the slicing templates can be used for refining parameters of performance indexes of the slicing products. The performance index may include: rate, delay, access amount, etc. The slice templates corresponding to different application scenes have respective outstanding performance, and the following description takes the slice template corresponding to the eMBB scene as an example: it can be appreciated that the eMBB scenario has high requirements on the rate and relatively low requirements on the access amount and the delay.
In an example, a slice template corresponding to the eMBB scenario may provide a plurality of parameter values for a rate to be selected by a user, for example, 10 parameter values may be provided, and a smaller parameter value may be provided for the user to be selected for an access amount and a delay, for example, the parameter value may be fixed to be within 3, so as to highlight a key characteristic, that is, the rate, in the eMBB scenario. And finally, the parameter value of each performance index selected by the user is the parameter of the performance index of the slice template filled by the user.
In another example, a plurality of parameter value ranges may be provided for the user to refer to for the rate in the slicing template corresponding to the eMBB scene, and the user may refer to the parameter value ranges of the rate in the slicing template and select one parameter value in one of the parameter value ranges as a parameter value of the rate of the filled slicing template according to actual requirements. For the access amount and the time delay, the slice template corresponding to the eMB scene may also provide a plurality of parameter value ranges for the user to refer to, but the number of the parameter value ranges provided for the access amount and the time delay in the eMB scene is smaller than the number of the parameter value ranges provided for the rate, so as to highlight the key characteristics in the eMB scene. For example, the number of parameter value ranges provided for the access amount and the delay is fixed within 3, and the number of parameter value ranges provided for the rate is fixed to 10. It should be noted that, in the present embodiment, the number of parameter values or parameter value ranges provided for different performance indexes is only an example of the number, and is not limited in practical application.
It can be understood that, in the embodiment, different application scenarios correspond to different slice templates, and in the same application scenario, parameter values filled by a user according to requirements may also have differences for the same slice template, so that the network resources with different dimensional parameter performances provided for the same application scenario are facilitated to meet actual requirements of different users.
In this embodiment, after acquiring the parameters of the performance indexes of the slice template filled by the user, the NS Store may generate the order information according to the parameters of the performance indexes of the slice template filled by the user. The order information may include user information, parameters of performance indexes filled by the user, amount of money to be paid by the user, and the like, and the user information may be a company or an individual user name, account information, a physical address, and the like. The NS Store may feed back the generated order information to the user, who may choose whether to complete payment for the order after viewing the order information.
Step 103: and after the successful payment to the order is detected, the information of the order is sent to the network slicing management system, so that the network slicing management system can create a network slicing instance according to the information of the order.
Specifically, after detecting that the order is successfully paid, the NS Store may send the information of the order to the NSMS, so that the NSMS may further obtain, according to the received order information, the user information and the parameter of the performance index of the slice template filled by the user, and the NSMS may create the network slice instance according to the user information and the parameter of the performance index of the slice template filled by the user.
In this embodiment, the method for creating the network slice instance by the NSMS may be as follows: the NSMS generates a Network Service Descriptor (NSD) file according to the received order information. Specifically, the NSMS may generate an NSD file according to a parameter of a performance index in the information of the order, where the NSD file is used to describe a network topology of the network slice instance that needs to be created and required resource information. Then, the NSMS sends the generated NSD file to the NFVMANO of the operator, the NFV MANO parses the NSD file to generate a Virtualization Network Function Descriptor (VNFD) file, the VNFD file describes a configuration template of deployment and operation behaviors of each Virtualization Network Function (VNF), a Network Slice Instance can be created by using the VNFD file, and lifecycle management of the Network Slice Instance (NSI) is implemented. The instance of the network slice created by the NFV MANO is a logical network that operates in reality and can satisfy the network services required by the user.
For facilitating understanding of the present embodiment, reference may be made to a networking structure diagram of the slice providing method shown in fig. 2, which includes a user side 201, an NS Store202, an NSMS203, an NFV MANO204, an Element Management System (EMS) 205, a VNF206, and a Network Function Virtualization Infrastructure (NFVI) 207. The EMS205 is configured to issue service configuration of the network function to the network function. VNF206 may be deployed in an implementation of a network function module of a network function virtualization infrastructure. NFVI207 is a generic term for all hardware devices and software components in an environment with the capability to deploy network function virtualization. The implementation process of the method for providing slices in the networking structure may be as follows: the method comprises the steps that a user side 201 sends query request information to an NSStore202, the NS Store202 recommends slicing products to the user side 201, the user side 201 feeds back slicing products selected by a user to the NSStore202, the NS Store202 generates an order according to the slicing products selected by the user, after successful payment of the order is detected, the information of the order is sent to an NSMS203, the NSMS203 generates an NSD file according to the information of the order and sends the NSD file to an NFV MANO204, the NFV MANO204 analyzes the NSD file to obtain a VNFD file, and during the process of creating a network slicing example, virtualized network function deployment and operation information captured in the VNFD file, and additional operation example specific information and constraint conditions are used.
Specifically, the NFV MANO204 is responsible for managing and orchestrating the entire network function virtualization infrastructure and NFVI resources, for mapping and associating the service network and NFVI resources, for implementing the Operation Support System (OSS) service resource flow, and the like. The NFV MANO204 includes a Network Function Virtualization Orchestrator (NFVO) 2041, a Virtualized Network Function module Manager (VNFM) 2042, and a Virtualized Infrastructure Manager (VIM) 2043. The NFVO2041 is configured to manage a Network Service (NS) lifecycle, coordinate management of the NS lifecycle, coordinate management of the VNF lifecycle (which needs to be supported by a VNF manager VNFM), and coordinate management of various NFVI resources (which needs to be supported by a VIM), so as to ensure optimal configuration of various required resources and connections. VNFM2042 is used for lifecycle management of virtualized network function modules. The VIM2043 is responsible for controlling and managing the NFVI computing, storage, and network resources.

And then the network slicing sale platform generates an order according to the slicing product selected by the user, and after the successful payment to the order is detected, the information of the order is sent to the network slicing management system, so that the network slicing management system creates a network slicing example according to the information of the order, and a process based on the online direct purchasing and payment of the user is provided, so that the network slicing management system can create the network slicing example according to the information of the order, and the created network slicing example can provide network service required by the user. The embodiment of the invention introduces a network slicing sale platform and a network slicing management system of an operator between a user and the operator, provides an online and operation flow of slicing products facing the operator, and also provides an online recommendation, purchase and payment flow facing the user, thereby providing convenience for communication between the user and the operator, reducing the communication cost between the user and the operator, reducing the time spent for ordering proper slicing products, and facilitating the user to select required slicing products, thereby obtaining required network services.
A second embodiment of the present invention relates to a slice management method. In this embodiment, an implementation manner for modifying an already created network slice instance is provided, so as to conveniently meet the change of the actual needs of the user.
As shown in fig. 5, the slice management method in the present embodiment may specifically include:
step 501: and recommending the slicing products to the user after receiving the query request information of the user.
Step 502: an order is generated according to the sliced product selected by the user.
Step 503: and after the successful payment to the order is detected, the information of the order is sent to the network slicing management system, so that the network slicing management system can create a network slicing instance according to the information of the order.
Steps 501 to 503 are substantially the same as steps 101 to 103 in the first embodiment, and are not repeated here.
Step 504: and if receiving modification request information of the parameters of the performance indexes of the slicing template from the user, providing the slicing template for the user.
Specifically, along with the change of the actual requirement of the user, if the network service provided by the created network slice example gradually fails to meet the requirement of the user, the user may send modification request information to the NS Store through the terminal, after receiving the modification request information sent by the user, the NSStore may search the slice template filled by the user according to the information of the user, provide the slice template filled by the user to the user, and the user may modify one or more parameter values of the performance index once filled in the slice template provided by the NS Store according to the actual requirement.
Step 505: and acquiring parameters of the performance indexes of the slice template modified by the user.
For example, the parameter value of the performance index of the slice template modified by the user may be sent to the NS Store through the terminal used by the user, so that the NS Store obtains the parameter of the performance index of the slice template modified by the user.
Step 506: and generating a modified order according to the parameters of the performance indexes of the modified slice template.
Specifically, the modified order is substantially the same as the order before modification, except that the parameters of the performance index of the slice template are changed, and the information of the modified order may include: parameters of performance indexes of the modified slice template, user information and the amount of money the user needs to pay for the modified order. In one example, the more parameters of the performance indicators that are modified, the more amount that needs to be paid for the modification, e.g., modifying the parameter values of two performance indicators may require a larger amount to be paid than modifying the parameter values of one performance indicator. The NS Store may feed back information of the modified order to the user, and the user may confirm the parameters of the modified performance index again and determine whether to complete the payment according to the amount of money to be paid, which is fed back by the NS Store.
Step 507: and after the payment success of the modified order is detected, sending the information of the modified order to a network slice management system.
Specifically, the NS Store may send information of the modified order to the NSMS upon detecting that the payment of the modified order by the user is successful. The NSMS may obtain the user information and the parameter of the performance index of the modified slice template according to the received modified order information, then search for the network slice instance created for the user, and modify the network slice instance created for the user according to the parameter of the performance index of the modified slice template.
In this embodiment, the method for the NSMS to modify the network slice instance according to the modified order information may be as follows: the NSMS determines whether the network service descriptor NSD file needs to be changed according to the modified information of the order. And if the NSMS determines that the NSD file needs to be changed, the NSD file is changed, and the changed NSD file is sent to the NFV MANO so that the NFVMANO can modify the network slice example according to the changed NSD file. The NSD file to be changed may be a new VNF that needs to be added for the modification operation, and changing the NSD file may be a new NSD file that is regenerated according to the modified parameter of the performance index of the slice template. And if the NSMS determines that the NSD file does not need to be changed, sending a capacity expansion and reduction request to the NFVMANO according to the modified order information so that the NFV MANO can modify the network slice example according to the capacity expansion and reduction request. If the NSMS determines that the NSD file does not need to be changed, the modification operation can be realized through the capacity expansion VNF, and then a capacity expansion and reduction request is issued to the NFV MANO.
In a specific implementation, the NSMS may send an abort request of an original network service while sending the changed NSD file to the NFV MANO, where the original network service refers to a network service provided by a network slice instance before modification, so that the modified network slice instance provides a new network service for a user to meet an actual requirement of the user.
For the convenience of understanding the embodiment, the following description takes an interaction diagram of a user requesting to modify a sliced product as an example, and refers to fig. 6:
step 601: the User sends a modification request message to the NS Store.
Step 602: NS Store provides a modification template to User; the modification template is a slice template which is searched according to the user information and is filled by the user.
Step 603: the User feeds back a modification parameter to the NS Store; the feedback modification parameters are parameters of performance indexes of the slice template modified by the user according to actual needs.
Step 604: the NS Store generates a modified order; the modified order can be generated according to the modification parameters fed back to the NS Store by the User.
Step 605: the NS Store sends the modified order information to the User; the modified order information includes modified parameter values, user information, and the amount of money to be paid by the user for modification operation.
Step 606: the User completes payment; here, the payment completion means that the user completes payment for the modified order.
Step 607: the NS Store sends the modified order information to the NSMS.
Step 608: the NSMS determines whether the NSD file needs to be changed; if so, step 609 is performed, otherwise step 612 is performed.
Step 609: the NSD file is altered.
Step 610: the NSMS sends the modified NSD file to the NFV MANO.
Step 611: the NFV MANO combines with the EMS/VNF to modify the network slice example according to the changed NSD file; step 611 may be executed and then step 614 may be directly executed.
Step 612: the NSMS sends a scale-out request to the NFV MANO.
Step 613: the NFV MANO combines with the EMS/VNF to modify the network slice example according to the expansion and contraction capacity request; step 614 may be directly entered after step 613 is executed.
Step 614: the NFV MANO feeds back instantiation or expansion and contraction capacity completion to the NSMS; wherein, if step 611 directly enters step 614, the NFV MANO feeds back the completion of instantiation to NSMS, and if step 613 directly enters step 614, the NFV MANO feeds back the completion of scaling to NSMS.
Step 615: the NSMS feeds back to the NS Store that the modification is complete.
Step 616: the NS Store feeds back to the user that the modification is complete.
