Detailed Description

The technical scheme of the invention is further elaborated by combining the drawings and the embodiments in the specification.

In the related art, after a user puts forward requirements such as a service type, a service range, a performance index requirement, a special function characteristic and the like, research and development personnel can realize the overall design of an end-to-end network slice based on the following two ways:

the first method is a blueprint design method.

Specifically, a Network Slice Management Function (NSMF) entity may obtain a Network Slice blueprint according to a user requirement, where the Network Slice blueprint is a module example of a Network Slice and is used to describe a structure, configuration, workflow, and the like of the Network Slice; the NSMF can complete automatic instantiation of the network slices and control management of the life cycles of the network slices according to the definition of the acquired network slice blueprints.

And the second mode is a parameter configuration method.

Specifically, a plurality of application scenarios can be determined according to the requirements of the user, and the service type and configuration parameters of the corresponding network slice are determined according to each determined application scenario; the configuration parameters characterize network resources, computing resources and storage resources of the corresponding network slice; and generating a corresponding network slice example according to the service type and the configuration parameters of the corresponding network slice to obtain a network slice example corresponding to each application scene in the plurality of application scenes.

However, when the instantiation of the end-to-end network slice is realized by adopting the two methods, the following defects exist:

first, when the network slice is automatically instantiated based on the first method, since uniform parameter configuration is not performed on each sub-network slice included in the network slice, information interaction between the sub-network slices may not be performed.

Secondly, when the automatic instantiation of the network slice is realized based on the second mode, for a plurality of application scenes, if the application scenes are different, the service types of the network slice corresponding to the corresponding application scenes are also different, that is, the parameters to be configured for the network slice corresponding to the corresponding application scene are different; therefore, the network slice corresponding to each application scene needs to be configured with parameters, which results in large workload, low efficiency of generating network slice instances, and poor user experience.

Based on this, in various embodiments of the present invention, according to a user's requirement, a plurality of sub-network slice templates and an end-to-end network slice template are determined, a configuration parameter corresponding to each sub-network slice template is determined, a corresponding sub-network slice instance is generated by using each sub-network slice template and a corresponding configuration parameter, and a corresponding end-to-end network slice instance is generated by using the end-to-end network slice template and the generated plurality of sub-network slice instances.

An embodiment of the present invention provides a method for processing a network slice, as shown in fig. 1, the method includes the following steps:

step 101: acquiring first information; the first information represents the service requirement of a user on the end-to-end network slice;

step 102: determining a plurality of sub-network slice templates and an end-to-end network slice template consisting of the plurality of sub-network slice templates according to the first information, and determining configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates;

here, each sub-network slice template of the plurality of sub-network slice templates corresponds to a sub-network domain of an end-to-end network slice; the configuration parameters comprise a first type of parameters and a second type of parameters; the first type of parameters are used for supporting information interaction between sub-network domains of the end-to-end network slice; the second type of parameters are used for supporting the network service of the sub-network domain corresponding to the corresponding sub-network slice template;

step 103: determining a sub-network slice example corresponding to each sub-network slice template by using the configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates to obtain a plurality of sub-network slice examples;

step 104: determining an end-to-end network slice instance using the end-to-end network slice template and the obtained plurality of sub-network slice instances.

It should be noted that the method for processing a network slice provided in the embodiment of the present invention is applied to a management system of a network slice, where the management system at least includes the following functional entities: a Communication Service Management Function (CSMF), an NSMF, and a sub-Slice Management Function (NSSMF).

In step 101, in actual application, the acquiring of the first information may include:

receiving user demand information;

and determining first information according to the received user demand information.

Specifically, a user can order an end-to-end network slice through CSMF, and submit the self requirement information of the end-to-end network slice at the CSMF, namely the CSMF receives the user requirement information; the user requirement information can comprise the requirements of online user quantity, network bandwidth, time delay and the like; after receiving the user requirement information, the CSMF analyzes a Service Level Agreement (SLA) on the user requirement information to determine the first information; the meaning of SLA analysis of the user requirement information by the CSMF is as follows: CSMF translates the user demand information into SLA defining the communication service type of the end-to-end network slice the user subscribes to. Here, the SLA converted from the user requirement information is the first information; the first information may include parameters such as a type of the network slice, a capability requirement of the network slice, a maximum number of user concurrencies of the network slice, a service area of the network slice, a delay of the network slice, and an isolation requirement of the network slice.

In step 102, in actual application, after obtaining the first information, the CSMF may send the first information to the NSMF, and the NSMF determines, according to the first information, a plurality of sub-network slice templates and an end-to-end network slice template composed of the plurality of sub-network slice templates. Moreover, a network slice template library may be preset in the NSMF, and after receiving the first information sent by the CSMF, the NSMF may select a plurality of sub-network slice templates and an end-to-end network slice template that match the first information from the network slice template library; therefore, the efficiency of generating the end-to-end network slice example can be improved, and the user experience is further improved.

Based on this, in an embodiment, the determining a plurality of sub-network slice templates and an end-to-end network slice template composed of the plurality of sub-network slice templates may include:

selecting a plurality of sub-network slice templates and end-to-end network slice templates in a network slice template library that match the first information.

In practical application, a plurality of sub-network slice templates and/or end-to-end network slice templates which are matched with the first information may not exist in the network slice template library; at this time, a plurality of sub-network slice templates and/or end-to-end network slice templates corresponding to the first information may be created, and the created plurality of sub-network slice templates and/or end-to-end network slice templates may be stored in the network slice template library.

Based on this, in an embodiment, the determining a plurality of sub-network slice templates and an end-to-end network slice template composed of the plurality of sub-network slice templates may further include:

In practical application, in the process of selecting a plurality of sub-network slice templates and end-to-end network slice templates matching with the first information in the network slice template library by the NSMF, the following three situations may exist.

The first condition is as follows: an end-to-end network slice template matching the first information exists in a network slice template library, but a plurality of sub-network slice templates matching the first information does not exist. At this time, an end-to-end network slice template matching the first information may be acquired from a network slice template library, and a plurality of sub-network slice templates matching the first information may be created according to the acquired end-to-end network slice template.

Case two: a plurality of sub-network slice templates exist in the network slice template library that match the first information, but an end-to-end network slice template that matches the first information does not exist. At this time, a plurality of sub-network slice templates matching the first information may be acquired from a network slice template library, and an end-to-end network slice template matching the first information may be created based on the acquired plurality of sub-network slice templates. Here, when the plurality of sub-network slice templates matching the first information are obtained from the network slice template library, the requirement information corresponding to each of the plurality of sub-network domains of the end-to-end network slice may be determined according to the first information, and then the corresponding sub-network slice template matching the corresponding requirement information may be obtained from the network slice template library according to the requirement information corresponding to each sub-network domain. In practical application, the first information may be an SLA, and the determining, according to the first information, the requirement information corresponding to each sub-network domain in the multiple sub-network domains of the end-to-end network slice may be decomposing the SLA; that is, the SLA is decomposed into SLAs for each of a plurality of sub-network domains of the end-to-end network slice.

Case three: a plurality of sub-network slice templates and end-to-end network slice templates that match the first information are not present in the network slice template library. At this time, the requirement information corresponding to each sub-network domain in the plurality of sub-network domains of the end-to-end network slice may be determined according to the first information, and a sub-network slice template corresponding to a corresponding sub-network domain is created by using the requirement information corresponding to each sub-network domain, so as to obtain a plurality of sub-network slice templates matched with the first information; and then, a plurality of sub-network slice templates are utilized to create an end-to-end network slice template matched with the first information.

Based on this, in an embodiment, creating a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information may include:

In practical application, in the process of creating a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information, if the NSMF and the NSSMF are on the same functional node, the NSMF and the NSSMF can share information; at this time, a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information may be created in a direct mode.

Specifically, creating a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information in a direct mode may include: NSMF decomposes SLA (i.e. the first information); that is, the SLA is decomposed into SLAs corresponding to each sub-network domain in a plurality of sub-network domains of an end-to-end network slice (i.e. the requirement information corresponding to each sub-network domain), and the SLAs of sub-network domains such as a core network, a wireless network, a transport network, an IP network, etc. are obtained; respectively creating sub-network slice templates corresponding to the sub-network domains such as the core network, the wireless network, the transmission network, the IP network and the like according to SLAs of the sub-network domains such as the core network, the wireless network, the transmission network, the IP network and the like; and finally, creating an end-to-end network slicing template according to the created sub-network slicing templates corresponding to the sub-network domains such as the core network, the wireless network, the transmission network, the IP network and the like.

In practical application, in the process of creating a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information, if the NSMF and the NSSMF are hierarchically arranged, that is, not on the same functional node, the NSMF and the NSSMF cannot share information; at this time, a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information may be created in an indirect mode.

Specifically, the creating, by using an indirect mode, a plurality of sub-network slice templates and end-to-end network slice templates corresponding to the first information may include: NSMF decomposes SLA (i.e. the first information); that is to say, the SLA is decomposed into SLAs corresponding to each sub-network domain in a plurality of sub-network domains of the end-to-end network slice (that is, requirement information corresponding to each sub-network domain), the SLAs of the sub-network domains such as the core network, the wireless network, the transport network, and the IP network are obtained, and the obtained SLAs of the sub-network domains such as the core network, the wireless network, the transport network, and the IP network are respectively sent to NSSMFs of the sub-network domains such as the core network, the wireless network, the transport network, and the IP network (here, a sub-network slice template request message including the SLAs of the corresponding sub-network domain may be sent to the NSSMFs of the corresponding sub-network domains); after NSSMF of corresponding sub-network domain receives corresponding SLA, a sub-network slice template corresponding to the received SLA is created, and the created sub-network slice template is returned to NSMF; after receiving the subnet slice templates returned by the NSSMFs of the subnet domains, the NSMF creates an end-to-end network slice template according to the received subnet slice templates.

In practical application, when a plurality of sub-network slice templates and/or end-to-end network slice templates matched with the first information are selected from a network slice template library, the network slice templates can be matched more accurately based on different parameters contained in the first information; therefore, the efficiency of generating the end-to-end network slice instance can be improved, and the user experience is further improved. Specifically, the network slice template may be matched according to a slice type and a parameter of network service quality, which characterize the network slice and are included in the first information.

Based on this, in an embodiment, the method may further include:

determining second information according to the first information; the second information represents the slice type and the network service quality of the network slice;

selecting a plurality of sub-network slice templates and/or end-to-end network slice templates in a network slice template library that match the second information.

In practical application, the second information may include at least: the type of the network slice, the maximum user concurrency number of the network slice, the service area of the network slice, the end-to-end delay of the network slice, the mobility of the network slice, the isolation requirement of the network slice, the availability of the network slice, the guarantee level of the network slice and other parameters.

In practical application, if the type of the network slice (i.e., the type of the network slice required by the user) can be determined to be Enhanced Mobile Broadband (eMBB) according to the first information, the network slice template can be matched according to a parameter which is included in the first information and represents the capability of the network slice to provide the Mobile Broadband service.

Based on this, in an embodiment, the method may further include:

determining third information according to the first information; the third information represents the capability of the network slice to provide the mobile broadband service;

In practical applications, if the type of the network slice (i.e., the type of the network slice required by the user) can be determined to be Ultra-reliable and Low-Latency Communications (urrllc) according to the first information, the network slice template can be matched according to parameters, included in the first information, that characterize the capability of the network slice to provide Ultra-reliable and Ultra-Low Latency Communications.

Based on this, in an embodiment, the method may further include:

determining fourth information according to the first information; the fourth information represents the capability of the network slice to provide ultra-high-reliability ultra-low-delay communication;

selecting a plurality of sub-network slice templates and/or end-to-end network slice templates in a network slice template library that match the fourth information.

In practical application, the fourth information may include at least: network jitter, network lifetime, network reliability, data rate, payload size, traffic density, connection density, and service area size.

In actual application, when determining the configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates, under the condition that the sub-network domains of the end-to-end network slices corresponding to the sub-network slice templates are different, the specifically configured parameters are also different; in this way, the parameters can be automatically configured for each sub-network domain of the end-to-end network slice; the efficiency of generating the end-to-end network slice example is improved, and the user experience is further improved.

Based on this, in an embodiment, when determining the configuration parameter corresponding to each sub-network slice template in the plurality of sub-network slice templates, the method may further include:

In step 103, in actual application, after the NSMF obtains a plurality of sub-network slice templates, configuration parameters corresponding to each sub-network slice template, and an end-to-end network slice template, it can determine whether to create new resources according to online and/or offline resource conditions; if the judgment result is yes, and after the resource new establishment is completed, the NSMF can respectively send each sub-network slice template in the plurality of sub-network slice templates and the configuration parameters corresponding to the corresponding sub-network slice template to the NSSMF of the corresponding sub-network domain; after receiving the corresponding sub-network slicing template and the configuration parameters corresponding to the corresponding sub-network slicing template, the NSSMF of the corresponding sub-network domain generates an office data script according to the corresponding sub-network slicing template and the configuration parameters corresponding to the corresponding sub-network slicing template, and sends the generated office data script to the NSMF to start a data auditing process of the NSMF; after receiving the local data script submitted by the NSSMF of each sub-network domain, the NSMF starts a data auditing process, and sends an instruction for starting a corresponding sub-network slice instantiation process to the NSSMF of each sub-network domain after finishing data auditing; after receiving an instruction sent by the NSMF and used for starting the sub-network slice instantiation process, the NSSMF of the corresponding sub-network domain determines a corresponding sub-network slice instance according to the corresponding sub-network slice template and the configuration parameters corresponding to the corresponding sub-network slice template.

In step 104, in actual application, after the NSSMF of each sub-network domain obtains the corresponding sub-network slice instance, the obtained sub-network slice instance is sent to the NSMF; after receiving the sub-network slice instances sent by the NSSMFs of the sub-network domains, the NSMF determines an end-to-end network slice instance according to the received multiple sub-network slice instances, and the automatic instantiation of the end-to-end network slice is completed.

The network slice processing method provided by the embodiment of the invention obtains first information; the first information represents the service requirement of a user on the end-to-end network slice; determining a plurality of sub-network slice templates and an end-to-end network slice template consisting of the plurality of sub-network slice templates according to the first information, and determining configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates; each sub-network slice template of the plurality of sub-network slice templates corresponds to a sub-network domain of an end-to-end network slice; the configuration parameters comprise a first type of parameters and a second type of parameters; the first type of parameters are used for supporting information interaction between sub-network domains of the end-to-end network slice; the second type of parameters are used for supporting the network service of the sub-network domain corresponding to the corresponding sub-network slice template; determining a sub-network slice example corresponding to each sub-network slice template by using the configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates to obtain a plurality of sub-network slice examples; determining an end-to-end network slice example by using the end-to-end network slice template and the obtained multiple sub-network slice examples; therefore, automatic instantiation of the end-to-end network slice can be achieved, the efficiency of generating the end-to-end network slice instance is improved, and the user experience is further improved.

The present invention will be described in further detail with reference to the following application examples.

As shown in fig. 2, the method for processing a network slice according to the embodiment of the present application may include the following steps:

step 201: receiving and analyzing user requirements; step 202 is then performed.

Specifically, the process of receiving and analyzing the user requirement by the CSMF is the process of SLA analysis and decomposition; by analyzing the user requirements, the user requirements (i.e. the user requirement information) are converted into slice service requirement information (SLA, i.e. the first information) such as slice type, slice capability requirement, maximum user concurrency number of slices, slice service area, time delay, isolation requirement, and the like.

Here, the specific implementation process of step 201 is the same as the specific implementation process of step 101 in the processing method of network slices shown in fig. 1, and is not described here again.

Step 202: matching an end-to-end slicing template; step 203 is then performed.

Specifically, according to the slicing service requirement information determined in step 201, a slicing/sub-slicing template (the slicing template is the end-to-end network slicing template, and the sub-slicing template is the sub-network slicing template) is selected in the template library. The rules for selecting slice/sub-slice templates may include:

rule one is as follows: matching the slice template according to the basic condition parameters (namely the second information) in the slice service demand information; the base condition parameters may include at least: slicing type, slicing maximum user concurrency, slicing service area, end-to-end delay, mobility, isolation requirement, availability, guarantee level and other parameters.

Rule two: precisely matching the slice template according to the condition parameter (i.e., the third information) of the slice type (when the slice type is eMBB); the condition parameters may include at least: downlink rate, uplink rate, downlink capacity, uplink capacity, user density, UE speed, 5G SA signal coverage, etc.

Rule three: exactly matching the slice template according to the condition parameters (i.e., the above fourth information) of the slice type (when the slice type is urrllc); the condition parameters may include at least: jitter, lifetime, reliability, data rate, payload size, traffic density, connection density, service area size, etc.

Here, when the slice type is mtc, the selection of the slice/sub-slice template is not limited to the slice-generic condition parameter model.

Step 203: planning end-to-end network design; step 204 is then performed.

Specifically, after the end-to-end slice templates (including each sub-domain slice template) are matched, parameter planning configured by a cross-domain network (namely, the first type of parameter) and parameter planning configured by each domain (namely, the second type of parameter) are required for the next end-to-end slice instantiation, so as to support automatic pull-through of slice instantiation. The end-to-end network design plan can be divided into the following three parts based on the sub-network domains of the end-to-end network:

first, the design of the wireless sub-domain (i.e., wireless sub-network domain).

Specifically, parameter planning for cross-domain network configuration for a wireless sub-domain may include: and (3) planning network configuration parameters for intercommunication and interconnection of networks in various domains, such as parameters of VLAN ports, source IP, target IP and the like.

The parameter planning of the local domain for the wireless sub-domain may include: according to the requirements of the slicing service on the network requirement of the local domain and the requirements of the sub-slicing template, the configuration related to the local domain is planned, and the configuration specifically includes but is not limited to the following parameters:

design and planning of coverage area: the function presents the area to be covered by the slicing service and the actual covering condition (information such as SA/NSA covering, uncovering and weak covering) based on the GIS, and provides a reference basis for wireless resource construction. And automatically matching whether basic construction is needed or whether NSA/SA duplex modification and other engineering means are carried out according to the service coverage requirement and the actual coverage condition.

The related information can be presented in real time aiming at the established base station information: the method comprises the following steps of (1) including parameters such as base station identification, base station name, base station type, uplink flow, downlink flow, base station position, longitude and latitude, terminal access number, idle capacity (which can also be used as the terminal access number), idle capacity ratio and the like; and providing basis for site planning and selection.

Configuration of wireless design parameters: radio network delay, 5QI, etc.

According to the three wireless network planning means, the site selection and parameter planning of the wireless coverage are automatically generated based on the sub-slice template and the sub-slice requirements of the wireless network subdomain.

Second, the design of the core network sub-domain (i.e., the core network sub-network domain).

Specifically, the parameter planning for performing cross-domain network configuration for the core network sub-domain may include: and (3) planning network configuration parameters for intercommunication and interconnection of networks in various domains, such as parameters of VLAN ports, source IP, target IP and the like.

The parameter planning of the local domain for the core network sub-domain may include: according to the requirements of the slicing service on the network requirement of the local domain and the requirements of the sub-slicing template, the configuration related to the local domain is planned, and the configuration specifically includes but is not limited to the following parameters:

and (3) core network subdomain requirement analysis and presentation: the planning design of the core network is complex, and the design planning link of the subdomain of the core network comprehensively presents the slicing service requirements so as to support the network planning and design work of the subdomain. Specific presence information includes, but is not limited to: the method comprises the following parameters of a slicing service name, a slicing service type, a slicing service identifier, a slicing service area, an industry client name, a PLMN roaming range, a slicing maximum user concurrency number, time delay, mobility, isolation requirements, availability, a guarantee level, attribute display of different service types (eMBB, uRLLC and mMTC) and the like.

Setting network element conditions: setting network element screening rules aiming at the sub-slicing requirements and the sub-slicing templates of the domain, and setting conditions such as main/standby disaster tolerance requirements, group POOL planning requirements, system load upper limit, terminal access number upper limit, isolation and the like for each network element of a control plane. For each network element of the user plane, the conditions of time delay, uplink and downlink throughput upper limit, sinking and the like are also set.

Intelligent recommendation of resource pools and network elements: after the network element condition setting is completed, the resource pool and the virtual network element which accord with the screening condition can be automatically calculated and displayed.

Manual verification: meanwhile, the occupation conditions of all resources on each resource pool (the recommended resource pool can be marked prominently) can be presented, such as the occupation conditions of CPU, memory and storage. And simultaneously, the network elements in each resource pool are also displayed, and for each network element (the recommended network element can be marked), the information of slice sharing, system load, terminal access and the like of the network element can be graphically displayed. The method is used for supporting and improving the efficiency and the accuracy of manual verification.

Newly building a network element: if the network elements which meet the conditions are not automatically recommended according to the screening of the network elements, the function of newly building the network elements according to the network element conditions can be provided.

Third, the design and planning of the transport network sub-domains (i.e., transport sub-network domains).

Specifically, parameter planning for cross-domain network configuration for the transmission network sub-domain may include: network configuration parameters for interworking and interconnection of networks in various domains, such as network settings of an access layer, a convergence layer, a core layer and the like; parameter planning including, but not limited to, the following:

an access layer: designing network configuration parameters such as a base station, a network element, a port, a source IP, a VLAN ID, a routing target IP and the like;

setting a convergence layer: designing network configuration parameters such as the location of a machine room, a network element, a port, a source IP, a VLAN ID, a routing target IP and the like;

setting a core layer: and designing network configuration parameters such as the location of the machine room, network elements, ports, source IP, VLAN ID, routing target IP and the like.

Meanwhile, the parameter planning of the local domain for the transmission network sub-domain may include: according to the requirements of the slicing service on the network requirement of the local domain and the requirements of the sub-slicing templates, planning the relevant configuration of the local domain, such as the requirement configuration of logic isolation and hard isolation (namely physical isolation), the configuration planning of a Flexe hard channel and other parameter planning designs.

Here, the specific implementation process of step 202 to step 203 is the same as the specific implementation process of step 102 in the processing method of network slices shown in fig. 1, and is not described here again.

Step 204: judging whether to create new resources according to the online/offline resource condition; step 205 is then performed.

Specifically, after the slice end-to-end planning design, whether to newly build a resource is selected according to the online/offline resource investigation condition.

Step 205: generating local data scripts according to templates and parameters of the end-to-end planning design of the slices in each domain; step 206 is then performed.

Specifically, after the resource creation is completed, the slice manager (i.e., NSMF) issues the template and parameters of the end-to-end slice planning design to each domain sub-slice manager (i.e., NSSMF), and each domain generates a local data script according to the template and parameters and automatically submits the local data script to the slice manager (i.e., NSMF) to start a data auditing link.

Step 206: data auditing is carried out, and a slice instantiation process is started; step 207 is then performed.

Specifically, after the data is checked, the slice manager (NSMF) issues the templates and the planning parameters of each sub-field to each sub-field, and starts the instantiation process of the sub-slices of each sub-field.

Step 207: performing a sub-slice instantiation process of each sub-domain; step 208 is then performed.

Here, the specific implementation process of step 204 to step 207 is the same as the specific implementation process of step 103 in the processing method of network slices shown in fig. 1, and is not described here again.

Step 208: the end-to-end slice instantiation process is complete.

Specifically, after the instantiation process of each domain sub-slice is finished, the instantiation result (information such as network element information of each sub-domain, sub-slice instance ID) is returned to the slice manager (NSMF); the end-to-end slice instantiation process is complete.

Here, the specific implementation process of step 208 is the same as the specific implementation process of step 104 in the processing method of network slices shown in fig. 1, and is not described here again.

In step 202, there may be a case where there is no available template in the template library when actually applying; at this point, a slice/sub-slice template needs to be created. Based on this, in another application scenario of the present application embodiment, as shown in fig. 3, the method for processing a network slice provided by the present application embodiment may include the following steps:

step 301: receiving and analyzing user requirements; step 302 is then performed.

Here, the specific implementation process of step 301 is the same as that of step 201 described above and step 101 in the processing method of network slices shown in fig. 1, and is not described here again.

Step 302: matching the slicing/sub-slicing templates in the existing template library according to the slicing service requirement; when no template is available in the template library, step 303 is performed.

Here, the specific implementation process of step 301 is the same as the specific implementation process of step 202, and is not described herein again.

Step 303: newly building a slicing/sub-slicing template; step 303 is then performed.

Specifically, if there is no available slice/sub-slice template in the existing slice template library, a slice/sub-slice template needs to be newly created according to the received and analyzed slice service requirement. The new construction process is divided into two modes: direct mode and indirect mode.

The direct mode is suitable for the case that a slice manager (NSMF) and a sub-slice manager (NSSMF) are realized in a unified functional node; the specific implementation process is as follows:

the slice manager (NSMF) continues to decompose the slice service demand information into network demands (decomposed SLAs, namely the demand information corresponding to each sub-network domain) of each domain sub-network of the slice of the core network, the wireless network, the transmission network and the IP network according to the received and analyzed slice service demand information, and matches or creates a sub-slice template of each professional domain according to the demands of each professional domain; and generating an end-to-end slicing template (including core network, wireless, transmission and other professional networks) of the slicing network according to the sub-slicing templates generated in each domain.

The indirect mode is suitable for the case where a slice manager (NSMF) and a sub-slice manager (NSSMF) are hierarchically arranged; the specific implementation process is as follows:

firstly, a slice manager (NSMF) continuously decomposes the requirements into the network requirements of each domain subnet of slices of a core network, a wireless network, a transmission network and an IP network according to the received and analyzed slice service requirements; sending the decomposed network requirements of each subdomain to a sub-slice manager (NSSMF) of each subdomain, and sending sub-slice template request information; the sub-slice manager (NSSMF) for each sub-domain matches or creates sub-slice templates for the domain based on the network requirements resolved to the domain.

Then, the sub-slice manager (NSSMF) of each sub-domain returns the matched or newly created sub-slice template to the slice manager (NSMF); and the slicing manager (NSMF) generates end-to-end slicing templates (including core network, wireless, transmission and other professional networks) of the slicing network according to the sub-slicing templates generated by each domain.

Step 304: planning end-to-end network design; step 305 is then performed.

Here, the specific implementation procedure of step 304 is the same as that of step 203 described above; meanwhile, the specific implementation process of step 302 to step 304 is the same as the specific implementation process of step 102 in the processing method of network slices shown in fig. 1, and is not described here again.

Step 305: judging whether to create new resources according to the online/offline resource condition; step 306 is then performed.

Step 306: generating local data scripts according to templates and parameters of the end-to-end planning design of the slices in each domain; step 307 is then performed.

Step 307: data auditing is carried out, and a slice instantiation process is started; step 308 is then performed.

Step 308: performing a sub-slice instantiation process of each sub-domain; step 309 is then performed.

Here, the specific implementation process of step 305 to step 308 is the same as the specific implementation process of step 204 to step 207 and the specific implementation process of step 103 in the network slice processing method shown in fig. 1, and is not described herein again.

Step 309: the end-to-end slice instantiation process is complete.

Here, the specific implementation process of step 309 is the same as the specific implementation process of step 208 and the specific implementation process of step 104 in the processing method of network slices shown in fig. 1, and is not described herein again.
