Detailed ways

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments of the description.

In related technologies, after users put forward requirements such as business type, service scope, performance index requirements, and special functional characteristics, R&D personnel can implement the overall design of end-to-end network slicing based on the following two methods:

The first method is the blueprint design method.

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

The second method is the parameter configuration method.

Specifically, a plurality of application scenarios can be determined according to the user's needs, and the service type and configuration parameters of the corresponding network slice can be determined according to each determined application scenario; the configuration parameters represent the network resources, computing resources and Storage resources; according to the service type and configuration parameters of the corresponding network slice, a corresponding network slice instance is generated, and a network slice instance corresponding to each application scenario in the multiple application scenarios is obtained.

However, when implementing the instantiation of end-to-end network slicing in the above two ways, there are the following drawbacks:

First, when the automatic instantiation of network slices is implemented based on the above method 1, since there is no uniform parameter configuration for each sub-network slice included in the network slice, there may be situations where information exchange cannot be performed between the sub-network slices.

Second, when the automatic instantiation of network slices is implemented based on the above method 2, for multiple application scenarios, if the application scenarios are different, the service types of the network slices corresponding to the corresponding application scenarios are also different, that is, the corresponding application scenarios correspond to The parameters that need to be configured for different network slices are different; therefore, it is necessary to configure parameters for the network slices corresponding to each application scenario, which results in a large workload, low efficiency in generating network slice instances, and poor user experience.

Based on this, in various embodiments of the present invention, a plurality of sub-network slice templates and end-to-end network slice templates are determined according to user requirements, and configuration parameters corresponding to each sub-network slice template are determined, and each sub-network slice template is used. and corresponding configuration parameters, generate corresponding sub-network slice instances, and use the end-to-end network slice template and the generated multiple sub-network slice instances to generate corresponding end-to-end network slice instances. Automatic instantiation improves the efficiency of generating end-to-end network slice instances, thereby improving user experience.

An embodiment of the present invention provides a method for processing network slices. As shown in FIG. 1 , the method includes the following steps:

Step 101: Obtain first information; the first information represents a user's service requirements for end-to-end network slicing;

Step 102: According to the first information, determine a plurality of sub-network slicing templates and an end-to-end network slicing template composed of the plurality of sub-network slicing templates, and determine that each sub-network slicing template in the plurality of sub-network slicing templates corresponds to configuration parameters;

Here, each sub-network slice template in the plurality of sub-network slice templates corresponds to a sub-network domain of an end-to-end network slice; the configuration parameters include first-type parameters and second-type parameters; the first-type parameters use information exchange between sub-network domains that support end-to-end network slices; the second type of parameters is used to support network services of sub-network domains corresponding to corresponding sub-network slice templates;

Step 103: Using the configuration parameters corresponding to each sub-network slice template in the plurality of sub-network slice templates, determine the sub-network slice instance corresponding to each sub-network slice template, and obtain a plurality of sub-network slice instances;

Step 104: Determine an end-to-end network slice instance by using the end-to-end network slice template and the obtained multiple sub-network slice instances.

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

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

Receive user demand information;

The first information is determined according to the received user requirement information.

Specifically, users can order end-to-end network slices through CSMF, and submit their own demand information for end-to-end network slices in CSMF, that is, CSMF receives user demand information; the user demand information may include online user requirements, network bandwidth requirements requirements, delay requirements, etc.; after receiving the user requirement information, CSMF performs a Service Level Agreement (SLA, Service Level Agreement) analysis on the user requirement information to determine the first information; CSMF analyzes the user requirement information The meaning of performing SLA analysis on the information is: CSMF converts the user requirement information into SLA, and the SLA defines the communication service type of the end-to-end network slice subscribed by the user. Here, the SLA converted from the user demand information is the first information; the first information may include the type of network slice, the capability requirement of the network slice, the maximum concurrent number of users of the network slice, the service area of the network slice, Parameters such as network slicing delay and network slicing isolation requirements.

In step 102, in practical application, after the CSMF obtains the first information, the CSMF may send the first information to the NSMF, and the NSMF determines a plurality of sub-network slice templates and the plurality of sub-networks according to the first information An end-to-end network slice template composed of slice templates. In addition, a network slice template library can be preset in the NSMF, and after receiving the first information sent by the CSMF, the NSMF can select multiple sub-network slice templates and end-to-end network slice templates that match the first information in the network slice template library. End-to-end network slice templates; in this way, the efficiency of generating end-to-end network slice instances can be improved, thereby improving user experience.

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:

A plurality of sub-network slice templates and end-to-end network slice templates that match the first information are selected from the network slice template library.

In practical application, there may not exist multiple sub-network slicing templates and/or end-to-end network slicing templates matching the first information in the network slicing template library; in this case, multiple sub-networks corresponding to the first information may be created slice templates and/or end-to-end network slice templates, and store the created multiple sub-network slice templates and/or end-to-end network slice templates 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:

When a plurality of sub-network slice templates and/or end-to-end network slice templates matching the first information are not found in the network slice template library, create a plurality of sub-network slice templates and/or end-to-end network slice templates corresponding to the first information end-to-end network slice templates, and store the created multiple sub-network slice templates and/or end-to-end network slice templates in the network slice template library.

In practical application, the following three situations may exist in the process that the NSMF selects multiple sub-network slice templates and end-to-end network slice templates that match the first information in the network slice template library.

Case 1: There is an end-to-end network slice template matching the first information in the network slice template library, but there are no multiple sub-network slice templates matching the first information. In this case, an end-to-end network slice template matching the first information may be obtained from a network slice template library, and a plurality of sub-network slice templates matching the first information may be created according to the obtained end-to-end network slice template.

Case 2: There are multiple sub-network slice templates matching the first information in the network slice template library, but there is no end-to-end network slice template matching the first information. In this case, multiple 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 according to the acquired multiple sub-network slice templates. Here, when multiple sub-network slicing templates matching the first information are obtained from the network slicing template library, the corresponding sub-network domain of each of the multiple sub-network domains of the end-to-end network slicing may be determined according to the first information first. According to the requirement information corresponding to each sub-network domain, the corresponding sub-network slice template matching the corresponding requirement information is obtained from the network slice template library. In practical application, the first information may be an SLA, and determining the demand information corresponding to each sub-network domain in the multiple sub-network domains of the end-to-end network slice according to the first information may be decomposing the SLA. ; that is, decompose the SLA into the SLA corresponding to each of the multiple sub-domains of the end-to-end network slice.

Case 3: There are no multiple sub-network slice templates and end-to-end network slice templates matching the first information in the network slice template library. At this time, the requirement information corresponding to each sub-network domain in the multiple sub-network domains of the end-to-end network slice may be determined according to the first information, and the corresponding sub-network domain is created by using the requirement information corresponding to each sub-network domain. Sub-network slicing templates to obtain multiple sub-network slicing templates matching the first information; and then using the plurality of sub-network slicing templates to create end-to-end network slicing templates that match the first information.

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

Specifically, using the direct mode to create multiple sub-network slice templates and end-to-end network slice templates corresponding to the first information may include: NSMF decomposing the SLA (that is, the first information); that is, decomposing the SLA It is decomposed into the SLA corresponding to each sub-network domain in the multiple sub-network domains of the end-to-end network slice (that is, the demand information corresponding to each sub-network domain), and obtains the sub-network domains such as core network, wireless, transmission, and IP network. SLA; then according to the SLAs of the core network, wireless, transmission, IP network and other sub-network domains, respectively create sub-network slice templates corresponding to the core network, wireless, transmission, IP network and other sub-network domains; finally, according to the created core network, Sub-network slice templates corresponding to sub-network domains such as wireless, transmission, and IP networks are used to create end-to-end network slice templates.

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

Specifically, using the indirect mode to create multiple sub-network slice templates and end-to-end network slice templates corresponding to the first information may include: NSMF decomposing the SLA (that is, the first information); that is, decomposing the SLA It is decomposed into the SLA corresponding to each sub-network domain in the multiple sub-network domains of the end-to-end network slice (that is, the demand information corresponding to each sub-network domain), and obtains the sub-network domains such as core network, wireless, transmission, and IP network. SLA, and send the obtained SLAs of the core network, wireless, transmission, IP network and other sub-network domains to the NSSMF of the core network, wireless, transmission, IP network and other sub-network domains (here, you can send the SLA containing the corresponding sub-network domain). The sub-network slice template request message of the SLA is sent to the NSSMF of the corresponding sub-network domain); after receiving the corresponding SLA, the NSSMF of the corresponding sub-network domain creates a sub-network slice template corresponding to the received SLA, and returns the created sub-network slice template. To the NSMF; after the NSMF receives the sub-network slicing templates returned by the NSSMF of each sub-network domain, it creates an end-to-end network slicing template according to the received multiple sub-network slicing templates.

In practical application, when selecting multiple sub-network slice templates and/or end-to-end network slice templates that match the first information in the network slice template library, it can be more accurate based on different parameters contained in the first information. matching network slice templates; in this way, the efficiency of generating end-to-end network slice instances can be improved, thereby improving user experience.

In practical application, if the type of network slice (that is, the type of network slice required by the user) can be determined to be enhanced mobile broadband (eMBB, Enhanced Mobile Broadband) according to the first information, it can also be determined according to the representation included in the first information. The parameters of the network slice's ability to provide mobile broadband services match the network slice template.

Automatic instantiation improves the efficiency of generating end-to-end network slice instances, thereby improving user experience.

The present invention will be further described in detail below in conjunction with application examples.

As shown in FIG. 2 , the method for processing network slices provided by this application embodiment may include the following steps:

Step 201: Receive and analyze user requirements; then step 202 is performed.

Specifically, the process of receiving and analyzing user requirements by CSMF is the process of SLA analysis and decomposition; by analyzing user requirements, the user requirements (that is, the above-mentioned user requirement information) are converted into slice types, slice capability requirements, and slice maximum user concurrency. Slice service requirement information (SLA, that is, the above-mentioned first information) such as number of slices, slice service area, delay, and isolation requirements.

Here, the specific implementation process of step 201 is the same as the specific implementation process of step 101 in the network slicing processing method shown in FIG. 1 , and details are not described here.

Step 202: Match the end-to-end slice template; then step 203 is performed.

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

Rule 1: Match the slice template according to the basic condition parameters (that is, the above-mentioned second information) in the slice service requirement information; Mobility, isolation requirements, availability, assurance level and other parameters.

Rule 2: Exactly match the slice template according to the conditional parameters (that is, the third information) of the slice type (when the slice type is eMBB); the conditional parameters may at least include: downlink rate, uplink rate, downlink capacity, uplink capacity, user density, Parameters such as UE speed and 5G SA signal coverage.

Here, it should be noted that when the slice type is mMTC, the selection of slice/sub-slice templates is not limited to the slice general condition parameter model.

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

Specifically, after matching the end-to-end slicing template (including each sub-domain slicing template), the parameters of the cross-domain network configuration (that is, the above-mentioned first type of parameters) should be planned for the next end-to-end slicing instantiation and each domain itself. The configured parameters (that is, the above-mentioned second type of parameters) are planned to support the automatic pull-through of slice instantiation. The end-to-end network design planning can be divided into the following three parts based on the sub-network domains of the end-to-end network:

First, the design and planning of the wireless sub-domain (ie, the wireless sub-network domain).

Specifically, parameter planning for cross-domain network configuration for wireless sub-domains may include: network configuration parameter planning for network interconnection in each domain, such as parameters such as VLAN ports, source IP, and destination IP.

The parameter planning for the wireless sub-domain can include: planning the configuration related to the local domain according to the network requirements of the slicing service and the sub-slice template requirements, including but not limited to the following parameters:

Coverage area design and planning: Based on GIS, this function presents the area to be covered by the slice service and the actual coverage (SA/NSA coverage, non-coverage, weak coverage, etc.), providing a reference for wireless resource construction. And according to the business coverage requirements and the actual coverage, it automatically matches whether infrastructure construction or whether to carry out NSA/SA dual transformation and other engineering means.

Relevant information can be presented in real time for the information of the established base station: including base station identification, base station name, base station type, uplink traffic, downlink traffic, base station location, longitude and latitude, terminal access number, idle capacity (can also be used as terminal access number), idle Parameters such as capacity ratio; it can provide a basis for site planning and selection.

Wireless design parameter configuration: wireless network delay, 5QI and other parameters.

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

Second, the design and planning of the core network sub-domain (ie, the core network sub-network domain).

Specifically, parameter planning for cross-domain network configuration for core network sub-domains may include: network configuration parameter planning for network interconnection in each domain, such as VLAN port, source IP, destination IP and other parameters.

The parameter planning for the core network sub-domain may include: planning the configuration related to this domain according to the network requirements of the slice service and the sub-slice template requirements, including but not limited to the following parameters:

Analysis and presentation of core network sub-domain requirements: The planning and design of the core network is relatively complex. The core network sub-domain design and planning process will comprehensively present the slicing service requirements to support the network planning and design of this domain. The specific presentation information includes but is not limited to: slice service name, slice service type, slice service identifier, slice service area, industry customer name, PLMN roaming range, maximum number of concurrent users of slice, delay, mobility, isolation requirements, availability, guarantee Level, and different attribute display parameters for different service types (eMBB, uRLLC, and mMTC).

NE condition setting: According to the sub-slice requirements and sub-slice templates of the domain, set the NE filtering rules. For each NE on the control plane, you need to set the master and backup disaster recovery requirements, group POOL planning requirements, and system load upper limit , the upper limit of terminal access, whether to isolate or not, etc. For each network element on the user plane, conditions such as delay, upper limit of uplink and downlink throughput, and whether to sink or not must be set.

Intelligent recommendation of resource pools and network elements: After the network element conditions are set, the resource pools and virtual network elements that meet the filtering conditions can be automatically calculated and displayed.

Manual verification: At the same time, the occupancy of each resource on each resource pool (recommended resource pools will be highlighted) can be displayed, such as the occupancy of CPU, memory and storage. At the same time, it also displays the network elements in each resource pool. For each network element (recommended network elements will be highlighted), information such as slice sharing, system load, and terminal access of the network element can be displayed graphically. To support and improve the efficiency and accuracy of human verification.

New NE: If no qualified NEs are automatically recommended according to NE filtering, the function of creating NEs according to NE conditions is provided.

Third, the design and planning of the transmission network sub-domain (ie, the transmission sub-network domain).

Specifically, parameter planning for cross-domain network configuration for transmission network sub-domains may include: network configuration parameters for interconnection between networks in each domain, such as network settings such as access layer, aggregation layer, and core layer; including but not limited to The following parameters are planned:

Access layer: design of network configuration parameters such as base station, network element, port, source IP, VLAN ID, and routing destination IP;

Aggregation layer settings: design of network configuration parameters such as the location of the computer room, network elements, ports, source IP, VLAN ID, routing destination IP;

Core layer settings: design of network configuration parameters such as the location of the computer room, network elements, ports, source IP, VLAN ID, and routing destination IP.

At the same time, planning the parameters of the sub-domain of the transmission network can include: planning the configuration related to the domain, such as logical isolation and hard isolation (ie, physical isolation), according to the network requirements of the slicing service and the requirements of the sub-slice template. Planning and design of parameters such as the required configuration of the FlexE hard channel and the configuration planning of the FlexE hard channel.

Here, the specific implementation process of steps 202 to 203 is the same as the specific implementation process of step 102 in the network slicing processing method shown in FIG. 1 , and details are not repeated here.

Step 204: Determine whether to create a new resource according to the online/offline resource situation; then step 205 is executed.

Specifically, after the end-to-end planning and design of slicing, whether to create a new resource will be selected according to the online/offline resource survey.

Step 205 : each domain generates an office data script according to the template and parameters of the end-to-end planning and design of the slice; then step 206 is executed.

Specifically, after the resource creation is completed, the slice manager (ie NSMF) will deliver the template and parameters of the end-to-end slice planning and design to the sub-slice manager (ie NSSMF) of each domain, and each domain will generate office data according to the template and parameters. The script automatically submits the slice manager (ie NSMF) to start the data review process.

Step 206 : data review, start the slice instantiation process; then step 207 is performed.

Specifically, after the data review is completed, the slice manager (NSMF) delivers the templates and planning parameters of each subdomain to each subdomain, and starts the instantiation process of the subslice of each subdomain.

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

Here, the specific implementation process of steps 204 to 207 is the same as the specific implementation process of step 103 in the network slicing processing method shown in FIG. 1 , and details are not repeated here.

Step 208: The end-to-end slice instantiation process is completed.

Specifically, after the instantiation process of sub-slices of each domain is completed, the instantiation results (network element information of each sub-domain, sub-slice instance ID and other information) are returned to the slice manager (NSMF); the end-to-end slice instantiation process Finish.

Here, the specific implementation process of step 208 is the same as the specific implementation process of step 104 in the network slicing processing method shown in FIG. 1 , and details are not repeated here.

Here, the specific implementation process of step 301 is the same as the specific implementation process of the above-mentioned step 202, and details are not repeated here.

Step 303: Create a new slice/sub-slice template; then step 303 is performed.

Specifically, if there is no available slice/sub-slice template in the existing slice template library, you need to create a new slice/sub-slice template according to the received and parsed slice service requirements. The new process is divided into two modes: direct mode and indirect mode.

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

According to the received and parsed slice service requirement information, the slice manager (NSMF) continues to decompose it into the network requirements (decomposed SLA, that is, the corresponding sub-network domains of the above-mentioned sub-networks) of the slices to the core network, wireless, transmission, and IP network. According to the demand information of each professional domain), the sub-slice template of each professional domain is matched or created according to the requirements of each professional domain; according to the sub-slice template generated by each domain, the end-to-end slicing template of the slicing network (including core network, wireless, transmission and other professional domains is generated) network).

The indirect mode is suitable for the hierarchical setting of slice manager (NSMF) and sub-slice manager (NSSMF); the specific implementation process is as follows:

First, the slice manager (NSMF) continues to decompose the network requirements of the sliced sub-networks into the core network, wireless, transmission, and IP network according to the received and parsed slice service requirements; The requirements are sent to the sub-slice manager (NSSMF) of each sub-domain, and the sub-slice template request information is sent; the sub-slice manager (NSSMF) of each sub-domain matches or creates a new domain according to the network requirements decomposed into the professional domain sub-slice template.

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

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

Here, the specific implementation process of step 304 is the same as the specific implementation process of the above-mentioned step 203; meanwhile, the specific implementation process of steps 302 to 304 is the same as the specific implementation process of step 102 in the processing method of network slicing shown in FIG. More to say.

Step 305: Determine whether to create a new resource according to the online/offline resource situation; then step 306 is executed.

Step 306 : each domain generates an office data script according to the template and parameters of the end-to-end planning and design of the slice; then step 307 is executed.

Step 307: Data review, start the slice instantiation process; then step 308 is performed.

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

Here, the specific implementation process of steps 305 to 308 is the same as the specific implementation process of the above-mentioned steps 204 to 207 and the specific implementation process of step 103 in the network slicing processing method shown in FIG. 1 , and details are not repeated here.

Step 309: The end-to-end slice instantiation process is completed.

Here, the specific implementation process of step 309 is the same as the specific implementation process of the above-mentioned step 208 and the specific implementation process of step 104 in the network slice processing method shown in FIG. 1 , and details are not repeated here.
