The present application claims priority to Chinese Patent Application No. 200910687654.X, entitled "A Network Slice Management Method and Apparatus", filed on August 11, 2017, the entire contents of which are incorporated by reference. In this application.

Technical field

The present application relates to the field of communications technologies, and in particular, to a network slice management method and apparatus.

Background technique

With the development of communication technologies, the types of communication services are gradually increasing, and the requirements of different communication services for network performance such as mobility, security, capacity, delay and reliability are significantly different. If a specific network is established for each communication service, it can meet the needs of various communication services, but the cost is high. If the communication services of different requirements are carried on the same network, the network is complex and the operation and maintenance is difficult. Due to the large difference in the requirements of different communication services, the quality of service (QoS) of the communication service may be degraded.

In order to solve the above problem, the concept of network slice (NS) is introduced in the fifth generation mobile communication system (5G) to cope with the difference in network performance requirements of different communication services. A network slice is a combination of multiple network functions and their resources (such as storage resources, computing resources, etc.) and can fulfill specific communication service requirements. The 5G communication network contains a large number of network slices, and each network slice can be regarded as a logical network that completes a communication service.

The network slice can be a complete end-to-end network including the terminal, the access network, the transmission network, the core network and the application server, and can provide a complete communication service with certain network capabilities; the network slice can also be the above terminal and interface. Any combination of network access, transport network, core network and application server.

A network slice can be divided into several network slice subnet instances (NSSIs). The network slicing subnet does not need to provide end-to-end complete network services. The network slicing subnet can be a collection of network functions of the same device vendor in the network slice, or a collection of network functions divided by domain, such as a core network. A network slicing subnet, an access network network slicing subnet, or a collection of other ways, such as a deployment location. Network slice subnets may be shared by multiple network slices.

Network function (NF) is a processing function in the network that defines functional behaviors and interfaces. Network functions can be implemented by dedicated hardware, or by running software on dedicated hardware, or in general. The hardware platform is implemented in the form of virtual functions. Therefore, from the perspective of implementation, network functions can be divided into physical network functions and virtual network functions; from the perspective of use, network functions can be divided into dedicated network functions and shared network functions, specifically, for multiple network slices (or In terms of network slicing subnets, different network functions can be used independently. This network function is called a dedicated network function and can share the same network function. This network function is called a shared network function.

Network slices are created and managed by the network slice management system. A network slice management system can create multiple network slices and manage them at the same time, such as monitoring network performance during network segmentation, fault management, and modifying configuration parameters. As shown in FIG. 1, the network slice management system may include: a communication service management function (CSMF), a network slice management function (NSMF), and a network slice subnet management function. Function, NSSMF). Among them, CSMF is mainly used to convert the communication service related requirements of operators and/or third-party customers into parameter information of network slicing; NSMF is mainly used to manage the life cycle, performance, faults, etc. of network slicing; NSSMF mainly It is used to manage the life cycle, performance, faults, etc. of the network slicing subnet.

However, in the prior art, the communication interface between the CSMF and the NSMF is not standardized, and how to communicate between the CSMF and the NSMF, thereby implementing the NSMF to manage the network slice, is an urgent problem to be solved.

Detailed ways

The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

FIG. 2 is a schematic structural diagram of an application scenario provided by an embodiment of the present application.

Specifically, the CSMF is mainly used to: convert the communication service related requirements of the operator and/or the third party into the parameter information of the network slice, and send the parameter information of the network slice to the NSMF through the interface with the NSMF, from the NSMF. Obtain management data of the network slice (such as describing performance data of the network slice, fault data of the network slice, etc.), and generate management data of the communication service (such as performance data describing the communication service, fault data of the communication service, etc.), receiving the operator and / or third-party customer subscription requirements for network slice management data and / or communication business management data.

The NSMF is mainly used to: receive parameter information of a network slice sent by the CSMF; manage the life cycle of the network slice (for example, create a new network slice, or terminate an established network slice, etc.), performance, fault, etc. Cycle, performance, fault management abbreviation management), optionally, may also send a network slice subnet management request to each NSSMF.

In the architecture shown in FIG. 2, CSMF and multiple NSMFs may serve one carrier; or CSMF may serve one carrier, but the multiple NSMFs may serve multiple operators; or, CSMF also It may not be limited to a certain operator, but may be controlled and managed by a third party, and the multiple NSMFs may serve one operator or multiple operators. This application does not limit this.

Figure 2 exemplarily shows an architecture diagram of a CSMF establishing a connection with multiple NSMFs. However, in practical applications, an NSMF can also be connected to multiple CSMFs, which can include CSMFs belonging to the same carrier as the NSMF. It may also include a CSMF that belongs to a different operator from the NSMF, or may also include a CSMF provided by a third party, which is not limited in this application. In addition, a CSMF can also be connected to only one NSMF.

The embodiment of the present application provides a network slice management method and device, which are used to implement communication between the CSMF and the NSMF, thereby implementing network slice management.

FIG. 3 is a schematic flowchart of a network slice management method according to an embodiment of the present disclosure. As shown in the figure, the method may include the following steps:

Step 301: The CSMF determines first network slice parameter information for the first NSMF.

The first network slice parameter information is used to request the first NSMF to manage the network slice managed by itself. Specifically, the first network slice parameter information may be used to request the first NSMF to create a network slice according to the parameter information, or may be used to request the first NSMF to modify parameters of the existing network slice, and may also request that the NSMF termination has been performed. Establish a network slice, etc.

As described above, the CSMF can convert the related requirements of the communication service into the parameter information of the network slice. In the above step 301, the CSMF can determine the first network slice parameter information for the first NSMF according to the relevant requirements of the communication service. In addition, the CSMF may determine the first network slice parameter information for the first NSMF according to the network slice parameter information that the first NSMF can support, the change of the network environment, the change of the parameters of the network slice managed by the other NSMF, and the like.

In a possible implementation manner, the foregoing first network slice parameter information may include one or any combination of the following information:

Service level agreement (SLA);

Network KPI, where network KPI can further include one or any combination of the following information: latency, coverage, capacity, throughput, reliability (reliability), report success ratio, command success ratio, etc.

The network slice type may include an enhanced mobile broadband (eMBB), an ultra reliable low latency communications (URLLC), a massive internet of things (MIoT), and the like;

Quality of service (QoS);

Network topology (topology);

Resource requirements;

Network function related requirements, such as network function type, capacity (refers to the capacity of a single network function), location (such as IP address, physical address or port number, etc.), capabilities, etc.

Step 302: The CSMF sends the first network slice parameter information to the first NSMF.

Step 303: The first NSMF manages the network slice according to the first network slice parameter information.

In the above method, the CSMF sends the first network slice parameter information determined by the first NSMF to the first NSMF, so that the first NSMF can manage the network slice managed by the first NSMF according to the first network slice parameter information. The communication between CSMF and NSMF enables the management of network slices. For example, the CSMF may convert the relevant requirements of the communication service into network slice parameter information, and send the information to the first NSMF, so that the first NSMF creates a new network slice according to the network slice parameter information, or the existing network slice parameter information. to modify.

In order to ensure the related requirements of the communication service, in a possible implementation manner, the CSMF can communicate with the network slice managed by the NSMF connected thereto, and obtain performance parameters of each network slice to determine whether it can be determined. Meet the needs of communication services.

Specifically, the CSMF may acquire performance parameters of the network slice managed by the first NSMF, and determine performance parameters of the communication service that the first NSMF managed network slice can provide according to the performance parameters.

Further, in order to ensure the related requirements of the communication service, the CSMF may set a preset range of performance parameters of the communication service that the first NSMF-managed network slice can provide, that is, the performance of the communication service that can be provided by the first NSMF-managed network slice. When the parameter is in the preset range, it indicates that the currently provided communication service can meet the relevant requirements of the communication service. Otherwise, it indicates that the currently provided communication service cannot meet the relevant requirements of the communication service, and the related requirements of the communication service need to be adjusted, thereby The parameters of the network slice managed by the first NSMF are adjusted.

When the CSMF determines that the value of the performance parameter of the communication service that can be provided by the network slice managed by the first NSMF exceeds a preset range, the CSMF may modify the parameters of the network slice managed by the first NSMF, that is, determine the first NSMF. A network slicing parameter information to enable timely adjustment of the network slice managed by the first NSMF to enable it to provide the performance required for the communication service.

In a possible implementation manner, after the network slice parameter information managed by the NSMF changes, the adjustment information may be sent to the CSMF connected thereto, where the adjustment information includes parameter adjustment information of the network slice managed by the NSMF. For example, due to changes in the network environment, the parameters of the network slice managed by the NSMF are changed, and the NSMF may send the parameter adjustment information of the network slice to the CSMF connected thereto; or, in the case of multiple CSMFs connected by one NSMF, if A CSMF requests the NSMF to adjust the parameters of the network slice, and the NSMF may, after adjustment, send the parameter adjustment information of the network slice to other CSMFs. The adjustment information may be sent to the CSMF as an independent information, or may be carried in other information and sent to the CSMF.

The CSMF may also adjust the network slice parameter information managed by the first NSMF after receiving the adjustment information sent by the other NSMF, that is, determine the first network slice parameter information for the first NSMF according to the adjustment information sent by the other NSMF, to ensure communication. The related needs of the service can still be met.

For example, the communication service managed by the CSMF is jointly provided by the network slice managed by the first NSMF and the network slice managed by the second NSMF, wherein the bandwidth of the network slice 1 managed by the first NSMF is 50M, and the slice 2 of the network slice managed by the second NSMF The bandwidth of the network is 100M. Due to the influence of the network environment, the bandwidth of the network slice 2 managed by the second NSMF is reduced to 50M. After receiving the adjustment information sent by the second NSMF, the CSMF may request the first NSMF to slice the network it manages. The bandwidth is adjusted to 100M to ensure that the quality of the communication service provided by the first NSMF and the second NSMF remains unchanged.

Similarly, if the network slice parameter information sent by the first NSMF is changed, the first NSMF may also send the adjustment information to the CSMF, so that the CSMF can perform parameter modification on the network slice managed by the other NSMF to meet the communication service. Related needs.

In combination with any of the foregoing embodiments, the CSMF may first negotiate with the first NSMF to determine whether the first NSMF can support the network slice parameters required by the CSMF for the first NSMF before determining the first network slice parameter information for the first NSMF. .

Specifically, the CSMF may send a first request to the first NSMF, where the first request includes second network slice parameter information, configured to query whether the first NSMF can support the second network slice parameter information. The second network slice parameter information may be the network slice parameter information that is determined by the CSMF according to the related requirements of the communication service, and may be the expected first NSMF pair determined by the CSMF according to the related requirements of the communication service. Parameter adjustment information of the network slice; or, when the CSMF obtains the communication service performance parameter that can be provided by the network slice managed by the first NSMF, it is expected that the first NSMF adjusts the parameter of the existing network slice; or After the CSMF receives the parameter adjustment information sent by the second NSMF, it determines the parameter adjustment information of the desired first NSMF pair existing network slice.

Optionally, the second network slice parameter may be sent by using a separate signaling, that is, the first request is only used to negotiate with the first NSMF, and whether the first NSMF can support the second network slice parameter information; or, the second The network slice parameters may also be carried in other signaling, which is not limited in this application.

After receiving the first request, the first NSMF sends a first response to the CSMF, where the first response includes indication information indicating whether the first NSMF can support the second network slice parameter.

In some embodiments, the indication information may only indicate whether the second network slice parameter can be supported. For example, the indication information may be represented by one bit. If the value of the bit is 1, it indicates that the first NSMF can support the second network slice parameter. If the value on the bit is 0, the first NSMF cannot support. Second network slice parameter.

In the foregoing manner, the signaling overhead occupied by the indication information is small, but may cause the negotiation process to be performed multiple times. For example, the CSMF expects the first NSMF to create a network slice with a bandwidth of 200M according to the related requirements of the communication service, and asks whether the first NSMF supports the creation of a network slice with a bandwidth of 200M through the first request, but the first NSMF only supports the creation of 100M bandwidth. The network is sliced, so the first response of the first NSMF reply indicates that it is not supported. Then the CSMF modifies the parameter information in the first request, and asks again whether the first NSMF supports the creation of a network slice of 150M bandwidth, and the first NSMF reply again does not support. Therefore, the CSMF needs to modify the parameter information in the first request again and ask again if the first NSMF can support it.

In other embodiments, the foregoing indication information may also be capability information of the first NSMF, that is, network slice parameter information that the first NSMF can support, to avoid multiple negotiation. For example, the CSMF expects the first NSMF to create a network slice with a bandwidth of 200M according to the related requirements of the communication service, and asks whether the first NSMF supports the creation of a network slice with a bandwidth of 200M through the first request, and the first NSMF only supports the creation of 100M bandwidth. The network slice is performed. Therefore, when the first NSMF sends the first response, the information that the first NSMF can support the 100M bandwidth is carried in the first response, so that the CSMF modifies the parameter information in the first request according to the first response. The first network parameter information can be determined for the first NSMF, and the number of consultations is reduced.

In a possible implementation, before determining the first network slice parameter, the CSMF may first obtain the network slice parameter information supported by the first NSMF, and the CSMF may be based on the network slice parameter information supported by the first NSMF, or according to the first NSMF. The first network slice parameter information is determined by the supported network slice parameter information and related requirements of the communication service. Through the foregoing method, the first network slice parameter information determined by the CSMF for the first NSMF can be used by the first NSMF to avoid determining the network slice parameter information that the first NSMF is unavailable for the first NSMF.

If the CSMF determines, according to the network slice parameter information that the first NSMF can support, that the first NSMF can create a network slice that meets the communication service related requirements, or modify the parameters of the existing network slice to meet the communication service related requirements, then the CSMF determines The first network slice parameter may be determined according to a communication service related requirement, or may be determined according to network slice parameter information that the first NSMF can support. For example, CSMF determines that a network slice with a bandwidth of 100M needs to be created according to the related requirements of the communication service, and the first NSMF can support the creation of a network slice of 200M bandwidth; obviously, the first NSMF has the ability to create a network slice that satisfies the communication service requirement, then The CSMF can determine that the bandwidth of the network slice to be created by the first NSMF is 100M. Of course, it can also determine that the bandwidth of the network slice to be created is 150M, 200M, etc., which can meet the requirements of the communication server and the capability of exceeding the first NSMF. .

If the CSMF determines that the first NSMF cannot create a network slice that meets the communication service related requirements according to the network slice parameter information that the first NSMF can support, or if the parameters of the existing network slice cannot be modified to meet the communication service related requirements, the CSMF may The first network slice parameter information is determined according to the network slice parameter information that the first NSMF can support, or the first network slice parameter information may be determined to be determined for the first NSMF. For example, the CSMF determines that a network slice with a bandwidth of 100M needs to be created according to the related requirements of the communication service, and the first NSMF only supports the creation of a network slice of 50M bandwidth. In this case, the CSMF can determine the first NSMF according to the capability of the first NSMF. The created network slice has a bandwidth of 50M, or CSMF can also give up the first NSMF to create a network slice.

In addition, the CSMF can also obtain network slice parameter information that each NSMF connected to the CSMF can support. After converting the relevant requirements of the communication service into the parameter information of the network slice, the CSMF selects an NSMF capable of meeting the communication service related requirements to manage the network slice according to the capability of each NSMF, or may select multiple NSMFs to jointly perform. Management to meet the needs of communication services. For example, the CSMF determines that a network slice with a bandwidth of 100M needs to be created according to the related requirements of the communication service, and the NSMF connected to the CSMF does not have the capability of creating a 100M bandwidth network slice, and the CSMF can determine that the first NSMF creates a network slice of 50M bandwidth. And determine the second NSMF to create a 50M bandwidth network slice.

Further, the foregoing CSMF obtains network slice parameter information that can be supported by the first NSMF, and can be implemented by:

In a first method, the CSMF sends a second request to the first NSMF, where the second request is used to request to obtain network slice parameter information that the first NSMF can support; the first NSMF sends a second response to the CSMF, where the second response includes the first Network slice parameter information that NSMF can support.

Optionally, the CSMF may send a second request to the first NSMF when the network slice needs to be created or the parameters of the existing network slice need to be modified according to the related requirements of the communication service, so that the CSMF can be supported according to the first NSMF. The network slice parameter information determines the first network slice information.

Manner 2: The first NSMF may actively report the network slice parameter information that the first NSMF can support to the CSMF.

Optionally, the first NSMF may report the supported network slice parameter information to the CSMF according to the preset period; or the first NSMF may report the supported network slice parameter information to the CSMF when the capability changes. After receiving the capability of reporting the first NSMF, the CSMF may save the network slice parameter information that it can support, so that the CSMF determines that a network slice needs to be created or needs to modify the existing network slice according to the relevant requirements of the communication service. The first network slice parameter information may be determined according to the stored first NSMF supported network slice parameter information. For example, the method can be applied to the case where the CSMF and the first NSMF belong to the same carrier.

For a clear understanding of the network slice management method provided by the embodiment of the present application, the following describes the specific embodiments.

Embodiment 1.

When a network slice needs to be created, CSMF and NSMF manage the network slice according to the process shown in Figure 4, including the following steps:

Step 401: The CSMF sends a query request to the first NSMF, that is, the second request in the foregoing embodiment is used to request to acquire network slice parameter information that the first NSMF can support.

Further, the CSMF may send a query request to multiple NSMFs to query network slice parameter information that each NSMF can support.

Step 402: The first NSMF returns a query response to the CSMF, that is, the second response in the foregoing embodiment, where the response includes network slice parameter information that the NSMF can support.

For example, the response may include information such as the type of the network slice supported by the first NSMF, the SLA, the network KPI, and the like.

Step 403: The CSMF determines, according to the related requirements of the communication service, and the network slice parameter information that the NSMF can support, to determine that the first NSMF can support the network slice parameter information that needs to be created.

In some embodiments, if the first NSMF has the ability to create a network slice that meets the communication service related requirements, the CSMF may request that the network slice be created by the first NSMF. In some embodiments, if multiple NSMFs cannot individually support the various requirements of the network slice to be created, the CSMF may determine that each of the two or more NSMFs creates a network slice so that the created plurality of network slices meet together. The related requirements of the communication service, and the parameter information of the network slice created by each NSMF is sent to an NSMF.

Step 404: The CSMF sends the network slice parameter information that needs to be created to the first NSMF.

Step 405: The first NSMF creates a network slice according to the network slice parameter information sent by the CSMF.

Example 2

When a network slice needs to be created, CSMF and NSMF manage the network slice according to the process shown in Figure 5, which includes the following steps:

Step 501: The CSMF determines that a new network slice needs to be created according to the related requirements of the communication service, and determines network slice parameter information that needs to be created.

Step 502: The CSMF sends a negotiation request to the first NSMF, that is, the first request in the foregoing embodiment, where the negotiation request includes the network slice parameter information determined by the CSMF, to query whether the first NSMF can support the parameter of the network slice to be created. .

Step 503: The first NSMF returns a negotiation response to the CSMF, where the negotiation response includes indication information about whether the first NSMF can support parameters of the network slice to be created.

If the negotiation response indicates that the first NSMF cannot support the parameter of the network slice to be created, the CSMF may modify the network slice parameter information included in the negotiation request, and repeatedly perform the foregoing steps 502 and 503 until the negotiation response representation returned by the first NSMF The first NSMF is capable of supporting parameters of the network slice included in the negotiation request. Of course, when the first NSMF does not support the parameters of the network slice to be created, the CSMF may not modify the network slice parameter information to negotiate with it, but negotiate with other NSMFs or give up the task.

In addition, CSMF can perform one or more steps 502 and 503 with other NSMFs.

Step 504: The CSMF updates the network slice parameter information.

For example, if the first NSMF can support the network slice parameter to be created determined by the CSMF in step 501, the CSMF may determine that the network slice is created by the first NSMF, and the parameter of the network slice created by the first NSMF is determined in step 501. The parameters of the network slice to be created.

For another example, the CSMF sends a negotiation request to multiple NSMFs, but none of the multiple NSMFs can support the network slice parameter to be created determined by the CSMF in step 501, and the CSMF can be based on a negotiation process with multiple NSMFs (ie, the above Step 502 and step 503), determining that network slices are created by the first NSMF and other NSMFs to meet communication service requirements, and determining network slice parameter information created by each NSMF, respectively.

Step 505: The CSMF sends the determined network slice parameter information that needs to be created by the first NSMF to the first NSMF.

Step 506: The first NSMF creates a network slice according to the network slice parameter information sent by the CSMF.

Embodiment 3

The network environment can be changed at any time. In order to meet the related requirements of the communication service, the parameters of the established network slice can be modified. The CSMF and the NSMF manage the network slice according to the process shown in Figure 6, which includes the following steps. :

Step 601: The CSMF acquires performance parameters of the communication service that can be provided by the network slice managed by the first NSMF.

The CSMF obtains performance parameters of the network slice managed by the first NSMF, and determines performance parameters of the communication service that the first NSMF managed network slice can provide according to the performance parameters.

In order to ensure the related requirements of the communication service, the preset value range of the performance parameter of the communication may be set. When the value of the performance parameter is in the preset range, it indicates that the currently provided communication service can meet the communication service requirement. If the scope is set, it indicates that the currently provided communication service cannot meet the communication service requirements and needs to be adjusted.

Step 602: When the value of the performance parameter of the communication service that can be provided by the network slice managed by the first NSMF exceeds a preset range, the CSMF determines the network slice parameter information that needs to be modified according to the related requirement of the communication service.

Step 603: The CSMF sends a negotiation request to the first NSMF, where the negotiation request includes the network slice parameter information to be modified determined by the CSMF, to query whether the first NSMF can support modification of the parameter letters.

Step 604: The first NSMF returns a negotiation response to the CSMF, where the negotiation response includes indication information about whether the first NSMF can support parameters of the network slice to be modified.

If the negotiation response indicates that the first NSMF cannot support the network slice parameter to be modified, the CSMF may modify the network slice parameter information included in the negotiation request, and repeatedly perform the above steps 603 and 604 until the negotiation response representation returned by the first NSMF The first NSMF is capable of supporting parameter information included in the negotiation request.

Step 605: The CSMF updates parameter information of the network slice.

For example, if the CSMF performs multiple negotiation with the first NSMF, that is, the foregoing steps 603 and 604 are performed multiple times, the CSMF may determine the network slice parameter included in the last negotiation request as the network to be modified by the first NSMF. Slice parameters.

Step 606: The CSMF sends the determined network slice parameter information that needs to be modified by the first NSMF to the first NSMF.

Step 607: The first NSMF modifies the network slice parameter according to the network slice parameter information sent by the CSMF.

Step 701: The CSMF receives the network slice parameter adjustment notification sent by the second NSMF.

Since the network environment changes, the second NSMF cannot support the original network slice related requirement, and the second NSMF may send an adjustment notification to the CSMF that manages the second NSMF, where the notification includes the parameters of the network slice managed by the second NSMF. The adjustment information is such that CSMF can understand in time that the network slice managed by the second NSMF cannot meet the requirements of the communication service.

Step 702: The CSMF determines parameter modification information of the network slice managed by the first NSMF according to the parameter adjustment information included in the adjustment notification and the related requirement of the communication service.

Since the communication service that the second NSMF can provide is reduced, in order to meet the related requirements of the communication service, the CSMF hopes to modify the parameters of the network slice managed by the first NSMF to realize that the communication service provided by the total network slice can satisfy the communication. Service related needs.

Step 703: The CSMF sends a negotiation request to the first NSMF, where the negotiation request includes parameter modification information determined by the CSMF to query whether the first NSMF can support modification of the parameter letters.

Step 704: The first NSMF returns a negotiation response to the CSMF, where the negotiation response includes whether the first NSMF can support the modification of the parameter information.

If the negotiation response indicates that the first NSMF cannot support the network slice parameter modification, the CSMF may modify the network slice parameter information included in the negotiation request, and repeatedly perform the foregoing steps 703 and 704 until the negotiation response returned by the first NSMF indicates the first The NSMF can support the parameter information included in the negotiation request.

Step 705: The CSMF updates parameter information of the network slice.

For example, if the CSMF performs multiple negotiation with the first NSMF, that is, the foregoing steps 703 and 704 are performed multiple times, the CSMF may determine the network slice parameter included in the last negotiation request as the network to be modified by the first NSMF. Slice parameters.

Step 706: The CSMF sends the determined network slice parameter information that needs to be modified by the first NSMF to the first NSMF.
