  • Network slicing is a logically isolated network created on physical or virtual infrastructure to support specific network capabilities and network characteristics. It can include a complete end-to-end entire network including RAN, TN, CN and application servers. Some network functions can also be shared among multiple network slices, which is a key technology to meet the network differentiation requirements of 5G mobile communication technology proposed by the 3rd generation partnership project (3GPP). Usually, the network characteristics of different network slices are different, and network slices are required to be isolated from each other and not affect each other. For example, network slicing for augmented reality (AR) or virtual reality (VR) services requires large bandwidth and low latency; network slicing for Internet of Things (IoT) services requires supporting massive terminal access. However, the bandwidth is small and the latency requirements are low. Network slicing can also be any combination of user equipment, access network, transmission network, core network and application server.

下面对本申请实施例可能涉及的几个概念进行定义：Several concepts that may be involved in the embodiments of this application are defined below:
网络切片是创建在物理或者虚拟的基础设施上的，用于支持特定网络能力与网络特性的逻辑隔离的网络，可以包括RAN、TN、CN和应用服务器在内的完整的端到端的整个网络，部分网络功能也可以在多个网络切片中共享，是满足第三代合作伙伴计划(3rd generation partnership project，3GPP)提出的5G移动通信技术关于网络差异化需求的关键技术。通常，不同网络切片的网络特征并不相同，且要求网络切片之间相互隔离，互不影响。如增强现实(augmented reality，AR)或虚拟实现(virtual reality，VR)业务的网络切片要求大带宽、低时延；物联网(internet of things，IoT)业务的网络切片要求支持海量终端接入，但带宽小，对时延要求低。网络切片也可以是用户设备、接入网、传输网、核心网和应用服务器的任意组合。Network slicing is a logically isolated network created on physical or virtual infrastructure to support specific network capabilities and network characteristics. It can include a complete end-to-end entire network including RAN, TN, CN and application servers. Some network functions can also be shared among multiple network slices, which is a key technology to meet the network differentiation requirements of 5G mobile communication technology proposed by the 3rd generation partnership project (3GPP). Usually, the network characteristics of different network slices are different, and network slices are required to be isolated from each other and not affect each other. For example, network slicing for augmented reality (AR) or virtual reality (VR) services requires large bandwidth and low latency; network slicing for Internet of Things (IoT) services requires supporting massive terminal access. However, the bandwidth is small and the latency requirements are low. Network slicing can also be any combination of user equipment, access network, transmission network, core network and application server.
网络切片实例是一个真实运行的逻辑网络，能满足一定网络特性或服务需求。网络切片 实例使得运营商能够在一个物理网络之上构建多个专用的、虚拟的、隔离的、按需定制的逻辑网络，满足不同行业客户对网络能力的不同要求(如时延、带宽、连接数等)。一个网络切片实例可能提供一种或多种网络服务。网络切片实例可以由网络切片管理***创建，一个网络切片管理***可能创建多个网络切片实例并同时对它们进行管理。示例性地，每个网络切片实例可以包含以下至少一个网络切片子网实例：核心网网络切片子网实例、传输网网络切片子网实例和无线接入网网络切片子网实例。网络切片实例可基于网络切片模板(network slice template，NST)创建。A network slicing instance is a real-running logical network that can meet certain network characteristics or service requirements. network slicing Instances enable operators to build multiple dedicated, virtual, isolated, and customized logical networks on a physical network to meet the different requirements of customers in different industries for network capabilities (such as latency, bandwidth, number of connections, etc. ). A network slice instance may provide one or more network services. Network slicing instances can be created by a network slicing management system. A network slicing management system may create multiple network slicing instances and manage them simultaneously. Exemplarily, each network slicing instance may include at least one of the following network slicing subnet instances: a core network slicing subnet instance, a transmission network slicing subnet instance, and a radio access network network slicing subnet instance. A network slice instance can be created based on a network slice template (NST).
一个完整的网络切片实例是能够提供完整的端到端的网络服务的，而组成网络切片实例的可以是网络切片子网实例和/或网络功能。网络切片子网实例是指代表了网络切片子网实例中支持网络切片实例的一组网络功能和相关资源(例如计算、存储和网络资源)。网络切片子网实例可基于网络切片子网模板(network slice subnet template，NSST)创建。A complete network slicing instance can provide complete end-to-end network services, and the network slicing instance can be composed of network slicing subnet instances and/or network functions. A network slicing subnet instance refers to a set of network functions and related resources (such as computing, storage, and network resources) that support the network slicing instance in the network slicing subnet instance. A network slice subnet instance can be created based on a network slice subnet template (NSST).
网络切片需求信息包括服务等级协议(service level agreement，SLA)。SLA是服务提供商和客户之间的合同(或合同的一部分)，旨在建立对服务、优先级、责任等的共同理解。5G移动通信技术作为新一轮通信技术代际跃迁，更多聚焦于为垂直行业赋能。根据垂直行业需求，通信网络的网络性能指标包括以下一个或多个网络性能指标：用户速率、端到端时延、包可靠性(reliability)、吞吐量(throughput)、覆盖(coverage)、能量(energy)、定位精度、时钟同步。5G通过网络切片技术从一张物理网络中切出多个“切片”，以业务的网络切片需求信息为中心，为toB(to Business)业务提供定制化、差异化和确定性的网络服务能力。Network slicing requirement information includes service level agreement (SLA). An SLA is a contract (or part of a contract) between a service provider and a customer that establishes a shared understanding of services, priorities, responsibilities, etc. As a new generational leap in communication technology, 5G mobile communication technology focuses more on empowering vertical industries. According to the needs of vertical industries, network performance indicators of communication networks include one or more of the following network performance indicators: user rate, end-to-end delay, packet reliability, throughput, coverage, energy ( energy), positioning accuracy, and clock synchronization. 5G uses network slicing technology to cut multiple "slices" from a physical network, focusing on business network slicing requirement information to provide customized, differentiated and deterministic network service capabilities for toB (to Business) services.
网络切片需求是对端到端网络切片实例的要求，它需要被网络切片管理设备分解并交由各网络切片子网管理设备负责满足。其中，分解网络切片需求是指基于网络切片需求生成多个目标网络切片子网需求。以端到端时延为例，端到端时延是各网络切片子网实例的时延之和，网络切片管理设备根据网络切片需求得到网络切片实例的时延需求为100ms，那么网络切片管理设备根据各域(包括核心网、无线接入网和传输网)能力可能会将时延生成各网络切片子网实例的时延需求：70ms、15ms、15ms，并分别发送给各网络切片子网管理设备。Network slicing requirements are requirements for end-to-end network slicing instances, which need to be decomposed by the network slicing management device and handed over to each network slicing subnet management device to satisfy. Among them, decomposing network slicing requirements means generating multiple target network slicing subnet requirements based on network slicing requirements. Take the end-to-end delay as an example. The end-to-end delay is the sum of the delays of each network slicing subnet instance. The network slicing management device obtains the delay requirement of the network slicing instance as 100ms based on the network slicing requirements. Then the network slicing management Depending on the capabilities of each domain (including core network, wireless access network, and transmission network), the device may generate the delay requirements of each network slice subnet instance: 70ms, 15ms, and 15ms, and send them to each network slice subnet respectively. Manage devices.
当现有网络切片实例无法满足某一业务的网络切片需求时，就需要创建新的网络切片实例承载该业务。创建网络切片实例的首要任务就是提炼出网络切片需求信息，并进一步生成目标网络切片子网需求信息。如图2所示，为本申请实施例提供的一种网络切片实例创建示意图。在图2中，网络切片实例客户(如工厂，贵宾(very important person，VIP)用户)对业务场景需求按照全球移动通信***协会(global system for mobile communications association，GSMA)制定的通用切片模板(generic slice template，GST)进行整理。然后，运营商将其转译成3GPP定义的网络切片实例的网络切片需求信息(ServiceProfile)并发送给网络切片管理设备(如NSMF网元)。网络切片管理设备得到端到端的网络切片需求信息后，根据各网络切片子网实例(包括核心网、无线接入网和传输网)的能力，根据网络切片需求信息生成目标网络切片子网需求信息(SliceProfile)，并传递给网络切片子网管理设备(NSSMF网元)。各网络切片子网管理设备得到网络切片管理设备发送的目标网络切片子网需求信息后，根据该目标网络切片子网需求信息执行网络切片子网实例创建流程。When an existing network slicing instance cannot meet the network slicing requirements of a certain service, a new network slicing instance needs to be created to carry the service. The first task of creating a network slicing instance is to extract the network slicing requirement information and further generate the target network slicing subnet requirement information. As shown in Figure 2, it is a schematic diagram of creating a network slicing instance provided by the embodiment of this application. In Figure 2, the business scenario requirements of network slicing instance customers (such as factories, VIP users) are in accordance with the general slicing template (generic) developed by the Global System for Mobile Communications Association (GSMA) slice template, GST) for sorting. Then, the operator translates it into the network slicing requirement information (ServiceProfile) of the network slicing instance defined by 3GPP and sends it to the network slicing management device (such as NSMF network element). After obtaining the end-to-end network slicing demand information, the network slicing management device generates target network slicing subnet demand information based on the capabilities of each network slicing subnet instance (including the core network, wireless access network, and transmission network). (SliceProfile) and passed to the network slice subnet management device (NSSMF network element). After each network slice subnet management device obtains the target network slice subnet demand information sent by the network slice management device, it executes the network slice subnet instance creation process according to the target network slice subnet demand information.
其中，上述ServiceProfile包括SLA、业务特征信息和一些公共属性等。Among them, the above-mentioned ServiceProfile includes SLA, business characteristic information and some public attributes.
上述目标网络切片子网需求信息包括网络切片子网实例的网络性能指标、网络切片子网实例对应的业务特征信息和一些公共属性等。The above target network slicing subnet requirement information includes network performance indicators of the network slicing subnet instance, business feature information corresponding to the network slicing subnet instance, and some public attributes.
如图3所示，为本申请实施例提供的一种网络管理方法的流程示意图。示例性地，可以包括以下步骤： As shown in Figure 3, it is a schematic flow chart of a network management method provided by an embodiment of the present application. For example, the following steps may be included:
S301.网络切片管理设备分别向各网络切片子网管理设备(图中示例了2个网络切片子网管理设备：网络切片子网管理设备1和网络切片子网管理设备2)发送能力查询请求。S301. The network slice management device sends capability query requests to each network slice subnet management device (the figure illustrates two network slice subnet management devices: network slice subnet management device 1 and network slice subnet management device 2).
示例性地，该能力查询请求的格式可以是：指标列表<指标名称>。其中，指标列表包括一个或多个网络性能指标的指标名称。其中，指标名称也可以替换为指标标识。示例性地，该指标列表包括：‘delay’、‘reliability’、‘throughput’、‘coverage’，‘energy’等。For example, the format of the capability query request may be: indicator list <indicator name>. The indicator list includes the indicator names of one or more network performance indicators. Among them, the indicator name can also be replaced by the indicator ID. For example, the indicator list includes: 'delay', 'reliability', 'throughput', 'coverage', 'energy', etc.
S302.网络切片子网管理设备1、网络切片子网管理设备2收到能力查询请求后，分别获取相应的网络切片子网实例的静态能力信息。S302. After receiving the capability query request, the network slice subnet management device 1 and the network slice subnet management device 2 respectively obtain the static capability information of the corresponding network slice subnet instance.
示例性地，网络切片子网管理设备1、网络切片子网管理设备2分别评估相应的各个网络性能指标分别能达到的最优值。即该静态能力信息指示相应的网络切片子网实例的一个或多个网络性能指标分别能达到的最优值。例如，网络切片子网实例的时延最低能达到50ms，可靠性最高能达到99.999％，吞吐率最大能达到100Mbps。For example, the network slice subnet management device 1 and the network slice subnet management device 2 respectively evaluate the optimal values that the corresponding network performance indicators can respectively achieve. That is, the static capability information indicates the optimal value that one or more network performance indicators of the corresponding network slice subnet instance can respectively achieve. For example, the latency of a network slicing subnet instance can reach a minimum of 50ms, the reliability can reach a maximum of 99.999%, and the throughput can reach a maximum of 100Mbps.
S303.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送能力查询反馈。S303. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send capability query feedback to the network slice management device.
示例性地，该能力反馈的格式可以是：能力信息列表<指标名称，能力值>。其中，指标名称与步骤S301的能力查询请求中的指标名称保持一致；能力值指示相应的网络切片子网实例的静态能力信息，例如该能力值指示相应的网络切片子网实例在各项指标上分别能达到的最优值。For example, the format of the capability feedback may be: capability information list <indicator name, capability value>. Among them, the indicator name is consistent with the indicator name in the capability query request in step S301; the capability value indicates the static capability information of the corresponding network slice subnet instance. For example, the capability value indicates that the corresponding network slice subnet instance is on each indicator. The optimal value that can be achieved respectively.
例如，某个网络切片子网管理设备反馈的能力信息列表可以包括[<‘delay’，50ms>，<‘reliability’，99.999％>，<‘throughput’，100Mbps>]，指示相应的网络切片子网实例的时延最低能达到50ms，可靠性最高能达到99.999％，吞吐率最大能达到100Mbps。For example, the capability information list fed back by a certain network slice subnet management device may include [<'delay', 50ms>, <'reliability', 99.999%>, <'throughput', 100Mbps>], indicating the corresponding network slice subnet. The latency of network instances can reach a minimum of 50ms, the reliability can reach a maximum of 99.999%, and the throughput rate can reach a maximum of 100Mbps.
S304.网络切片管理设备根据网络切片需求信息以及静态能力信息，生成目标网络切片子网需求信息。S304. The network slicing management device generates target network slicing subnet demand information based on the network slicing demand information and static capability information.
示例性地，根据网络切片需求信息中的一个或多个网络性能指标、各网络切片子网实例中每个网络性能指标之间的关系以及静态能力信息，生成目标网络切片子网需求信息。Exemplarily, the target network slice subnet requirement information is generated according to one or more network performance indicators in the network slice requirement information, the relationship between each network performance indicator in each network slice subnet instance, and the static capability information.
其中，各网络切片子网实例中每个网络性能指标之间的关系包括：网络切片实例的时延等于各网络切片子网实例的时延之和，网络切片实例的可靠性等于各网络切片子网实例的可靠性的乘积，网络切片实例的吞吐率等于各网络切片子网实例的吞吐率的最小值，等等。Among them, the relationship between each network performance indicator in each network slice subnet instance includes: the latency of the network slice instance is equal to the sum of the latency of each network slice subnet instance, and the reliability of the network slice instance is equal to the sum of the latency of each network slice subnet instance. The product of the reliability of the network instance, the throughput rate of the network slice instance is equal to the minimum throughput rate of each network slice subnet instance, and so on.
生成目标网络切片子网需求信息的过程主要依靠多次试错。以时延和可靠性指标为例，若某个网络切片子网实例的时延指标未达成，则在下一次生成目标网络切片子网需求信息时提高时延阈值，同时可以增大可靠性的阈值。The process of generating target network slice subnet requirement information mainly relies on multiple trials and errors. Taking the delay and reliability indicators as an example, if the delay indicator of a certain network slice subnet instance is not reached, the delay threshold will be increased the next time the target network slice subnet demand information is generated, and the reliability threshold can also be increased. .
S305.网络切片管理设备分别向网络切片子网管理设备1、网络切片子网管理设备2发送网络切片子网实例创建请求。S305. The network slice management device sends a network slice subnet instance creation request to the network slice subnet management device 1 and the network slice subnet management device 2 respectively.
其中，发送给网络切片子网管理设备1的网络切片子网实例创建请求包括第一目标网络切片子网需求信息，该第一目标网络切片子网需求信息用于创建网络切片子网实例1。发送给网络切片子网管理设备2的第二目标网络切片子网需求信息用于创建网络切片子网实例2。目标网络切片子网需求信息可以是上述SliceProfile。The network slice subnet instance creation request sent to the network slice subnet management device 1 includes first target network slice subnet requirement information, and the first target network slice subnet requirement information is used to create the network slice subnet instance 1 . The second target network slice subnet requirement information sent to the network slice subnet management device 2 is used to create the network slice subnet instance 2 . The target network slice subnet requirement information may be the above-mentioned SliceProfile.
S306.网络切片子网管理设备1、网络切片子网管理设备2分别根据网络切片子网实例创建请求，执行网络切片子网实例创建流程。S306. The network slicing subnet management device 1 and the network slicing subnet management device 2 respectively execute the network slicing subnet instance creation process according to the network slicing subnet instance creation request.
S307.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送网络切片子网实例创建反馈。S307. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send network slice subnet instance creation feedback to the network slice management device.
其中，该网络切片子网实例创建反馈包括指示信息。该指示信息可以是一个标识(flag) 信元。其中flag信元指示网络切片子网实例是否创建成功，取值为“成功(true)”或“失败(false)”。The network slice subnet instance creation feedback includes instruction information. The indication information may be a flag Cell. The flag cell indicates whether the network slice subnet instance is successfully created, and its value is "success (true)" or "failure (false)".
在该实施例中，网络切片子网管理设备在能力查询反馈中携带网络切片管理设备指定的各项网络性能指标分别能达到的最优值。但是这些静态能力信息只能说明网络切片子网实例在各项指标上的最优值。而这些指标间存在关联性(例如时延增大会影响到可靠性和吞吐率)，其关联关系由网络切片子网实例的实际情况决定，各个指标上的最优值不能代表整个网络切片子网实例的实际值(例如时延达到50ms的同时可靠性只能到99.9％)。如果网络切片管理设备按照各网络切片子网管理设备上报的静态能力信息和网络切片需求信息生成目标网络切片子网需求信息，这个静态能力信息不能反映各网络切片子网实例在所有网络性能指标上取值的取舍(例如要想实现低时延，吞吐率指标要求就得放低)，导致各网络切片子网实例很可能达不成各自的目标网络切片子网需求，这就需要网络切片管理设备多次执行生成目标网络切片子网需求信息的过程。另一方面，网络切片管理设备生成了目标网络切片子网需求信息之后，将目标网络切片子网需求信息发送给相应的网络切片子网管理设备，各网络切片子网管理设备直接在物理网络上创建网络切片子网实例，由于生成的目标网络切片子网需求信息的可靠性低，各网络切片子网实例会进行多次网络切片子网实例创建，这大大增加了对在同一物理网络上同时运行的其他业务造成的影响以及网络出问题的概率和网络回退的代价。In this embodiment, the network slice subnet management device carries in the capability query feedback the optimal values that can be achieved for each network performance indicator specified by the network slice management device. However, this static capability information can only illustrate the optimal values of various indicators for network slicing subnet instances. There is a correlation between these indicators (for example, an increase in latency will affect reliability and throughput). The correlation is determined by the actual situation of the network slicing subnet instance. The optimal value of each indicator cannot represent the entire network slicing subnet. The actual value of the instance (for example, when the delay reaches 50ms, the reliability can only reach 99.9%). If the network slice management device generates target network slice subnet requirement information based on the static capability information and network slice requirement information reported by each network slice subnet management device, this static capability information cannot reflect all network performance indicators of each network slice subnet instance. Value trade-offs (for example, to achieve low latency, the throughput index requirement must be lowered), resulting in each network slicing subnet instance being likely to fail to meet its own target network slicing subnet requirements, which requires network slicing management equipment The process of generating target network slice subnet requirement information is performed multiple times. On the other hand, after the network slice management device generates the target network slice subnet demand information, it sends the target network slice subnet demand information to the corresponding network slice subnet management device. Each network slice subnet management device is directly on the physical network. Create a network slicing subnet instance. Due to the low reliability of the generated target network slicing subnet requirement information, each network slicing subnet instance will be created multiple times, which greatly increases the need for simultaneous network slicing subnet instances on the same physical network. The impact caused by other running services, the probability of network problems and the cost of network rollback.
有鉴于此，本申请实施例还提供一种网络管理方案，基于网络切片需求信息和预估能力信息集生成目标网络切片子网需求信息，指示网络切片子网管理设备基于目标网络切片子网需求信息创建目标网络切片子网实例，从而提高了网络切片子网实例创建的成功率。In view of this, embodiments of the present application also provide a network management solution that generates target network slice subnet demand information based on network slice demand information and estimated capability information sets, and instructs the network slice subnet management device to based on the target network slice subnet demand. The information creates a target network slice subnet instance, thereby improving the success rate of network slice subnet instance creation.

This method is used by a network slicing management device to manage a network slicing instance. The network slicing instance has N network slicing subnet instances to be created, N≥2. In this embodiment, N=2. Exemplarily, the method may include the following steps:
S401.网络切片管理设备根据网络切片需求信息获取预估能力信息集。如图2所示，网络切片管理设备从运营商接收转译后的网络切片需求信息(如上述ServiceProfile)。网络切片需求信息是指对端到端网络切片实例的要求，包括用户速率、端到端时延、包可靠性、吞吐量、覆盖、能量、定位精度、时钟同步等一个或多个网络性能指标。S401. The network slicing management device obtains the estimated capability information set according to the network slicing requirement information. As shown in Figure 2, the network slicing management device receives translated network slicing requirement information (such as the above-mentioned ServiceProfile) from the operator. Network slicing requirement information refers to the requirements for end-to-end network slicing instances, including one or more network performance indicators such as user rate, end-to-end delay, packet reliability, throughput, coverage, energy, positioning accuracy, clock synchronization, etc. .
网络切片管理设备解析出网络切片需求信息后，需要分解该网络切片需求。为了提高分解的成功率，网络切片管理设备在分解网络切片需求之前，根据该网络切片需求信息获取预估能力信息集。After the network slicing management device parses the network slicing requirement information, it needs to decompose the network slicing requirement. In order to improve the success rate of decomposition, before decomposing network slicing requirements, the network slice management device obtains an estimated capability information set based on the network slicing requirement information.
其中，预估能力信息集包含至少两条分别对应N个网络切片子网实例中不同网络切片子网实例的预估能力信息。示例性地，可以是一个待创建的网络切片子网实例对应一条预估能力信息。The estimated capability information set includes at least two pieces of estimated capability information respectively corresponding to different network slice subnet instances among the N network slice subnet instances. For example, a network slice subnet instance to be created may correspond to a piece of estimated capability information.
网络切片管理设备可以从至少两个网络切片子网管理设备分别获取N个网络切片子网实例中的一个网络切片子网实例的预估能力信息，得到至少两条预估能力信息。如图4所示，假设N＝2，网络切片管理设备可以从网络切片子网管理设备1获取一个网络切片子网实例的预估能力信息，以及可以从网络切片子网管理设备2获取另一个网络切片子网实例的预估能力信息。N＝2仅为示例，本申请对网络切片子网实例的数量不作限制。The network slice management device may respectively obtain the estimated capability information of one network slice subnet instance among the N network slice subnet instances from at least two network slice subnet management devices, and obtain at least two pieces of estimated capability information. As shown in Figure 4, assuming N=2, the network slice management device can obtain the estimated capability information of one network slice subnet instance from the network slice subnet management device 1, and can obtain another network slice subnet instance from the network slice subnet management device 2. Estimated capability information for network slice subnet instances. N=2 is only an example, and this application does not limit the number of network slicing subnet instances.
预估能力信息是指对还未创建的网络切片子网实例的能力的预先评估。Estimated capability information refers to a pre-evaluation of the capabilities of network slice subnet instances that have not yet been created.
其中每一条预估能力信息包含相应的网络切片子网实例的静态能力信息和动态能力信息。Each piece of estimated capability information includes static capability information and dynamic capability information of the corresponding network slice subnet instance.
静态能力信息指示相应的网络切片子网实例的一个或多个网络性能指标分别能达到的最优值。例如，某个网络切片子网实例的时延最低能达到50ms，可靠性最高能达到99.999％，吞吐率最大能达到100Mbps。 The static capability information indicates the optimal value that one or more network performance indicators of the corresponding network slice subnet instance can respectively achieve. For example, the latency of a network slicing subnet instance can reach a minimum of 50ms, the reliability can reach a maximum of 99.999%, and the throughput can reach a maximum of 100Mbps.
动态能力信息指示相应的网络切片子网实例的一个或多个网络性能指标分别能达到的实际值。各个网络性能指标之间存在关联性(例如时延增大会影响到可靠性和吞吐率)，其关联关系由网络切片子网实例的实际情况决定；以及网络切片子网实例能否达成网络切片子网需求，是由网络切片子网实例的实际情况决定的。通过动态能力信息可以指示相应的网络切片子网实例的一个或多个网络性能指标分别能达到的实际值。The dynamic capability information indicates the actual values that one or more network performance indicators of the corresponding network slice subnet instance can respectively achieve. There is a correlation between various network performance indicators (for example, an increase in latency will affect reliability and throughput), and the correlation is determined by the actual situation of the network slicing subnet instance; and whether the network slicing subnet instance can achieve the network slicing subnet instance. Network requirements are determined by the actual situation of the network slicing subnet instance. The dynamic capability information can indicate the actual values that one or more network performance indicators of the corresponding network slice subnet instance can respectively achieve.
S402.网络切片管理设备基于网络切片需求信息和预估能力信息集生成目标网络切片子网需求信息。S402. The network slice management device generates target network slice subnet demand information based on the network slice demand information and the estimated capability information set.
网络切片管理设备获取到预估能力信息集后，需要分解该网络切片需求，生成目标网络切片子网需求信息。具体地，网络切片管理设备根据网络切片需要信息包括的一个或多个网络性能指标、各网络切片子网实例中每个网络性能指标之间的关系以及各个网络切片子网管理设备发送的预估能力信息，生成目标网络切片子网需求信息。该目标网络切片子网需求信息可以是上述SliceProfile。其中，该目标网络切片子网需求信息用于创建N个网络切片子网实例中的目标网络切片子网实例。目标网络切片子网需求信息包括要求目标网络切片子网实例应达到的一个或多个网络性能指标。After the network slice management device obtains the estimated capability information set, it needs to decompose the network slice requirements and generate the target network slice subnet requirement information. Specifically, the network slice management device determines the relationship between one or more network performance indicators included in the network slice requirement information, the relationship between each network performance indicator in each network slice subnet instance, and the estimate sent by each network slice subnet management device. Capability information is used to generate target network slice subnet requirement information. The target network slice subnet requirement information may be the above-mentioned SliceProfile. Wherein, the target network slicing subnet requirement information is used to create a target network slicing subnet instance among the N network slicing subnet instances. The target network slice subnet requirement information includes one or more network performance indicators that the target network slice subnet instance should achieve.
本实施例中，网络切片管理设备在生成目标网络切片子网需求信息时，不仅考虑了网络切片需求信息和静态能力信息，还考虑了动态能力信息，即考虑了相应的网络切片子网实例的一个或多个网络性能指标分别能达到的最优值和实际值，从而生成的目标网络切片子网需求信息更可靠。In this embodiment, when generating the target network slice subnet requirement information, the network slice management device not only considers the network slice requirement information and static capability information, but also considers the dynamic capability information, that is, it considers the corresponding network slice subnet instance.

如图5所示，为本申请实施例提供的又一种网络管理方法的流程示意图。该方法用于网络切片管理设备对网络切片实例进行管理，该网络切片实例有N个网络切片子网实例待创建，N≥2。在本实施例中，N＝2。示例性地，该方法可以包括以下步骤：As shown in Figure 5, it is a schematic flow chart of yet another network management method provided by an embodiment of the present application. This method is used by a network slicing management device to manage a network slicing instance. The network slicing instance has N network slicing subnet instances to be created, N≥2. In this embodiment, N=2. Exemplarily, the method may include the following steps:
S501.网络切片管理设备向各网络切片子网管理设备(图中示例了2个网络切片子网管理设备：网络切片子网管理设备1和网络切片子网管理设备2)分别发送能力查询请求。S501. The network slice management device sends capability query requests to each network slice subnet management device (the figure illustrates two network slice subnet management devices: network slice subnet management device 1 and network slice subnet management device 2).
相应地，网络切片子网管理设备1和网络切片子网管理设备2分别接收该能力查询请求。Correspondingly, the network slice subnet management device 1 and the network slice subnet management device 2 respectively receive the capability query request.
示例性地，该能力查询请求包括：指标列表<指标名称>。其中，指标列表包括一个或多个网络性能指标的指标名称。指标名称可以是‘delay’、‘reliability’、‘throughput’、‘coverage’，‘energy’等。 For example, the capability query request includes: indicator list <indicator name>. The indicator list includes the indicator names of one or more network performance indicators. Indicator names can be 'delay', 'reliability', 'throughput', 'coverage', 'energy', etc.
与步骤S301不同的是，本实施例中，该能力查询请求还包括关联信息上报指示。Different from step S301, in this embodiment, the capability query request also includes a related information reporting instruction.
在一个实现中，该关联信息上报指示用于指示各网络切片子网管理设备是否在能力查询反馈中携带一个或多个关联信息。其中，每个关联信息用于指示每个网络切片子网实例的两个或多个网络性能指标之间的关联关系。示例性地，该关联信息上报指示可以是1比特，其取值为“1”时，表示“是(true)”(携带关联信息)；取值为“0”时，表示“否(false)”(不携带关联信息)。或者，其取值为“0”时，表示“是”(携带关联信息)；取值为“1”时，表示“否”(不携带关联信息)。In one implementation, the association information reporting indication is used to indicate whether each network slice subnet management device carries one or more association information in the capability query feedback. Each correlation information is used to indicate the correlation between two or more network performance indicators of each network slice subnet instance. For example, the association information reporting indication may be 1 bit. When the value is "1", it means "true" (carrying association information); when the value is "0", it means "no (false)". ” (does not carry associated information). Or, when the value is "0", it means "yes" (carrying related information); when the value is "1", it means "no" (carrying no related information).
在另一个实现中，该关联信息上报指示用于指示各网络切片子网管理设备是否在能力查询反馈中携带一个或多个关联信息以及上报方式。其中，上报方式可以包括以表格方式上报、以公式方式上报、以分段函数方式上报等。假设上报方式包括上述三种方式，则该关联信息上报指示可以是2比特，其取值为“00”时，表示“否(false)”不携带关联信息；取值为“01”时，表示“table”(以表格方式上报关联信息)；取值为“10”时，表示“formula”(以公式方式上报关联信息)；取值为“11”时，表示“segmental function”(以分段函数方式上报关联信息)。上述关于取值及其对应的含义仅为示例，本申请对此不作限制。In another implementation, the association information reporting indication is used to indicate whether each network slice subnet management device carries one or more association information in the capability query feedback and the reporting method. Among them, the reporting methods may include reporting in the form of tables, reporting in the form of formulas, reporting in the form of piecewise functions, etc. Assuming that the reporting methods include the above three methods, the association information reporting indication can be 2 bits. When the value is "00", it means "no (false)" does not carry the association information; when the value is "01", it means "table" (reporting related information in the form of a table); when the value is "10", it means "formula" (reporting the related information in the form of a formula); when the value is "11", it means "segmental function" (in the form of segments Functionally report related information). The above values and their corresponding meanings are only examples, and this application does not limit them.
S502.网络切片子网管理设备1、网络切片子网管理设备2收到能力查询请求后，分别评估相应的网络切片子网实例在各个指标上分别能达到的最优值，并获取网络切片子网实例中多个网络性能指标之间的一个或多个关联关系。S502. After receiving the capability query request, the network slicing subnet management device 1 and the network slicing subnet management device 2 respectively evaluate the optimal values that the corresponding network slicing subnet instance can achieve on each indicator, and obtain the network slicing subnet. One or more correlations between multiple network performance indicators in a network instance.
在本实施例中，预估能力信息包括相应的网络切片子网实例的静态能力信息和动态能力信息。其中，静态能力信息指示所述目标网络切片子网实例的一个或多个网络性能指标分别能达到的最优值。动态能力信息指示相应的网络切片子网实例的多个网络性能指标之间的关联关系，基于多个网络性能指标之间的关联关系，可以得出多个网络性能指标分别能达到的实际值。In this embodiment, the estimated capability information includes static capability information and dynamic capability information of the corresponding network slice subnet instance. The static capability information indicates the optimal value that one or more network performance indicators of the target network slice subnet instance can respectively achieve. The dynamic capability information indicates the correlation between multiple network performance indicators of the corresponding network slice subnet instance. Based on the correlation between the multiple network performance indicators, the actual values that the multiple network performance indicators can achieve can be obtained.
各网络切片子网管理设备收到能力查询请求后，评估各自对应的网络切片子网实例在各个指标上分别能达到的最优值。例如，网络切片子网管理设备1对应的网络切片子网实例中，时延最低能达到50ms；可靠性最高能达到99.999％；吞吐量最高能达到100Mbps。上述最优值没有考虑各指标之间的相互影响。After receiving the capability query request, each network slice subnet management device evaluates the optimal values that its corresponding network slice subnet instance can achieve on each indicator. For example, in the network slicing subnet instance corresponding to network slicing subnet management device 1, the lowest latency can reach 50ms; the highest reliability can reach 99.999%; and the highest throughput can reach 100Mbps. The above optimal values do not consider the interaction between various indicators.
多个网络性能指标之间存在关联性，且该关联关系由网络切片子网实例的实际情况(例如，小区算法开关、基站数量、基站位置、用户面功能(user plane function，UPF)网元位置、核心网网络功能数量等，这些参数是网管可配置的)决定，为多个网络性能指标之间相互影响的定量描述。因此，各网络切片子网管理设备还获取网络切片子网实例中多个网络性能指标之间的一个或多个关联关系。每个关联信息用于指示每个网络切片子网实例中两个或多个网络性能指标之间的关联关系。例如，网络性能指标包括时延、可靠性、吞吐量，则该多个关联关系包括时延与可靠性之间的关联关系、时延、可靠性与吞吐量之间的关联关系，等等。基于该一个或多个关联关系，可以得出多个网络性能指标分别能达到的实际值。There is a correlation between multiple network performance indicators, and the correlation is determined by the actual situation of the network slicing subnet instance (for example, cell algorithm switch, number of base stations, base station location, user plane function (UPF) network element location , the number of core network network functions, etc., these parameters are configurable by the network management) and are a quantitative description of the interaction between multiple network performance indicators. Therefore, each network slice subnet management device also obtains one or more correlations between multiple network performance indicators in the network slice subnet instance. Each correlation information is used to indicate the correlation between two or more network performance indicators in each network slice subnet instance. For example, if network performance indicators include delay, reliability, and throughput, then the multiple correlations include correlations between delay and reliability, correlations between delay, reliability, and throughput, and so on. Based on the one or more correlation relationships, the actual values that can be achieved by multiple network performance indicators can be obtained.
S503.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送能力查询反馈。S503. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send capability query feedback to the network slice management device.
该能力查询反馈包括目标网络切片子网实例的预估能力信息。示例性地，该能力查询反馈包括：能力信息列表<指标名称，能力值>、一个或多个关联关系。网络切片子网管理设备1、网络切片子网管理设备2分别发送的预估能力信息构成一个预估能力信息集。The capability query feedback includes estimated capability information of the target network slice subnet instance. For example, the capability query feedback includes: capability information list <indicator name, capability value>, and one or more associations. The estimated capability information sent by the network slice subnet management device 1 and the network slice subnet management device 2 respectively constitutes an estimated capability information set.
其中，指标名称与步骤S501的能力查询请求中的指标名称保持一致；能力值指示网络切片子网实例在各项指标上分别能达到的最优值。 Among them, the indicator name is consistent with the indicator name in the capability query request in step S501; the capability value indicates the optimal value that the network slice subnet instance can achieve on each indicator.
例如，能力信息列表可以是[<‘delay’，50ms>，<‘reliability’，99.999％>，<‘throughput’，100Mbps>]，指示在各自最优的网络切片子网实例配置下，时延最低能达到50ms，可靠性最高能达到99.999％，吞吐率最大能达到100Mbps。For example, the capability information list can be [<'delay', 50ms>, <'reliability', 99.999%>, <'throughput', 100Mbps>], indicating the delay under the respective optimal network slice subnet instance configuration. The lowest can reach 50ms, the highest reliability can reach 99.999%, and the highest throughput can reach 100Mbps.
与步骤S303不同的是，该能力查询反馈还包括上述一个或多个关联关系。该关联关系的上报方式为步骤S501中关联信息上报指示中所指示的上报方式。Different from step S303, the capability query feedback also includes one or more of the above-mentioned associations. The reporting method of the association relationship is the reporting method indicated in the association information reporting instruction in step S501.
在一个实现中，上报方式为表格方式上报。假设网络切片需求信息包括以下3个网络性能指标：时延、可靠性、吞吐量，示例性地，上述3个网络性能指标之间的关联关系如下表1所示：In one implementation, the reporting method is tabular reporting. Assume that the network slicing requirement information includes the following three network performance indicators: latency, reliability, and throughput. For example, the correlation between the above three network performance indicators is as shown in Table 1 below:
表1
Table 1
表1记录了每种网络切片子网实例实际情况下3个网络性能指标的实际取值。Table 1 records the actual values of the three network performance indicators for each network slicing subnet instance.
由表1可知，时延为200ms时，可靠性为99.9999％，以及吞吐量为100Mbps；时延为100ms时，可靠性为99.999％，以及吞吐量为80Mbps；时延为50ms时，可靠性为99.9％，以及吞吐量为50Mbps。可见，时延、可靠性、吞吐量之间相互影响。It can be seen from Table 1 that when the delay is 200ms, the reliability is 99.9999%, and the throughput is 100Mbps; when the delay is 100ms, the reliability is 99.999%, and the throughput is 80Mbps; when the delay is 50ms, the reliability is 99.9%, and a throughput of 50Mbps. It can be seen that delay, reliability, and throughput affect each other.
在另一个实现中，上报方式为公式上报。该公式为对每种网络切片子网实例实际情况下2个网络性能指标的实际取值进行拟合，用数学公式表达2个网络性能指标之间的关联关系。例如，网络切片需求信息包括以下2个网络性能指标：时延、可靠性，时延和可靠性的关联关系为：reliability＝99.9+(delay-50)*(10^(-3)*(1-10^(-(delay-50)/10)))。In another implementation, the reporting method is formula reporting. This formula is to fit the actual values of the two network performance indicators in the actual situation of each network slice subnet instance, and use mathematical formulas to express the correlation between the two network performance indicators. For example, network slicing requirement information includes the following two network performance indicators: delay and reliability. The correlation between delay and reliability is: reliability=99.9+(delay-50)*(10^(-3)*(1 -10^(-(delay-50)/10))).
在又一个实现中，上报方式为分段函数上报。例如，网络切片需求信息包括以下2个网络性能指标：时延、可靠性，时延和可靠性的关联关系为：throughput＝100，delay>＝200；throughput＝100-(200-delay)*0.2，100<＝delay<200。In another implementation, the reporting method is segmented function reporting. For example, network slicing requirement information includes the following two network performance indicators: latency and reliability. The correlation between latency and reliability is: throughput=100, delay>=200; throughput=100-(200-delay)*0.2 ,100<=delay<200.
S504.网络切片管理设备基于网络切片需求信息、相应的网络切片子网实例在各个指标上分别能达到的最优值以及关联关系，生成目标网络切片子网需求信息。S504. The network slicing management device generates target network slicing subnet demand information based on the network slicing demand information, the optimal values that the corresponding network slicing subnet instance can achieve on each indicator, and the correlation relationship.
具体地，网络切片管理设备根据网络切片需求信息、各网络切片子网实例中每个网络性能指标之间的关系、各网络切片子网实例在各项指标上分别能达到的最优值以及一个或多个关联信息，分解网络切片需求，得到目标网络切片子网需求信息。Specifically, the network slicing management device uses network slicing demand information, the relationship between each network performance indicator in each network slicing subnet instance, the optimal value that each network slicing subnet instance can achieve on each indicator, and a or multiple associated information, decompose network slicing requirements, and obtain target network slicing subnet requirement information.
网络切片管理设备根据网络切片需求信息、各网络切片子网实例中每个网络性能指标之间的关系以及各网络切片子网实例在各项指标上分别能达到的最优值，分解网络切片需求，可参考上述步骤S304、S402的描述。本实施例进一步地还根据各网络切片子网管理设备上报的一个或多个关联信息分解网络切片需求，生成目标网络切片子网需求信息。The network slicing management device decomposes the network slicing requirements based on the network slicing demand information, the relationship between each network performance indicator in each network slicing subnet instance, and the optimal values that each network slicing subnet instance can achieve on each indicator. , please refer to the description of steps S304 and S402 above. This embodiment further decomposes network slicing requirements based on one or more associated information reported by each network slicing subnet management device, and generates target network slicing subnet requirement information.
其中，根据上述关联信息生成目标网络切片子网需求信息，包括以下两种实现方式：Among them, the target network slice subnet requirement information is generated based on the above related information, including the following two implementation methods:
1)目标网络切片子网需求信息预验证。例如，网络切片子网管理设备1上报了时延、可靠性、吞吐量之间关联信息的数学表达式，网络切片管理设备给网络切片子网实例1分配时延50ms、可靠性99.999％、吞吐量80Mbps。再使用网络切片子网管理设备2上报的数学表达式检验该配置的合理性，发现网络切片子网实例1在达到时延50ms时，可靠性只能达到99.9％，吞吐率只能到50Mbps。那么网络切片管理设备会修改网络切片子网实例1的网络切片子网需求信息，例如适当提高网络切片子网实例1的时延指标，降低其他网络切片子网实例的时延指标。 1) Pre-verification of target network slice subnet requirement information. For example, the network slice subnet management device 1 reports the mathematical expression of the correlation information between delay, reliability, and throughput. The network slice management device assigns a delay of 50ms, a reliability of 99.999%, and a throughput to the network slice subnet instance 1. The amount is 80Mbps. Then we used the mathematical expression reported by the network slicing subnet management device 2 to test the rationality of the configuration. We found that when the network slicing subnet instance 1 reached a delay of 50ms, the reliability could only reach 99.9% and the throughput rate could only reach 50Mbps. Then the network slicing management device will modify the network slicing subnet demand information of network slicing subnet instance 1, for example, appropriately increase the delay index of network slicing subnet instance 1, and reduce the delay index of other network slicing subnet instances.
2)目标网络切片子网需求信息寻优。例如，网络切片管理设备综合各网络切片子网管理设备上报的时延、可靠性、吞吐量之间关联信息的数学表达式，利用求解该类优化问题的工具直接得到目标网络切片子网需求信息。2) Target network slicing subnet demand information optimization. For example, the network slicing management device integrates the mathematical expressions of the correlation information between delay, reliability, and throughput reported by each network slicing subnet management device, and uses tools to solve such optimization problems to directly obtain the target network slicing subnet demand information. .
上述目标网络切片子网需求信息的生成过程仅需要少量试错。以时延和可靠性指标为例，若某个网络切片子网实例的时延指标未达成，则在下一次生成目标网络切片子网需求信息的过程中提高时延阈值，同时可以根据时延和可靠性的关联信息增加可靠性的阈值，使生成的目标网络切片子网需求信息被网络切片子网实例接受的概率更大。The process of generating the target network slice subnet requirement information described above requires only a small amount of trial and error. Taking the delay and reliability indicators as an example, if the delay indicator of a certain network slice subnet instance is not reached, the delay threshold will be increased during the next generation of the target network slice subnet demand information. At the same time, the delay threshold can be increased based on the delay and reliability. Reliability related information increases the reliability threshold, making the generated target network slice subnet requirement information more likely to be accepted by the network slice subnet instance.
在上述能力查询中增加关联信息上报指示，已经在能力查询反馈中增加一个或多个关联信息，网络切片管理设备结合该一个或多个关联信息生成的目标网络切片子网需求信息，其可行性更高。可以减少生成目标网络切片子网需求信息所需的时间，降低各网络切片子网管理设备的***资源的消耗。Add related information reporting instructions to the above capability query. One or more related information has been added to the capability query feedback. The network slice management device combines the one or more related information to generate the target network slice subnet demand information. Its feasibility higher. It can reduce the time required to generate target network slice subnet demand information and reduce the consumption of system resources of each network slice subnet management device.
S505.网络切片管理设备向网络切片子网管理设备1、网络切片子网管理设备2分别发送网络切片子网实例创建请求。S505. The network slice management device sends network slice subnet instance creation requests to the network slice subnet management device 1 and the network slice subnet management device 2 respectively.
其中，该网络切片子网实例创建请求用于指示网络切片子网管理设备1、网络切片子网管理设备2基于各自的目标网络切片子网需求信息创建目标网络切片子网实例。该网络切片子网实例创建请求包括目标网络切片子网需求信息。The network slice subnet instance creation request is used to instruct the network slice subnet management device 1 and the network slice subnet management device 2 to create a target network slice subnet instance based on their respective target network slice subnet requirement information.

网络切片子网管理设备1、网络切片子网管理设备2分别根据网络切片子网实例创建请求，执行网络切片子网实例创建流程。示例性地，网络切片子网管理设备1基于第一目标网络切片子网需求信息，创建第一网络切片子网实例；网络切片子网管理设备2基于第二目标网络切片子网需求信息，创建第二网络切片子网实例。The network slice subnet management device 1 and the network slice subnet management device 2 respectively execute the network slice subnet instance creation process according to the network slice subnet instance creation request. Exemplarily, the network slice subnet management device 1 creates a first network slice subnet instance based on the first target network slice subnet requirement information; the network slice subnet management device 2 creates a first network slice subnet instance based on the second target network slice subnet requirement information.

S507.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送网络切片子网实例创建反馈。S507. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send network slice subnet instance creation feedback to the network slice management device.
其中，该网络切片子网实例创建反馈可以包括一个标识。其中，该标识可以是1比特。该1比特取值为“1”时，用于指示网络切片子网实例创建成功；该1比特取值为“0”时，用于指示网络切片子网实例创建失败。或者，该1比特取值为“0”时，用于指示网络切片子网实例创建成功；该1比特取值为“1”时，用于指示网络切片子网实例创建失败。The network slice subnet instance creation feedback may include an identifier. Wherein, the identifier may be 1 bit. When the value of this 1 bit is "1", it is used to indicate that the network slicing subnet instance was successfully created; when the value of this 1 bit is "0", it is used to indicate that the creation of the network slicing subnet instance failed. Alternatively, when the value of this 1 bit is "0", it is used to indicate that the network slicing subnet instance is successfully created; when the value of this 1 bit is "1", it is used to indicate that the creation of the network slicing subnet instance fails.
根据本申请实施例提供的一种网络管理方法，网络切片管理设备获取各网络切片子网实例的一个或多个网络性能指标分别能达到的最优值，以及各网络切片子网管理设备上报的多个网络性能指标之间的关联关系，基于该关联信息可获得网络切片子网实例的一个或多个网络性能指标分别能达到的实际值，从而根据该最优值和关联关系生成目标网络切片子网需求信息，并向网络切片子网管理设备发送该目标网络切片子网需求信息，网络切片子网管理设备根据该目标网络切片子网需求信息创建网络切片子网实例，提高了网络切片子网实例创建的成功率。According to a network management method provided by an embodiment of the present application, the network slice management device obtains the optimal values that can be achieved by one or more network performance indicators of each network slice subnet instance, and the optimal values reported by each network slice subnet management device.

The network slice subnet management device creates a network slice subnet instance based on the target network slice subnet demand information, which improves the network slice subnet The success rate of network instance creation.
如图6所示，为本申请实施例提供的又一种网络管理方法的流程示意图。该方法用于网络切片管理设备对网络切片实例进行管理，该网络切片实例有N个网络切片子网实例待创建，N≥2。在本实施例中，N＝2。示例性地，该方法可以包括以下步骤：As shown in Figure 6, it is a schematic flow chart of yet another network management method provided by an embodiment of the present application. This method is used by a network slicing management device to manage a network slicing instance. The network slicing instance has N network slicing subnet instances to be created, N≥2. In this embodiment, N=2. Exemplarily, the method may include the following steps:
S601.网络切片管理设备向各网络切片子网管理设备(图中示例了2个网络切片子网管理设备：网络切片子网管理设备1和网络切片子网管理设备2)分别发送能力查询请求。S601. The network slice management device sends capability query requests to each network slice subnet management device (the figure illustrates two network slice subnet management devices: network slice subnet management device 1 and network slice subnet management device 2).
该步骤的具体实现可参考上述步骤S301，在此不再赘述。 For the specific implementation of this step, reference can be made to the above-mentioned step S301, which will not be described again here.
S602.网络切片子网管理设备1、网络切片子网管理设备2收到能力查询请求后，分别获取相应的网络切片子网实例的静态能力信息。S602. After receiving the capability query request, the network slice subnet management device 1 and the network slice subnet management device 2 respectively obtain the static capability information of the corresponding network slice subnet instance.
示例性地，该静态能力信息指示相应的网络切片子网实例的一个或多个网络性能指标分别能达到的最优值。网络切片子网管理设备1、网络切片子网管理设备2分别评估各自对应的网络切片子网实例在各个指标上分别能达到的最优值。Illustratively, the static capability information indicates the optimal values that one or more network performance indicators of the corresponding network slice subnet instance can respectively achieve. The network slice subnet management device 1 and the network slice subnet management device 2 respectively evaluate the optimal values that their corresponding network slice subnet instances can achieve on each indicator.
该步骤的具体实现可参考上述步骤S302，在此不再赘述。For the specific implementation of this step, reference can be made to the above-mentioned step S302, which will not be described again here.
S603.网络切片子网管理设备1、网络切片子网管理设备2向网络切片管理设备分别发送能力查询反馈。S603. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send capability query feedback to the network slice management device.
该步骤的具体实现可参考上述步骤S303，在此不再赘述。For the specific implementation of this step, reference can be made to the above-mentioned step S303, which will not be described again here.
S604.网络切片管理设备根据网络切片需求信息和静态能力信息，生成初始网络切片子网需求信息。S604. The network slicing management device generates initial network slicing subnet demand information based on the network slicing demand information and static capability information.
该步骤的具体实现可参考上述步骤S304。由于网络切片管理设备是根据网络切片需求信息和静态能力信息生成的初始网络切片子网需求信息，该初始网络切片子网需求信息的可行性不高。For specific implementation of this step, please refer to the above-mentioned step S304. Since the network slice management device generates the initial network slice subnet requirement information based on the network slice requirement information and static capability information, the feasibility of the initial network slice subnet requirement information is not high.
可替换地，网络切片管理设备根据网络切片需求信息、静态能力信息和动态能力信息，生成初始网络切片子网需求信息。Alternatively, the network slicing management device generates initial network slicing subnet demand information based on the network slicing demand information, static capability information, and dynamic capability information.

S605.网络切片管理设备向网络切片子网管理设备1、网络切片子网管理设备2分别发送网络切片子网实例验证请求。S605. The network slice management device sends network slice subnet instance verification requests to the network slice subnet management device 1 and the network slice subnet management device 2 respectively.
由于网络切片管理设备生成目标网络切片子网需求信息后，要进行网络切片子网实例的创建，各网络切片子网管理设备接收到目标网络切片子网需求信息后，直接在物理网络上创建网络切片子网实例。如果该目标网络切片子网需求的可靠性低，某些网络切片子网实例不能达到网络切片子网需求，则要进行网络回退。本实施例在网络切片管理设备实际进行网络切片子网实例创建之前，进行网络切片子网需求信息的验证。即基于接收到的网络切片子网需求信息，验证各网络切片子网实例是否能达到各自的网络切片子网需求。Since the network slice management device generates the target network slice subnet demand information, it needs to create a network slice subnet instance. After receiving the target network slice subnet demand information, each network slice subnet management device directly creates a network on the physical network. Slice subnet instance. If the reliability of the target network slicing subnet requirement is low and some network slicing subnet instances cannot meet the network slicing subnet requirement, network rollback is required. In this embodiment, before the network slicing management device actually creates a network slicing subnet instance, the network slicing subnet requirement information is verified. That is, based on the received network slicing subnet requirement information, it is verified whether each network slicing subnet instance can meet its respective network slicing subnet requirement.
具体实现中，网络切片管理设备分别向网络切片子网管理设备1、网络切片子网管理设备2发送网络切片子网实例验证请求。其中，该网络切片子网实例验证请求包括：初始网络切片子网需求信息字段和执行(action)字段。初始网络切片子网需求信息字段用于指示初始网络切片子网需求信息，可以是上述SliceProfile。action字段用于指示网络切片管理设备需要各网络切片子网管理设备执行的操作。action字段可以为1比特，该1比特取值为“1”时，用于指示“验证(verify)”，即指示各网络切片子网管理设备根据初始网络切片子网需求信息验证各网络切片子网实例是否能达成该初始网络切片子网需求；该1比特取值为“0”时，用于指示“创建(deploy)”，即指示各网络切片子网管理设备根据目标网络切片子网需求信息创建网络切片子网实例。或者，该1比特取值为“0”时，用于指示“验证”；该1比特取值为“1”时，用于指示“创建(deploy)”。In specific implementation, the network slice management device sends a network slice subnet instance verification request to the network slice subnet management device 1 and the network slice subnet management device 2 respectively. Wherein, the network slice subnet instance verification request includes: an initial network slice subnet requirement information field and an execution (action) field. The initial network slice subnet requirement information field is used to indicate the initial network slice subnet requirement information, which can be the above-mentioned SliceProfile. The action field is used to indicate the operation that the network slice management device requires each network slice subnet management device to perform. The action field can be 1 bit. When the value of this 1 bit is "1", it is used to indicate "verify", that is, to instruct each network slice subnet management device to verify each network slice subnet based on the initial network slice subnet requirement information. Whether the network instance can meet the initial network slicing subnet requirements; when the value of this 1 bit is "0", it is used to indicate "deploy", that is, to instruct each network slicing subnet management device according to the target network slicing subnet requirements. Information to create a network slice subnet instance. Or, when the value of this 1 bit is "0", it is used to indicate "verification"; when the value of this 1 bit is "1", it is used to indicate "deploy".
在该验证环节，action字段用于指示“验证”。In this verification step, the action field is used to indicate "verification".
S606.网络切片子网管理设备1、网络切片子网管理设备2分别根据网络切片子网实例验证请求，验证相应的网络切片子网实例能否达成各自的初始网络切片子网需求。S606. The network slicing subnet management device 1 and the network slicing subnet management device 2 respectively verify whether the corresponding network slicing subnet instance can meet their respective initial network slicing subnet requirements according to the network slicing subnet instance verification request.
网络切片子网管理设备1、网络切片子网管理设备2分别接收到网络切片子网实例验证请求后，获取发给自身的初始网络切片子网需求信息和action字段。并且解析出action字段 指示“验证”。After receiving the network slice subnet instance verification request respectively, the network slice subnet management device 1 and the network slice subnet management device 2 obtain the initial network slice subnet requirement information and action field sent to themselves. And parse out the action field Indicates "verify".
则网络切片子网管理设备1、网络切片子网管理设备2可以通过仿真或数学计算验证各自的网络切片子网实例是否能达成对应的初始网络切片子网需求。Then the network slicing subnet management device 1 and the network slicing subnet management device 2 can verify through simulation or mathematical calculation whether their respective network slicing subnet instances can meet the corresponding initial network slicing subnet requirements.
S607.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送网络切片子网实例验证反馈。S607. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send network slice subnet instance verification feedback to the network slice management device.
相应地，网络切片管理设备分别接收网络切片子网管理设备1、网络切片子网管理设备2发送的网络切片子网实例验证反馈。该网络切片子网实例验证反馈包括网络切片子网实例验证结果。Correspondingly, the network slice management device receives the network slice subnet instance verification feedback sent by the network slice subnet management device 1 and the network slice subnet management device 2 respectively. The network slice subnet instance verification feedback includes the network slice subnet instance verification results.
其中，该网络切片子网实例验证结果用于指示各网络切片子网管理设备的网络切片子网实例在仿真或数学计算等验证方法中，能否达成该网络切片子网实例对应的初始网络切片子网需求。示例性地，该网络切片子网实例验证结果可以是第一标识。该第一标识可以为1比特。该1比特取值为“1”时，用于指示该网络切片子网实例能达成对应的初始网络切片子网需求；该1比特取值为“0”时，用于指示该网络切片子网实例不能达成对应的初始网络切片子网需求。或者，该1比特取值为“0”时，用于指示该网络切片子网实例能达成对应的初始网络切片子网需求；该1比特取值为“1”时，用于指示该网络切片子网实例不能达成对应的初始网络切片子网需求。Among them, the network slice subnet instance verification result is used to indicate whether the network slice subnet instance of each network slice subnet management device can achieve the initial network slice corresponding to the network slice subnet instance in verification methods such as simulation or mathematical calculations. Subnet requirements. For example, the network slice subnet instance verification result may be the first identification. The first identifier may be 1 bit. When the value of this 1 bit is "1", it is used to indicate that the network slicing subnet instance can meet the corresponding initial network slicing subnet requirements; when the value of this 1 bit is "0", it is used to indicate that the network slicing subnet The instance cannot meet the corresponding initial network slicing subnet requirements. Or, when the value of this 1 bit is "0", it is used to indicate that the network slice subnet instance can meet the corresponding initial network slicing subnet requirements; when the value of this 1 bit is "1", it is used to indicate that the network slice The subnet instance cannot meet the corresponding initial network slicing subnet requirements.
当各网络切片子网管理设备发送的网络切片子网实例验证结果指示均能达成网络切片子网实例对应的初始网络切片子网需求时，则执行下述步骤S608；当任一个网络切片子网管理设备发送的网络切片子网实例验证结果用于指示不能达成网络切片子网实例对应的初始网络切片子网需求时，则继续执行步骤S604～S607，且网络切片管理设备根据网络切片子网管理设备1、网络切片子网管理设备2分别发送的网络切片子网实例验证结果，重新生成网络切片子网需求信息，并网络切片子网管理设备1、网络切片子网管理设备2分别发送重新生成的网络切片子网需求信息。重复上述过程，直到各网络切片子网管理设备发送的网络切片子网实例验证结果指示能达成网络切片子网实例对应的重新生成的网络切片子网需求。When the network slice subnet instance verification result indications sent by each network slice subnet management device can meet the initial network slice subnet requirements corresponding to the network slice subnet instance, the following step S608 is executed; when any network slice subnet When the network slice subnet instance verification result sent by the management device is used to indicate that the initial network slice subnet requirements corresponding to the network slice subnet instance cannot be met, steps S604 to S607 are continued, and the network slice management device manages according to the network slice subnet The network slice subnet instance verification results sent by device 1 and network slice subnet management device 2 respectively regenerate the network slice subnet requirement information, and the network slice subnet management device 1 and network slice subnet management device 2 respectively send the regenerated Network slicing subnet requirement information. The above process is repeated until the network slice subnet instance verification result indication sent by each network slice subnet management device can meet the regenerated network slice subnet requirements corresponding to the network slice subnet instance.
由于图3所示实施例中各网络切片子网管理设备能力查询反馈中上报的信息(相应的网络切片子网实例在各个指标上分别能达到的最优值)不足以支持网络切片管理设备通过少量次数的尝试就得到各目标网络切片子网实例能够接受的目标网络切片子网需求信息。在图3所示的实施例中，网络切片管理设备直接将生成的目标网络切片子网需求信息发送给各网络切片子网管理设备，网络切片子网管理设备在物理网络上创建网络切片子网实例，这样既耗时又存在很大风险。在本实施例中，网络切片需求信息验证步骤帮助网络切片管理设备过滤掉一部分存在一个或多个网络切片子网实例可能无法达成的网络切片子网需求，各网络切片子网管理设备仅需要根据网络切片需求信息验证通过的目标网络切片子网需求信息，在物理网络上创建网络切片子网实例，从而降低时间消耗、对网络上其他业务的影响和网络回退的代价。Since the information reported in the capability query feedback of each network slice subnet management device in the embodiment shown in Figure 3 (the optimal value that the corresponding network slice subnet instance can achieve on each indicator) is not enough to support the network slice management device through After a small number of attempts, the target network slice subnet requirement information that each target network slice subnet instance can accept is obtained. In the embodiment shown in Figure 3, the network slice management device directly sends the generated target network slice subnet requirement information to each network slice subnet management device, and the network slice subnet management device creates a network slice subnet on the physical network. For example, this is time-consuming and risky. In this embodiment, the network slicing requirement information verification step helps the network slicing management device filter out some network slicing subnet requirements that may not be met by one or more network slicing subnet instances. Each network slicing subnet management device only needs to Based on the target network slicing subnet requirement information that has passed the network slicing requirement information verification, a network slicing subnet instance is created on the physical network, thereby reducing time consumption, impact on other services on the network, and the cost of network rollback.

The difference is that through the above verification process of network slicing subnet requirement information, the success rate of network slicing subnet instance creation is improved.

与图5所示实施例不同的是，该实施例还包括下述验证环节：步骤S704～S707：What is different from the embodiment shown in Figure 5 is that this embodiment also includes the following verification steps: steps S704 to S707:
S704.网络切片管理设备根据网络切片需求信息和静态能力信息，生成初始网络切片需求信息。S704. The network slicing management device generates initial network slicing requirement information based on the network slicing requirement information and static capability information.
S705.网络切片管理设备向网络切片子网管理设备1、网络切片子网管理设备2分别发送网络切片子网实例验证请求。S705. The network slice management device sends network slice subnet instance verification requests to the network slice subnet management device 1 and the network slice subnet management device 2 respectively.
S706.网络切片子网管理设备1、网络切片子网管理设备2分别根据网络切片子网实例验证请求，验证相应的网络切片子网实例能否达成初始网络切片子网需求。S706. The network slicing subnet management device 1 and the network slicing subnet management device 2 respectively verify whether the corresponding network slicing subnet instance can meet the initial network slicing subnet requirements according to the network slicing subnet instance verification request.
S707.网络切片子网管理设备1、网络切片子网管理设备2分别向网络切片管理设备发送网络切片子网实例验证反馈。 S707. The network slice subnet management device 1 and the network slice subnet management device 2 respectively send network slice subnet instance verification feedback to the network slice management device.
相应地，网络切片管理设备分别接收网络切片子网管理设备1、网络切片子网管理设备2发送的网络切片子网实例验证反馈。该网络切片子网实例验证包括网络切片子网实例验证结果。Correspondingly, the network slice management device receives the network slice subnet instance verification feedback sent by the network slice subnet management device 1 and the network slice subnet management device 2 respectively. The network slice subnet instance verification includes network slice subnet instance verification results.
其中，S704～S707的具体实现可参考步骤S604～S607。所不同的是，由于在步骤S703中，各网络切片子网管理设备还上报了一个或多个关联信息，网络切片管理设备根据网络切片需求信息、各网络切片子网实例中的每个网络性能指标之间的关系、各网络切片子网实例在各项指标上能达到的最优值以及一个或多个关联信息，生成网络切片子网需求信息，提高了目标网络切片子网需求信息的可行性，可以减少验证循环的次数。Among them, the specific implementation of S704 to S707 may refer to steps S604 to S607. The difference is that, in step S703, each network slice subnet management device also reports one or more associated information, and the network slice management device determines the network performance of each network slice subnet instance based on the network slice requirement information and the network performance of each network slice subnet instance. The relationship between indicators, the optimal value that each network slicing subnet instance can achieve on each indicator, and one or more associated information generate network slicing subnet demand information, which improves the feasibility of the target network slicing subnet demand information. properties, which can reduce the number of verification cycles.
另外，与步骤S607不同的是，在步骤S707中，该网络切片子网实例验证结果除了包括第一标识，还包括相应的网络切片子网实例的多个网络性能指标的实际达成情况与该网络切片子网实例的初始网络切片子网需求之间的差。In addition, what is different from step S607 is that in step S707, the network slice subnet instance verification result not only includes the first identifier, but also includes the actual achievement of multiple network performance indicators of the corresponding network slice subnet instance and the network The difference between the initial network slicing subnet requirements for the slicing subnet instance.
示例性地，可以用指标达成情况列表<指标名称，差>的格式表示相应的网络切片子网实例的多个网络性能指标的实际达成情况与该网络切片子网实例的初始网络切片子网需求之间的差。For example, the actual achievement of multiple network performance indicators of the corresponding network slicing subnet instance and the initial network slicing subnet requirement of the network slicing subnet instance can be expressed in the format of an indicator achievement list <indicator name, difference> difference between.
如果第一标识用于指示网络切片子网实例能达成的初始网络切片子网需求，则该相差值指的是验证环境下的指标值优于初始网络切片子网需求(用正数表达)。如果第一标识用于指示网络切片子网实例不能达成初始网络切片子网需求，则该相差值指的是验证环境下指标值差于初始网络切片子网需求的量(用负数表达)。If the first identifier is used to indicate the initial network slicing subnet requirement that the network slicing subnet instance can achieve, then the difference value means that the indicator value in the verification environment is better than the initial network slicing subnet requirement (expressed as a positive number). If the first identifier is used to indicate that the network slicing subnet instance cannot meet the initial network slicing subnet requirement, the difference value refers to the amount (expressed as a negative number) that the indicator value in the verification environment is different from the initial network slicing subnet requirement.
当该网络切片子网实例验证结果指示能达成网络切片子网实例的初始网络切片子网需求时，则执行下述步骤S708；当该网络切片子网实例验证结果用于指示不能达成网络切片子网实例的初始网络切片子网需求时，则继续执行步骤S704～S707，且网络切片管理设备根据网络切片子网管理设备1、网络切片子网管理设备2分别发送的网络切片子网实例验证结果，重新生成网络切片子网需求信息，直到网络切片子网实例验证结果指示能达成网络切片子网实例的重新生成的网络切片子网需求。When the verification result of the network slicing subnet instance indicates that the initial network slicing subnet requirement of the network slicing subnet instance can be met, the following step S708 is performed; when the verification result of the network slicing subnet instance indicates that the initial network slicing subnet requirement of the network slicing subnet instance cannot be met, When the initial network slice subnet of the network instance is required, steps S704 to S707 are continued, and the network slice management device verifies the network slice subnet instance verification results respectively sent by the network slice subnet management device 1 and the network slice subnet management device 2. , regenerate the network slicing subnet requirement information until the network slicing subnet instance verification result indicates that the regenerated network slicing subnet requirement of the network slicing subnet instance can be achieved.
上述相应的网络切片子网实例的多个网络性能指标的实际达成情况与网络切片子网实例的初始网络切片子网需求之间的相差值可以进一步指导步骤S704的操作。例如网络切片子网管理设备1上报的网络切片需求信息达成反馈为(0，<delay,-5ms，reliability，0.001％，throughput，5Mbps>)，其中第一标识取值为“0”表示网络切片子网管理设备1没达成网络切片管理设备分配的初始网络切片子网需求，具体是实际时延比初始网络切片子网需求规定的多了5ms，可靠性比初始网络切片子网需求规定的高了0.001％，以及吞吐率比初始网络切片子网需求规定的大了5Mbps。网络切片管理设备得到该信息后可以在下一次分配方案中将网络切片子网管理设备1的时延指标上调5ms。The difference value between the actual achievement of multiple network performance indicators of the corresponding network slicing subnet instance and the initial network slicing subnet requirement of the network slicing subnet instance can further guide the operation of step S704. For example, the network slicing requirement information reported by the network slicing subnet management device 1 is (0, <delay, -5ms, reliability, 0.001%, throughput, 5Mbps>), where the first identifier value is "0" indicating network slicing. Subnet management device 1 did not meet the initial network slicing subnet requirements allocated by the network slicing management device. Specifically, the actual delay was 5ms longer than the initial network slicing subnet requirements, and the reliability was higher than the initial network slicing subnet requirements. 0.001%, and the throughput is 5Mbps greater than specified by the initial network slicing subnet requirements. After obtaining this information, the network slice management device can increase the delay indicator of the network slice subnet management device 1 by 5 ms in the next allocation plan.
S708.网络切片管理设备向网络切片子网管理设备1、网络切片子网管理设备2分别发送网络切片子网实例创建请求。S708. The network slice management device sends a network slice subnet instance creation request to the network slice subnet management device 1 and the network slice subnet management device 2 respectively.
该步骤的具体实现可参考步骤S505或S608，在此不再赘述。For the specific implementation of this step, please refer to step S505 or S608, which will not be described again here.
