The next-generation network not only needs to provide ultra-high traffic for various scenarios such as dense residential areas, offices, stadiums, open-air gatherings, subways, expressways, and high-speed rails. Density, ultra-high connection density, and ultra-high mobility. It is also necessary to provide users with ultra-high-definition video, virtual reality, augmented reality, cloud desktop, online games, and other extreme service experiences. Network services have become more colorful. The next generation network puts more emphasis on user experience, and needs to support a variety of business needs to meet people's diverse business needs in terms of living, working, leisure and transportation.
由于传统无线网络是静态僵化的，无法根据无线网络中的业务量以及无线网络环境的变化，动态地做出网络规划，提高网络资源利用率，提升用户体验。针对该问题，LTE(Long Term Evolution，长期演进)中引入SON(Self-Organization Network，自组织网络)，利用SON的自我配置、自我优化和自我规划的特性，实现基站的即插即用、软件的自动升级、无线网络参数的自动配置、连接关系的自动检测与管理，减少了人为干预，提升了基站的能源利用率；同时根据网络设备运行状况，自适应调整网络参数，优化网络性能，并通过自动报警功能，及时发现故障基站，并对其进行及时隔离与恢复，降低了网络的运维成本，提高了网络服务质量。通过自主感知无线网络状态和网络性能，输出网络参数配置方案和网络控制策略，实现网络的自配置、自优化与自治愈，提升网络自组织能力。Because the traditional wireless network is static and rigid, it is impossible to dynamically make network planning according to the traffic volume in the wireless network and the change of the wireless network environment, so as to improve the utilization rate of network resources and improve user experience. In response to this problem, LTE (Long Term Evolution, long-term evolution) introduces SON (Self-Organization Network, self-organizing network), and utilizes the characteristics of self-configuration, self-optimization and self-planning of SON to realize plug-and-play, software Automatic upgrade of wireless network parameters, automatic detection and management of connection relationships, reducing human intervention and improving the energy efficiency of base stations; at the same time, according to the operating status of network equipment, adaptively adjust network parameters, optimize network performance, and Through the automatic alarm function, the faulty base station can be found in time, and it can be isolated and recovered in time, which reduces the operation and maintenance cost of the network and improves the quality of network service. By autonomously sensing wireless network status and network performance, outputting network parameter configuration schemes and network control strategies, realizing network self-configuration, self-optimization and self-healing, and improving network self-organization capabilities.
虽然SON技术能够减少人为干预，自主感知无线网络，输出网络参数配置方案，但是下一代网络更加强调以用户体验为中心，需要支持多种多样的业务需求，而SON技术对用户业务需求的适应性比较低。Although SON technology can reduce human intervention, autonomously sense the wireless network, and output network parameter configuration solutions, the next-generation network places more emphasis on user experience and needs to support a variety of business needs, and the adaptability of SON technology to user business needs relatively low.

IMT2020(5G推进组)将下一代网络中的业务场景分为四种典型业务场景，分别为：广域无缝覆盖业务、热点高容量业务、低时延高可靠业务和低功耗大连接业务，基于此，本发明实施例中，将无线网络切片分为相应的四种典型无线网络切片，分别为：广域无缝覆盖切片、热点高容量切片、低功耗大连接切片和低时延高可靠切片。IMT2020 (5G Promotion Group) divides business scenarios in next-generation networks into four typical business scenarios, namely: wide-area seamless coverage services, hotspot high-capacity services, low-latency high-reliability services, and low-power large-connection services Based on this, in the embodiment of the present invention, wireless network slices are divided into corresponding four typical wireless network slices, namely: wide-area seamless coverage slices, hotspot high-capacity slices, low-power large-connection slices, and low-latency slices. Highly reliable slicing.
广域无缝覆盖切片以保证用户的移动性和业务连续性为目标，为用户提供无缝的高速移动业务体验，保证100兆比特每秒以上的用户体验速率。对于切片的配置，可以采用超大规模宏基站或者分布式天线配置，追求无缝覆盖，服务非热点区域移动用户的通信。Wide-area seamless coverage slices aim to ensure user mobility and business continuity, provide users with seamless high-speed mobile service experience, and ensure a user experience rate of more than 100 Mbits per second. For slice configuration, ultra-large-scale macro base stations or distributed antenna configurations can be used to pursue seamless coverage and serve communications for mobile users in non-hotspot areas.
热点高容量切片主要面向局部热点区域，为用户提高极高的数据传输速率，需要提供1吉比特每秒用户体验速率、数十吉比特每秒峰值速率和数十万亿比特每秒每平方公里流量密度。该类切片将采用大规模天线、集中式云无线接入、或异构聚合技术，目的是提升无线传输速率。Hotspot high-capacity slicing is mainly aimed at local hotspot areas to increase the extremely high data transmission rate for users.

This type of slice can use local cache F-AP (Fog Access Point, fog access node) or terminal direct connection. F-AP has a front-end radio frequency signal and symbol processing module, as well as a baseband signal physical processing and radio resource management control module. The purpose is to reduce forwarding delay and improve link reliability.

The access network slice orchestrator first determines whether the slice type selected for the user is a single mode or a mixed mode.

当用户的业务满足以上四种网络切片当中两种或两种以上网络切片的任一特征时，确定网络切片为混合模式的网络切片，混合模式由满足特征的这几种切片组成，例如：当用户的业务满足低时延和大连接时，确定网络切片为低功耗大连接和低时延高可靠两种混合模式的网络切片。When the user's business meets any of the characteristics of two or more network slices among the above four types of network slices, the network slice is determined to be a mixed-mode network slice, and the mixed mode is composed of these types of slices that meet the characteristics, for example: when When the user's business meets low latency and large connections, the network slice is determined to be a mixed mode of low power consumption large connections and low latency and high reliability.
具体的，接入网切片编排器依次判断业务的可靠性、时延、该类型终端接入网络数量是否达到百万级别、终端的功耗、传输速率大小以及终端所处位置是否为热点区域，依次输出业务的特征(高可靠、低时延、大连接、低功耗等)。业务的性能需同时满足低时延和高可靠要求，用户才可以接入低时延高可靠切片。同理，业务的性能需同时满足低功耗和大连接，用户才可以接入低功耗大连接切片。当业务的性能只满足热点高容量需求时，则接入热点高容量切片。当业务的性能满足广域无缝覆盖时，则用户接入广域无缝覆盖切片；当所述用户的业务满足以上四种切片当中两种或两种以上切片的任一特征时，确定所述网络切片为混合模式的网络切片，混合模式由满足特征的这几种切片组成，例如：业务的性能满足低时延和大连接时，则用户接入低功耗大连接和低时延高可靠这两种混合模式的网络切片。实际应用中，接入网络切片的种类可以有很多种，这里不一一列举。Specifically, the access network slice orchestrator sequentially judges the reliability of the service, the delay, whether the number of access networks of this type of terminal reaches the million level, the power consumption of the terminal, the transmission rate, and whether the location of the terminal is a hotspot area. The characteristics of the service (high reliability, low delay, large connection, low power consumption, etc.) are output sequentially. The performance of the service must meet the requirements of low latency and high reliability at the same time, so that users can access slices with low latency and high reliability. In the same way, the performance of the business must meet both low power consumption and large connections, so that users can access low-power consumption and large connection slices. When the performance of the business only meets the high-capacity demand of the hotspot, access the high-capacity slice of the hotspot. When the performance of the service satisfies the wide-area seamless coverage, the user accesses the wide-area seamless coverage slice; The network slicing described above is network slicing in mixed mode. The mixed mode is composed of these slices that meet the characteristics. For example, when the service performance meets the requirements of low latency and large Reliable network slicing for these two hybrid models. In practical applications, there are many types of access network slices, which are not listed here.
在步骤S103中确定网络切片的种类为广域无缝覆盖切片时，确定广域无缝覆盖切片的配置方案，参见图4，图4为本发明实施例的广域无缝覆盖切片的配置方案示意图，包括如下步骤：When it is determined in step S103 that the type of network slice is a wide-area seamless coverage slice, the configuration scheme of the wide-area seamless coverage slice is determined, see FIG. 4 , which shows the configuration scheme of the wide-area seamless coverage slice according to an embodiment of the present invention Schematic diagram, including the following steps:
步骤S401，获取用户的移动速率和用户的业务类型。Step S401, acquiring the user's moving rate and the user's service type.
步骤S402，判断用户的移动速率是否大于网络预定门限值M1。Step S402, judging whether the mobile speed of the user is greater than the predetermined threshold value M1 of the network.
如果用户的移动速率大于网络预定门限值M1，执行步骤S403，网络切片的配置方案中的组网方式为用户接入HPN(High Power Node，大功率节点)。If the mobile speed of the user is greater than the predetermined threshold M1 of the network, step S403 is executed, and the networking mode in the network slicing configuration scheme is that the user accesses a HPN (High Power Node, high-power node).
如果用户的移动速率小于或等于网络预定门限值M1，执行步骤S404，判断用户的业务类型是否为数据业务。If the mobile speed of the user is less than or equal to the predetermined threshold M1 of the network, step S404 is executed to determine whether the service type of the user is a data service.
如果用户的业务类型为数据业务，执行步骤S405，网络切片的配置方案中的组网方式为用户的控制面接入大功率节点，用户的数据面接入RRH(Remote Radio Head，远端射频单元)。If the service type of the user is a data service, step S405 is performed, and the networking mode in the network slicing configuration scheme is that the user's control plane is connected to a high-power node, and the user's data plane is connected to an RRH (Remote Radio Head, remote radio unit).
如果用户的业务类型不是数据业务，执行步骤S403，网络切片的配置方案中的组网方式为用户接入HPN。If the service type of the user is not a data service, step S403 is executed, and the networking mode in the network slicing configuration scheme is that the user accesses the HPN.
具体的，接入网切片编排器首先判断用户的移动速率是否大于网络预定门限值M1，其中，网络预定门限值M1可以为500km/h，也可以是根据实际情况设定的其他值，在此不做限定。如果大于该预定门限值M1，则说明用户处于高速移动状态，为了降低用户的小区频繁切换程度和掉话率，采用直接接入HPN模式。或者，如果用户移动速率小于预定门限值M1，接入网切片编排器进一步判断用户发起的业务请求是否为数据业务，如果不是数据业务而是语音业务，则为用户选择直接入HPN模式。如果用户发起数据业务，则用户的控制面接入HPN，而数据面接入RRH，由HPN实现对用户的控制管理，降低用户的小区频繁切换次数与掉话率，即便用户处于小区边缘或高速移动中也不会导致用户的业务不连续，而RRH则保证用户的体验速率始终大于100兆比特每秒。需要说明的是，本发明实施例中的HPN可以是传统的宏基站、配置有大规模天线的增强型宏基站或者与基站，HPN具有完整的物理层、数据链路层和网络层功能，其可以利用自身配置的无线射频发射装置和基带处理装置完成业务数据和控制信息处理功能，并提供业务数据和/或控制信令。RRH则只保留有前端无线射频信号和简单的符号处理功能，其余的基带信号物理处理与无线资源管理控制功能则都集中在大规模云计算服务器中的BBU(Building Base band Unit，基带处理单元)池中的接入层中。Specifically, the access network slice orchestrator first judges whether the mobile speed of the user is greater than the predetermined network threshold value M1, wherein the predetermined network threshold value M1 may be 500 km/h, or other values set according to actual conditions, It is not limited here. If it is greater than the predetermined threshold M1, it means that the user is in a high-speed mobile state. In order to reduce the frequency of cell switching and call drop rate of the user, the direct access HPN mode is adopted. Or, if the mobile speed of the user is less than the predetermined threshold M1, the access network slice orchestrator further judges whether the service request initiated by the user is a data service, and if it is not a data service but a voice service, then directly enters the HPN mode for the user. If a user initiates a data service, the user's control plane is connected to the HPN, and the data plane is connected to the RRH. The HPN realizes the control and management of the user, reducing the number of frequent cell handovers and the drop rate of the user, even if the user is at the edge of the cell or moving at a high speed It will not cause the user's service to be discontinuous, and the RRH ensures that the user's experience rate is always greater than 100 Mbits per second. It should be noted that the HPN in the embodiment of the present invention can be a traditional macro base station, an enhanced macro base station equipped with a large-scale antenna, or a base station. The HPN has complete physical layer, data link layer, and network layer functions. It can use its self-configured radio frequency transmitting device and baseband processing device to complete service data and control information processing functions, and provide service data and/or control signaling. RRH only retains the front-end radio frequency signal and simple symbol processing functions, and the rest of the baseband signal physical processing and radio resource management control functions are concentrated in the BBU (Building Base band Unit, baseband processing unit) in the large-scale cloud computing server. In the access layer in the pool.

步骤S501，获取终端对应的用户的社交关系、终端的位置、区域的业务分布。Step S501, acquiring the social relationship of the user corresponding to the terminal, the location of the terminal, and the service distribution in the area.
步骤S502，将区域中重复请求次数大于业务下发门限值N1的业务请求发送至F-AP。Step S502, sending the service requests whose number of repeated requests in the area is greater than the service delivery threshold N1 to the F-AP.
步骤S503，判断终端是否具备终端直通通信能力。Step S503, judging whether the terminal has the terminal direct communication capability.
如果终端具备终端直通通信能力，执行步骤S504，判断区域中用户之外的其他用户是否有该业务请求。If the terminal has the terminal direct communication capability, step S504 is executed to determine whether other users in the area have the service request.
如果区域中其他用户有该业务请求，执行步骤S505，判断终端与其他终端之间的距离是否小于终端直通模式的距离门限值D1。If other users in the area have the service request, step S505 is executed to determine whether the distance between the terminal and other terminals is smaller than the distance threshold D1 of the terminal direct mode.
如果终端与其他终端之间的距离小于终端直通模式的距离门限值D1，执行步骤S506，判断用户之间是否具有社交关系。If the distance between the terminal and other terminals is smaller than the distance threshold D1 of the terminal direct mode, step S506 is executed to determine whether there is a social relationship between the users.
如果用户之间具有社交关系，执行步骤S507，网络切片的配置方案中的组网方式为终端直通模式。If there is a social relationship between the users, step S507 is executed, and the networking mode in the network slicing configuration solution is terminal direct mode.
如果区域中其他用户没有该业务请求、判断终端与其他终端之间的距离大于或等于终端直通模式的距离门限值D1、用户之间没有社交关系、或终端不具备终端直通通信能力，执行步骤S508，判断业务的历史请求次数是否大于业务下发门限值N1。Step S508, judging whether the historical request times of the service is greater than the service delivery threshold N1.
如果业务的历史请求次数大于业务下发门限值N1，执行步骤S509，网络切片的配置方案中的组网模式为用户接入雾接入节点。If the number of historical service requests is greater than the service delivery threshold N1, step S509 is executed, and the networking mode in the network slicing configuration scheme is user access to fog access nodes.
如果业务的历史请求次数小于或等于业务下发门限值，执行步骤S510，网络切片的配置方案中的组网方式为用户接入云无线接入网络。If the number of historical service requests is less than or equal to the service delivery threshold, step S510 is executed, and the networking mode in the network slicing configuration scheme is user access to the cloud wireless access network.
具体的，接入网切片编排器首先获取区域的业务分布，将重复请求次数大于N1的业务发送至F-AP中，接入网切片编排器首先判断该终端是否具备终端直通通信能力。如果具备，则进一步判断区域中其他用户是否有该用户所请求的业务，如果有，则判断终端与其他终端之间的距离是否小于终端直通模式的距离门限值D1。其中，该距离门限值D1可以是100m，也可以是根据实际情况设定的其他值，在此不做限定。如果终端与其他终端之间的距离满足终端直通模式的距离，判断用户之间是否具有社交关系，如果具有社交关系，则可以采用终端直通模式进行组网通信。或者，如果该用户不具备终端直通通信能力，进一步地，如果区域没有用户有该用户所请求业务，则接入网切片编排器判断该业务重复请求次数是否大于业务下发门限值N1，业务下发门限值N1可以是该业务历史请求次数占比该区域所有业务请求次数的前20％，该门限值可根据无线网络中的缓存大小进行调整，若缓存空间较大，则可以提高门限值以缓存更多业务，反之，则需降低门限值保证无线网络的缓存空间。如果业务下发次数大于门限值，则该用户可接入F-AP。或者，如果该业务请求次数小于业务下发门限值N1，则该用户接入C-RAN(Clound-Radio Access Network，云无线接入网络)，由RRH完成业务数据的收发和简单处理，并通过前向链路回传到BBU池中，利用BBU池的协作信号处理和集中资源调度。用户通过终端直通模式或接入F-AP均可以降低业务传输时延，同时可以减轻C-RAN模式中BBU池与RRH之间的前向链路容量。本发明实施例的F-AP不仅具有传统RRH的前端无线射频信号和简单的符号处理模块，也具有基带信号物理处理和无线资源管理控制模块，同时还配备有内容缓存器。本发明实施例的C-RAN是由基带处理单元BBU和远端无线射频单元RRH组成的，其中，RRH只保留前端无线射频信号和简单的符号处理功能，其余的基带信号物理处理和无线资源管理控制功能都集中在大规模云计算服务器中的BBU池中。Specifically, the access network slice orchestrator first obtains the service distribution in the area, and sends the service with the number of repeated requests greater than N1 to the F-AP, and the access network slice orchestrator first judges whether the terminal has direct terminal communication capability. If so, it further judges whether other users in the area have the service requested by the user, and if so, judges whether the distance between the terminal and other terminals is smaller than the distance threshold D1 of the terminal direct mode. Wherein, the distance threshold D1 may be 100 m, or other values set according to actual conditions, which are not limited here. If the distance between the terminal and other terminals satisfies the distance of the terminal direct mode, it is judged whether there is a social relationship between the users. If there is a social relationship, the terminal direct mode can be used for networking communication. Or, if the user does not have the terminal direct communication capability, further, if there is no user in the area that has the service requested by the user, then the access network slice orchestrator judges whether the number of repeated requests for the service is greater than the service delivery threshold N1, and the service The delivery threshold N1 can be the top 20% of the historical service requests in this area. This threshold can be adjusted according to the cache size in the wireless network. If the cache space is large, it can be increased. The threshold value needs to be lowered to buffer more services, otherwise, the threshold value needs to be lowered to ensure the buffering space of the wireless network. If the number of service delivery times is greater than the threshold, the user can access the F-AP. Or, if the number of service requests is less than the service delivery threshold N1, the user accesses the C-RAN (Clound-Radio Access Network, Cloud Radio Access Network), and the RRH completes the sending and receiving of service data and simple processing, and Backhaul to the BBU pool through the forward link, and use the cooperative signal processing and centralized resource scheduling of the BBU pool. Users can reduce the service transmission delay through the terminal direct mode or access the F-AP, and at the same time reduce the forward link capacity between the BBU pool and the RRH in the C-RAN mode. The F-AP of the embodiment of the present invention not only has the front-end radio frequency signal of the traditional RRH and a simple symbol processing module, but also has a baseband signal physical processing and radio resource management control module, and is also equipped with a content buffer. The C-RAN in the embodiment of the present invention is composed of a baseband processing unit BBU and a remote radio frequency unit RRH, wherein the RRH only retains front-end radio frequency signals and simple symbol processing functions, and the rest of the baseband signal physical processing and radio resource management The control functions are all concentrated in the BBU pool in the large-scale cloud computing server.

According to the cache of the terminal, step S604 is executed to determine whether the terminal is a cluster head, wherein the terminal forms a cluster with other terminals.
如果该终端不是簇头，执行步骤S605，网络切片的配置方案为将该终端的信息传送至簇头。If the terminal is not the cluster head, step S605 is executed, and the configuration scheme of the network slice is to transmit the information of the terminal to the cluster head.
如果终端不具备终端直通通信能力、或终端与其他终端之间的距离大于终端直通模式的距离门限值D1、或该终端为簇头，执行步骤S606，判断终端节点是否在雾接入节点覆盖范围内。If the terminal does not have the terminal direct communication capability, or the distance between the terminal and other terminals is greater than the distance threshold value D1 of the terminal direct mode, or the terminal is a cluster head, perform step S606 to determine whether the terminal node is covered by the fog access node within range.
如果该终端节点在雾接入节点覆盖范围内，执行步骤S607，网络切片的配置方案中的组网模式为用户接入雾接入节点。If the terminal node is within the coverage of the fog access node, step S607 is executed, and the networking mode in the network slicing configuration scheme is user access to the fog access node.
如果该终端节点不在雾接入节点覆盖范围内，执行步骤S608，网络切片的配置方案中的组网模式为用户接入大功率节点。If the terminal node is not within the coverage of the fog access node, step S608 is executed, and the networking mode in the configuration scheme of network slicing is user access to a high-power node.
具体的，接入网切片编排器判断该终端是否具有终端直通通信能力，如果具备，进一步判断该终端与其它终端之间的距离是否大于终端直通模式的距离门限值D1，如果该终端与其它终端距离小于或等于终端直通模式的距离门限值D1，进一步判断该终端是否为簇头，如果不是簇头，则该终端的信息传至簇头即可。如果该终端不具备终端直通通信能力、该终端与其它终端距离大于终端直通模式的距离门限值D1、或该终端是簇头，进一步判断该终端节点是否在F-AP覆盖范围，如果是，则直接接入F-AP；如果否，则接入HPN。具有动态组网能力的终端节点，可以在HPN或F-AP的控制下，通过终端直通方式，构成无线网状网Mesh拓扑、树状拓扑或者星型拓扑结构，具有缓存能力的节点可以作为分簇节点，这种方式可以使更多终端能够接入网络，提升网络的连接数密度。Specifically, the access network slice arranger judges whether the terminal has the terminal direct communication capability, and if so, further judges whether the distance between the terminal and other terminals is greater than the distance threshold value D1 of the terminal direct mode. If the terminal distance is less than or equal to the distance threshold D1 of the terminal direct mode, it is further judged whether the terminal is a cluster head. If not, the information of the terminal can be transmitted to the cluster head. If the terminal does not have the terminal direct communication capability, the distance between the terminal and other terminals is greater than the distance threshold D1 of the terminal direct mode, or the terminal is a cluster head, further determine whether the terminal node is within the coverage of the F-AP, and if so, Then access the F-AP directly; if not, access the HPN. Terminal nodes with dynamic networking capabilities can form a wireless mesh network Mesh topology, tree topology or star topology under the control of HPN or F-AP through terminal direct connection. Nodes with caching capabilities can be used as branch nodes. Cluster nodes, this method can enable more terminals to access the network and increase the connection density of the network.

步骤S701，获取终端的位置、区域的业务分布。Step S701, acquiring the location of the terminal and service distribution in the area.
步骤S702，将区域中重复请求次数大于业务下发门限值N1的业务请求发送至雾接入节点。Step S702, sending the service requests whose number of repeated requests in the area is greater than the service delivery threshold N1 to the fog access node.
步骤S703，判断该终端是否具备终端直通通信能力。Step S703, judging whether the terminal has the terminal direct communication capability.
如果该终端具备终端直通通信能力，执行步骤S704，判断区域中该终端对应的用户之外的其他用户是否有该业务请求。If the terminal has the terminal direct communication capability, step S704 is executed to determine whether other users in the area other than the user corresponding to the terminal have the service request.
如果区域中其他用户有该业务请求，执行步骤S705，判断该终端与其他终端之间的距离是否小于终端直通模式的距离门限值D1。If other users in the area have the service request, step S705 is executed to determine whether the distance between the terminal and other terminals is smaller than the distance threshold D1 of the terminal direct mode.
如果该终端与其他终端之间的距离小于终端直通模式的距离门限值，执行步骤S706，网络切片的配置方案中的组网方式为终端直通模式。If the distance between the terminal and other terminals is smaller than the distance threshold of the terminal direct mode, step S706 is executed, and the networking mode in the network slicing configuration solution is the terminal direct mode.
如果区域中其他用户没有该业务请求、该终端与其他终端之间的距离大于或等于终端直通模式的距离门限值、或该终端不具备终端直通通信能力，执行步骤S707，判断该用户所在小区雾接入节点是否缓存该用户所请求资源。If other users in the area do not have the service request, the distance between the terminal and other terminals is greater than or equal to the distance threshold of the terminal direct mode, or the terminal does not have the terminal direct communication capability, perform step S707 to determine the cell where the user is located Whether the fog access node caches the resources requested by the user.
如果用户所在小区雾接入节点有缓存该用户所请求资源，执行步骤S708，网络切片的配置方案中的组网方式为用户接入雾接入节点。If the fog access node in the community where the user is located has cached the resources requested by the user, step S708 is executed, and the networking mode in the network slice configuration scheme is that the user accesses the fog access node.

具体的，接入网切片编排器首先通过观察网络中业务分布情况，然后将各种业务重复请求次数大于预设门限值N1的业务下发至网络中的F-AP节点；接入网切片编排器首先判断该终端是否具备终端直通通信能力。如果具备，则进一步判断在该用户所在小区，是否有其他用户拥有该用户请求的业务。如果有，则进一步判断终端与其他终端之间的距离是否小于终端直通模式的距离门限值D1。如果是，则通过终端直通模式便可获取该业务。或者，如果终端不具备终端直通通信能力，或该小区没有其他用户拥有该业务，或拥有该业务的用户无法与该用户进行终端直通通信，则进一步判断，用户所在小区F-AP是否缓存有该用户所请求资源，如果有，则用户采用接入F-AP模式获取业务；如果没有，接入网切片编排器将该业务发送至F-AP中，用户再采用接入F-AP模式获取业务。Specifically, the access network slicing orchestrator first observes the distribution of services in the network, and then sends the services whose repeated requests for various services are greater than the preset threshold value N1 to the F-AP nodes in the network; the access network slicing The orchestrator first judges whether the terminal has the terminal direct communication capability. If so, it is further judged whether there are other users who have the service requested by the user in the cell where the user is located. If so, it is further judged whether the distance between the terminal and other terminals is smaller than the distance threshold D1 of the terminal direct mode. If yes, the service can be obtained through the terminal direct mode. Or, if the terminal does not have the terminal direct communication capability, or there is no other user in the cell that has the service, or the user who owns the service cannot perform terminal direct communication with the user, it is further judged whether the F-AP in the cell where the user is located has cached the service. If the resource requested by the user is available, the user obtains the service by accessing the F-AP mode; if not, the access network slice orchestrator sends the service to the F-AP, and the user then obtains the service by accessing the F-AP mode .
步骤S104中，根据周期性获取的网络中各协议层的参数，判断是否需要对每种网络切片进行调整的具体方法，参见图8，图8为本发明实施例的网络切片调整的流程图，包括以下步骤：In step S104, according to the parameters of each protocol layer in the network obtained periodically, a specific method for judging whether to adjust each network slice is required, see FIG. 8 , which is a flowchart of network slice adjustment according to an embodiment of the present invention. Include the following steps:
步骤S801，根据周期性获取的网络中各协议层的参数，监测业务请求、用户位置和用户移动性。Step S801, monitor service requests, user locations and user mobility according to periodically acquired parameters of each protocol layer in the network.
步骤S802，判断用户请求的业务场景是否发生改变。Step S802, judging whether the service scenario requested by the user has changed.
如果用户请求的业务场景发生改变，执行步骤S803，根据获取的信息感知结果，确定网络切片的种类，确定每种网络切片的配置方案。If the service scenario requested by the user changes, step S803 is executed to determine the type of network slice and the configuration scheme of each network slice according to the obtained information perception result.
如果用户请求的业务场景没有发生改变，执行步骤S804，判断网络切片的关键性能是否超过预设门限值。If the service scenario requested by the user has not changed, step S804 is executed to determine whether the key performance of the network slice exceeds the preset threshold.
如果网络切片的关键性能超过预设门限值，执行步骤S805，使网络切片进行重配置。If the key performance of the network slice exceeds the preset threshold, step S805 is performed to enable the network slice to be reconfigured.
参见图9，图9为本发明实施例的判断用户请求的业务场景是否发生改变的流程图，步骤S802中，更为具体的判断方法包括以下步骤：Referring to FIG. 9, FIG. 9 is a flow chart of judging whether the business scenario requested by the user has changed according to an embodiment of the present invention. In step S802, a more specific judging method includes the following steps:
步骤S901，判断用户是否发起新的业务请求。Step S901, judging whether the user initiates a new service request.
如果用户发起新的业务请求，执行步骤S902，识别新的业务请求的业务类型是否发生改变。If the user initiates a new service request, step S902 is executed to identify whether the service type of the new service request has changed.
如果新的业务请求的业务类型发生改变，执行步骤S903，判断该业务类型所属业务场景是否与已配置的网络切片对应业务场景一致。If the service type of the new service request changes, step S903 is executed to determine whether the service scenario to which the service type belongs is consistent with the configured service scenario corresponding to the network slice.
如果该业务类型所属业务场景与已配置的网络切片对应业务场景不一致，判断用户请求的业务场景发生改变。If the service scenario to which the service type belongs is inconsistent with the configured service scenario corresponding to the network slice, it is determined that the service scenario requested by the user has changed.
如果步骤S901中用户没有发起新的业务请求、步骤S902中新的业务请求的业务类型没有发生改变、或步骤S903中该业务类型所属业务场景与已配置的网络切片对应业务场景一致，判断用户请求的业务场景没有发生改变。If the user does not initiate a new service request in step S901, the service type of the new service request in step S902 has not changed, or the service scenario of the service type in step S903 is consistent with the configured network slicing corresponding service scenario, determine the user request The business scenario has not changed.
需要说明的是，用户在接入网络之后所进行的业务并不是一成不变的，用户会实时根据自己的业务需求发起不同的业务请求。例如，用户当前的业务类型为语音业务，但是在进行语音业务的同时又需要下载视频，那么，用户就需要发起新的业务请求，该新的业务请求为数据业务请求，与之前的语音业务的业务类型不同，也就是用户的业务类型发生了改变。It should be noted that the services performed by users after accessing the network are not static, and users will initiate different service requests in real time according to their own service requirements. For example, if the user's current service type is a voice service, but the user needs to download video while performing the voice service, then the user needs to initiate a new service request, which is a data service request, which is different from the previous voice service. The business type is different, that is, the user's business type has changed.
或or
步骤S904，判断用户位置是否发生变化。Step S904, judging whether the user's location changes.
如果用户位置发生变化，执行步骤S905，判断用户的位置是否超出网络切片的覆盖范围。If the location of the user changes, step S905 is executed to determine whether the location of the user exceeds the coverage of the network slice.
如果用户的位置超出网络切片的覆盖范围，执行步骤S906，判断用户所属区域的业务场景是否改变。If the user's location is beyond the coverage of the network slice, step S906 is executed to determine whether the service scenario of the area to which the user belongs has changed.
如果用户所属区域的业务场景改变，判断用户请求的业务场景发生改变。If the business scenario of the area to which the user belongs changes, it is determined that the business scenario requested by the user has changed.
如果步骤S904中用户位置没有发生变化、步骤S905中用户的位置没有超出网络切片的覆盖范围、或步骤S906中用户所属区域的业务场景没有改变，判断用户请求的业务场景没有发生改变。If the user's location does not change in step S904, the user's location does not exceed the coverage of the network slice in step S905, or the service scenario of the area to which the user belongs does not change in step S906, it is determined that the service scenario requested by the user has not changed.
或or
步骤S907，判断用户的移动性是否发生改变。Step S907, judging whether the mobility of the user changes.
如果用户的移动性发生改变，执行步骤S908，判断用户移动性是否超出网络切片的支持范围。If the mobility of the user changes, step S908 is executed to determine whether the mobility of the user exceeds the support range of the network slice.
如果用户移动性超出网络切片的支持范围，判断用户请求的业务场景发生改变。If the mobility of the user exceeds the support range of the network slice, it is judged that the service scenario requested by the user has changed.
如果步骤S907中用户的移动性没有发生改变、或步骤S908中用户移动性没有超出网络切片的支持范围，判断用户请求的业务场景没有发生改变。If the mobility of the user does not change in step S907, or the mobility of the user does not exceed the range supported by the network slice in step S908, it is determined that the service scenario requested by the user has not changed.
接入网切片编排器通过监测业务请求、用户位置与用户的移动性这三个方面，来判别是否需要更换网络切片类型。在判断用户请求的业务场景发生改变时，接入网切片编排器联合用户、终端、业务与当前网络性能与状况，通过识别用户当前位置、用户移动性、终端性能与业务特征以及对网络的资源需求，为该用户重新调整切片类型，并为新的切片配置无线资源与缓存策略。The access network slice orchestrator judges whether it is necessary to replace the network slice type by monitoring three aspects: service request, user location, and user mobility. When judging that the service scenario requested by the user changes, the access network slice orchestrator combines the user, terminal, service, and current network performance and status to identify the user's current location, user mobility, terminal performance and service characteristics, and network resources. Re-adjust the slice type for this user, and configure wireless resources and cache policies for the new slice.
需要说明的是，业务类型、用户位置、用户的移动性三者中任一元素的变化，均可能导致用户场景的变化，故当切片开始运行后，无线网路切片编排器必须周期性监测这三类数据，并快速做出判决与响应，从而不会影响到用户体验。It should be noted that changes in any of the elements of service type, user location, and user mobility may lead to changes in user scenarios. Therefore, when the slice starts running, the wireless network slice orchestrator must periodically monitor these Three types of data, and quickly make judgments and responses, so as not to affect the user experience.
可选的，本发明实施例的基于信息感知的无线通信组网方法中，判断网络切片的关键性能是否超过预设门限值的步骤，包括：Optionally, in the wireless communication networking method based on information perception in the embodiment of the present invention, the step of judging whether the key performance of the network slice exceeds a preset threshold value includes:
当网络切片为广域无缝覆盖切片时，如果用户数据传输速率小于第一预设速率、或掉话率大于0、或小区切换成功率小于100％，判断网络切片的关键性能超过预设门限值。When the network slice is a wide-area seamless coverage slice, if the user data transmission rate is less than the first preset rate, or the call drop rate is greater than 0, or the cell handover success rate is less than 100%, it is judged that the key performance of the network slice exceeds the preset threshold limit.
如果用户数据传输速率大于或等于第一预设速率、且掉话率等于0、且小区切换成功率为100％，判断网络切片的关键性能没有超过预设门限值。If the user data transmission rate is greater than or equal to the first preset rate, the call drop rate is equal to 0, and the cell handover success rate is 100%, it is determined that the key performance of the network slice does not exceed the preset threshold.
需要说明的是，广域无缝覆盖切片以保证用户的移动性和业务连续性为目标，为用户提供无缝的高速移动业务体验。掉话率是指在移动通信的过程中，通信意外中断的几率，因此在广域无缝覆盖切片中，通信是不能中断的，小区切换成功率为100％，掉话率为0。第一预设速率可以为100兆比特每秒，或者其他根据实际情况设定的值，在此不做限定。It should be noted that the wide-area seamless coverage slice aims to ensure user mobility and service continuity, and provides users with seamless high-speed mobile service experience. The call drop rate refers to the probability of unexpected communication interruption during the mobile communication process. Therefore, in the wide area seamless coverage slice, the communication cannot be interrupted. The cell handover success rate is 100%, and the call drop rate is 0. The first preset rate may be 100 Mbits per second, or other values set according to actual conditions, which are not limited herein.
或or
当网络切片为热点高容量切片时，如果用户数据传输速率小于第二预设速率、或掉话率大于0、或峰值速率小于第三预设速率，判断网络切片的关键性能超过预设门限值。When the network slice is a hotspot high-capacity slice, if the user data transmission rate is less than the second preset rate, or the call drop rate is greater than 0, or the peak rate is less than the third preset rate, it is judged that the key performance of the network slice exceeds the preset threshold value.
如果用户数据传输速率大于或等于第二预设速率、且掉话率等于0、且峰值速率大于或等于第三预设速率，判断网络切片的关键性能没有超过预设门限值。If the user data transmission rate is greater than or equal to the second preset rate, the call drop rate is equal to 0, and the peak rate is greater than or equal to the third preset rate, it is determined that the key performance of the network slice does not exceed the preset threshold.
需要说明的是，热点高容量切片主要面向局部热点区域，为用户提高极高的数据传输速率，因此，对数据传输速率的要求是极高的，第二预设速率可以为1吉比特每秒，第三预设速率可以为10吉比特每秒，当然，第二预设速率和第三预设速率的值也可以根据实际业务需求设定，在此不做限定。另外，热点高容量切片也是要求通信是不能中断的，因此掉话率为0。It should be noted that hotspot high-capacity slicing is mainly for local hotspot areas to increase the extremely high data transmission rate for users. Therefore, the requirement for data transmission rate is extremely high, and the second preset rate can be 1 gigabit per second , the third preset rate may be 10 gigabits per second. Of course, the values of the second preset rate and the third preset rate may also be set according to actual service requirements, which are not limited here. In addition, hotspot high-capacity slicing also requires that communication cannot be interrupted, so the call drop rate is 0.
或or
当网络切片为低功耗大连接切片时，如果终端功耗大于功耗预设门限值、或掉话率大于0、或网络连接数密度小于连接密度预设阈值，判断网络切片的关键性能超过预设门限值。When network slicing is low-power consumption and large-connection slicing, if the terminal power consumption is greater than the preset power consumption threshold, or the call drop rate is greater than 0, or the network connection density is lower than the connection density preset threshold, determine the key performance of the network slice exceeds the preset threshold.
如果终端功耗小于或等于功耗预设门限值、且掉话率等于0、且网络连接数密度大于或等于连接密度预设阈值，判断网络切片的关键性能没有超过预设门限值。If the power consumption of the terminal is less than or equal to the preset threshold value of power consumption, and the call drop rate is equal to 0, and the density of network connections is greater than or equal to the preset threshold value of connection density, it is judged that the key performance of the network slice does not exceed the preset threshold value.
需要说明的是，低功耗大连接切片主要满足100万每平方公里连接数密度，同时保障终端超低功耗和超低成本，因此，要求终端满足低功耗，使得终端至少工作10年以上。网络连接密度大于或等于1百万每平方公里，网络不能发生中断，即掉话率为0。It should be noted that the low-power large connection slice mainly meets the density of 1 million connections per square kilometer, and at the same time guarantees ultra-low power consumption and ultra-low cost of the terminal. Therefore, the terminal is required to meet low power consumption, so that the terminal can work for at least 10 years . The network connection density is greater than or equal to 1 million per square kilometer, and the network cannot be interrupted, that is, the call drop rate is 0.

当网络切片为低时延高可靠切片时，如果端到端时延大于第一时延阈值、或空口时延大于第二时延阈值、或传输可靠率小于可靠率阈值，判断网络切片的关键性能超过预设门限值；When the network slice is a low-latency high-reliability slice, if the end-to-end delay is greater than the first delay threshold, or the air interface delay is greater than the second delay threshold, or the transmission reliability is lower than the reliability threshold, the key to judging the network slice is The performance exceeds the preset threshold value;
如果端到端时延小于或等于第一时延阈值、且空口时延小于或等于第二时延阈值、且传输可靠率大于或等于可靠率阈值，判断网络切片的关键性能没有超过预设门限值。If the end-to-end delay is less than or equal to the first delay threshold, and the air interface delay is less than or equal to the second delay threshold, and the transmission reliability rate is greater than or equal to the reliability rate threshold, it is judged that the key performance of the network slice does not exceed the preset threshold limit.
需要说明的是，低时延高可靠切片对时延和可靠性要求极高的应用提供保障，因此，端到端的时延要小于第一时延阈值10毫秒，其中，端到端指低时延高可靠切片中的任意两个节点，可以是网络到终端，也可以是终端A到终端B。空口时延小于第二时延阈值1毫秒，传输可靠性大于可靠率阈值99.99999％。当然，该第一时延阈值、第二时延阈值和可靠率阈值不是上述确定的值，根据实际需求进行设定，在此不做限定。It should be noted that low-latency and high-reliability slices provide protection for applications with extremely high latency and reliability requirements. Therefore, the end-to-end latency should be less than the first latency threshold of 10 milliseconds. Any two nodes in the extended reliable slice can be from the network to the terminal, or from terminal A to terminal B. The air interface delay is less than the second delay threshold of 1 millisecond, and the transmission reliability is greater than the reliability threshold of 99.99999%. Of course, the first delay threshold, the second delay threshold, and the reliability threshold are not the above-mentioned determined values, and are set according to actual requirements, and are not limited here.
可选的，本发明实施例的基于信息感知的无线通信组网方法中，使网络切片进行重配置的步骤，包括：Optionally, in the information-aware-based wireless communication networking method in the embodiment of the present invention, the step of reconfiguring the network slice includes:
当前网络切片根据接入网切片编辑器发送的资源调整预警和建议方案，向当前网络中运行的其他网络切片顺序发送相应的干扰水平与时延水平。The current network slice sends the corresponding interference level and delay level sequentially to other network slices running in the current network according to the resource adjustment warning and suggestion plan sent by the access network slice editor.
当前网络切片接收其他网络切片针对干扰水平与时延水平、反馈的调整后的可用的无线资源与缓存配置。The current network slice receives the adjusted available radio resources and cache configurations from other network slices for the interference level and delay level and feedback.
当前网络切片根据调整后的可用的无线资源与缓存配置，对相应的组网方式、无线资源与缓存配置进行调整，并将调整信息发送给接入网切片编排器。The current network slice adjusts the corresponding networking mode, wireless resource and cache configuration according to the adjusted available wireless resources and cache configuration, and sends the adjustment information to the access network slice orchestrator.
针对不同切片类型，无线网络编排器给出的调整方案也不同，针对四种典型切片种类，接入网切片编排器根据监测切片的主关键性能，给出具体的切片重配置方案。For different slice types, the wireless network orchestrator provides different adjustment schemes. For the four typical slice types, the access network slice orchestrator provides specific slice reconfiguration schemes according to the main key performance of the monitored slices.
针对广域无缝覆盖切片，主关键性能分别为用户体验速率、掉话率、小区切换成功率。若接入网切片编排器监测到用户的体验速率低于第一预设速率100兆比特每秒，可以通过调整HPN或终端的发射功率或为用户重新分配与别的切片干扰小的频谱资源来提高业务的传输速率。若接入网切片编排器检测到用户的掉话率高于预定门限值0或小区切换成功率小于100％，则可以通过增加HPN的天线数目或为HPN增加分布式天线设备功能，提升HPN的网络覆盖范围今儿降低用户的掉话率和小区切换失败率。For wide-area seamless coverage slices, the main key performances are user experience rate, call drop rate, and cell handover success rate. If the access network slice orchestrator detects that the user's experience rate is lower than the first preset rate of 100 Mbits per second, it can adjust the transmission power of the HPN or the terminal or reallocate spectrum resources with little interference with other slices for the user. Improve the transmission rate of the business. If the access network slice orchestrator detects that the user’s call drop rate is higher than the predetermined threshold value 0 or the cell handover success rate is less than 100%, it can increase the number of antennas of the HPN or add the function of distributed antenna equipment to the HPN to improve the HPN Wider network coverage reduces the user's call drop rate and cell handover failure rate.
针对热点高容量切片，主关键性能分别为用户体验速率、峰值速率和网络流量密度。若接入网切片编排器检测到该热点区域没有办法为用户提供1吉比特每秒的体验速率，网络的流量密度没有达到100万/平方公里，则可以通过提高RRH的部署密度提高网络的吞吐量，同时根据网络中切片干扰分布图，调整该切片的频谱资源的位置和带宽来降低切片的干扰水平今儿提高用户的体验速率以及峰值数据速率。For hotspot high-capacity slicing, the main key performances are user experience rate, peak rate, and network traffic density. If the access network slice orchestrator detects that the hotspot area cannot provide users with an experience rate of 1 Gbit/s, and the traffic density of the network does not reach 1 million/square kilometer, the network throughput can be improved by increasing the deployment density of RRH At the same time, according to the slice interference distribution map in the network, adjust the position and bandwidth of the spectrum resource of the slice to reduce the interference level of the slice and improve the user experience rate and peak data rate.
针对低功耗大连接切片，主关键性能分别为网络连接数密度以及终端功耗值。若接入网切片编排器通过获取网络QoS感知结果发现网络针对该类型终端的连接数密度没有达到连接密度预设阈值100万/平方公里，进一步判断是否因为网络覆盖范围而使得网络连接数密度没有达到预定门限值，如果是，则可以通过增加HPN的天线数目或为HPN增加分布式天线设备功能来增加网络的覆盖范围；否则，可以调低该场景下终端直通距离门限值D1，使得更多的终端节点能够通过终端直通方式进行动态组网，接入网路，提升网络连接数密度。若接入网切片编排器监测终端的功耗增加，则可以降低终端的发射功率与接收功率使得终端功耗满足网络预设门限值，进一步，使得终端的使用寿命超过十年。For low-power large-connection slicing, the main key performances are network connection density and terminal power consumption. If the access network slice orchestrator obtains the network QoS perception results and finds that the network connection density for this type of terminal does not reach the connection density preset threshold of 1 million per square kilometer, further judge whether the network connection density is lower due to the network coverage. Reach the predetermined threshold, if yes, increase the coverage of the network by increasing the number of antennas of the HPN or adding the function of distributed antenna equipment for the HPN; otherwise, the threshold value D1 of the terminal direct distance in this scenario can be lowered, so that More terminal nodes can be dynamically networked and connected to the network through terminal direct access, increasing the density of network connections. If the access network slice orchestrator monitors the increase in power consumption of the terminal, it can reduce the transmit power and receive power of the terminal so that the power consumption of the terminal meets the preset threshold value of the network, and further, the service life of the terminal exceeds ten years.
针对低时延高可靠切片，主关键性能分别为业务端到端时延、空口时延、传输可靠性接入网切片编排器若监测到切片端到端时延高于预设门限值，则可以调低该场景下终端直通距离门限值D1，使得用户能够更大的几率通过终端直通模式获取业务，可进一步降低传输时延；或者，用户的控制面接入覆盖面积大的HPN，将用户请求业务下发至离用户最近的F-AP，进一步，数据面接入该F-AP获取业务，实现控制与传输的分离，降低用户的移动性和转发节点过多对时延带来的影响。若接入网切片编排器检测到业务可靠性没有达到网络预设门限值，则通过获取网络QoS感知功能中的切片干扰分布图以及用户的移动速率，调整该切片的频带资源从而降低对该切片的干扰水平，提升业务传输可靠性；针对移动性，可以让用户的控制面接入HPN，降低用户频繁的小区切换带来的影响。For low-latency and high-reliability slices, the main key performances are service end-to-end delay, air interface delay, and transmission reliability. If the access network slice orchestrator detects that the slice end-to-end delay is higher than the preset threshold value, In this scenario, the terminal direct distance threshold value D1 can be lowered, so that users can obtain services through the terminal direct mode with a greater probability, which can further reduce the transmission delay; The user requests the service to be delivered to the F-AP closest to the user, and further, the data plane accesses the F-AP to obtain the service, realizes the separation of control and transmission, and reduces the impact of user mobility and delay caused by too many forwarding nodes . If the access network slice orchestrator detects that the service reliability has not reached the network preset threshold value, it will adjust the frequency band resources of the slice by obtaining the slice interference distribution map in the network QoS perception function and the user's mobile rate to reduce the The interference level of the slice improves the reliability of service transmission; for mobility, the control plane of the user can be connected to the HPN, reducing the impact of frequent cell switching of the user.
