技术领域technical field
本公开涉及通信领域，尤其涉及网络切片配置方法及装置、无线接入网RAN节点和终端。The present disclosure relates to the communication field, and in particular to a network slice configuration method and device, a radio access network RAN node and a terminal.
背景技术Background technique
新一代通信系统引入网络切片(network slicing)技术，该技术允许将网络，核心网(Core Network，CN)和无线接入网(Radio Access Network，RAN)划分为多个切片(slice)。不同的业务在不同的slice里传输，互相不干扰。各个slice的计费策略，安全策略，服务质量策略等都可能不同。The new generation communication system introduces a network slicing (network slicing) technology, which allows a network, a core network (Core Network, CN) and a radio access network (Radio Access Network, RAN) to be divided into multiple slices (slices). Different services are transmitted in different slices without interfering with each other. The billing policy, security policy, and service quality policy of each slice may be different.
相关技术中，CN slice与RAN slice还是一一映射关系，但是CN slice的更新域在一个位置区域，在一个位置区域的CN slices是可能非常多的，这也就意味着一个RAN节点能支持的CN slice切片数目要非常多。如果要做RAN slice与CN slice间的一一映射，一个RAN节点由于其有限的无线资源及处理能力，是无法支持的。这就会导致很多CN slices的RAN隔离度性能因不同RAN节点而差异性较大。In related technologies, there is still a one-to-one mapping relationship between CN slices and RAN slices, but the update domain of CN slices is in a location area, and there may be a lot of CN slices in a location area, which means that a RAN node can support The number of CN slice slices is very large. If one-to-one mapping between RAN slices and CN slices is required, a RAN node cannot support it due to its limited wireless resources and processing capabilities. This will cause the RAN isolation performance of many CN slices to vary greatly due to different RAN nodes.

That is, the list of cell identities of all cells covered by the RAN slice area, for example as shown in FIG. 2A , includes cell identities of cell 1 , cell 2 and cell 3 .
所述终端所在小区支持的RAN切片标识列表，是所述RAN切片区域中所有RAN切片区域的区域标识的列表，例如图2B所示，包括切片区域A、切片区域B和切片区域C的区域标识的列表。The RAN slice identification list supported by the cell where the terminal is located is a list of area identifications of all RAN slice areas in the RAN slice area, for example, as shown in Figure 2B, including the area identifications of slice area A, slice area B, and slice area C list of.
本公开实施例中，为每个小区预设了默认RAN切片区域，例如图2C所示，所述默认RAN切片区域的物理覆盖面积最大。该默认RAN切片区域的资源为小区公共资源，所有不属于某个特定切片区域的输出均在默认RAN切片区域上传输。预先为该默认RAN切片区域配置了切片区域码，用于识别所述默认RAN切片区域。而默认RAN区域无需区域标识，只需要通过RAN切片区域码即可识别。In the embodiment of the present disclosure, a default RAN slice area is preset for each cell. For example, as shown in FIG. 2C , the default RAN slice area has the largest physical coverage area. The resources of the default RAN slice area are common resources of the cell, and all outputs that do not belong to a specific slice area are transmitted on the default RAN slice area. A slice area code is pre-configured for the default RAN slice area to identify the default RAN slice area.

本步骤中，可选地，所述RAN节点可以通过系统消息广播所述基本切片配置信息到终端。In this step, optionally, the RAN node may broadcast the basic slice configuration information to the terminal through a system message.
在步骤102中，根据所述网络切片选择辅助信息，发送目标消息到所述终端，以使所述终端根据所述目标消息，在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In step 102, according to the network slice selection assistance information, a target message is sent to the terminal, so that the terminal selects multiple candidate RANs corresponding to each supported core network slice according to the target message The target RAN slice is determined in the slice.
本步骤中，所述终端会根据所述基本切片配置信息上报网络切片选择辅助信息到所述RAN节点。所述网络切片选择辅助信息是用于帮助所述终端进行RAN和CN切片选择的信息，可以包括切片或服务类型信息，或其他与进行切片选择相关的信息。In this step, the terminal reports network slice selection auxiliary information to the RAN node according to the basic slice configuration information. The network slice selection auxiliary information is information used to help the terminal select RAN and CN slices, and may include slice or service type information, or other information related to slice selection.
可选地，所述RAN节点获取所述网络切片选择辅助信息的过程，如图3所示，图3是根据图1所示实施例的基础上示出的另一种网络切片配置的流程图，可以包括以下步骤：Optionally, the process for the RAN node to obtain the auxiliary information for network slice selection is shown in FIG. 3 , which is a flowchart of another network slice configuration shown on the basis of the embodiment shown in FIG. 1 , can include the following steps:

本步骤中，所述终端会在刚接入网络时，通过所述默认RAN切片发送连接建立请求，请求与RAN节点建立连接。所述RAN节点按照相关技术接收所述连接建立请求即可。In this step, when the terminal first accesses the network, it sends a connection establishment request through the default RAN slice, requesting to establish a connection with the RAN node. The RAN node only needs to receive the connection establishment request according to related technologies.
在步骤102-2中，根据所述连接建立请求建立与所述终端的连接后，发送连接建立消息到所述终端。In step 102-2, after the connection with the terminal is established according to the connection establishment request, a connection establishment message is sent to the terminal.

本步骤中，所述终端在接收到所述连接建立消息后，就会获取所述终端预设配置的用于进行网络切片选择的网络切片选择辅助信息。所述网络切片选择辅助信息可以是由网络预先配置在所述终端中的，例如每个公共陆地移动网络(Public Land MobileNetwork，PLMN)分别进行配置，且可以通过空中激活的方式进行更新。或者所述网络切片选择辅助信息是由终端厂商在终端出厂时写入终端的。In this step, after receiving the connection establishment message, the terminal will obtain the network slice selection auxiliary information preset by the terminal for network slice selection. The network slice selection auxiliary information may be pre-configured in the terminal by the network, for example, each Public Land Mobile Network (Public Land Mobile Network, PLMN) is configured separately, and may be updated through over-the-air activation. Alternatively, the network slice selection auxiliary information is written into the terminal by the terminal manufacturer when the terminal leaves the factory.
所述终端在获取所述网络切片选择辅助信息后，发送携带初始NAS消息的连接建立完成消息到所述RAN节点，其中，所述初始NAS消息和所述连接建立完成消息中携带所述网络切片选择辅助信息。所述初始NAS消息即所述终端在初始接入网络时，发送给所述RAN节点的NAS消息。After acquiring the network slice selection assistance information, the terminal sends a connection establishment complete message carrying an initial NAS message to the RAN node, wherein the initial NAS message and the connection establishment complete message carry the network slice Select Secondary information. The initial NAS message is the NAS message sent to the RAN node when the terminal initially accesses the network.
本步骤中，所述RAN节点按照相关技术在接收到所述终端上报的连接建立完成消息后，根据所述网络切片选择辅助信息，按照相关技术确定与所述终端匹配的目标公共控制网络功能。公共控制网络功能可以是认证功能，移动性管理功能等。In this step, the RAN node selects auxiliary information according to the network slice after receiving the connection establishment completion message reported by the terminal according to related technologies, and determines a target public control network function matching the terminal according to related technologies. The common control network functions may be authentication functions, mobility management functions, etc.
进一步地，所述目标消息中至少携带目标切片配置信息，所述目标切片配置信息至少包括终端所支持的核心网CN切片与RAN切片之间的映射关系。且所述目标切片配置信息还包括以下至少一项：终端所属的RAN切片区域；周期性RAN切片配置更新定时器；其中，所述RAN切片区域通过RAN切片区域码表示或通过小区标识列表表示。Further, the target message at least carries target slice configuration information, and the target slice configuration information includes at least a mapping relationship between CN slices and RAN slices supported by the terminal. And the target slice configuration information further includes at least one of the following: RAN slice area to which the terminal belongs; periodic RAN slice configuration update timer; wherein, the RAN slice area is indicated by a RAN slice area code or by a cell identification list.
本公开实施例中，所述RAN节点需要将所述初始NAS消息到所述目标公共控制网络功能，以使所述目标公共控制网络功能按照相关技术，根据所述初始NAS消息确定所述授权NAS消息。其中，所述授权NAS消息包括授权的网络切片选择辅助信息和临时标识，在该临时标识有效期内，终端可以在随后接入网络时，将临时标识提供给RAN节点，例如基站，RAN节点就会将NAS消息发送给所述目标公共控制网络功能。In the embodiment of the present disclosure, the RAN node needs to send the initial NAS message to the target public control network function, so that the target public control network function can determine the authorized NAS according to the initial NAS message according to related technologies information. Wherein, the authorized NAS message includes authorized network slice selection auxiliary information and a temporary identifier. During the validity period of the temporary identifier, the terminal may provide the temporary identifier to the RAN node, such as a base station, when subsequently accessing the network, and the RAN node will Sending a NAS message to said target common control network function.
所述终端在接收到所述目标公共控制网络功能返回的授权非接入层NAS消息后，发送目标消息到所述终端。可选地，所述目标消息为无线资源控制RRC连接重配消息。所述目标切片配置信息可以作为RRC的网络切片选择辅助信息的一部分携带在所述目标消息中，或者作为单独的信息携带在所述目标消息中。After receiving the authorized non-access stratum NAS message returned by the target public control network function, the terminal sends the target message to the terminal. Optionally, the target message is a radio resource control RRC connection reconfiguration message. The target slice configuration information may be carried in the target message as part of RRC network slice selection assistance information, or carried in the target message as separate information.
本公开实施例中，所述核心网CN切片与RAN切片之间的映射关系包括：In the embodiment of the present disclosure, the mapping relationship between the core network CN slice and the RAN slice includes:
每个CN切片所对应的一个或多个RAN切片；One or more RAN slices corresponding to each CN slice;
其中，若一个CN切片对应于多个RAN切片，每个RAN切片对应于一个优先级，所述优先级可以按照RAN切片标识列表中各个RAN切片标识在列表中的顺序从高到低或从低到高表示，或用于指示每个RAN切片的优先级，CN切片按照所述优先级由高到底的顺序映射到RAN切片上。Wherein, if one CN slice corresponds to multiple RAN slices, each RAN slice corresponds to a priority, and the priority can be from high to low or from low to low according to the order of each RAN slice ID in the RAN slice ID list in the list to high, or used to indicate the priority of each RAN slice, and the CN slices are mapped to the RAN slices in the order of priority from high to low.
一个CN切片可以对应于一个或多个RAN切片，每个RAN切片对应于一个优先级，所述优先级可以按照RAN切片标识列表中各个RAN切片标识在列表中的顺序从高到低或从低到高表示。即按照所述基本切片配置信息中的所述RAN切片标识列表所包括的各个RAN切片标识在该列表中的顺序，从高到低或从低到高来表示。A CN slice can correspond to one or more RAN slices, each RAN slice corresponds to a priority, and the priority can be from high to low or from low to low according to the order of each RAN slice ID in the RAN slice ID list in the list to high representation. That is, according to the order of each RAN slice identifier included in the RAN slice identifier list in the basic slice configuration information in the list, it is expressed from high to low or from low to high.
或者，所述优先级还可以用于指示每个RAN切片的优先级。Alternatively, the priority may also be used to indicate the priority of each RAN slice.
终端优先选择将CN切片映射到最高级别的优先级对应的RAN切片上，当没有该RAN切片覆盖时，则回退到次一级优先级的RAN切片上，依次类推，当最低一级别的RAN切片也没有时，则回退到默认RAN切片。RAN切片的优先级越低，则物理隔离度等级越低，所占用的公共资源越多，例如与其他的RAN切片共用载波或物理信道，服务的CN切片越多，相应地CN切片间干扰也越严重，覆盖的地理面积也越大。相反，优先级越高，其服务的CN切片越少，CN切片间干扰也越小，覆盖的地理面积也越小，所占用的公共资源越小，例如使用单独的物理信道。The terminal preferentially chooses to map the CN slice to the RAN slice corresponding to the highest level of priority. When there is no coverage of the RAN slice, it will fall back to the RAN slice of the next level of priority, and so on. When the lowest level of RAN If there is no slice, fall back to the default RAN slice. The lower the priority of the RAN slice, the lower the physical isolation level, and the more common resources it occupies. For example, if it shares a carrier or physical channel with other RAN slices, the more CN slices it serves, the correspondingly the interference between CN slices also increases. The more serious it is, the larger the geographical area covered. On the contrary, the higher the priority, the fewer CN slices it serves, the smaller the interference between CN slices, the smaller the geographical area covered, and the smaller the public resources occupied, such as using a separate physical channel.
一个RAN节点可以只支持几个大级别的RAN切片，也可以同时再支持一些小级别的RAN切片。这取决于该节点的能力，如果RAN节点有较多的无线资源/处理能力，或当前负荷不重，就可以支持多个小级别的RAN切片。RAN节点根据小级别切片的增减，动态地调整大级别切片与小级别切片的资源池大小。A RAN node can only support several large-level RAN slices, or it can also support some small-level RAN slices at the same time. It depends on the capability of the node. If the RAN node has more radio resources/processing capabilities, or the current load is not heavy, it can support multiple small-level RAN slices. The RAN node dynamically adjusts the size of resource pools for large-level slices and small-level slices according to the increase or decrease of small-level slices.
通过上述多个RAN切片分级的好处是，当RAN节点无法提供最优的隔离方案时，可以回退到次优的隔离方案，而不是完全没有隔离，从而可以提供一定的服务质量保障。The advantage of grading through the above multiple RAN slices is that when the RAN node cannot provide an optimal isolation solution, it can fall back to a suboptimal isolation solution instead of no isolation at all, thereby providing a certain quality of service guarantee.
本公开实施例中，RAN节点在发送目标信息到终端后，可以进一步发送终端连接释放消息到终端，以使终端按照相关技术回到idle状态或inactive状态。终端此时会保存授权的网络切片选择辅助信息和所述目标切片配置信息。In the embodiment of the present disclosure, after sending the target information to the terminal, the RAN node may further send a terminal connection release message to the terminal, so that the terminal returns to an idle state or an inactive state according to related technologies. At this time, the terminal will save the authorized network slice selection auxiliary information and the target slice configuration information.
上述实施例中，可以看出CN切片和RAN切片不再是一一对应的，每个核心网切片可以对应多个备选RAN切片，也就说将多个CN切片映射到一个RAN切片，使得一个RAN节点可以支持大量的CN切片，从而节省了RAN节点的无线资源，且提高了RAN节点的处理能力。In the above embodiment, it can be seen that CN slices and RAN slices are no longer in one-to-one correspondence, each core network slice can correspond to multiple candidate RAN slices, that is to say, multiple CN slices are mapped to one RAN slice, so that A RAN node can support a large number of CN slices, thereby saving radio resources of the RAN node and improving the processing capability of the RAN node.
本公开实施例中，所述RAN节点可以在接收到RAN切片区域更新请求或位置更新请求后，发送携带所述终端当前所在RAN切片区域对应的所述目标切片区域配置信息的RAN切片区域更新指令到所述终端，以使所述终端根据所述RAN切片区域更新指令，重新在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In the embodiment of the present disclosure, after receiving the RAN slice area update request or the location update request, the RAN node may send a RAN slice area update instruction carrying the configuration information of the target slice area corresponding to the RAN slice area where the terminal is currently located to the terminal, so that the terminal re-determines a target RAN slice in multiple candidate RAN slices corresponding to each supported core network slice according to the RAN slice area update instruction.
如图4所示，图4是根据图1所示实施例的基础上示出的另一种网络切片配置的流程图，在完成步骤102之后，还可以包括以下步骤：As shown in FIG. 4, FIG. 4 is a flowchart of another network slicing configuration shown on the basis of the embodiment shown in FIG. 1. After step 102 is completed, the following steps may also be included:
在步骤103中，在接收到所述终端发送的RAN切片区域更新请求后，发送携带所述终端当前所在RAN切片区域对应的所述目标切片区域配置信息的RAN切片区域更新指令到所述终端。In step 103, after receiving the RAN slice area update request sent by the terminal, send a RAN slice area update instruction carrying the target slice area configuration information corresponding to the RAN slice area where the terminal is currently located to the terminal.
本步骤中，所述RAN节点在接收到所述终端发送的所述RAN切片区域更新请求后，自动发送所述RAN切片区域更新指令到终端。所述RAN切片区域更新指令中携带了所述终端当前所在RAN切片区域对应的所述目标切片区域配置信息。这样，所述终端就可以根据当前接收的所述目标切片区域配置信息重新在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In this step, the RAN node automatically sends the RAN slice area update instruction to the terminal after receiving the RAN slice area update request sent by the terminal. The RAN slice area update instruction carries the configuration information of the target slice area corresponding to the RAN slice area where the terminal is currently located. In this way, the terminal can re-determine the target RAN slice among multiple candidate RAN slices corresponding to each supported core network slice according to the currently received configuration information of the target slice area.
上述实施例中，RAN节点可以在接收到RAN切片区域更新请求后，自动发送所述RAN切片区域更新指令到终端。从而确保可以完成终端的RAN切片区域的更新过程。In the above embodiment, the RAN node may automatically send the RAN slice area update instruction to the terminal after receiving the RAN slice area update request. Therefore, it is ensured that the update process of the RAN slice area of the terminal can be completed.
如图5所示，图5是根据图1所示实施例的基础上示出的另一种网络切片配置的流程图，在完成步骤102之后，还可以包括以下步骤：As shown in FIG. 5, FIG. 5 is a flowchart of another network slicing configuration shown on the basis of the embodiment shown in FIG. 1. After step 102 is completed, the following steps may also be included:
在步骤104中，在接收到所述终端上报的位置更新请求后，发送携带所述终端当前所在RAN切片区域对应的所述目标切片区域配置信息的RAN切片区域更新指令到所述终端。In step 104, after receiving the location update request reported by the terminal, send a RAN slice area update instruction carrying the target slice area configuration information corresponding to the RAN slice area where the terminal is currently located to the terminal.
本步骤中，所述RAN节点一旦接收到所述终端发送的位置更新请求，则自动认为所述终端还同时请求进行RAN切片区域更新。即此时，RAN切片区域的面积与终端的跟踪区域面积相同，RAN切片区域复用跟踪区域码，RAN节点没必要单独指示RAN切片区域给终端，且无需使用上述更新定时器，可以直接使用位置更新定时器。终端在发送区域位置更新请求的RRC连接建立完成消息中携带网络切片选择辅助信息，RAN节点自动返回携带所述终端当前所在RAN切片区域对应的所述目标切片区域配置信息的RAN切片区域更新指令到所述终端。这样，所述终端就可以根据当前接收的所述目标切片区域配置信息重新在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In this step, once the RAN node receives the location update request sent by the terminal, it automatically considers that the terminal also requests RAN slice area update at the same time. That is, at this time, the area of the RAN slice area is the same as the area of the tracking area of the terminal, and the RAN slice area multiplexes the tracking area code. The RAN node does not need to separately indicate the RAN slice area to the terminal, and does not need to use the above update timer, and can directly use the location Update timer. The terminal carries network slice selection auxiliary information in the RRC connection establishment completion message sending the area location update request, and the RAN node automatically returns the RAN slice area update command carrying the target slice area configuration information corresponding to the RAN slice area where the terminal is currently located to the terminal. In this way, the terminal can re-determine the target RAN slice among multiple candidate RAN slices corresponding to each supported core network slice according to the currently received configuration information of the target slice area.
上述实施例中，RAN节点可以在接收到位置更新请求后，自动发送所述RAN切片区域更新指令到终端。从而确保可以完成终端的RAN切片区域的更新过程。In the above embodiment, the RAN node may automatically send the RAN slice area update instruction to the terminal after receiving the location update request. Therefore, it is ensured that the update process of the RAN slice area of the terminal can be completed.
可选地，在上述实施例中，终端还可以同时上报自身记录的之前配置的目标切片配置信息，即所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片，以便RAN节点参考之前配置的切片配置信息来进行新的目标切片配置信息的确定，加快切片区域更新过程，节省RAN节点资源。Optionally, in the above embodiment, the terminal can also report the previously configured target slice configuration information recorded by itself at the same time, that is, determine the target RAN slice among multiple candidate RAN slices corresponding to each supported core network slice, In order for the RAN node to refer to the previously configured slice configuration information to determine new target slice configuration information, speed up the slice area update process, and save RAN node resources.
应当注意地是，本公开实施例中，终端在离开当前所对应的RAN切片区域所覆盖的地理位置范围时，之前终端已经完成的切片配置无效，除非终端再次回到该RAN切片区域。但是，如果这期间终端需要接入小区时，终端通过默认RAN切片区域接入小区，并在连接建立完成消息(或连接恢复完成消息、连接重建完成消息、RAN位置区域更新请求)中携带请求更新切片配置信息。可选地，终端可以同时上报之前记录的切片配置信息。RAN节点自动发送所述RAN切片区域更新指令到终端。从而确保可以完成终端的RAN切片区域的更新过程。It should be noted that in the embodiments of the present disclosure, when the terminal leaves the geographic location covered by the current corresponding RAN slice area, the slice configuration completed by the terminal before is invalid unless the terminal returns to the RAN slice area again. However, if the terminal needs to access the cell during this period, the terminal accesses the cell through the default RAN slice area, and carries the request update in the connection establishment complete message (or connection recovery complete message, connection reestablishment complete message, RAN location area update request) Slice configuration information. Optionally, the terminal may simultaneously report the previously recorded slice configuration information. The RAN node automatically sends the RAN slice area update instruction to the terminal. Therefore, it is ensured that the update process of the RAN slice area of the terminal can be completed.
本公开实施例提供的网络切片配置方法还可以用于终端，例如，智能手机、平板电脑、个人数字助理(Personal Digital Assistant，PDA)等。如图6所示，图6是根据一示例性实施例示出的另一种网络切片配置方法，包括以下步骤：The network slicing configuration method provided by the embodiments of the present disclosure may also be applied to terminals, for example, smart phones, tablet computers, personal digital assistants (Personal Digital Assistant, PDA) and the like. As shown in FIG. 6, FIG. 6 is another network slice configuration method shown according to an exemplary embodiment, including the following steps:
在步骤201中，在接收到RAN节点发送的基本切片配置信息后，获取所述终端预先配置的用于进行网络切片选择的网络切片选择辅助信息。In step 201, after receiving the basic slice configuration information sent by the RAN node, acquire network slice selection auxiliary information pre-configured by the terminal for network slice selection.
其中，所述网络切片选择辅助信息是用于帮助所述终端进行网络切片选择的信息，可以包括切片或服务类型信息，或其他与进行切片选择相关的信息。所述网络切片选择辅助信息可以是由网络预先配置在所述终端中的，例如每个公共陆地移动网络(PublicLand Mobile Network，PLMN)分别进行配置，且可以通过空中激活的方式进行更新。或者所述网络切片选择辅助信息是由终端厂商在终端出厂时写入终端的。本步骤中，所述终端可以按照相关技术先接收RAN节点通过系统消息广播的基本切片配置信息。所述基本切片配置信息包括：Wherein, the network slice selection auxiliary information is information used to help the terminal select a network slice, and may include slice or service type information, or other information related to slice selection. The network slice selection auxiliary information may be pre-configured in the terminal by the network, for example, each Public Land Mobile Network (PublicLand Mobile Network, PLMN) is configured separately, and may be updated through over-the-air activation. Alternatively, the network slice selection auxiliary information is written into the terminal by the terminal manufacturer when the terminal leaves the factory. In this step, the terminal may first receive the basic slice configuration information broadcast by the RAN node through a system message according to related technologies. The basic slice configuration information includes:
所述终端所属的RAN切片区域，所述终端所在小区支持的RAN切片标识列表和RAN切片的无线资源配置信息；The RAN slice area to which the terminal belongs, the RAN slice identification list supported by the cell where the terminal is located and the radio resource configuration information of the RAN slice;
其中，所述RAN切片区域通过RAN切片区域码表示或通过小区标识列表表示。Wherein, the RAN slice area is represented by a RAN slice area code or a cell identification list.
所述终端在初始接入网络时，可以先通过预设的默认RAN切片发送连接建立请求到RAN节点，接收所述RAN节点根据所述连接建立请求建立与所述终端的连接后发送到所述终端的连接建立消息后，按照相关技术获取所述网络切片选择辅助信息。When the terminal initially accesses the network, it may first send a connection establishment request to the RAN node through a preset default RAN slice, and after receiving the connection establishment request, the RAN node establishes a connection with the terminal and sends it to the After the connection establishment message of the terminal, the network slice selection auxiliary information is obtained according to related technologies.
本公开实施例中，为每个小区预设了默认RAN切片区域，例如图2C所示，所述默认RAN切片区域的物理覆盖面积最大。该默认RAN切片区域的资源为小区公共资源，所有不属于某个特定切片区域的输出均在默认RAN切片区域上传输。预先为该默认RAN切片区域配置了切片区域码，用于识别所述默认RAN切片区域。而默认RAN区域无需区域标识，只需要通过RAN切片区域码即可识别。In the embodiment of the present disclosure, a default RAN slice area is preset for each cell. For example, as shown in FIG. 2C , the default RAN slice area has the largest physical coverage area. The resources of the default RAN slice area are common resources of the cell, and all outputs that do not belong to a specific slice area are transmitted on the default RAN slice area. A slice area code is pre-configured for the default RAN slice area to identify the default RAN slice area. The default RAN area does not need an area identifier, and can be identified only by the RAN slice area code.
在接收到所述连接建立消息后，按照上述方式获取所述终端预先配置的所述网络切片选择辅助信息即可。After receiving the connection establishment message, it is sufficient to obtain the auxiliary network slice selection information pre-configured by the terminal in the above manner.
在步骤202中，发送所述网络切片选择辅助信息到所述RAN节点。In step 202, the network slice selection assistance information is sent to the RAN node.
本步骤中，所述终端可以基于所述连接建立消息发送携带初始NAS消息的连接建立完成消息到所述RAN节点，所述初始NAS消息和所述连接建立完成消息中携带所述网络切片选择辅助信息。RAN节点会根据所述网络切片选择辅助信息来确定与所述终端匹配的目标公共控制网络功能。In this step, the terminal may send a connection establishment complete message carrying an initial NAS message to the RAN node based on the connection establishment message, and the initial NAS message and the connection establishment complete message carry the network slice selection assistance information. The RAN node determines the target common control network function matching the terminal according to the network slice selection assistance information.
所述目标公共控制网络功能按照相关技术，根据所述初始NAS消息确定所述授权NAS消息。其中，所述授权NAS消息包括授权的网络切片选择辅助信息和临时标识，在该临时标识有效期内，终端可以在随后接入网络时，将临时标识提供给RAN节点，例如基站，RAN节点就会将NAS消息发送给所述目标公共控制网络功能。According to related technologies, the target public control network function determines the authorized NAS message according to the initial NAS message. Wherein, the authorized NAS message includes authorized network slice selection auxiliary information and a temporary identifier. During the validity period of the temporary identifier, the terminal may provide the temporary identifier to the RAN node, such as a base station, when subsequently accessing the network, and the RAN node will Sending a NAS message to said target common control network function.
在步骤203中，接收所述RAN节点根据所述网络切片选择辅助信息发送到所述终端的目标消息。In step 203, the target message sent by the RAN node to the terminal according to the network slice selection assistance information is received.
其中，所述目标消息中至少携带目标切片配置信息，所述目标切片配置信息至少包括终端所支持的所有核心网CN切片与RAN切片之间的映射关系。Wherein, the target message at least carries target slice configuration information, and the target slice configuration information at least includes mapping relationships between all core network CN slices and RAN slices supported by the terminal.
所述目标切片配置信息还包括以下至少一项：The target slice configuration information also includes at least one of the following:
终端所属的RAN切片区域；The RAN slice area to which the terminal belongs;
周期性RAN切片配置更新定时器；Periodic RAN slice configuration update timer;
其中，所述RAN切片区域通过RAN切片区域码表示或通过小区标识列表表示。Wherein, the RAN slice area is represented by a RAN slice area code or a cell identification list.
本步骤中，所述终端按照相关技术接收所述目标消息即可。In this step, the terminal only needs to receive the target message according to related technologies.
在步骤204中，根据所述目标消息，在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In step 204, according to the target message, a target RAN slice is determined among multiple candidate RAN slices corresponding to each supported core network slice.
本步骤中，可选地，所述核心网CN切片与RAN切片之间的映射关系包括：In this step, optionally, the mapping relationship between the core network CN slice and the RAN slice includes:
每个CN切片所对应的一个或多个RAN切片；One or more RAN slices corresponding to each CN slice;
其中，若一个CN切片对应于多个RAN切片，每个RAN切片对应于一个优先级，所述优先级可以按照RAN切片标识列表中各个RAN切片标识在列表中的顺序从高到低或从低到高表示，或用于指示每个RAN切片的优先级，CN切片按照所述优先级由高到底的顺序映射到RAN切片上。Wherein, if one CN slice corresponds to multiple RAN slices, each RAN slice corresponds to a priority, and the priority can be from high to low or from low to low according to the order of each RAN slice ID in the RAN slice ID list in the list to high, or used to indicate the priority of each RAN slice, and the CN slices are mapped to the RAN slices in the order of priority from high to low.
所述终端根据终端所支持的所有核心网CN切片与RAN切片之间的映射关系，将与当前核心网切片对应的多个所述备选RAN切片中，优先级级别最高的所述备选RAN切片作为目标RAN切片。例如图7所示，RAN切片区域A覆盖范围大，服务的CN切片最多。RAN切片区域B、C和D覆盖范围小，服务的CN切片少。将CN切片1映射到RAN切片A和RAN切片B，CN切片2映射到RAN切片A和RAN切片C。终端进入有RAN切片B覆盖区域时，CN切片1被映射到RAN切片C上，从而得到最优粒度的隔离，当终端里看RAN切片C覆盖的区域时，终端回退到RAN切片A，也可以得到次优的隔离。According to the mapping relationship between all core network CN slices and RAN slices supported by the terminal, the terminal selects the candidate RAN with the highest priority among the multiple candidate RAN slices corresponding to the current core network slice The slice serves as the target RAN slice. For example, as shown in Figure 7, the RAN slice area A has a large coverage area and serves the most CN slices. RAN slice areas B, C, and D have small coverage areas and serve few CN slices. CN slice 1 is mapped to RAN slice A and RAN slice B, and CN slice 2 is mapped to RAN slice A and RAN slice C. When the terminal enters the area covered by RAN slice B, CN slice 1 is mapped to RAN slice C, so as to obtain optimal granular isolation. When the terminal looks at the area covered by RAN slice C, the terminal falls back to RAN slice A, also Suboptimal isolation can be obtained.

Or the terminal determines that the update condition of the RAN slice area is met after determining that it has left the geographic location range corresponding to the previous target RAN slice area according to related technologies. At this point, the terminal automatically sends a RAN slice area update request to the RAN node.

In related technologies, after the location update occurs, the terminal will automatically send a location update request to the RAN node. At this time, the area of the RAN slice area is the same as the area of the tracking area of the terminal, and the RAN slice area multiplexes the tracking area code, and the RAN node does not need to separately indicate the RAN slice area to the terminal, and does not need to use the above update timer, and can directly use the location update timer.

所述RAN切片划分为多个层级，RAN切片除了顶层层级和底层层级之外的每个层级对应一个或多个下层层级，且对应一个上层层级；The RAN slice is divided into multiple levels, and each level of the RAN slice except the top level and the bottom level corresponds to one or more lower levels and corresponds to one upper level;
当CN切片与当前层级的RAN切片对应时，如果当前层级的RAN切片不存在，将所述CN切片对应到当前层级的上层层级的RAN切片上。When the CN slice corresponds to the RAN slice of the current level, if the RAN slice of the current level does not exist, the CN slice is corresponding to the RAN slice of the upper level of the current level.
同样地，将RAN切片划分成多个层级，对每一层级来说，除顶层层级和底层层级外，该层级可以对应一个或多个下层层级，但只对应一个上层层级。在需要将CN切片与当前某一个层级的RAN切片对应时，如果当前层级的RAN切片不存在，则可以将该CN切片对应到所述当前层级的上一层级的RAN切片上。Likewise, the RAN slice is divided into multiple levels, and for each level, except for the top level and the bottom level, the level may correspond to one or more lower levels, but only one upper level. When it is necessary to associate the CN slice with the RAN slice of a certain current level, if the RAN slice of the current level does not exist, the CN slice may be mapped to the RAN slice of the upper level of the current level.
如果该小区不支持该优先级的RAN切片，则跳到上一级别的RAN切片中去找支持该CN切片的RAN切片，直到找到为止。如果没有找到，则采用默认RAN切片。当然，所述终端可以在初始接入时、跟踪区域更新及网络请求等情况下上报配置的网络切片选择辅助信息。同样按照上述方式接收RAN节点返回的由目标公共控制网络功能返回的授权非接入层NAS消息。If the cell does not support the RAN slice of the priority, then jump to the RAN slice of the previous level to find the RAN slice supporting the CN slice until it is found. If not found, a default RAN slice is used. Certainly, the terminal may report the configured auxiliary information for network slice selection during initial access, tracking area update, and network request. The authorized non-access stratum NAS message returned by the target public control network function returned by the RAN node is also received in the above manner.
上述实施例中，无需终端支持基于切片区域的更新机制，终端可以通过读取每个小区的系统消息来直接进行切片区域配置和更新。进一步简化了切片配置的过程，使得一个RAN节点可以支持大量的CN切片，从而节省了RAN节点的无线资源，且提高了RAN节点的处理能力。In the above embodiment, it is not necessary for the terminal to support the update mechanism based on the slice area, and the terminal can directly configure and update the slice area by reading the system information of each cell. The process of slice configuration is further simplified, so that one RAN node can support a large number of CN slices, thereby saving the radio resources of the RAN node and improving the processing capability of the RAN node.
如图13所示，图13是根据一实施例的基础上示出的另一种网络切片配置的流程图，包括以下步骤：As shown in FIG. 13, FIG. 13 is a flow chart of another network slicing configuration shown on the basis of an embodiment, including the following steps:

其中，所述RAN切片区域通过RAN切片区域码表示或通过小区标识列表表示。Wherein, the RAN slice area is represented by a RAN slice area code or a cell identification list.
在步骤602中，终端获取预先配置的网络切片选择辅助信息。In step 602, the terminal acquires pre-configured network slice selection assistance information.
在步骤603中，所述终端从所述网络切片选择辅助信息中获取所述终端所配置的CN切片信息。In step 603, the terminal acquires CN slice information configured by the terminal from the network slice selection auxiliary information.
其中，所述CN切片信息包括CN切片对应的RAN切片级别信息。Wherein, the CN slice information includes RAN slice level information corresponding to the CN slice.
在步骤604中，所述终端根据所述目标切片配置信息和所述CN切片信息，在所支持的每个核心网切片所对应的多个备选RAN切片中确定目标RAN切片。In step 604, the terminal determines a target RAN slice among multiple candidate RAN slices corresponding to each supported core network slice according to the target slice configuration information and the CN slice information.
其中，所述核心网CN切片与RAN切片之间的映射关系包括：Wherein, the mapping relationship between the CN slice of the core network and the RAN slice includes:
所述RAN切片划分为多个层级，RAN切片除了顶层层级和底层层级之外的每个层级对应一个或多个下层层级，且对应一个上层层级；The RAN slice is divided into multiple levels, and each level of the RAN slice except the top level and the bottom level corresponds to one or more lower levels and corresponds to one upper level;
当CN切片与当前层级的RAN切片对应时，如果当前层级的RAN切片不存在，将所述CN切片对应到当前层级的上层层级的RAN切片上。When the CN slice corresponds to the RAN slice of the current level, if the RAN slice of the current level does not exist, the CN slice is corresponding to the RAN slice of the upper level of the current level.
上述实施例中，无需终端支持基于切片区域的更新机制，终端可以通过读取每个小区的系统消息来直接进行切片区域配置和更新。进一步简化了切片配置的过程，使得一个RAN节点可以支持大量的CN切片，从而节省了RAN节点的无线资源，且提高了RAN节点的处理能力。In the above embodiment, it is not necessary for the terminal to support the update mechanism based on the slice area, and the terminal can directly configure and update the slice area by reading the system information of each cell. The process of slice configuration is further simplified, so that one RAN node can support a large number of CN slices, thereby saving the radio resources of the RAN node and improving the processing capability of the RAN node.
