5G通信***引入了网络切片的概念，网络切片技术能够实现将一个物理网络划分为多个虚拟网络。一个虚拟网络当作一个“网络切片”，每个网络切片之间是相互独立的。一个终端中的不同协议数据单元(protocol data unit，PDU)会话可能需要与PDU会话相对应的网络切片来提供服务。
为使本领域技术人员更好的理解本申请，下面对本申请涉及到的网络切片的概念以及其它可能涉及到的背景技术进行简单说明：
网络切片作为5G的一项关键技术，在3GPP和其他各种国际标准化组织得到了广泛的重视和研究。其可以满足运营商对于各种工业、垂直市场和各种虚拟运营业务的定制化需求。网络切片是一个提供特定网络能力和网络特征的逻辑网络(Network Slice:Alogical network that provides specific network capabilities and network characteristics)。它可以是在物理或者虚拟的网络基础设施之上，根据不同的服务需求或者租户等定制化的有不同网络能力和网络特性的逻辑网络。网络切片由一组网络功能及其所需的资源(例如，计算资源、存储资源、网络资源)构成。
在本申请实施例中，网络切片可以简称为切片。
网络切片可以由操作、管理和维护***(operation，administration and maintenance，OAM)配置。单一网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)用于标识一个网络切片。
S-NSSAI包括以下至少之一：切片类型、服务类型(slice/service type，SST)信息，可选地，S-NSSAI还可以包括切片区分信息(slice differentiator，SD)。其中，SST信息用于指示网络切片的行为，例如网络切片的特征以及服务类型，SD信息是SST的补足信息，例如：若SST指向多个网络切片，那么SD可以辅助对应到唯一的一个网络切片。
终端中存在多种类型的业务，例如增强的移动宽带业务(enhanced mobile broadband，eMBB)，超可靠低时延通信(ultra-reliable low latency communications，URLLC)，海量机器类通信(massive machine type communication，mMTC)等，而不同类型业务的PDU会话对应的网络切片可能不同。终端中的不同应用可以对应于不同的业务类型，也就是说，终端中的应用可以对应不同的网络切片。需要说明的是，即使是相同的业务类型，由于提供的运营商或者业务提供商不同，也可能对应不同的网络切片。也就是说，网络切片可以给终端的至少一个PDU会话提供网络资源。
在已有的标准中，核心网通过向终端发送UE路由选择策略(UE route selection policy，URSP)，以使终端确定数据(可以理解为不同业务类型的应用的数据)的路由方式，URSP可用于指示需要在切片网络上传输的业务特征和切片网络激活参数，路由方式包括具体路由到哪个切片，或者是采用非切片网络传输数据。
示例性的，如图4为示例性示出的URSP的格式示意图，URSP包括但不限于：URSP规则长度(Length of URSP rule)字段、URSP规则的优先级(Precedence value of URSP rule)字段、业务描述符长度(Length of Traffic descriptor)字段、Traffic descriptor字段、路由选择描述符列表长度(Length of Route selection descriptor list)字段以及Route selection descriptor字段。
其中，Route selection descriptor list字段用于承载切片网络激活参数，切片网络激活参数包括但不限于：一个或多个切片对应的S-NSSAI等参数。
Traffic descriptor字段用于承载上文所述的需要在切片上传输的业务特征对应的信息(或参数)。其它字段的定义可参照3GPP标准中的描述，此处不赘述。
3GPP 24526协议中对于Traffic descriptor字段的描述如下：
Traffic descriptor component type identifier(业务描述符字段类型定义)
Bits(比特位)
8 7 6 5 4 3 2 1
0 0 0 0 0 0 0 1 Match-all type(全匹配类型)
0 0 0 0 1 0 0 0 OS Id+App Id type(操作***标识+应用标识类型)
0 0 0 1 0 0 0 0 IPv4 remote address type(ipv4远端地址类型)
0 0 1 0 0 0 0 1 IPv6 remote address/prefix length type(ipv6远端地址/前缀长度类型)
0 0 1 1 0 0 0 0 Protocol identifier/next header type(协议标识/下一个协议头类型)
0 1 0 1 0 0 0 0 Single remote port type(单个远端端口类型)
0 1 0 1 0 0 0 1 Remote port range type(远端端口范围类型)
0 1 1 0 0 0 0 0 Security parameter index type(安全参数索引类型)
0 1 1 1 0 0 0 0 Type of service/traffic class type(服务/业务等级类型)
1 0 0 0 0 0 0 0 Flow label type(流标签类型)
1 0 0 0 0 0 0 1 Destination MAC address type(目标MAC地址类型)
1 0 0 0 0 0 1 1 802.1Q C-TAG VID type(802.1Q用户标签虚拟局域网识别符类型)
1 0 0 0 0 1 0 0 802.1Q S-TAG VID type(802.1Q业务标签虚拟局域网识别符类型)
1 0 0 0 0 1 0 1 802.1Q C-TAG PCP/DEI type(802.1Q用户标签优先权代码点/丢弃指示器类型)
1 0 0 0 0 1 1 0 802.1Q S-TAG PCP/DEI type(802.1Q业务标签优先权代码点/丢弃指示器类型)
1 0 0 0 0 1 1 1 Ethertype type(以太网类型)
1 0 0 0 1 0 0 0 DNN type(数据网络名称(Data Network Name)类型)
1 0 0 1 0 0 0 0 Connection capabilities type(连接能力类型)
1 0 0 1 0 0 0 1 Destination FQDN type(目的全量域名(Full quality domain name)类型)
其中，OS Id+App Id组成应用描述符(Application descriptors)信息，用于标识操作***中的应用，也可以理解为，Application descriptors可用于指示操作***中的哪些应用可以通过切片网络传输数据。其中，OS Id用于标识操作***，App Id用于标识操作***中的应用。示例性的，App Id可以为应用的应用包名，即，UE从任一平台或商店下载并安装应用，应用的安装包中包含App Id，UE可在安装应用后，存储应用的安装包名。
需要说明的是，上述标准适用于终端与核心网之间的交互，也就是说，终端可通过当前应用的App Id及其它参数与核心网下发的URSP进行匹配，以将应用的数据路由至指定切片。但是，在存在CPE的应用场景中，由于现有CPE只具有转发功能，并没有对应的切片和接入CPE的UE以及UE的业务匹配。因此，在该场景中，CPE仅能通过URSP中的IP三元组(包括IPv4 remote address type或IPv6 remote address/prefix length type、Protocol identifier/next header type、Single remote port type)、DNN(即DNN type)和/或FQDN(即Destination FQDN type)的匹配方式，将应用的数据路由至相应切片。
但是，在一些场景中，用户可以在LAN侧签约不同的数据业务，例如，低时延业务、大带宽业务、定向业务等等。不同的数据业务对数据传输网络的需求不同。但是，CPE仅能根据URSP将UE中发送的数据路由至相应切片。但是，不同的UE可能签约了不同类型的网络业务，不同类型的网络业务对应不同的切片。目前，CPE并不能将UE的业务类型与不同的切片关联起来。这样，CPE不能满足UE差异化的网络需求。
下面结合图2所示的应用场景，对已有标准中的终端、CPE以及核心网的交互流程进行简单说明：
1)CPE接入核心网
结合图2，图5示出了本申请实施例中的CPE接入核心网的流程示意图，如图5所示，CPE接入核心网可以包括如下步骤：
S101，CPE向核心网发送注册请求Registration request消息。
具体的，CPE开机、重启或更新等情况下会发起注册流程，例如，CPE在开机后，将会发起注册流程，或者，CPE刷新后，也会发起注册流程，注册流程可以理解为CPE注册入网。
示例性的，参照图5，CPE向核心网发送Registration request消息，用于请求发起注册流程。示例性的，该Registration request消息中可携带注册类型、安全参数等信息，需要说明的是，对于核心网而言，CPE相当于UE，因此其具体发起注册的流程可参照已有标准中的UE注册流程，本申请不再赘述。
S102，核心网向CPE发送注册接受Registration accept消息。
具体的，核心网同意CPE注册入网后，向CPE发送Registration accept消息。该Registration accept消息中可以携带用于指示CPE接入核心网的一个或多个参数。示例性的，在本实施例中，Registration accept消息中携带允许网络切片选择辅助信息(Allowed Network Slice Selection Assistance Information，Allowed NSSAI)，用于指示允许CPE接入的一个或多个切片。
S103，CPE保存Allowed NSSAI。
示例性的，CPE可以将Allowed NSSAI保存至存储单元，例如CPE的内存中，以在后续的建立PDU session时使用。
S104，核心网向CPE发送管理终端策略命令Manage UE policy command消息。
具体的，核心网向UE发送Manage UE policy command消息，该消息中包括但不限于URSP。示例性的，如上文所述，URSP可以包括业务特征(例如IP三元组、App Id等等)和切片网络激活参数。
S105，CPE保存URSP。
具体的，CPE获取到来自核心网传输的URSP后，可以对URSP进行解码，以获取并存储URSP中各字段携带的参数及信息。
S106，CPE向核心网发送管理终端策略完成Manage UE policy complete消息。
具体的，CPE成功保存URSP包括的各参数后，可以向核心网发送Manage UE policy complete消息，以指示CPE已对URSP成功处理。
示例性的，如果CPE未能成功解析URSP或由于其他原因导致CPE未能成功保存URSP，则CPE向核心网发送管理终端策略命令失败Manage UE policy command reject消息。
2)UE接入CPE
具体的，在本申请实施例的通信***中，UE通过CPE接入核心网，图6示例性地示出了UE连接CPE的具体流程。如图6所示，UE接入CPE可以包括如下步骤：
S201，UE向CPE发送认证请求Authentication Request消息。
S202，CPE向UE发送认证响应Authentication Responce消息。
S203，UE向CPE发送关联请求Association Request消息。
S204，CPE向UE发送关联响应Association Responce消息。
CPE接收到UE发送的Association Response，确定UE成功接入CPE，或者可以理解为，成功通过CPE接入核心网。
上述步骤S201～步骤S204的具体细节及相关描述可参照802.11协议的标准，本申请不再赘述。
3)UE、CPE与核心网进行数据交互。
具体的，UE接入CPE后，UE与CPE之间的Wi-Fi通道建立。UE可通过其与CPE之间的Wi-Fi通道向CPE发送数据，并由CPE通过CPE与核心网之间的移动通信网络将数据转发至核心网。并且，CPE还可接收到核心网通过移动通信网络发送的对应于UE的数据。然后，CPE通过CPE与UE之间的Wi-Fi通道，将数据转发至UE。从而，可以实现UE与核心网之间的数据交互。
图7示例性地示出了UE、CPE与核心网交互的流程示意图，如图7所示，UE、CPE与核心网交互可以具体包括如下步骤：
S301，UE向CPE发送数据包1。
示例性的，UE通过与CPE之间的Wi-Fi通道，向CPE发送数据包1，数据包1的格式可以如图8A或者图8B所示。
参照图8A，具体的，UE与CPE之间为三层(即网络层)的数据交互，该数据包1也可以称为IP数据包，数据包1中可以携带数据部分以及IP包头(即为图中首部)，IP包头中包括固定部分(也可以成为固定字段)和可变部分(也可以称为可变字段)，其中，固定字段包括但不限于：目的地址、源地址等参数，可变字段包括可选字段和预留字段(也可以称为填充字段)。示例性的，固定部分所包括的字段是固定不变的，也就是说，UE向CPE发送的每个数据包均需要携带图8A中所示的固定部分中的各字段，字段中携带的信息可以相同，可以不同。可变部分所包括的各字段及各字段的长度均是可变的，也就是说，不同的UE，或者说是在不同的应用场景下，可变部分所包括的字段名称、位置及长度可以相同，也可以不同，本申请不做限定。需要说明的是，图8A所示数据包1格式中的各参数的名称及位置仅为示例性说明，本申请不做限定。
参照图8B，数据包1中可以携带数据部分以及IP包头(即为图中首部)，IP包头中包括固定部分(也可以成为固定字段)和可变部分(也可以称为可变字段)。其中，IP包头中固定部分可参考图8A中的描述，此处不再赘述。数据包1中的IP包头中的可选字段部分可以包括UE中发送数据包1的应用的App Id。需要说明的是，图8B中所示的App Id字段在可选字段中的位置仅为示意性举例，该字段的长度及位置可根据实际需求设置，本申请不做限定。
S302，CPE获取IP三元组。
示例性的，仅以核心网下发的URSP中包括IP三元组为例进行说明。CPE响应于接收到的UE发送的数据包1，获取IP三元组。
可选地，核心网下发的URSP中还可以包括App Id。CPE还可以从数据包1中获取UE中发送该数据包1的应用的App Id。
S303，CPE对IP三元组进行校验。
示例性的，CPE将获取到的IP三元组与S105保存的URSP指示的IP三元组进行匹配。若IP三元组匹配成功，即，IP三元组中的各参数均存在于核心网下发的URSP中。则CPE确定IP三元组校验成功，该IP三元组对应的数据包可路由到切片网络。
示例性的，如果IP三元组校验失败，即，IP三元组中的任一参数不存在于URSP中，则CPE确定校验失败，该数据包将路由到默认切片，通常情况下，默认切片为低优先级切片，或者，数据包将路由到非切片网络。
可选地，CPE还可以将从数据包1中获取到UE中发送该数据包1的应用的App Id，与URSP中的App Id进行匹配。若App Id匹配成功，即发送该数据包1的应用的App Id存在于核心网下发的URSP中。则CPE确定App Id校验成功，该App Id对应的数据包1可路由到URSP中App Id对应的切片。
可选地，CPE还可以将从数据包1中获取到UE中发送该数据包1的应用的App Id、以及IP三元组，与URSP中的App Id和IP三元组进行匹配。
S304a，CPE将数据包1路由到指定切片。
示例性的，CPE对IP三元组验证成功后，可进一步基于URSP中的其它信息，例如上文所述的切片网络激活参数等，获取切片的其它相关信息，例如切片的NSSAI。
示例性的，CPE可将切片的NSSAI与S103中存储的Allowed NSSAI进行匹配，以确定核心网是否允许UE的数据路由到该切片。
CPE将数据包1中的IP三元组与该切片对应的PDU session进行绑定，以使后续接收到的包含该IP三元组的数据包均可通过绑定的PDU session路由到对应切片。示例性的，绑定可以是指CPE将IP三元组与PDU session的相关信息(例如业务接口或者路由表项)对应记录在内存中，以使CPE检测到与该IP三元组对应的数据(即包括IP三元组的数据包)后，确定与IP三元组绑定的PDU session，并将数据路由到PDU session所对应的切片上。
这里，CPE可以在步骤S304a之前，已经将数据包1中的IP三元组与该切片对应的PDU session绑定。
可选地，CPE对App Id验证成功后，可进一步基于URSP中的其它信息，例如上文所述的切片网络激活参数等，获取切片的其它相关信息，例如切片的NSSAI。
一个示例中，如果CPE检测到未建立与该切片对应的PDU session，则需触发PDU session建立流程，仍参照图7，方法还包括：
S304b，CPE向核心网发送PDU session建立请求消息。
示例性的，CPE向核心网发起PDUsession建立流程，以建立对应于切片的PDU session。示例性的，PDU session建立请求消息携带所述IP三元组或App Id对应的切片的NSSAI。
S304c，核心网向CPE发送PDU session建立成功消息。
示例性的，核心网基于接收到的PDU session建立请求消息，建立与NSSAI对应的切片的PDU session，并在PDU session建立成功后，向CPE返回PDU session建立成功消息。
需要说明的是，PDU session建立流程的具体细节可参照已有标准中规定的PDU session建立流程，本申请不再赘述。
具体的，CPE接收到PDU session建立成功消息后，确定PDU session建立成功，并将IP三元组对应的数据流与PDU session进行绑定。
另一个示例中，若CPE检测到IP三元组或App Id对应的切片的PDU session已建立，则CPE直接将IP三元组、App Id与PDU session绑定，而无需执行PDU session建立流程。
可选地，核心网接收到数据包1之后，可以通过CPE向UE回复数据包2。具体，可参照图7，核心网接收到数据包1之后，UE、CPE与核心网交互具体还包括如下步骤：
S305，核心网向CPE发送数据包2。
示例性地，核心网可以在接收到数据包1后，基于数据包1生成数据包2，然后将数据包2发送给CPE。
可选地，核心网可以接收到另一个UE或者服务器发送的数据包。核心网对该数据包解析并封装成数据包2后发送给CPE。
可以理解的，本申请实施例对核心网如何生成数据包2、或者获取数据包2不作限定。
S306，CPE将数据包2发送给UE。
示例性地，CPE接收到核心网发送的数据包2后，可以解析该数据包2，确定该数据包2的目的接收设备，例如，UE。CPE可以将该数据包2发送给该目的接收设备，即UE。
关于UE、CPE与核心网下行数据传输流程可以参考已有标准中的描述，此处不再赘述。
图7中所示的过程是基于核心网下发的URSP所指示的业务特征(该业务特征可以包括但不限于App Id、IP三元组、DNN、FQDN中的一种或一种以上)进行校验，如果校验成功，则允许CPE将数据路由至切片网络。在一些场景中，用户可以开通不同的网络业务来体验差异化的网络服务。但是，CPE无法将用户开通的业务与切片进行关联，只能通过URSP来确定用户终端发送的数据匹配的切片。而根据URSP确定的切片有可能与用户所开通的业务对应的切片不一致，这样，无法为用户提供差异化的网络服务。举例来说，如果用户A的终端 开通了低时延网络业务，该低时延网络业务对应低时延切片。那么用户A的终端通过CPE向核心网发送数据时，CPE应该将该数据路由到低时延切片上。但是，若CPE仅按照URSP确定该用户A的终端发送的数据对应的切片为普通切片。那么用户A无法体验低时延的网络服务。
本申请实施例提供一种切片选择方法，CPE可以将UE的网络业务，与切片进行关联。CPE可以基于UE的网络业务来将该UE发送的数据路由与UE的网络业务关联的切片。这样，CPE可以给不同的UE提供差异化的网络服务。
在本申请实施例中提供的切片选择方法中，UE可以在CPE中签约网络业务。不同的网络业务可以与不同的切片关联。CPE可以基于UE签约的业务将UE发送的数据路由到UE所签约的业务对应的切片上。这样，UE可以体验差异化的网络服务。
图9示例性地示出了本申请实施例提供的一种切片选择方法。如图9所示，本申请实施例提供的一种切片选择方法可以包括如下步骤：
S401，CPE200接入核心网300。
在一些示例中，CPE200接入核心网300可以包括如下步骤：
1、CPE200中的调制解调器(modem)模块2003向核心网300发起注册。
这里，可以参考步骤S101中的描述，此处不再赘述。
2、核心网300可以向CPE200发送URSP和CPE200的签约信息。
示例性地，核心网300可以向CPE200的modem模块2003发送URSP和CPE200的签约信息。CPE200可以向运营商签约一个或多个网络业务。例如，运营商处可以提供网络业务的类型包括：大带宽高优先级业务，大带宽中优先级业务，大带宽低优先级业务，定向业务、低时延业务等等网络业务中的一个或多个。
可以理解的是，不同的运营商处的网络业务分类可能不同，网络业务的类型、名称也可能不同。本申请实施例对CPE200可以签约的网络业务的类型和名称不作限定。
在本申请实施例，定向业务可以运营商针对某一个公司的特定业务提供的网络业务。运营商可以提供一个或多个定向切片只对该特定业务提供网络服务，即只有UE100发送该特定业务的数据才能路由到运营商为该特定业务提供的切片上，其他业务的数据不能路由到该运营商为该特定业务提供的切片上。例如，运营商针对某一种游戏提供网络业务可以称为定向业务。运营商针对煤矿作业提供的网络业务也可以称为定向业务。运营商针对电网公司提供的网络业务也可以称为定向业务。可以理解的是，本申请实施例对具体的定向业务不作限定。
本申请实施例中，一种网络业务可以对应一种切片。不同的网络业务对应不同的切片。CPE200可以向运营商签约一个或多个网络业务可以是指，CPE200在运营商处开通使用一个或多个切片的权限。在本申请实施例中，CPE200具备使用第一切片的权限可以指，CPE200可以将数据路由到第一切片，可以通过第一切片将数据传输至核心网。
CPE200可以对核心网下发的URSP进行解析，CPE200可以解析出切片信息。该切片信息可以指示CPE200中能够使用的切片，以及能够提供给UE100的切片。
示例性地，参见图10，CPE200对URSP解析可以具体包括如下步骤：
S4011，CPE200按优先级遍历终端路由选择策略URSP列表。
示例性地，CPE200可以按照优先级遍历URSP列表。该URSP列表中可以多个URSP规则。可选地，URSP列表位置靠前的URSP规则的优先级高于位置靠后的URSP规则。
S4012，CPE200确定URSP列表中是否存在下一个优先级的URSP。若存在，执行步骤 S4013，若不存在，则执行步骤S40111。
可以理解的，CPE200可以先对URSP列表中最高优先级的URSP进行匹配，若最高优先级的URSP匹配成功，则不执行步骤S4012，若最高优先级的URSP匹配不成功，则匹配下一个优先级的URSP。
S4013，CPE200进行业务描述符Traffic descriptor匹配。
CPE200判断URSP规则的业务描述符所指示业务是否包括CPE200的业务，或者，判断URSP规则的业务描述符所指示业务是否与CPE200的业务相同。
S4014，CPE200确定Traffic descriptor是否匹配成功，若是，则执行步骤S4015，若否，则执行步骤S4012。
若CPE200确定Traffic descriptor指示的业务包括CPE200的业务，或者与CPE200的业务相同，则CPE200确定Traffic descriptor是否匹配成功。则CPE200执行步骤S4015。否则，CPE200继续执行S4012，查询下一条URSP规则。
S4015，CPE200遍历路由选择描述列表Route selection descriptor list。
CPE200逐条遍历路由选择描述列表Route selection descriptor list中的每个S-NSSAI。
S4016，CPE200确定S-NSSAI是否包含在allowed NSSAI，若是，则执行步骤S4017，若否，则执行步骤S4012。
CPE200确定路由选择描述列表Route selection descriptor list中的每个S-NSSAI是否包含在allowed NSSAI。若是，则执行步骤S4017。若否，则执行步骤S4012，即遍历下一条URSP规则。
S4017，CPE200选择S-NSSAI为PDU session激活参数。
S4018，CPE200确定DNN&NSSAI已经激活成功，若是，则执行步骤S4019，若否，则执行步骤S40110。
S4019，CPE200确定无需再激活PDU session。
S40110，CPE200用S-NSSAI激活PDU session。
S40111，CPE200确定切片选择失败。
若CPE200未遍历到次高优先级的URSP，则CPE200确定切片选择失败。
可以理解的，CPE200解析URSP的具体过程可以参考已有标准中的描述，此处不再赘述。
3、CPE200中的modem203可以向CPE200中的切片应用模块上报切片信息。
4、CPE200中的切片应用模块记录切片信息。
5、CPE200中的切片应用模块发起拨号。
6、CPE200中的modem203基于切片应用模块发起的拨号，建立多个切片的PDU session。
这里CPE200拨号，建立切片的PDU session的具体过程可以参考已有标准，此处不再赘述。
S402，UE100接入CPE200。
UE100接入CPE200的具体过程可以参考S201-S204中的描述，此处不再赘述。
在本申请实施例中，在UE100执行步骤S402之前或者之后，UE100可以进行身份认证以及签约网络业务。CPE200可以通过UE100的身份认证获取UE100的标识信息以及UE100签约的网络业务信息。
可选地，UE100可以通过Portal(门户网站或入口网页)认证来进行身份认证以及签约网络业务。
示例性，用户可以开启UE100中的Wi-Fi，在连接CPE200时，UE100可以显示用于身份认证的网页，用户可以在该网页中输入用户名和密码进行身份证。在UE100进行身份认证是，CPE200可以获取到UE100的MAC地址。
进一步地，UE100可以签约一项或多项CPE能够提供的网络业务。示例性地，图11示出了终端在签约CPE提供的网络业务的场景。如图11所示，终端1可以签约CPE提供的大带宽高优先级业务。终端2可以签约CPE提供的大带宽中优先级业务。终端3可以签约CPE提供的大带宽低优先级业务。终端4可以签约CPE提供的低时延业务。终端5可以签约CPE提供的多切片业务(即大带宽高优先级业务、大带宽中优先级业务、大带宽低优先级业务、低时延业务、定向业务等等业务中的多项业务)。终端6可以签约CPE提供的定向业务。
CPE200可以预先配置CPE能够提供的切片的名称，CPE可以将切片的名称与切片ID进行关联(或者称为绑定)。UE签约网络业务可以是指，UE在CPE中选定CPE能够提供的一种或者多种切片的名称后，CPE将该UE的标识与UE选定的切片的名称对应的切片关联。这样，UE具有使用该切片的权限。
在本申请实施例中，UE具有使用切片的权限可以指，UE发送的数据可以通过该切片传输至核心网(或者称为网络侧)。
可选地，CPE中可以有管理员用户，示例性地，通过USB或网口连接到CPE的终端可以称为管理员用户。本申请实施例对管理员用户不作限定。示例性地，该管理用户可以配置CPE200能够提供的切片的名称。以及，该管理员用户可以为其他UE签约CPE200能够提供的网络业务。
可以理解的是，CPE200中的SIM卡可以在运营商处签约一项或多项网络业务。CPE200能够提供给UE100的网络业务为CPE200中SIM卡在运营商处已签约过的网络业务。例如，CPE200中的SIM卡若在运营商处签约了低时延业务，那么CPE200可以给UE100提供低时延业务。只有当CPE200中的SIM卡在运营商处签约多项网络业务时，UE100才可以签约多切片业务。
进一步地，可选地，UE100可以通过登录网页签约CPE200能够提供的网络业务。或者，UE100可以通过管理员用户签约CPE200能够提供的网络业务。本申请实施例对UE100签约网络业务的方式不作限定。
示例性地，图12示出了一种用于签约网络业务的用户界面示意图。如图12所示，用户界面1200可以用于选择UE100签约的网络业务，并进行网络业务签约。用户界面1200中可以包括控件1201、控件1202、选项框1203、输入框1204、控件1205以及控件1206。用户点击控件1201和控件1202后，用户界面1200中可以显示选项框1203。用户可以在选项框中选择网络业务、在输入框1204中输入用户名(例如手机号码131********)。用户点击控件1205后，手机号码为131********的UE可以成功签约用户在选项框1203中所选定的网络业务。可选地，用户可以点击控件1206查看不同的网络业务对应的资费说明，或者用户所选定的网络业务对应的资费说明。
可以理解的是，UE100可以显示该用户界面1200，用户可以在该用户界面1200中为UE100签约网络业务。
可选地，CPE200的管理员用户的UE中也可以显示该用户界面1200。管理员用户可以在该用户界面1200中给不同的UE签约网络服务。
进一步地，当UE签约CPE200提供的网络业务后，CPE200可以将UE与该UE所签约的网络业务对应的切片进行关联(或者称为绑定)。
可选地，CPE200可以在数据库中记录UE的标识与其关联的切片或者该切片的ID。UE的标识可以是UE的MAC地址或者UE的手机号码，此处不作限定。
示例性地，在UE100进行portal认证时，CPE200可以保存UE的用户名，并且可以获取UE200的MAC地址。CPE200可以将UE100的用户名和MAC地址保存到portal信息数据库中。
示例性地，在UE100签约CPE200中能够提供的一项或多项网络业务后，CPE可以将UE100的用户名和UE100所签约的网络业务对应的切片ID建立关联关系，并保存到用户数据库中。CPE200可以将portal信息数据库保存的UE100的用户名和MAC地址刷新用户数据库，CPE200可以将UE100的用户名和MAC地址，与UE100所签约的网络业务对应的切片ID建立关联关系，并保存到用户数据库中。
可以理解的是，不同的UE可以签约同一项网络业务。CPE200中的一个切片ID可以与多个UE的用户名建立关联关系。
示例性地，在一种可能的实现方式中，CPE将UE100的用户名和UE100所签约的网络业务对应的切片ID建立关联关系之后，CPE200可以生成UE100的路由规则。该路由规则用于指示CPE200基于哪个PDU会话，将UE100的数据通过UE100签约的网络业务对应的切片传输至核心网。
S403，UE100向CPE200发送数据包R1。
UE100可以向CPE200发送数据包R1。该数据包R1可以是一种业务请求。该数据包R1中可以携带IP三元组，示例性地，该数据包的格式可以如图8A。可选地，该数据包还可以携带App Id，示例性地，该数据包的格式可以如图8B所示。可选地，数据包R1中还可以携带UE100的手机号码。此处对该数据包的具体格式不作限定。
示例性地，在一种可能的实现方式中，UE100向CPE200发送数据包R1包括：S403a，UE100将数据包R1发送给CPE200的Wi-Fi模块2001；S403b，CPE200中的Wi-Fi模块将数据包R1发送给CPE200中的路由模块2002。
S404，CPE200确定数据包R1对应的网络业务类型A1。
CPE200可以确定数据包R1对应的网络业务类型A1。具体地，CPE200可以先确定发送该数据包R1的UE100签约的网络业务。若UE100签约的网络业务仅包含为一项网络业务，且不是定向业务，则CPE200可以确定数据包R1对应的网络业务类型A1即为UE200签约的网络业务。
可选地，在一种可能的实现方式中，若该UE100签约的网络业务类型签约的网络业务为定向业务。则CPE200需要根据数据包R1中携带的业务特征(例如，IP三元组、或者IP三元组与App Id等等)与URSP中定向业务切片对应的业务特征进行匹配，若匹配成功，则CPE200确定数据包R1对应的网络业务类型A1为定向业务。若匹配不成功，则CPE200确定该数据包R1对应的网络业务A1为普通业务，即CPE200可以将该数据包R1路由到默认切片。
可选地，在一种可能的实现方式中，若该UE100签约的网络业务类型签约的网络业务为多切片业务，即包含多项网络业务，则CPE200需要根据数据包R1中携带的业务特征与URSP中多项网络业务所关联切片对应的业务特征分别进行匹配。若数据包R1中携带的业务特征与与URSP中多项网络业务中网络业务A2关联切片对应的业务特征匹配成功，则CPE200确定数据包R1对应的网络业务类型A1为网络业务A2。若匹配不成功，则CPE200确定该数据包R1对应的网络业务A1为普通业务，即CPE200可以将该数据包R1路由到默认切片。 可选地，一种可能的实现方式中，若匹配不成功，CPE200可以将该数据包R1路由到大带宽高优先级业务切片。这样，可以提高用户体验。
可选地，在一种可能的实现方式中，CPE200确定发送数据包R1对应的网络业务类型A1可以包括：CPE200确定发送数据包R1的UE100签约的网络业务，基于UE签约的网络业务确定数据包R1对应的网络业务类型A1。
示例性地，如图13所示，以CPE200与运营商签约了大带宽高优先级业务、大带宽中优先级业务、大带宽低优先级业务、低时延业务、定向业务等五种网络业务类型的网络业务为例进行说明，CPE200确定发送数据包R1对应的网络业务类型A1可以包括：
S4041，CPE200确定发送数据包R1的UE100签约的网络业务类型。
UE100签约的网络业务类型可以为大带宽高优先级业务、大带宽中优先级业务、大带宽低优先级业务、低时延业务、定向业务的一种或多项。
当UE100签约的网络业务类型可以为大带宽高优先级业务、大带宽中优先级业务、大带宽低优先级业务、低时延业务、定向业务的任一种或多种时，基于UE签约的网络业务确定数据包R1对应的网络业务类型A1包括如下几种情况：
情况1：UE100仅签约大带宽高优先级业务
S4042a，CPE200确定发送该数据包R1的UE100签约了大带宽高优先级业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了大带宽高优先级业务。
S4044a，CPE200确定网络业务类型A1为大带宽高优先级业务。
然后，CPE200可以确定网络业务类型A1为大带宽高优先级业务。
情况2：UE100仅签约大带宽中优先级业务
S4042b，CPE200确定发送该数据包R1的UE100签约了大带宽中优先级业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了大带宽中优先级业务。
S4044b，CPE200确定网络业务类型A1为大带宽高优先级业务。
情况3：UE100仅签约大带宽低优先级业务
S4042c，CPE200确定发送该数据包R1的UE100签约了大带宽低优先级业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了大带宽低优先级业务。
S4044c，CPE200确定网络业务类型A1为大带宽低优先级业务。
情况4：UE100仅签约定向业务
S4042d，CPE200确定发送该数据包R1的UE100签约了定向业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了定向业务。
S4043d，CPE200将数据包R1中的业务特征与URSP中定向业务的特征进行匹配。
S4044d，若匹配成功，则CPE200确定网络业务类型A1为定向业务。
可以理解的是，UE100签约了定向业务，UE100中只有特定应用才对应定向业务，其 他应用均不是定向业务。所以CPE200需要将数据包R1中的业务特征与URSP中定向业务的特征进行匹配，以确定该数据包R1是不是由该UE100中定向业务对应的特定应用发送的。若匹配成功，则CPE200确定网络业务类型A1为定向业务。若匹配不成功，则CPE200确定网络业务类型A1不是定向业务。
情况5：UE100仅签约低时延业务
S4042e，CPE200确定发送该数据包R1的UE100签约了低时延业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了大带宽低优先级业务。
S4044e，CPE200确定网络业务类型A1为低时延业务。
情况6：UE100签约了多切片业务
S4042f，CPE200确定发送该数据包R1的UE100签约了多切片业务。
示例性地，CPE200可以基于数据包R1中携带的UE100的MAC地址或者UE100的手机号码确定UE100签约了多切片业务。即UE100签约了大带宽高优先级业务、低时延业务、定向业务中的多项网络业务。
S4043f，CPE200基于数据包R1中的业务特征与URSP确定数据包R1对应的网络业务类型A1。
CPE200可以将数据包R1中的业务特征与URSP中的多切片业务中的每一种网络业务对应的业务特征分别进行匹配。若数据包R1中的业务特征与多切片业务中低时延业务的业务特征匹配成功，则CPE200可以确定数据包R1的网络业务类型A1为低时延业务。若数据包R1中的业务特征与多切片业务中定向业务的业务特征匹配成功，则CPE200可以确定数据包R1的网络业务类型A1为定向业务。若数据包R1中的业务特征与多切片业务中大带宽高优先级业务的业务特征匹配成功，则CPE200可以确定数据包R1的网络业务类型A1为大带宽高优先级业务。
在一种可能的实现方式中，若该数据包R1的业务特征与定向业务的业务特征、低时延业务的业务特征、以及大带宽高优先级业务均不匹配，则CPE200确定该数据包R1对应的网络业务A1为普通业务，即CPE200可以将该数据包R1路由到默认切片。
可选地，一种可能的实现方式中，若该数据包R1的业务特征与定向业务的业务特征、低时延业务的业务特征、以及大带宽高优先级业务均不匹配，则CPE200也可以确定该数据包R1对应的网络业务A1为大带宽高优先级业务，即CPE200可以将该数据包R1路由到大带宽高优先级业务切片。这样，可以提高用户体验。
可以理解的是，默认切片的数据传输速率低于上述定向切片、低时延业务切片、大带宽高优先级切片、大带宽中优先级切片、大带宽低优先级切片等切片的数据传输速率。大带宽高优先级切片的数据传输速率高于大带宽中优先级切片的数据传输速率。大带宽中优先级切片的数据传输速率高于大带宽低优先级切片的数据传输速率。S405，CPE200将数据包R1路由到网络业务类型A1对应的切片S1。
CPE200可以将数据包R1路由到网络业务类型A1对应的切片S1。
示例性地，参见图13，情况1：S4045a，在网络业务类型A1为大带宽高优先级业务的情况下，CPE200可以将数据包R1路由到大带宽高优先级业务切片。情况2：S4045b，在网络业务类型A1为大带宽中优先级业务的情况下，CPE200可以将数据包R1路由到大带宽中 优先级业务切片。情况3：S4045c，在网络业务类型A1为大带宽低优先级业务的情况下，CPE200可以将数据包R1路由到大带宽低优先级业务切片。情况4：S4045d，在网络业务类型A1为低时延业务的情况下，CPE200可以将数据包R1路由到定向业务切片。情况5：S4045e，在网络业务类型A1为定向业务的情况下，CPE200可以将数据包R1路由到低时延业务切片。
可选地，当CPE200解析出数据包R1中携带App Id时，CPE200可以将数据包R1重新封装，重新封装后的数据包R1不包括App Id以避免核心网侧无法识别可选字段中的App Id，导致兼容性问题。
可以理解的是，在一种可能的实现方式中，当CPE200确定UE100未签约CPE200提供的网络业务时，CPE200可以将该数据包R1路由到默认切片。
可选地，在一种可能的实现方式中，当CPE200确定UE100未签约CPE200提供的网络业务时，CPE200可以不将该数据包R1发送至核心网300。即，CPE200不为UE100提供网络服务。
可选地，核心网300还可以基于该数据包R1，发送业务响应R2。即可选地，本申请实施例提供的一种切片选择方法还可以包括步骤S406-步骤S408a、步骤S408b。
S406，核心网300向CPE200发送数据包R2。
核心网300可以基于UE100发送的数据包R1，通过CPE200向UE100发送数据包R2。
S407，CPE200确定数据包R2是否对应低时延业务切片。若是，则执行步骤S408b，若否，则执行步骤S408a。
CPE200可以确定数据包R2是否对应低时延切片。当CPE200在确定数据包R1对应低时延业务切片时，可以将该数据包R1的业务特征(例如IP三元组、或者IP三元组和App Id)加入特征表。当业务响应R2的业务特征与特征表中的业务特征相匹配时，CPE200可以确定业务响应对应低时延切片。否则，数据包R2不对应低时延业务切片。
可以理解的是，一般UE100上行发送的数据(例如，数据包R1)路由到低时延业务切片，那么下行接收到的数据(例如，数据包R2)。
S408a，若数据包R2不对应低时延业务切片，则向UE100发送数据包R2。
S408b，若数据包R2对应低时延业务切片，则将数据包R2进行加速发送给UE100。
若数据包R2对应低时延业务切片，则CPE200对下行传输该数据包R2的Wi-Fi链路进行加速。示例性地，若数据包R2是通过低时延业务切片发送到CPE200，则，CPE200可以确定该数据包R2对应低时延业务切片。然后，CPE200可以通过CPE200中的higame模块对传输该数据包R2的Wi-Fi链路进行加速。
这样，CPE可以将UE签约的网络业务与切片进行关联。然后，CPE200可以将签约了不同类型网络业务的UE发送的数据路由到不同的切片上。例如，若UE1签约了低时延业务切片，若UE2签约了大带宽高优先级业务，那么CPE200可以将UE1中应用A发送的数据路由到低时延业务切片，CPE200可以将UE2中应用A发送的数据路由到大带宽高优先级业务切片。这样，CPE200可以给用户提供差异化的网络服务。
在一些场景中，管理员用户还可以在CPE200中设置一个虚拟Wi-Fi接入点，并设置该虚拟Wi-Fi接入点的密码。管理员用户还可以将该虚拟Wi-Fi接入点的信息(例如，虚拟Wi-Fi接入点的名称和密码)与一个切片关联。连接该虚拟Wi-Fi接入点的UE发送的数据均可路由到同一个切片(即与虚拟Wi-Fi接入点的信息关联的一个切片)上。这样，可以避免每个用户需要单独操作来绑定切片或者付费接入，提高用户体验。
示例性地，以户外CPE多人玩游戏为例。管理员用户可以设定CPE200的虚拟Wi-Fi接入点。例如，该虚拟Wi-Fi接入点为xx游戏切片Wi-Fi，并设定Wi-Fi密码。管理员用户还可以将xx游戏切片Wi-Fi与xx游戏切片关联起来，可以理解的是，CPE签约了很多切片，其中包括xx游戏切片。通过该xx游戏切片Wi-Fi接入的UE均可以进行xx游戏切片业务。可选地，CPE可以将接入xx游戏切片Wi-Fi的UE的MAC地址和xx游戏切片进行关联并存储到数据库中。
这样，对于多人玩游戏，群组户外组团打游戏等场景也减少了用户认证的过程。
在上述CPE200设置有虚拟Wi-Fi连接点的场景中，本申请实施例提供的一种切片选择方法可以包括：
1，CPE200接入核心网。CPE200中设置有虚拟Wi-Fi接入点，并将Wi-Fi接入点的接入信息与切片S2关联。

3，UE100向CPE200发送数据包R1。
这里，可以参考上述步骤S403中的描述。
4，CPE200判断UE100是否接入虚拟Wi-Fi接入点，若是，则将该数据包R1路由到虚拟Wi-Fi接入点关联的切片S2；若否，CPE200可以执行上述步骤S404-S405。
在本申请实施例中，CPE200或CPE可以称为第一终端。UE、或者UE100、UE1、UE2均可以称为第二终端。数据包R1可以称为第一数据包，数据包R2可以称为第二数据包。切片S1所在的网络可以称为第一切片网络。
