Description

一种网络切片选择方法、终端设备及网络设备
本申请要求于2016年9月28日提交中国专利局、申请号为201610859931.6、申请名称为“一种网络切片选择方法、终端设备及网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域，尤其涉及一种网络切片选择方法、终端设备及网络设备。
背景技术
随着多种多样的通信业务的不断涌现，不同的通信业务对网络性能的需求存在显著的区别，第五代移动通信系统(the fifth generation，5G)引入了网络切片(network slice，NS)的概念，以应对不同通信业务对网络性能的需求的差异。
网络切片是指支持特定通信业务需求的逻辑网络功能实体的集合，主要借助于软件定义网络(software defined network，SDN)技术与网络功能虚拟化(network function virtualization，NFV)技术，实现通信业务可定制化的服务。
为了满足同一终端设备能够支持多种通信业务，提高用户体验，目前允许同一终端设备接入多个网络切片。现有技术中由网络设备为终端设备选择并关联到合适的网络切片，即网络设备为该终端设备分配一个网络切片标识(network slice identification，NSID)，网络设备可以为无线接入网(radio access network，RAN)设备或者核心网(core network，CN)设备。
一种方案中，在终端设备与一个全球陆地移动网络(public land mobile network，PLMN)的注册过程中，网络设备根据终端设备的签约信息为该终端设备选择一个网络切片。此方案适用于终端设备与单一网络切片签约的场景，在终端设备与多个网络切片签约的情况下，网络设备仅根据该终端设备的签约信息无法为该终端设备选择一个合适的网络切片。
综上所示，针对同一终端设备与多个网络切片签约的场景，现有技术中存在网络设备无法为该终端设备选择一个网络切片的问题。
发明内容
本发明实施例提供了一种网络切片选择方法、终端设备及网络设备，用以针对同一终端设备与多个网络切片签约的场景，实现网络设备为该终端设备选择网络切片。
第一方面，本发明实施例提供的一种网络切片选择方法，包括：
终端设备产生第一信息后，向网络设备发送包括第一信息的第一消息，第一消息用于请求为终端设备选择网络切片，第一信息包括以下任一个或任意组合：第一网络切片信息、第一业务信息、终端设备的接入信息；终端设备接收网络设备发送的第二消息，第二消息用于指示网络设备为终端设备选择的网络切片。
由于终端设备向网络设备发送的第一信息，网络设备根据该第一信息为终端设备选择网络切片，因此可以实现网络设备为终端设备选择网络切片。针对同一终端设备与多个网络切片签约的场景，采用上述方法可以解决现有技术中网络设备仅根据该终端设备的签约 信息无法为该终端设备选择合适的网络切片的问题。
上述方法中，第一业务信息包括但不限于以下任一个或任意组合：业务的应用标识、流标识、数据包标识、隧道标识、无线承载标识、业务类别、用户使用类别、接入点地址、接入点标识。
终端设备的接入信息包括但不限于以下任一个或任意组合：终端设备的级别、随机接入信道RACH信道类别、随机接入前导序列。
这样，针对第一信息包括的不同信息，网络设备可以根据该不同信息为终端设备选择合适的网络切片。
在一种可能的设计中，第一信息包括第一网络切片信息时，可通过如下方法实现终端设备产生第一网络切片信息:
在终端设备预先配置唯一的网络切片标识的情况下，终端设备将唯一的网络切片标识作为第一网络切片信息；或者，
终端设备选择最高优先级的网络切片的网络切片标识作为第一网络切片信息；或者，
终端设备将自身发起的业务对应的网络切片的网络切片标识作为第一网络切片信息。
在一种可能的设计中，在终端设备预先配置有网络切片标识的情况下，终端设备产生第一网络切片信息之前，可接收网络设备发送的包括第二网络切片信息的第三消息，第二网络切片信息用于指示网络设备根据终端设备所在的位置选择的网络切片；终端设备根据第二网络切片信息预先配置网络切片标识。
由于第二网络切片信息用于指示网络设备根据终端设备所在的位置选择的网络切片，终端设备根据该第二网络切片信息预先配置网络切片标识，该预先配置网络切片标识若用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，在终端设备预先配置有网络切片标识的情况下，终端设备产生第一网络切片信息之前，终端设备接收网络设备发送第四消息，第四消息包括至少一个网络切片中各个网络切片对应的接入限制信息；终端设备根据第四消息，获知预先配置的网络切片标识指示的网络切片对应的接入限制信息，识别预先配置的网络切片标识指示的网络切片中能够接入的网络切片，保留能够接入的网络切片的标识。
这样，可实现终端设备在预先配置的网络切片标识中保留能够接入的网络切片的标识，若该能够接入的网络切片的标识用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，在终端设备预先配置有网络切片标识的情况下，终端设备产生第一网络切片信息之前，终端设备接收网络设备发送的第五消息，第五消息用于指示至少一个网络切片中能够接入的网络切片；终端设备根据第五消息，获知预先配置的网络切片标识指示的网络切片中能够接入的网络切片，保留能够接入的网络切片的标识。
这样，可实现终端设备在预先配置的网络切片标识中保留能够接入的网络切片的标识，若该能够接入的网络切片的标识用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，第一消息还包括网络功能实体标识。

上述方法中，第一业务信息包括但不限于以下任一个或任意组合：业务的应用标识、流标识、数据包标识、隧道标识、无线承载标识、业务类别、用户使用类别、接入点地址、接入点标识。
终端设备的接入信息包括但不限于以下任一个或任意组合：终端设备的级别、随机接入信道RACH信道类别、随机接入前导序列。
这样，针对第一信息包括的不同信息，网络设备可以根据该不同信息为终端设备选择合适的网络切片。
在一种可能的设计中，可通过如下方法实现网络设备根据第一信息为终端设备选择网络切片：
在第一信息包括第一网络切片信息的情况下，网络设备将第一网络切片信息指示的网络切片作为为终端设备选择的网络切片；或者，
在第一信息包括第一业务信息的情况下，网络设备根据第一业务信息指示的业务和业务与网络切片的映射关系，将第一业务信息指示的业务对应的网络切片作为为终端设备选择的网络切片；
在第一信息包括终端设备的接入信息的情况下，网络设备根据终端设备的接入信息为终端设备选择网络切片。
在一种可能的设计中，网络设备接收终端设备发送的包括第一信息的第一消息之前，还可以获取终端设备所在的位置；
网络设备选择终端设备所在的位置位于的服务范围对应的网络切片，并确定用于指示选择的网络切片的第二网络切片信息；
网络设备向终端设备发送包括第二网络切片信息的第三消息，第二网络切片信息用于终端设备预先配置网络切片标识。
由于第二网络切片信息用于指示网络设备根据终端设备所在的位置选择的网络切片，因此终端设备可根据该第二网络切片信息预先配置网络切片标识，该预先配置网络切片标识若用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，网络设备接收终端设备发送的包括第一信息的第一消息之前，还可以向终端设备发送第四消息，第四消息包括至少一个网络切片中各个网络切片对应的接入限制信息，第四消息用于终端设备识别能够接入的网络切片。
这样，可实现终端设备根据第四消息在预先配置的网络切片标识中保留能够接入的网络切片的标识，若该能够接入的网络切片的标识用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，网络设备接收终端设备发送的包括第一信息的第一消息之前，还可以向终端设备发送第五消息，第五消息用于指示至少一个网络切片中能够接入的网络切片，第五消息用于终端设备识别能够接入的网络切片。
这样，可实现终端设备根据第五消息在预先配置的网络切片标识中保留能够接入的网络切片的标识，若该能够接入的网络切片的标识用于网络设备为终端设备选择网络切片，因此能够更准确地为终端设备选择合适的网络切片。
在一种可能的设计中，网络设备根据第一信息为终端设备选择网络切片之后，还包括：
在第一消息还包括网络功能实体标识的情况下，网络设备将网络功能实体标识指示的网络功能实体作为为终端设备选择的网络功能实体；或者，

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供一种网络切片选择方法、终端设备及网络设备，用以针对同一终端设备与多个网络切片签约的场景，实现网络设备为该终端设备选择一个网络切片。其中，方法、终端设备及网络设备是基于同一发明构思的，由于方法、终端设备及网络设备解决 问题的原理相似，因此终端设备、网络设备与方法的实施可以相互参见，重复之处不再赘述。
网络切片是指支持特定通信业务需求的逻辑网络功能实体的集合，主要借助SDN技术与NFV技术。NFV技术可实现底层物理资源到虚拟化资源的映射、构建虚拟机和加载网络功能(network function，NF)；SDN技术可实现虚拟机之间的逻辑连接、构建承载信令和数据流的通路。网络切片最终实现RAN与CN的网络功能实体之间的动态连接，配置端到端的业务链，实现灵活组网，从而实现网络可定制化的服务。运营商可以根据各个具体通信业务对容量、覆盖、速率、时延以及可靠性等关键性能指标(key performance indicator，KPI)的需求确定网络切片，网络切片包括网络功能实体集合和运行这些网络功能实体所需的网络资源，从而为用户提供所需的电信服务业务和网络能力服务，满足特定的市场场景以及需求。
如图1所示为第三代合作伙伴计划(the third generation partnership project，3GPP)支持多个网络切片的网络框架示意图，3GPP将5G的网络切片的主要类型分为以下三大类：增强的移动宽带业务(enhanced mobile broadband，eMBB)类型的网络切片、海量机器类型连接业务(massive machine type communication，mMTC)类型的网络切片和超可靠低时延业务(ultra-reliable and low latency communications，URLLC)类型的网络切片。其中，eMBB类型的网络切片主要面向对速率和移动性有较高需求的终端设备，例如手机、多媒体设备等。mMTC类型的网络切片主要面向物联网的终端设备，该终端设备具有大规模、低移动性以及较低速率的需求。URLLC类型的网络切片主要面向车联网的终端设备，该终端设备对于时延和可靠性要求较高。例如，手机可接入eMBB类型的网络切片进行高速下载或者观看4K高清视频，传感器设备可以接入mMTC类型的网络切片进行小数据包的传输和系统配置的更新。
为了满足同一终端设备能够支持多种通信业务，提高用户体验，目前允许同一终端设备接入一个或多个网络切片，本发明实施例提供的技术方案可适用于同一终端设备接入一个或多个网络切片的场景。
本发明实施例可适用于5G系统或者LTE系统的进一步演进系统，示例性的，可采用如图2所示的系统框架，该系统框架内主要涉及终端设备、RAN、切片选择功能(slice selection function，SSF)实体、签约数据库(subscriber repository)、控制面的网络功能(CP NF)实体以及用户面的网络功能(UP NF)实体等。本发明实施例主要提供一种网络设备为终端设备选择网络切片的方法。
本发明实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端设备可以经RAN与一个或多个核心网进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端设备(Remote  Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)，本发明实施例中并不限定。按照业务类型划分，本发明实施例涉及的终端设备，可以是上文中对速率和移动性有较高需求的终端设备，例如手机、多媒体设备等，也可以是物联网的终端设备，还可以是车联网的终端设备。
本发明实施例所涉及的网络设备，可以是RAN设备、CN设备，主要用于为终端设备选择网络切片，即网络设备为终端设备分配网络切片标识。可以是接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备。网络设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互转换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。例如，网络设备可以是全球移动通信系统(Global System for Mobile Communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络设备(BTS，Base Transceiver Station)，也可以是带宽码分多址接入(Wide-band Code Division Multiple Access，WCDMA)中的网络设备(NodeB)，还可以是LTE中的演进型网络设备(evolutional Node B，eNB或e-NodeB)，本发明实施例中并不限定。
下面通过具体实施例详细说明本发明实施例提供的技术方案，需要说明的是，实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
实施例一
如图3所示，本发明实施例提供了一种网络切片选择方法，包括：
S301、终端设备产生第一信息，该第一信息包括以下任一个或任意组合：第一网络切片信息、第一业务信息、终端设备的接入信息。
第一信息可用于网络设备为终端设备选择网络切片。第一网络切片信息用于指示网络切片，第一网络切片信息可以是网络切片标识、网络切片的特征信息等。例如，第一网络切片信息可以包括网络切片对应的租户(Tenant)标识、支持某个业务类型的网络切片，支持某个业务类型的网络切片可以为eMBB类型网络切片、URLLC类型网络切片等。
可选的，第一网络切片信息还可以包括用户标识、网络功能实体标识、终端设备选择的公共陆地移动网络(Public Land Mobile Network，PLMN)标识等，例如，用户标识可以为国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)、全球唯一临时用户设备标识(Globally Unique Temporary UE Identity，GUTI)等。
可选的，第一业务信息用于指示终端设备发起的业务，例如，第一业务信息可以是业务的应用标识、流标识、数据包标识、隧道标识、无线承载标识、业务类别(Service Type)、用户使用类别(UE Usage Type)、接入点(Access Point Name，APN)地址、APN标识等。
上述第一业务信息在标准中已定义，下面进行简略说明：
业务的应用标识：用于唯一确定具体业务的应用层标识，比如用于指示微信业务、虚拟现实业务、车载业务等。一个网络切片可以承载一个或者一类业务，因此业务的应用标识与网络切片之间存在映射关系，第一业务信息中可包括业务的应用标识。
流标识：用于唯一确定承载业务流(flow)的标识，比如在业务流建立过程中添加该业务流的标识。一个网络切片可以承载一个或者一类业务流，因此流标识与网络切片之间存在映射关系，第一业务信息中可包括流标识。
数据包标识：用于唯一指示数据包类型，比如可以指示数据包归属某个业务或者网络切片，因此数据包标识与业务之间、数据包标识与网络切片之间存在映射关系，第一业务信息中可包括数据包标识。
隧道标识：用于唯一指示网络设备为终端设备建立的隧道(Tunnel)标识，隧道用于在核心网设备与接入网设备之间为终端设备传输特定的数据，比如为一个网络切片创建一个或者一组隧道，因此隧道标识与网络切片之间存在映射关系，第一业务信息中可包括隧道标识。
无线承载标识：用于唯一确定网络侧设备为终端建立的承载(Radio Bearer,RB)的标识，承载可以是信令承载(Signalling RB，SRB)、数据承载(Data RB，DRB)等，承载用于接入网设备为终端传输特定的数据，比如为一个网络切片创建一个或者一组承载，不同的网络切片可以使用不同的承载。因此无线承载标识与网络切片之间存在映射关系，第一业务信息中可包括无线承载标识。
业务类别：用于唯一确定业务类别的标识，比如用于指示eMBB业务、URLLC业务、mMTC业务等业务类型，一个网络切片可以对应一个业务类别，因此业务类别与网络切片之间存在映射关系，第一业务信息中可包括业务类别。
用户使用类别：用于唯一确定用户使用的终端设备的类型标识，比如适用于mMTC的终端设备、车载业务的终端设备等，mMTC的终端设备如传感器，只能进行mMTC的业务。比如指示终端设备网络制式的接入能力，如LTE网络的移动设备，只能进行LTE网络的业务，或者5G网络的移动设备，只能进行5G网络的业务。因此用户使用类别与业务类别之间、业务类别与网络切片之间存在映射关系，第一业务信息中可包括用户使用类别。
接入点地址、接入点标识：用于唯一确定用户使用哪种接入方式来访问网络，是用户接入网络时必须配置的参数，对于用户而言，可以访问的网络类型有很多，比如公共互联网，企业网络，紧急呼叫网络等。接入点地址或者接入点标识可以唯一确定用户访问的网络类型，网络切片可以有对应的接入点地址或者接入点标识，因此接入点地址与网络切片之间、接入点标识与网络切片之间存在映射关系，第一业务信息中可包括接入点地址或者接入点标识。
终端设备产生的第一业务信息包括上述信息的任一或者任意组合时，网络设备接收到第一业务信息后，可以第一业务信息包括的上述信息与网络切片之间的映射关系为终端设备选择的网络切片。
可选的，终端设备的接入信息可以是终端设备的级别、随机接入信道(Random Access Channel，RACH)的信道类别、随机接入前导序列等。上述终端设备的接入信息在标准中已定义，下面进行简略说明：
RACH的信道类别：用于指示终端设备发起随机接入请求的特定空口时域与频域资源的具体位置，一个或者多个网络切片可以对应一个或者一组专用RACH信道。比如为mMTC的终端设备配置特定的RACH信道，mMTC的终端设备发起接入时，网络设备便可以识别终端设备的设备类型，从而为终端设备选择针对mMTC的特定网络切片，可以实现隐式的包含网络切片标识信息，当然，终端设备的接入信息中也可以携带RACH的信道类别。
随机接入前导：用于指示终端设备发起随机接入时所用的正交序列信号，一个或者多 个网络切片可以对应一个或者一组专用随机接入前导。比如为mMTC的终端设备配置特定的随机接入前导，mMTC的终端设备发起接入时，网络侧设备便可以识别终端设备的设备类型，从而为终端设备选择针对mMTC的特定网络切片，可以实现隐式的包含网络切片标识信息，当然，终端设备的接入信息中也可以携带随机接入前导。
可选的，在第一信息包括第一网络切片信息的情况下，终端设备可采用以下方法之一产生第一网络切片信息：
在终端设备预先配置唯一的网络切片标识的情况下，终端设备将唯一的网络切片标识作为第一网络切片信息。
终端设备选择网络切片优先级最高的网络切片标识作为第一网络切片信息，不同网络切片的优先级可以是网络设备下发给终端设备的。比如，终端设备在预先配置至少两个网络切片标识的情况下，根据网络切片优先级，从预先配置的至少两个网络切片标识中选择网络切片优先级最高的网络切片标识作为第一网络切片信息。
其中，终端设备可以在全球用户识别卡(universal subscriber identity module，USIM)卡中预先配置网络切片标识。
终端设备将自身发起的业务对应的网络切片的网络切片标识作为第一网络切片信息，比如，终端设备在预先配置至少两个网络切片标识的情况下，根据自身发起的业务和业务与网络切片的映射关系，将自身发起的业务对应的网络切片的网络切片标识作为第一网络切片信息。又比如，终端设备在没有预先配置网络切片标识的情况下，根据自身发起的业务和业务与网络切片的映射关系，将自身发起的业务对应的网络切片的网络切片标识作为第一网络切片信息。
其中，业务与网络切片的映射关系可以是网络设备下发给终端设备的，例如网络设备可以通过无线资源控制(Radio Resource Control，RRC)消息或者非接入层(Non-access，NAS)消息或者媒体接入控制层(Medium Access Control，MAC)消息将业务与网络切片的映射关系通知给终端设备。
S302、终端设备向网络设备发送包括第一信息的第一消息，该第一消息用于请求为终端设备选择网络切片。
其中，第一消息为空口消息，例如可以是无线资源控制连接建立请求(Radio Resource Control Connection Request，RRC Connection Request)消息、RRC连接重建立请求(RRC Connection Reestablishment Request)消息、RRC连接重配置完成(RRC Connection Reconfiguration Complete)消息，NAS附着请求(Attach Request)消息、NAS业务请求(Service Request)消息、MAC层消息等。
通过S301中终端设备产生第一网络切片信息，S302中终端设备将产生的第一网络切片信息发送给网络设备的方法，可解决现有技术中另一种原因导致的网络设备无法为终端设备选择网络切片的问题。
现有技术的另一种网络切片选择的技术方案中，终端设备预设配置有网络切片标识，终端设备向网络设备上报一个网络切片标识，网络设备为该终端设备选择该网络切片标识指示的网络切片。此现有方案适用于终端设备预先配置单一网络切片标识的场景，在终端设备预先配置有多个网络切片标识的情况下，终端设备无法选择向网络设备上报哪一个网络切片标识，从而导致网络设备无法为该终端设备选择一个合适的网络切片。
而本实施例中，针对终端设备预先配置有一个或多个网络切片标识、或者终端设备没 有预先配置网络切片标识的场景，终端设备均可以向网络设备上报网络切片标识，克服了现有技术中的上述问题。
S303、网络设备根据第一信息为终端设备选择网络切片。
可选的，网络设备可采用以下方法之一为终端设备选择网络切片：
在第一信息包括第一网络切片信息的情况下，网络设备将该第一网络切片信息指示的网络切片作为为终端设备选择的网络切片。
在第一信息包括第一业务信息的情况下，网络设备根据该第一业务信息指示的业务和业务与网络切片的映射关系，将该第一业务信息指示的业务对应的网络切片作为为终端设备选择的网络切片。
在第一信息包括终端设备的接入信息的情况下，网络设备根据该终端设备的接入信息为终端设备选择网络切片。
例如，在终端设备的接入信息为终端设备的级别的情况下，网络设备可根据该终端设备的级别和预先配置的终端设备的级别与网络切片的映射关系，选择适合该终端设备的级别的网络切片作为为终端设备选择网络切片。终端设备的接入信息为RACH的信道类别时，网络设备可根据该RACH的信道类别和预先配置的RACH的信道类别与网络切片的映射关系，选择适合该RACH的信道类别的网络切片作为为终端设备选择网络切片。终端设备的接入信息为随机接入前导序列时，由于不同的网络切片对应的随机接入前导序列不同，网络设备可识别出该随机接入前导序列对应的网络切片，将该网络切片作为为终端设备选择网络切片。
需要说明的是，在终端设备没有向网络设备发送上述第一信息的情况下，网络设备可以不为终端设备选择网络切片，网络设备也可以根据网络切片优先级、网络切片的负载、网络拓扑、终端接入的无线技术类别(Radio Access Type，RAT)等因素为终端设备选择网络切片。
S304、网络设备向终端设备发送第二消息，该第二消息用于指示网络设备为终端设备选择的网络切片。
终端设备接收第二消息后，保存用于指示网络设备为自身选择的网络切片的信息，例如终端设备保存网络设备为自身选择的网络切片标识。
该第二信息可以包括网络切片标识、全球唯一临时标识(Globally Unique Temporary Identity，GUTI)、网络功能实体标识、网络切片的特征信息等信息，例如，网络切片对应的租户(Tenant)标识、支持某个业务类型的网络切片、网络切片支持的部分或者所有业务信息。其中，支持某个业务类型的网络切片可以为eMBB类型网络切片、URLLC类型网络切片等；网络切片支持的部分或者所有业务信息可以为应用标识、流标识、数据包标识、隧道标识、无线承载标识、Service Type、UE Usage Type、APN地址、APN标识等。
可选的，第二消息可携带网络切片标识、网络切片的特征信息等，用于指示网络设备为终端设备选择的网络切片。例如网络切片所在的小区的标识、频点、带宽、空口资源配合、接入控制配置等。
以第二消息可携带网络切片所在的小区为例，在第二消息携带的网络切片所在的小区不是终端设备接入的小区的情况下，终端设备可根据第二消息指示的网络切片所在的小区重新发起网络接入。
需要说明的是，如果第二消息指示的网络设备为终端设备选择的网络切片与终端设备 产生的第一网络切片信息指示的网络切片不同，以第二消息指示的网络设备为终端设备选择的网络切片为准。其中，第二消息为空口消息，例如可以是RRC连接建立(RRC Connection Setup)消息、RRC连接重建立(RRC Connection Reestablishment)消息、RRC连接重配置(RRC Connection Reconfiguration)消息，NAS附着回复(Attach Response)消息、NAS附着接受(Attach Accept)消息、NAS业务回复(Service Response)消息、NAS业务接受(Service Accept)消息、MAC层消息等。
由于不同的网络切片对应的随机接入前导序列不同，因此上述方法中，可采用随机接入前导序列替换网络切片标识来指示网络切片。
通过本实施例中的上述方法，可以实现网络设备为该终端设备选择网络切片。针对同一终端设备与多个网络切片签约的场景，通过本实施例中的上述方法，解决了现有技术中网络设备仅根据该终端设备的签约信息无法为该终端设备选择一个合适的网络切片的问题。
本实施例提供的一种网络切片选择方法中，网络设备可以为RAN设备。现有技术中，由于网络切片选择功能(slice selection function，SSF)模块存在于核心网，RAN设备在为终端设备选择网络切片时，需要RAN设备与CN交互多条信令，才能完成网络切片选择，导致信令开销较大，网络切片接入时延较大。通过本实施例提供的网络切片选择方法，可实现RAN设备为终端设备选择网络切片，RAN设备无需与CN交互多条信令，克服了现有技术中信令开销大、网络切片接入时延大的问题。
可选的，本实施例中还提供一种网络切片发现方法。在S301终端设备产生第一网络切片信息之前，终端设备可通过此方法预先配置网络切片标识。如图4所示，本实施例中还提供一种网络切片发现方法包括:
S401、网络设备获取终端设备所在的位置。
可选的，网络设备可以接收终端设备上报的自身所在的位置，网络设备也可以通过测量获取终端设备所在的位置。
S402、网络设备选择终端设备所在的位置位于的服务范围对应的网络切片，并确定用于指示选择的网络切片的第二网络切片信息。
不同的网络切片可覆盖不同的服务范围，网络设备可根据终端设备所在的位置发现适合该终端设备所在的位置的网络切片。
第二网络切片信息用于指示网络切片，第二网络切片信息可以包括网络切片标识，网络切片的特征信息等信息，例如网络切片对应的租户(Tenant)标识、支持某个业务类型的网络切片、网络切片支持的部分或者所有业务信息。其中，支持某个业务类型的网络切片可以为eMBB类型网络切片、URLLC类型网络切片等；网络切片支持的部分或者所有业务信息可以为应用标识、流标识、数据包标识、隧道标识、无线承载标识、Service Type、UE Usage Type、APN地址、APN标识等。
可选的，第二消息可携带网络切片标识、网络切片的特征信息等，用于指示网络设备为终端设备选择的网络切片。例如网络切片所在的小区的标识、频点、带宽、空口资源配合、协议栈配置、接入控制配置等。
S403、网络设备向终端设备发送包括第二网络切片信息的第三消息。
其中，第三消息是空口消息，例如可以是RRC系统消息块(System Information Block，SIB)消息、RRC连接建立消息、RRC连接重配置消息、NAS附着回复(Attach Response) 消息、NAS业务回复(Service Response)消息、MAC层消息等。
其中，网络设备可以通过RRC消息或者NAS消息或者MAC消息，以广播或者组播或者单播的方式向终端设备发送该第三消息。
S404、终端设备根据第二网络切片信息预先配置网络切片标识。
可选的，在S402之前，终端设备可以向网络设备上报自身感兴趣的网络切片的信息和/或自身发起的业务信息，例如网络切片标识和/或业务标识，此时S402中网络设备可结合终端设备所在的位置和终端设备上报的信息确定第二网络切片信息，具体方法如下：
在终端设备向网络设备上报自身感兴趣的网络切片的信息的情况下，当终端设备所在的位置位于上报的网络切片信息对于的服务范围内或附近时，网络设备将终端设备上报的自身感兴趣的网络切片的信息作为第二网络切片信息。
在终端设备向网络设备上报自身发起的业务信息的情况下，当终端设备所在的位置位于上报的业务信息对于的服务范围内或附近时，网络设备将终端设备上报的业务信息对应的网络切片的信息作为第二网络切片信息。不同的网络切片可覆盖不同的服务范围，不同的网络切片可支持不同的业务。
通过本实施例提供的一种网络切片发现方法，网络设备可以根据终端设备所在的位置、终端设备上报的自身感兴趣的网络切片的信息、自身发起的业务信息向终端设备推荐网络切片，以便终端设备发现并预先配置网络切片。这样，对于特定服务范围对应的网络切片，终端设备可以发起有针对性的网络切片选择请求，避免出现由于终端设备盲目发起网络切片选择请求造成的网络切片选择失败的问题。
可选的，本实施例中还提供两种网络切片接入限制检查方法。在S301终端设备产生第一网络切片信息之前，终端设备可通过此方法判断预先配置的网络切片是否可以接入。
如图5所示，本实施例提供的一种网络切片接入限制检查方法包括:
S501、网络设备向终端设备发送第四消息，该第四消息包括至少一个网络切片中各个网络切片对应的接入限制信息。
其中，第四消息是空口消息，例如可以是RRC系统消息块(System Information Block,SIB)消息、RRC连接建立消息，RRC连接重配置消息，NAS附着回复(Attach Response)消息、NAS业务回复(Service Response)消息或者MAC层消息等。第四消息可以以广播、组播或者单播的方式发送给终端设备。
网络切片对应的接入限制信息包括但不限于接入限制时间(access barring time)和接入限制因子(access barring factor)，网络切片对应的接入限制信息可以列表的形式存在。
需要说明的是，第四消息可以是与上文中的第三消息可以是同一个消息，第四消息也可以是与第三消息不同的消息，第四消息和第三消息可以同步发送，也可以不同步发送。
需要说明的是，第四消息包括的至少一个网络切片中各个网络切片对应的接入限制信息，可以采用多种表现形式。例如，可根据网络切片属性将网络切片划分成不同类别，每个网络切片类别可包括一个或多个网络切片，每一个网络切片类别对应一个接入限制信息。又例如，将网络切片随机分组，每组网络切片可包括一个或多个网络切片，每组网络切片对应一个接入限制信息。
S502、终端设备根据第四消息，获知预先配置的网络切片标识指示的网络切片对应的接入限制信息，识别该预先配置的网络切片标识指示的网络切片中能够接入的网络切片，保留该能够接入的网络切片的标识。
例如，终端设备获知预先配置的网络切片标识指示的网络切片对应的接入限制信息之后，对一个预先配置的网络切片标识指示的网络切片是否可以接入进行判断：
网络切片对应设置有接入限制定时器。在该网络切片设置的接入限制定时器正在运行的情况下，终端设备确定该网络切片不可以接入。
否则，终端设备采用随机数算法选择一个介于0与1之间的均匀分布的随机数；如果该随机数小于网络切片对应的接入限制因子，则终端设备确定该网络切片可以接入。如果该随机数大于或等于网络切片对应的接入限制因子，则终端设备确定该网络切片不可以接入，并且终端设备启动该网络切片对应的接入限制定时器，该接入限制定时器的定时长度为(0.7+0.6*随机数)*接入限制时间。
如图6所示，本实施例提供的另一种网络切片接入限制检查方法包括:
S601、网络设备向终端设备发送第五消息，该第五消息用于指示至少一个网络切片中能够接入的网络切片。
其中，第五消息是空口消息，例如可以是RRC系统消息块(System Information Block,SIB)消息、RRC连接建立消息，RRC连接重配置消息，NAS附着回复(Attach Response)消息、NAS业务回复(Service Response)消息或者MAC层消息等。
网络设备可通过广播或者组播的方式向终端设备发送第五消息。例如，第五消息指示不同等级的网络切片中能够接入的网络切片，可以通过网络切片接入等级地图指示不同等级的网络切片中能够接入的网络切片。例如网络切片接入等级地图中，“0”表示对应的等级的网络切片可以接入，“1”表示对应的等级的网络切片不可以接入。第五消息还可以指示网络拒绝接入的原因，例如指示拒绝接入的网络切片标识。第五消息还可以指示网络切片的退避时间，终端设备需要等待退避时间长度后才能再次发起网络切片接入。
S602、终端设备根据第五消息，识别预先配置的网络切片标识指示的网络切片中能够接入的网络切片，保留该能够接入的网络切片的标识。
例如，终端设备获知网络切片接入等级地图之后，对一个预先配置的网络切片标识指示的网络切片是否可以接入进行判断：
终端设备获知网络切片的等级。终端设备可在USIM卡中保存有不同网络切片的等级，也可接收网络设备发送的用于指示不同网络切片的等级的消息，该用于指示不同网络切片的等级的消息可以为空口消息，例如RRC连接重配置消息。
终端设备根据该网络切片的等级，在网络切片接入等级地图中查找该网络切片是否可以接入。
进一步地，通过上述两种方法判断预先配置的网络切片是否可以接入之后，可根据判断结果对预先配置的网络切片进行处理。对于不可以接入的网络切片，终端设备可在预先配置的网络切片标识中删除该不可以接入的网络切片对应的网络切片标识，后续终端设备将不会针对该不可以接入的网络切片向网络设备发起网络切片选择请求。对于可以接入的网络切片，终端设备保留其对应的预先配置的网络切片标识，后续终端设备可针对该可以接入的网络切片向网络设备发起网络切片选择请求。
上述两种方法中，网络设备根据不同网络切片的负载情况向终端设备指示不同网络切片是否可以接入，以实现根据网络切片的负载情况对网络切片进行接入控制。
可选的，本实施例中还提供一种网络功能实体选择方法。在网络设备为终端设备选择网络切片之后，网络设备可通过该方法为终端设备选择网络功能实体。如图7所示，本实 施例中还提供一种网络功能实体选择方法包括：
S701、网络设备为终端设备选择网络功能实体。
在S302中第一消息还包括网络功能实体标识，或者终端设备向网络设备发送的其他消息包括网络功能实体标识的情况下，网络设备将该网络功能实体标识指示的网络功能实体作为为终端设备选择的网络功能实体。
在终端设备没有向网络设备指示网络功能实体，或者网络设备根据终端设备发送的网络功能实体标识不能正确寻址到网络功能实体的情况下，网络设备可以根据第一信息中携带的第一网络切片信息、第一业务信息和终端设备的接入信息任一或任意组合，在与自身相连的网络功能实体中选择支持为终端设备选择的网络切片的网络功能实体作为为终端设备选择的网络功能实体。例如第一网络切片信息可以为网络切片标识，网络切片类型等。
网络设备在为终端设备选择网络功能实体时也可考虑网络功能实体的负载、网络拓扑、终端接入的RAT等因素。
S702、网络设备向终端设备发送用于指示为终端设备选择的网络功能实体的消息。
S703、终端设备保存用于指示网络设备为自身选择的网络功能实体的信息。
例如，终端设备保存网络设备为自身选择的网络功能实体的标识。
其中，网络功能实体包括控制面(User Plane，UP)网络功能实体和用户面(Control Plane，CP)网络功能实体。
现有技术中，网络切片选择过程与网络功能实体选择过程是分开执行的，造成终端设备需要两次RRC连接建立才能实现与网络功能实体连接，从发起并建立业务。通过本实施例提供的方法，可实现网络设备为终端设备选择网络功能实体，终端设备无需通过两次RRC连接建立才能实现与网络功能实体连接。
本发明实施例提供的上述技术方案中，网络设备根据终端设备发送的第一信息为终端设备选择网络切片，并向终端设备指示网络设备为终端设备选择的网络切片，该第一信息包括以下任一个或任意组合：第一网络切片信息、第一业务信息、终端设备的接入信息。因此，通过本发明实施例提供的技术方案可以实现网络设备为终端设备选择网络切片，针对同一终端设备与多个网络切片签约的场景，通过本发明实施例提供的技术方案可以解决现有技术中网络设备仅根据该终端设备的签约信息无法为该终端设备选择一个合适的网络切片的问题。
