具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的网络架构100的示意图。该网络架构100可以包括：终端设备10、接入网设备20和核心网设备30。
终端设备10可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、用户代理或用户装置。可选地，终端设备10还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digita1 Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，第五代移动通信系统(5th Generation System，5GS)中的终端设备或者未来演进的公用陆地移动通信网络(Pub1ic Land Mobi1e Network，PLMN)中的终端设备等，本申请实施例对此并不限定。为方便描述，上面提到的设备统称为终端设备。终端设备10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端设备10。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的设备。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为接入网设备。可选地，通过接入网设备20，终端设备10和核心网设备30之间可以建立通信关系。示例性地，在长期演进(Long Term Evolution，LTE)系统中，接入网设备20可以是 演进的通用陆地无线网(Evolved Universal Terrestrial Radio Access Network，EUTRAN)或者EUTRAN中的一个或者多个eNodeB；在5G NR系统中，接入网设备20可以是无线接入网(Radio Access Network，RAN)或者RAN中的一个或者多个gNB。在本申请实施例中，所述的网络设备除特别说明之外，是指接入网设备20，如基站。
核心网设备30是部署在核心网中的设备，核心网设备30的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G NR系统中的核心网设备可以包括接入和移动性管理功能(Access and Mobility Management Function，AMF)实体、用户平面功能(User Plane Function，UPF)实体和会话管理功能(Session Management Function，SMF)实体等设备。
在一个示例中，接入网设备20与核心网设备30之间通过某种空口技术互相通信，例如5G NR系统中的NG接口。接入网设备20与终端设备10之间通过某种空口技术互相通信，例如Uu接口。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于LTE系统，也可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统，还可以适用于诸如窄带物联网(Narrow Band Internet of Things，NB-IoT)系统等其他通信系统，本申请对此不作限定。
为了支持RAN slicing，NW(Network，网络)通过广播或专用信息指示支持的切片信息给UE。具体切片信息可以为：
Frequency priority mapping for each slice(slice->frequency(ies)->absolute priority of each of the frequency)(每个切片的频率优先级映射(切片->频率->每个频率的绝对优先级))。
但是在MPS/MCS的配置和slice(切片)的配置共存或冲突的情况下，此时需要接入网设备通知UE，在进行RACH(Random Access Channel，随机接入信道)过程中，MPS/MCS优先或切片优先。
Network based solution is introduced to resolve the issue of prioritization parameter collision with MPS/MCS,i.e.,Network indicates whether slice override MPS/MCS or MPS/MCS override slice.(本申请提出了一种基于网络的解决方案，解决了优先级参数与MPS/MCS冲突的问题，即网络表示切片是否覆盖MPS/MCS或MPS/MCS覆盖切片)。
当UE有业务发起时，NAS(Non Access Stratum，非接入层)需要将AS(Access Stratum，接入层)层建立RRC连接，NAS需要根据业务属性来设置RRC建立原因值，并将RRC建立原因值通知给AS层，但是当UE配置为MPS UE或MCS UE时，UE在发起业务时设置的RRC建立原因值都为high priority(高优先级)，这样就与RACH过程中接入网设备所指示的MPS/MCS优先或切片优先不一致。
请参考图2，其示出了本申请一个实施例提供的RRC建立原因值的确定方法的流程图，该方法可以应用于图1所示的系统架构的终端设备中。该方法包括如下步骤。
步骤501：接收网络设备发送的指示信息。

综上所述，本实施例提供的方法，由网络设备向终端设备发送指示信息，通过指示信息指示目标业务与切片的优先关系，终端设备基于该优先关系确定RRC建立原因值。在目标业务优先时，基于目标业务确定RRC建立原因值；在切片优先时，基于切片确定RRC建立原因值，从而在确定RRC建立原因值时充分考虑目标业务与切片，使网络设备可以基于切片来进行接入控制。

步骤201：终端设备向核心网设备发送注册请求。
示例性的，网络设备包括核心网设备。
UE向AMF(Access and Mobility Management Function，接入和移动性管理实体)发送注册请求，注册请求中携带用户信息(终端设备的信息)及终端设备所请求的切片信息。
示例性的，步骤201的注册请求中所请求的切片信息，与，步骤221之后重新建立RRC连接时所请求的切片信息，可以相同也可以不同。
步骤211：核心网设备向终端设备发送注册接受消息，注册接受消息包括RRC建立原因值设置指示。

以目标业务为MPS/MCS为例，步骤201和步骤211中，UE处于连接态(NAS连接)，与核心网设备进行通信。在步骤220中，UE进入空闲态(NAS连接释放)；待UE重新有业务需要发起、需要建立RRC连接时，UE根据步骤221中的RRC建立原因值设置指示及本次RRC连接所请求的切片信息来设置RRC建立原因值。当MPS/MCS override slice时，UE设置RRC建立原因值为MPS/MCS或者high priority；当slice override MPS/MCS时，并且所请求的切片符合“slice override MPS/MCS”特征时，UE设置RRC建立原因值是slice override MPS/MCS或者MO data(Mobile Originated data，主叫数据业务)。

在一种可选的实施例中，在RACH中优先关系指示指示目标业务优于切片的情况下，终端设备通过非接入层设置RRC建立原因值为目标业务；或，在RACH中优先关系指示指示目标业务优于切片的情况下，终端设备通过非接入层设置RRC建立原因值为高优先级。
在一种可选的实施例中，在RACH中优先关系指示指示切片优于目标业务的情况下，终端设备通过非 接入层设置RRC建立原因值为切片优于目标业务；或，在RACH中优先关系指示指示切片优于目标业务的情况下，终端设备通过非接入层设置RRC建立原因值为主叫数据业务。
在一种可选的实施例中，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片符合切片优于目标业务特征的情况下，终端设备通过非接入层设置RRC建立原因值为切片优于目标业务；或，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片符合切片优于目标业务特征的情况下，终端设备通过非接入层设置RRC建立原因值为主叫数据业务。
在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片不符合切片优于目标业务特征的情况下，终端设备通过非接入层设置RRC建立原因值为目标业务；或，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片不符合切片优于目标业务特征的情况下，终端设备通过非接入层设置RRC建立原因值为高优先级。
以目标业务为MPS/MCS为例，AS将步骤214中的RACH中优先关系指示发送给NAS；当MPS/MCS overrideslice时，NAS设置RRC建立原因值为MPS/MCS或者highpriority；当sliceoverride MPS/MCS时，并且所请求的切片符合“sliceoverride MPS/MCS”特征时，NAS设置RRC建立原因值是sliceoverride MPS/MCS或者MO data。
示例性的，NAS向AS发送RRC建立原因值。
步骤230：终端设备向接入网设备发起RRC建立请求，RRC建立请求包括RRC建立原因值。
示例性的，终端设备通过AS向接入网设备发起RRC建立请求，RRC建立请求包括步骤225中设置的RRC建立原因值。
综上所述，本实施例提供的方法，由接入网设备向终端设备发送RACH中优先关系指示，通过RACH中优先关系指示指示目标业务与切片的优先关系，终端设备基于该优先关系确定RRC建立原因值。在目标业务优先时，基于目标业务确定RRC建立原因值；在切片优先时，基于切片确定RRC建立原因值，从而在确定RRC建立原因值时充分考虑目标业务与切片，使网络设备可以基于切片来进行接入控制。
(五)接入网设备向终端设备发送RACH中优先关系指示，由AS更改RRC建立原因值。
请参考图9，其示出了本申请一个实施例提供的RRC建立原因值的确定方法的流程图，该方法可以应用于图1所示的系统架构中。该方法包括如下步骤。
步骤214：接入网设备向终端发送RACH中优先关系指示。
RACH中优先关系指示承载在系统信息块SIB或专有信令消息中。专有信令消息可以为RRC释放消息(RRC release消息)。
示例性的，当MPS/MCS的配置和切片的配置共存或冲突时，接入网设备将通知UE在进行RACH过程中采用MPS/MCS优先或是切片优先。本申请实施例可以通过接入网设备所指示的RACH过程中的MPS/MCS和切片的优先关系，来确定RRC建立原因值。
示例性的，RACH中优先关系指示中可以指示具体哪个切片优先，即，slice可以包括具体的S-NSSAI value(Single Network Slice Selection Assistance Information value，单个网络切片选择辅助信息值)。例如，RACH中优先关系指示中包括第一切片优先。RACH中优先关系指示也可以包括具体的切片组，例如，RACH中优先关系指示指示第一切片组优先。即，RACH中优先关系指示中的切片可以包括具体的切片组信息,例如，RACH中优先关系指示中包括第一切片组优先(第一切片组优先于目标业务)。
步骤228：终端设备通过接入层基于RACH中优先关系指示更改RRC建立原因值。
在一种可选的实施例中，在RACH中优先关系指示指示目标业务优于切片的情况下，终端设备通过接入层维持RRC建立原因值为目标业务；或，在RACH中优先关系指示指示目标业务优于切片的情况下，终端设备通过接入层维持RRC建立原因值为高优先级。
在一种可选的实施例中，在RACH中优先关系指示指示切片优于目标业务的情况下，终端设备通过接入层更改RRC建立原因值为切片优于目标业务；或，在RACH中优先关系指示指示切片优于目标业务的情况下，终端设备通过接入层更改RRC建立原因值为主叫数据业务。
在一种可选的实施例中，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片符合切片优于目标业务特征的情况下，终端设备通过接入层更改RRC建立原因值为切片优于目标业务；或，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片符合切片优于目标业务特征的情况下，终端设备通过接入层更改RRC建立原因值为主叫数据业务。
在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片不符合切片优于目标业务特征的情况下，终端设备通过接入层维持RRC建立原因值为目标业务；或，在RACH中优先关系指示指示切片优于目标业务，且本次RRC连接所请求的切片不符合切片优于目标业务特征的情况下，终端设备通过接入层维持RRC建立原因值为高优先级。
以目标业务为MPS/MCS为例，当UE配置为MPS/MCS时，NAS设置RRC建立原因值为MPS/MCS 或者highpriority；当MPS/MCS overrideslice时，AS维持RRC建立原因值为MPS/MCS或者highpriorityaccess；当sliceoverride MPS/MCS时，并且所请求的切片符合“sliceoverride MPS/MCS”特征时，AS将RRC建立原因值更改为sliceoverride MPS/MCS或者MO data。
示例性的，在步骤228之前还可以包括步骤226和步骤227。步骤226：终端设备在终端设备配置为目标业务终端(MPS UE/MCS UE)的情况下，通过非接入层设置RRC建立原因值为目标业务或高优先级。步骤227：终端设备通过非接入层向接入层传递RRC建立原因值。
步骤230：终端设备向接入网设备发起RRC建立请求，RRC建立请求包括RRC建立原因值。
示例性的，终端设备通过AS向接入网设备发起RRC建立请求，RRC建立请求包括更改后的RRC建立原因值。
综上所述，本实施例提供的方法，由接入网设备向终端设备发送RACH中优先关系指示，通过RACH中优先关系指示指示目标业务与切片的优先关系，终端设备基于该优先关系确定RRC建立原因值。在目标业务优先时，基于目标业务确定RRC建立原因值；在切片优先时，基于切片确定RRC建立原因值，从而在确定RRC建立原因值时充分考虑目标业务与切片，使网络设备可以基于切片来进行接入控制。
