为便于理解本申请实施例的技术方案，以下先对本申请实施例涉及到的几种类型的UE policy进行描述。
1)WLAN选择策略(WLAN Selection Policy，WLANSP)
WLANSP包含多个规则，WLANSP中规则称为WLANSP rule，WLANSP rule用于UE选择哪一个WLAN接入点时使用。
2)UE路由选择策略(UE Route Selection Policy，URSP)
URSP包含多个规则，URSP中的规则称为URSP Rule，每一个URSP Rule由业务描述(Traffic Descriptor)和一组路由选择描述(Route Selection Descriptor，RSD)组成。URSP的相关的内容如下表1和表2所示：
Figure PCTCN2019079141-appb-000001
表1:URSP Rule
Figure PCTCN2019079141-appb-000002
表2:RSD
3)V2X策略
UE policy的类型除了包括URSP、WLANSP以外，还可以在用途上进行区分，比如有些UE policy用于eMBB业务，有些UE policy用于V2X业务。进一步，V2X策略分为PC5策略和Uu接口策略。
UE policy的配置通过UE配置更新(UE Configuration Update，UCU)流程实现，如图2所示，该流程包括以下步骤：
步骤201：策略控制功能网元(Policy Control Function，PCF)决定更新UE policy。
步骤202：PCF将要更新的UE policy放在一个容器(Container)里，发送给核心接入和移动性管理网元(Core Access and Mobility Management Function，AMF)。
步骤203：AMF使用NAS消息将容器直接转发给UE。
3GPP规定了UE主动请求UE policy的流程，如图3所示，该流程包括以下步骤：
步骤301：UE向AMF发送UE policy请求消息。
步骤302：AMF向PCF发送UE policy控制更新消息。
步骤303：UE与PCF之间进行UE policy的配置流程。
这里，UE policy的配置流程参照图2所示的流程。
需要说明的是，UE可以同时从网络侧接收URSP、V2X策略等多种类型的UE policy。另一方面。图3所示的UE主动请求UE policy的流程只用于V2X业务的UE policy(即V2X策略)的请求。
图4为本申请实施例提供的策略确定方法的流程示意图一，如图4所示，所述策略确定方法包括以下步骤：
步骤401：终端接收网络设备发送的第一信息，所述第一信息包括以下至少之一：第一策略、第一策略对应的策略类型、第一策略对应的业务类型、是否允许终端请求第一策略的指示信息、终端请求第一策略的触发条件。
本申请实施例中，所述终端可以是手机、平板电脑、笔记本、车载终端、可穿戴式 设备等任意能够与网络进行通信的设备。
本申请实施例中，第一策略是指UE policy，所述第一策略对应的策略类型包括以下至少之一：V2X策略、高可靠低时延(Ultra Reliable&Low Latency Communication，URLLC)策略、物联网(Cognitive Internet of Things，CIoT)策略、WLAN选择策略、URSP策略、背景数据传输策略。所述第一策略对应的业务类型包括以下至少之一：V2X业务、URLLC业务、IoT业务、背景数据传输业务。
需要说明的是，策略类型可以是策略的名称不同，比如用于会话绑定的策略叫URSP策略、用于WLAN接入点选择的策略叫WLAN选择策略、用于车联网的策略叫V2X策略等。业务类型是指策略名称可以相同，但不同策略或不同的策略部分对应的业务(被用于的业务)不同，比如用于车联网的那部分策略对应于V2X业务、用于物联网的策略对应于物联网业务、用于低时延高可靠的策略对应于URLLC业务等，可以将UE policy对应到不同种类的业务。
本申请实施例中，UE policy通过以下方式传输：网络设备将UE policy分为一个或多个分段发送给终端，其中，每一个分段对应一个PSI。以下对UE policy内容的编制格式进行说明，UE policy内容的编制格式用于网络侧发送给终端UE policy时使用(见图2所示的流程)，UE policy的编制格式如图5-1至图5-7所示，其中，图5-1为UE policy section管理列表(management list)的信息单元(Information Element，IE)，包括UE policy section management list的长度和UE policy section management list的内容。进一步，图5-2为UE policy section management list的内容，包括N个UE policy section管理子列表(management sublist)。进一步，图5-3为UE policy section management sublist，包括PLMN和UE policy section management sublist内容，其中，PLMN有MCC和MNC组成。进一步，图5-4为UE policy section management sublist内容，包括N个Instruction。进一步，图5-5为Instruction，包括Instruction内容长度、UPSC和UE policy section内容。进一步，图5-6为UE policy section内容，包括N个UE policy部分；进一步，图5-7为UE policy部分，包括UE policy部分内容长度、备用(Spare)比特位、UE policy部分类型、UE policy部分内容。
本申请实施例中，终端能够感知获得的第一策略对应的策略类型，为实现此目的，有如下几种实现方式：
方式一：所述第一策略中的策略内容中包括第一指示信息，所述第一指示信息用于指示所述第一策略对应的策略类型和/或业务类型。进一步，所述第一策略中的策略内容中的策略类型字段和/或备用比特位字段包括所述第一指示信息。
举个例子：UE policy由策略标识和策略内容组成，在策略内容中添加第一指示信息，所述第一指示信息包括业务信息和/或策略类型信息。参照图5-7，可以利用“UE policy part type”字段(即策略类型字段)和/或spare比特位字段(即备用比特位字段)中增加新的值来区分策略类型。
方式二：所述第一策略中的策略标识中包括第二指示信息，所述第二指示信息用于指示所述第一策略对应的策略类型和/或业务类型。进一步，所述第一策略中的策略标识包括PLMN标识、第二指示信息和策略分段码(Policy Section Code，PSC)；或者，所述第一策略中的策略标识包括PLMN标识和PSC，所述PSC包含所述第二指示信息。
具体地，考虑到UE policy会划分成一个或多个分段，每一个分段会由一个PSI来标识，PSI是由PLMN标识(PLMN ID)和PSC组成的，新增加第二指示信息到PSI中，所述第二指示信息包括业务信息和/或策略类型信息。参照图6-1和图6-2，图6-1中，PSI由PLMN ID、业务标识(Service ID)和PSC组成；图6-2中，PSI由PLMN ID 和PSC组成，PSC进一步携带Service ID。
方式三：策略标识的取值与策略类型具有第一对应关系；所述第一对应关系用于所述终端基于所述第一策略中的策略标识确定所述第一策略对应的策略类型和/或业务类型。
这里，所述策略标识包括PLMN标识和PSC。
举个例子：可以通过协议约定UE policy的PSI的取值范围对应于特定的业务，也即对应特定的策略类型。参照图7，对于PSI(PLMN ID+PSC)，约定其不同的取值对应不同的业务类型，PSC＝1-30对应业务1，PSC＝31-50对应业务2，PSC＝51-80对应业务3。
方式四：所述第一信息包括第一参数，所述第一参数用于指示第一策略与策略类型和/或业务类型的对应关系；所述终端基于所述第一参数确定所述第一策略对应的策略类型和/或业务类型。
这里，所述第一策略与策略类型和/或业务类型的对应关系包括以下至少之一：
至少一个策略标识与策略类型和/或业务类型之间的对应关系；
至少一个策略规则与策略类型和/或业务类型之间的对应关系；
至少一个策略分段与策略类型和/或业务类型之间的对应关系。
这里，所述策略标识包括PLMN标识和PSC。
这里，可以添加新的参数指示业务信息，也即策略类型信息。比如：添加第一参数用于指示一个或多个UE policy Section对应于某一特定业务，在一个例子中，第一参数可以指示以下信息：
PSC1-PSC10对应业务1；
PSC15、PSC20、PSC24-26对应业务2；
PSC50、PSC65对应业务3。
在网络设备下发给UE Policy给终端时，可以直接将第一参数通知给终端。
方式五：策略的业务属性信息与策略类型具有第二对应关系；所述第二对应关系用于所述终端基于所述第一策略中的业务属性信息确定所述第一策略对应的策略类型和/或业务类型。进一步，所述业务属性信息包括以下至少之一：单网络切片选择辅助信息(Single-Network Slice Selection Assistant Information，S-NSSAI)、数据网络名(Data Network Name，DNN)、IP地址、MAC地址、应用标识、会话类型。
具体地，由于策略本身携带有S-NSSAI、DNN等业务属性信息，终端可以根据现有的业务属性信息来区分出策略对应的策略类型。
比如：Policy Section-1的S-NSSAI对应URLLC业务，Policy Section-1为URLLC策略，Policy Section-2的S-NSSAI对应V2X业务，Policy Section-2为V2X策略。
本申请实施例中，所述网络设备为PCF，所述第一信息由PCF封装在容器中发送给AMF，所述容器通过所述AMF透传给所述终端。进一步，所述容器通过所述AMF采用NAS消息发送给所述终端。这里，NAS消息可以是下行NAS传输(Downlink NAS Transport)消息。
通过本申请实施例上述技术方案，终端可以获知第一策略对应的策略类型，当终端向网络设备请求特定策略类型(或者说特定业务)的策略时，可以向网络侧发送第一请求消息，并指示更新特定策略类型(或者说特定业务)对应的策略。
本申请实施例中，所述终端请求第一策略的触发条件包括以下至少之一：第一策略到期时间、第一策略有效时间、发起第一请求消息的时间、发起第一请求消息的时间周期、发起第一请求消息的位置信息。所述终端根据触发条件确定何时向网络设备发送第一请求消息。
以下对终端有针对性的向网络请求特定策略类型(或者说特定业务)对应的策略进行描述。
图8为本申请实施例提供的策略确定方法的流程示意图二，如图8所示，所述策略确定方法包括以下步骤：
步骤801：终端向所述网络设备发送第一请求消息，所述第一请求消息包括第二信息，所述第二信息用于指示所述网络设备更新目标策略类型和/或目标业务类型对应的策略。
需要说明的是，本申请实施例中的“目标策略类型”和/或“目标业务类型”指的是终端向网络侧请求需要更新的那部分策略对应的策略类型和/或业务类型。
需要说明的是，终端向所述网络设备发送第一请求消息之前，网络设备可以向终端发送是否允许终端请求策略的指示信息和/或允许终端请求哪些策略的指示信息。这里，“允许”的相关描述也可以替换成“需要”。
本申请实施例中，所述第二信息可以通过以下任意一种方式来实现：
方式一：所述第二信息包括目标策略类型和/或目标业务类型对应的策略标识。
具体地，当终端需要主动更新策略或在注册请求时上报存储的PSI时，终端在上报PSI list时可以只上报特定策略类型(或者是特定业务)对应的PSI list，而不需要将本地存储的全部PSI list都上报。比如终端只上报V2X策略(V2X业务)对应的PSI list给网络侧，这样网络侧只会更新V2X业务相关的UE Policy(即V2X策略)。
参照图3所示的UE主动请求UE policy的流程，在步骤301中，UE向AMF发送UE policy请求消息中携带目标策略类型和/或目标业务类型对应的策略标识(或者是目标业务对应的策略标识)。
方式二：所述第二信息包括所述终端存储的策略标识和以下至少一种信息：目标策略类型、目标业务类型。
具体地，当终端需要主动更新策略或在注册请求时上报存储的PSI时，终端上报PSI list时也把其他业务对应的PSI上报上去(即终端上报全部业务的PSI list)，同时上报特定策略类型(或者是特定业务信息)，这样网络侧只给终端更新特定策略类型(或者是特定业务信息)对应的策略。比如终端向网络侧上报了全部存储的PSI的同时，还上报V2X策略(V2X业务)的指示信息，这样网络侧只会更新V2X业务相关的UE Policy(即V2X策略)。
方式三：所述第二信息包括目标策略类型和/或目标业务类型。
具体地，当终端需要主动更新策略时，终端上报目标策略类型和/或目标业务类型，比如终端向网络侧上报V2X策略(V2X业务)的指示信息，这样网络侧只会更新V2X业务相关的UE Policy(即V2X策略)。
参照图3所示的UE主动请求UE policy的流程，在步骤301中，UE向AMF发送UE policy请求消息中携带目标策略类型(或者是目标业务信息)。
本申请实施例中，所述网络设备为PCF，所述第二信息由终端封装在容器中发送给AMF，所述容器通过所述AMF透传给PCF。进一步，所述容器通过所述终端采用NAS消息发送给所述AMF。这里，NAS消息可以是上行NAS传输(Uplink NAS Transport)消息。
上述方案中，PSI也叫UPSI，PSI本身由PLMN ID和PSC组成。当终端执行注册流程或执行主动申请UE policy流程时，会在发给网络的NAS消息中携带自己存储的PSI列表(PSI list)，网络侧也就知道该终端已经存储了哪些策略，并据此进行更新。PSI list的编制格式如图9-1和图9-2所示，图9-1为UPSI列表的信息单元，包括PSI list内容的长度信息和N个UPSI子列表(UPSI sublist)；进一步，图9-2为 UPSI sublist，包括UPSI sublist的长度信息、PLMN和UPSC，其中，PLMN由MCC和MNC组成。
本申请实施例的技术方案，策略信息中将包含测量类型信息(或者说业务信息)，从而有助于终端判断策略属于哪种策略类型，从而可以针对性的请求网络进行特定策略类型的策略的更新。本申请实施例的技术方案充分使用了现有参数和流程，对现有系统的影响较小。
需要说明的是，上述图8相关的技术方案与图4相关的技术方案可以结合在一起进行实施，也可以独立进行实施。
