其中，所述应用数据包括业务信息，该业务信息是用于标识业务的信息，例如业务信息可以是应用标识(application identifier，APP ID)或者业务流信息。比如，该业务信息可以是已有的DNN标识的网络中新部署的应用或者业务所对应的业务信息。或者，该业务信息可以是动态部署的数据网络中的应用或者业务所对应的业务信息，如新部署的LADN网络中的应用或者业务所对应的业务信息。
可选地，应用数据还可以包括下述中的一项或多项：DNN、S-NSSAI、SSC模式、位置信息、时间信息、UE标识和群组标识。
其中，DNN用于标识一个数据网络。该DNN指示该业务信息对应的数据网络，即，该数据网络提供该业务。
S-NSSAI指示该业务信息对应的业务所关联的网络切片信息，UE通过该S-NSSAI可以接入该业务。
SSC模式是指业务信息对应的业务对连续性的需求，即接入业务的UE发生移动时，网络是否需要保证业务的连续性。
位置信息用于指示该业务信息对应的业务的有效区域。也就是说，只有在该位置信息所指示的区域，才能接入该业务。
时间信息用于指示该业务信息对应的业务的有效时间，或者时间信息用于指示该业务信息对应的业务的有效时间。即，只有在该时间信息所指示的时间内，才能接入该业务。或者，只有在该时间信息所指示的时间内，该应用数据才有效。
UE标识和群组标识均指示能够应用业务信息对应的业务的UE，其中能够应用该业务信息对应的业务的UE包括前述UE。也就是说，该业务信息只针对部分UE有效。
可选地，UE标识和/或群组标识可以不做为应用数据的部分提供给第一网元。此时所述应用数据可以包含业务信息，可选的包含DNN、S-NSSAI、SSC模式、位置信息、时间信息中的一项或者多项。
本申请中，所述应用数据可以由AF通过NEF直接或间接地发送给第一网元，然而再由第一网元直接或间接地发送给第一PCF。
在一种实现方式中，第一网元为AMF。其中，AMF的所述应用数据是NEF发送给UDM的。也就是说，NEF可以先向UDM发送该应用数据，然后UDM再把该应用数据发送给AMF。

可选地，第一网元向第一PCF发送应用数据，包括：第一网元根据第一PCF的请求向第一PCF发送应用数据。
例如，若在第一网元获取到所述应用数据后，UE才发起注册流程，则在注册过程中，第一网元可以向第一PCF请求所述应用数据，第一网元根据第一PCF的请求向第一PCF发送所述应用数据。
另外，第一网元也可以直接将应用数据推送给第一PCF。例如，UE在注册过程中，向第一网元订阅了该UE的业务更新通知。那么，在第一网元获取到所述应用数据之前，若UE已经注册到网络，则第一网元可以直接将应用数据推送给第一PCF。
可选地，第一网元向第一PCF发送应用数据，包括：第一网元根据所述应用数据，确定至少一个PCF，并向所述至少一个PCF发送应用数据。其中，所述至少一个PCF包括第一PCF。

或者，所述至少一个H-PCF可以是向该UDR请求应用数据的H-PCF。比如，所述至少一个H-PCF可以分别向该UDR发送请求消息，该请求消息用于请求该应用数据，该请求消息可以不包括UE的标识信息，该UDR可以根据该请求消息，分别向该至少一个H-PCF发送该应用数据。
应理解，方式一与UE是否注册网络没有关系。也就是说，无论UE是否注册到了网络，或者是否正在发起注册流程，UDR都可以向所述至少一个H-PCF发送应用数据。
方式二
UDR接收到NEF发送的应用数据后，向特定的H-PCF发送特定UE的应用数据。
在一个示例中，针对任一UE，在该UE注册过程中，服务该UE的H-PCF可以向UDR发送订阅消息，该订阅消息用于订阅业务更新通知，该订阅消息可以包括该UE的标识信息。若UE注册完成后，UDR接收到该UE的应用数据，则UDR可以向该H-PCF发送该应用数据。比如，UDR接收到包括该UE的标识信息的应用数据，或者NEF向UDR发送的携带该应用数据的消息包括该UE的标识信息，则UDR可以向该H-PCF发送Nudr_DM_Notify消息，该消息可以包括该UE的应用数据。
在另一个示例中，针对任一UE，在该UE注册到网络后，服务该UE的H-PCF可以向UDR发送请求消息，该请求消息用于请求该UE的应用数据，比如该请求消息可以包括该UE的标识信息。UDR接收到该请求消息后，若确定存储了该UE的应用数据，即，UDR之前从NEF接收到了该UE的应用数据，则可以向该H-PCF发送该UE的应用数据。
在又一个示例中，在UE注册过程中，服务该UE的AMF可以通过向H-PCF发送请求消息#1，例如Npcf_UEPolicyControlCreate请求消息，请求消息#1用于请求与H-PCF建立UE策略关联。H-PCF可以根据该请求消息#1，向UDR请求消息#2，请求消息#2用于请求应用数据，请求消息#2可以包括该UE的标识信息。UDR接收到请求消息#2后，若确定存储了该UE的应用数据，即，UDR之前从NEF接收到了该UE的应用数据，则可以向H-PCF发送该UE的应用数据。

应理解，方式一与UE是否注册网络没有关系。也就是说，无论UE是否注册到了网络，或者是否正在发起注册流程，UDM都可以向所述至少一个AMF发送第一信息。
方式二
UDM接收到NEF发送的第一信息后，向特定的AMF发送特定UE的第一信息。
在一个示例中，针对任一UE，若该UE注册完成后，UDM接收到该UE的第一信息，则UDM可以直接向服务该UE的AMF发送该UE的第一信息。比如，UDM可以向AMF发送Nudm_SDM_notification消息，该消息中包括该UE的第一信息。
在另一示例中，针对任一UE，在该UE的注册过程中，服务该UE的AMF可以通过Nudm_SDM_Get流程从UDM获取该UE的第一信息。即，AMF可以向UDM发送一个请求消息，该请求消息可以包括该UE的标识信息，UDM根据该UE的标识信息，若确定存储了该UE的第一信息，则向该AMF发送该UE的第一信息。
可选地，无论是方式一还是方式二，UDM向AMF发送的第一信息可以不包括UE的 标识信息，但本申请对此不作限定。
可选地，无论是方式一还是方式二，UDM向AMF发送的携带第一信息的消息可以包括UE的标识信息，比如Nudm_SDM_notification消息可以携带UE的标识信息，但本申请对此不作限定。
可选地，在S1105之前，该方法还可以包括：UDM从UDR获取签约信息，执行授权检查。若允许AF发起配置请求，则UDM将应用数据作为用户的签约信息存储在UDR中。
S1106，AMF向H-PCF发送第一指示信息。
对应S1105中的方式一，针对所述至少一个AMF中的任一AMF，示例性的，若该AMF接收到的第一信息用于所有的UE，比如该第一信息中不包含UE标识或者群组标识或者第一信息指示用于任意用户，则该AMF可以向与该AMF服务相同UE的H-PCF发送第一指示信息。若该AMF接收到的第一信息为该AMF所服务的某个UE(也可以是多个UE)的第一信息，比如，该第一信息中包含UE标识或者群组标识，且该AMF所服务的该UE的标识为所述UE标识或者为所述群组标识对应的群组成员，则该AMF可以向与该AMF服务相同UE的H-PCF发送该UE的第一指示信息。若该AMF接收到的第一信息不是该AMF所服务的UE的第一信息，则AMF不向与该AMF服务相同UE的H-PCF发送第一指示信息。
对应S1105中的实现方式二，AMF接收到的第一信息就是该AMF所服务的UE的第一信息，因此AMF无需进行判断就可以向与该AMF服务相同UE的H-PCF发送该第一指示信息。
其中，第一指示信息可以指示H-PCF从UDR中获取特定UE的应用数据。第一指示信息可以为DNN。示例性的，若UDM接收到第一信息时，UE已经接入到网络，第一指示信息可以通过Npcf_UEPolicyControlUpdate携带。若UDM接收到第一信息之后，UE才接入到网络，AMF可以在UE策略关联建立流程中向H-PCF提供第一指示信息。
如前所述，位置信息可以包括时间信息和/或位置信息，那么可选地，AMF也可以在位于该位置信息所指示的区域内时，或者在该时间信息所指示的时间内时，向H-PCF发送第一指示信息。
S1107，H-PCF根据第一指示信息，向UDR发送第二请求消息，第二请求消息用于获取所述应用数据。比如，第二请求消息可以包括DNN。
S1108，UDR向H-PCF发送所述应用数据。
S1109至S1111，H-PCF生成UE的策略信息，并通过AMF发送给UE。
应理解，S1109至S1111与S705至S707相同，可以参见S705至S707。
可选地，H-PCF还可以确定PSI和/或PLMN ID，并且可以通过AMF发送给UE。
根据本申请提供的方法，AF可以通过NEF将应用数据及时提供给UDR和UDM，并且UDM通过AMF指示H-PCF从UDR中获取应用数据，从而H-PCF可以获取应用数据，并根据该应用数据生成UE的策略信息，从而能够保证UE可以接入该应用数据对应的业务。
图12是一种策略配置方法的具体示例的流程图。在该方法1200中，第一PCF为H-PCF，第一网元为V-UDR，AF位于V-PLMN中。该方法与方法800的不同之处在于， 该方法中由AMF向V-PCF指示V-PCF从V-UDR中获取应用数据。
S1201至S1205，AF向NEF发送包括所述应用数据业务的配置请求，NEF执行授权检查，检查AF是否被授权执行所述业务的配置请求。若AF被授权执行所述业务的配置请求，NEF向V-UDR发送所述应用数据。NEF向UDM发送第一信息，UDM向AMF发送第一信息。
应理解，S1201至S1205与1101至S1105类似，唯一不同的是，S1203步骤中NEF向V-UDR发送应用数据，而S1103中NEF向UDR(H-UDR)发送应用数据。S1201至S1205具体可以参见S701和S705。
可选地，在S1205之前，该方法还可以包括：UDM从UDR(H-UDR)获取签约信息，执行授权检查。若允许AF发起配置请求，则UDM将应用数据作为用户的签约信息存储在UDR中。
S1206，AMF向V-PCF发送第一指示信息。
示例性的，S1206可以有两种实现方式。这两种实现方式与S1106中描述的AMF向H-PCF发送第一指示信息的方式类似，具体地这里的V-PCF可以对应S1106中的H-PCF。两种方式的具体内容参见上文对S1106所作的说明，这里不再赘述。
S1207，V-PCF向V-UDR发送第二请求消息，第二请求消息用于获取所述应用数据。比如，第二请求消息可以包括DNN。
S1208，V-UDR向V-PCF发送所述应用数据。
S1209，V-PCF向H-PCF发送所述应用数据。
S1210至S1213，H-PCF生成UE的策略信息，并通过V-PCF和AMF发送给UE。
应理解，S1210至S1213与S806至S809相同，可以参见S806至S809。
可选地，H-PCF也可以确定PSI和/或V-PLMN ID，并且可以通过V-PCF和AMF发送给UE。
根据本申请提供的方法，AF可以通过NEF将应用数据及时提供给V-UDR和UDM，并且UDM通过AMF指示H-PCF从V-UDR中获取应用数据，从而H-PCF可以获取应用数据，并根据该应用数据生成UE的策略信息，从而能够保证UE可以接入该应用数据对应的业务。
本申请还提供了一种与方法1200类似的方法，在该方法中，第一PCF为H-PCF，第一网元为V-UDR，AF位于V-PLMN中。该方法与方法1200的不同之处在于，该示例中，V-PCF根据AMF的指示，从V-UDR获取应用数据，并且获得应用数据后，不需要提供给H-PCF，而是自己确定UE的策略信息，并且发送给UE。
因此根据该方法，在漫游场景下，AF可以通过NEF将应用数据及时提供给V-UDR和UDM，并有UDM通过AMF指示V-PCF从V-UDR中获取应用数据，从而V-PCF可以获取应用数据，并根据该应用数据生成UE的策略信息，从而能够保证UE可以接入该应用数据对应的业务。
图13示出了本申请提供的一种策略配置方法1300的示意性流程图。该方法1300可以应用于图2所示的系统200中。
S1301，AF向NEF发送应用数据。
其中，这里应用数据和前述的应用数据所包括的内容相同，这里不再赘述。
示例性的，AF可以通过Nnef_ServiceParameters_create请求消息发送所述应用数据。
S1302，NEF向PCF发送应用数据。
具体地，NEF执行授权检查，检查AF是否被授权发起请求。若AF被授权发起请求，NEF可以选择PCF，如根据UE标识或者群组标识选择PCF。然后，NEF向所选择的PCF发送应用数据，如通过Npcf_dynamicpolicy创建服务消息将应用数据发送给PCF。
S1303，PCF向UDR发送所述应用数据，所述应用数据存储在UDR的UE签约数据中。
示例性的，PCF可以根据UE标识或者群组标识选择UDR，并将应用数据存储在UDR的UE的签约信息中。进一步的PCF在UE签约数据中包含指示信息，所述指示信息用于指示该应用信息为特定网络的应用信息，如所述指示信息包含PLMN ID。后续，服务UE的PCF可以根据该签约信息，生成UE的策略信息。
根据本申请提供的方法，AF通过NEF向PCF动态提供应用数据，进一步的PCF将应用数据存储在UE的策略签约数据中以使得服务UE的PCF获取对应的信息并生成UE策略。
应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定。
