本申请要求于2021年09月30日提交中国专利局、申请号为202111166931.5、申请名称为“数据调用的方法和装置”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
本申请涉及通信技术领域，尤其涉及一种数据调用的方法和装置。
背景技术
《个人信息保护法》以及《General Data Protection Regulation,GDPR》等保护个人信息的法律都对如何保护个人信息提出了要求。例如，如果企业想处理个人信息，需要获取用户的同意。如果用户在授权企业处理自己的个人信息之后，想要撤销用户同意，即撤销授权企业对个人信息的继续处理，企业不应再对个人信息进行处理。
然而，有些请求数据的网络设备不支持撤销用户同意，从而导致用户的撤销权可能无法行使，因此存在法律风险。鉴于此，希望提供一种技术，可以满足用户在网络中行使撤回权的需求。
发明内容
本申请提供了一种数据调用的方法和装置，以便满足用户在网络中行使数据使用的撤回权的需求。
第一方面，提供了一种数据调用的方法，其特征在于，包括：授权验证网元接收来自服务消费网元的数据调用请求消息，该数据调用请求消息包括数据所有者的标识，该数据调用请求消息用于请求调用该数据所有者的数据；该授权验证网元判断该服务消费网元是否具备支持停止处理数据的能力，其中，该能力用于表征该服务消费网元支持停止处理从该授权验证网元获取的数据；在该服务消费网元不具备该能力的情况下，该授权验证网元拒绝该数据调用请求消息。
其中，支持停止处理从授权验证网元获取的数据，可以表示服务消费网元支持在授权验证网元的指示下，停止处理从授权验证网元获取数据，或者说，服务消费网元可以识别授权验证网元发送的通知处理数据的指示信息，并支持根据该指示信息从授权验证网元获取数据。
通过以上方案，授权验证网元根据服务消费网元是否具备支持停止处理数据的能力，从而判断是否可以执行服务消费网元的数据调用请求。如果服务消费网元不具备支持停止处理数据的能力，则授权验证网元拒绝执行服务消费网元的数据调用请求。在该方案的基础上，当终端设备同意了服务消费网元的数据调用后，可以随时行使撤回权，即终端设备可以随时取消同意服务消费网元对数据的调用，可以避免相关法规的风险。
结合第一方面，在第一方面的某些实现方式中，该授权验证网元判断该服务消费网元 是否具备支持停止处理数据的能力，包括：该授权验证网元接收来自该服务消费网元的能力指示信息；响应于该数据调用请求消息，该授权验证网元根据该能力指示信息，确定该服务消费网元是否具备支持停止处理数据的能力。
基于以上方案，授权验证网元根据服务消费网元的能力指示信息确定消费网元是否支持停止处理该数据，从而可以根据服务消费网元是否具备支持停止处理数据的能力，进一步判断是否可以执行服务消费网元的数据调用请求。
结合第一方面，在第一方面的某些实现方式中，该授权验证网元判断该服务消费网元是否具备支持停止处理数据的能力，包括：在该授权验证网元没有接收到来自该服务消费网元的能力指示信息的情况下，或者在该授权验证网元的上下文没有保存该服务消费网元的能力指示信息的情况下，该授权验证网元确定该服务消费者不具备支持停止处理数据的能力，该能力指示信息用于指示该服务消费网元是否具备该能力。
一种实现方式，如果服务消费网元具备支持停止处理数据的能力，则服务消费网元在发送数据调用请求消息之前，上报能力指示信息，该能力指示信息用于指示该服务消费网元具备支持停止处理数据的能力。授权验证网元可以根据该能力指示信息确定服务消费网元支持停止处理该数据；如果授权验证网元没有接收到该能力指示信息，则授权验证网元确定该服务消费网元不支持停止处理该数据。
另一种实现方式，该授权验证网元向该服务消费网元发送能力信息查询请求消息，该能力信息查询请求消息用于请求查询该服务消费网元是否支持停止处理该数据。如果服务消费网元支持停止处理数据，则服务消费网元向该授权验证网元上报能力指示信息，该能力知识性信息用于指示该服务消费网元支持停止处理个人数据。授权验证网元可以根据该能力指示信息确定该服务消费者支持停止处理该数据；如果授权验证网元在发送了该能力信息查询请求消息之后，没有在设定的时间内接收到该服务消费网元上报的能力指示信息，则授权验证网元确定该服务消费网元不支持停止处理该数据。
基于以上方案，授权验证网元可以灵活判断该服务消费网元是否支持停止处理该终端设备的数据，从而可以根据判断结果判断是否可以执行服务消费网元的数据调用请求。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：该授权验证网元向该服务消费网元发送能力信息查询请求消息，该能力信息查询请求消息用于请求查询该服务消费网元是否具备该能力。
基于以上方案，授权验证网元可以通过能力信息查询请求消息，确定服务消费网元是否具备停止数据处理的能力，从而可以根据服务消费网元是否具备该能力判断是否处理服务消费网元的数据请求。
结合第一方面，在第一方面的某些实现方式中，该授权验证网元拒绝该服务消费网元的该数据调用请求消息，包括：该授权验证网元向该服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝该数据调用请求消息，该数据调用响应消息包括原因值，该原因值用于指示拒绝该数据调用请求消息的原因。作为一种示例，该原因值用于指示拒绝的原因为该服务消费网元不支持该能力。
基于以上方案，当服务消费网元不具备支持停止处理数据的能力，则授权验证网元向服务消费网元发送用于拒绝数据调用的响应消息，并通过原因值向服务消费网元指示拒绝的原因。这样可以使得服务消费网元确定被拒绝的原因，从而不再发起数据调用，节省资 源。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：该授权验证网元确定该数据所有者允许该服务消费网元使用该数据所有者的数据。
基于以上方案，数据验证网元可以在确定了数据所有者允许服务消费网元使用该数据所有者的数据的情况下，再验证服务消费网元是否具备支持停止数据处理的能力。当数据所有者允许服务消费网元使用该数据所有者的数据，且服务消费网元支持停止数据处理的能力，则数据验证网元才执行服务消费网元的数据调用请求，从而保证服务消费网元的数据调用请求得到了用户同意，且用户可以行使撤回权。
结合第一方面，在第一方面的某些实现方式中，该授权验证网元确定该数据所有者允许该服务消费网元使用该数据所有者的数据，包括：该授权验证网元向存储网元发送意向验证请求消息，该意向验证请求消息包括该数据所有者的标识，该意向验证请求消息用于请求验证所述数据所有者是否允许该服务消费网元使用该数据所有者的数据；该授权验证网元从存储网元接收意向验证响应消息；该授权验证网元根据该意向验证响应消息确定该数据所有者允许该服务消费网元使用该数据所有者的数据。

基于上述方案，服务消费网元可以根据授权验证网元发送的数据调用响应消息，获取授权验证网元拒绝的原因值。从而可以进一步根据原因值确定是否可以重新请求调用数据所有者的数据。
结合第二方面，在第二方面的某些实现方式中，该方法还包括：根据所述原因值，所述服务消费网元确定不再向所述授权验证网元请求获取数据。
基于上述方案，服务消费网元可以根据原因值确定是否再向授权验证网元请求获取数据。作为一种示例，当原因值指示拒绝的原因为服务消费网元不具备停止处理数据的能力，则服务消费网元确定不再向所述授权验证网元请求获取数据。
结合第二方面，在第二方面的某些实现方式中，该方法还包括：该服务消费网元接收来自该授权验证网元的能力信息查询请求消息，该能力信息查询请求消息用于请求查询该服务消费网元是否具备支持停止处理数据的能力；响应于该能力信息查询请求消息，该服务消费网元向该授权验证网元发送能力指示信息，该能力指示信息用于指示该服务消费网元是否具备该能力。
基于上述方案，服务消费网元可以根据授权验证网元的能力信息查询请求，上报能力指示信息，以指示该服务消费网元是否支持停止处理终端设备的数据，从而使得授权验证网元可以根据该服务消费网元是否支持停止处理该终端设备的数据，决定是否执行服务消费网元的数据调用请求。

应理解，上述应用于本申请实施例的网络架构仅是一种举例说明，适用本申请实施例的网络架构并不局限于此，任何能够实现上述各个网元的功能的网络架构都适用于本申请实施例。
例如，在某些网络架构中，AMF、SMF网元、PCF网元、BSF网元以及UDM网元等网络功能网元实体都称为网络功能(network function，NF)网元；或者，在另一些网络架构中，AMF，SMF网元，PCF网元，BSF网元，UDM网元等网元的集合都可以称为控制面功能网元。
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的说明本申请实施例的技术方案，并不构成对于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。

示例性地，该NF服务消费者也可以称为NF consumer，该NF服务消费者例如可以是AF、PCF等请求分析数据的网元。NF服务消费者向NWDAF发送数据调用请求(Nnwdaf_AnalyticsSubscription_Subscribe Request)消息。该消息中包括用户设备的标识(例如用户设备的SUPI)以及分析标识(Analytics ID)，该分析标识用于指示当前的分析，例如该分析标识用于标识用户设备的移动性分析(UE mobility Analytics)，又例如，该分析标识用于标识用户设备的通信分析(UE communication Analytics)等。
202，NWDAF判断是否需要校验用户意向。
示例性地，NWDAF接收来自NF服务消费者的数据调用请求消息之后，根据本地策略判断本次数据调用是否需要校验用户意向，即判断是否需要检验用户是否同意本次数据调用。
例如，NWDAF根据本地策略判断本次调用是否涉及对用户个人数据的操作，如果涉及的话，则NWDAF确定需要对本次调用校验用户意向，如果不涉及的话，则NWDAF确定不需要对本次调用校验用户意向。
在本次数据调用需要校验用户意向的情况下，NWDAF可以通过UDM获取校验结果。示例性地：
203，NWDAF向UDM发送签约信息请求消息。
示例性地，NWDAF向UDM发送签约信息请求(Nudm_SDM_Get Request)消息，该签约信息请求消息用于请求获取用户设备的签约信息，该请求消息中包括该用户设备的标识(例如该用户设备的SUPI)。
204，UDM获取用户签约信息。
示例性地，UDM接收到来自NWDAF的签约信息请求消息，然后根据该签约信息请求消息中携带的用户设备的标识，获取该用户设备的签约信息。该签约信息包括操作指示和用户意向指示。
其中，该数据操作指示用于指示对数据的操作，该数据操作指示的具体形式可以是API名称，可选的，还可以加上API输入。用户意向指示用于指示用户是否同意数据操作指示对于数据的操作。例如，用户意向指示为1，则表示用户同意数据操作指示对于数据的操作；又例如，用户意向指示为0，则标识用户不同意数据操作指示对于数据的操作。
可选的，该签约信息中还可以包括数据处理者的标识。该数据处理者的标志可以是PLMN ID，AS ID等。
若签约信息中包括数据处理者的标识，则用户意向指示用于指示是否同意数据处理者对数据执行数据操作指示所对应的操作。
205，UDM向NWDAF发送签约信息响应消息。
示例性地，UDM获取到用户签约信息之后，向NWDAF发送签约信息响应(Nudm_SDM_Get Response)消息，该签约信息响应消息中包括用户意向指示和数据操作指示，可选的还包括数据处理者的标识。
206，NWDAF确定用户意向。
示例性地，NWDAF接收来自UDM的签约信息响应消息，然后根据该签约信息响应消息中携带的信息，判断用户是否同意数据操作指示对应的操作。例如，NWDAF从签约信息响应消息中携带的数据操作指示和用户意向指示，查找与步骤201的数据调用请求消息中携带的分析标识相对应的数据操作所对应的用户意向，若该用户意向为同意，则表示用户同意分析标识所对应的操作；若用户意向为不同意，则标识用户不同意分析标识所对应的操作。
207，NWDAF向UDM发送签约信息订阅请求消息。
示例性地，如果NWDAF确定用户意向为用户同意数据操作指示对应的操作，则NWDAF向UDM发送签约信息订阅请求(Nudm_SDM_Subscribe Request)消息，该签约 信息请求消息中包括用户设备的标识(例如用户设备的SUPI)。可选的，该签约信息请求消息中还包括用于设备的签约类型，该签约类型用于指示用户设备同意的签约类型。该签约信息请求消息用于请求订阅签约信息变更事件。当订阅成功之后，一旦用户设备的签约信息发生改变，UDM将通知NWDAF。
208，UDM向NWDAF发送签约信息订阅响应消息。
示例性地，UDM接收到来自NWDAF的签约信息订阅请求消息之后，向NWDAF发送签约信息订阅响应(Nudm_SDM_Subscribe Reponse)消息，该签约信息订阅响应消息用于指示订阅签约信息变更事件成功。
209，NWDAF向NF服务消费者发送数据调用响应消息。
示例性地，如果步骤206中，NWDAF确定用户意向为不同意数据操作指示对应的操作，则NWDAF可以跳过步骤207至步骤208，直接向NF服务消费者发送数据调用响应(Nnwdaf_AnalyticsSubscription_Subscribe Response)消息，该数据调用响应消息用于指示数据调用请求失败。
如果在步骤206中，NWDAF确定用户意向为同意数据操作指示对应的操作，则NWDAF向NF服务消费者发送数据调用响应(Nnwdaf_AnalyticsSubscription_Subscribe Response)消息，该数据调用响应消息用于指示数据调用请求成功。
210，NWDAF向NF服务提供者发送用户数据请求消息。
示例性地，如果NWDAF确定用户意向为同意数据操作指示对应的操作，则NWDAF可以向NF服务提供者(NF consumer)发送用户数据请求消息，该用户数据请求消息包括用户设备的标识(例如用户设备的SUPI)，该用户数据请求消息用于请求获取该用户设备的用户数据。
211，NF服务提供者向NWDAF发送用户数据响应消息。
示例性地，NF服务提供者接收到来自NEWDAF的用户数据请求消息之后，向NWDAF发送用户数据响应(Nnf_EventExposure_Notify)消息，该用户数据响应消息中包括NWDAF请求的用户数据。一种实例，这里的NF服务提供者为AMF，这里的用户数据为用户设备的位置数据(如TAI等)；又一示例，这里的NF服务提供者为SMF，这里的用户数据为用户设备的通信数据(例如通信间隔、通信速率等)。
212，NWDAF向NF服务消费者发送数据分析通知消息。
示例性地，NWDAF从来自NF服务提供者的用户数据响应消息中获取用户数据，并按照服务消费者请求的分析(步骤201中数据调用请求消息携带的分析标识所指示的分析)，对该用户数据进行分析处理，获得分析结果。该分析结果例如可以包括用户设备的位置统计信息，或者用户设备的通信特征信息。
进一步的，NWDAF向NF服务消费者发送数据分析通知(Nnwdaf_AnalysisSubscription_Notify)消息，该数据分析通知消息中包括分析结果。
213，UDM更新用户签约信息。
示例性地，当步骤204中的用户签约信息中的用户意向指示为用户设备同意数据操作指示对应的操作，但此时用户希望行使撤回权，即用户设备不再同意数据操作指示对应的操作，此时会导致用户签约信息的变更。例如，用户设备不再同意对其移动性进行分析，则签约信息中的分析标识为用户设备移动性分析(UE mobility Analytics)对应的数据操作 对应的用户意向变更为“不同意”。对应的，UDM更新用户签约信息。
214，UDM向NWDAF发送签约信息变更通知消息。
示例性地，由于NWDAF订阅了签约信息变更事件，因此在UDM更新了用户签约信息之后，UDM向NWDAF发送签约信息变更通知消息，该签约信息变更通知消息中携带变更后的签约信息。
215，NWDAF向NF服务消费者发送数据调用通知消息。
示例性地，NWDAF接收到UDM发送的签约信息变更通知消息，且根据该签约信息变更通知消息中携带的签约信息确定用户设备不再同意数据操作指示对应的操作，则NWDAF向NF服务消费者发送数据调用通知(Nnwdaf_AnalyticsSubscription_Notify)消息，该数据调用通知消息包括终止指示(Termination Request)，该终止指示用于指示NF服务消费者终止对用户数据进行处理。
216，NF服务消费者向NWDAF发送数据调用去订阅通知消息。
示例性地，NF服务消费者接收到来自NWDAF发送的数据调用通知消息之后，根据该数据调用通知消息中的终止指示终止对用户数据进行处理，并向NWDAF发送数据调用去订阅通知消息，用于去订阅步骤201的分析事件。
然而在上述方案中，如果NF服务消费者不支持停止数据处理，则用户便无法行使撤回权，同时可能存在法律风险。
图3示出了本申请实施例提供的数据调用的方法300的示例性流程图。该方法300包括：
301，服务消费网元向授权验证网元发送数据调用请求消息。
示例性地，该数据调用请求消息包括数据所有者的标识，该数据调用请求消息用于请求调用该数据所有者的数据，或者说，该数据调用请求消息用于请求对该数据所有者的数据进行处理。该数据所有者例如可以是终端设备，或者是其他存有数据的网元。
可选的，该数据调用请求消息中还可以包括操作指示，该操作指示用于指示该服务消费网元对该数据所有者的数据的具体操作，例如收集、读取、分析、共享等。
应理解，这里的服务消费网元可以是各种请求数据或请求服务的网元，该名称仅仅是一种示例，并不对该网元的功能或特性造成任何限定。例如，该服务消费网元还可以称为数据使用网元、数据请求网元、数据使用者等。具体地，在5G系统中，该服务消费网元可以是AF、PCF等请求分析数据的网元。
302，授权验证网元判断服务消费网元是否具备支持停止处理数据的能力。
示例性地，授权验证网元接收来自服务消费网元的数据调用请求消息之后，判断服务消费网元是否具备支持停止处理数据的能力。其中，具备支持停止处理数据的能力用于表征服务消费网元支持停止处理从授权验证网元获取的数据。
其中，支持停止处理从授权验证网元获取的数据，可以表示服务消费网元支持在授权验证网元的指示下，停止处理从授权验证网元获取数据，或者说，服务消费网元可以识别授权验证网元发送的通知处理数据的指示信息，并支持根据该指示信息从授权验证网元获取数据。
支持停止处理从授权验证网元获取的数据，可以用于表征服务消费网元支持停止通过授权验证网元调用数据，和/或该服务消费网元支持删除通过授权验证网元获取的数据。
下面对授权验证网元判断服务消费网元是否具备支持停止处理数据的能力的几种可能的实现方式作示例性说明。
一种实现方式，服务消费网元向授权验证网元上报自己的能力指示信息，该能力指示信息用于指示该服务消费网元是否具备支持停止处理该数据的能力，即该能力指示信息用于指示该服务消费网元支持停止处理数据，或者该指示信息用于指示该服务消费网元不支持停止处理数据。该能力指示信息可以承载于上述数据调用请求消息中，也可以承载于该数据调用请求消息之前的任意消息中。授权验证网元接收到服务消费网元的能力指示信息之后，可以将该能力指示信息保存到上下文中，该能力指示信息与该服务消费网元的标识相关联。授权验证网元可以根据该服务消费网元的能力指示信息确定该服务消费网元是否具备支持停止处理数据的能力。
另一种实现方式，当服务消费网元具备支持停止处理数据的能力时，服务消费网元向该授权验证网元上报具备支持停止处理数据的能力的指示信息，该指示信息可以承载于上述数据调用请求消息中，也可以承载于该数据调用请求消息之前的任意消息中。授权验证网元接收到该指示信息之后，可以将该指示信息保存到上下文。一种情况，授权验证网元接收来自服务消费网元的数据调用请求消息，如果该消息中携带了具备支持停止处理数据的能力的指示信息，或者授权验证网元从上下文中获取到了与该服务消费网元携带标识相关联的具备支持停止处理数据的能力的指示信息，则授权验证网元确定该服务消费网元支持停止处理该数据所有者的数据；另一种情况，授权验证网元接收来自服务消费网元的数据调用请求消息，如果该消息中没有携带具备支持停止处理数据的能力的指示信息，授权验证网元从上下文中也没有获取到与该服务消费网元的标识相关联的具备支持停止处理数据的能力的指示信息，则授权验证网元确定该服务消费网元不支持停止处理该数据所有者的数据。
又一种实现方式，授权验证网元接收到来自服务消费网元的数据调用请求消息之后，该授权验证网元向该服务消费网元发送能力信息查询请求消息，该能力信息查询请求消息用于请求查询该服务消费网元是否支持停止处理数据所有者的数据。一种情况，服务消费网元接收来自授权验证网元的能力信息查询请求消息，然后服务消费网元向该授权验证网元发送能力信息查询响应消息，该能力信息查询响应消息包括能力指示信息，该能力指示信息用于指示该服务消费网元是否支持停止处理数据所有者的数据。对应地，授权验证网元接收来自服务消费网元的能力查询响应消息，然后根据该响应消息中携带的能力指示信息确定该服务消费网元是否具备支持停止处理数据的能力。另一种情况，服务消费网元接收来自授权验证网元的能力信息查询请求消息，如果该服务消费网元具备支持停止处理数据的能力，则服务消费网元向该授权验证网元发送能力信息查询响应消息，该能力信息查询响应消息包括具备支持停止处理数据的能力的指示信息。对应地，授权验证网元接收来自服务消费网元的能力信息查询响应消息，然后根据该响应消息中携带的指示信息，确定该服务消费网元具备支持停止处理数据的能力；如果该服务消费网元不具备支持停止处理数据的能力，则服务消费网元可以不做回复。授权验证网元在向服务消费网元发送了能力信息查询请求消息之后，如果在设定的时间内没有接收到来自服务消费网元的响应消息，则授权验证网元确定该服务消费网元不具备支持停止处理数据的能力。
303，授权验证网元向服务消费网元发送数据调用响应消息。
示例性地，如果授权验证网元确定服务消费网元不具备支持停止处理数据的能力，则服务消费网元拒绝该服务消费网元的数据调用请求。例如，授权验证网元向服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝该数据调用请求消息，该数据调用响应消息包括原因值，该原因值用于指示拒绝该数据调用请求消息的原因。作为一种示例，该原因值用于指示拒绝的原因为该服务消费网元不具备支持停止处理数据的能力。对应地，服务消费网元接收该数据调用响应消息，根据该响应消息中携带的原因值，服务消费网元确定不再向该授权验证网元请求获取该数据所有者的数据，或者，该服务消费网元确定不再向授权验证网元请求获取任意数据所有者的数据，或者，该服务消费网元确定不再向授权验证网元请求获取任意数据所有者的涉及用户隐私的数据。
示例性地，如果授权验证网元确定服务消费网元具备支持停止处理数据的能力，则进一步的，服务消费网元通过存储网元验证该数据所有者是否允许该服务消费网元使用该数据所有者的数据。例如，授权验证网元向存储网元发送意向验证请求消息，该意向验证请求消息包括该数据所有者的标识，该意向验证请求消息用于请求验证该数据所有者是否允许该服务消费网元使用该数据所有者的数据，或者说该意向验证请求消息用于请求验证该数据所有者是否允许该服务消费网元对该数据所有者的数据进行处理。对应地，存储网元接收来自服务消费网元的意向验证请求消息，根据该意向验证请求消息，该存储网元获取该数据所有者的签约信息，存储网元根据该签约信息判断数据所有者是否允许该服务消费网元使用该数据所有者的数据。然后存储网元向授权验证网元发送意向验证响应消息，该意向验证响应消息用于响应于意向验证请求消息，该意向验证响应消息用于指示该数据所有者是否允许该服务消费网元使用该数据所有者的数据。对应地，授权验证网元接收该意向验证响应消息，并根据该意向验证响应消息确定该数据所有者是否允许该服务消费网元使用该数据所有者的数据。
如果数据所有者不允许服务消费网元使用该数据所有者的数据，则授权验证网元向服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝服务消费网元的数据调用请求，该数据调用响应消息携带原因值，该原因值用于指示拒绝的原因为数据所有者不允许服务消费网元使用该数据所有者的数据；如果数据所有者允许服务消费网元使用该数据所有者的数据，则授权验证网元向服务提供网元请求获取数据所有者的数据。
应理解，授权验证网元在接收到来自服务消费网元的数据调用请求消息之后，也可以先验证该数据所有者是否允许服务消费网元使用该数据所有者的数据。当数据所有者不允许服务消费网元使用该数据所有者的数据，则授权验证网元拒绝服务消费网元的数据调用请求，可以不再验证服务消费网元是否具备支持停止处理数据的能力；当数据所有者允许服务消费网元使用该数据所有者的数据，则授权验证网元再进一步判断服务消费网元是否具备支持停止处理数据的能力。
在另一种可能的实现方式中，授权验证网元在接收到来自服务消费网元的数据调用请求消息之后，验证在服务消费网元不具备支持停止处理数据的能力的情况下，数据所有者是否允许服务消费网元使用该数据所有者的数据。如果服务消费网元不具备支持停止处理数据的能力的情况下，数据所有者仍然允许服务消费网元使用该数据所有者的数据，则授权验证网元可以不必再验证服务消费网元是否具备支持停止处理数据的能力，直接执行后续流程。
通过以上方案，授权验证网元根据服务消费网元是否具备支持停止处理数据的能力，从而判断是否可以执行服务消费网元的数据调用请求。如果服务消费网元不具备支持停止处理数据的能力，则授权验证网元拒绝执行服务消费网元的数据调用请求。在该方案的基础上，数据所有者即使是在允许了服务消费网元使用该数据所有者的数据之后，也可以随时行使撤回权，即数据所有者可以随时取消允许服务消费网元对数据所有者的数据的调用，可以避免相关法规的风险。
图4示出了本申请实施例提供的数据调用的方法400的示例性流程图。该方法400包括：
401，服务消费网元向授权验证网元发送支持停止数据处理能力的指示信息#1。
示例性地，该指示信息#1用于指示服务消费网元具备支持停止处理用户数据的能力，该支持停止处理数据的能力，用于表征服务消费网元支持停止处理从授权验证网元获取的数据。具体地，该支持停止处理数据的能力可以表示服务消费网元支持在授权验证网元的指示下，停止处理该授权验证网元获取的数据。
该支持停止处理用户数据例如可以包括支持撤销对用户数据的调用，和/或删除已经获取的个人数据等。服务消费网元具备支持停止数据处理的能力，表示服务消费网元可以根据数据校验者的指示停止处理个人数据，具体实现方式可参见步骤420。这里的用户数据代表可识别的自然人的相关信息，或者说用户的个人数据信息。
应理解，服务消费网元应在请求调用用户数据之前，向授权验证网元发送该支持停止数据处理能力的指示信息#1。例如，服务消费网元可以在与授权验证网元建立连接的过程，向授权验证网元发送该支持停止数据处理能力的指示信息#1。又例如，当服务消费网元希望对用户数据进行处理(或者说当服务消费网元希望调用用户数据)，且该服务消费网元具备支持停止数据处理的能力，则服务消费网元可以在请求调用用户数据之前，向授权验证网元发送支持停止数据处理能力的指示信息#1。
还应理解，当服务消费网元不具备支持停止数据处理的能力时，服务消费网元也可以向授权验证网元指示其不支持停止数据处理。例如，服务消费网元可以采用预留值来指示停止数据处理的能力，当预留值为0，表示服务消费网元不具备支持停止数据处理的能力，当预留值为1，表示服务消费网元具备支持停止数据处理的能力。
应理解，这里的服务消费网元可以是基于服务化接口进行通信的双方中，请求服务的一方，该服务消费网元也可以称为数据使用网元、数据使用者、请求端、数据请求网元等，该服务消费网元例如可以是AF、PCF等请求分析数据的网元。这里的授权验证网元也可以称为授权验证网元、授权校验网元等，该授权验证网元可以是NWDAF、NEF、DCCF等用于进行数据分析的网元。应理解，服务消费网元不同的数据分析需求可能对应不同的授权验证网元。
402，授权验证网元保存支持停止数据处理能力指示信息#1到上下文。
示例性地，授权验证网元接收来自服务消费网元的支持停止数据处理能力指示信息#1后，将该支持停止数据处理能力指示信息#1保存到上下文中。该支持停止数据处理能力指示信息#1与该服务消费网元的标识相关联。
403，可选的，授权验证网元向服务消费网元发送响应消息。
示例性地，该响应消息可以包括ACK，以指示授权验证网元成功接收支持停止数据 处理能力指示信息#1。可选的，该响应消息还可以包括支持停止数据处理能力指示信息#2，该支持停止数据处理能力指示信息#2用于指示授权验证网元具备支持停止处理个人数据的能力。授权验证网元具备支持停止处理个人数据的能力，表示授权验证网元可以通知服务消费网元停止处理个人数据，具体实现方式参见步骤419。
404，服务消费网元向授权验证网元发送数据调用请求消息。
示例性地，服务消费网元向授权验证网元发送数据调用请求消息，该数据调用请求消息用于请求对用户数据进行操作。该数据调用请求消息包括用户设备的标识#1，该用户设备的标识#1可以是用户设备的SUPI、GPSI等，此处不做限定。
可选的，该数据调用请求消息还可以包括数据调用标识，该数据调用标识可以指示对用户数据的具体操作，例如对用户数据进行收集、读取、分析、共享等。
该数据调用标识的具体形式可以是API名称，例如Nnef_Location、Nnef_UEIdentifier_Get、Nnwdaf_AnalyticsSubscription_Subscribe等。
一种示例，服务消费网元为某应用的应用服务器AS，授权验证网元为NEF，AS调用NEF开放的，请求UE标识的API(例如Nnef_UEIdentifier_Get，其输入user information可以设置为某个UE的IP地址)，即此时数据调用标识为Nnef_UEIdentifier_Get，该操作代表AS请求获取输入的IP地址对应的用户的标识信息，则调用该API的数据调用请求消息指示AS对用户个人数据(即身份信息)采取读取的操作。
另一种示例，服务消费网元为PCF，授权验证网元为NWDAF，PCF调用NWDAF提供数据分析的API，并提供用户设备的位置，例如Nnwdaf_AnalyticsSubscription_Subscribe，其输入analytics ID设置为UE mobility analytics，Target of Analytics Reporting设置为某个UE的SUPI，其中，该analytics ID即上述数据调用标识，数据调用标识设置为UE mobility analytics，表示PCF请求NWDAF对用户设备的移动性数据进行分析。
应理解，步骤404和步骤401可以合并发送，即401中的支持停止数据处理能力指示信息#1可以承载于404的数据调用请求消息中，即服务消费网元可以在发送数据调用请求消息的同时，上报支持停止数据处理能力指示信息#1。
405，授权验证网元判断是否需要校验用户意向。
示例性地，授权验证网元接收来自服务消费网元的数据调用请求消息之后，根据本地策略判断本次数据调用是否需要校验用户意向(或者说校验用户同意结果)，即判断是否需要校验用户是否允许服务消费网元使用该用户的数据。
例如，授权验证网元根据本地策略判断本次调用是否涉及对用户个人数据的操作，如果涉及的话，则授权验证网元确定需要针对本次调用校验用户意向；如果不涉及的话，则授权验证网元确定不需要针对本次调用校验用户意向。
如果需要针对本次数据调用校验用户，则授权检验者对本次数据调用校验用户意向，或者说授权验证网元判断用户是否同意对用户数据执行相应的操作，或者说授权验证网元验证用户是否允许服务消费网元使用该用户的数据。下面对两种可能的实现方式作示例性说明。
一种可能的实现方式(记为方案1)中，授权验证网元从存储网元获取用户签约信息，然后根据用户签约信息判断用户意向。例如：
406，授权验证网元向存储网元发送签约信息请求消息。
示例性地，该签约信息请求消息包括用户设备的标识#2，该签约信息请求消息用于请求获取用户设备的签约信息。应理解，该用户设备的标识#2可以是与用户设备的标识#1相同的标识，也可以是由用户设备的标识#1转化得到的标识，本申请不做限定。例如，该用户设备的标识#1为用户设备的GPSI，该用户设备的标识#2为SUPI，该SUPI是根据该GPSI转化得到的。
407，存储网元获取用户签约信息。
示例性地，存储网元接收到来自授权验证网元的签约信息请求消息，然后根据该签约信息请求消息中携带的用户设备的标识#2，获取该用户设备的签约信息，或者说获取与该用户设备的标识#2相对应的签约信息。该签约信息包括数据操作指示，以及和该数据操作指示所对应的用户意向指示。
该数据操作指示用于指示对数据的操作，该数据操作指示的具体形式可以是API名称，可选的，还可以加上API输入。用户意向指示也可以称为用户同意结果，用于指示用户是否同意数据操作指示对于数据的操作。例如，用户意向指示为1，则表示用户同意数据操作指示对于数据的操作；又例如，用户意向指示为0，则标识用户不同意数据操作指示对于数据的操作。
可选的，该签约信息中还可以包括数据处理者的标识。该数据处理者的标志可以是PLMN ID，AS ID等。若签约信息中包括数据处理者的标识，则用户意向指示用于指示是否同意数据处理者对数据执行数据操作指示所对应的操作。
408，存储网元向授权验证网元发送签约信息响应消息。
示例性地，该签约信息响应消息包括用户设备的签约信息，该签约信息包括数据操作指示，以及数据操作指示所对应的用户意向指示，可选的还包括数据处理者的标识。
对应的，授权验证网元接收来自存储网元的签约信息响应消息，根据该签约信息响应消息中携带的签约信息判断用户设备是否同意执行数据调用标识所指示的操作。
示例性地，授权验证网元从签约信息响应消息中获取用户设备的签约信息，根据该签约信息确定数据调用标识指示的操作所对应的用户意向。例如，授权检验者在数据操作指示对应的操作中找到与数据调用标识所对应的操作，然后获取该操作所对应的用户意向指示。可选的，如果签约信息中还包括数据处理者的标识，授权验证网元还可以根据数据调用标识所对应的操作获取对应的数据处理者的标识，验证该数据处理者的标识是否包括服务消费网元的标识。
另一种可能的实现方式(记为方案2)中，授权验证网元请求存储网元判断用户意向。例如：
409，授权验证网元向存储网元发送用户意向验证请求消息。
示例性地，该用户意向验证请求消息包括用户设备的标识#2，以及数据调用标识。可选的，该用户意向验证请求消息中还包括数据处理者的标识。该用户意向验证请求消息用于请求验证该数据调用标识指示的操作所对应的用户意向，或者说，该用户意向验证请求消息用于请求验证用户是否同意执行该数据调用标识所指示的操作。
应理解，该用户设备的标识#2可以是与用户设备的标识#1相同的标识，也可以是由用户设备的标识#1转化得到的标识，本申请不做限定。例如，该用户设备的标识#1为用户设备的GPSI，该用户设备的标识#2为SUPI，该SUPI是根据该GPSI转化得到的。应 理解，该数据调用标识是数据调用请求消息中携带的、指示服务消费网元请求对数据的具体操作的标识。
410，存储网元根据用户签约信息确定用户意向。
示例性地，存储网元接收来自授权验证网元的用户意向验证请求消息，并根据该用户意向验证请求消息中携带的用户设备的标识#2，获取该用户设备的签约信息。
进一步的，存储网元根据该用户设备的签约信息确定数据调用标识指示的操作所对应的用户意向，或者说授权存储网元根据该用户设备的签约信息确定用户设备是否同意执行该数据调用标识所指示的操作。例如，存储网元在数据操作指示对应的操作中找到与数据调用标识所对应的操作，然后确定该操作所对应的用户意向。可选的，如果签约信息中还包括数据处理者的标识，存储网元还可以根据数据调用标识所对应的操作获取对应的数据处理者的标识，验证该数据处理者的标识是否包括该服务消费网元的标识。
411，存储网元向授权验证网元发送用户意向验证响应消息。
示例性地，该用户意向验证响应消息包括用户意向指示信息，该用户意向指示信息用于指示用户设备是否同意对用户数据执行数据调用标识所对应的操作。
对应的，授权验证网元接收来自存储网元的用户意向验证请求消息，并根据该用户意向验证请求消息中携带的用户意向指示确定数据调用指示所对应的用户意向。
如果用户意向指示用户不同意对用户数据执行相应操作，则在413，授权验证网元向服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝服务消费网元的数据调用请求消息。
412，授权验证网元判断服务消费网元是否支持停止数据处理。
示例性地，如果用户意向指示用户同意对用户数据执行相应操作，则授权验证网元进一步判断服务消费网元是否支持停止数据处理，或者说是否具备支持停止数据处理的能力。
例如，授权验证网元根据本地上下文判断服务消费网元是否具备支持停止数据处理的能力。具体的，
授权验证网元根据服务消费网元的标识在本地上下文查找与该服务消费网元的标识对应的支持停止数据处理能力指示信息#1。如果上下文中存在该指示信息#1，则授权验证网元确定该服务消费网元具备支持停止数据处理的能力。如果上下文中没有该能力信息#1，则授权验证网元确定服务消费网元不具备支持停止数据处理的能力，或者说服务消费网元不支持停止数据处理。
应理解，授权验证网元可以先确定用户意向，再确定服务消费网元是否具备停止数据处理的能力，也可以先确定服务消费网元是否具备数据处理的能力，再确定用户意向，本申请不做限定。
即，步骤412也可以在方案1或方案2之前执行。在这种实现方式中，如果授权验证网元根据405的判断结果确定本次数据调用需要校验用户意向，则授权验证网元先判断服务消费网元是否具备支持停止数据处理的能力，具体判断方式可以参见步骤412，不再赘述。此时，如果服务消费网元不具备支持停止数据处理的能力，则授权验证网元可以跳过步骤406至408，或步骤409至411，直接执行步骤413，即向服务消费网元发送数据调用响应消息，以拒绝服务消费网元的数据调用请求消息。
在一种可能的实现方式中，如果服务消费网元不具备支持停止数据处理的能力，则服 务消费网元可以在步骤404之前或者同时，上报不支持停止数据处理能力指示信息。对应的，授权验证网元在收到服务消费网元上报的不支持停止数据处理能力指示信息之后，将该不支持停止数据处理能力指示信息保存到上下文，并与该服务消费网元的标识相关联。在这种情况下，授权验证网元根据本地上下文判断服务消费网元是否具备支持停止数据处理能力，还可以包括：如果本地上下文存有与该服务消费网元的标识相关联的不支持停止数据处理能力指示信息，则授权验证网元确定该服务消费网元不具备支持停止数据处理的能力，或者说服务消费网元不支持停止数据处理，此时授权验证网元向服务消费网元发送数据调用响应消息，以拒绝服务消费网元的数据调用请求消息。
如果授权验证网元确定用户同意对用户数据执行数据调用标识所对应的操作，且服务消费网元支持停止数据处理，则授权验证网元根据数据调用请求消息向服务提供网元请求获取用户数据。示例性地：
414，授权验证网元向服务提供网元发送用户数据请求消息。
示例性地，该用户数据请求消息用于请求数据调用请求所需要的用户数据。
应理解，这里的服务提供网元可以是基于服务化接口进行通信的双方中，提供服务的一方，该服务消费网元也可以称为数据提供网元、数据提供者、服务提供者、生产者等。该服务提供网元例如可以是AMF、SMF等提供数据的网元。
415，服务提供网元向授权验证网元发送用户数据#1。
示例性地，服务提供网元接收来自授权验证网元的用户数据请求消息，然后根据该请求消息向授权验证网元发送用户数据#1。
416，授权验证网元向服务消费网元发送用户数据#2。
示例性地，授权验证网元接收来自服务提供网元的用户数据#1，然后根据数据调用标识所对应的操作对用户数据#1进行处理，得到用户数据#2。
例如，服务消费网元为应用服务器AS，授权验证网元为NEF，AS调用NEF开放的、用于请求用户设备标识的API(例如Nnef_UEIdentifier_Get，其输入user information设置为某个用户设备的IP地址)，则在该示例中，用户数据#1和用户数据#2都可以是请求的IP地址对应的用户的标识信息。
又例如，服务消费网元为PCF，授权验证网元为NWDAF，PCF调用NWDAF提供的数据分析的API，并提供分析UE位置(例如Nnwdaf_AnalyticsSubscription_Subscribe，其输入analytics ID设置为UE mobility analytics，Target of Analytics Reporting设置为某个用户设备的SUPI)，则在该示例中，用户数据#1为UE的位置信息，用户数据#2为根据UE的位置信息得出的分析结果。
417，UDM更新用户签约信息。
示例性地，如果用户想要将对用户数据的处理意向由同意修改为不同意，或者说用户想要取消同意对用户数据的处理，或者说用户不再同意服务消费网元使用该用户的数据，此时会导致用户签约信息的变更。例如，用户设备不再同意对其移动性进行分析，则签约信息中的分析标识为用户设备移动性分析(UE mobility Analytics)对应的数据操作对应的用户意向变更为“不同意”。对应的，UDM更新用户签约信息。
418，存储网元向授权验证网元发送签约信息变更通知消息。
示例性地，存储网元向授权验证网元发送签约信息变更通知消息，该签约信息变更通 知消息中携带变更后的签约信息。
419，授权验证网元向服务消费网元发送数据调用通知消息。
示例性地，授权验证网元接收到存储网元发送的签约信息变更通知消息，且根据该签约信息变更通知消息中携带的签约信息确定用户设备不再同意数据调用表示所对应的操作，则授权验证网元向服务消费网元发送数据调用通知(Nnwdaf_AnalyticsSubscription_Notify)消息，该数据调用通知消息包括终止指示(Termination Request)，该终止指示用于指示服务消费网元终止对用户数据进行处理，或者说该终止指示用于指示服务消费网元终止调用用户数据。
420，服务消费网元停止处理个人数据。
示例性地，服务消费网元接收来自授权验证网元的数据调用通知消息，根据该数据调用通知消息确定用户不再同意对用户数据执行操作指示所对应的操作，则服务消费网元停止对用户数据进行处理，或者说服务消费网元通知对用户数据执行操作指示所对应的操作。具体例如，服务消费网元撤销对数据调用的订阅，并删除个人数据等。服务消费网元可以向授权验证网元再次发送取消数据调用消息，从而撤销之前对数据调用的订阅。取消数据调用消息可以包含Nnwdaf_AnalyticsSubscription_Unsubscribe等。服务消费网元删除之前获得的用户数据#2。
图5示出了一种数据调用的方法500的示例性流程图。该方法500包括：
501，服务消费网元向授权验证网元发送数据调用请求消息。
502，授权验证网元判断是否需要校验用户意向。
应理解，步骤501与步骤502与方法400中的步骤404和步骤405类似，不在赘述。
如果授权验证网元确定本次数据调用不需要校验用户意向，则授权验证网元跳过步骤503至510。在511，授权验证网元向服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝服务消费网元的数据调用请求。
如果授权验证网元确定本次数据调用需要校验用户意向，则授权验证网元通过存储网元校验用户意向。具体校验方法与方法400中提供的校验方案类似，即步骤503至步骤508与方法400中的步骤407至步骤412类似，这里不再重复说明。
如果用户同意对个人数据执行服务消费网元所请求的操作，则授权验证网元验证服务消费网元是否支持停止数据处理，或者说授权验证网元验证服务消费网元是否具备停止数据处理的能力。示例性地：
509，授权验证网元向服务消费网元发送停止数据处理能力验证请求消息。
示例性地，该停止数据处理能力验证请求消息用于请求获取服务消费网元停止数据处理的能力，或者说，该停止数据处理能力验证请求消息用于查询该服务消费网元是否具备支持停止数据处理。
510，服务消费网元向授权验证网元发送停止数据处理能力验证响应消息。
示例性地，响应于来自授权验证网元的停止数据处理能力验证请求消息，服务消费网元向授权验证网元发送停止数据处理能力验证响应消息，该停止数据处理能力验证响应消息包括能力指示信息，该能力指示信息用于指示该服务消费网元是否支持停止数据处理。
对应的，授权验证网元接收来自服务消费网元的停止数据处理能力验证响应消息，根据该响应消息中携带的能力指示信息确定服务消费网元是否支持停止数据处理。
在另一种可能的实现方式中，如果服务消费网元支持停止数据处理，则服务消费网元在接收到来自授权验证网元的停止数据处理能力校验请求消息之后，通过停止数据处理能力验证响应消息向授权验证网元发送支持停止数据处理能力指示信息，该支持停止数据处理能力指示信息用于指示该服务消费网元支持停止数据处理；如果服务消费网元不支持停止数据处理，则服务消费网元在接收到来自授权验证网元的停止数据处理能力校验请求消息后，可以不回复该停止数据处理能力校验请求消息。授权验证网元在向服务消费网元发送了停止数据处理能力验证请求消息后，可以设置一个定时器，如果定时器计时结束，授权验证网元仍然没有接收到来自服务消费网元发送的停止数据处理能力验证响应消息，则授权验证网元确定服务消费网元不支持停止数据处理。
应理解，授权验证网元可以先确定用户意向，再确定服务消费网元是否具备停止数据处理的能力，也可以先确定服务消费网元是否具备数据处理的能力，再确定用户意向，本申请不做限定。
如果授权验证网元确定服务消费网元不具备支持停止数据处理的能力，则在511，授权验证网元向服务消费网元发送数据调用响应消息，该数据调用响应消息用于拒绝服务消费网元的数据调用请求消息。
如果授权验证网元确定服务消费网元具备支持停止数据处理的能力，且用户同意对用户数据执行数据调用标识对应的操作，则授权验证网元通过服务提供网元获取用户数据#1，并向服务消费网元发送处理之后的用户数据#2，具体过程如步骤512至步骤514所示。应理解，步骤512至步骤514与方法400中的步骤414至步骤416，为了简洁，不再重复说明。
如果用户更改了用户意向，则存储网元需要通知授权验证网元，然后授权验证网元指示服务消费网元停止处理个人数据，具体过程如步骤515至步骤518所示。应理解，步骤515至步骤518与方法400中的步骤417至步骤420类似，为了简洁，不再重复说明。
