通知对象地址(Notification target address)，用于指示数据上报的目的地址，如这里可以将其设为数据消息网元自身的地址(如SMF地址)，或其他目的网元地址(如数据消费网元的地址)等。
UPF网元按需采集数据后，将数据反馈给数据消费网元指定的目的地址。
具体地，一种实现中，该目的地址为SMF网元的地址，也即需要经过SMF网元向数据消费网元中转数据；另一种实现中，目的地址为数据消费网元的地址，也即直接将数据发往数据消费网元。
一种实施例中，所述数据消费网元包括网络数据分析功能网元或应用功能网元，所述第一网元包括会话管理功能网元；或，
所述数据消费网元包括网络数据分析功能网元或应用功能网元，所述第一网元包括网络存储功能网元；或，
所述数据消费网元包括会话管理功能网元，所述第一网元包括网络存储功能网元。
需要说明的是，会话管理功能网元为具有会话管理功能的网元，例如，会话管理功能网元为SMF。网络存储功能网元为具有网络存储功能的网元，例如，网络存储功能网元为NRF。网络数据分析功能网元为具有网络数据分析功能的网元，例如，网络数据分析功能网元为NWDAF。应用功能网元可以为AF。
一种可选的实施方式，当所述数据消费网元包括会话管理功能网元，所述第一网元包括网络存储功能网元时，所述方法还包括：
所述数据消费网元接收第二网元发送的网元信息获取请求，所述网元信息获取请求包含第三信息；所述第三信息用于确定与所述第三信息匹配的用户面功能网元；所述数据消费网元向所述第二网元发送网元信息获取响应，所述网元信息获取响应包括所述目标用户面功能网元的信息；

一种实施方式中，第二网元可以是网络数据分析功能网元(NWDAF网元)或应用功能网元(AF网元)。
一种实施方式中，所述数据消费网元根据第三信息确定第一信息。第一信息中的每一项可以与第三信息对应的信息相同，也可以不同，本实施例不做限定。例如，第二网元向数据消费网元(SMF网元)发送的第一信息中包括的是第二网元的感兴趣的区域，例如TA1、TA2和TA3，数据消费网元根据第一信息确定对TA1和TA2感兴趣，则第一信息中的目标区域的信息可以为TA1和TA2，数据消费网元根据第一信息确定对TA1、TA2和TA3都感兴趣，则第一信息中的目标区域的信息可以为TA1、TA2和TA3。
在本申请实施例中，通过网元发现响应消息中的间接获取能力指示信息指示数据消费网元间接从UPF网元获取数据，提高了数据获取被SMF网元管控的可能性。

1、UPF网元向NRF网元发起网元注册请求(UPF type，Supported service name，UPF service area，(indirect exposure，event IDs，SMF ID/service area)，(direct exposure，event IDs))，所述网元注册请求用于将UPF网元自身的网元信息注册到NRF网元中。
2、NWDAF/AF网元向NRF网元发起网元发现请求(UPF type，AOI，event ID)。
3、NRF网元若确定UPF网元支持event ID的直接订阅，则根据AOI确定UPF网元instance(s)。
4、NRF网元反馈网元发现响应(UPF网元instance(s)，direct event exposure indication)。
NWDAF/AF网元根据direct event exposure indication，确定执行直接订阅。
5、NWDAF/AF网元向UPF网元发起数据获取请求(event ID，event filter，target of event等)。

2、NWDAF/AF网元向NRF网元发起网元发现请求(UPF type，AOI，event ID)。
3、NRF网元若确定UPF网元支持event ID的间接订阅，则根据AOI确定SMF网元ID，可选地，确定UPF网元instance(s)。
4、NRF网元反馈网元发现响应(SMF网元ID，UPF网元instance(s)，indirect event exposure indication)。
NWDAF/AF网元根据indirect event exposure indication，确定执行间接订阅。
5、NWDAF/AF网元向SMF网元发起数据获取请求(UPF网元instance(s)，UPF data collection indication，event ID，event filter，target of event等)。

7a、UPF网元向SMF网元反馈数据获取响应(event ID，data)。
7b、UPF网元向NWDAF/AF网元反馈数据获取响应(event ID，data)。
