在一个示例中，结合图4、5，对本申请实施例提供的地址获取方法进行举例说明。在该示例中，移动边缘计算网元可以为MEC实体，业务能力开放网元可以为SCEF实体，内容服务器可以为SCS/AS，终端可以为UE。MEC实体可以部署有APP，使得UE可以通过应用层向MEC实体传送消息。在该示例的一个例子中，MEC实体可以本地部署服务器，该服务器可以对UE的地址信息进行相关处理。
MEC实体获取UE网络地址信息以及向SCEF实体发送报告信息的过程可如图4所示。
步骤401、UE附着到网络。
步骤402、UE通过应用层向部署在MEC实体上的APP发送UE信息。其中，UE信息包括UE的地理位置信息和UE标识信息等。
MEC实体可以将UE的地理位置信息转换为网络地址信息。在一个例子中，可以通过步骤403和步骤404将地理位置信息转换为网络地址信息。
步骤403、APP向MEC实体本地部署的服务器送该地理位置信息。
步骤404、MEC实体本地部署的服务器处理地理位置信息，将UE的地理位置转换为网络地址信息(例如UE所属的基站标识、小区标识等)并保存网络地址信息。服务器如何将地理位置转换为网络地址信息可以参见现有标准中的技术，在此不再赘述。
步骤405、MEC实体向SCEF实体发送报告信息，该报告信息包括该MEC实体的标识信息和UE标识信息等。
经过上述流程，SCEF实体获取了UE标识和保存有该UE标识对应UE的网络地址信息的MEC实体标识，在SCEF实体需要获取UE的地址信息时可以到保存UE地址信息的MEC实体去请求UE的地址信息。具体过程可以如图5所示。
步骤501、SCS/AS向SCEF实体发送监控请求，以订阅UE的地址信息。监控请求包括UE标识信息、SCS/AS标识等。
步骤502、SCEF实体可以根据UE标识信息确定MEC实体。在步骤405的报告信息中，含有MEC实体的标识信息、UE标识信息等。SCEF实体可以根据UE标识信息和报告信息确定保存该UE地址信息的MEC实体。在一个例子中，SCEF实体接收到监控请求后，还可以对SCS/AS进行鉴权，以确定是否允许SCS/AS使用SCEF实体提供的服务。
步骤503、SCEF实体向MEC实体发送地址请求，地址请求可以包括UE标识信息、SCEF实体标识信息。
步骤504、MEC实体向SCEF实体发送UE的网络地址信息，网络地址信息可以包括UE所属的基站标识、小区标识等。
需要说明的是，当UE处于连接态时，SCEF实体可以获取该UE当前的小区粒度的网络地址信息；当UE处于空闲态时，SCEF实体获取的是UE最后被知道的网络地址信息。
MEC实体通过应用层获取终端的地址，从而减少了基站、MEC实体之间的信令交互；SCEF实体可以从MEC实体获取终端的地址，从而无须MME开启地址上报过程，就能使得SCEF实体获取UE的地址信息，节省了S1-MME接口的信令，减少了MME的压力。
在一个示例中，结合图6，对本申请实施例提供的地址获取方法进行举例说明。在该示例中，移动边缘计算网元可以为MEC实体，业务能力开放网元可以为SCEF实体，内容服务器可以为SCS/AS，终端可以为UE。MEC实体获取UE网络地址信息的过程可如图6所示。

步骤603、基站向MEC实体发送UE信息，具体地，UE信息包括UE标识信息、网络地址信息，可选的，网络地址信息可以包括UE所属小区标识和/或UE所属基站标识。在一个例子中，网络地址信息还可以包括TAI和/或RAI。
步骤604、MEC实体保存网络地址信息。
步骤605、MEC实体向SCEF实体发送报告信息，该信息包括UE标识信息、MEC实体的标识信息等。
步骤606、UE向基站发送UE信息，该UE信息包括新的网络地址信息。当UE所处位置发生了变化，UE向基站发送位置变化了之后的网络地址信息，即新的网络地址信息，新的网络地址信息包括UE位置变化了之后的所属小区标识，在一个例子中，还可以包括TAI和/或RAI。
步骤607、基站将步骤606中的UE信息发送给MEC实体。
步骤609、MEC实体根据步骤606中的UE信息对其保存的网络地址信息进行更新，并保存更新后的网络地址信息。
经过上述流程，SCEF实体获取了UE标识信息和保存UE网络地址信息的MEC实体标识信息，在SCEF实体需要获取UE的网络地址信息时可以到保存UE网络地址信息的MEC实体去请求UE的网络地址信息。具体过程可以参见图5所示内容和上文中对图5的说明。
在该示例中，终端附着到网络后通过基站主动向MEC实体上报网络地址信息，无须MEC实体进行地理位置信息和网络地址信息的转换；SCEF实体需要终端地址时，可以直接从MEC实体获取，并且无须MME开启地址上报过程，就能使得SCEF实体获取UE的地址信息，节省了S1-MME接口的信令，减少了MME的压力。
在一个示例中，结合图7，对本申请实施例提供的地址获取方法进行举例说明。在该示例中，移动边缘计算网元可以为MEC实体，业务能力开放网元可以为SCEF实体，第三方服务器可以为SCS/AS，终端可以为UE。MEC实体获取UE地址信息过程可以参见图4或图6所示的内容，以及上文中对图4或图6的说明。需要说明的是，与图4或图6所示内容不同的是，在该示例中，MEC实体并不主动向SCEF实体发送报告信息。SCEF实体可以根据UE的地理位置信息确定MEC实体，进而向MEC实体发送地址请求，具体过程如图7所示。
步骤701、UE通过应用层向SCS/AS上报地理位置信息。
步骤702、SCS/AS向SCEF实体发送监控请求，该监控请求包括UE标识信息、UE的地理位置信息、SCS/AS标识等。
步骤703、SCEF实体确定MEC实体。具体地，SCEF实体可以根据UE的地理位置信息大致确定UE所处的位置，然后根据UE所处的位置转换为MEC实体地址，有可能无法精确到具体一个MEC实体，有可能确定多个MEC实体，因此，后续步骤中的，地址请求可能发送到多个MEC实体。在一个例子中，SCEF实体还可以根据SCS/AS标识对SCS/AS进行鉴权，以决定是否允许SCS/AS使用SCEF实体提供的服务。
步骤704、SCEF实体向MEC实体发送地址请求，地址请求包括所述UE标识信息。
步骤705、SCEF实体从MEC实体接收UE网络地址信息。其中，网络地址信息中可以包括小区标识、基站标识等。当UE所处的位置发生了变化，从MEC实体接收UE地址信息可以为UE位置变化了之后的网络地址信息，UE位置变化了之后的网络地址信息包括UE标识、UE在位置变化了之后所属小区标识，还包括TAI和/或RAI。并且SCEF实体可以根据接收的UE位置变化了之后的网络地址信息对SCEF实体之前接收的网络地址信息进行更新。
在该示例中，无须MEC实体向SCEF实体上报信息，SCEF实体通过应用层消息确定MEC实体，从而节省MEC实体与SCEF实体之间信令，并且无须MME开启地址上报过程，就能使得SCEF实体获取UE的地址信息，节省了S1-MME接口的信令，减少了MME的压力。
在一个示例中，结合图8，对本申请实施例提供的地址获取方法进行举例说明。在该示例中，移动边缘计算网元可以为MEC实体，业务能力开放网元可以为SCEF实体，内容服务器可以为SCS/AS，终端可以为UE。
MEC实体获取UE地址信息过程可以参见图4或图6所示的内容，以及上文中对图4或图6的说明。需要说明的是，与图4或图6所示内容不同的是，在该示例中，MEC实体并不主动向SCEF实体发送报告信息。SCEF实体可以利用HSS、MME确定UE所属基站，然后根据基站确定MEC实体，具体过程如图8所示。
步骤801、SCS/AS向SCEF实体发送监控请求，该监控请求包括UE标识信息、SCS/AS标识等。
步骤802、确定HSS。具体的，SCEF实体根据UE标识信息确定HSS。在一个例子中，SCEF实体还可以根据SCS/AS标识信息对SCS/AS进行鉴权，以决定是否允许SCS/AS使用SCEF实体的提供服务。
步骤803、SCEF实体向HSS发送监控请求消息，其中包括UE标识信息，该监控请求用于请求UE所属基站的标识。
步骤804、确定MME。具体的，HSS根据监控请求消息确定相关的MME是否支持该监控请求消息。更具体的，SCEF实体可以对应一个或多个MME，一个或多个MME可以支持多种业务，其中不同的MME可以支持不同的业务，也可以支持相同的业务，例如，在本示例中，对于根据UE标识信息确定UE所述的基站，并上报基站标识，这一业务，有的MME可以支持，有的MME可以不支持。HSS可以存储MME支持业务的相关信息以及UE标识信息与MME的对应关系，因此，HSS可以根据监控请求消息中的UE标识信息确定MME，进而确定该MME是否支持该监控请求消息。
步骤805、如果UE标识信息对应的MME支持该监控请求消息，HSS向该MME发送位置请求消息，其中包括UE标识信息，位置请求信息用于请求UE所述基站的标识，UE标识信息可以为IMSI和/MSISDN。
另外，如果UE标识信息对应的MME不支持该监控请求，HSS可以向SCEF实体反馈相应的信息，以通知SCEF实体监控请求被拒绝；可选的，SCEF实体可以向SCS/AS反馈相应的信息，SCEF实体可以向SCS/AS反馈相应的信息，以通知SCS/AS监控请求被拒绝。可选的，HSS向SCEF实体反馈的信息中以及SCEF实体向SCS/AS反馈的实体中可以包括监控请求被拒绝的原因，例如，相关MME不支持基站信息上报等。
步骤806、MME向HSS发送监控请求响应，其中包括UE所属的基站标识。具体地，MME可以根据UE标识确定UE，然后向HSS发送该UE所属的基站标识。
步骤807、HSS向SCEF实体发送监控请求响应，其中包括UE标识信息、基站标识信息，UE标识信息可以是IMSI、MSISDN、外部标识中的至少一种。
步骤808、确定MEC实体。SCEF实体可以根据基站标识确定UE所属的MEC实体。具体的，SCEF实体中存储有一个或多个基站的覆盖区域和基站覆盖区域内的MEC实体，因此，SCEF实体获取了基站标识后，可以确定基站，进而确定该基站覆盖区域内的MEC实体。
步骤809、向MEC实体发送地址请求，地址请求可以包括UE标识信息，UE标识信息可以是IMSI、MSISDN、外部标识中的至少一种。
步骤810、MEC实体向SCEF实体发送UE的网络地址信息，地址信息可以包括UE所属小区标识等。
在该示例中，SCEF实体通过核心网获取终端所述基站，然后根据基站确定MEC实 体，进而可以从MEC实体获取终端的地址信息，从而无须MME开启地址上报过程，就能使得SCEF实体获取UE的地址信息，节省了S1-MME接口的信令，减少了MME的压力。
