在步骤S401中，接收网络设备发送的第二指示信息，其中，第二指示信息用于指示网络设备的用户面定位能力。
需要说明的是，图4所示实施例可以独立实施，也可以与本公开中至少一个其他实施例结合实施，具体可以根据需要选择，本公开并不限制。例如，与图2所示的实施例结合，或者与图3所述的实施例结合，或者与图2和图3所述的实施例结合。
在一些实施例中，网络设备可以向终端发送的第二指示信息，终端根据第二指示信息可以确定网络设备的用户面定位能力。

例如，终端可以在用户策略容器中新增第一指示信息，第一指示信息可以指示终端的用户面定位能力。进而在注册过程中，可以在注册请求中携带该用户策略容器发送至网络设备(例如AMF)。
PCF在AMF接收到用户策略容器时可以得到通知，AMF可以向PCF发送用户策略容器，例如可以基于Namf_Communication_N1N2MessageTransfer服务将用户策略容器发送至PCF，除了发送用户策略容器，AMF还可以向PCF发送SUPI(Subscriber Permanent  Identifier，签约用户永久标识)等信息。
进而PCF可以确定用户面定位关联参数，并再通过用户策略容器发送至AMF，其中，用户面定位关联参数包括以下至少之一：第二指示信息、用户面定位相关策略。据此，用户策略容器包含了第二指示信息，AMF可以将从PCF接收到的用户策略容器透传至终端，例如携带在下行非接入层传输消息中发送至终端，从而终端可以根据用户策略容器中的第二指示信息确定网络设备的用户面定位能力。
在进一步的实施例中，终端还可以根据接收到的用户面定位关联参数对终端中的用户面定位关联参数进行更新，例如更新终端中已有的网络的用户面定位能力，并将更新结果发送至AMF。
在进一步地实施例中，终端可以根据更新后的网络的用户面定位能力、终端的用户面定位能力和配置信息(例如前文的配置信息，此处不再赘述)，确定是否使用用户面定位。
在一些实施例中，网络设备可以在PCF没有接收到终端的请求的情况下，将第二指示信息发送至终端，第二指示信息可以携带在终端策略容器中。终端的请求包括以下至少之一：终端的初始注册请求、重新注册到5G系统的请求。

当PCF确定终端的用户策略信息需要更新，PCT可以将更新后的用户策略信息携带在用户策略容器发送至AMF，其中，更新后的用户策略信息包含第二指示信息。AMF可以将从PCF接收到的用户策略容器透传至终端，例如携带在下行非接入层传输消息中发送至终端，从而终端可以根据用户策略容器中的第二指示信息确定网络设备的用户面定位能力。
在进一步的实施例中，终端还可以根据接收到的用户面定位关联参数对终端中的用户面定位关联参数进行更新，例如更新终端中已有的网络的用户面定位能力，并将更新结果发送至AMF。
在进一步地实施例中，终端可以根据更新后的网络的用户面定位能力、终端的用户面定位能力和配置信息(例如前文的配置信息，此处不再赘述)，确定是否使用用户面定位。
在一些实施例中，终端在根据用户面定位能力确定是否使用用户面定位之后，可以开始用户面连接(User Plane connection)过程。关于用户面连接过程可以参考3GPP TS 23.273等条款，本公开在此不再赘述。

需要说明的是，网络设备向终端发送第二指示信息，可以根据终端的用户面定位能力执行，也可以无需根据终端的用户面定位能力执行。例如网络设备在没有确定终端是否有用户面定位能力的情况下(例如没有接收到第一指示信息)，也可以向终端发送第二指示信息。
在一些实施例中，终端的用户面定位能力包括以下至少之一：对于位置服务消息的支持能力；对于长期演进定位协议消息的支持能力。
在一些实施例中，第一指示信息携带在以下至少之一中：5G移动管理能力；用户策略容器。
在一些实施例中，第一指示信息包括第一字段，第一字段用于指示终端对于位置服务消息的支持能力，以及对于长期演进定位协议消息的支持能力。
第一指示信息可以通过第一字段一起指示终端对于位置服务消息的支持能力，以及对于长期演进定位协议消息的支持能力，例如可以指示两种情况，一种是终端支持位置服务消息，且支持长期演进定位协议消息，另一种是终端不支持位置服务消息，且不支持长期演进定位协议消息。
例如5G管理能力可以包括15个字节(octet)，每个字节占8个比特(bit)。例如第9个字节中后6个比特以及第9至第15个字节中的比特是空闲的，第一指示信息中的第一字段可以在空闲的比特中占1比特，例如第一字段可以位于第9个字节中的第3个比特。
例如，第一字段的值为1，可以指示终端支持位置服务消息，且支持长期演进定位协议消息，第一字段的值为0，可以指示终端支持位置服务消息，且不支持长期演进定位协议消息。
需要说明的是，上述实施例所述的第一指示信息的位置仅为示例，并不构成对第一指示信息的位置的限定。
在一些实施例中，第一指示信息包括第一字段和第二字段，其中，第一字段用于指示终端对于位置服务消息的支持能力，第二字段用于指示终端对于长期演进定位协议消息的支持能力。
第一指示信息可以分别指示终端对于位置服务消息的支持能力，以及对于长期演进定位协议消息的支持能力。例如第一指示信息包括第一字段和第二字段，第一字段可以指示终端支持位置服务消息或不支持位置服务消息，第二字段可以指示终端支持长期演进定位协议消息或不支持长期演进定位协议消息。
例如5G管理能力可以包括15个字节(octet)，每个字节占8个比特(bit)。例如第9个字节中后6个比特以及第9至第15个字节中的比特是空闲的，第一指示信息可以在空闲的比特中占2比特，例如第一指示信息可以位于第9个字节中的第3和第4个比特，其中，第一字段可以位于第9个字节中的第3个比特，第二字段可以位于第9个字节中的第4个比特。
例如，第一字段的值为1，可以指示终端支持长期演进定位协议消息，第一字段的值为0，可以指示终端不支持长期演进定位协议消息。
例如，第二字段的值为1，可以指示终端支持位置服务消息，第二字段的值为0，可以指示终端不支持位置服务消息。
需要说明的是，上述实施例所述的第一指示信息的位置仅为示例，并不构成对第一指示信息(包括第二字段或第三字段的位置)的位置的限定。
在一些实施例中，第二指示信息携带在以下至少之一中：注册接受消息；终端策略容器。
在一些实施例中，终端策略容器可以携带在下行非接入层传输消息中，策略控制功能可以将下行非接入层传输消息携带在Namf_Communication_N1N2MessageTransfer发送至AMF，AMF将其中的用户策略容器透传到终端。
在一些实施例中，第二指示信息携带在终端策略容器中，网络设备的用户面定位能力属于用户面定位关联参数，终端可以基于用户面定位关联参数进行用户面定位。其中，用户面定位关联参数除了包括网络设备的用户面定位能力，还可以包括用户面定位相关策略等信息。
在一些实施例中，网络设备可以在注册过程中将第二指示信息发送至终端，第二指示信息可以携带在注册接受消息中。
例如，终端可以在注册过程中，可以向网络设备发送注册请求消息。
其中，注册请求消息可以包含5G移动管理能力的信息元。在一些实施例中，5G移动管理能力则可以进一步包含终端向网络设备发送的第一指示信息，第一指示信息可以指示终端的用户面定位能力。
网络设备接收到注册请求消息后，可以基于注册请求消息中的信息启动5G移动管理的通用程序，例如注册过程中的识别、认证和安全程序。
当网络设备接受终端的注册请求，网络设备(例如AMF)可以向终端发送注册接受消息，在注册接受消息中，可以携带上述第二指示信息，用于指示网络设备的用户面定位能力。
在一些实施例中，网络设备可以在PCF接收到终端的请求的情况下，将第二指示信息发送至终端，第二指示信息可以携带在终端策略容器中。终端的请求包括以下至少之一：终端的初始注册请求、重新注册到5G系统的请求。
例如，终端可以在用户策略容器中新增第一指示信息，第一指示信息可以指示终端的用户面定位能力。进而在注册过程中，可以在注册请求中携带该用户策略容器发送至网络设备(例如AMF)。
PCF在AMF接收到用户策略容器时可以得到通知，AMF可以向PCF发送用户策略容器，例如可以基于Namf_Communication_N1N2MessageTransfer服务将用户策略容器发送至PCF，除了发送用户策略容器，AMF还可以向PCF发送SUPI等信息。
进而PCF可以确定用户面定位关联参数，并再通过用户策略容器发送至AMF，其中，用户面定位关联参数包括以下至少之一：第二指示信息、用户面定位相关策略。据此，用户策略容器包含了第二指示信息，AMF可以将从PCF接收到的用户策略容器透传至终端，例如携带在下行非接入层传输消息中发送至终端，从而终端可以根据用户策略容器中的第二指示信息确定网络设备的用户面定位能力。
在进一步的实施例中，终端还可以根据接收到的用户面定位关联参数对终端中的用户面定位关联参数进行更新，例如更新终端中已有的网络的用户面定位能力，并将更新结果发送至AMF。
在进一步的实施例中，终端可以根据更新后的网络的用户面定位能力、终端的用户面定位能力和配置信息(例如前文的配置信息，此处不再赘述)，确定是否使用用户面定位。
在一些实施例中，网络设备可以在PCF没有接收到终端的请求的情况下，将第二指示信息发送至终端，第二指示信息可以携带在终端策略容器中。终端的请求包括以下至少之一：终端的初始注册请求、重新注册到5G系统的请求。
例如，当满足第一条件时，PCF可以主动确定终端的用户策略信息是否需要更新，其中，第一条件包括以下至少之一：终端的位置改变、PCF订阅的S-NSSAI改变。
当PCF确定终端的用户策略信息需要更新，PCT可以将更新后的用户策略信息携带在用户策略容器发送至AMF，其中，更新后的用户策略信息包含第二指示信息。AMF可以将从PCF接收到的用户策略容器透传至终端，例如携带在下行非接入层传输消息中发送至终端，从而终端可以根据用户策略容器中的第二指示信息确定网络设备的用户面定位能力。
在进一步的实施例中，终端还可以根据接收到的用户面定位关联参数对终端中的用户面定位关联参数进行更新，例如更新终端中已有的网络的用户面定位能力，并将更新结果发送至AMF。
在进一步地实施例中，终端可以根据更新后的网络的用户面定位能力、终端的用户面定位能力和配置信息(例如前文的配置信息，此处不再赘述)，确定是否使用用户面定位。
在一些实施例中，终端在根据用户面定位能力确定是否使用用户面定位之后，可以开始用户面连接过程。关于用户面连接过程可以参考3GPP TS 23.273等条款，本公开在此不再赘述。
