The SMF shall select the PSA-UPF (located at the central site or local site) connected to the first network element for the PDU session based on the S-NSSAI, DNN and terminal location information.

经由用户面的定位信令具有若干优点，例如：Positioning signaling via the user plane has several advantages, such as:

通过从LCS服务器到终端的直接连接，它具有更有效的通信过载；It has more efficient communication overload through direct connection from LCS server to terminal;

它可能不需要RRC、NG-AP和HTTP/2协议栈的gNodeB、AMF、LMF信令处理。单个会话可以处理所有事务；It may not require the gNodeB, AMF, LMF signaling processing of RRC, NG-AP and HTTP/2 protocol stack. A single session can handle all transactions;

根据终端的支持，它可以有多种选择。例如，在定位方法的选择中，3GPP LPP和OMA LPPe都是可能的。It can have multiple options depending on the support of the terminal. For example, in the selection of positioning method, both 3GPP LPP and OMA LPPe are possible.

在一些实施例中，关联标识(Correlation ID)是核心网内部的标识，只能在核心网使用，路由标识(Routing ID)可以在终端使用。In some embodiments, the correlation ID is an identifier within the core network and can only be used in the core network, while the routing ID can be used in the terminal.

在一些实施例中，路由标识和关联标识可以是同一标识符的不同术语。在一些实施例中，术语“关联标识”用于第一网元和第二网元之间的服务操作中的标识符，而术语“路由标识”用于通过终端和第二网元之间的N1参考点发送的NAS消息中的标识符。In some embodiments, the routing identifier and the association identifier may be different terms for the same identifier. In some embodiments, the term "association identifier" is used for an identifier in a service operation between a first network element and a second network element, and the term "routing identifier" is used for an identifier in a NAS message sent over an N1 reference point between a terminal and a second network element.

在一些实施例中，在与LCS相关的过程中，在第一网元、第二网元和终端之间使用关联标识(或路由标识)来识别第一网元以及第一网元与终端之间的LCS会话，例如，当第二网元从终端接收到消息和路由标识时，第二网元可以将路由标识映射到关联标识，并将消息发送到由关联标识识别的第一网元。In some embodiments, in a process related to LCS, an association identifier (or routing identifier) is used between a first network element, a second network element, and a terminal to identify the first network element and the LCS session between the first network element and the terminal. For example, when the second network element receives a message and a routing identifier from the terminal, the second network element can map the routing identifier to the association identifier and send the message to the first network element identified by the association identifier.

在一些实施例中，网络发起的UPP-CM过程包括：In some embodiments, the network-initiated UPP-CM process includes:

网络发起用户面连接建立：The network initiates the establishment of a user plane connection:

网络向终端发送用户面连接建立命令消息；The network sends a user plane connection establishment command message to the terminal;

上述UPP-CM消息包含在UL/DL NAS TRANSPORT消息的UPP-CMI容器中，并通过AMF在UE和LMF之间传输。The above UPP-CM message is contained in the UPP-CMI container of the UL/DL NAS TRANSPORT message and transmitted between the UE and LMF through the AMF.

图2是根据本公开实施例示出的用户面定位连接的处理方法的交互示意图。如图2所示，本公开实施例涉及用户面定位连接的处理方法，用于通信系统100，上述方法包括：FIG2 is an interactive schematic diagram of a method for processing a user plane positioning connection according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for processing a user plane positioning connection, which is used in a communication system 100, and the method includes:

步骤S2101、第一网元1021向第二网元1022发送第一标识以及第一消息。Step S2101: The first network element 1021 sends a first identifier and a first message to the second network element 1022.

在一些实施例中，第二网元1022接收第一标识以及第一消息。In some embodiments, the second network element 1022 receives the first identifier and the first message.

在一些实施例中，第一消息为与建立用户面连接相关的消息或者释放用户面连接相关的消息。In some embodiments, the first message is a message related to establishing a user plane connection or a message related to releasing a user plane connection.

在一些实施例中，第一消息为用户面连接建立命令消息、用户面连接建立响应消息、用户面连接释放命令消息或用户面连接释放响应消息。In some embodiments, the first message is a user plane connection establishment command message, a user plane connection establishment response message, a user plane connection release command message, or a user plane connection release response message.

在一些实施例中，第一标识用于标识第一信息，第一信息为第一网元、用户面连接或者第一网元与终端的定位服务会话中的至少一者。In some embodiments, the first identifier is used to identify the first information, and the first information is at least one of the first network element, the user plane connection, or the positioning service session between the first network element and the terminal.

在一些实施例中，第一标识可以仅用于在核心网中标识第一信息，还可以用于在核心网以及终端中标识第一信息。应当理解的是，若第一标识仅用于在核心网中标识第一信息，那么如果第二网元将第一标识发给终端，终端并不能根据第一标识确定该第一标识所标识的第一信息，同理，若第一标识可用于在核心网以及终端中标识第一信息，那么如果第二网元将第一标识发给终端，终端可以根据第一标识确定该第一标识所标识的第一信息。In some embodiments, the first identifier can be used only to identify the first information in the core network, and can also be used to identify the first information in the core network and the terminal. It should be understood that if the first identifier is used only to identify the first information in the core network, then if the second network element sends the first identifier to the terminal, the terminal cannot determine the first information identified by the first identifier based on the first identifier. Similarly, if the first identifier can be used to identify the first information in the core network and the terminal, then if the second network element sends the first identifier to the terminal, the terminal can determine the first information identified by the first identifier based on the first identifier.

在一些实施例中，第一标识用于标识第一网元时，第一标识可以是第一网元的IP地址，关联标识等等。由于核心网设备以及终端都能够根据第一网元的IP地址确定第一网元，因此，如果第一标识为第一网元的IP地址，则说明该第一标识是用于在核心网以及终端中标识第一网元。而关联标识仅用于在核心网中标识第一网元，所以如果第一标识为关联标识，说明该第一表示用于在核心网中标识第一网元。In some embodiments, when the first identifier is used to identify the first network element, the first identifier may be an IP address of the first network element, an associated identifier, etc. Since both the core network device and the terminal can determine the first network element according to the IP address of the first network element, if the first identifier is the IP address of the first network element, it means that the first identifier is used to identify the first network element in the core network and the terminal. The associated identifier is only used to identify the first network element in the core network, so if the first identifier is an associated identifier, it means that the first identifier is used to identify the first network element in the core network.

本公开实施例的第一网元通过向第二网元发送第一消息时还进一步发送了用于标识第一信息的第一标识，使得第二网元可以将第一消息转发到与终端相关的第一网元，并且可以帮助终端识别第一网元。The first network element of the embodiment of the present disclosure further sends a first identifier for identifying the first information when sending the first message to the second network element, so that the second network element can forward the first message to the first network element related to the terminal and can help the terminal identify the first network element.

本公开实施例的UPP-CM过程包括建立用户面连接和释放用户面连接，并且由于UPP-CM过程的发起方可以是网络也可以是终端，因此，本申请实施例的UPP-CM过程可以包括4种方案，下面分别针对不同的方案具体说明步骤S2101。The UPP-CM process of the embodiment of the present disclosure includes establishing a user plane connection and releasing the user plane connection. Since the initiator of the UPP-CM process can be a network or a terminal, the UPP-CM process of the embodiment of the present application can include 4 schemes. Step S2101 is specifically described below for different schemes.

方案一网络发起用户面连接Solution 1: The network initiates the user plane connection

步骤S2101可以包括：第一网元确定为用户面定位建立用户面连接，分配第一标识，向第二网元发送第一标识以及第一消息，第一消息为用户面连接建立命令消息。Step S2101 may include: the first network element determines to establish a user plane connection for user plane positioning, allocates a first identifier, and sends the first identifier and a first message to the second network element, where the first message is a user plane connection establishment command message.

也就是说，当由网络发起用户面连接时，步骤S2101中的第一标识是由第一网元分配的。That is, when the user plane connection is initiated by the network, the first identifier in step S2101 is allocated by the first network element.

在一些实施例中，第一网元可以向第二网元调用Namf_Communication_N1N2MessageTransfer，以传输用户面连接建立命令消息以及第一标识。In some embodiments, the first network element may call Namf_Communication_N1N2MessageTransfer to the second network element to transmit the user plane connection establishment command message and the first identifier.

方案二终端发起用户面连接Solution 2: The terminal initiates a user plane connection

步骤S2101可以包括：Step S2101 may include:

方式1)终端向第二网元发送用户面连接建立请求，第二网元向第一网元发送用户面连接建立请求，第一网元接受用户面连接建立请求，确定为用户面定位建立用户面连接，第一网元分配第一标识，向第二网元发送第一标识以及第一消息，第一消息为用户面连接建立命令消息或者用户面连接建立相应消息。Method 1) The terminal sends a user plane connection establishment request to the second network element, the second network element sends a user plane connection establishment request to the first network element, the first network element accepts the user plane connection establishment request, determines to establish a user plane connection for user plane positioning, the first network element allocates a first identifier, and sends the first identifier and a first message to the second network element, where the first message is a user plane connection establishment command message or a user plane connection establishment corresponding message.

方式2)终端向第二网元发送用户面连接建立请求，第二网元分配第一标识，并向第一网元发送用户面连接建立请求和第一标识，第一网元接受用户面连接建立请求，确定为用户面定位建立用户面连接，向第二网元发送第一标识以及第一消息，第一消息为用户面连接建立命令消息或者用户面连接建立相应消息。Mode 2) The terminal sends a user plane connection establishment request to the second network element, the second network element allocates a first identifier, and sends a The first network element accepts the user plane connection establishment request and the first identifier, determines to establish a user plane connection for user plane positioning, and sends the first identifier and the first message to the second network element, where the first message is a user plane connection establishment command message or a user plane connection establishment corresponding message.

也就是说，当由终端发起用户面连接时，第一标识可以由第一网元分配，也可以由第二网元分配，也即第一标识可以是第一网元确定为用户面定位建立用户面连接而分配的，或者，第一标识是第二网元根据接收到终端发送的用户面连接建立请求而分配的。That is to say, when the terminal initiates a user plane connection, the first identifier can be allocated by the first network element or by the second network element, that is, the first identifier can be allocated by the first network element to establish a user plane connection for user plane positioning, or the first identifier is allocated by the second network element based on a user plane connection establishment request sent by the terminal.

在一些实施例中，终端向第二网元发送用户面连接建立请求具体为：In some embodiments, the terminal sends a user plane connection establishment request to the second network element specifically:

终端将UL NAS TRASPORT消息的有效载荷容器类型设置为“UPP-CMI容器”，并将用户面连接建立请求包括在UL NAS TRASPORT消息中的有效载荷容器中。The terminal sets the payload container type of the UL NAS TRASPORT message to "UPP-CMI container" and includes the user plane connection establishment request in the payload container in the UL NAS TRASPORT message.

方案三网络发起用户面连接释放Solution 3: Network initiates user plane connection release

步骤S2101可以包括：第一网元确定释放用户面连接，向第二网元发送第一标识以及第一消息，第一消息为用户面连接释放命令。Step S2101 may include: the first network element determines to release the user plane connection, and sends a first identifier and a first message to the second network element, where the first message is a user plane connection release command.

需要注意的是，用户面连接释放和用户面连接建立是两个相对独立的方案，也即无论是网络还是终端发起用户面连接，都可以由网络发起用户面连接释放，进一步地，在用户面连接释放的方案中，第一网元向第二网元发送的第一标识，可以是在用户面连接建立过程中由第一网元分配的，也可以是在用户面连接建立过程中由第二网元分配的。It should be noted that user plane connection release and user plane connection establishment are two relatively independent schemes, that is, whether the network or the terminal initiates the user plane connection, the user plane connection release can be initiated by the network. Furthermore, in the user plane connection release scheme, the first identifier sent by the first network element to the second network element can be allocated by the first network element during the user plane connection establishment process, or can be allocated by the second network element during the user plane connection establishment process.

在一些实施例中，第一网元可以向第二网元调用Namf_Communication_N1N2MessageTransfer，以传输用户面连接释放命令消息以及第一标识。In some embodiments, the first network element may call Namf_Communication_N1N2MessageTransfer to the second network element to transmit the user plane connection release command message and the first identifier.

方案四终端发起用户面连接释放Solution 4: The terminal initiates the user plane connection release

步骤S2101可以包括：终端向第二网元发送用户面连接释放请求和第二标识；第二网元向第一网元发送用户面连接释放请求和第一标识；第一网元接受用户面连接释放请求，确定释放用户面连接，向第二网元发送第一标识以及第一消息，第一消息为用户面连接释放响应消息或者用户面连接释放命令消息。Step S2101 may include: the terminal sends a user plane connection release request and a second identifier to the second network element; the second network element sends a user plane connection release request and a first identifier to the first network element; the first network element accepts the user plane connection release request, determines to release the user plane connection, and sends a first identifier and a first message to the second network element, where the first message is a user plane connection release response message or a user plane connection release command message.

在一些实施例中，第二标识用于在终端中标识第一信息。In some embodiments, the second identifier is used to identify the first information in the terminal.

本方案中第二网元向第一网元发送的第一标识，可以是在用户面连接建立过程中由第一网元分配的，也可以是在用户面连接建立过程中由第二网元分配的。In this solution, the first identifier sent by the second network element to the first network element may be allocated by the first network element during the process of establishing the user plane connection, or may be allocated by the second network element during the process of establishing the user plane connection.

在一些实施例中，终端向第二网元发送用户面连接释放请求和第二标识具体为：In some embodiments, the terminal sends the user plane connection release request and the second identifier to the second network element specifically:

终端将UL NAS TRASPORT消息的有效载荷容器类型设置为“UPP-CMI容器”，并将用户面连接释放请求包括在有效载荷容器中，将第二标识包括在UL NAS TRASPORT消息中的附加信息中，终端向第二网元发送DL NAS TRASPORT消息。The terminal sets the payload container type of the UL NAS TRASPORT message to "UPP-CMI container", includes the user plane connection release request in the payload container, includes the second identifier in the additional information in the UL NAS TRASPORT message, and sends a DL NAS TRASPORT message to the second network element.

步骤S2102、第二网元1022向终端101发送第二标识以及第一消息。Step S2102: The second network element 1022 sends a second identifier and a first message to the terminal 101.

在一些实施例中，终端101接收第二标识以及第一消息。In some embodiments, terminal 101 receives the second identifier and the first message.

在一些实施例中，第二标识用于在终端中标识第一信息。根据上述实施例可知，本公开实施例的第一标识可以是用于在核心网中标识第一信息，也可以是在核心网以及终端中标识第一信息，因此，根据第一标识的不同，第二网元向终端发送第二标识以及第一消息包括两种情况：In some embodiments, the second identifier is used to identify the first information in the terminal. According to the above embodiments, the first identifier of the embodiment of the present disclosure can be used to identify the first information in the core network, or can be used to identify the first information in the core network and the terminal. Therefore, according to the difference of the first identifier, the second network element sends the second identifier and the first message to the terminal in two cases:

情况一、第一标识用于在核心网中标识第一信息，第二网元将第一标识映射为第二标识，第二标识用于在终端中标识第一信息，向终端发送第二标识以及第一消息；Case 1: the first identifier is used to identify the first information in the core network, the second network element maps the first identifier to the second identifier, the second identifier is used to identify the first information in the terminal, and the second identifier and the first message are sent to the terminal;

情况二、第一标识用于在核心网和终端中标识第一信息，第二网元将第一标识作为第二标识，向终端发送第二标识和第一消息。Case 2: The first identifier is used to identify the first information in the core network and the terminal. The second network element uses the first identifier as the second identifier and sends the second identifier and the first message to the terminal.
