Among them, the first network element and the target second network element are both core network elements. It can be seen that the present disclosure provides a method for realizing the first service through a user plane connection between a 5GCN and a terminal, which improves service efficiency. The first service can be, for example, a perception service. In addition, in the above embodiment, after the first network element selects the target second network element, it indicates the target second network element to the terminal, so that the terminal can clearly know which network element it wants to establish a user plane connection with, thereby ensuring that the target second network element selected by the first network element for providing the first service to the terminal and the target second network element to establish a user plane connection known to the terminal are the same network element, avoiding the situation that "the target second network element selected by the first network element for providing the first service to the terminal is inconsistent with the target second network element to establish a user plane connection known to the terminal", thereby ensuring the accurate execution of the first service.

在一些技术方案中，如图1B所示，图1B为本公开一个实施例所提供的一种“5GCN与终端之间通过用户面连接实现定位”方法的流程图，如图1B所示，该方法可以包括以下步骤：In some technical solutions, as shown in FIG. 1B , FIG. 1B is a flow chart of a method for “realizing positioning through user plane connection between 5GCN and terminal” provided by an embodiment of the present disclosure. As shown in FIG. 1B , the method may include the following steps:

1.终端向接入与移动性管理功能(Access and Mobility Management Function，AMF)发送上行链路非接入层传输(uplink non-access stratum，UL NAS TRANSPORT)消息，该UL NAS TRANSPORT消息用于请求启动用户面(User Plane，UP)定位(Positioning)。上述的终端还可以称为用户设备(User Equipment，UE)。1. The terminal sends an uplink non-access stratum (UL NAS TRANSPORT) message to the Access and Mobility Management Function (AMF), which is used to request the start of user plane (UP) positioning. The above terminal can also be called user equipment (UE).

2.AMF选择用于定位的LMF。2.AMF selects the LMF for positioning.

3.AMF向选择的LMF发送Nlmf_Location_UPConfig请求。3.AMF sends a Nlmf_Location_UPConfig request to the selected LMF.

4.LMF向AMF发送Namf_Communication_N1N2MessageTransfer消息，该消息中可以包括用户面信息(User Plane Information)。4.LMF sends a Namf_Communication_N1N2MessageTransfer message to AMF, which may include user plane information (User Plane Information).

5.AMF向终端发送下行链路非接入层传输(downlink non-access stratum，DL NAS TRANSPORT)消息，该DL NAS TRANSPORT消息中包括提供定位业务的LMF的用户面信息。5.AMF sends a downlink non-access stratum (DL NAS TRANSPORT) message to the terminal. The DL NAS TRANSPORT message includes the user plane information of the LMF that provides the positioning service.

6.终端基于LMF的用户面信息通过域名服务器(domain name server，DNS)解析以发现LMF，并与所发现的LMF建立安全UP连接。6. The terminal resolves the user plane information of LMF through the domain name server (DNS) to discover LMF and establishes a secure UP connection with the discovered LMF.

7.LMF向AMF发送Nlmf_Location_UPConfig响应。7.LMF sends a Nlmf_Location_UPConfig response to AMF.

8.LMF存储定位服务(Location Service，LCS)UP连接上下文。8.LMF stores the Location Service (LCS) UP connection context.

9.经由用户面连接实现定位服务。 9. Positioning services are implemented via user plane connection.

由上述方法可知，LMF会充当用户面定位过程中的应用服务器以实现定位，可选地，该LMF会执行上述第2步以选择AMF，并且AMF会向终端发送该所选择的LMF相关的用户面信息。可选地，终端会执行上述第6步以基于用户面信息通过DNS解析发现LMF，并与所发现的LMF建立用户面连接。由此可知，在上述的“5GCN与终端之间通过用户面连接实现定位”的方法之中，AMF和终端会分别用两种不同的逻辑来确定LMF，则可能会导致错位。例如，可能使得AMF选择的LMF与终端通过DNS解析的LMF不同，从而可能会导致定位出现误差，由此，该“5GCN与终端之间通过用户面连接实现定位”的方法在通过用户面传输数据时会存在上述的缺陷，除此之外，由于LMF也不支持感知处理，从而使得该方法也无法用于提供感知业务。It can be seen from the above method that LMF will act as an application server in the user plane positioning process to achieve positioning. Optionally, the LMF will execute the above step 2 to select AMF, and AMF will send the user plane information related to the selected LMF to the terminal. Optionally, the terminal will execute the above step 6 to discover LMF through DNS resolution based on the user plane information, and establish a user plane connection with the discovered LMF. It can be seen that in the above-mentioned method of "realizing positioning through user plane connection between 5GCN and the terminal", AMF and the terminal will use two different logics to determine LMF respectively, which may cause misalignment. For example, the LMF selected by AMF may be different from the LMF resolved by the terminal through DNS, which may cause positioning errors. Therefore, the method of "realizing positioning through user plane connection between 5GCN and the terminal" will have the above-mentioned defects when transmitting data through the user plane. In addition, since LMF does not support perception processing, this method cannot be used to provide perception services.

因此，亟需一种通过用户面连接提供感知业务的方法。Therefore, there is an urgent need for a method for providing a sensing service through a user plane connection.

图2A是根据本公开实施例示出的用户面连接建立方法的交互示意图。如图2A所示，本公开实施例涉及用户面连接建立方法，用于通信系统100，上述方法包括：FIG2A is an interactive schematic diagram of a method for establishing a user plane connection according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a method for establishing a user plane connection, which is used in a communication system 100, and the method includes:

步骤2101、终端向第一网元发送会话建立请求。Step 2101: The terminal sends a session establishment request to the first network element.

在一些实施例之中，该会话建立请求可以用于请求建立第一业务的协议数据单元(Protocol Data Unit，PDU)会话，示例的，该会话建立请求例如可以为PDU会话建立请求(PDU Session Establishment Request)，可选地，该PDU会话可以用于第一业务。可选地，该第一业务可以为任一业务，例如该第一业务可以为感知业务，或者，除感知业务之外的其他业务，本公开对此不作限定。In some embodiments, the session establishment request may be used to request the establishment of a protocol data unit (PDU) session of a first service. For example, the session establishment request may be a PDU session establishment request. Optionally, the PDU session may be used for the first service. Optionally, the first service may be any service, for example, the first service may be a perception service, or other services except the perception service, which is not limited in the present disclosure.

在一些实施例之中，终端可以向第一网元发送该会话建立请求，该第一网元可以接收该会话建立请求。该第一网元用于提供会话管理功能，例如第一网元可以为SMF。在一些实施例之中，终端可以通过第六网元向第一网元发送会话建立请求，该第六网元例如可以为AMF。当终端通过第六网元发送该会话建立请求时，终端可以先向第六网元发送会话建立请求，之后，第六网元可以调用Nsmf_PDUSession_CreateSMContext Request service(Nsmf_PDU会话建立上下文请求服务)来向第一网元发送该会话建立请求。需要说明的是，当第六网元调用了Nsmf_PDUSession_CreateSMContext Request service向第一网元发送该会话建立请求后，该第一网元可以调用Nsmf_PDUSession_CreateSMContext Response service(Nsmf_PDU会话建立上下文响应服务)来向第六网元响应上述的Nsmf_PDUSession_CreateSMContext Request service，例如，可以是当第一网元决定基于该会话建立请求进行后续处理，向第六网元调用Nsmf_PDUSession_CreateSMContext Response service。In some embodiments, the terminal may send the session establishment request to the first network element, and the first network element may receive the session establishment request. The first network element is used to provide a session management function, for example, the first network element may be an SMF. In some embodiments, the terminal may send the session establishment request to the first network element through a sixth network element, and the sixth network element may be an AMF, for example. When the terminal sends the session establishment request through the sixth network element, the terminal may first send the session establishment request to the sixth network element, and then the sixth network element may call Nsmf_PDUSession_CreateSMContext Request service (Nsmf_PDU session establishment context request service) to send the session establishment request to the first network element. It should be noted that, after the sixth network element calls the Nsmf_PDUSession_CreateSMContext Request service to send the session establishment request to the first network element, the first network element can call the Nsmf_PDUSession_CreateSMContext Response service (Nsmf_PDU session establishment context response service) to respond to the above-mentioned Nsmf_PDUSession_CreateSMContext Request service to the sixth network element. For example, when the first network element decides to perform subsequent processing based on the session establishment request, it may call the Nsmf_PDUSession_CreateSMContext Response service to the sixth network element.

在一些实施例之中，该会话建立请求可以包括以下至少之一：In some embodiments, the session establishment request may include at least one of the following:

In this case, the DNN/S-NSSAI in the session establishment request corresponds to the data network on which the first service pair is deployed.

Optionally, the second network element may be used to provide the above-mentioned first service. For example, when the above-mentioned first service is a perception service, the second network element may be a SF network element. The second network element may also be a network element within the core network that provides other services, such as a location management network element (Location Management Function, LMF) for positioning services, network elements of other core networks that provide new services, etc.

在一些实施例之中，第一网元可以基于终端标识从第三网元中查询终端的签约数据。In some embodiments, the first network element may query the subscription data of the terminal from the third network element based on the terminal identifier.

Optionally, the first indication may be used to indicate that the terminal requires the second network element to provide a first service. The target second network element may be a network element that provides the first service to the terminal. The network element identifier may be, for example, a network element identifier (Identity, ID). For example, when the target second network element is a SF network element, the network element identifier may be a SF ID.

在一些实施例之中，上述步骤2102可以为可选步骤，在一些实施例之中，当第一网元中不存在该终端的签约数据时，第一网元会从第三网元中查询终端的签约数据，当第一网元中存在该终端的签约数据时，则无需执行步骤2102而直接执行步骤2103。In some embodiments, the above step 2102 may be an optional step. In some embodiments, when the contract data of the terminal does not exist in the first network element, the first network element will query the contract data of the terminal from the third network element. When the contract data of the terminal exists in the first network element, there is no need to execute step 2102 and step 2103 is executed directly.

步骤2103、第一网元确定终端需与第二网元建立用户面连接。Step 2103: The first network element determines that the terminal needs to establish a user plane connection with the second network element.

For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and step S2103 may be implemented as an independent embodiment, but is not limited thereto.

可选地，上述步骤2102为可选性步骤，其可以可选性地执行或不执行。 Optionally, the above step 2102 is an optional step, which can be optionally executed or not executed.

在本实施方式或实施例中，在不矛盾的情况下，各步骤可以独立、任意组合或交换顺序，可选方式或可选例可以任意组合，且可以与其他实施方式或其他实施例的任意步骤之间进行任意组合。In this implementation mode or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementation modes or other examples.

在一些实施例之中，在执行上述步骤2103、步骤2104之前，第一网元可能已存储了第二网元的相关信息，例如本地配置存储的第二网元或者之前相关业务时选择并存储的第二网元，可选地，该终端也可能也已与第一网元已存储的第二网元建立了连接，例如，终端可能已与该第一网元已存储的第二网元建立了控制面连接或用户面连接。基于此，当执行了上述步骤2103时，即：第一网元确定终端需与第二网元建立用户面连接，该第一网元可以先确定其已存储的第二网元是否可用，当该已存储的第二网元可用时，如：当终端已与或者能与该已存储的第二网元之间建立用户面连接且该用户面连接可用时，则第一网元在执行上述步骤2104时可以直接将该已存储的第二网元确定为上述的目标第二网元。之后，可选地，第一网元在执行上述步骤2106时，当该已存储的第二网元还未指示给终端时，则第一网元需要执行步骤2106以将该已存储的第二网元指示给终端，或者，当该已存储的第二网元已经指示给终端时，则第一网元可以可选性地执行步骤2106，即：第一网元可以不执行步骤2106，或者，第一网元可以执行步骤2106以重新将该已存储的第二网元指示给终端用于第一业务。可选地，在执行了步骤2106之后，若终端未与该已存储的第二网元建立用户面连接，则可以接着执行上述步骤2107和2108以实现第一业务；若终端已与该已存储的第二网元建立了用户面连接，则终端可以无需再执行上述的步骤2107，而可以直接执行步骤2108，以基于其与该已存储的第二网元已经建立的用户面连接来实现第一业务。In some embodiments, before executing the above steps 2103 and 2104, the first network element may have stored relevant information of the second network element, such as a second network element stored in a local configuration or a second network element selected and stored during a previous related service. Optionally, the terminal may have also established a connection with the second network element stored by the first network element. For example, the terminal may have established a control plane connection or a user plane connection with the second network element stored by the first network element. Based on this, when the above step 2103 is executed, that is, the first network element determines that the terminal needs to establish a user plane connection with the second network element, the first network element can first determine whether the second network element it has stored is available. When the stored second network element is available, such as when the terminal has established a user plane connection with or can establish a user plane connection with the stored second network element and the user plane connection is available, the first network element can directly determine the stored second network element as the above target second network element when executing the above step 2104. Afterwards, optionally, when the first network element executes the above step 2106, if the stored second network element has not been indicated to the terminal, the first network element needs to execute step 2106 to indicate the stored second network element to the terminal, or, when the stored second network element has been indicated to the terminal, the first network element can optionally execute step 2106, that is, the first network element may not execute step 2106, or the first network element may execute step 2106 to re-indicate the stored second network element to the terminal for the first service. Optionally, after executing step 2106, if the terminal has not established a user plane connection with the stored second network element, the above steps 2107 and 2108 may be executed to implement the first service; if the terminal has established a user plane connection with the stored second network element, the terminal may not need to execute the above step 2107 again, but may directly execute step 2108 to implement the first service based on the user plane connection that has been established with the stored second network element.

在一些实施例之中，若上述的已存储的第二网元不可用，例如终端与该已存储的第二网元之间不是用户面连接或者该已存储的第二网元不满足当前请求的第一业务需求或者服务范围时，第一网元可以执行上述步骤2104以对第二网元进行重选，并选择出上述步骤2104中的目标第二网元，接着执行后续步骤2105-2108，以使得终端成功与目标第二网元建立用户面连接并实现第一业务。In some embodiments, if the above-mentioned stored second network element is not available, for example, there is no user plane connection between the terminal and the stored second network element or the stored second network element does not meet the first service requirement or service scope of the current request, the first network element can execute the above-mentioned step 2104 to reselect the second network element, and select the target second network element in the above-mentioned step 2104, and then execute subsequent steps 2105-2108, so that the terminal successfully establishes a user plane connection with the target second network element and realizes the first service.

可选地，在另一些实施例之中，在执行上述步骤2103、步骤2104之前，第一网元中可能未存储有第二网元，此时，当执行了上述步骤2103时，即：第一网元确定终端需与第二网元建立用户面连接，第一网元可以接着执行上述步骤2104以选择出上述步骤2104中的目标第二网元，并在执行目标第二网元选择的时候额外考虑是否支持用户面连接提供第一业务，之后，可以接着执行后续步骤2105-2108，以使得终端成功与目标第二网元建立用户面连接并实现第一业务。Optionally, in some other embodiments, before executing the above steps 2103 and 2104, the second network element may not be stored in the first network element. In this case, when the above step 2103 is executed, that is, the first network element determines that the terminal needs to establish a user plane connection with the second network element, the first network element can then execute the above step 2104 to select the target second network element in the above step 2104, and when executing the target second network element selection, additionally consider whether the user plane connection is supported to provide the first service. After that, subsequent steps 2105-2108 can be executed to enable the terminal to successfully establish a user plane connection with the target second network element and realize the first service.

For example, step S5101 may be implemented as an independent embodiment, and step S5102 may be implemented as an independent embodiment, but is not limited thereto.

以下为对上述方法的示例性介绍。The following is an exemplary introduction to the above method.

本公开实施例提供一种通过用户面支持感知业务的方法，包括: The embodiment of the present disclosure provides a method for supporting a perception service through a user plane, including:

-建立用于感知服务的PDU会话，并且SMF选择支持感知功能(SF)的NF。- A PDU session for the sensing service is established and the SMF selects a NF that supports the sensing function (SF).

-在UE和SF之间建立用户面连接。- Establish a user plane connection between the UE and the SF.

在UE和SF之间交换感知信息。The perception information is exchanged between the UE and the SF.

假设5GC内支持感知功能的NF为SF，感知业务由UE发起。感知信息处理可以在UE或SF中完成。感知信息可以由SF从RAN或UE收集，或者，感知信息可以由UE从其他UE或对象或RAN收集。感知服务可以由UE或网络或AF触发。Assume that the NF supporting the perception function in 5GC is SF, and the perception service is initiated by UE. Perception information processing can be completed in UE or SF. Perception information can be collected by SF from RAN or UE, or, perception information can be collected by UE from other UEs or objects or RAN. Perception service can be triggered by UE or network or AF.

在该实施例中，专用DNN/S-NSSAI被部署用于感知服务。In this embodiment, a dedicated DNN/S-NSSAI is deployed for perception services.

图5B是根据本公开实施例示出的用户面连接建立方法的流程示意图，如图5B所示，该方法可以包括以下步骤：FIG5B is a schematic diagram of a method for establishing a user plane connection according to an embodiment of the present disclosure. As shown in FIG5B , the method may include the following steps:

0、感知服务由UE/CN/AF触发，UE确定或从CN或应用获得指示，指示UE和SF之间需要通过用户面进行数据交换或者指示UE和SF之间需要建立会话进行数据交换。其中，第0步图5B中未示出。0. The sensing service is triggered by the UE/CN/AF, and the UE determines or obtains an indication from the CN or application, indicating that data needs to be exchanged between the UE and the SF through the user plane or that a session needs to be established between the UE and the SF for data exchange. Step 0 is not shown in FIG. 5B .

1、UE向感知服务专用的DNN/S-NSSAI发起PDU会话建立请求(PDU Session Establishment Request)，该请求可以在本地配置，也可以通过URSP规则配置。1. The UE initiates a PDU session establishment request (PDU Session Establishment Request) to the DNN/S-NSSAI dedicated to the perception service. The request can be configured locally or through URSP rules.

2、AMF调用Nsmf_PDU Session_CreateSMContext请求服务向smf发送PDU会话建立请求。2. AMF calls Nsmf_PDU Session_CreateSMContext request service to send a PDU session establishment request to smf.

3、SMF调用Nsmf_PDU session_CreateSMContext响应服务。3. SMF calls Nsmf_PDU session_CreateSMContext response service.

4、SMF检索其会话管理签约数据。SF选择信息可以包括在签约数据中，SF选择信息可以是需要SF的指示，和/或SF ID(The SMF retrieves Session Management Subscription data for corresponding SUPI,DNN and S-NSSAI if it is not available.The SF selection information may be included in the Subscription data,the SF selection information can be the indication that SF is required,and/or the SF ID)。4. The SMF retrieves Session Management Subscription data. The SF selection information may be included in the Subscription data, the SF selection information can be the indication that SF is required, and/or the SF ID.

5、SMF基于为感知业务定义的策略例如针对该UE接入感知业务对应的DNN/S-NSSAI的策略和/或在步骤3中接收的签约数据，决定需要到SF的用户面连接。5. The SMF determines the need for a user plane connection to the SF based on the policy defined for the perception service, such as the DNN/S-NSSAI policy corresponding to the UE accessing the perception service and/or the subscription data received in step 3.

6、SMF经由NRF或基于在步骤3中接收的签约数据来确定SF。如果SF是通过NRF确定的，那么SF应该在NRF注册，并且SMF调用Nnrf_NFDiscovery服务用于SF发现。6. SMF determines the SF via NRF or based on the subscription data received in step 3. If the SF is determined by NRF, then the SF shall be registered with NRF and SMF invokes Nnrf_NFDiscovery service for SF discovery.

7、N4会话被建立/修改以在5GC内建立用户面连接，用于通过用户面连接SF。7. The N4 session is established/modified to establish a user plane connection within the 5GC for connecting the SF through the user plane.

8、SMF经由AMF向UE发送带有在步骤6中确定的SF信息的PDU会话建立接受(PDU Session Establishment Accept)。8. SMF sends a PDU Session Establishment Accept (PDU Session Establishment Accept) with the SF information determined in step 6 to the UE via AMF.

9、UE和SF之间的用户面连接建立完成，包括现有PDU会话建立过程中的其他步骤。9. The user plane connection between the UE and the SF is established, including other steps in the existing PDU session establishment process.

10、UE和SF之间通过用户面交换的带有感知参数的感知服务请求。该感知参数可以为前述的感知数据；10. A perception service request with perception parameters exchanged between the UE and the SF via the user plane. The perception parameters may be the aforementioned perception data;

11、SF从RAN收集感知信息，该感知信息可以为前述的感知数据。11. SF collects perception information from RAN, and the perception information may be the aforementioned perception data.

12、如果在SF中处理感知信息，则在处理感知信息之后，将感知服务的输出交付给UE，否则，可以将感知信息发送给UE。如果UE收集了感知信息，则如果需要，感知信息从UE发送到SF。12. If the perception information is processed in the SF, the output of the perception service is delivered to the UE after processing the perception information, otherwise, the perception information may be sent to the UE. If the UE collects the perception information, the perception information is sent from the UE to the SF if necessary.
