具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本申请的一实施方式涉及一种用户报文转发的方法，应用于用户面功能UPF网元，具体流程如图1所示。
在本实施方式中，用户面功能UPF网元接收用户设备UE发送的用户报文；根据UE与客户终端设备CPE的关联关系，确定与发送所述用户报文的UE关联的CPE；获取所述确定的CPE的控制转发策略，并基于获取的所述CPE的控制转发策略转发所述用户报文。
本实施方式应用的场景可以如图2所示。在5G LAN中，UPF网元在SMF网元的指示下进行CPE1与CPE2的通信，利用UPF网元内嵌的LocalSwitch功能实现CPE1与CPE2之间报文的互相转发。如图2所示，CPE1与CPE2可以分别下挂多个UE,这种下挂在CPE下的UE发送的用户报文如何进行传输，现有的5G LAN尚未给出解决方案。
下面对本实施例中的用户报文转发的方法的实现细节进行具体的说明，以下内容仅为方便理解本方案的实现细节，并非实施本方案的必须。具体流程如图1所示，可包括如下步骤：
步骤101，接收用户设备UE发送的用户报文。
在本步骤中，UPF网元接收UE发送的用户报文，发送用户报文的用户设备可能是直接接入5G LAN的用户设备，也可能是通过CPE接入5G LAN的用户设备，即下挂在CPE的用户设备。
步骤102，根据UE与客户终端设备CPE的关联关系，确定与发送用户报文的UE关联的CPE。
在本步骤中，对于下挂在CPE的用户设备发出的用户报文，UPF网元根据UE与客户终端设备CPE的关联关系，确定发送该用户报文的UE关联的具体CPE。其中，本步骤中涉及的UE与客户终端设备CPE的关联关系可以通过多种方式获取。
在一个例子中，UPF网元在所述接收用户设备UE发送的用户报文之前，还可以预先在本地配置所述关联关系。在本例中，步骤102可以是，根据预先在本地配置的所述关联关系，确定与发送所述用户报文的UE关联的CPE。在本例中，UPF网元在接收到用户报文时，能够根据预先在本地配置的关联关系，确定发送该用户报文的UE关联的CPE。
步骤103，获取确定的CPE的控制转发策略，并基于获取的CPE的控制转发策略转发用户报文。
在本步骤中，UPF网元获取在步骤102中确定的CPE的控制转发策略，并基于该控制转发策略转发接收到的用户报文。具体可以是，将用户报文基于该控制转发策略转发至另一直接接入5G LAN的CPE，进而转发至该CPE下挂的另一用户设备。
在一个例子中，UPF网元在所述接收用户设备UE发送的用户报文之前，还可以接收并响应会话管理功能SMF网元发送的会话请求；其中，所述会话请求中携带有所述关联关系。在本例中，步骤102可以是，根据在所述会话请求中解析得到的所述关联关系，确定与发送所述用户报文的UE关联的CPE。在本例中，UPF网元能够在接收到的会话请求中解析出UE与CPE的关联关系，使得在接收到用户报文时，能够根据关联关系确定发送该用户报文的UE关联的CPE。
本例涉及的交互流程图可以如图3所示。SMF网元首先获取UE与CPE的关联关系，进而将该关联关系携带在会话请求中发送给UPF网元，此处涉及的会话请求可以是会话建立请求N4 Session Establishment Request或会话更新请求N4 Session Modification Request。UPF网元在接收到会话请求后，在该会话请求中解析出上述关联关系，进而可以进行5G LAN组内用户设备的接入。随后，UPF网元可以通过向SMF网元回复会话响应的方式，响应其发送的会话请求。此处涉及的会话响应可以是N4 Session Establishment Response。
在接收到用户设备UE(A)发出的用户报文后，UPF网元根据在所述会话请求中解析得到的所述关联关系，确定与发送该用户报文的UE(A)关联的CPE为CPE(1)。于是，UPF网元获取CPE(1)的控制转发策略，并基于CPE(1)的控制转发策略转发UE(A)发出的用户报文。值得一提的是，此处UPF网元转发下挂在CPE下的用户设备发出的用户报文，与转发直接接入5G LAN的用户设备发出的用户报文相同，均是基于内嵌在UPF网元中的LocalSwitch功能实现的。
UE(A)发出的用户报文被UPF网元转发至与用户报文的目标用户设备UE(B)关联的CPE(2)，进而被转发至目标用户设备UE(B)。若接收到用户设备UE(B)发出的响应用户报文，则UPF网元依照相同的处理逻辑和步骤将下挂在CPE(2)的UE(B)发出的响应用户报文经过与用户报文的目标用户设备UE(A)关联的CPE(1)，转发至目标用户设备UE(A)。
在另一个例子中，UPF网元接收到的用户报文中封装有发送所述用户报文的UE的信息以及与所述UE关联的CPE的信息，UPF网元解析出所述UE以及所述CPE的信息；将所述UE以及所述CPE的信息携带在会话上报请求中发送给SMF网元，供SMF网元更新所述关联关系。
本例涉及的交互流程图可以如图4所示。在本例中，UPF网元接收到的UE(A)发送的用户报文，并在该用户报文中解析出UE(A)以及CPE(1)的信息后，可以发送一携带有此组关联的UE以及CPE的信息的会话上报请求给SMF网元，此处涉及的会话上报请求可以是N4 Session Report Request。SMF网元在接收到会话上报请求后，在该会话上报请求中解析出上述关联关系，并向UPF网元回复一会话上报响应消息，此会话上报响应可以是N4 Session Report Response。
SMF网元将在会话上报请求中解析出的UE(A)与CPE(1)关联关系更新到在SMF网元本地存储并维护的关联关系中，并发送一携带更新的关联关系的会话更新请求给UPF网元，此处涉及的会话更新请求可以是N4 Session Modification Request。UPF网元在接收到的会话更新请求中解析出更新的关联关系，并向SMF网元回复一会话更新响应消息，此会话更新响应可以是N4 Session Modification Response。
UPF网元获取CPE(1)的控制转发策略，并基于CPE(1)的控制转发策略转发UE(A)发出的用户报文。UE(A)发出的用户报文被UPF网元转发至与用户报文的目标用户设备UE(B)关联的CPE(2)，进而被转发至目标用户设备UE(B)。若接收到用户设备UE(B)发出的响应用户报文，则UPF网元依照相同的处理逻辑和步骤将下挂在CPE(2)的UE(B)发出的响应用户报文经过与用户报文的目标用户设备UE(A)关联的CPE(1)，转发至目标用户设备UE(A)。在本例中，可以无需预先进行关联关系的配置，仅动态获取关联关系，具有灵活性高的优势。
在本实施方式中，UPF网元接收用户设备UE发送的用户报文，并根据UE与客户终端设备CPE的关联关系，确定与发送所述用户报文的UE关联的CPE。即UPF能够获知发送用户报文的用户设备下挂的具体CPE。进而UPF网元获取确定的CPE的控制转发策略，并基于获取的所述CPE的控制转发策略转发用户报文。在发送用户报文的用户设备下挂在CPE下时，UPF能够获取该用户设备关联的CPE，并基于该CPE的控制转发策略将用户报文转发出去。使得下挂在CPE下的用户设备发出的用户报文能够被正常转发，即能够实现下挂在CPE下的用户设备的通信传输。
本申请的一实施方式涉及一种用户报文转发的方法，应用于用户面功能UPF网元。
在本实施方式中，会话管理功能SMF网元，向UPF网元发送携带有UE与CPE的关联关系 的会话请求，供所述UPF网元在接收UE发送的用户报文后，根据所述关联关系，确定与发送所述用户报文的UE关联的CPE，并获取所述确定的CPE的控制转发策略；指示所述UPF网元基于获取的所述CPE的控制转发策略转发所述用户报文。
下面对本实施例中的用户报文转发的方法的实现细节进行具体的说明，以下内容仅为方便理解本方案的实现细节，并非实施本方案的必须。具体流程如图5所示，可包括如下步骤：
步骤201，向UPF网元发送携带有UE与CPE的关联关系的会话请求，供所述UPF网元在接收UE发送的用户报文后，根据所述关联关系，确定与发送所述用户报文的UE关联的CPE，并获取所述确定的CPE的控制转发策略。
在本步骤中，SMF网元向UPF网元发送会话请求，该会话请求中携带有SMF网元中存储的UE与CPE的关联关系。对于SMF网元，可以通过以下任一方式获取UE与CPE的关联关系：预先在本地配置所述关联关系；获取统一数据管理网元UDM签约的所述关联关系；获取鉴权授权计费服务器AAA授权的所述关联关系。本步骤中涉及的会话请求可以是会话建立请求N4 Session Establishment Request或会话更新请求N4 Session Modification Request。
本领域的技术人员应该可以理解，在SMF网元获取统一数据管理网元UDM签约的所述关联关系的情况下，UDM会预先签约CPE与下挂的一组用户设备的关联关系，进而与SMF网元进行消息的交互，实现SMF网元获取统一数据管理网元UDM签约的所述关联关系。在SMF网元获取鉴权授权计费服务器AAA授权的所述关联关系的情况下，AAA会预先授权CPE与下挂的一组IP终端关联关系，进而与SMF进行鉴权消息的交互，实现SMF网元获取鉴权授权计费服务器AAA授权的所述关联关系。
值得一提的是，本实施方式中涉及的SMF网元获取UE与CPE的关联关系的三种方式，以及上一实施方式中涉及的UPF网元预先在本地配置关联关系这一技术手段，可以被归类为获取关联关系的静态配置方式。在静态配置方式中，通信流程简单，可以减少网元之间的消息交互，能够有效降低系统消耗。
相比上述的获取关联关系的静态配置方式，UPF网元在接收到封装有发送用户报文的UE的信息以及与UE关联的CPE的信息的用户报文时，向SMF网元主动上报UE与CPE的关联关系的方式，可以理解为主动学习方式。主动学习方式相比上述静态配置方式，消息交互流程会较为复杂，增加信令开销。但实施这种获取关联关系的方式，可以无需预先整网规划数据，仅动态获取关联关系，具有灵活性高，网元之间的依赖性低的优势。
步骤202，指示所述UPF网元基于获取的所述CPE的控制转发策略转发所述用户报文。
在本步骤中，UPF网元已确定接收到的用户报文所属的用户设备关联的CPE，SMF网元能够指示UPF网元基于该CPE的控制转发策略转发所述用户报文。
在本实施方式中，SMF网元向UPF网元发送携带有UE与CPE的关联关系的会话请求，使得UPF网元在接收到会话请求能够获取其中携带的UE与CPE的关联关系。且使得UPF网元在接收UE发送的用户报文后，能够根据该关联关系，确定与发送用户报文的UE关联的CPE，并获取确定的CPE的控制转发策略。SMF网元进而指示UPF网元基于获取的CPE的控制转发策略转发用户报文。能够使得下挂在CPE下的用户设备发出的用户报文能够被正常转发，即能够实现下挂在CPE下的用户设备的通信传输。
本申请的一实施方式涉及一种UPF网元，如图6所示，包括：
接收模块301，用于接收用户设备UE发送的用户报文；
确定模块302，用于根据UE与客户终端设备CPE的关联关系，确定与发送所述用户报文的UE关联的CPE；
转发模块303，用于获取所述确定的CPE的控制转发策略，并基于获取的所述CPE的控制转发策略转发所述用户报文。
在一个例子中，接收模块301，还可以用于在接收用户设备UE发送的用户报文之前，接收并响应会话管理功能SMF网元发送的会话请求。在本例中，确定模块302，可以用于根据在所述会话请求中解析得到的所述关联关系，确定与发送所述用户报文的UE关联的CPE。
在另一个例子中，UPF网元还可以包括：预先配置模块(图中未示出)，用于在接收用户设备UE发送的用户报文之前，预先在本地配置所述关联关系。在本例中，确定模块302，可以用于根据预先在本地配置的所述关联关系，确定与发送所述用户报文的UE关联的CPE。
在一个例子中，UPF网元还可以包括：上报模块(图中未示出)，用于在接收到的用户报文中封装有发送所述用户报文的UE的信息以及与所述UE关联的CPE的信息时，解析出所述UE以及所述CPE的信息；将所述UE以及所述CPE的信息携带在会话上报请求中发送给SMF网元，供SMF网元更新所述关联关系。
本实施方式提供的UPF网元接收用户设备UE发送的用户报文，并根据UE与客户终端设备CPE的关联关系，确定与发送所述用户报文的UE关联的CPE。即UPF能够获知发送用户报文的用户设备下挂的具体CPE。进而UPF网元获取确定的CPE的控制转发策略，并基于获取的所述CPE的控制转发策略转发用户报文。在发送用户报文的用户设备下挂在CPE下时，UPF能够获取该用户设备关联的CPE，并基于该CPE的控制转发策略将用户报文转发出去。使得下挂在CPE下的用户设备发出的用户报文能够被正常转发，即能够实现下挂在CPE下的用户设备的通信传输。
本申请的另一实施方式涉及一种SMF网元，如图7所示，包括：
发送模块401，用于向UPF网元发送携带有UE与CPE的关联关系的会话请求，供所述UPF网元在接收UE发送的用户报文后，根据所述关联关系，确定与发送所述用户报文的UE关联的CPE，并获取所述确定的CPE的控制转发策略，且基于获取的所述CPE的控制转发策略转发所述用户报文；
转发管理模块402，用于指示所述UPF网元基于获取的所述CPE的控制转发策略转发所述用户报文。

本实施方式提供的SMF网元向UPF网元发送携带有UE与CPE的关联关系的会话请求，使得UPF网元在接收到会话请求能够获取其中携带的UE与CPE的关联关系。且使得UPF网元在接收UE发送的用户报文后，能够根据该关联关系，确定与发送用户报文的UE关联的CPE，并获取确定的CPE的控制转发策略。SMF网元进而指示UPF网元基于获取的CPE的控制转发策略转发用户报文。能够使得下挂在CPE下的用户设备发出的用户报文能够被正常转发，即能够实现下挂在CPE下的用户设备的通信传输。
值得一提的是，本申请上述实施方式中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单 元的组合实现。此外，为了突出本申请的创新部分，本实施方式中并没有将与解决本申请所提出的技术问题关系不太密切的单元引入，但这并不表明本实施方式中不存在其它的单元。
