技术领域technical field
本申请涉及移动通信技术领域，尤其涉及一种通信方法及装置。The present application relates to the technical field of mobile communication, and in particular to a communication method and device.
背景技术Background technique
目前，第三代合作伙伴项目(3rd generation partnership project，3GPP)中定义了一个第五代移动通信技术(5 th-generation，5G)局域网(local area network，LAN)对应一个数据网络名称(data network name，DNN)和单一网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)组合，也就是说，可以通过DNN和S-NSSAI的组合来标识5G LAN组。 Currently, the 3rd generation partnership project (3rd generation partnership project, 3GPP) defines a 5th generation mobile communication technology (5 th -generation, 5G) local area network (local area network, LAN) corresponding to a data network name (data network name, DNN) and single network slice selection assistance information (single network slice selection assistance information, S-NSSAI), that is, the 5G LAN group can be identified through the combination of DNN and S-NSSAI.
5G LAN一般应用于面向企业(to business，toB)场景。在toB场景下，5G LAN组的规划由企业进行。当企业增加或删除5G LAN组时，企业必须通知运营商维护人员增加或删除该5G LAN组对应的DNN和S-NSSAI组合，同时需要数据网络认证、授权和计费(data network authentication,authorization and accounting，DN-AAA)服务器维护5G LAN组对应的DNN和S-NSSAI组合，因此同一份5G LAN组配置信息(本申请中简称为5G LAN配置信息)需要在两个***中维护。此外，UE归属于哪个5G LAN组(或DNN和S-NSSAI组合)需要在统一数据管理功能(unified data management，UDM)中签约，如果UE更改归属的5G LAN组，需要在UDM中变更签约信息。5G LAN is generally used in business-oriented (to business, toB) scenarios. In the toB scenario, the planning of the 5G LAN group is carried out by the enterprise. When an enterprise adds or deletes a 5G LAN group, the enterprise must notify the operator's maintenance personnel to add or delete the combination of DNN and S-NSSAI corresponding to the 5G LAN group. At the same time, data network authentication, authorization and billing (data network authentication, authorization and accounting, DN-AAA) server maintains the DNN and S-NSSAI combination corresponding to the 5G LAN group, so the same 5G LAN group configuration information (referred to as 5G LAN configuration information in this application) needs to be maintained in two systems. In addition, which 5G LAN group (or DNN and S-NSSAI combination) the UE belongs to needs to be signed in the unified data management function (unified data management, UDM). If the UE changes the 5G LAN group it belongs to, it needs to change the signing information in UDM .
以上5G LAN组的管理方式存在5G LAN配置信息管理不便的问题。The management method of the above 5G LAN group has the problem of inconvenient management of 5G LAN configuration information.
发明内容Contents of the invention
本申请提供一种通信方法及装置，用以提供5G LAN配置信息的管理效率。This application provides a communication method and device to improve the management efficiency of 5G LAN configuration information.
第一方面，本申请提供一种通信方法，该方法可由统一数据库或统一数据库中的芯片或模块等组件实施。以统一数据库是UDR为例，该方法可包括如下过程：UDR接收来自于NEF的第一消息，所述第一消息包括5G LAN配置信息、S-NSSAI和DNN；UDR还可存储所述5G LAN配置信息、所述S-NSSAI和所述DNN之间的对应关系。In a first aspect, the present application provides a communication method, which can be implemented by a unified database or components such as chips or modules in the unified database. Taking the unified database as UDR as an example, the method may include the following process: UDR receives the first message from NEF, the first message includes 5G LAN configuration information, S-NSSAI and DNN; UDR can also store the 5G LAN The corresponding relationship among the configuration information, the S-NSSAI and the DNN.
采用该方法，UDR可实现支持根据S-NSSAI和DNN查询5G LAN配置信息，不再需要企业人员将5G LAN配置信息存储到UDM中，可实现5G LAN配置信息的高效管理。Using this method, UDR can support querying 5G LAN configuration information based on S-NSSAI and DNN, and no longer requires enterprise personnel to store 5G LAN configuration information in UDM, which can realize efficient management of 5G LAN configuration information.
在一种可能的实现方式中，UDR还可向NRF发送第二消息，所述第二消息用于指示所述UDR与所述S-NSSAI和所述DNN之间的对应关系。例如，UDR可请求NRF存储UDR与S-NSSAI和DNN之间的对应关系，以便NRF可以根据S-NSSAI和DNN寻址UDR。In a possible implementation manner, the UDR may further send a second message to the NRF, where the second message is used to indicate the correspondence between the UDR, the S-NSSAI, and the DNN. For example, UDR may request NRF to store the correspondence between UDR and S-NSSAI and DNN, so that NRF can address UDR according to S-NSSAI and DNN.
在一种可能的实现方式中，UDR还可向SMF发送所述5G LAN配置信息、所述S-NSSAI和所述DNN。采用该方式，UDR可向SMF发送5G LAN配置信息、所述S-NSSAI 和所述DNN，用于SMF确定与该S-NSSAI和该DNN相关联的会话，并根据5G LAN配置信息确定是否更新该会话在UPF侧的隧道参数。此外，SMF可根据来自于UDR的5G LAN配置信息配置与该S-NSSAI和该DNN相关联的会话的5G LAN信息，因此不需要SMF像现有技术一样通过二次鉴权过程从DN-AAA中获取5G LAN配置信息响应的工作参数，也就不需要DN-AAA维护5G LAN配置信息，避免在运营商网络和DN-AAA两个***中同时维护5G LAN配置信息，可提高5GLAN配置信息管理的可靠性。In a possible implementation manner, the UDR may also send the 5G LAN configuration information, the S-NSSAI and the DNN to the SMF. In this way, the UDR can send the 5G LAN configuration information, the S-NSSAI and the DNN to the SMF, for the SMF to determine the session associated with the S-NSSAI and the DNN, and determine whether to update it according to the 5G LAN configuration information Tunnel parameters of the session on the UPF side. In addition, the SMF can configure the 5G LAN information of the session associated with the S-NSSAI and the DNN according to the 5G LAN configuration information from the UDR, so there is no need for the SMF to go through the secondary authentication process from the DN-AAA as in the prior art. In order to obtain the working parameters of the 5G LAN configuration information response, there is no need for DN-AAA to maintain 5G LAN configuration information, avoiding the simultaneous maintenance of 5G LAN configuration information in the operator network and DN-AAA two systems, which can improve the management of 5GLAN configuration information reliability.
在一种可能的实现方式中，UDR还可接收来自于所述SMF的第一请求，所述第一请求用于请求所述5G LAN配置信息，所述第一请求包括与所述5G LAN配置信息对应的S-NSSAI和DNN。例如，该第一请求可以是订阅5G LAN配置信息的变化的请求，或者是一次性的5G LAN配置信息的请求，该请求中可携带对应的S-NSSAI和DNN，以使得UDR可以根据第一请求中包括的S-NSSAI和DNN实现对相应的5G LAN配置信息的高效查询。In a possible implementation manner, the UDR may also receive a first request from the SMF, the first request is used to request the 5G LAN configuration information, and the first request includes The corresponding S-NSSAI and DNN of the information. For example, the first request may be a request for subscribing to changes in 5G LAN configuration information, or a one-time request for 5G LAN configuration information. The S-NSSAI and DNN included in the request enable efficient query of the corresponding 5G LAN configuration information.
在一种可能的实现方式中，5G LAN配置信息可包括以下信息中的至少一项：与所述S-NSSAI和所述DNN对应的5G LAN组的信息；与所述S-NSSAI和所述DNN对应的每个5G LAN组分别对应的企业侧隧道参数；UE、所述S-NSSAI和所述DNN对应的5G LAN组的信息；UE、所述S-NSSAI和所述DNN对应的工作参数。采用该方式，可提供以5G LAN组、S-NSSAI和DNN的组合，或UE、S-NSSAI和DNN的组合为粒度的多粒度的配置方式，提高配置灵活性。In a possible implementation, the 5G LAN configuration information may include at least one of the following information: information about the 5G LAN group corresponding to the S-NSSAI and the DNN; Enterprise-side tunnel parameters corresponding to each 5G LAN group corresponding to the DNN; information about the UE, the S-NSSAI, and the 5G LAN group corresponding to the DNN; working parameters corresponding to the UE, the S-NSSAI, and the DNN . Using this method, it can provide a multi-granularity configuration method based on the combination of 5G LAN group, S-NSSAI and DNN, or the combination of UE, S-NSSAI and DNN, and improve configuration flexibility.
在一种可能的实现方式中，所述5G LAN组包括新增的5G LAN组，UDR还可向所述NRF发送第二请求，所述第二请求用于请求注册所述新增的5G LAN组。UDR还可接收来自于所述NRF的所述新增的5G LAN组的标识。采用该方式，当企业通过5G LAN配置信息指示新增的5G LAN组时，UDR可向NRF请求注册该新的5G LAN组，可实现5G LAN组的灵活管理。In a possible implementation, the 5G LAN group includes a newly added 5G LAN group, and the UDR may also send a second request to the NRF, where the second request is used to request registration of the newly added 5G LAN group Group. The UDR may also receive the identifier of the newly added 5G LAN group from the NRF. In this way, when the enterprise indicates a new 5G LAN group through the 5G LAN configuration information, the UDR can request the NRF to register the new 5G LAN group, which can realize the flexible management of the 5G LAN group.
第二方面，本申请提供一种通信方法，该方法可由网络存储功能或网络存储功能中的芯片或模块等组件实施。以网络存储功能是NRF为例，该方法可包括如下过程：NRF接收来自于NEF的第三请求，所述第三请求用于请求UDR的信息，所述第三请求包括S-NSSAI和DNN，所述UDR用于存储5G LAN配置信息，所述5G LAN配置信息对应于所述S-NSSAI和所述DNN；NRF还可确定与所述S-NSSAI和所述DNN对应的所述UDR；NRF还可向所述NEF发送所述UDR的信息。In a second aspect, the present application provides a communication method, which can be implemented by a network storage function or a component such as a chip or a module in the network storage function. Taking the network storage function as an example of NRF, the method may include the following process: the NRF receives a third request from the NEF, the third request is used to request UDR information, and the third request includes S-NSSAI and DNN, The UDR is used to store 5G LAN configuration information, and the 5G LAN configuration information corresponds to the S-NSSAI and the DNN; NRF can also determine the UDR corresponding to the S-NSSAI and the DNN; NRF The information of the UDR may also be sent to the NEF.

可以理解的是，上述网元或者功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。可选的，上述网元或者功能可以由一个设备实现，也可以由多个设备共同实现，还可以是一个设备内的一个功能模块，本申请实施例对此不作具体限定。It can be understood that the above-mentioned network element or function may be a network element in a hardware device, or a software function running on dedicated hardware, or a virtualization function instantiated on a platform (for example, a cloud platform). Optionally, the foregoing network element or function may be implemented by one device, or jointly implemented by multiple devices, or may be a functional module in one device, which is not specifically limited in this embodiment of the present application.
本申请中的会话管理网元、用户面网元、移动性管理网元分别可以是图1A中的SMF、UPF、AMF，也可以是未来通信如第六代(6th generation，6G)网络中具有上述SMF、UPF、AMF的功能的网元，本申请对此不限定。在本申请的实施例中，以SMF、UPF、AMF分别作为会话管理网元、用户面网元、移动性管理网元的一个举例进行描述。The session management network element, user plane network element, and mobility management network element in this application can be the SMF, UPF, and AMF in FIG. The above-mentioned network elements with functions of SMF, UPF, and AMF are not limited in this application. In the embodiments of the present application, SMF, UPF, and AMF are respectively used as an example of a session management network element, a user plane network element, and a mobility management network element for description.
此外，服务化架构(service-based architecture，SBA)是5G网络的基础架构。服务化主要体现在控制面。SBA的本质是按照“自包含、可重用、独立管理”三原则，将网络功能定义为若干个可被灵活调用的“服务”模块。基于此，运营商可以按照业务需求进行灵活定制组网。网络功能间的交互由服务调用实现，每个网络功能对外呈现通用的服务化接口，可被授权的网络功能或服务调用。如图1B所示为5G网络的一种示例性的服务化架构示意图，该架构中，核心网网元可通过服务化接口与其他核心网网元进行通信，例如，AMF对应的服务化接口被称为Namf接口。In addition, the service-based architecture (SBA) is the basic architecture of the 5G network. Servitization is mainly reflected in the control plane. The essence of SBA is to define network functions as several "service" modules that can be flexibly invoked according to the three principles of "self-contained, reusable, and independent management". Based on this, operators can flexibly customize networking according to business needs. The interaction between network functions is realized by service calls, and each network function presents a common service-oriented interface externally, which can be called by authorized network functions or services. Figure 1B is a schematic diagram of an exemplary service-oriented architecture of a 5G network. In this architecture, core network elements can communicate with other core network elements through service-oriented interfaces. For example, the service-oriented interfaces corresponding to AMF are Called the Namf interface.
3)二次鉴权3) Second authentication
二次鉴权是终端在建立PDU会话时的一个可选的流程，它的作用是在建立PDU会话时，由3GPP网络与DN-AAA服务器交互，对用户的身份进行认证和授权。以下将DN-AAA服务器简称为DN-AAA。其中，DN-AAA可以为数据网络(DN)内，也可以位于数据网络外。The secondary authentication is an optional process for the terminal when establishing a PDU session. Its function is to authenticate and authorize the user's identity through interaction between the 3GPP network and the DN-AAA server when establishing the PDU session. Hereinafter, the DN-AAA server is referred to as DN-AAA for short. Wherein, the DN-AAA can be inside the data network (DN), or outside the data network.
4)组会话4) Group conversation
组会话又可称为组N4会话(group-level N4session)。5G LAN场景网络侧在UPF内部增加5G虚拟网络(virtual network，VN)内部(VN internal)接口，在PDU UE会话基础上增加了组N4会话(group-level N4Session)，在UPF之间增加N19接口。根据UPF收到的用户业务数据包目的地址的不同，报文可能在UPF进行本地交互发到UPF管理的目的UE，可能经过N6接口发送到DN网络侧设备，也可能经过N19(图1A未示出)或N9接口发送到其他UPF上，以便发给其他UPF管理的UE。其中，N9可用于中间UPF(intermediate UPF，I-UPF)与PDU会话锚点(PDU session anchor，PSA)UPF之间的通信，N19可用于两个PSA UPF之间的通信。A group session can also be called a group N4 session (group-level N4 session). In the 5G LAN scenario, the network side adds a 5G virtual network (virtual network, VN) internal (VN internal) interface inside the UPF, adds a group-level N4 session (group-level N4Session) on the basis of the PDU UE session, and adds an N19 interface between UPFs . Depending on the destination address of the user service data packet received by the UPF, the message may be sent to the destination UE managed by the UPF through local interaction at the UPF, may be sent to the DN network side device through the N6 interface, or may pass through the N19 (not shown in Figure 1A out) or N9 interface to other UPFs, so as to be sent to UEs managed by other UPFs. Among them, N9 can be used for communication between an intermediate UPF (intermediate UPF, I-UPF) and a PDU session anchor (PDU session anchor, PSA) UPF, and N19 can be used for communication between two PSA UPFs.
5G LAN同组内数据报文匹配转发过程如下：The matching and forwarding process of data packets in the same group of 5G LAN is as follows:
对应属于同一个5G虚拟网络组(5G VN group)内的多个UE，如果这多个UE均在同一个PSA UPF下，此场景下UPF采用本地交换完成组内UE之间的数据交换。详细过程为：UPF可通过N3口收到源UE发往目的UE的数据报文，经过包检测规则(packet detection rule，PDR)匹配后(基于报文通用无线分组业务(general packet radio service，GPRS)隧道协议(GPRS tunneling protocol，GTP)-用户平面(GTP-U)报文头完成匹配(第一轮匹配))获得源UE N4会话，对应的转发动作规则(forwarding action rule，FAR)指示将该报文转发到5G VN internal从而进入第二轮PDR匹配(基于报文中的目的IP完成匹配)，获得目的UE N4会话，对应的FAR指示将报文通过N3口转发到目的UE。Corresponding to multiple UEs belonging to the same 5G virtual network group (5G VN group), if these multiple UEs are under the same PSA UPF, in this scenario, the UPF uses local switching to complete the data exchange between UEs in the group. The detailed process is: the UPF can receive the data message sent by the source UE to the destination UE through the N3 interface, and after the packet detection rule (packet detection rule, PDR) is matched (based on the message general packet radio service (general packet radio service, GPRS ) tunneling protocol (GPRS tunneling protocol, GTP)-user plane (GTP-U) packet header completes matching (the first round of matching)) obtains the source UE N4 session, and the corresponding forwarding action rule (forwarding action rule, FAR) indicates that the The message is forwarded to the 5G VN internal to enter the second round of PDR matching (matching is completed based on the destination IP in the message), and the destination UE N4 session is obtained, and the corresponding FAR indicates that the message is forwarded to the destination UE through the N3 port.
如果同组内的两个相互通信的UE不在同一个PSA UPF下，则需要通过N19接口完成数据交互。SMF在涉及到的PSA UPF上为该组创建对应的组级别的N4会话，以启用N9转发和N6转发能力。当报文经过第一次匹配转发到UPF的5G VN internal后，经过PDR规则匹配(基于目的IP或条件为匹配所有(match-all)的默认规则等)最终可能匹配到组N4会话，对应的FAR指示报文通过N6发送到DN网络侧设备或通过N19发送到目的UE所在UPF上。If two communicating UEs in the same group are not under the same PSA UPF, data exchange needs to be completed through the N19 interface. The SMF creates a corresponding group-level N4 session for the group on the involved PSA UPF to enable N9 forwarding and N6 forwarding capabilities. After the packet is first matched and forwarded to the 5G VN internal of UPF, after PDR rule matching (based on the destination IP or the default rule of matching all (match-all), etc.), it may finally be matched to the group N4 session, and the corresponding The FAR indication message is sent to the DN network side device through N6 or sent to the UPF where the destination UE is located through N19.
在5G网络存在多个5G VN Group的场景下，对于5G VN internal的报文，N4会话内的匹配、转发规则属性字段网络实例(network instance)被赋值为5G VN Group唯一标识符(可称为组标识)，如使用内部组标识(internal group ID)，用于指示该报文归属于指定的5G VN Group。例如：In the scenario where there are multiple 5G VN Groups on the 5G network, for 5G VN internal packets, the matching and forwarding rule attribute field network instance in the N4 session is assigned the unique identifier of the 5G VN Group (which can be called Group ID), such as internal group ID (internal group ID), is used to indicate that the message belongs to the specified 5G VN Group. For example:
对于目的接口被设置为5G VN internal的FAR，其网络实例也应该相应的被设置为指定的5G VN Group。For the FAR whose destination interface is set to 5G VN internal, its network instance should also be set to the specified 5G VN Group accordingly.
对于源接口被设置为5G VN group的PDR，其网络实例也应该被设置为指定的5G VN group。For the PDR whose source interface is set to 5G VN group, its network instance should also be set to the specified 5G VN group.
5)局域网与5G LAN5) LAN and 5G LAN
局域网是部署在一个局部的地理范围内(如一个学校、工厂和机关内)，由将各种计算机、外部设备和数据库等互相联接起来组成的计算机通信网。它可以通过数据通信网或专用数据电路，与远方的局域网、数据库或处理中心相连接，构成一个大范围的信息处理 ***。A local area network is a computer communication network that is deployed in a local geographic area (such as a school, factory, and institution) and consists of interconnecting various computers, external devices, and databases. It can be connected with a remote local area network, database or processing center through a data communication network or a dedicated data circuit to form a large-scale information processing system.
随着新兴企业办公模式及智能居家模式的出现，有线局域网和无线局域网(wireless local area network，WLAN)显现了其在部署复杂、灵活性、移动性和覆盖范围等方面的不足，这促使局域网技术再发展以适应未来应用对应用需求。利用5G移动网络其本身的广覆盖特点，来直接提供LAN服务，称之为5G LAN。5G LAN可以在更广泛的移动网络覆盖范围内使用，即无论用户是否在同一地域，只要加入同一5G LAN，即可实现基于LAN的数据交换和通信。利用已经广覆盖的移动网络，5G LAN服务的创建及其伸缩迁移调整均可由移动网络自动完成，不需要人工干预。此外，5G LAN可按需定制，不同5G LAN间互相安全隔离。With the emergence of emerging enterprise office models and smart home models, wired local area networks and wireless local area networks (wireless local area network, WLAN) have shown their deficiencies in deployment complexity, flexibility, mobility and coverage, which has prompted local area network technology Re-development to meet future application-to-application requirements. Using the wide coverage characteristics of the 5G mobile network itself to directly provide LAN services is called 5G LAN. 5G LAN can be used in a wider range of mobile network coverage, that is, no matter whether users are in the same region or not, as long as they join the same 5G LAN, LAN-based data exchange and communication can be realized. Utilizing the mobile network that has been widely covered, the creation of 5G LAN services and their scaling, migration and adjustment can be automatically completed by the mobile network without manual intervention. In addition, 5G LANs can be customized on demand, and different 5G LANs are securely isolated from each other.
终端通过建立传统的PDU连接解决了终端与数据网络之间的数据交换问题。5G LAN在传统PDU连接的基础上，增加了组(group)的概念，即归属于同一个5G LAN组的终端既能与组对应的数据网络完成数据交换，又能通过UPF直接同组内的其它终端完成数据交换，属于不同group的终端之间相互隔离。通过5G LAN可实现虚拟专网通信。The terminal solves the problem of data exchange between the terminal and the data network by establishing a traditional PDU connection. On the basis of traditional PDU connection, 5G LAN adds the concept of group (group), that is, terminals belonging to the same 5G LAN group can not only complete data exchange with the data network corresponding to the group, but also directly communicate with the terminals in the group through UPF. Other terminals complete data exchange, and terminals belonging to different groups are isolated from each other. Virtual private network communication can be realized through 5G LAN.
图2为同一个5G LAN组下的多个终端注册在同一个PSA UPF的用户面架构。此场景下，由于终端1和终端2归属于同一个5G LAN组，因此PSA UPF除了为终端1、终端2完成与数据网络的数据交换之外，还作为5G LAN组的本地交换(localswitch)节点完成终端1与终端2之间的数据交换。Figure 2 shows the user plane architecture where multiple terminals under the same 5G LAN group are registered in the same PSA UPF. In this scenario, since Terminal 1 and Terminal 2 belong to the same 5G LAN group, the PSA UPF not only completes the data exchange with the data network for Terminal 1 and Terminal 2, but also serves as the local switch node of the 5G LAN group Complete the data exchange between terminal 1 and terminal 2.
图3为同一个5G LAN组下的多个终端注册在多个PSA UPF的用户面架构。此场景下PSA UPF之间增加了N19接口，归属于同一个5G LAN组的终端1、终端2在进行数据交换时，将由终端1、终端2分别对应的PSA UPF通过N19通道完成终端数据的传输。Figure 3 shows the user plane architecture in which multiple terminals under the same 5G LAN group are registered in multiple PSA UPFs. In this scenario, the N19 interface is added between the PSA UPFs. When Terminal 1 and Terminal 2 belonging to the same 5G LAN group perform data exchange, the PSA UPFs corresponding to Terminal 1 and Terminal 2 will complete the transmission of terminal data through the N19 channel. .
移动网络内可同时支持多个5G LAN组，同一个组下的终端可相互通信。不同组之间终端相互隔离。The mobile network can support multiple 5G LAN groups at the same time, and terminals under the same group can communicate with each other. Terminals in different groups are isolated from each other.
如图4A所示，在目前的toB场景中需要运营商和企业共同维护5G LAN组信息。在企业增加或删除5G LAN组时，由企业技术人员(如信息技术(information technology，IT)人员)通过运营商网络入口站点(portal)调用运营商提供的接口，通运营商维护人员在UDM中增加或删除5G LAN组对应的DNN和S-NSSAI的组合的配置，其中，portal例如是AF。新增的5G LAN组中的UE(如设备1至设备4)必须先签约好对应的DNN和S-NSSAI的组合。此外，企业定义的5G LAN组的网络数据存储在DN-AAA中，SMF在建立新增的5G LAN组中UE的以太PDU会话时，需要使用二次鉴权流程从DN-AAA中获取该UE的工作参数，工作参数例如包括UE可以使用媒体访问控制(media access control，MAC)地址列表和虚拟局域网(virtual local area network，VLAN)列表等，用于以太PDU会话的建立。该方案中，SMF到DN-AAA的传输路径必须通过运营商的网管设备配置。并且，UPF与DN侧虚拟扩展局域网(virtual extensible local area network，VXLAN)隧道端点(VXLAN tunnel end point，VTEP)网关的参数必须通过运营商的网管设备配置，VTEP网络可服务于多个VLAN，如VLAN1至VLAN3。As shown in Figure 4A, in the current toB scenario, operators and enterprises need to jointly maintain 5G LAN group information. When an enterprise adds or deletes a 5G LAN group, the enterprise technicians (such as information technology (IT) personnel) call the interface provided by the operator through the operator's network portal (portal), and the operator's maintenance personnel can access the UDM in UDM. Add or delete the configuration of the combination of DNN and S-NSSAI corresponding to the 5G LAN group, where the portal is, for example, AF. UEs in the newly added 5G LAN group (such as device 1 to device 4) must first sign up for the combination of the corresponding DNN and S-NSSAI. In addition, the network data of the 5G LAN group defined by the enterprise is stored in the DN-AAA. When the SMF establishes the Ethernet PDU session of the UE in the newly added 5G LAN group, it needs to use the secondary authentication process to obtain the UE from the DN-AAA. The working parameters include, for example, the UE can use the media access control (media access control, MAC) address list and the virtual local area network (virtual local area network, VLAN) list, etc., for the establishment of the Ethernet PDU session. In this solution, the transmission path from SMF to DN-AAA must be configured through the operator's network management equipment. In addition, the parameters of the virtual extensible local area network (virtual extensible local area network, VXLAN) tunnel endpoint (VXLAN tunnel end point, VTEP) gateway (VXLAN tunnel end point, VTEP) gateway on the UPF and DN side must be configured through the network management equipment of the operator. The VTEP network can serve multiple VLANs, such as VLAN1 to VLAN3.
可见目前的toB场景中，在增加或删除5G LAN组时，需要企业通过运营商维护人员在UDM进行5G LAN组的配置变更，存在5G LAN组部署周期过长的问题。It can be seen that in the current toB scenario, when adding or deleting a 5G LAN group, the enterprise needs to change the configuration of the 5G LAN group in the UDM through the operator maintenance personnel, and there is a problem that the deployment period of the 5G LAN group is too long.
本申请实施例提供一种通信方法，用于提供5G LAN组的快速部署和管理方案，且能够避免在多个***中分别维护5G LAN组的数据，提高5G LAN组管理可靠性。该方法可由上述图1A和图1B中***架构下的UDR、NEF、NRF和AF实现。此外，该方法还可 涉及由SMF和UPF执行的动作。如图4B所示，基于本申请实施例，企业技术人员可通过入口站点和NEF将企业规划的5G LAN配置信息配置到运营商网络的UDR，由UDR将相关参数提供给SMF，如果需要根据5G LAN配置信息更改隧道参数，则SMF可通过UPF进行相应参数的变更。运营商网络中，UDM中保存原有用于UE上网所需的签约数据，如鉴权参数等，5G LAN配置信息等相关数据则存储在UDR中，通过NEF对外开放，以方便企业录入规划参数。该方案中不需要企业将5G LAN相关参数配置在DN-AAA中。可选的，UDR可以采用企业独占式部署，企业与UDR一一对应，也可以将UDR部署在企业所在的园区中。The embodiment of the present application provides a communication method, which is used to provide a rapid deployment and management solution of 5G LAN groups, and can avoid separately maintaining data of 5G LAN groups in multiple systems, and improve the reliability of 5G LAN group management. This method can be realized by the UDR, NEF, NRF and AF under the system architecture in the above-mentioned Fig. 1A and Fig. 1B. Furthermore, the method may also involve actions performed by the SMF and UPF. As shown in Figure 4B, based on the embodiment of this application, enterprise technicians can configure the 5G LAN configuration information planned by the enterprise to the UDR of the operator network through the entrance site and NEF, and the UDR will provide relevant parameters to the SMF. If the LAN configuration information changes the tunnel parameters, the SMF can change the corresponding parameters through the UPF. In the operator's network, the UDM stores the original subscription data required for the UE to access the Internet, such as authentication parameters, and other relevant data such as 5G LAN configuration information is stored in the UDR, which is opened to the outside world through the NEF to facilitate the entry of planning parameters by enterprises. In this solution, enterprises do not need to configure 5G LAN related parameters in DN-AAA. Optionally, the UDR can be deployed exclusively by the enterprise, and the enterprise corresponds to the UDR one by one, or the UDR can be deployed in the campus where the enterprise is located.
如图5所示，该方法可包括以下步骤：As shown in Figure 5, the method may include the following steps:
S101：AF向NEF发送5G LAN参数配置请求(本申请中可简称为第四请求)。相应的，NEF接收5G LAN参数配置请求。S101: The AF sends a 5G LAN parameter configuration request (which may be referred to as the fourth request for short in this application) to the NEF. Correspondingly, the NEF receives the 5G LAN parameter configuration request.
该5G LAN参数配置请求用于请求存储5G LAN配置信息，其中，5G LAN参数配置请求携带5G LAN配置信息、S-NSSAI和DNN。或者说，5G LAN参数配置请求可指示5G LAN配置信息、S-NSSAI和DNN之间的对应关系。5G LAN配置信息可由企业进行规划，在规划5G LAN配置信息后，企业侧可通过第四请求，请求运营商网络存储5G LAN配置信息。The 5G LAN parameter configuration request is used to request storage of 5G LAN configuration information, wherein the 5G LAN parameter configuration request carries 5G LAN configuration information, S-NSSAI and DNN. In other words, the 5G LAN parameter configuration request can indicate the correspondence between 5G LAN configuration information, S-NSSAI and DNN. The 5G LAN configuration information can be planned by the enterprise. After planning the 5G LAN configuration information, the enterprise side can request the operator network to store the 5G LAN configuration information through the fourth request.
其中，5G LAN配置信息可用于新增、删除或管理5G LAN组。具体的，5G LAN配置信息可包括以下信息中的至少一项：Among them, 5G LAN configuration information can be used to add, delete or manage 5G LAN groups. Specifically, the 5G LAN configuration information may include at least one of the following information:
与该S-NSSAI和该DNN对应的5G LAN组的信息(如5G LAN组的名称或标识)，因此可用于指示与每个S-NSSAI和DNN的组合对应的5G LAN组。Information about the 5G LAN group corresponding to the S-NSSAI and the DNN (such as the name or identity of the 5G LAN group) can thus be used to indicate the 5G LAN group corresponding to each combination of S-NSSAI and DNN.
或者，与该S-NSSAI和该DNN对应的每个5G LAN组分别对应的企业侧隧道参数，如隧道的IP地址和VXLAN网络标识(VXLAN network identifier，VNI)，因此该配置信息可用于配置每个5G LAN组的企业侧隧道参数。Or, the enterprise-side tunnel parameters corresponding to each 5G LAN group corresponding to the S-NSSAI and the DNN, such as the IP address of the tunnel and the VXLAN network identifier (VXLAN network identifier, VNI), so this configuration information can be used to configure each Enterprise-side tunnel parameters of a 5G LAN group.
或者，UE(或UE的标识)、该S-NSSAI和该DNN对应的5G LAN组的信息，因此配置信息可指示UE与5G LAN组之间的对应关系。Alternatively, information about the 5G LAN group corresponding to the UE (or the identifier of the UE), the S-NSSAI and the DNN, so the configuration information can indicate the correspondence between the UE and the 5G LAN group.
或者，UE(或UE的标识)、该S-NSSAI和该DNN对应的工作参数，这里的工作参数可包括MAC地址列表或VLAN列表等用于配置以外PDU会话的参数，因此配置信息可指示UE适用的工作参数。Alternatively, the UE (or UE's identity), the S-NSSAI and the corresponding working parameters of the DNN, the working parameters here may include MAC address list or VLAN list and other parameters used to configure PDU sessions outside, so the configuration information may indicate UE Applicable operating parameters.
在S101之前，企业可规划5G虚拟网，也就是规划5G LAN组，得到5G LAN配置参数。可选的，企业可通过运营商提供的接口如应用程序接口(application programming interface，API)向AF发送5G LAN配置信息。其中，企业可一并将5G LAN配置信息、S-NSSAI和DNN通过API发送至AF。Before S101, enterprises can plan 5G virtual networks, that is, plan 5G LAN groups, and obtain 5G LAN configuration parameters. Optionally, the enterprise can send 5G LAN configuration information to the AF through an interface provided by the operator, such as an application programming interface (application programming interface, API). Among them, enterprises can send 5G LAN configuration information, S-NSSAI and DNN to AF through API.
S102：NEF向NRF发送UDR查询请求(本申请中可称为第三请求)，用于请求UDR的信息。该UDR查询请求中可包括该S-NSSAI和该DNN。NRF中可存储该S-NSSAI和该DNN与UDR之间的对应关系。该UDR可用于存储该S-NSSAI和该DNN对应的5G LAN配置信息。S102: The NEF sends a UDR query request (which may be referred to as a third request in this application) to the NRF to request information about the UDR. The UDR query request may include the S-NSSAI and the DNN. The NRF can store the correspondence between the S-NSSAI and the DNN and UDR. The UDR can be used to store the 5G LAN configuration information corresponding to the S-NSSAI and the DNN.
其中，该UDR用于存储该5G LAN配置信息。该UDR可以与该S-NSSAI和该DNN对应。Wherein, the UDR is used to store the 5G LAN configuration information. The UDR may correspond to the S-NSSAI and the DNN.
可选的，在NEF接收到5G LAN参数配置请求后，还可根据该5G LAN参数配置请求中携带的S-NSSAI和该DNN查询该S-NSSAI和该DNN对应的5G LAN组标识(以下简 称为组标识)，如果能够查询到该S-NSSAI和该DNN对应的组标识，则表示该组标识对应的5G LAN组此前已创建(或已存在)，此时UDR查询请求中可携带该组标识。如果无法查询到该S-NSSAI和该DNN对应的组标识，则执行S102，NEF通过S-NSSAI和该DNN向NRF请求UDR的UDR查询请求，实现UDR寻址。相应的，NRF接收UDR查询请求。UDR查询请求中包括S-NSSAI和DNN。Optionally, after the NEF receives the 5G LAN parameter configuration request, it can also query the 5G LAN group identity corresponding to the S-NSSAI and the DNN according to the S-NSSAI and the DNN carried in the 5G LAN parameter configuration request (hereinafter referred to as is the group identifier), if the group identifier corresponding to the S-NSSAI and the DNN can be queried, it means that the 5G LAN group corresponding to the group identifier has been created (or already exists), and this group can be carried in the UDR query request logo. If the group identifier corresponding to the S-NSSAI and the DNN cannot be found, execute S102, and the NEF requests a UDR query request of the UDR from the NRF through the S-NSSAI and the DNN to implement UDR addressing. Correspondingly, the NRF receives the UDR query request. The UDR query request includes S-NSSAI and DNN.
S103：NRF确定与该UDR查询请求中携带的S-NSSAI和该DNN对应的UDR信息。S103: The NRF determines UDR information corresponding to the S-NSSAI carried in the UDR query request and the DNN.
可选的，NRF可根据本地存储的UDR、S-NSSAI和DNN之间的对应关系确定该S-NSSAI和该DNN对应的UDR信息。Optionally, the NRF may determine the UDR information corresponding to the S-NSSAI and the DNN according to the locally stored correspondence between the UDR, the S-NSSAI and the DNN.
此外，如果UDR查询请求中还可携带组标识，则NRF可根据该组标识查询对应的UDR信息。可选的，NRF可根据本地存储的UDR和组标识之间的对应关系确定该组标识对应的UDR信息。In addition, if the UDR query request can also carry a group identifier, the NRF can query the corresponding UDR information according to the group identifier. Optionally, the NRF may determine the UDR information corresponding to the group identifier according to the locally stored correspondence between the UDR and the group identifier.
S104：NRF向NEF发送该UDR的信息。可选的，UDR的信息例如可以是UDR的标识或用于指示UDR的地址等。相应的，NEF接收该UDR的信息。S104: The NRF sends the UDR information to the NEF. Optionally, the information of the UDR may be, for example, an identifier of the UDR or an address used to indicate the UDR. Correspondingly, the NEF receives the information of the UDR.
S105：NEF根据该UDR的信息向UDR发送第一消息，第一消息中包括5G LAN配置信息、该S-NSSAI和该DNN。S105: The NEF sends a first message to the UDR according to the information of the UDR, where the first message includes 5G LAN configuration information, the S-NSSAI and the DNN.
相应的，UDR接收第一消息，并存储5G LAN配置信息、该S-NSSAI和该DNN之间的对应关系。该对应关系可用于UDR根据该S-NSSAI和该DNN查询对应的5G LAN配置信息。Correspondingly, the UDR receives the first message, and stores the 5G LAN configuration information, the correspondence between the S-NSSAI and the DNN. This correspondence can be used for the UDR to query the corresponding 5G LAN configuration information according to the S-NSSAI and the DNN.
可见在图5所示流程中，不再需要企业通过运营商维护人员在UDM中对5G LAN配置信息进行维护，只需要企业通过AF和NEF将5G LAN配置信息存储在UDR中。在部署新的5G LAN组时，只需要将S-NSSAI、DNN和5G LAN组的5G LAN配置信息的对应关系配置在UDR中，运营商网元在需要时可以直接根据S-NSSAI和DNN对UDR进行寻址，并从UDR中获取5G LAN配置信息即可实现5G LAN组的部署，因此实现了5G LAN组的快速部署。It can be seen that in the process shown in Figure 5, the enterprise no longer needs to maintain the 5G LAN configuration information in the UDM through the operator maintenance personnel, and only needs the enterprise to store the 5G LAN configuration information in the UDR through the AF and NEF. When deploying a new 5G LAN group, it is only necessary to configure the corresponding relationship between S-NSSAI, DNN, and 5G LAN configuration information of the 5G LAN group in the UDR. The UDR performs addressing and obtains the 5G LAN configuration information from the UDR to realize the deployment of the 5G LAN group, thus realizing the rapid deployment of the 5G LAN group.
并且，该方案不需要SMF通过二次鉴权过程从DN-AAA服务器获取5G LAN配置信息，也就不需要在DN-AAA服务器中维护5G LAN配置信息，因此避免分别在两个***中对5G LAN配置信息进行维护导致可能存在数据不一致的问题，可提高5G LAN配置信息管理的可靠性。In addition, this solution does not require SMF to obtain 5G LAN configuration information from the DN-AAA server through the secondary authentication process, and does not need to maintain 5G LAN configuration information in the DN-AAA server, so avoiding the need for separate 5G LAN configuration information in the two systems. Maintenance of LAN configuration information may cause data inconsistency, which can improve the reliability of 5G LAN configuration information management.
在S103的一种可能的实现方式中，NRF可根据来自于UDR的第二消息获得UDR、S-NSSAI和DNN之间的对应关系，其中，第二消息可用于指示UDR、S-NSSAI和DNN之间的对应关系。例如，第二消息中携带该S-NSSAI和该DNN，当NRF发现该S-NSSAI和该DNN来自于该UDR，则可获知UDR、S-NSSAI和DNN之间的对应关系。具体的，第二消息可用于请求注册UDR与该S-NSSAI和该DNN之间的对应关系，或者说，该第二消息可用于请求NRF存储UDR、该S-NSSAI和该DNN之间的对应关系。例如，在UDR配置过程中，可将该S-NSSAI和该DNN设置为UDR的寻址方式，也就是说，其他网元可通过该S-NSSAI和该DNN查询到该UDR。In a possible implementation of S103, the NRF can obtain the correspondence between UDR, S-NSSAI and DNN according to the second message from the UDR, where the second message can be used to indicate the UDR, S-NSSAI and DNN Correspondence between. For example, the second message carries the S-NSSAI and the DNN, and when the NRF finds that the S-NSSAI and the DNN come from the UDR, it can know the correspondence between the UDR, the S-NSSAI and the DNN. Specifically, the second message may be used to request registration of the correspondence between the UDR and the S-NSSAI and the DNN, or in other words, the second message may be used to request the NRF to store the correspondence between the UDR, the S-NSSAI and the DNN relation. For example, during the UDR configuration process, the S-NSSAI and the DNN can be set as the addressing mode of the UDR, that is, other network elements can query the UDR through the S-NSSAI and the DNN.
举例来说，在S103之前，可选的可以执行如图6中的S201所示步骤，或执行图6中的S201和S202所示步骤。应理解，图6所示的S101、S102、S103、S104和S105所示步骤可参见对于图5的说明，这里不再展开。For example, before S103, the steps shown in S201 in FIG. 6 may optionally be performed, or the steps shown in S201 and S202 in FIG. 6 may be performed.

For example, the UDR registers the S-NSSAI and DNN corresponding to the UE according to the identification number segment of the UE. At this time, the second message may also include the identifier of the UE, such as a generic public subscription identifier (GPSI) or a user permanent identifier (subscription permanent identifier, SUPI), or carry a GPSI number segment or a SUPI number segment.

以上流程中通过企业和运营商侧行为对本申请实施例提供的方法进行了介绍。下面从UE角度，对UE上线和下线过程涉及的5G LAN配置流程进行描述。其中，UE号段与UE所属5G LAN组的S-NSSAI和DNN之间的对应关系存储在UE中，例如存储在UE的SIM卡中。应理解，同一个5G LAN组中的UE对应的S-NSSAI和DNN的组合相同。In the above process, the method provided by the embodiment of the present application is introduced through the behavior of the enterprise and the operator. The following describes the 5G LAN configuration process involved in the UE online and offline process from the perspective of UE. Wherein, the corresponding relationship between the UE number segment and the S-NSSAI and DNN of the 5G LAN group to which the UE belongs is stored in the UE, for example, in the SIM card of the UE. It should be understood that the combinations of S-NSSAI and DNN corresponding to UEs in the same 5G LAN group are the same.
本申请实施例提供的通信方法还可应用于UE上线过程。在UE上线过程中，SMF可根据来自于UE的会话建立请求建立UE的以太PDU会话。其中，该会话的建立过程中，SMF可根据UE在会话建立请求中携带的S-NSSAI和DNN，向NRF发送第五请求，以请求与该S-NSSAI和该DNN对应的UDR的信息。SMF还可根据该S-NSSAI和该DNN，向UDR发送第一请求，用于请求与该S-NSSAI和该DNN对应的5G LAN配置信息。SMF还可根据从UDR获得的5G LAN配置信息确定5G LAN组对应的企业侧隧道参数，其中，该5G LAN组对应于该S-NSSAI和该DNN。UPF可配置该5G LAN组对应的企业侧隧道参数，使得该UE的以太PDU会话根据该隧道参数进行数据传输。The communication method provided in the embodiment of the present application may also be applied to a UE online process. During the UE online process, the SMF can establish the UE's Ethernet PDU session according to the session establishment request from the UE. Wherein, during the establishment of the session, the SMF may send a fifth request to the NRF according to the S-NSSAI and DNN carried by the UE in the session establishment request, so as to request information about the UDR corresponding to the S-NSSAI and the DNN. The SMF may also send a first request to the UDR according to the S-NSSAI and the DNN, for requesting 5G LAN configuration information corresponding to the S-NSSAI and the DNN. The SMF can also determine the enterprise-side tunnel parameters corresponding to the 5G LAN group according to the 5G LAN configuration information obtained from the UDR, where the 5G LAN group corresponds to the S-NSSAI and the DNN. UPF can configure the enterprise-side tunnel parameters corresponding to the 5G LAN group, so that the UE's Ethernet PDU session can perform data transmission according to the tunnel parameters.
