技术领域
本申请实施例涉及移动通信技术领域，特别涉及一种局域网通信方法、装置、终端、电子设备和存储介质。
背景技术
5G局域网通信技术是一项十分重要的新通信技术，具备更快的传输速率、支持更多种无线移动通信工程，图1是第五代通信系统(5G)的总体架构示意图，根据5G通信的标准协议规定，架构中主要包括：AMF(Access Management Function，接入管理功能网元)、SMF(Session Management Function，会话管理功能网元)，UPF(User Plane Function，用户面功能网元)，UDM(Unified Data Management，统一数据管理网元)，PCF(Policy Control Function，策略控制功能网元)，AF(Application Function,应用功能网元)，NSSF(Network SliceSelection Function，网络切片选择功能网元)，AUSF(Authentication Server Function,鉴权服务器功能)，UE(User Equipment，用户设备)，RAN(Radio Access Network，无线接入网)，DN(Data Network，数据网络)，其中，用户面的连接为UE到RAN，然后到UPF，再接入DN；控制面的连接为UE到AMF，再到SMF。5G LAN(Local Area Network，局域网)，是使用5G系统来支持5G LAN类型服务的开展。5G LAN服务允许有限的一组UE在彼此之间进行通信，这个群组称之为VN(Virtual Network Group，虚拟网络群组)。

具体实施方式
由背景技术可知，在现行的5G局域网通信协议中，能够支持的接入方式只有IP类型数据会话接入和以太类型数据会话接入，而当前市场上很多5G以太终端受到自身芯片功能的限制，无法实现对5G局域网的接入，而为了满足接入5G局域网而进行芯片升级或者设备更换很耗费资源和时间成本，因此，如何为不支持5G局域网接入的设备提供高效便利的5G局域网业务部署是一个迫切的技术问题。
为了解决上述问题，本申请的实施例提供了一种局域网通信方法，方法包括以下步骤：获取第一终端的业务请求，业务请求包括第二终端的以太业务请求信息；其中，第一终端为支持5G局域网IP业务的终端，第二终端为第一终端连接的至少一个以太终端；根据业务请求，获取响应业务请求的以太报文的数据转发规则；将数据转发规则发送给以太报文的传输路径上的各节点；供各节点对以太报文进行IP封装和转发，直至发送到第一终端，供第一终端将解除封装后的以太报文发送给第二终端。
本申请实施例提供的局域网通信方法，获取第一终端业务请求中包含的5G局域网以太业务请求信息，通过将以太终端下挂在支持5G局域网IP类型业务的第一终端下，利用连接的第一终端实现以太设备的5G局域网接入和业务请求的发送；通过将根据第一终端业务请求中的以太业务请求信息确定的数据转发规则下发给各节点，供各节点按照数据转发规则对以太报文进行封装和转发，直至第一终端将解除封装后的以太报文发送给以太终端，使原本无法接入5G局域网的以太终端实现了5G局域网的业务部署和交互，避免了5G业务部署需要进行大规模芯片升级或者设备更换带来的巨大时间和资源成本，极大的加快了5G业务部署的进度。
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例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，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例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
下面将对结合具体的实施例的对本申请记载的局域网通信方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
本申请实施例的第一方面提供一种局域网通信方法，图2为本申请实施例中的一种通信架构的示意图，以太设备1、以太设备2连接支持5G局域网IP类型接入的用户设备1，以太设备3、以太设备4连接支持5G局域网IP类型接入的用户设备2，用户设备1、用户设备2再分别通过与无线接入网元1和无线接入网元2的连接用户面功能网元1和用户面功能网元2，用户设备1和无线接入网元1再与接入管理网元连接，会话管理网元与策略控制网元、统一数据管理网元、接入管理网元以及用户面功能网元1和2分别连接，策略控制网元再与应用功能网元连接，用户面管理网元1和2分别与数据网络1和2进行连接，其中，不同网元间的传输通道Nn是现行5G通信协议所规定的。图3为本申请一实施例提供的局域网通信方法的流程图，在一些实施例中，局域网通信方法应用于5G局域网中负责业务处理和数据处理规则控制的网元设备，第一终端可以是支持5G局域网业务的终端，例如手机、 电脑等电子设备，第二终端可以是普通的L2层终端设备或者工业化终端等设备，局域网通信方法具体包括以下步骤：
步骤301，获取第一终端的业务请求。
具体地说，5G核心网中的SMF(会话管理网元)通过AMF(接入管理网元)，获取第一终端的业务请求，业务请求包括第二终端的以太业务请求信息；其中，第一终端为支持5G局域网IP业务的终端，第二终端为第一终端连接的至少一个以太终端。
在一个例子中，作为第二终端的以太终端与作为第一终端的电脑相连接，在以太终端出现业务需求时，以太终端向电脑发送包含有业务信息的以太业务请求，电脑在接收到以太终端的以太业务请求后，对以太终端的业务请求信息进行IP封装，使得以太业务请求能够通过IP类型接入的电脑的报文在5G局域网进行传输和处理，然后电脑根据封装后的以太业务请求，向5G局域网中的AMF发起IP PDU Session Establishment Request消息(IP类型的PDU会话建立请求消息)，AMF接收来自电脑发出的包含以太业务请求的业务请求，并将获取到的业务请求发送给进行会话管理的SMF，使SMF获取到第一终端的业务请求。
步骤302，根据业务请求，获取响应业务请求的以太报文的数据转发规则。
具体地说，SMF在获取到来自第一终端的业务请求后，根据业务请求，获取响应业务请求的以太报文的数据转发规则。
在一个例子中，SMF在接收到来自AMF针对第一终端的业务请求发起的会话创建请求消息后，根据协议规定的业务处理规则对会话创建请求对应的第一终端的业务请求进行分析确定出业务请求的类型为以太业务请求，进而根据以太业务请求中包含的以太业务信息，确定出响应以太业务请求的以太报文的数据转发规则。其中，AMF向SMF发送的会话创建请求消息是AMF接收到第一终端的业务请求后，先根据对业务请求中包含的业务信息的检测和识别，确定出业务请求对应的业务类型，再根据本地配置或者UDM(统一数据管理网元)上的签约数据，获取到第一终端所属的VN群组信息，最终选择适当的SMF为第一终端的本次业务请求对应的会话进行服务后，根据现行的通信协议向选定的SMF发送的Nsmf_PDU Session_CreateSMContext Request会话创建消息。
SMF接收AMF的会话创建请求，在判定会话请求对应新建的PDU会话后，SMF与UDM进行交互，获取发起新建会话业务请求的第一终端对应的会话签约数据，其中，这些数据可以包括Ethernet over IP 5G LAN会话(以太IP的5G局域网会话)，SMF在获取到签约数据后，向AMF返回会话建立的响应。然后SMF检测是否已经完成PCF(策略控制功能网元)的配置，在配置完成后，与PCF进行交互，获取PCC控制策略(策略控制与计费)。其中，PCC控制策略可以包括AMBR(聚合最大比特率)、5QI(数据转发标识)、ARP(分配和保留优先权)等信息，然后SMF根据第一终端的IP地址以及5G局域网业务能力，在5G局域网中选取UPF(用户面功能网元)进行对新建的会话提供服务支持，并分配好第一终端IP地址对应的计费规则和控制策略等。SMF在选取好支持新建会话的UPF后，向选取的UPF发送N4Session Establisment Request(N4会话建立请求)，并在会话建立请求中携带Ethernet over IP 5G LAN指示，UPF在接收到SMF的会话建立请求后，根据SMF的指示，完成Ethernet over IP 5G LAN组内用户接入，并向SMF回复会话建立的响应消息。
另外，当业务请求对应的报文数据需要基于N6或N19进行转发时，SMF向UPF发送N4组级会话建立请求，并且携带Ethernet over IP 5G LAN指示和组级转发规则，UPF会根据 接收到的指示和转发规则，完成N4组级会话接入，并向SMF反馈组级会话建立的响应消息。
SMF接收到会话建立的响应消息后，向AMF发送Namf_Communication_N1N2 Message Transfer消息，将SMF获取到的第一终端的IP地址、隧道信息、针对第一终端的控制策略等信息通过AMF发送给RAN(无线接入网元)和第一终端(用户设备)，供第一终端和RAN直接建立数据传输的N3隧道，SMF然后从AMF处获取新建的N3隧道的信息，并将N3隧道的信息发送给UPF，供UPF更新自身存储的隧道信息，在接收到UPF反馈的会话更新成功的响应后，SMF向AMF反馈Nsmf_PDUSession_UpdateSMContext Response响应消息，SMF根据为业务请求新建会话的传输隧道、业务类型和处理方法，生成业务请求对应的数据转发规则。
在另一个例子中，SMF根据第一终端的业务请求获取待传输的以太报文和数据转发规则时，数据转发规则根据第一终端对应的配置数据生成。通过根据第一终端的配置信息为特定的业务生成对应的数据转发规则，保证以太终端能够利用第一终端准确的获取到目标以太报文。
在另一个例子中，第一终端对应的配置数据，包括以下任一：本地配置信息、统一数据管理中的签约数据、应用功能指示信息。SMF可以直接在本地获取第一终端对应的配置信息，或者在UDM中读取第一终端对应的签约信息，或者直接根据应用功能指示确定第一终端的配置数据。通过将数据转发规则设置为多种生成方式生成，尽可能保证能够成功为第一终端的以太业务生成对应的数据转发规则，最大限度提升数据转发规则生成的成功率，进而保证以太终端在5G局域网中业务处理的成功概率。
另外，SMF根据确定以太报文的数据转发规则时，可以通过根据各节点的性能择优选取传输节点，从而形成以太报文的最优转发路径，保证业务处理的效率和稳定性。
步骤303，将数据转发规则发送给以太报文的传输路径上的各节点。
具体地说，SMF根据第一终端的业务请求，生成响应业务请求的以太报文的数据转发规则后，SMF将数据转发规则发送给以太报文的传输路径上的各节点，供各节点对以太报文进行IP封装和转发，直至发送到第一终端，供第一终端将解除封装后的以太报文发送给第二终端。
在一个例子中，SMF将生成的数据转发规则通过N4口下发到UPF，供UPF在接收到包含以太业务响应信息的报文时，根据接收到数据转发规则对待传输的以太报文进行IP封装和转发，直到封装后的以太报文发送到第一终端，供第一终端在接收到封装的以太报文后，将IP封装剥除，并将解除封装以太报文发送给下挂的以太设备。
另外，当SMF是根据应用功能指示确定第一终端的配置数据时，在SMF向AMF发送Nsmf_PDUSession_UpdateSMContext Response响应消息后，应用功能指示网元向NEF(网络能力重组、搜集、分析)网元发送消息，将第一终端的业务更新为Ethernet over IP 5G LAN业务，NEF反馈更新成功后，通知SMF用户业务类型为Ethernet over IP 5G LAN，SMF对用户业务类型进行更新，重新生成Ethernet over IP 5G LAN数据转发规则，并将更新后的数据转发规则下发给各节点，供各节点对以太业务请求对应的以太报文进行处理方式的更新，从而实现Ethernet over IP 5G LAN业务的部署。
在另一个例子中，以太报文传输路径上的各节点包括：以太报文的存储节点和以太报文的转发节点；方法还包括：向存储节点发送报文生成指令，报文生成指令用于指示存储节点生成响应业务请求的以太报文，并对以太报文进行IP封装和转发。SMF通过根据以太业务 请求确定出业务请求对应的报文的存储节点后，向存储节点下发报文生成指令和数据转发规则，使得存储节点在接收到SMF的报文生成指令后，将待传输的报文转换为以太报文，并在以太报文外封装上IP隧道，转发到以太报文传输路径上的下一转发节点。
存储节点包括：DN侧设备、同一UPF下的另一终端、不同UPF下的另一终端。
当存储节点为DN侧设备时，以太报文传输流程如下：第一终端下挂的第二终端通过UPF访问DN侧设备获取报文，报文格式为Ethernet over IP，以太报文的目的MAC地址是DN侧的装置。第一终端接收下挂的第二终端(以太终端)的以太业务请求，并对以太业务请求信息进行封装，在Ethernet over IP数据外封装一层N3 GTPU(分组报文封装)隧道，通过N3隧道将封装后的数据传输到UPF节点，UPF节点在接收到数据后，剥除GTPU隧道，判断出用户信息为Ethernet over IP 5G LAN用户，然后再剥掉IP隧道，按照Ethernet 5G LAN进行N6-based转发；DN侧装置触发目的MAC为第一终端下挂的第二终端的以太业务，UPF按照Ethernet 5G LAN N6-based接收进行处理，根据Ethernet over IP 5G LAN指示，在Ethernet数据(以太报文)外封装IP隧道后进行N3 GTPU处理，并将封装后的以太报文传输到第一终端，供第一终端解除以太报文的IP封装，将以太报文传输给下挂的第二终端。
当存储节点为同一UPF下的另一终端时，以太报文传输流程如下：第一终端1下挂的第二终端1通过UPF访问同样与UPF相连接的第一终端2下挂的第二终端2，报文格式为Ethernet over IP，以太报文的目的MAC地址是第二终端2，UPF节点在接收到来自第一终端1的业务请求后，剥除GTPU隧道，判断出用户信息为Ethernet over IP 5G LAN用户，然后再剥掉IP隧道，按照Ethernet 5G LAN进行local switch(本地转发)处理，在以太报文外封装IP隧道后，再进行N3 GTPU隧道处理，供UPF后续发送承载于GTPU隧道的Ethernet over IP用户数据(以太报文)给第一终端2，供第一终端2解除以太报文的IP封装，将以太报文传输给下挂的第二终端2，从第一终端2下挂的第二终端2将第二终端1业务请求对应的以太报文传输给第二终端1时，采取镜像的方式进行回传，在此就不再赘述。
当存储节点为不同一UPF下的另一终端时，以太报文传输流程如下：第一终端1下挂的第二终端1通过UPF1访问接入在UPF2下的第一终端2下挂的第二终端2，对应第一终端1的N3隧道内数据格式为Ethernet over IP，以太报文的目的MAC地址是第二终端2，UPF1剥掉N3 GTPU隧道后根据用户信息判断为Ethernet over IP 5G LAN用户，剥掉业务请求的IP隧道，按照Ethernet 5G LAN进行N19-based处理，封装N19隧道发送到UPF2，UPF2剥掉N19 GTPU隧道后按照Ethernet 5G LAN N19-based接收转发处理，在以太报文外封装IP隧道后进行N3 GTPU处理，供后续UPF2发送承载于GTPU隧道的Ethernet over IP用户数据(以太报文)给第一终端2，供第一终端2解除以太报文的IP封装，将以太报文传输给下挂的第二终端2，从第一终端2下挂的第二终端2将第二终端1业务请求对应的以太报文传输给第二终端1时，采取镜像的方式进行回传，在此就不再赘述。
SMF根据第一终端的以太业务请求，在5G局域网中生成响应以太业务请求对应的以太报文的数据转发规则，并将数据转发规则下发到以太报文传输路径的各节点，使得各节点完成在5G局域网中的Ethernet over IP 5G LAN业务部署的流程示意图如图4所示，具体的实现过程已经在上面进行了论述，在此就不再一一赘述。
本申请实施例的另一方面提供了一种局域网通信方法，图5为本申请一实施例提供的局 域网通信方法的流程图，具体包括以下步骤：
步骤501，获取待传输的报文。
具体地说，5G局域网中的数据处理节点在接到业务指示后，根据接收到的业务指示，获取待传输的报文。其中，数据处理节点包括响应以太业务请求的以太报文的存储节点和转发节点。
在一个例子中，数据处理节点为以太报文的转发节点UPF，UPF在获取待传输的报文前，获取数据转发规则，对报文中的以太报文进行IP封装，包括：根据数据转发规则对报文中的以太报文进行IP封装。即UPF先获取SMF下发的数据转发规则，在接收到待传输的报文后，根据数据转发规则，对待传输报文中是否含有以太业务响应信息进行检测，若检测到以太业务响应信息，则后续对报文进行封装和转发时，先按照预先获取的数据转发规则对报文中的以太报文进行IP封装。通过各数据处理节点根据预先获取的数据转发规则对以太报文进行封装和转发，实现在各节点的Ethernet over IP 5G LAN业务部署，使得以太报文传输路径上的各数据处理节点能够对以太业务进行检测识别和响应的报文封装转发，保证以太终端能够获取到需要的以太报文。
步骤502，根据报文中的以太业务响应信息，对报文中的以太报文进行封装。
具体地说，UPF在检测到待传输报文中存在以太业务响应信息后，根据预先获取的数据转发规则，对获取到的报文进行解封装，将以太报文外封装的IP类型隧道剥除，并根据以太报文的数据传输路径，确定以太报文下一步需要经过的传输隧道，根据隧道信息为以太报文重新封装上相应的IP隧道。
步骤503，将封装后的以太报文发送给目标节点。
具体地说，数据处理节点在根据以太业务信息对待传输的以太报文进行封装后，将封装后的报文数据发送给目标节点，其中，目标节点可以根据以太报文的数据传输路径确定，目标节点包括但不限于是接入5G局域网的第一终端或者其他数据处理节点。
在一个例子中，数据处理节点是UPF，目标节点是接入5G网络的第一终端，则UPF在Ethernet数据(以太报文)外封装IP隧道并进行N3GTPU处理后，通过N3隧道将以太报文传输到第一终端，供第一终端解除以太报文的IP封装，并将解除封装后的以太报文发送给以太终端。
本申请实施例的另一方面提供了一种局域网通信方法，可以应用在支持5G局域网的移动终端中，包括但不限于电脑、手机等电子设备，图6是本申请一实施例中的局域网通信方法的流程图，具体包括以下步骤：
步骤601，接收以太业务请求，对业务请求进行IP封装。
具体地说，支持5G局域网业务的第一终端与以太终端相连接，第一终端接收来自以太终端的业务请求，对业务请求进行IP封装，使得以太终端的业务请求能够进入5G局域网中。其中，第一终端连接的以太终端至少是1个。
步骤602，发送封装后的业务请求，接收业务请求对应的应答报文。
具体地说，第一终端接收到的下挂以太终端的以太业务请求进行封装后，将封装后的以太业务请求发送到5G核心网中进行处理，然后接收来自5G核心网响应以太业务请求的应答报文。
步骤603，解除应答报文的IP封装，将应答报文中的以太报文发送给以太终端。
具体地说，第一终端在接收到响应以太业务请求的应答报文后，解除应答报文的IP封装，将应答报文中的以太报文发送以太终端，供下挂的以太终端获取到需要的以太报文，实现在以太终端在5G局域网中的业务处理。
