本公开要求于2022年10月14日向中华人民共和国国家知识产权局提交的申请号为202211260873.7、发明名称为“服务管理方法、系统、装置、电子设备及存储介质”的发明专利申请的全部权益，并通过引用的方式将其全部内容并入本公开中。
领域
本公开涉及通信技术领域，尤其涉及服务管理方法、系统、装置、电子设备及存储介质。
背景
车载以太网中通常包含classic AUTOSAR架构下的电子控制单元(electronic control unit，ECU)、传感器、智能传感器等设备，以及adaptive AUTOSAR架构下的高性能计算机、车载蜂窝网络通信模块等设备，这些设备通过以太网交换机连接到车载以太网。其中，车载蜂窝网络通信模块的核心可以为Linux系统核心。
车载以太网通过车载蜂窝网络通信模块连接广域网，进行车到云通信，车载蜂窝网络通信模块向车载以太网中的设备提供各种各样的服务，例如语音电话、紧急电话、OTA升级、数据传输、WIFI/蓝牙管理控制等。这些服务可能归属于车载以太网的不同虚拟局域网(virtual local areanetwork,VLAN)中。一般的，车载WIFI/蓝牙等无线设备安装于车载蜂窝网络通信模块上，由车载蜂窝网络通信模块统一管理控制。由于安全等原因，车载以太网中通常会通过VLAN技术，将这些服务划分到不同的域，如车载娱乐域、自动驾驶域等。
车载以太网的VLAN技术建立在数据链路层，以虚拟局域网标签VLAN tag机制为基础工作，因此要求归属于不同VLAN的服务使用不同的MAC地址。但是，车载蜂窝网络通信模块通常只设置一个以太网接口(物理链路)，此时车载蜂窝网络通信模块仅能提供一个MAC地址， 但这并不能满足为处于不同VLAN的服务均分配MAC地址的需求，或者说，不足以支持将车载蜂窝网络通信模块提供的大量服务部署在车载以太网不同的域中。
概述
第一方面，本公开提供了服务管理方法，应用于车载蜂窝网络通信模块，该方法包括：
构建虚拟以太网交换机与多个虚拟MAC层设备；多个虚拟MAC层设备与多个MAC地址一一对应；
将多个虚拟MAC层设备分配到车载以太网的虚拟局域网VLAN中；以及

详述
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
为了解决车载蜂窝网络通信模块提供的MAC地址较少，不能满足为不同VLAN的服务均分配MAC地址的需求的问题，本公开的某些实施例提供了服务管理方法，应用于车载蜂窝网络通信模块中，该车载蜂窝网络通信模块可位于任一车载设备中。如图2所示，该方法包 括步骤201至步骤203。
步骤201：构建虚拟以太网交换机与多个虚拟MAC层设备。
在某些实施方案中，多个虚拟MAC层设备与多个MAC地址一一对应。
在某些实施方案中，多个虚拟MAC层设备包括设备1与设备2，设备1对应MAC地址1，设备2对应MAC地址2。
在某些实施方案中，车载蜂窝网络通信模块利用其上的硬件资源和软件资源，以构建虚拟机的方式，构建虚拟以太网交换机与虚拟MAC层设备，即在逻辑和功能上虚拟了一个以太网交换机和多个MAC层设备。随后，车载蜂窝网络通信模块使用构建得到的虚拟MAC层设备对应的MAC层，替代车载蜂窝网络通信模块中的原MAC层。
也就是说，虚拟以太网交换机与多个虚拟MAC层设备均处于车载蜂窝网络通信模块中。此时，在车载以太网一侧看来，原本的车载蜂窝网络通信模块，从逻辑上分成了一个虚拟以太网交换机和多个虚拟MAC层设备。
在某些实施方案中，车载蜂窝网络通信模块使用其硬件资源与软件资源，枚举成多个网络设备，即上述虚拟以太网交换机与多个虚拟MAC层设备，并提供多条独立的数据/控制通道。
在某些实施方案中，虚拟以太网交换机与多个虚拟MAC层设备通过多个通道连接。这多个通道与多个虚拟MAC层设备之间一一对应。可以理解的是，这多个通道中每一通道都有其独立的MAC地址，即独立的MAC子层。
在某些实施方案中，虚拟以太网交换机与多个虚拟MAC层设备之间的通道为数据/控制通道。
在某些实施方案中，车载蜂窝网络通信模块在构建虚拟以太网交换机与多个虚拟MAC层设备后，获取多个MAC地址，并将这多个MAC地址一一分配给多个虚拟MAC层设备。也就是说，建立这多个MAC地址与多个虚拟MAC层设备之间的一一对应关系。
在某些实施方案中，3个虚拟MAC层设备即设备1至设备3，通 过3个通道即通道1至通道3，分别与虚拟以太网交换机连接。此时，这3个通道分别有其独立的MAC地址(或者说MAC层)。将MAC地址1至MAC地址3分别分配给设备1至设备3，则该通道1至通道3所具有的MAC地址分别为MAC地址1至MAC地址3。
在某些实施方案中，这多个MAC地址可以是车载以太网枚举出来并发送给车载蜂窝网络通信模块的。相应地，车载蜂窝网络通信模块接收(或者说获取)到这多个MAC地址。
在某些实施方案中，车载蜂窝网络通信模块通过虚拟以太网交换机获取车载以太网发送的信息，例如多个MAC地址。
在某些实施方案中，这多个MAC地址也可以是车载蜂窝网络通信模块本身枚举出来的。只是，车载蜂窝网络通信网络模块枚举MAC地址的方式与车载以太网中枚举MAC地址的方式相同，以保证两者所枚举出的MAC地址相同。在某些实施方案中，车载蜂窝网络通信网络模块枚举MAC地址，并将枚举出的MAC地址发送给车载以太网，以使得车载以太网将这些MAC地址配置给不同的VLAN。
在某些实施方案中，这多个MAC地址也可以是由其他设备枚举并同步给车载以太网与车载蜂窝网络通信模块的，以保证两者中用于分配的MAC地址的一致性。
在某些实施方案中，车载蜂窝网络通信模块通过驱动，构建虚拟以太网交换机与虚拟MAC层设备。
步骤202：将多个虚拟MAC层设备分配到车载以太网的虚拟局域网VLAN中。
在某些实施方案中，车载以太网(中的任一网络设备)发送VLAN信息给车载蜂窝网络通信模块。相应地，车载蜂窝网络通信模块接收VLAN信息，并基于接收到的VLAN信息中多个VLAN的信息，将多个虚拟MAC层设备一一分配给这多个VLAN。
在某些实施方案中，虚拟MAC层设备的数量大于车载以太网中的VLAN的数量。
在某些实施方案中，车载蜂窝网络通信模块接收到的VLAN信息 中，包括车载以太网各个网络设备所在的多个VLAN的信息。
在某些实施方案中，VLAN信息中包括车载以太网中各个网络设备所在的多个VLAN的标识，以及这多个VLAN对应的MAC地址。
此时，车载蜂窝网络通信模块基于VLAN信息，确定各个VLAN对应的MAC地址，结合分配给各个虚拟MAC层设备的MAC地址，并将与不同MAC地址对应的虚拟MAC层设备分配至相应的VLAN中。
在某些实施方案中，车载蜂窝网络模块将MAC地址中的MAC1-MAC3分别分配给了虚拟MAC层设备中的设备1至设备3。车载蜂窝网络通信模块接收到的VLAN信息中，包括MAC1-MAC3与VLAN1至VLAN3之间的对应关系。此时，车载蜂窝网络基于MAC1至MAC3与VLAN和虚拟MAC层设备之间的对应关系，将与MAC1-MAC3对应的设备1至设备3，分别分配给VLAN1至VLAN3。
在某些实施方案中，上述虚拟以太网交换机通过车载蜂窝网络通信模块的以太网接口与车载以太网连接。也就是说，车载以太网(中的任一网络设备)，通过以太网接口将VLAN信息发送给车载蜂窝网络通信模块中的虚拟以太网交换机。
可以理解的是，车载蜂窝网络通信模块是整个车载网络(包括车载蜂窝网络通信模块本身和车载以太网中各个网络设备等)的出口，为车载以太网中处于不同VLAN的各个网络设备提供服务。
上述过程中，多个MAC地址可以是车载蜂窝网络通信模块在接收到该VLAN信息之前，从车载以太网中获取或接收到的。
在某些实施方案中，车载蜂窝网络通信模块还可以从接收到的VLAN信息中获取到的这多个MAC地址。
此时，车载蜂窝网络通信模块可以如上所述，在将这多个MAC地址分配给多个虚拟MAC层设备后，再将虚拟MAC层设备分配给与其对应的MAC地址所对应的VLAN。
在某些实施方案中，车载蜂窝网络通信模块也可以在将多个虚拟MAC层设备分配给VLAN后，再基于VLAN与MAC地址之间的对应 关系，将这多个MAC地址分配给相应的VLAN。
通过上述过程，不论通过何种方式，均实现了建立MAC地址、虚拟MAC层设备与VLAN之间的对应关系的效果。这样的话，车载蜂窝网络通信模块可基于这三者之间的对应关系，为车载以太网中位于不同VLAN的网络设备提供服务。
步骤203：基于多个虚拟MAC层设备所在的VLAN，使用多个虚拟MAC层设备，通过虚拟以太网交换机为车载以太网中位于不同VLAN的各个网络设备提供服务。
在某些实施方案中，车载以太网(中的任一网络设备)发送服务调用请求给车载蜂窝网络通信模块，相应地，车载蜂窝网络通信模块接收服务调用请求。随后，车载蜂窝网络通信模块响应于服务调用请求，基于多个虚拟MAC层设备所在的VLAN，将目标VLAN中的虚拟MAC层设备，确定为目标虚拟MAC层设备。最后，车载蜂窝网络通信模块使用目标虚拟MAC层设备，通过虚拟以太网交换机为位于目标VLAN的目标网络设备提供服务。
在某些实施方案中，服务调用请求用于请求车载以太网中位于目标VLAN的目标网络设备提供服务。
在某些实施方案中，目标网络设备为车载以太网下各个网络设备中的任意一个。可以理解的是，目标VLAN即目标网络设备所在的VLAN。
在某些实施方案中，服务调用请求中包括目标VLAN的信息，例如目标VLAN的标识。此时，车载蜂窝网络通信模块接收到服务调用请求后，基于服务调用请求中的目标VLAN的标识，确定与该目标VLAN的标识对应的虚拟MAC层设备，即被分配处于该目标VLAN的标识对应的VLAN中的虚拟MAC层设备，并将该虚拟MAC层设备确定为目标虚拟MAC层设备。
在某些实施方案中，服务调用请求中包括目标网络设备的信息，例如目标网络设备的标识。此时，上述VLAN信息中还包括多个VLAN所对应的车载以太网中的网络设备的信息，例如网络设备的标识。车 载蜂窝网络通信模块接收到服务调用请求后，基于服务调用请求中的目标网络设备的标识，在其接收到的VLAN信息中进行查找，确定该目标网络设备的标识表示的网络设备所对应的VLAN为目标VLAN，并将该目标VLAN中的虚拟MAC层设备，确定为目标虚拟MAC层设备。
在某些实施方案中，服务调用请求中包括目标MAC地址，车载蜂窝网络通信模块接收到服务调用请求后，基于服务调用请求中的目标MAC地址，将该目标MAC地址对应的虚拟MAC层设备，确定为目标虚拟MAC层设备。
在某些实施方案中，车载蜂窝网络通信模块，在确定目标虚拟MAC层设备后，基于该目标虚拟MAC层设备对应的MAC地址，使用目标虚拟MAC层设备连接广域网，即与云端进行通信，以获取服务并将该服务提供给车载以太网中的目标网络设备。
在某些实施方案中，车载蜂窝网络通信模块中的虚拟以太网交换机通过以太网接口，接收车载以太网发送的服务调用请求，并基于服务调用请求确定目标MAC地址，并将该服务调用请求转发给该目标MAC地址对应的虚拟MAC层设备，进而使用该虚拟MAC层设备，基于该虚拟MAC地址对应的MAC地址从云端获取服务，并将该服务提供给目标网络设备。
需要说明的是，在上述过程中，车载蜂窝网络通信模块构建虚拟以太网交换机和与多个MAC地址一一对应的多个虚拟MAC层设备，并将虚拟MAC层设备分配给不同的VLAN，随后，车载蜂窝网络通信模块使用这与MAC地址一一对应的多个虚拟MAC层设备，通过虚拟以太网交换机为车载以太网中位于不同VLAN的网络设备提供服务，从而解决车载蜂窝网络通信模块提供的MAC地址较少，不能满足为不同VLAN的服务均分配MAC地址的需求的问题。
为了解决车载蜂窝网络通信模块提供的MAC地址较少，不能满足为不同VLAN的服务均分配MAC地址的需求的问题，本公开的某些实施例还提供了服务管理方法，应用于车载以太网(中的任一网络设 备)，如图3所示，该服务管理方法包括步骤301至步骤302。
步骤301：将车载以太网中各个网络设备分配到不同的虚拟局域网VLAN中。
在某些实施方案中，车载以太网依据车辆自身的预设规则，将车载以太网中的各个网络设备分配到不同的VLAN中，并对VLAN进行MAC地址的配置。
在某些实施方案中，预设规则是基于服务所涉及的信息的类型，和不同类型的信息对于安全等级的要求的不同，将需要这些服务的网络设备划分到不同的VLAN中。
在某些实施方案中，车载以太网中包括网络设备1-网络设备3，网络设备1所需的服务1、网络设备2所需的服务2和网络设备3所需的服务3，所涉及的信息的类型分别为敏感信息(例如车辆隐私信息)、控制信息(例如涉及OTA升级的信息)、和娱乐信息(例如音乐)。这3种信息所对应的安全等级不同，且服务1至服务3并不相同，此时，可将网络设备1至网络设备3分别划分至不同的VLAN，例如VLAN1至VLAN3中。
在某些实施方案中，上述配置给不同VLAN的MAC地址可以是车载以太网自行枚举得到的，也可以是由车载蜂窝网络通信模块枚举并同步给车载以太网的，或者是由其他设备枚举并同步给车载以太网与车载蜂窝网络通信模块的。
在某些实施方案中，车载以太网将其中的各个网络设备分配到不同的VLAN，并对VLAN进行MAC地址的配置后，发送VLAN信息给车载蜂窝网络通信模块。关于VLAN信息的介绍可参见上述内容，在此不进行赘述。
在某些实施方案中，车载以太网自行枚举得到多个MAC地址后，可在发送VLAN信息之前，将枚举出的配置给VLAN的多个MAC地址发送给车载蜂窝网络通信模块。
在某些实施方案中，上述无论哪一设备枚举出的MAC地址的数量，均与车载以太网中的VLAN的数量相同，以满足为不同的车载以 太网中的VLAN分配MAC地址的需求。
步骤302：基于各个网络设备所在VLAN，通过车载蜂窝网络通信模块中构建的虚拟以太网交换机与多个虚拟MAC层设备，为车载以太网中位于不同VLAN的各个网络设备获取服务。
在某些实施方案中，车载以太网基于各个网络设备所在VLAN，生成服务调用请求，并将该服务调用请求发送给车载蜂窝网络通信模块，以通过该车载蜂窝网络通信模块中构建的虚拟以太网交换机与多个虚拟MAC层设备，为车载以太网中位于不同VLAN的各个网络设备获取服务。
在某些实施方案中，服务调用请求用于请求为车载以太网中位于目标VLAN的目标网络设备提供服务。
在某些实施方案中，服务调用请求中包括目标VLAN的信息，例如目标VLAN的标识。此时，车载以太网(中任一网络设备)基于各个网络设备所在的VLAN，确定目标网络设备所在的VLAN，即目标VLAN，并基于该目标VLAN的信息生成服务调用请求。
在某些实施方案中，车载以太网发送给车载蜂窝网络通信模块的VLAN信息中还包括各个VLAN所对应的网络设备的信息，例如网络设备的标识时。此时，服务调用请求中包括目标网络设备的信息，车载以太网可直接基于目标网络设备的信息生成服务调用请求。
在某些实施方案中，服务调用请求中包括目标MAC地址，车载以太网(中任一网络设备)基于各个网络设备所在的VLAN，确定目标网络设备所在的VLAN对应的MAC地址，即目标MAC地址，并基于该目标MAC地址生成服务调用请求。
在某些实施方案中，服务调用请求中还包括目标网络设备所需服务的相关信息。
需要说明的是，上述目标网络设备可以是基于触发指令确定的，即车载以太网将其中任一接收到触发指令的网络设备确定为目标网络设备。随后，车载以太网基于该目标网络设备所处的VLAN，该VLAN对应的MAC地址等，从车载蜂窝网络通信模块为该目标网络设备获取 相应服务。
如图4所示，本公开某些实施例提供了服务管理系统，该服务管理系统包括车载以太网与车载蜂窝网络通信模块，车载以太网通过车载蜂窝网络通信模块的以太网接口与车载蜂窝网络通信模块中的虚拟以太网交换机连接。

在某些实施方案中，车载以太网，配置为将车载以太网中各个网络设备分配到不同的VLAN中；基于各个网络设备所在VLAN，通过车载蜂窝网络通信模块中构建的虚拟以太网交换机与多个虚拟MAC层设备，为车载以太网中位于不同VLAN的各个网络设备获取服务；多个虚拟MAC层设备与多个MAC地址一一对应。
在某些实施方案中，虚拟以太网交换机与虚拟MAC层设备之间通过多个通道，即数据/控制通道连接。
在某些实施方案中，服务管理系统的具体结构可如图5所示，车载以太网将其中的各个网络设备划分到不同的VLAN，即图示的VLAN1、VLAN2、…、VLANn中。车载以太网通过以太网线连接车载蜂窝网络通信模块的以太网接口，并通过该以太网接口与车载蜂窝网络通信模块中构建的虚拟以太网交换机连接。车载蜂窝网络通信模块中，虚拟以太网交换机通过n个数据/控制通道分别与n个虚拟MAC层设备连接。其中，每个虚拟MAC层设备对应一个MAC子层，即一个MAC地址。也就是说，这n个数据/控制通道分别具有其独立的MAC子层，即图示MAC子层1、MAC子层2、…、MAC子层n。其中，服务集合1中包括处于VLAN1的车载以太网中的网络设备所需的服务，服务集合2包括处于VLAN2的车载以太网中的网络设备所需服务， 服务集合n中包括处于VLANn的车载以太网中的网络设备所需服务。车载蜂窝网络通信模块基于网络设备(所需的服务)、VLAN、MAC子层(或者说MAC地址)之间的关系，将服务提供给车载以太网中的相应网络设备。
需要说明的是，本公开在使用单物理链路(以太网接口)的车载蜂窝网络通信模块中，通过硬件或软件模拟虚拟以太网交换机和多MAC子层的MAC层设备，使该单物理链路的车载蜂窝网络通信模块实现对多MAC地址的支持，解决该车载蜂窝网络通信模块无法提供足够的MAC地址给处于不同域的服务的问题。
