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。
在某些实施方案中，通过拨号建立多PDN(Packet Data Network，分组数据网络)网卡，实现对虚拟局域网(VLAN)的管理、网桥管理和路由配置等，从而实现了上位机通过RGMII接口多PDN拨号的需求。
下面主要从实现多路拨号的配置方法和多路拨号的实现方法两个方面对本公开实施例提供的技术方案进行说明。
首先，从实现多路拨号的配置方法进行说明，如图1所示，本公开实施例提供了多PDN拨号的配置方法，适用于通信模组，该方法包括如下步骤：
步骤101，获取上位机发送的至少两个PDN的拨号激活指令；其中，上位机配置为建立与各拨号激活指令各自对应的局域网虚拟网卡；
步骤102，建立各拨号激活指令各自对应的PDN虚拟网卡；其中，PDN虚拟网卡配置为与外部基站进行数据通信；
步骤103，为各局域网虚拟网卡分别创建各自的虚拟网桥，并为与虚拟网桥各自对应的局域网虚拟网卡分配IP地址；其中，每个虚拟网桥对应一个PDN虚拟网卡；以及
步骤104，发送各局域网虚拟网卡各自对应的IP地址至上位机。
在某些实施方案中，可以通过AT指令来实现上位机和通信模组之间的通信，在某些实施方案中，在上位机上输入AT+GTRNIDS＝1，1和 AT+GTRNIDS＝1，2，之后通过AT指令接口(AT port)发送到通信模组上，以激活实现多PDN拨号的配置过程。同时，上位机根据拨号激活指令，在上位机上建立与各拨号激活指令一一对应的局域网虚拟网卡。在某些实施方案中，如果上位机上输入上述2个指令，则在上位机上建立2个局域网虚拟网卡，且每个指令均对应一个局域网虚拟网卡，建立两个局域网虚拟网卡eth0.1和eth0.2。
在某些实施方案中，通信模组收到拨号激活指令后，在通信模组上建立PDN虚拟网卡，且建立的PDN虚拟网卡的数量和拨号激活指令的数量是相同的，每个拨号激活指令均对应一个PDN虚拟网卡，在某些实施方案中，如果上位机上输入上述2个指令，则通信模组接收到上述2个指令后，则在通信模组上建立2个PDN虚拟网卡。与外部基站数据通信就是通过PDN虚拟网卡实现的。
在某些实施方案中，通过创建网桥，开启IPv6转发功能。每个局域网虚拟网卡均对应一个虚拟网桥，在某些实施方案中，上述的建立了两个局域网虚拟网卡，则虚拟网桥的数量也是两个，且每个局域网虚拟网卡均对应一个虚拟网桥。
在创建虚拟网桥之前，需要判断上位机是否已经创建各局域网虚拟网卡，在某些实施方案中，在获取上位机发送的至少两个PDN的拨号激活指令之后，为各局域网虚拟网卡分别创建各自的虚拟网桥之前，还包括：判定与各拨号激活指令各自对应的局域网虚拟网卡已生成。如果判定上位机已成功建立与各拨号激活指令各自对应的局域网虚拟网卡的话，则为各局域网虚拟网卡分别创建各自的虚拟网桥。
在某些实施方案中，上位机可以主动报备当前是否已经建立好各局域网虚拟网卡，如果通信模组接收到上位机发送的确认指令；其中，确认指令用于指示上位机已建立与各拨号激活指令各自对应的局域网虚拟网卡，则根据确认指令确定与各拨号激活指令各自对应的局域网虚拟网卡已生成。
此外，还可以由通信模组向上位机发送查询指令，以查询上位机是否已经建立好各局域网虚拟网卡，在某些实施方案中，由通信模组向上位机发送查询指令；其中，查询指令用于向上位机请求是否已建立与各拨号激活指令各自对应的局域网虚拟网卡；获取针对查询指令的反馈信息；若反馈信息指示上位机已建立与各拨号激活指令各自对应的局域网虚拟网卡，则根据反馈信息确定与各拨号激活指令各自对应的局域网虚拟网卡已生成。
在某些实施方案中，可以采用上述任何一种方法来确定局域网虚拟网卡是否已经存在，当然也可以采用其他方法确定，在本公开实施例中并不做限定。
在分配IP地址时，启动DNSmasq进程，基于DNSmasq进程，为各局域网虚拟网卡分配各自的IP地址。
每个局域网虚拟网卡均配置了各自的IP地址，上位机收到各IP地址后，分别配置给各局域网虚拟网卡，至此完成了配置阶段的流程。此时，建立了局域网虚拟网卡、IP地址、虚拟网桥、PDN虚拟网卡之间的对应关系。在后续利用多PDN拨号实现通信时，需要用到该对应 关系。
在某些实施方案中，建立各拨号激活指令各自对应的PDN虚拟网卡；为各局域网虚拟网卡分别创建各自的虚拟网桥，并为与虚拟网桥各自对应的局域网虚拟网卡分配IP地址，实现了建立多PDN虚拟网卡、网桥管理和路由配置，完成了针对多PDN拨号时所需的配置，为实现多PDN拨号实现提供了可能。
此外，本公开实施例还提供了多PDN拨号的配置方法，适用于上位机，如图2所示，该方法主要包括如下步骤：
步骤201，向通信模组发送至少两个PDN的拨号激活指令；
步骤202，建立与各拨号激活指令各自对应的局域网虚拟网卡；其中，通信模组用于建立各拨号激活指令各自对应的PDN虚拟网卡；为各局域网虚拟网卡创建各自的虚拟网桥，并为与虚拟网桥对应的局域网虚拟网卡分配IP地址；其中，每个虚拟网桥对应一个PDN虚拟网卡；PDN虚拟网卡配置为与外部基站进行数据通信；以及
步骤203，获取通信模组发送的各局域网虚拟网卡各自对应的IP地址。
对于各步骤的理解可以参见上述实施例，这里不再展开描述。
以上为实现多PDN拨号的配置方法，下面对多PDN拨号的实现方法进行说明。
如图3所示，本公开实施例提供了PDN拨号方法，适用于通信模组，通信模组基于上述的适用于通信模组的多PDN拨号的配置方法预先配置好；该方法包括：
步骤301，获取上位机发送的至少两个分配IP地址的请求；
步骤302，从预先为上位机中各局域网虚拟网卡分配的IP地址中，分配与各请求分配各自对应的目标IP地址，并将各目标IP地址发送至上位机；以及
步骤303，对于每个目标IP地址，获取上位机利用目标IP地址对应的局域网虚拟网卡发送的待发送的数据；将目标IP地址转换为与外网通信时使用的外网IP地址；确定与目标IP地址对应的预先创建的虚拟网桥；确定与虚拟网桥对应的预先创建的PDN虚拟网卡；利用PDN虚拟网卡，根据外网IP地址，将待发送的数据发送至外部基站。
IP地址(Internet Protocol Address)是指互联网协议地址，又译为网际协议地址。在某些实施方案中，上位机可以通过DHCP(动态主机配置协议，Dynamic Host Configuration Protocol)客户端向通信模组的DHCP服务器请求分配IP地址。
为了便于理解，在某些实施方案中，如果在上述的配置阶段，为各局域网虚拟网卡配置了N个IP地址，N为正整数；则当上位机请求分配IP地址时，从配置阶段配置好的各IP地址中，分配与请求数量相同的IP地址。在某些实施方案中，上位机请求分配2个IP地址，则从预先配置好的IP地址中，分配2个目标IP地址给上位机。
其中，上位机收到目标IP地址之后，确定与该目标IP地址对应的局域网虚拟网卡，在某些实施方案中，2个目标IP地址对应的局域网虚拟网卡分别为eth0.1和eth0.2，则通过eth0.1和eth0.2发送待发送的 数据。
通信模组分配的IP地址都是192.168.开头的内网IP地址，仅仅开启IPv6转发功能和配置路由表无法实现外网和内网间通信，为了解决该问题就需要用到路由NAT(网络地址转换)技术，实现网络地址转换，以通过转换后的IP地址实现与外部基站的通信。
在某些实施方案中，实现了多PDN拨号时，对虚拟局域网管理和NAT路由管理，使得上位机通过RGMII实现多PDN拨号的需求，使得通信模组不仅支持RGMII单路拨号，也支持多路拨号，提升通信模组的应用范围和市场竞争力。
另外，如图4所示，本公开实施例还提供了PDN拨号方法，适用于上位机，上位机基于上述的适用于上位机的多PDN拨号的配置方法预先配置好；该方法包括：

步骤403，对于每个目标IP地址，利用目标IP地址对应的局域网虚拟网卡将待发送的数据发送至通信模组；
其中，通信模组配置为对于每个目标IP地址，将目标IP地址转换为与外网通信时使用的外网IP地址；确定与目标IP地址对应的预先创建的虚拟网桥；确定与虚拟网桥对应的预先创建的PDN虚拟网卡；利用PDN虚拟网卡，根据外网IP地址，将待发送的数据发送至外部基站。
对于各步骤的理解可以参见上述实施例，这里不再展开描述。
此外，如图5所示，本公开实施例还提供了多PDN拨号的配置系统500，其包括：上位机501和通信模组502；

通信模组502，配置为对于每个目标IP地址，将目标IP地址转换为与外网通信时使用的外网IP地址；确定与目标IP地址对应的预先创建的虚拟网桥；确定与虚拟网桥对应的预先创建的PDN虚拟网卡；利用PDN虚拟网卡，根据外网IP地址，将待发送的数据发送至外部基站503。
对于上述各步骤的理解可以参考上述方法实施例，这里不再展开描述。
为了便于理解本公开实施例提供的上述技术方案，下面结合图6对本公开实施例提供的技术方案作进一步说明。
如图6所示，左侧为上位机(HOST)，中间为通信模组，该通信模组为无线通信模组，在某些实施方案中，可以采用高通生产的MDM(移动设备管理器)；最右侧为外部基站。其中，上位机可以通过RGMII接口与MDM连接。多PDN拨号的实现方法主要包括如下步骤：
(1)输入AT+GTRNDIS＝1，X拨号后，通信模组建立PDN虚拟网卡rmnet_dataX，与外部基站数据通信的接口就是通过此网卡。其中，X代表数量。同时，上位机创建eth0.X。
(2)创建网桥bridgeX，开启网桥IPV6转发功能：判断eth0.X是否存在，如果存在，则建立eth0.X与网桥bridgeX之间的关联关系；然后，启动DNSmasq进程，分配IP地址给上位机HOST；
(3)上位机通过DHCP客户端向通信模组的DHCP服务器请求分配IP地址；
(4)分配IP地址后，启动路由NAT管理，模块对外分配的IP网段都是192.168打头的内网IP地址，仅仅开启转发功能和配置路由表也无法实现外网和内网间通信，为了解决该问题就需要用到NAT技术来实现网络地址转换。
(5)以转换后的IP地址发送数据。
还需要说明的是，图6的FIBO-FWA模块主要实现上述的(1)至(5)中对VLAN的管理，网桥管理和路由配置等。
在某些实施方案中，通信模组不仅支持RMGII单路拨号，还实现了多PDN拨号时对VLAN管理，网桥管理以及NAT路由的管理，实现上位机通过RGMII的多PDN拨号的需求，可以满足市场中对于RGMII多PDN拨号的需求，提升了通信模组的竞争力。
