为使本发明的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
参见图1，本发明实施例提出了一种基于多无线连接的数据传输方法，包括：预先设置互联网协议(IP，Internet Protocol)适配层，IP适配层与传输控制协议(TCP，Transmission Control Protocol)/用户数据报协议(UDP，User Data Protocol)层之间建立第一上下行套接字(socket)连接，并分别与分组数据网关(PGW，Packet Data Gateway)和用户设备(UE，User Equipment)均支持的N个无线连接的IP层之间建立N组第二上下行socket连接。
图2为本发明实施例中增加IP适配层后的通信模型示意图。如图2所示，自身支持N个无线连接，其中，N为大于或等于1的整数。IP适配层与TCP/DUP层建立第一上下行socket连接，并分别与N个无线连接的IP层建立N组第二上下行socket连接。
其中，无线连接可以是长期演进(LTE，Long Term Evolution)、无线局域网络(WLAN，Wireless Local Area Network)等。
其中，PGW可以采用向UE发送查询消息的方式获取UE支持的无线连接；或UE自身向PGW上报自身支持的无线连接。
该方法还包括：
步骤100、在IP适配层通过建立的第一上下行socket连接接收来自TCP/DUP层的各第一TCP/UDP报文，通过建立的第二上下行socket连接将接收到的各第一TCP/UDP报文发送给不同的无线连接的IP层。
本步骤中的通过建立的第二上下行socket连接将接收到的各第一TCP/UDP报文发送给不同的无线连接的IP层包括：
预先在IP适配层中保存第一编号和无线连接之间的对应关系；
对接收到的第一TCP/UDP报文的TCP/UDP头进行解析得到第一TCP/UDP报文的第二编号；将得到的第二编号除以N得到的余数作为第一编号，在对应关系中查找其对应的无线连接，将第一TCP/UDP报文发送给查找到的无线连接的IP层。
或者，
本步骤中的通过建立的第二上下行socket连接将接收到的各第一TCP/UDP报文发送给不同的无线连接的IP层包括：
获取N个无线连接的服务质量，判断出第一TCP/UDP报文小于预先设置的第一阈值，将第一TCP/UDP报文发送给第一无线连接的IP层；判断出第一TCP/UDP报文大于或等于第(N-1)阈值，将第一TCP/UDP报文发送给第N无线连接的IP层；当N大于或等于3时，判断出第一TCP/UDP报文大于或等于第M阈值，且小于第(M+1)阈值，将第一TCP/UDP报文发送给第(M+1)无线连接；其中，M为大于或等于1且小于或等于(N-2)的整数；其中，从第一无线连接至第N无线连接，服务质量由差到好依次变化，也就是说，第一无线连接为N个无线连接中服务质量最差的无线连接，第N无线连接为N个无线连接中服务质量最好的无线连接。这样，将报文大的第一TCP/UDP报文发送给了服务质量好的无线连接。
其中，可以根据无线连接的传输速率、时延、误码率、重传次数等确定无线连接的服务质量，具体实现属于本领域技术人员的公知常识，并不用于限定本发明实施例的保护范围，这里不再赘述。
其中，无线连接的传输速率、时延、误码率、重传次数等可以由媒体访问控制(MAC，Media Access Control)层以管理帧的方式发送给IP适配层。
图3为本发明实施例中IP适配层将第一TCP/UDP报文发送给不同的无线连接的IP层的示意图。如图3所示，比如：假设N等于2，即只应用两个无线连接传输数据，假设预先设置的第一编号与无线连接之间的对应关系为：第一编号为1对应第一个无线连接，第一编号为2时对应第二个无线连接。那么，IP适配层会将第二编号为单数如1，3，5等的TCP/UDP报文发送给第一个无线连接的IP层，而将第二编号为偶数如2，4，6等的TCP/UDP报文发送给第二个无线连接的IP层。
当IP适配层通过建立的第二上下行socket连接接收到来自IP层的第二TCP/UDP报文时，本发明实施例的方法还包括：
步骤101、对来自IP层的各第二TCP/UDP报文进行缓存。
步骤102、当判断出缓存的各第二TCP/UDP报文的第二编号连续，且不存在源地址和目的地址相同的下一个第二TCP/UDP报文时，根据各第二TCP/UDP报文的第二编号按照由小到大的顺序将各第二TCP/UDP报文发送给TCP/UDP层。
本步骤中，判断出各源地址和目的地址相同的第二TCP/UDP报文不存在下一个第二TCP/UDP报文包括：
第二编号最大的第二TCP/UDP报文中指示是否存在下一个第二数据包的标识显示不存在下一个第二TCP/UDP报文。
下面通过具体实施例详细说明本发明实施例的方法。

步骤400、分别在UE和PGW中增加设置IP适配层。
步骤401、UE在IP适配层接收到来自LTE或WLAN的第一TCP/UDP层的第一TCP/UDP报文，第一实施例中，假设将第二编号为单数的第一TCP/UDP报文发送给LTE的IP层，将第二编号为偶数的第一TCP/UDP报文发送给WLAN的IP层。
步骤402、UE在LTE的IP层按照现有的协议将数据包通过LTE对应的空口发送给SGW，WLAN的IP层按照现有的协议将数据包通过WLAN对应的空口发送给AP，SGW或AP按照现有的协议将数据包发送给PGW。
步骤403、如果PGW在IP适配层接收到来自LTE和WLAN的IP层的第二TCP/UDP报文，则缓存接收到第二TCP/UDP报文；第一实施例中，假设当缓存8个第二TCP/UDP报文时，如果接收到的8个第二TCP/UDP报文的第二编号连续，且第二编号为8的第二TCP/UDP报文指示没有下一个第二TCP/UDP报文，则将接收到的8个第二TCP/UDP报文按照第二编号由小到大的顺序发送给LTE或WLAN的TCP/UDP层。

步骤500、分别在UE和PGW中增加设置IP适配层。

步骤502、PGW在LTE的IP层按照现有的协议将数据包发送给SGW，WLAN的IP层按照现有的协议将数据包发送给AP，SGW或AP按照现有的协议将数据包发送给UE。
步骤503、如果UE在IP适配层接收到来自LTE和WLAN的IP层的第二TCP/UDP报文，则缓存接收到第二TCP/UDP报文；第一实施例中，假设当缓存8个第二TCP/UDP报文时，如果接收到的8个第二TCP/UDP报文的第二编号连续，且第二编号为8的第二TCP/UDP报文指示没有下一个第一数据包，则将接收到的8个第二TCP/UDP报文按照第二编号由小到大的顺序发送给LTE或WLAN的TCP/UDP层。
