具体实施方式
为了增强无线信号的强度和增大无线信号的覆盖范围，保证无线信号的正常使用，目前，处于节省成本的考虑，使用废弃的移动终端挂接在路由器下作为中继器，将接收到的无线信号发射出去，增大无线信号的覆盖范围，以扩大通信距离和无线信号覆盖范围，无线衰弱的信号得到增强。但是，路由器能够连接的设备数量有限，可以使用中继的设备的数量有限。
为解决上述问题，本发明实施例提供了一种用于移动终端的中继通信配置方法和装置。
为使上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发 明作进一步详细的说明。
参照图1，示出了本发明一个实施例的一种中继通信的配置方法实施例的步骤流程图，具体可以包括如下步骤：
步骤101，通过Wi-Fi模组的station节点连接上一级的路由器或中继节点。
在具体实现中，本发明实施例可以应用于移动终端，例如，手机、平板电脑、智能可穿戴设备(如智能手表)，等等。
这些移动终端可以安装WindowsPhone、Android(安卓)、IOS或Windows等操作系统，配置有Wi-Fi(WIreless-Fidelity，无线保真)模组，可以连接无线节点，作为中继节点，转发无线信号。
Wi-Fi模组又名串口Wi-Fi模块，属于物联网传输层，可以将串口或TTL(transistor transistor logic，晶体管-晶体管逻辑电平)信号转为符合Wi-Fi无线网络通信标准的嵌入式模块，内置无线网络协议IEEE802.11b.g.n协议栈以及TCP/IP(Transmission Control Protocol/Internet Protocol，传输控制协议/互联网络协议)协议栈。
在具体实现中，Wi-Fi模组通常有三种功能：station、softAP、P2P。
其中，station(工作站)：表示连接到无线网络中的设备，这些设备通过无线AP(WirelessAccessPoint，无线访问节点)，可以和内部其它设备或者无线网络外部通信。
softAP：表示使用应用实现AP的功能，让移动终端可以作为一个路由，让别的站点链接。
P2P(Peer-to-Peer)：又称Wi-Fi Direct，可以支持在没有AP的情况下，两个Wi-Fi设备直连并通信。
在本发明实施例中，移动终端可以作为中继节点连接上一级的设备，该设备可以为路由器，也可以为中继节点，即可以在中继节点后，挂接中继节点，形成树状的中继网络。
若移动终端为第一级的中继节点，则可以通过Wi-Fi模组的station节点连接上一级的路由器。
若移动终端为第二级或第二级以下的中继节点，则可以通过Wi-Fi模组的station节点连接上一级的中继节点。
在一种实施方式中，可以调用WifiManager中的getWifiState()方法，检测移动终端是否开启过Wi-Fi的station节点。
当检测到station节点已开启时，则可以通过调用ConnectivityManager提供的API(Application Programming Interface，应用程序编程接口)getNetworkInfo()，将ConnectivityManager.TYPE_WIFI作为参数传入，检测station节点是否连接无线节点。
如果返回的NetworkInfo对象不为null，并且isConnected()为true，确认已连接无线节点。
当检测到station节点未开启或未连接无线节点时，生成连接无线节点的提示信息，如“请打开Wi-Fi并连接路由器或中继”。
步骤102，检测作为中继节点所处的中继级别。
在具体实现中，移动终端作为中继节点接入网络之后，可以识别当前所处的中继级别。
第一级的中继节点可以称为根节点，相互连接的两级中继节点，上一级的中继节点为下一级的中继节点的父节点，相对而言，下一级的中继节点为上一级的中继节点的子节点。
在一种实施方式中，每级中继节点可以维护一个中继配置信息，在该中继配置信息中，可以记录路由路径、中继级别、登录信息(如SSID(Service Set Identifier，服务集标识)和密码)等信息。
在此实施方式中，可以将作为中继节点所处的中继级别设置为第一级。
按照预设的规范，向上一级的路由器或中继节点请求中继配置信息。
如果上一级的设备为路由器，该路由器并未设定该规范，则忽略移动终端的请求。
如果上一级的设备为中继节点，该中继节点已设定该规范，则对移动终端的请求进行响应，返回中继配置信息。
当请求成功时，从中继配置信息中提取上一级的中继节点的中继级别。
在上一级的中继节点的中继级别的基础上，计算作为中继节点所处的中继级别，以对第一级进行替换。
进一步而言，移动终端可以在上一级的中继节点的中继级别的基础上加一，则可以得到移动终端当前作为中继节点所处的中继级别。
例如，如果上一级的中继节点的中继级别为第二级，则移动终端作为中继节点的中继级别为第三级，进而将默认的第一级修改为第三级。
当请求失败时，确定作为中继节点所处的中继级别为第一级。当然，上述中继级别的检测方法只是作为示例，在实施本发明实施例时，可以根据实际情况设置其他中继级别的检测方法，例如，向上一级的路由器或中继节点请求中继等级，如果请求失败，则设置为第一级，如果请求成功，则在上一级的中继节点的中继级别的基础上，计算当前的中继级别，等等，本发明实施例对此不加以限制。另外，除了上述中继级别的检测方法外，本领域技术人员还可以根据实际需要采用其它中继级别的检测方法，本发明实施例对此也不加以限制。
步骤103，根据所述中继级别选择目标信道。
根据电磁干扰理论，非自身设备的电磁波，均为干扰源，干扰源发出电磁能，电磁能经某传播途径传输到敏感设备，敏感设备又对干扰产生某种形式的响应，并产生干扰的效果。
在本发明实施例中，移动终端中的Wi-Fi天线相隔很近、移动终端与移动中之间相距也很近，最大的干扰是来自于自身的天线或周围的天线的辐射电磁耦合，可能会导致转发数据能力较低、中继性能较差的问题。
当信号源与干扰频率相隔越近，耦合值越大，干扰则越大，因此，为降低电磁干扰，可以根据中继级别选择目标信道，以选择互不干扰的频率范围，解决了中继功能因信道设置引起的信道干扰而导致的转发数据能力较低、中继性能较差的问题。
在本发明的一个实施例中，步骤103可以包括如下子步骤：
子步骤S11，查询上一级的路由器或中继节点所处的信道，作为上行信道。
在Android系统中，WifiService是负责WiFi功能的核心服务，而其中的WifiStateMachine子系统则负责维护WiFi的各类状态信息。
该状态信息包括上一级的路由器或中继节点信道信息，因此，可以通过调用系统的mWifiStateMachine.fetchFrequencyNative()函数来获取上一级的路由器或中继节点的第一信道。
子步骤S12，确定所述上行信道的频段类型。
在实际应用中，路由器或中继节点的第一信道的工作频段有所不同，主要包括2.4G频段(2.412GHz-2.484GHz)和5G频段(5.735GHz-5.835GHz)，其中，大多数路由器或中继节点普遍使用的是运行在2.4Ghz上的无线技术，采用(第四代)802.11n标准，而运行在5Ghz高频段上的第五代Wi-Fi技术，采用802.11ac协议标准。
子步骤S13，当所述中继级别为第一级时，按照所述频段类型计算与所述上行信道互不干扰的目标信道。
若移动终端作为中继节点所处的中继级别为第一级，则移动终端连接路由器，可以直接依据路由器的上行信道的频段类型设置目标信道。
当频道类型为2.4G频段时，将上行信道偏移N个信道，作为目标信道，其中，N为正整数，且N≥5。
如图2所示，2.4G频段中的1-14信道的图谱为梯度矩阵，从频段角度，共分3个独立频段，每个独立频段的范围大致为22MHz，因为相邻的频段有交叉相等的频率值，每个独立频段内的信道均存在干扰，具体频段如下：
一区：1-5信道
二区：6-10信道
三区：11-14信道
例如，信道1和信道2共有的频率为2406-2423，此时，如果上一级的路由器或中继节点的上行信道的信道设置为1，中继节点的目标信道设置为2时，则存在频率相同区间，存在干扰。
从频段隔离的角度，共分5个隔离区间，隔离区间内的信道不存在干扰，具体区间如下：
一类：1、6、11
二类：2、7、12
三类：3、8、13
四类：4、9
五类：5、10
因此，当频道类型为2.4G频段时，可以将上行信道偏移至少5个信道，作为目标信道。
假设X为上一级的路由器或中继节点的上行信道，Y为中继节点(即移动终端)的目标信道，两者满足以下关系式：
Y≥X+5，或，Y≤X-5
其中，X、Y为正整数，当Y<1或Y>13时，Y无效，需要丢弃。
当频道类型为5G频段时，将上行信道偏移M个信道，作为目标信道，其中，M为正整数，如1、2。
如图3所示，因为5G频段不存在交叉，因此，上一级的路由器或中继节点的上行信道与当前中继节点的目标信道不为同一信道，即可以基本避免干扰。
子步骤S14，当所述中继级别为第二级或第二级以下时，检测相邻的中继节点所处的信道，作为相邻信道。
在本发明的一个实施例中，如果中继节点设置相同的服务集标识和密码，以便于进行漫游，则可以查找与移动终端的服务集标识相同的中继节点，检测所述中继节点所处的信道，作为相邻信道。
子步骤S15，按照所述频段类型计算与所述上行信道和所述相邻信道互不干扰的目标信道。
若移动终端作为中继节点所处的中继级别为第二级或第二级以下，则移动终端连接中继节点，可以依据附近中继节点的上行信道的频段类型设置目标信道。
当频道类型为2.4G频段时，将上行信道偏移N个信道，作为候选信道，其中，N为 正整数，且N≥5。
当频道类型为5G频段时，将上行信道偏移M个信道，作为候选信道，其中，M为正整数，如1、2。
当候选信道与相邻信道相同时，则可以表示当前相邻信道所属的中继节点与当前的中继节点属于同一个中继网络，可能存在干扰，因此，可以采用相邻信道所属中继节点的信号信息计算干扰系数。
对于候选信道与相邻信道不同的情况，则可以忽略该相邻信道。
在一个示例中，可以检测相邻信道所属中继节点的数量和/或信号强度，通过配置权重求和等方式，采用数量和/或所述信号强度计算干扰系数。
其中，数量和/或信号强度与干扰系数正相关，即数量越多、信号强度越强，干扰系数越大，反之，数量越少、信号强度越低，干扰系数越小。
此后，按照干扰系数从候选信道中选取目标信道，一般情况下，选择干扰系数最小的候选信道中选取目标信道。
需要说明的是，当候选信道的数量为一个时，将距离候选信道最远的、编号最小的信道或编号最大的信道设置为候选信道。
因此，从频段隔离的角度，共分5个隔离区间，隔离区间内的信道不存在干扰，具体区间如下：
一类：1、6、11
二类：2、7、12
三类：3、8、13
四类：4、9、13
五类：1、5、10
对于第四类和第五类，假设上行信道为9，5，上行信道偏移5个信道，分别得到4、14(丢弃)，0(丢弃)、10信道，则可以添加13，1信道作为候选信道。
假设Y为上一级的路由器或中继节点的上行信道，Z为中继节点(即移动终端)的目标信道，两者满足以下关系式：
Z≥Y+5，或，Z≤Y-5
其中，Y、Z为正整数，当Z<1或Z>13时，Z无效，需要丢弃。
步骤104，根据所述中继级别启动所述Wi-Fi模组的softAP节点，以在所述目标信道连接下一级的应用终端和/或中继节点。
如果移动终端的Wi-Fi模组的station节点已连接到上一级的路由器或中继节点，则可 以按照中继级别向Wi-Fi模块发送中继指令，启动softAP节点，通过softAP节点连接下一级的应用终端和/或中继节点。
其中，应用终端可以指实现自身功能的终端，例如，智能电饭煲、智能空调、智能热水器，等等。
需要说明的是，移动终端除了可以作为中继节点之外，也可以作为应用终端，实现浏览网页、游戏、播放网络视频等功能。
在本发明的一个实施例中，可以确定softAP节点的信道，该信道一般与路由器、其他中继节点不存在干扰，因此，可以在该信道上下发中继指令。
在具体实现中，不同信道对应的频率为：
Freq＝2412(信道1)  Freq＝2417(信道2)  Freq＝2422(信道3)
Freq＝2427(信道4)  Freq＝2432(信道5)  Freq＝2437(信道6)
Freq＝2442(信道7)  Freq＝2447(信道8)  Freq＝2452(信道9)
Freq＝2457(信道10) Freq＝2462(信道11) Freq＝2467(信道12)
Freq＝2472(信道13)
当中继级别为第一级时，接收用户输入的登录信息，该登录信息包括服务集标识和密码。
在此情况下，可以在UI(User Interface，用户界面)提示用户输入中继(即移动终端)的SSID和密码。
若用户在UI输入了SSID和密码，则使用该SSID和密码，否则，使用默认的SSID和密码。
当中继级别为第二级或第二级以上时，从上一级的中继节点的中继配置信息中提取登录信息，保持父节点与子节点之间登录信息的相同，在无效网络信号较差(如小于-90DB)的情况下，可以启动漫游，采用相同的登录信息自动连接相邻的其他中继节点。
若获取了登录信息，则可以根据目标信道、服务集标识和密码启动Wi-Fi模组的softAP节点，以在目标信道广播服务集标识。
在具体实现中，将freq(信道)、SSID和密码写入到hostapd.conf配置文件中，启用softAP节点服务的中继指令为：
hostapd-d hostapd.conf
即可将freq、SSID和密码生效。
中继指令发送后，中继节点(即移动终端)发出的广播帧就会携带SSID，其它终端扫描到以后就可以用SSID和密码进行连接了。
在具体实现中，中继节点(即移动终端)可以视为一个AP，它周期性地广播Beacon帧，其他station设备扫描到该Beacon帧就可以得到中继节点(即移动终端)的SSID。
当接收到一个或多个电子设备(下一级的应用终端和/或中继节点)针对SSID发送的申请请求时，向一个或多个电子设备返回应答消息challenge text。
当接收到一个或多个电子设备发送的连接请求时，验证连接请求中密码与预设的密码是否相同，若是，则接入一个或多个电子设备。
步骤105，根据所述中继级别配置中继通信参数，以支持在所述station节点与所述softAP节点之间进行通信。
在本发明实施例中，不同中继级别的中继节点，具有不同的中继通信参数，使得station节点与softAP节点之间可以进行通信，由于station节点连接上一级的无线节点，softAP节点连接下一级的应用终端和/或中继节点，使得上一级的路由器或中继节点与下一级的应用终端和/或中继节点可以进行通信，实现中继功能。
在本发明的一个实施例中，步骤105可以包括如下子步骤：
子步骤S21，开启包转发功能。
在具体实现中，可以通过echo属性值开启包转发功能，以支持在station节点与softAP节点之间转发数据包：
echo 1>/proc/sys/net/ipv4/ip_forward
包转发，是允许数据包从一个终端转发到另一个终端。
在本发明实施例中，打开包转发功能，支持数据包在station节点与softAP节点之间相互转发数据包。
子步骤S22，当所述中继级别为第一级时，设置网络地址转换功能的配置信息。
在实际应用中，可以调用通过系统地址表服务iptables发送NAT(Network Address Translation，网络地址转换功能)的配置信息至Wi-Fi模组，NAT将自动修改IP报文的源IP地址和目的IP地址，以对应用终端的IP地址进行伪装。
当然，在发送路由表和NAT之前，还可以清除在先的路由表。
Iptables、NAT配置的配置信息如下：
#remove old rules(清理在先的路由表)
iptables-F
iptables-t filter-F
iptables-t nat-F
#Bring up NAT rules
iptables-t nat-A POSTROUTING-s 192.168.49.0/24-d 0.0.0.0/0-j MASQUERADE
其中，假设中继(即移动终端)的IP段是192.168.49.0，发送Bring up NAT rules可以将192.168.49.0/24网段为源地址的数据包进行重新封包、解包处理，伪装为0.0.0.0/0的源地址。
子步骤S23，当所述中继级别为第二级或第二级以下时，从上一级的中继节点分配IP地址，并建立各级中继节点之间的路由路径。
在具体实现中，对于第二级或第二级以下的中继节点，可以动态对其分配IP地址。
在一种实施方式中，可以将总共的地址空间分割成多段或者多个子域，每个中继节点又可以将分配给自己的地址继续从中分配给子节点，而应用终端没有子节点，所以不需要分配地址。
作为中继节点的移动终端具有地址池，即地址的集合，第二级或第二级以下的中继节点的地址池容量由从其父节点决定，父节点通过如下公式计算出地址池容量：
C skip(d)＝1+C m×(L m-d-1)  R m＝1
C skip(d)＝(1+C m-R m-C m×R m Lm-d-1)/(1-R m)  R m≠1
其中，C skip(d)表示中继级别为d的父节点在分配地址时确定的偏移量，对应子节点的地址池容量，C m表示中继节点所能接收的最大子结点数，L m表示网络的最大深度(中继级别)，R m表示中继节点所能接收的最大子节点数，d表示节点深度(中继级别)。
深度d在入网时父节点深度增加1，协调器的深度规定为0，C m、L m、R m这三个参数可以有用户提供，描述网络的规模和大致形态。
计算出偏移量C skip(d)后，父节点根据入网子节点的类型确定其网络地址。
若子节点为中继节点，可以采用如下公式计算地址：
A n＝A p+C skip(d)×(n-1)+1  1≤n≤R m
其中，A p为父节点的网络地址，n为申请入网的节点是第几个子中继节点，A n为第n个入网子中继节点获得的网络地址。
在本发明实施例中，可以在各个中继节点中维护一个中继路由表，在该中继路由表中，可以在每个中继节点在入网时记录其所分配的地址，以及，该中继节点与其他中继节点之间的父子节点关系，每个中继节点在退网时删除其所分配的地址，这样，各级别的中继之间的父子节点关系、地址可以组成各级中继的路由路径。
子步骤S24，查询上一级的路由器或中继节点的IP地址。
子步骤S25，将上一级的路由器或中继节点的IP地址，设置为域名系统的网关地址。
上述子步骤S24～S25是可选步骤。在另外的例子中，上述子步骤S23为可选步骤，即，当所述中继级别为第二级或第二级以下时，执行子步骤S24～S25。
在本发明实施例中，一方面，可以调用系统中的地址表服务iptable发送基于TCP(Transmission Control Protocol，传输控制协议)的DNS(Domain Name System，域名系统)的网关地址至Wi-Fi模组；
命令格式为：
iptables-t nat-I PREROUTING-i(中继设备名)-p tcp--dport 53-j DNAT--to-destination(网关)
另一方面可以调用系统中的地址表服务iptable，发送基于UDP(Open System Interconnection，开放式系统互联)的DNS的网关地址至Wi-Fi模组。
命令格式为：
iptables-t nat-I PREROUTING-i(中继设备名)-p udp--dport 53-j DNAT--to-destination(网关)
当中继级别为第一级的中继节点时，将DNS的网关地址设置为路由器的网关地址。
当中继级别为第二级或第二级以下的中继节点时，将DNS的网关地址为设置为上一级的中继节点的IP地址。
如上，给中继设备(即移动终端)添加TCP和UDP的DNS网关地址，在配置DNS后，输入的URL(Uniform Resource Locator，统一资源定位符)会被逐级传递，最终被DNS服务器解析，实现网络通信。
本发明实施例在移动终端配置有Wi-Fi模组，通过Wi-Fi模组的station节点上一级的路由器或中继节点，启动Wi-Fi模组的softAP节点，以连接下一级的应用终端和/或中继节点，根据当前所处的中继级别配置中继通信参数，以支持在station节点与softAP节点之间进行通信，将移动终端实现为中继节点，在中继节点中后挂中继节点，形成多级的中继网络，拓宽了网络的结构层级，增加了中继节点的数量，从而提高了连接的数量，在智能家电、手持终端等设备增多的情况，保证新增的设备可以连接中继，正常使用无线信号。
并且，目标信道自适应中继级别进行调整，信道之间互不干扰，提高了中继功能的转发数据能力、提升了中继性能。
为使本领域技术人员更好地理解本发明实施例，以下通过具体的示例来说明本发明实施例中的中继网络。
如图4所示，假设在一间房子中，具有一间客厅、一间厨房、两间卧室(包括主卧、次卧)和一个书房，其中，主卧和书房相近，次卧与厨房相近。
在本示例中，将路由器42摆放在客厅中，路由器42接入基站41，并作为无线节点，广播Wi-Fi信号。
由于客厅面积较大、墙壁阻挡，主卧、次卧、书房和厨房中Wi-Fi信号较弱，因此，可以在客厅中放置移动终端432，在主卧附近放置移动终端431，在书房附近放置移动终端4313，在次卧和厨房附近放置移动终端4321，在厨房附近放置移动终端43213，在次卧附近放置移动终端43211。

智能冰箱432121、智能微波炉432122、智能厨炉432123作为应用终端接入移动终端43112。
参照图5，示出了本发明一个实施例的另一种中继通信的配置方法实施例的步骤流程图，应用在移动终端中，该移动终端配置有Wi-Fi模组，该方法具体可以包括如下步骤：
步骤501，通过所述softAP节点接收下一级的应用终端和/或中继节点发送的数据包。
当应用终端与外部网路的目标设备(如网页服务器)进行通信时，应用终端所生成的数据包，通过中继节点逐级传输，直至发送至目标设备。
步骤502，将所述数据包从softAP节点转发至station节点。
在具体实现中，由于开启了包转发功能，因此，可以将数据包从softAP节点转发至station节点，实现中继节点内部数据包的转发。
步骤503，根据所述通信配置参数通过所述station节点将所述数据包发送至上一级的路由器或中继节点。
在实际应用中，可以按照不同中继级别的通信配置参数，对数据包进行处理，以实现中继通信。
在本发明的一个实施例中，步骤503可以包括如下子步骤：
子步骤S31，当所述数据包中具有统一资源定位符URL时，查询域名系统DNS的网关地址。
子步骤S32，通过所述station节点按照所述网关地址，将所述数据包发送至上一级的路由器或中继节点。
在本发明实施例中，在应用终端访问网页等情况下，进行URL的解析。
移动终端的DNS的网关地址为上一级的中继节点的IP地址，则可以将解析URL的数据包转发至上一级的中继节点。
而当前级别的中继节点的DNS的网关地址为上一级的中继节点的IP地址，则可以将解析URL的数据包转发至上一级的中继节点。
直至到达第一级的中继节点，其D NS的网关地址为路由器的IP地址，则可以将解析URL的数据包转发至路由器，路由器发送至外网提供域名解析的服务器，将URL映射为IP地址。
在本发明的另一个实施例中，步骤503可以包括如下子步骤：
子步骤S33，当所述中继级别为第一级时，将所述数据包中的源地址，从所述应用终端的IP地址转换为所述移动终端的IP地址。
子步骤S34，通过所述station节点将伪装来自所述移动终端的IP地址的数据包发送至上一级的路由器。
对于第一级的中继节点，可以将数据包中的源地址(即移动终端的IP地址)，如 192.168.49.0，则基于NAT的配置信息，伪装成移动终端本身的IP地址，如0.0.0.0，再转发至路由器。
在本发明的另一个实施例中，步骤503可以包括如下子步骤：
子步骤S35，当所述中继级别为第二级或第二级以下时，通过所述station节点将所述数据包发送至上一级的中继节点。
在本发明实施例中，对于第二级或第二级以下的中继节点，则可以直接将数据包转发至上一级的中继节点。
步骤504，通过所述station节点接收上一级的路由器或中继节点发送的数据包。
当外部网络的目标设备与应用终端进行通信时，目标设备生成的数据包，逐跳向中继节点(即移动终端)传输，直至发送至应用终端。
步骤505，将所述数据包从所述station节点转发至所述softAP节点。
在具体实现中，由于开启了包转发功能，因此，可以将数据包从节station点转发至softAP节点，实现中继节点内部数据包的转发。
步骤506，根据所述通信配置参数通过所述softAP节点将所述数据包发送至下一级的应用终端或中继节点。
上述图5所示的流程中，步骤501～503为数据上行传输过程，步骤504～506为数据下行传输过程。在实际应用中，可能仅进行数据上行传输，也可能仅进行数据下行传输，还可能既进行数据上行传输也进行数据下行传输。
在实际应用中，可以按照不同中继级别的通信配置参数，对数据包进行处理，以实现中继通信。
在本发明的一个实施例中，步骤506可以包括如下子步骤：
子步骤S41，当所述中继级别为第一级时，将所述数据包中的目的地址从所述移动终端的IP地址转换为所述应用终端的IP地址。
子步骤S42，当所述中继级别为第二级或第二级以下时，在所述数据包中查询源地址，获知所述应用终端的IP地址。
子步骤S43，通过各级中继节点之间的中继路由表查询从所述移动终端的IP地址路由至所述应用终端的IP地址的目标路径。
子步骤S44，在所述目标路径中查询下一级的应用终端或中继节点的IP地址。
子步骤S45，通过所述softAP节点按照下一级的应用终端或中继节点的IP地址将所述数据发送至下一级的应用终端或中继节点。
对于第一级的中继节点，可以确认数据包来源的station节点的第二IP地址，在路由 表中查找第二IP地址对应的第一IP地址，则可以将数据包转发至第一IP地址所属的softAP节点。
对于第一级的中继节点，可以将数据包中的目标地址(即移动终端本身的IP地址)，如0.0.0.0，则基于NAT的配置信息，转换为应用终端的IP地址，如192.168.49.0。对于每一级的中继节点，由于可以连接多个中继节点，即具有多条路由至应用终端的路径，因此，在下发数据包时，可以查询数据包中的目标地址，确定数据包发送的应用终端。
查询中继路由表，获知可路由至该应用终端的目标路径，从该路径中查询下一级的移动终端或中继节点的IP地址，将数据包转发至该IP地址。
如果下一级为应用终端，则通过softAP节点将数据包发送至该应用终端，应用终端进行相应的处理，例如，加载网页、播放视频等。
如果下一级为中继节点，则通过softAP节点将数据包发送至该中继节点，该中继节点可以继续进行向下进行中继通信。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。
