具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明实施例中一种无线局域网通信方法的流程示意图，本方法流程可以由网络终端实施，所述网络终端可以为具有无线局域网热点建立功能的终端或运行在终端的软件程序，所述终端可以包括无线路由器、手机、笔记本电脑、车载电脑等。如图所示所述方法至少包括：
步骤S101，获取接入所述无线局域网接入点的接入终端标识。
具体的，接入终端标识是识别接入终端的一种标识，可以是接入终端的名称、号码、身份码等，例如IMEI(International Mobile Equipment Identity，国际移动设备身份码)、电话号码、自定义终端名称等等，这里不作具体限定。需要说明的是，每个接入终端的接入终端标识是在该无线局域网中唯一的。这里，接入终端可以是具备无线接入功能和通信功能的移动终端，例如手机。
在本实施例中，由于接入终端与无线局域网接入点保持的连接关系，网络终端可以获取接入所有接入无线局域网的接入终端标识。例如，设定接入终端标识为接入终端的内部号码，设第一接入终端的内部号码为6001，第二接入终端的内部号码为6002，则网络终端可以获取到第一接入终端标识6001以及第二接入终端标识6002。
步骤S102，向所述接入终端标识分配IP地址，建立IP映射表，所述IP映射表包含所述接入终端标识以及所述接入终端标识对应的IP地址。
具体的，IP映射表是反映接入终端标识与IP地址之间对应关系的映射表。
在本实施例中，网络终端在获取到接入无线局域网接入点的所有接入终端标识后，可以向每个接入终端标识分配一个IP地址，也即向每个接入终端分配一个IP地址，根据接入终端标识与分配的IP地址之间的对应关系，网络终端可以建立IP映射表，IP映射表中包含了网络终端获取到的各接入终端标识以及各接入终端标识对应的IP地址。也就是说，通过IP映射表，建立了接入终端标识与其对应的IP地址的对应关系，通过IP地址可以查找到对应的接入终端标识，通过接入终端标识也可以查找到对应的IP地址。
例如，终端获取到第一接入终端标识6001以及第二接入终端标识6002，则可以向6001分配一个对应的IP地址183.33.33.1，向6002分配一个对应的IP地址183.33.33.2，从而可以建立包含6001和6002及其对应的IP地址的IP映射表。
步骤S103，将所述IP映射表发送给接入所述无线局域网接入点的接入终端，以使所述接入终端接收到用户输入的针对目标接入终端标识的通信指令时，根据所述IP映射表获取目标接入终端标识对应的目标IP地址，与所述目标IP地址对应的目标接入终端建立通信连接。
具体的，网络终端建立了IP映射表之后，就可以将该IP映射表发送给接入无线局域网接入点的所有接入终端。当接入终端接收到用户输入的针对目标接入终端标识的通信指令时，可以查询接收到的IP映射表中目标接入终端标识对应的目标IP地址，通过目标IP地址，向目标接入终端发送连接请求，在目标接入终端接受请求之后，与目标接入终端建立通信连接。
需要说明的是，目标接入终端标识可以是接入无线局域网接入点的任一接入终端标识，即无线局域网接入点的接入终端之间可以互相通信。针对目标接入终端标识的通信指令可以是用户对目标接入终端标识进行的双击、长按、按下拨打按键等操作，这里不作具体限定。
例如，网络终端将IP映射表发送给接入无线局域网接入点的所有接入终端后，接入终端接收到针对6001的通信指令，此时接入终端可以查询到IP映射表中6001所对应的IP地址为183.33.33.1，则接入终端可以发送基于183.33.33.1IP地址的Socket连接请求，目标接入终端接受请求之后可以返回ACK确认字符，接入终端接收到确认字符后就可以与目标IP地址对应的目标接入终端建立通信连接，即进行通话。
可选的，该方法还可以包括：
当检测到新增接入终端接入所述无线局域网接入点时，更新所述IP映射表。
具体的，网络终端检测到有新增接入终端接入无线局域网接入点时，可以获取新增接入终端的接入终端标识，并向新增接入终端的接入终端标识分配IP地址，此时无线局域网中的接入终端增加了，则网络终端将新增接入终端的接入终端标识和对应的IP地址增加到原有的IP映射表中形成更新后的IP映射表。
例如，网络终端检测到新增接入终端接入无线局域网接入点时，获取到新增接入终端的接入终端标识为6003，网络终端给新增的6003分配一个对应的IP地址183.33.33.3，将6003以及6003对应的IP地址183.33.33.3加入原来仅包含6001和6002及其对应的IP地址的IP映射表中，完成更新IP映射表的操作。
将更新后的所述IP映射表发送给所述无线局域网接入点的接入终端。
具体的，网络终端将IP映射表更新完毕后，将新的IP映射表发送给无线局域网接入点的接入终端，以使接入终端可以与新增的接入终端进行通信。
可选的，该方法还可以包括：
接收所述接入终端发送的接入信息，所述接入信息包括所述接入终端的IP地址以及接入终端标识。
具体的，接入信息可以是网络终端定时或者接收到用户指令时向各个接入终端发出接入信息的获取请求后，接入终端发送给网络终端的；也可以是接入终端定时或者接收到用户指令时向网络终端发送的；还可以是接入终端自动检测到用户修改了接入信息中的内容后触发的向网络终端发送接入信息的操作，这里不作具体限定。
检测在所述IP映射表中所述接入终端的IP地址对应的接入终端标识与接收到的所述接入信息中的接入终端标识是否一致。
具体的，网络终端在接收到接入终端发送的接入信息后，可以在IP映射表中查找接入信息中的接入终端的IP地址所对应的接入终端标识，对比IP映射表中对应的接入终端标识与接入信息中的接入终端标识，判断两者是否是一致的。
若不一致，则将所述IP映射表中所述接入终端的IP地址对应的接入终端标识更新为接收到的所述接入信息中的接入终端标识。
具体的，若网络终端检测到IP映射表中对应的接入终端标识与接入信息中的接入终端标识不一致，则将IP映射表中对应的接入终端标识替换为接入信息中的接入终端标识。
例如，用户在接入终端中将原本为“6001”的接入终端标识更改为了“6004”，则网络终端接收到的接入信息即为“6004-183.33.33.1”，网络终端接收到接入信息后，通过IP映射表查询到183.33.33.1对应的接入终端标识为6001，对比后可以确定IP地址为183.33.33.1的接入终端在IP映射表中的接入终端标识6001与接入信息中的入终端标识6004不一致，则将IP映射表中的183.33.33.1对应的接入终端标识从6001替换为6004。
将更新后的所述IP映射表发送给所述无线局域网接入点的接入终端。
具体的，网络终端将IP映射表更新完毕后，将新的IP映射表发送给无线局域网接入点的接入终端，以使接入终端可以与更改了接入终端标识的接入终端进行通信。

步骤S204，根据所述目标IP地址，与所述目标IP地址对应的目标接入终端建立通信连接。
具体的，接入终端通过查询到的目标IP地址，可以向目标IP地址发送连接请求，目标IP地址对应的目标接入终端若接受该请求，则接入终端可以与目标加入终端建立通信连接，则无线局域网接入点内的两个接入中就可以实现相互通信。
在本实施例中，目标接入终端在接入终端发送连接请求之前，可以对网络进行监听，当监听到接入终端发送的连接请求后，可以根据不同情况进行不同的反馈。只有当接入终端接收到目标接入终端的确认反馈后，才可以与目标接入终端建立通信连接并进行通信。
例如，若目标接入终端当前处于通信空闲状态，则检测用户是否触发应答、接听或者通话等接受指令，若触发接受指令，则目标接入终端则可以向接入终端发送确认消息，进而建立通信连接；若检测到用户长时间未触发接受指令或者出发了拒绝接听的拒绝指令，则目标接入终端可以不对连接请求进行反馈，或者反馈拒绝消息；若目标接入终端当前处于通信状态，则目标接入终端也可以不对连接请求进行反馈，或者反馈繁忙消息。
可选的，步骤S204可以包括：
根据所述目标IP地址，向所述目标IP地址对应的目标接入终端发送连接请求。

本发明实施例通过获取接入无线局域网接入点的接入终端标识，向所述接入终端标识分配IP地址，建立IP映射表，所述IP映射表包含所述接入终端标识以及所述接入终端标识对应的IP地址，将所述IP映射表发送给接入所述无线局域网接入点的接入终端，以使所述接入终端接收到用户输入的针对目标接入终端标识的通信指令时，根据所述IP映射表获取目标接入终端标识对应的目标IP地址，与所述目标IP地址对应的目标接入终端建立通信连接，可以使接入同一无线局域网接入点的所有移动终端之间实现通信，从而提高了内部通信的便捷性以及通信效率。另外，本发明可选实施例还增加了网络终端与接入终端对IP映射表的双向更新，提高了通信的准确性。
图5是本发明实施例中一种接入终端的组成结构示意图。如图所示所述终端包括：
接收模块510，设置为接收网络终端发送的IP映射表，所述IP映射表包含接入终端标识以及接入终端标识对应的IP地址。
具体的，IP映射表是反映接入终端标识与IP地址之间对应关系的映射表，包含了接入无线局域网接入点的所有接入终端标识以及对应的IP地址。接收模块510接收到网络终端发送的IP映射表后，就可以获取到网络终端给接入终端自身分配的IP地址，同时也可以获取到其他与接入终端接入同一无线局域网接入点的其他接入终端标识对应的IP地址。例如IP映射表中可以包括“6001-183.33.33.1”以及“6002-183.33.33.2”，分别代表第一接入终端标识以及对应的IP地址和第二接入终端以及对应的IP地址。
指令模块520，设置为接收用户输入的针对目标接入终端标识的通信指令。
具体的，目标接入终端标识可以是接入无线局域网接入点的任一接入终端标识，通信指令可以是用户针对目标接入终端标识进行的双击、长按、按下拨打按键灯操作，这里不作具体限定。例如，用户在接入终端中输入为6001的目标终端标识，并且按下拨号键，则指令模块520则接收到了针对目标接入终端标识为6001的通信指令。
查找模块530，设置为根据所述IP映射表，查找所述目标接入终端标识对应的目标IP地址。
具体的，查找模块530通过IP映射表可以查找到与目标终端标识对应的目标IP地址。例如，用户输入的目标接入终端标识为6001，此时查找模块530可以查询到IP映射表中6001所对应的IP地址为183.33.33.1。
通信模块540，设置为根据所述目标IP地址，与所述目标IP地址对应的目标接入终端建立通信连接。
具体的，通过查询到的目标IP地址，通信模块540可以向目标IP地址发送连接请求，目标IP地址对应的目标接入终端若接受该请求，则通信模块540可以与目标加入终端建立通信连接，则无线局域网接入点内的两个接入中就可以实现相互通信。
在本实施例中，目标接入终端在接入终端发送连接请求之前，可以对网络进行监听，当监听到通信模块540发送的连接请求后，可以根据不同情况进行不同的反馈。只有当通信模块540接收到目标接入终端的确认反馈后，才可以与目标接入终端建立通信连接并进行通信。
例如，若目标接入终端当前处于通信空闲状态，则检测用户是否触发应答、接听或者通话等接受指令，若触发接受指令，则目标接入终端则可以向通信模块540发送确认消息，进而建立通信连接；若检测到用户长时间未触发接受指令或者出发了拒绝接听的拒绝指令，则目标接入终端可以不对连接请求进行反馈，或者反馈拒绝消息；若目标接入终端当前处于通信状态，则目标接入终端也可以不对连接请求进行反馈，或者反馈繁忙消息。
所述通信模块540包括：请求单元541和通信单元542，如图6所示，其中：
请求单元541，设置为根据所述目标IP地址，向所述目标IP地址对应的目标接入终端发送连接请求。
具体的，请求单元541可以向目标接入终端发送基于IP地址的Socket连接请求，其中，Socket连接请求中可以包括接入终端的接入终端标识以及IP地址。目标接入终端接收到连接请求后，则可以获取到连接请求的来源，进而可以在目标接入终端中显示给用户。进一步地，如果目标接入终端用户还相应的存储了接入终端标识的用户姓名，则目标接入终端还可以进一步显示接入终端对应的用户姓名。
通信单元542，设置为当接收到所述目标接入终端发送的确认字符时，与所述目标IP地址对应的目标接入终端建立通信连接。
具体的，确认字符可以是目标接入终端接收到用户输入的接收通信指令之后发送的ACK确认字符，代表目标接入终端已经接收到连接请求，并且同意该连接请求。
在可选实施例中，当通信单元542接收到确认字符后，就可以与目标IP地址对应的目标接入终端建立基于IP的通信连接，通信单元542与目标接入终端之间可以双向传输语音或视频信息，双方对接收到的语音或视频信息进行解码即可获取信息内容。
发送模块550，设置为将接入信息发送给所述网络终端，所述接入信息包括本端的IP地址以及接入终端标识，以使所述网络终端在检测到所述IP映射表中所述接入终端的IP地址对应的接入终端标识与所述接入信息中的接入终端标识不一致时，将所述IP映射表中所述接入终端的IP地址对应的接入终端标识更新为所述接入信息中的接入终端标识。
具体的，接入信息可以是网络终端定时或者接收到用户指令时向各个接入终端发出接入信息的获取请求后，发送模块550发送给网络终端的；也可以是发送模块550定时或者接收到用户指令时向网络终端发送的；还可以是发送模块550自动检测到用户修改了接入信息中的内容后触发的向网络终端发送接入信息的操作，这里不作具体限定。
在可选实施例中，网络终端在接收到发送模块550发送的接入信息后，可以在IP映射表中查找接入信息中的接入终端的IP地址所对应的接入终端标识，对比IP映射表中对应的接入终端标识与接入信息中的接入终端标识，判断两者是否是一致的。若网络终端检测到IP映射表中对应的接入终端标识与接入信息中的接入终端标识不一致，则将IP映射表中对应的接入终端标识替换为接入信息中的接入终端标识。
例如，用户在接入终端中将原本为“6001”的接入终端标识更改为了“6004”，则网络终端接收到的接入信息即为“6004-183.33.33.1”，网络终端接收到接入信息后，通过IP映射表查询到183.33.33.1对应的接入终端标识为6001，对比后可以确定IP地址为183.33.33.1的接入终端在IP映射表中的接入终端标识6001与接入信息中的入终端标识6004不一致，则将IP映射表中的183.33.33.1对应的接入终端标识从6001替换为6004。
更新接收模块560，设置为接收所述网络终端发送的更新后的所述IP映射表。
具体的，网络终端将IP映射表更新完毕后，会将新的IP映射表发送给无线局域网接入点的更新接收模块560，更新接收模块560接收到更新后的IP映射表后，其他接入终端就可以与更改了接入终端标识的接入终端进行通信。
本发明实施例通过获取接入无线局域网接入点的接入终端标识，向所述接入终端标识分配IP地址，建立IP映射表，所述IP映射表包含所述接入终端标识以及所述接入终端标识对应的IP地址，将所述IP映射表发送给接入所述无线局域网接入点的接入终端，以使所述接入终端接收到用户输入的针对目标接入终端标识的通信指令时，根据所述IP映射表获取目标接入终端标识对应的目标IP地址，与所述目标IP地址对应的目标接入终端建立通信连接，可以使接入同一无线局域网接入点的所有移动终端之间实现通信，从而提高了内部通信的便捷性以及通信效率。另外，本发明可选实施例还增加了网络终端与接入终端对IP映射表的双向更新，提高了通信的准确性。
