实施例二
下面以广播灾害信息为例说明本发明实施例的技术方案。
本发明实施例是在wifi的802.11协议规定的Mac head中，2字节的Frame control的type10数据帧，subtype1000～1111Reserved(保留，未使用)这些字节中，写入灾害信息。
本发明实施例可以针对以下场景，例如用户深处灾害地区，通讯中断， 但WIFI仍然可用，此时用户可以将自己的终端设备(后文称为设备1)可以开启灾害紧急模式，在该模式下可以输入灾害信息的数据，如灾害类型、等级强度、地点、范围、受困人数，输入完毕后，终端设备会自动生成一条信息，该信息为IEEE 802.11协议的数据帧，该数据帧的保留位中含有灾害信息的数据。该信息生成后，可以通过以下方式进行广播：
方式一、使用wifi AP与wifi Client不停转换，将灾害信息迅速传播至有无线网络的地区；
方式二、利用wifi direct搜索阶段，广播与监听之间的自动切换来迅速传递信息。
设备1向周围的终端设备广播该信息，此时可以有多个终端设备(后文称为设备2、3…..10)接收到该信息，设备2接收到该信息后，同样可以通过上述的广播方式广播该信息；同样设备3至设备10也可以做类似广播信息的操作。这样该信息经过迅速的蜂窝状的对外扩散，根据wifi传输100距离计算，几分钟内可达几公里，灾害信息可以迅速到达无线信号覆盖区域，传播出去紧急情况。
下面进一步说明灾害信息的发送方法：
步骤一、假设用户将终端1的模式设置为灾害紧急模式，然后用户在终端1上编辑了有段灾害地点、强度等数据后，终端1生成一条含有灾害信息的特殊信息并广播该特殊信息。
在本实施例中，特殊信息为IEEE 802.11协议的数据帧。
根据802.11协议，802.11帧分为三个部分：帧头(Mac header)、帧实体(body)、FCS域。分为MAC header、Frame Body和FCS。MAC header由4个字段构成，分别为：Frame Control、Duration ID、Address、Seq ctl。一般情况是Address仅只有目的地址、源地址和BSSID。
Frame Control字段包括以下子字段：Protocol、Type、Subtype、To DS、From DS、More fragments、Retry、Power management、More data、Protected Frame、order，帧结构如表1：
Type(类型)与Subtype(子类型)字段用来指定使用的帧类型。为了提升可靠性，802.11MAC内置了一些管理功能。802.11无线局域网的封包分为三种：管理帧、控制帧和数据帧。在本发明实施例中，使用数据帧的保留位，在1000～1111字段加入灾害信息，信息可包括灾害类型，等级强度，地点，范围，受困人群数量等等；协议内容可在实现时协商。
Figure PCTCN2016074454-appb-000001
表1
步骤二、终端1启动灾害紧急模式后成为wifi AP。由于wifi AP具有广 播功能，因此，终端2利用广播功能，将编辑好的含有灾害信息的特殊信息广播出去。
步骤三、收到灾害信息的wifi Client(如终端2)，先保存该信息到本机RAM特定位置，也可以对收到的信息编辑后再保存到本机RAM特定位置。
终端2可以先关闭wifi Client后开启wifi AP模式，当终端2的wifi AP模式开启时候，再从特定位置提取和加载保存的特殊信息。
步骤四、终端2再次进行广播，这样经过迅速的蜂窝状的对外扩散，灾害信息可以迅速到达无线信号覆盖区域。
在上述的广播方式中，终端1启动灾害紧急模式后为wifi AP，编辑一条关于灾害地点强度等的特殊信息，广播至区域内的wifi client，而接受到信息的wifi Client，可编辑也可直接加载该信息，立即转变自己为wifi AP，继续承担广播任务。
还可以采用另一种方式广播特殊信息：
特殊信息的生成方式如上所述，再次不再赘述。
步骤A、同上述步骤一；
步骤B、终端1利用wifi direct功能广播特殊信息，终端1工作在wifi direct时，是在listen和search上依次切换的，在search时，工作在广播模式，那么可以广播步骤A编辑的特殊信息；
步骤C，接收到search信息的wifi终端3将终端3设置在wifi direct模式下，不断在listen和search上依次切换的，将特殊信息广播出去。
上述广播方式中将终端1为wifi direct模式，在广播与监听之间切换，广播出去这条信息，同时收到特殊信息的终端3也启动wifi direct模式继续传播信息。
需要说明的是，当终端设备启动灾害紧急模式后，该终端设备可以自动设置为wifi AP模式或者Wifi Direct模式。例如，终端设备的制造厂家可以优先将终端设备设置为wifi AP模式，如果wifi AP模式遇到某个原因无法设置成功，则进一步将终端设备设置为Wifi Direct模式。也可以是两种模式同时 提供给用户，用户自行选择接入哪种模式。
到某个终端设备接收到其它终端设备发送的包含灾害信息的数据帧后，如果准备进一步将该数据帧广播出去，则需要先关闭Wifi Client模式，然后可以根据***的提示先启动wifi AP模式，如果wifi AP模式遇到某个原因无法设置成功，则进一步将终端设备设置为Wifi Direct模式。也可以是两种模式同时提供给用户，用户自行选择接入哪种模式。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如***、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
工业实用性
通过本发明实施例的方案，可以将待传播信息快速的蜂窝状地对外扩散，使得受灾地区的灾害信息可以快速的到达无线信号覆盖区域，从而对受灾地区及时采取救援行动。
