本发明的较佳实施方式
为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图及具体 实施例对本发明进行详细描述。
实施例一
图 1是本发明实施例的一种数据传输方法的流程图， 该方法可以应用于 一数据接收终端， 实现与数据发送终端的通信， 该数据接收终端和数据发送 终端可以为同一***中的两终端设备， 也可以为不同***中的两终端设备。 具体实现方法如下：
步骤 S101 : 接收数据发送终端发送的近场通信标签；
在该步骤中 ,数据发送终端选择待发送文件和启用本实施例方法的应用， 然后被靠近数据接收终端达到 NFC通信距离内时 （ 10cm以内） ， 数据发送 终端的近场通信单元将近场通信标签推送（Push )到数据接收单元， 使得数 据接收单元接收到该近场通信标签， 其中近场通信标签中携带以近场数据交 换格式（NDEF, NFC Data Exchange Fomat )写入的传输信息。 其中， 传输 信息可以是数据传输终端的蓝牙设备硬件地址， 也可以是数据传输终端的 WIFI信息， 包括数据发送终端连接的无线接入点 （AP, Access Point ) 的服 务集标识 （SSID, Service Set Identifier ) , 身份认证密钥和数据发送终端的 IP地址。 近场通信标签还携带以近场通信数据交换格式写入的数据信息和应 用标识信息， 数据信息包括数据的文件名、 文件后缀名和文件大小， 应用标 识信息标识根据近场通信数据交换格式解析近场通信标签。
步骤 S102: 解析近场通信标签， 得到传输信息；
在该步骤中，数据接收终端的近场通信单元解析接收到的近场通信标签， 得到传输信息。 当传输数据为数据发送终端的蓝牙设备硬件地址时， 数据接 收终端的近场通信单元解析得到该蓝牙设备硬件地址。 当传输信息为 WIFI 信息时， 数据接收终端的近场通信单元除解析得到数据发送终端连接的 AP 的 SSID, 身份认证密钥和数据发送终端的 IP地址外， 还获得自身连接 AP 的 SSID, 并判断数据发送终端和数据接收终端是否连接同一 AP。
步骤 S103: 根据所述传输信息与数据发送终端建立连接；
在该步骤中， 数据接收终端的连接单元利用数据发送终端的蓝牙设备硬 件地址快速建立蓝牙连接。 当与数据发送终端连接同一 AP时， 数据接收终 端的连接单元利用数据发送终端的 IP地址直接与数据发送终端建立一条端 口 （Socket )连接。 当与数据发送终端连接不同 AP时， 在断开与原有 AP的 连接后，使用数据发送终端连接的 AP的 SSID和身份认证与新 AP建立连接， 连接。 步骤 S104: 通过建立的连接接收数据发送终端发送的数据。 本实施例通过设备间釆用近场通信方式， 即在物理空间上的近距离 ( 10cm内）靠近方式实现认证，有效避免网络空间的传统认证方式的身份欺 骗问题， 确保数据传输的安全性。 而且， 通过设备间的近距离靠近取代传统 的设备上繁瑣的点选按操作， 使得用户能简单快捷地与欲连接设备自动连接 实施数据传输， 达到能耗最小化的要求。 同时， 本发明通过蓝牙、 WIFI等技 术进行数据传输， 从而保持了高传输速率的特点， 移动设备间数据交换的效 率较高。
本发明实施例中， 所述近场通信标签还可以携带以近场通信数据交换格 式写入的数据信息， 所述数据信息包括数据的文件名、 文件后缀名和文件大 小， 所述数据接收终端根据所述数据信息通过建立的连接接收所述数据发送 终端发送的数据。
实施例二
图 2是本发明实施例的基于 NFC的蓝牙数据传输方法的流程图，该方法 可以应用于同一***中的通信设备之间， 也可以应用于不同***中的通信设 备之间， 所述通信设备釆用 Android操作***， 并具有 NFC单元和蓝牙设备 并能被 Android操作***正常识别并运行。 具体实现方法如下：
步骤 S201 : 通信发送方通过通信设备 A选择待发送的文件， 在文件管 理器中的 "分享" 菜单中选择使用本方法的应用。 此时， 发送方的 NFC单元 及蓝牙设备可处于开启或关闭状态， 若处于关闭状态， 本方法的应用将自动 开启其 NFC单元及蓝牙设备。
步骤 S202: 通信发送方将通信设备 A靠近通信接收方的通信设备 B到 NFC的通信范围内。 此时， 通信接收方通信设备 B的 NFC单元需处于开启 状态。
步骤 S203: 通信设备 A查询自身的蓝牙设备硬件地址后， NFC单元将 文件信息、 自身的蓝牙硬件地址信息以及应用标识信息根据 NDEF格式写入 NFC标签， 并用 PUSH方式推送到通信接收方的通信设备 B。 其中， 应用标 识信息表明接收方接收到的 NFC标签应由 NFC单元使用本方法的应用进行 解析。 文件信息包括文件名、 文件后缀名和文件大小。 步骤 S204: 通信设备 B的 NFC单元接收到 NFC标签后利用 Android系 统自动启动解析模块， 该模块根据 NDEF格式从 NFC标签中解析出通信发 送方的蓝牙硬件地址信息和文件信息。 此时， 若接收方的蓝牙单元未开启， 则由本方法的应用自动开启。
步骤 S205: 通信设备 B的 NFC单元通过 Android***直接利用通信发 送方的蓝牙硬件地址，在通信设备 A和通信设备 B的蓝牙设备间快速建立蓝 牙连接。
步骤 S206: 通信发送方利用已建立的蓝牙连接传送选定文件。发送过程 中， 如发现蓝牙连接状态有任何变化， 则由通信设备 A和通信设备 B 的 Android***通知通信发送方和接收方蓝牙连接状态变化情况。
步骤 S207: 文件传输完毕， 断开通信设备 A和通信设备 B之间的蓝牙 连接， 提示通信发送方和接收方文件传输完毕。
本实施例通过使用 NFC技术，使得连接建立时间大大缩短，节能低耗且 通信的安全性和确定性得到保证。 此外， 本实施例操作简单快捷， 除用户第 一次点选文件操作外， 不加入其他的点选请求等操作， 极大的增强了用户的 使用感受， 融入到 Android***的 "分享"菜单中， 并且仅使用推送的方式， 不加入权限鉴别及跃迁等请求流程便于用户快速掌握该方法应用的使用。 本 实施例使用蓝牙进行通信又使得数据传输速率较快， 在保证了安全性的基础 上使得传输速率也有所保障。 本实施例的应用最大程度的融入 android *** 且兼容已有的蓝牙硬件， 不需要对已有的硬件进行任何修改。
实施例三

步骤 S301 : 通信发送方通过通信设备 S选择待发送的文件， 在文件管理 器中的 "分享" 菜单中选择使用本方法的应用。 此时， 若发送方的 NFC单元 及 WIFI设备可处于开启或关闭状态， 若处于关闭状态， 本方法的应用将自 动开启其 NFC单元及 WIFI设备。 步骤 S302: 发送方将通信设备 S靠近接收方的通信设备 R, 在 NFC通 信距离内时， 通信设备 S将自身 WIFI信息、 文件信息和应用标识信息， 用 NFC的 NDEF Push方式推送到通信设备 R。 同时，通信设备 S建立一个特定 端口的 Socket***。 其中，应用标识信息指明了该步骤中的 NDEF推送的 信息是应该被通信设备 S使用本方法的应用所解析。 WIFI信息包括通信设备 S所连接的 AP的 SSID、身份认证密钥和通信设备 S的 IP地址。文件信息包 括文件名、 文件后缀名和文件大小。
步骤 S303: 通信设备 R的 NFC单元收到 NDEF Push后， 通过 Android ***自动启动解析模块， 该模块从 NDEF信息中解析出通信设备 S的 WIFI 信息和文件信息， 同时获得通信设备 R自身所连接的 AP的 SSID,根据通信 设备 S的 WIFI信息检查本机 R是否接入某无线 AP, 或者在已接入某 AP情 况下判断是否与通信设备 S接入同一 AP。 此时， 需获得 R 自身所连接 AP 的 SSID。
步骤 S304: 判断通信设备 R与通信设备 S是否连接同一 AP;
步骤 S305: 若通信设备 R与通信设备 S连接同一无线 AP, 则通信设备
R直接用 WIFI信息中通信设备 S的 IP地址向通信设备 S建立一条 Socket 连接；
步骤 S306: 若与通信设备 S连接的不是同一 AP, 则先断开与原有 AP 的连接并保存原有连接信息， 随后使用得到的 WIFI信息中通信设备 S连接 的 AP的 SSID和密钥尝试连接该 AP, 并在连接成功后使用通信设备 S的 IP 地址向通信设备 S建立一条 Socket连接。 其中， 建立 Socket连接时， 使用的 端口号即是步骤 S302中 Socket***使用的端口号。
步骤 S307:通信设备 S接受通信设备 R的 Socket连接请求并建立连接； 步骤 S308: 通信设备 S通过建立的 Socket连接向通信设备 R发送选定 文 件 。 若 发 现 WIFI 连 接 状 态 变 化 （ 即 监 听 到 WIFI— STATE— CHAGED— ACTION广播后） ， 暂停文件传输， 等待 Android ***的 WIFI管理机制恢复该连接后继续传输。
步骤 S309: 文件传输完毕，断开通信设备 S和通信设备 R之间的 Socket 连接， 提示通信发送方和接收方文件传输完毕。 本实施例釆用 NFC物理空间内的身份确认，避免了传统近距离网络空间 内点对点文件传输时的身份伪造问题， 具有较高安全性。 通过不加入多次确 认和鉴权模块， 整个过程中用户只需进行一次点选操作和一次设备靠近的动 作， 无任何需要用户输入的操作， 极大简化了用户的操作。 融入到 Android 设备的 "分享" 菜单中， 并且仅使用推送文件的方式， 不加入拉取方式和多 种权限鉴别和跃迁请求流程， 能够使用户快速理解并掌握本方法的用法。 使 用 NFC进行辅助信息的推送， 借助 NFC技术的快速建立连接特点， 便捷的 传输少量辅助信息， 使用 WIFI进行文件的传输， WIFI技术通信距离通常在 100米左右， 且连接稳定， 速度一般可达 2 ~ 7MB/S, 因此与传统的近距离通 信方式如蓝牙等显著增大了通信距离、 连接稳定性和数据传输速率。 此外， WIFI连接已经提供多种身份认证方式，因此能够确保文件在传输过程中的安 全。
