为了使本发明的目的、 技术方案和优点更加清楚， 下面结合附图和 具体实施例对本发明进行详细描述。  The present invention will be described in detail below with reference to the drawings and specific embodiments.
实施例一、  Embodiment 1
图 1为本发明实施例一提供的主要方法流程图， 如图 1所示， 该方 法主要包括以下步骤：  FIG. 1 is a flowchart of a main method according to Embodiment 1 of the present invention. As shown in FIG. 1, the method mainly includes the following steps:
步骤 101 : 第一移动设备和第二移动设备在 NFC有效距离内时， 进 行 NFC配对， 并在 NFC配对过程中第一移动设备向第二移动设备发送 WIFI连接参数和文件发现列表。  Step 101: The first mobile device and the second mobile device perform NFC pairing when the NFC is within the effective distance, and the first mobile device sends the WIFI connection parameter and the file discovery list to the second mobile device during the NFC pairing process.
NFC是一种短距离高频无线通信技术， 允许电子设备之间进行非接 触式点对点数据传输， 可以用于对无线网络进行快速、 主动设置， 在本 发明中采用 NFC实现移动设备间的配对， 对后续的 WIFI连接进行主动 设置， 即交换 WIFI连接参数。  NFC is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices, which can be used for fast and active setting of wireless networks. In the present invention, NFC is used to implement pairing between mobile devices. The subsequent WIFI connection is actively set, that is, the WIFI connection parameters are exchanged.
通常， NFC的有效距离为 10厘米， 在 10厘米之内， 无需用户输入 任何配对码即可自动完成 NFC配对。 配对时， 可以由第二移动设备向第一移动设备发送 NFC配对请求。 第一移动设备接收到该 NFC配对请求后，通过配对确认响应向第二移动 设备发送 WIFI连接参数。 Normally, the effective distance of the NFC is 10 cm. Within 10 cm, the NFC pairing can be done automatically without the user entering any pairing code. When paired, an NFC pairing request can be sent by the second mobile device to the first mobile device. After receiving the NFC pairing request, the first mobile device sends a WIFI connection parameter to the second mobile device by using a pairing confirmation response.
其中， WIFI连接参数至少包括： WIFI网络标识（ WIFI SSID )和第 一移动设备的 IP地址信息， 第一移动设备的 IP地址信息可以采用网段 内的 IP基址， 还可以进一步包括： 信道信息、 心跳检测间隔、 连接密钥 等， 具体将在后续实施例中详细描述。  The WIFI connection parameter includes at least: a WIFI network identifier (WIFI SSID) and an IP address information of the first mobile device, where the IP address information of the first mobile device may use an IP base address in the network segment, and may further include: channel information The heartbeat detection interval, the connection key, etc., will be described in detail in the subsequent embodiments.
步骤 102:第一移动设备和第二移动设备利用上述 WIFI连接参数建 立 WIFI连接。  Step 102: The first mobile device and the second mobile device establish a WIFI connection by using the WIFI connection parameter.
WIFI是一种可以将笔记本、 手机、 掌上电脑（PDA )等移动设备以 无线方式互相连接的技术， 无需任何中间设备。 目前市场上流行的移动 设备普遍支持 NFC和 WIFI这两种功能，因此无需对移动设备进行改动， 具有较好的实现基础。  WIFI is a technology that wirelessly connects mobile devices such as laptops, mobile phones, and PDAs without any intermediate equipment. The popular mobile devices on the market generally support the two functions of NFC and WIFI, so there is no need to change the mobile device, and it has a good implementation basis.
在本步骤中， 具体可以由第二移动设备向第一移动设备发送 WIFI 连接请求， 该连接请求中可以包括： 第二移动设备的 IP地址信息， 该 IP 地址信息通常可以采用上述 IP基址加偏移地址的方式，即 IP基址 +offset。 第一移动设备接收到 WIFI连接请求后向第二移动设备发送 WIFI连接确 认响应。  In this step, the second mobile device may send a WIFI connection request to the first mobile device, where the connection request may include: IP address information of the second mobile device, where the IP address information may be generally added by using the IP address. The way to offset the address, that is, the IP base address + offset. After receiving the WIFI connection request, the first mobile device sends a WIFI connection confirmation response to the second mobile device.
步骤 103:第一移动设备利用上述 WIFI连接向第二移动设备发送传 输文件发现列表中的一个或多个文件。  Step 103: The first mobile device sends one or more files in the transmission file discovery list to the second mobile device by using the WIFI connection.
WIFI连接的有效范围通常在 100米范围， 连接稳定， 完全可以满足 移动设备之间的文件传输需求， 目前主流 WIFI芯片均支持 802.11g, 速 度能够达到 5~7MB/s, 适合传输大数量的文件。 其中， 在进行文件传输时可以采用但不限于： WIFI ad-hoc技术或者 WIFI direct技术。 The effective range of WIFI connection is usually in the range of 100 meters. The connection is stable and can fully meet the file transmission requirements between mobile devices. At present, mainstream WIFI chips support 802.11g, and the speed can reach 5~7MB/s, which is suitable for transmitting a large number of files. . Among them, the file transmission can be used but not limited to: WIFI ad-hoc technology or WIFI direct technology.
另外， 触发文件传输时， 可以由第一移动设备主动推送文件发现列 表中的一个或多个文件， 也可以由第二移动设备 "拉取" 文件发现列表 中的一个或多个文件， 具体将在后续实施例中描述。  In addition, when the file transfer is triggered, one or more files in the file discovery list may be actively pushed by the first mobile device, or one or more files in the file discovery list may be "pushed" by the second mobile device, specifically It is described in the subsequent embodiments.
在文件传输过程中第一移动设备和第二移动设备之间会发送心跳报 文来确定 WIFI连接是否断开，如果 WIFI连接断开则可以选择终止文件 传输或重新建立 WIFI连接。  During the file transmission process, a heartbeat message is sent between the first mobile device and the second mobile device to determine whether the WIFI connection is disconnected. If the WIFI connection is disconnected, the file transmission may be terminated or the WIFI connection may be re-established.
实施例二、  Embodiment 2
下面通过实施例二对本发明提供的方法进行详细描述。 在该实施例 中， 以手机为例， 假设要将手机 A上的文件传输至手机 B , 手机 A和手 机 B均处于待连接状态， 即手机 A和手机 B的 NFC功能和 WIFI功能 均已启动， 默认处于客户端（client )模式， 则对应的方法流程可以如图 2所示， 包括以下步骤：  The method provided by the present invention will be described in detail below through the second embodiment. In this embodiment, taking a mobile phone as an example, it is assumed that the file on the mobile phone A is transmitted to the mobile phone B, and both the mobile phone A and the mobile phone B are in a state to be connected, that is, the NFC function and the WIFI function of the mobile phone A and the mobile phone B are started. The default is in the client mode. The corresponding method flow can be as shown in Figure 2. The following steps are included:
步骤 201 : 当手机 A受到用户触发后， 进入主用 （master )模式。 如果手机 A的用户欲进行文件传输， 可以通过点选手机上的某个功 能按钮或者点选要传输的文件等方式触发手机 A进入 master模式，手机 A进入 master模式后等待其他手机的配对请求。  Step 201: When the mobile phone A is triggered by the user, enter the master mode. If the user of the mobile phone A wants to transfer the file, the mobile phone A can be triggered to enter the master mode by clicking a function button on the mobile phone or clicking the file to be transmitted, and the mobile phone A enters the master mode and waits for the pairing request of the other mobile phone.
步骤 202: 手机 A接收手机 B发送的配对请求。  Step 202: The mobile phone A receives the pairing request sent by the mobile phone B.
处于 client模式的手机 B会探测到处于 NFC有效距离内的手机进行 探测， 即发送配对请求。 如果手机 A和手机 B在 NFC有效距离内， 则 手机 A会收到手机 B发送的配对请求。  The mobile phone B in the client mode detects the mobile phone within the NFC effective distance for detection, that is, sends a pairing request. If phone A and phone B are within the NFC effective distance, then phone A will receive the pairing request sent by phone B.
该配对请求中可以包括手机 B的鉴权信息，例如手机 B的身份鉴别 ID、 账号信息或者密码信息等。 The pairing request may include authentication information of the mobile phone B, for example, identity identification of the mobile phone B. ID, account information or password information.
步骤 203: 手机 A利用配对请求中的鉴权信息进行鉴权， 如果鉴权 通过则执行步骤 204; 否则， 结束流程。  Step 203: The mobile phone A uses the authentication information in the pairing request to perform authentication, and if the authentication passes, step 204 is performed; otherwise, the process ends.
在手机 A端可以预先配置鉴权机制， 可以对配对的其他移动设备进 行身份的鉴权， 例如可以通过配置白名单或者黑名单的方式， 或者通过 验证账号信息或密码信息的方式。  On the A side of the mobile phone, the authentication mechanism can be pre-configured, and the identity of other mobile devices can be authenticated. For example, the whitelist or blacklist can be configured, or the account information or password information can be verified.
如果鉴权失败， 可以直接结束流程， 如果手机 A的用户仍欲发送文 件给用户 B , 则可以通过手工^ ίι爹改手机 A的配置的方式， 例如^ ίι爹改白名 单或黑名单的方式， 使得手机 Β通过鉴权。  If the authentication fails, the process can be directly ended. If the user of the mobile phone A still wants to send the file to the user B, the user can manually change the configuration of the mobile phone A, for example, ^ ίι 爹 white list or blacklist , making the mobile phone pass the authentication.
步骤 204: 手机 Α生成文件发现列表， 并向手机 B发送 WIFI连接 参数和文件发现列表。  Step 204: The mobile phone generates a file discovery list, and sends a WIFI connection parameter and a file discovery list to the mobile phone B.
当鉴权通过后， 可以触发手机 A进行文件发现操作， 发现具有共享 权限的文件，可以将这些具有共享权限的文件的信息生成文件发现列表， 也可以将用户点选的具有共享权限的文件的信息生成文件发现列表。 其 中文件发现为已有技术， 在此不再赘述。  After the authentication is passed, the mobile phone A can be triggered to perform a file discovery operation, and the file having the sharing authority can be found, and the file discovery list can be generated by the information of the file having the sharing permission, or the file with the sharing authority selected by the user can be selected. Information generation file discovery list. The files are found in the prior art and will not be described here.
另外， 在进行上述鉴权过程之后， 针对不同的鉴权身份， 可以生成 不同权限的文件发现列表。 例如， 可以预先配置权限等级， 在鉴权过程 完成后， 可以确定出手机 B的权限等级， 然后生成该权限等级的文件发 现列表。  In addition, after performing the above authentication process, a file discovery list with different rights can be generated for different authentication identities. For example, the permission level can be pre-configured. After the authentication process is completed, the permission level of the mobile phone B can be determined, and then a file discovery list of the permission level is generated.
WIFI连接参数至少包括： WIFI网络标识和手机 A的 IP地址信息。 其中手机 A的 IP地址信息可以为网段内的 IP基址。 还可以进一步包括 以下中的至少一种： 信道信息、 心跳检测间隔、 连接密钥等。  The WIFI connection parameters include at least: a WIFI network identifier and an IP address information of the mobile phone A. The IP address information of the mobile phone A may be an IP base address in the network segment. It may further include at least one of the following: channel information, heartbeat detection interval, connection key, and the like.
其中， 信道信息为建立 WIFI连接使用的信道； 心跳检测间隔为在 WIFI连接过程中进行心跳检测的间隔， 该心跳检测用于检测 WIFI连接 是否断开； 连接密钥是 WIFI连接所使用的密钥， 用于保证文件传输的 安全性， 可以采用已有的随机算法生成。 Wherein, the channel information is a channel used to establish a WIFI connection; the heartbeat detection interval is Heartbeat detection interval during WIFI connection. The heartbeat detection is used to detect whether the WIFI connection is disconnected. The connection key is the key used by the WIFI connection to ensure the security of file transmission. The existing random algorithm can be used. generate.
至此， NFC配对过程结束， 下面开始 WIFI连接的建立过程。  At this point, the NFC pairing process ends, and the process of establishing the WIFI connection begins.
步骤 205: 手机 B向手机 A发送 WIFI连接请求。  Step 205: The mobile phone B sends a WIFI connection request to the mobile phone A.
该 WIFI建立请求中包含手机 B的 IP地址信息， 该 IP地址信息可 以采用上述的 IP基址加偏移地址的方式。  The WIFI setup request includes the IP address information of the mobile phone B, and the IP address information may adopt the foregoing IP base address plus an offset address.
步骤 206: 手机 A向手机 B发送 WIFI连接确认响应。  Step 206: The mobile phone A sends a WIFI connection confirmation response to the mobile phone B.
至此， 利用上述的 IP基址和 IP基址加偏移地址完成了手机 A和手 机 B的 WIFI连接建立过程， 下面开始文件传输过程。  So far, the WIFI connection establishment process of the mobile phone A and the mobile phone B is completed by using the above IP base address and the IP base address plus the offset address, and the file transfer process is started below.
步骤 207: 手机 B向手机 A发送包含文件发现列表中一个或多个文 件信息的文件传输请求。  Step 207: The mobile phone B sends a file transfer request including one or more file information in the file discovery list to the mobile phone A.
步骤 208: 手机 A判断手机 B的权限级别是否与文件传输请求中包 含的一个或多个文件匹配，如果是，执行步骤 212;否则，执行步骤 209。  Step 208: The mobile phone A determines whether the permission level of the mobile phone B matches one or more files included in the file transfer request. If yes, step 212 is performed; otherwise, step 209 is performed.
在手机 A中各文件可以都配置有权限级别要求，手机 B仅能够获取 其权限级别所对应的文件，如果不满足，则可以通过步骤 209至步骤 211 的权限跃迁过程实现。  In the mobile phone A, each file can be configured with a permission level requirement. The mobile phone B can only obtain the file corresponding to the permission level. If not, the mobile phone B can perform the permission transition process from step 209 to step 211.
举一个实例，假设手机 A中的文件对应的权限级别要求如表 1所示。 表 1  As an example, assume that the permission level requirements for files in phone A are as shown in Table 1. Table 1

7 限制级 假设手机 A生成的文件发现列表中包含文件 2、 3、 5、 6 , 如果手机 B的身份是访客， 则手机 B从文件发现列表中选择文件 3、 5、 6， 则权 限级别匹配， 无需进行权限跃迁； 如果手机 B从文件发现列表中选择文 件 1、 3和 4, 则由于文件 1只有超级用户才能访问， 因此， 需要手机 B 进行权限跃迁， 即执行以下步骤。  7 Restricted level Assume that the file discovery list generated by mobile phone A contains files 2, 3, 5, and 6. If the identity of mobile phone B is a visitor, then mobile phone B selects files 3, 5, and 6 from the file discovery list, and the permission level matches. If the mobile phone B selects files 1, 3 and 4 from the file discovery list, since the file 1 can only be accessed by the super user, the mobile phone B is required to perform the permission transition, that is, the following steps are performed.
步骤 209: 手机 A向手机 B发送权限跃迁邀请。  Step 209: The mobile phone A sends a permission transition invitation to the mobile phone B.
步骤 210：手机 B向手机 A发送包含权限跃迁信息的权限跃迁请求。 该权限跃迁信息可以为与手机 A约定好的个人识别号码 （ PIN ) 、 账号或密码等信息。  Step 210: The mobile phone B sends a permission transition request containing the permission transition information to the mobile phone A. The permission transition information may be a personal identification number (PIN), an account number or a password that is agreed with the mobile phone A.
步骤 211 : 手机 A利用权限跃迁信息判断手机 B是否跃迁成功， 如 果成功， 则继续执行步骤 212; 否则， 结束流程。  Step 211: The mobile phone A uses the permission transition information to determine whether the mobile phone B has transitioned successfully. If successful, proceed to step 212; otherwise, the process ends.
如果手机 B的权限跃迁到与选择的一个或多个文件匹配， 则确定跃 迁成功。 另外， 如果跃迁不成功， 除了直接流程之外， 还可以继续执行 步骤 212, 但在步骤 213中， 手机 A仅向手机 B传输与手机 B的权限级 别相匹配的文件。  If the permissions of phone B transition to match one or more selected files, then the transition is determined to be successful. In addition, if the transition is unsuccessful, in addition to the direct flow, step 212 can be continued, but in step 213, the mobile phone A transmits only the file matching the permission level of the mobile phone B to the mobile phone B.
步骤 212: 手机 A向手机 B发送文件传输确认响应。  Step 212: The mobile phone A sends a file transmission confirmation response to the mobile phone B.
在此存在两种可能性： 其一、 手机 B的用户选择文件发现列表中某 个或者某些文件， 则可以在步骤 207发送的文件传输请求中携带选择的 文件信息， 这种方式是由手机 B主动从手机 A "拉取" 文件。 其二、 手机 A的用户选择传输文件发现列表中的某个或某些文件给 手机 B , 则上述步骤 207可以是手机 A向手机 B发送文件传输请求， 携 带选择的文件信息；步骤 212可以是手机 B向手机 A发送文件传输确认 响应， 这种方式是由手机 A主动推送文件给手机 B。 这种情况下， 则不 必执行步骤 208至步骤 211的权限跃迁过程。 There are two possibilities here: First, the user of the mobile phone B selects one or some files in the file discovery list, and may carry the selected file transmission request in step 207. File information, this way is the mobile phone B actively pulls the file from the mobile phone A. Second, the user of the mobile phone A selects to transfer one or some files in the file discovery list to the mobile phone B, and the above step 207 may be that the mobile phone A sends a file transmission request to the mobile phone B, and carries the selected file information; step 212 may be The mobile phone B sends a file transmission confirmation response to the mobile phone A. In this way, the mobile phone A actively pushes the file to the mobile phone B. In this case, it is not necessary to perform the permission transition process of steps 208 to 211.
步骤 213:手机 A向手机 B传输文件发现列表中的一个或多个文件。 在文件传输结束后， 断开手机 A和手机 B之间的 WIFI连接， 重新 回到 client模式。  Step 213: The mobile phone A transmits one or more files in the file discovery list to the mobile phone B. After the file transfer is finished, disconnect the WIFI connection between mobile phone A and mobile phone B, and return to the client mode.
在手机 A向手机 B传输文件的过程中， 手机 A和手机 B之间按照 WIFI连接参数中的心跳检测间隔互相进行心跳检测， 如果检测到 WIFI 连接断开， 则文件传输中断重新建立 WIFI连接， 或者终止文件传输。  During the process of transmitting the file to the mobile phone B, the mobile phone A and the mobile phone B perform heartbeat detection according to the heartbeat detection interval in the WIFI connection parameter. If the WIFI connection is detected to be disconnected, the file transmission interruption re-establishes the WIFI connection. Or terminate the file transfer.
