具体实施方式detailed description
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
本发明实施例提供一种无线网络接入的方法，如图1所示，该方法包括：An embodiment of the present invention provides a method for wireless network access, as shown in FIG. 1, the method includes:
101、检测终端的信号强度。101. Detect the signal strength of the terminal.
当终端需要接入无线网络时，首先需要打开其自身设备上接入无线网络的信号开关，以便路由器能根据终端发出的信号检测到该终端，路由器基于终端发出的信号，检测终端的信号强度。其中，步骤101中所述的终端为支持无线上网的终端，本发明实施例所采用的终端可以为：智能手机、个人计算机(Personal Computer,PC)、平板电脑等等，具体的本发明实施例不进行限制。When a terminal needs to access the wireless network, it first needs to turn on the signal switch for accessing the wireless network on its own device, so that the router can detect the terminal according to the signal sent by the terminal, and the router detects the signal strength of the terminal based on the signal sent by the terminal. Wherein, the terminal described in step 101 is a terminal that supports wireless Internet access, and the terminal used in the embodiment of the present invention may be: a smart phone, a personal computer (Personal Computer, PC), a tablet computer, etc., the specific embodiment of the present invention No restrictions are imposed.
102、根据信号强度计算终端到路由器之间的实际距离。102. Calculate the actual distance between the terminal and the router according to the signal strength.
在步骤101检测终端的信号强度之后，路由器根据该信号强度计算终端与路由器之间的实际距离。本发明实施例在计算终端到路由器之间的实际距离时，不排除外界干扰及不同终端机型造成的误差。After detecting the signal strength of the terminal in step 101, the router calculates the actual distance between the terminal and the router according to the signal strength. In the embodiment of the present invention, when calculating the actual distance between the terminal and the router, external interference and errors caused by different terminal models are not excluded.
103、将实际距离与预设的距离阈值进行比对。103. Compare the actual distance with a preset distance threshold.
在步骤102计算出的实际距离后，与预设的距离阈值进行比对，设置的距离阈值越小说明终端需要与路由器的实际距离越近才能接入到无线网络中。其中，所述预设的距离阈值是人为设置的，在设置距离阈值时可以采用但不局限于以下的方式实现，例如，设置距离阈值为40厘米，或者也可以设置距离阈值为10厘米，具体的本发明实施例对此不进行限制。After the actual distance calculated in step 102 is compared with the preset distance threshold, the smaller the set distance threshold is, the closer the actual distance between the terminal and the router is to access the wireless network. Wherein, the preset distance threshold is set artificially. When setting the distance threshold, it can be realized in the following ways, but not limited to, for example, setting the distance threshold to 40 centimeters, or setting the distance threshold to 10 centimeters, specifically Embodiments of the present invention are not limited thereto.
104、若实际距离不大于距离阈值，则将终端接入到无线接入节点AP中。104. If the actual distance is not greater than the distance threshold, connect the terminal to the wireless access node AP.
在确保能够简化终端接入无线AP时的操作程序的同时，还要确保无线AP的安全，为了防止其他终端接入到该无线AP中，路由器应该根据步骤103中的比对结果进行鉴权，若实际距离不大于距离阈值，则将终端接入到无线AP中，若实际距离大于距离阈值，则不能将终端接入到无线AP中。While ensuring that the operation procedure when the terminal accesses the wireless AP can be simplified, the security of the wireless AP must also be ensured. In order to prevent other terminals from accessing the wireless AP, the router should perform authentication according to the comparison result in step 103. If the actual distance is not greater than the distance threshold, the terminal is connected to the wireless AP; if the actual distance is greater than the distance threshold, the terminal cannot be connected to the wireless AP.
现有技术中，对于家庭场景而言，当家中有众多访客时，主人需要手动逐一在每个客人的手机、平板电脑等等终端上重复输入无线AP的密码，客人越多，主人的重复劳动量就越大，并且密码输入的过程非常容易出错。为简化访客接入无线AP的过程，本发明实施例提供的无线网络接入的方法，由路由器检测终端的信号强度，根据信号强度计算终端到路由器之间的实际距离，并将计算得到的实际距离与预设的距离阈值进行比对，当实际距离不大于距离阈值时，终端接入到无线AP中。与现有技术相比，本发明实施例通过路由器根据终端的信号强度计算得到的终端与路由器之间的实际距离，判断是否允许终端接入无线AP，而无需手动输入无线密码进行鉴权，因此，本发明实施例提供的方法能够大大简化终端接入无线AP的操作过程。In the prior art, for the family scene, when there are many visitors at home, the owner needs to manually input the password of the wireless AP on each guest’s mobile phone, tablet computer, etc. one by one. The more guests, the more repetitive work for the owner. The larger the amount, and the process of entering the password is very error-prone. In order to simplify the process for visitors to access the wireless AP, the wireless network access method provided by the embodiment of the present invention uses the router to detect the signal strength of the terminal, calculates the actual distance between the terminal and the router according to the signal strength, and calculates the actual distance between the terminal and the router. The distance is compared with the preset distance threshold, and when the actual distance is not greater than the distance threshold, the terminal is connected to the wireless AP. Compared with the prior art, the embodiment of the present invention uses the actual distance between the terminal and the router calculated by the router according to the signal strength of the terminal to determine whether to allow the terminal to access the wireless AP without manually entering the wireless password for authentication. , the method provided by the embodiment of the present invention can greatly simplify the operation process for a terminal to access a wireless AP.
进一步的，作为对上述实施例的细化和扩展，上述步骤101在检测终端的信号强度时，路由器针对不同的信号类型采用不同检测终端的信号强度的方法。本发明实施例在检测终端的信号强度时，采用但不局限于以下的方法：Further, as a refinement and extension of the above embodiment, when detecting the signal strength of the terminal in the above step 101, the router adopts different methods for detecting the signal strength of the terminal for different signal types. The embodiment of the present invention adopts but not limited to the following methods when detecting the signal strength of the terminal:
方式一：method one:
当终端发送数据信号时，检测接收数字信号时的接收信号强度指示RSSI值。When the terminal sends the data signal, it detects the received signal strength indicator RSSI value when receiving the digital signal.
路由器在检测终端的信号强度都是用统一的方法，信号强度又根据不同终端的发射功率有所差异，而不同的终端机型对应不同发射功率，因此在路由器检测接收数字信号时的RSSI值之后，查找对应终端机型的发射功率，根据发射功率的大小对RSSI值进行校准。示例性的，假设机型为M01的终端1的发射功率为40mW，机型为M030的终端2的发射功率为5mW，当终端1和终端2在距离路由器相同的位置时，路由器会检测到终端1的信号强度比终端2的信号强度大；同理的，当路由器检测到终端3和终端4的信号强度相同，且终端3与终端4发射功率相同时，则终端3和终端4与路由器之间的实际距离相同，但是不排除终端3的发射功率与终端4的发射功率不相同的情况，当终端3的发射功率比终端4的发射功率大时，终端3与路由器之间的实际距离要比终端4与路由器之间的实际距离大，当终端3的发射功率比终端4的发射功率小时，终端3与路由器之间的实际距离要比终端4与路由器之间的实际距离要小，进而路由器在根据信号强度计算终端到路由器之间的实际距离时会出现误差。因此，针对如上所述的问题，本发明实施例采用根据不同终端机型对应于不同发射功率的大小，对RSSI值进行校准。The router uses a unified method to detect the signal strength of the terminal, and the signal strength varies according to the transmission power of different terminals, and different terminal models correspond to different transmission powers, so after the router detects the RSSI value when receiving digital signals , find the transmit power of the corresponding terminal model, and calibrate the RSSI value according to the transmit power. For example, suppose the transmit power of terminal 1 whose model is M01 is 40mW, and the transmit power of terminal 2 whose model is M030 is 5mW. When terminal 1 and terminal 2 are at the same distance from the router, the router will detect the terminal The signal strength of terminal 1 is greater than that of terminal 2; similarly, when the router detects that the signal strengths of terminal 3 and terminal 4 are the same, and the transmit power of terminal 3 and terminal 4 is the same, the distance between terminal 3 and terminal 4 and the router The actual distance between them is the same, but the situation that the transmit power of terminal 3 is different from that of terminal 4 is not ruled out. When the transmit power of terminal 3 is greater than that of terminal 4, the actual distance between terminal 3 and the router is longer is greater than the actual distance between terminal 4 and the router, when the transmission power of terminal 3 is smaller than that of terminal 4, the actual distance between terminal 3 and the router is smaller than the actual distance between terminal 4 and the router, and then When the router calculates the actual distance between the terminal and the router based on the signal strength, errors will occur. Therefore, in order to solve the above problems, the embodiment of the present invention calibrates the RSSI value according to different terminal models corresponding to different transmission powers.
在实际的运行过程中，路由器会根据终端发送的数据信号，确定该终端的机型，并根据终端机型与发射功率对照表查找该终端对应的发射功率，如表1所示，表1示出了终端机型与发射功率对照表。In the actual operation process, the router will determine the model of the terminal according to the data signal sent by the terminal, and look up the corresponding transmit power of the terminal according to the terminal model and transmit power comparison table, as shown in Table 1. A comparison table of terminal models and transmit power is shown.
表1Table 1
路由器根据终端发射功率的大小对RSSI值进行校准之后，获取终端当前的RSSI值，并根据终端当前的RSSI值确定终端的信号强度，在路由器本地保存一个预设的第一映射关系表，获取终端与路由器之间的实际距离，其中，该表中记录了RSSI值与实际距离之间的一一对应关系。After the router calibrates the RSSI value according to the transmit power of the terminal, it obtains the current RSSI value of the terminal, and determines the signal strength of the terminal according to the current RSSI value of the terminal, saves a preset first mapping relationship table locally in the router, and obtains the terminal The actual distance from the router, wherein the table records the one-to-one correspondence between the RSSI value and the actual distance.
其中，路由器在根据终端机型与发射功率对照表查找该终端对应的发射功率时，本发明实施例可以采用但不局限于以下的方式实现，路由器在终端机型与发射功率对照表中逐次查找终端对应的发射功率；或者，通过二分法的方式在终端机型与发射功率对照表中查找终端对应的发射功率。具体的本发明实施例不进行限制。Wherein, when the router looks up the transmit power corresponding to the terminal according to the terminal model and transmit power comparison table, the embodiment of the present invention can be implemented in the following manner, but not limited to, the router searches the terminal model and transmit power comparison table one by one The transmit power corresponding to the terminal; or, look up the transmit power corresponding to the terminal in the terminal model and transmit power comparison table by means of dichotomy. The specific embodiments of the present invention are not limited.
方式二：Method 2:
无线桥接到终端创建的虚拟AP中，检测虚拟AP的分贝dBm值。The wireless bridge connects to the virtual AP created by the terminal, and detects the decibel dBm value of the virtual AP.
路由器会自动扫描周围的无线AP，并查看能够桥接的无线AP，在路由器进行无线AP扫描过程中获取无线AP中携带的dBm值，根据所述dBm值可以检测出终端的信号强度，根据信号强度计算所述终端到路由器之间的实际距离。在具体实施时，首先终端创建虚拟AP，路由器桥接到终端创建的虚拟AP中，并检测dBm值。其中，所述dBm值与RSSI值都可以用来表示终端的信号强度，其中，dBm值与RSSI值可以进行相互转换。The router will automatically scan the surrounding wireless APs and check the wireless APs that can be bridged. During the wireless AP scanning process of the router, the dBm value carried in the wireless AP is obtained. According to the dBm value, the signal strength of the terminal can be detected. According to the signal strength Calculate the actual distance between the terminal and the router. During specific implementation, firstly, the terminal creates a virtual AP, and the router bridges into the virtual AP created by the terminal, and detects the dBm value. Wherein, both the dBm value and the RSSI value can be used to represent the signal strength of the terminal, wherein the dBm value and the RSSI value can be converted to each other.
路由器获取终端当前的dBm值，并根据终端当前的dBm值确定终端的信号强度，在路由器本地保存一个预设的第二映射关系表，获取终端与路由器之间的实际距离，其中，该表中记录了dBm值与实际距离之间的一一对应关系。The router obtains the current dBm value of the terminal, and determines the signal strength of the terminal according to the current dBm value of the terminal, saves a preset second mapping relationship table locally in the router, and obtains the actual distance between the terminal and the router, wherein, in the table A one-to-one correspondence between dBm values and actual distances is recorded.
可选的，为了进一步的确保无线AP的安全，路由器在检测终端的信号强度之前，停止向终端广播无线AP的名称，以使得终端不显示无线AP的名称。在本发明实施例的一种实现方式中，路由器停止向终端广播无线AP的名称时，路由器可以继续检测到终端的信号强度，当路由器根据信号强度计算出终端与路由器之间的实际距离不大于所述距离阈值时，路由器广播无线AP的名称，并将终端接入到无线AP中；在本发明实施例的另一种实现方式中，路由器停止向终端广播无线AP的名称，且终端知道该无线AP的名称时，终端用户可以手动输入无线AP的名称，并向路由器发送接入无线AP的请求信息，路由器在接收到接入无线AP的请求信息时，向终端发送等待测距的提示信息，当路由器根据信号强度计算出终端与路由器之间的实际距离不大于所述距离阈值时，将终端接入到无线AP中。其中，路由器停止向终端广播无线AP的名称，所述名称可以是无线AP的服务集标识(Service SetIdentifier,SSID),也可以是用户人为设置的无线AP的名称，如WX-3003等，本发明实施例对无线AP的名称不进行限制。Optionally, in order to further ensure the security of the wireless AP, the router stops broadcasting the name of the wireless AP to the terminal before detecting the signal strength of the terminal, so that the terminal does not display the name of the wireless AP. In an implementation of the embodiment of the present invention, when the router stops broadcasting the name of the wireless AP to the terminal, the router can continue to detect the signal strength of the terminal, and when the router calculates the actual distance between the terminal and the router according to the signal strength is not greater than When the distance threshold is reached, the router broadcasts the name of the wireless AP and connects the terminal to the wireless AP; in another implementation of the embodiment of the present invention, the router stops broadcasting the name of the wireless AP to the terminal, and the terminal knows the name of the wireless AP When the name of the wireless AP is selected, the terminal user can manually enter the name of the wireless AP, and send the request information to the router to access the wireless AP. When the router receives the request information to access the wireless AP, it will send a prompt message to the terminal to wait for ranging , when the router calculates according to the signal strength that the actual distance between the terminal and the router is not greater than the distance threshold, connect the terminal to the wireless AP. Wherein, the router stops broadcasting the name of the wireless AP to the terminal, and the name may be the service set identifier (Service SetIdentifier, SSID) of the wireless AP, or the name of the wireless AP artificially set by the user, such as WX- 3003, etc., the present invention The embodiment does not limit the name of the wireless AP.
其中，本发明实施例在向终端发送等待测距的提示信息时可以采用但不局限于以下的方式实现，例如，路由器可以采用以对话框的形式向终端发送等待测距的提示信息；或者，也可以不对终端发送的接入无线AP的请求信息进行响应，而是等待路由器根据终端的信号强度计算出终端与路由器之间的实际距离不大于所述距离阈值之后，将终端接入到无线AP中。具体的本发明实施例不进行限定。Wherein, in the embodiment of the present invention, the prompt information of waiting for ranging may be sent to the terminal in the following ways, but not limited to, for example, the router may send the prompt information of waiting for ranging to the terminal in the form of a dialog box; or, It is also possible not to respond to the request information sent by the terminal to access the wireless AP, but to wait for the router to calculate the actual distance between the terminal and the router according to the signal strength of the terminal, and then connect the terminal to the wireless AP. middle. The specific embodiments of the present invention are not limited.
在实际应用场景中，路由器停止向终端广播无线AP的名称应用于家庭的互动游戏中。将无线AP隐藏在家中的某个角落里,小明、小花、小红三人进行比赛，查看哪个终端会在最短的时间内接入到无线AP，小明、小花、小红三人的终端需要在与路由器的预设距离内才能够接入无线AP，此外，路由器也可以设置在终端与路由器的预设距离内，通过摇动终端的方式建立终端与无线AP之间的无线网络，以便增加用户对简化接入无线AP操作程序的体验。其中，路由器对摇动终端的次数和方式进行设置，以便能够使得终端快速的接入到无线AP中，路由器可以设置终端摇动一次，也可以设置终端摇动两次，路由器根据终端摇动的次数判断是否将终端接入到无线AP中。In an actual application scenario, the router stops broadcasting the name of the wireless AP to the terminal and is used in interactive games at home. Hide the wireless AP in a corner of the home, Xiaoming, Xiaohua, and Xiaohong compete to see which terminal will connect to the wireless AP in the shortest time. The terminals of Xiaoming, Xiaohua, and Xiaohong need to be in the The wireless AP can only be accessed within the preset distance from the router. In addition, the router can also be set within the preset distance between the terminal and the router, and the wireless network between the terminal and the wireless AP can be established by shaking the terminal to increase user confidence. Simplify the experience of accessing wireless AP operation procedures. Among them, the router sets the times and ways of shaking the terminal so that the terminal can be quickly connected to the wireless AP. The router can set the terminal to shake once, or set the terminal to shake twice. The terminal accesses the wireless AP.
可选的，由于路由器可以虚拟出多个无线AP，且每个无线AP都有其唯一的名称，因此路由器也可以向终端广播所有的无线AP的名称，以使得用户在终端上选择需要接入的无线AP，其中，由同一个路由器虚拟的多个无线AP都是由路由器创建的子网，都可以将终端接入到无线网络中。Optionally, since the router can virtualize multiple wireless APs, and each wireless AP has its unique name, the router can also broadcast the names of all wireless APs to the terminal, so that the user can select the desired access point on the terminal. Wireless APs, where multiple wireless APs virtualized by the same router are all subnets created by the router, and can connect terminals to the wireless network.
进一步的，当路由器检测到终端与路由器之间的实际距离不大于距离阈值时，路由器接收终端上报的对应无线AP的无线密码，在根据无线密码对终端进行鉴权，若终端上报的无线密码正确，则将该终端接入到无线AP中。为了能够更好的简化终端接入无线AP的操作程序，在本发明实施例的一种实现方式中，终端上报的无线密码为广播无线AP的名称时，路由器通过公钥加密并绑定于名称的无线密码，路由器在广播无线AP时，将该无线AP的密码通过加密算法绑定到无线AP名称中，终端显示到该无线AP的名称时，通过与无线AP加密算法对应的解密算法对无线AP名称中绑定的无线密码进行解密，将解密后的无线密码上报给路由器，实现终端接入到无线AP中。在本发明实施例的另一种实现方式中，终端上报的无线密码为终端此前缓存过的无线密码，路由器本地中记录通过鉴权之后的终端，而通过路由器鉴权之后的终端本地会缓存接入无线AP的无线密码，以便后续需要接入对应的无线AP时，无需鉴权就可接入到对应的无线AP中。在本发明实施例的第三种实现方式中，当终端中显示出无线AP的名称时，用户可以采用手动输入无线密码的方式，等待路由器的鉴权，若输入的无线密码正确，则将终端接入到无线AP中。Further, when the router detects that the actual distance between the terminal and the router is not greater than the distance threshold, the router receives the wireless password of the corresponding wireless AP reported by the terminal, and authenticates the terminal according to the wireless password. If the wireless password reported by the terminal is correct , then connect the terminal to the wireless AP. In order to better simplify the operation procedure for the terminal to access the wireless AP, in an implementation of the embodiment of the present invention, when the wireless password reported by the terminal is the name of the broadcast wireless AP, the router encrypts it with the public key and binds it to the name When the router broadcasts the wireless AP, it binds the password of the wireless AP to the name of the wireless AP through an encryption algorithm. When the terminal displays the name of the wireless AP, it uses the decryption algorithm corresponding to the encryption algorithm of the wireless AP to The wireless password bound in the AP name is decrypted, and the decrypted wireless password is reported to the router, so that the terminal is connected to the wireless AP. In another implementation of the embodiment of the present invention, the wireless password reported by the terminal is the wireless password previously cached by the terminal. Enter the wireless password of the wireless AP, so that when you need to access the corresponding wireless AP later, you can access the corresponding wireless AP without authentication. In the third implementation of the embodiment of the present invention, when the name of the wireless AP is displayed in the terminal, the user can manually enter the wireless password and wait for the authentication of the router. If the wireless password entered is correct, the terminal Connect to the wireless AP.
可选的，当路由器检测到终端与路由器之间的实际距离不大于距离预设值时，取消对无线密码的接收及对终端的鉴权，并将终端接入到无线AP中。这里所说的取消对无线密码的接收及对终端的鉴权并不是说任何终端都可以无条件的接入到无线AP中，如前所述的，路由器需要根据终端的信号强度计算出终端与路由器的实际距离是否不大于预设的距离阈值之后，才能够将终端接入到无线AP中；若终端与路由器之间的实际距离小于预设的距离阈值，即使路由器取消对无线密码的接收及对终端的鉴权，也不能将与路由器之间的实际距离小于距离阈值的终端接入到无线AP中。Optionally, when the router detects that the actual distance between the terminal and the router is not greater than the distance preset value, it cancels the reception of the wireless password and the authentication of the terminal, and connects the terminal to the wireless AP. The cancellation of the reception of the wireless password and the authentication of the terminal mentioned here does not mean that any terminal can be unconditionally connected to the wireless AP. As mentioned above, the router needs to calculate the connection between the terminal and the router based on the signal strength of the terminal. The terminal can be connected to the wireless AP only after the actual distance is not greater than the preset distance threshold; if the actual distance between the terminal and the router is less than the preset distance threshold, even if the router cancels the reception of the wireless password and the The authentication of the terminal also cannot connect the terminal whose actual distance to the router is smaller than the distance threshold to the wireless AP.
将终端接入到无线AP中还可以采用路由器接收终端上报的客户端标识，根据客户端标识对终端进行鉴权并将终端接入到无线AP中。基于路由器检测到终端与路由器之间的实际距离不大于距离预设值，终端上报其自身的客户端标识，等待路由器的鉴权，当终端上报的客户端标识通过路由器的鉴权之后，终端会自动接入无线AP中。其中，所述客户端标识可以通过Token进行标识，也可以通过ticket进行标识，具体的本发明实施例对此不进行限制。Connecting the terminal to the wireless AP may also use the router to receive the client ID reported by the terminal, authenticate the terminal according to the client ID, and connect the terminal to the wireless AP.
