Description

Method and system for automatically accessing wireless local area network

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for automatically accessing a wireless local area network and a system for automatically accessing a wireless local area network.

Background

WiFi is a technology capable of connecting terminals such as personal computers and handheld devices (e.g., PDAs and mobile phones) to each other in a wireless manner, and is originally an abbreviation of wireless fidelity, and the english language of WiFi is called wireless fidelity, and in the category of wireless local area networks, WiFi refers to "wireless compatibility authentication", which is essentially a commercial authentication, and is also a wireless networking technology, and previously, a computer is connected through a network cable, and currently, networking is performed through radio waves; it is common that a wireless router is used, and the terminal can be networked in a WiFi connection mode in an effective range covered by electric waves of the wireless router, and if the wireless router is connected with an ADSL line or another internet access line, it is also called a "hot spot".

It is known that a terminal is connected to a network in two ways, one is in a wireless way and the other is in a wired way. The Wireless connection of the network means that the terminal enters a WiFi hotspot area, scans a nearby Wireless Access Point (AP) or WiFi hotspot, and then performs SSID (Service Set Identifier) selection and password input. For any newly-entered terminal, the operation steps are that firstly, a WiFi switch is turned on in wireless setting, then AP or WiFi hotspots and the like in the range near the terminal are scanned, then, the SSID of one AP or WiFi hotspot is selected from the AP or WiFi hotspots scanned by the SSID identification, finally, the password of the AP or WiFi hotspot corresponding to the SSID is input, if the password verification is successful, the terminal can be connected with the network, otherwise, the terminal cannot be connected with the network through the AP or WiFi hotspot.

Connecting to the network in a wired manner means that the terminal is connected to the network access device through a network cable to perform network connection, and in order to facilitate identification and management, a network administrator is usually required to manually assign an IP address to a newly accessed terminal, set a mask address and a gateway address, and then the terminal can be connected to the network.

However, when there are a plurality of terminals to be configured in a network environment of a wireless lan, connecting the network by wireless or by wire requires a lot of manual operations, such as: at present, 50 intelligent terminals which need to access the wireless network exist, under the condition, passwords need to be input at least once on each terminal in a wireless mode, or IP addresses, mask addresses and gateway addresses need to be set at least once on each terminal in a wired mode, time consumption is caused, the efficiency of work is influenced, in addition, the input of the passwords for many times, or errors easily occur in the setting of the IP addresses of a plurality of terminals, the error probability is increased, the difficulty degree of network connection is increased, and resources cannot be fully and reasonably utilized.

Therefore, one technical problem that needs to be urgently solved by those skilled in the art is: the method and the system for automatically accessing the wireless local area network are used for reducing manual operation, improving the simplicity and the accuracy of accessing the wireless local area network, saving the access time of the wireless local area network and fully and reasonably utilizing resources on the premise of not increasing any hardware and other costs.

In the following, taking an example of finding a newly entering second device in the wireless local area network in a passive manner (i.e., the first device finds the second device), the specific process from step 302 to step 304 in this case will be described.

Assume that the Device name of the second Device is Device 456;

step i, the first Device scans a second Device with a specified name of Device456 through the WiFi Direct service;

The difference between this embodiment and the method embodiment 2 is that this embodiment finds a newly-entering second device in the wireless local area network in a passive manner, that is, the first device finds the second device through scanning, and the second device is a passive discovery process.

The invention searches the second equipment in a passive mode based on the WiFi Direct service, expands the way of searching the second equipment, ensures that the second equipment can be searched, thereby completing the automatic configuration of the network connection information, reducing manual operation on the premise of not increasing any hardware and other costs, improving the simplicity and accuracy of the access of the wireless local area network, saving the access time of the wireless local area network and fully and reasonably utilizing resources.

Referring to fig. 4, a flowchart of the steps of embodiment 4 of the method for automatically accessing a wireless local area network of the present invention is shown, which may specifically include the following steps:

step 401, determining whether a first device containing valid network connection information exists in the wireless local area network; if yes, go to step 402;

the first device is a wireless access device, and the first device installs and starts an AP service.

Step 402, the second device scans the appointed wireless access point AP;

the second device is a wireless access device, and the network connection information includes wireless network connection configuration information.

The wireless access point AP is an access point of a wireless network, and mainly comprises route switching access integrated equipment and pure access point equipment, wherein the integrated equipment executes access and route work, the pure access equipment is only responsible for access of a wireless client, the pure access equipment is usually used as a wireless network extension and is connected with other APs or a main AP so as to expand a wireless coverage range, and the integrated equipment is generally the core of the wireless network.

In the embodiment of the present invention, the name of the wireless access point AP may be set by default when the first device and the second device are shipped from a factory, and the name of the wireless access point AP may be set to be long and not easily confused for convenience of identification.

Step 403, when the designated wireless access point AP is scanned to be configured on a first device, the second device wirelessly connects with the first device;

step 404, if the connection is successful, determining that the newly entered second device is found in the wireless local area network.

When the second device finds the first device through WiFi hotspot scanning of the first device, the second device is connected with the first device, at the moment, validity check can be carried out, namely whether the second device and the first device are the same devices or not is judged, if the second device and the first device are the same devices, the connection is successful, and the newly-entered second device is determined to be found in the wireless local area network; and if the connection fails, determining that the newly-entered second equipment is not found in the wireless local area network.

It should be noted that, in the embodiment of the present invention, the first device and the second device may be similar devices whose names of the wireless access points AP are set by default, where the similar devices refer to devices that have names of the wireless access points AP with the same naming rule and communicate using the same transmission protocol.

Next, a specific process of the case will be described by taking an example of finding a newly-entered second device in the wireless lan by an AP + Client (wireless Client).

Assume the WiFi hotspot of the first device is AP 123;

step I, scanning a first device with a WiFi hotspot name of AP123 by a second device;

step II, when finding a first device with a WiFi hotspot name of AP123, selecting the first device by a second device, and connecting the first device with the WiFi hotspot of the first device;

step III, judging whether the second equipment is the same equipment or not, if so, executing step IV, and if not, executing step V;

step IV, the connection is successful, and the newly-entered second equipment is determined to be searched in the wireless local area network;

and V, the connection fails, and the newly entered second equipment is determined not to be found in the wireless local area network.

Step 405, transmitting, by the first device, the valid network connection information to the second device;

Step 406, after receiving the valid network connection information, the second device disconnects from the first device.

Since the second device needs to be wirelessly connected to the wireless lan, it is known that the connection between the wireless lan and the wireless access point AP cannot exist simultaneously in one terminal, and therefore, the connection between the second device and the wireless access point AP must be disconnected first to perform wireless connection with the wireless lan.

Step 407, the second device configures itself by using the effective network connection information, and accesses to the wireless local area network.

In order to make those skilled in the art better understand steps 406 to 407 of the present invention, the following is an example of finding the second device through the WiFi hotspot of the first device, and further describes an embodiment of the present invention.

Assume that the WiFi hotspot of the first device is AP123, the effective network connection information includes an SSID and a password corresponding to the SSID, the SSID is AP456, and the password corresponding to the SSID is 12345678.

Step A1, after receiving effective network connection information with SSID AP456 and password 12345678 corresponding to the SSID, the second device disconnects the connection with AP 123;

step A2, the second device scans a WiFi hotspot with SSID as AP 456;

step A3, when the second device finds that the SSID of the WiFi hotspot is AP456, connecting with the AP456 by adopting a password of 12345678;

and step A4, if the connection is successful, accessing to the wireless local area network.

In a preferred example of the present invention, the step 407 may further include the following steps:

In a specific application, the WiFi hotspot of the second device is started in an AP + Client mode, the obtained SSID can be connected in the AP + Client mode, and the WiFi hotspot of the second device can be started in the AP mode, that is, the second device can be used as the first device after configuration is completed. So that it can be used by subsequent other unconfigured second devices to continue joining in the same manner.

The method and the device search the second equipment in the AP + Client mode, expand the way of searching the second equipment, and ensure that the second equipment can be searched, thereby completing the automatic configuration of the network connection information, reducing manual operation on the premise of not increasing any hardware and other costs, improving the simplicity and accuracy of the access of the wireless local area network, saving the access time of the wireless local area network, and fully and reasonably utilizing resources.

In specific implementation, some wireless access devices can be operated only based on service requirement information, for example, a wireless camera also needs to log in service requirement information such as a user ID and a password of a server, and the wireless camera can obtain the service requirement information through the internet after being connected to the network.

Of course, there is a case where the second device is not allowed to connect to the external network, that is, when a firewall exists in the home or enterprise network environment, the second device is not allowed to connect to the internet after configuring the valid network connection information. If the second device has service requirement Information to be configured, for example, after effective network connection Information is configured for the wireless camera, service requirement Information such as a user ID and a password for logging in the server needs to be configured, and the second device may normally operate after obtaining the service requirement Information through a Routing Information Protocol (RIP). The second device may establish a channel connecting the server through the first device, where the channel may include the first device, the second device, the server, and the relay device, and the specific process is as follows:

a first step in which the first device sends a request for a direct connection with the second device to the server;

secondly, receiving information of one or more transfer devices returned by the server when the first device cannot be directly connected with the second device according to the feedback of the server to the request;

thirdly, the first equipment is connected with the one or more transfer equipment according to the information of the one or more transfer equipment; if the connection is successful, the information of the one or more transfer devices which are successfully connected is sent to the second device; the second device is used for connecting the one or more transfer devices according to the information of the one or more transfer devices and recording the information of the one or more transfer devices which are successfully connected;

fourthly, the first equipment receives and records the information of one or more transfer equipment which is successfully connected with the second equipment;

when the first device sends a data packet of service demand information to a second device, the first device sends the data packet of service demand information to at least one relay device according to information of one or more relay devices successfully connected with the second device, the relay device is used for forwarding the data packet of service demand information to the second device,

correspondingly, when the second device sends the data packet of the service requirement information to the first device, the second device sends the data packet of the service requirement information to at least one relay device according to the information of one or more relay devices successfully connected with the first device, and the relay device is used for forwarding the data packet of the service requirement information to the first device.

And after receiving the service requirement information, the second equipment adopts the service requirement information to carry out configuration, and then can normally operate.

Of course, the configuration mode of the service requirement information is only an example, and when the embodiment of the present invention is implemented, other configuration modes of the service requirement information may be set according to an actual situation, which is not limited in the embodiment of the present invention. In addition, besides the configuration mode of the service requirement information, a person skilled in the art may also adopt other configuration modes of the service requirement information according to actual needs, and the embodiment of the present invention is not limited to this.

Referring to fig. 5, a flowchart illustrating steps of embodiment 5 of a method for automatically accessing a wireless local area network according to the present invention is shown, which may specifically include the following steps:

step 501, judging whether a first device containing effective network connection information exists in the wireless local area network; if yes, go to step 502;

the first device is a wireless access device.

Step 502, when the second device finds that the preset private IP address is a non-repeated private IP address through intranet broadcasting, initiating an IP address seeking broadcast protocol in the wireless local area network by using the private IP address;

the second device is a wired access device, and the network connection information comprises wired network connection configuration information;

in this embodiment, the second device presets a private IP address in the wireless lan.

The private IP may be an IP over a local area network, and a public IP is corresponding to the private IP, that is, an IP over the internet, and with the development of the private IP network, in order to save distributable registered IP addresses, a group of IP addresses is taken out and is exclusively used for the private IP network, which is called a private IP address. These addresses are not distributed by the Internet, nor are they routed over the Internet, and although they cannot be directly connected to the Internet, they can still communicate with the Internet by technical means. The appropriate address class can be selected as required and used like a public IP address in the intranet. On the Internet, some devices that do not need to communicate with the Internet, such as printers, manageable hubs, etc., can also use these addresses to save IP address resources.

Step 503, when the first device receives the private IP address of the second device according to the IP address seeking broadcast protocol, determining to find a newly entered second device in the wireless local area network.

When there is a first device which has been configured with valid network connection information and operates normally in the wireless local area network, the first device may receive the private IP address of the second device according to the IP address broadcast protocol, and at this time, it may be determined that the newly entered second device is found in the wireless local area network.

Next, taking an example of finding a newly-entered second device in the wireless lan by using a wired access device, a specific process from step 502 to step 503 in this case will be described.

The second device presets a private IP address in the wlan, for example: 192.169.169.100, respectively; then, performing intranet broadcasting, and if the duplication is found, re-determining a new private IP address, for example: 192.169.169.145, repeating the steps until a private IP address is obtained that is not duplicated in the WLAN;

step two, after determining the private IP address, initiating a broadcast protocol for seeking the IP address in the wireless local area network;

step three, judging whether a first device receives a broadcast address which is a private IP address 192.169.169.145 and is initiated by a second device to seek an IP address broadcast protocol, if so, executing step four, otherwise, executing step five;

determining that the newly entered second equipment is found in the wireless local area network;

and fifthly, determining that the newly-entered second equipment is not found in the wireless local area network.

Step 504, after receiving the broadcast address of the second device, the first device generates an available IP address according to the IP address of the first device; the first device has its own IP address, mask address and gateway address; the wired network connection configuration information comprises an available IP address, a mask address and a gateway address;

for the wired network connection configuration information, the IP address, the mask address and the gateway address are basic information thereof, the mask address and the gateway address of the first device and the second device may be generally the same, and the IP addresses are different.

In a preferred example of the present invention, the step of generating an available IP address from the IP address of the first device itself may include the sub-steps of:

substep S41, superimposing "1" on the last bit of the first device IP address to obtain a new IP address;

substep S42, sending an ARP (address resolution Protocol) data packet to the new IP address every time of superposition, and if the new IP address has feedback information, continuing superposition; and if the new IP address has no feedback information, determining the new IP address as effective network connection information.

And repeating superposition according to the IP address of the first equipment, judging whether the superposed IP address is available after each superposition, namely sending an ARP (address resolution protocol) data packet to the IP address, judging whether feedback exists or not, and enabling the IP address to be used by the second equipment until the IP address of the second equipment is obtained, namely the IP address does not have feedback.

For example: assuming that the IP address of the first device is 192.168.0.101, adding "1" to the last bit based on the IP address of the first device to obtain a new IP address of 192.168.0.102, then sending an ARP packet to the address, i.e., 192.168.0.102, if there is no feedback, indicating that the IP address of 192.168.0.102 is available, if there is feedback, continuing to add "1" to the last bit to obtain a new IP address of 192.168.0.103, repeating the above process until an available IP address is obtained, assuming that 192.168.0.134 is available, determining the IP address of 192.168.0.134 as valid network connection information.

Of course, the above-mentioned generation manner of the IP address of the second device is only an example, and when implementing the embodiment of the present invention, other generation manners of the IP address of the second device may be set according to actual situations, which is not limited in this embodiment of the present invention. In addition, besides the above generation manner of the IP address of the second device, a person skilled in the art may also adopt other generation manners of the IP address of the second device according to actual needs, and the embodiment of the present invention is not limited to this.

Step 505, the first device broadcasts the available IP address, mask address and gateway address to the second device.

The mask address and the gateway address may be already available to the first device, and the mask address and the gateway address of the second device may be the same as the mask address and the gateway address of the first device, so that the available IP address, the mask address and the gateway address may be broadcast to the second device.

Corresponding to the above example of step 504, the available IP address 192.168.0.134 and the mask address and gateway address of the first device are sent to the second device by broadcast in this step 505.

Step 506, the second device configures itself by using the effective network connection information, and accesses to the wireless local area network.

The second device configures itself by using the available IP address, mask address and gateway address, and can access the wireless local area network.

The invention is connected to the network by the second device in a wired connection mode, the first device can automatically generate the IP address, the set mask address and the gateway address required by the second device and transmit the IP address, the set mask address and the gateway address to the second device, and the second device is connected to the network after being automatically configured by the IP address, the set mask address and the gateway address. Therefore, the method for searching the second equipment is expanded, the second equipment can be searched, the automatic configuration of the network connection information can be completed, the manual operation is reduced on the premise of not increasing any hardware and other costs, the simplicity and accuracy of the wireless local area network access are improved, the access time of the wireless local area network is saved, and the resources are fully and reasonably utilized.

The core concept of the embodiment of the present invention can also be applied to various environments, for example, when a factory produces network devices, a plurality of network devices need to be configured or upgraded at the same time, because the network devices do not have a human-computer interaction interface and cannot be configured or upgraded, but the factory has a wireless lan, and has a computer connected to the wireless lan, that is, the effective network connection information of the wireless lan is already stored in the computer, so that the computer can be used as a first device, the produced network devices can be respectively used as second devices, when the second devices are found in the wireless lan, the first device can automatically send the stored effective network connection information to the second devices, and the second devices can be automatically configured by using the effective network connection information, and accessing the wireless local area network to complete the configuration or upgrade of the second equipment.
