Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to solve the problem of the prior art, embodiments of the present invention provide a method, an apparatus, and a system for a terminal to access a network from the perspective of a first terminal and a second terminal, respectively.

First, a method for a terminal to access a network according to an embodiment of the present invention is described below from the perspective of a first terminal.

The first terminal is provided with an input device, and the first terminal communicates with a relay terminal having a wireless routing function, wherein the communication mode between the first terminal and the relay terminal may be wired communication or wireless communication. For example, the first terminal may utilize an access network identifier of the wireless network generated by the relay terminal to implement access to the wireless network, thereby implementing wireless communication with the relay terminal; or the network cable can be connected with the transfer terminal to realize the wired communication with the transfer terminal.

Wherein the first terminal includes, but is not limited to, a smart phone, a tablet computer, and a desktop computer; the input devices include, but are not limited to, a keyboard and a touch screen.

It is emphasized that the first terminal communicates with the relaying terminal, which is capable of receiving the multicast address sent by the first terminal and forwarding the multicast address, which the second terminal is capable of receiving in promiscuous mode.

It is to be understood that the transit terminal includes, but is not limited to, a wireless router. The second terminal is an intelligent device which can be accessed to the wireless network, and the second terminal can be provided with an input device or not.

As shown in fig. 1, a method for a terminal to access a network provided from a first terminal according to an embodiment of the present invention may include the following steps:

s101: obtaining an access network identifier through the input device, wherein the access network identifier is access information required for accessing the wireless network generated by the transit terminal;

the first terminal obtains the access network identifier through an input device configured by the first terminal, and can access the wireless network generated by the transfer terminal through the access network identifier to realize communication with the transfer terminal, so as to realize wireless internet access. After the first terminal establishes communication connection with the transit terminal, when the second terminal needs to be accessed to the wireless network, the first terminal can acquire an access network identifier accessed to the transit terminal through an input device configured by the first terminal, so as to execute the step of sending the access network identifier to the second terminal.

It can be understood that, when the first terminal accesses the wireless network generated by the transit terminal for the first time, the access network identifier input by the input device may be stored locally at the first terminal, and when the access network identifier needs to be used to access the corresponding wireless network or needs to be sent to the second terminal, the access network identifier may be directly obtained locally, thereby avoiding the need to obtain the access network identifier through the input device each time, reducing the complexity of operation, and improving the processing speed.

S102: coding the access network identification according to a preset coding mode to obtain target transmission data;

after the access network identification accessed to the wireless network is obtained, the access network identification is coded according to a preset coding mode, and therefore coded target transmission data are obtained.

For example, the access network identifier includes a user name and a password, where the user name is ABC and the password is 123, and at this time, the user name and the password may be encoded to obtain encoded target transmission data of 123 ABC.

It should be emphasized that the predetermined encoding method may be any encoding method for data in the prior art, and is not limited to the above example.

S103: embedding the target transmission data into a plurality of preset multicast addresses according to a preset data embedding mode to obtain a plurality of target multicast addresses to be transmitted, wherein the plurality of target multicast addresses comprise the complete content of the target transmission data, each target multicast address comprises the data content of different parts of the target transmission data, and each target multicast address carries the sequence position information of the included part of the data content in all the parts;

after the target transmission data is obtained, the target transmission data needs to be transmitted, and then according to a preset data embedding manner, the operation of embedding the target transmission data into a plurality of preset multicast addresses may be: dividing the target transmission data into N parts, embedding the sequence position information corresponding to each part and each part into a preset multicast address to obtain a plurality of target multicast addresses, so that the target multicast addresses can be determined, the target multicast addresses can be orderly sent to a transfer terminal, the transfer terminal can forward the target multicast addresses, wherein N is more than or equal to 0, and the speed of accessing a second terminal to a wireless network is improved.

For example, the obtained target transmission data is ABC123, the target transmission data can be divided into three parts, AB, C1 and 23, and the sequence position information corresponding to AB in the first part is 1; the sequence position information corresponding to the second part C1 is 2; the sequence position information corresponding to 23 of the third part is 3. That is, the sequence numbers corresponding to 1-3 are the sequence numbers for correctly ordering the three parts AB, C1, and 23.

At this time, the target transmission data may be embedded into 3 preset multicast addresses 225.x.1.y to 225.x.3.y, and 3 target multicast addresses are obtained: 225, a.1.b, 225, c.2.1 and 225.2.3.3, that is, the 3 destination multicast addresses include the complete content of the destination transmission data ABC123, and each destination multicast address includes the data content of different parts of ABC123, and each destination multicast address carries the sequence position information corresponding to the included data content.

It should be emphasized that the above embedding manner for obtaining the target transmission data as ABC123 is merely an example, and the embodiments of the present invention include, but are not limited to, the target transmission data ABC123 and the above mentioned embedding manner.

In addition, it can be understood by those skilled in the art that the predetermined multicast address can be selected from the range of 224.0.0.0 to 239.255.255.255.

S104: and sending the target multicast addresses to the transit terminal so that the transit terminal can multicast the target multicast addresses, after receiving the target multicast addresses in a hybrid mode, a second terminal determines a reduction result corresponding to the target multicast addresses based on the preset data embedding mode, decodes the reduction result based on a decoding mode corresponding to the preset coding mode to obtain the access network identifier, and accesses the wireless network by using the access network identifier.

After obtaining each target multicast address, the first terminal sends the target multicast addresses to the transit terminal through the wireless network, and the transit terminal multicasts the target multicast addresses after receiving the target multicast addresses. It can be understood that the first terminal may send the plurality of target multicast addresses to the transit terminal in a loop, so that when a packet loss occurs, the transit terminal may still receive the complete plurality of target multicast addresses.

The second terminal in the promiscuous mode can receive all the data packets, namely can receive a plurality of target multicast addresses multicast by the transit terminal; after receiving the target multicast addresses, the second terminal restores the target multicast addresses based on a preset data embedding mode to obtain target transmission data; and decoding the target transmission data by using a decoding mode corresponding to a preset coding mode to obtain an access network identifier corresponding to the target transmission data, so that the second terminal can access the wireless network generated by the transfer terminal by using the access network identifier, and further the second terminal can realize wireless network access without depending on an input device of the second terminal, thereby reducing the dependence on the input device when accessing the wireless network and improving the speed of accessing the second terminal to the wireless network.

That is, when the second terminal is a device such as a smart camera or a smart socket without an input device, the wireless network can be accessed by the above method.

It is emphasized that promiscuous mode means that a terminal is able to receive all packets that go through the network card of the terminal, regardless of whether the destination address to which the packet is to be sent is the terminal.

In the embodiment of the invention, a first terminal obtains an access network identifier through an input device of the first terminal, and the first terminal can be accessed to a wireless network corresponding to the access network identifier through the access network identifier; coding the access network identification according to a preset coding mode to obtain target transmission data; embedding the target transmission data into a plurality of preset multicast addresses according to a preset data embedding mode to obtain a plurality of target multicast addresses, so that the plurality of target multicast addresses carry the complete content of the target transmission data, and each target multicast address carries the position information of the carried data in the target transmission data; the target multicast address is sent to the transfer terminal, the transfer terminal multicasts the target multicast addresses to the second terminal, the second terminal receives the target multicast addresses in a hybrid mode, then target transmission data are obtained through restoration according to a preset data embedding mode, the target transmission data are decoded, an access network identification of the transfer terminal is obtained, the access network identification is used for accessing a wireless network generated through the transfer terminal, the second terminal does not need to rely on an input device of the second terminal to achieve wireless network access, the dependence degree of the terminal access wireless network on the input device is reduced, and the speed of the terminal access wireless network is increased.

Optionally, the embedding the target transmission data into a plurality of preset multicast addresses according to a preset data embedding manner to obtain a plurality of target multicast addresses to be transmitted may include:

numbering the sub-transmission data according to the segmentation sequence;

It can be understood that, in this implementation manner, the preset data embedding manner may specifically be: dividing target transmission data into preset shares, for example: the target transmission data ABC123 may be divided into three parts, AB, C1 and 23, or the target transmission data ABC123 may be divided into six parts, A, B, C, 1, 2 and 3.

The preset sub-transmission data is obtained after the division into the preset parts, and the division mode can realize the control of the length of the sub-transmission data (wherein, when the preset parts are divided into three parts of AB, C1 and 23, the length of each sub-transmission data can be controlled to be 2 bytes, and when the preset parts are divided into six parts of A, B, C, 1, 2 and 3, the length of each sub-transmission data can be controlled to be 1 byte), namely, the larger the value corresponding to the preset part is, the more the number of the divided sub-transmission data is, and the shorter the length of each sub-transmission data is correspondingly.

Then, numbering each sub-transmission data according to the segmentation sequence to realize the ordered organization of each sub-transmission data; and embedding each sub-transmission data and the number corresponding to the sub-transmission data into a preset multicast address to obtain a preset target multicast address, and determining the sequence position of the corresponding sub-transmission data in the target transmission data according to each number, so that the second terminal can accurately restore the target transmission data according to the number.

It is to be understood that the dividing order may be a dividing order in which the target transmission data is divided from left to right, or may be a dividing order in which the target transmission data is divided from right to left, and is not limited herein.

It should be emphasized that, a person skilled in the art can set the value corresponding to the predetermined portion according to the requirement of transmission precision, and the specific value is not limited herein.

Optionally, the dividing the target transmission data into preset shares to obtain preset sub-transmission data may include:

It is understood that, in this implementation manner, since the shorter the transmitted data is, the smaller the error rate is, in order to ensure the transmission accuracy and the reception accuracy, the number of bytes included in the target transmission data may be used as a division number, that is, each byte in the target transmission data is divided into one sub-transmission data, the number of bytes transmitted per sub-transmission is reduced, the accuracy and the speed of transmission of each sub-transmission data are enhanced, and the speed of extracting the sub-transmission data from the plurality of target multicast addresses after the second terminal receives the plurality of target multicast addresses including each sub-transmission data is enhanced.

For example: when the target transfer data is ABC123, the ABC123 is divided into A, B, C, 1, 2, and 3 parts according to the number of bytes included in the target transfer data as the number of divisions. The 6 parts are respectively embedded into 6 preset multicast addresses 225.115.1. y-225.115.6. y, and 6 target multicast addresses are respectively obtained as follows: 225.115.1.65, 225.115.2.66, 225.115.3.67, 225.115.4.1, 225.115.5.2 and 225.115.6.3.

and embedding each sub-transmission data into the fourth byte in each preset multicast address respectively, and embedding the number corresponding to each sub-transmission data into the third byte in each preset multicast address respectively.

It is to be understood that, in this implementation, after the target transfer data is divided by taking the number of bytes included in the target transfer data as the number of divisions, the sub-transmission data obtained by the division may be embedded into the fourth byte of each preset multicast address, and the number corresponding to each sub-transmission data is respectively embedded into the third byte of the corresponding preset multicast address to obtain a plurality of target multicast addresses, thereby realizing the ordered organization of the plurality of target multicast addresses, and the second terminal may extract the respective sub-transmission data from the fourth byte in the plurality of destination multicast addresses according to the predetermined data embedding manner, and the sub-transmission data can be arranged according to the number extracted from the third byte in the target multicast address, so that the target multicast addresses are restored into the target transmission data.

Optionally, the access network identification may include: a network name and a network password for the wireless network.

It will be appreciated that in such an implementation, the access network identification may be a network name and a network password of the wireless network generated by the transit terminal. In the coverage range of the wireless network, any terminal can utilize the network name and the network password to realize the access to the wireless network after obtaining the network name and the network password.

It is emphasized that any terminal refers to an intelligent terminal capable of accessing a wireless network. And the access network identification includes, but is not limited to, the network name, network password, and other customized information for the wireless network to be accessed. The other user-defined information can be a terminal identifier of the first terminal, so that after the second terminal obtains the terminal identifier, whether the terminal identifier is a safety identifier is judged, if yes, the network name and the network password are used for accessing the wireless network, and if not, the operation of accessing the wireless network is not executed.

coding the network name, the network password, a first length value corresponding to the network name and a second length value corresponding to the network password according to a preset coding mode to obtain target transmission data, wherein the preset coding mode comprises a preset principle so as to code the first length value and the second length value by utilizing the preset principle;

correspondingly, after determining the restoration results corresponding to the target multicast addresses based on the preset data embedding manner, the second terminal obtains the first length value and the second length value from the restoration results based on the decoding manner corresponding to the preset principle, judges whether the restoration results are the target transmission data or not based on the first length value and the second length value, and executes the step of decoding the restoration results based on the decoding manner corresponding to the preset encoding manner when the judgment result is yes.

It can be understood that, in this implementation manner, after obtaining the network name and the network password for accessing the wireless network through the input device, the first terminal obtains a first length value corresponding to the network name and a second length value corresponding to the network password, and encodes the first length value, the second length value, the network name and the network password, that is, encodes the target transmission data by using the first length value, the second length value, the network name and the network password.

It can be understood by those skilled in the art that, when the length value is encoded together with the network name and the network password, the position of the length value can be set according to a preset rule, and the second terminal recognizes the position of the length value and the length value corresponding to the position of the length value based on the preset rule.

In addition, when the relay terminal forwards the plurality of target multicast addresses carrying the target transmission data to the second terminal, the second terminal restores the sub-transmission data carried in the plurality of target multicast addresses according to a preset data embedding mode to obtain a restoration result; finding a first length value and a second length value according to a preset rule, judging whether the restored network name and network password are received completely or not according to the first length value and the second length value, and decoding the restored result by using a decoding mode corresponding to a preset coding mode when the network name and the network password are judged to be received completely; when the receiving is judged to be incomplete, the restoration result is not decoded, so that the decoding accuracy is improved; and after the network name and the network password are obtained, accessing the wireless network by using the network name and the network password.

The method for accessing the network by the terminal provided by the embodiment of the invention is described from the perspective of the second terminal.

It should be noted that the second terminal is an intelligent device that can access a wireless network, and may or may not be provided with an input device, that is, the second terminal may be a device that does not have an input device, such as an intelligent camera and an intelligent socket. The wireless network generated by the second terminal accessing the transit terminal does not need to rely on the input device carried by the second terminal. The transit terminal has a wireless routing function, and the transit terminal includes, but is not limited to, a router having a wireless routing function.

The first terminal is provided with an input device and communicates with a transit terminal with a wireless routing function, wherein the communication mode of the first terminal and the transit terminal can be wired communication or wireless communication. For example, the first terminal may utilize an access network identifier of the wireless network generated by the relay terminal to implement access to the wireless network, thereby implementing wireless communication with the relay terminal; or the network cable can be connected with the transfer terminal to realize the wired communication with the transfer terminal.

It is emphasized that the first terminal communicates with the relaying terminal, which is able to receive the multicast address sent by the terminal and to forward the multicast address, which the second terminal is able to receive in promiscuous mode.

As shown in fig. 2, a method for a terminal to access a network provided from a second terminal perspective according to an embodiment of the present invention may include the following steps:

s201: receiving a plurality of target multicast addresses multicast by a transit terminal in a promiscuous mode, wherein the target multicast addresses are multicast by the transit equipment after receiving the target multicast address sent by a first terminal, and the first terminal generates the target multicast address according to the method for accessing the terminal to the network from the perspective of the first terminal and sends the target multicast address to the transit terminal;

the second terminal starts a promiscuous mode, and in the promiscuous mode, the second terminal can receive all data packets passing through the network card of the second terminal, namely can receive a plurality of target multicast addresses multicast by the transit terminal, wherein the plurality of target multicast addresses are sent by the first terminal and forwarded by the transit terminal.

The generation method and the transmission method of the multiple target multicast addresses may refer to the related description in the first terminal embodiment, which is not described herein again.

S202: determining restoration results corresponding to the plurality of target multicast addresses based on the preset data embedding mode;

and after receiving the plurality of target multicast addresses, the second terminal restores the plurality of target multicast addresses according to a preset data embedding mode for the sub-transmission data to obtain restoring results corresponding to the plurality of target multicast addresses.

S203: decoding the reduction result based on a decoding mode corresponding to the preset coding mode to obtain an access network identifier;

and decoding the reduction result according to a decoding mode corresponding to a preset coding mode to obtain an access network identifier corresponding to the target transmission data.

It is emphasized that the access network identification includes, but is not limited to, the network name, network password, and other customized information for the wireless network to be accessed. The other user-defined information may be a terminal identifier of the first terminal, so that after the second terminal obtains the terminal identifier, it is determined whether the terminal identifier is a security identifier, if so, the obtained access network identifier (e.g., a network name and the network password) is used to access the wireless network, and if not, the operation of accessing the wireless network is not performed.

S204: and accessing the wireless network generated by the transit terminal by using the access network identification.

And accessing the wireless network generated by the transit terminal by using the access network identifier. It is understood that the access to the wireless network using the access network identification (e.g., network name and network password) belongs to the prior art, and the specific operation of accessing the wireless network is not limited herein.

In the embodiment of the present invention, the second terminal receives a plurality of target multicast addresses sent by the transit terminal, where the plurality of target multicast addresses are generated by: a first terminal obtains an access network identification through an input device of the first terminal, and the first terminal can be accessed to a wireless network corresponding to the access network identification through the access network identification; coding the access network identification according to a preset coding mode to obtain target transmission data; and according to a preset data embedding mode, embedding the target transmission data into a plurality of preset multicast addresses to obtain a plurality of target multicast addresses, so that the plurality of target multicast addresses carry the complete content of the target transmission data, and each target multicast address carries the position information of the carried data in the target transmission data. And then the first terminal sends the target multicast address to a transfer terminal, and the transfer terminal multicasts the target multicast addresses to a second terminal, so that the second terminal receives the target multicast addresses in a hybrid mode, restores the target transmission data according to a preset data embedding mode, decodes the target transmission data to obtain an access network identifier of the transfer terminal, and accesses a wireless network generated by the transfer terminal by using the access network identifier, so that the second terminal does not need to rely on an input device of the second terminal to realize the access of the wireless network, the dependence degree of the terminal access wireless network on the input device is reduced, and the speed of the second terminal accessing the wireless network is improved.

Optionally, the determining the restoration result corresponding to the plurality of target multicast addresses based on the preset data embedding manner may include:

It can be understood that, in this implementation manner, after receiving a plurality of target multicast addresses, the second terminal extracts a plurality of pieces of sub-transmission data and numbers corresponding to the plurality of pieces of sub-transmission data from each target multicast address according to a preset data embedding manner; and sequencing the plurality of sub-transmission data according to the extracted serial number values to obtain target transmission data.

Specifically, the first terminal may encode the access network identifier only according to a preset encoding mode to obtain the target transmission data, or encode the network name and the network password according to the preset encoding mode, and encode a first length value corresponding to the network name and a second length value corresponding to the network password in the access network identifier to obtain the target transmission data. Optionally, when the first terminal encodes the network name, the network password, the first length value corresponding to the network name, and the second length value corresponding to the network password according to a preset encoding mode, to obtain target transmission data, where the preset encoding mode includes a preset principle, so as to encode the first length value and the second length value by using the preset principle;

accordingly, after determining the restoration results corresponding to the target multicast addresses based on the preset data embedding manner, the method may further include:

and obtaining the first length value and the second length value from the reduction result based on the decoding mode corresponding to the preset principle, judging whether the reduction result is the target transmission data or not based on the first length value and the second length value, and executing the step of decoding the reduction result based on the decoding mode corresponding to the preset coding mode when the judgment result is yes.

For example, when the length 3 corresponding to the network names ABC and the length 3 corresponding to the network passwords 123 and 123 are encoded to obtain the target transmission data 3ABC3123, the first bit of the target transmission data is set as the length corresponding to the network name in the encoding mode; the second to the fourth bits are network names; the fifth bit is the length corresponding to the network password; the sixth to eighth bits are network ciphers. The target transmission data is divided into eight parts of 3, A, B, C, 3, 1, 2 and 3 according to a preset division mode. When the preset data embedding mode is as follows: embedding each sub-transmission data into the fourth byte of each preset multicast address, and embedding the number corresponding to each sub-transmission data into the third byte of each preset multicast address, wherein the obtained target multicast addresses are as follows: 225.115.1.3, 225.115.2.65, 225.115.3.66 and 225.115.4.67, 225.115.5.3, 225.115.6.1 and 225.115.7.2225.115.8.3.

Accordingly, the manner of extracting the sub-transmission data from each target multicast address at this time may specifically be: according to the conversion relationship between the MAC address and the IP address, the destination MAC address in the network data frame of the destination multicast address 225.115.1.3 is obtained: 01-00-5e-73-1-3, and acquiring data 1 corresponding to the 5 th byte of the MAC address, namely the serial number is 1; the data 3 corresponding to the 6 th byte, i.e., the sub transmission data, is 3. And according to the way of extracting the sub-transmission data, the corresponding sub-transmission data in each target address and the number corresponding to each sub-transmission data can be obtained, thereby obtaining the network name and the network password by decoding.

In addition, it can be understood that after the network name and the network password are obtained through decoding, the promiscuous mode is closed, so that the second terminal is prevented from receiving too many invalid data packets, and the load pressure of the second terminal for receiving the data packets is reduced.

obtaining a wireless network channel list;

accordingly, the receiving the plurality of target multicast addresses multicast by the transit terminal includes:

if not, the current channel is switched to the next channel recorded in the network channel list, and the step of judging whether any target multicast address is received in the current channel is continuously executed.

It is understood that, in this implementation manner, before receiving the plurality of target multicast addresses multicast by the relay terminal, the second terminal scans the wireless network channels existing in the environment where the second terminal is located in advance, and forms the wireless network channel list with the scanned wireless network channels.

For example, the wireless network channels scanned currently include channel 1, channel 6 and channel 13, so that the second terminal only switches on channel 1, channel 6 and channel 13, and when the channel 1, channel 6 and channel 13 are switched to any channel, the step of judging whether any target multicast address is received on the current channel is executed, so that the second terminal is prevented from waiting for data on non-existing channels (for example, channel 2 to channel 5), and the time for accessing the network is reduced.

judging whether the access to the wireless network by using the access network identification is successful, if so, broadcasting a message of successfully accessing the wireless network to the first terminal;

if not, the wireless network is not successfully accessed.

The first terminal may preset a feedback timeout time, for example, 5 seconds, and if the first terminal does not acquire the access information fed back by the second terminal within 5 seconds, it is prompted that the second terminal fails to access the wireless network.

It can be understood that, in this implementation manner, when the second terminal successfully accesses the wireless network, the second terminal feeds back successful information of accessing the wireless network to the first terminal in time, so as to prevent the first terminal from sending data to the transit terminal all the time in a circulating manner; when the second terminal is not successfully accessed to the wireless network, the first terminal receives the information prompting the failure of the second terminal to access the wireless network after the preset feedback overtime time, and the first access terminal is prevented from blindly waiting.

The method for accessing the network by the terminal according to the embodiment of the present invention is further described with reference to fig. 5.

As shown in fig. 5, fig. 5 includes a second terminal in a promiscuous mode, a first terminal having an input means, and a relay terminal, wherein a network name is input on a touch screen of the first terminal: hikwifi, network password: 123456, and others: ipcsn123, after the click determination is performed on the touch screen, the network name, the network password and other information may be encoded into target transmission data, the target transmission data is embedded into a plurality of preset multicast addresses according to a preset data embedding manner, a plurality of target multicast addresses to be transmitted are obtained, and the plurality of target multicast addresses are transmitted to the relay terminal through the wireless network shown in fig. 5; the transit terminal multicasts the plurality of target multicast addresses by using the wireless network; the second terminal starts the promiscuous mode, switches among the scanned channel 1, channel 6 and channel 13, when receiving the target multicast address in the channel 1, does not switch the channel any more, continues to receive other target multicast addresses in the channel 1, after receiving the target multicast addresses completely, restores the target multicast addresses to obtain target transmission data, and after decoding the target transmission data, obtains the network access name: hikwifi, network password: 123456, and others: ipcsn123 and access the wireless network generated by the transit terminal using the access network identifications.
