At present, the whole solution of the intelligent device has a big data analysis function, so that the intelligent device is required to be capable of accessing the internet and interacting with a background cloud.

At present, software development kits of many chip manufacturers integrate the function, and although specific communication details are inconsistent, the Soft AP (Access Point) mode, i.e., the mode of implementing wireless Access by using dedicated software, is selected by more and more intelligent devices by virtue of its high Access success rate and is provided to users as a preferred Access mode. However, the Soft AP method is not very versatile and cannot meet the application scenarios of all smart devices. Because the user terminal needs to be switched to the hotspot of the intelligent device from the hotspot of the wireless router in the whole Soft AP network access process and then switched to the hotspot of the wireless router, the problem that the IP address allocated by the user terminal from the wireless router for the second time is different from the IP address allocated for the first time exists.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, steps, and so forth. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more device modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The idea of realizing network access and binding the core thereof by the Soft AP mode is as follows: the intelligent device can be used as a hotspot, and after the user terminal is connected to the hotspot, the service identifier Set SSID (service Set identifier) and the password PWD (password) of the wireless router are sent to the intelligent device, so that the intelligent device can be connected to the wireless router. And after the hot spot of the intelligent equipment disappears, the user terminal is reconnected to the wireless router. At the moment, the user terminal, the intelligent equipment and the wireless router are in the same local area network.

As shown in fig. 1, the specific process is as follows: the user terminal is connected to the hotspot of the wireless router and records the SSID, the PWD and the allocated IP address; the user terminal exits the network where the wireless router is located, is connected to the intelligent device hotspot, and sends the SSID and PWD of the wireless router and the allocated IP address to the intelligent device; the intelligent device starts a Soft AP mode, namely a hot spot mode, creates an intelligent device hot spot, and receives an SSID (service set identifier), a PWD (public power device) of the wireless router and an IP (Internet protocol) address distributed by the user terminal, which are sent by the user terminal; switching from Soft AP mode to terminal mode STA (station) and connecting to the wireless router; the user terminal reconnects to the wireless router; the intelligent equipment interactively communicates with the user terminal according to the IP address received before, and sends the intelligent equipment information to the user terminal in a unicast mode; and the user terminal utilizes the intelligent equipment information to interact with the locally stored user information and the cloud.

At present, Software Development Kit (SDK) of many chip manufacturers integrates the function, but the Soft AP mode cannot meet the application scenarios of all intelligent devices. Because the user terminal needs to switch from the hotspot of the wireless router to the hotspot of the intelligent device and then to the hotspot of the wireless router in the network accessing process, the problem that the IP address allocated from the wireless router for the second time is different from the IP address allocated for the first time exists. There are currently three main solutions to this problem: the system comprises a multicast broadcast scheme, a chip dual-channel switching scheme and a cloud end large-cycle binding scheme.

a. Multicast broadcast scheme

The scheme is that the intelligent equipment information message sent by the intelligent equipment is multicast or broadcast, so that whether the IP address of the user terminal is changed or not does not need to be concerned. However, the scheme is influenced by a wireless router by a large number of factors, and due to the fact that the wireless router manufacturers in China have different qualifications, some wireless routers do not forward multicast or broadcast messages, and therefore the scheme cannot be suitable for some wireless routers.

b. Chip dual-channel switching scheme

The scheme depends on the strong capability of a Wi-Fi chip in the intelligent equipment, the chip can work in a Soft AP mode and an STA mode simultaneously, and can ensure high-frequency switching on two different channels through a special CPU scheduling mechanism, so that the requirement that the intelligent equipment can communicate with the user terminal when being connected to the wireless router can be met. At present, manufacturers capable of producing chips with the function are few, and the chips of the internet of things of other mainstream manufacturers cannot meet the two conditions. Therefore, the solution is not applicable to all smart devices, and obviously, the solution has high resource consumption and high cost.

c. Cloud large-cycle binding scheme

The scheme is that matching binding logic made by a user terminal is switched to cloud processing, namely after the intelligent device is connected to the wireless router, the intelligent device and the user terminal do not interact in a local area network, and the intelligent device and the user terminal report respective information to the cloud for binding processing. The scheme makes the cloud logic become more complex, and easily causes the chaos of the corresponding relation between the user terminal and the intelligent equipment when the N intelligent equipment simultaneously accesses the network and binds. Therefore, the scheme is not suitable for intelligent equipment products with large user bases.

The Soft AP mode network access scheme provided by the invention mainly utilizes an IP address detection mechanism in a Dynamic Host Configuration Protocol (DHCP). When a user terminal is connected to a wireless router for the first time, an IP address distributed by a DHCP Server for the user terminal and an MAC address of the terminal are stored in a DHCP. The scheme has the characteristics of no dependence on a wireless router, no dependence on a chip and wide application range.

As shown in fig. 2, the network access method for the smart device may be used in the smart device side, where the smart device is a device, an apparatus, or a machine with computing processing capability, and for example, may include a smart home appliance, a smart wearable product, a smart monitoring device, and the like, but the disclosure is not limited thereto. The method comprises steps S202 to S212:

in step S202, a hotspot mode is initiated.

After the intelligent device prepares for network access, a hotspot mode is started, and a device hotspot is created, namely the intelligent device is used as an access point for a user terminal to access.

In step S204, access point information and a first IP address and a MAC address of the user terminal are received.

The user terminal firstly establishes communication with the access point, acquires a service identifier set SSID and a password PWD of the access point, and is simultaneously allocated with a first IP address, and correspondingly, the allocated first IP address and the MAC address of the user terminal are recorded in a DHCP. The intelligent device receives a service identifier set SSID and a password PWD of the access point and a first IP address and an MAC address of the user terminal, which are sent by the user terminal, and after receiving the information, the intelligent device can be disguised as the user terminal to communicate with the access point.

In step S206, the hotspot mode is switched to the terminal mode.

And after the information sent by the user terminal is obtained, switching the hotspot mode into a terminal mode to prepare for communication with the access point.

In step S208, a request message of the DHCP protocol is constructed by using the first IP address and the MAC address of the user terminal, and the request message is sent to the access point.

And constructing a request message of a DHCP protocol by using the received first IP address and the MAC address of the user terminal, and sending the request message to the access point through a service identifier set SSID and a password PWD of the access point. Since the first IP address and MAC address of the user terminal are utilized at this time, the access point considers the smart device to be the user terminal. Thus, the smart device masquerades as a user terminal establishing communication with the access point.

In step S210, a second IP address of the user terminal is obtained according to the return result of the access point.

And after receiving the request message, the access point returns a result to the intelligent equipment, and the intelligent equipment acquires the second IP address by using the identity of the user terminal.

In step S212, communication is established with the user terminal through the second IP address of the user terminal.

After the user terminal is switched back to the hotspot of the access point from the hotspot of the intelligent device, the access point needs to be reconnected, and because the intelligent device is disguised that the user terminal acquires the second IP address before, the second IP address of the user terminal is recorded in a DHCP server of the access point, and the second IP address is distributed to the user terminal when the user terminal is accessed again. At this time, the user terminal and the smart device are both assigned the same second IP address, and the smart device can communicate with the user terminal through this second IP address.

The network access method for the intelligent equipment of the embodiment solves the problem that the IP address changes when the user terminal reconnects the access point by utilizing the characteristic of the DHCP protocol, greatly improves the network access success rate of the intelligent equipment, does not depend on hardware equipment such as a wireless router, a chip and the like, and has the characteristic of wide application range.

As shown in fig. 3, the network access method for a smart device, which may be used in a smart device, where a user terminal may be a mobile phone and an access point may be a wireless router, includes steps S302 to S326:

in step S302, a hotspot mode is initiated.

After the intelligent device prepares for network access, a hotspot mode is started, and a device hotspot is created, namely the intelligent device is used as an access point for a mobile phone to access.

In step S304, the wireless router information and the first IP address and the MAC address of the mobile phone are received.

The mobile phone firstly establishes communication with the wireless router, obtains a service identifier set SSID and a password PWD of the wireless router, and is simultaneously allocated with a first IP address, and correspondingly, the allocated first IP address of the mobile phone and the MAC address of the mobile phone are recorded in a DHCP release file of the DHCP server. The intelligent device receives the service identifier set SSID and the password PWD of the wireless router sent by the mobile phone and the first IP address and the MAC address of the mobile phone, and after receiving the information, the intelligent device can be disguised as the mobile phone to communicate with the wireless router.

In step S306, the hotspot mode is switched to the terminal mode.

And after the information sent by the mobile phone is obtained, switching the hotspot mode into a terminal mode to prepare for communication with the wireless router.

In step S308, the wireless router is connected according to the service identification set SSID and the password PWD.

And connecting to the wireless router by using the received service identification set SSID and the password PWD of the wireless router, wherein the wireless router considers that the intelligent device is a mobile phone because the first IP address and the MAC address of the mobile phone are used at the moment.

In step S310, a REQUEST (REQUEST) message of the DHCP protocol is constructed according to the first IP address and the MAC address of the mobile phone, and is sent to the wireless router.

And constructing a REQUEST (REQUEST) message of a DHCP protocol by using the first IP address and the MAC address of the mobile phone, and sending the REQUEST (REQUEST) message to the wireless router. Thus, the smart device masquerades as a handset to establish communication with the wireless router.

In step S312, the wireless network card of the smart device is set to enter the promiscuous listening mode.

The wireless network card capable of setting the intelligent equipment enters a hybrid monitoring mode, receives all data streams passing through the wireless network card, and adds a message filtering hook function to the bottom layer according to the MAC address of the mobile phone and the DHCP protocol port, so that messages returned by the DHCP server can be accurately captured. The above description is only provided for a method of obtaining a returned message, and this is not the point of the present invention, and those skilled in the art can think of obtaining a returned message by using other technical means, and the present disclosure is not limited thereto.

In step S314, the result returned by the wireless router is judged.

After receiving the REQUEST message, the wireless router returns a result to the intelligent device, and when returning an Acknowledgement (ACK) message, the wireless router means that the previous first IP address is still valid, so that it can be determined that the IP address allocated to the mobile phone has not changed, that is, the previous first IP address, and then the process goes to step S316.

When the wireless router returns a Negative Acknowledgement (NACK) message, which means that the previous first IP address has been allocated to another device or the lease of the IP address has come, it jumps to step S318.

In step S316, the first IP address is saved as an IP address for communication with the mobile phone.

The first IP address is saved as an IP address for communication with the mobile phone, so that communication is established with the mobile phone through the IP address, and then the process goes to step S324.

In step S318, a DHCP DISCOVER (DISCOVER) message is constructed and transmitted according to the MAC address of the mobile phone.

If the first IP address changes, the intelligent device needs to simulate the mobile phone to construct a DHCP Discovery (DISCOVER) message for network re-entry, can construct the DHCP Discovery (DISCOVER) message according to the MAC address of the mobile phone, and sends the Discovery (DISCOVER) message to the wireless router to request to obtain a new IP address.

In step S320, the OFFER (OFFER) packet returned by the wireless router is received, and the second IP address is resolved.

And receiving an OFFER (OFFER) message returned by the wireless router, and after receiving the OFFER (OFFER) message, resolving the newly allocated second IP address from the OFFER (OFFER) message. And at the moment, records of the second IP address and the mobile phone MAC address are already generated in a DHCP release file of the DHCP Server of the wireless router.

In step S322, the newly allocated second IP address is saved as the IP address for communication with the mobile phone. And saving the newly allocated second IP address as the IP address for communicating with the mobile phone, thereby replacing the first IP address sent by the mobile phone before.

In step S324, the promiscuous monitor mode of the wireless network card is turned off.

And after the IP address communicated with the mobile phone is obtained, the hybrid monitoring mode of the wireless network card can be closed.

In step S326, communication is established with the handset based on the IP address with which the handset is communicating.

And establishing communication with the mobile phone by utilizing the saved IP address for communicating with the mobile phone. After the mobile phone is switched back to the hotspot of the wireless router from the hotspot of the intelligent device, the mobile phone needs to be reconnected, and because the intelligent device is disguised as the mobile phone before to acquire the second IP address, the second IP address of the mobile phone is recorded in a DHCP server of the wireless router at the moment, and when the mobile phone is accessed again, the second IP address is allocated to the mobile phone. At this time, the mobile phone and the intelligent device are both assigned the same second IP address, and the intelligent device can communicate with the mobile phone through the second IP address.

According to an example embodiment, the smart device can send smart device information to the mobile phone, and the smart device performs data interaction with the cloud terminal through the mobile phone.

According to an exemplary embodiment, the prompt message is sent after the second IP address of the user terminal is acquired, that is, after a new IP address is acquired, a prompt message is sent, where the prompt message may be a light, a flash, a sound, or a music, and the like, as long as the prompt function is provided for prompting the user, and the present invention is not limited to the prompt manner.

According to the network access method for the intelligent equipment, the DHCP protocol is utilized, the intelligent equipment is disguised into the mobile phone through the intelligent equipment, the mobile phone and the wireless router are interacted to obtain the new IP address, the problem that the IP address changes when the user terminal reconnects the access point is solved, the network access success rate of the intelligent equipment is greatly improved, the method does not depend on hardware equipment such as the wireless router and a chip, and the method has the characteristic of wide application range.

As shown in fig. 4, the network access method for the smart device may be applied to a user terminal, where the user terminal may be an internet access terminal such as a mobile phone, a tablet computer, or a computer, and the disclosure is not limited thereto. The method comprises steps S402-S408:

in step S402, access point information and a first IP address are acquired.

And connecting to the access point, and recording the service identification set SSID, the password PWD and the allocated first IP address of the access point.

In step S404, the smart device is connected, and the access point information, the first IP address, and the MAC address are transmitted to the smart device.

The intelligent device is a hotspot, the user terminal is accessed into the intelligent device, and the service identifier set SSID and the password PWD of the access point which are obtained before, the allocated first IP address and the MAC address of the user terminal are sent to the intelligent device.

In step S406, the access point is connected and a second IP address is acquired.

And after the information is sent to the intelligent equipment, the access point is reconnected to obtain the IP address again, and the obtained second IP address may be the same as the previous first IP address or a newly allocated IP address.

In step S408, communication is established with the smart device through the second IP address.

Since the intelligent device is disguised that the user terminal acquires the second IP address before, the DHCP server of the access point records the second IP address of the user terminal, and thus the second IP address is allocated to the user terminal when the user terminal re-accesses. At this time, the user terminal and the smart device are both assigned the same second IP address, and the smart device can communicate with the user terminal through this second IP address.

According to an example embodiment, the access point may be reconnected and the second IP address may be acquired after a predetermined time, that is, the user terminal may be configured to reconnect the access point after a predetermined time, so as to ensure that the interaction between the smart device and the access point is completed, that is, the smart device has successfully acquired the second IP address. By adopting the mode, the success rate of network access can be further improved. The predetermined time may be 2 to 4 seconds.

According to an example embodiment, after the intelligent device finishes sending the prompt message after acquiring the second IP address, the user terminal may manually input an instruction to reconnect the access point, and after receiving the access instruction, the user terminal reconnects the access point and acquires the second IP address. By adopting the mode, the success rate of network access can be fully guaranteed.

According to an example embodiment, after the user terminal establishes communication with the intelligent device through the second IP address, the user terminal receives information of the intelligent device, and performs data interaction with the cloud terminal by using the information of the intelligent device and the locally stored user information.

According to the network access method for the intelligent equipment, the MAC address of the user terminal is provided for the intelligent equipment, so that the intelligent equipment can be disguised as the user terminal to interact with the access point, the problem that the IP address changes when the user terminal reconnects the access point is solved, the network access success rate of the intelligent equipment is greatly improved, the method does not depend on hardware equipment such as a wireless router and a chip, and the method has the characteristic of wide application range.

Fig. 5 shows a time chart of a network access method for the intelligent device based on fig. 3 and 4. As shown in fig. 5, the network accessing method for the smart device of the present invention is shown as a whole, and includes the interaction between the user terminal, the smart device and the access point, where the user terminal may be a mobile phone, and the access point may be a wireless router.

As shown in fig. 6, the network access apparatus for an intelligent device, which can be used at an intelligent device side, includes:

the starting module 602 is configured to start a hotspot mode.

After the intelligent device is ready for network access, the start module 602 starts a hotspot mode to create a device hotspot, that is, the intelligent device itself is used as an access point for a user terminal to access.

A receiving module 604, configured to receive the access point information and the first IP address and the MAC address of the user terminal.

The user terminal firstly establishes communication with the access point, acquires a service identifier set SSID and a password PWD of the access point, and is simultaneously allocated with a first IP address, and correspondingly, the allocated first IP address and the MAC address of the user terminal are recorded in a DHCP. The receiving module 604 receives the SSID and PWD of the ap and the first IP address and MAC address of the ue sent by the ue, and the smart device can pretend to be the ue to communicate with the ap after receiving the above information.

A switching module 606, configured to switch the hotspot mode to a terminal mode.

After obtaining the information sent by the user terminal, the switching module 606 switches the hotspot mode to the terminal mode to prepare for communication with the access point.

The request module 608 is configured to construct a request packet of a DHCP protocol by using the first IP address and the MAC address of the user terminal, and send the request packet to the access point.

The request module 608 constructs a request message of the DHCP protocol by using the received first IP address and MAC address of the user terminal, and sends the request message to the access point through the service identifier set SSID and the password PWD of the access point. Since the first IP address and MAC address of the user terminal are utilized at this time, the access point considers the smart device to be the user terminal. Thus, the smart device masquerades as a user terminal establishing communication with the access point.

The obtaining module 610 is configured to obtain the second IP address of the user equipment according to the return result of the access point.

After receiving the request message, the access point returns a result to the intelligent device, and the obtaining module 610 obtains the second IP address by using the identity of the user terminal.

A communication module 612, configured to establish communication with the user terminal through the second IP address of the user terminal.

After the user terminal is switched back to the hotspot of the access point from the hotspot of the intelligent device, the access point needs to be reconnected, and because the intelligent device is disguised that the user terminal acquires the second IP address before, the second IP address of the user terminal is recorded in a DHCP server of the access point, and the second IP address is distributed to the user terminal when the user terminal is accessed again. At this time, the user terminal and the smart device are both assigned the same second IP address, and the communication module 612 can communicate with the user terminal through the second IP address.

The network access device for the intelligent equipment of the embodiment solves the problem that the IP address changes when the user terminal reconnects the access point by utilizing the characteristic of the DHCP protocol, greatly improves the network access success rate of the intelligent equipment, does not depend on hardware equipment such as a wireless router and a chip, and has the characteristic of wide application range.

According to an exemplary embodiment, when the obtaining module 610 obtains an Acknowledgement (ACK) message returned by the wireless router, it means that the previous first IP address is still valid, and therefore it may be determined that the IP address of the user terminal has not changed, that is, the previous first IP address.

According to an exemplary embodiment, when the obtaining module 610 obtains a Negative Acknowledgement (NACK) message returned by the wireless router, which means that the previous first IP address has been allocated to another device or a lease of the IP address is reached, the intelligent device needs to simulate the user terminal to construct a DHCP Discovery (DISCOVER) message for network re-entry, construct a DHCP Discovery (DISCOVER) message according to the MAC address of the user terminal, send the Discovery (DISCOVER) message to the access point, and request to obtain a new IP address. The obtaining module 610 receives an OFFER (OFFER) message returned by the access point, and after receiving the OFFER (OFFER) message, resolves the newly allocated second IP address therefrom.

According to an exemplary embodiment, the present invention further includes a prompting module, configured to send a prompting message after acquiring the second IP address of the user terminal, that is, after acquiring the new IP address, send a prompting message, where the prompting message may be light, flash, sound, or music, and the prompting message is not limited in the prompting manner as long as the prompting function can be performed to prompt the user to pay attention.

As shown in fig. 7, the network access apparatus for the smart device may be used in a user terminal, where the user terminal may be an internet access terminal such as a mobile phone, a tablet computer, or a computer, and the disclosure is not limited thereto. The method comprises the following steps:

an obtaining module 702 is configured to obtain the access point information and the first IP address.

The obtaining module 702 connects to the access point and records the service identifier set SSID, the password PWD, and the assigned first IP address of the access point.

A sending module 704, configured to connect to the smart device, and send the access point information, the first IP address, and the MAC address to the smart device.

Since the smart device is a hotspot, the user terminal is accessed to the smart device, and the sending module 704 sends the service identifier set SSID and the password PWD of the access point, which are obtained before, and the allocated first IP address and the MAC address thereof to the smart device.

And an access module 706, configured to connect to the access point and obtain the second IP address.

After sending the information to the smart device, the access module 706 reconnects the access point to obtain the IP address again, where the obtained second IP address may be the same as the previous first IP address or may be a newly allocated IP address.

And a communication module 708, configured to establish communication with the intelligent device through the second IP address.

Since the intelligent device is disguised that the user terminal acquires the second IP address before, the DHCP server of the access point records the second IP address of the user terminal, and thus the second IP address is allocated to the user terminal when the user terminal re-accesses. At this point, both the user terminal and the smart device are assigned the same second IP address, and the communication module 708 can communicate with the user terminal through this second IP address.

According to an example embodiment, the access point may be reconnected and the second IP address may be obtained after a predetermined time, and the access module 706 may be configured to reconnect the access point to the user terminal after a predetermined time, so as to ensure that the interaction between the smart device and the access point is completed, that is, the smart device has successfully obtained the second IP address. By adopting the mode, the success rate of network access can be further improved. The predetermined time may be 2 to 4 seconds.

According to an example embodiment, after the intelligent device finishes sending the prompt message after acquiring the second IP address, the user terminal may manually input a reconnect instruction, and after receiving the access command, the access module 706 reconnects the access point and acquires the second IP address. By adopting the mode, the success rate of network access can be fully guaranteed.

The network access device for the intelligent equipment of the embodiment provides the MAC address of the user terminal for the intelligent equipment, so that the intelligent equipment can be disguised as the user terminal to interact with the access point, the problem that the IP address changes when the user terminal reconnects the access point is solved, the network access success rate of the intelligent equipment is greatly improved, the network access device does not depend on hardware equipment such as a wireless router and a chip, and the network access device has the characteristic of wide application range.
