Description

Switching method and switching device of address information

Technical Field

The present application belongs to the technical field of wireless networks, and in particular, to a method, a device, an access point device, and a computer-readable storage medium for switching address information.

Background

A Wireless Local Area Network (WLAN) is a data transmission system, which uses Radio Frequency (RF) technology to replace a wireless network formed by twisted pair copper wires.

Wi-Fi (Wireless-Fidelity), among others, is a technology that allows electronic devices to connect to Wireless local area networks, typically using 2.4G or 5G radio frequency bands. Due to the different advantages and disadvantages of 2.4G or 5G, the dual WIFI technology is developed. The double-WiFi network acceleration technology utilizes a single device to be accessed to simultaneously connect two WiFi signals, and the two WiFi signals independently receive and transmit data, so that the network speed is greatly improved.

However, two wireless modules supporting the "dual WIFI technology" in the device to be accessed need to use different MAC addresses (physical addresses) and IP addresses (internet protocol addresses). If two radios use the same IP address, an IP address conflict may arise. Most software programs in the terminal equipment often do not support sharing of multiple IP addresses, so that the terminal equipment cannot apply the double-WIFI technology.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In a conventional wireless network technology, a 2.4G or 5G frequency band is often used as a radio frequency band for wireless communication. While 2.4G or 5G have different advantages: the frequency of the 5G frequency band is higher, the attenuation is larger when the frequency band propagates in the air or an obstacle, and the coverage distance is generally smaller than that of the 2.4G frequency band. The 2.4G frequency band has a narrow bandwidth, and the wireless environment is crowded and has large interference.

In order to take different advantages of 2.4G or 5G radio frequency bands into consideration, the double WIFI technology is developed. In the 'double-WIFI technology', the access point equipment simultaneously sends out signals of a 2.4G frequency band and a 5G frequency band so as to form two access point networks. The terminal equipment is respectively connected with the two access point networks through the two wireless modules, so that a double-WIFI function is realized. The wireless module in the terminal device needs to adopt different source IP addresses (source IP addresses) and different MAC addresses (physical addresses, also called hardware addresses), so that the dual WIFI function can be realized. However, most software programs in the terminal device often do not support multiple IP addresses to be shared, so that the terminal device cannot apply the "dual WIFI technology". To better explain the above technical problem, please refer to fig. 1, in which fig. 1 shows a schematic diagram of address information of a conventional wireless module provided in the present application. As shown in fig. 1, a conventional wireless module performs wireless communication using different source IP addresses and different MAC addresses, which includes the following steps: the terminal device 11 is connected to the access point device 12 and the access point device 13 through two wireless modules, respectively. The source IP address of the first radio module is: 192.168.1.20, the source MAC address is: 00-01-6C-06-A6-29, the source IP address of the second radio module is: 192.168.1.10, the source MAC address is: 00-01-6C-06-A6-26. After the access point device 12 and the access point device 13 receive the two data frames sent by the terminal device 11 through the addresses, the two data frames are forwarded to the gateway 14, and the gateway 14 forwards the two data frames to the ethernet 15.

If the wireless terminal cannot adopt multiple IP addresses, IP address collision is likely to occur, and wireless communication cannot be performed. Referring to fig. 2, fig. 2 is a schematic diagram illustrating address information of a conventional wireless module provided in the present application. As shown in fig. 2, if the conventional wireless module uses the same source IP address and different MAC addresses for wireless communication, IP address collision is easily caused, which is specifically as follows: the terminal device 11 is connected to the access point device 12 and the access point device 13 through two wireless modules, respectively. The source IP address of the first radio module is: 192.168.1.10, the source MAC address is: 00-01-6C-06-A6-29. The source IP address of the second radio module is: 192.168.1.10, the source MAC address is: 00-01-6C-06-A6-26. After the access point device 12 and the access point device 13 receive the two data frames sent by the terminal device 11 through the addresses, the two data frames are forwarded to the gateway 14. Gateway 14 detects that the two data frames have different source MAC addresses but the source IP is the same, creating a collision and no data communication is possible.

Therefore, most terminal devices cannot apply the dual WIFI technology for the above reasons.

In view of the above, embodiments of the present application provide a method, a device, an access point device, and a computer-readable storage medium for switching address information, which may solve the above technical problems.

First, the present application provides a wireless network system including a terminal device, a first access point device, and a second access point device.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a wireless network system provided in the present application. As shown in fig. 3, the wireless network system includes a terminal device 11, a first access point device 12, a second access point device 13, a gateway 14, and an ethernet 15. The number of the terminal devices 11, the number of the wireless modules in the terminal devices 11, the number of the access point devices, and the number of the access point networks formed by the access point devices may be more, which is not limited herein.

It should be emphasized that the number, location, address information and connection relationship of the devices in fig. 1, 2 and 3 are only exemplary and not limiting. Here, the terminal device 11 may connect only two access point networks corresponding to the first access point device 12 or the second access point device 13.

The terminal device 11 is configured to connect the first access point device 12 and the second access point device 13 through the first wireless module and the second wireless module. And transmits the data frame, the destination source address information, and the first source address information corresponding to each of the plurality of wireless modules in the terminal device 11 to the first access point device 12 and the second access point device 13 through the first wireless module and the second wireless module. Among them, the terminal device 11 includes a plurality of wireless modules for realizing wireless communication. The wireless module can be physical hardware (for example, a wireless network card) or virtual software (multiple virtual terminal devices are virtualized through software). In order to better explain the technical solution of the present application, the present application explains the technical solution of the present application by taking the terminal device 11 as an example that includes a first wireless module and a second wireless module. It is understood that the number of wireless modules in the terminal device 11 may be more, and is not limited herein.

The first access point device 12 is adapted to implement the steps of the method according to any of claims 1 to 7.

The second access point device 13 is adapted to implement the steps of the method according to any of claims 1 to 7.

In order to better explain the technical solution of the present application, after the present application integrally explains the process of three-terminal interaction (a terminal device, an access point device set, and a gateway form the three terminals), the present application further explains the execution steps of the access point device in detail. Referring to fig. 4, fig. 4 shows a schematic flow chart of three-terminal interaction provided by the present application.

As shown in fig. 4, the three-end interaction flow includes two stages: an uplink phase and a downlink phase.

(1) An uplink stage: the terminal device 11 transmits the target source address information and the first source address information to the first access point device 12 and the second access point device 13 through the two wireless modules, respectively. The first access point device 12 and the second access point device 13 receive the target source address information and the first source address information sent by the terminal device 11. The terminal device 11 sends uplink data frames to the first access point device 12 and the second access point device 13 through the two wireless modules, respectively. After receiving the uplink data frame, the first access point device 12 and the second access point device 13 modify the uplink source address information of the uplink data frame into the target source address information, respectively, obtain two first data frames with the same address information, and send the first data frames to the gateway 14, thereby completing the data communication in the uplink phase.

(2) A downlink stage: the gateway 14 transmits the downlink data frames to the first access point device 12 and the second access point device 13, respectively. After receiving the downlink data frame, the first access point device 12 and the second access point device 13 modify the destination address information in the downlink data frame into the first source address information (different wireless modules correspond to different first source address information), obtain the second data frame, and send the second data frame to the wireless module corresponding to the first source address information, thereby completing the data communication in the downlink stage.

Therefore, the method unifies different source address information in the uplink stage, and distributes the same destination address information in the downlink stage, so that the technical problem of IP address conflict is solved.

In the above general explanation, the embodiment takes the hardware environment shown in fig. 3 as an example, and details the execution flow of the access point device. Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a method for switching address information provided by the present application. The handover method is executed by an access point device (access point device 12 or access point device 13), and as shown in fig. 5, the handover method may include the following steps:

step 501, obtaining target source address information and first source address information corresponding to each of a plurality of wireless modules in a terminal device.

The source address information in this embodiment includes, but is not limited to, a combination of one or more kinds of address information, such as a source MAC address and source IP address information.

The destination address information includes, but is not limited to, second source address information of the terminal device, preset third source address information, or random source address information.

If the target address information is preset third source address information, the prestored third source address information and first source address information corresponding to each of the plurality of wireless modules in the terminal device are directly extracted from a storage module of the access point device.

If the target address information is random source address information, acquiring an unused source address information set, and randomly selecting one source address information from the source address information set as the target address information. And acquires the first source address information corresponding to each of the plurality of wireless modules in the terminal device 11 or a local storage module.

If the target address information is the second source address information of the terminal equipment, executing the following steps:

as an alternative embodiment of the present application, step 501 includes steps 5011 to 5012 as follows. Referring to fig. 6, fig. 6 shows a specific schematic flowchart of step 501 in a method for switching address information provided by the present application.

Step 5011, receiving a request frame sent by the terminal device; the request frame is used for accessing a wireless network.

Step 5012, extracting the target source address information and the first source address information corresponding to each of the plurality of radio modules in the terminal device from the request frame.

When the terminal device 11 accesses the access point device, the access point device needs to interact with the terminal device 11 through the management frame, so that the terminal device 11 accesses the access point device. Therefore, in the present application, the target source address information and the first source address information are transmitted through the request frame sent by the terminal device 11 in the interactive process (a traditional access process is adopted, and no additional process step needs to be added), and the specific process is as follows:

the access point device transmits a Beacon frame (Beacon frame). After receiving the Beacon frame, the terminal device 11 transmits a Probe Request frame (Probe Request frame) to the access point device. After receiving the Probe Request frame, the access point device transmits a Probe Response frame (Probe Response frame) to the terminal device 11. After receiving the Probe Response frame, the terminal device 11 performs identity authentication with the access point device. After the identity authentication is passed, the terminal apparatus 11 transmits an Association Request frame (Association Request frame) to the access point apparatus. After receiving the Association Request frame, the ap device sends an Association Response frame (Association Response frame) to the ue 11 to complete an access procedure.

As can be seen from the above process, the Request frame sent by the terminal device 11 to the access point device includes a Probe Request frame, an Association Request frame, and the like. The access point device may extract the target source address information and the first source address information in the request frame.

Preferably, there may be a case that authentication fails or the like in the access procedure. If the authentication fails, the access point device cannot obtain the Association Request frame, and thus cannot obtain the target source address information and the first source address information. Regardless of whether the authentication is successful or failed, the ap device may obtain the Probe Request frame in the scanning stage, so that the Probe Request frame may be preferentially selected as the Request frame for transmitting the destination source address information and the first source address information, so as to prevent the destination source address information and the first source address information from being unavailable.

Step 502, receiving an uplink data frame sent by the terminal device through the plurality of wireless modules.

In order to better explain the technical solution of the present application, the present application explains the technical solution of the present embodiment by taking the terminal device 11 as an example including a first wireless module and a second wireless module.

The terminal device 11 sends an uplink data frame to the access point device through the first wireless module and the second wireless module. The source address information corresponding to each uplink data frame may be completely different, partially different, or completely the same. The access point device uplinks the data frame and performs step 503.

Step 503, modifying the uplink source address information in each uplink data frame into the target source address information to obtain a first data frame; the first data frame is for transmission to a destination device.

In order to avoid the IP address collision, the access point device uniformly modifies the uplink source address information in each uplink data frame into the target source address information to obtain the first data frame.

The target source address information is partially or completely different from the plurality of first source address information, and when the target source address information is completely different from the plurality of first source address information, the corresponding embodiment is as follows:

as an optional embodiment of the present application, when the first source address information is MAC address information (that is, the first source address information of the first wireless module is first MAC address information, the first source address information of the second wireless module is second MAC address information, and the destination source address information is destination MAC address information), step 503 executes the step: modifying the first MAC address information or the second MAC address information in each uplink data frame into the target MAC address information; and the IP address in each uplink data frame is the same.

Exemplarily, as shown in fig. 3, the first MAC address information of the uplink data frame sent by the first radio module is: 00-01-6C-06-A6-29, and the second MAC address information of the uplink data frame sent by the second wireless module is: 00-01-6C-06-A6-26. The source IP addresses of the two uplink data frames are both: 192.168.1.10. the destination MAC address information is: 00-01-6C-06-A6-30. After the first access point device 12 receives the uplink data frame, the first MAC address information (00-01-6C-06-A6-29) in the uplink data frame is modified to: 00-01-6C-06-A6-30, and obtaining first data. After the second access point device 13 receives the uplink data frame, the second MAC address information (00-01-6C-06-A6-26) in the uplink data frame is modified to: 00-01-6C-06-A6-30, and obtaining a first data frame.

After obtaining the first data frame, the first ap device 12 and the second ap device 13 respectively send the first data frame to the target terminal (i.e. the gateway 14), and at this time, from the perspective of the gateway 14, the first data frame may be regarded as a data frame (MAC address information is completely the same) sent by the same wireless module or device, so that the problem of IP address collision is solved.

The target source address information is partially or completely different from the plurality of first source address information, and when the target source address information is partially the same as the plurality of first source address information, the corresponding embodiment is as follows:

as an alternative embodiment of the present application, when the first MAC address information is the same as the target MAC address information, step 503 includes the following steps 5031 to 5032. Referring to fig. 7, fig. 7 is a specific schematic flowchart illustrating step 503 in a method for switching address information according to the present application.

Step 5031, using the first MAC address information in the first uplink data frame sent by the first wireless module as the target MAC address information.

Since the first MAC address information is the same as the target MAC address information, the first MAC address information is directly used as the target MAC address information without modifying the first MAC address information, that is, the conventional wireless communication process is performed.

Step 5032, modifying the second MAC address information in the second uplink data frame sent by the second wireless module into the target MAC address information.

Since the second MAC address information is different from the target MAC address information, the second MAC address information needs to be modified to the target MAC address information so that the MAC address information to the first data frame is the same. Thereby realizing normal wireless communication.

It is understood that, when the second MAC address information is the same as the destination MAC address information and the first MAC address information is different from the destination MAC address information, the performing step can be obtained by analogy with step 5031 and step 5032, and details are not described herein.

It can be understood that, when the first source address information is the MAC address information and the number of the first source address information is greater than two, the execution steps can be obtained by analogy with step 5031 and step 5032, and details are not repeated here.

As an optional embodiment of the present application, when the source address information is MAC address information and a source IP address, the source IP address in the uplink data frame may be different. The implementation process is as follows:

illustratively, the first MAC address information and the first IP address of the uplink data frame sent by the first radio module are: 00-01-6C-06-A6-29, 192.168.1.11. The second MAC address information and the second P address of the uplink data frame sent by the second wireless module are: 00-01-6C-06-A6-29, 192.168.1.12. After the first access point device 12 receives the uplink data frame, the first MAC address information (00-01-6C-06-A6-29, 192.168.1.11) in the uplink data frame is modified to 00-01-6C-06-A6-30, 192.168.1.10, so as to obtain a first data frame. After the second access point device 13 receives the uplink data frame, the fifth source IP address (00-01-6C-06-A6-29, 192.168.1.12) in the uplink data frame is modified to 00-01-6C-06-A6-30, 192.168.1.10, so as to obtain the first data frame.

It is understood that, when the first source address information is other types of address information, the execution flow of step 503 is the same as that in the above-mentioned alternative embodiment, and is not described herein again. A person skilled in the art may obtain the execution steps corresponding to other types of address information by analogy with the execution steps of any one of the above alternative embodiments.

In this embodiment, after receiving an uplink data frame sent by a terminal device, the uplink source address information of each uplink data frame is modified uniformly, so as to obtain a first data frame with the same target source address information. Because each first data frame has the same target source address information, the first data frames are data frames sent by the same wireless module in the view angle of the target equipment, and the problem of IP address conflict is further avoided. Therefore, data communication can be carried out no matter whether each wireless module adopts the same IP address or not, so that the terminal equipment can apply the double-WIFI technology.

Optionally, on the basis of the embodiment shown in fig. 5, after step 501, the following step is further included, please refer to fig. 8, and fig. 8 shows a schematic flowchart of another address information switching method provided in this application.

Step 801, receiving a downlink data frame sent by the destination device.

Step 802, using the first source address information as destination address information of the downlink data frame to obtain a second data frame; the second data frame is for transmission to the wireless module.

After receiving the downlink data frame from the destination device (i.e., the gateway 14), the access point device needs to perform split transmission on the downlink data frame (i.e., transmit the downlink data frame to the first wireless module or the second wireless module). The first wireless module or the second wireless module have different address information, so that the access point device needs to use the first source address information as the destination address information of the downlink data frame.

As an optional embodiment of the present application, when the first source address information is MAC address information (that is, the first source address information of the first wireless module is first MAC address information, the first source address information of the second wireless module is second MAC address information, and the destination address information is destination MAC address information), step 802 executes the step: and using the first MAC address information or the second MAC address information as the destination MAC address information of the downlink data frame to obtain a second data frame.

Illustratively, as shown in fig. 3, the gateway 14 sends the same downlink data frame to the first access point device 12 and the second access point device 13, where the destination IP address of the downlink data frame is: 192.168.1.10, the destination physical address is: 00-01-6C-06-A6-30. After receiving the downlink data frame, the first access point device 12 obtains a second data frame by using the first MAC address information (00-01-6C-06-A6-29) as destination MAC address information of the downlink data frame, and sends the second data frame to the first wireless module. After receiving the downlink data frame, the second access point device 13 obtains a second data frame by using the second MAC address information (00-01-6C-06-A6-26) as destination MAC address information of the downlink data frame, and sends the second data frame to the second wireless module. The source IP addresses of the first wireless module and the second wireless module are both: 192.168.1.10 (same as the destination IP address of the downstream data frame), so the destination IP address of the downstream data frame does not need to be modified.

When the first wireless module and the second wireless module are both connected to the same access point device, the access point device needs to select a target wireless module from the plurality of wireless modules to transmit the first data frame. This implementation provides several options as follows:

mode (1): and selecting the wireless module corresponding to the maximum signal intensity as a target wireless module according to the signal intensity of the access point network connected with each wireless module.

Mode (2): and selecting the wireless module corresponding to the minimum delay as a target wireless module according to the delay of the access point network connected with each wireless module.

Mode (3): one wireless module is randomly selected from the plurality of wireless modules as a target wireless module.

Mode (4): as an alternative embodiment of the present application, step 802 includes steps 8021 to 8023 as follows. Referring to fig. 9, fig. 9 is a specific schematic flowchart illustrating step 802 in a method for switching address information according to the present application.

Step 8021, obtain a first transmission rate of the first wireless module and a second transmission rate of the second wireless module.

Step 8022, if the first transmission rate is greater than the second transmission rate, using the first MAC address information as destination MAC address information of the downlink data frame to obtain a third data frame; the third data frame is for transmission to a first wireless module.

Step 8023, if the first transmission rate is not greater than the second transmission rate, using the second MAC address information as destination MAC address information of the downlink data frame to obtain a fourth data frame; the fourth data frame is for transmission to a second radio module.

As an alternative embodiment of the present application, when the first wireless module and the second wireless module are connected to different access point devices, the gateway 14 is required to select a target wireless module, and the selection manner can be similar to the manner (1) to the manner (4). And after the target wireless module is selected, transmitting the downlink data frame to the access point equipment connected with the target wireless module. And the access point equipment modifies the destination address information of the downlink data frame according to the address information of the target wireless module to obtain a second data frame, and transmits the second data frame to the target wireless module.

As an optional embodiment of the present application, when the first MAC address information is the same as the destination MAC address information, the first access point device 12 directly sends the downlink data frame to the first wireless module. The second access point device 13 obtains a second data frame by using the second MAC address information as destination MAC address information of the downlink data frame, and sends the second data frame to the second wireless module.

It can be understood that, when the second MAC address information is the same as the destination MAC address information and the first MAC address information is different from the destination MAC address information, the steps performed can be similar to the above steps, and are not described herein again.

As an optional embodiment of the present application, when the first source address information is MAC address information and a source IP address, the following procedure is executed:

illustratively, the gateway 14 sends the same downlink data frame to the first access point device 12 and the second access point device 13, where the destination IP address of the downlink data frame is: 192.168.1.10, the destination physical address is: 00-01-6C-06-A6-30. After receiving the downlink data frame, the first access point device 12 obtains a second data frame by using the first MAC address information (00-01-6C-06-A6-29) and the fourth source IP address (192.168.1.11) as destination address information of the downlink data frame, and sends the second data frame to the first wireless module. After receiving the downlink data frame, the second access point device 13 obtains a second data frame by using the second MAC address information (00-01-6C-06-A6-26) and the fifth source IP address (192.168.1.12) as destination address information of the downlink data frame, and sends the second data frame to the second wireless module.

It is understood that, when the source address information is other types of address information, the execution flow of step 802 is the same as the two alternative embodiments described above, and is not described herein again. A person skilled in the art may obtain the execution steps corresponding to other types of address information by analogy with the execution steps of any one of the above alternative embodiments.

In this embodiment, after receiving a downlink data frame sent by a target terminal, first source address information corresponding to different wireless modules is used as destination address information of the downlink data frame to obtain a second data frame, so that the second data frame is transmitted to the wireless module corresponding to the first source address information, so that the different wireless modules perform data communication, and a "dual WIFI technology" is implemented.

Referring to fig. 10, the present application provides an address information switching apparatus 10, which is a first access point device, please refer to fig. 10, fig. 10 shows a schematic diagram of an address information switching apparatus provided in the present application, and the address information switching apparatus shown in fig. 10 includes:

an obtaining unit 101, configured to obtain target source address information and first source address information corresponding to each of a plurality of wireless modules in a terminal device;

a receiving unit 102, configured to receive an uplink data frame sent by the terminal device through a plurality of the wireless modules;

a modifying unit 103, configured to modify uplink source address information in each uplink data frame into the target source address information, so as to obtain a first data frame; the first data frame is for transmission to a destination device.

According to the address information switching device, after the uplink data frames sent by the terminal equipment are received, the uplink source address information of each uplink data frame is modified in a unified mode, and the first data frames with the same target source address information are obtained. Because each first data frame has the same target source address information, the first data frames are data frames sent by the same wireless module in the view angle of the target equipment, and the problem of IP address conflict is further avoided. Therefore, data communication can be carried out no matter whether each wireless module adopts the same IP address or not, so that the terminal equipment can apply the double-WIFI technology.
