Wireless communication pairing method and system thereof

technical field

The present invention relates to the technical field of wireless communication, in particular to a high-security wireless communication pairing method and system thereof.

Background technique

With the rapid development of technology, various wireless mice, wireless keyboards, wireless drawing tablets, wireless microphones and other devices have been widely used in daily life. Compared with wired devices, wireless devices use electromagnetic wave signals for transmission. Therefore, in addition to reducing the consumption cost of cables (connecting wires), they also have the advantages of reduced storage space and high operating distance. In recent years, wireless devices have gradually replaced wired devices.

Most of the current pairing technologies between wireless devices use wireless methods to transmit pairing information. For example, a wireless mouse will send a wireless signal to a wireless network transceiver module (Universal Serial Bus Dongle) equipped with a Universal Serial Bus to request a wireless pairing procedure. However, since the wireless signal is transmitted in the form of broadcast, it is easy for those interested in obtaining relevant pairing information by skimming or simulating the pairing data, and then using the pairing information to steal or destroy data. Therefore, the issue of security is indeed a risk encountered in the use of current wireless devices.

In addition to security issues, since wireless devices communicate with wireless signals of a specific frequency (for example, using a signal with a center frequency of 2.4G Hz for communication), when multiple wireless devices are used at the same time, wireless channels are prone to occur. The problem of being occupied. When the wireless channel is occupied, the wireless signal will be interfered, and in severe cases, the device cannot operate normally.

FIG. 1 is a structure diagram of an embodiment of a wireless communication pairing system 100 . The wireless communication pairing system 100 includes a host device 10 , a signal receiver 11 and a signal transmitter 12 . The host device 10 can be any device with a software execution function or a programmable logic operation function, such as a computer, a workstation, a smart phone, and the like. The signal receiver 11 includes a first wired connection terminal 14 , a first storage device 15 and a first wireless connection terminal 16 . The signal receiver 11 can be a wireless network transceiver module (such as a USB Dongle) equipped with a Universal Serial Bus (USB). Therefore, the first wired connection 14 can be a USB connection. And the wired connection end of the present invention is not limited by the form of the universal serial bus connection end, any cable connection end, miniature universal serial bus (Micro-USB) connection end, network cable joint socket (RJ45) connection end, Mini Universal Serial Bus (Mini-USB) connectors and the like all belong to the category disclosed by the present invention. The first storage device 15 can be any memory device capable of reading and writing, such as a hard disk, a non-volatile memory (Non-volatile Memory), and the like. The first wireless connection terminal 16 can be a signal receiving terminal with network transmission function, and the supported signal type can be any form of electromagnetic wave signal. In this embodiment, the first wireless connection terminal 16 can be used to receive electromagnetic wave signals with a frequency of 2.4 GHz. The signal transmitter 12 can be any device capable of transmitting signals, such as a wireless mouse, a wireless keyboard, or a wireless digital drawing tablet and so on. The signal transmitter 12 includes a second wired connection terminal 17 , a second storage device 18 and a second wireless connection terminal 19 . The second wired connection terminal 17 can be a universal serial bus connection terminal, and can also be transformed into a combination of various wired connection terminals as the above-mentioned first wired connection terminal 14 . The second storage device 18 can be any memory device capable of reading and writing, such as a hard disk, a non-volatile memory, and the like. Similarly, the second wireless connection terminal 19 can be a signal sending terminal with a network transmission function, and the supported signal type can be any form of electromagnetic wave signal. In this embodiment, the second wireless connection terminal 19 can be used to send electromagnetic wave signals with a frequency of 2.4 GHz. In the wireless communication pairing system 100 , the host device 10 is coupled to the first wired connection end 14 of the signal receiver 11 and the second wired connection end 17 of the signal transmitter 12 . In other words, the host device is respectively coupled to the signal receiver 11 and the signal transmitter 12 in a wired connection. Also, the host device 10 may include an operation interface 13 . After the signal receiver 11 and the signal transmitter 12 establish two wired connections with the host device 10, the host device 10 pairs the signal receiver 11 and the signal transmitter 12 so that the first wireless connection terminal 16 and the second wireless connection terminal 17 wireless communication is enabled. The way for the host device 10 to pair the signal receiver 11 and the signal transmitter 12 can be automatically paired by software/app, or the user can use the operation interface 13 to input self-defined pairing parameters to perform the pairing manually. In the wireless communication pairing system 100 , since the wireless communication parameters carried by the signal receiver 11 and the signal transmitter 12 during pairing are input to the host device 10 through wired transmission, no wireless signal is broadcast. Therefore, the wireless communication pairing system 100 can greatly reduce the probability of wireless communication parameters being stolen. The method for wireless communication pairing performed by the wireless communication pairing system 100 will be described below.

FIG. 2 is a flow chart of the wireless communication pairing system 100 performing wireless communication pairing. The process of wireless communication pairing includes step S201 to step S211. However, the wireless communication pairing process of the present invention is not limited to the sequence of steps S201 to S211. For example, the sequence of steps S201 and S202 can be interchanged, and the sequence of steps S204 and S205 can also be interchanged. Any reasonable step transformation and addition/omission of steps fall within the scope of the present invention. Step S201 to step S211 are described as follows:

Step S201: Connect the signal receiver 11 to the host device 10 through the first wired connection terminal 14;

Step S202: Connect the signal transmitter 12 to the host device 10 through the second wired connection terminal 17;

Step S203: Can the host device 10 detect the signal receiver 11 and the signal transmitter 12? If yes, enter step S204; if no, return to step S201;

Step S204: Identify at least one first wireless communication parameter of the signal receiver 11;

Step S205: identifying at least one second wireless communication parameter of the signal transmitter 12;

Step S206: compare at least one first wireless communication parameter with at least one second wireless communication parameter, if they are consistent, go to step S211; if not, go to step S207;

Step S207: The host device 10 starts the pairing procedure and informs the user;

Step S208: Generate at least one paired wireless communication parameter corresponding to the user setting;

Step S209: storing at least one paired wireless communication parameter in the signal receiver 11 and the signal transmitter 12;

Step S210: pairing is completed.

Step S211: Does the user request to start the pairing program to modify the pairing parameters? If yes, go to step S207; if not, go to step S210 to complete pairing.

In step S201 , the signal receiver 11 is connected to the host device 10 through the first wired connection terminal 14 . For example, the user connects the signal receiver 11 (USB Dongle) to the host device 10 through the USB port. Next, in step S202 , the signal transmitter 12 is connected to the host device 10 through the second wired connection terminal 17 . For example, the user connects the wireless mouse to the host device 10 through the USB port. Herein, the signal receiver 11 and the signal transmitter 12 of the present invention have the function of dual mode transmission (Dual Modes Transmission). That is, both the signal receiver 11 and the signal transmitter 12 have the function of transmitting data with the host device 10 through the wired connection terminal, and also have the function of transmitting data through their respective wireless connection terminals. After the user connects the signal receiver 11 and the signal transmitter 12 to the host device 10 in a wired manner, according to step S203, the software or application program in the host device 10 will detect the signal receiver 11 and the signal transmitter 12 , to determine whether the signal receiver 11 and the signal transmitter 12 are connected to the host device 10 reliably. If the signal receiver 11 and the signal transmitter 12 cannot be detected (that is, cannot be identified), it means that the function of the wired connection end of the signal receiver 11 and the signal transmitter 12 is malfunctioning (possibly due to poor contact, rust or damage). Therefore, according to steps S201 to S202, the user will connect the signal receiver 11 and the signal transmitter 12 to the host device 10 again. However, steps S201 to S203 can also be modified reasonably. For example, when the host device 10 detects the signal receiver 11 but not the signal transmitter 12 , the user only needs to connect the signal transmitter 12 to the host device 10 again according to step S202 . Alternatively, when the host device 10 detects the signal transmitter 12 but not the signal receiver 11 , the user only needs to connect the signal receiver 11 to the host device 10 again according to step S201 . After both the signal receiver 11 and the signal transmitter 12 are detected by the host device 10, according to steps S204 and S205, the host device 10 will identify at least one wireless communication parameter of the signal receiver 11 and the signal transmitter 12 respectively. To avoid confusion, the wireless communication parameter of the signal receiver 11 is referred to as the first wireless communication parameter, and the wireless communication parameter of the signal transmitter 12 is referred to as the second wireless communication parameter. The first wireless communication parameter and the second wireless communication parameter may be a radio frequency identification (Radio Frequency Identification) parameter, a link key (Link Key), an advanced encryption standard key (Advanced Encryption Standard Key), a serial number or a wireless channel parameter and the like. After the host device 10 reads at least one wireless communication parameter corresponding to the signal receiver 11 and at least one second wireless communication parameter corresponding to the signal transmitter 12, according to step S206, the host device 10 will send at least one first The wireless communication parameter is compared with at least one second wireless communication parameter. If at least one first wireless communication parameter and at least one second wireless communication parameter are inconsistent, it means that the signal receiver 11 and the signal transmitter 12 are not in a paired communication system, then according to step S207, the host device 10 will start the pairing procedure, and inform the user. Conversely, if all the first wireless communication parameters and the second wireless communication parameters are consistent, it means that the signal receiver 11 and the signal transmitter 12 are in a paired communication system. Then, according to step S211, the host device 10 will confirm whether the user Request to start pairing procedure to modify pairing parameters? If yes, go to step S207; if not, go to step S210 to complete the pairing. In other words, in the wireless communication pairing process, there are two conditions for entering step S207 to start the pairing procedure. The first type is that when the original communication parameters of the signal receiver 11 and the signal transmitter 12 are inconsistent, a pairing procedure will be entered. The second type is that the original communication parameters of the signal receiver 11 and the signal transmitter 12 are consistent, but when the user requests to start the pairing program to modify the pairing parameters, the pairing program will be entered. However, in the second case (step S211), if the user does not request to start the pairing procedure, the wireless communication pairing process will enter step S210 and end. When the wireless communication pairing process enters the pairing start procedure of step S207, according to step S208, the host device 10 will generate at least one paired wireless communication parameter corresponding to the user setting. However, as mentioned above, the host device 10 can also use the application program to start the pairing procedure, so at least one wireless communication parameter after pairing can also be automatically generated by using the application program. The paired wireless communication parameters may be paired radio frequency identification parameters, link key, AES key, serial number or wireless channel parameters and so on. Subsequently, according to step S209, the host device 10 will store at least one paired wireless communication parameter in the first storage device 15 of the signal receiver 11 and the second storage device 18 of the signal transmitter 12, and complete the pairing according to step S210 . Therefore, after the pairing is completed, since the paired wireless communication parameters have been stored in the signal receiver 11 and the signal transmitter 12, the user can directly start the wireless communication function of the signal receiver 11 and the signal transmitter 12 to carry out Wireless data transmission. Moreover, in steps S201 to S211, due to the step of the host device 10 detecting the signal receiver 11 and the signal transmitter 12, the step of the host device 10 identifying at least one first wireless communication parameter and at least one second wireless communication parameter, the host device The step of generating at least one paired wireless communication parameter corresponding to the user setting by the device 10 is completed through wired data transmission without broadcasting any wireless signal. Therefore, the wireless communication pairing system 100 can greatly reduce the probability of wireless communication parameters being stolen.

FIG. 3 is a flow chart of channel setting performed by the wireless communication pairing system 100 . FIG. 4 is a schematic diagram of selecting a selected wireless channel from multiple available wireless channels in the process of channel setting. Herein, the wireless communication pairing process of the present invention may only include steps S201 to S211 shown in FIG. 2 , which has the technical effect of greatly reducing the probability of wireless communication parameters being stolen. However, in order to optimize the wireless channel setting between the signal receiver 11 and the signal transmitter 12 . The invention also discloses the flow of channel setting. In other words, the flow of channel setting in FIG. 3 may be a subsequent step after step S210. Therefore, after executing the pairing process in FIG. 2 and the channel setting process in FIG. 3 , the risk of the wireless communication parameters of the signal receiver 11 and the signal transmitter 12 being stolen can not only be greatly reduced, but also the signal receiver 11 and the signal transmitter 12 The channel settings between can also be optimized, thus improving the quality of wireless communication. The flow of channel setting includes step S301 to step S306. However, any reasonable step transformation and addition/omission of steps fall within the scope of the present invention. Step S301 to step S306 are described as follows:

Step S301: Identify the information of multiple available wireless channels between the signal receiver 11 and the signal transmitter 12;

Step S302: Detect whether at least one available wireless channel among the multiple available wireless channels is interfered? If yes, enter step S303; if no, enter step S306;

Step S303: the host device 10 starts the channel setting program and informs the user;

Step S304: the user selects at least one selected wireless channel from a plurality of available wireless channels through the host device 10;

Step S305: The channel setting is completed.

Step S306: Does the user request to activate the channel setting program to set the transmission channel? If yes, go to step S303; if not, go to step S305 to complete channel setting.

In step S301 , the host device 10 identifies information of multiple available wireless channels (Available Wireless Channels) between the signal receiver 11 and the signal transmitter 12 . For example, as shown in FIG. 4, the host device 10 will identify a plurality of wireless channels CH1 to CH4 originally preset between the signal receiver 11 and the signal transmitter 12, wherein the frequency band corresponding to the wireless channel CH1 is B1, wireless The frequency band range corresponding to the channel CH2 is B2, the frequency band range corresponding to the wireless channel CH3 is B3, and the frequency band range corresponding to the wireless channel CH4 is B4. Due to the wireless communication environment, channel gain (Channel Gain) attenuation will occur in certain frequency spectrums, such as shadow effect (Shadow Effect) or signal interference in the same frequency band. Therefore, for multiple wireless channels CH1 to CH4, the received signal strength indicator (Received Signal Strength Indicator, RSSI) information corresponding to each channel will also be different. Next, in step S302, the host device 10 detects whether at least one of the available wireless channels is interfered (Channel Interference). The basis for detecting channel interference can be the aforementioned RSSI information, the signal-to-noise ratio (SNR) of the training signal (Pilot Signals), or any algorithm for judging whether the channel gain of the wireless channel is fading. For example, in FIG. 4 , the wireless channel CH4 has a large interference, which leads to a serious attenuation of the channel gain and a serious decrease of the RSSI. At this time, according to step S303, the host device 10 will start the channel setting program and notify the user. On the contrary, if the multiple wireless channels are not disturbed, then according to step S306, the host device 10 will ask the user whether to request to start the channel setting program to change the transmission channel? If yes, go to step S303; if not, go to step S305 and complete channel setting. In other words, there are two conditions for entering the channel setting program of step S303. The first type is that at least one of the available wireless channels is interfered, and the host device 10 will start a channel setting procedure. The second type is that multiple available wireless channels are not interfered, but when the user requests to start the channel setting program, the host device 10 will also start the channel setting program. Afterwards, according to step S304 , the user selects at least one selected wireless channel from a plurality of available wireless channels through the host device 10 . For example, as shown in FIG. 4 , the user can select a wireless channel CH2 with the least interference from a plurality of available wireless channels CH1 to CH4. However, step S304 can also be reasonably changed to any step that avoids using the interfered wireless channel. For example, in step S304, if multiple available wireless channels are severely interfered, the user can set a new wireless channel CH5 (as shown in FIG. 4 ) and set its corresponding frequency band range B5. Then, the user can select the new wireless channel CH5 as the signal spectrum range for wireless transmission. When the user selects at least one selected wireless channel according to step S304, at least one selected wireless channel will be applied to the wireless transmission between the signal receiver 11 and the signal transmitter 12, and the channel is ended according to step S305 Set the program. Therefore, after performing steps S301 to S306, the signal receiver 11 and the signal transmitter 12 will not use the corresponding frequency band of the seriously interfered wireless channel for signal transmission. Even when all preset wireless channels are severely interfered, users can still customize the signal transmission frequency band to avoid severe distortion of received signal strength. In other words, the channel setting procedure from step S301 to step S306 ensures the wireless signal transmission quality between the signal receiver 11 and the signal transmitter 12, so that the operation between the signal receiver 11 and the signal transmitter 12 has better high reliability.

In the wireless communication pairing system 100 of the present invention, in addition to using the host device 10 to pair the signal receiver 11 and the signal transmitter 12 for wireless communication, in other embodiments, the signal receiver 11 and the signal transmitter 12 can also realize self- pairing function. For example, the signal transmitter 12 may retain a storage slot. When the signal receiver 11 (USB Dongle) is placed in the storage slot of the signal transmitter 12, as long as the power is turned on, the signal transmitter 12 and the signal receiver 11 can be connected with the built-in wired connection terminal to complete the wireless communication. pair.

In summary, the present invention describes a wireless communication pairing method and system thereof. Both the signal receiver and the signal transmitter are connected to the host device through a wired connection terminal. The software/application on the host device will obtain and compare the pairing data related to the signal receiver and the signal transmitter. If they are the same, it means that the signal receiver and the signal transmitter have been paired. Unless the user requests to modify the pairing parameters, otherwise No additional processing will be done. If not, the software/application program will actively ask the user whether to perform synchronization and pairing, and also provide an operation interface for the user to customize the pairing parameters, or process according to the default pairing parameters suggested by the system. Since all the pairing steps are completed by data communication through wired transmission without broadcasting any wireless signal, the host device is only regarded as a data transmission medium during the pairing process. Therefore, the wireless communication pairing system of the present invention can greatly reduce the probability of wireless communication parameters being stolen. Moreover, in order to reduce the possibility of wireless communication being interfered, the wireless communication pairing method of the present invention may further perform the step of channel setting. The software/application program on the host device will obtain information about the interference of currently available wireless channels, and if it finds that some predetermined channels are interfered and the device cannot be used normally, it will actively notify the user to select a suitable channel for signal transmission. Users can directly select the channel suitable for signal transmission through the software/app, or change the channel used for wireless transmission according to the channel suggested by the system. Therefore, the operation between the signal receiver and the signal transmitter will have higher reliability.
