[0045] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0046] Currently, after logging into a certain account on a device, you can quickly search for other devices nearby that have logged into the same account, so as to establish a connection with the device that has logged into the same account. However, for some public devices, there is no login account, such as personal computers (PCs), tablets (pads), televisions (TVs), etc. For these devices, it is impossible to search for devices with the same account, that is, it is impossible to achieve self-organizing networks.

[0047] In some embodiments, surrounding devices may be searched through Bluetooth low energy (BLE) broadcasting and BLE scanning, and a connection may be established based on this.

[0048] In some embodiments, after searching for a device, it is necessary to determine whether there is a trust relationship between the devices. For example, if a connection has been established between devices, the identification (ID) of the other device will be stored. When device A stores the ID of device B, it can be considered that there is a trust relationship between device A and device B.

[0049] However, in the above embodiment, if device A establishes a connection with device B, device B needs to wake up its application processor (AP), which results in high power consumption and does not fully utilize the low power consumption advantage of the Bluetooth chip. In addition, the processing flow is long and the efficiency is low.

[0050] In some embodiments, the device ID can be carried in the BLE broadcast, and a filtering condition can be set on the BLE scanning end, and the filtering condition includes the device ID. That is, the broadcast sent by device A to device B carries the ID of device B. When device B obtains the broadcast, it can determine whether to establish a connection with device A based on whether the broadcast contains the ID of device B.

[0051] However, in the above embodiment, since the content of BLE broadcast is limited, currently generally more than 20 bytes, it cannot carry too much data and can only carry the ID of a device, that is, it can only support one device to determine whether there is a trust relationship and establish a connection. If multiple BLE broadcasts are sent, power consumption will increase.

[0052] Therefore, the present disclosure provides a device connection method, which maps the connection data of the multiple second devices to be connected in response to a first device corresponding to multiple second devices to be connected, wherein the length of the mapped connection data is less than the total length of the connection data before mapping, and establishes a connection with the second device based on the mapped connection data, thereby being able to quickly establish a connection with a device with a trusted relationship and improving efficiency.

[0053] The device connection method in the present disclosure can be applied to terminals, TVs, etc. Among them, the terminal can also be called terminal equipment, mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (mobile phones), pocket personal computers (pocket personal computers, PPCs), handheld computers, personal digital assistants (personal digital assistants, PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle to everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0054] Figure 1 is a flow chart of a device connection method according to an exemplary embodiment. Figure 1 As shown, the device connection method can be applied to a first device, and includes the following steps.

[0055] In step S11, in response to the first device corresponding to a plurality of second devices to be connected, first connection data of the plurality of second devices are mapped into second connection data.

[0056] In one embodiment, when the first device corresponds to multiple second devices to be connected, the first connection data of the multiple second devices can be mapped to obtain the second connection data. Among them, the first connection data is data that can uniquely identify the second device, for example, it can be a device identification (device identification, device ID), it can be a media access control (media access control) address, and the MAC address can also be called a local area network address. Of course, the first connection data can also be other data that can uniquely identify the second device, and the present disclosure is not limited. The first device can correspond to multiple second devices to be connected, which can be understood as a connection established between the first device and multiple second devices, or it can be understood as the first device storing the first connection data of multiple second devices. Among them, there is a trust relationship between the devices that establish a connection. There may be a trust relationship between the devices that have established a connection, or there may not be a trust relationship. The trust relationship can be understood as a prerequisite for data transmission. In some cases, data transmission can be carried out between devices with a trust relationship, and data transmission cannot be carried out between devices without a trust relationship. Data transmission can only be carried out after a trust relationship is established.

[0057] In this embodiment, the length of the second connection data is less than the total length of the plurality of first connection data. For example, if the plurality of first connection data occupy A bits in total and the second connection data occupy B bits, then the length of the plurality of first connection data is less than the total length of the plurality of first connection data, that is, B is less than A.

[0058] In one embodiment, the length of the second connection data may be less than or equal to the length of the first connection data.

[0059] In step S12, based on the second connection data, a connection is established with the second device that has acquired the second connection data.

[0060] In one embodiment, the second connection data may be broadcasted, and a connection may be established with a second device that has acquired the second connection data. For example, the second connection data may be broadcasted via BLE. After the first device broadcasts the second connection data, any device may acquire the second connection data. Since the second connection data is obtained by mapping multiple first connection data, the second device may establish a connection with the first device only after acquiring the second connection data. That is, a connection may be quickly established with the second device to be connected from all devices.

[0061] The present disclosure maps the connection data of the multiple second devices to be connected in response to a first device corresponding to multiple second devices to be connected, wherein the length of the mapped connection data is less than the total length of the connection data before mapping, and establishes a connection with the second device based on the mapped connection data. It is possible to quickly establish a connection with a device having a trusted relationship without waking up an AP, thereby saving power consumption and improving efficiency.

[0062] In some embodiments, Figure 2 is a flow chart of a data mapping method according to an exemplary embodiment. Figure 2 As shown, the following steps are included.

[0063] In step S21, the first connection data is mapped N times, the mapping target is a preset mapping value set, and N mapping values ​​are obtained.

[0064] In one embodiment, the first connection data may be mapped N times, with the mapping target being a preset mapping value set, to obtain N mapping values. It can be understood that each mapping obtains a mapping value in the mapping value set. Different first connection data correspond to different N mapping values, where N is a positive integer.

[0065] In one embodiment, mapping the first connection data N times may be performed by using the first connection data as a random seed to generate N random numbers. The range of random numbers is a mapping value set, for example, the range of random numbers is 0-31, that is, the mapping value set includes 0, 1, 2, 3...29, 30, 31, a total of 32 values. Exemplarily, if the first connection data of device A is mapped twice, the mapping value obtained once is 7, and the mapping value obtained another time is 19, then the first connection data of device A corresponds to 2 mapping values, which are 7 and 19 respectively.

[0066] In step S22, second connection data is obtained based on N mapping values ​​respectively corresponding to the plurality of first connection data.

[0067] In one embodiment, N mapping values ​​corresponding to a plurality of first connection data may be used as the second connection data. That is, the second connection data includes the mapping value. For example, the second device to be connected includes device A, device B, and device C, the mapping value of device A is 7 and 19, the mapping value of device B is 1 and 18, and the mapping value of device C is 5 and 7, then the second connection data may be (1,5,7,18,19). In this embodiment, the length of the second connection data is not fixed. If device A obtains the second connection data, since the second connection data includes the mapping values ​​7 and 19 of device A, device A can determine that it has a trust relationship with the first device and establish a connection with the first device. If other devices obtain the second connection data, and the second connection data does not include its mapping value, then no connection is established with the first device, so as to quickly establish a connection with the second device with a trust relationship.

[0068] In one embodiment, N mapping values ​​corresponding to the plurality of first connection data may be hashed to second connection data of fixed length. The fixed length of the second connection data depends on the number of mapping values ​​in the mapping value set. For example, if the mapping value set includes 0, 1, 2, 3...29, 30, 31, a total of 32 values, the length of the second connection data may be 32 bits. Figure 3 is a schematic diagram of mapping according to an exemplary embodiment, such as Figure 3As shown, the length of the second connection data is 32 bits, and the mapping values ​​of device A are 7 and 19, that is, the first connection data of device A is hashed to the 8th bit and the 20th bit, and the 8th bit and the 20th bit of the second connection data are both set to 1. The mapping values ​​of device B are 1 and 18, that is, the first connection data of device A is hashed to the 2nd bit and the 19th bit, and the 2nd bit and the 19th bit of the second connection data are both set to 1. The mapping values ​​of device C are 5 and 7, that is, the first connection data of device A is hashed to the 6th bit and the 8th bit, and the 6th bit and the 8th bit of the second connection data are both set to 1. The second connection data is 32 bits of data, in which the 2nd, 6th, 8th, 19th, and 20th bits are set to 1.

[0069] The present disclosure maps the first connection data N times to obtain N mapping values, and obtains the second connection data based on the N mapping values, so as to quickly establish a connection with the second device having a trust relationship.

[0070] In some embodiments, the mapping value set in the present disclosure includes M mapping values, and M and N can be determined in the following manner: in response to the estimated number of second devices being a first preset number, M and N are determined from a first data pair set, the first data pair set includes multiple groups of M and N data pairs, and the error probability of each group of data pairs is less than a first threshold, and the error probability represents the probability that different first connection data correspond to the same mapping value.

[0071] In one embodiment, the estimated number of second devices can be understood as the number of second devices that may appear within a certain range. The estimated number of second devices can be set according to actual conditions. When the estimated number of second devices is the first preset number, M and N can be determined from the first data pair set. The first data pair set includes multiple groups of M and N data pairs. And each group of data corresponds to an error probability. The error probability refers to the probability that different first connection data correspond to the same mapping value. For example, different first connection data are mapped N times, and the mapping target is a mapping value set of M mapping values. If the N mapping values ​​obtained are the same, it means that an error occurs. The probability of an error is the error probability. The error probability of each group of data pairs in the first data pair set is less than the first threshold. That is, when the estimated number of second devices is the first preset number, M and N are determined based on the data pairs in the first data pair set, which can ensure that the mapping error probability is less than the first threshold.

[0072] In one embodiment, M and N are determined from the first data pair set, for example, by selecting any data pair. Alternatively, the data pair with the smallest error probability may be selected. Alternatively, the data pair with the smallest M value may be screened out from the first data pair set, and M and N may be determined from the data pair with the smallest M value. For example, if there is one data pair with the smallest M value, then M and N are determined to be the M and N of the data pair. If there are multiple data pairs with the smallest M value, one data pair may be selected from them, and M and N may be determined based on the selected data pair.

[0073] In one embodiment, the first preset number may be, for example, 4 or 5. The first data pair set may refer to Table 1, which shows the estimated number of second devices and their corresponding data pairs.

[0074] Table 1

[0075]

[0076] For example, when the estimated number of second devices is 4, the first data pair set may include (32, 3), (32, 4), (32, 5)···(32, 7), (40, 2), (40, 3), (40, 4)···(40, 8), (44, 2), (44, 3), (44, 4)···(44, 8). Taking (32, 3) as an example, it means that M is 32, N is 3, and the error probability corresponding to the data pair is 0.0166. When the estimated number of second devices is 5, the first data pair set may include (40, 3), (40, 4)···(40, 7), (44, 3), (44, 4)···(44, 8). In this embodiment, the first threshold value is 2%. Of course, the first preset number, the first data pair set, and the first threshold value shown in Table 1 of this embodiment are only illustrative examples and can be set according to actual conditions. The present disclosure does not limit them.

[0077] The present disclosure determines M and N from the first data pair set based on the estimated number of second devices as the first preset number, thereby ensuring that the error probability is less than a threshold for the possible number of second devices, thereby better avoiding the occurrence of connection errors.

[0078] In some embodiments, the mapping value set in the present disclosure includes M mapping values, and M and N can be determined in the following manner: in response to the estimated number of the second device being a second preset number, the second preset number representing the maximum estimated number whose error probability is less than a second threshold, M and N are determined from a second data pair set, the second data pair set including multiple groups of M and N data pairs, and the error probability of each group of data pairs is less than the second threshold, and the error probability represents the probability that different first connection data correspond to the same mapping value.

[0079] In one embodiment, when the estimated number of second devices is the second preset number, M and N can be determined from the second data pair set. The second preset number represents the maximum estimated number whose error probability is less than the second threshold. The error probability of multiple groups of M and N data pairs in the second data pair is less than the second threshold. The relationship between the second threshold and the maximum estimated number can be understood as follows: when the number of second devices exceeds the maximum estimated number, no matter how many M and N are, their error probability will exceed the second threshold. That is, only by mapping the first connection data of the second preset number of second devices at most can the error probability be controlled within the second threshold. The second threshold is greater than the first threshold. Of course, in some cases, the second threshold may also be equal to the first threshold, which is not limited in the present disclosure.

[0080] In one embodiment, the second preset number may be, for example, 9. The second data pair may refer to Table 2, which shows the estimated number of second devices and their corresponding data pairs.

[0081] Table 2

[0082]

[0083]

[0084] For example, when the estimated number of second devices is 9, the first data pair set may include (40, 3), that is, M is 40, N is 3, and the error probability corresponding to the data pair is 0.0974. In this embodiment, the first threshold is 10%. Of course, the second preset number, the second data pair set, and the second threshold shown in Table 2 of this embodiment are only illustrative examples and can be set according to actual conditions, and the present disclosure does not limit them.

[0085] The present disclosure maps the first connection data of as many second devices as possible in response to the estimated number of second devices being a second preset number, i.e., when the error probability is not greater than a second threshold, thereby establishing connections with more second devices when sending the second connection data once, which is more efficient.

[0086] In some embodiments, Figure 4 FIG. 1 is a flow chart of a method for determining M and N according to an exemplary embodiment. Figure 4 As shown, M and N can be determined as follows:

[0087] In step S31, a data pair with the smallest M value is determined from the second data pair set.

[0088] In step S32, M and N are determined based on the data pair.

[0089] In one embodiment, a data pair with the smallest M value can be selected from the second data pair set. M and N are determined based on the selected data pair. For example, if the selected data pair with the smallest M value is 1, M and N are determined based on the data pair. For example, the data pair is (M1, N1), and M1 represents the smallest M value. Then M can be determined to be M1 and N to be N1. If there are multiple data pairs with the smallest M value selected, one data pair can be selected from them to determine M and N. Or M and N can be determined based on the data pair with the smallest error probability. For example, the data pairs with the smallest M value are (M1, N1) and (M1, N2), and M1 is the smallest M value. A data pair with the smallest error probability can be determined from (M1, N1) and (M1, N2). For example, if the error probability of (M1, N1) is smaller, M is determined to be M1 and N is determined to be N1. If the error probability of (M1, N2) is smaller, M is determined to be M1 and N is determined to be N2.

[0090] The present disclosure determines M and N by determining the minimum value of M from the data pair set, so as to achieve a higher mapping efficiency when the error probability is less than the second threshold. Furthermore, if the second connection data is of fixed length, the smaller the M value is, the smaller the fixed length of the second connection data is, which can save the space occupied by the data.

[0091] In some embodiments, based on the second connection data, an incorrect connection may occur when establishing a connection with the second device. For example, assuming that the mapping values ​​of device A are 7 and 19, the mapping values ​​of device B are 1 and 18, and the mapping values ​​of device C are 5 and 7, then the second connection data includes 1, 5, 7, 18, and 19. When device D obtains the second connection data, assuming that the mapping values ​​of device D are 18 and 19, it is obvious that device D is not one of device A, device B, and device C, that is, device D may not be the second device to be connected to the first device, but device D can also find its own mapping value from the second connection data, thereby erroneously establishing a connection with the first device. In order to avoid incorrect connections, the present disclosure provides a device connection method, Figure 5 FIG. 1 is a flow chart of a device connection method according to an exemplary embodiment. Figure 5 As shown, the following steps are included.

[0092] In step S41, in response to the first device corresponding to a plurality of second devices to be connected, first connection data of the plurality of second devices are mapped into second connection data.

[0093] In step S42, based on the second connection data and the third connection data corresponding to the first device, a connection is established with the second device that has acquired the second connection data and the third connection data.

[0094] The implementation of step S41 in this embodiment may refer to the implementation of step S11 above, which will not be described in detail here.

[0095] In one embodiment, the first device may broadcast the second connection data and the third connection data at the same time, and the second connection data is used for any device that obtains the second connection data. When the second connection data does not contain its mapping value, it can be directly determined not to establish a connection with it. The third connection data is the connection data corresponding to the first device, and the third connection data is used to uniquely identify the first device. For example, it can be the device ID of the first device, or the MAC address of the first device, which is not limited in the present disclosure. The third connection data is used for any device that obtains the second connection data, and when the second connection data contains its mapping value, it is further determined based on the third connection data whether there is a trust relationship, so as to establish a connection. That is, it can be understood that other devices obtain the second connection data and the third connection data, and can determine whether the second connection data contains its own mapping value. If it does, the AP is woken up to further determine whether to establish a connection. If it does not, the second device does not need to wake up the AP and directly does not establish a connection.

[0096] Based on the same concept, the embodiment of the present disclosure also provides a device connection method, which can be applied to a second device. Figure 6 is a flow chart of a device connection method according to an exemplary embodiment. Figure 6 As shown, the device connection method includes the following steps.

[0097] In step S51, the second connection data broadcast by the first device is obtained.

[0098] In one embodiment, the second device may obtain the second connection data broadcast by the first device. The second connection data is obtained by mapping multiple first connection data, and the length of the second connection data is less than the total length of the multiple first connection data. The specific implementation method can refer to the implementation method in steps S11-S12 of the above embodiment, and the present disclosure will not be repeated here.

[0099] In step S52, in response to the second connection data corresponding to the second device, a connection is established with the first device.

[0100] In one embodiment, the second device may establish a connection with the first device broadcasting the second connection data based on whether the second connection data corresponds to the second device. If the second connection data corresponds to the second device, the second device may not establish a connection with the first device broadcasting the second connection data if the second connection data does not correspond to the second device. For example, if the second connection data includes the first connection data corresponding to the second device, it is determined that the second connection data corresponds to the second device.

[0101] The present disclosure obtains the second connection data through the second device to determine whether to establish a connection with the first device. Since the second connection data is obtained based on the mapping of the first connection data, it is possible to quickly establish a connection with a device with a trust relationship, and the efficiency is improved. For the second device, there is no need to wake up the AP, saving power consumption.

[0102] In some embodiments, Figure 7 is a flow chart of a device connection method according to an exemplary embodiment. Figure 7 As shown, the device connection method includes the following steps.

[0103] In step S61, the first connection data corresponding to the second device is mapped N times, and the mapping target is a preset mapping value set to obtain N mapping values.

[0104] In one embodiment, the first connection data of the second device may be mapped N times, and the mapping target is a preset mapping value set to obtain N mapping values ​​corresponding to the second device. The second device may record the N mapping values. The specific mapping method may refer to the above embodiment, and the present disclosure will not be repeated here.

[0105] In step S62, in response to the second connection data including N mapping values ​​corresponding to the second device, a connection is established with the first device that broadcasts the second connection data.

[0106] In one embodiment, if the second device determines from the acquired second connection data that it contains N mapping values ​​corresponding to the second device, it can be determined that there is a trust relationship between the second device and the first device broadcasting the second connection data, and a connection can be established with the first device broadcasting the second connection data.

[0107] In the present disclosure, by mapping the first connection data corresponding to the second device and comparing it with the mapping value included in the second connection data, if the second connection data includes the mapping value corresponding to the second device, a connection can be quickly established with the first device. There is no need to wake up the AP, and the connection is quickly established, while also saving power consumption.

[0108] In some embodiments, the mapping value set in the present disclosure includes M mapping values, and M and N can be determined in the following manner: in response to the estimated number of second devices being a first preset number, M and N are determined from a first data pair set, the first data pair set includes multiple groups of M and N data pairs, and the error probability of each group of data pairs is less than a first threshold, and the error probability represents the probability that different first connection data correspond to the same mapping value.

[0109] In some embodiments, the mapping value set in the present disclosure includes M mapping values, and M and N can be determined in the following manner: in response to the estimated number of the second device being a second preset number, the second preset number representing the maximum estimated number whose error probability is less than a second threshold, M and N are determined from a second data pair set, the second data pair set including multiple groups of M and N data pairs, and the error probability of each group of data pairs is less than the second threshold, and the error probability represents the probability that different first connection data correspond to the same mapping value.

[0110] In some embodiments, Figure 8 FIG. 1 is a flow chart of a method for determining M and N according to an exemplary embodiment. Figure 8 As shown, M and N can be determined as follows:

[0111] In step S71, a data pair with the smallest M value is determined from the second data pair set.

[0112] In step S72, M and N are determined based on the data pair.

[0113] The method for determining M and N in this embodiment can refer to the above embodiment and will not be repeated here.

[0114] In some embodiments, Fig. 9 is a flow chart of a device connection method according to an exemplary embodiment. Fig. 9 As shown, the device connection method includes the following steps.

[0115] In step S81, the second connection data broadcast by the first device is obtained.

[0116] In step S82, third connection data corresponding to the first device is obtained.

[0117] In step S83, in response to the second connection data corresponding to the second device and the third connection data having an association relationship with the second device, a connection is established with the first device.

[0118] In one embodiment, the second device may obtain the second connection data and the third connection data broadcast by the first device. When the second connection data corresponds to the second device. For example, when the second connection data includes a mapping value corresponding to the second device, it can be further judged according to the third connection data. The second device may wake up the AP and determine whether the second device has a trust relationship with the first device, that is, whether the second device has an association relationship with the third connection data, based on the third connection data corresponding to the first device. For example, the third connection data of the first device is stored in the second device. Alternatively, the third connection data of the first device is recorded in the historical connection record of the second device, etc.

[0119] In one embodiment, if the second connection data does not include a mapping value corresponding to the second device, it can be directly determined not to establish a connection with the first device without waking up the AP again.

[0120] By acquiring the third connection data, the present disclosure can further determine whether there is a trust relationship between the first device and the second device based on determining that the second connection data corresponds to the second device, so as to avoid the situation where an erroneous connection is established. If the second connection data does not correspond to the second device, it can be directly determined that the connection is established with the first device, that is, there is no need to wake up the AP every time, thereby saving power consumption.

[0121] In some embodiments, the data broadcast by the first device may include a bit for indicating whether the second connection data is included, and when the bit is 1, it indicates that the second connection data is included, and when the bit is 0, it may indicate that the second connection data is not included.

[0122] In some embodiments, the data broadcast by the first device may include a bit indicating whether the third connection data of the first device is included. When the bit is 1, it indicates that the third connection data is included. When the bit is 0, it may indicate that the third connection data is not included. If the third connection data is not included, the second device does not need to wake up the AP to save power consumption.

[0123] In some embodiments, the data broadcast by the first device may include a bit indicating whether to support establishing a device connection, that is, whether to support an ad hoc network.
