The wireless communication mode includes but is not limited to bluetooth, ultrasonic wave, infrared ray, NFC, Wi-Fi and other wireless communication modes. The first terminal 10 and the second terminal 20 may be various types of smart terminals, for example, terminals having a plurality of wireless communication modules, such as a smart phone, a tablet computer, a wearable Device, a computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like.

In one embodiment, the first terminal 10 may establish a first connection with the second terminal 20, and after the first connection is established, the first terminal 10 and the second terminal 20 may perform negotiation of data transmission modes, so that at least one second connection may be established according to the determined data transmission mode. And, data transmission can be performed based on the determined data transmission manner.

Wherein, the first terminal 10 can establish a direct communication connection with the second terminal 20. The direct communication connection refers to direct communication between the first terminal 10 and the second terminal 20 without the aid of a third party device, as shown in fig. 1. The manner of establishing the direct communication connection between the first terminal 10 and the second terminal 20 may include: the first terminal 10 and the second terminal 20 establish a first connection based on the first data transmission mode, and may exchange connection information of the second data transmission mode over the first connection. The first terminal 10 and the second terminal 20 can establish a second connection based on a second data transmission mode based on the connection information. The energy consumption value of the first connection during data interaction is smaller than the energy consumption value of the second connection during data interaction, or the energy consumption value of the first connection during data interaction is smaller than the energy consumption value of the first terminal 10 and the second terminal 20 during interaction of the connection information of the second data transmission mode.

The first connection established by the first data transmission mode includes, but is not limited to, a bluetooth connection, a radio frequency connection, such as a Near Field Communication (NFC) connection, an ultrasonic connection, and an electromagnetic wave connection, such as an infrared connection. The second connection established by the second data transmission mode includes, but is not limited to, a Wi-Fi connection.

A second connection based on the Wi-Fi hotspot may be established between the first terminal 10 and the second terminal 20 based on the connection information. The first terminal 10 may actively start the Wi-Fi hotspot function of the first terminal 20 after establishing the first connection, so as to establish a second connection with the second terminal 20, or may trigger the second terminal 20 to start the Wi-Fi hotspot function through the first connection, so that the first terminal 101 accesses the second terminal 102 to complete establishment of the second connection.

In one embodiment, when a user of the first terminal 10 needs to transmit data to the second terminal 102, a direct communication button for managing a transmission mode (the transmission mode corresponds to at least one data transmission mode) on the first terminal 10 may be configured on the first terminal 10, and after the direct communication mode of the first terminal 10 is started by clicking the button, the first terminal 10 may automatically start a first transmission function corresponding to bluetooth and a second transmission function corresponding to Wi-Fi. Similarly, the user of the second terminal 20 may also start the direct communication button of the second terminal 20, and automatically start the first transmission function corresponding to the bluetooth and the second transmission function corresponding to the Wi-Fi. Then, the user of the first terminal 10 can determine the second terminal 20 from at least one terminal scanned by the first terminal 10 through bluetooth, and the first terminal 10 establishes the bluetooth connection with the second terminal 20.

Therefore, the embodiment of the invention can interact the connection information for establishing the Wi-Fi connection (i.e. the second connection) through the Bluetooth connection (i.e. the first connection), the connection information can be, for example, a user name and an access password of the terminal which is used as a Wi-Fi hotspot, and then the Wi-Fi connection (i.e. the second connection) is established according to the connection information, so that the energy consumption of the terminal is saved to a certain extent, the Wi-Fi connection (i.e. the second connection) can ensure a faster transmission speed, and meanwhile, the transmission efficiency of the terminal in data transmission is improved.

In an embodiment, when a second connection needs to be established, a Wi-Fi hotspot may be opened in the first terminal 10, and the user name and the password of the Wi-Fi hotspot are carried in a two-dimensional code manner, and the second terminal 20 may scan the two-dimensional code, so as to directly obtain the user name and the password of the Wi-Fi hotspot of the first terminal 10, and access to the first terminal 10 to establish a second connection between the two terminals. Or the second terminal 20 opens the Wi-Fi hotspot and carries the user name and the password of the Wi-Fi hotspot in a two-dimensional code manner, and the first terminal 10 may scan the two-dimensional code, and then directly obtain the user name and the password of the Wi-Fi hotspot of the second terminal 20, and access the second terminal 20 to establish a second connection between the two.

After the first terminal 10 and the second terminal 20 establish the first connection, the first performance information of the first terminal 10 and the second performance information of the second terminal 20 may be combined to determine a data transmission manner between the first terminal 10 and the second terminal 20. After determining the data transmission mode, the first terminal 10 may establish at least one second connection with the second terminal 20 based on the data transmission mode, and perform data interaction. The data transmission mode among the terminals is determined through the performance information of the terminals, so that the data transmission among the terminals is not limited to the data transmission mode corresponding to the first connection, the data transmission mode is expanded to a certain extent based on the performance information of the terminals, and the selectivity of the data transmission mode is improved.

In one embodiment, the first terminal 10 may include a plurality of wireless communication modules, and the second terminal 20 may also include a plurality of wireless communication modules, so that at least one connection is established between the first terminal 10 and the second terminal 20. Further, data may be exchanged over the established at least one connection.

In addition, the second performance information may further include parameters for determining an operating frequency band of a plurality of wireless communication modules included in the second terminal 20, including but not limited to a second terminal identifier, identifiers of the plurality of wireless transmission modules, or a value of the operating frequency band preset for the wireless communication module.

In an embodiment, the determining, by the first terminal 10, a data transmission manner between the first terminal 10 and the second terminal 20 by combining the first performance information of the first terminal 10 and the second performance information of the second terminal 20 may include: the first terminal 10 may determine a data transmission manner between the first terminal 10 and the second terminal 20 according to the transmission capability level determined by the first performance information and the transmission capability level determined by the second performance information. The determined data transmission mode may include a plurality of modes.

In one embodiment, the first capability information may include a maximum data transmission speed supported by a plurality of wireless communication modules included in the first terminal 10, and the second capability information may include a maximum data transmission speed supported by a plurality of wireless communication modules included in the second terminal. The first terminal 10 may rank the maximum data transmission speeds supported by the plurality of wireless communication modules included in the first performance information, such as from high to low, with the highest rank of the transmission capability ranked first. Also, the first terminal 10 may rank the maximum data transmission speeds supported by the plurality of wireless communication modules included in the second capability information, such as from high to low, with the highest transmission capability ranking first. The first terminal 10 may perform a plurality of data transmission manner combinations based on the transmission capability level determined by the first performance information and the transmission capability level determined by the second performance information to determine the data transmission manner between the first terminal 10 and the second terminal 20. The aim of optimizing the transmission rate can be achieved by combining strategies of a plurality of data transmission modes.

In one embodiment, the determining, by the first terminal 10, a data transmission manner between the first terminal 10 and the second terminal 20 by combining the first performance information of the first terminal 10 and the second performance information of the second terminal 20 may include: according to the information such as the size and the type of the transmission data, a data transmission mode suitable for large data transmission, small data transmission or data transmission in different formats is selected by combining the transmission capability of each wireless communication module of the first terminal 10 and the transmission capability of each wireless communication module of the second terminal 20. If the transmission data is smaller, using a data transmission mode corresponding to the wireless communication module with large data transmission or using a data transmission mode corresponding to the wireless communication module with small data transmission; the transmission data is large, and a data transmission mode corresponding to a wireless communication module for large data transmission, or a data transmission mode corresponding to a wireless communication module for small data transmission and a data transmission mode corresponding to a wireless communication module for large data transmission can be used. Wherein the transmission capability may be determined by a parameter included in the first performance information.

In one embodiment, the determining, by the first terminal 10, the data transmission mode between the first terminal 10 and the second terminal 20 by combining the performance information of the first terminal 10 and the performance information of the second terminal 20 may include: the first terminal 10 determines a data transmission mode between the first terminal 10 and the second terminal 20 according to the operating frequency band determined by the first performance information and the operating frequency band determined by the second performance information.

In one embodiment, when the first performance information includes parameters for determining an operating frequency band of each wireless communication module included in the first terminal 10, the first terminal 10 may determine the operating frequency band of each wireless communication module included in the first terminal 10 according to the first performance information. When the second performance information includes parameters for determining the operating frequency bands of the wireless communication modules included in the second terminal 20, the second terminal 20 may determine the operating frequency bands of the wireless communication modules included in the second terminal 20 according to the second performance information. The first terminal 10 may determine the data transmission mode between the first terminal 10 and the second terminal 20 according to the operating frequency band of each wireless communication module included in the first terminal 10 and the operating frequency band of each wireless communication module included in the second terminal 20.

The data transmission mode is determined by comparing and analyzing the operating frequency bands of the wireless communication modules included in the first terminal 10 and the operating frequency bands of the wireless communication modules included in the second terminal 20. Alternatively, when the difference between the operating frequency band of each wireless communication module included in the first terminal 10 and the operating frequency band of each wireless communication module included in the second terminal 20 is compared and analyzed, a comparison result may be generated; and selects a data transmission mode according to the comparison result.

In one embodiment, the plurality of wireless communication modules included in the first terminal 10 include at least a first module and a second module, and the plurality of wireless communication modules included in the second terminal 20 include at least a first module and a second module. The selection of the data transmission party according to the comparison result can be classified into the following cases:

in an embodiment, if the working frequency bands of the first module of the first terminal 10 and the first module of the second terminal 20 are the same, the working frequency bands of the second module of the first terminal 10 and the second module of the second terminal 20 are the same, but the working frequency bands of the first module and the second module are different, the first terminal 10 selects the data transmission mode corresponding to the first module and the data transmission mode corresponding to the second module.

For example, the first module of the first terminal 10 is a Wi-Fi module, the first module of the second terminal 20 is a Wi-Fi module, the second module of the first terminal 10 is a bluetooth module, and the second module of the second terminal 20 is a bluetooth module. If the working frequency band of the bluetooth module of the first terminal 10 is the same as the working frequency band of the bluetooth module of the second terminal 20, and the working frequency band of the Wi-Fi module of the first terminal 10 is the same as the working frequency band of the Wi-Fi module of the second terminal 20, the working frequency bands between the bluetooth module and the Wi-Fi module are different. The first terminal 10 selects a data transmission mode corresponding to the bluetooth module and a data transmission mode corresponding to the Wi-Fi module.

In an embodiment, if the working frequency bands of the first module of the first terminal 10 and the first module of the second terminal 20 are the same, the working frequency bands of the second module of the first terminal 10 and the second module of the second terminal 20 are the same, and the working frequency bands of the first module and the second module are the same, the first terminal 10 preferentially selects the data transmission mode corresponding to the first module.

For example, the first module of the first terminal 10 is a Wi-Fi module, the first module of the second terminal 20 is a Wi-Fi module, the second module of the first terminal 10 is a bluetooth module, and the second module of the second terminal 20 is a bluetooth module. If the working frequency band of the bluetooth module of the first terminal 10 is the same as the working frequency band of the bluetooth module of the second terminal 20, the working frequency band of the Wi-Fi module of the first terminal 10 is the same as the working frequency band of the Wi-Fi module of the second terminal 20, and the working frequency bands between the bluetooth module and the Wi-Fi module are the same. The first terminal 10 preferentially selects the data transmission mode corresponding to the Wi-Fi module.

In an embodiment, if the working frequency bands between the first module of the first terminal 10 and the first module of the second terminal 20 are the same, the working frequency bands between the second module of the first terminal 10 and the second module of the second terminal 20 are the same, and the working frequency bands between the first module and the second module are the same, the first terminal 10 may query whether there are other working frequency bands in the first module or the second module, if there are other working frequency bands in the first module or the second module, the working frequency bands in the first module or the second module are switched to other working frequency bands, and a data transmission mode corresponding to the first module and a data transmission mode corresponding to the second module are selected.

In an embodiment, if the operating frequency bands between the first module of the first terminal 10 and the first module of the second terminal 20 are the same, the operating frequency bands between the second module of the first terminal 10 and the second module of the second terminal 20 are the same, and the operating frequency bands between the first module and the second module are the same, the first terminal 10 may determine the number of antennas used by the first module and the second module of the first terminal 10 according to the antenna parameter of the first performance information, and may determine the number of antennas used by the first module and the second module of the second terminal 20 according to the antenna parameter of the second performance information. If the number of antennas used by the first module and the second module in the first terminal 10 is one or the number of antennas used by the first module and the second module in the second terminal 20 is one, the first terminal 10 preferentially selects the data transmission mode corresponding to the first module. If the number of antennas used by the first module and the second module in the first terminal 10 is two and the number of antennas used by the first module and the second module in the second terminal 20 is two, the first terminal 10 selects a data transmission mode corresponding to the first module and a data transmission mode corresponding to the second module.

In an embodiment, if the operating frequency bands of the first module of the first terminal 10 and the first module of the second terminal 20 are different, the operating frequency bands of the first module of the first terminal 10 and the first module of the second terminal 20 may be negotiated between the first terminal 10 and the second terminal 20, so that the operating frequency band of the first module of the first terminal 10 may be the same as the operating frequency band of the first module of the second terminal 20, and thus the first terminal 10 and the second terminal 20 establish the second connection in the same operating frequency band. Further, data transmission may be performed over the second connection. If the working frequency bands of the second module of the first terminal 10 and the second module of the second terminal 20 are different, the working frequency bands of the second module of the first terminal 10 and the second module of the second terminal 20 may be negotiated between the first terminal 10 and the second terminal 20, so that the working frequency band of the second module of the first terminal 10 may be the same as the working frequency band of the second module of the second terminal 20, and the first terminal 10 and the second terminal 20 establish a second connection in the same working frequency band. Further, data transmission may be performed over the second connection.

In one embodiment, the establishing, by the first terminal 10, at least one second connection with the second terminal 20 based on the determined data transmission manner may include: if the determined data transmission method does not include the data transmission method corresponding to the first connection, but is another data transmission method, the first terminal 10 may establish at least one second connection with the second terminal 20 based on the determined data transmission method, so as to perform data transmission on the second connection.

For example, if the first terminal 10 and the second terminal 20 establish the first connection through bluetooth, if the determined data transmission mode is a Wi-Fi based transmission mode, the first terminal 10 may establish a second connection through Wi-Fi with the second terminal 20 through the Wi-Fi based transmission mode, and perform data transmission on the second connection established through Wi-Fi.

In one embodiment, the establishing, by the first terminal 10, the second connection with the second terminal 20 based on the determined data transmission manner may further include: if the determined data transmission mode includes a data transmission mode corresponding to the first connection and also includes other data transmission modes, the first terminal 10 may establish at least one second connection with the second terminal 20 through the other data transmission modes, so that data transmission may be performed between the first terminal 10 and the second terminal 20 by using the at least one second connection and the first connection, and multiple second connections may be established for data transmission, thereby increasing the transmission rate.

For example, if a first connection is established between the first terminal 10 and the second terminal 20 through bluetooth, if the determined data transmission mode is a Wi-Fi based transmission mode and a bluetooth based transmission mode, the first terminal 10 may establish a second connection through the Wi-Fi based transmission mode and the second terminal 20 may establish a second connection through the Wi-Fi based transmission mode. After the second connection is established, data transmission can be performed between the first terminal 10 and the second terminal 20 through the second connection established by Wi-Fi, and data transmission can be performed through the first connection established by bluetooth.

In one embodiment, the first terminal 10 may compare and analyze the transmission parameters of each of the at least one second connection, so as to determine a target connection according to the at least one second connection and the transmission parameters, and may interact with the data based on the target connection. Wherein the target connection is a connection selected among the at least one second connection. The target connection may also be a connection established by a data transmission method corresponding to the operating frequency band of the switched wireless communication module.

For example, the first terminal 10 may select a data transmission mode with better transmission performance, such as an operating frequency band with a faster data transmission speed, according to the transmission parameters to establish the second connection, thereby improving the data transmission efficiency. That is to say, if the first terminal 10 detects that the data transmission performance based on the second connection is poor, or determines that the transmission performance of the other operating frequency bands of the wireless communication module is better, the first terminal 10 establishes the second connection with the second terminal 20 according to the data transmission mode of the operating frequency band with the better determined transmission performance, so as to perform switching of the data transmission modes of different operating frequency bands according to the transmission performance condition of the second connection established between the terminals, thereby effectively improving the efficiency of data transmission. Alternatively, the first terminal 10 may send test data to the second terminal 20 to test the data transmission manner.

In one embodiment, when the determined data transmission mode includes a Wi-Fi based transmission mode, if the first terminal 10 and the second terminal 20 do not establish the second connection through the Wi-Fi based transmission mode within a preset time period, determining whether the first terminal 10 and the second terminal 20 have established a Wi-Fi hotspot connection by using the second module; if the Wi-Fi hotspot connection is not established, triggering the establishment of the Wi-Fi hotspot connection between the first terminal 10 and the second terminal 20, so that the first terminal 10 and the second terminal 20 establish at least one second connection. The above manner of triggering the establishment of the hotspot includes, but is not limited to, triggering in the form of a notification message. Optionally, when the first module includes a plurality of working frequency bands, the user may select a working frequency band under the Wi-Fi hotspot, and the first terminal 10 may establish a second connection with a second terminal according to a data transmission mode of the selected working frequency band.

In one embodiment, the second terminal 20 may also be provided with the functionality implemented by the first terminal 10.

As can be seen from fig. 1, after the first terminal establishes the first connection with the second terminal, the first terminal and the second terminal may negotiate about a data transmission method, so that at least one second connection may be established according to the negotiated data transmission method, and data may be exchanged based on the at least one second connection.

Fig. 2 is a schematic flow chart of a data transmission method according to an embodiment of the present invention. Wherein, the method can be applied to the system architecture shown in fig. 1. Moreover, the method can be applied to terminals including but not limited to smart terminals with a plurality of wireless communication modules, such as mobile phones, tablet computers and the like. Specifically, the method may include:

s201, a first connection is established between a first terminal and a second terminal.

In the embodiment of the present invention, the first connection includes, but is not limited to, a radio frequency based connection, such as an NFC-based connection, a bluetooth-based connection, an ultrasonic-based connection, and other connections.

S202, the first terminal obtains first performance information of the first terminal and obtains second performance information of the second terminal through the first connection.

It should be noted that the first terminal may include a plurality of wireless communication modules, and the second terminal may also include a plurality of wireless communication modules, so that at least one connection is established between the first terminal and the second terminal. Further, data may be exchanged over the established at least one connection. The plurality of wireless communication modules include, but are not limited to, a radio frequency module, a bluetooth module, a Wi-Fi module, an ultrasonic module, and other modules that can be used for wireless communication.

In this embodiment of the present invention, the aforementioned first performance information may include parameters for determining data transmission capabilities of a plurality of wireless communication modules of the first terminal, such as a maximum data transmission speed and a data transmission range supported by each of the plurality of wireless communication modules, data transmission types (such as large data transmission and small data transmission) respectively applicable to each of the plurality of wireless communication modules, or identifiers of the plurality of wireless communication modules. In addition, the first performance information may further include parameters for determining an operating frequency band of a plurality of wireless communication modules of the first terminal, including but not limited to a first terminal identifier, identifiers of the plurality of wireless communication modules, or a value of an operating frequency band preset for the wireless communication module.

In this embodiment of the present invention, the aforementioned second performance information may include parameters for determining data transmission capabilities of a plurality of wireless communication modules of the second terminal, such as a maximum data transmission speed and a data transmission range supported by each of the plurality of wireless communication modules, data transmission types (such as large data transmission and small data transmission) respectively applicable to each of the plurality of wireless communication modules, or identifiers of the plurality of wireless communication modules. In addition, the second performance information may further include parameters for determining an operating frequency band of a plurality of wireless communication modules included in the second terminal, including, but not limited to, a first terminal identifier, identifiers of the plurality of wireless transmission modules, or a value of an operating frequency band preset for the wireless communication module.

Optionally, the second performance information may be sent to the first terminal by the second terminal after the first connection is established between the first terminal and the second terminal. Alternatively, the second capability information may be obtained by the first terminal from a memory.
