Several concepts related to embodiments of the present application are described below:

and (3) short-distance point-to-point transmission: the way in which two communication parties transmit information by radio within a small transmission distance may be referred to as short-range point-to-point transmission. In particular, close range point-to-point transmission includes bluetooth, Wi-Fi direct, NFC, and the like.

Bluetooth: a radio technology supporting short-range communication of devices uses the industrial, scientific and medical (ISM) band of 2.4 to 2.485GHz for wireless communication between various fixed and mobile digital hardware devices. Bluetooth technology supports point-to-point connections and point-to-multipoint connections, while supporting data and voice services, based on low cost short-range wireless connections.

Wi-Fi direct: an 802.11-based peer-to-peer connection technology established by the Wi-Fi alliance, Wi-Fi direct may also be referred to as Wi-Fi peer-to-peer (Wi-Fi peer-to-peer, Wi-Fi P2P). Wi-Fi direct uses the 802.11 physical layer to modify the existing 802.11 Media Access Control (MAC) layer and above, making it suitable for the scene from discovery to establishment of point-to-point connection between two devices.

NFC: a short-distance high-frequency radio technology is evolved from non-contact radio frequency identification, an induction card reader, an induction card and a point-to-point function are combined on a single chip, identification and data interaction can be carried out on compatible equipment in a short distance, the working frequency is 13.56MHz, the transmission distance is less than or equal to 0.2 m, the effective distance is 4cm, and the transmission rate is 106kbit/s, 212kbit/s, 424kbit/s, 848kbit/s and the like.

In addition to short range point-to-point transmission, devices may also wirelessly transmit data between themselves via WLAN and cellular networks.

WLAN: a local area network is constructed using radio waves or electric fields in connection with magnetic fields as a medium for data transfer. Can provide high-speed wireless data access in a small range, and the transmission distance is generally only dozens of meters. The backbone network of a wlan typically uses a wired network, and wlan subscribers access the wlan through one or more wireless access devices.

Cellular network: a mobile communication hardware architecture, also called mobile network, is divided into an analog cellular network and a digital cellular network. Since the signal coverage of each communication base station forming the network coverage is hexagonal, the whole network is named like a honeycomb. The cellular network mainly comprises a mobile terminal, a base station subsystem and a network subsystem. Common types of cellular networks are: a global system for mobile communications (GSM) network, a Code Division Multiple Access (CDMA) network, a third generation mobile communication technology (3rd-generation, 3G) network, a fourth generation mobile communication technology (4rd-generation, 4G) network, a fifth generation mobile communication technology (5rd-generation, 5G) network, and the like.

Soft routing: the routing solution is formed by utilizing electronic equipment or a server to cooperate with software, and the function of the router is realized mainly by the setting of the software.

Hard routing: the method adopts specific hardware equipment, is based on an embedded system architecture, takes a self-developed or ready-made embedded operating system as an operating system, and provides a special router function by matching with routing software self-developed by a system manufacturer, wherein the software is matched with the hardware.

It should be noted that, unless otherwise specified, a plurality of electronic devices related to the present application all trust each other.

Alternatively, the electronic devices that are trusted with each other may be multiple electronic devices that log into the same account.

Specifically, the plurality of electronic devices logged in to the same account include, but are not limited to, a plurality of electronic devices of the same user.

Alternatively, a user may have only one account or multiple accounts.

Alternatively, when the electronic device logs in to an account, the electronic device may associate device information of the electronic device with the account and transmit the device information and the account to the account management server together. The same account number may be logged on multiple electronic devices. The account management server may record device information for a plurality of electronic devices associated with the account. The device information includes at least one of: an Identifier (ID), location information, a name, a physical address, network information, a remaining power of the electronic device. The network information of the electronic device may include at least one of: the working frequency band of the electronic equipment, the name of the connected routing equipment, the password, the available bandwidth and the working frequency band.

Optionally, the account management server stores accounts which are trusted with each other in advance. Further, the account management server stores accounts which trust each other in advance in the form of an account group. The account management server compares the received different login accounts with the pre-stored accounts in the group after receiving the different login accounts from the plurality of electronic devices, and if all or part of the different login accounts belong to the same group of accounts, the account management server indicates that all or part of the different login accounts are mutually trusted, so that the plurality of electronic devices are mutually trusted. If the login accounts received by the account management server from the plurality of electronic devices are the same account, the login accounts do not need to be compared with the account in the pre-stored group, and the fact that the plurality of electronic devices trust each other is directly indicated.

Alternatively, the electronic devices that are trusted with each other may be multiple electronic devices that log in to different accounts and/or the same account in the same group. For example, the electronic device a logs in the account 1, the electronic device B logs in the account 2, the electronic device C logs in the account 3, and the electronic device D logs in the account 3, and the accounts 1, 2, and 3 belong to the same group. For another example, the electronic device a logs in the account 1, the electronic device B logs in the account 2, and the electronic device C logs in the account 3, and the accounts 1, 2, and 3 belong to the same group.

The group can be a group created by a user in application software. The application software includes, but is not limited to, operating system software, pre-installed software, third party application software, etc. bound or associated with the login account of the electronic device.

Specifically, the user may create a group by adding or scanning accounts or business cards of other users, where the group includes login accounts of two or more electronic devices, and even further includes a device ID. Different electronic devices log in to different accounts. For example, the group includes a login account 1 of the electronic device a, a login account 2 of the electronic device B, and even further includes device IDs of the electronic device a and the electronic device B.

Optionally, the group may also include different electronic devices that log into the same account. For example, the group also includes the login account number 2 and the device ID of the electronic device C. The group may show: account 1 (device ID of electronic device a), account 2 (device ID of electronic device B), and account 2 (device ID of electronic device C). As another example, the group may include only the login accounts of electronic device B and electronic device C, and even the device ID. The group may show: account 2 (device ID of electronic device B) and account 2 (device ID of electronic device C).

Optionally, the account management server may associate and store the identifier of the group with the login account of the electronic device in the group and the device ID of the electronic device. Optionally, after the plurality of electronic devices establish the group, the plurality of electronic devices send the group identifier, the login account of each electronic device, and the device information to the account management server. And the account management server stores the login account, the equipment information and the group identification in a correlation manner. Optionally, a group may be further established in the account management server, where the group includes a group identifier, a login account of each electronic device, and device information.

A data transmission system according to an embodiment of the present application will be described with reference to fig. 1.

Fig. 1 schematically shows a structural diagram of a data transmission system provided in an embodiment of the present application. As shown in fig. 1, the data transmission system includes:

electronic devices

10a, 10b, 10c, and 10d, and an account management server (not shown). And each electronic device sends the login account to the account management server. The account management server acquires the login account of each electronic device and identifies whether all or part of the login accounts of the electronic devices are mutually trusted. Whether the related accounts are mutually trusted can be identified and judged in the following way. For example, the login accounts of multiple electronic devices belong to the same group and/or are the same account. The account number may be a hua account number or an account number of another manufacturer. In addition, different manufacturer accounts can also form the same group. For example, at least two of the hua account number, the manufacturer account number a and the manufacturer account number B form the same group. The manufacturer A and the manufacturer B are different from Hua. In addition, in the same group, there may be a plurality of accounts of some manufacturers. For example, at least two of hua account 1, hua account 2, manufacturer account a, and manufacturer account B form the same group.

The account management server is used for identifying and judging whether the plurality of electronic devices logging in the account are mutually trusted, maintaining the device information of the plurality of mutually trusted electronic devices, and adding or modifying the account information and/or the device information. Further, the account management server can also notify the electronic devices that trust each other of the online and offline messages of different accounts and/or different electronic devices under the same account in real time.

For clarity of illustration, the account management server stores a database, for example. The database stores a plurality of accounts which trust each other and equipment information of electronic equipment corresponding to each account. One account may correspond to device information of a plurality of electronic devices. The account management server identifies and judges whether the relations between the connected electronic equipment login accounts are mutually trusting or not by inquiring the database. An authorized administrator can log in the account management server and add or modify a plurality of accounts which are mutually trusted. The electronic device logging in the account may also provide requests for establishing a group, dismissing the group, adding group members, removing group members, and the like, and after verifying that the electronic device has the relevant authority, corresponding operations are correspondingly performed. The electronic device of any login account can have the authority to establish the group, and after the group is established, the electronic device can set that a certain member has the management authority of the group. When a group member is added, the added member is required to approve, and the member is successfully added to the group. When a group member is removed, the member's consent is not required. The establishment and the resolution of the group, the addition and the removal of the group members and the like are maintained in the account management server. Taking the electronic device 10a as an example, specifically, after the electronic device 10a logs in an account, the electronic device 10a sends the login account and device information of the electronic device 10a to the account management server. And after receiving the login account, the account management server inquires the login account and correspondingly maintains the equipment information corresponding to the account.

Optionally, the communication connection between the electronic device and the account management server includes a direct connection and an indirect connection. For example, the electronic device is in communication connection with the account management server through the routing device. Wherein the routing device comprises any electronic device capable of implementing a routing function.

And data transmission is carried out among the electronic equipment which are mutually trusted. Firstly, determining an available data transmission mode; secondly, selecting an optimal data transmission mode from the available data transmission modes for data transmission.

Several embodiments provided by the present application are described below.

The first embodiment is as follows: the first electronic device and the second electronic device are at most related to two modes of short-distance point-to-point transmission and cellular network transmission.

Fig. 3 shows a schematic structural diagram of a wireless data transmission system according to an embodiment of the present application. As shown in fig. 3, the wireless data transmission system includes: a first electronic device 310, a second electronic device 320, and an account management server (not shown).

The first electronic device 310 and the second electronic device 320 are respectively connected to an account management server. The connection includes direct or indirect connection. The first electronic device 310 and the second electronic device 320 may both log in accounts that are trusted with each other, such as the same account (account a), and accounts of the same group (account a, account B). The account management server obtains login account information and device information of the first electronic device 310 and the second electronic device 320, and determines whether the login accounts of the first electronic device 310 and the second electronic device 320 are trusted with each other. The device information includes at least a device ID and location information (e.g., GPS coordinates, BDS coordinates, QZSS coordinates, SBAS coordinates, etc.). After determining that the respective login accounts of the first electronic device 310 and the second electronic device 320 are mutually trusted, the account management server feeds back the mutual trust of the login accounts of the first electronic device 310 and the second electronic device 320 to the first electronic device 310 and the second electronic device 320, and sends device information of the second electronic device 320 to the first electronic device 310. Further, the account management server also transmits the device information of the first electronic device 310 to the second electronic device 320.

Optionally, after determining that the login accounts of the first electronic device 310 and the second electronic device 320 are trusted with each other, the account management server sends the device information of the second electronic device 320 to the first electronic device 310, and does not feed back that the login accounts are trusted with each other to the first electronic device 310 and the second electronic device 320. At this time, when the first electronic device 310 receives the device information of the second electronic device 320 sent by the account management server, it is default that the login accounts of the first electronic device 310 and the login account of the second electronic device 320 are trusted with each other. Further, the account management server also transmits the device information of the first electronic device 310 to the second electronic device 320. Similarly, the second electronic device 320 receives the device information of the first electronic device 310 sent by the account management server, and then the login accounts of the first electronic device 310 and the second electronic device 320 are defaulted to trust each other.

Optionally, after the account management server determines that the respective login accounts of the first electronic device 310 and the second electronic device 320 are not trusted with each other, the account management server feeds back that the login accounts of the first electronic device 310 and the second electronic device 320 are not trusted with each other. At this time, if the first electronic device 310 and the second electronic device 320 both feed back that they are willing to establish mutual trust, or if the first electronic device 310 and the second electronic device 320 both feed back that they are willing to perform the communication on the basis of not establishing mutual trust, the account management server still sends the device information of the second electronic device 320 to the first electronic device 310, and sends the device information of the first electronic device 310 to the second electronic device 320.

After the account management server feeds back, to the first electronic device 310 and the second electronic device 320, that the login accounts are mutually trusted and sends the device information of the second electronic device 320 to the first electronic device 310, the first electronic device 310 preliminarily determines the distance between the first electronic device 310 and the second electronic device 320 according to the device information of the first electronic device 310 and the device information of the second electronic device 320, and preliminarily determines a data transmission mode capable of performing data transmission between the first electronic device 310 and the second electronic device 320 according to the distance. Further, the account management server sends the positioning information of the second electronic device 320 to the first electronic device 310. The first electronic device 310 preliminarily determines a distance between the first electronic device 310 and the second electronic device 320 according to the location information of itself and the location information of the second electronic device 320.

Specifically, the first electronic device 310 preliminarily determines, according to the distance, a data transmission mode capable of performing data transmission between the first electronic device 310 and the second electronic device 320, and the data transmission mode is determined by a relationship between the distance and the first threshold. The first threshold is preset according to the characteristics of a close-range point-to-point transmission mode (such as Bluetooth, NFC, Wi-Fi direct connection and the like). For example, the first threshold is 1 meter, 2.6 meters, 5 meters, etc. If the distance is greater than the first threshold, it is preliminarily determined that the first electronic device 310 and the second electronic device 320 cannot establish a communication connection in a close-range peer-to-peer transmission manner. Otherwise, it is preliminarily determined that the first electronic device 310 and the second electronic device 320 can establish a communication connection in two data transmission modes, namely, a short-range point-to-point transmission mode and a cellular network transmission mode.

Then, the first electronic device 310 attempts to establish a communication connection with the second electronic device 320 through the preliminarily determined data transmission manner, respectively. After a predetermined period of time and/or a predetermined number of transmissions, the available data transmission modes with which a communication connection can be established are determined. The available data transmission mode can be one or more data transmission modes. Then, according to the priority level, the first electronic device 310 selects the available data transmission mode with the highest priority level as the data transmission mode to be subsequently adopted.

Specifically, the first electronic device 310 only sends a data transmission request through one data transmission method, and if the first electronic device 310 receives a response message of the second electronic device 320 within a preset time duration and/or a preset number of sending times, it indicates that the communication connection of the data transmission method can be established between the first electronic device 310 and the second electronic device 320; if the first electronic device 310 does not receive the response message of the second electronic device 320 within the preset time duration or the preset number of times of transmission, it indicates that the communication connection of the data transmission manner cannot be established between the first electronic device 310 and the second electronic device 320. According to the process, the first electronic device 310 sequentially sends the data transmission request through one of the preliminarily determined data transmission manners, and determines whether the response message of the second electronic device 320 is received within the same preset time duration or preset sending times.

If the communication connection between the short-distance peer-to-peer transmission mode and the cellular network transmission mode can be established, the first electronic device 310 selects the communication connection mode between the first electronic device 310 and the second electronic device 320 as the short-distance peer-to-peer transmission mode because the priority of the short-distance peer-to-peer transmission mode is higher than that of the cellular network transmission mode.

If the communication connection of the close-range point-to-point transmission mode cannot be established, the communication connection of the cellular network transmission mode can only be established, and the first electronic device 310 selects the communication connection mode between the first electronic device 310 and the second electronic device 320 as the cellular network transmission mode.

When the distance between the first electronic device 310 and the second electronic device 320 is large, the first electronic device 310 preliminarily determines that the data transmission mode capable of performing data transmission between the two devices is only the cellular network transmission mode. Then, the process of specifically determining the data transmission mode capable of establishing the communication connection is similar to that described above, and details are not described here.

If the communication connection of the cellular network transmission method can be established, the first electronic device 310 selects the communication connection method between the first electronic device 310 and the second electronic device 320 as the cellular network transmission method.

Considerations for data transfer mode priority include, but are not limited to, at least one of data transfer speed, cost, security, stability, and the like.

Optionally, when the first electronic device 310 attempts to establish a communication connection with the second electronic device 320 through the preliminarily determined data transmission modes, the data transmission mode with the higher priority is preferentially selected according to the priority, and the communication connection with the second electronic device 320 is attempted. When the data transmission mode with the highest priority cannot establish the communication connection, the data transmission mode with the second priority is selected to attempt to establish the communication connection with the second electronic device 320. And so on.

Optionally, the account management server only obtains login account information of the first electronic device 310 and the second electronic device 320, and determines whether the login accounts of the first electronic device 310 and the second electronic device 320 are trusted with each other. After determining whether the respective login accounts of the first electronic device 310 and the second electronic device 320 are mutually trusted, the account management server feeds back to the first electronic device 310 and the second electronic device 320 whether the login accounts are mutually trusted.

After the account management server feeds back that the login accounts of the first electronic device 310 and the second electronic device 320 are trusted with each other, the first electronic device 310 tries to establish a communication connection with the second electronic device 320 through multiple data transmission methods. After a predetermined period of time and/or a predetermined number of transmissions, a data transmission mode is determined in which a communication connection can be established. The data transmission mode can be one or more data transmission modes. Then, according to the priority level, the first electronic device 310 selects the data transmission mode with the highest priority level as the data transmission mode to be subsequently adopted.

Further, the first electronic device 310 only sends the data transmission request through one data transmission method, and if the first electronic device 310 receives the response message of the second electronic device 320 within the preset time duration and/or the preset sending times, it indicates that the communication connection of the data transmission method can be established between the first electronic device 310 and the second electronic device 320; if the first electronic device 310 does not receive the response message of the second electronic device 320 within the preset time duration and/or the preset number of times of transmission, it indicates that the communication connection in the data transmission manner cannot be established between the first electronic device 310 and the second electronic device 320. According to the process, the first electronic device 310 sequentially transmits a data transmission request through one of the three data transmission modes, and determines whether a response message of the second electronic device 320 is received within the same preset time length and/or preset transmission times; thereby determining which data transfer mode communication connections can be established between the first electronic device 310 and the second electronic device 320.

The preset time period may be a time period such as 3 seconds, 5.5 seconds, 10 seconds, or other time periods.

The preset number of times of transmission may be, for example, 3 times, 6 times, 8 times, or other numbers.

The above "and/or" and "in" mean and.

Optionally, a communication connection of a certain data transmission mode is successfully/unsuccessfully established between the first electronic device 310 and the second electronic device 320, and the information is displayed on the first electronic device 310 and/or the second electronic device 320, and a prompt is fed back to the user.

Alternatively, in some cases, such as when the first electronic device 310 and the second electronic device 320 cannot be successfully connected to the account management server (or are disconnected after being successfully connected for some reason), and thus the relationship between the respective login accounts of the first electronic device 310 and the second electronic device 320 cannot be confirmed by the account management server, if the first electronic device 310 and the second electronic device 320 both wish to communicate, the first electronic device 310 and the second electronic device 320 determine whether the two can establish a communication connection in the foregoing manner; if the communication connection between the short-distance point-to-point transmission mode and the cellular network transmission mode can be established, the data transmission mode with the highest priority is selected to carry out data transmission in the selectable data transmission modes.

Optionally, the priority of each data transmission mode is preset and stored in the electronic device in advance. In fig. 1, the electronic device is a first electronic device and/or a second electronic device.

Optionally, the first electronic device does not pre-store the priority of each data transmission mode, but first obtains the available data transmission mode, then determines the data transmission mode with the highest priority by comprehensively considering the priority factors of the data transmission modes, and selects the mode for data transmission.

Optionally, information sent between at least two of the first electronic device 310, the second electronic device 320, and the account management server may be encrypted information, so as to ensure information security. Optionally, decryption is performed after the encrypted information is received.

Therefore, in the first embodiment, at most two optional data transmission modes exist between the first electronic device and the second electronic device. The first is a short-distance point-to-point transmission mode, and the second is a cellular network transmission mode. When only one data transmission mode exists, such as a short-distance point-to-point transmission mode (such as a cellular network failure, which cannot be used), or a cellular network transmission mode, because the priority of the cellular network transmission mode is already the highest, the data transmission mode is only used for transmission. When two data transmission modes exist, the data transmission mode with the highest priority, such as a short-distance point-to-point transmission mode, is selected according to the priority for transmission. That is to say, in an optional situation, the first electronic device selects the data transmission mode with the highest priority for transmission according to the priority corresponding to the data transmission mode. Optionally, the priority of the cellular network transmission mode can be set to be higher than that of the short-distance point-to-point transmission mode. Those skilled in the art will appreciate that the components of the first embodiment can be freely combined.

Example two: the first electronic device and the second electronic device are involved in at most two ways, WLAN transmission and cellular network transmission.

Fig. 4 a-4 b are schematic structural diagrams illustrating a wireless data transmission system according to a second embodiment of the present application. As shown in fig. 4a, the wireless data transmission system includes: a first electronic device 410, a second electronic device 420, a routing device 430, and an account management server (not shown). First electronic device 410 and/or second electronic device 420 are connected to routing device 430. The connection includes direct connection and indirect connection. Where indirectly connected, first electronic device 410 and/or second electronic device 420 are connected to routing device 430 through other devices.

The determination as to whether the respective login account relationships of the first electronic device 410 and the second electronic device 420 are mutually trusted is the same as the related description in the first embodiment; the determination of the available data transmission method between the first electronic device 410 and the second electronic device 420 after mutual trust is similar to the description in the first embodiment, and is not repeated here.

After the above process, the first electronic device 410 and the second electronic device 420 perform at most two modes, namely WLAN transmission and cellular network transmission, further determining:

as shown in fig. 4a, when the first electronic device 410 and the second electronic device 420 can establish a connection of WLAN transmission mode through the routing device 430, and the first electronic device 410 and the second electronic device 420 can establish a connection of cellular network transmission mode, the communication connection mode between the first electronic device 410 and the second electronic device 420 is selected as WLAN transmission mode because the priority of WLAN transmission mode is higher than that of cellular network transmission mode.

As shown in fig. 4b, when the first electronic device 410 cannot be connected to the routing device 430 and the second electronic device 420 can be connected to the routing device 430, so that the first electronic device 410 and the second electronic device 420 cannot establish a connection of the WLAN transmission method and can only establish a connection of the cellular network transmission method, the communication connection method between the first electronic device 410 and the second electronic device 420 is selected as the cellular network transmission method.

Optionally, the information sent between at least two of the first electronic device 410, the second electronic device 420, the routing device 430, and the account management server may be encrypted information to ensure information security. Optionally, decryption is performed after the encrypted information is received.

Therefore, in the second embodiment, at most two optional data transmission modes exist between the first electronic device and the second electronic device. The first is WLAN transmission mode, and the second is cellular network transmission mode. When there is only one data transmission mode, such as WLAN transmission mode (e.g. cellular network failure, unable to use), or cellular network transmission mode, since its priority is already the highest, only this data transmission mode is used for transmission. When two data transmission modes exist, the data transmission mode with the highest priority, such as the WLAN transmission mode, is selected for transmission according to the priority. That is to say, in an optional situation, the first electronic device selects the data transmission mode with the highest priority for transmission according to the priority corresponding to the data transmission mode. Optionally, the priority of the cellular network transmission mode may be set higher than the priority of the WLAN transmission mode.

In the case of no specific description, the related contents related to the second embodiment of the present application are the same as those related contents related to the first embodiment of the present application, and are not described herein again. Those skilled in the art will appreciate that the parts of the second embodiment can be freely combined.

Example three: the first electronic device and the second electronic device are at most related to two modes of short-distance point-to-point transmission and WLAN transmission.

Fig. 5 a-5 b are schematic structural diagrams illustrating a wireless data transmission system according to a third embodiment of the present application. As shown in fig. 5a, the wireless data transmission system includes: a first electronic device 510, a second electronic device 520, a routing device 530, and an account management server (not shown). The first electronic device 510 and/or the second electronic device 520 are connected to a routing device 530. The connection includes direct connection and indirect connection.

The determination as to whether the respective login account relationships of the first electronic device 510 and the second electronic device 520 are mutually trusted is the same as the related description in the first embodiment; the determination of the available data transmission method between the first electronic device 510 and the second electronic device 520 after mutual trust is similar to the description in the first embodiment, and is not repeated here.

After the above process, the first electronic device 510 and the second electronic device 520 may perform at most two ways, namely, near-distance peer-to-peer transmission and WLAN transmission, and then further determine:

as shown in fig. 5a, when both the first electronic device 510 and the second electronic device 520 can establish a connection between a close-range peer-to-peer transmission mode and a WLAN transmission mode, the communication connection mode between the first electronic device 510 and the second electronic device 520 is selected to be the close-range peer-to-peer transmission mode because the priority of the close-range peer-to-peer transmission mode is higher than the priority of the WLAN transmission mode.

As shown in fig. 5b, when the first electronic device 510 and the second electronic device 520 cannot establish a connection by a close-range peer-to-peer transmission method, but both the first electronic device 510 and the second electronic device 520 can be connected to the routing device 530, the communication connection method between the first electronic device 510 and the second electronic device 520 is selected as a WLAN transmission method. At this time, when the first electronic device 510 initiates a data transmission request to the second electronic device 520 through the WLAN transmission mode; the second electronic device 520 receives the data transmission request through the WLAN transmission method and responds. Likewise, in this process, the main subject of selecting the communication connection mode between the first electronic device 510 and the second electronic device 520 may be only the first electronic device 510 and/or the second electronic device 520, instead of the account management server; or an account management server.

Optionally, the information sent between at least two of the first electronic device 510, the second electronic device 520, the routing device 530, and the account management server may be encrypted information to ensure information security. Optionally, decryption is performed after the encrypted information is received.

Therefore, in the third embodiment, at most two optional data transmission modes exist between the first electronic device and the second electronic device. The first is a short-distance point-to-point transmission mode, and the second is a WLAN transmission mode. When there is only one data transmission method, such as a short-distance point-to-point transmission method (e.g. a failure of the routing device 530) or a WLAN transmission method, only the data transmission method is used for transmission. When two data transmission modes exist, the data transmission mode with the highest priority, such as a short-distance point-to-point transmission mode, is selected according to the priority for transmission. That is to say, in an optional situation, the first electronic device selects an optimal data transmission method for transmission according to the priority corresponding to the data transmission method. Alternatively, the priority of the WLAN transmission mode may be set higher than the priority of the short-range point-to-point transmission mode.

In the case that no specific description is given, relevant contents related to the third embodiment of the present application are the same as or similar to relevant contents related to any one of the foregoing embodiments of the present application, and are not described herein again.

Fig. 6 shows a schematic structural diagram of a wireless data transmission system according to a fourth embodiment of the present application. As shown in fig. 6, the data transmission system includes: a first electronic device 610, a second electronic device 620, a routing device 630, and an account management server (not shown).

The determination as to whether the respective login account relationships of the first electronic device 610 and the second electronic device 620 are mutually trusted is the same as the related description in the first embodiment; the determination of the available data transmission mode between the first electronic device 610 and the second electronic device 620 after mutual trust is the same as the description in the first embodiment, and is not described herein again.

After the above processes, the first electronic device 610 and the second electronic device 620 at most relate to the short-distance peer-to-peer transmission and mode, the WLAN transmission mode and the cellular network transmission mode, further determining:

when the first electronic device 610 and the second electronic device 620 can both establish connection in three data transmission modes, the communication connection mode between the first electronic device 610 and the second electronic device 620 is selected to be a near-range point-to-point transmission mode because the priority of the near-range point-to-point transmission mode is higher than the priorities of the other two transmission modes.

When the first electronic device 610 and the second electronic device 620 can only establish a connection between two data transmission modes, such as a WLAN transmission mode and a cellular network transmission mode, the communication connection mode between the first electronic device 610 and the second electronic device 620 is selected as the WLAN transmission mode because the priority of the WLAN transmission mode is higher than that of the cellular network transmission mode.

When the first electronic device 610 and the second electronic device 620 can only establish a connection of one data transmission mode, such as a cellular network transmission mode, the communication connection mode between the first electronic device 610 and the second electronic device 620 is selected as the cellular network transmission mode.

Therefore, in the fourth embodiment, at most three selectable data transmission modes exist between the first electronic device and the second electronic device. The first is a short-distance point-to-point transmission mode, the second is a WLAN transmission mode, and the third is a cellular network transmission mode. When only one data transmission mode exists, such as a short-distance point-to-point transmission mode, a WLAN transmission mode or a cellular network transmission mode, the data transmission mode is only used for transmission because the priority of the data transmission mode is the highest. And when more than two data transmission modes exist, selecting the data transmission mode with the highest priority for transmission according to the priority. That is to say, in an optional situation, the first electronic device selects the data transmission mode with the highest priority for transmission according to the priority corresponding to the data transmission mode. Alternatively, the priority of the WLAN transmission mode may be set higher than the priority of the short-range point-to-point transmission mode.

In the case of no specific description, related contents related to the fourth embodiment of the present application are the same as or similar to related contents related to any of the foregoing embodiments of the present application, and are not described herein again. Those skilled in the art will appreciate that the parts of the fourth embodiment can be freely combined.

Example five: more than three electronic devices are related to two modes of short-distance point-to-point transmission and cellular network transmission at most.

When more than three electronic devices are related to at most two modes of short-distance point-to-point transmission and cellular network transmission, the data transmission mode is also selected between any two electronic devices according to the first embodiment. And will not be described in detail herein.

The connection for determining whether or not the short-distance point-to-point transmission method can be established between two electronic devices among the three or more electronic devices includes a direct connection and an indirect connection.

For clarity of illustration, three electronic devices are illustrated. Fig. 7 a-7 b are schematic structural diagrams illustrating a wireless data transmission system according to a fifth embodiment of the present application. As shown in fig. 7a, it is determined that the data transmission method between the first electronic device 710 and the second electronic device 720 is the short-distance peer-to-peer transmission method, and the data transmission method between the second electronic device 720 and the third electronic device 730 is the short-distance peer-to-peer transmission method. Optionally, after selecting the data transmission mode between the second electronic device 720 and the third electronic device 730, the second electronic device 720 sends the data transmission mode between the second electronic device 720 and the third electronic device 730 to the first electronic device 710.

In this way, the first electronic device 710 can establish a communication connection with the third electronic device 730 via the second electronic device 720 by means of a short-range point-to-point transmission method. Therefore, the data transmission method between the first electronic device 710 and the third electronic device 730 is also selected to be a short-range point-to-point transmission method, and the cellular network transmission method is not selected.

Further, in the case of four or more electronic devices, in the above manner, there may be a plurality of routing situations. Four electronic devices are taken as an example for explanation. For example, as shown in fig. 7b, it is determined that the data transmission method between the first electronic device 710 and the second electronic device 720, and the data transmission method between the first electronic device 710 and the third electronic device 730 are both short-distance point-to-point transmission methods, and the data transmission method between the second electronic device 720 and the fourth electronic device 740, and the data transmission method between the third electronic device 730 and the fourth electronic device 740 are both short-distance point-to-point transmission methods. Optionally, the second electronic device 720 sends the data transmission mode between the second electronic device 720 and the fourth electronic device 740 to the first electronic device 710. The third electronic device 730 transmits a data transmission mode between the third electronic device 730 and the fourth electronic device 740 to the first electronic device 710.

In this way, the data transmission method between the first electronic device 710 and the fourth electronic device 740 is also selected to be a short-range point-to-point transmission method (via the second electronic device 720 or the third electronic device 730). Then, it is further determined that at least one of the remaining power, the computing power, the available bandwidth, the security, the stability, and the like of the second electronic device 720 and the third electronic device 730 is integrated, and the electronic device with the strongest integrated capability is selected as the soft route, for example, the integrated capability of the second electronic device 720 is stronger than that of the third electronic device 730, and then the first electronic device 710 and the fourth electronic device 740 are selected to establish the communication connection via the second electronic device 720 in the short-distance peer-to-peer transmission manner.

In the case that no specific description is given, relevant contents related to the fifth embodiment of the present application are the same as or similar to relevant contents related to any one of the foregoing embodiments of the present application, and are not described herein again. Those skilled in the art will appreciate that the parts of the fifth embodiment can be freely combined.

Example six: more than three electronic devices are involved in at most two modes, WLAN transmission and cellular network transmission.

When three or more electronic devices are involved in at most two modes, namely WLAN transmission and cellular network transmission, the data transmission mode is also selected between any two electronic devices according to the second embodiment. And will not be described in detail herein.

It should be noted that the connection for determining whether the WLAN transmission mode can be established between two electronic devices of the three or more electronic devices includes a direct connection and an indirect connection.

For clarity of illustration, three electronic devices are illustrated. For example, after the determination, the data transmission method between the first electronic device and the second electronic device is selected to be a WLAN transmission method, and the data transmission method between the second electronic device and the third electronic device is selected to be a WLAN transmission method. Optionally, the second electronic device sends the first electronic device to the second electronic device in a WLAN transmission mode.

In this way, the first electronic device can establish a communication connection with the third electronic device via the second electronic device by means of WLAN transmission. Therefore, the data transmission mode between the first electronic device and the third electronic device is also selected to be the WLAN transmission mode, and the cellular network transmission mode is not selected.

In the case of four or more electronic devices, there may be a plurality of routing situations in the manner described above. Similar to the description in the fifth embodiment, the selection of the specific route may be performed by integrating at least one factor of the remaining power, the computing capability, the available bandwidth, the security, the stability, and the like, and selecting the electronic device with the strongest integrated capability as the soft route, which is not described herein again.

In the case of no specific description, related contents related to the sixth embodiment of the present application are the same as or similar to related contents related to any of the foregoing embodiments of the present application, and are not described herein again. Those skilled in the art will appreciate that the parts of the sixth embodiment can be freely combined.

Example seven: more than three electronic devices are related to two modes of short-distance point-to-point transmission and WLAN transmission at most.

When more than three electronic devices are related to at most two modes, namely, near-distance point-to-point transmission and WLAN transmission, the data transmission mode is also selected between any two electronic devices according to the third embodiment. And will not be described in detail herein.

For clarity of illustration, three electronic devices are illustrated. For example, after the determination, the data transmission mode between the first electronic device and the second electronic device is selected to be a short-distance point-to-point transmission mode, and the data transmission mode between the second electronic device and the third electronic device is selected to be a short-distance point-to-point transmission mode. Optionally, the second electronic device sends a data transmission mode between the second electronic device and the third electronic device to the first electronic device.

Specifically, the first electronic device, the second electronic device and the third electronic device send respective login accounts and device information to an account management server at a predetermined frequency; the device information includes positioning information; after detecting that the first electronic equipment transmits a file to the third electronic equipment, the first electronic equipment sends a request message to an account management server; the request message is used for acquiring the trust relationship between any two of the first electronic equipment, the second electronic equipment and the third electronic equipment; after the account management server receives the request message, the account management server judges the trust relationship of any two of the first electronic equipment, the second electronic equipment and the third electronic equipment; after the judgment result reveals that any two of the first electronic device, the second electronic device and the third electronic device trust each other, the account management server determines the distance between any two of the first electronic device, the second electronic device and the third electronic device according to the respective positioning information of the first electronic device, the second electronic device and the third electronic device; the account management server sends a response message to the first electronic device, wherein the response message comprises a judgment result, the distance between the first electronic device and the second electronic device, and the distance between the first electronic device and the third electronic device;

the account management server also sends a notification message to the second electronic device, wherein the notification message comprises a judgment result and a distance between the second electronic device and the third electronic device; after receiving the notification message, the second electronic device determines M2 types of data transmission modes to be selected for wireless communication between the second electronic device and the third electronic device in the manner described in the first embodiment; the second electronic device determines N2 available data transmission modes between the second electronic device and the third electronic device in the manner described in the first embodiment; then, the second electronic device sends a sharing message to the first electronic device, wherein the sharing message reveals N2 available data transmission modes of wireless communication between the second electronic device and the third electronic device, which are determined by the second electronic device; further, the second electronic device also sends a sharing message to the third electronic device;

alternatively, the first and second electrodes may be,

according to the distance between any two of the first electronic device, the second electronic device and the third electronic device, the account management server determines M1 candidate data transmission modes of wireless communication between the first electronic device and the second electronic device, M2 candidate data transmission modes of wireless communication between the second electronic device and the third electronic device, and M3 candidate data transmission modes of wireless communication between the first electronic device and the third electronic device; sending a response message to the first electronic device, wherein the response message comprises a judgment result, M1 types of data transmission modes to be selected and M3 types of data transmission modes to be selected; sending a notification message to the second electronic device, wherein the notification message comprises a judgment result and M2 types of data transmission modes to be selected; the second electronic device determines N2 available data transmission modes between the second electronic device and the third electronic device in the manner described in the first embodiment; then, the second electronic device sends a sharing message to the first electronic device, wherein the sharing message reveals N2 available data transmission modes of wireless communication between the second electronic device and the third electronic device, which are determined by the second electronic device;

the first electronic equipment receives a response message from the account management server, wherein the response message is a feedback message of the request message; if the response message reveals that any two of the first electronic device, the second electronic device, and the third electronic device are trusted to each other, then:

the first electronic device determines N1 available data transmission modes of wireless communication between the first electronic device and the second electronic device; the first electronic device receives a sharing message from the second electronic device, wherein the sharing message reveals N2 available data transmission modes of wireless communication between the second electronic device and the third electronic device, which are determined by the second electronic device; the first electronic device determines N3 available data transmission modes of wireless communication between the first electronic device and the third electronic device; the first electronic device automatically selects a data transmission mode with the highest priority from the N1 available data transmission modes, the N2 available data transmission modes and the N3 available data transmission modes, and transmits a file to the third electronic device in the data transmission mode with the highest priority; wherein M1, M2 and M3 are positive integers of 1 or more; n1 is a positive integer of M1 or less and 1 or more; n2 is a positive integer of M2 or less and 1 or more; n3 is a positive integer of M3 or less and 1 or more.

In this way, the first electronic device can establish a communication connection with the third electronic device via the second electronic device by means of short-range point-to-point transmission. Since the priority of the short-range point-to-point transmission mode is higher than that of the WLAN transmission mode, the data transmission mode between the first electronic device and the third electronic device is also selected to be the short-range point-to-point transmission mode, and the WLAN transmission mode is not selected.

In the case of four or more electronic devices, there may be a plurality of routing situations in the manner described above. Similar to the description in the fifth embodiment, regarding the selection of the specific route, at least one factor of the remaining power, the computing power, the available bandwidth, the security, the stability, and the like is synthesized, and the electronic device with the strongest synthetic capability is selected as the soft route, which is not described herein again.

In the case that no specific description is given, the related contents related to the seventh embodiment of the present application are the same as or similar to the related contents related to any of the foregoing embodiments of the present application, and are not described herein again. Those skilled in the art should understand that the parts in the seventh embodiment of the present application can be freely combined.

Example eight: more than three electronic devices are related to at most three modes of short-distance point-to-point transmission, WLAN transmission and cellular network transmission.

When more than three electronic devices are related to at most three modes, namely, near-distance point-to-point transmission, WLAN transmission and cellular network transmission, a data transmission mode is also selected between any two electronic devices according to the fourth embodiment. And will not be described in detail herein.

It should be noted that the determination as to whether a connection in a high-priority manner can be established between two electronic devices of the three or more electronic devices includes a direct connection and an indirect connection.

For clarity of illustration, three electronic devices are illustrated. For example, after the determination, the data transmission method between the first electronic device and the second electronic device is selected to be a short-range point-to-point transmission method, and the data transmission method between the second electronic device and the third electronic device is selected to be a short-range point-to-point transmission method. Optionally, the second electronic device sends a data transmission mode between the second electronic device and the third electronic device to the first electronic device.

In this way, the first electronic device can establish a communication connection with the third electronic device via the second electronic device by a short-distance point-to-point transmission mode. Since the priority of the short-range point-to-point transmission mode is higher than the priority of the WLAN transmission mode and the cellular network transmission mode, the data transmission mode selected between the first electronic device and the third electronic device is also the short-range point-to-point transmission mode, and neither the WLAN transmission mode nor the cellular network transmission mode is selected.

For another example, after the determination, the data transmission mode between the first electronic device and the second electronic device is selected to be a short-distance point-to-point transmission mode, and the data transmission mode between the second electronic device and the third electronic device is selected to be a WLAN transmission mode. Optionally, the second electronic device sends a data transmission mode between the second electronic device and the third electronic device to the first electronic device.

Therefore, when the first electronic equipment sends data to the third electronic equipment, the first electronic equipment sends the data to the second electronic equipment in a close-range point-to-point transmission mode; and then the second electronic equipment sends data to the third electronic equipment in a WLAN transmission mode. Because the priority of the short-distance point-to-point transmission mode is higher than that of the WLAN transmission mode, and the priority of the WLAN transmission mode is higher than that of the cellular network transmission mode, the data transmission mode between the first electronic device and the third electronic device is selected to be the short-distance point-to-point transmission mode + the WLAN transmission mode (namely, the short-distance point-to-point transmission mode is adopted between the first electronic device and the second electronic device, and the WLAN transmission mode is adopted between the second electronic device and the third electronic device), and the cellular network transmission mode is not selected.

In the case of four or more electronic devices, there may be a plurality of routing situations in the manner described above. Similar to the description in the fifth embodiment, regarding the selection of the specific route, various factors such as the remaining power, the computing power, the available bandwidth, and the like are integrated, and the electronic device with the strongest integrated capability is selected as the soft route, which is not described herein again. Those skilled in the art will recognize that the parts of embodiment eight can be freely combined. The eighth embodiment of the present application has no description, and reference may be made to the description related to the seventh embodiment, which is not repeated herein.

The data transmission modes related to the present application include but are not limited to: a close range point-to-point transmission mode, a WLAN transmission mode and a cellular network transmission mode. Each data transmission mode has a priority.

Illustratively, the close range point-to-point transmission mode has the highest priority, the WLAN transmission mode has the second priority, and the cellular network transmission mode has the lowest priority. The close-range point-to-point transmission mode is the most preferred data transmission mode, network resources of the electronic equipment can not be occupied in the data transmission process, and user experience is better.

The above prioritization of data transmission is merely illustrative. Other orderings are also possible in particular implementations. For example, the WLAN transmission method has the highest priority, the short-range point-to-point transmission method has the second priority, and the cellular network transmission method has the lowest priority. Any ordering of the priorities of the three data transmission modes is within the scope of the present application.

The priority of the data transmission method includes but is not limited to at least one of data transmission speed, cost, security, stability, etc.

Therefore, the data transmission mode with the highest priority is preferentially selected for data transmission during data transmission, and if service conflict or network bandwidth problems occur in the transmission process, the data transmission mode with the second priority can be switched to for data transmission, so that the data transmission efficiency can be guaranteed to be optimal.

For example, in any embodiment of the foregoing embodiments, after the data transmission method between the first electronic device and the second electronic device is selected to be the short-distance point-to-point transmission method, and after the file is transmitted to a certain proportion (for example, after the transmission is completed by 60%), at this time, the short-distance point-to-point transmission method is not available (due to some reason), the data transmission method between the first electronic device and the second electronic device is selected to be the transmission method with the highest priority in the data transmission methods to be selected at this time, for example, the WLAN transmission method, and the remaining part of the file after the certain proportion is continuously transmitted (for example, 40%).

Further, after the file is transmitted to another certain proportion (for example, 80% of the file is completely transmitted), the WLAN transmission mode is not available (for some reason), the data transmission mode between the first electronic device and the second electronic device is selected as the transmission mode with the highest priority in the data transmission modes to be selected at this time, for example, the cellular network transmission mode, and the remaining part (for example, 20%) of the file after the other certain proportion is continuously transmitted.

Optionally, after the file is transmitted to another certain proportion (for example, 80% of the file is transmitted), at this time, the short-distance point-to-point transmission mode is recovered to be available, the data transmission mode between the first electronic device and the second electronic device is selected as the transmission mode with the highest priority in the data transmission modes to be selected at this time, that is, the short-distance point-to-point transmission mode, and the remaining part (for example, 20%) of the file after the certain proportion is transmitted is continued.

A wireless data transmission method provided in the embodiments of the present application is described below. The two electronic devices are exemplified to be involved in at most short-distance point-to-point transmission and cellular network transmission. The two electronic devices include a first electronic device and a second electronic device. Those skilled in the art will appreciate that other approaches are similar.

Fig. 8 is a flowchart illustrating a method for wireless data transmission according to an embodiment of the present application. As shown in fig. 8, the wireless data transmission method includes the following steps:

s801: the first electronic device and the second electronic device send respective login accounts and device information to the account management server.

The login account can be a Hua account or an account of another manufacturer. The device information includes at least a device ID and location information (e.g., at least one of GPS coordinates, BDS coordinates, QZSS coordinates, SBAS coordinates, etc.).

S802: the first electronic equipment sends a request message to the account management server.

Specifically, after it is detected that the first electronic device transmits a file to the second electronic device, the first electronic device sends a request message to the account management server, where the request message is used to obtain a trust relationship between the first electronic device and the second electronic device.

S803: the account management server judges the trust relationship between the first electronic device and the second electronic device.

Specifically, the account management server determines whether login accounts of the first electronic device and the second electronic device are the same account or accounts of the same group. And judging whether the account management server belongs to the same account group stored in advance by the account management server through the received login accounts of the first electronic device and the second electronic device. The accounts of the same manufacturer and/or different manufacturers can form the same group. For example, three Huawei account numbers form the same group. For another example, a Huawei account, an account of manufacturer a and an account of manufacturer B form a same group. The manufacturer A and the manufacturer B are different from Hua.

S804: if the first electronic device and the second electronic device trust each other, the account management server determines the distance between the first electronic device and the second electronic device, and sends the judgment result of mutual trust and the distance to the first electronic device and the second electronic device.

The first electronic device preliminarily determines the distance between the first electronic device and the second electronic device according to the self positioning information and the positioning information of the second electronic device, because the device information includes the positioning information.

Alternatively, if the first electronic device and the second electronic device trust each other, the account management server sends the judgment result and the device information of the trust each other to the first electronic device and the second electronic device.

S805: and according to the distance, the first electronic equipment preliminarily determines a data transmission mode to be selected, which can be used for data transmission between the first electronic equipment and the second electronic equipment.

And the first electronic equipment preliminarily determines a data transmission mode which can carry out data transmission between the first electronic equipment and the second electronic equipment according to the distance, and judges through the relation between the distance and the first threshold. The first threshold is preset according to the characteristics of a short-distance point-to-point transmission mode (such as Bluetooth and Wi-Fi direct).
