Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Users sometimes need to transfer information between two devices, called a first device and a second device, respectively, which information is called information to be transferred.

In some embodiments, two devices may connect via bluetooth, wi-Fi, etc., which requires that both devices be online at the same time, e.g., both devices need to turn on bluetooth or connect to Wi-Fi.

However, bluetooth connection or Wi-Fi is susceptible to external interference, resulting in unstable connection between two devices, and when the two devices are disconnected due to signal instability or the like, information cannot be normally transmitted between the two devices, and the information cannot be retransmitted after the two devices resume connection. In addition, the physical distance between two devices can also affect the normal transmission of information. In addition, there is some complexity in establishing a bluetooth or Wi-Fi connection between two devices. Thus, the user experience is reduced.

The present disclosure is directed to providing an information transmission method, which has fewer transmission restrictions, and can use a cloud as an intermediate information processor and a message distributor, and the cloud can retransmit information to be transmitted that is not successfully transmitted, thereby eliminating the restriction that two devices must be online at the same time, and eliminating the restriction that a short distance between the two devices is maintained. In addition, when information transmission is needed, a user can simply operate on the first device, operation steps are simpler and more convenient, and therefore user experience is improved.

The information transmission method provided by the disclosure is suitable for a scene of mutually transmitting information between two devices, for example, the scene can comprise mutually transmitting target geographic position information between mobile phone navigation software and vehicle-mounted system navigation software. In actual operation, the user can send the selected target address position information in the mobile phone navigation software to the navigation software of the vehicle-mounted system, and can also send the target address position information in the navigation software of the vehicle-mounted system to the mobile phone navigation software.

The technical solutions provided by the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments.

The first device and the second device may be respectively installed with target software, and the target software may be navigation software.

Fig. 2 is a schematic flow chart of an information transmission method according to an embodiment of the present disclosure.

As shown in fig. 2, the information transmission method 200 may be performed by a cloud, and the information transmission method 200 may include operations S210 to S240.

In operation S210, information to be transmitted from a first device is acquired, the information to be transmitted including a second device identification of a second device associated with the first device.

The information to be transmitted may also include target information, which may represent information that needs to be transmitted between the first device and the second device. For example, the first device and the second device may be respectively installed with navigation software, and the target information may be target geographical location information. For another example, the first device and the second device may be respectively installed with audio playing software, and the target information may be audio information. For another example, the first device and the second device may be respectively installed with image software, and the target information may be image information. The present embodiment does not limit the target information.

For example, the first device may send the information to be transmitted through an https request, and security may be improved by using https network transmission.

In operation S220, it is determined whether the second device is in an online state according to the second device identification.

For example, in the case where a device has established a connection with the cloud, the cloud may add the identity of the device to the set of identities. Under the condition that the equipment and the cloud end are disconnected, the cloud end can delete the equipment identifier from the identifier set. After receiving the information to be transmitted, the cloud can detect whether the second equipment identifier is included in the identifier set, if so, the cloud determines that the second equipment is in an online state, and if not, the cloud determines that the second equipment is in an offline state.

In operation S230, in case it is determined that the second device is in an offline state, information to be transmitted is added to the message queue.

For example, the message queue may be a Kafka message queue.

In response to detecting that the second device is switched from the offline state to the online state, information to be transmitted in the message queue is transmitted to the second device in operation S240.

For example, the cloud end may refer to the above for detecting whether the second device is in an online state, which is not described herein.

According to the technical scheme provided by the embodiment of the disclosure, when the second equipment is in an offline state, the cloud end can store the information to be transmitted to the message queue first and send the information to the second equipment when the second equipment is in an online state, so that the first equipment and the second equipment are not required to be online at the same time, and the physical distance between the first equipment and the second equipment has no influence on the information to be transmitted, thereby improving user experience.

Fig. 3 is a schematic flow chart of an information transmission method according to an embodiment of the present disclosure.

As shown in fig. 3, the information transmission method 300 may be performed by an information transmission system including a first device, a cloud, and a second device. The information transmission method 300 may include operations S310 to S360.

In operation S310, the first device sends information to be transmitted to the cloud.

In operation S320, the cloud end determines whether the second device is in an online state according to the second device identifier in response to receiving the information to be transmitted from the first device. If the operation is in the on-line state, the operation proceeds to operation S330, and if the operation is in the off-line state, the operation proceeds to operation S340.

For example, in the case where a device has established a connection with the cloud, the cloud adds the identity of the device to the set of identities. And under the condition that the equipment is disconnected from the cloud end, the cloud end deletes the equipment identifier from the identifier set. After receiving the information to be transmitted, the cloud can detect whether the second equipment identifier is included in the identifier set, if so, the cloud determines that the second equipment is in an online state, and if not, the cloud determines that the second equipment is in an offline state.

For another example, the cloud end and the second device may maintain heartbeat connection, if the heartbeat connection between the cloud end and the second device is disconnected, it is determined that the second device is in an offline state, otherwise, it is determined that the second device is in an online state.

In operation S330, the cloud end sends information to be transmitted to the second device.

In operation S340, the cloud end adds the information to be transmitted to the message queue.

In operation S350, the cloud end sends information to be transmitted in the message queue to the second device in response to detecting that the second device is switched from the offline state to the online state.

In operation S360, the second device receives the information to be transmitted from the cloud.

According to the technical scheme provided by the embodiment of the disclosure, when the second equipment is in an offline state, the cloud end can store information to be transmitted to the message queue first and send the information to the second equipment when the second equipment is in an online state, so that the first equipment and the second equipment do not need to be online at the same time, and the physical distance between the first equipment and the second equipment has no influence on the information to be transmitted, thereby improving user experience.

According to another embodiment of the present disclosure, the above information transmission method may further include the following operations: and the cloud end deletes the information to be transmitted from the message queue in response to detecting that the storage time length of the information to be transmitted in the message queue is greater than or equal to the preset push time length.

In this embodiment, the user may set a predetermined pushing duration through the first device, and if the duration of the information to be transmitted in the cloud exceeds the predetermined pushing duration, the user may not push the information to be transmitted any more, so as to avoid pushing the expired information to be transmitted to the second device.

It should be noted that, when the cloud end can clear the information to be transmitted according to the predetermined pushing duration, the cloud end can send the information to be transmitted in the message queue to the second device when detecting that the second device is switched from the offline state to the online state and the information to be transmitted is not deleted from the message queue.

Fig. 4 is a schematic diagram of a method of updating a database according to an embodiment of the present disclosure.

As shown in fig. 4, in this embodiment, a record corresponding to the information to be transmitted may also be stored in the database, and the database may be updated according to the actual situation, and the process of updating the database will be described below.

For example, the first device 401 sends information to be transmitted to the cloud 402. In response to receiving the information to be transmitted, the cloud 402 stores a record corresponding to the information to be transmitted in a database.

When the user needs to query the record, the user can operate on the first device 401, and the first device 401 sends a query instruction to the cloud 402. In response to receiving the query instruction from the first device 401, the cloud 402 outputs, to the first device 401, the remaining records in the database and a transmission state of information to be transmitted corresponding to each remaining record, where the transmission state may include transmitted and untransmitted.

The first device 401 presents the remaining records and transmission status to the user in response to receiving the remaining records and transmission status from the cloud 402. The user may click on the first device 401 to undo a target remaining record, which may trigger a cancel instruction.

The first device 401 sends a delete instruction for the target remaining record to the cloud 402 in response to receiving a cancel instruction for the target remaining record. Next, in response to receiving a deletion instruction for the target remaining record, the cloud 402 may determine whether the information to be transmitted is in the message queue, if so, may delete the information to be transmitted corresponding to the target remaining record from the message queue, and if not, may return a result to the user.

In this embodiment, the user may query the navigation software of the first device 401 for the sending record, and the cloud 402 returns the remaining records that are not deleted in the database to the first device 401. If the information to be transmitted is not successfully transmitted and is still in the message queue of the cloud 402, the user can cancel the request for transmitting the information to be transmitted, so that the flexibility of use is improved.

In other examples, records in the database may also be deleted in other ways. For example, the user may set a predetermined clearing duration on the navigation software of the first device or the second device, the cloud may traverse the remaining records in the database according to the received instruction or periodically, determine whether the storage duration of each record in the database is greater than or equal to the predetermined clearing duration, if so, delete the record from the database, and if not, continue to reserve the record. In this embodiment, the cloud may run a script, and clear the sending record of the information to be transmitted at regular time according to the preset clear duration set by the user, so as to improve the security of the user information.

Fig. 5A is a schematic flowchart of an information transmission method according to an embodiment of the present disclosure, and fig. 5B is a schematic diagram of an information transmission method according to an embodiment of the present disclosure.

As shown in fig. 5A and 5B, in the present embodiment, the information transmission method 500 may include operations S511 to S512, and operations S520 to S580.

Before performing operation S511, some preprocessing operations may be performed in advance. For example, an asymmetric encrypted key pair may be generated in advance using the RSA algorithm, and the key pair may include a first key and a second key, where it can be seen that one of the first key and the second key is a public key, and the other is a private key. The first device 501 and the second device 503 may then store the first key and the second key, respectively.

In use, the first device 501 may take the geographic location of the first device 501 at the current time as target geographic location information, or take the geographic location selected by the user in the navigation software of the first device 501 as target geographic location information. The user may also configure the values of the predetermined push time period and the predetermined clear time period in the first device 501. Next, operation S511 may be performed.

In operation S511, the first device 501 performs encryption processing.

For example, the first device 501 generates a symmetric key using a symmetric encryption algorithm, which may be an AES algorithm. The first device 501 then encrypts the target geographic location information using the symmetric key to obtain encrypted information. The first device 501 further encrypts the symmetric key by using the first key in the key pair to obtain an encrypted symmetric key. The first device 501 then determines information to be transmitted according to the encrypted information, the encrypted symmetric key, and the second device 503 identifier, for example, splices the encrypted information and the encrypted symmetric key, and combines the spliced character string with the second device 503 identifier to form the information to be transmitted.

The embodiment encrypts the information to be transmitted by using the symmetric key and the secret key, so that the information to be transmitted can be prevented from being leaked, and the safety is improved. In addition, the embodiment also utilizes the symmetric encryption algorithm to randomly generate the symmetric key, so that the security of the symmetric key can be improved, and the security of information to be transmitted is further improved.

In operation S512, the first device 501 sends information to be transmitted to the cloud 502.

In operation S520, the cloud 502 determines whether the second device 503 is in an online state according to the identification of the second device 503 in response to receiving the information to be transmitted from the first device 501. If the operation is in the on-line state, the operation proceeds to operation S530, and if the operation is in the off-line state, the operation proceeds to operation S540.

In operation S530, the cloud 502 sends information to be transmitted to the second device 503.

In operation S540, the cloud 502 adds the information to be transmitted to the message queue.

In operation S550, the cloud 502 sends the information to be transmitted in the message queue to the second device 503 in response to detecting that the second device 503 is switched from the offline state to the online state.

In operation S560, the second device 503 receives the information to be transmitted from the cloud 502.

In operation S570, the second device 503 determines target geographical location information according to the information to be transmitted.

For example, the first device 501 performs encryption processing using a symmetric key and a key pair, and accordingly, the second device 503 decrypts the encrypted symmetric key using a second key in the key pair to obtain a symmetric key, and then the second device 503 decrypts the encrypted information using the symmetric key to obtain the target geographical location information.

In operation S580, the second device 503 performs navigation based on the target geographical location information.

For example, the navigation software of the second device 503 presents that the target geographic location information is received and asks the user whether to initiate navigation, and in response to the user clicking to initiate navigation, the navigation software of the second device 503 may initiate navigation.

It should be noted that, in addition to the above-described manner of performing encryption and decryption processing using the symmetric key and the key pair, other manners of encryption and decryption may be adopted. For example, the first device and the second device may agree in advance on a predetermined encryption algorithm and a predetermined decryption algorithm, where the first device encrypts the information to be transmitted according to the predetermined encryption algorithm, and the second device decrypts the information according to the predetermined decryption algorithm, thereby obtaining the target geographic location information.

It should be noted that in some embodiments, the operations of encrypting and decoding may be omitted, for example, the first device does not encrypt the target geographic location information to encrypt, but directly sends the information to be transmitted, which is not encrypted, to the cloud end, and after the second device obtains the information to be transmitted from the cloud end, the second device may directly extract the sub-information of the predetermined field from the information to be transmitted, as the target geographic location information.
