In the information transmission method provided by the embodiment of the application, the execution subject may be an information transmission device, the information transmission device may be a first information transmission device, or the execution subject may be a first network device, or the execution subject may be a functional module or entity in the first network device. In the embodiment of the present application, an information transmission method performed by a first network device is taken as an example, and the information transmission method provided in the embodiment of the present application is described.

Fig. 2 shows a flowchart of an information transmission method according to an embodiment of the present application. As shown in fig. 2, the information transmission method provided in the embodiment of the present application may include the following steps 101 and 102.

Step 101, under the condition that the first network device receives target information sent by the first electronic device, the first network device sends the target information to the second electronic device through a ground network.

In the embodiment of the present application, the first electronic device may be a transmitting device, and the second electronic device may be a receiving device.

In some embodiments of the present application, the target information may include at least one of: short messages, multimedia messages, etc.

In some embodiments of the present application, the above ground network may specifically be at least one of the following: a 3G network, a 4G network, a long term evolution technology (Long Term Evolution, LTE) network, a 5G network, etc.

In some embodiments of the present application, when the first electronic device sends the target information to the second electronic device, the first electronic device may send the target information to the first network device, so that the first network device may receive the target information, so that the first network device may store the cache information corresponding to the target information in a first cache area of the first network device, and add a first information identifier corresponding to the target information in a first information sending queue of the first network device, where the first information sending queue is a queue for sending information through a ground network, so that the first network device may send information sequentially through the ground network according to a queue order of the information in the first information sending queue, and when sending the target information through the ground network, the first network device may first obtain the cache information corresponding to the target information from the first cache area, so as to obtain the target information, and send the target information to the second electronic device through the ground network.

Optionally, the first information identifier may include at least one of: an equipment Identity (ID) of the first electronic equipment, a first information ID of the target information; the first information ID may be a unique ID set by the first network device for the target information.

Step 102, if the first network device does not receive a first Acknowledgement (ACK) message sent by the second electronic device within a first preset duration, the first network device sends a first request message to the second network device.

In some embodiments of the present application, the first preset duration may be a preset duration, or a duration agreed by a protocol.

In the embodiment of the present application, the first ACK message is used to indicate that the second electronic device receives the target information through the ground network.

In the embodiment of the present application, the first request message carries target information, and the first request message is used for requesting the second network device to send the target information to the second electronic device through the satellite network.

It can be understood that, because the second electronic device sends the first ACK message to the first network device when receiving the target information through the ground network, if the first network device does not receive the first ACK message sent by the second electronic device within the first preset duration, the second electronic device may be considered to not receive the target information through the ground network, that is, the second electronic device may be considered to be located outside the coverage area of the ground network, so that the first network device may request the second network device to send the target information to the second electronic device through the satellite network with a larger coverage area.

In some embodiments of the present application, after the first network device sends the first request message to the second network device, the second network device may store the cache information corresponding to the target information in a second cache area of the second network device, and add a second information identifier corresponding to the target information in a second information sending queue of the second network device, where the second information sending queue is a queue for sending information through the satellite network, so that the second network device may send information sequentially through the satellite network according to a queue order of the information in the second information sending queue, and when sending the target information through the satellite network, the second network device may first obtain the cache information corresponding to the target information from the second cache area, so as to obtain the target information, and then send the target information to the second electronic device through the satellite network.

Optionally, the second information identifier may include at least one of: a device identification (Identity, ID) of the first electronic device, a second information ID of the target information; the second information ID may be a unique ID set by the second network device for the target information.

It can be understood that, because the coverage area of the satellite network is larger than that of the ground network, the second electronic device has a larger probability of being within the network coverage area of the satellite network, and therefore, compared with the first network device sending the target information to the second electronic device through the ground network, after the second network device sends the target information to the second electronic device through the satellite network, the second electronic device can receive the target information through the satellite network, so that the success rate of receiving the target information by the second electronic device can be improved.

Optionally, when the target information is sent through the satellite network, the second network device may determine the target satellite first, and then control the target satellite to establish a connection with the second electronic device, so as to send the target information to the second electronic device through the target satellite.

The second network device may determine, according to a position where the second electronic device acquired by the second network device is located recently, a satellite closest to the position as a target satellite, so that the second network device may control the target satellite to establish connection with the second electronic device.

It should be noted that, for the description of how the second network device determines the satellite closest to the location where the second electronic device is located, reference may be made to the specific description in the related art, and the embodiments of the present application are not repeated herein.

In some embodiments of the present application, when the first network device receives the first ACK message sent by the second electronic device within the first preset duration, the first network device may directly delete the cache information corresponding to the target information from the first cache area, so as to save the storage space of the first network device.

It can be understood that if the first network device receives the first ACK message sent by the second electronic device within the first preset duration, the second electronic device may be considered to have successfully received the target information, that is, it may be considered that the target information may not need to be resent through the ground network later, so that the first network device may delete the cache information corresponding to the target information.

Of course, in order to further improve the success rate of receiving the target information by the second electronic device, when the first network device determines that the second electronic device does not receive the target information through the satellite network, the first network device may further instruct the first electronic device to resend the target information, which specifically includes the following steps:

in some embodiments of the present application, as shown in fig. 3 in conjunction with fig. 2, after the step 102, the information transmission method provided in the embodiment of the present application may further include the following steps 201 and 202.

Step 201, the first network device receives a first indication message sent by the second network device.

In the embodiment of the present application, the first indication message is used to indicate that the second network device does not receive the second ACK message sent by the second electronic device, where the second ACK message is used to indicate that the second electronic device receives the target information through the satellite network.

In some embodiments of the present application, after the second network device sends the target information to the second electronic device through the satellite network, the second network device may send the first indication message to the first network device if the second ACK message sent by the second electronic device is not received within the third preset time period, so that the first network device may receive the first indication message.

It can be understood that, because the second electronic device sends the second ACK message to the second network device when receiving the target information through the satellite network, if the second network device does not receive the second ACK message sent by the second electronic device within the third preset duration, the second electronic device may be considered to not receive the target information through the satellite network, that is, the second electronic device may be considered to be located outside the coverage area of the satellite network, so that the second network device may send the first indication information to the first network device, so that the first network device may instruct the first electronic device to resend the target information.

Optionally, the third preset duration may be a preset duration, or a duration agreed by a protocol.

Optionally, when the second network device does not receive the second ACK message sent by the second electronic device within the third preset duration, the second network device may further delete the cache information corresponding to the target information from the second cache area, so as to save a storage space of the second network device.

In some embodiments of the present application, when the first network device receives the first indication message, the first network device may further delete the cache information corresponding to the target information from the first cache area, so as to save a storage space of the first network device.

Step 202, the first network device sends a second indication message to the first electronic device.

In the embodiment of the present application, the second instruction message is used to instruct the first electronic device to execute the retransmission operation of the target information.

In some embodiments of the present application, the first network device may send the second indication message to the first electronic device after a fourth preset time period from the time the first indication message is received. The fourth preset duration may be a preset duration or a duration agreed by a protocol.

It can be understood that, because the second electronic device may move to the coverage area of the ground network again after a period of time, the first network device may wait for the fourth preset duration before sending the second indication message to the first electronic device when receiving the first indication message, so as to reduce the probability that the second electronic device is still located outside the coverage area of the ground network when the first electronic device performs the retransmission operation of the target information.

In some embodiments of the present application, the second indication message may specifically instruct the first electronic device to send the target information again after a fifth preset time period from receiving the second indication message. The fifth preset duration may be a preset duration or a duration agreed by the protocol.

In some embodiments of the present application, after the first electronic device re-transmits the target information to the first network device, the first network device may perform the above-described steps 101 and 102 again to transmit the target information to the second electronic device.

As can be seen, after the first network device determines that the second electronic device is located outside the coverage area of the satellite network, there is a greater possibility that the second electronic device moves to be within the coverage area of either the terrestrial network of the first network device or the satellite network of the second network device, so that the first network device can instruct the first electronic device to resend the target information, so as to trigger the first network device to execute the steps again, so that the second electronic device is more likely to receive the target information, and the success rate of receiving the information by the second electronic device can be further improved.

The embodiment of the application provides an information transmission method, in which when a first network device receives target information sent by a first electronic device, the first network device can firstly send the target information to a second electronic device through a ground network, and then when a first ACK message sent by the second electronic device and used for indicating that the second electronic device receives the target information through the ground network is not received within a first preset time period, a first request message carrying the target information is sent to the second network device, so that the second network device requests to send the target information to the second electronic device through a satellite network, and the second network device can send the target information to the second electronic device through the satellite network. The first network device may send the target information to the second electronic device through the ground network, and then in a case that the first ACK message is not received in the first preset period of time, that is, in a case that the second electronic device does not receive the target information, that is, in a case that the second electronic device is located outside the coverage area of the ground network of the first network device, the second network device is requested to send the target information to the second electronic device through the satellite network, and the coverage area of the satellite network of the second network device is larger than the coverage area of the ground network of the first network device, so that the probability that the second electronic device is located outside the coverage area of the satellite network of the second network device can be reduced, and the probability that the second electronic device cannot receive the target information after the second electronic device sends the target information to the second electronic device through the satellite network can be reduced.

And, in comparison with the related art, in the case where it is determined that the second electronic device does not successfully receive the target information through the terrestrial network, the first network device may directly request the second network device to transmit the target information to the second electronic device through the satellite network, without waiting for a long time and then transmitting the target information to the second electronic device through the terrestrial network again, so that the time delay for transmitting the information may be reduced.

Of course, in order to save the storage space of the first network device, the first network device may further delete the cache information corresponding to the target information, and the specific scheme is as follows:

in a possible implementation manner of the present application, as shown in fig. 2 and fig. 4, after the step 102, the information transmission method provided in the embodiment of the present application may further include the following steps 301 and 302.

Step 301, the first network device receives a third indication message sent by the second network device.

In the embodiment of the present application, the third indication message is used to indicate that the second network device receives a second ACK message sent by the second electronic device, where the second ACK message is used to indicate that the second electronic device receives the target information through the satellite network.

In some embodiments of the present application, when the second network device receives the second ACK message sent by the second electronic device, the second network device may delete the cache information corresponding to the target information first, and then send a third indication message to the first network device, so that the first network device may receive the third indication message.

Optionally, the second network device may delete the cache information corresponding to the target information from the second cache area, and then send a third indication message to the first network device.

It may be understood that if the second network device receives the second ACK message sent by the second electronic device, the second electronic device may be considered to have successfully received the target information, that is, it may be considered that the target information may not need to be resent through the satellite network and the terrestrial network later, so the second network device may delete the cache information corresponding to the target information, and send a third indication message to the first network device to indicate that the first network device also deletes the cache information corresponding to the target information.

Step 302, the first network device deletes the cache information corresponding to the target information according to the third indication message.

In some embodiments of the present application, the first network device may delete the cache information corresponding to the target information from the first cache area.

Therefore, the first network device can delete the cache information corresponding to the target information according to the indication of the second network device under the condition that the second electronic device receives the target information through the satellite network, so that the situation that the first network device still stores the cache information corresponding to the target information under the condition that the second electronic device does not need to send the target information again can be avoided, and therefore the storage space of the first network device can be saved.

In another possible implementation manner of the present application, as shown in fig. 5 in conjunction with fig. 2, after the step 102, the information transmission method provided by the embodiment of the present application may further include a step 401 described below.

Step 401, in a second preset duration from a time when the second network device sends the target information to the second electronic device through the satellite network, if the first network device receives the first ACK message sent by the second electronic device, the first network device sends a fourth indication message to the second network device.

In the embodiment of the present application, the fourth indication message is used to indicate that the first network device receives the first ACK message sent by the second electronic device, where the fourth indication message is used to control the second network device to delete the cache information corresponding to the target information.

In some embodiments of the present application, the second preset duration may be a preset duration, or a duration agreed by a protocol.

It can be appreciated that, because the situation that the ground network of the first network device is blocked may occur, and thus the situation that the second electronic device has successfully received the target information may occur, and the first network device needs a long time to receive the first ACK message sent by the second electronic device, the first network device may instruct the second network device to delete the cache information corresponding to the target information in a second preset period from the moment that the second network device sends the target information to the second electronic device through the satellite network, under the condition that the first ACK message sent by the second electronic device is received.

In some embodiments of the present application, when the first network device receives the first ACK message sent by the second electronic device, the first network device may further delete the cache information corresponding to the target information from the first cache area.

In some embodiments of the present application, when the second network device receives the fourth indication message, the second network device may delete the cache information corresponding to the target information from the second cache area, and delete the second information identifier corresponding to the target information from the second information transmission queue.

It can be understood that, because the second electronic device has successfully received the target information, the second network device may not need to send the target information to the second electronic device through the satellite network, so that the second network device may delete the cache information corresponding to the target information from the second cache area, so as to save the storage space of the second network device, and delete the second information identifier from the second information sending queue, so as to avoid the second network device from sending the target information.

Therefore, the first network device can also instruct the second network device to delete the cache information corresponding to the target information under the condition that the second electronic device successfully receives the target information, so that the situation that the second network device still stores the cache information corresponding to the target information under the condition that the second electronic device does not need to send the target information again can be avoided, and the storage space of the second network device can be saved.

According to the information transmission method provided by the embodiment of the application, the execution main body can be an information transmission device, and the information transmission device is a first information transmission device. In the embodiment of the present application, an information transmission method performed by an information transmission device is taken as an example, and the information transmission device provided in the embodiment of the present application is described.

Fig. 6 shows a schematic diagram of a possible configuration of an information transmission device, which is a first information transmission device, according to an embodiment of the present application. As shown in fig. 6, the first information transmission apparatus 40 may include: a transmission module 41, configured to, when the first information transmission device receives the target information sent by the first electronic device, send the target information to the second electronic device through the ground network; and under the condition that the first information transmission device does not receive the first ACK message sent by the second electronic equipment within the first preset time period, sending a first request message to the second information transmission device, wherein the first request message carries target information, and the first request message is used for requesting the second information transmission device to send the target information to the second electronic equipment through a satellite network. The first ACK message is used for indicating that the second electronic device receives the target information through the ground network.

The embodiment of the application provides an information transmission device, which is a first information transmission device, and because the first information transmission device can firstly send target information to a second electronic device through a ground network, then in the case that a first ACK message is not received in a first preset time period, that is, in the case that the second electronic device does not receive the target information, that is, in the case that the second electronic device is located outside the coverage area of the ground network of the first information transmission device, the second information transmission device is requested to send the target information to the second electronic device through a satellite network, and the coverage area of the satellite network of the second information transmission device is larger than the coverage area of the ground network of the first information transmission device, the probability that the second electronic device is located outside the coverage area of the satellite network of the second information transmission device can be reduced, and therefore the probability that the second electronic device cannot receive the target information after the second information transmission device sends the target information to the second electronic device through the satellite network can be reduced, and the success rate of the second electronic device receiving the target information can be improved.

In a possible implementation manner, the transmission module 41 is further configured to receive, after sending the first request message to the second information transmission device, a first indication message sent by the second information transmission device, where the first indication message is used to indicate that the second information transmission device does not receive a second ACK message sent by the second electronic device, and the second ACK message is used to indicate that the second electronic device receives the target information through the satellite network; and transmitting a second indication message to the first electronic device, where the second indication message is used to instruct the first electronic device to perform a retransmission operation of the target information.

In a possible implementation manner, the transmission module 41 is further configured to receive, after sending the first request message to the second information transmission device, a third indication message sent by the second information transmission device, where the third indication message is used to indicate that the second information transmission device receives a second ACK message sent by the second electronic device, and the second ACK message is used to indicate that the second electronic device receives the target information through the satellite network. The first information transmitting apparatus 40 provided in the embodiment of the present application may further include: and a deleting module, configured to delete the cache information corresponding to the target information according to the third indication message received by the transmitting module 41.

In a possible implementation manner, the transmission module 41 is further configured to, after sending the first request message to the second information transmission device, send, in a second preset period from a time when the second information transmission device sends the target information to the second electronic device through the satellite network, a fourth indication message to the second information transmission device when the first information transmission device receives the first ACK message sent by the second electronic device, where the fourth indication message is used to instruct the first information transmission device to receive the first ACK message sent by the second electronic device, and the fourth indication message is used to control the second information transmission device to delete the cache information corresponding to the target information.

As can be seen from this, on the one hand, after the first network device determines that the second electronic device is located outside the coverage area of the satellite network, there is a greater possibility that the second electronic device moves to be within the coverage area of either the terrestrial network of the first network device or the satellite network of the second network device, so that the first network device may instruct the first electronic device to resend the target information, so as to trigger the first network device to execute the above steps again, so that the second electronic device is more likely to receive the target information, and therefore, the success rate of receiving the information by the second electronic device may be further improved; on the other hand, under the condition that the second electronic equipment receives the target information through the satellite network, the first network equipment deletes the cache information corresponding to the target information according to the indication of the second network equipment, so that the situation that the first network equipment still stores the cache information corresponding to the target information under the condition that the second electronic equipment does not need to send the target information again can be avoided, and therefore the storage space of the first network equipment can be saved; on the other hand, under the condition that the second electronic device has successfully received the target information, the first network device can also instruct the second network device to delete the cache information corresponding to the target information, so that the situation that the second network device still stores the cache information corresponding to the target information under the condition that the second electronic device does not need to send the target information again can be avoided, and the storage space of the second network device can be saved.
