Step 101: When the first network device receives the target information sent by the first electronic device, the first network device sends the target information to the second electronic device through the ground network.

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

In some embodiments of the present application, the above-mentioned target information may include at least one of the following: short message, multimedia message, etc.

In some embodiments of the present application, the above-mentioned terrestrial network may be at least one of the following: a 3G network, a 4G network, a 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 can send the target information to the first network device, so that the first network device can receive The target information, so that the first network device can store the cache information corresponding to the target information in the first cache area of the first network device, and add the third information corresponding to the target information to the first information sending queue of the first network device. An information identifier, the first information sending queue is a queue for sending information through the ground network, so that the first network device can send information through the ground network in sequence according to the queue order of the information in the first information sending queue, and then through the ground network When sending target information, the first network device may first obtain the cache information corresponding to the target information from the first cache area to obtain the target information, and then send the target information to the second electronic device through the ground network.

Optionally, the above-mentioned first information identification may include at least one of the following: a device identification (Identity, ID) of the first electronic device, a first information ID of the target information; wherein the first information ID may be the first network device Unique ID set for the target information.

Step 102: If the first network device does not receive the first acknowledgment (ACK) message sent by the second electronic device within the first preset time period, the first network device sends a first request to the second network device. information.

In some embodiments of the present application, the above-mentioned first preset duration may be a preconfigured duration or a duration agreed upon in an agreement.

In this embodiment of the present application, the above-mentioned first ACK message is used to indicate that the second electronic device has received the target information through the ground network.

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

It can be understood that since the second electronic device will send the first ACK message to the first network device when receiving the target information through the ground network, therefore, if the first network device does not receive the first ACK message within the first preset time period, If the first ACK message is sent by the second electronic device, it can be considered that the second electronic device has not received the target information through the ground network, that is, it can be considered that the second electronic device may be outside the coverage of the ground network, so the first network device can request the third The second network device sends the target information to the second electronic device through a 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 the second cache area of the second network device. , and add the second information identifier corresponding to the target information in the second information sending queue of the second network device. The second information sending queue is a queue for sending information through the satellite network, so that the second network device can follow the second information sending queue. The queue sequence of the information in the information sending queue is to send the information through the satellite network in sequence, and when sending the target information through the satellite network, the second network device can first obtain the cache information corresponding to the target information from the second cache area to obtain the target information. , and then send the target information to the second electronic device through the satellite network.

Optionally, the above-mentioned second information identification may include at least one of the following: a device identification (Identity, ID) of the first electronic device, a second information ID of the target information; wherein the second information ID may be a second network device Unique ID set for the target information.

It can be understood that since the coverage area of the satellite network is greater than the coverage area of the terrestrial network, there is a higher probability that the second electronic device will be within the network coverage area of the satellite network. Therefore, compared with the first network device transmitting data to the second electronic device through the terrestrial network, For the electronic device to send the target information, after the second network device sends the target information to the second electronic device through the satellite network, the second electronic device will have a high probability of receiving the target information through the satellite network. In this way, the second electronic device can be improved. The success rate of electronic devices in receiving target information.

Optionally, when sending the target information through the satellite network, the second network device can first determine the target satellite, 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. target information.

Wherein, the second network device can determine the satellite closest to the position as the target satellite according to the recent position of the second electronic device obtained by the second network device, so that the second network device can control the target satellite and the second The electronic device establishes a connection.

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

In some embodiments of the present application, in the case where the first network device receives the first ACK message sent by the second electronic device within the first preset time period, the first network device may directly obtain the first ACK message from the first cache area. Delete cache information corresponding to the target information to save 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 time period, it can be considered that the second electronic device has successfully received the target information, that is, it can be considered that there may be no need to pass the subsequent The ground network resends the target information. Therefore, the first network device can delete the cache information corresponding to the target information.

Of course, in order to further improve the success rate of the second electronic device receiving the target information, when the first network device determines that the second electronic device has not received the target information through the satellite network, the first network device can also instruct the first electronic device to re- To send the target information, the specific plan is as follows:

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

Step 201: The first network device receives the first instruction message sent by the second network device.

In the embodiment of the present application, the above-mentioned first indication message is used to indicate that the second network device has not received the second ACK message sent by the second electronic device, and the second ACK message is used to indicate that the second electronic device has received the target through the satellite network. information.

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 not receive the third message sent by the second electronic device within a third preset time period. In the case of an ACK message, the first indication message is sent to the first network device, so that the first network device can receive the first indication message.

It can be understood that since the second electronic device will send the second ACK message to the second network device when receiving the target information through the satellite network, therefore, if the second network device does not receive the third ACK message within the third preset time period, If the second ACK message is sent by the second electronic device, it can be considered that the second electronic device has not received the target information through the satellite network, that is, it can be considered that the second electronic device may also be located outside the coverage of the satellite network, so that the second network device can The first network device sends the first instruction information, so that the first network device can instruct the first electronic device to resend the target information.

Optionally, the third preset duration may be a preconfigured duration or a duration agreed upon in an agreement.

Optionally, if the second network device does not receive the second ACK message sent by the second electronic device within the third preset time period, the second network device may also delete the cache information corresponding to the target information from the above-mentioned second cache area, so as to Save storage space on 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 also delete the cache information corresponding to the target information from the first cache area to save the first network device. The storage space of the device.

Step 202: The first network device sends a second instruction message to the first electronic device.

In this embodiment of the present application, the above-mentioned second instruction message is used to instruct the first electronic device to perform a resending 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 moment when the first indication message is received. The fourth preset duration may be a preconfigured duration or a duration agreed upon in the agreement.

It can be understood that since the second electronic device may move to the coverage of the terrestrial network again after a period of time, the first network device may first wait for the fourth electronic device after receiving the first instruction message. A second instruction message is sent to the first electronic device for a preset period of time to reduce the probability that the second electronic device is still outside the coverage of the ground network when the first electronic device performs a retransmission operation of the target information.

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

In some embodiments of the present application, after the first electronic device re-sends the target information to the first network device, the first network device can perform the above-mentioned steps 101 and 102 again to send the target information to the second electronic device. .

It can be seen from this that after the first network device determines that the second electronic device is outside the coverage of the satellite network, it is more likely that the second electronic device will move to the terrestrial network of the first network device and the satellite network of the second network device. situation within the coverage of any network, in this way, the first network device can instruct the first electronic device to resend the target information to trigger the first network device to perform the above steps again, so that the second electronic device is more likely to receive Therefore, the success rate of the second electronic device in receiving the information can be further improved.

Embodiments of the present application provide an information transmission method. When the first network device receives target information sent by the first electronic device, the first network device can first send the target information to the second electronic device through the ground network, and then If the first ACK message sent by the second electronic device to indicate that the second electronic device has received the target information through the ground network is not received within the first preset time period, send an ACK message carrying the target information to the second network device. The first request message is to request the second network device to send the target information to the second electronic device through the satellite network, so that the second network device can send the target information to the second electronic device through the satellite network. Since the first network device can first send the target information to the second electronic device through the ground network, and then does not receive the first ACK message within the first preset time period, that is, when the second electronic device does not receive the target information, In the case of information, that is, when the second electronic device is located outside the coverage of the terrestrial 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 second network The coverage of the satellite network of the device is greater than the coverage of the terrestrial network of the first network device. Therefore, the probability that the second electronic device is also located outside the coverage of the satellite network of the second network device can be reduced, thereby reducing After the second network device sends the target information to the second electronic device through the satellite network, there is a probability that the second electronic device cannot receive the target information. In this way, the success rate of the second electronic device receiving the information can be improved.

Moreover, compared with related technologies, when it is determined that the second electronic device has not successfully received the target information through the terrestrial network, the first network device can directly request the second network device to send the target information to the second electronic device through the satellite network. This target information does not need to wait for a long time before sending the target information to the second electronic device through the ground network again. Therefore, the delay in sending the information can be reduced.

Of course, in order to save the storage space of the first network device, the first network device can also delete the cache information corresponding to the target information. The specific solution is as follows:

In a possible implementation of the present application, as shown in Figure 4 in conjunction with Figure 2, after the above step 102, the information transmission method provided by the embodiment of the present application may further include the following steps 301 and 302.

Step 301: The first network device receives the third instruction message sent by the second network device.

In this embodiment of the present application, the above-mentioned third indication message is used to indicate that the second network device has received the second ACK message sent by the second electronic device, and the second ACK message is used to indicate that the second electronic device has received 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 first delete the cache information corresponding to the target information, and then send the request to the first network device. The device sends a third indication message, so that the first network device can receive the third indication message.

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

It can be understood that if the second network device receives the second ACK message sent by the second electronic device, it can be considered that the second electronic device has successfully received the target information, that is, it can be considered that subsequent re-sending through the satellite network and the ground network may not be needed. Therefore, the second network device can delete the cache information corresponding to the target information, and send a third instruction message to the first network device to instruct the first network device to also delete the cache information corresponding to the target information.

Step 302: The first network device deletes cache information corresponding to the target information according to the third instruction 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.

It can be seen from this that since the first network device can delete the cache information corresponding to the target information according to the instructions of the second network device when the second electronic device receives the target information through the satellite network, this can avoid the need to send the target information to the second electronic device again. When the electronic device sends the target information, the first network device still stores the cache information corresponding to the target information. Therefore, the storage space of the first network device can be saved.

In another possible implementation of the present application, as shown in FIG. 5 in conjunction with FIG. 2 , after the above step 102 , the information transmission method provided by the embodiment of the present application may further include the following step 401 .

Step 401: Within the second preset time period from the time when the second network device sends the target information to the second electronic device through the satellite network, the first network device receives the first ACK message sent by the second electronic device. Next, the first network device sends a fourth instruction message to the second network device.

In the embodiment of the present application, the above-mentioned fourth instruction message is used to instruct the first network device to receive the first ACK message sent by the second electronic device, and the fourth instruction 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 preconfigured duration or a duration agreed upon in an agreement.

It can be understood that since the ground network of the first network device may be blocked, it may happen that the second electronic device has successfully received the target information, but it will take a long time for the first network device to receive the information sent by the second electronic device. In the case of the first ACK message, the first network device can receive the second electronic device within the second preset time period from the moment when the second network device sends the target information to the second electronic device through the satellite network. In the case of sending the first ACK message, the second network device is instructed to delete the cache information corresponding to the target information.

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 also 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 send the second information from the second cache area. The second information identifier corresponding to the target information is deleted from the queue.

It can be understood that since the second electronic device has successfully received the target information, the second network device no longer needs to send the target information to the second electronic device through the satellite network. Therefore, the second network device can obtain the target information from the above-mentioned second cache area. Delete cached information corresponding to the target information to save storage space of the second network device, and delete the second information identifier from the second information sending queue to prevent the second network device from sending the target information.

It can be seen that, when 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. Therefore, it can be avoided that there is no need to send the second electronic device to the second electronic device again. When the device sends target information, the second network device still stores cache information corresponding to the target information, thereby saving storage space of the second network device.

For the information transmission method provided by the embodiments of the present application, the execution subject may be an information transmission device, and the information transmission device may be a first information transmission device. In the embodiment of the present application, an information transmission device performing an information transmission method is used as an example to illustrate the information transmission device provided by the embodiment of the present application.

As shown in Figure 6, the first information transmission device 40 may include: a transmission module 41, configured to send the target to the second electronic device through the ground network when the first information transmission device receives the target information sent by the first electronic device. information; and if the first information transmission device does not receive the first ACK message sent by the second electronic device within the first preset time period, send a first request message to the second information transmission device, the first request The message carries target information, and the first request message is used to request the second information transmission device to send the target information to the second electronic device through the satellite network. Wherein, the above-mentioned first ACK message is used to indicate that the second electronic device has received the target information through the ground network.

An embodiment of the present application provides an information transmission device. The information transmission device is a first information transmission device. Since the first information transmission device can first send target information to the second electronic device through the ground network, and then send the target information to the second electronic device at the first preset time. When the first ACK message is not received within the segment, that is, when the second electronic device does not receive the target information, that is, when the second electronic device is located outside the coverage of the ground network of the first information transmission device. Next, the second information transmission device is requested to send the target information to the second electronic device through the satellite network, and the coverage of the satellite network of the second information transmission device is greater than the coverage of the ground network of the first information transmission device.
