[0032] Two-way satellite communication is gradually evolving from short message service to multimedia information transmission. The status of the two-way satellite communication link has a significant impact on the bandwidth, speed, and success rate of multimedia information transmission.

[0033] Currently, when the two-way satellite communication link is in poor condition, users experience slow transmission or frequent transmission failures when transmitting multimedia information. Therefore, a reliable communication method is lacking to achieve two-way satellite communication.

[0034] To address the aforementioned technical problems, this disclosure provides a communication method. Here, the transmission mode supported by the first electronic device in the first link indicates its communication capability in the first link, and the transmission mode supported by the second electronic device in the second link indicates its communication capability in the second link. Therefore, by performing data transmission based on a target transmission mode determined by the transmission modes supported by the first and second electronic devices in the first and second links, it can be ensured that the data transmission requirements do not exceed the communication capabilities of the first and second electronic devices. This ensures reliable data transmission between the first and second electronic devices.

[0049] The communication method provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0050] The communication method provided in this embodiment can be applied to the first electronic device 101 in the communication system shown in FIG1. ​​FIG2 shows a flowchart of a communication method, which includes the following steps S201-S203.

[0051] In S201, the transmission mode supported by the first electronic device in the first link is determined.

[0052] Here, the first link is the communication link between the first electronic device and the non-ground device.

[0053] In some embodiments, the first electronic device may determine the transmission mode supported by the first electronic device in the first link based on the capabilities of the first electronic device and the capabilities of non-terrestrial devices in the first link.

[0054] In some embodiments, the transmission mode supported by the first electronic device in the first link can indicate at least one of the following: the type of data transmitted, the transmission speed, and the transmission capacity.

[0055] S202. Determine the target transmission mode based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link.

[0056] Here, the second link is the communication link between the second electronic device and the non-ground device.

[0057] S203. Based on the target transmission mode, data is transmitted with the second electronic device.

[0058] It should be understood that since the transmission mode supported by the first electronic device in the first link indicates its communication capability in the first link, and the transmission mode supported by the second electronic device in the second link indicates its communication capability in the second link, data transmission can be performed using a target transmission mode determined based on the transmission modes supported by the first and second electronic devices in the first and second links. This ensures that the data transmission requirements do not exceed the communication capabilities of the first and second electronic devices. Thus, reliable data transmission between the first and second electronic devices can be guaranteed.

[0059] In some embodiments, the type of data transmitted includes at least one of the following: video, images, voice, and text.

[0060] In some embodiments, in S201 above, determining the transmission mode supported by the first electronic device in the first link is achieved by: obtaining link information of the first link; and determining the transmission mode supported by the first electronic device based on the link information of the first link.

[0061] It should be understood that the link information of the first link can reflect communication capability information such as communication distance, communication signal strength, and communication speed between the first electronic device and the non-ground device in the first link; therefore, the transmission mode supported by the first electronic device can be reliably determined based on the link information of the first link.

[0062] In some embodiments, the link information includes at least one of the following: non-ground equipment signal strength, non-ground equipment elevation angle, non-ground equipment tilt angle, non-ground equipment track height, non-ground equipment track type, received power of the first electronic device, transmitted power of the first electronic device, multipath interference information of the first link, real-time bit error rate of the first link, and number of non-ground equipment antennas of the first electronic device.

[0063] It should be understood that the signal strength of non-ground equipment refers to the strength of the signal transmitted by non-ground equipment to the first electronic device; the stronger the signal strength of non-ground equipment, the higher the communication quality corresponding to the first link.

[0064] It should be understood that the elevation angle of the non-ground device is the vertical angle of the non-ground device relative to the horizon. It can indicate the angle of the non-ground device relative to the first electronic device in the sky. The higher the elevation angle of the non-ground device, the fewer obstacles there may be between the non-ground device and the first electronic device (e.g., the thinner the atmosphere, or the less terrain that may block the path), and the shorter the signal path between the non-ground device and the first electronic device.

[0065] It should be understood that the tilt angle of non-ground equipment is the angle between the orbital plane of the non-ground equipment and the equatorial plane of the Earth, used to indicate the degree of inclination of the non-ground equipment's orbit relative to the equator. Different tilt angles result in different coverage areas for the non-ground equipment.

[0066] For example, based on the tilt angle of non-ground equipment, non-ground equipment tracks can be classified as: equatorial track, polar track, and inclined track.

[0067] It's important to note that since the latitude and longitude of an electronic device indicate the angle between the device and the Earth's equatorial plane, the difference between the latitude and longitude of the electronic device and that of a non-ground device indicates the vertical distance between the line connecting the electronic and non-ground devices and the Earth's plane where the electronic device is located. A smaller difference indicates a higher vertical distance, meaning the non-ground device is closer to being directly above the electronic device. It should be understood that the closer the non-ground device is to being directly above the electronic device, the fewer obstacles exist between them (e.g., fewer buildings, less terrain like mountains, less atmospheric thickness), resulting in higher communication quality.

[0068] In some embodiments, for electronic devices in regions with different latitudes and longitudes, non-ground devices with corresponding tilt angles can be used to provide services or to establish communication links.

[0069] For example, for the first electronic device in a polar region, the non-ground device in its first link can be a polar non-ground device.

[0070] It should be understood that the orbital altitude of non-ground equipment refers to the distance of the non-ground equipment from the Earth's surface. Different orbital altitudes result in different operating characteristics and application scenarios for non-ground equipment.

[0071] For example, low-Earth orbit (LEO) non-ground devices have short communication distances and low signal delays, but limited coverage. For geostationary orbit (GEO) non-ground devices, since they are stationary relative to the ground, they can more easily and stably provide communication services to electronic devices within the coverage area.

[0072] It should be understood that the receiving power of the first electronic device is the power of the first electronic device when receiving signals. The greater the receiving power, the better the quality of the signal received by the first electronic device and the higher the communication quality.

[0073] It should be understood that the transmission power of the first electronic device is the power of the signal transmitted by the first electronic device. The greater the transmission power, the stronger the signal received by the other end of the first electronic device, and the higher the communication quality.

[0074] It should be understood that the multipath interference information of the first link refers to the relevant information of the signal reaching the receiving end through multiple paths due to phenomena such as reflection, refraction, and scattering in the first link; the more severe the multipath interference, the lower the communication quality of the first link.

[0075] It should be understood that the real-time bit error rate of the first link is the proportion of errors that occur in the data passing through the first link. The higher the real-time bit error rate, the lower the communication quality and reliability of the first link.

[0076] It should be understood that the number of non-terrestrial antennas of the first electronic device reflects the signal transmission capability of the first electronic device. The more non-terrestrial antennas there are, the stronger the signal transmission capability of the first electronic device.

[0077] In some embodiments, the above-mentioned determination of the transmission mode supported by the first electronic device based on the link information of the first link is achieved by: determining the transmission mode supported by the first electronic device as a first candidate transmission mode based on the first condition met by the link information of the first link.

[0078] It should be understood that if the link information of the first link satisfies the first condition, it means that the capabilities of the first electronic device and the non-ground device in the first link can support the first candidate transmission mode. In this case, the transmission mode supported by the first electronic device is determined to be the first candidate transmission mode.

[0079] In some embodiments, the transmission mode may include a high-speed transmission mode, a medium-speed transmission mode, and a low-speed transmission mode.

[0080] In some embodiments, the high-speed transmission mode, medium-speed transmission mode, and low-speed transmission mode can be referred to as high-speed multimedia information transmission mode, medium-speed multimedia information transmission mode, and low-speed multimedia information transmission mode, respectively.

[0112] For example, the first bit error rate range can be [0, 10^-9].

[0113] In some embodiments, the first quantity can be 2 or 3.

[0114] In some embodiments, the above-mentioned determination of the transmission mode supported by the first electronic device based on the link information of the first link is achieved by: determining the transmission mode supported by the first electronic device as a second candidate transmission mode based on the second condition satisfied by the link information of the first link.

[0115] In some embodiments, the transmission speed corresponding to the first candidate transmission mode is higher than the transmission speed corresponding to the second candidate transmission mode.

[0116] In some embodiments, the second candidate transmission mode may be a medium-speed transmission mode.

[0117] In some embodiments, the second condition includes at least one of the following:

[0163] In some embodiments, the second quantity is less than or equal to the first quantity.

[0164] In some embodiments, the second quantity can be 1 or 2.

[0165] It should be noted that the first quantity and the second quantity can be the same if there are multiple judgment parameters in the first and second conditions.

[0166] For example, if the two judgment conditions include judgments on bit error rate and number of antennas, both the first quantity and the second quantity can be 2.

[0167] In some embodiments, the above-mentioned determination of the transmission mode supported by the first electronic device based on the link information of the first link is achieved by: determining the transmission mode supported by the first electronic device as a third candidate transmission mode based on the link information of the first link satisfying a third condition.

[0188] In some embodiments, the minimum value of the second altitude angle interval is greater than or equal to the maximum value of the third altitude angle interval.

[0189] For example, the third elevation angle threshold can be 15 degrees.

[0190] For example, the third elevation angle range can be [0, 15 degrees].

[0194] In some embodiments, the third tilt angle condition may be determined based on the region where the first electronic device is located.

[0195] In some embodiments, the third track height condition may be that the non-ground equipment track height is less than or equal to the third track height threshold, or that the non-ground equipment track height is within the third track height range.

[0196] In some embodiments, the third track type condition can be that the non-ground equipment track type is a third non-ground equipment track type.

[0204] In some embodiments, the second receive power threshold is greater than the third receive power threshold.

[0205] In some embodiments, the minimum value of the second received power range is greater than or equal to the maximum value of the third received power range.

[0206] In some embodiments, the third density condition may be that the multipath interference power spectral density of the first link is greater than the third density threshold, or that the multipath interference power spectral density of the first link is within the third density range.

[0207] In some embodiments, the second density threshold is less than or equal to the third density threshold.

[0216] In some embodiments, the third quantity is less than or equal to the second quantity.

[0217] In some embodiments, the third quantity can be 1.

[0218] It should be noted that the second and third quantities can be the same if there are multiple judgment parameters in the second and third conditions.

[0219] For example, if the two judgment conditions include judgments on bit error rate and number of antennas, the second quantity and the third quantity can both be 1.

[0220] In some embodiments, at least one of the following conditions is satisfied: non-ground equipment signal strength, non-ground equipment elevation angle, non-ground equipment tilt angle, non-ground equipment track height, and non-ground equipment track type, determined based on parameters of the non-ground equipment in the first link; and / or,

[0221] The parameters of the first electronic device are determined based on at least one of the following conditions: the received power of the first electronic device, the transmitted power of the first electronic device, the multipath interference information of the first link, the real-time bit error rate of the first link, and the number of non-terrestrial antennas of the first electronic device.

[0222] It should be understood that for non-ground devices with different parameters to achieve the same communication capability, the conditions that need to be met for non-ground device signal strength, elevation angle, tilt angle, track height, or track type may differ. Therefore, at least one of the following conditions can be determined based on the parameters of the non-ground devices in the first link: non-ground device signal strength, elevation angle, tilt angle, track height, and track type.

[0223] It should be understood that for electronic devices with different parameters to achieve the same communication capability, the conditions that need to be met for the first electronic device's received power, transmitted power, multipath interference information of the first link, real-time bit error rate of the first link, or the number of non-terrestrial antennas of the first electronic device may differ. Therefore, at least one of the following conditions can be determined based on the parameters of the first electronic device in the first link: received power, transmitted power, multipath interference information of the first link, real-time bit error rate of the first link, and number of non-terrestrial antennas of the first electronic device.

[0224] In some embodiments, the target transmission mode is determined based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link, by means of: obtaining the transmission modes supported by the second electronic device; displaying the transmission modes supported by the first electronic device and the transmission modes supported by the second electronic device on the user interface; and determining the target transmission mode in response to the user's mode selection operation.

[0225] It should be understood that displaying the transmission modes supported by the first electronic device and the second electronic device through the user interface allows the user to select a transmission mode and determine the target transmission mode. This improves the user experience and allows the user to quickly and easily determine their desired transmission mode.

[0226] In some embodiments, the target transmission mode is the same transmission mode used by the first electronic device and the second electronic device selected by the user.

[0227] In some embodiments, the target transmission mode includes a transmission mode used by a first electronic device selected by the user and a transmission mode used by a second electronic device selected by the user.

[0228] In some embodiments, after determining the target transmission mode, the target transmission mode is sent to the second electronic device so that the second electronic device can transmit data based on the target transmission mode.

[0229] In some embodiments, the above-described S203, based on the target transmission mode, transmits data with the second electronic device in the following manner: displaying the service types supported by the target transmission mode on the user interface of the first electronic device; determining the target service type in response to the user's service selection operation; and transmitting data based on the target service type and the target transmission mode.

[0230] It should be understood that displaying the supported service types of the target transmission mode through the user interface allows users to select their desired service type; that is, in response to the user's service selection, the target service type is determined; and data transmission is performed based on the target service type and the target transmission mode. This allows users to select their desired service type from the supported service types of the target transmission mode for data transmission, thus improving the user experience.

[0231] In some embodiments, the service type may include at least one of the following: video transmission, video call, voice call, SMS, voice transmission, and image transmission.

[0232] In some embodiments, the method further includes: acquiring real-time link information of a first link and real-time link information of a second link; updating the transmission mode supported by the first electronic device and the transmission mode supported by the second electronic device based on the real-time link information of the first link and the real-time link information of the second link; and updating the target transmission mode based on the updated transmission mode supported by the first electronic device and the transmission mode supported by the second electronic device.

[0233] It should be understood that the link information in the first and second links can change over time; therefore, real-time link information of the first and second links can be obtained.

[0234] For example, the link information changes as the first or second electronic device moves.

[0235] It should be understood that the transmission modes supported by electronic devices may change if link information changes. Therefore, the transmission modes supported by the first and second electronic devices can be updated based on the real-time link information of the first and second links. This ensures that the transmission modes supported by the electronic devices are the same as those supported by the current link.

[0236] It should be understood that when the transmission modes supported by electronic devices change, the transmission mode used for data transmission may become a mode not supported by the current transmission mode. In this case, the target transmission mode can be updated based on the updated transmission modes supported by the first and second electronic devices. This ensures that even with changes in link information, the target transmission mode remains a mode supported by the electronic devices, guaranteeing the reliability of data transmission.

[0237] In some embodiments, the target transmission mode is a transmission mode that meets preset conditions; the preset conditions include at least one of the following: the data transmission speed meets the desired transmission speed, the power corresponding to the transmission mode meets the desired power, and the transmission quality corresponding to the transmission mode meets the desired transmission quality.

[0238] It should be understood that a target transmission mode that meets the data transmission requirements can be determined based on preset conditions.

[0239] In some embodiments, preset conditions may be used to indicate the need for data transmission.

[0240] In some embodiments, the target transmission mode is the transmission mode with the strongest transmission capability among the transmission modes jointly supported by both parties. The strongest transmission capability is determined by at least one of the following: transmission speed, transmission quality, and parameter delay.

[0241] In some embodiments, the target transmission mode includes the highest transmission mode supported by the first electronic device and the highest transmission mode supported by the second electronic device.

[0242] In some embodiments, the non-ground devices in the first link and the second link are the same non-ground device.

[0243] In some embodiments, the non-ground device in the first link and the non-ground device in the second link are different non-ground devices. The first link is a communication link between the first electronic device and the first non-ground device; the second link is a communication link between the second electronic device and the second non-ground device.

[0244] It should be noted that if the non-ground equipment in the first link and the non-ground equipment in the second link are different non-ground equipment, a relay node may exist between the first non-ground equipment and the second non-ground equipment. This relay node can be at least one of the following: a ground node, an airborne node, or a satellite. There are no restrictions on the data and type of the relay node.

[0245] In some embodiments, the method further includes: obtaining the identifier of a non-ground device in a first link and the identifier of a non-ground device in a second link; and determining whether the non-ground devices in the first link and the second link are the same non-ground device based on whether the identifiers of the non-ground devices in the first link and the non-ground devices in the second link are consistent.

[0246] It should be understood that by identifying the non-ground devices in the first link and the non-ground devices in the second link, it can be determined whether the non-ground devices in the two links are the same ground device.

[0247] In some embodiments, the target transmission mode may be determined by a non-terrestrial device; and the non-terrestrial device sends the target transmission mode to either the first electronic device or the second electronic device. For example, the non-terrestrial device acquires information about a first link and information about a second link, determines the transmission modes supported by the first electronic device and the second electronic device, and determines the target transmission mode based on the transmission modes supported by the first and second electronic devices. Alternatively, the non-terrestrial device acquires the transmission modes supported by the first and second electronic devices, and determines the target transmission mode based on the transmission modes supported by the first and second electronic devices.

[0248] In some embodiments, if the non-ground device in the first link and the non-ground device in the second link are different non-ground devices, the target transmission mode can be determined by the first non-ground device or the second non-ground device.

[0249] In some embodiments, when the non-ground device in the first link and the second link is the same non-ground device, the non-ground device can obtain the device information of the first electronic device and the device information of the second electronic device; and determine the target transmission mode based on the device information of the first electronic device, the device information of the second electronic device and the device information of the non-ground device.

[0250] It should be understood that when the non-ground device in the first link and the second link is the same non-ground device, the electronic device needs to send less information to the non-ground device when the non-ground device determines the target transmission mode, and can determine the target transmission mode more quickly.

[0251] In some embodiments, the target transmission mode determined by the non-ground equipment may be a transmission mode jointly supported by the first electronic device and the second electronic device.

[0252] In some embodiments, the target transmission mode determined by the non-ground device described above can be used to indicate the first transmission mode used by the first electronic device and the second transmission mode used by the second electronic device.

[0253] For example, a non-ground device can determine a first transmission mode used by a first electronic device and a second transmission mode used by a second electronic device, and send the first and second transmission modes to the first and second electronic devices.

[0254] In some embodiments, the above-described S203, based on the target transmission mode, performs data transmission with the second electronic device in the following manner:

[0255] Convert the first type of data into the second type of data; based on the target transmission mode, send the second type of data to the second electronic device; the target transmission mode supports the second type of data; or...

[0256] Based on the target transmission mode, receive the second type of data from the second electronic device.

[0257] It should be understood that if the target transmission mode supports the second type of data, the first type of data can be converted into the second type of data for transmission. This ensures that data types not supported by the target transmission mode can be transmitted, guaranteeing the reliability of data transmission.

[0258] In some embodiments, when the second electronic device converts the second type of data into the first type of data, the second electronic device may send information to the first electronic device to notify or instruct that the second type of data was converted from the first type of data; after receiving the second type of data and the information from the second electronic device, the first electronic device may convert the second type of data into the first type of data.

[0259] It should be understood that converting the second type of data into the first type of data enables the first electronic device to receive the first type of data that the second electronic device expects to send, thereby improving the user experience.

[0260] In some embodiments, S202 above, determining the target transmission mode based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link, is achieved in the following manner: receiving a first negotiation request sent by the second electronic device, the first negotiation request including the transmission modes supported by the second electronic device; determining a negotiated transmission mode based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link; sending a first negotiation response to the second electronic device, the first negotiation response including the negotiated transmission mode; receiving a negotiation confirmation message sent by the second electronic device, the negotiation confirmation message indicating whether the second electronic device allows data transmission based on the negotiated transmission mode; determining the negotiated transmission mode as the target transmission mode based on the negotiation confirmation message indicating that the second electronic device does not allow data transmission based on the negotiated transmission mode; or, determining a new negotiated transmission mode based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link based on the negotiation confirmation message indicating that the second electronic device does not allow data transmission based on the negotiated transmission mode; and sending a second negotiation response to the second electronic device, the second negotiation response including the new negotiated transmission mode.

[0261] It should be understood that the first negotiation request and the negotiation confirmation message enable the first electronic device and the second electronic device to complete the negotiation of the target transmission mode, ensuring that the negotiated transmission mode desired by the first electronic device is the transmission mode allowed by the second electronic device, and ensuring that the target transmission mode is a transmission mode jointly supported or allowed by both parties, thereby ensuring the reliability of data transmission.

[0262] It should be understood that when a negotiation confirmation message is used to instruct the second electronic device not to transmit data based on the negotiated transmission mode, the first electronic device can determine a new negotiation transmission mode so that the second electronic device can determine whether to allow data transmission through the new negotiation transmission mode, thus ensuring the reliability of data transmission.

[0263] In some embodiments, the process of determining the target transmission mode through a first negotiation request and a negotiation confirmation message can be referred to as the first electronic device and the second electronic device handshaking together to negotiate the target transmission mode.

[0264] For example, as shown in FIG3, a flowchart of another communication method provided in this disclosure is used to indicate the process of handshaking and negotiating a target transmission mode between a first electronic device and a second electronic device, including: the first electronic device and the second electronic device establishing an initialization channel; the first electronic device acquiring multimedia information transmission modes supported by the first electronic device; the first electronic device determining a desired multimedia transmission mode and sending it to the second electronic device; the second electronic device acquiring multimedia information transmission modes supported by the second electronic device; the second electronic device comparing the desired multimedia transmission mode with the highest multimedia information transmission mode supported by the second electronic device, and determining a multimedia information transmission mode jointly supported by the first and second electronic devices; the second electronic device sending a multimedia information transmission mode negotiation request to the first electronic device; the first electronic device receiving the multimedia information transmission mode negotiation request and confirming whether it supports the transmission mode in the multimedia information transmission mode negotiation request; the first electronic device generating a multimedia information transmission mode negotiation request confirmation message; the first electronic device sending the multimedia information transmission mode negotiation request confirmation message to the second electronic device; the second electronic device receiving the multimedia information transmission mode negotiation request confirmation message; and the second electronic device using the multimedia information transmission mode negotiation request confirmation message to instruct the first electronic device to support the transmission mode in the multimedia information transmission mode negotiation request, and starting data transmission.

[0265] In some embodiments, the target transmission mode obtained by the handshake negotiation can be a transmission mode used by both the first electronic device and the second electronic device, that is, both parties use the same transmission mode.

[0266] In some embodiments, the above-described S202, based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link, determines the target transmission mode by means of the following: displaying the transmission modes supported by the first electronic device on the user interface of the first electronic device; sending the user-selected transmission mode to the second electronic device in response to the user's mode selection operation; receiving a first response from the second electronic device; the first response including the target transmission mode determined by the second electronic device based on the user-selected transmission mode; and determining the target transmission mode based on the first response.

[0267] It should be understood that by displaying the transmission modes supported by the first electronic device, the user can select the desired transmission mode.

[0268] It should be understood that by sending the user-selected transmission mode and the first response to the second electronic device, the first electronic device can obtain the target transmission mode determined by the second electronic device based on the user-selected transmission mode. In this way, it can be ensured that the target transmission mode is a transmission mode that is supported or allowed by both the first and second electronic devices, thereby ensuring the reliability of data transmission.

[0269] In some embodiments, the transmission mode selected by the user is a transmission mode used by both the first electronic device and the second electronic device, that is, both use the same transmission mode.

[0270] In some embodiments, the transmission mode selected by the user is a first transmission mode used by the first electronic device and a second transmission mode used by the second electronic device. In this case, the transmission mode sent to the second electronic device includes the second transmission mode, and the second electronic device determines a first response based on whether it supports or allows the use of the second transmission mode. The first electronic device determines the target transmission mode, including both the first and second transmission modes, based on the first response indicating that it supports or allows the use of the second transmission mode; or the first electronic device determines and notifies the second electronic device of a new second transmission mode based on the first response indicating that it does not support or allows the use of the second transmission mode, in order to obtain a new first response; and determines the target transmission mode based on the new first response.

[0271] In some embodiments, the transmission mode sent to the second electronic device includes a first transmission mode and a second transmission mode. This allows the second electronic device to be notified of the first electronic device's use of the first transmission mode.

[0272] In some embodiments, S202 above determines a target transmission mode based on the transmission modes supported by the first electronic device in the first link and the transmission modes supported by the second electronic device in the second link, which is achieved by: determining a first transmission mode used by the first electronic device for data transmission; receiving a second transmission mode from the second electronic device; the second transmission mode being the transmission mode used by the second electronic device for data transmission; and determining the first transmission mode and the second transmission mode as the target transmission mode.

[0273] It should be understood that by determining the first transmission mode used by the first electronic device for data transmission, the transmission mode used for data transmission in the first link can be determined.

[0274] It should be understood that by receiving the second transmission mode from the second electronic device, the transmission mode used for data transmission in the second link can be determined. Furthermore, the transmission mode used for data transmission on the first and second links can be determined as the target transmission mode. This ensures that the first electronic device can determine the data transmission capabilities on the first and second links when data is transmitted between the first and second electronic devices, guaranteeing that the first electronic device can transmit data with the second electronic device in a link-supported manner, thus ensuring the reliability of data transmission.

[0275] In some embodiments, the method further includes sending a first transmission mode to a second electronic device.

[0276] It should be understood that by sending the first transmission mode to the second electronic device, the ability of the second electronic device to transmit data via the first link can be guaranteed, the second electronic device can transmit data in a way supported by the link, and the reliability of data transmission can be guaranteed.

[0277] In some embodiments, the target transmission mode is used to indicate that: a first electronic device transmits data through a first transmission mode, and a second electronic device transmits data through a second transmission mode.

[0278] In some embodiments, the transmission capability of the first transmission mode is higher than that of the second transmission mode; the first transmission mode supports at least the transmission of first type and second type data; the second transmission mode supports at least the transmission of second type data; data transmission with the second electronic device based on the target transmission mode includes: converting the first type data into second type data when the first type data exceeds the transmission capability of the second transmission mode; sending the second type data to the second electronic device based on the first transmission mode; or receiving data from the second electronic device based on the first transmission mode.

[0279] It should be understood that when the transmission capacity of the first transmission mode is higher than that of the second transmission mode, it means that the first transmission mode can transmit more data types than the second transmission mode. That is, the first transmission mode supports the transmission of both first and second type data; the second transmission mode supports the transmission of second type data.

[0280] It should be noted that the first transmission mode and / or the second transmission mode can support multiple data types.

[0281] For example, the transmission capacity required for video transmission mode is greater than that required for image transmission mode, the transmission capacity required for image transmission mode is greater than that required for voice transmission mode, and the transmission capacity required for voice transmission mode is greater than that required for text transmission mode.

[0282] For example, the data types supported by the first transmission mode may include video, images, voice, and text, and the data types supported by the second transmission mode may include at least one of the following: images, voice, and text.

[0283] For example, the data types supported by the first transmission mode may include images, voice, and text, and the data types supported by the second transmission mode may include at least one of the following: voice and text.

[0284] For example, the data types supported by the first transmission mode may include voice and text, and the data types supported by the second transmission mode may include one of the following: text and voice.

[0285] In some embodiments, the data type of text may be referred to as SMS, short message, or brief news.

[0286] It should be understood that if the transmission capacity of the first type of data exceeds that of the second transmission mode, it indicates that the second transmission mode does not support the transmission of the first type of data. In this case, the first type of data can be converted into the second type of data so that the data can be transmitted on the second link, thus ensuring the reliability of data transmission.

[0287] It should be understood that since the transmission capability of the first transmission mode is higher than that of the second transmission mode, the first electronic device can receive data from the second electronic device based on the first transmission mode, regardless of the type of data sent by the second electronic device.

[0288] In some embodiments, the transmission capability of the first transmission mode is higher than that of the second transmission mode; the first transmission mode supports at least the transmission of first type and second type of data; the second transmission mode supports at least the transmission of second type of data; data transmission with the second electronic device based on the target transmission mode includes: sending first type of data to a relay node so that the relay node sends second type of data to the second electronic device; the relay node is used to convert the first type of data into second type of data when the first type of data exceeds the transmission capability of the second transmission mode; the relay node is one of the following: a non-ground device in the first link, a non-ground device in the second link, or a relay node between a non-ground device in the first link and a non-ground device in the second link.

[0289] It should be understood that data type conversion does not need to be performed on the first electronic device; the relay node can complete the conversion of data of the first type to data of the second type. In this way, the processing resources of the first electronic device can be saved.

[0290] In some embodiments, if the processing capability of the first electronic device is lower than the capability threshold or the number of processing resources is less than the quantity threshold, the relay node converts the first type of data into the second type of data if the first type of data exceeds the transmission capability of the second transmission mode.

[0291] In some embodiments, the transmission capability of the first transmission mode is lower than that of the second transmission mode; the first transmission mode supports at least the transmission of second type data, and the second transmission mode supports at least the transmission of first type data and second type data; data transmission with the second electronic device based on the target transmission mode includes: sending second type data to the second electronic device based on the first transmission mode; or receiving second type data based on the first transmission mode; here, the second type data is sent by the second electronic device, or the second type data is obtained by converting first type data to be sent to the second electronic device.

[0292] It should be understood that since the transmission capacity of the first transmission mode is lower than that of the second transmission mode, the second type of data transmitted by the first electronic device can be transmitted on the second link. At this time, the first electronic device sends the second type of data to the second electronic device based on the first transmission mode.

[0293] It should be understood that the second type of data received by the first electronic device based on the first transmission mode can be sent by the second electronic device or obtained by converting the first type of data to be sent by the second electronic device.

[0294] It should be noted that the second type of data obtained by converting the first type of data to be transmitted by the second electronic device can be converted by the second electronic device itself, or it can be converted by non-ground devices or other relay nodes.

[0295] It should be noted that when the transmission capacity of the first transmission mode is lower than that of the second transmission mode, the first transmission mode and / or the second transmission mode can support multiple data types.

[0296] For example, when the transmission capability of the first transmission mode is lower than that of the second transmission mode, the data types supported by the second transmission mode may include video, images, voice, and text, and the data types supported by the first transmission mode may include at least one of the following: images, voice, and text.

[0297] For example, when the transmission capability of the first transmission mode is lower than that of the second transmission mode, the data types supported by the second transmission mode may include images, voice, and text, and the data types supported by the first transmission mode may include at least one of the following: voice and text.

[0298] For example, when the transmission capability of the first transmission mode is lower than that of the second transmission mode, the data types supported by the second transmission mode may include voice and text, and the data types supported by the first transmission mode may include one of the following: text and voice.

[0299] In some embodiments, when the transmission capacity of the first transmission mode is lower than that of the second transmission mode, the above-mentioned sending of the second type of data to the second electronic device based on the first transmission mode is achieved by: acquiring the data to be sent from the first electronic device; converting the data to be sent into the second type of data when the data to be sent exceeds the capacity of the first transmission mode; and sending the second type of data to the second electronic device based on the first transmission mode.

[0300] It should be understood that when the transmission capacity of the first transmission mode is lower than that of the second transmission mode, and the data to be transmitted by the first electronic device exceeds the capacity of the first transmission mode, the first electronic device can convert the data to be transmitted into a second type of data; based on the first transmission mode, it can then send the second type of data to the second electronic device. In this way, the content corresponding to the data exceeding the transmission capacity can be transmitted via the second type, ensuring the reliability of data transmission.

[0301] The communication method provided in this embodiment can be applied to the first non-ground device 102, the second non-ground device 104, or the relay node 105 in the communication system shown in FIG1. ​​Since the first non-ground device 102 or the second non-ground device 104 also plays the role of relay or data relay in the first electronic device and the second electronic device, the first non-ground device 102, the second non-ground device 104, and the relay node 105 are collectively referred to as relay nodes. The relay node is used to provide relay services to the first electronic device and the second electronic device; the first electronic device transmits data through a first transmission mode, and the second electronic device transmits data through a second transmission mode; the first transmission mode supports the transmission of first type and second type of data, and the second transmission mode supports second type of data; the transmission capacity of the first transmission mode is higher than that of the second transmission mode. FIG4 shows a flowchart of another communication method. As shown in FIG4, this communication method includes the following S401-S405.

[0302] In S401, data of the first type is received from the first electronic device; in S402, if the data of the first type exceeds the capability of the second transmission mode, the data of the first type is converted into data of the second type; in S403, the data of the second type is sent to the second electronic device.

[0303] It should be understood that if the first type of data exceeds the capabilities of the second transmission mode, it indicates that the link between the second electronic device and the non-terrestrial device does not support the transmission of the first type of data. In this case, the first type of data is converted into second type of data and sent to the second electronic device. Thus, through data conversion, data can reach the second electronic device via the link between the second electronic device and the non-terrestrial device, ensuring the reliability of data transmission.

[0304] Alternatively, in S404, second type of data is received from the second electronic device. In S405, second type of data is sent to the first electronic device.

[0305] It should be understood that since the transmission capacity of the first transmission mode is higher than that of the second transmission mode, data that can be transmitted through the link between the second electronic device and the non-ground device can also be transmitted through the link between the first electronic device and the non-ground device. Therefore, the relay node receives the second type of data from the second electronic device and sends the second type of data to the first electronic device.

[0306] In some embodiments, a relay node is one of the following: a non-ground device in a first link, a non-ground device in a second link, or a relay node between a non-ground device in the first link and a non-ground device in the second link; the first link is a communication link between a first electronic device and a non-ground device; and the second link is a communication link between a second electronic device and a non-ground device.

[0307] The disclosed embodiments can divide the communication device into functional modules according to the above method embodiments. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one functional module. The integrated module can be implemented in hardware or software. It should be noted that the module division in this disclosed embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods. The following description uses the example of dividing each functional module according to each function.
