It can be visual interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets displayed on the screen of an electronic device.

[0066] In recent years, with the rapid development of satellite communication technology, satellite communication services have become increasingly popular. Currently, it supports communication between electronic devices via satellite, enabling functions such as making phone calls in areas without mobile network coverage.

[0067] FIG. 1A A schematic diagram of the software structure of an electronic device 100 is shown.

[0068] Electronic device 100 can FIG. 1A The software structure shown establishes a communication connection with the satellite and enables communication or message transmission with other electronic devices via the satellite.

[0069] like FIG. 1A As shown, the software architecture of electronic device 100 may include an application layer, a framework layer, and a hardware abstraction layer (HAL).

[0070] The application layer may include one or more applications, such as the calling application 13, the contacts application, and the SMS application 19. The application layer also includes modules such as a settings module and a system UI module. The calling application 13 may also be called a telephone application, a dialer application, etc., and the SMS application 19 may also be called a messaging application, etc. This application does not limit the specific names of the applications.

[0071] The framework layer may include a satellite communication mode module 11, a satellite search service module 12, a telecom management module 14, a telephony service module 15, and a communication system framework (FWK-CS) 16.

[0072] The telecom module 14 can be used to transmit data between the telephony module 15 and the application layer.

[0073] The telephony service module 15 may include one or more call modules and connection modules corresponding to different communication modes. For example, a satellite call module and a satellite connection module for satellite communication mode; a call module and a telephony connection module for cellular communication mode; and a VoIP call module and a VoIP connection module for network communication mode. The telephony service module 15 can determine the current communication mode and bind the corresponding call service based on the current communication mode, that is, call the call module and connection module corresponding to the current communication mode.

[0074] The satellite communication mode module 11 can set the satellite communication mode, and after detecting that the satellite communication mode is enabled, it can also send a command to the satellite search service module 12. This command instructs the satellite search service module 12 to acquire satellite data, which may include the satellite's azimuth angle, elevation angle, and satellite signal strength relative to the device. The satellite communication mode module 11 can also provide satellite search guidance based on the satellite data displayed by the satellite search service module 12, guiding the user to establish a communication connection between the electronic device 100 and the satellite.

[0075] After receiving instructions from the satellite communication mode module 11, the satellite search service module 12 can acquire real-time satellite data and send the satellite data to the satellite communication mode module 11. In some embodiments, the satellite search service module 12 can determine the satellite data based on data collected by the global positioning service (GPS) module and the sensor module.

[0076] The communication system framework 16 may include a call framework, a text messaging framework, and a radio interface layer (RIL) - Java (also written as RILJ), which can also be called an interface layer that supports the Java language.

[0077] The call framework can include one or more telephone modules and voice call model modules corresponding to different communication modes. For example, a satellite phone module and a satellite phone call tracker for satellite communication mode; and a telephone module (GsmCdma phone) and a voice call model (GsmCdma phone call tracker) for cellular communication mode.

[0078] The SMS framework may include an SMS management module (Smsmanager) 16a, and one or more SMS schedulers corresponding to different communication modes, such as a satellite SMS scheduler (satellite Smsdispatcher) for satellite communication mode and an SMS scheduler (GsmSmsdispatcher) for cellular communication mode.

[0079] RILJ can transmit data between the communication system framework and the wireless communication interface layer. The communication connection between RILJ and the wireless communication interface layer can be a socket.

[0080] The HAL may include a radio interface layer (RIL) 17. RIL 17 can receive commands transmitted from the communication system framework and send the commands to the corresponding modem. RIL 17 may include one or more RIL sub-modules corresponding to different communication modes, such as a satellite interface layer (Satellite-RIL) for satellite communication mode and a vendor-RIL module for cellular communication mode. The satellite interface layer (Satellite-RIL) and the vendor-RIL module are independent of each other. The satellite-RIL module can send AT commands to the satellite communication modem 18 in the hardware layer. The vendor-RIL module can send AT commands to the cellular modem in the hardware layer. In addition, RIL 17 may also include modules such as the Radio Interface Layer (RILC), Lib-RIL, and Common-RIL that support the C programming language.

[0081] The software architecture of electronic device 100 can interact with one or more hardware components within it. This hardware may include a satellite communication modem 18, a cellular modem, a Bluetooth (BT) module, a high-fidelity (HiFi) module, a sensor module, and a global positioning service (GPS) module, wherein the satellite communication modem 18 and the cellular modem are independent of each other. The HiFi module may include a microphone, a speaker, a codec, and a power amplifier (PA).

[0082] When electronic device 100 makes or receives a call via satellite communication modem 18, satellite communication modem 18 can invoke the HiFi module to enable voice call functionality. In some embodiments, if electronic device 100 is also connected to other electronic devices such as Bluetooth headsets via Bluetooth module during a call, satellite communication modem 18 can also invoke the Bluetooth module.

[0083] After enabling satellite communication mode, the electronic device 100 can determine its location through the GPS module and begin satellite search guidance. The specific satellite search guidance method can be referred to the description in the following embodiments.

[0084] It should be noted that other Chinese names may be used for the above modules, and this application does not limit the Chinese names of the modules.

[0085] based on FIG. 1A As described, the HAL layer includes Satellite-RIL and Vendor-RIL, which are configured independently. The hardware layer includes a satellite modem and a cellular modem, which are also configured independently. Specifically, the Satellite-RIL interfaces with the satellite modem, and the Vendor-RIL interfaces with the cellular modem.

[0086] When electronic device 100 is connected to satellite 200 FIG. 1B A schematic diagram showing an electronic device 100 and a satellite 200 communicating with each other is shown.

[0087] like FIG. 1B As shown, the Satellite-RIL in the HAL layer interfaces with the satellite modem in the hardware layer. The satellite modem in the hardware layer is connected to satellite 200. When electronic device 100 needs to communicate with satellite 200, the application layer of electronic device 100 can send satellite communication data to Satellite-RIL, which then sends the satellite communication data to the satellite modem. Finally, the satellite modem sends the satellite communication data to satellite 200, and satellite 200 then sends the satellite communication data to other electronic devices. Similarly, satellite 200 can receive satellite communication data sent by other electronic devices, which then sends the satellite communication data to the satellite modem. The satellite modem then sends the satellite communication data to Satellite-RIL, and finally, Satellite-RIL sends the satellite communication data to the application layer of electronic device 100.

[0088] When electronic device 100 is connected to base station 300 FIG. 1C A schematic diagram showing another type of electronic device 100 communicating with a base station 300 is shown.

[0089] like FIG. 1CAs shown, the Vendor-RIL in the HAL layer interfaces with the cellular modem in the hardware layer. The cellular modem in the hardware layer is connected to the base station 300. When electronic device 100 needs to communicate with base station 300, the application layer of electronic device 100 can send cellular communication data to the Vendor-RIL, which then sends the cellular communication data to the cellular modem. Finally, the cellular modem sends the cellular communication data to base station 300, which then sends the cellular communication data to other electronic devices. Similarly, base station 300 can receive cellular communication data sent by other electronic devices, which then sends the cellular communication data to the cellular modem. The cellular modem then sends the cellular communication data to the Vendor-RIL, which finally sends the cellular communication data to the application layer of electronic device 100.

[0090] When electronic device 100 is connected to satellite 200, from FIG. 1B and FIG. 1C It is known that the Vendor-RIL and Satellite-RIL in the HAL layer are configured independently, and the satellite modem and cellular modem in the hardware layer are configured independently. The cellular modem in the hardware layer has no knowledge of the satellite modem's status, nor can it know whether the satellite modem is connected to satellite 200. The cellular modem also cannot know when to detect a cellular signal or when to prompt the user to switch cellular networks. Currently, electronic device 100 can only trigger the cellular modem to detect a cellular signal and prompt the user to switch cellular networks when it detects that the user has manually turned off the satellite call connection, making user operation complex.

[0091] The satellite communication system 10 involved in the satellite communication method provided in the embodiments of this application will be described below.

[0092] like FIG. 1D As shown, the satellite communication system 10 may include electronic equipment 100, satellite 200 and base station 300.

[0093] In the satellite communication system 10, electronic device 100 can establish a satellite communication connection with satellite 200. Thus, when electronic device 100 is in an area without cellular network coverage, it can send messages to other electronic devices via satellite 200, enabling communication between electronic device 100 and other devices.

[0094] In some embodiments, the electronic device 100 may periodically / irregularly acquire the signal type of the cellular signal received by the antenna on the electronic device 100 to confirm whether the electronic device 100 is within the coverage area of ​​the cellular network.

[0095] Electronic device 100 can also obtain the cellular signal type corresponding to the SIM card installed on it. If the cellular signal type received by the antenna on electronic device 100 is the same as the cellular signal type corresponding to the SIM card installed on it, electronic device 100 can prompt the user whether to switch to a cellular network. When the user confirms switching to a cellular network, electronic device 100 can disconnect its satellite communication connection with satellite 200 and establish a connection with base station 300, enabling it to establish a cellular network connection with base station 300 and send messages to other electronic devices through base station 300. If the user confirms not to switch to a cellular network, electronic device 100 can maintain its satellite communication connection with satellite 200.

[0096] Optionally, the electronic device 100 can also detect the signal strength of the cellular signal received by its antenna. If the signal type of the cellular signal received by the antenna on the electronic device 100 is the same as the cellular signal type corresponding to the SIM card installed on the electronic device 100, and the signal strength of the cellular signal received by the antenna on the electronic device 100 is greater than a first threshold, then the electronic device 100 will prompt the user whether to switch to the cellular network. This ensures that the electronic device 100 only switches to the cellular network when the cellular signal is strong.

[0097] Optionally, to avoid data transmission failure caused by the electronic device 100 switching to the cellular network when transmitting data between the electronic device 100 and the satellite 200, the electronic device 100 may prompt the user whether to switch to the cellular network when it is in an idle state.

[0098] Optionally, the electronic device 100 may also detect the signal type and signal strength of the cellular signal received by the antenna on the electronic device 100 when it is in a busy state, and the electronic device 100 may also detect the signal type and signal strength of the cellular signal received by the antenna on the electronic device 100 when it is in an idle state. This application does not limit this.

[0099] The term "electronic device 100 is in an idle state" can mean that there is no data to be transmitted between electronic device 100 and satellite 200. For example, electronic device 100 has no data to send to satellite 200, nor does it need to receive data from satellite 200.

[0100] The term "busy" for electronic device 100 can mean that there is data to be transmitted between electronic device 100 and satellite 200. For example, electronic device 100 may be sending data to satellite 200 or is currently sending data to satellite 200, or electronic device 100 may need to receive data from satellite 200 or is currently receiving data from satellite 200.

[0202] like FIG. 2EAs shown, the satellite search page 240 may include a shutdown control 241, an intensity indicator 242, and satellite search operation prompts (including text prompts 243 and animated prompts 244). The shutdown control 241 can be used to trigger the electronic device 100 to shut down its satellite communication mode. The intensity indicator 242 is used to indicate the strength of the satellite signal. The satellite search operation prompts are used to instruct the user to perform satellite search operations. For example, the text prompt 243 may include the text "Try to be in an open outdoor area, avoiding obstructions to the signal." The animated prompt 244 can be used to indicate whether the electronic device 100 has detected a satellite. The animated prompt 244 may include a fan-shaped area that can be used to indicate the positional relationship between the satellite's location and the antenna pointing of the electronic device 100. FIG. 2E In the embodiment shown, the animation prompt 244 does not contain a symbol representing a satellite, which is used to indicate to the user that the current electronic device 100 has not yet searched for a satellite.

[0203] After the electronic device 100 locates a satellite, it can close the satellite search page 240 and display the satellite's position relative to the electronic device 100 as shown below. FIG. 2F The alignment page 250 is shown. The position of the satellite relative to the electronic equipment 100 can be represented by elevation and azimuth angles.

[0204] like FIG. 2F As shown, the alignment page 250 may include a close control 251, an intensity indicator 252, a card display control 255, and alignment operation prompts (including text prompts 253 and animated prompts 254).

Animated prompt 254 may include a fan-shaped area, which can be used to indicate the azimuth angle between the satellite's location and the antenna of the electronic device 100. FIG. 2FIn the animation prompt 254 shown, the symbol representing the satellite (hereinafter referred to as the satellite) is located on the right side of the fan-shaped area. Therefore, the user needs to rotate the electronic device 100 to the right to position the satellite within the fan-shaped area, ensuring that the electronic device 100 establishes a good communication connection with the satellite via its antenna. Furthermore, the animation prompt 254 may also include a small ball, the position of which can be used to indicate the pitch angle of the electronic device 100 relative to the satellite. The animation prompt 254 may also include an arrow indicating that the user is rotating the device to the right. Additionally, a satellite symbol 201a may be displayed on the desktop to indicate that the electronic device 100 has currently detected a satellite. In other embodiments, the satellite symbol 201a may also be displayed after the electronic device 100 establishes a communication connection with the satellite, or after enabling satellite communication mode.

[0205] Understandable, FIG. 2F The alignment page 250 shown is just an example. In some embodiments, if the satellite is in a different position relative to the antenna of the electronic device 100, the alignment operation prompts in the alignment page 250 may also be changed accordingly (for example, when the satellite is on the left side of the fan-shaped area, prompt the user to turn the device to the left, etc.). This application does not limit this.

[0206] After rotating the electronic device 100 to the right so that the satellite is positioned in the sector area, as follows FIG. 2G As shown, the electronic device 100 can change the alignment operation prompts.

[0207] like FIG. 2G As shown, on alignment page 250, text prompt 253 could be "Tilt the device upwards to move the ball to the center area." In animation prompt 254, the satellite can be located in a fan-shaped area, and a directional arrow can be displayed near the ball, instructing the user to tilt the device to move the ball upwards. When the ball moves to the center area, the pitch angle of the electronic device 100 relative to the satellite is adjusted.

[0208] Understandable, FIG. 2G The alignment page 250 shown is just an example. In some embodiments, the pitch angle of the electronic device 100 relative to the satellite may also be different from the above embodiment. In this case, the position of the ball in the animation prompt may also be different from the above. FIG. 2G The embodiments shown are different, and this application does not limit them.

[0209] After alignment is complete, the electronic device 100 can close the alignment page 250 and display the following on the desktop: FIG. 2H The satellite connection page 260 is shown.

[0210] like FIG. 2HAs shown, the satellite connection page 260 may include a close control 261, a card display control 262, an intensity indicator 263, and operation prompts (including text prompts 264 and animated prompts 265). Optionally, the satellite connection page 260 may also display the current latitude and longitude information of the electronic device 100, such as "36°44'00" North latitude and "98°5'00" East longitude," and may also display the update time of the latitude and longitude, such as "refreshed just now." The functional descriptions of the close control 261 and the intensity indicator 263 can be found in the functional descriptions of the relevant controls in the above embodiments, and will not be repeated here. The card display control 262 can be used to trigger the electronic device 100 to close the display of the satellite connection page 260 and display a satellite status card, which includes some or all of the content in the satellite connection page 260. The operation prompts can be used to instruct the user on the operations during the satellite connection process. For example, the text prompt 264 may be the text "Maintain the current gesture and avoid large deviations." The animated prompt 265 can indicate to the user whether the posture of holding the device is correct. For example, if the satellite is located within a fan-shaped area and the ball is located within the center area, the user's handhold posture is correct. In other cases, the user needs to adjust the handhold posture. The animation prompt 265 can also display multiple concentric circles to indicate that the electronic device 100 is establishing a communication connection with the satellite. Furthermore, the satellite connection page 260 can display the title "Connecting," to inform the user that the electronic device 100 is currently establishing a communication connection with the satellite. Optionally, a countdown timer, such as "15 seconds," can be displayed next to the title.

[0211] After electronic device 100 successfully establishes a connection with the satellite, such as FIG. 2I As shown, the electronic device 100 can change the signal strength in the strength indicator 263 and display a connection success message 266.

[0212] like FIG. 2I As shown, the signal strength in strength indicator 263 is three bars, while FIG. 2H The signal strength in the strength indicator 263 shown is zero. The connection success message 266 can be... FIG. 2H The displayed title "Connecting" is changed to "Satellite connection successful". Furthermore, the electronic device 100 can also display a phone application icon 267 and a text messaging application icon 268 on the satellite connection page 260, both of which display a satellite symbol to indicate to the user that satellite communication mode is currently in use. Additionally, after successfully establishing a connection with the satellite, the electronic device 100 can turn off the multiple concentric circles in the animated prompt 265 to indicate to the user that the communication connection has been established.

[0213] Optional, FIG. 2A-FIG. 2IThe illustration shows an electronic device 100 establishing a satellite communication connection with satellite equipment when it cannot receive a cellular network signal. In other embodiments, the electronic device 100 may also establish a satellite communication connection with satellite equipment when it receives a cellular network signal; this application does not limit this to any particular embodiment.

[0214] Electronic device 100 maintains a satellite communication connection with satellite 200 and prompts the user whether to switch to cellular network.

[0215] In some embodiments, after establishing a satellite communication connection with the satellite 200, the electronic device 100 can automatically detect cellular signals near the electronic device 100 and prompt the user to switch to the cellular network after detecting the cellular signal, without requiring the user to manually close the satellite communication connection before switching to the cellular network.

[0216] FIG. 3A-FIG. 3H The diagram shows a user interface (UI) that prompts the user to switch to a cellular network after the electronic device 100 establishes a satellite communication connection with the satellite 200.

[0217] For example, such as FIG. 3A As shown, after electronic device 100 establishes a satellite communication connection with satellite 200, if electronic device 100 exits the satellite connection page 260, electronic device 100 can display... FIG. 3A The desktop shown. FIG. 3A The desktop shown includes multiple application icons, as well as a satellite liveness capsule 3101. The satellite liveness capsule 3101 may include a strength indicator to inform the user of the current satellite signal strength, for example, by... FIG. 3A As shown in Satellite Real-Time Capsule 3101, the current satellite signal strength is three bars.

[0218] Optionally, after electronic device 100 establishes a satellite communication connection with satellite 200, if electronic device 100 exits the satellite connection page 260, electronic device 100 can also display... FIG. 3B The desktop shown. FIG. 3B The desktop shown includes multiple application icons and a satellite status card 3102. The satellite status card 3102 is used to notify the user that the electronic device 100 has successfully established a communication connection with the satellite. The satellite status card 3102 may include a signal strength indicator, operation prompts, latitude and longitude information, etc. The signal strength indicator is used to indicate the current satellite signal strength to the user, for example, by... FIG. 3B As shown in the satellite status card 3102, the current satellite signal strength is three bars. The operation prompts are used to guide the user to maintain or adjust the current posture of holding the electronic device while pointing it at the satellite 200.

[0219] In some embodiments, the electronic device 100 may receive user requests for... FIG. 3A The satellite live capsule 3101 shown here allows for input operations, such as a click operation. In response to the user's input, the electronic device 100 can display... FIG. 3B The satellite live feed card shown is 3102.

[0220] The following embodiments of this application illustrate the use of the display of a satellite status card 3102 after the electronic device 100 exits the satellite connection page 260.

[0221] In some embodiments, the electronic device 100 may periodically / irregularly detect the type of cellular signal near the electronic device 100 to detect whether the electronic device 100 is within the coverage area of ​​the cellular network.

[0222] Electronic device 100 can also obtain the cellular signal type corresponding to the SIM card installed on electronic device 100.

[0223] Electronic device 100 can receive cellular signals via an antenna. If the signal type of the cellular signal received by electronic device 100 via its antenna is the same as the cellular signal type corresponding to the SIM card installed on electronic device 100, electronic device 100 can prompt the user whether to switch to the cellular network. When the user confirms switching to the cellular network, electronic device 100 can disconnect its satellite communication connection with satellite 200 and establish a connection with base station 300, enabling electronic device 100 to use the cellular network provided by base station 300 and send messages to other electronic devices through base station 300. When the user confirms not to switch to the cellular network, electronic device 100 can maintain its satellite communication connection with satellite 200.

[0224] Optionally, the electronic device 100 can also detect the signal strength of the cellular signal received by the electronic device 100 through its antenna. If the signal type of the cellular signal received by the electronic device 100 through its antenna is the same as the cellular signal type corresponding to the SIM card installed on the electronic device 100, and the signal strength of the cellular signal received by the electronic device 100 through its antenna is greater than a first threshold, then the electronic device 100 will prompt the user whether to switch to the cellular network. This ensures that the electronic device 100 only switches to the cellular network when the cellular signal is strong.

[0225] For example, electronic device 100 can display FIG. 3CThe prompt message 320 shown includes the text "Cellular signal detected, do you want to switch to cellular network?". The prompt message 320 is used to prompt the user whether to switch to cellular network. The prompt message 320 also includes a yes option 3201 and a no option 3202. The user can confirm the switch to cellular network by using the yes option 3201, or the user can continue to maintain the satellite communication connection with satellite 200 by using the no option 3202 and not switch to cellular network.

[0226] For example, such as FIG. 3C As shown, the electronic device 100 can receive user input in response to option 3201 in the prompt information 320, such as a click operation. In response to the user's input, the electronic device 100 can display... FIG. 3D The displayed prompt message 330 includes the text "Cellular network switching...", which is used to inform the user that the electronic device 100 is switching to a cellular network.

[0227] After the electronic device 100 switches to the cellular network, the electronic device 100 can disconnect the satellite communication connection with the satellite 200.

[0228] like FIG. 3E As shown, after the electronic device 100 switches to a cellular network, the electronic device 100 can display... FIG. 3E The user interface 3310 is shown. User interface 3310 includes application icons for multiple applications. The user interface does not include a satellite live feed card 3102 to indicate that the electronic device 100 has disconnected its satellite communication connection with the satellite 200. User interface 3310 also includes a cellular network identifier 3301, which indicates the signal strength of the cellular network currently used by the electronic device 100, for example, a four-bar signal strength.

[0229] In some embodiments, when the electronic device 100 is equipped with multiple SIM cards, such as SIM card 1 and SIM card 2, and SIM card 1 and SIM card 2 correspond to the same cellular signal type, when the electronic device 100 detects that the signal type of the cellular signal received by the antenna is also the same as the cellular signal type corresponding to SIM card 1 and SIM card 2, the electronic device 100 can simultaneously display the signal strength of the cellular network corresponding to SIM card 1 and SIM card 2.

[0230] like FIG. 3F As shown, after the electronic device 100 switches to a cellular network, the electronic device 100 can display... FIG. 3FThe user interface 3410 is shown. User interface 3410 includes application icons for multiple applications. The user interface does not include a satellite liveness card 3102 to indicate that the electronic device 100 has disconnected its satellite communication connection with satellite 200. User interface 3410 also includes cellular network identifiers 3401 and 3402, wherein cellular network identifier 3401 indicates the signal strength of the cellular network corresponding to SIM card 1, and cellular network identifier 3402 indicates the signal strength of the cellular network corresponding to SIM card 2. The signal strength of both the cellular network corresponding to SIM card 1 and the cellular network corresponding to SIM card 2 is four bars.

[0231] In some embodiments, when the electronic device 100 is equipped with multiple different SIM cards, such as SIM card 1 and SIM card 2, and SIM card 1 and SIM card 2 correspond to different cellular signal types, when the electronic device 100 detects that the cellular signal types received by the antenna also include multiple types, and the multiple cellular signal types respectively match the cellular signal types corresponding to SIM card 1 and SIM card 2 installed on the electronic device 100, the electronic device 100 can also prompt the user to select one or more cellular networks to switch to.

[0232] For example, such as FIG. 3G As shown, electronic device 100 can display FIG. 3G The prompt message 350 shown includes the text "Multiple cellular signals detected, please select a cellular network to switch to." The prompt message 350 is used to inform the user of the type of cellular network to switch to. The prompt message 350 also includes options 3501, 3502, and 3503. The user can switch to the China Mobile cellular network through option 3501, switch to the China Unicom cellular network through option 3502, or switch to both China Mobile and China Unicom cellular networks simultaneously through options 3501 and 3502.

[0233] For example, such as FIG. 3H As shown, the user can select options 3501 and 3502. Then, the electronic device 100 can receive the user's input operation for option 3503 in the prompt information 350, such as a click operation. In response to the user's input operation, the electronic device 100 can confirm that it has switched to both the mobile cellular network and the Unicom cellular network at the same time.

[0234] In response to simultaneously switching between mobile cellular networks and Unicom cellular networks, electronic device 100 can display a similar... FIG. 3FThe user interface 3410 is shown, and cellular network identifiers 3401 and 3402 are displayed in the user interface 3410. Cellular network identifier 3401 is used to indicate the signal strength corresponding to the mobile cellular network, and cellular network identifier 3402 is used to indicate the signal strength corresponding to the China Unicom cellular network.

[0235] Optionally, the aforementioned mobile cellular network and China Unicom cellular network are used only to explain this application and do not constitute a limitation.

[0236] Optional, FIG. 3A-FIG. 3H The illustration shows that when the electronic device 100 displays its desktop, it prompts the user whether to switch to cellular network. In other embodiments, the electronic device 100 may also prompt the user whether to switch to cellular network when displaying the user interface of other applications. FIG. 3A-FIG. 3E This is merely an illustrative example and is not intended to be limiting.

[0237] FIG. 4 The diagram illustrates a process flow whereby, after establishing a satellite communication connection between the electronic device 100 and the satellite 200, the electronic device 100 prompts the user whether to switch to a cellular network.

[0238] FIG. 4 The modules involved in the embodiments may include those described above. FIG. 1C The image shows the satellite settings application, cellular modem, and Vendor-RIL. The cellular modem also includes a satellite communication modem (Modem) 18.

[0239] like FIG. 4 As shown, after the electronic device 100 establishes a satellite communication connection with the satellite 200, the interaction process in which the electronic device 100 prompts the user whether to switch to the cellular network internal module may include the following steps:

[0240] S401, Satellite communication modem 18 establishes a satellite communication connection with satellite 200.

[0241] In some embodiments, when the electronic device 100 is in an area without cellular network coverage, the electronic device 100 can also receive user operations to establish a satellite communication connection with the satellite 200, so that the electronic device 100 can communicate with other devices through the satellite 200.

[0242] Optionally, when electronic device 100 establishes a satellite communication connection with satellite 200, the satellite communication modem 18 in electronic device 100 is powered on.

[0243] Depend on FIG. 1GAs shown in the software architecture of the electronic device 100, the cellular modem includes a satellite modem 18, and the Vendor-RIL includes a satellite interface layer. The cellular modem can interact with upper-layer functional modules or applications through the Vendor-RIL, and the satellite modem 18 can also interact with upper-layer functional modules or applications through the satellite interface layer. The cellular modem and the satellite modem 18 can communicate with each other. For example, when the communication state between the electronic device 100 and the satellite is idle, the satellite modem can send a first command to the cellular modem. The first command instructs the cellular modem to receive cellular signals and detect the cellular signal type and / or cellular signal strength to confirm whether to switch to the cellular network. Upon confirming that the satellite communication connection has been disconnected, the cellular modem can also send a second command to the satellite modem, which instructs the satellite modem to disconnect from the satellite.

[0244] S402. Cellular modem detects the type of cellular signal received by the antenna.

[0245] Optionally, the type of cellular signal received by the antenna may include one or more, such as mobile cellular signals, China Unicom cellular signals, China Telecom cellular signals, etc.

[0246] In some embodiments, after the satellite communication modem 18 establishes a satellite communication connection with the satellite 200, the cellular modem is powered on and can periodically / irregularly / at certain intervals detect the signal type of the cellular signal received by the antenna.

[0247] For example, a certain duration could be 5ms, where the cellular modem checks the signal type of the cellular signal received by the antenna every 5ms.

[0248] Optionally, the electronic device 100 may also detect the signal type of the cellular signal received by the antenna on the electronic device 100 when it is in a busy state, and the electronic device 100 may also detect the signal type of the cellular signal received by the antenna on the electronic device 100 when it is in an idle state. This application does not limit this.

[0249] The term "electronic device 100 is in an idle state" can mean that there is no data to be transmitted between electronic device 100 and satellite 200. For example, electronic device 100 has no data to send to satellite 200, nor does it need to receive data from satellite 200.

[0250] The term "busy" for electronic device 100 can mean that there is data to be transmitted between electronic device 100 and satellite 200. For example, electronic device 100 may be sending data to satellite 200 or is currently sending data to satellite 200, or electronic device 100 may need to receive data from satellite 200 or is currently receiving data from satellite 200.

[0251] For example, "electronic device 100 is busy" could mean that electronic device 100 has established a satellite call with electronic device 400 via satellite 200, or it could mean that electronic device 100 is sending SMS messages to other devices via satellite 200, or it could mean that electronic device 100 is receiving SMS messages from other devices via satellite 200, etc.

[0252] For example, electronic device 100 being in an idle state can mean that electronic device 100 has not established a satellite communication with satellite 200, for example... FIG. 3A-3H The electronic device 100 shown only established a satellite communication connection with satellite 200, and did not establish a satellite call connection with other electronic devices through satellite 200. Alternatively, it could mean that electronic device 100 did not send SMS messages to other devices through satellite 200, or that electronic device 100 did not receive SMS messages sent by other devices through satellite 200, etc.

[0253] In some embodiments, the electronic device 100 is in an idle state, which may also refer to the satellite communication connection of the electronic device being in an idle state.

[0254] When the satellite communication connection of the electronic device is idle, the satellite modem 18 can send a first instruction to the cellular modem. This first instruction instructs the cellular modem to begin receiving cellular signals and to detect the cellular signal type and / or cellular signal strength. Upon confirming that the cellular signal type is the same as that in the electronic device 100 and / or the cellular signal strength is greater than a first threshold, the cellular modem can switch to the cellular network. If the user confirms the switch to the cellular network, the cellular modem can also send a second instruction to the satellite modem 18, instructing the satellite modem 18 to disconnect from the satellite 200.

[0255] Optionally, upon receiving the first instruction, the cellular modem can send a first message to the first application via the Vendor-RIL. This first message instructs the first application to display a prompt message asking the user whether to switch to the cellular network. If the user confirms the switch to the cellular network, the first application can send a second message to the cellular modem via the Vendor-RIL. In response to the second message, the cellular modem can send a second instruction to the satellite modem 18, instructing the satellite modem 18 to disconnect from the satellite 200. Upon receiving the second message, the cellular modem can switch to the cellular network. Upon receiving the second instruction, the satellite modem 18 can disconnect from the satellite 200.

[0256] Optionally, the terms "electronic device 100 is in an idle state" and "electronic device 100 is in a busy state" can also include other interpretations, which are not limited in this application.

[0257] S403. The cellular modem needs to confirm whether the cellular signal type is the same as the cellular signal type in the electronic device 100.

[0258] After acquiring the cellular signal received by the antenna, the cellular modem can detect the signal type of the cellular signal received by the antenna.

[0259] The types of cellular signals received by the antenna can include, but are not limited to, any one or more of the following: mobile cellular signals, China Unicom cellular signals, China Telecom cellular signals, etc.

[0260] The cellular modem can also obtain the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100.

[0261] The cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100 may include, but is not limited to, any one or more of the following: mobile cellular signal, China Unicom cellular signal, China Telecom cellular signal, etc.

[0262] In some embodiments, multiple SIM cards or multiple eSIM cards may be installed on the electronic device 100, and the cellular signal types corresponding to the multiple SIM cards or multiple eSIM cards may be the same or different.

[0263] After obtaining the signal type of the cellular signal received by the antenna, the cellular modem can confirm whether the signal type of the cellular signal received by the antenna is the same as the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100.

[0264] In some embodiments, when the electronic device 100 is equipped with multiple different SIM cards or eSIM cards, and the different SIM cards or eSIM cards correspond to different cellular signal types, when the electronic device 100 detects that the cellular signal types received by the antenna also include multiple types, and the multiple cellular signal types are respectively the same as the cellular signal types corresponding to the multiple SIM cards or multiple eSIM cards installed on the electronic device 100, then the electronic device 100 can also switch to connect to multiple different types of cellular networks at the same time.

[0265] If the cellular signal type received by the antenna is the same as the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100, the cellular modem can switch to the cellular network and execute S404.

[0266] If the cellular signal type received by the antenna is different from the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100, the cellular modem cannot switch to the cellular network, and S415 is executed.

[0267] S404, Cellular Modem Detection Antenna: Detects the strength of the cellular signal received by the antenna.

[0268] Optionally, the cellular modem can periodically / irregularly / at regular intervals detect the signal strength of the cellular signal received by the antenna.

[0269] For example, a certain duration could be 5ms, where the cellular modem checks the signal strength of the cellular signal received by the antenna every 5ms.

[0270] Optionally, if the antenna receives multiple types of cellular signals, the cellular modem can detect the cellular signal strength corresponding to each of the multiple types of cellular signals.

[0271] In some embodiments, if it is confirmed that the cellular signal type is the same as the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100, the cellular modem can detect the signal strength of the cellular signal received by the antenna before switching to the cellular network. If the signal strength of the cellular signal received by the antenna is greater than a first threshold, the user will be prompted whether to switch to the cellular network. This ensures that the electronic device 100 switches to the cellular network only when the cellular signal is strong.

[0272] Optionally, the electronic device 100 may also detect the signal strength of the cellular signal received by the antenna on the electronic device 100 when it is in a busy state, and the electronic device 100 may also detect the signal strength of the cellular signal received by the antenna on the electronic device 100 when it is in an idle state. This application does not limit this.

[0273] For an explanation of whether the electronic device 100 is in a busy or idle state, please refer to the description in S402.

[0274] S405. Cellular modems need to confirm whether the cellular signal strength is greater than the first threshold.

[0275] By acquiring the signal strength of the cellular signal received by the antenna, the cellular modem can determine whether the cellular signal strength is greater than a first threshold.

[0276] If the signal strength of the cellular signal received by the antenna is greater than the first threshold, it means that the cellular signal is good. The cellular modem can prompt the user at the application layer whether to switch to the cellular network, that is, execute S406-S414.

[0277] If the signal strength of the cellular signal received by the antenna is less than the first threshold, it means that the cellular signal is poor. The cellular modem can execute S415 without prompting the user whether to switch to the cellular network.

[0278] Optionally, S404 and S405 can be omitted.

[0279] S406, The cellular modem sends the first message to the Vendor-RIL.

[0280] The first message is used to prompt the user via the first application whether to switch to cellular network.

[0281] For example, the first application could be a system settings application or a satellite equipment application.

[0282] S407, Vendor-RIL sends the first message to the satellite setup application.

[0283] Depend on FIG. 1C As can be seen from the software architecture of the electronic device 100, the Vendor-RIL includes a satellite interface layer (Satellite-RIL). When the satellite communication modem 18 establishes a satellite communication connection with the satellite 200, the satellite interface layer (Satellite-RIL) is powered on, and the Vendor-RIL is also powered on.

[0284] Optionally, the first message can also be sent to the satellite setup application via the Satellite Interface Layer (Satellite-RIL).

[0285] S408, In response to the first message, the satellite settings application prompts the user whether to switch to cellular network.

[0286] If the cellular modem confirms that the signal type of the cellular signal received by the antenna is the same as the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100, the cellular modem can send a first message to the Vendor-RIL. The Vendor-RIL then sends a first message to the satellite settings application. In response to the first message, the satellite settings application can prompt the user whether to switch to the cellular network.

[0287] Optionally, if the cellular modem confirms that the signal type of the cellular signal received by the antenna is the same as the cellular signal type corresponding to the SIM card or eSIM card installed on the electronic device 100, and the signal strength of the cellular signal received by the antenna is greater than the first threshold, the cellular modem then sends the first message to the Vendor-RIL.

[0288] In some embodiments, the satellite settings app prompts the user whether to switch to cellular network, which may be a display FIG. 3C The displayed message is 320.

[0289] In some embodiments, when the electronic device 100 has multiple different SIM cards installed, such as SIM card 1 and SIM card 2, and SIM card 1 and SIM card 2 correspond to different cellular signal types, and when the electronic device 100 detects that the cellular signal types received by the antenna also include multiple types, and these multiple cellular signal types respectively match the cellular signal types corresponding to SIM card 1 and SIM card 2 installed on the electronic device 100, the electronic device 100 can also prompt the user to select one or more cellular networks to switch to. The satellite settings application prompts the user whether to switch to a cellular network, which may be a display... FIG. 3G The displayed prompt message is 350. Similarly, the implementation of multiple eSIM cards is similar to that of multiple SIM cards.

[0290] After prompting the user whether to switch to the cellular network, and if the user confirms the switch to the cellular network, the electronic device 100 executes S409-S412.

[0291] After prompting the user whether to switch to the cellular network, if the user confirms that they do not want to switch to the cellular network, the electronic device 100 executes S413-S415.

[0292] Optionally, to avoid data transmission failure caused by the electronic device 100 switching to the cellular network when transmitting data between the electronic device 100 and the satellite 200, the electronic device 100 may prompt the user whether to switch to the cellular network when it is in an idle state.

[0293] For an explanation of why electronic device 100 is in an idle state, please refer to the description in S402.

[0294] S409, The satellite settings application sends a second message to Vendor-RIL.

[0295] The second message is used to notify the cellular modem that it has agreed to switch to the cellular network.

[0296] S410 and Vendor-RIL send a second message to the cellular modem.

[0297] S411. In response to the second message, the satellite communication modem 18 disconnects the satellite communication connection with the satellite 200.

[0298] S412, In response to the second message, the cellular modem establishes a cellular network connection with the base station 300.

[0299] For example, confirming a user's action to switch to a cellular network could be... FIG. 3C The input action shown in prompt message 320 is for option 3201, such as a click action.

[0300] After confirming the switch to the cellular network, the satellite settings app can send a second message to the Vendor-RIL. The Vendor-RIL then sends a second message to the cellular modem.

[0301] After receiving the second message, the cellular modem can establish a cellular network connection with the base station 300.

[0302] Upon receiving the second message, the satellite communication modem 18 in the cellular modem can disconnect the satellite communication connection from the satellite 200.

[0303] Optionally, upon receiving the second message, the cellular modem can send a second command to the satellite modem 18, instructing the satellite modem 18 to disconnect its satellite communication connection with the satellite 200. In response to the second command, the satellite modem 18 can disconnect its satellite communication connection with the satellite 200.

[0304] Optionally, after the satellite communication modem 18 disconnects from the satellite 200, the satellite communication modem 18 can be in a power-off state or a power-on state, and this application does not limit this.

[0305] After the satellite communication modem 18 disconnects from the satellite 200, the cellular modem remains powered on, allowing the electronic device 100 to establish a cellular network connection with the base station 300 through the cellular modem, thus enabling the electronic device 100 to use the cellular network.

[0306] For example, such as FIG. 1H As shown, after receiving the second message, satellite modem 18 disconnects from satellite 200. After the cellular modem establishes a cellular network connection with base station 300, the cellular modem can interact with upper-layer functional modules or applications through Vendor-RIL. When electronic device 100 needs to communicate with base station 300, the application layer of electronic device 100 can send cellular communication data to Vendor-RIL, which then sends the cellular communication data to the cellular modem. Finally, the cellular modem sends the cellular communication data to base station 300, which then sends the cellular communication data to other electronic devices. Similarly, base station 300 can receive cellular communication data sent by other electronic devices, which then sends the cellular communication data to the cellular modem, which then sends the cellular communication data to Vendor-RIL, and finally, the Vendor-RIL sends the cellular communication data to the application layer of electronic device 100.

[0307] S413, The satellite settings application sends a third message to Vendor-RIL.

[0308] The third message is used to instruct the cellular modem that the user should not switch to the cellular network.

[0309] S414, Vendor-RIL sends a third message to the cellular modem.

[0310] S415, satellite communication modem 18 and satellite 200 continue to maintain satellite communication connection.

[0311] For example, confirming that a user does not switch to a cellular network could be... FIG. 3C The input action shown is for the "No" option 3202 in the prompt message 320, such as a click action.

[0312] After confirming that the switch will not go to the cellular network, the satellite settings app can send a third message to the Vendor-RIL. The Vendor-RIL then sends a third message to the cellular modem.

[0313] Upon receiving the third message, the satellite communication modem 18 in the Vendor-RIL can continue to maintain a satellite communication connection with the satellite 200.

[0314] Optionally, after receiving the third message, the satellite communication modem 18 in Vendor-RIL remains powered on, as does the cellular modem.

[0315] Optionally, after receiving the third message, i.e., confirming that the user is not currently switching to a cellular network, the cellular modem can stop detecting the cellular signal type and the cellular signal strength to save power consumption of the electronic device 100.

[0316] Optionally, after receiving the third message and stopping the detection of cellular signal type and cellular signal strength, if the electronic device 100 disconnects from and reconnects to the satellite 200, the cellular modem can detect the cellular signal type and cellular signal strength again and restart the process. FIG. 4 The method provided in the embodiment prompts the user whether to switch to cellular network.

[0317] In some embodiments, after prompting the user whether to switch to the cellular network and confirming that the user does not want to switch to the cellular network, the electronic device 100 may not execute S413-S414, and this application does not limit this.

[0318] For example, such as FIG. 1G As shown, after receiving the third message, satellite modem 18 maintains its satellite communication connection with satellite 200. Satellite modem 18 can interact with upper-layer functional modules or upper-layer applications through Vendor-RIL or the satellite interface layer. When electronic device 100 needs to communicate with satellite 200, the application layer of electronic device 100 can send satellite communication data to Vendor-RIL or Satellite-RIL within Vendor-RIL. Vendor-RIL or Satellite-RIL within Vendor-RIL then sends the satellite communication data to the satellite modem within the cellular modem. Finally, the satellite modem within the cellular modem sends the satellite communication data to satellite 200, and satellite 200 then sends the satellite communication data to other electronic devices. Similarly, satellite 200 can receive satellite communication data sent by other electronic devices, and then satellite 200 sends the satellite communication data to the satellite modem in the cellular modem. The satellite modem in the cellular modem then sends the satellite communication data to the Vendor-RIL or the Satellite-RIL in the Vendor-RIL. Finally, the Vendor-RIL or the Satellite-RIL in the Vendor-RIL sends the satellite communication data to the application layer of electronic device 100.

[0319] Using this method, after establishing a satellite communication connection with the satellite 200, the electronic device 100 can automatically detect cellular signals near the electronic device 100 and prompt the user to switch to the cellular network after detecting the cellular signal. This eliminates the need for the user to manually close the satellite communication connection and then switch to the cellular network, saving user time and improving the user experience.

[0320] FIG. 5 A flowchart illustrating a communication method provided in this application is shown.

[0321] S501, The electronic equipment has established a satellite communication connection with the satellite.

[0326] For example, the second cellular signal type in the electronic device is the cellular signal type corresponding to the SIM card in the electronic device or the cellular signal type corresponding to the eSIM card in the electronic device.

[0327] S504. If the first cellular signal type is the same as the second cellular signal type in the electronic device, the electronic device prompts the user whether to switch to the first cellular network.

[0328] For example, the prompt message could be FIG. 3C The displayed message is 320, or FIG. 3G The displayed message is 350.

[0329] S505, the electronic device receives and responds to the user's first operation, disconnects the satellite communication connection with the satellite, and switches to the first cellular network.

[0330] Using this method, after the electronic device establishes a communication connection with the satellite, the electronic device can detect the first cellular signal type of the received cellular signal, and if the first cellular signal type is the same as the second cellular signal type in the electronic device, the electronic device prompts the user to switch to the cellular network.

The first indicator is used to indicate the connection status between the first electronic device and the satellite, and the first prompt message is used to prompt the user to maintain or adjust the current posture of holding the first electronic device and aligning it with the satellite. Alternatively, the electronic device displays a first capsule, which includes the connection status between the first electronic device and the satellite. When the electronic device disconnects from the satellite communication connection via the satellite modem, the electronic device stops displaying the first card or the first capsule.
