[0020] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] Current terminals cannot support dual standby and dual communication for satellite and traditional calls. For example, if a user is using one SIM card for satellite calling, the other SIM card will be unable to initiate or receive calls, even if there is cellular network coverage. While radio frequency interference is a hardware issue, software design is even more crucial. Therefore, embedding satellite calling into terminals to achieve dual standby and dual communication for both satellite and traditional calls is a pressing technical challenge.

[0022] In one embodiment, traditional calls include but are not limited to cellular network calls, etc.

[0023] An embodiment of the present application provides a satellite call method. By introducing a satellite telecommunications service layer, a satellite call audio processing layer, etc. on a terminal integrated with a satellite communication chip, it can be compatible with traditional calls and satellite calls, achieve dual-standby and dual-communication call effects, and better integrate satellite calls into traditional terminal systems.

[0024] The following embodiments take the Android system as an example.

[0025] FIG1 is a flow chart illustrating a satellite call method according to an embodiment of the present invention. The method can be executed by a terminal (e.g., an Android terminal). In other words, the method can be executed by software or hardware installed on the terminal. As shown in FIG1 , the method can include the following steps.

[0026] S102: Acquire an outgoing call request based on the telephone management layer, where the outgoing call request includes a satellite call request or a traditional call request.

[0027] In one embodiment, before S102, the following step may be included: in response to a selection of a satellite call through a human-computer interaction interface, generating the outgoing call request. This embodiment can display information related to the satellite call service on the terminal's human-computer interaction interface (e.g., the call interface). This embodiment does not require a special design for the terminal's call interface; satellite calls can use a similar call interface as traditional calls, thereby simplifying the implementation.

[0028] S104: When it is determined that the outgoing call request is a satellite call request, a satellite call service is executed based on the satellite telecommunication service layer and the satellite call audio processing layer.

[0029] The satellite call audio processing layer is used to process audio data from the satellite chip protocol stack and provide audio data to the satellite chip protocol stack, and the audio data is audio data corresponding to the satellite call service.

[0030] In one embodiment, the satellite telecommunication service layer provides satellite calling accounts and the like for performing satellite calling services.

[0031] In one embodiment, the satellite call audio processing layer is used to process downlink audio data from the satellite chip protocol stack and provide uplink audio data to the satellite chip protocol stack.

[0032] The satellite call method provided in this embodiment has a main software architecture at the implementation level, as shown in Figure 2. This embodiment implements satellite call control by introducing a satellite telecommunications service layer and a satellite call audio processing layer. The call interface and call management logic can be shared with traditional calls or set up separately. Sharing can simplify the implementation, reduce the complexity of user operations, and improve the user experience.

[0033] As shown in Figure 3, the satellite chip protocol stack interacts with the terminal's Android system through the data port and the control port. Specifically, as shown in Figure 4, the satellite chip protocol stack can be adapted by the Hardware Abstraction Layer (HAL) and then connected to the terminal's Android system.

[0034] The satellite call method provided in the embodiment of the present application enables satellite calls to be better integrated into the traditional terminal system by introducing a satellite telecommunications service layer and a satellite call audio processing layer into the terminal, thereby achieving dual-standby and dual-communication call effects for satellite calls and traditional calls.

[0035] The satellite call method provided in the embodiment of the present application can achieve loose coupling between satellite call services and native systems, reduce destructive modifications to the native systems, and thus quickly achieve adaptation to various types of satellite chip solutions; from the software architecture, it can support dual standby and dual communication for satellite calls and traditional calls.

[0036] It is foreseeable that, combined with the current extremely high market coverage of smart mobile terminals, the miniaturized integration of satellite communications in smart mobile terminals will greatly empower smart terminals, enabling them to play a more important role in scenarios such as disaster relief, outdoor and remote area coverage.

[0037] In one embodiment, in S104, executing the satellite call service based on the satellite telecommunication service layer and the satellite call audio processing layer may include the following steps: the satellite telecommunication service layer notifies the satellite chip protocol stack of the outgoing call request through the satellite wireless access layer; and the satellite call audio processing layer receives audio data from the satellite chip protocol stack and sends audio data to the satellite chip protocol stack.

[0038] In one embodiment, the satellite call audio processing layer receives downlink audio data from the satellite chip protocol stack, and the downlink audio data may be from the other party of the call; and sends uplink audio data to the satellite chip protocol stack, and the uplink audio data may be audio data collected by this terminal.

[0039] In some examples, the satellite call audio processing layer can receive audio data from the satellite chip protocol stack and send audio data to the satellite chip protocol stack via the satellite wireless access layer. Whether the satellite call audio processing layer and the satellite chip protocol stack need to be connected to the satellite wireless access layer can be determined based on the specific implementation of the satellite chip protocol stack.

[0040] During satellite call service execution on a terminal, satellite call capabilities can be provided by an independent satellite chip protocol stack integrated into the system. According to general chip-level design principles, service flow control and interaction are generally provided by data and control ports, as shown in Figures 3 and 4. Therefore, the aforementioned outgoing call request can be transmitted via the control port, and the aforementioned audio data can be transmitted via the data port.

[0041] The above embodiments primarily describe the outgoing call process for satellite calls. The following describes the incoming call process for satellite calls. It is understood that the incoming call process can serve as a supplement to the outgoing call process and can also be implemented independently of the outgoing call process. In one embodiment, the satellite call method may further include the following steps: 1) upon receiving an incoming call request, the satellite chip protocol stack notifies the satellite telecommunications service layer of the incoming call request via the satellite wireless access layer; 2) the satellite telecommunications service layer notifies the telephone management layer of the incoming call request; and 3) executing the satellite call service based on the satellite telecommunications service layer and the satellite call audio processing layer. The specific execution process of the satellite call service may refer to S104.

[0042] In one embodiment, the satellite call method may further include the following steps: when the terminal initiates satellite access, the satellite telecommunications service layer sends a registration request to the satellite chip protocol stack; wherein the registration request is used to request notification events from the satellite chip protocol stack, and the notification events include at least one of the following: a notification event indicating whether satellite access is successful, and a paging event. For example, when the core network needs to establish a connection with the terminal, it initiates a paging process. In this case, the core network sends a paging message to the base station, and the base station can then send a paging message to the terminal through the paging process.

[0043] As shown in Figure 5, during the startup and registration phase of an Android terminal, the satellite telecommunications service layer initiates an event registration request to the satellite chip protocol stack through the satellite wireless access layer to obtain notification events indicating successful satellite access, paging events, and so on. Subsequently, the satellite chip protocol stack can send notifications to the satellite telecommunications service layer, such as notifications of successful satellite access, notifications of failed satellite access, paging messages, and incoming call requests.

[0044] This embodiment may further include the following steps: during the satellite access startup phase of the terminal, the satellite telecommunications service layer starts at least one of the following for the satellite call service: a satellite call account, a satellite wireless access layer, and a satellite telephone service layer.

[0045] As shown in Figure 6, during the satellite access startup phase of the terminal, the satellite telecommunications service layer starts the satellite call account, the satellite wireless access layer, and the satellite phone service layer to support the satellite call service. The satellite call account will be bound to the satellite phone service layer, so that the satellite phone service layer can determine the use of the satellite call service based on the satellite call account.

[0046] The satellite phone service layer is used for at least one of the following: determining whether the outgoing call request is a satellite call request or a traditional call request; and controlling the call state of the satellite call, which includes, for example, mute, hold, etc.

[0047] The satellite access phase mentioned in the above embodiments may include searching for satellites and registering with satellites. The satellite call account is used for at least one of the following in response to the results of searching for satellites and registering with satellites:

[0048] 1) In response to a selection operation on the satellite calling account, obtaining the satellite calling capability of the terminal and determining whether the terminal supports the satellite calling service.

[0049] 2) If the terminal supports the satellite call service, guiding the call initiated using the satellite call account to execute the satellite call service.

[0050] The software architecture of a satellite communication method provided in another embodiment of the present application is shown in FIG7 , including:

[0051] Satellite telecommunications service layer: can be used to provide satellite calling accounts. These satellite calling accounts are parallel to Android's ordinary calling accounts and provide a calling behavior control mechanism similar to traditional calling accounts, allowing users to make different types of calls by using different accounts.

[0052] This satellite call account is controlled by the results of satellite search and registration with the satellite, and simultaneously provides upward and downward behavior control: upward, through the satellite call account entrance that the user can select, the call dial pad obtains the terminal's satellite call capability through the satellite call account, and then determines whether the dial-up application can use the satellite call service; downward pointing to the satellite call service service layer, thereby guiding the call initiated using this satellite call account to use the satellite call service process.

[0053] The satellite phone service layer inherits from the Android phone framework base class and can coexist in the system as a satellite call. The core functional classes of this satellite phone service layer inherit from the Android native telecommunications framework base classes android.telecom.Connection and android.telecom.ConnectionService. It connects to the Satellite Radio Access Layer (Satellite RIL) to achieve the coexistence of the two layers with traditional calls.

[0054] The Satellite Call Audio Processing Layer, driven by the Satellite Telecom Service Layer, processes downlink voice data from the satellite chip protocol stack and simultaneously provides uplink audio data to the satellite chip protocol stack. To achieve duplex operation, the Satellite Call Audio Processing Layer uses two concurrent threads to process uplink and downlink audio data on the satellite link. Once the satellite call service is established, these two threads are triggered to work synchronously. The start, run, or termination of these two threads is controlled by user actions such as mute and hold.

[0055] The Satellite Wireless Access Layer interacts with the satellite chip protocol stack for related events, converting and encapsulating them into relevant interfaces for invocation by the Satellite Telecommunications Service Layer and the Satellite Call Audio Processing Layer. In some embodiments, the Satellite Wireless Access Layer may be part of the Satellite Telecommunications Service Layer; in some embodiments, the Satellite Wireless Access Layer may be independent of the Satellite Telecommunications Service Layer.

[0056] Based on the above software architecture design, in the call initiation scenario, the call initiation process is shown in Figure 8. The main interactions of the entire satellite call service are shown in Figure 9.

[0057] As shown in Figure 8, in the scenario of an outgoing call, after the Telecom telephone management layer receives the outgoing call request, it determines whether it is a satellite call request. If it is not a satellite call request (i.e., a traditional call request), it can subsequently use the PSTN account, Telephony, RIL, and modem to execute the traditional call process according to the existing technical process. If it is a satellite call request, it can use the satellite call account to execute the satellite call service based on the satellite telecommunications service layer, hardware abstraction layer, satellite chip protocol stack, etc.

[0058] As shown in Figure 9, the main interaction process of the entire satellite call service is as follows: During the system startup phase of the Android terminal, the satellite telecommunications service layer initiates an event registration request to the satellite chip protocol stack through the satellite wireless access layer in order to obtain notification events such as whether satellite access is successful and paging events.

[0059] In the outgoing call scenario of the satellite call service, the satellite telecommunications service layer notifies the business side of the satellite chip protocol stack of the outgoing call request through the satellite wireless access layer. At the same time, the satellite call audio processing layer receives audio data from the data side of the satellite chip protocol stack and sends audio data to the data side of the satellite chip protocol stack.

[0060] In the incoming call scenario of the satellite call service, the satellite chip protocol stack notifies the satellite telecommunications service layer of the outgoing call request through the satellite wireless access layer. At the same time, the satellite call audio processing layer receives audio data from the data plane of the satellite chip protocol stack and sends audio data to the data plane of the satellite chip protocol stack.

[0061] Corresponding to the satellite call method provided in the embodiment of the present application, the embodiment of the present application also provides a terminal including the following modules.

[0064] The terminal provided in the embodiment of the present application can realize the concurrency and coexistence of satellite call services and traditional call services by introducing a satellite telecommunications service layer and a satellite call audio processing layer, so that satellite calls can be better integrated into the traditional terminal system, achieving dual-standby and dual-communication call effects for satellite calls and traditional calls.

[0065] In one embodiment, the terminal further includes a satellite wireless access layer, wherein the satellite wireless access layer is connected to the satellite call audio processing layer and the satellite chip protocol stack. The satellite telecommunication service layer may be configured to notify the satellite chip protocol stack of the outgoing call request via the satellite wireless access layer, and the satellite call audio processing layer may be configured to receive audio data from the satellite chip protocol stack and send audio data to the satellite chip protocol stack.

[0067] As an embodiment, during the satellite access startup phase of the terminal, the satellite telecommunications service layer is also used to send a registration request to the satellite chip protocol stack; wherein the registration request is used to request a notification event from the satellite chip protocol stack, and the notification event includes at least one of the following: a notification event of whether the satellite access is successful, and a paging event.

[0068] As an embodiment, during the satellite access startup phase of the terminal, the satellite telecommunication service layer is further used to create at least one of the following for the satellite call service: a satellite call account, a satellite wireless access layer, and a satellite telephone service layer.

[0069] As an embodiment, the satellite telephone business service layer is used for at least one of the following: determining whether the outgoing call request is a satellite call request or a traditional call request; and controlling the call state of the satellite call.
