Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic technology, and in particular to a communication method, electronic equipment and system. Background Art

[0002] Currently, when a terminal device is in a call (referred to as a first call), if it receives a call request from another call (referred to as a second call), the user can choose to hang up or pause (also referred to as suspend) the first call.

[0003] If the user hangs up the first call, the user cannot return to the first call after hanging up, that is, the user needs to reconnect with the caller of the first call. In addition, in a conference call scenario, other users cannot add the user to the conference because the user is on another call. If the user pauses the first call, the first call will be interrupted by a prompt tone. For example, in a conference call scenario, other users will hear the prompt tone "The user you dialed is using the call hold service, please do not hang up...", which is a disturbance to others.

[0004] It can be seen that when the terminal device receives the call request for the second call, no matter the user hangs up or suspends the first call, the normal communication of the first call will be affected. Summary of the invention

[0088] The technical solutions in the embodiments of the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0089] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0090] The term "user interface (UI)" in the following embodiments of the present application refers to a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The user interface is a source code written in a specific computer language such as Java and extensible markup language (XML). The interface source code is parsed and rendered on an electronic device, and finally presented as content that can be recognized by the user. The commonly used form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0091] An embodiment of the present application provides a calling method. When a user makes a first call through a first terminal, if an incoming call signal of a second call is received, the incoming call signal can be answered through the second terminal and the second call can be made with the help of the second terminal. This method can improve the calling experience.

[0092] The call described in the embodiments of the present application may refer to a call transmitted through the traditional telephone network of a telecommunications operator (referred to as a basic call in the embodiments of the present application), or may be a voice transmission (Voice over Internet Protocol, VoIP) call based on IP (Internet Protocol) transmitted via the Internet. It should be noted that the basic call may also be referred to as a traditional call or a traditional phone call, etc., which is not limited in the embodiments of the present application.

[0176] Figure 4A The schematic diagram of the dual-SIM dual-pass scenario is shown as an example. Figure 4A As shown, the scenario includes a first terminal and a second terminal, and the first terminal is installed with two SIM cards. Figure 4A The example shows that the two SIM cards are SIM cards of different operators, namely, the SIM card of operator 1 (referred to as SIM1 or card 1) and the SIM card of operator 2 (referred to as SIM2 or card 2). Then, the first terminal can access the network of operator 1 (referred to as operator network 1) based on SIM1 to achieve communication with other terminal devices, and access the network of operator 2 (referred to as operator network 2) based on SIM2 to achieve communication with other terminal devices.

[0177] Assuming that the user of the first terminal is the first user, the first user can use the first terminal to receive or make calls through SIM1.

When the first terminal is in the SIM1 call process, if the first terminal receives an incoming call signal from the operator network 2, the incoming call signal can be sent to the second terminal; the first user can answer or hang up the incoming call signal at the second terminal. Figure 4A The example shows that the first user answers the incoming call signal through the second terminal, and the first terminal can realize the second call through the second terminal, that is, the call made through SIM2 ( Figure 4A SIM2 call in the system).

In the dual-SIM dual-channel scenario, the two SIM cards installed in the first terminal may also be SIM cards of the same operator, which is not limited in the embodiments of the present application.

Then, the first terminal can access the network of operator 1 (referred to as operator network 1) based on SIM1 to achieve communication with other terminal devices.

[0180] Assuming that the user of the first terminal is the first user, when the first terminal is in a call of SIM1 (referred to as the first call of SIM1), if the first terminal receives an incoming call signal from operator network 1, the incoming call signal can be sent to the second terminal; the first user can answer or hang up the incoming call signal at the second terminal. Figure 4B The example shows that the first user answers the incoming call signal through the second terminal, and the first terminal can realize the second call through the second terminal, that is, the second call through SIM1 ( Figure 4B The first call is referred to as SIM1 in the example).

Figure 4C As shown, the scenario includes a first terminal and a second terminal, the first terminal is installed with a SIM card, Figure 4C The example shows that the SIM card is a SIM card of operator 1 (referred to as SIM1). Then, the first terminal can access the operator network based on SIM1 to achieve communication with other terminal devices. The operator network can also provide VoIP calls for the first terminal.

[0182] Assuming that the user of the first terminal is the first user, when the first terminal is in a call of SIM1 (referred to as SIM1 call), if the first terminal receives an incoming call signal from the VoIP call, the incoming call signal can be sent to the second terminal; the first user can answer or hang up the incoming call signal at the second terminal. Figure 4C The example shows that the first user answers the incoming call signal through the second terminal, and the first terminal can realize a second call, ie, a VoIP call, through the second terminal.

[0190] It should be noted that the above-mentioned call object information 511 may also include the operator to which the SIM card of the call object belongs; the above-mentioned SIM card identification 511C may also be the icon of card 1 and the operator name of card 1. The embodiment of the present application does not limit the form of the SIM card identification in the user interface. For the convenience of description, the text "Card 1" or "Card 2" is used for illustrative purposes below.

[0191] The related control area 512 exemplarily shows a video call control, a mute control, and a contact control. The related control area 512 may also include a recording control, etc., which is not shown. The embodiment of the present application does not limit this. The dial key 513 is used to display the dial keyboard; the hang-up control 514 is used to hang up the current call, and the speaker control 515 is used to switch the microphone or speaker to play the downlink audio.

[0192] Assume that the first terminal receives a call request from Jane for card 2 when the first terminal is in a call with Bob based on card 1. The first terminal may display the following information: Figure 5B The user interface 52 shown in FIG. 1 and the second terminal is controlled to display the Figure 5C The user interface 53 shown. Wherein, card 2 is another SIM card installed in the first terminal except card 1, and the second terminal is a device that establishes a communication connection with the first terminal.

[0193] The user interface 52 displayed by the first terminal may include first call information 520 , second incoming call information 521 , a SIM card identifier 522 corresponding to the second call, a text message control 523 , a reminder control 524 , a hang-up control 525 , and an answer control 526 .

[0194] The first call information 520 may include a SIM card identifier 520A corresponding to the first call, a call object name 520B of the first call, a call duration 520C of the first call, a hang-up control 520D, and an expansion control 520E. The hang-up control 520D is used to hang up the first call, and the expansion control 520E is used to expand or collapse the first call information 520. For example, when the current first call information 520 is in an expanded state and the second incoming call information 521 is in a collapsed state, the SIM card identifier 521A, the call object name 521B, the call duration 521C, etc. may be invisible. Figure 5B The example shows that the call duration 520C of the first call is 01:06. It should be understood that the call duration 520C of the first call changes with time.

[0195] The second incoming call information 521 may include a call recipient name 521A, a call recipient address 521B, and a SIM card identifier 521C. Figure 5A The example shows that the call object name 521A is "Jane", and Jane can be the name note of the number on the first terminal; the example shows that the call object's address 521B is "Shenzhen, Guangdong", and the SIM card identifier 521C is "Card 2".

[0196] It should be noted that the second incoming call information 521 may also include the operator of the caller's SIM card; the SIM card identifier 521C may also be the icon of card 2 and the operator name of card 2, which is not limited in this embodiment of the present application. Figure 5B The example shows that the SIM card identifier 522 corresponding to the second call is Card 2. The SIM card identifier 522 may also be an icon of Card 2 and the operator name of Card 2, which is not limited in this embodiment of the present application.

[0197] Among them, the SMS control 523 is used to send a text message to the caller of the second call; the reminder control 524 is used to create a call back reminder; the hang-up control 525 is used to reject the incoming call of the second call; and the answer control 526 is used to answer the incoming call of the second call.

[0198] Assume that the first terminal receives a call request from Jane for card 2 when the first terminal is in a call with Bob based on card 1. The first terminal can send the call request to the second terminal and display the following information: Figure 5B The user interface 52 shown; further, the second terminal responds to the call request, and can synchronously display the following Figure 5C User interface 53 is shown.

[0199] The user interface 53 displayed by the second terminal may include the name 531A of the call object, the location 531B of the call object, a hang-up control 532 and an answer control 533. The hang-up control 532 is used to reject the call; the answer control 533 is used to connect the call. Figure 5B The example shows that the name 531A of the call object is "Jane" and the location 531B of the call object is "Shenzhen, Guangdong." The location 531B of the call object may be the location of the SIM card of the call object of the second call.

[0200] In some other embodiments of the present application, assuming that the user clicks the hang-up control 532, the second terminal may send a rejection command to the first terminal, and the first terminal, in response to the rejection command, refuses to establish the second call; the first terminal may display a prompt message, for example, the prompt message may be "The watch has rejected the call from Jane."

[0201] like Figure 5C As shown, when the second terminal detects the user operation on the answering control 533, it can respond to the user operation and display the following Figure 5D The user interface 54 shown in FIG. 5 includes the name of the caller 541A, the call time 541B, a mute control 542, a hang-up control 543, and a speaker control 544. The mute control 542 is used to turn off the microphone; the hang-up control 543 is used to end the current call; and the speaker control 544 is used to switch between the microphone and the speaker to play the downlink audio.

[0202] like Figure 5C As shown, when the second terminal detects a user operation on the answer control 533, it can also respond to the user operation and send an answer command to the first terminal. Correspondingly, the first terminal responds to the answer command and displays the following Figure 5E User interface 55 is shown.

[0203] The user interface 55 may include first call information 550, second call information 551, related control area 552, dial key 553, hang up control 554 and speaker control 555. The first call information 550 may refer to the related introduction of the first call information 520, and the related control area 552 may refer to the related introduction of the related control area 512.

[0204] The second call information 551 may include a SIM card identifier 551A corresponding to the second call, a call object name 551B of the second call, answering device information 551C, a hang-up control 551D, and an expansion control 551E. The hang-up control 551D is used to hang up the second call, and the expansion control 551E is used to expand or collapse the second call information 551. For example, the current second call information 551 is in an expanded state. When the second call information 551 is in a collapsed state, the SIM card identifier 551A and the call object name 551B of the second call may be invisible. Figure 5B The example shows that the SIM card identifier 551A corresponding to the second call is "Card 1", and the caller name 551B of the second call is "Jane"; the answering device information 551C is "Watch answering", and it should be understood that if the answering device is other devices, the answering device information 551C can be displayed as other information, such as "smart glasses answering".

[0205] The dial key 553 is used to display the dial keyboard; the hang-up control 554 is used to hang up the first call, and the speaker control 555 is used to switch the microphone or the loudspeaker to play the downlink audio of the first call.

[0206] (II) Single-SIM dual-pass scenario

[0207] Next, through Figure 5A , Figure 5C , Figure 5D as well as Fig. 6A , Figure 6B Introduce the single card dual pass process of the first terminal and the second terminal (such as Figure 4B The user interface in the scenario shown in FIG. Figure 5A , Fig. 6A , Figure 6B is a user interface implemented on the first terminal, Figure 5C and Figure 5D It is a user interface implemented on the second terminal.

[0208] Assuming that the first user is talking to Bob using the first terminal based on card 1, the electronic device may display the following information: Figure 5A Further, when the first terminal receives a call request for a basic call from Jane, the first terminal may display the following Fig. 6A The user interface 61 shown in FIG. 61 and sends the call request to the second terminal; further, the second terminal may respond to the call request by displaying Figure 5C User interface 53 is shown.

[0209] The user interface 61 displays first call information 610, second incoming call information 612, a SIM card identifier 611 corresponding to the second call, a text message control 613, a reminder control 614, a hang-up control 615, and an answer control 616. The second incoming call information 612 may include a call object name 612A, a call object address 612B, and a SIM card identifier 612C. Figure 5A The example shows that the call object name 612A is "Jane", and Jane can be the name note of the number on the first terminal; the example shows that the call object's address 612B is "Shenzhen, Guangdong", and the SIM card identifier 612C is "Card 1".

[0210] The difference between user interface 61 and user interface 52 may be that: the SIM card identifier 611 corresponding to the second call in user interface 61 is "Card 1", while the SIM card identifier 522 corresponding to the second call in user interface 52 is "Card 2"; and, the SIM card identifier 612C in user interface 61 is "Card 1", while the SIM card identifier 521C in user interface 52 is "Card 2".

[0211] It should be understood that, in order to facilitate the introduction of the difference between the dual-SIM dual-talk scenario and the dual-SIM dual-talk scenario, the above embodiment is exemplified by the user interface in which the first user answers a call from user Jane through a different card while talking with Bob based on card 1. In the dual-SIM dual-talk scenario, user "Jane" calls the first user's card 2, and in the single-SIM dual-talk scenario, user "Jane" calls the first user's card 1.

[0212] like Figure 5C As shown, when the second terminal detects the user operation on the answering control 533, it can respond to the user operation and display the following Figure 5D The user interface 54 shown in FIG. 54 may also respond to the user operation by sending a call-answering command to the first terminal. Accordingly, the first terminal responds to the call-answering command by displaying a Figure 6B User interface 62 is shown.

[0213] Exemplarily, the difference between the user interface 62 and the user interface 55 is that the specific content of the second call information is different, the specific content of the second call information displayed by the user interface 55 is the second call information 551, and the specific content of the second call information displayed by the user interface 62 is the second call information 620. Specifically, the difference between the second call information 620 and the second call information 551 at least includes that the SIM card identifiers corresponding to the second call are different, the SIM card identifier 551A corresponding to the second call is "card 2", and the SIM card identifier 620A corresponding to the second call is "card 1".

[0214] (III) Basic call and VoIP call dual-channel scenario

[0215] Next, through Figure 5A , Figure 5D as well as Figure 7A-7C Describes the dual-communication scenarios of the first terminal and the second terminal in basic calls and VoIP calls (such as Figure 4C The user interface in the scenario shown in FIG. Figure 5A , Figure 7B , Figure 7C is a user interface implemented on the first terminal, Fig. 7A and Figure 5D It is a user interface implemented on the second terminal.

[0216] Assuming that the first user is talking to Bob using the first terminal based on card 1, the electronic device may display the following information: Figure 5A The user interface 51 shown in FIG. 5 is shown in FIG. 5. Further, the first terminal receives a VoIP call from Jane via a VoIP application (such as Changlian), and the first terminal may display the following information: Fig. 7AThe user interface 71 shown in FIG. 1 and the call request is sent to the second terminal; further, the second terminal may respond to the call request by displaying a Figure 7B User interface 72 is shown.

[0217] The user interface 71 displays a call mark 710, second incoming call information 711, a hang-up control 712, and an answer control 713. The second incoming call information 711 may include a call object avatar 711A, a call object name 711B, and an application call mark 711C. Figure 5A The example shows that the call object name 711B is "Jane" and the application call identifier 711C is "Changlian Voice". Jane can be the name of the call object in the Changlian application on the first terminal. The hang-up control 712 is used to reject the call; the answer control 713 is used to connect the call.

[0218] The user interface 72 displayed by the second terminal may include a name 721A of the call object, an application call identifier 721B, a hang-up control 722, and an answer control 723. The hang-up control 722 is used to reject the call; and the answer control 723 is used to connect the call. Figure 5B The example shows that the name 721A of the call object is "Jane" and the application call identifier 721B is "Changlian Voice".

[0219] like Figure 7B As shown, when the second terminal detects a user operation on the answering control 723, it can respond to the user operation and display the following Figure 5D User interface 54 is shown.

[0220] like Figure 7B As shown, when the second terminal detects a user operation on the answer control 723, it can also respond to the user operation and send an answer command to the first terminal. Correspondingly, the first terminal responds to the answer command and displays the following Figure 7C User interface 73 is shown.

[0221] The status bar of the user interface 73 includes a call indicator 730. For example, the call indicator 730 is "watch answering the call".

[0222] Exemplarily, the difference between the user interface 73 and the user interface 51 may include that the status bar of the user interface 73 is newly added with the call indicator 730 .

[0223] It should be understood that the above embodiment is illustratively described by taking the example of user "Jane" calling the first user's card 1 and card 2 and making a VoIP call to the first user through Changlian. In other embodiments of the present application, the users of the basic call and the VoIP call can be different users.

[0224] The following is based on Figure 1 The schematic diagram of the communication system shown in FIG. Figure 2 and Figure 3 The hardware and software structure diagram of the electronic device shown is combined with the above-mentioned scenarios and related interfaces to describe in detail the calling method provided in the embodiment of the present application.

[0225] Figure 8 The present invention exemplarily illustrates a call method process in a dual-SIM dual-communication scenario provided by an embodiment of the present application.

[0226] In the embodiment of the present application, the first terminal includes a first call application, a first communication framework, a first audio framework, a Modem and a HiFi module, and Figure 8 The first communication framework may include a microphone, a speaker, and a receiver, etc., which are not shown in the figure. Figure 3 The second terminal may include a second call application, a second communication framework, and a second audio framework, and Figure 8 Microphone, speaker, earpiece, etc. not shown.

[0227] It should be noted that, in the embodiments of the present application, the user operation can be a touch operation of the user (such as a click operation, a long press operation, a swipe up operation, a swipe down operation, or a side swipe operation), or a contactless operation (such as an air gesture), or a voice command of the user, and the embodiments of the present application do not impose specific restrictions on this. It should be noted that, in the embodiments of the present application, the user operation can be a touch operation of the user (such as a click operation, a long press operation, a swipe up operation, a swipe down operation, or a side swipe operation), or a contactless operation (such as an air gesture), or a voice command of the user, and the embodiments of the present application do not impose specific restrictions on this.

[0228] The calling method may include some or all of the following steps:

[0229] S101: A first call application of a first terminal receives a user operation instructing to call a second user through card 1.

[0230] The user operation may be one or more user operations.

[0231] For example, the first user can click on the application icon of the first call application on the first terminal. Accordingly, the first terminal can display the contact interface of the first call application in response to the user operation, and the contact interface includes the user name of the second user; further, the first terminal can display a pop-up window in response to the user operation acting on the user name of the above-mentioned second user, and the pop-up window includes the call control corresponding to card 1 and the call control corresponding to card 2; further, the first terminal can receive the call control corresponding to card 1, and execute the following step S102 in response to the user operation.

[0232] For another example, the first terminal can display a dialing interface, which includes number keys from 1 to 9 and a call control corresponding to card 1; then, the first terminal can display the mobile phone number of the second user in response to the user operation of entering the mobile phone number of the second user; then, the user can click on the call control, and accordingly, the first call application of the first terminal receives the user operation instructing to call the second user through card 1.

[0233] It should be noted that the embodiment of the present application is described by taking the first user using the first terminal to call the second user as an example, and the call between the first user and the second user is referred to as the first call. In other embodiments of the present application, the first call may also be the second user calling the first user, and the first user answering the call through the first terminal, and the present application does not limit this.

[0234] S102: The first call application sends a dial command to the first communication framework, where the dial command carries the mobile phone number of the second user.

[0235] In some embodiments, the first call application of the first terminal sends a dial command to the first communication framework in response to a user operation indicating to call the second user through card 1, and the dial command carries the mobile phone number of the second user.

[0236] Optionally, the dial command may also include information such as the identification of the card 1.

[0237] In one implementation, the first call application can also respond to a user operation indicating to call the second user through card 1 and display a calling interface, which includes user information of the calling party (i.e., the second user), such as the second user's mobile phone number or the second user's name.

[0238] S103: The first communication framework sends a dial command to the Modem.

[0239] In some embodiments, the rild process may convert the dial command issued by the first communication framework into an AT command recognizable by the modem and send it to the modem.

[0240] S104: The modem sends a first call request to the base station based on card 1.

[0241] The first call request is obtained based on the dial command, and the first call request may include the mobile phone number of the second user and information of the first terminal, such as the mobile phone number of the first user.

[0242] S105: When receiving the response message from the base station, the modem reports to the first communication framework that the first call is in an active state.

[0243] The above-mentioned response message may be a response message sent by the base station to the first terminal after receiving the first call request, and the response message is used to indicate that the base station has received the first call request.

[0244] S106: The first communication framework requests the first call application to display a first call interface.

[0245] Furthermore, when the first communication framework determines that the first call is in an active state, the first communication framework requests the first call application to display the first call interface.

[0246] S107: The first call application displays a first call interface, which includes user information of the second user.

[0247] Among them, the first call interface can be an interface in the first call; the user information of the second user can be the mobile phone number of the second user or the user name of the second user, etc.

[0248] For example, the first call interface can be found in Figure 5A 1 and 10. The user information of the second user may be shown in the call object information 511. The call object information 511 may include the call object name 511A, the call object address 511B and the SIM card identifier 511C, wherein the SIM card identifier 511C is used to indicate the information of the SIM card used for the first call. Figure 5A The example shows that the call object name 511A is Bob, and Bob can be the name note of the number on the first terminal; the example shows that the address 511B of the call object is Shenzhen, Guangdong, and the SIM card identifier 511C is card 1.

[0249] S108: When determining that the first call is active, the first communication framework requests the first audio framework to set the audio mode to the call mode.

[0250] For example, when the audio mode is call mode, the volume control key is used to control the playback volume of the call; when a call comes in again in call mode, the device can vibrate and emit a beep sound instead of the default ringtone to avoid the ringtone interfering with the ongoing call; when music is played during a call, the audio channel of the music can be consistent with the audio channel of the call, rather than the default external speaker to avoid the music interfering with the ongoing call.

[0251] S109: The first audio framework requests the HiFi module to play the audio of the first call through the receiver or speaker of the first terminal.

[0252] In some embodiments, the first audio framework requests the HiFi module to play the audio of the first call through the earpiece of the first terminal by default; when the user requests to play the audio of the first call through the speaker, the first audio framework can request the HiFi module to play the audio of the first call through the speaker of the first terminal.

[0253] It should be noted that S108 and S109 may be performed simultaneously or successively, and this is not limited in the embodiment of the present application.

[0254] S201: When the modem receives a second call request for card 2, it sends the second call request to the first communication framework, where the second call request includes user information of a third user.

[0255] The user information of the third user may include the mobile phone number of the third user and the SIM card information used by the third user, and the SIM card information may include the operator information of the SIM card.

[0256] S202: After receiving the second call request, the first communication framework sends user information of the third user to the first call application.

[0257] In one implementation, after receiving the second call request, the first communication framework may parse the second call request to obtain the user information of the third user, and then send the user information of the third user to the first call application. The user information of the third user may include the mobile phone number of the third user and the SIM card information used by the third user, and the SIM card information may include the operator information and location information of the SIM card.

[0258] Optionally, the first communication framework may also send the location of the third user's SIM card and the SIM card information of the third user making the call to the first call application.

[0259] S203: The first call application displays a first incoming call interface, where the first incoming call interface includes user information of the third user.

[0260] The first incoming call interface is used to display the call request of the third user. Figure 5B As shown in the user interface 52, the user information of the third user may be shown as the second incoming call information 521. Figure 5A The example shows that the name of the third user is "Jane", and Jane can be the name annotation of the second user on the first terminal; the example shows that the location of the SIM card of the third user is "Shenzhen, Guangdong", and the identification of the SIM card dialed by the third user is "Card 2".

[0261] In some other embodiments of the present application, when the third user has a contact name in the contacts of the first call application, the first incoming call interface can display the contact name of the third user, and the contact name can be obtained based on the user information of the third user. For example, the user information of the third user can be the mobile phone number of the third user, and the first call application can search for the contact name corresponding to the mobile phone number in the contact information based on the mobile phone number of the third user, and display the contact name on the first incoming call interface.

[0262] S204: After receiving the second call request, the first communication framework sends the second call request to the second terminal via Bluetooth.

[0263] In one implementation, when receiving the second call request, the first communication framework queries whether there are other calls in an active state; when it is found that the first call is active, the second call request is sent to the second terminal via Bluetooth.

[0264] The second terminal may be all electronic devices with which the first terminal establishes short-range communication, or may be an electronic device determined by the first terminal from electronic devices with which the first terminal establishes short-range communication. For example, the first terminal establishes communication connections with multiple electronic devices, and the first terminal may use the electronic device closest to it as the second terminal.

[0265] It should be noted that Figure 8 Exemplarily, the first terminal and the second terminal communicate via Bluetooth transmission as an example. In other embodiments of the present application, the first terminal and the second terminal may communicate via other short-range communication methods, such as WiFi connection.

[0266] S205: After receiving the second call request, the second communication framework of the second terminal sends the user information of the third user to the second call application.

[0267] S206: The second call application displays a second incoming call interface, where the second incoming call interface includes user information of the third user.

[0268] Exemplarily, the second incoming call interface may be shown as user interface 53, and the user information of the third user may be such as the name of the call object 531A and the location of the call object 531B.

[0269] S207: The second call application receives a user operation instructing to answer the call.

[0270] In some embodiments, upon receiving a user operation indicating an answer, the second calling device executes the following steps S208 and S209.

[0271] For example, the second incoming call interface is shown in the user interface 53, and the user operation indicating the answering of the call may be to touch Figure 5C User operation of the answer control 533 in .

[0272] S208: The second call application sends an answer command to the second communication framework in response to the user operation instructing to answer the call, where the answer command is used to instruct to answer the second call request.

[0273] S209: The second communication framework sends a listening command to the first terminal via Bluetooth.

[0274] S210: After receiving the answering command, the first communication framework sends an answering command to the Modem.

[0275] In some embodiments, the rild process may convert the answer command sent by the first communication framework into an AT command recognizable by the modem and send it to the modem.

[0276] S211: The modem sends a connection request to the base station based on card 2.

[0277] The connection request is obtained by answering the command, and the connection request is used to request to establish a second call connection.

[0278] S212: When the modem receives the response message from the base station, it reports to the first communication framework that the second call is in an active state.

[0279] S213: The first communication framework requests the first call application to display the second call interface.

[0280] In some embodiments, when the first communication framework determines that the second call is active, it requests the first call application to display a second call interface, where the second call interface includes call information of the second call. The call information of the second call may include user information of a third user and duration of the second call, etc.

[0281] S214: The first call application displays a second call interface, which includes user information of the second user and user information of the third user.

[0282] Optionally, the second call interface may include information about the first call and information about the second call. Figure 5E As shown in the user interface 55 shown, the user interface 55 includes first call information 550 and second call information 551. The user information of the second user can be the contact name "Bob" in the first call information 550 and the call object name 551B (i.e. "Jane") of the second call in the second call information 551.

[0283] S215: The first communication framework sends the device identification of the second terminal to the first audio framework.

[0284] The device identifier of the second terminal may be a MAC address of the second terminal.

[0285] It should be understood that the device identification may be related to the communication mode between the first terminal and the second terminal. For example, when the first terminal communicates with the second terminal via a WiFi connection, the device identification of the second terminal may be the IP address of the second terminal.

[0286] S216: The first audio framework requests the HiFi module to play the downlink audio of the second call through the second terminal.

[0287] S217: The HiFi module sends the downlink audio of the second call to the second terminal via Bluetooth.

[0288] In some embodiments, upon receiving a request from the first audio framework to play the audio of the second call through the second terminal, the HiFi module sends the downlink audio of the second call to the second terminal.

[0289] The downlink audio of the second call may be the audio data obtained after the downlink audio received by the Modem from the base station is processed by the HiFi module.

[0334] The user operation may be one or more user operations.

[0335] For example, the first user can click on the application icon of the first call application on the first terminal. Accordingly, the first terminal can display the contact interface of the first call application in response to the user operation, and the contact interface includes the user name of the second user; further, the first terminal can display a pop-up window in response to the user operation acting on the user name of the above-mentioned second user, and the pop-up window includes the call control corresponding to card 1 and the call control corresponding to card 2; further, the first terminal can receive the call control corresponding to card 1, and in response to the user operation, execute the following step S302.
