Description

Call state monitoring method, device, equipment, storage medium and program product

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method, an apparatus, a device, a storage medium, and a program product for monitoring a call state.

Background

With the rapid development of terminal technology, the multi-screen cooperation technology is widely applied. The multi-screen cooperation refers to that after a first device (such as a mobile phone) is connected with a second device (such as a tablet computer), a screen picture of the first device is displayed in an interface of the second device in a mirror image mode. In this case, the user may cause the first device to execute a corresponding function by operating the screen of the first device displayed in the interface of the second device.

Under the scene of multi-screen cooperation, if the first device carries out operator conversation, the second device can be switched to carry out the acquisition and the playing of conversation voice, and then the cooperation conversation can be carried out. Specifically, when the first device and the second device perform a cooperative call, a microphone of the second device collects a call voice of a local user and sends the call voice to the first device, and the first device sends the call voice to the far-end call device; the far-end communication equipment sends the communication voice of the far-end user to the first equipment, the first equipment sends the communication voice to the second equipment, and the communication voice is played through a loudspeaker of the second equipment.

If the cooperative call needs to be realized under the multi-screen cooperation between the first device and the second device, the first device needs to monitor the call state of a Subscriber Identity Module (SIM) card installed in the first device, so as to determine whether the first device starts to perform the operator call. However, in a multi-screen coordination scenario, if a plurality of SIM cards are installed in the first device, the monitoring of the call state of the SIM cards is probabilistically ineffective, which may affect the proceeding of the coordination call.

Disclosure of Invention

The application provides a call state monitoring method, a call state monitoring device, call state monitoring equipment, a storage medium and a program product, which can simply, quickly and accurately determine the call state of each SIM card in all the SIM cards. The technical scheme is as follows:

in a first aspect, a method for monitoring a call state is provided. In the method, if the first device and the second device perform multi-screen cooperation, the first device acquires the identifier of each SIM card in all the SIM cards installed in the first device. And then, the first device creates a listener corresponding to each SIM card according to the identifier of each SIM card in all the SIM cards, wherein the listener corresponding to each SIM card is used for monitoring the call state of the corresponding SIM card. And the first equipment starts a listener corresponding to each SIM card in all the SIM cards to monitor the call states of all the SIM cards respectively.

The multi-screen cooperation refers to displaying a screen picture of the first device on an interface of the second device. That is, after the first device and the second device perform multi-screen coordination, the screen image of the first device is displayed on the interface of the second device. In this case, the user may cause the first device to execute a corresponding function by operating the screen of the first device displayed in the interface of the second device.

The first device is a device capable of operator conversation. One or more SIM cards can be installed in the first device, and the first device can use any one of the one or more SIM cards to carry out operator calls. The one or more SIM cards installed by the first device have identification. For any one SIM card, the identity of the SIM card is used to uniquely identify the SIM card.

And the corresponding listener established according to the identifier of each SIM card is used for monitoring the call state of the corresponding SIM card. That is, for any one of all the SIM cards installed by the first device, the first device may create a listener corresponding to the SIM card according to the identifier of the SIM card, where the listener corresponding to the SIM card is used to monitor the call state of the SIM card.

The call state is used for indicating the conversion from idle to call or indicating the conversion from call to idle. For one SIM card, if the SIM card is idle, the SIM card is not used for the operator to talk; if the SIM card is in the call, the SIM card is used for the operator call. In this case, if the first device starts to perform the carrier call by using the SIM card, the call state of the SIM card changes from idle to active. Then, if the first device hangs up the operator call made by the SIM card, the call state of the SIM card is changed from call transfer to idle.

The listener is a monitoring interface and is used for receiving the call state change event of the SIM card, and accordingly, the call state of the SIM card can be determined. For example, when a call state of one SIM card changes, that is, when the call state of the SIM card changes from idle to call, or when the call state of the SIM card changes from call to idle, a call state change event is generated, and at this time, a listener corresponding to the SIM card can receive the call state change event of the SIM card, and according to the call state change event, it can determine whether the call state of the SIM card changes from idle to call, or changes from call to idle.

In the application, after the first device starts the corresponding listener of each SIM card in all the SIM cards, the call state of each SIM card can be monitored by the corresponding listener. In this case, no matter the first device is equipped with one SIM card or a plurality of SIM cards, the call state of each SIM card is monitored by its corresponding listener. Therefore, no matter which SIM card is used by the first device for carrying out the operator call, the first device can be monitored in time, and accordingly the first device can execute corresponding service processing. The service logic of the whole scheme is reasonable, the monitoring process is simple, convenient and accurate, and redundant processing and resource waste are avoided.

The first device may have one or more card slots, each for mounting a SIM card, that is, each card slot corresponding to the SIM card mounted thereon. After a SIM card is installed in a card slot of the first device, the first device can use the SIM card to make or receive a call, that is, can use the SIM card to perform a call with the carrier. In this case, the operation of the first device acquiring the identity of each of all the SIM cards installed in the first device may be: the first equipment acquires the identification of each card slot in all card slots used for installing the SIM card in the first equipment, and acquires the identification of the SIM card installed in each card slot according to the identification of each card slot in all the card slot identifications.

As an example, a listener may be registered by the call management object. The call management object is used for managing the call state of the SIM card. For example, the call management object may be a telephone service manager, which is a service class for managing call status and network information. In this case, the operation of the first device creating the listener corresponding to each SIM card according to the identifier of each SIM card in all the SIM cards may be: for each SIM card in all the SIM cards, the first device creates a call management object corresponding to the SIM card according to the identification of the SIM card, and then registers a listener as the listener corresponding to the SIM card through the call management object corresponding to the SIM card.

Because the call management object corresponding to the SIM card is created according to the identifier of the SIM card, the call management object corresponding to the SIM card is used for managing the call state of the SIM card. In this case, the listener registered by the call management object corresponding to the SIM card is also used to monitor the call state of the SIM card, that is, the listener registered by the call management object corresponding to the SIM card is also the listener corresponding to the SIM card.

In this case, if only one SIM card is installed in the first device, only the listener corresponding to the SIM card is registered, and an event notification is received in the corresponding listener when the call state of the SIM card is changed. If a plurality of SIM cards are installed in the first device, corresponding listeners are respectively registered for the plurality of SIM cards, and an event notification is received in the corresponding listener when the call state of each SIM card is changed.

As an example, in a multi-screen coordination scenario, the first device may default to automatically perform a coordination call when an operator call is performed, that is, default to automatically switch a call voice to the second device performing multi-screen coordination with the first device when the operator call is performed. Or, the user may manually start the cooperative call function in the first device, for example, the user may open a switch for switching a call voice to the second device from a notification bar of the first device or the second device to start the cooperative call function, so as to instruct the first device to automatically perform the cooperative call when performing the operator call.

In this case, for any one of all the SIM cards installed by the first device, the one SIM card may be referred to as a target SIM card. If the first device monitors that the call state of the target SIM card is converted from idle to call through the listener corresponding to the target SIM card, the first device starts operator call by using the target SIM card, and the first device can perform collaborative call in the process of using the target SIM card to perform operator call, so that the second device performing multi-screen collaboration with the first device performs acquisition and playing of operator call voice. And then, if the first device monitors that the call state of the target SIM card is idle from call transfer through the listener corresponding to the target SIM card, and the first device indicates that the operator call performed by the target SIM card is hung up, the first device may end the cooperative call to stop the collection and playing of the second device for the call voice of the operator. Therefore, the starting and the ending of the cooperative call can be flexibly and accurately realized.

The first device performs the collaborative call in the process of using the target SIM card to perform operator call, which means that the call voice of the operator call performed by the first device using the target SIM card is switched to the second device, and the second device performs the collection and playing of the call voice. Specifically, when the first device and the second device perform a cooperative call, a microphone of the second device collects a call voice of a local user and sends the call voice to the first device, and the first device sends the call voice to the far-end call device; the far-end communication equipment sends the communication voice of the far-end user to the first equipment, the first equipment sends the communication voice to the second equipment, and the communication voice is played through a loudspeaker of the second equipment.

Then, if the first device suspends the operator call by the target SIM card, which indicates that the first device does not have the requirement for the cooperative call, the first device may end the cooperative call. In this case, the operator collects and plays the conversation voice to restore the original state, i.e. switches back to the first device for execution.

In a second aspect, a call state monitoring apparatus is provided, where the call state monitoring apparatus has a function of implementing the behavior of the call state monitoring method in the first aspect. The call state monitoring device comprises at least one module, and the at least one module is used for realizing the call state monitoring method provided by the first aspect.

In a third aspect, a call state monitoring apparatus is provided, where the structure of the call state monitoring apparatus includes a processor and a memory, and the memory is used to store a program that supports the call state monitoring apparatus to execute the call state monitoring method provided in the first aspect, and store data used to implement the call state monitoring method in the first aspect. The processor is configured to execute programs stored in the memory. The talk state monitoring apparatus may further include a communication bus for establishing a connection between the processor and the memory.

In a fourth aspect, a computer-readable storage medium is provided, where instructions are stored in the computer-readable storage medium, and when the instructions are executed on a computer, the instructions cause the computer to execute the call state monitoring method according to the first aspect.

In a fifth aspect, a computer program product containing instructions is provided, which when run on a computer, causes the computer to execute the call state monitoring method of the first aspect.

The technical effects obtained by the second, third, fourth and fifth aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and are not described herein again.

Fig. 2 is a block diagram of a software system of the terminal 100 according to an embodiment of the present disclosure. Referring to fig. 2, the layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system layer, and a kernel layer from top to bottom.

For example, a notification manager is used to notify download completion, message alerts, and the like. The notification manager may also be a notification that appears in the form of a chart or scrollbar text at the top status bar of the system, such as a notification of a background running application. The notification manager may also be a notification that appears on the screen in the form of a dialog window, such as prompting a text message in a status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system. The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The surface manager is used to manage the display subsystem and provide a fusion of the 2D and 3D layers for multiple applications. The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The following describes application scenarios related to embodiments of the present application.

Under the condition that the mobile phone and the tablet computer are in multi-screen cooperation, if the mobile phone carries out operator conversation, the mobile phone can be switched to the tablet computer to carry out collection and playing of conversation voice, and then the cooperative conversation can be carried out. If the cooperative call needs to be realized under the condition that the mobile phone and the tablet computer perform multi-screen cooperation, the mobile phone needs to monitor the call state of the SIM card installed on the mobile phone to determine whether the mobile phone starts to perform operator call. When the mobile phone monitors that the conversation state of the SIM card is converted from idle to conversation, the mobile phone determines that the mobile phone starts to carry out conversation of an operator, and can be switched to a tablet personal computer to carry out collection and playing of conversation voice.

However, currently, when monitoring the call state, the default is to monitor the call state of the SIM card in the main card slot. Therefore, when the mobile phone is inserted into the dual card, the mobile phone cannot monitor the started operator call when the mobile phone uses the SIM card in the sub card slot to perform the operator call, and cannot switch to the tablet computer to perform the collection and the playing of the call voice. In this case, when the mobile phone uses the SIM card in the sub-card slot to perform a call of the operator, the expected call voice is on the tablet computer side, but the actual call voice is still on the mobile phone side, and the cooperative call fails.

Therefore, the embodiment of the application provides a call state monitoring method, which can simply, quickly, accurately and efficiently monitor the call states of all the SIM cards installed in a mobile phone while the mobile phone and a tablet computer perform multi-screen coordination.

In the following, taking the multi-screen coordination of the mobile phone and the tablet pc as an example, several possible connection manners of the multi-screen coordination are described.

1. The connection is established via bluetooth.

For example, if the user wants to cooperate the mobile phone with the tablet computer, the bluetooth of both the mobile phone and the tablet computer may be turned on first. Then, the user manually starts the multi-screen cooperative function in the mobile phone. For example, a user may find a multi-screen cooperation switch in an interface of a mobile phone through a path of "set" - "more connect" - "multi-screen cooperation", and set the switch to an on state, so as to start a multi-screen cooperation function of the mobile phone.

Referring to the interface diagram of the tablet computer shown in fig. 3, as shown in fig. 3 (a), the user slides down a notification panel from the status bar of the tablet computer, and the notification panel includes a "multi-screen collaboration" option 31. The user clicks the "multi-screen collaboration" option 31, the tablet computer responds to a trigger operation of the user on the "multi-screen collaboration" option 31, and displays a first prompt window, where the first prompt window includes first operation prompt information for instructing the user how to operate to implement multi-screen collaboration. For example, as shown in fig. 3 (b), the first operation prompt message includes "1. turn on your mobile phone bluetooth and approach to the local machine, and click" connect "after finding the local machine.

2. After connection, the mobile phone can be operated on the tablet personal computer, and data sharing among the devices is achieved. "is used as the prompt. Therefore, the user can perform corresponding operation according to the first operation prompt message, for example, the mobile phone is close to the tablet personal computer.

In one example, referring to the interface schematic diagram of the mobile phone shown in fig. 4, when the mobile phone finds a tablet computer during the process that the mobile phone approaches the tablet computer, the mobile phone displays a second prompt window, as shown in fig. 4 (a), where the second prompt window includes a prompt content of "whether to establish a collaborative connection with the found device", and a "connection" option 41 and a "cancellation" option 42. When the user clicks the connection option 41, it indicates that the user confirms that the cooperative connection is to be established, and the mobile phone responds to the triggering operation of the user on the connection option 41 and establishes the cooperative connection with the tablet computer through the bluetooth. When the user clicks the cancel option 42, it indicates that the user does not want to establish the cooperative connection, and the mobile phone does not execute the operation of establishing the cooperative connection in response to the triggering operation of the user on the cancel option 42. In another example, during the process that the mobile phone approaches the tablet computer, when the mobile phone finds the tablet computer, the second prompt window may not be displayed, and the cooperative connection with the tablet computer is automatically established through bluetooth.

By way of example and not limitation, in the process of establishing the cooperative connection between the mobile phone and the tablet computer through bluetooth, in order to display the progress of establishing the cooperative connection, the mobile phone may further display a third prompt window for indicating that the connection is being made, for example, the third prompt window shown in (b) in fig. 4 may be displayed. Optionally, a "cancel" option is included in the third prompt window to facilitate the user to cancel the connection at any time if desired.

2. And establishing connection in a code scanning mode.

For example, the user may find a button of "scan connection" in the interface of the tablet computer through a "my mobile phone" - "immediate connection" - "scan connection" path, the user clicks the button, and the tablet computer displays a two-dimensional code for establishing a cooperative connection in response to a trigger operation of the user on the button, for example, the two-dimensional code shown in fig. 5 may be displayed. Optionally, the tablet pc may further display a second operation prompt message for prompting the user how to operate to implement multi-screen coordination, for example, as shown in fig. 5, the second operation prompt message may be "scan code connection using a mobile browser".

In one example, referring to the interface schematic diagram of the mobile phone shown in fig. 6, the user may enter an interface with a "scan" option displayed in a browser (or smart vision) of the mobile phone, for example, may enter an interface of the browser shown in fig. 6 (a), where a "scan" option 61 is displayed. The user can click the "scan" option 61, and the mobile phone starts the camera in response to the triggering operation of the user on the "scan" option 61, and displays the code scanning interface shown in (b) in fig. 6, so that the user can align the camera with the two-dimensional code displayed by the tablet computer to perform code scanning operation.

In one example, after the mobile phone successfully scans the code, a request for establishing the cooperative connection is sent to the tablet computer. After receiving the request sent by the mobile phone, the tablet pc may display a fourth prompt window, where the fourth prompt window includes prompt information for prompting the user whether to agree to establish the cooperative connection, for example, the prompt information may include "xx device requests to establish the cooperative connection with the home terminal, and whether to agree to establish the cooperative connection? "and" agree "and" deny "options. When the user clicks the 'consent' option, the user is indicated that the mobile phone is allowed to establish the cooperative connection with the tablet computer, and the tablet computer responds to the trigger operation of the user on the 'consent' option and establishes the cooperative connection with the mobile phone. When the user clicks the 'reject' option, the user is indicated that the mobile phone is not allowed to establish the cooperative connection with the tablet computer, and the tablet computer responds to the trigger operation of the user on the 'reject' option and informs the mobile phone that the cooperative connection establishment fails.

It should be noted that, the above description is only given by taking an example that the user opens the two-dimensional code in the tablet computer through a path from "my mobile phone" - "immediate connection" - "scan code connection". Alternatively, the two-dimensional code may be opened through other paths. For example, as shown in fig. 3 (b), the first prompt window includes, in addition to the first operation prompt information, "cannot find a local device? You can also scan the prompt content of the code connection, wherein four words of the code connection are triggerable. The user can click the content of the code scanning connection in the first prompt window, and the tablet computer responds to the triggering operation of the user on the content of the code scanning connection and displays the two-dimensional code shown in fig. 5. Therefore, the user can scan the two-dimensional code displayed by the tablet personal computer through the mobile phone, and the cooperative connection is established in a code scanning mode.

3. The connection is established by means of a bump-on-bump.

The user can start the NFC and multi-screen cooperative function in both the mobile phone and the tablet computer. Then, the user touches the NFC region on the back of the mobile phone (usually located around the camera on the back of the mobile phone) to the NFC region on the tablet computer (usually located in the lower right corner region of the tablet computer), and the mobile phone and the tablet computer respond to the touch operation of the user and establish the cooperative connection through NFC. Optionally, before the cooperative connection is established through NFC, the tablet computer and the mobile phone may further prompt the user whether to agree to establish the cooperative connection, and after the user agrees to establish the cooperative connection, the mobile phone and the tablet computer perform an operation of establishing the cooperative connection. In one example, when the mobile phone and the tablet computer successfully establish the cooperative connection, the mobile phone may further remind the user by vibrating or ringing.

It should be noted that, the above several possible connection manners are all described by taking a wireless connection manner as an example. In another embodiment, the implementation may also be implemented by a wired connection manner, for example, the implementation may be implemented by a connection line of a Type-C to high-definition multimedia interface (HDMI), which is not limited in this embodiment of the present application.

After the mobile phone and the tablet computer successfully establish the cooperative connection, as shown in fig. 7, the tablet computer displays the screen picture of the mobile phone in a mirror image manner. Therefore, the user can operate the screen picture of the mobile phone displayed by the tablet personal computer in the tablet personal computer according to the requirement, so that the mobile phone executes the corresponding function. In an example, the mobile phone and the tablet computer synchronously display the main interface of the mobile phone as shown in fig. 7, and if the user wants to make a call, an icon of the call can be clicked in the main interface of the mobile phone displayed by the tablet computer to open the dialing interface of the mobile phone, and at this time, the mobile phone and the tablet computer synchronously display the dialing interface of the mobile phone. Then, the user can carry out dialing operation in a dialing interface of the mobile phone displayed by the tablet personal computer so as to realize dialing in the mobile phone.

After a call is made in the mobile phone, if the mobile phone starts to perform operator call, as shown in fig. 8, the mobile phone and the tablet computer can synchronously display the call interface of the mobile phone. When the mobile phone carries out operator communication, the mobile phone can be selectively switched to the tablet personal computer to carry out acquisition and playing of communication voice, and then collaborative communication can be carried out. Specifically, when the mobile phone and the tablet personal computer perform cooperative communication, a microphone of the tablet personal computer collects communication voice of a local user and sends the communication voice to the mobile phone, and the mobile phone sends the communication voice to the far-end communication equipment; the remote communication equipment sends the communication voice of the remote user to the mobile phone, and the mobile phone sends the communication voice to the tablet personal computer and the communication voice is played through a loudspeaker of the tablet personal computer.

For example, after the mobile phone and the tablet computer perform multi-screen coordination, if the mobile phone starts to perform operator call, as shown in fig. 8, after the user pulls down the notification bar of the tablet computer in the tablet computer, the notification bar of the tablet computer may display a prompt content of "coordination to mobile phone", the notification bar may further include a switch for switching call voice to the tablet computer, and the user may operate the switch as required to indicate whether to switch the call voice to the tablet computer, i.e., whether to perform coordination call. Or, the user may pull down the notification bar of the mobile phone in the mobile phone, the notification bar of the mobile phone may display the prompt content of "the cooperative call to the tablet computer", the notification bar may further include a switch for switching the call voice to the tablet computer, and the user may operate the switch according to the requirement to indicate whether the cooperative call is performed. If the user instructs to switch the call voice to the tablet computer by operating the switch for switching the call voice to the tablet computer on the tablet computer or the mobile phone in the process of the operator call of the mobile phone, that is, instructs to perform the cooperative call, the collection and the playing of the call voice of the operator call which is currently performed by the mobile phone are executed on the tablet computer side. If the user instructs not to switch the call voice to the tablet pc, that is, instructs not to perform the cooperative call, by operating the switch for switching the call voice to the tablet pc on the tablet pc or the mobile phone during the call of the operator by the mobile phone, the collection and the playing of the call voice of the operator call being performed by the mobile phone are still performed on the mobile phone side.

It is to be noted that, in some embodiments, in a multi-screen collaborative scenario, the mobile phone may also default to automatically perform a collaborative call when performing an operator call. That is, after the mobile phone and the tablet computer perform multi-screen coordination, if the mobile phone starts to perform operator conversation, user operation is not required, and the coordinated conversation can be automatically performed, that is, the collection and the playing of the conversation voice are automatically switched to the tablet computer side for execution. In this case, if the user does not want to perform the cooperative call, the user may instruct, by operating the switch for switching the call voice to the tablet pc, to not switch the call voice to the tablet pc, that is, instruct to close the cooperative call, and switch the call voice back to the mobile phone, where the collection and playback of the call voice of the operator call being performed by the mobile phone are switched back to the mobile phone side to be continuously executed.

As can be seen from the above description, if it is necessary to implement cooperative call under the multi-screen cooperation between the mobile phone and the tablet computer, the mobile phone is required to monitor the call state of the SIM card installed in the mobile phone, so as to determine whether the mobile phone starts to perform operator call. When the mobile phone monitors that the conversation state of the SIM card is converted from idle to conversation, the mobile phone can determine that the mobile phone starts to carry out conversation of an operator, and can switch to a tablet personal computer to carry out collection and playing of conversation voice, namely, carry out cooperative conversation. Therefore, the embodiment of the application provides a call state monitoring method, which can monitor the call states of all the SIM cards installed in a mobile phone simply, quickly and accurately while the mobile phone and a tablet computer perform multi-screen coordination.

The call state monitoring method provided by the embodiment of the application is applied to a multi-screen coordination system, and the multi-screen coordination system is explained below.

Fig. 9 is a schematic diagram of a multi-screen collaborative system according to an embodiment of the present application. Referring to fig. 9, the multi-screen collaborative system may include a first device 901 and a second device 902. The first device 901 and the second device 902 may communicate through a wired connection or a wireless connection.

Both the first device 901 and the second device 902 may be terminals, which may be terminals as described above in the embodiments of fig. 1-2. For example, the terminal may be a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a television, and the like, which is not limited in the embodiments of the present application.

The first device 901 and the second device 902 can perform multi-screen cooperation. After the first device 901 and the second device 902 perform multi-screen coordination, a screen of the first device 901 may be displayed on an interface of the second device 902.

The first device 901 and the second device 902 may be different types of terminals, and may also be the same type of terminals, which is not limited in this embodiment of the application. For example, both of them may be terminals such as a mobile phone or a tablet computer.

In a possible implementation manner, the screen size of the first device 901 is smaller than the screen size of the second device 902, so that when the small screen and the large screen perform multi-screen coordination, the screen picture of the small screen is displayed to the interface of the large screen as a window, which can be used by a user to operate the screen picture of the small screen in the interface of the large screen, and improve the operation experience of the user. For example, the first device 901 is a mobile phone, and the second device 902 is a tablet computer or a television. Alternatively, the first device 901 is a tablet computer, and the second device 902 is a television. Of course, the screen size of the first device 901 may be larger than the screen size of the second device 902. For example, the first device 901 is a tablet computer, and the second device 902 is a mobile phone.

Under the condition that the first device 901 and the second device 902 perform multi-screen coordination, the first device 901 needs to monitor the call state of the SIM card installed in the first device 901 to determine whether to start an operator call, so as to determine whether to switch to the second device 902 to collect and play call voice, i.e., determine whether to perform coordination call. The call state monitoring method provided by the embodiment of the present application is applied to a scene where the first device 901 and the second device 902 perform multi-screen coordination. In this case, the first device 901 can perform multi-screen coordination with the second device 902 and simultaneously, simply, quickly and accurately monitor the call states of all the SIM cards installed in the first device 901 by executing the call state monitoring method provided in the embodiment of the present application.

The following explains the call state monitoring method provided in the embodiment of the present application in detail.

Fig. 10 is a flowchart of a call state monitoring method according to an embodiment of the present application, where the method is applied to a first device, and the first device and a second device can perform multi-screen coordination, where the multi-screen coordination is to display a screen of the first device on an interface of the second device. Referring to fig. 10, the method includes:

step 1001: if the first device and the second device perform multi-screen cooperation, the first device acquires the identifier of each SIM card in all the SIMs installed in the first device.

After the first device and the second device perform multi-screen cooperation, a screen picture of the first device is displayed on an interface of the second device. In this case, the user may cause the first device to execute a corresponding function by operating the screen of the first device displayed in the interface of the second device. The first device and the second device may implement multi-screen coordination in multiple possible manners, for example, the multi-screen coordination may be implemented in manners such as bluetooth, code scanning, and touching one touch, which are described in detail above, and are not described again in this embodiment of the present application.

The first device is a device capable of operator conversation. One or more SIM cards can be installed in the first device, and the first device can use any one of the one or more SIM cards to carry out operator calls. For example, in the case that the first device has only one SIM card installed, the first device may directly use the SIM card to perform a carrier call, for example, the first device may use the SIM card to make a call or use the SIM card to listen to a call. In the case that the first device has multiple SIM cards, the first device may use one of the multiple SIM cards to perform an operator call, for example, may use the SIM card to make a call or use the SIM card to listen to a call.

In the case that the first device and the second device perform multi-screen coordination, the user may directly operate in the first device to cause the first device to start to perform operator conversation, or may operate in the second device to cause the first device to start to perform operator conversation.

Several possible operating modes will be described below, taking as an example the initiation of a carrier call by dialing a telephone number in the first device.

In a first possible operation mode, if the user wants to make a call in the first device, the operation can be performed directly on the first device.

For example, the user may click an icon of a dialing phone in the main interface of the first device to open the dialing interface of the first device, and then the user may perform a dialing operation in the dialing interface of the first device to dial a phone in the first device to start a carrier call. Under the condition that the first equipment is only provided with one SIM card, a user can directly carry out dialing operation in a dialing interface of the first equipment, so that the SIM card is used for making a call in the first equipment; in the case that the first device is provided with a plurality of SIM cards, the user may select one SIM card in the dialing interface of the first device, and then perform dialing operation on the dialing interface of the first device, so that the selected SIM card is used in the first device to make a call.

In a second possible operation manner, if a user wants to make a call in a first device, the operation may be performed in a second device that performs multi-screen coordination with the first device.

For example, after the first device and the second device perform multi-screen coordination, the first device and the second device synchronously display a main interface of the first device, a user can click an icon for making a call in the main interface of the first device displayed by the second device to open a dialing interface of the first device, at this time, the first device and the second device can synchronously display the dialing interface of the first device, and then the user can perform dialing operation in the dialing interface of the first device displayed by the second device to dial a call in the first device to start an operator call. Under the condition that the first equipment is only provided with one SIM card, a user can directly carry out dialing operation in a dialing interface of the first equipment displayed by the second equipment, so that the SIM card can be used in the first equipment to make a call; under the condition that the first equipment is provided with a plurality of SIM cards, a user can select one SIM card in the dialing interface of the first equipment displayed by the second equipment, and then the dialing operation is carried out on the dialing interface of the first equipment displayed by the second equipment, so that the user can use the selected SIM card to make a call in the first equipment.

In a third possible operation manner, if a user wants to make a call in the first device, the operation may be performed in both the first device and the second device performing multi-screen coordination with the first device.

For example, after the first device and the second device perform multi-screen coordination, the first device and the second device synchronously display a main interface of the first device, a user may click an icon for making a call in the main interface of the first device displayed by the second device to open a dialing interface of the first device, at this time, the first device and the second device may synchronously display the dialing interface of the first device, and then the user may perform a dialing operation in the dialing interface of the first device to make a call in the first device to start an operator call. Under the condition that the first equipment is only provided with one SIM card, a user can directly carry out dialing operation in a dialing interface of the first equipment, so that the SIM card is used for making a call in the first equipment; in the case that the first device is provided with a plurality of SIM cards, the user may select one SIM card in the dialing interface of the first device, and then perform dialing operation on the dialing interface of the first device, so that the selected SIM card is used in the first device to make a call.

For another example, after the first device and the second device perform multi-screen coordination, the first device and the second device synchronously display a main interface of the first device, the user may click an icon for making a call in the main interface of the first device to open a dialing interface of the first device, at this time, the first device and the second device synchronously display the dialing interface of the first device, and then the user may perform a dialing operation in the dialing interface of the first device displayed by the second device to dial a call in the first device to start an operator call. Under the condition that the first equipment is only provided with one SIM card, a user can directly carry out dialing operation in a dialing interface of the first equipment displayed by the second equipment, so that the SIM card can be used in the first equipment to make a call; under the condition that the first equipment is provided with a plurality of SIM cards, a user can select one SIM card in the dialing interface of the first equipment displayed by the second equipment, and then the dialing operation is carried out on the dialing interface of the first equipment displayed by the second equipment, so that the user can use the selected SIM card to make a call in the first equipment.

Several possible operating modes will be described below, taking as an example the answering of a dialed call in the first device to start a carrier call.

In a first possible operation manner, when there is a phone call dialed in the first device, if the user wants to answer the phone call dialed in the first device, the operation may be performed on the first device.

For example, if there is a phone call dialed in the first device, the first device may display a call interface, and the user may click an answer button in the call interface of the first device, so as to answer the phone call dialed in the first device to start the operator call. Wherein, under the condition that the first equipment is only provided with one SIM card, the telephone dialed in the first equipment is the telephone dialed in the SIM card, so that the SIM card is used in the first equipment to answer the telephone; in the case where the first device has a plurality of SIM cards installed therein, the telephone dialed in the first device is a telephone that dials in one of the plurality of SIM cards, and thus the one SIM card is used in the first device to receive a call.

In a second possible operation manner, when there is a phone call dialed in the first device, if the user wants to answer the phone call dialed in the first device, the operation may be performed on the second device that performs multi-screen coordination with the first device.

For example, after the first device and the second device perform multi-screen coordination, if there is a call dialed in by the first device, the first device and the second device may synchronously display an incoming call interface of the first device, and the user may click an answer button in the incoming call interface of the first device displayed by the second device, so as to answer the call dialed in by the first device to start an operator call. Wherein, under the condition that the first equipment is only provided with one SIM card, the telephone dialed in the first equipment is the telephone dialed in the SIM card, so that the SIM card is used in the first equipment to answer the telephone; in the case where the first device has a plurality of SIM cards installed therein, the telephone dialed in the first device is a telephone that dials in one of the plurality of SIM cards, and thus the one SIM card is used in the first device to receive a call.

The SIM card or cards installed by the first device have an identification (which may be referred to as a subID). For any one SIM card, the identity of the SIM card is used to uniquely identify the SIM card.

The first device may have one or more card slots, each for mounting a SIM card, that is, each card slot corresponding to the SIM card mounted thereon. After a SIM card is installed in a card slot of the first device, the first device can use the SIM card to make or receive calls, i.e., can use the SIM card to conduct carrier calls.

In this case, the operation of the first device acquiring the identity of each of all the SIM cards installed by the first device may be: the first equipment acquires the identification of each card slot in all card slots used for installing SIM cards in the first equipment, and then acquires the identification of the SIM card installed in each card slot according to the identification of each card slot in all the card slot identifications.

One or more card slots in the first device have an identification. For any card slot, the identification of the card slot is used for uniquely identifying the card slot. The first device stores in advance an identification of each of all the card slots.

As an example, the first device may store a correspondence between the card slot identifier and the SIM card identifier, where the correspondence includes an identifier of each card slot in all card slots in the first device. For any card slot of all card slots in the first device, if a SIM card is inserted into the card slot, the first device may store the identifier of the SIM card in the corresponding relationship as the SIM card identifier corresponding to the identifier of the card slot. If the SIM card is pulled out from the card slot, the first device may delete the SIM card identifier corresponding to the identifier of the card slot in the correspondence relationship, and at this time, the identifier of the card slot does not have a corresponding SIM card identifier in the correspondence relationship.

For example, the correspondence between the card slot identifier and the SIM card identifier may be as shown in table 1 below. In the correspondence shown in table 1, the card slot identifier 1 corresponds to the SIM card identifier 1, and the card slot identifier 2 does not have a corresponding SIM card identifier. According to the corresponding relationship shown in table 1, the card slot identified by the card slot identifier 1 is installed with the SIM card identified by the SIM card identifier 1, and the card slot identified by the card slot identifier 2 is not currently installed with the SIM card.

TABLE 1

Card slot identification	SIM card identification
		Card slot identification 1	SIM card identification 1
Card slot identification 2

In the embodiment of the present application, the correspondence between the card slot identifier and the SIM card identifier is described only by taking table 1 as an example, and table 1 does not limit the embodiment of the present application.

In this case, the operation of the first device obtaining the identifier of the SIM card installed in each card slot according to the identifier of each card slot in the identifiers of all the card slots may be: for the identifier of each card slot in all card slots in the first device, the first device may obtain, according to the identifier of the card slot, a corresponding SIM card identifier from the correspondence between the card slot identifier and the SIM card identifier, where the obtained SIM card identifier is the identifier of the SIM card installed in the card slot. If the first device does not obtain the corresponding SIM card identifier from the corresponding relationship between the card slot identifier and the SIM card identifier according to the identifier of the card slot, it indicates that the SIM card is not installed in the card slot currently.

For example, the first device has two card slots, one card slot being identified as slot identification 1 and the other card slot being identified as slot identification 2. The first device acquires that the corresponding SIM card identifier is the SIM card identifier 1 from the correspondence between the card slot identifier and the SIM card identifier shown in table 1 above according to the card slot identifier 1, and the acquired SIM card identifier 1 is the identifier of the SIM card installed in the card slot identified by the card slot identifier 1. And according to the card slot identifier 2, if the corresponding SIM identifier is not obtained from the correspondence between the card slot identifier and the SIM card identifier shown in table 1, the second device may determine that the SIM card is not currently installed in the card slot identified by the card slot identifier 2. Thus, the first device obtains that the identifiers of all the SIM cards installed by the first device (i.e., the SIM cards installed in the card slot identified by the card slot identifier 1) are the SIM card identifier 1.

As an example, the identity of the SIM card installed in any one card slot may be generated based on the number of SIM cards installed in that card slot. For example, after a SIM card is inserted into a card slot, if the SIM card is the i-th SIM card installed in the card slot, that is, before the SIM card is installed in the card slot, i-1 SIM card is installed in the card slot, the first device may set the identifier of the SIM card to i. Wherein i is a positive integer.

That is, the identification of the SIM card installed in this card slot is incremented. For example, for the first SIM card inserted into this card slot, the identity of the first SIM card may be 1. If another SIM card is continuously inserted into the card slot after the first SIM card is pulled out, the currently inserted SIM card is the second SIM card inserted into the card slot, and the identifier of the second SIM card may be 2. If a SIM card is continuously inserted into the card slot after the second SIM card is pulled out, the currently inserted SIM card is a third SIM card inserted into the card slot, and the identifier of the third SIM card may be 3.

Step 1002: and the first equipment creates a listener corresponding to each SIM card according to the identifier of each SIM card in all the SIM cards.

And the listener corresponding to each SIM card is used for monitoring the call state of the corresponding SIM card. That is, for any one of all the SIM cards installed by the first device, the first device may create a listener corresponding to the SIM card according to the identifier of the SIM card, where the listener corresponding to the SIM card is used to monitor the call state of the SIM card.

The call status is used to indicate a transition from idle to on-call (offhook), or vice versa. For one SIM card, if the SIM card is idle, the SIM card is not used for the operator to talk; if the SIM card is in the call, the SIM card is used for the operator call. In this case, if the first device starts a carrier call using the SIM card, the call state of the SIM card is changed from idle to active. Then, if the first device hangs up the operator call made by the SIM card, the call state of the SIM card is changed from call transfer to idle.

The listener (also called listener object) is a listening interface for receiving the call state change event of the SIM card, from which the call state of the SIM card can be determined. For example, when a call state of one SIM card changes, that is, when the call state of the SIM card changes from idle to call, or when the call state of the SIM card changes from call to idle, a call state change event is generated, and at this time, a listener corresponding to the SIM card can receive the call state change event of the SIM card, and according to the call state change event, it can determine whether the call state of the SIM card changes from idle to call, or changes from call to idle.

As an example, a listener may be registered by the call management object. The call management object is used for managing the call state of the SIM card. For example, the call management object may be a telephone service manager (TelephonyManager), which is a service class for managing call status and network information.

In this case, the operation of the first device creating the listener corresponding to each SIM card according to the identifier of each SIM card in all the SIM cards may be: for each SIM card in all the SIM cards installed by the first equipment, the first equipment creates a call management object corresponding to the SIM card according to the identification of the SIM card. And then, the first device registers a listener as the listener corresponding to the SIM card through the call management object corresponding to the SIM card.

Step 1003: and the first equipment starts a listener corresponding to each SIM card in all the SIM cards to monitor the call states of all the SIM cards respectively.

After the first device starts the corresponding listener of each SIM card in all the SIM cards, the call state of each SIM card can be monitored by the corresponding listener. In this case, no matter the first device is equipped with one SIM card or a plurality of SIM cards, the call state of each SIM card is monitored by its corresponding listener. Therefore, no matter which SIM card is used by the first device for carrying out the operator call, the first device can be monitored in time, and accordingly the first device can execute corresponding service processing.

As an example, in a multi-screen coordination scenario, the first device may default to automatically perform a coordination call when an operator call is performed, that is, default to automatically switch a call voice to the second device performing multi-screen coordination with the first device when the operator call is performed. Or, the user may manually turn on the cooperative call function in the first device, for example, the user may turn on a switch for switching a call voice to the second device from a notification bar of the first device or the second device to turn on the cooperative call function, so as to instruct the first device to automatically perform the cooperative call when performing the carrier call.

In this case, for any one of all the SIM cards installed by the first device, the one SIM card may be referred to as a target SIM card. If the first device monitors that the call state of the target SIM card is converted from idle to call through the listener corresponding to the target SIM card, the first device starts operator call by using the target SIM card, and the first device can perform collaborative call in the process of using the target SIM card to perform operator call, so that the second device performing multi-screen collaboration with the first device performs acquisition and playing of operator call voice. And then, if the first device monitors that the call state of the target SIM card is changed from call transfer to idle through the listener corresponding to the target SIM card, and the first device indicates that the operator call performed by the target SIM card is suspended, the first device can end the collaborative call so as to stop the acquisition and playing of the second device to the call voice of the operator.

Then, if the first device suspends the operator call by the target SIM card, which indicates that the first device does not have the requirement for the cooperative call, the first device may end the cooperative call. In this case, the operator collects and plays the call voice to restore the original state, i.e. switches back to the first device for execution.

For convenience of understanding, the above call state monitoring method is exemplified below with reference to fig. 11 and 12 by taking the first device as a mobile phone and the second device as a tablet computer.

The current mobile phone is generally in a dual-card dual-standby mode, namely, the mobile phone is provided with two card slots and can be provided with two SIM cards. However, the conventional call state monitoring method is for a single-card mobile phone, that is, the conventional call state monitoring method can only monitor the call state of one SIM card. Therefore, when the traditional call state monitoring mode is applied to the mobile phone with double cards, the call state of the SIM card in the main card slot is monitored by default, and the call state of the SIM card in the auxiliary card slot cannot be monitored. In order to solve this problem, the related art adjusts the conventional call state monitoring method. The following describes a call state monitoring method in the related art with reference to fig. 11.

Fig. 11 is a schematic diagram of a call state monitoring method provided in the related art. Referring to fig. 11, the call state listening mode may include the following steps a 1-a 6.

Step A1: the mobile phone and the tablet computer perform multi-screen cooperation.

Step A2: the mobile phone registers and starts a listener, and the listener defaults to monitor the call state of the SIM card in the main card slot of the mobile phone.

Step A3: if the mobile phone monitors that the call state (namely the call state of the SIM card in the main card slot) is converted from idle to call through the monitor, the mobile phone performs cooperative call to switch the call voice to the tablet personal computer.

Step A4: if the handset monitors that the call state is changed from call transfer to idle through the listener, step a5 is executed.

Step A5: the call states of the SIM cards in each card slot of all card slots (namely a main card slot and an auxiliary card slot) in the mobile phone are obtained in a traversing mode, namely the call states of all the SIM cards in the mobile phone are obtained.

Step A6: and judging whether the SIM card exists in the mobile phone or not in the process of communication. If all the SIM cards in the mobile phone are idle, ending the cooperative call; if the SIM card is in the call, the cooperative call is continuously kept.

That is to say, in the conventional call state monitoring manner, if the handset monitors that the call state is changed from call transfer to idle through the monitor, the handset directly ends the cooperative call. Therefore, the cooperative call can be realized only when the mobile phone uses the SIM card in the main card slot to carry out the operator call, so that the call voice is switched to the tablet personal computer. When the mobile phone uses the SIM card in the secondary card slot to perform the operator call, the cooperative call cannot be realized, that is, the call voice fails to be switched.

The related technology adjusts a traditional call state monitoring mode, specifically, when the mobile phone monitors that the call state is idle from call transfer through a monitor, the call state of the SIM card in each card slot in all card slots in the mobile phone is obtained through traversal, and if any SIM card is in the call, the collaborative call is continuously kept. Therefore, the mobile phone can successfully realize the cooperative communication no matter the mobile phone uses the SIM card in the main card slot or the auxiliary card slot to carry out the communication of the operator.

However, the call state monitoring method in the related art has the following problems: 1. unreasonable business logic: the method is designed for avoiding the problems in the traditional call state monitoring mode, and is only designed for rapidly solving the problems, so that the service logic is unreasonable. 2. Resource waste: no matter a plurality of SIM cards exist in the mobile phone, the call state of the SIM cards in each card slot in all card slots in the mobile phone needs to be traversed again as long as the call state is monitored to be idle from call transfer, and redundant processing and resource waste exist.

Therefore, aiming at the problems in the double-card scene and unreasonable related technical schemes, the embodiment of the application combs the service flow of call voice switching again and provides an optimization scheme. The following describes a call state monitoring method provided in the embodiment of the present application with reference to fig. 12.

Fig. 12 is a schematic diagram of a call state monitoring method according to an embodiment of the present application. Referring to fig. 12, the call state listening method may include the following steps B1-B5.

Step B1: the mobile phone and the tablet computer perform multi-screen cooperation.

The mobile phone and the tablet computer may implement multi-screen coordination in multiple possible manners, for example, the multi-screen coordination may be implemented in manners such as bluetooth, code scanning, and touch-and-touch, which are described in detail above, and are not described herein again in this embodiment of the present application.

Step B2: the mobile phone traverses and acquires the identification of the SIM card in each card slot of all card slots (namely a main card slot and a secondary card slot) in the mobile phone.

The operation of the mobile phone to traverse to obtain the identifier of the SIM card in each of all the card slots in the mobile phone is the same as the operation of the first device to obtain the identifier of the SIM card in each of all the card slots in the first device in step 1001, which is not described in detail herein.

Step B3: and the mobile phone registers and starts a corresponding listener for each SIM card according to the identifier of each SIM card, wherein the listener corresponding to each SIM card is used for monitoring the call state of the corresponding SIM card.

The operation of the mobile phone to register the corresponding listener for each SIM card according to the identifier of each SIM card is the same as the operation of the first device creating the corresponding listener for each SIM card according to the identifier of each SIM card in all SIM cards in step 1002, which is not described in detail herein in this embodiment.

The operation of the mobile phone starting the listener corresponding to each SIM card registration is the same as the operation of the first device starting the listener corresponding to each SIM card in all the SIM cards in step 1003, which is not described in detail herein for this embodiment of the present application.

That is to say, under the condition that the mobile phone has the main card slot and the auxiliary card slot, the mobile phone registers a corresponding listener for the SIM card in the main card slot according to the identifier of the SIM card in the main card slot, and the listener corresponding to the SIM card in the main card slot is used for monitoring the call state of the SIM card in the main card slot. And the mobile phone registers a corresponding listener for the SIM card in the auxiliary card slot according to the identifier of the SIM card in the auxiliary card slot, and the listener corresponding to the SIM card in the auxiliary card slot is used for monitoring the call state of the SIM card in the auxiliary card slot.

Step B4: if the mobile phone monitors that the call state is converted from idle to call through any one monitor, the mobile phone performs cooperative call to switch the call voice to the tablet personal computer.

When the mobile phone uses any one SIM card to start the operator call (for example, when the SIM card is used to make a call or receive an incoming call), the call state of the SIM card changes from idle to in-call, and the change of the call state is monitored by the monitor corresponding to the SIM card. Under the condition, the cooperative call can be carried out, so that the tablet personal computer collects and plays call voice in the process of carrying out operator call by the mobile phone.

Step B5: if the mobile phone monitors that the call state is changed from call transfer to idle through any one monitor, the cooperative call is ended.

When the mobile phone finishes the call of the operator currently carried by a certain SIM card (for example, hangs up the call of the operator carried by the SIM card), the call state of the SIM card is switched from idle in the call, and the change of the call state is also monitored by the monitor corresponding to the SIM card. The cooperative call may be ended at this time. And after the cooperative call is ended, the collection and the playing of the call voice are restored to the original state, namely, the call voice is switched back to the mobile phone for execution.

In the call state monitoring method provided by the embodiment of the application, a corresponding listener is registered for each SIM card according to the identifier of each SIM card in all the SIM cards in the mobile phone, and each listener can monitor the call state of the corresponding SIM card. Therefore, the mobile phone can monitor the call state of the SIM card in the main card slot through the monitor corresponding to the SIM card in the main card slot, and can monitor the call state of the SIM card in the auxiliary card slot through the monitor corresponding to the SIM card in the auxiliary card slot, so that the mobile phone can be ensured to carry out operator call no matter whether the mobile phone uses the main card slot or the SIM card in the auxiliary card slot, the call can be monitored, and accordingly, the cooperative call can be successfully realized. The service logic of the whole scheme is reasonable, the monitoring process is simple, convenient and accurate, and redundant processing and resource waste are avoided.
