Detailed Description

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

When the user removes electricity, the user needs to dial the telephone number of the called party by using the equipment with the SIM card so as to communicate with the called party. However, for some reasons, the user cannot conveniently use the device with the SIM card, that is, the device with the power-removing capability, so that the power cannot be successfully removed, and the power-removing limitation is high. For example, the user does not have a device with a SIM card, and the user cannot use the device with a SIM card. For another example, only the mobile phone has a SIM card, but the user is using the mobile phone (such as playing a game), and the user is inconvenient to use the mobile phone to remove electricity.

Therefore, in order to avoid power failure caused by inconvenient use of equipment with a SIM card by a user, the application provides a power failure method based on a distributed call system. As shown in fig. 1, the distributed talk system includes a master device 100 and at least one slave device 200, and the master device 100 establishes near field communication with each slave device 200, respectively. When the user needs to dial a call by using a target phone number corresponding to one SIM card in the master device 100, but is inconvenient to dial by using the master device 100, the user may input a call-making operation in the slave device 200, and the slave device 200 may send a call-going query request to the mobile phone first in response to the call-making operation. The call-out inquiry request is used for inquiring whether the target telephone number meets a preset call-out condition, and the preset call-out condition indicates that the telephone number can be called out. Then, the master device 100 receives the call-out query request, responds to the call-out query request, obtains the state information corresponding to the target phone number, judges whether the target phone number meets the preset call-out condition according to the state information corresponding to the target phone number, and generates a corresponding call-out query result. The power down query result indicates whether the target telephone number is capable of power down. The master device 100 transmits the power-down query result to the slave device 200. The slave device 200 receives the power-off inquiry result, and when the power-off inquiry result indicates that the target telephone number can be powered off, the slave device 200 sends a dialing command to the master device 100 to trigger the master device 100 to dial based on the target telephone number, so that the slave device 200 can realize power-off by sharing the communication capability of the master device 100, even if a user is inconvenient to use a device with a SIM card, the user can perform power-off by using a device without power-off capability, the power-off restriction is reduced, and the user communication experience is improved.

It should be understood that the master device 100 and the slave device 200 in the distributed telephony system in fig. 1 are connected based on a near field communication manner (i.e., based on a near field communication connection). The number of slave devices 200 in fig. 1 is only one example, and the present application does not limit the number of slave devices 200.

In some embodiments, the electronic device 300 may also include a high-fidelity (Hi-Fi) chip.

The SIM card interface 395 is for interfacing with a SIM card. The SIM card may be inserted into the SIM card interface 395 or removed from the SIM card interface 395 to enable contact and separation with the electronic device 300. The electronic device 300 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 395 may support Nano SIM cards, micro SIM cards, and the like. The same SIM card interface 395 can be used to insert multiple cards simultaneously. The types of the plurality of cards may be the same or different. The SIM card interface 395 may also be compatible with different types of SIM cards. The SIM card interface 395 may also be compatible with external memory cards. The electronic device 300 interacts with the network through the SIM card to realize functions such as communication and data communication. In some embodiments, the electronic device 300 employs esims, namely: an embedded SIM card. The eSIM card can be embedded in the electronic device 300 and cannot be separated from the electronic device 300.

The software system of the electronic device 300 (such as a master device or a slave device) may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the application, an Android system with a layered architecture is taken as an example, and the software structure of a master device or a slave device is illustrated.

Fig. 3 is a block diagram of a master device and a slave device according to an embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android ^TM system is divided into five layers, from top to bottom, an application layer, a service layer, a device connection layer, a device virtualization layer, and a hardware abstraction layer (hardware abstraction layer, HAL), respectively. For example, as shown in fig. 3, the host device may include five software layers, an application layer 10, a service layer 11, a device connection layer 12, a device virtualization layer 13, and a hardware abstraction layer 14. The slave device may include five software layers, an application layer 20, a service layer 21, a device connection layer 22, a device virtualization layer 23, and a hardware abstraction layer 24.

The application layer may include a series of application packages. As shown in fig. 3, the application layer 10 in the host device may include applications such as camera, bluetooth, video, short message, contact information management, device management, etc. The application layer 20 in the slave device may include camera, video, bluetooth, contacts, contact information management, etc. applications.

The contact application is responsible for dial interface management, such as displaying a dial interface, displaying a popup window including a list of SIM cards, so that a user can select to use a certain SIM card to make a call.

The contact information management application is responsible for managing contact information and synchronizing contact information between devices. For example, the master device (or a contact information management application in the master device) may store the newly added contact information. For another example, the master device may synchronize its stored contact information to the slave device.

The above-described device management application is used to manage the connection state, the on-line and off-line states, and the like of the slave devices, for example, the slave device that is determined to be in the on-line state, the slave device that is in the off-line state, and the like. The device management application may also be used to trusted authenticate the slave device.

The above-mentioned up status indicates that the master device discovers through near field communication (such as Wi-Fi, bluetooth, etc.), and determines that the device logs in the same account. If the account number of the equipment login is the same as the main equipment and is in the same local area network with the main equipment, the equipment is in an on-line state. The down-line state indicates that the master device has not found a device through near field communication or determines that the device has not logged into the same account. For example, when the tablet personal computer is turned on, the mobile phone discovers the tablet personal computer through bluetooth, and determines that the tablet personal computer logs in an account number logged in by the mobile phone, the tablet personal computer is in an online state, otherwise, the tablet personal computer is in a offline state.

The service layer may include a series of services. As shown in fig. 3, the service layer 11 in the host device may include a call framework, a service Profile, a control center, a cellular call service, and a call service. The service layer 21 in the slave device may include a service Profile, a control center, and a call service.

The call service is used for managing calls. As shown in fig. 4, the call service includes a SIM card information management module, a transmission module, a call management module, an audio management module, a device management module, and a collision management module.

The SIM card information management module is used for managing the SIM card information. Specifically, the SIM card information management module in the call service in the host device may manage all SIM card information in the host device. The SIM card information management module in the call service in the slave device may manage SIM card information in other devices (e.g., the master device) sent by the other devices. If the slave device itself is provided with a SIM card, the management of SIM card information in the call service in the slave device may also manage all SIM card information in the slave device.

The transmission module is used for transmitting related signaling/data to other devices (such as a master device) through a connection (Link) service. And the transmission module is used for receiving the signaling/data from other devices through the Link service and analyzing the signaling/data so as to carry out corresponding processing according to the type of the signaling/data.

The call management module is used for managing various operation signaling of the call, such as dialing signaling, answering signaling, hanging-up signaling and the like.

The audio management module is used for controlling the initialization time of the distributed fusion perception platform (distribute mobilesensing development platform, DMSDP) service and controlling the switching time of the call sound.

The device management module is used for registering device online and device offline monitoring with a device (device) Profile module to acquire the online and the offline states of the device. And the device management module is used for maintaining an online device list.

The conflict management module is used for determining whether the SIM card can be powered off currently.

The call framework, also called call management service, is a native service. The call management service is responsible for managing incoming call situations. Specifically, when the host device calls, the call management service determines whether the host device needs to make a call prompt, whether to start a call interface, and the like. For example, when the master device turns on the incoming call intercept function, it indicates that the master device refuses to answer all incoming calls. When the main device is in call, the call management service determines that the main device does not carry out call prompt.

The control center is responsible for displaying all devices in the near field range of a certain device, the communication connection relation between the device and the devices in the near field range, the device condition of the incoming call of the device, and the like. The control center may also disconnect the communication connection between the device and the other device, newly add the communication connection between the device and the other device, and the like based on the operation of the user.

The cellular telephony service described above is responsible for managing cellular telephones, i.e., cellular network-based telephones. Illustratively, the cellular network includes 2G, 3G, 4G, and the like.

The service Profile is responsible for managing the online and offline of the device, the registered services in the service Profile in the other device, and the like. For example, in order for a host device to support distributed telephony service capabilities, a telephony service in the host device may register with the service Profile. The service Profile in the master device may perceive whether the call service in the slave device is registered with the service Profile in the slave device. The account number of the login of the slave device is the same as the account number of the login of the master device when the device is online.

In some embodiments, the service layer may further include an application programming interface (application programming interface, API) module. The API module may provide an API interface or the like for an application of the application layer.

The device connection layer and the device virtualization layer are layers for distributed services (such as distributed call services). As shown in fig. 3, the device connection layer 12 in the master device may include Link services. The device connection layer 22 in the slave device may include Link services.

The Link service is used for providing the capability of transmitting data and signaling between different devices through near field communication. For example, one device may send signaling/data to a Link service in another device through the Link service in that device.

In some embodiments, the device connection layer 12 in the master device may further include a device Profile and a distributed rights management module. The device connection layer 22 in the slave device may include a device Profile.

For example, the device Profile may be provided with security capabilities, data transmission capabilities, and connection management capabilities. The security capability means that the device can be trusted authenticated to determine whether the device is secure. The data transmission capability means that data transmission between devices can be performed through near field communication. Connection management capabilities mean managing devices that establish near field connections. For example, the device Profile in the master device knows the slave device that has established a near field connection with the master device.

In some embodiments, device Profile may be device management capable. The device management capability means that the device can be managed in the up-down state, i.e. the up-down state of the device can be perceived.

It should be appreciated that the above device Profile and service Profile constitute a distributed Profile.

The distributed rights management module is responsible for querying rights of the slave device, such as whether the slave device is allowed to be discovered, connected, transmit data, etc. The distributed rights management module may be provided with device management capabilities.

It should be understood that the capabilities provided by each module in the device connection layer described above are only one example, and each module may have other capabilities, which the present application is not limited to.

As shown in fig. 3, the device virtualization layer 13 in the master device may include DMSDP services. The device virtualization layer 23 in the slave device may include DMSDP services.

Illustratively, DMSDP services may also be referred to as audio virtualization services, which are used to enable the continuation of telephony voice data. The devices may stream call voice data between the devices by invoking the virtual device capabilities provided by DMSDP. For example, the call sound can be switched from the master device to the slave device, and the call sound can be switched from the slave device back to the master device.

In some embodiments, the device virtualization layer 13 in the host device may also include display virtualization services, camera virtualization services, and the like.

The HAL layer is used for abstracting hardware in the hardware layer and providing hardware access service upwards. As shown in fig. 3, the HAL layer 14 in the host device may comprise RILC (i.e. RIL-C or RIL-c++) HAL, audio (Audio) HAL, near field communication HAL. The HAL layer 24 in the slave device may comprise audio and near field communication HALs.

Wherein RILC is part of a Radio Interface Layer (RIL) INTERFACE LAYER. The RIL is a bridge for communication between the modem and the Android system. RIL can be divided into two parts, one part is RILJ (namely RIL-Java) framework, which is realized by Java language; the other part is RILC, which is located at the hardware abstraction layer and is implemented in the C language or the c++ language.

AudioHAL are used to take care of the transmission of the audio streams associated with the call inside the device.

The near field communication HAL is used to implement near field communication functions. For example, the near field communication HAL may comprise Bluetooth HAL, wi-FiHAL, NFCHAL, etc. The Bluetooth HAL is used for realizing Bluetooth communication functions. Wi-FiHAL is used to implement Wi-Fi communication functions. NFCHAL are used to implement NFC communication functions.

In some embodiments, the HAL layer in the host device may also include a display (dispaly) HAL, a camera HAL, and the like.

As shown in fig. 3, the hardware layer in the master device may include a Modem, a Hi-Fi chip, and a near field communication chip. The hardware layers in the slave device may include a near field communication chip, a speaker (speaker), a microphone, and the like.

By way of example, the near field communication chip may include a Bluetooth chip, a Wi-Fi chip, an NFC chip, and the like.

In some embodiments, the hardware layer 14 in the host device may also include a display screen, a camera, a speaker, a microphone, and the like.

In some embodiments, the service layer (e.g., service layer 11, service layer 21) may also act as a framework layer.

The device connection layer (e.g., the device connection layer 12 and the device connection layer 22) and the device virtualization layer (e.g., the device virtualization layer 13 and the device virtualization layer 23) may belong to Android runtime (Android ^TM runtime) and a system library. The framework layer provides APIs and programming frameworks for application layer applications. The application framework layer includes a number of predefined functions. Android ^TM runtime includes a core library and virtual machines.

Android ^TM runtime is responsible for scheduling and management of the Android system. The core library consists of 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 framework layer run in virtual machines. The virtual machine executes java files of the application layer and the framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

It will be appreciated that the layers and components contained in the layers in the structure shown in fig. 3 do not constitute a specific limitation on the master or slave. In other embodiments of the application, the structure may include more or fewer layers than shown, and more or fewer components may be included in each layer, as the application is not limited.

The application provides a power-off method based on a distributed call system. The distributed telephony system includes a master device and at least one slave device. The master device is a device provided with a SIM card and is connected to each of the at least one slave device based on near field communication (i.e. near field connection). When a user makes a call on any one of the at least one slave device, the any one slave device may display a SIM card list, which may include all SIM card information on the master device, for the user to select a target SIM card for use in powering down. After that, any one slave device can utilize the device (such as the master device) where the target SIM card is located to perform power-off, so that any one slave device can dial by sharing the communication capability of the master device, even if any one slave device does not have the SIM card, that is, does not have the power-off capability, any one slave device can still realize the communication of an operator, reduce the communication restriction and improve the communication satisfaction of users.

In one example, the slave device and the master device in the distributed call system log in the same account. As the near field connection is Wi-Fi connection, each slave device in the distributed call system not only logs in the same account number with the master device, but also is in the same local area network with the master device.

In another example, in order to improve the security of device communication, the slave devices in the distributed communication system further pass trusted authentication. For example, after the master device establishes a near field connection with one device, the master device may perform trusted authentication on the device to obtain an authentication result of the device. And after the authentication result of the device is that the authentication is successful, the device is indicated to be safe and trusted, and the device can be a slave device of the master device. And after the authentication result of the equipment is authentication failure, the fact that the trusted authentication of the equipment is not passed is indicated, the safety of the equipment is low, and the equipment part is a slave equipment of the master equipment. Of course, the trusted authentication may also be performed after the master device establishes a near field connection with the device and logs in to the same account.

The trusted authentication may be, for example, key authentication. The key authentication process may be: the master device encrypts preset data through a private key to obtain encrypted data. The master device may then send the encrypted data to the device. The device then receives the encrypted data and decrypts the encrypted data via the credentials of the logged-in account. The device then transmits the decrypted data to the master device. The host device then receives the decrypted data. And comparing the standard decrypted data corresponding to the preset data with the decrypted data, wherein the standard decrypted data is correct data obtained after the encrypted data is decrypted. If the two are consistent, the certificate of the device is correct, and the master device determines that the authentication result of the device is authentication success. If the two are inconsistent, indicating that the data of the device is wrong, the master device determines that the authentication result of the device is authentication failure.

The preset data may be at least one of a key and a character (such as a number, a text, and a symbol).

It should be noted that, the above-described key authentication process is one implementation manner of key authentication, and key authentication may be implemented by other implementation manners, where the manner of using the key in the authentication process belongs to the implementation manner of password authentication. And the above-mentioned manner of trusted authentication may be other manners as well. For example, the master device determines whether the device is in a preset unsafe list, if so, the master device determines that the authentication result of the device is authentication failure, and the application does not limit the manner of trusted authentication.

In the following, taking the above main device as a mobile phone and the slave device as a tablet computer as an example, the de-electrifying presentation method provided by the embodiment of the application is specifically described with reference to the accompanying drawings. As shown in fig. 5, the method comprises the steps of:

S501, responding to a first operation on a dialing interface displayed on a tablet computer by a user, and displaying a SIM card list on the tablet computer.

The SIM card list comprises second information of at least one SIM card corresponding to the mobile phone identifier. The SIM card corresponding to the mobile phone identifier represents the SIM card in the mobile phone corresponding to the mobile phone identifier available to the tablet computer.

For example, the second information of the SIM card may include at least one of an identifier of the SIM card, a phone number corresponding to the SIM card, and an identifier of a device to which the SIM card belongs (e.g., the mobile phone identifier). The identification of the SIM card indicates that the SIM card is in the position of the card slot in the mobile phone, for example, the identification of the SIM card is card 1, which indicates that the SIM card is in the card slot 1 in the mobile phone.

In an example, the dial interface displayed on the tablet computer includes a preset button, and the first operation may be a click operation of the preset button on the dial interface by a user. For example, the preset button is a dial button (dial button 11 in dial interface 10 shown in fig. 6). When the user wants to make a call using the SIM card in the handset, the user can click on the make button. Here, the operation of clicking the dial button by the user is the first operation described above. In response to the user clicking the dial button 11, the tablet computer displays a pop-up window including the SIM card available to the tablet computer, such as displaying a dial interface 20 as shown in fig. 7, the dial interface 20 including a list 21 of SIM cards. The SIM card list 21 includes the identification of the SIM card in the handset and the phone number corresponding to the SIM card.

In some embodiments, the SIM card list may further include a device identifier of a device to which the SIM card belongs, for example, the SIM card list 24 shown in fig. 8 includes a mobile phone identifier 25.

In another example, the dial interface displayed by the tablet computer may include at least one call number, which is the number that the tablet computer calls or listens to. When the user wants to dial a call number in the dial interface, the call number may be clicked, such as by clicking on the call number in dial interface 10 shown in fig. 9. Here, the operation of clicking the call number by the user is the first operation.

In some embodiments, the second information of at least one SIM card corresponding to the mobile phone identifier on the tablet computer may be obtained by the tablet computer from the information of the SIM card sent by the mobile phone, that is, the second information of the SIM card may be sent by the mobile phone.

In one implementation, the second information of at least one SIM card corresponding to the mobile phone identifier on the tablet computer may be sent when the mobile phone is online on the tablet computer. As shown in fig. 10, the transmission process of the second information of the SIM card may include S601 to S602.

S601, when the mobile phone determines that the tablet personal computer is in an online state, information of each SIM card corresponding to the mobile phone identification is sent to the tablet personal computer.

The information of the SIM card may include the second information of the SIM card.

In some embodiments, the information of the SIM card may further include a card status of the SIM card. The information of the SIM card may include at least one of an identification of the SIM card, a phone number corresponding to the SIM card, a card status, and a device identification of a device to which the SIM card belongs, for example.

Wherein the card status includes a ready status or a not ready status. When the SIM card is not in place or has poor signal, the card state of the SIM card is in an unavailable state. When the SIM card is in place and the signal is strong, the card state of the SIM card is available.

Illustratively, when the signal strength of the SIM card is less than the preset signal strength threshold, the signal strength of the SIM card is poor. When the signal intensity of the SIM card is larger than or equal to a preset signal intensity threshold value, the signal intensity of the SIM card is strong.

In some embodiments, the mobile phone may detect whether the SIM card in the mobile phone is in place through a detection method such as a software detection method, a hardware detection method, or the like. For example, the hardware detection method is current detection through a SIM card holder, or micro-switch or photoelectric detection. The software detection method is that the mobile phone performs command interaction with the SIM card through a related detection program, and when the mobile phone receives the correct response of the SIM card through the detection program, the mobile phone can determine that the SIM card is in place.

In some embodiments, the mobile phone discovers that the tablet pc logs in to the same account through near field communication (such as bluetooth, wi-Fi, etc.), and the mobile phone can determine that the tablet pc is in an online state. That is, when the tablet computer and the mobile phone establish near field connection, and the tablet computer and the mobile phone log in the same account, the tablet computer is in an online state. For example, the tablet computer and the mobile phone are in the same local area network, the tablet computer and the mobile phone log in the same account, and the tablet computer is in an online state.

S602, the tablet personal computer receives information of each SIM card corresponding to the mobile phone identifier and stores the information of each SIM card corresponding to the mobile phone identifier.

In another implementation manner, the at least one SIM card corresponding to the mobile phone identifier on the tablet computer may be sent when a card state of the SIM card on the mobile phone changes. As shown in fig. 10 described above, the transmission process of the second information of the SIM card may include S603-S604.

S603, when the card state of the SIM card in the mobile phone changes, the mobile phone sends the latest information of the SIM card with the changed card state to the tablet computer.

S604, the tablet personal computer receives the SIM card information with the changed card state, and updates the SIM card information with the changed card state in the SIM card information corresponding to the mobile phone identifier stored in the tablet personal computer to the latest information.

The information of each SIM card corresponding to the mobile phone identifier stored in the tablet computer may be sent after the mobile phone is on line in the tablet computer.

Illustratively, the change in card status includes a change in card status from an unavailable status to an available status or a change in card status from an available status to an unavailable status.

The implementation procedure of S603 to S604 described above is described below in connection with a specific example.

The SIM cards in the handset include a SIM card 1 and a SIM card 2. When the mobile phone detects that the card state of the SIM card 1 is changed from the unavailable state to the available state, the mobile phone sends the current information of the SIM card 1 to the tablet personal computer. The current information includes the identity of the SIM card 1, the corresponding phone number of the SIM card 1 and the available status. The tablet computer updates the locally stored information of the SIM card 1 to the current information, that is, the card state in the locally stored information of the SIM card 1 of the tablet computer becomes the available state.

In some embodiments, when a first operation of a user on a dialing interface displayed on a tablet computer is received, for each SIM card corresponding to the mobile phone identifier, the tablet computer obtains second information of the SIM card from information of the SIM card, and displays the second information including each SIM card corresponding to the mobile phone identifier.

That is, the SIM card list includes the second information of each SIM card in the mobile phone, so as to realize all display of the SIM cards of the mobile phone, so that the user can select the phone number for power-off, and the power-off requirement of the user is met.

In this embodiment, the second information of the SIM card may further include a card status of the SIM card, and correspondingly, the SIM card list also includes the card status of the SIM card, so that a user of the tablet computer may learn whether the SIM card is available.

In other embodiments, the information of the SIM card includes a card status. When a first operation of a user on a dialing interface displayed on a tablet personal computer is received, the tablet personal computer acquires SIM cards with available card states from the SIM cards corresponding to the mobile phone identifiers, and displays a SIM card list comprising second information of the SIM cards with the available card states corresponding to the mobile phone identifiers.

That is, only the second information of the SIM card in the usable state is included in the SIM card list. That is, the tablet personal computer provides the available SIM card for the user to select, so that the user is prevented from selecting the unavailable SIM card to dial a call.

S502, responding to the selection operation of the user on the target SIM card in the SIM card list, and sending an electricity inquiry request to the mobile phone by the tablet personal computer.

The power-off query request comprises first information of the target SIM card. The power-off inquiry request is used for triggering the mobile phone to inquire whether the target SIM card can be powered off.

The first information of the target SIM card includes an identifier of the target SIM card and/or a phone number corresponding to the target SIM card. For example, the first information of the target SIM card includes an identification of the target SIM card.

For another example, the first information of the target SIM card includes a phone number corresponding to the target SIM card.

For another example, the first information of the target SIM card includes an identification of the target SIM card and a phone number of the target SIM card.

In some embodiments, in response to a first operation on a dial-up interface displayed on a tablet computer by a user, if only one SIM card is available to the tablet computer (for example, only one SIM card exists in the mobile phone, only one SIM card in an available state exists in the SIM cards in the mobile phone), the tablet computer may not display the above-mentioned SIM card list without selecting which SIM card to use for power-down, but may directly use the one SIM card as a target SIM card, and send a power-down query request to the mobile phone directly, so that the mobile phone determines whether the target SIM card is power-down, thereby improving power-down efficiency.

S503, the mobile phone responds to the power-off inquiry request to acquire the state information of the target SIM card.

In the embodiment of the application, when the user selects the second information of one SIM card from the SIM card list, the SIM card is indicated to be the SIM card which the user wants to use when the user removes electricity, and the tablet computer can take the SIM card selected by the user as the target SIM card. Because the target SIM card on the mobile phone may not be powered on currently, the tablet pc firstly queries whether the target SIM card can be powered on or not to the mobile phone, i.e. the tablet pc sends a power on query request to the mobile phone.

And then, when the mobile phone receives the power-off inquiry request, acquiring first information of the target SIM card in the power-off inquiry request, so that the mobile phone can determine the SIM card corresponding to the first information (namely the target SIM card) by utilizing the first information.

And then, the mobile phone detects the target SIM card to obtain the state information of the target SIM card so as to determine whether the target SIM card can be powered off or not by utilizing the state information of the target SIM card.

The state information of the target SIM card indicates whether the target SIM card is in an available state and/or whether the target SIM card is in a call state. When the mobile phone uses the SIM card to make or receive a call, the SIM card is in a call state. When the mobile phone does not use the SIM card to make or receive a call, the SIM card is not in a call state.

S504, the mobile phone judges whether the target SIM card meets the preset condition of no power-off based on the state information of the target SIM card, and generates a power-off inquiry result of the target SIM card.

The power-off query result indicates whether the target SIM card can be powered off or not.

The preset no power-down condition includes, for example, that the SIM card is in an unavailable state or that the SIM card is in a talking state.

In one example, the status information of the target SIM card indicates whether the target SIM card is in an available state. The preset no-power-down condition includes the SIM card being in an unavailable state. Correspondingly, when the state information of the target SIM card indicates that the target SIM card is in an unavailable state, the mobile phone indicates that the target SIM card cannot make a call, and the mobile phone determines that the target SIM card meets the preset condition of no power-off, so that the power-off query result of the target SIM card indicates that the target SIM card cannot be powered off.

When the state information of the target SIM card indicates that the target SIM card is in a usable state, the mobile phone can determine that the target SIM card does not meet a preset power-off condition. Thus, the power-down inquiry result of the target SIM card indicates that the target SIM card can be powered down.

In another example, the status information of the target SIM card indicates whether the target SIM card is in a call state. The preset no-power-off condition includes that the SIM card is in a call state. Correspondingly, when the state information of the target SIM card indicates that the target SIM card is in a call state, the mobile phone indicates that the target SIM card can not dial a call, and the mobile phone determines that the target SIM card meets the preset condition of no power-off, so that the power-off query result of the target SIM card indicates that the target SIM card can not be powered off.

When the state information of the target SIM card indicates that the target SIM card is not in a call state, the mobile phone can determine that the target SIM card does not meet the preset condition of no power-off. Thus, the power-down inquiry result of the target SIM card indicates that the target SIM card can be powered down.

In another example, the status information of the target SIM card indicates whether the target SIM card is in a call state and is in an available state. The preset no-power-off condition includes that the SIM card is in a call state or the SIM card is in an unavailable state. Correspondingly, when the state information of the target SIM card indicates that the target SIM card is in a call state or the state information of the target SIM card indicates that the target SIM card is in an unavailable state, the mobile phone determines that the target SIM card meets the preset no-power-off condition, and accordingly the power-off query result of the target SIM card indicates that the target SIM card cannot be powered off.

When the state information of the target SIM card indicates that the target SIM card is not in a call state and the state information of the target SIM card indicates that the target SIM card is in an available state, the mobile phone may determine that the target SIM card does not satisfy a preset no-power-off condition. Thus, the power-down inquiry result of the target SIM card indicates that the target SIM card can be powered down.

In some embodiments, the power-down query result includes power-down result prompt information. The power-off result prompt information comprises power-off capable prompt information or power-off unavailable prompt information. The power-off capable indication information indicates that the target SIM card can be powered off, and the power-off incapable indication information indicates that the target SIM card cannot be powered off, namely that a user cannot use the SIM card to successfully dial a call, so that the user of the tablet personal computer can intuitively know whether the target SIM card can be powered off.

In some embodiments, when the power-down query result includes the power-down disabled indication information, the power-down query result may further include a power-down disabled reason, where the power-down disabled reason is a reason that causes the target SIM card to satisfy a preset power-down disabled condition. For example, the status information of the target SIM card indicates whether the target SIM card is in a call state. The preset no-power-off condition includes that the SIM card is in a call state. When the target SIM card is in a call state, the reason that the target SIM card cannot be powered off can be that the target SIM card is in the call, so that a user of the tablet personal computer can intuitively and clearly know the reason that the target SIM card cannot be powered off, and the user can timely handle the abnormality, such as powering off by using other SIM cards, or solve the problem of the target SIM card in the second equipment.

S505, the mobile phone sends a power-off query result of the target SIM card to the tablet personal computer.

For example, the third information of the target SIM card includes an identification of the target SIM card. For another example, the third information of the target SIM card includes a phone number corresponding to the target SIM card. For another example, the third information of the target SIM card includes an identification of the target SIM card and a phone number of the target SIM card.

In the embodiment of the application, when the mobile phone obtains the power-off query result of the target SIM card, the power-off query result of the target SIM card is returned to the tablet personal computer. And then, when the power-off query result of the target SIM card indicates that the target SIM card can be powered off, the tablet computer indicates that the target SIM card can normally dial a call, and the tablet computer sends a dialing signal to the mobile phone so as to trigger the mobile phone to use the target SIM card to perform power-off.

In some embodiments, in order to enable a user of the tablet computer to intuitively acquire the power-off condition, when the power-off query result of the target SIM card indicates that the target SIM card can be powered off, the target SIM card is indicated to be based on the power-off, and the tablet computer displays a first call interface, so that the user can intuitively acquire that the target SIM card is utilized to perform power-off, and the situation that the user does not utilize the target SIM card to power off for the tablet computer is avoided.

Generally, after the device is powered off based on the SIM card, the called party will not start ringing, i.e. the call state of the SIM card is initially the calling (dialing) state. Thus, in one example, the first call interface may include a reminder (such as reminder 31 in first call interface 30 shown in fig. 11). The prompt information indicates that the call-out is in a call state, namely, the call state of the target SIM card is in the call state, so that a user can intuitively know the call-out state.

S510, when the call state of the target SIM card is updated to be in a ringing state, the mobile phone sends the audio data of the called equipment to the tablet computer.

S511, the tablet personal computer receives the audio data of the called device and plays the audio data of the called device through a loudspeaker in the tablet personal computer.

In the embodiment of the application, after the mobile phone dials a call based on the target SIM card, the initial call state of the target SIM card is a call state, and the called party side is not ringing. After a certain time, the called party starts ringing, and at this time, the Modem in the mobile phone can know that the called party has ringing, that is, the call state of the target SIM card is updated to the ringing state.

When the call state of the target SIM card is a ringing state, the called equipment is indicated to have sound, the mobile phone can switch the sound to the tablet personal computer side, namely, the received audio data of the called equipment can be forwarded to the tablet personal computer, so that the tablet personal computer can play by using a loudspeaker in the tablet personal computer, and a user of the tablet personal computer can successfully acquire the power-off state.

Wherein, the audio data of the called device comprises the bell of the called device, such as color bell, beep, etc.

In some embodiments, when the call state of the target SIM card is updated to the ringing state, the mobile phone may want the tablet computer to send the call state of the target SIM card, that is, the ringing state.

And then, the tablet computer receives the call state of the target SIM card.

And then, the tablet personal computer can display a second call interface corresponding to the call state. The second call interface may include a reminder message (such as reminder message 41 in second call interface 40 shown in fig. 12). The prompt information indicates that the call is in a ringing state, namely, the call state of the target SIM card is in the ringing state, so that a user can intuitively know the call state, and timely prompt of the call state of the called equipment is realized.

In some embodiments, the call interface (e.g., the first call interface and the second call interface) displayed by the tablet computer may further include prompt information for prompting the device for actually using the mobile phone 1 to be powered off, where the prompt information may include a device identifier of the device for actually using the mobile phone to be powered off, and the prompt information 49 is shown in fig. 11 or fig. 12, where the prompt information 49 indicates that the tablet computer is currently powered off by using the mobile phone 1, so that the user may intuitively know the actual power-off situation.

S512, when the power-off query result of the target SIM card indicates that the target SIM card cannot be powered off, the tablet computer displays the power-off disabled indication information on the dialing interface.

For example, when the power-off query result of the target SIM card indicates that the target SIM card cannot be powered off, it indicates that the tablet computer cannot utilize the target SIM card to power off, and the tablet computer may display a popup window on a dial interface displayed on the tablet computer, where the power-off incapacitation indication information 42 as shown in fig. 13 exists in the popup window, so that a user may intuitively learn that the target SIM card cannot be powered off.

In some embodiments, in order to enable the user to know the reason of the power failure, the tablet pc may display the reason for the power failure (the reason for the power failure 43 shown in fig. 14) on the dial interface, so that the user may clearly know the reason for the power failure of the target SIM card, and further, may enable the user to determine whether to adjust the target SIM card in the mobile phone in time.

In some embodiments, when the mobile phone is in the offline state, when the device list is displayed on the tablet computer, the device list does not include the second information of the SIM card of the mobile phone any more, so that the user is prevented from selecting the SIM card which cannot be powered on to place a call, and interference to the user is avoided.

In this embodiment, when the mobile phone is in the offline state, the tablet computer may remove all the SIM card information corresponding to the mobile phone identifier from the locally stored SIM card information.

For example, if the near field connection between the mobile phone and the tablet computer is disconnected (e.g., the mobile phone closes bluetooth, wi-Fi) or the mobile phone exits the account, the mobile phone is in a offline state.

In the embodiment of the application, when the mobile phone receives the audio data of the called equipment, the loudspeaker in the mobile phone does not acquire and play the audio data of the called equipment, so that the interception of the audio stream is realized, audioHAL in the mobile phone can directly read the audio data of the called equipment from the Hi-Fi chip in the mobile phone, and the audio data of the called equipment is transmitted to DMSDP service in the mobile phone. Then, DMSDP service in the mobile phone sends audio data of the called device to DMSDP service in the tablet computer by using connection service. Then, DMSDP services in the tablet computer can play audio data of the called device through a loudspeaker in the tablet computer, so that a user of the tablet computer can know the calling condition of the called device. And because the mobile phone can not play the audio data of the called equipment, the interference to the user of the mobile phone can be avoided.

It should be understood that when the called device listens to the power-off, the tablet computer establishes a call with the called device through the mobile phone. The mobile phone service transmits the voice of the two parties of the call to the other party, for example, the mobile phone receives the first voice data collected by the microphone in the tablet computer and sent by the tablet computer, and sends the first voice data to the called equipment, so that the user of the called equipment can hear the speaking voice of the other party. For another example, the mobile phone sends the second voice data sent by the called device to the tablet computer, so that the user of the tablet computer can hear the speaking voice of the other party, and normal conversation is ensured. And the mobile phone can not send the sound collected by the microphone in the mobile phone to the opposite side equipment and can not play the second voice data, so that the interception of the audio stream at the mobile phone side is realized, and the disclosure of privacy can be avoided.

It can be understood that when the mobile phone is used for power-off, the tablet computer can still share the communication capability of the mobile phone for power-off even if the mobile phone is in a black screen state. And in the process of removing electricity, the mobile phone is also in the process of removing electricity. Therefore, the mobile phone can also be in a call interface display or a call prompt message display on a status bar. For example, as shown in connection with fig. 17, the handset is in a black screen state. When the user performs the relevant triggering operation, the mobile phone is on screen, and a screen locking interface as shown in fig. 18 is displayed, and the screen locking interface may include a call prompt message 90 to prompt the user that the mobile phone is being powered off.

It should be noted that, the above description describes that the tablet pc displays the SIM card of one device (such as the mobile phone) so that the SIM card of the mobile phone is used for the process of removing electricity, and there are situations that the tablet pc can use any one of the SIM cards in multiple devices for removing electricity. In this case, the device list includes SIM cards of each device that the tablet pc can utilize, so that a user can select a SIM card used for power-off from SIM cards of a plurality of devices, thereby reducing power-off restriction and improving call experience of the user. Each device in the plurality of devices corresponds to a master device of the tablet computer, for example, each device in the plurality of devices establishes a near field communication connection with the tablet computer and logs in the same account. As shown in fig. 19, the tablet computer displays a SIM card list 61 on the dial interface 60, the SIM card list 61 displaying second information of SIM cards in a plurality of devices including the mobile phone 1 and the mobile phone 2, that is, the device list 61 includes second information of SIM cards of the mobile phone 1 and second information of SIM cards of the mobile phone 2.
