In short, the proxy mode is to set a proxy object as an intermediate proxy to control access to the original target object, so as to achieve the purposes of enhancing the function of the original target object and simplifying the access flow.

It may be appreciated that the method for cellular communication capability continuation described in the embodiments of the present application may be applied to a variety of scenarios, for example, the variety of scenarios may include: a near field scene as described in the corresponding embodiment of fig. 1, a far field scene as described in the corresponding embodiment of fig. 2, etc.

Exemplary, fig. 1 is a schematic view of a scenario provided in an embodiment of the present application. In the embodiment corresponding to fig. 1, an electronic device is taken as an example of a mobile phone, and this example does not limit the embodiments of the present application.

As shown in fig. 1, the scenario may include a first device 101 disposed in a basement, and a second device 102 disposed in a living room, where at least one SIM card may be disposed in the first device 101, and the second device 102 may not be disposed with or without a SIM card. Wherein the cellular network signal of the first device 101 in the basement is weak or has no cellular network signal, and the cellular network signal of the second device 102 in the living room is good.

It may be appreciated that, in the near field scenario shown in fig. 1, the first device 101 and the second device 102 may both establish a communication connection by being connected to the same WIFI or the like, and in the scenario in which the communication connection is established by being connected to the same WIFI, the router 103 may implement data forwarding between the first device 101 and the second device 102.

In the near field scenario as in fig. 1, since the cellular network signal of the basement is weak, it is difficult for the user to independently perform cellular communication services such as sending and receiving a short message or making a call using the first device 101.

Fig. 2 is a schematic diagram of another scenario provided in an embodiment of the present application. As shown in fig. 2, the scenario may include: a first device 201 located at a company, and a second device 202 located at home; at least one SIM card may be disposed in the first device 201, and the second device 102 may not be disposed with a SIM card or may be disposed with a SIM card; a modem2 (or simply M2) may be provided in the first device 201, and a modem1 (or simply M1) may be provided in the second device 202. Wherein the cellular network signal of the first device 201 located at the company is weak or has no cellular network signal, the cellular network signal of the second device 102 located at home is good.

It may be understood that the SIM card of the first device described in the embodiments of the present application may be understood as one of the SIM cards in the first device with a weaker cellular network, or referred to as the first SIM card; the modem of the second device described in the embodiments of the present application may be understood as a modem in which one of the cellular networks in the second device is better. Wherein the one modem is a modem in the second device for providing a connection for cellular communication capabilities for one of the SIM cards in the first device (or may be understood as M1 in fig. 2).

It can be understood that, in the far-field scenario as shown in fig. 2, the first device 201 and the second device 202 may be connected to respective corresponding WIFI or the like to ensure data service, so that the first device 201 and the second device 202 may be connected to a communication service cloud through the data service, and the functions of data interaction, device authentication, establishment of a data channel and the like between the first device 201 and the second device 202 are implemented based on the communication service cloud.

In a possible implementation manner, whether the first device 101 and the second device 102 in fig. 1 are connected to the same WIFI or the like to establish a communication connection, or the first device 201 and the second device 202 in fig. 2 are connected to respective corresponding WIFI or the like to establish a communication connection, the purpose is to ensure data communication between the first device and the second device. Thus, in the scenario shown in fig. 1 or fig. 2, the communication connection between the first device and the second device may also be established through another SIM card in the first device having a cellular network (or may be understood as having a better cellular network signal), or other wireless or wired manner, which is not limited in the embodiment of the present application.

In the far-field scenario corresponding to fig. 2, when the cellular network signal of the company is weak, it is difficult for the user to independently perform cellular communication services such as sending and receiving a short message or making a call using the first device 201.

In general, by integrating the scenes corresponding to fig. 1 and fig. 2, the network coverage condition in the environment with weak network signals can be improved by installing a micro base station or setting a signal amplifier in the environment with weak network signals. However, the above-mentioned manner of improving the network signal in the environment by installing the micro base station or setting the signal amplifier is complicated, and the location of installing the micro base station or setting the signal amplifier cannot be flexibly adjusted.

In view of this, an embodiment of the present application provides a method for connecting cellular communication capabilities, where a first device sends a first request to a second device through an established connection; the first request is for indicating that the first device requests access to a modem processor modem of the second device; the first device receives a second request from the second device; the second request is used for indicating the second equipment to request remote access to a first Subscriber Identity Module (SIM) card of the first equipment; the first equipment sends first SIM card information of the first equipment to the second equipment after receiving the second request; the first device sends first information to the second device so as to send the first information to the third device through the modem of the second device based on the first SIM card information through the cellular network; the first information is associated with a first service, the first service being associated with a first device and a third device; the first device receives second information from the second device; the second information includes: the modem of the second device receives information from the third device via the cellular network based on the first SIM card information, the second information being associated with the first service. In this way, by using the modem of the second device and the SIM card of the first device, the first device in an environment where the carrier network has no signal or the network signal is weak can use the second device with cellular communication capability in an environment where the other network signal is good to perform connection of the cellular communication capability.

It can be appreciated that, as shown in fig. 2, the method for continuing cellular communication capability provided in the embodiment of the present application may implement transferring a SIM card in the first device 201 to the second device 202 for use, and implement transferring M1 in the second device 202 to the first device 201 for use.

Wherein, the first request can be understood as a remote modem switching instruction described in the embodiment of the present application; the second request may be a remote SIM switch instruction as described in embodiments of the present application.

In some scenarios, the first device and the second device may implement the transfer of the cellular communication service through the transfer of application-side data, so that the first device needs to use the cellular communication capability of the second device to perform communication.

The cellular communication service is exemplified as a call service. For example, the first device and the second device are both configured with a phone application for transferring call services, and when the SIM card of the second device receives a phone call, a control flow and a data flow of the phone call are transferred to the phone application configured on the first device through the phone application configured on the second device, so that a user can receive the phone call through the phone application of the first device.

It can be understood that, in a scenario in which transfer of the cellular communication service is implemented by forwarding of application-side data between the first device and the second device, the first device uses the SIM card of the second device to receive the call service, and the phone number used in the call service is the phone number of the second device, which is not the phone number currently being used by the first device.

According to the method for continuing the cellular communication capability, which is provided by the embodiment of the application, the first equipment can receive the call service by utilizing the SIM card of the first equipment, and the telephone number used in the call service is the telephone number of the first equipment so as to ensure the cellular communication service of the first equipment.

It can be understood that, in a scenario in which the transfer of the cellular communication service is implemented by forwarding data on the application side between the first device and the second device, the first device and the second device need to install the same application (for example, a telephony application), and each application can only implement the transfer of one service; furthermore, a first device in this scenario may be understood as a display and playback device, with the actual business functions running on the second device.

The method for continuing the cellular communication capability provided in the embodiment of the present application is equivalent to that a new modem (the new modem can be understood as a modem of a second device used remotely) is virtually displayed on the first device, and a real operator network is registered, so that the awareness from the user plane can be recovered for the network signal, and the capabilities of calling/short messages and the like are also recovered. At the same time, all applications installed on the first device are completely unaware of the continuation of the cellular communication capability and the cellular communication functionality provided by the second device is completely consistent with the cellular communication functionality used by the user on the first device.

It can be understood that, in the scenario of implementing the transfer of the cellular communication service by the transfer of the application-side data between the first device and the second device, all elements (contacts, phone numbers, etc.) related to the call service are provided by the second device, and various data (such as a recording, a call record, etc.) generated in the call are recorded in the second device.

In the method for continuing the cellular communication capability provided in the embodiment of the present application, whether the signal continuation occurs is completely not perceived by an application in the first device, and various data (such as a recording, a call record, etc.) generated in all calls are recorded in the first device, and meanwhile, no service trace is left in the second device.

It is understood that the first device or the second device may also be referred to as an electronic device, a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. For example, the first device or the second device may be: mobile phone (mobile phone), smart television, wearable device, tablet (Pad), computer with wireless transceiver function, virtual Reality (VR) device, augmented reality (augmented reality, AR) device, etc. The embodiments of the present application do not limit the specific technology and the specific device configuration adopted by the first device or the second device.

Therefore, in order to better understand the embodiments of the present application, the structure of the electronic device of the embodiments of the present application is described below.

Fig. 3 is a schematic hardware structure of an electronic device according to an embodiment of the present application.

The electronic device shown in fig. 3 may be the first device described in the embodiment of the present application, or may also be the second device described in the embodiment of the present application.

Modem 210A may include a modulator and demodulator. The modulator is used for modulating the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low frequency baseband signal to the baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. The application processor outputs sound signals through an audio device (not limited to speakers, receivers, etc.), or displays images or video through the display screen 294. In some embodiments, modem 210A may be a stand-alone device. In other embodiments, modem 210A may be provided in the same device as mobile communication module 250 or other functional modules, independent of processor 210.

The SIM card interface 295 is for interfacing with a SIM card. The SIM card may be inserted into the SIM card interface 295 or removed from the SIM card interface 295 to enable contact and separation from the electronic device. When the electronic device is a first device, the first device may support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 295 may support Nano SIM cards, micro SIM cards, and the like. The same SIM card interface 295 may be used to insert multiple cards simultaneously. The types of the plurality of cards may be the same or different. The SIM card interface 295 may also be compatible with different types of SIM cards. The SIM card interface 295 may also be compatible with external memory cards. The electronic equipment interacts with the network through the SIM card, so that the functions of communication, data communication and the like are realized. In some embodiments, the electronic device employs esims, namely: an embedded SIM card. The eSIM card can be embedded in the electronic device and cannot be separated from the electronic device.

In addition, the electronic device also runs an operating system on the components. Such as an iOS operating system, an Android operating system, or a Windows operating system, etc. An operating application may be installed on the operating system.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be implemented independently or combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

In this embodiment of the present application, the first device may be located in a scenario where the cellular network signal is weak or no cellular network signal is present (for example, one SIM card SIM1 in the first device is weak in the current scenario), and the second device may be located in a scenario where the cellular network signal is strong, where the first device and the second device may implement a method for connecting cellular communication capability described in the embodiments of the present application based on the embodiment corresponding to fig. 4 below. Fig. 4 is a schematic flow chart of a method for implementing cellular communication capability connection according to an embodiment of the present application.

The first device and the second device may log into the same device account (which may also be referred to as a user account) before the first device and the second device perform the method of continuing the cellular communication capability.

In a possible implementation manner, the first device and the second device may each be registered to the communication service cloud based on the device account number, the first device and the second device each have a surfing condition, the first device may include at least one SIM card, and/or the second device may include at least one free SIM card slot.

The communication service cloud has one or more of the following functions, for example: for device authentication of devices connected to the communication service cloud, for determining whether a device has a cellular communication capability continuation function (or may also be referred to as a device signal relay function, etc.), for determining whether a device has a free card slot, for determining whether a device has been connected to the communication service cloud, or for establishing a data forwarding channel between devices, etc. The first device and the second device are both registered to the communication service cloud based on the device account number, which can be understood as follows: the first device is logged into the communication service cloud based on the device account number and the password, and the second device is also logged into the communication service cloud based on the device account number and the password.

Wherein, the first device and the second device both have the internet surfing condition can be understood as: the first equipment and the second equipment can be connected to the network side in a wired mode; or the first device and the second device may also be connected to the network side through WIFI, a hotspot, or another SIM card SIM2 with a cellular network signal in the first device (for example, the cellular network signal of the current SIM2 is better than the cellular network signal of the current SIM 1), which is not limited in this embodiment of the present application.

It can be understood that, in the far-field connection scenario, the first device and the second device may both be connected to the communication service cloud through WIFI hotspots near each other, or the first device may be connected to the communication service cloud through another SIM card with a cellular network signal in the first device, and a trusted connection channel between the two devices is established based on the communication service cloud; or in the near field connection scenario, the first device and the second device may establish communication connection between the two devices by being connected to the same WIFI or the like, and in this embodiment, the device connection manner during near field connection or far field connection is not specifically limited.

As shown in fig. 4, the method for continuing the cellular communication capability may include the following steps:

S401, under the condition that the first equipment and the second equipment both start the cellular communication capability connection function, the first equipment and the second equipment establish communication connection.

The cellular communication capability connection function can be understood as: in the scene that the first device detects that the network signal is weak or no network signal, the second device with better network signal is utilized to connect the first device with the cellular communication capability, so that the first device can execute any cellular communication function in the scene that the network signal is poor by using the SIM card in the first device and the modem of the second device.

It may be appreciated that, in the embodiments of the present application, the data interaction between the plurality of first devices and the second device is implemented when the first device establishes a communication connection with the second device.

S402, the second device and the first device transfer the modem of the second device to the first device for use by utilizing the remote modem function.

In the embodiment of the present application, the remote modem function may be understood as: the a device may utilize a remote modem function to remotely access the modem of the B device.

In the step shown in S402, the a device may be a first device and the B device may be a second device, for example, the first device may remotely access a modem of the second device having cellular communication capability, so that the first device may share the modem of the second device and use the cellular communication function normally with the modem of the second device; or it is also understood that the modem of the second device may implement the overall migration, and that the modem of the second device may act as a virtual modem of the first device. The specific implementation of the remote modem function may refer to the corresponding embodiment of fig. 6.

For example, when the first device detects that the network signal is weak, no network signal is detected, or the first device receives a trigger operation of a user, the first device may initiate a relay mode switching instruction to the second device, where the relay mode switching instruction is used to instruct the second device to connect to the cellular communication capability of the first device. The second device may return, after receiving the relay mode switching instruction, a response message corresponding to the relay mode switching instruction to the first device, where the response message corresponding to the relay mode switching instruction is used to instruct the second device to agree to provide the first device with a connection of the cellular communication capability. After receiving the response message corresponding to the relay mode switching instruction, the first device may initiate an instruction (or referred to as a remote modem switching instruction) for remotely accessing the modem of the second device to the second device, so as to request to access the modem of the second device. Further, when the second device receives the remote modem switching instruction, a remote modem switching success instruction may be sent to the first device, and then the step shown in S403 may be executed.

Wherein, the description related to the relay mode switching instruction may refer to the step shown in S502 in the embodiment corresponding to fig. 5; the description related to the response message corresponding to the relay mode switching instruction may refer to the step shown in S503 in the embodiment corresponding to fig. 5; the description related to the remote modem switching instruction may refer to the step shown in S504 in the corresponding embodiment of fig. 5; the description related to the remote modem switch success instruction may refer to the steps shown in S506 in the corresponding embodiment of fig. 5.

S403, the first device and the second device remotely transfer the SIM card of the first device to the second device for use by utilizing a remote (remote) SIM function, so that the modem of the second device accesses the SIM card of the first device.

In this embodiment, the remote SIM function may be understood as: the a device may utilize a remote SIM function to remotely access the SIM card of the B device.

In the step shown in S403, the a device may be the second device and the B device may be the first device, for example, the SIM card of the first device may be remotely transferred to the second device for use, so that the second device remotely accesses the SIM card of the first device, and simulates a scenario in which the SIM card in the first device is pulled out and inserted into the second device for use. The implementation of the remote SIM function may be referred to in the corresponding embodiment of fig. 7.

For example, after sending a remote modem switch success instruction to the first device, the second device may continue to initiate an instruction to the first device to remotely access the SIM card of the first device (or referred to as a remote SIM switch instruction) requesting access to the SIM of the first device, so that the first device may send its own SIM card information to the second device, which may then register the cellular network with the SIM card information. After the second device registers with the cellular network using the SIM card information of the first device, the network resident information may also be returned to the first device. The SIM card information of the first device may be SIM card information of one of the SIM cards in the first device.

Wherein, the description related to the remote SIM switching instruction can refer to the step shown in S507 in the corresponding embodiment of fig. 5; the transferring and using process of the SIM card information can refer to steps S511-S513 in the corresponding embodiment of fig. 5; the description related to the resident information may refer to steps shown in S515 to S516 in the corresponding embodiment of fig. 5.

In a possible implementation manner, S404, the first device and the second device implement a Circuit Switched (CS) call service.

The CS call service may include: a CS calling session service, which may be understood as a session service initiated by the first device, and a CS called session service, which may be understood as a session service answered by the first device.

Illustratively, when the first device receives the CS caller call service, the first device may remotely forward the CS caller call service to the second device, and the modem of the second device may continue to send the CS caller call service to the device that needs to be called (or may be understood as a third device). Or when the modem of the second device receives the CS called call service, the second device can send the received CS called call service to the first device, so that the first device can display a telephone answering interface corresponding to the CS called call service. In the process that the first device and the second device implement the CS call service, the first device and the second device may implement answering and sending of the voice based on the step shown in S406.

In a possible implementation manner, the first device and the second device may also implement processing and forwarding of services related to IMS, such as IMS call services, based on the steps shown in S405.

It will be appreciated that the CS call service may be implemented based on the remote modem function and the remote SIM function, so that the first device and the second device may implement connection of the CS call service based on the steps shown in S401-S404 and S407.

S405, the first device and the second device transfer the IMS communication capability of the second device to the first device for use by utilizing a remote IMS function.

In this embodiment of the present application, the remote IMS function may be understood as: device a may utilize the remote IMS functionality to remotely use the IMS communication capabilities of device B.

In the step shown in S404, the a device may be a first device and the B device may be a second device, for example, the first device remotely uses IMS communication capabilities of the second device, so that the first device may implement IMS services using the IMS communication capabilities of the second device. The specific implementation of the remote IMS function may refer to an embodiment corresponding to fig. 8, and the IMS service may include: IMS call services and/or IMS SMS services, etc.

Illustratively, the IMS communication capability of the second device is obtained. For example, the first device may initiate an instruction (or referred to as a remote IMS handover instruction) to the second device for remotely accessing the IMS communication capability of the second device, such that the second device may return IMS registration information, service status, etc. messages to the first device via the remote IMS handover success instruction, etc.

Wherein, the description related to the remote IMS handover command may refer to steps shown in S512-S522 in the corresponding embodiment of fig. 5; the description of acquiring IMS registration information may refer to the step shown in S523 in the corresponding embodiment of fig. 5; the description related to the remote IMS handover success instruction may refer to the steps shown in S524 in the corresponding embodiment of fig. 5.

In a possible implementation manner, S406, the first device and the second device implement an IMS call service.

The IMS call service may include an IMS caller call and an IMS callee call.

For example, in the case where the first device allows use of the remote IMS communication capability of the second device, when the first device receives the IMS caller telephony service, the first device may remotely forward the IMS caller telephony service to the second device and continue to send the IMS caller telephony service to the third device of the call by the modem of the second device; or when the modem of the second device receives the IMS called call service, the second device can send the received IMS called call service to the first device, so that the first device can display a telephone answering interface corresponding to the IMS called call service.

In the process that the first device and the second device implement IMS call service, the first device and the second device may implement voice answering and sending based on the steps shown in S407.

S407, the second device forwards the network voice packet received by the modem from the network side to the first device, and the first device forwards the received local voice packet to the modem of the second device, and the modem reports the local voice packet to the network side.

In an exemplary case where the first device establishes an IMS call service (or a CS call service) with the second device, the second device may implement forwarding a network voice packet received by the modem of the second device from the network side to the first device, and the first device may also forward a local voice packet received based on a microphone of the first device to the modem of the second device, and report the local voice packet to the network side by the modem of the second device. Wherein the network voice packet may be understood as a voice packet received by the modem of the second device from the network side, or may be understood as a voice packet generated by the third device; the local voice packet may be understood as a voice packet collected locally by the first device.

It is understood that the IMS call service can be implemented based on the remote modem function, the remote SIM function, and the remote IMS function, so that the first device and the second device can implement connection of the IMS call service based on the steps shown in S401-S403 and S405-S407.

Based on this, the first device can utilize the second device to implement a continuation of the cellular communication capability in a scenario where the cellular network signal is weak.

It will be appreciated that the order of the steps described in the embodiment corresponding to fig. 4 is only an example, and the order of the steps may be adjusted, for example, may be performed sequentially or in parallel.

In some possible implementations, the first device and the second device may perform the remote modem function in the step shown in S402 before performing the remote SIM function in the step shown in S403; alternatively, the first device and the second device may execute the remote SIM function in the step shown in S403 first, then execute the remote modem function in the step shown in S402, and so on.

For example, in the case where the first device and the second device execute the remote SIM function in the step shown in S403 first and then execute the remote modem function in the step shown in S402, since the second device has a long process of reading the SIM card data of the first device during the remote SIM function, the first device always presents a card-free state on the screen of the first device during the remote SIM function, so that it is difficult for the user of the first device to determine the transfer condition of the SIM card according to the card-free state presented by the first device all the time (which may cause trouble and misunderstanding to the user, for example, the user may misuse the SIM card for a problem or misuse the "device signal relay" (or referred to as "cellular communication capability connection" or the like) function does not normally operate), and the first device presents a card-free state on the screen of the first device only after the remote SIM function and the remote modem function are executed.

It was found that the speed of remote access of the modem in the remote modem function was faster than the speed of remote access of the SIM in the remote SIM function. Therefore, when the first device and the second device first execute the remote modem function in the step shown in S402, and further execute the remote SIM function, various state changes of the second device can be transmitted to the first device at any time through the remote modem function. Therefore, in the process of the remote SIM function, the screen of the first equipment can be switched from the card-free state to the card-equipped state, and then the card-free state is switched to the service-equipped state, so that a user of the first equipment can conveniently and timely detect the change of the SIM card state in the process of continuing the cellular communication capability.

For example, when the first device and the second device first perform the remote SIM function in the step shown in S403, the SIM card triggers the input of the personal identification code (personal identification number, PIN), and then an indication message for inputting the PIN code may be displayed in the second device, but since the remote modem function is not performed yet, the information displayed in the second device cannot be transmitted to the first device through the remote modem function, so that the indication message for inputting the PIN code is not displayed in the first device, and therefore, the user of the first device cannot unlock the SIM card through inputting the PIN code, so that the second device cannot normally access the SIM card of the first device, and the entire cellular communication capability connection cannot continue.

And when the first device and the second device execute the remote modem function in the step shown in S402 first, and further execute the remote SIM function, and when the SIM card triggers the PIN code input, the indication message for inputting the PIN code may be forwarded to the first device through the remote modem function, so that the first device may display the indication message for inputting the PIN code in the interface, so that the user may conveniently input the PIN code in time to unlock the SIM card, and further facilitate the second device to normally access the SIM card of the first device to implement the cellular communication capability connection function.

As shown in fig. 6, the layered architecture of the first device divides the software into several layers, each with a clear role and division. The layers communicate with each other through a software interface. In some embodiments, the Android system is from top to bottom: an application layer, an application framework layer, and a system library. A modem may also be included in the first device.

The application layer may include a series of application packages. As shown in fig. 6, the application package may include: telephone, navigation, bluetooth, short message, etc.

The application framework layer includes a number of predefined functions. In a possible implementation manner, the application framework layer may further include: distributed communication service modules, telephony manager 6016 (telephony), etc.

The distributed cellular communication control module may be understood as a total control module in the distributed communication service module for determining a calling manner of different modules in the distributed communication service module based on different distributed communication services.

The remote modem service module 6011 is configured to forward the remote modem switching instruction to the remote modem service module 6011 of the second device, or may also forward a response message corresponding to the remote modem switching instruction, for example, a remote modem switching success instruction, network resident information, and other data to the phone manager 6016 of the first device.

In connection with the embodiment corresponding to fig. 6, after the first device initiates the relay mode switching instruction to the second device, the second device may return a response message corresponding to the relay mode switching instruction to the first device. Specifically, the distributed cellular communication control module of the first device may determine to initiate a relay mode switching instruction to the second device, e.g., the distributed communication service module of the first device may send the relay mode switching instruction to the distributed communication service module of the second device using the distributed bus 6012 of the first device and the distributed bus 6013 of the second device. The response message corresponding to the relay mode switching instruction may be used to instruct the second device to receive the relay mode switching instruction.

In a possible implementation manner, the distributed communication service module of the second device may also return a response message corresponding to the relay mode switching instruction to the distributed communication service module of the first device. Further, the second device and the first device may cause the first device to remotely access the modem of the second device based on the steps shown in S6001-S6008.

S6001, the remote modem service module 6011 of the first device sends a remote modem switching instruction to the remote modem service module 6014 of the second device using the distributed bus 6012 and the distributed bus 6013.

S6002, the remote modem service module 6014 sends the remote modem switch instruction to the RIL.

Adapted, modem6015 may receive the modem switching instruction sent by the RIL and generate a response message corresponding to the remote modem switching instruction, where the response message corresponding to the remote modem switching instruction may be: a remote modem switch success instruction for instructing the second device to allow the first device to remotely access the modem.

S6004, modem6015 sends a remote modem switch success instruction to RIL.

S6005, RIL sends a remote modem switching success instruction to remote modem service module 6014.

S6006 the remote modem service module 6014 transmits the remote modem switching success instruction to the remote modem service module 6011 of the first device using the distributed bus 6013 and the distributed bus 6012.

S6007, the remote modem service module 6011 transmits the remote modem switching success instruction to the telephone manager 6016.

Further, the application layer may display, in the first device, a network state corresponding to the second device, a card-free state corresponding to the second device, and the like, based on the remote modem switching success instruction.

In a possible implementation manner, in the case that the application layer of the first device receives a command of successful remote modem switching, when the first device needs to access the modem of the second device, the application layer of the first device may issue a corresponding request for cellular communication service to the phone manager 6016, so that the request for cellular communication service may be sent by the phone manager 6016 of the first device to the remote modem service module 6011 of the first device; further, the first device transmits the request for the cellular communication service to the modem6015 of the second device based on the steps shown in S6001 to S6003. Suitably, modem6015 of the second device may generate a response message corresponding to the request for the cellular communication service, and return the response message corresponding to the request for the cellular communication service to the application layer of the first device based on the steps shown in S6004-S6008.

The request of the cellular communication service is a request for requesting to execute a cellular communication service function related to an application, for example, a short message sending request triggered by a short message application, a telephone dialing request triggered by a telephone application, a telephone answering request and the like. The response message corresponding to the request of the cellular communication service is processing result data after the Modem processes the request of the cellular communication service, for example, if the request of the cellular communication service is a short message sending request, the response message corresponding to the request of the cellular communication service may be a specific reason for explaining whether the short message is sent successfully or not, and the short message is sent failed, etc.

It will be appreciated that the remote modem service module 6011 of the first device may implement that the request for the cellular communication service received by the phone manager 6016 of the first device is not transmitted to the modem of the first device through the interface any more by creating a proxy object of the interface, but forwards the request for the cellular communication service to the remote modem service module 6014 of the second device through the proxy object of the interface. Further, the remote modem service module 6014 of the second device can send a request for cellular communication services to the modem6015 of the second device for processing to assist the first device in using cellular communication capabilities. The adapted remote modem service module 6014 of the second device creates a proxy object of the interface for forwarding a response message corresponding to the request for cellular communication service to the remote modem service module 6011 of the first device.

Remote SIM access interface adaptation module: may be used to adapt the remote SIM access, and control interface of the RIL modules of different chip manufacturers. It will be appreciated that different chip vendors may define different rssim HIDL interfaces 7104, and the data structures carrying the messages may also be different, so that the remote SIM access interface adaptation module may implement remote SIM switching instructions (or remote SIM requests, etc.), and normal invocation of SIM card information.

In a possible implementation, the remote SIM service module of the second device may also send a remote SIM switch instruction to the modem of the second device. The modem in the second device may be adapted to switch the SIM card mode to a remote client mode for instructing the second device not to read the SIM card information through the local SIM card slot, but to remotely read the SIM card information of the first device through an rsvi interface or the like.

S7003, the remote SIM RIL module 7105 sends a remote SIM switch instruction to the remote SIM card module 7107 in the modem through the rsvi interface 7106.

Adaptively, when the remote SIM card module 7107 receives a remote SIM switch instruction, the SIM card mode of the first device may be switched to a remote service module, where the remote service module is configured to instruct the first device to allow sharing of the SIM card of the first device to the second device. Further, the remote SIM card module 7107 may obtain SIM card information in the SIM hard card 7109 through the SIM card slot driver 7108, and send the obtained SIM card information to the modem of the second device through steps shown in S7004-S7008.

S7008, the remote SIM RIL module 7115 sends the SIM card information to the remote SIM card module 7113 in the modem through the rsvi interface 7114.

In a possible implementation, the SIM card module 7112 in the modem of the second device may register the cellular network with the SIM card information and return the resident network information to the modem of the first device based on the paths described in the steps shown in S7009-S7010 and the steps shown in S7001-S7003.

S7009, the modem of the second device sends the network resident information to the remote SIM RIL module 7115 through the rsvi interface 7114.

Further, the remote SIM service module 7102 of the second device may return the network resident information to the modem of the first device based on the paths described in the steps shown in S7001-S7003, which is not described in the embodiment of the present application.

It will be appreciated that in case the first device and the second device perform a remote SIM card switch based on the steps described in the corresponding embodiment of fig. 7, the second device may access the SIM card in the first device based on a remote SIM request, such as an Answer To Reset (ATR) request, an application protocol data unit (application protocol data unit, APDU) request, etc. The ATR request and APDU request may be sent to the modem of the first device based on the paths shown in S7009-S7010 and S7001-S7003.

In response, the first device may return a response message corresponding to the remote SIM request, such as an ATR response corresponding to the ATR request, an APDU response corresponding to the APDU request, and other data, to the modem of the second device through steps shown in S7004-S7008. The ATR request, ATR response, APDU request, and APDU result may be all requests or response manners commonly used in SIM card communication protocols, which are not described herein.

In the step shown in S404, based on the embodiment corresponding to fig. 4, the process of transferring the IMS communication capability of the second device to the first device based on the remote IMS function by the second device may be referred to the embodiment corresponding to fig. 8.

Fig. 8 is a schematic diagram of a system architecture for remotely using IMS functions according to an embodiment of the present application.

As shown in fig. 8, the layered architecture of the first device divides the software into several layers, each with a clear role and division. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an IMS APK, and a HAL layer, respectively. A modem may also be included in the first device.

The content included in the application layer may refer to the content in the application layer in the embodiment corresponding to fig. 6 (or fig. 7), which is not described herein.

The application framework layer may include a telephony manager and a distributed communication service module therein. Wherein, the telephone manager can comprise: an IMS telephony module, and an IMS management module (IMS manager). The IMS telephone module can be used for providing an interface to the outside; the IMS management module is used for providing an API which interacts with the IMS service module and managing IMS related functions; and the IMS management module may also be the caller of the IMS service module. The IMS management module may be understood as a module specified in the android system architecture.

The distributed service module may include: remote IMS service module 8101. The remote IMS service module 8101 may include: an IMS call session proxy (IMS call session proxy) module, and a SIM call session listening proxy (IMS call session listener proxy) module. The IMS call session proxy module of the first device may be configured to send a local remote IMS handover command (or IMS service request, etc.) to the IMS call session proxy module of the second device. The SIM call session monitoring proxy module of the first device is configured to return a remote IMS handover success instruction (or a response message corresponding to the IMS service request) sent by the second device to the IMS management module in the telephony manager.

The distributed service module may further include a distributed cellular communication control module, a distributed bus 8103, etc., and the functions of the distributed cellular communication control module and the distributed bus 8103 may be described in the corresponding embodiment of fig. 6 (or fig. 7), which is not described herein. The first device may further include: an IMS APK, which may include an IMS service module, wherein the IMS service module provides services related to IMS, and the IMS service module is used for interacting with a modem side or an audio side to realize functions related to IMS.

The HAL may include: audio HAL8105, and audio stream forwarding module 8106. The audio HAL8105 is configured to implement switching of a forwarding mode of audio data according to an instruction for indicating channel switching sent by the remote IMS service module, for example, the audio HAL may switch the forwarding mode of the audio data from a local mode to a remote mode. Further, the audio HAL8105 may send an instruction for indicating channel switching to the audio stream forwarding module 8106, so that the audio stream forwarding module 8106 may switch a transmission channel of audio data, thereby implementing remote forwarding of the received voice packet to the second device.

In a possible implementation, the HAL of the second device may include: audio HAL8108, audio stream forwarding module 8107, and RIL, which may enable data forwarding between IMS service modules and modems. The function of the audio HAL8108 in the second device may be similar to that of the audio HAL8105 in the first device, and the function of the audio stream forwarding module 8107 in the second device may be similar to that of the audio stream forwarding module 8106 in the first device, which will not be described again.

The audio stream forwarding module 8106 may implement forwarding of voice packets. For example, the audio stream forwarding module 8107 in the second device may be configured to forward the speech packet received by the modem of the second device from the network side to the first device, so that the first device may play the speech packet sent by the second device based on the speaker. Alternatively, the audio stream forwarding module 8106 in the first device may be further configured to forward the voice packet received based on the microphone to the modem of the second device, and forward the voice packet to the network side by the modem of the second device.

In a possible implementation manner, the HAL of the first device may also include RIL, which may be used to implement data forwarding between the IMS service module of the first device and the modem of the first device. Wherein, RIL may be included in the RIL.

A SIM hard card can be connected in a modem of the first device; the modem of the second device may or may not be connected to the SIM card.

It is understood that the software architecture of the second device is similar to that of the first device in the embodiment corresponding to fig. 8, and functions in the software architecture may be similar to those described in the embodiment corresponding to fig. 8, and will not be described herein.

It will be appreciated that the distributed cellular communication control module of the first device may determine to send a remote IMS handover instruction to the second device, e.g. the distributed cellular communication control module of the first device may instruct the remote IMS service module 8101 to send a remote IMS handover instruction to the remote SIM service module 8102 of the second device.

S8001, the IMS call session proxy module in the remote IMS service module 8101 of the first device sends a remote IMS handover command to the IMS call session proxy module in the remote IMS service module 8102 of the second device.

Illustratively, the IMS call session proxy module in the remote IMS service module 8101 sends the remote IMS handover instruction to the IMS call session proxy module of the second device based on the distributed bus 8103 of the first device and the distributed bus 8104 of the second device.

In this embodiment of the present application, the first device may create a proxy object of the interface in the IMS management module, for example, create a proxy object of the IMS call session proxy module, so that the IMS management module will not forward the received request of the remote IMS handover command to the local IMS service module, but forward the request to the second device via the IMS call session proxy module.

S8002, the IMS call session proxy module of the second device sends the remote IMS switch instruction to an IMS management module in the telephone manager.

S8003, the IMS management module sends the remote IMS switch instruction to the IMS service module.

S8004, the IMS service module sends the remote IMS switch instruction to a modem of the second device.

In a possible implementation, the IMS service module may send a remote IMS handover command to the RIL, and the RIL continues to send the remote IMS handover command to the modem of the second device.

When receiving the remote IMS switch instruction, the modem can acquire IMS registration information and return a remote IMS switch success instruction with the IMS registration information to the first device. The IMS registration information enables the first device to support call functions such as long term evolution voice bearer (voice over long term evolution, VOLTE) or new air interface bearer voice (voice over new radio, VONR).

S8005, the modem of the second device sends a remote IMS switch success instruction to the IMS service module.

In a possible implementation manner, the modem of the second device sends the remote IMS handover success instruction to the RIL, and the RIL continues to send the remote IMS handover success instruction to the IMS service module.

S8006, the IMS service module sends a remote IMS switching success instruction to an IMS management module in the telephone manager.

S8007, the IMS management module sends the successful instruction of the remote IMS switch to an IMS call session monitoring proxy module in the remote IMS service module 8102.

It will be appreciated that the IMS management module may create a proxy object for the IMS call session listening proxy module such that the IMS management module does not forward the received request for a remote IMS handover success instruction to the local IMS telephony module, but rather to the first device via the IMS call session listening proxy module.

S8008, the IMS call session monitoring proxy module of the second device sends a remote IMS switching success instruction to the IMS call session monitoring proxy module of the first device.

Specifically, the IMS call session monitoring agent module of the second device may send a remote IMS handover success instruction to the IMS call session monitoring agent module of the first device using the distributed bus 8104 of the second device and the distributed bus 8103 of the first device.

In a possible implementation, the IMS call listening agent may return a remote IMS handover success instruction to the application layer of the first device based on the steps shown in S8009-S8011.

It can be appreciated that, since there are a lot of frequent IMS call session method invocations for querying current state information during the processing of IMS services, such as querying a call identifier (getCallId), querying a call state (getState), querying a multiparty conference message (multiparty), etc. Therefore, in consideration of network overhead and instantaneity, the call requests of all the first devices are not directly forwarded to the second device call, but a local caching mode is adopted: the second device can actively synchronize its own state to the first device and store the state in a local cache module of the first device; when the first device needs to query the current state, the IMS call session proxy module may directly obtain data from the local cache module.

It can be appreciated that at this time, part of the interfaces in the IMS call session proxy module may be changed from the synchronous call mechanism to the notification caching mechanism. The local buffer module may be disposed in the remote IMS service module, or may be disposed at another location, which is not limited in the embodiment of the present application.

S8009, the IMS call session monitoring proxy module of the first device sends a remote IMS switching success instruction to an IMS management module.

And S8010, the IMS management module sends a remote IMS switching success instruction to the IMS telephone module.

And S8011, the IMS telephone module sends a remote IMS switching success instruction to an application layer of the first equipment.

When the application layer of the first device receives IMS registration information in an IMS handover success instruction from the second device, the first device may display a High Definition (HD) identifier in a status column of the interface, where the HD identifier is used to instruct the first device to start a high definition voice call function.

In a possible implementation manner, in a case that the first device is provided with the IMS communication capability of the second device based on the steps shown in S8001-S8011, the first device may complete any IMS service based on the data interaction with the second device.

The IMS service is exemplified as an IMS call service. For example, when the application layer of the first device receives the IMS call service request, the application layer of the first device may send the calling service request to an IMS phone module in the phone manager of the first device, and the IMS phone module sends the calling service request to the IMS management module, which sends the IMS service request to the IMS call session proxy module of the first device in proxy mode, and further forwards the calling service request to the modem of the second device by the first device based on the path described in the steps shown in S8001-S8004. The second device may send a response message corresponding to the calling service request to the application layer of the first device based on the steps shown in S8005-S8011. The response message corresponding to the IMS call service request is used for indicating the second equipment to allow the first equipment to execute the IMS call service.

Further, the first device may send the locally generated voice packet to the modem of the second device through the audio stream forwarding module 8106 of the first device and the audio stream forwarding module 8107 of the second device, where the modem of the second device sends the voice packet to the network side. Alternatively, the modem of the second device may return the voice packet received from the network side to the first device through the audio stream forwarding module 8107 of the second device and the audio stream forwarding module 8106 of the first device. The first equipment can complete connection of the call in the IMS service by using the second equipment.

It can be appreciated that since the 3GPP supports two ways of providing call services at present, namely CS domain call and Packet Switched (PS) domain call. The IMS domain call may be a call mode commonly used in PS domain call.

For CS domain calls, a software implementation of CS domain calls may refer to the corresponding embodiment of fig. 9. Fig. 9 is a schematic flow chart of a CS domain call according to an embodiment of the present application.

As shown in fig. 9, the CS domain call flow may involve a telephony application, a telephony manager, a RILD, and a modem. Wherein the phone application and phone manager can be understood as a chip-independent software module common to android platforms; RILD and modem are understood to be software modules associated with a chip. Wherein the software module related to the chip can be understood as a module provided by a manufacturer of the chip or as a module related to the chip which can only run in the chip provided by the corresponding manufacturer of the chip; the chip independent software module is an android platform native software module that can run on any chip vendor supplied chip.

It will be appreciated that referring to the CS call flow corresponding to fig. 9 and the remote modem function corresponding to fig. 6, the telephny needs to interact with the RILD through a standard IRadio HIDL/AIDL interface. Therefore, the CS call service can be realized based on the data transmission flow corresponding to the remote modem function.

For IMS domain calls, a software implementation of IMS domain calls may be referred to the corresponding embodiment of fig. 10. Fig. 10 is a schematic flow chart of IMS domain call according to an embodiment of the present application.

As shown in fig. 10, the IMS domain call flow may involve a telephony application, a telephony manager, an IMS APK, a RILD, and a modem. Wherein the phone application and phone manager can be understood as a chip-independent software module common to android platforms; the IMS APK, RILD and modem can be understood as software modules related to the chip.

It can be understood that referring to the IMS call flow corresponding to fig. 10, only the interface in the application framework layer is defined in the android software architecture, and the HIDL/android interface definition language (android interface definition language, AIDL) interface interacting with the RILD in the IMS call is implemented depending on the IMS APK of the respective chip manufacturer, and has no uniform interface definition, so that the message forwarding of the IMS service cannot be implemented by the proxy HIDL interface/AIDL interface. For example, the chip manufacturer 1 needs to use the IMS APK provided by the chip manufacturer 1, and the chip manufacturer 1 cannot use other IMS APKs provided by the chip manufacturer 1.

Thus, the proxy access point for the remote IMS function may be moved up to the IMS management module in the telephony manager so that IMS traffic may be forwarded to the remote IMS service module through the proxy of the IMS management module. The specific process of the IMS management module when performing proxy may refer to the embodiment corresponding to fig. 8, which is not described herein.

Based on the method, the first device can utilize the second device to realize connection of multiple services such as CS call service, IMS call service and the like, enrich the use scope of the connection method of the cellular communication capability, and further improve the use experience of the user on the device.

The procedure of starting the cellular communication capability continuing function by the first device or the second device in S401 on the basis of the above-described embodiment corresponding to fig. 4 may refer to the embodiment corresponding to fig. 11 or fig. 12.

In this embodiment of the present application, the first device may support starting the cellular communication capability connection function from the interface corresponding to the SIM card management function (see the embodiment corresponding to fig. 11), or the first device may support starting the cellular communication capability connection function from the interface corresponding to the more connection functions used to set the first device (see the embodiment corresponding to fig. 12). It will be appreciated that the specific manner of starting the cellular communication capability continuing function is not limited to the two above, and this is not a limitation in the embodiments of the present application.

In one implementation, a first device supports enabling a cellular communication capability continuation function from an interface corresponding to a SIM card management function.

Fig. 11 is an interface schematic diagram of a function of starting a cellular communication capability according to an embodiment of the present application. In the embodiment corresponding to fig. 11, the method for starting the cellular communication capability connection function by the first device and taking the first device as a mobile phone is illustrated by taking the first device as an example, and the method for starting the cellular communication capability connection function by the second device may refer to the description in the embodiment corresponding to fig. 11, which will not be described in detail.

Wherein the card 1 may correspond to a phone number of 1234567XXXX, the card 1 may provide the first device with a 5G/4G/3G/2G network under XX mobile vendor; the card 2 may correspond to a 1324567XXXX cell phone number, the card 2 may provide the first device with a 5G/4G/3G/2G network under XX Mobile vendor, and the default movement data may correspond to card 1 or card 2.

In a possible implementation manner, the control 1103 for setting the device signal relay may also be set in an interface where the mobile network function is located as shown in b in fig. 11, which is not limited in this embodiment of the present application.

In the interface shown as c in fig. 11, when the first device receives a trigger operation of the user for the control 1103 for setting the device signal relay, the first device may display the interface shown as d in fig. 11. The interface shown as d in fig. 11 may include: a control 1104 for turning on or off the device signal relay, a control for exiting the device signal relay, indication information for indicating that the device is performing a cellular communication capability continuation function, and indication information for indicating a condition that needs to be met by the triggering device signal relay. Wherein, the indication information for indicating the device cellular communication capability connection function can be displayed as: under the condition that no cellular network signal exists in a basement and the like, communicating and receiving short messages are carried out by utilizing the cellular networks of other idle equipment; the indication information for indicating the condition that the signal relay of the trigger device needs to meet may be displayed as: the trigger device signal relay needs to meet the following conditions: 1. the user has a plurality of mobile phones/tablets and logs in the equipment account; 2. the equipment is opened with a signal relay switch; 3. other devices for relay require a free slot. Wherein the signal relay switch may be a control 1104 shown as d in fig. 11 for turning on or off the device signal relay; one or more spare slots may be included in the other device for relaying, or there may be no spare slots in the other device for relaying, which is not limited in this embodiment of the present application.

In a possible implementation manner, the indication information for indicating the device cellular communication capability connection function in the interface shown in d in fig. 11 may further include one or more of the following, for example: the device does not have signals of the cellular network, and the device needs to be connected with WI-FI and the like, which is not limited in the embodiment of the application.

In the interface shown in d in fig. 11, when the first device receives a trigger operation of a user for opening or closing the control 1104 for device signal relay in the state that the device cellular communication capability connection function is closed, the first device may open the device cellular communication capability connection function and register in the communication service cloud by using the device account number.

In another implementation, the first device supports turning on a cellular communication capability continuation function from an interface for setting up more connection functions of the first device.

Fig. 12 is a schematic diagram of another interface for turning on a connection function of a cellular communication capability according to an embodiment of the present application.

The first device displays an interface as shown in a in fig. 12, which may include: the content displayed in this interface for setting up more connected controls 1201 may be similar to that shown in a of fig. 11 and will not be described again here.

The content displayed in the interface shown in c in fig. 12 is similar to that in the interface shown in d in fig. 11, and will not be described again.
