Description

Technical Field

[0001] The present subject matter generally relates to facilitating multiple telephone calls, and more particularly to a method and system for facilitating multiple telephone calls in an electronic device. Background Art

[0002] Traditionally, when a user equipment (UE) is in standby mode, there is no active uplink or downlink communication. The UE is just listening on the paging channel. In response to a paging or if there is some uplink information to send, the UE can change from standby mode to active mode.

[0003] In a single radio multi-SIM device such as a dual SIM dual standby (DSDS) device, if the user makes a call on SIM 1, the radio becomes unavailable for SIM 2 (SIM 2 standby mode), so calls on SIM 2 are not received on the mobile phone. Thus, it is not possible to receive (MT) and interact with (listen to / text) a SIM 2 call while a SIM 1 call is in progress. Further, if the user makes a call on SIM 1, the radio becomes unavailable for SIM 2 (SIM 2 standby mode), so any outgoing communication (MO) from SIM 2 is not possible, and thus it is not possible to interact with a SIM 2 call while a SIM 1 call is in progress.

[0004] In addition, the problem arises because DSDS smartphones have a single radio which can handle all communications of only one SIM at a time, and traditionally since the user would only listen to / talk to one user, the mobile phone would handle one call at a time.

[0005] Traditional solutions disclose a method for enabling simultaneous calls on two SIMs in a dual SIM dual-active (DSDA) device in a dual SIM dual-RF scenario. A call on SIM 1 arrives on a first RF and a call on SIM 2 arrives on a second RF, and then using a text engine, one of the calls is routed to the engine and answered using text. The prior art is defined for a DSDA chipset (a device with dual RFs to latch two SIMs simultaneously) to provide simultaneous access to two calls, and this traditional solution cannot be achieved with a single RF.

[0006] Another conventional solution discloses a method of using the network of a primary SIM card to access the services of a secondary SIM card. The secondary SIM card (SIM 2) uses the network of the primary SIM card (SIM 1) to register with a secondary server to allow access to SIM 2 services. The user can receive calls / texts of the secondary SIM card when the secondary SIM has no service using the primary SIM card data connection. Another conventional solution allows the user to interact with the service on the secondary SIM when the secondary SIM has no service, without providing interaction with two calls received using the primary SIM and the secondary SIM when the secondary SIM is registered on the primary network.

[0007] A solution is needed to overcome the above disadvantages. Summary of the Invention

[0050] In an example, memory 206 can include any non-transitory computer-readable medium known in the art, including, for example, volatile memory (such as static random access memory (SRAM) and / or dynamic random access memory (DRAM)) and / or non-volatile memory (such as read-only memory (ROM), erasable programmable ROM (EPROM), flash memory, hard disks, optical disks, and / or magnetic tapes). Memory 206 can include data 208.

[0056] Continuing with the above embodiment, the detection engine 214 may be configured to detect the initiation of a first phone call in the electronic device. The first phone call may be for the first SIM. In addition, the first phone call may be initiated via one of a first SIM network associated with the first SIM and a second SIM network associated with the second SIM. Initiating the first phone call may indicate activation of the first phone call, and the first phone call may be initiated from or received at the electronic device.

[0057] Continuing with the above embodiment, the detection engine 214 may be configured to detect either the dialing or the receiving of a second phone call in the electronic device. The second call may be for the second SIM. In addition, the second phone call may be dialed from or received at the electronic device via one of the first SIM network and the second SIM network. The second phone call may be dialed or received while the first phone call is active, such that the first phone call and the second phone call are both active. In addition, the second phone call may be initiated via one of the second SIM network associated with the second SIM and the second SIM network associated with the second SIM.

[0058] Next, the detection engine 214 may be configured to detect that one of the first SIM and the second SIM is changed to the standby mode. The one SIM may be associated with a network service, and the network service for the one SIM may be unavailable. The detection may be performed in response to initiating a first phone call via the other SIM of the first SIM and the second SIM.

[0059] Continuing with the above embodiment, the detection engine 214 may be configured to determine whether another network service associated with the other SIM is available. In addition, the registration engine 220 may be configured to register the one SIM in the standby mode on the other network service associated with the other SIM to activate the one SIM on the evolved packet data gateway (ePDG) of the other SIM. The registration of the one SIM may be performed in response to determining that the other network service associated with the other SIM is available.

[0060] In response to the detection engine 214 detecting that the first phone call and the second phone call are simultaneously active, the option generation engine 216 can be configured to provide options to the user. The options can be used to select one of the first phone call and the second phone call for voice interaction. In response to providing the options, the option generation engine 216 can be configured to receive a command from the user that indicates selection of one of the first phone call and the second phone call for voice interaction. In an embodiment, the user can select the first phone call for voice interaction.

[0061] In another embodiment, the user can select the second phone call for voice interaction. The voice interaction can indicate that the one of the first phone call and the second phone call selected for voice interaction will continue as an audio call. Additionally, the option generation engine 216 can be configured to connect a call buffer associated with a call other than the one of the first phone call and the second phone call selected for voice interaction to the NLE. The call buffer can be used for the one of the first phone call and the second phone call not selected for voice interaction. Next, the option generation engine 216 can be configured to connect the microphone and speaker buffers to one or more call buffers associated with the one of the first phone call and the second phone call selected for voice interaction.

[0062] In accordance with this understanding, the activation engine 218 can be configured to activate the NLE incorporated in the system 202. In an embodiment, the NLE can be present within the activation engine 218. The NLE can be configured to process the one of the first phone call and the second phone call not selected for voice interaction. When the one of the first phone call and the second phone call selected for voice interaction is activated as an audio call via voice interaction, processing can be performed in a predefined transition mode. Next, to process one of the first phone call and the second phone call in the predefined transition mode, the NLE can be configured to receive a first text and incoming audio associated with the one of the first phone call and the second phone call being processed by the NLE. The first text can be generated by a user of the electronic device. Additionally, the incoming audio can be associated with another user of the one of the first phone call and the second phone call being processed by the NLE. In accordance with this understanding, the NLE can be configured to convert the first text to speech and convert the incoming audio to a second text.

Figure 2B The embodiment of the electronic device 200 shown in FIG. 0 is for illustrative purposes only. Other embodiments of the electronic device 200 may be used without departing from the scope of the present disclosure.

[0064] In an embodiment of the present disclosure, the electronic device 200 may include at least one processor 204 and a memory 206. The processor 204 and the memory 206 may be communicatively coupled to each other.

[0065] In an embodiment of the present disclosure, the electronic device 200 may exclude at least one of these components, or may add at least one other component.

[0066] According to an embodiment of the present disclosure, the processor 204 may include one or more processors. At this time, the one or more processors may be a general-purpose processor (such as a central processing unit (CPU), an application processor (AP), etc.), a graphics processing unit only (such as a graphics processing unit (GPU), a vision processing unit (VPU)), and / or an AI dedicated processor (such as a neural processing unit (NPU)).

[0067] In an example, the processor 204 may be a single processing unit or multiple units, all of which may include multiple computing units. The processor 204 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, processor cores, multi-core processors, multi-processors, state machines, logic circuits, application-specific integrated circuits, field-programmable gate arrays, and / or any device that manipulates signals based on operation instructions. Among other capabilities, the processor 204 may be configured to obtain and / or execute computer-readable instructions and / or data stored in the memory 206.

[0068] In an embodiment of the present disclosure, the processor 204 may detect the initiation of a first telephone call among a plurality of telephone calls associated with a first subscriber identity module (SIM) in the electronic device, wherein the initiation of the first telephone call is via one of a first SIM network associated with the first SIM or a second SIM network associated with a second SIM. The processor 204 may detect the initiation of a second telephone call among the plurality of telephone calls associated with the second SIM, wherein the initiation of the second telephone call is via one of the first SIM network or the second SIM network. And the processor 204 may activate the natural language engine (NLE) to process another one of the first telephone call or the second telephone call in a predefined conversion mode while one of the first telephone call or the second telephone call is activated via voice interaction.

[0069] In an example, the memory 206 may include any non-transitory computer-readable medium known in the art, including, for example, volatile memory (such as static random access memory (SRAM) and / or dynamic random access memory (DRAM)) and / or non-volatile memory (such as read-only memory (ROM), erasable programmable ROM (EPROM), flash memory, hard disk, optical disk, and / or magnetic tape).

[0070] In an embodiment of the present disclosure, the memory 206 may store text received from a user of the electronic device and incoming audio received from another user of one of the first telephone call or the second telephone call being processed by the NLE.

[0071] Figure 3 An operation flowchart of a process 300 for facilitating a plurality of telephone calls according to an embodiment of the present disclosure is shown. In an embodiment, the process 300 may be implemented by the system 202 as mentioned in Figure 2A In an embodiment, the system 202 may be incorporated in an electronic device such as a single-radio multi-SIM device. A plurality of telephone calls may be conveniently executed simultaneously such that a user can initiate or receive two telephone calls at a time. The plurality of telephone calls may include a first telephone call and a second telephone call. The first telephone call and the second telephone call may be one of an audio call between two users and an audio conference call among at least three users.

[0072] In step S302, the process 300 may include detecting the initiation of a first telephone call in the electronic device. The detection may be performed by, for example, Figure 2AIt is executed by the detection engine 214 mentioned above. The first phone call can be directed to the first SIM and initiated via one of the first SIM network associated with the first SIM and the second SIM network associated with the second SIM. Initiating the first phone call can indicate that the first phone call is activated, and the first phone call can be initiated from or received at the electronic device.

[0073] In step S304, process 300 can include detecting either the dialing or receiving of a second phone call in the electronic device. The detection can be performed by the detection engine 214. Additionally, the second call can be directed to the second SIM and can be initiated from or received at the electronic device via one of the first SIM network and the second SIM network. The first phone call and the second phone call can be activated simultaneously. Moreover, the second phone call can be initiated via one of the first SIM network associated with the second SIM and the second SIM network associated with the second SIM.

[0074] In step S306, process 300 can include detecting by the detection engine 214 that one of the first SIM and the second SIM is changed to the standby mode. This detection can be performed in response to initiating the first phone call via the other one of the first SIM and the second SIM. The one SIM can be associated with the network service, and the network service for the one SIM may be unavailable.

[0075] In step S308, process 300 can include determining whether another network service associated with the other SIM is available. This determination can be performed by the detection engine 214. In an embodiment, in the case where it is determined that another network service associated with the other SIM is available, process 300 can include registering the one SIM in the standby mode on the other network service associated with the other SIM to activate the one SIM on the evolved packet data gateway (ePDG) of the other SIM.

[0076] In step S310, simultaneously with steps S304 and S306, process 300 can include providing options to the user by the option generation engine 216 as mentioned in Figure 2A Options can be provided to the user in response to detecting that the first phone call and the second phone call are activated simultaneously. The options can be used to select one of the first phone call and the second phone call for voice interaction. Additionally, process 300 can include receiving an input signal from the user indicating which one of the first phone call and the second phone call is selected for activation via voice interaction. The voice interaction can indicate that the one phone call selected for voice interaction among the first phone call and the second phone call will continue as an audio call.

[0077] In step S312, process 300 may include connecting, by option generation engine 216, a call buffer associated with a call other than the one of the first and second phone calls selected for voice interaction to the NLE. The call buffer may be used for the one of the first and second phone calls not selected for voice interaction. Additionally, process 300 may include connecting, by option generation engine 216, the microphone and speaker buffers to one or more call buffers associated with the one of the first and second phone calls selected for voice interaction.

[0078] In step S314, process 300 may include activating, by activation engine 218, the NLE to process the one of the first and second phone calls not selected for voice interaction. When the one of the first and second phone calls selected for voice interaction is an audio call via voice interaction activation pass-through, the processing may be performed in a predefined conversion mode. Next, to process one of the first and second phone calls in the predefined conversion mode, the NLE may be configured to receive a first text and incoming audio associated with the one of the first and second phone calls being processed by the NLE. The first text may be generated by a user of the electronic device.

[0079] Additionally, the incoming audio may be associated with another user of the one of the first and second phone calls being processed by the NLE. In accordance with this understanding, the NLE may be configured to convert the first text to speech and convert the incoming audio to a second text.

[0080] Figure 4 FIG. 400 is an architectural flowchart of an electronic device configured to facilitate multiple phone calls according to an embodiment of the present disclosure. The multiple phone calls may include a first phone call and a second phone call. Additionally, the electronic device may include a first SIM associated with a first network and a second SIM associated with a second network.

Additionally, the first phone call can be initiated via one of a first SIM network associated with the first SIM and a second SIM network associated with the second SIM. Initiating the first phone call can indicate the activation of the first phone call, and the first phone call can be initiated from or received at the electronic device. In an embodiment, the first phone call can be activated via the first SIM, and the second SIM can be in a standby mode (410). When the second SIM is in the standby mode, network services associated with the second SIM may not be available. In an embodiment, in the case of determining that the network services associated with the first SIM are available, the second SIM can be registered on the network services of the first SIM to activate the second SIM on the evolved packet data gateway (ePDG) of the first SIM (420).

[0082] Additionally, when a second phone call is made or received on the electronic device when the first phone call is activated, the natural language engine (NLE) (430) can be configured to activate a text-to-speech (TTS) converter for outgoing audio (MO) and a speech-to-text (STT) converter for incoming audio (MT) to maintain the round-trip communication of the second phone call on the second SIM in parallel with the first phone call on the first SIM, such that multiple phone calls can be facilitated. Additionally, a call buffer can be selected for the second phone call, and the microphone and speaker buffers can be connected to one or more call buffers associated with the first phone call for voice interaction. In the above embodiment, the first phone call can continue in the form of an audio call, while the second phone call can continue via the NLE (430) to facilitate multiple phone calls activated at a similar time in the electronic device.

[0087] In an embodiment, process 500b may include providing an option to the user by an option generation engine 216 as mentioned in Figure 2A The option may be used to select one of the first phone call and the second phone call for voice interaction. Further, a command indicating that one of the first phone call and the second phone call is selected for voice interaction may be received from the user. The voice interaction may indicate that one of the first phone call and the second phone call selected for voice interaction will continue as an audio call.

[0088] With this understanding, for one of the first and second phone calls selected for voice interaction, the microphone and speaker buffers can be connected to the call buffer, and the other call buffer can be connected to the natural language processing (NLP) engine. If the user needs to switch between the first and second phone calls, the buffer of the first call can be connected to the NLP engine, and the buffer of the second phone call can be connected to the microphone and speaker.
