Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second," and the like, in the description and in the claims of the embodiments of the present application are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first target object and the second target object, etc. are specific sequences for distinguishing different target objects, rather than describing target objects.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Voice over Internet Protocol (VoIP) is a Voice call technology, and a Voice call and a multimedia conference are achieved through Internet Protocol (IP), that is, communication is performed through the Internet. Other informal names are IP telephony, internet telephony, broadband telephony and broadband telephony services. The VoIP technology is a technology for converting voice into IP packets and transmitting the packets partially or entirely over an IP network.

In the embodiments of the present application, the term "carrier voice data" or "carrier voice signal" refers to data (or signal) in a network format supporting a carrier transmission network. And, "VOIP voice data" or "VOIP voice signal" each refer to data (or signals) in a network format that supports a VOIP transmission network.

In the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; the plurality of systems refers to two or more systems.

For example, as shown in fig. 1, an exemplary application scenario is shown, where a user a has a terminal B and a terminal C (for example, both are single-card handsets), the terminal B is used for communicating with a client, and the terminal C is used for life communications. In this scenario, the user a leaves the terminal B home, and when the client of the user a calls the user B (the Subscriber Identity Module (SIM) card number of the terminal B), the user a cannot receive the telephone of the client.

In the prior art, a call forwarding service is proposed, in which a user a can set a plurality of terminals to a call forwarding mode, for example, all the phones of the terminal C are forwarded to the terminal B, without carrying a plurality of terminals. However, the current call forwarding function incurs communication charges, and as the number of terminals owned by a user increases, the higher the charges required for call forwarding, the method is not suitable for use in a multi-device communication scenario. It should be noted that, in the present application, the SIM card number may also be referred to as an operator number, a terminal number, or a mobile phone number, and other terminals may initiate an operator voice call to the terminal based on the number.

In the prior art, a call reminding service is also provided, where a user a can set the call reminding service on a terminal B, and then incoming calls on the terminal B can be sent to a terminal C in an instant messaging manner, such as short message reminding, and the user can return calls to the incoming call user according to the reminding content. However, the service still generates unnecessary communication charges because all users change from called users to calling users, and secondly, the prompt mode of instant messaging may cause users not to receive or see notifications in time, and also important calls may be missed.

In view of the above problems, the present application provides a communication method, which can convert the operator voice call and the VOIP voice call of the terminal, so that the user can answer the operator voice call converted into the VOIP voice call on other terminals, and thus the user can answer the operator voice call on any terminal owned by the user in real time and reduce the call charge.

In the application scenario as shown in fig. 1, when the call method provided by the present application is used, when a customer calls the phone number of the terminal a, the operator voice call for the terminal a can be converted into a VOIP voice call between the terminal a and the terminal B, and the user can answer the call through the terminal B, so as to ensure that the user can normally talk with the customer.

Before describing a specific technical solution of the embodiment of the present application, a communication system according to the embodiment of the present application will be described with reference to the drawings. Referring to fig. 2, a communication system according to an embodiment of the present application is schematically illustrated. The communication system comprises a terminal A, a terminal B, a terminal C and a cloud network, wherein the cloud network can be the Internet and is used for forwarding data based on the IP address of the terminal. It should be noted that, in practical applications, the number of terminals may be one or more, and the number of terminals in the communication system shown in fig. 2 is only an adaptive example, which is not limited in this application. It should be further noted that the cloud network includes, but is not limited to, one or more cloud servers and other devices, and the present application is not limited thereto.

The terminal in fig. 2 may be a device that provides voice or data connectivity to a user, and may also be referred to as a mobile station (mobile station), a subscriber unit (subscriber unit), a station (station), a Terminal Equipment (TE), etc. The terminal may be a cellular phone (cellular phone), a Personal Digital Assistant (PDA), a smart phone, a notebook computer, a tablet computer (PC), a pager, a portable computer, a portable game machine, a wearable electronic device, or other mobile communication devices having components for transmitting voice or data over a wireless communication network. The terminals may be stationary or mobile.

With reference to the communication system shown in fig. 2, in the present application, a terminal a is taken as a calling end, a terminal B is taken as a called end (which may also be called an intermediate device or a forwarding end), and a terminal C is taken as a terminal used by a user to answer a call, which may be referred to as an answering end for short. For example, in an application scenario of the present application, the terminal a is a mobile phone used by another user, the terminal B is a mobile phone that the user has left out at home, and the terminal C is a mobile phone currently carried by the user. It should be noted that the terminal B may be understood as a first terminal (or a first electronic device) according to the present application, the terminal a may be understood as a second terminal (or a second electronic device) according to the present application, and the terminal C may be understood as a third terminal (or a third electronic device) according to the present application.

Referring to fig. 2, as shown in fig. 4, a schematic flow chart of a call method in the embodiment of the present application is shown, where in fig. 4:

step 101, terminal B receives operator voice call of terminal a, and the call object of the operator voice call is the operator number of terminal B.

In this application, terminal a initiates a voice call to terminal B based on the SIM card number in terminal B, where the voice call may be specifically referred to as an operator voice call, and may be understood as a voice call initiated through an operator network and based on the SIM card number. In the present application, the voice calls can be specifically classified into two types, one is an operator voice call initiated based on the SIM card number, and the other is a VOIP voice call initiated based on the VOIP technology.

Step 102, the terminal B initiates a VOIP voice call to the terminal C based on the network address of the terminal C in response to the received operator voice call.

Specifically, after receiving the operator voice call from the terminal a, the terminal B detects whether the terminal B has started the VOIP call forwarding function. If the VOIP call forwarding function is detected to be started, the terminal B can initiate a VOIP call to a forwarding object set in the VOIP call forwarding function, namely the terminal C in the application. Specifically, the terminal B may send a VOIP call request message to the terminal C after querying that the forwarding object is the terminal C, for establishing a VOIP connection with the terminal C. Optionally, the VOIP call request message may carry a SIM card number of the terminal a, which is used to indicate that the current VOIP voice call is a VOIP voice call forwarded based on the operator voice call of the terminal a (specifically, the SIM card number of the terminal a).

Step 103, terminal B receives the response message sent by terminal C.

Specifically, after receiving the VOIP voice call request message from the terminal B, the terminal C may display the VOIP voice call on the display screen of the terminal C and wait for the operation instruction of the user. Optionally, after receiving an operation instruction triggered by the user and instructing to connect the VOIP voice call, the terminal C may return a VOIP voice call response message (which may also be referred to as a listen indication message) to the terminal B to instruct to connect the VOIP voice call. After the terminal B receives the response message, the VOIP voice channels of the terminal B and the terminal C are successfully established, and the terminal B and the terminal C interact with the VOIP message through the VOIP voice channel, that is, the message has the network format supporting the VOIP transmission network.

And step 104, the terminal B responds to the received response message and connects the voice call of the operator.

Specifically, the terminal B may connect the operator voice call from the terminal a based on the VOIP voice call response message, or may understand that the terminal a and the terminal B establish an operator voice channel, and the terminal B may interact operator voice data (or signals) with the terminal a. Optionally, the terminal B serves as a transfer terminal, and may convert the operator voice of the terminal a into the VOIP voice and send the VOIP voice to the terminal C, or convert the VOIP voice of the terminal C into the operator voice and send the operator voice to the terminal a, so as to implement the call between the terminal a and the terminal C, as shown in fig. 5. It should be noted that, in the transfer process of the terminal B, the audio module of the terminal B is turned off, that is, the microphone of the terminal B does not input voice, and the receiver of the terminal B does not output voice.

Step 105, the terminal B converts the operator voice data from the terminal a into VOIP voice data and sends the converted VOIP voice data to the terminal C, and the terminal B converts the VOIP voice data from the terminal C into operator voice data and sends the converted operator voice data to the terminal a.

Specifically, in the embodiment of the present application, the terminal B may generate VOIP voice data by performing internal conversion on the received operator voice data, and send the VOIP voice data to the terminal C. Optionally, the terminal B may also internally convert the received VOIP voice data to generate operator voice data and send the operator voice data to the terminal a. The specific implementation process of terminal B for converting voice will be described in detail in the following embodiments.

It should be noted that, in the present application, the terminal B needs to perform a voice conversion (or forwarding) operation, and therefore, the terminal B is a terminal with a SIM card function, that is, the terminal B includes a SIM card interface shown in fig. 3 to process an operator voice call initiated by another terminal to at least one SIM card number in the terminal B. In the present application, the terminal C is only used to connect the VOIP voice call switched by the terminal B, so the terminal C may be a terminal having a SIM card function (i.e. capable of processing the operator voice call) and a VOIP function (i.e. capable of processing the VOIP voice call), such as a mobile phone, or a terminal having only the VOIP function, such as a tablet, a smart watch, an earphone, a large screen, or a notebook.

In one possible implementation, terminal C may also make a call to terminal a through terminal B and talk. Specifically, the terminal C may establish a VOIP voice channel with the terminal B, and send a VOIP call request message to the terminal B, where the VOIP call request message may carry an SIM card number of the terminal a to indicate that the terminal B initiates an operator voice call to the terminal a, and the terminal B may send the operator voice call request message to the terminal a based on the request message of the terminal C, and after the terminal a is connected, also convert the operator voice of the terminal a and the VOIP voice of the terminal C, so as to implement a call between the terminal a and the terminal C. In this scenario, assuming that the user only goes out with the tablet, in the presence of a wireless network, the user may initiate a VOIP call to another terminal of the user through the tablet, and make a voice call to a terminal that the user wants to call through the terminal.

In a possible implementation manner, the terminal B may be further configured to perform VOIP voice signal conversion on the received operator information, for example, a short message, so that the user acquires the operator information received by the terminal B through the terminal C. Specifically, after the terminal B receives the operator information, the terminal B may initiate a VOIP voice call to the terminal C, and after the terminal B detects that the terminal C connects the VOIP voice call, the terminal B may read the text information in the operator information, convert the text information into voice information, and send the voice information to the terminal C through a VOIP voice channel established with the terminal C. Correspondingly, after receiving the voice message, the terminal C may play the voice message through a speaker or an earphone so that the user may obtain the text content of the operator information received by the terminal B. The method can be applied to a scene that a user logs in a website or APP through a verification code, for example, the user needs to log in a website, the user registers in the website by using an operator number of a terminal B before, the user can open an address of the website on a terminal C, fill in the operator number of the terminal B, select to log in through the verification code, the website sends the verification code to the terminal B after receiving a request message, optionally, the verification code is sent in a form of an operator short message, and after the terminal B receives the verification code short message, the terminal B can send the verification code to the terminal C in a VOIP voice mode, so that the operator information sent to the terminal B can be conveniently and quickly acquired even if the user does not carry the terminal B with him.

The technical solutions of the above method embodiments are described in detail below using several specific examples. Specifically, in the following embodiments, the first part is a specific flow of the call method in the embodiment of the present application, and the second part is an internal flow of the terminal B in the embodiment of the present application for implementing voice forwarding. Specifically, in the first section, the communication method of the present application is specifically divided into two types: the first is that a terminal a calls a terminal B, and the terminal B converts the operator voice of the terminal a into VOIP voice to realize the call between the terminal a and the terminal C, specifically see the first scenario. The second method is that the terminal C dials to the terminal B through the VOIP technology, so that the operator voice call is initiated to the terminal A through the terminal B, and the conversation between the terminal C and the terminal A is realized, specifically seen in a second scene.

The first part

Scene one

Referring to fig. 2, as shown in fig. 6, a schematic flow chart of a call method in the embodiment of the present application is shown, where in fig. 6:

step 201, terminal a initiates an operator voice call to terminal B.

Specifically, the terminal a may perform an operator voice call to the terminal B based on the SIM card number of the terminal B. For example, the terminal a may send an operator voice call request message to the terminal B, it should be noted that the operator voice call request message sent by the terminal a to the terminal B actually needs to be processed by an operator server and other devices before reaching the terminal B side. Optionally, the operator voice call request message carries a number of the terminal a, and for example, the number of the terminal a may be a SIM card number in the terminal a.

Step 202, the terminal B and the terminal C establish a VOIP voice channel.

Specifically, the terminal B receives the operator voice call request message from the terminal a, and acquires the number (for example, the SIM card number) of the terminal a carried in the request message. Terminal B may establish a VOIP voice connection, otherwise referred to as a VOIP voice channel, with terminal C.

Optionally, in this application, the terminal B may initiate a VOIP voice call to the terminal C through the cloud network to establish a VOIP voice channel between the terminal B and the terminal C.

Fig. 7 shows an internal flow chart of terminal B initiating a VOIP voice call. Specifically, in the present application, the AP processor of the terminal B may include a call management module, for example, the call management module may be a telephone communication (telecommunications) module B, a connection Service (Service) module B, and a VOIP Service module B in an android system, where the telecommunications module B is used to process all voice calls in the terminal, including answering and hanging up. The VOIP Service module B is used for processing VOIP voice calls. And the Service module B is connected with the Service module B, which can also be called a transfer Service module, a scheduling Service module and the like, and is used for realizing the conversion between the voice call of the operator and the VOIP voice call. Referring to fig. 7, specifically, the terminal a initiates an operator voice call to the terminal B, for example, the terminal a sends an operator voice call request message to the terminal B through the server, and after the Telecom module B obtains the operator voice call request message from the terminal a, the Telecom module B may send a notification message to the successive Service module B to indicate that the operator voice call from the terminal a currently exists, or may understand that the operator voice call indicates that the terminal a makes an incoming call. The connection Server module B queries whether the terminal B has started the voice forwarding function (which refers to the function of forwarding the operator voice call and the VOIP voice call in this application) by calling the local configuration. If the terminal B is inquired to start the function, the Service module B further inquires the configuration to determine the switching strategy. Illustratively, the transition strategy may include a continuation strategy as well as a resonance strategy. Wherein, the connection strategy is used for indicating whether to reject other incoming calls in the voice conversion process. The resonance strategy is then used to indicate the transition object, also understood as a terminal that resonates with terminal B. In the embodiment of the present application, the successive Service may determine an object to be transferred based on a resonance strategy, and exemplarily, the transferred object is the terminal C. Optionally, after the connection Service module B determines that other incoming calls need to be rejected based on the connection policy, a connection indication may be sent to the Telecom module B, and after the Telecom module B receives the indication, the terminal B may be set to a state of rejecting other incoming calls (or calls) based on the indication, that is, before the terminal B disconnects the call between the terminal a and the terminal C, or it may be understood that the terminal B rejects other incoming calls in the process of performing voice conversion between the terminal a and the terminal C.

For example, as shown in fig. 8, which is an operation diagram illustrating a voice forwarding function of the user setting terminal B, the user may select an object to which the terminal B forwards the operator voice call in a prompt box provided by the terminal B. The terminal B stores identification information of a forwarding object (e.g., the terminal C), optionally, the identification information may be IP address information of the terminal C, or hardware address information of the terminal C, and the like. Alternatively, as shown in fig. 8, the user may select a plurality of terminals as the transfer target at the same time.

Still referring to fig. 7, specifically, after the subsequent Service module B determines the object to be transferred, the subsequent Service module B sends a call request message to the VOIP Service module B. Illustratively, the call request message includes, but is not limited to: the SIM card number of terminal a. After receiving the call request message, the VOIP Service module B sends a VOIP voice call request message to the cloud network, where the request message includes but is not limited to: the SIM card number of terminal a and the identification information of terminal C. Optionally, before the VOIP Service module B sends the message to the cloud network, the message may be packaged into a network format supporting a VOIP transmission network so that the cloud network can parse the message.

In one example, after receiving the VOIP voice call request message from the terminal B (specifically, the VOIP Service module B), the cloud network may establish a VOIP voice channel between the terminal B and the terminal C through the VOIP cloud call technology. In another example, the cloud Network may establish a VOIP voice channel between the terminal B and the terminal C through a Network Address Translation (NAT) technology, which may also be referred to as NAT traversal technology.

For example, taking the example that the cloud network establishes the VOIP voice channel between the terminal B and the terminal C through the NAT traversal technology, after receiving the VOIP voice call request message, the cloud network queries the address information corresponding to the terminal C based on the identification information of the terminal C carried in the request message, and sends the VOIP voice call request message to the terminal C based on the address information, where the voice call request message includes, but is not limited to: the SIM card number of terminal a. Optionally, the request message may further carry indication information for indicating that the VOIP voice call is forwarded through the terminal B.

Referring to fig. 9, the terminal C also includes a VOIP Service module C and a Telecom module C, as shown in fig. 9, which is a schematic flow diagram for establishing a VOIP voice channel between the terminal C and the terminal B. Alternatively, the terminal C may also include a subsequent Service module C, but since the terminal C does not involve a voice forwarding operation in the embodiment of the present application, the subsequent Service module C of the terminal C is not shown in fig. 9.

Specifically, the VOIP Service module C in the terminal C receives the VOIP voice call request message from the cloud network, and sends the VOIP voice call request message to the Telecom module C. After receiving the request message, the Telecom module C can obtain the SIM card number of the terminal a carried in the request message, and display the current VOIP incoming call on the screen of the terminal C, and the caller is the terminal a. Optionally, if the request message carries the above indication information, the Telecom module C may further display the current VOIP incoming call on the screen of the terminal C to be the operator voice call forwarded from the terminal a (135 × 321) by the terminal B, as shown in fig. 10. The user may trigger a listen operation on the screen of terminal C to listen to the call from terminal a.

Still referring to fig. 9, specifically, after detecting the user instruction indicating answering the incoming call triggered by the user, the Telecom module C may send an answering indication message to the VOIP Service module C, where optionally, the answering indication message may include but is not limited to: the identification information (optional) of the terminal C, the SIM card number of the terminal a, and the identification information (e.g. IP address information) of the terminal B, where the message is used to instruct the terminal C to answer the VOIP call, and may also be understood as instructing the terminal B to connect the operator voice call (or called call or incoming call) of the terminal a. And the VOIP Service module C forwards the answering indication message to the cloud network. After receiving the answering indication message, the cloud network sends the answering indication message to the terminal B, so that the VOIP voice channel between the terminal B and the terminal C is successfully established, and the terminal B and the terminal C can mutually transmit the VOIP message based on the channel.

In step 203, the terminal B converts the operator voice call and the VOIP voice call.

Specifically, after receiving the answering indication message from the terminal C, the terminal B determines to answer the operator voice call of the terminal a. The terminal B can be connected with the operator voice call of the terminal A, and in the subsequent call process, the terminal B can convert the operator voice call of the terminal A into a VOIP voice call and send the VOIP voice call to the terminal C, and can also convert the VOIP voice call of the terminal C into the operator voice call and send the operator voice call to the terminal A. It should be noted that the conversion of the voice call by the terminal B is actually to convert the audio signal (or data) during the voice call, and the specific conversion process will be specifically described in the following embodiments.

For example, referring to fig. 11, after receiving the answering indication message sent by the cloud network, the terminal B (specifically, the VOIP Service module B in the terminal B) may send the answering indication message to the Telecom module B. After receiving the answering instruction message, the Telecom module B can execute linkage answering operation, namely, the terminal B can be controlled to connect operator voice call of the terminal A, and the Telecom module B sends the answering instruction message to the terminal A so as to realize operator voice call with the terminal A. Still referring to fig. 11, the Telecom module B sends a linkage answering request message to the continuing Service module B for triggering the continuing Service module B to execute an audio processing operation, i.e. a voice conversion (or called as call conversion, voice call conversion, etc.) process, and the specific process will be described in detail in the second part. Optionally, the terminal B disables the audio module, i.e. disables the microphone and the receiver of the terminal B, when performing the voice conversion process. Alternatively, if the terminal B receives the operator voice call initiated by the other terminal during the voice conversion, the terminal B hangs up the operator voice call (or incoming call) of the other terminal.

In one possible implementation, the user may select to hang up the call with terminal a on terminal C. The terminal C (specifically, the VOIP Service module C) can send a hang-up request message to the cloud network, and the cloud network sends the hang-up request message to the VOIP Service module B in the terminal B and forwards the hang-up request message to the Telecommunications module B. The Telecom module B may perform an internal hang-up operation, i.e., hang-up the operator voice call of the terminal a. Subsequently, the Telecom module B may send a connection hang-up request message to the successive Service module B to instruct the successive Service module B to stop the audio processing operation, i.e., stop the voice conversion. Alternatively, after the Service module B stops the audio processing operation, the audio module may be enabled, i.e., the microphone and the earpiece of the terminal B are turned on.

In a possible implementation, it may also be that terminal B hangs up the call between terminal C and terminal a. For example, after the terminal C is disconnected and the VOIP connection between the terminal B and the terminal C is disconnected, the terminal B may hang up the operator voice call of the terminal a, and the VOIP Service module B sends a hang-up request message to the Telecom module B. The Telecom module B may perform an internal hang-up operation, i.e., hang-up the operator voice call of the terminal a. Subsequently, the Telecom module B may send a connection hang-up request message to the successive Service module B to instruct the successive Service module B to stop the audio processing operation, i.e., stop the voice conversion. Alternatively, after the Service module B stops the audio processing operation, the audio module may be enabled, i.e., the microphone and the earpiece of the terminal B are turned on.

In a possible implementation, it may be that the terminal a hangs up the call between the terminal a and the terminal C. The terminal B detects (for a specific detection process, refer to the prior art, which is not described herein) that after the terminal a hangs up the voice call with the operator, the VOIP voice channel with the terminal C can be disconnected. Illustratively, the Telecom module B in terminal B may perform an internal hang-up operation, i.e., hang-up the operator voice call of terminal a. Subsequently, the Telecom module B may send a connection hang-up request message to the successive Service module B to instruct the successive Service module B to stop the audio processing operation, i.e., stop the voice conversion. And the Telecommunications module B sends a hang-up instruction to the VOIP Service module B, and sends the hang-up instruction to the VOIP Service module C in the terminal C through the VOIP Service module B and the cloud network, and the VOIP Service module C is disconnected from the VOIP connection between the terminal B and the VOIP Service module C. And the VOIP Service module C sends a hang-up instruction to the Telecom module C, and the Telecom module C can display that the call is hung up on the terminal C based on the instruction. Alternatively, after the Service module B stops the audio processing operation, the audio module may be enabled, i.e., the microphone and the earpiece of the terminal B are turned on.

In a possible implementation manner, the scenario to which the present application is applied may also be a scenario in which a plurality of transfer objects exist. For example, as shown in fig. 8, the user may also set the terminal D and the terminal E as the transfer object, and in this scenario, the interaction between the terminal B and the terminal D and the interaction between the terminal E are the same as the interaction between the terminal B and the terminal C, which is not described in detail herein. In one example, the terminal B may establish the VOIP voice channel with only any one of the forwarding objects, that is, which terminal first receives the VOIP voice call, the terminal B performs call forwarding between the terminal and the terminal a and disconnects the VOIP channel with other forwarding objects. In another example, terminal B may also establish a VOIP voice channel with multiple transit objects simultaneously, that is, terminal B may implement a call between terminal a and multiple transit objects, such as terminal C, terminal D, and terminal E.

In yet another possible implementation manner, there may be a plurality of intermediate devices, and for example, the user owns the terminal B1, the terminal B2, the terminal B3, and the terminal C. The user can set the transit subjects of both the terminal B1 and the terminal B2 as the terminal C. In one example, if terminal B1 receives the operator voice call of terminal a1 and terminal B2 receives the operator voice call of terminal a2, terminals B1 and B2 may simultaneously establish a VOIP channel with terminal C, terminal B1 may convert the operator voice call of terminal a1 and the VOIP voice call of terminal C, and terminal B2 may convert the operator voice call of terminal a2 and the VOIP voice call of terminal C to realize a multi-terminal call, that is, terminal C may simultaneously talk with terminals a1 and a 2. In another example, terminal C may choose to talk to only one party (terminal A1 or terminal A2).

In another possible implementation manner, the number of the intermediate devices and the number of the switching devices may be multiple, which is not limited in this application.

Scene two

Referring to fig. 2, as shown in fig. 12, a schematic flow chart of a call method in the embodiment of the present application is shown, where in fig. 12:

specifically, the terminal C initiates a VOIP voice call request message to the terminal B. Referring to fig. 12, the Telecom module C in the terminal C receives a user instruction triggered by a user, and sends a VOIP call request message to the VOIP Service module C, and after receiving the request message, the VOIP Service module C sends the VOIP voice call request message to the terminal B, where the request message includes, but is not limited to: the SIM card number of terminal a, the identification information (e.g., address information) of terminal B, and the identification information (e.g., address information) of terminal C are used to instruct terminal B to initiate a carrier voice call to terminal a and to convert a voice call between terminal a and terminal C. Specifically, in fig. 12, the VOIP Service module C sends the VOIP voice call request message to the cloud network, so as to forward the VOIP voice call request message to the terminal B through the cloud network.

Specifically, after receiving the VOIP voice call request message, the VOIP Service module B in the terminal B sends a notification message to the subsequent Service module B to indicate that the VOIP voice call from the terminal C currently exists, and the object of the voice call is the terminal a. And continuing the query configuration of the Service module B, and determining that the terminal B starts the voice switching function, wherein the specific details can refer to the first scene, which is not described herein again. Then, the continuing Service module B sends an operator voice call request message to the Telecom module B to instruct to initiate an operator voice call to the terminal a. The Telecom module sends operator voice call request information to the terminal A so as to request the information to carry out operator voice call with the terminal A. The details of the interaction can be found in the prior art and are not described herein. Illustratively, the incoming call number displayed on terminal a is the SIM card number of terminal B.

Still referring to fig. 12, after the terminal a confirms that the operator voice call initiated by the terminal B is answered, an answering instruction message is sent to the terminal B, and after the terminal B (specifically, the Telecom module B in the terminal B) receives the answering instruction message, the Telecom module B performs a linkage answering operation and sends a linkage answering request message to the connection Service module B. And the Service connecting module B receives the linkage answering request message and executes audio processing operation. For specific details, reference may be made to scenario one, which is not described herein again. And the Telecom module B sends the answering indication message to the terminal C through the VOIP Service module B and the cloud network so as to indicate that the call between the terminal C and the terminal A is connected. Specifically, after receiving the answer instruction message, the VOIP Service module C in the terminal C sends the answer instruction message to the Telecom module C, and optionally, after receiving the answer instruction message, the Telecom module C can display that the VOIP voice call is connected on the terminal screen to notify the user that the call is connected.

In a possible implementation manner, the call between the terminal a and the terminal C may be hung up by the terminal C, hung up by the terminal B, and/or hung up by the terminal a, and specific details may refer to the scenario one, which is not described herein again.

The second part

Fig. 13 is a schematic structural diagram of a terminal B, in which the AP processor includes, but is not limited to, a High-Fidelity (High-Fi) module and an audio processing module, and the High-Fi module is configured to process, specifically, encode and decode, a carrier voice signal. The audio processing module is used for processing the VOIP voice signal, and specifically, encoding and decoding the VOIP voice signal. The audio processing module may be, for example, a Huawei Media Engine (HME), which is not limited in this application.

For example, in the prior art, if the terminal B answers the operator voice call through the Modem, in the call process, the Hi-Fi module acquires an analog audio signal collected by an audio module, for example, a microphone in the audio module, encodes the analog audio signal, generates an operator voice signal, and sends the operator voice signal through the Modem. And the Hi-Fi module can also encode the operator voice signal acquired by the Modem and output the encoded operator voice signal to the audio module so as to output an analog audio signal through a loudspeaker and other modules in the audio module. The audio processing module has a function similar to that of the Hi-Fi module, and is mainly used for converting analog audio signals collected by a microphone into VOIP voice signals to be output, and/or converting the received VOIP voice signals into analog audio signals to be output through modules such as a loudspeaker of the audio module.

On the basis of fig. 13, fig. 14 is a schematic diagram illustrating an exemplary speech conversion. Referring to fig. 14, in an example, after receiving the operator voice signal, the Hi-Fi module may re-encode the operator voice signal, where the re-encoded format may be, for example, a PCM code stream format, or another negotiation format that can be read by the audio processing module, and the application is not limited in this application. Specifically, the Hi-Fi module sends the recoded data to the audio processing module, and the audio processing module recodes the data into VOIP voice data after receiving the data, and outputs the VOIP voice data, for example, to the terminal C. In another example, after receiving the VOIP voice signal, the audio processing module may re-encode the VOIP voice signal, and for example, the re-encoded format may also be a PCM code stream format, which is not limited in this application. Specifically, the audio processing module sends the recoded data to the Hi-Fi module, and the Hi-Fi module recodes the data into operator voice data after receiving the data, and outputs the operator voice data through the Modem, for example, to the terminal a.

For example, in the embodiment of the present application, the successive Service module B may also be used to schedule the encoded data of the Hi-Fi module and the audio processing module. In one example, after the Hi-Fi module re-encodes the operator voice data, the Service module B is connected to obtain the re-encoded data, and write the re-encoded data into a configuration file (e.g., a Buffer file) of the audio processing module, and the audio processing module reads the configuration file, obtains the data re-encoded by the Hi-Fi module, and performs secondary encoding on the data to generate the VOIP voice data. In another example, after the audio processing module re-encodes the VOIP voice data, the Service module B is connected to obtain the re-encoded data and write the re-encoded data into the configuration file of the Hi-Fi module, and the Hi-Fi module reads the configuration file, obtains the re-encoded data, and performs secondary encoding on the data to generate the operator voice data.

Illustratively, as shown in fig. 14, during enabling of the Hi-Fi module and the audio module, i.e., during inter-conversion of the operator voice data and the VOIP voice data, the processor may control disabling of the audio module, e.g., disabling of software interfaces of a voice acquisition module, e.g., a microphone, and a voice output module, e.g., a speaker, in the audio module, so as to disable the voice acquisition module and the voice output module.
