[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0041] 5G New Call is an upgrade to traditional audio and video calls. 5G New Call can support the real-time transmission of multimedia data such as emoticons and pictures, thereby greatly improving the fun of calls and the user experience.

[0042] However, in reality, when users use a new application or service, they may encounter cumbersome setup or registration procedures, which is not user-friendly for special groups such as the elderly, children, or the hearing impaired. In such cases, users often need to seek help from relatives, friends, or customer service for remote guidance. Currently, the call quality of 5G calls cannot be guaranteed, and the real-time nature of interactive information during calls is poor, affecting call quality. For example, during calls, issues such as stuttering and delays in the transmission of interactive information may occur.

[0043] To improve call quality and the real-time nature of interactive information, embodiments of this application provide a call method, a terminal, and an electronic device. This call method can provide remote guidance to special groups, enabling real-time, barrier-free communication between these groups and remote users. The remote user can be a real user or an intelligent customer service system.

[0044] The following description, in conjunction with the accompanying drawings, details the call method, terminal, and electronic device provided in this application through specific embodiments and application scenarios.

[0045] Figure 1 This is a schematic diagram illustrating an application scenario of a call method provided in an embodiment of this application, such as... Figure 1As shown, this application scenario may include a first terminal 101, a second terminal 102, a first proxy device 103, a second proxy device 104, and a network-side device 105. The network-side device 105 may, for example, include an IP Multimedia Subsystem (IMS).

[0046] The first terminal 101 and the second terminal 102 can be terminals with call functions, such as devices that support audio and video transmission, such as mobile phones, tablets, and laptops.

[0047] In some embodiments, the first terminal 101 can interact with the second terminal 102 through the first proxy device 103 and the second proxy device 104 in sequence. Correspondingly, the second terminal 102 can interact with the first terminal 101 through the second proxy device 104 and the first proxy device 103 in sequence.

[0048] In some embodiments, the first terminal 101 may also interact directly with the second terminal 102.

[0049] In some embodiments, the first terminal 101 and the second terminal 102 may also interact with the network-side device 105 respectively.

[0050] The first terminal 101 and the second terminal 102 can communicate remotely with the help of the first proxy device 103, the second proxy device 104 and the network side device 105, so as to realize real-time barrier-free communication between special groups and remote users.

[0051] Figure 2 A flowchart illustrating a call method provided in this application embodiment, the call method can be generated by... Figure 1 The first terminal shown can be a terminal used by a user who wants to obtain remote assistance. In some embodiments, the first terminal can be a terminal used by special groups of people, such as a mobile phone, tablet computer, or laptop computer.

[0052] like Figure 2 As shown, the call method may include the following steps:

[0053] S210, If the first terminal and the second terminal establish an IP Multimedia Subsystem (IMS) call connection, send an Application Data Channel (ADC) establishment request to the second terminal to establish an ADC with the second terminal.

[0054] S220: Receive the confirmation information sent by the second terminal corresponding to the ADC establishment request.

[0055] S230. During an IMS call, shared information is sent to the second terminal via the ADC.

[0056] S240: Receive feedback information corresponding to the shared information sent by the second terminal via ADC.

[0057] In this embodiment, when an IMS call connection is established between the first terminal and the second terminal, an ADC is established with the second terminal. During the IMS call, shared information is sent to the second terminal via the ADC, and feedback information corresponding to the shared information sent by the second terminal is received via the ADC. That is, in this embodiment, during the IMS call, shared information and corresponding feedback information are transmitted through an additionally established ADC, no longer sharing a channel with other information. This avoids data packet loss, lag, and other issues, reduces delays caused by queuing, and improves the service quality of the call and the real-time nature of the interactive information.

[0058] The above steps are explained in detail below:

[0059] In S210, before the first user can communicate with the second user through the first terminal, an IMS communication connection needs to be established between the first and second terminals. The second terminal is the terminal used by the second user, who can provide remote assistance to the first user through the second terminal.

[0060] For example, the first terminal can establish an IMS call connection with itself in the following manner:

[0061] Send a call invitation signal to the second terminal;

[0062] Upon receiving a response message from the second terminal in response to the call invitation signaling, an IMS call connection is established.

[0063] For example, when the first terminal receives call input from the first user to the second user, it can send a call invitation signaling to the second terminal. This call invitation signaling can be a voice call invitation signaling or a video call invitation signaling.

[0064] If the second user accepts the call invitation, the second terminal can send a response message to the first terminal, indicating that the IMS call connection between the first and second terminals has been successfully established. If the second user rejects the call invitation, the second terminal can wait for the next call invitation to be initiated.

[0065] In this embodiment of the application, an IMS call connection is established between the first terminal and the second terminal before the call is made. After the second terminal accepts the call invitation, subsequent operations are performed, thus ensuring the validity of the call.

[0066] The ADC establishment request is used to request the establishment of an ADC with the second terminal, providing a basis for improving the service quality of the call and the real-time nature of the interactive information.

[0067] For example, after establishing an IMS call connection with the second terminal, the first terminal can send an ADC establishment request to the second terminal.

[0068] In S220, the confirmation message is used to indicate that the ADC has been successfully established. Subsequently, the first terminal can transmit shared information to the second terminal through the ADC without having to share a channel with other data. This can avoid data packet loss, lag, and other issues, reduce delays caused by queuing, and improve the service quality of the call and the real-time nature of the interactive information.

[0069] For example, after receiving the ADC establishment request, the second terminal can establish the corresponding ADC and return confirmation information to the first terminal to notify the first terminal that the ADC establishment is complete, which helps the first terminal to perform subsequent operations.

[0070] In S230, the shared information here can be information shared by a first user to a second user, in the expectation that the second user will provide assistance based on the shared information. For example, the shared information may include shared files, screen sharing, etc. Shared files may include, but are not limited to, documents, images, etc.

[0071] For example, if the first user does not understand a certain passage in document 1, document 1 can be shared with the second user.

[0072] In some embodiments, shared information can be transmitted to the second terminal via a pre-established ADC, or via a video channel between the first and second terminals.

[0073] In S240, the feedback information corresponding to the shared information may include, but is not limited to, subtitle data corresponding to the voice data, shared information carrying annotation information, coordinate information corresponding to the annotation information, etc.

[0074] The above feedback information can be transmitted through the same ADC or through different ADCs.

[0075] In order to establish an ADC between the first terminal and the second terminal, Figure 3 An exemplary flowchart of a call method is provided. Figure 3 Taking the establishment of an IMS call connection between the first terminal and the second terminal as an example, Figure 3 and Figure 2 The difference is that, Figure 2 S210 in the middle can be further refined into Figure 3 S310-S320 in the series.

[0076] S310, In response to the first input, determine the remote assistance request information.

[0077] The first input is used to instruct the first user on the remote assistance service they require. For example, the first input may include, but is not limited to, voice input, gesture input, and touch input. For instance, the first user can provide the required remote assistance service to the first terminal via voice input.

[0078] For example, the first input may also include touch input from a first user. For instance, in some embodiments, the above-described S310 may include the following steps:

[0079] Display an interactive interface on the call screen, which includes multiple call service controls;

[0080] In response to the first input to the target call service control, determine the remote assistance request information corresponding to the target call service control, wherein the target call service control is at least one of a plurality of call service controls.

[0081] For example, the interactive interface can float above the call interface. For instance, when the first terminal receives a response message from the second terminal in response to the call invitation signaling, the interactive interface can be displayed on the call interface.

[0082] The interactive interface can include multiple call service controls, each representing a different call service. When the first user touches the corresponding call service control, it means that the first user wants to obtain the corresponding remote assistance request information.

[0083] For example, a call service control may represent only one call service. When the first user wants to obtain multiple call services, he / she can touch multiple call service controls. For example, the first input may include clicking on multiple call service controls, where the time interval between two clicks needs to be less than a preset time interval, such as 1 second.

[0084] For example, a call service control can also integrate multiple call services. When the first user wants to obtain multiple call services, they can directly touch the multi-functional call service control.

[0085] Single-function call service controls may include, for example, speech-to-text controls and shared information tagging controls, while multi-function call service controls may include, for example, caption assistance and shared information tagging service controls.

[0086] The first electronic device can determine the call service corresponding to the target call service control corresponding to the first input as the remote assistance requirement information needed by the first user, so that the corresponding ADC can be established based on the remote assistance requirement information.

[0087] The target call service control may include one or more. When there are multiple target call service controls, the first input may include the first user's click input on each target call service control, and the time interval between click inputs of two adjacent target call service controls is less than a preset time interval. For example, the first input may also be a sliding input along a certain trajectory. For instance, if there are three target call service controls, the first input may be the input that slides along a certain trajectory past the three target call service controls.

[0088] This embodiment provides a variety of call services to the first user through an interactive interface for the first user to choose from. Based on the first user's initial input to the interactive interface, the call service that the user needs to implement is determined. This allows the corresponding ADC to be dynamically established based on the first user's actual needs, which helps to improve the service quality of the call and the real-time nature of the interactive information.

[0089] S320. Based on the remote assistance request information, send an ADC establishment request to the second terminal to establish an ADC with the second terminal.

[0090] The ADC establishment request includes the number of ADCs, which is associated with remote assistance requirement information.

[0091] The number of ADCs corresponding to different remote assistance needs can be different. That is, this embodiment can adaptively determine the number of ADCs to be established based on the remote assistance needs of the first user, which can ensure the service quality of the call and the real-time nature of the interactive information.

[0092] This embodiment can determine the remote assistance service required by the first user based on the first input, and dynamically determine the number of ADCs based on the remote assistance service, so that the second terminal can establish a corresponding ADC based on the number, thus ensuring the improvement of service quality and the real-time nature of interactive information.

[0093] In some embodiments, the shared information may include shared files, and the feedback information corresponding to the shared information may include at least one of the following: annotation information, subtitle information corresponding to the voice data, and coordinate information corresponding to the annotation information.

[0094] The audio data here refers to the audio feedback from the second user regarding the shared information. The subtitle information is the data converted from the audio data; converting audio data into subtitle information can meet the needs of special users, such as hearing-impaired users.

[0095] In some embodiments, voice data can be transmitted via an audio channel between the first terminal and the second terminal, with the audio channel's Quality of Service (QoS) identifier being 5QI = 1. Annotation information can be compressed together with shared information and transmitted via a video channel between the first terminal and the second terminal. The video channel's QoS identifier is 5QI = 2, thus ensuring the QoS of both voice data and annotation information.

[0096] In some embodiments, the coordinate information corresponding to the subtitle information and annotation information can be transmitted through the corresponding ADC.

[0097] Taking the above-mentioned ADC as including a first ADC and a second ADC as an example, S230 may include the following steps:

[0098] During an IMS call, shared information is sent to the second terminal via the first ADC;

[0099] Accordingly, the above-mentioned S240 may include the following steps:

[0100] The system receives subtitle information sent by the second terminal via the second ADC, and receives a shared file containing annotation information and the coordinate information corresponding to the annotation information sent by the second terminal via the first ADC.

[0101] The first ADC and the second ADC are used to transmit different information. For example, in this embodiment, the first ADC is mainly used to transmit shared information, shared files with annotation information, and coordinate information corresponding to the annotation information, while the second ADC is mainly used to transmit subtitle information.

[0102] For example, when transmitting a shared file with annotation information and the coordinate information corresponding to the annotation information, the annotation information, the shared file, and the coordinate information can be compressed and transmitted together to ensure the synchronization of the annotation information, the shared file, and the coordinate information.

[0103] Using different ADCs to transmit subtitle information and other information such as annotation information and coordinate information can avoid problems such as data packet loss and transmission delay caused by sharing an ADC with other information, thus ensuring the transmission quality and timeliness of subtitle information and ensuring the synchronization of subtitles and audio.

[0104] In some embodiments, the ADC may include a third ADC, a fourth ADC, and a fifth ADC; that is, the ADC may include three ADCs. Accordingly, S230 may include the following steps:

[0105] During an IMS call, shared information is sent to the second terminal via the third ADC;

[0106] The above-mentioned S240 may include the following steps:

[0107] The fourth ADC receives subtitle information sent by the second terminal, the third ADC receives a shared file containing annotation information sent by the second terminal, and the fifth ADC receives coordinate information corresponding to the annotation information sent by the second terminal.

[0108] In this embodiment, the coordinate information corresponding to the subtitle information and the annotation information, as well as the shared file with the annotation information, are transmitted through different ADCs, which can ensure the transmission quality and timeliness of each piece of information, and thus ensure the quality and timeliness of the interactive information.

[0109] In some embodiments, the ADC may further include a sixth ADC and a seventh ADC; correspondingly, prior to S240, the communication method may further include the following steps:

[0110] In response to the second input, an enable request message is sent to the network-side device via the sixth ADC to request the network-side device to enable the speech-to-text function;

[0111] When the speech-to-text function is enabled, the network-side device converts the speech data sent by the second terminal into subtitle information and sends it to the first terminal through the seventh ADC.

[0112] In some embodiments, speech-to-text conversion can be implemented by a network-side device. When the first user needs subtitle assistance, the first terminal can be notified, and the first terminal will send an enable request to the network-side device. If the first user does not need subtitle assistance, the first terminal does not need to send an enable request to the network-side device.

[0113] The second input is used to request subtitle information corresponding to the voice data. For example, the second input may include the first user's click input on the speech-to-text control in the interactive interface, or it may be the first user's voice input or gesture input. After receiving the second input, the first terminal can send an enable request message to the network-side device through the sixth ADC, requesting the network-side device to enable the speech-to-text function.

[0114] Once the speech-to-text function is enabled, the network-side device can send a response message to the first terminal, informing it that the speech-to-text function has been enabled.

[0115] Once the speech-to-text function is enabled, the network-side device can convert the voice data sent by the second terminal into subtitle information and send it to the first terminal via the seventh ADC.

[0116] This embodiment establishes an additional data channel specifically for transmitting activation request information. Users can flexibly determine whether to enable the speech-to-text function according to their needs, thus meeting their personalized requirements. When the speech-to-text function is enabled, the first user can enjoy subtitle assistance services, facilitating real-time barrier-free communication with the other party.

[0117] Taking the feedback information corresponding to shared information, including annotation information, subtitle information corresponding to voice data, and coordinate information corresponding to annotation information, as an example, in some embodiments, the call method may further include the following steps:

[0118] Based on the coordinate information, the annotation information is mapped to the shared file, and the subtitle information corresponding to the audio data is displayed on the screen corresponding to the shared file.

[0119] For example, after receiving voice data and subtitle information, the first electronic device can match the voice data and subtitle information. The voice data can be played, and the subtitle information can be displayed on the screen synchronously. At the same time, the first terminal can map the annotation information to the corresponding position of the shared file based on the coordinate information of the annotation information, and present a real-time interface with annotations and language guidance subtitles to the first user.

[0120] Because various types of data are transmitted through their own dedicated data channels, data quality and real-time performance can be guaranteed, enabling real-time and barrier-free communication between the first user and the other party.

[0121] Figure 4 The flowchart illustrates a call method provided in an embodiment of this application. This call method can be executed by a second terminal, which may be a terminal capable of providing remote assistance.

[0122] like Figure 4 As shown, the call method may include the following steps:

[0123] S410, when the second terminal establishes an IP Multimedia Subsystem (IMS) call connection with the first terminal, receive the Application Data Channel (ADC) establishment request sent by the first terminal.

[0124] S420: Send an acknowledgment message corresponding to the ADC establishment request to the first terminal to establish an ADC with the first terminal.

[0125] S430: During an IMS call, receive shared information sent by the first terminal via ADC.

[0126] S440: Send feedback information corresponding to the shared information to the first terminal via ADC.

[0127] In this embodiment, when an IMS call connection is established between the first terminal and the second terminal, an ADC is established with the second terminal. During the IMS call, shared information is sent to the second terminal via the ADC, and feedback information corresponding to the shared information sent by the second terminal is received via the ADC. That is, in this embodiment, during the IMS call, shared information and corresponding feedback information are transmitted through an additionally established ADC, no longer sharing a channel with other information. This avoids data packet loss, lag, and other issues, reduces delays caused by queuing, and improves the service quality of the call and the real-time nature of the interactive information.

[0128] In some embodiments, the shared information includes shared files; the feedback information corresponding to the shared information includes annotation information, subtitle information corresponding to the voice data, and coordinate information corresponding to the annotation information.

[0129] In some embodiments, the ADC may include a first ADC and a second ADC;

[0130] Accordingly, the above-mentioned S430 may include the following steps:

[0131] During an IMS call, shared information sent by the first terminal is received via the first ADC.

[0132] The above S440 may include the following steps:

[0133] The second ADC sends subtitle information corresponding to the voice data to the first terminal, and the first ADC sends a shared file containing annotation information and the coordinate information of the annotation information to the first terminal.

[0134] In some embodiments, the above-mentioned ADC may include a third ADC, a fourth ADC, and a fifth ADC;

[0135] Accordingly, the above-mentioned S430 may include the following steps:

[0136] During an IMS call, shared information sent by the first terminal is received via the third ADC.

[0137] The above S440 may include the following steps:

[0138] The fourth ADC sends subtitle information to the first terminal, the third ADC sends a shared file containing annotation information to the first terminal, and the fifth ADC sends the coordinate information corresponding to the annotation information to the second terminal.

[0139] In some embodiments, the above-mentioned ADC may further include a seventh ADC;

[0140] Accordingly, after S430, the calling method may also include the following steps:

[0141] Send voice data corresponding to the shared information to network-side devices;

[0142] When the network-side device has the voice-to-text function enabled, the network-side device converts the voice data into subtitle information and sends it to the first terminal through the seventh ADC.

[0143] For specific details regarding the above content, please refer to the above embodiments. For the sake of brevity, these details will not be repeated here.

[0144] Taking a deaf-mute user as an example, this user may be the first user in the above embodiment. When registering for application A, the deaf-mute user encounters difficulties and needs remote assistance from other users. At this time, the deaf-mute user can share the page with the other user, who can then provide real-time guidance and step-by-step instructions on the page. The deaf-mute user will then see these real-time annotations and subtitles. Through the solution of this embodiment, the deaf-mute user can communicate with the other user in real-time without barriers, obtaining remote guidance and assistance, thus improving the user experience.

[0145] Taking the user providing remote assistance as the second user as an example, the following is combined with... Figure 5 The conversation between the two parties is described below. The first user uses terminal A, and the second user uses terminal B.

[0146] S510. Terminal A sends a call invitation signaling to Terminal B. Specifically, User Equipment A first sends the call invitation signaling to the first proxy device, which then sends it to the second proxy device, and finally the second proxy device sends it to Terminal B.

[0147] S520, Terminal B returns a confirmation message to Terminal A, indicating that the second user has accepted the call invitation from the first user, and the IMS call connection between Terminal A and Terminal B is established.

[0148] After receiving the remote assistance request from the first user via the interactive interface, terminal A sends an ADC establishment request to terminal B. Taking the establishment of three data channels as an example, namely ADC1, ADC2, and ADC3, the access network side corresponds to three Data Radio Bearers (DRBs) to carry the data required for each of the three data channels. Specifically, ADC1 transmits the request to enable the speech-to-text function (DRB4 on the access network side), ADC2 carries the text information (DRB0 on ​​the access network side), and ADC3 carries the coordinate information corresponding to the annotation information (DRB5 on the access network side). Voice data can be transmitted through the audio channel, and pages with annotation information can be transmitted through the video channel, ADC3, or any ADC other than ADC1, ADC2, and ADC3.

[0149] After S540 and ADC are successfully established, terminal B returns a confirmation message to terminal A.

[0150] S550 and Terminal A send an enable request to the VoNR+ media plane of the network-side device via ADC1, requesting the network-side device to enable the speech-to-text function.

[0151] The S560 and VoNR+ media interface return a message indicating that the voice-to-text function has been successfully enabled on terminal A.

[0152] S570, Terminal A sends shared information to Terminal B.

[0153] S580, Terminal B sends voice data to the VoNR+ media plane of the network-side equipment.
