Description

Technical Field

[0001] This application relates to the field of network communication technologies, and in particular, to a communication method and related devices. Background Art

[0002] In scenarios where the user is inconvenient to answer the phone (such as when having a meeting in the conference room), it is expected that there is an agent to assist in answering (i.e., the call assistant service).

[0003] When a traditional agent answers a call, it usually records the call and then notifies the user through the voicemail (voicemail service); or converts the voice into text and then sends it to the user via text message. In these methods, the user can only see or hear the content that the other party expects to convey after the call is hung up. This results in the user not being able to obtain the other party's message in real time.

[0004] Alternatively, in the prior art, some terminal operating systems have a button for assisted answering on the called user interface, which can receive the other party's message information in real time. However, the implementation of this button requires the development of specific user experience (UX) functions. The multimedia telephony service for IP multimedia subsystem (MTSI) client functions of the existing IP multimedia subsystem are limited, and there are only very limited functions such as answer and hang up in the ordinary call interface, which cannot cooperate to achieve the above requirements. How to enable existing mobile phones to also use the call assistant function, realize the process of the user viewing the other party's message content in real time when it is inconvenient to answer the phone, and during the viewing process, the called user can restore the call again through an instruction is an urgent problem to be solved. Summary of the Invention

[0005] Embodiments of this application provide a communication method and related devices, which can provide a call assistant function for terminal devices without additional UX design for the terminal, obtain the message information of the calling party, and keep the call during the process of obtaining the message information, which is helpful for restoring the call between the two parties in real time.

[0006] In a first aspect, this application provides a communication method, which is applied to a first terminal. The first terminal can be a terminal device or a chip in the terminal device. The method includes: receiving a first call request of a second terminal from a first server; sending a first message to the first server based on a first instruction, where the first message is used to indicate rejecting the first call request, and the first instruction is used to reject the call; receiving a second call request from the first server, where the second call request includes a customized ringing signal (CRS) service; keeping the ringing state with the second terminal based on the second call request, receiving a first message information from the second terminal sent through a second media resource, and displaying it.

[0007] In an embodiment of the present application, through a server (the first server) in IMS, when a first terminal subscribes to a call assistant service and a CRS service, after the user rejects a call from a second terminal, the call from the second terminal is retained, a second call request is initiated to the first terminal, and the CRS service is carried in the second call request, so that when the user of the first terminal is in the ringing state, the user can view the message information from the second terminal through CRS video. This process can provide a call assistant function for the terminal device without additional UX design for the terminal and reduce user operations, obtain the message information of the calling party, and keep the calling end in a call state during the process of obtaining the message information, which helps to resume the two-way call in real time.

[0008] In some possible implementation manners, the method further includes: sending a second message to the first server based on a detected second instruction, where the second message is used to indicate acceptance of the second call request, and the second instruction is used to accept a call.

[0009] In an embodiment of the present application, without adding additional UX design to the first terminal, the first terminal enters the call state with the second terminal in the message receiving state, ensuring the convenience and real-time nature of resuming the call.

[0010] In some possible implementation manners, before receiving the first message information from the second terminal sent through a second media resource, the method further includes: obtaining the second media resource from a media network element based on the CRS service.

[0019] In this embodiment, through the IMS server (the first server), when the first terminal subscribes to the call assistant service, after the user rejects the call from the second terminal, the call of the second terminal is retained, and a second call request is sent to the first terminal, so that the user of the first terminal can answer the message information from the second terminal by answering the second call request. This process can provide the call assistant function for the terminal device without additional UX design for the terminal, obtain the message information of the calling party, and keep the call of the calling end during the process of obtaining the message information, which helps to resume the two-way call in real time.

[0084] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0085] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present application and the accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0086] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0087] "Multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one of the following" or its similar expression is used to represent any combination of the items listed; for example, at least one of A, B, and (or) C can represent the following situations: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, B and C exist simultaneously, A and C exist simultaneously, and A, B, and C exist simultaneously, where A, B, and C can be single or multiple.

[0088] The application scenarios related to the embodiments of the present application are introduced below first.

[0089] Refer to Figure 1 , Figure 1 which is a schematic diagram of a communication scenario provided by the embodiments of the present application. As Figure 1 shown, in the communication scenario applied in the embodiments of the present application, it includes a UE and the home network of the UE. Among them, the home network of the UE includes an IP multimedia subsystem (IMS) application server (AS). Among them, the IMS AS is based on the multimedia telephone service of the IMS and realizes the interworking between the multimedia telephone (MMTel) and the traditional circuit-switched service through the media gateway control function (MGCF) and the media gateway (MGW) in the IMS core network. The media content in the IMS-AGW is provided by the media function (MF) network element. The incoming calls from other UEs are received and forwarded by the S-CSCF in the home network of the UE.

[0090] The baseband chip plus coprocessor (CP) of the UE includes a SIP protocol stack for signaling interaction based on the SIP protocol with the P-CSCF in the home network.

[0091] The following introduces the professional terms involved in the figure.

[0092] A terminal device, also known as a user equipment (UE), a terminal, etc. A terminal device is a device with wireless transceiver functions that can communicate with one or more core networks (CNs) via a radio access network (RAN). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on water, such as on a ship; it can also be deployed in the air, such as on an airplane, a balloon or a satellite, etc. A terminal device can be a mobile phone, a tablet (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0093] S-CSCF: It is in a core control position in the IMS core network and is responsible for UE registration authentication, conference control, user data management, etc.

[0094] P-CSCF: Proxy Call Session Control Function. It is the first connection point with the user in IMS and provides a proxy function, that is, accepting service requests and forwarding them. P-CSCF can also provide the user agent (UA) function in some cases.

[0095] IMS AGW (or Multimedia Gateway Function (IP Multimedia-Media Gateway Function, IM-MGW), or IM AGW): It has a similar function to P-CSCF.

[0096] MF: It is used to provide the management and control functions of media resources to support functions such as "multi-party calls and multi-party conferences".

[0097] The following introduces the prior art related to the embodiments of the present application.

[0098] Some terminal devices have implemented the phone assistant function. Specifically, it can include the following processes:

[0099] (1) The user's mobile phone rings. Refer toFigure 2 , Figure 2 This is a caller ID interface provided by an embodiment of the present application. As shown in (a) of Figure 2 , when the user's mobile phone receives an incoming call and rings, the contact interface is displayed. It may include the avatar and name of the caller, etc. Additionally, an answer button, a hang-up button, a message entry, and a reply text message entry may also be displayed.

[0100] (2) Receive a voice message. Since the user has subscribed to the mobile assistant service, after the call from the other party is answered, the IMS AS can remind the other party to leave a message and send the voice message content of the other party to the user's real-time voicemail (at this time, the user's mobile phone enters the connected state, but it is not a real two-way connection state, but the user's mobile phone receives the message from the other party without sending a voice packet to the other party). The terminal uses AI capabilities to convert the voice message into text to protect the user's privacy.

[0101] (3) The user views the text message. The user can operate the voice message entry on the mobile phone interface to view the text message. Specifically, refer to Figure 2 in (b). After the user clicks the "message entry", the message text is displayed on the interface.

[0102] (4) The user answers the call. After the user views the text message, the user can decide whether to answer the call according to the importance level (at this time, it enters the two-way call state).

[0103] It should be noted that when the user's mobile phone receives the voice message from the other party, the green answer button is still displayed on the mobile phone interface, which is a special enhancement in the user interface (UI). So that the user can operate the button to enter the real two-way connection state.

[0104] The above-mentioned prior art has the following defects: It requires the cooperation of the terminal interface for UX interface development. There are auxiliary answer buttons on the called user interfaces of the above-mentioned terminal devices for operating to answer messages, and such buttons require specific UX function development. The existing IMS multimedia telephony service for IMS (MTSI) client has limited functions. There are only very limited functions such as answer and hang up in the normal call interface, and it cannot cooperate to achieve the above requirements. The reason is that the UX interface needs to be specifically customized and developed. And if this function is implemented, a commercial closed-loop cannot be achieved. Therefore, how to realize the process of the MTSI terminal supporting the DC capability to view the voice content of the other party in real time when the user is inconvenient to answer the call without specifically customizing and developing the UX interface for the existing mobile phones, and during the viewing process, the called user can restore the call again through an instruction is an urgent problem to be solved.

[0105] Refer toFigure 3A , which is another flowchart of a communication method provided by an embodiment of this application. As Figure 3A shown, it includes:

[0106] 101. The first server receives a call request from the second terminal and initiates a first call request to the first terminal based on this call request.

[0107] In an embodiment of this application, the first server refers to the IMS AS.

[0108] The second terminal is the calling terminal, and the first terminal is the called terminal. For specific descriptions, reference can be made to the relevant descriptions of the aforementioned terminal devices. The calling terminal initiates a call request. The first server receives the call request from the calling terminal and forwards this call request to the called terminal.

[0109] 102. The first terminal receives the first call request from the first server and sends a first message to the first server based on a detected first instruction. The first message is used to indicate rejecting the first call request, and the first instruction is used to reject the call request.

[0110] After the first terminal receives the call request from the second terminal, it starts ringing. At this time, user 1 corresponding to the first terminal is inconvenient to answer and initiates a first instruction to reject the call. After the first terminal detects the first instruction, it indicates to the first server to reject the first call request.

[0111] 103. The first server sends a second call request to the first terminal based on the first message. The second call request includes a customized ringtone signal CRS service.

[0112] The first server detects that the first terminal subscribes to the call assistant service, does not end the call request from the second terminal, but accepts this first call request and initiates a second call request to the first terminal.

[0113] Optionally, before sending the second call request to the first terminal, this method further includes: determining that the number of the second terminal is a preset number.

[0114] That is to say, when the first server detects that the first terminal subscribes to the call assistant service and determines that the number of the second terminal is a preset number, it starts the call assistant service. The preset number can refer to the number of an important contact (even if not available to answer immediately, the message should be answered), such as the numbers of parents or relatives, the number of a leader, etc. Or the preset number can refer to the number of an unknown user (needs to be observed carefully before determining whether to answer), etc.

[0115] The second call request includes customized ringer signals (CRS) (i.e., carrying urn:alert:service:crs). When the first terminal receives the second call request (i.e., in the ringing state), it can view the video from the server side. CRS can be, for example, pictures, recorded or created music, greetings, voices, advertisements, videos, etc.

[0116] Therefore, step 103 has two meanings: (1) The first server applies for a second media resource as the CRS video media resource from the media network element (such as MRP or MF) in the home network of the first terminal; (2) The first server carries the customized ringer signal (linked to the second media resource) in the second call request sent.

[0117] 104. The first terminal maintains the ringing state based on the received second call request.

[0118] After the first terminal receives the second call request, as long as user 1 of the first terminal does not answer the call request, the first terminal maintains the ringing state. In the case where the first terminal maintains the ringing state, playing the CRS video is supported on the terminal interface.

[0119] 105. The first server sends a first notification message to the second terminal through the first media resource, and the first notification message is used to instruct the second terminal to send a message.

[0120] When the first server sends the second call request to the first terminal, the call assistant service has been started. The content of the call assistant service also includes sending a first notification message to the calling terminal (the second terminal) to instruct the calling terminal to send a message.

[0121] The specific process can be: The first server instructs a media network element such as MF to play a voice message through the first media resource to prompt user 2 of the second terminal to leave a message. For example, the voice content is "This is the AI call assistant of user 1. The master is busy and unable to answer now. How can I help you?..."

[0122] Optionally, before the first server instructs the media network element to play a voice message to the second terminal through the first media resource, the first server can also apply for the first media resource for the second terminal from the media network element.

[0123] For step 103 and step 105, there is no obvious sequence. That is, step 103 can be executed first, step 105 can be executed first, or the two steps can be executed simultaneously.

[0124] 106. The first server sends the first message from the second terminal to the first terminal through the second media resource.

[0125] The first server sends the first message information to the first terminal through the second media resource, where the second media resource is linked to the CRS service, that is, the first server plays the first message information through the CRS video. Before playing the first message information through the CRS video, the voice message of the second terminal can be converted into text information and played in the CRS video in the form of subtitles to avoid disturbing the user of the first terminal.

[0126] 107. The first terminal receives the first message information from the second terminal sent through the second media resource and displays the first message information through the CRS video.

[0127] Therefore, the first server can always send media information to the first terminal through the CRS video (media resource). The first message information from the second terminal can also be sent to the first terminal through the CRS video as media information for display. Specifically, it can be displayed in the form of video subtitles or in the form of pictures. Or in the case where the user does not set it, it can also be displayed in the form of voice or (audio) video.

[0128] See Figure 3B , Figure 3B which is a schematic diagram of a mobile phone call interface provided by an embodiment of the present application. As shown in (a) in Figure 3B , when the first terminal receives a second call request from the second terminal, a CRS video is displayed on the mobile phone call interface, which is a video of blessing content. After the first server notifies the second terminal to send message information, the first message information of the second terminal is linked to the CRS video sent to the second terminal through the second media resource. Therefore, as shown in (b) in Figure 3B , the subtitles in the CRS video include the first message information.

[0129] It can be seen that in the embodiment of the present application, through the server (the first server) in the IMS, when the first terminal subscribes to the call assistant service and the CRS service, after the user rejects the call from the second terminal, the call of the second terminal is retained, and a second call request is initiated to the first terminal, and the CRS service is carried in the second call request, so that the user of the first terminal can watch the message information from the first terminal through the CRS video when the first terminal is in the ringing state. This process can provide a call assistant function for the terminal device without additional UX design for the terminal and reduce user operations, obtain the message information of the calling party, and keep the call of the calling end during the process of obtaining the message information, which helps to resume the call between the two parties in real time.

[0130] When possible, the first server may also include the CRS service in the first call request sent, so that the user can obtain the other party's message information during hesitation or waiting without hanging up the phone, so as to determine whether to answer the other party's call. This can further simplify the user operation and improve the communication efficiency. In this process, the conditions for triggering the first server to obtain the message information from the second terminal may include: 1) The waiting time for the first terminal to answer exceeds the preset duration; 2) The number of the second terminal is the preset number; 3) The current time period, etc., or other conditions may also be included, which will not be elaborated here.

[0131] See Figure 3C , Figure 3C which is another flowchart of the communication method provided by the embodiment of the present application. As Figure 3C shown, the method further includes:

[0132] 1001. Based on the detected second instruction, the first terminal sends a second message to the first server, and the second message is used to indicate accepting the second call request, and the second instruction is used to accept the call.

[0133] User 1 can operate the "answer button" on the mobile phone interface to initiate the second instruction for answering the second call request from the first server, that is, answering the call request from the second terminal.

[0134] 1002. The first server receives the second message from the first terminal and establishes a two-way call between the first terminal and the second terminal based on the second message.

[0135] After receiving the second message, the first server determines that User 1 of the first terminal wants to answer the call from the second terminal, so a two-way call between the first terminal and the second terminal is established.

[0136] It can be seen that in the embodiment of the present application, without increasing the UX design of the first terminal, the first terminal can enter the call state with the second terminal in the message answering state, ensuring the convenience and real-time nature of resuming the call.

[0137] Optionally, as Figure 3C shown, the method may further include the following steps:

[0138] 1003. The first server sends the first message information to the second terminal through the first media resource.

[0139] When the media network element receives the first message information from the second terminal, it sends the first message information to the first terminal through the second media resource, and at the same time, the media network element can feedback the first message information to the interface of the second terminal through the first media resource. That is, the first message information sent to the second terminal and the first message information sent to the first terminal are synchronous information.

[0140] This enables the user 2 of the second terminal to know what content of the message has been sent to the user of the first terminal, so as to take subsequent message measures and improve the user experience of the second terminal.

[0141] The above embodiments will be described in detail below in combination with SIP signaling messages.

[0142] Please refer to Figure 4 , Figure 4 which is a flowchart of a specific communication method provided by an embodiment of the present application. As Figure 4 shown, the method includes:

[0143] 1. The calling terminal A initiates a call (INVITE) to the called terminal B.

[0144] The calling terminal A is the aforementioned second terminal, and the called terminal B is the aforementioned first terminal. The call initiated by the terminal A to the terminal B is first transmitted to the IMS AS in the home network of the terminal B (network B), and then forwarded by the IMS AS to the terminal B.

[0145] 2. According to the subscribed calling line identification presentation (CLIP, a service defined by 3GPP, which means that the called terminal can see the calling number of the calling party), the terminal B sees that it is a call from the terminal A.

[0146] Since the user B of the terminal B is unable to answer the call in a special scenario, the user B decides to activate the subscribed "AI assistant" service (i.e., the call assistant service), and the user B directly hangs up the phone without answering the call.

[0147] 3. The called terminal B sends a BYE message to hang up the phone. (The preamble messages such as ringing are omitted in the process)

[0148] 4. The IMS AS in the network B starts the AI call assistant service logic according to the user subscription and the BYE message of the called terminal B hanging up.

[0149] 5. The IMS AS in the network B sends a 200OK message to the calling terminal A to indicate to the calling network A (the home network A of the terminal A) and the calling terminal A that the current call is connected.

[0150] 6. The IMS AS in the network B instructs the IMS media element MRP, etc. to play a sound to prompt the user A of the calling terminal A that the service is in progress, such as "This is the AI call assistant of B. The master is busy and unable to answer now. What can I do for you?...".

[0151] 7. The IMS AS of Network B instructs the IMS media element MRP to use ASR technology to convert the call content of User A of the calling terminal A into text content and display it on terminal A through the video channel. (Optional step)

[0152] 8. The IMS AS of Network B initiates a second call to terminal B. The IMS AS of Network B carries urn:alert:service:crs in the INVITE message, indicating that this call is processed according to the CRS color ringing process.

[0153] The process can be divided into two sub-processes: 8a applying for CRS video media resources and 8b carrying urn:alert:service:crs in the INVITE message.

[0154] 9. The IMS AS of Network B sets the number of the calling terminal A (calling number) as the special service number of the AI call assistant according to the user subscription. (Optional step) This step can be executed before the entire call process (i.e., before step 1) or at this step.

[0155] 10. The called terminal B's mobile phone rings (responding with a 180 Ringring ringing message, indicating that terminal B has rung).

[0156] 11. The called terminal B connects the video color ringing media to the MRP of Network B.

[0157] 12. The IMS AS of Network B instructs the IMS media element MRP to use ASR technology to convert the call content of the calling user A into text content and display it on the mobile phone of B through the video channel.

[0158] At the same time, the IMS AS of Network B instructs the IMS media element MRP to use ASR technology to also display the text content on terminal A through the video channel (optional process). So that the content displayed on terminal A and terminal B maintains relative synchronization with the content spoken by user A.

[0159] 13. The called user B watches the own screen, obtains the importance of the content expressed by user A, decides to answer the call, and user B presses the answer key.

[0160] 14. The called terminal B sends a 200 OK message for answering.

[0161] 15. The IMS AS of Network B initiates a media redirect process to the calling terminal respectively through ReInvite to directly connect the audio and video media of terminal A and terminal B.

[0162] 16. Terminal A and terminal B talk to each other bidirectionally to achieve the called party's call back.

[0163] Optionally, Figures 3A to 3C the first server in Figure 4 may also refer to an over the top (OTT) network server, such as a next generation network (NGN) server, a circuit switching (CS) network server, or a Web real-time communication (WebRTC) server, etc. When the first server is an OTT network server, the corresponding server name and media network element name also change accordingly. Taking the NGN network as an example, the server for controlling signaling interaction is the NGN service version, and the board providing media resources and services is the NGN media resource servers (MRS). That is, the implementation process of the communication method in the NGN network is the same as that in

[0164] except for the difference in the network element name in IMS described above, and the remaining steps are the same, so they will not be elaborated here. Figure 5A , Figure 5A which is a flowchart of a communication method provided by an embodiment of the present application. As Figure 5A shown, the method includes:

[0165] 201. The first server receives a call request from the second terminal, and initiates a first call request to the first terminal based on the call request.

[0166] In the embodiment of the present application, the first server refers to the IMS AS.

[0167] The second terminal is the calling terminal, and the first terminal is the called terminal. For specific descriptions, refer to the relevant descriptions of the foregoing terminal devices. The calling terminal initiates a call request, and the first server receives the call request from the calling terminal and forwards the call request to the called terminal.

[0168] 202. The first terminal receives the first call request from the first server, and sends a first message to the first server based on the detected first instruction. The first message is used to indicate rejecting the first call request, and the first instruction is used to reject the call request.

[0169] After the first terminal receives the call request from the second terminal, it starts to ring. At this time, user 1 corresponding to the first terminal is inconvenient to answer the call and initiates a first instruction to reject the call. After the first terminal detects the first instruction, it indicates to the first server to reject the first call request.

[0170] 203. The first server sends a second call request to the first terminal based on the first message.

[0171] The first server detects that the first terminal has subscribed to the call assistant service. Instead of ending the call request from the second terminal, it accepts the first call request and initiates a second call request to the first terminal.

[0172] Optionally, before sending the second call request to the first terminal, the method further includes: determining that the number of the second terminal is a preset number.

[0173] That is to say, when the first server detects that the first terminal has subscribed to the call assistant service and determines that the number of the second terminal is a preset number, it activates the call assistant service. The preset number can refer to the number of an important contact (even if not available to answer immediately, the message should be answered), such as the number of parents or relatives, the number of a leader, etc. Or the preset number can refer to the number of an unknown user (needs to be observed carefully before deciding whether to answer), etc.

[0174] 204. The first server sends a first notification message to the second terminal through the first media resource, and the first notification message is used to instruct the second terminal to send a message.

[0175] When the first server sends the second call request to the first terminal, it has already activated the call assistant service. The content of the call assistant service also includes sending a first notification message to the calling terminal (the second terminal) to instruct the calling terminal to send a message.

[0176] Specifically, this process can be: the first server instructs media network elements such as the MF to play a voice message through the first media resource to prompt the user 2 of the second terminal to leave a message. For example, the voice content is "This is the AI call assistant of user 1. The master is busy now and cannot answer. What can I do for you?...".

[0177] Optionally, before the first server instructs the media network element to play a voice message to the second terminal through the first media resource, the first server can also apply for the first media resource for the second terminal from the media network element.

[0178] There is no obvious sequence between step 203 and step 204. Step 203 can be executed first, step 204 can be executed first, or the two steps can be executed simultaneously.

[0179] 205. The first terminal receives the second call request from the first server and sends a second message to the first server based on the detected second instruction. The second message is used to indicate acceptance of the second call request, and the second instruction is used to accept the second call request.

[0180] The first terminal receives a second call request from the first server. Based on the call assistant service subscribed by itself (implicitly indicating that the call assistant service has been started), it knows that this call request is used to enter the first connection state, that is, it can listen to the message information (text message or picture message) of the second terminal, but will not receive the voice information of the second terminal. Therefore, user 1 instructs to accept the second call request through the second instruction.

[0181] Alternatively, the second call request can also explicitly indicate that the call assistant service has been started by differentiating the ringing mode of the second call from the first call, the incoming call display content, etc.

[0182] For reference, Figure 5B , Figure 5B which is a schematic diagram of a mobile phone call interface provided by an embodiment of the present application. As shown in (a) of Figure 5B , it is a schematic diagram of the interface when the first terminal receives the second call request, which may include the incoming call number (if there is a note for the number, the note information can also be displayed), as well as the answer key and the reject call key (hang-up key). User 1 can click or slide the answer key to send the second instruction to receive the second call request, and the terminal enters the Figure 5B interface of the first connection state shown in (b) of

[0183] 206. When the first server receives the second message from the first terminal, it establishes the first connection state of the first terminal. The first connection state includes sending media information other than voice information to the first terminal. Correspondingly, the first terminal enters the first connection state with the second terminal.

[0184] The first server receives the second message and learns that user 1 of the first terminal wants to receive the message information from the second terminal. Therefore, it establishes the first connection state between the first terminal and the second terminal. The first connection state means that the first terminal receives the text information from the second terminal, but does not receive the voice information from the second terminal (to avoid being disturbed by the sound). Therefore, the first server applies for a second media resource for the first terminal, and at the same time applies for the media network element to perform automatic speech recognition (ASR) processing on the voice information received from the second terminal, and sends the text information obtained after the ASR processing to the first terminal for display through the second media resource. The second media resource can be a video channel, and the text information is displayed in the form of video subtitles.

[0185] 207. The first server sends the first message from the second terminal to the first terminal through the second media resource.

[0186] 208. The first terminal receives the first message information from the second terminal and displays the first message information through video subtitles.

[0187] The first server has established the first connection state between the first terminal and the second terminal, applied for the second media resource for the first terminal, that is, established a video channel for the first terminal. Therefore, the first server can instruct the media network element to send the text message information after ASR processing to the first terminal through the video channel. The user 1 of the first terminal views the text message by viewing the video subtitles, or can automatically play the text message in the received video subtitles (the first terminal actively displays the first message information or passively triggers the display of the first message information).

[0188] Reference can be made to Figure 5C , Figure 5C a schematic diagram of a message display interface provided by an embodiment of the present application. As Figure 5C shown, the first server sends the text message of the second terminal to the first terminal through the video channel, and the corresponding video display interface is shown on the first terminal, and the text message is displayed in the form of video subtitles.

[0189] It can be seen that in this embodiment, through the IMS server (the first server), when the first terminal subscribes to the call assistant service, the call of the second terminal is retained after the user rejects the call from the second terminal, and a second call request is initiated to the first terminal, so that the user of the first terminal can answer the message information from the second terminal by answering the second call request. This process can provide the call assistant function for the terminal device without additional UX design for the terminal, obtain the message information of the calling party, and keep the calling end in a call state during the process of obtaining the message information, which is helpful for restoring the two-way call in real time.

[0190] Optionally, reference can be made to Figure 5D , Figure 5D another communication method flowchart provided by an embodiment of the present application. This method further includes:

[0191] 2001. When the first terminal detects a third instruction for the first message information, it sends a third message to the first server. The third message is used to request to enter the second connection state between the first terminal and the second terminal. The second connection state is used for two-way call, and the third instruction is used to accept the call.

[0192] The first terminal is already in the first connection state, and there is no connection button on the interface. The user 1 can use a voice instruction as the third instruction to instruct to answer the call from the second terminal. The content of the voice instruction is, for example, "answer the phone". Or the third instruction can also be initiated through a dual tone multi frequency (DTMF) signal (such as 8#).

[0193] In 2002, the first server receives a third message from the first terminal and establishes a two-way call between the first terminal and the second terminal based on the third message. Correspondingly, the first terminal enters a two-way call with the second terminal.

[0194] After the first server receives the third message from the first terminal, it learns that the user 1 of the first terminal wants to answer the call from the second terminal. Then, a two-way call is established (or resumed) for the first terminal and the second terminal. Specifically, it includes initiating a media redirection process to the calling terminal and the called terminal, thereby directly connecting the audio and video media of the first terminal and the second terminal to achieve called back connection.

[0195] It can be seen that in the embodiment of the present application, without increasing the UX design of the first terminal, the first terminal can enter the call state with the second terminal in the message answering state, ensuring the convenience and real-time nature of resuming the call.

[0196] Optionally, as Figure 5D shown, the method may further include the following steps:

[0197] In 2003, the first server sends the first message information to the second terminal through the first media resource.

[0198] When the media network element receives the first message information from the second terminal, it sends the first message information to the first terminal through the second media resource. At the same time, the media network element can feedback the first message information to the interface of the second terminal through the first media resource. That is, the first message information sent to the second terminal and the first message information sent to the first terminal are synchronous information.

[0199] This can enable the user 2 of the second terminal to know what content of the message has been sent to the user of the first terminal. So as to take subsequent message measures. The user experience of the second terminal is improved.

[0200] The above embodiments will be introduced in detail below in combination with SIP signaling messages.

[0201] Please refer to Figure 6 , Figure 6 which is a specific communication method flowchart provided by the embodiment of the present application. As Figure 6 shown, the method includes:

[0202] 1. The calling terminal A initiates a call (INVITE) to the called terminal B.

[0203] 2. According to the calling line identification presentation (CLIP, a service defined by 3GPP, which means that the called terminal can see the calling number of the calling party) subscribed by the terminal B, the terminal B sees that it is a call from the terminal A.

[0204] Since user B of terminal B cannot answer the call in a special scenario, user B decides to activate the subscribed "AI assistant" service (i.e., the call assistant service). User B directly hangs up the phone without answering it.

[0205] 3. The called terminal B sends a BYE message to hang up the call. (The preamble messages such as ringing are omitted in the process)

[0206] 4. The IMS AS of network B starts the AI call assistant service logic according to the user subscription and the BYE message sent by the called terminal B when it hangs up.

[0207] 5. The IMS AS of network B sends a 200OK message to the calling terminal A to indicate to the calling network A (the home network A of terminal A) and the calling terminal A that the current call is connected.

[0208] 6. The IMS AS of network B instructs the IMS media element MRP, etc. to play a sound to prompt user A of the calling terminal A that the service is in progress, such as "This is B's AI call assistant. The master is busy and cannot answer now. How can I help you?...".

[0209] Before instructing MRP, etc. to play a sound, the IMS AS can also first send a media resource request to MRP to obtain the media resources for terminal A.

[0210] 7. The IMS AS of network B instructs the IMS media element MRP to use ASR technology to convert the call content of user A of the calling terminal A into text content and display it on terminal A through the video channel. (Optional step)

[0211] Steps 1 to 7 in this embodiment are the same as the corresponding steps 1 to 7 described above Figure 6 and will not be elaborated here.

[0212] 8. The IMS AS of network B initiates a second call to the called terminal B. According to the assistant service logic started in the fourth step, the assistant service is directly started (i.e., 8 follows message 4). Of course, in the actual development of the service logic, a certain time buffer can be set.

[0213] 9. The IMS AS of network B sets the number of the calling terminal A (the calling number) as the special service number of the AI call assistant according to the user subscription. (Optional step) This step can be executed before the entire call process (i.e., step 1) or at this step.

[0214] Therefore, the second call initiated by the IMS AS of network B based on terminal A can be displayed as an incoming call from the AI call assistant on terminal B.

[0215] 10. The called terminal B rings (responding with a 180 Ringring ringing message, indicating that terminal B is ringing).

[0216] 11. User B of the called terminal B, based on their AI call assistant subscription status, learns that there will be a second ringing experience for this service. At the same time, observing that the calling number is marked as an AI call assistant special service number (it may also not have this marking), decides to answer the call.

[0217] 12. The called terminal B sends a 200 OK message to indicate answering.

[0218] This answering is not a real answer to the call from the calling terminal A, but an answer to the message left by the calling terminal A.

[0219] 13. The IMS AS of network B instructs the IMS media element MRP, etc. to negotiate the video subtitle media channel. At the same time, the IMS AS of network B instructs MRP to detect keywords (voice commands for answering the call) or detect DTMF signals.

[0220] 14. The IMS AS of network B instructs the IMS media element MRP to use ASR technology to convert the call content of the calling user A into text content and display it on the mobile phone of B through the video channel.

[0221] At the same time, the IMS AS of network B instructs the IMS media element MRP to use ASR technology to also display the text content on terminal A through the video channel (optional process). So that the content displayed on terminal A and terminal B remains relatively synchronized with what user A said.

[0222] 15. User B of the called terminal B views their own screen, determines the importance of the content expressed by user A, and decides to answer the call.

[0223] User B says the voice command "answer", or presses the AI call assistant callback DTMF button (such as 8#). For the terminal, whether it is pressing the button or saying "answer", it is sent to the network side through the audio - video channel. For the terminal, this is an existing function of basic calls, so the terminal does not need additional UX design or modification.

[0224] 16. User B uses the voice command "answer" or DTMF button to instruct the media resource server MRP of network B. The MRP of network B determines the user's callback intention based on the keyword "answer" or the AI call assistant callback DTMF button (such as 8#).

[0225] 17. The MRP of network B reports the "called callback" event to the IMS AS of network B.

[0226] 18. The IMS AS of Network B initiates a media redirect process to the calling and called terminals respectively through ReInvite, so as to directly connect the audio and video media of Terminal A and Terminal B.

[0227] 19. Terminal A and Terminal B talk to each other bidirectionally to realize the called party's call back.

[0228] Optionally, Figures 5A to 5D the first server in can also refer to an OTT network server, specifically, for example, an NGN server, a CS network server, or a WebRTC server, etc. When the first server is an OTT network server, the corresponding server name and media network element name also change accordingly. Taking the NGN network as an example, the server for controlling signaling interaction is the NGN service version, and the one providing media resources and services is the NGN media resources server (MRS) board. Please refer to Figure 7 , Figure 7 which is a flowchart of a communication method for an NGN network provided by an embodiment of the present application. As shown in Figure 7 the implementation process of the communication method of the NGN network is only different in the network element name from that of the IMS in the above Figure 7 , and the rest of the steps are the same, so they will not be elaborated here.

[0229] As shown in Figure 8 the structural schematic diagram of the communication device, the present application embodiment also provides a communication device 1200. The communication device 1200 can be a terminal device, or can be used for but not limited to a terminal device. The communication device 1200 includes a transceiver unit 1201 and a processing unit 1202. The transceiver unit 1201 can be or can be deployed in a transceiver, a transceiver antenna, an input / output interface, etc., which can implement the information transceiver function unit or module. The processing unit 1202 can be or can be deployed in a processor. Among them,

[0230] The transceiver unit 1201 is configured to receive a first call request from a first server, and send a first message based on a detected first instruction. The first message is used to indicate rejecting the first call request, and the first instruction is used to reject the call request;

[0231] The transceiver unit 1201 is further configured to receive a second call request from the first server;

[0232] The processing unit 1202 is configured to send a second message to the first server in combination with the transceiver unit 1201 based on a detected second instruction.
