[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on March 20, 2024, with application number 202410322755.7 and application name “Management Method and Device for Application Data Channels”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to, but not limited to, a method and device for managing an application data channel. Background Art

[0004] In the fifth generation (5G) new calls, based on the existing voice service (VoNR) audio and video calls running in the original 5G new frequency band, the concept of data channel (DC) has been added. By establishing one or more data channels between terminal 1 and terminal 2, various types of data are transmitted to keep synchronized with the audio and video call data.

[0005] Among them, the data channel between terminal 1 and terminal 2 consists of three parts, namely the sub-data channel between terminal 1 and its corresponding application server 1, the sub-data channel between application server 1 and application server 2 corresponding to terminal 2, and the sub-data channel between application server 2 and terminal 2.

[0006] While establishing one or more data channels can effectively expand interactive capabilities beyond audio and video communication, in some scenarios, such as interactive entertainment for families, the state of data channels may change frequently as entertainment programs change.

[0146] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0147] In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. A and B can be singular or plural. In the text description of this application, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0148] The technical solution provided by the embodiment of the present application can be adapted to the management scenario of the application data channel. In the new 5G call, based on the original 5GVoNR audio and video call, the concept of DC is added. By establishing one or more data channels between terminal 1 and terminal 2, various types of data are transmitted, and the data is transmitted synchronously with the audio and video call data. The application data establishment process includes the terminal initiating a request to establish an application data channel to the application server through signaling. The request queries the signaling server whether the terminal supports the establishment of an application data channel. The media function network element receives the instructions from the signaling server and performs subsequent operations related to the application data channel.

[0149] While establishing one or more data channels can effectively expand interactive capabilities beyond audio and video communications, each application data channel operation, including creation and closure, must go through all of the aforementioned network elements to complete the entire process. Furthermore, the signaling must carry all previously negotiated data, placing significant pressure on the application server.

[0150] To reduce the pressure on application servers, an embodiment of the present application provides a method for managing application data channels. After the terminal completes the establishment of an application data channel through an application server and a media function network element, the terminal can directly use the application data channel to operate other application data channels with the first media function network element, without the need for the application server or signaling server to participate, and without the need to carry the full amount of previously negotiated data. The implementation of this solution can reduce the pressure on application servers, reduce the number of related network elements involved in application data channel operations, and speed up the processing rate of the entire process.

[0151] To reduce the pressure on application servers, the present application provides a method for managing application data channels. The following describes the method in detail through several specific embodiments. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0152] FIG1 is a flow chart of a method for managing an application data channel provided in an embodiment of the present application, which is applied to a first terminal. For example, in the embodiment of the application, the first terminal may be a terminal such as a user equipment (UE) that supports VoNR audio and video call functions. For example, referring to FIG1 , the method for managing an application data channel may include:

[0153] S101. Send a request to a first media function network element through a first application data channel. The first application data channel is a data channel between a first terminal and the first media function network element for transmitting requests. The request includes at least one or more operations on a second application data channel.

[0154] The first application data channel is used to transmit requests between the first terminal and the first media function network element. Unlike the first application data channel, in this embodiment of the application, the second application data channel is used to transmit operations between the first terminal and the first media function network element.

[0155] For example, in an embodiment of the present application, the first media function network element may be a distributed computing management function (DCMF) or a media resource function (MRF), etc., and may be specifically set according to actual needs, and the embodiment of the present application is not limited to this.

[0156] For example, in this embodiment of the present application, the first application data channel and one or more second application data channels may be application data channels in an application data channel group (ADC Group). The number of second application data channels may be determined based on the maximum number of application data channels supported by the ADC Group and may be set based on actual needs. This embodiment of the present application does not impose any further restrictions on the number of second application data channels.

[0157] For example, in the embodiment of the present application, ADC Group is implemented by extending the media tag "a=adcgroup:" in the Session Description Protocol (SDP). The specific configuration can be made according to actual needs, and the embodiment of the present application does not limit this.

[0158] The core of establishing an ADC Group through negotiation is to establish a first application data channel. The first application data channel in the ADC Group can be used to uniformly manage multiple second application data channels in the ADC Group. When a second application data channel in the ADC Group changes, a request can be sent to the first media function network element via the first application data channel, with the request including at least one or more operations on the second application data channels. A response related to the second application data channel sent by the first media function network element can then be received via the first application data channel. This effectively alleviates the pressure on the first application server corresponding to the first terminal.

[0159] For example, the first application server may be an Internet Protocol (IP) Multimedia Subsystem (IMS) application server (AS).

[0160] For example, in an embodiment of the present application, the request for at least one or more second application data channels may be one of the following:

[0161] Creation of a second application data channel;

[0162] Closing of the second application data channel;

[0163] collaboration between the first application data channel and the second application data channel;

[0164] Collaboration between second application data channels;

[0165] bandwidth configuration of the second application data channel;

[0166] Quality of Service (QoS) configuration of the second application data channel.

[0167] In this way, the first terminal can request the creation, closing, collaboration, bandwidth configuration, or QoS configuration of one or more second application data channels through the first application data channel without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0168] In addition, in some home scenarios with complex interactions and large data volumes, such as big data, large file transfer, extended reality (XR), and remote assistance, the first terminal requests collaboration between one or more second application data channels through the first application data channel, which can effectively reduce the interaction delay and thus effectively improve the data transmission efficiency.

[0169] For example, in an embodiment of the present application, when the operation is the creation of a second application data channel and / or collaboration between second application data channels, the request may also carry the bandwidth of the second application data channel, quality of service (QoS), etc., which can be set according to actual needs, and the embodiment of the present application is not limited to this.

[0170] It can be understood that in an embodiment of the present application, the request sent to the first media function network element through the first application data channel includes collaboration between the first application data channel and the second application data channel, or collaboration between the second application data channels, that is, collaboration between multiple application data channels, which can be applied to scenarios with complex interactions and large data volumes, such as big data, large file transfer, XR, and remote assistance in home scenarios, and can effectively reduce interaction delays, thereby effectively improving data transmission efficiency.

[0171] For example, in an embodiment of the present application, when a first terminal requests an operation of a second application data channel through a first application data channel, the request can be implemented through a command, each of which may include the requested second application data channel, the protocol supported by the second application data channel, and related protocol parameters. Among them, the protocol supported by the second application data channel may be, for example, the Hypertext Transfer Protocol (HTTP) or the Binary Floor Control Protocol (BFCP), and the related protocol parameters may be parameters required for the data format, such as an encryption algorithm, a secret key, etc.

[0172] For example, in an embodiment of the present application, when the request includes at least one or more second application data channels for the creation of a second application data channel, assuming that the second application data channels to be created can be recorded as application data channel "xr_audio" and application data channel "xr_video", the corresponding pseudo code can be: { "cmd":"create", "dc":["xr_audio","xr_video"],"subprotocol":"http","sub_param":""}

[0173] "create" indicates the operation is a create request, "subprotocol" indicates the subprotocol supported by the application data channel xr_audio and the application data channel xr_video, and "http" and "sub_param" represent two different types of subprotocols.

[0174] In this way, the first terminal requests the creation of one or more second application data channels through the first application data channel without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0175] For example, in an embodiment of the present application, when the request includes at least one or more second application data channels and the operation is to close the second application data channel, assuming that the second application data channels to be closed can be recorded as application data channel "ar_audio" and application data channel "ar_video", the corresponding pseudo code can be: { "cmd":"close", "dc":["ar_audio","ar_video"],"subprotocol":"http","sub_param":""}

[0176] Among them, "close" indicates that the operation is a close operation, "subprotocol" indicates the subprotocol supported by the application data channel "ar_audio" and the application data channel "ar_video", and "sub_param" is the specific subprotocol.

[0177] In this way, the first terminal requests to close one or more second application data channels through the first application data channel without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0178] For example, in an embodiment of the present application, the collaboration between the second application data channels is to transmit different parts of the data through at least two second application data channels.

[0179] Assuming that the second application data channels that need to collaborate can be recorded as application data channels "file_transfer1" and "file_transfer2", the corresponding pseudo code can be:

[0180] In the field, "cooperation" indicates that the operation is a collaborative operation, "subprotocol" indicates the subprotocol supported by application data channels "file_transfer1" and "file_transfer2", "http" is the specific subprotocol, "sub_param" indicates the specific collaborative content, {"start_point":0,"end_point":50} indicates that application data channel "file_transfer1" needs to collaborate to transfer the first 50% of the file, and {"start_point":50,"end_point":100} indicates that application data channel "file_transfer2" needs to collaborate to transfer the second 50% of the file.

[0181] In this way, the first terminal requests to execute collaboration between one or more second application data channels through the first application data channel, without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0182] In addition, in some home scenarios with complex interactions and large data volumes, such as big data, large file transfer, XR, and remote assistance, the first terminal requests collaboration between one or more second application data channels through the first application data channel, which can effectively reduce the interaction delay and thus effectively improve the data transmission efficiency.

[0183] For example, in an embodiment of the present application, when the request includes at least one or more second application data channels, the operation is for configuring the quality of service (QoS) of the second application data channels. Assuming that the second application data channels to be configured can be recorded as application data channels "xr_audio" and "xr_video", the corresponding pseudo code may be:

[0184] "qos_hint" indicates that the operation is a Quality of Service (QoS) configuration, and "subprotocol" indicates the application data channels xr_audio and xr_video. Loss indicates the maximum supported packet loss rate; exceeding this rate may result in data errors. Latency indicates the maximum supported latency; exceeding this rate may result in data errors or a poor user experience.

[0185] It can be understood that in an embodiment of the present application, when configuring the quality of service QoS for the application data channel xr_audio and the application data channel "xr_video", it is possible to first query whether the application data channel "file_transfer1" and the application data channel "file_transfer2" have been established. If not, the application data channel "file_transfer1" and the application data channel "file_transfer2" are established first, and then the application data channel xr_audio and the application data channel "xr_video" are configured with quality of service QoS; if they have been established, the application data channel xr_audio and the application data channel "xr_video" are directly configured with quality of service QoS.

[0186] In this way, the first terminal requests to execute the QoS configuration of one or more second application data channels through the first application data channel, without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0187] For example, in an embodiment of the present application, when the request includes at least one or more second application data channels and is for bandwidth configuration of the second application data channels, assuming that the second application data channels to be configured can be recorded as application data channel "xr_audio" and application data channel "xr_video", the corresponding pseudo code may be:

[0188] "brandwidth" indicates bandwidth configuration, "subprotocol" indicates the application data channel xr_audio and the application data channel xr_video, and AS indicates the maximum receivable bandwidth. For example, if the AS of the first terminal is 500, the second terminal cannot send data at a rate exceeding 500, otherwise the first terminal will discard excess data packets. bw-info is an optional parameter that further refines the AS and facilitates bandwidth negotiation between UEs.

[0189] Among them, Type has three values: sendrecv, which indicates that it is used for both receiving and sending; Sendonly, which indicates that it is used only for sending; recvonly, which indicates that it is used only for receiving; MaxSupBw, which indicates the maximum supported bandwidth value; MaxDesBw, which indicates the maximum desired bandwidth value; MinDesBw, which indicates the minimum desired bandwidth value; and MinSupBW, which indicates the minimum supported bandwidth value.

[0190] For example, the first terminal type: recvonly, MaxSupBw: 200, MaxDesBw: 180, MinDesBw: 100, MinSupBW: 0, indicates that the first terminal can receive a bandwidth between 0-200, but expects it to be between 100-180, thereby ensuring a better experience to a certain extent.

[0191] It can be understood that in the embodiment of the present application, when the bandwidth of the application data channel xr_audio and the application data channel "xr_video" is configured, it is possible to first query whether the application data channel "file_transfer1" and the application data channel "file_transfer2" have been established. If not, the application data channel "file_transfer1" and the application data channel "file_transfer2" are first established, and then the bandwidth of the application data channel xr_audio and the application data channel "xr_video" is configured; if they have been established, the bandwidth of the application data channel xr_audio and the application data channel "xr_video" is directly configured.

[0192] In this way, the first terminal requests bandwidth configuration of one or more second application data channels through the first application data channel without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0193] After the first terminal sends a request to the first media function network element through the first application data channel, the first media function network element may perform an operation including at least one or more second application data channels based on the request, and after the execution is completed, receive a response related to the second application data channel sent by the first media function network element through the first application data channel, that is, perform the following S102:

[0194] S102: Receive a response related to the second application data channel sent by the first media function network element through the first application data channel.

[0195] It can be seen that in an embodiment of the present application, when the terminal request includes at least one or more operations of the second application data channel, a request can be sent to the first media function network element through the first application data channel, and the first application data channel is a data channel for transmitting requests between the first terminal and the first media function network element, and the request includes at least one or more operations of the second application data channel; and a response related to the second application data channel sent by the first media function network element is received through the first application data channel to implement operations on one or more second application data channels, without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0196] Based on the embodiment shown in FIG1 , it is not difficult to see that in this embodiment of the present application, the concepts of an application data channel group (ADC Group) and a first application data channel are proposed. To facilitate understanding of how to negotiate and establish an application data channel group (ADC Group) or a first application data channel in this embodiment of the present application, the embodiment shown in FIG2 is described in detail below.

[0197] FIG2 is a schematic diagram of a process for negotiating and establishing an application data channel group ADC Group or a first application data channel according to an embodiment of the present application. The method is applied to a first terminal. The method may be executed by software and / or hardware devices. For example, referring to FIG2 , the method may include:

[0198] S201. Send a request for establishing an application data channel to a first application server, where the request is used to request to establish an application data channel with a first media function network element.

[0199] For example, the first application server may be an IP Multimedia Subsystem (IMS) application server (AS).

[0200] For example, in the embodiment of the present application, at least one of the establishment request and the establishment response includes information of the ADC group or information of the first application data channel and / or the second application data channel, which can be specifically configured according to actual needs.

[0201] The establishment request and / or the establishment response include information of the first application data channel, the second application data channel and / or the application data channel group; the application data channel group includes the first application data channel and / or the second application data channel, which can be specifically set according to actual needs.

[0202] For example, in an embodiment of the present application, the information of the first application data channel may include: information about the ADC Group, information about the first application data channel, information about the second application data channel, etc. The ADC Group information may be an extended media tag "a=adcgroup:0," where a=adcgroup indicates that the negotiation is for the application data channel group ADC Group, and "0" indicates the first ADC Group. The information of the first application data channel may include an identifier of the first application data channel and the protocol supported by the first application data channel, etc., which may be set based on actual needs. The identifier of the first application data channel also serves as the identifier of the application data channel group ADC Group. The information of the second application data channel may be used to determine the number of second application data channels that the application data channel group ADC Group can support, etc., which may be set based on actual needs.

[0203] Taking the example of an establishment request sent by the first terminal to the first application server including information about the first application data channel and / or the second application data channel, after receiving the establishment request, the first application server can negotiate with the first media function network element to establish the application data channel group ADC Group and / or the first application data channel according to the establishment request including the information about the first application data channel and / or the second application data channel. After the establishment is completed, the first application server sends a corresponding establishment response to the first terminal, that is, executes the following S202.

[0204] S202: Receive an application data channel establishment response sent by the first application server.

[0205] The establishment request and / or the establishment response include information of the first application data channel and / or the second application data channel.

[0206] For example, in an embodiment of the present application, the establishment response may include information about the first application data channel and / or the second application data channel; it may also not include information about the first application data channel and / or the second application data channel, but at least one of the establishment request and the establishment response includes information about the first application data channel and / or the second application data channel, which can be specifically set according to actual needs.

[0207] It can be seen that in the embodiment of the present application, the first terminal sends an establishment request for an application data channel to the first application server, where the establishment request is used to request to establish an application data channel with the first media function network element; and receives an establishment response for the application data channel sent by the first application server; wherein the establishment request and / or establishment response include information of the first application data channel / or the second application data channel, so that the application data channel group ADC Group or the first application data channel can be negotiated and established through the establishment request and the establishment response, so that a request can be subsequently sent to the first media function network element through the first application data channel to implement operations on one or more second application data channels, without the need for full negotiation through the application server, thereby greatly reducing the pressure on the application server.

[0208] In order to facilitate understanding of a management method for an application data channel provided in an embodiment of the present application, the following will take the first terminal and the second terminal as an example, both of which are terminals supporting VoNR audio and video call functions, and describe in detail the management method for the application data channel provided in an embodiment of the present application through a specific embodiment.

[0209] FIG3 is a flow chart of another method for managing an application data channel provided in an embodiment of the present application. For example, referring to FIG3 , the method for managing an application data channel may include:

[0210] S301: A first terminal sends an ADC Group negotiation request to a first application server.

[0211] For example, the ADC Group negotiation request may include an ADC Group identifier label="xr", a protocol supported by the core application data channel coresubprotocol="json", and a maximum number of second application data channels that the ADC Group can support end_pointdc="20".

[0212] S302: The first application server sends an ADC Group negotiation request to the second application server corresponding to the second terminal.

[0213] For example, in an embodiment of the present application, before the first application server sends an ADC Group negotiation request to the second application server, it may also request DC management control from the first capability network element to determine whether DC is supported, whether it is a bilateral DC, etc., and then send an ADC Group negotiation request to the second application server.

[0214] S303: The second application server sends an ADC Group negotiation request to the second terminal.

[0215] For example, in an embodiment of the present application, before the second application server sends an ADC Group negotiation request to the second terminal, it may also request DC management control from the second capability network element to determine whether DC is supported, whether it is bilateral DC, etc., and then send an ADC Group negotiation request to the second terminal.

[0216] S304: The second terminal determines to establish an ADC Group and a core application data channel based on the ADC Group negotiation request, and determines a maximum number of second application data channels that the ADC Group can support.

[0217] S305: The second terminal sends an ADC Group negotiation response to the second application server.

[0218] For example, in an embodiment of the present application, the ADC Group negotiation response may include the ADC Group identifier label="xr", the protocol coresubprotocol supported by the core application data channel="json", and the maximum number of second application data channels supported by the ADC Group maxdc="6", which means that the ADC Group negotiation is successful, but the maximum number of second application data channels supported by the ADC Group is reduced to 6.

[0219] S306. The second application server sends an update instruction to the second media function network element, so that the second media function network element updates the DC information and allocates the ADC Group and the core application data channel.

[0220] It should be noted that if the second terminal is a terminal that does not support the VoNR audio and video call function, such as a smart TV, a smart set-top box, a speaker, a doorbell or door lock, etc., the second application server can directly execute the following S307 after receiving the ADC Group negotiation response sent by the second terminal, and send an ADC Group negotiation response to the first application server.

[0221] S307: The second application server sends an ADC Group negotiation response to the first application server.

[0222] It can be understood that in the embodiment of the present application, there is no order between S306 and S307. S306 can be executed first and then S307; S307 can also be executed first and then S306; of course, S306 and S307 can also be executed at the same time. The specific settings can be made according to actual needs. Here, the embodiment of the present application is only illustrated by taking the example of executing S306 first and then executing S307, but it does not mean that the embodiment of the present application is limited to this.

[0223] S308. The first application server sends an update instruction to the first media function network element, so that the first media function network element updates DC information and allocates an ADC Group and a core application data channel.

[0224] S309: The first application server sends an ADC Group negotiation response to the first terminal.

[0225] It can be understood that in the embodiment of the present application, there is no order between S308 and S309. S308 can be executed first and then S309; ​​S309 can also be executed first and then S308. Of course, S308 and S309 can also be executed at the same time. The specific settings can be made according to actual needs. Here, the embodiment of the present application is only illustrated by taking the example of executing S308 first and then executing S309, but it does not mean that the embodiment of the present application is limited to this.

[0226] S310: The first terminal establishes a data channel between the ADC Group and the core application based on the ADC Group negotiation response.

[0227] Among them, the core application data channel includes the first application data channel between the first terminal and the first media function network element, the application data channel between the first media function network element and the second media function network element, and the application data channel between the second media function network element and the second terminal.

[0228] It can be understood that in the embodiment of the present application, the application data channel between the first media function network element and the second media function network element, and the application data channel between the second media function network element and the second terminal are similar to the first application data channel. The application data channel between the first media function network element and the second media function network element is used to transmit requests between the first media function network element and the second media function network element; the application data channel between the second media function network element and the second terminal is used to transmit requests between the second media function network element and the second terminal.

[0229] Based on the above steps S301-S310, the first terminal and the second terminal complete the negotiation and establish the ADC Group and the core application data channel. Subsequently, the application data channel can be managed through the core application data channel in the ADC Group. The application data channel management process can be described in detail in the embodiment shown in FIG. 4 below.

[0230] FIG4 is a flow chart of a management process of an application data channel provided in an embodiment of the present application. For example, as shown in FIG4 , the management process of the application data channel may include:

[0231] S401. A first terminal sends a request to a first media function network element through a first application data channel.

[0232] The request at least includes one or more operations of the second application data channel.

[0233] For example, in the embodiment of the present application, the operation is one of the following:

[0234] Creation of a second application data channel;

[0235] Closing of the second application data channel;

[0236] collaboration between the first application data channel and the second application data channel;

[0237] Collaboration between second application data channels;

[0238] bandwidth configuration of the second application data channel;

[0239] Quality of Service (QoS) configuration of the second application data channel.

[0240] For example, in the case where the operation is to create a second application data channel, the first terminal may send a creation request for the second application data channel to the second terminal through the core application data channel; the second terminal creates the second application data channel based on the creation request; and sends a creation response to the first terminal; the first terminal creates the second application data channel based on the creation response.

[0241] For example, in the case where the operation is to close the second application data channel, the first terminal may send a closing request for the second application data channel to the second terminal through the core application data channel; the second terminal closes the second application data channel based on the creation request; and sends a closing response to the first terminal; the first terminal closes the second application data channel based on the creation response.

[0242] For example, when the operation is collaboration between the second application data channels, it can be applied to scenarios with complex interactions and large data volumes, such as large file transfer, XR, and remote assistance. The first terminal sends a collaboration request between the second application data channels to the second terminal through the core application data channel; assuming that the collaboration request includes the identifiers of the application data channel "file_transfer1" and the application data channel "file_transfer2", the content that the application data channel "file_transfer1" needs to collaborate on is: {"start_point":0,"end_point":50}; the content that the application data channel "file_transfer2" needs to collaborate on is: {"start_point":50,"end_point":100}; based on the collaboration request, the second terminal queries whether the application data channel "file_transfer1" and the application data channel "file_transfer2" have been established. If not, it first establishes the application data channel "file_transfer1". _transfer1" and application data channel "file_transfer2"; if they have been established, based on the collaboration request, it is determined that the first half of the file can be received through the application data channel "file_transfer1"; and it is determined that the second half of the file can be received through the application data channel "file_transfer2"; the second terminal sends a collaboration response to the first terminal; based on the collaboration response, the first terminal sends the first half of the file through the application data channel "file_transfer1"; and sends the second half of the file through the application data channel "file_transfer2"; the second terminal receives the first half of the file through the application data channel "file_transfer1"; and receives the second half of the file through the application data channel "file_transfer2", and writes the received file to the corresponding position.

[0243] For example, in the case of operating bandwidth configuration for the second application data channel, the first terminal may send a bandwidth configuration request for the second application data channel to the second terminal through the core application data channel; the second terminal performs bandwidth configuration for the second application data channel based on the bandwidth configuration request for the second application data channel; and sends a bandwidth configuration response for the second application data channel to the first terminal; the first terminal performs bandwidth configuration for the second application data channel based on the bandwidth configuration response for the second application data channel.

[0244] For example, in the case of operating the quality of service QoS configuration for the second application data channel, the first terminal can send a quality of service QoS configuration request for the second application data channel to the second terminal through the core application data channel; the second terminal performs quality of service QoS configuration for the second application data channel based on the quality of service QoS configuration request; and sends a quality of service QoS configuration response for the second application data channel to the first terminal; the first terminal performs quality of service QoS configuration for the second application data channel based on the quality of service QoS configuration response of the second application data channel.

[0245] S402. The first media function network element sends a request to the second media function network element through the application data channel between the first media function network element and the second media function network element.

[0246] S403. The second media function network element sends a request to the second terminal through the application data channel between the second media function network element and the second terminal.

[0247] It should be noted that if the second terminal is a terminal that does not support the VoNR audio and video call function, S402 and S403 can be replaced by: the first media function network element sends a request to the second application server through the application data channel between it and the second application server, so that the second application server sends a request to the second terminal through the application data channel between it and the second terminal.

[0248] S404: The second terminal updates the status of the second application data channel in the ADC Group based on the request.

[0249] The status of the second application data channel, for example, creation status, closing status, collaboration status, etc.

[0250] S405. The second terminal sends a response to the second media function network element through the application data channel between the second terminal and the second media function network element.

[0251] S406. The second media function network element updates the status of the requested second application data channel based on the response.

[0252] S407. The second media function network element sends a response to the first media function network element through the application data channel between the second media function network element and the first media function network element.

[0253] It can be understood that in the embodiment of the present application, there is no order between S406 and S407. S406 can be executed first and then S407; S407 can also be executed first and then S406; of course, S406 and S407 can also be executed at the same time. The specific settings can be made according to actual needs. Here, the embodiment of the present application is only illustrated by taking the example of executing S406 first and then executing S407, but it does not mean that the embodiment of the present application is limited to this.

[0254] It should be noted that if the second terminal is a terminal that does not support the VoNR audio and video call function, S405-S407 can be replaced by: the second terminal sends a response to the second application server through the application data channel between it and the second application server element, so that the second application server sends a response to the first media function network element through the application data channel between it and the first media function network element.

[0255] S408. The first media function network element updates the status of the requested second application data channel based on the response.

[0256] S409. The first media function network element sends a response to the first terminal through the first application data channel.

[0257] It can be understood that in the embodiment of the present application, there is no order between S408 and S409. S408 can be executed first and then S409; S409 can also be executed first and then S408. Of course, S408 and S409 can also be executed at the same time. The specific settings can be made according to actual needs. Here, the embodiment of the present application is only illustrated by taking the example of executing S408 first and then executing S409, but it does not mean that the embodiment of the present application is limited to this.

[0258] S410: The first terminal updates the status of the second application data channel in the ADC Group based on the request.

[0259] Based on the above S401-S410, the first terminal can operate the second application data channel with the second terminal through the first application data channel without full negotiation through the application server, thereby greatly reducing the pressure on the application server.
