[0095] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0096] IMS Data Channel technology is based on Web Real-Time Communications (WebRTC) technology and uses Session Initiation Protocol (SIP) signaling for control, enabling the establishment of point-to-point and point-to-platform data channels within the IMS network.

[0097] In existing technologies, new call mini-programs have been designed based on IMS Data Channel to provide users with an interactive business experience during calls. However:

[0098] In existing cross-device interconnection scenarios, the underlying layer is based on WiFi Direct, while the application layer transmits proprietary protocols from various manufacturers, making them unable to communicate with each other.

[0099] In existing cross-device interconnection scenarios, the screen displayed on the large screen device is a projected image, which cannot achieve the purpose of interaction.

[0100] The endpoint of the operator's IMS DC (Data Channel) capability is the mobile phone. There is no mobile phone-centric IMS DC network, and the ability of device interconnection is not fully utilized. The new call applet is not designed for device interconnection scenarios.

[0101] To address the aforementioned technical problems, this invention provides a data transmission method, apparatus, device, storage medium, and program product. The method and apparatus are based on the same concept as described in the application. Since the methods and apparatus solve problems based on similar principles, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0102] like Figure 1 The diagram shown is one of the flowcharts illustrating a data transmission method provided in an embodiment of the present invention. This method is applied to a terminal; that is, it is executed by the terminal. The method may include:

[0103] Step 101: Obtain the first mini-program and the second mini-program through the network-side device, wherein the first mini-program is matched with the terminal and the second mini-program is matched with the target device;

[0104] Optionally, the first applet and the second applet are both new call applets. It should be noted that the terminal obtains the second applet through the network side device because a bottom connection channel is established between the terminal and the target device in advance, and the terminal side obtains the second applet matched with the target device through the network side device in a case where it is judged that the target device is connected.

[0105] It should be noted that after the terminal obtains the first applet and the second applet, the terminal displays the first applet, that is, the terminal displays the interactive interface of the first applet.

[0106] Step 102, in a case where a bottom connection channel is established between the terminal and the target device, the second applet is sent to the target device based on the first applet;

[0107] Here, the bottom connection channel is established between the terminal and the target device through a wireless connection mode or a wired connection mode. For example, the bottom connection channel between the terminal and the target device is established through a WiFi connection mode.

[0108] Here, the second applet is sent to the target device based on the first applet, which can be that the second applet is sent to the target device in response to an operation on the first applet. For specific implementation, refer to the subsequent embodiment part.

[0109] Step 103, receiving interactive data of the second applet sent by the target device, and forwarding the interactive data to the network side device.

[0110] Through the above processing, the interconnection and interaction of the new call applet between the devices (here, the terminal and the target device) can be realized, and the interactive experience is improved.

[0111] In an optional embodiment, the step 101 of obtaining the first applet and the second applet through the network side device includes:

[0112] Step 1011, establishing an applet bootstrap data channel (BDC) connection with the network side device;

[0113] After the terminal establishes a call with the network side device, an applet bootstrap data channel (BDC) connection is established with the network side device.

[0114] Step 1012, downloading the first applet and the second applet from the network side device through the BDC connection.

[0115] Specifically, the step 1012 can include:

[0116] 1) sending a request message to the network-side device, the request message being used to request a list of applications;

[0117] Optionally, the request message is a Hypertext Transfer Protocol (HTTP) GET request message.

[0118] 2) receiving the list of applications returned by the network-side device through the BDC connection;

[0119] Optionally, the request message carries a mini-application type, and the list of applications includes applications supporting the mini-application type. It should be noted that the mini-application type can be a mini-application type adapted to various external devices. For example, the mini-application type includes but is not limited to a mini-application type adapted to a television, a mobile phone, a wearable device, and a vehicle-mounted system.

[0120] The request message carrying the mini-application type can be represented by the following example:

[0121] GET

[0122] / applicationlist?begin-index=0&app-num=20&sdkVersion=1.1.0&miniapptype=TV_Phone HTTP / 1.1

[0123] The above example indicates that the mini-application type includes a mini-application type adapted to a television and a mobile phone.

[0124] 3) downloading, from the network-side device, the first mini-application matching the terminal and the second mini-application matching the target device based on the list of applications.

[0125] In an optional embodiment, step 102 of transmitting, based on the first mini-application, the second mini-application to the target device includes:

[0126] Step 1021: receiving a first input of a user to the first mini-application;

[0127] The first input of the user to the interactive interface of the first mini-application is received, and the interactive interface of the first mini-application is displayed on the screen of the terminal. Specifically, the interactive interface of the first mini-application is provided with a “forward” button, and the terminal receives a click input of the user to the “forward” button in the interactive interface of the first mini-application.

[0128] Step 1022: establishing a first application layer connection channel between the terminal and the target device in response to the first input;

[0129] Specifically, in step 1022, the first application layer connection channel between the terminal and the target device is established, including:

[0130] The target device is authenticated.

[0131] After the authentication is passed, the first application layer connection channel between the terminal and the target device is established.

[0132] It should be noted that before the first application layer connection channel between the terminal and the target device is established, the target device is authenticated, which is to ensure the security of the device connected with the terminal. The authentication process can use the standard Stream Control Transmission Protocol (SCTP) / Datagram Transport Layer Security (DTLS) handshake to establish the connection.

[0133] In step 1023, the second applet is sent to the target device through the first application layer connection channel.

[0134] Here, when the cross-device sharing occurs, the connection channel between the terminal and the target device is established to realize the sharing and interaction of the applet (i.e., the terminal forwards the interaction data of the second applet sent by the target device to the network side device).

[0135] In an optional embodiment, before the interaction data is forwarded to the network side device, the method further includes:

[0136] A second application layer connection channel between the terminal and the network side device is established, and the first application layer connection channel between the terminal and the target device and the second application layer connection channel have a mapping relationship.

[0137] It should be noted that the terminal is the center device, the target device is connected, and a local network is formed. The terminal is the only outlet of the local network data. All connection channels on the local network side are mapped to the connection channel between the terminal and the network side device.

[0138] Correspondingly, in step 103, the interaction data is forwarded to the network side device, including:

[0139] The interaction data is forwarded to the network side device through the second application layer connection channel.

[0140] The data transmission method of this invention enables the download of a mini-program between the terminal and the network-side device during a call, and when cross-device sharing occurs, it establishes a connection channel between the terminal and the target device to achieve mini-program sharing and interaction.

[0141] In an optional embodiment, after receiving the interaction data of the second applet sent by the target device, the method of the present invention further includes:

[0142] Start the proxy mode and control the first mini-program to pause use.

[0143] It should be noted that when the terminal starts the proxy mode, the local mini-program, i.e. the first mini-program, is paused and the operation is switched to the target device (such as a large screen device). The target device and the terminal are connected through a data channel, and all data is forwarded to the network side device through the terminal. This enables large-screen interconnection and communication.

[0144] Furthermore, after forwarding the interactive data to the network-side device, the method of the present invention further includes:

[0145] The proxy mode is turned off, and the first mini-program is restored to use.

[0146] It should be noted that the forwarding of interactive data to the network-side device refers to the interactive data required to complete the business. After the business is completed, the terminal closes the proxy mode, the local mini-program (the first mini-program) resumes use, and then the process enters the interaction process between the ordinary terminal and the network-side device.

[0147] It should be noted that the mini-programs described in this embodiment of the invention (including the first mini-program and the second mini-program) have cross-device interconnection capabilities. Specifically, cross-device interconnection can be achieved by adding the following fields to the mini-program, as follows:

[0148] {

[0149] "appid":"ScreenShare", / / Generated by the platform

[0150] "appName":"Screen Sharing", / / defined by the application

[0151] "appIcon":"base64:image…", / / The BASE64 encoded string of the application icon

[0152] "Etag":"4z99yfvurhk01",

[0153] "phase":"INCALL", / / Application activation phase

[0154] "autoload":"FALSE", / / Whether to load automatically. If it is set to load automatically, the terminal will directly request the mini-program from the network to download and execute the program without user intervention.

[0155] "ifWorkWithoutPeerDC":"TRUE",

[0156] "supportScene": "3",

[0157] "qos-hint":"loss=0.0002; latency=300, loss=0.0002; latency=600",

[0158] "DeviceTemplate": "TV" / / Phone: mobile phone, TV: large screen TV, Wear: wearable device, AutoMotive: in-vehicle system, indicating the devices that the mini program is compatible with.

[0159] }

[0160] The bolded parts above are newly added fields.

[0161] The data transmission method of this invention obtains a first mini-program and a second mini-program through a network-side device, wherein the first mini-program is matched with a terminal and the second mini-program is matched with a target device; when an underlying connection channel is established between the terminal and the target device, the second mini-program is sent to the target device based on the first mini-program; the interaction data of the second mini-program sent by the target device is received and the interaction data is forwarded to the network-side device. In this way, the above processing can realize the interconnection and interaction of the new call mini-program across devices, improving the interactive experience.

[0162] like Figure 2 The diagram shown is a second flowchart illustrating the data transmission method provided in an embodiment of the present invention. This method is applied to a target device; that is, the method is executed by the target device. The method may include:

[0163] Step 201: When a low-level connection channel is established between the target device and the terminal, a second mini-program is received from the terminal based on a first mini-program. The first mini-program is matched with the terminal and is obtained by the terminal from the network-side device.

[0164] Step 202: Send the interactive data generated by the second applet to the terminal.

[0165] It should be noted that the methods on the target device side correspond to those on the terminal side. For the specific meanings of some terms and the understanding of the steps involved, please refer to the methods on the terminal side mentioned above. They will not be repeated here.

[0166] In an optional embodiment, the step 201 of receiving the second applet sent by the terminal based on the first applet comprises:

[0167] The step 2011 comprises: in response to the terminal trigger, establishing a first application layer connection channel between the terminal.

[0168] Here, the terminal trigger refers to that the terminal responds to the first input of the first applet by the user. In response to the terminal trigger, an application layer data channel (ADC) negotiation process between the terminal is performed.

[0169] The step 2012 comprises: receiving the second applet sent by the terminal based on the first applet through the first application layer connection channel.

[0170] Here, when the cross-device sharing occurs, the connection channel between the target device and the terminal is established to realize the sharing and interaction of the applet (i.e., the terminal forwards the interaction data of the second applet sent by the target device to the network side device).

[0171] In an optional embodiment, after receiving the second applet sent by the terminal based on the first applet, the method of the present application further comprises:

[0172] In the case that it is determined through analyzing the second applet that the second applet matches the target device, an interaction interface of the second applet is displayed.

[0173] The second input of the user to the interaction interface of the second applet is received.

[0174] In response to the second input, interaction data is generated.

[0175] Through the above processing, the business processing of the new call applet corresponding to the business scenario can be realized, and the interaction data is obtained.

[0176] In an optional embodiment, after sending the interaction data generated by the second applet to the terminal, the method of the present application further comprises:

[0177] The second applet is closed, and the first application layer connection channel is closed.

[0178] It should be noted that after the business of the new call applet corresponding to the business scenario is completed, the target device closes the second applet and closes the first application layer connection channel.

[0179] The data transmission method provided by the embodiment of the application can realize the interconnection and interaction of new call programs between cross-devices and improve the interactive experience.

[0180] As shown in Figure 3 Fig. 3 is a flowchart of a third method for data transmission provided by the embodiment of the application. The method is applied to a network side device. That is, the method is executed by the network side device. The method can include the following steps:

[0181] In step 301, a first program and a second program are provided to a terminal, wherein the first program matches the terminal, and the second program matches a target device.

[0182] It should be understood that before the first program and the second program are provided to the terminal, a bottom-layer connection channel has been established between the terminal and the target device.

[0183] In step 302, interaction data forwarded by the terminal from the target device is received, wherein the interaction data is from the second program.

[0184] It should be noted that the method of the network side device corresponds to the method of the terminal, and the meanings of some terms and the understanding of the steps can be referred to the method of the terminal, which will not be described here.

[0185] In an optional embodiment, step 301 of providing the first program and the second program to the terminal includes the following steps:

[0186] In step 3011, a program guide channel BDC is established with the terminal.

[0187] In step 3012, the first program and the second program are provided to the terminal through the BDC.

[0188] Specifically, step 3012 includes the following steps:

[0189] a) receiving a request message sent by the terminal, wherein the request message is used to request to download an application list;

[0190] Optionally, the request message is an HTTP GET request message.

[0191] b) sending the application list to the terminal through the BDC, wherein the application list includes the first program matching the terminal and the second program matching the target device.

[0192] Optionally, the request message carries an applet type, and the application program list includes an application program supporting the applet type. It should be noted that the applet type can be an applet type adapted to various external devices. For example, the applet type includes but is not limited to: an applet type adapted to a television, a mobile phone, a wearable device, and a vehicle-mounted system.

[0193] In an optional embodiment, before receiving the interaction data forwarded by the terminal from the target device, the method of the application further includes:

[0194] establishing a second application layer connection channel with the terminal;

[0195] Correspondingly, the step 302 of receiving the interaction data forwarded by the terminal from the target device includes:

[0196] receiving the interaction data forwarded by the terminal from the target device through the second application layer connection channel, the first application layer connection channel between the terminal and the target device and the second application layer connection channel having a mapping relationship.

[0197] The data transmission method of the embodiment of the application provides a first applet and a second applet for a terminal, wherein the first applet is matched with the terminal, and the second applet is matched with a target device; and receives interaction data forwarded by the terminal from the target device, the interaction data being from the second applet. In this way, the above processing can realize interconnection and interaction of a new call applet between cross-devices, and improve the interaction experience.

[0198] It should be noted that the operator provides an integrated development environment (IDE) for a new call applet developer, which is used for applet development and adaptation to various external devices. The applet developer selects an applet template when creating a project, as shown in the following table.

[0199] Templates Phone and Tablet Wear OS Television Automotive

[0200] After development, the IDE automatically adds a tag field: DeviceTemplate for the applet. In a call, the terminal and a network side device (platform) complete applet downloading, and establish a DC channel between the terminal and a large screen device when cross-device sharing occurs, which is used for applet sharing and interaction. Taking an interesting call applet as an example, an applet developer develops an applet supporting two devices, Funcall1.zip (Phone) and Funcall2.zip (TV), as shown in Figure 4 , and a specific data transmission method implementation process is as follows:

[0201] The terminal is a center device, connecting a large screen device to form a Local network, and the terminal is the only outlet of the Local network data.

[0202] Step 1: The terminal and the large screen device are connected to establish an IP connection channel, and the underlying connection can be based on WiFi.

[0203] Step 2: The terminal and the network (network side device) call to establish a BDC connection.

[0204] Step 3: The terminal requests the network to download the application list through the BDC.

[0205] It should be noted that if the terminal judges that the large screen device has been connected, the type of the applet can be carried in the HTTP GET request when initiating the download list, for example:

[0206] GET

[0207] / applicationlist?begin-index=0&app-num=20&sdkVersion=1.1.0&miniapptype=TV_Phone HTTP / 1.1

[0208] At this time, the network returns the supported applet types, and the terminal interface only needs to display the Phone type applet.

[0209] Step 4: The terminal displays the Phone type applet as the main applet.

[0210] The terminal simultaneously downloads the applet of the connected device (the large screen device connected by the terminal), such as DeviceTemplate: TV.

[0211] Step 5: The user starts the interesting call applet, and the terminal establishes an ADC connection with the network.

[0212] Step 6: If the user selects the applet to be expanded to the large screen device for display, the local ADC is triggered to be established, the terminal is authenticated with the large screen device, and the ADC is established.

[0213] Specifically, the user can click the "forward" button on the Phone type applet to realize the selection of the applet to be expanded to the large screen device for display.

[0214] The user can click the "forward" button on the Phone type applet, and the terminal triggers the ADC negotiation with the connected device to establish a Local DC channel, which does not negotiate with the network side, and all Local DC channels are mapped to the DC channel connected by the UE to the network. We assume that only one Local DC user data interaction is established, and the authentication process adopts the standard SCTP / DTLS handshake to establish a connection.

[0215] Step 7: The terminal sends a Funcall2 (TV) applet to the large-screen device.

[0216] Step 8: The large-screen device displays after receiving the Funcall2 (TV) applet.

[0217] After receiving the Funcall2 (TV) applet, the large-screen device parses it and displays it if it is a DeviceTemplate: TV. The interaction data of the applet is sent to the terminal through the Local DC.

[0218] Step 9: The terminal starts the Proxy proxy mode, and the local applet Funcall1 (Phone) is suspended. The interaction data of the applet of the large-screen device is forwarded to the network through the terminal.

[0219] Here, the terminal starts the Proxy proxy mode, and the local applet Funcall1 (Phone) is suspended. The operation is switched to the large-screen device for operation. The large-screen device and the terminal are connected through the DC, and the data is forwarded to the network through the terminal.

[0220] Step 10: The large-screen device closes the applet and closes the Local ADC channel.

[0221] Step 11: The terminal closes the Proxy proxy mode, and the local applet Funcall1 is restored.

[0222] That is, if the business is completed, the large-screen device closes the applet and closes the Local ADC channel. The terminal closes the Proxy proxy mode, and the local applet Funcall1 is restored. The subsequent process enters the normal terminal and network interaction process.

[0223] The data transmission method of the application makes full use of the reliability of the operator IMS DC, extends the DC channel, and enables the IMS DC to reach other peripheral devices in addition to mobile terminals. It can also fully solve the experience deficiency of new call applets in multi-screen interaction.
