Description

BACKGROUND OF THE INVENTION

Field of the Invention

This application pertains to the field of communication technologies, and particularly relates to a data processing method, a terminal, and a network-side device.

Description of Related Art

Usually, two communication parties can make an augmented reality (AR) call through a data channel (DC). For example, a network-side device establishes an indirect AR channel for the two communication parties, so that the two communication parties can implement the AR call. However, the AR call needs to be rendered, that is, media description information is rendered into a 3D image through a rendering process. Because the media description information itself is small, but a rendered file is large, and the rendering requires a large amount of computation, AR call efficiency of a terminal is low.

A data processing method provided in the embodiments of this application is hereinafter described in detail by using some embodiments and application scenarios thereof with reference to the accompanying drawings.

An AR technology is a technology that skillfully integrates virtual information with the real world. The AR technology extensively uses multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing, and other technical means to simulate/emulate and then apply computer-generated virtual information such as a text, an image, a three-dimensional model, music, and a video to the real world. The two types of information complement each other, thereby implementing “augmentation” of the real world.

The 3rd Generation Partnership Project (3GPP) protocol introduces a mechanism for establishing a data channel during a call. An additional service, such as AR communication, screen sharing, location sharing, or file transfer, may be performed during the call through the DC, thereby bringing better experience to a user. Different services correspond to different DC applications. For ease of use by the user, a DC application may be downloaded dynamically during the call, and does not need to be installed on a terminal in advance. For example, AR communication corresponds to an AR application, and the AR application may be downloaded dynamically during the call.

If two communication parties need to enable an application, the two communication parties should dynamically download the application from a DC server and establish a corresponding application DC for the application. Different applications correspond to different quality of service (QOS) requirements. For example, the AR application requires a low latency and a high throughput, and a screen sharing application requires good real-time performance. Generally, for each application, an application DC corresponding to the application needs to be established.

An AR call integrates a call technology with the AR technology, thereby bringing better experience to a user. Generally, two communication parties may make an AR call through a DC. For example, a network-side device establishes a direct AR data channel or an indirect AR data channel for the two communication parties, so that the two communication parties can use this data channel to implement the AR call. The direct AR data channel means that the AR call between the two communication parties does not require the network-side device to participate in AR media processing, such as rendering processing. The indirect AR data channel means that the AR call between the two communication parties requires the network-side device to participate in AR media processing, such as rendering processing.

Currently, there are two processing manners for the AR call based on the data channel:

• • Manner 1: A terminal performs rendering locally.
  • Manner 2: The network-side device performs rendering and sends a rendered file to the terminal for displaying.

The rendering is to render media description information into a 3D image through a rendering process. The media description information itself is small, but the rendered file is large, and the rendering requires a large amount of computation.

An advantage of manner 1 is that an amount of information transmitted by the network-side device is small, and that a requirement on network signal quality is not high. A disadvantage of manner 1 is that a local amount of computation on the terminal is large, and that requirements on terminal performance and battery power are high.

An advantage of manner 2 is that requirements on an amount of computation and battery power of the terminal are low. A disadvantage of manner 2 is that an amount of information transmitted by the network-side device is large, and that a requirement on network signal quality is high.

Neither manner 1 nor manner 2 can properly resolve a problem of the AR call. For example, when power of the terminal is insufficient, it is necessary to reduce the amount of computation of AR and increase a standby time; or when network signal quality of the terminal is poor, computation is performed locally on the terminal as much as possible to improve fluency of the AR call. Therefore, a manner in which the network-side device determines the AR data channel based on a capability of the terminal is not flexible enough, and may not meet requirements of the terminal. As a result, AR call efficiency of the terminal is low.

It should be noted that although AR is used as an example for description in this application, the solution of this application may also be used for applications such as virtual reality (VR) and extended reality (XR) that need to be processed separately by the terminal and the network side.

An embodiment of this application provides a data processing method. FIG. 2 is a flowchart of a data processing method according to an embodiment of this application. As shown in FIG. 2, the data processing method provided in this embodiment of this application includes the following steps 101 to 105.

Step 101: A second network-side device sends a first result to a terminal and a first network-side device.

The first result includes a processing load obtained after a first processing load is confirmed or modified by the second network-side device, and the first processing load is an amount of data processing load performed by the terminal or the first network-side device as requested by the terminal.

It should be noted that this application is described by assuming that the first network-side device and the second network-side device are two independent network-side devices. Alternatively, the first network-side device and the second network-side device may be a same network-side device. In this case, interaction between the first network-side device and the second network-side device is internal interaction of the network-side device.

Optionally, in this embodiment of this application, the first network-side device is configured to control a data channel, and the second network-side device is configured to transmit the data channel. In other words, the first network-side device performs control-related operations, and the second network-side device performs transmission-related operations.

Optionally, in this embodiment of this application, the second network-side device may first send the first result to the terminal, and then send the first result to the first network-side device; or the second network-side device may first send the first result to the first network-side device, and then send the first result to the terminal; or the second network-side device may simultaneously send the first result to the terminal and the first network-side device. This may be determined based on an actual usage requirement, and is not limited in this embodiment of this application.

Step 102: The first network-side device processes data based on the first result to obtain first data.

Step 103: The first network-side device sends the first data to the terminal.

Optionally, in this embodiment of this application, a feasible implementation is: in a case that a first data channel is established between the terminal and the first network-side device, the first network-side device may send the first data, that is, the data processed by the first network-side device, to the terminal through the first data channel, and the terminal may process the first data based on the first result, that is, the processing load obtained after the processing load requested by the terminal is confirmed or modified by the second network-side device, to obtain final data.

Optionally, in this implementation, the first network-side device may be a DC media entity, and the second network-side device may be a DC server. The first network-side device and the second network-side device may also be other network elements with the same function or of the same type, which is not limited in this embodiment of this application.

It may be understood that the first data channel is used for the first network-side device to transmit the data processed by the first network-side device to the terminal, and that the terminal processes the data to obtain the final data.

Optionally, in this embodiment of this application, another feasible implementation is: in a case that a first data channel is established between the terminal and a third network-side device, the third network-side device may send the first data to the terminal through the first data channel, where the first data includes processed by the first network-side device and then sent to the third network-side device. The terminal may process the first data based on the first result, that is, the processing load obtained after the processing load requested by the terminal is confirmed or modified by the second network-side device, to obtain the final data.

Optionally, in this implementation, the first network-side device may be a data processing entity, the second network-side device may be a DC server, and the third network-side device may be a DC media entity. Using AR as an example, the first network-side device is configured to render AR media, and the first network-side device may be AR media function. The first network-side device, the second network-side device, and the third network-side device may also be other network elements with the same function or of the same type, which is not limited in this embodiment of this application.

It may be understood that the first data channel is used for the third network-side device to transmit the data processed by the first network-side device to the terminal, and that the terminal processes the data to obtain the final data.

Optionally, in this embodiment of this application, the DC media entity is a network-side device configured to provide a transmission function for the data channel, and may also be referred to as a data channel service media (DCS-M) plane entity, a data channel media function (DCMF), a multimedia resource function controller (MRFC), a multimedia resource function processor (MRFP), or the like. The DC server is a network-side device that provides a control function for the data channel, and may also be referred to as a data channel service control (DCS-C) plane entity, a data channel server (DChS), a data channel control function (DCCF), a data channel signaling function (DCSF), or the like.

It should be noted that for the description of the first data channel, details are described in the following embodiment and not described herein.

Optionally, in this embodiment of this application, the foregoing processing may be rendering processing, such as distributed rendering, or may be any other possible processing, such as media encoding and decoding, data computation, and data storage. This may be determined based on an actual usage requirement, and is not limited in this embodiment of this application.

Optionally, in this embodiment of this application, the first data includes data obtained after the network-side device renders data based on the first result.

Step 104: The terminal receives the first data through the first data channel.

Step 105: The terminal processes the first data based on the first result to obtain the final data.

Optionally, in this embodiment of this application, the first result may include the processing load obtained after the first processing load is confirmed by the second network-side device, that is, the first result is the first processing load; or the first result includes the processing load obtained after the first processing load is modified by the second network-side device, that is, the first result is the processing load obtained after the first processing load is modified or a second processing load generated based on the first processing load.

Optionally, in this embodiment of this application, the first processing load is the amount of data processing performed by the terminal as requested by the terminal; or the first processing load is the amount of data processing performed by the first network-side device as requested by the terminal.

It should be noted that, because a total data processing load is fixed, a sum of a data processing load of the terminal and a data processing load of the first network-side device is equal to the total processing load. In other words, the data processing load of the first network-side device is also determined once the terminal determines the data processing load of the terminal. Therefore, the data processing load of the terminal and the data processing load of the first network-side device are equivalent and may be derived from each other.

Optionally, in this embodiment of this application, the first processing load may indicate a data processing capability of the terminal.

Optionally, in this embodiment of this application, the first data includes data obtained after the first network-side device renders data based on the first result. The foregoing step 103 may be implemented by the following step 103a.

Step 103a: The terminal renders the first data based on the first result to obtain the final data.

It may be understood that an implementation of this application is: the first network-side device may render the data based on the first result, the first network-side device may send the rendered data to the terminal through the first data channel, and the terminal may render the rendered data again based on the first result to obtain the final data.

It may be understood that another implementation of this application is: the third network-side device receives the data rendered by the first network-side device based on the first result, the third network-side device may send the rendered data to the terminal through the first data channel, and the terminal may render the rendered data again based on the first result to obtain the final data.

It should be noted that the foregoing data processing process may be understood as: the network-side device may determine the data processing load of the terminal and the data processing load of the network-side device separately based on the processing load requested by the terminal. In the data processing process, the network-side device may process a part of the entire data, and then the terminal may reprocess the data processed by the network-side device, that is, process another part of the entire data, so that the terminal and the network-side device can respectively process a part of the entire data to obtain the final data.

It should be noted that steps 101 to 105 are described by assuming that the terminal receives data. A case of sending data by the terminal is similar to a case of receiving data by the terminal. The terminal processes the data based on the first result to obtain the first data; the terminal sends the first data to the network-side device through the first data channel; and the network-side device processes the first data based on the first result to obtain the final data. For the case of sending data by the terminal, a method for obtaining the first result is the same as a method for obtaining the first result in the case of receiving data by the terminal. Therefore, the case of sending data by the terminal and the case of receiving data by the terminal are the same, except that initial data processing entities and entities obtaining the final result are different. To simplify the description, it is still assumed in the subsequent description that the terminal receives data. Correspondingly, the case of sending data by the terminal also falls within the protection scope of the present application. Details are not described again.

In the data processing method provided in this embodiment of this application, the terminal may receive the first data (that is, the data processed by the first network-side device) through the first data channel; and the terminal may process the first data based on the first result (that is, the processing load obtained after the processing load requested by the terminal is confirmed or modified by the second network-side device) to obtain the final data. According to this solution, the second network-side device may determine the processing load of the terminal and the processing load of the first network-side device based on the processing load requested by the terminal, and the terminal may reprocess, based on the processing load, the data processed by the first network-side device, that is, the terminal and the first network-side device respectively process a part of the data, thereby avoiding a problem that the terminal needs a large amount of computation for processing the entire data alone or a problem that the network-side device needs to consume a large quantity of network resources for processing the entire data alone, and improving AR call efficiency of the terminal.

Optionally, in this embodiment of this application, the data processing method provided in this embodiment of this application further includes the following steps 201 to 206.

Step 201: The terminal sends a first message.

In this embodiment of this application, the first message is used to request to modify the data processing load of the terminal or the first network-side device to the first processing load.

Optionally, in this embodiment of this application, before step 103 (the first network-side device sends the first data to the terminal), the terminal may send the first message.

Optionally, in this embodiment of this application, the first message is a session initiation protocol (SIP) message, and a session description protocol (SDP) of the SIP message includes the first processing load. Alternatively, the first message is a hypertext transfer protocol (HTTP) message, and the HTTP message includes the first processing load.

Optionally, in this embodiment of this application, the terminal may request to modify the data processing load of the terminal to the first processing load; or the terminal may request to modify the data processing load of the first network-side device to the first processing load.

Optionally, in this embodiment of this application, the foregoing step 201 may be implemented by the following step 201a or step 201b.

Step 201a: The terminal sends the first message through the first data channel.

In this embodiment of this application, the first data channel is an application data channel.

Step 201b: The terminal sends the first message through a bootstrap data channel.

It may be understood that the second network-side device receives the first message through the application data channel; or the second network-side device receives the first message through the bootstrap data channel.

For example, the terminal may send the first message to the DC server through the bootstrap DC.

Optionally, in this embodiment of this application, the terminal may also send the first message to the DC media entity through the application DC.

Optionally, in this embodiment of this application, in one implementation, the first message includes first status information of the terminal; and the second network-side device determines the first result based on the first status information. In another implementation, the terminal determines the first processing load based on the first status information of the terminal; and the second network-side device determines the first result based on the processing load requested by the terminal.

Optionally, in this embodiment of this application, the data processing method provided in this embodiment of this application further includes the following step 301.

Step 301: The terminal determines the first processing load based on the first status information of the terminal.

The first status information includes at least one of the following: battery usage, network signal information, usage of computing resources, memory usage, temperature information, capability information of the terminal, or terminal model information.

Optionally, in this embodiment of this application, the first status information of the terminal is used to describe a current status of the terminal, which may also be understood as current performance of the terminal.

The battery usage is used to indicate current used or remaining battery power. It may be indicated by a numerical value, a relative value, or a percentage. For example, total power of the terminal is 4000 mAh, 2000 mAh of the power has been used, and the remaining power is 2000 mAh; or 30% of the power has been used, and the remaining power is 70%.

The network signal information is used to indicate quality of a current signal. For a 5G, 4G, or 3G network, the network signal information may be indicated by one or a combination of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), a received signal strength indicator (RSSI), and a signal to interference plus noise ratio (SINR).

The usage of computing resources is used to describe computing resources currently used by the terminal or remaining computing resources of the terminal. It may be indicated by a numerical value, a relative value, or a percentage. For example, the remaining computing resources are 30%.

The memory usage is used to describe memory resources currently used by the terminal or remaining memory resources of the terminal. It may be indicated by a numerical value, a relative value, or a percentage. For example, remaining memory is 30%.

The temperature information is used to describe a current temperature of the terminal. For example, for a terminal with an excessively high temperature, it is necessary to reduce an amount of computation, to reduce the temperature.

The capability information of the terminal includes a computing capability, a storage capability, a service processing capability, and the like. The service processing capability includes a capability of performing a service, such as a capability of rendering an AR service.

In a case of a terminal with a low capability, such as a terminal with a low price or a terminal having a processor with poor performance inside the terminal, the terminal cannot process all AR rendering services but requires the help of the network-side device.

The capability information of the terminal may be a simple indication of high, medium, or low; or may be a parameter, such as an amount of computation that can be performed per second.

The terminal model information may be grade information of the terminal, such as a high-end terminal, a mid-range terminal, or a low-end terminal; or may be product model information of the terminal.

Optionally, in this embodiment of this application, before step 201 (the terminal sends the first message), the terminal may determine the first processing load based on the first status information.

Optionally, in this embodiment of this application, the first processing load includes at least one of the following:

• • a ratio of data processing by the terminal or the first network-side device; or
  • task allocation for data processing by the terminal or the first network-side device.

Optionally, in this embodiment of this application, the task allocation for data processing by the terminal or the first network-side device may include a description of the task allocation for data processing by the terminal or the first network-side device, a description of workload allocation for data processing by the terminal or the first network-side device, or the like.

For example, a ratio (percentage) of data processing between the terminal and the first network-side device is: 20%: 80%, which may be understood as: the terminal processes 20% of the total workload, and the first network-side device processes 80% of the total workload.

For example, the task allocation for data processing between the terminal and the first network-side device is as follows: Using rendering as an example, the total work includes establishing a spatial map, rendering scenes, establishing virtual human models, and establishing three-dimensional object models (virtual human models and 3D object models according to the field of view, posture, position). The terminal may indicate that the terminal is responsible for establishing the spatial map and rendering the scenes, and that the first network-side device is responsible for establishing the virtual human models and establishing the three-dimensional object models. The terminal may indicate only its own task, or only a task of the first network-side device, or both its own task and a task of the first network-side device.

For example, the following content is carried in SDP information to carry the task allocation for data processing by the terminal:

• • m=application 52718 UDP/DTLS/SCTP webrtc-data channel;

  • ‘a=dcmap: 7216 max-retr=5; label=“low loss”’ represents the application DC, and the stream ID is 7216;
  • “a=3gpp-qos-hint: loss-0.01; latency=100” is used to describe a start attribute of the application DC, loss represents a packet loss rate, and latency represents a latency, in units of ms;

Optionally, in this embodiment of this application, the second status information of the first network-side device is used to describe the current status of the first network-side device, which may also be understood as current performance of the first network-side device.

The load information of the first network-side device is used to indicate the current load status of the first network-side device. It may be indicated by a numerical value, a relative value, or a percentage. For example, remaining load is 30%.

Optionally, in this embodiment of this application, the first result may indicate whether to agree to the processing load of the terminal or the processing load of the first network-side device.

In this embodiment of this application, because the second network-side device may determine the processing load of the terminal and the processing load of the first network-side device based on the processing load requested by the terminal, the problem that the terminal or the network-side device needs a large amount of computation for processing the entire data alone is avoided, and flexibility of data processing is improved.

Optionally, by using three cases, the following describes a process of establishing the first data channel between the terminal and the first network-side device in this embodiment of this application. In the first case, as a calling device, the terminal may send a request message to the second network-side device to request establishment of an indirect data channel, and in a case that a confirmation message is received, the terminal may establish the indirect data channel with the first network-side device. In the second case, as a called device, the terminal may send a request message to the second network-side device to request establishment of an indirect data channel, and in a case that a confirmation message is received, the terminal may establish the indirect data channel with the first network-side device.

Optionally, in this embodiment of this application, the data processing method provided in this embodiment of this application further includes the following steps 501 to 505.

Step 501: The terminal sends a third message.

In this embodiment of this application, the third message carries first information, and the first information is used to request or indicate establishment of an indirect data channel or establishment of a data channel in which a network-side device participates.

When the first information is the indirect indication, the network-side device autonomously determines, based on the first information, that it is necessary to establish the indirect data channel or the data channel in which the network-side device participates. For example, when the first information is capability information of the terminal, the network-side device determines that a capability of the terminal is low, thereby determining that it is necessary to establish the indirect data channel or introduce the network-side device into the data channel to help the terminal perform rendering processing.

Optionally, in this embodiment of this application, the indirect data channel or the data channel in which the network-side device participates is an application data channel. In other words, the first data channel in this embodiment of this application is an application data channel.

Optionally, in this embodiment of this application, before step 103 (the first network-side device sends the first data to the terminal), the terminal may send the third message.

Optionally, in this embodiment of this application, the third message is a SIP message. SDP information of the SIP message carries the first information; or a message header of the SIP message carries the first information.

  • b=AS: 500;
  • a=max-message-size: 1024;
  • a=sctp-port: 5000;
  • a=dcmap: 10 subprotocol=“http”;
  • a=dcmap: 7216 max-retr=5; label=“low loss”;
  • a=media path: indirect.
  • where a=media path: indirect indicates establishment of an indirect data channel.

It should be noted that for descriptions of row m, row b, and row a, reference may be made to the related description of the foregoing step 301. Details are not described herein again.

Optionally, in this embodiment of this application, when the message header of the SIP message carries the first information, the first information is carried by a media feature tag or a function feature capability (Feature-Caps) of the SIP message.

Step 502: The second network-side device receives the third message.

Step 503: The second network-side device sends a fourth message.

Optionally, in this embodiment of this application, the fourth message is a confirmation message. Alternatively, the fourth message carries an SDP answer, and the SDP answer is used to establish the indirect data channel.

Optionally, in this embodiment of this application, the fourth message may be a 200 OK message, a 183 message, a 180 message, or the like. This may be determined based on an actual usage requirement, and is not limited in this embodiment of this application.

Step 504: The terminal receives the fourth message.

Step 505: The terminal establishes the first data channel based on the fourth message.

In this embodiment of this application, the terminal may send the third message to the second network-side device to request establishment of the indirect data channel; the second network-side device may reply to the terminal with the fourth message; and the terminal may establish the indirect data channel with the first network-side device based on the fourth message. In this way, the second network-side device may determine, based on the request of the terminal, to establish a direct data channel or an indirect data channel, thereby improving flexibility of establishing a data channel.

Optionally, in this embodiment of this application, the data processing method provided in this embodiment of this application further includes the following steps 601 to 605.

Step 601: The second network-side device sends a fifth message.

In this embodiment of this application, the fifth message is used to request establishment of a data channel.

Optionally, in this embodiment of this application, before step 103 (the first network-side device sends the first data to the terminal), the second network-side device may send the fifth message.

Optionally, in this embodiment of this application, the fifth message is a SIP message.

Step 602: The terminal receives the fifth message.

Step 603: The terminal sends a sixth message.

In this embodiment of this application, after receiving the establishment request, the terminal may send the sixth message to the second network-side device to request establishment of the indirect data channel; the second network-side device may receive the sixth message; and the terminal may establish the indirect data channel with the first network-side device. In this way, the second network-side device may determine, based on the request of the terminal, to establish a direct data channel or an indirect data channel, thereby improving flexibility of establishing a data channel.

Optionally, in this embodiment of this application, the fifth message carries third information, and the third information is used to request or indicate establishment of a direct data channel or establishment of a data channel in which a network-side device does not participate.
