[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 21, 2023, with application number 202311231219.8 and invention name “Service Quality of Service QoS Policy Adjustment Method, Device, Terminal and Communication Equipment”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a method, apparatus, terminal and communication equipment for adjusting the quality of service (QoS) strategy of a service. Background Art

[0004] With the advancement of electronic technology, high-quality extended reality (XR) applications are becoming increasingly accessible and continue to develop rapidly. Consequently, there is a growing demand for enhancing the capabilities of the fifth-generation mobile communication technology system (5GS) to better support XR applications.

[0005] Currently, XR applications combined with cloud gaming (CG) services rely heavily on human-device interaction. This means that users provide instructions, such as waving a handle or making certain gestures. The XR device should generate and feedback new images based on the user's instructions to be displayed on the display device of the XR device. Delays are inevitable in this process. XR devices usually reduce end-to-end delays by adjusting uplink and downlink Quality of Service (QoS) parameters.

[0006] However, within the 5GS QoS framework, uplink and downlink QoS parameters are configured independently. For example, uplink QoS configuration only considers uplink latency, while downlink QoS configuration only considers downlink latency. XR devices reduce end-to-end latency by adjusting uplink or downlink QoS parameters independently. While network-side devices can monitor and adjust the QoS parameters of XR devices, this is inefficient and may compromise the overall Quality of Experience (QoE).

[0007] In summary, how to reduce the round-trip delay from XR devices to network-side devices is a technical problem that needs to be urgently solved in this field.

The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0038] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0039] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0040] 1) Virtual Reality (VR) is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment, immersing users in it and isolating them from reality.

[0041] 2) Augmented Reality (AR) is a technology that calculates the position and angle of a camera image in real time and adds corresponding images, videos, and 3D (3D) models. Users can simultaneously see the visual effect of virtual objects existing in the real environment, thus achieving an "enhancement" of the real scene.

[0042] 3) Extended Reality (XR) refers to the use of computers to combine the real and virtual to create a virtual environment where humans and computers can interact. XR is a general term for multiple technologies such as AR and VR. Through wearable devices and computer technology, XR can bring the audience an environment that combines the real and virtual and allows humans to interact with the computer.

[0043] With the advancement of electronic technology, high-quality extended reality (XR) applications are becoming increasingly accessible and continue to develop rapidly. Consequently, there is a growing demand for enhancing the capabilities of the fifth-generation mobile communication technology system (5GS) to better support XR applications.

[0044] Currently, XR applications combined with CG services rely heavily on human-device interaction. This means users provide commands, such as waving a controller or making gestures, and the XR device generates and responds with new images based on the user's instructions, which are then displayed on the XR device's display. Due to the nature of this interaction, it is more reasonable for network-side devices to guarantee round-trip latency from the XR device to the terminal, rather than simply guaranteeing latency in one direction (uplink or downlink).

[0045] For most XR applications combined with CG services, the complete XR device-to-terminal round-trip latency T e2e It can be expressed by the following formula: e2e =MTP-T processing -T rende r≤20ms-T processing -T render

[0046] MTP (motion-to-photon) represents the delay from motion to image. This delay is determined by the physiological characteristics of the human brain and is generally capped at 20ms. If this delay is exceeded, the user loses the immersive experience. Therefore, a 20ms delay is typically a hard limit for XR applications combined with CG services.

[0047] T processing Indicates the time required for the cloud or network-side device to process the user's input command and calculate the image data corresponding to the command based on the input command;

[0048] T render It refers to the delay caused by the user's XR head-mounted display (HMD) rendering the image data received from the network and displaying it on the device screen.

[0049] Since XR devices usually cover various forms and sizes, such as glasses and head-mounted displays. Different devices have different capabilities, such as processing power, battery capacity, and heat dissipation capacity. Therefore, the network-side device must adjust the QoS configuration not only according to the wireless capabilities of the device, but also according to the real-time hardware processing status of the device. For example, when the temperature of the XR device is too high, the performance of the GPU will be reduced due to the temperature control strategy, so T render If the network side equipment can perceive this information and adjust the uplink or downlink QoS strategy to compensate for the extended T render , that would be very helpful.

[0050] Therefore, in an embodiment of the present application, a first communication device receives device status information from a terminal, where the device status information is used to characterize the device status of the terminal when executing a first service. The first communication device determines a QoS policy for the first service based on the device status information and a first rule. The QoS policy for the first service includes an uplink QoS policy for the first service and a downlink QoS policy for the first service. The QoS policy is used to adjust transmission parameters of service data of the first service. The first communication device adjusts QoS parameters for the first service based on the QoS policy. The QoS parameters include transmission delays for uplink service data and downlink service data of the first service. The first rule requires that the sum of the transmission delays for uplink service data and downlink service data meet a preset condition. In this way, the first communication device can determine the QoS policy for the first service based on the device status information of the terminal, thereby enabling the first communication device to simultaneously adjust the transmission delays for uplink service data and downlink service data of the first service to reduce the round-trip delay between the terminal and the first communication device, thereby ensuring an immersive user experience.

[0058] The present invention provides a method for adjusting a QoS policy for a service. FIG2 shows a flowchart of the method provided by the present invention. The method is performed by a first communication device as an example. As shown in FIG2, the method for adjusting a QoS policy for a service provided by the present invention may include the following steps 201 to 203.

[0059] Step 201: A first communication device receives device status information of a terminal.

[0060] In an embodiment of the present application, the above-mentioned first communication device is a PCF network element in the core communication network.

[0061] In one embodiment of the present application, the terminal is a head-mounted electronic device, such as an MR device, a VR device, or an AR device.

[0062] In the embodiment of the present application, the above-mentioned device status information is used to represent the device status of the terminal when executing the first service.

[0063] In an embodiment of the present application, the above-mentioned device status information includes at least one of the following: temperature information of the terminal; remaining power information of the terminal; processor load information of the terminal; and other sensor information of the terminal.

[0064] Optionally, in the embodiment of the present application, in combination with FIG2 , as shown in FIG3 , the above step 201 specifically includes step 201a:

[0065] Step 201a: The first communication device receives device status information sent by the terminal via the second communication device and the third communication device.

[0066] In an embodiment of the present application, the above-mentioned second communication device can be an AMF network element in the communication core network.

[0067] In an embodiment of the present application, the above-mentioned third communication device can be an SMF network element in the communication core network.

[0068] Exemplarily, the above device status information is sent from the terminal to the second communication device, then from the second communication device to the third communication device, and finally from the third communication device to the first communication device, so that the first communication device can receive the device status information from the terminal.

[0069] Optionally, in the embodiment of the present application, in combination with FIG3 , as shown in FIG4 , the above step 201a specifically includes step 201a1:

[0070] Step 201a1: The first communication device receives a first signaling sent by the third communication device.

[0071] In the embodiment of the present application, the above-mentioned first signaling, second signaling and third signaling are all signalings dedicated to transmitting device status information.

[0072] In the embodiment of the present application, the above-mentioned first signaling is sent by the third communication device when it receives the second signaling from the second communication device.

[0073] In the embodiment of the present application, the above-mentioned second signaling is sent by the second communication device when it receives the third signaling from the terminal.

[0074] In an embodiment of the present application, the above-mentioned first signaling, second signaling and third signaling may be RRC signaling.

[0077] Step 201A: The terminal sends device status information to the first communication device.

[0078] Exemplarily, the electronic device may obtain the device status information of the terminal in real time, or may obtain the device status information of the terminal when an abnormality occurs in the device status information.

[0079] Exemplarily, the terminal may send the acquired device status information to the base station, which then sends it to the first communication device. Alternatively, the terminal may send the acquired device status information directly to the first communication device through a NAS message.

[0080] Optionally, in the embodiment of the present application, the above step 201A specifically includes the following steps 201A1:

[0081] Step 201A1: When an abnormality occurs in the device status of the terminal when executing the first service, the terminal sends device status information to the first communication device.

[0082] In this way, when the terminal detects that the device status is abnormal, it can send the abnormality information to the first communication device in a timely manner, so that the first communication device can adjust the QoS parameters according to the abnormal status information in the first time.

[0083] Step 201B: The first communication device receives device status information from the terminal.

[0084] Optionally, in the embodiment of the present application, in combination with FIG5 , as shown in FIG6 , the above step 201A specifically includes step 201C:

[0085] Step 201C: The terminal sends device status information to the first communication device via the second communication device and the third communication device.

[0086] Exemplarily, after the terminal sends the device status information to the second communication device, the second communication device sends the device status information to the third communication device, and finally the third communication device sends the device status information to the first communication device, so that the first electronic device can determine the QoS policy of the first service based on the received device status information.

[0087] Optionally, in the embodiment of the present application, the above step 201C specifically includes step 201C1:

[0088] Step 201C1: The terminal sends a third signaling to the second communication device.

[0089] In an embodiment of the present application, the third signaling is used by the second communication device to send the second signaling to the third communication device.

[0090] In an embodiment of the present application, the second signaling is used by the third communication device to send the first signaling to the first communication device.

[0091] In this way, the device status information can be transmitted between the terminal and the first communication device through the newly introduced signaling message.

[0092] Step 202: The first communication device determines a QoS policy for the first service based on the device state information and the first rule.

[0093] In the embodiment of the present application, the first service mentioned above is the service currently being run by the terminal.

[0094] For example, the first service may be a shooting game service, or a sports game service, etc.

[0095] In the embodiment of the present application, the QoS policy of the first service includes an uplink QoS policy of the first service and a downlink QoS policy of the first service.

[0096] In the embodiment of the present application, the above-mentioned QoS policy is used to adjust the transmission parameters of the service data of the first service.

[0097] In the embodiment of the present application, the uplink QoS policy is used to adjust the transmission parameters of the uplink service data of the first service.

[0098] In the embodiment of the present application, the downlink QoS policy is used to adjust the transmission parameters of the downlink service data of the first service.

[0099] Exemplarily, the above transmission parameters may include at least one of the following: transmission delay or transmission rate.

[0100] In the embodiment of the present application, the first rule is that the sum of the transmission delays of the uplink service data and the downlink service data meets a preset condition.

[0101] For example, the above preset condition can be expressed as the following formula 1:

[0102] Uplink service data transmission delay + downlink service data transmission delay + T processing +T render <20ms

[0103] Exemplarily, the first communication device determines an uplink QoS policy and a downlink QoS policy based on the received device state information, so that the transmission delay of the uplink service data of the first service adjusted by the uplink QoS policy, the transmission delay of the downlink service data of the first service adjusted by the downlink QoS policy, T processing and T render The sum is less than 20ms.

[0104] Step 203: The first communication device adjusts the QoS parameters of the first service based on the QoS policy.

[0105] In an embodiment of the present application, the above-mentioned QoS parameters include the transmission delay of the uplink service data and the downlink service data of the first service.

[0106] Exemplarily, the first communication device determines, according to the QoS policy, QoS parameters corresponding to the QoS policy, and then adjusts various transmission parameters in the first service according to the QoS parameters.

[0107] In this way, when the terminal is a head-mounted electronic device, the network side device, such as the first communication device mentioned above, can determine the QoS parameters corresponding to the QoS policy according to the QoS policy when the first service load is relatively heavy, and then adjust the various transmission parameters in the first service according to the QoS parameters, thereby ensuring that the end-to-end delay remains unchanged, actively adjust the uplink QoS parameters, and compensate by reducing the downlink QoS parameters.

[0108] It should be noted that the downlink QoS parameters of network-side devices may be achieved by reducing the amount of downlink data sent, which will lead to a decrease in the image quality of the head-mounted electronic device. In order to solve this problem, the head-mounted electronic device can actively enable interpolation, adjust the parameters related to the foveation rendering, and other means to compensate for the image quality.

[0109] In a method for adjusting a QoS policy for a service provided in an embodiment of the present application, a first communication device receives device status information from a terminal, the device status information being used to characterize the device status of the terminal when executing a first service. The first communication device determines a QoS policy for the first service based on the device status information and a first rule, the QoS policy for the first service including an uplink QoS policy for the first service and a downlink QoS policy for the first service, the QoS policy being used to adjust transmission parameters of service data of the first service. The first communication device adjusts QoS parameters for the first service based on the QoS policy, the QoS parameters including transmission delays for uplink and downlink service data of the first service. The first rule is that the sum of the transmission delays for uplink and downlink service data satisfies a preset condition. In this manner, the first communication device can determine the QoS policy for the first service based on the device status information of the terminal, thereby enabling the first communication device to simultaneously adjust the transmission delays for uplink and downlink service data of the first service, thereby reducing the round-trip delay between the terminal and the first communication device, thereby ensuring an immersive user experience.

[0110] Optionally, in the embodiment of the present application, in combination with FIG2 , as shown in FIG7 , the above step 203 specifically includes step 203a or step 203b:

[0111] Step 203a: When an abnormality occurs in the device state of the terminal when executing the first service, the first communication device adjusts the QoS parameters of the first service based on the QoS policy.

[0112] Optionally, in the embodiment of the present application, the abnormal device status includes at least one of the following:

[0113] The temperature of the terminal is greater than or equal to a first threshold;

[0114] The remaining battery power of the terminal is less than or equal to a second threshold;

[0115] The processor load of the terminal is greater than or equal to a third threshold.

[0116] Exemplarily, the first threshold, the second threshold, and the third threshold may be preset by the electronic device or may be user-defined.

[0117] Example 1: Taking the first threshold of 60°C as an example, when the terminal executes the first service, if the temperature of the terminal reaches 65°C, it is considered that the device status of the terminal at this time is abnormal. The first communication device determines the QoS policy based on the device status information where the abnormality occurs, and adjusts the QoS parameters of the first service according to the QoS parameters corresponding to the QoS policy.

[0118] Example 2: Taking the second threshold of 20% as an example, when the terminal executes the first service, if the remaining power of the terminal is 18%, it is considered that the device status of the terminal at this time is abnormal. The first communication device determines the QoS policy based on the device status information where the abnormality occurs, and adjusts the QoS parameters of the first service according to the QoS parameters corresponding to the QoS policy.

[0119] Example 3: Taking the third threshold of 80% as an example, when the terminal executes the first service, if the processor load of the terminal is 80%, it is considered that the device status of the terminal at this time is abnormal. The first communication device determines the QoS policy based on the device status information where the abnormality occurs, and adjusts the QoS parameters of the first service according to the QoS parameters corresponding to the QoS policy.

[0120] Exemplarily, after the terminal detects that the device status is abnormal when executing the first service, it sends the abnormal device status information to the first communication device. The first communication device determines the QoS policy based on the abnormal device status information, and adjusts the QoS parameters of the first service according to the QoS parameters corresponding to the QoS policy.

[0121] Step 203b: The first communication device periodically or aperiodically adjusts the QoS parameters of the first service based on the QoS policy.

[0122] Exemplarily, the above “periodicity” may be that the first communication device adjusts the QoS parameters of the first service based on the QoS policy after every preset time period.

[0123] Exemplarily, the above-mentioned preset duration may be preset by the first communication device, or may be customized by the user.

[0124] For example, the aforementioned "non-periodic" behavior may involve the first communications device proactively adjusting the QoS parameters of the first service based on a QoS policy when detecting that the first communications device is under heavy load. In other words, upon detecting that the QoS parameters of the first service need to be adjusted, the first communications device may proactively obtain device status information, determine a QoS policy, and adjust the QoS parameters of the first service based on the QoS policy.

[0125] Exemplarily, the terminal continuously sends device status information to the first communication device in real time, the first communication device actively periodically or aperiodically obtains the device status information sent by the terminal, and determines a QoS policy based on the device status information to adjust the QoS parameters of the first service.

[0126] In this way, the first communication device can proactively adjust the QoS parameters of the first service without having to wait until an abnormality occurs before making adjustments, thereby ensuring that users do not experience obvious delay issues.

[0127] The following takes the terminal as an XR device, the first communication device as a PCF network element in the core network, the second communication device as an AMF network element in the core network, and the third communication device as an SMF network element in the core network as an example. The detailed process of the QoS policy adjustment method for the service provided in the embodiment of the present application is described. Specifically, as shown in Figure 8, the following steps A0 to A6 are included:

[0128] Step A0: Assume that the XR device is executing the first service and has entered the connected state, and the user plane connection has been activated, such as a protocol data unit (PDU) session has been established between the XR device and the core network.

[0129] Step A1: The XR device reporting mechanism is triggered to obtain the device status information of the XR device.

[0130] Exemplarily, the above-mentioned reporting mechanism is that the device status data in the XR device reaches a preset threshold.

[0131] For example, the above-mentioned preset threshold value can be sent by the network-side device through a new broadcast message field, RRC signaling, or RRC message information element IE when the XR device registers. It is understood that the network-side device can be a core network or a base station. The network-side devices involved in the embodiments of this application all represent the core network.

[0132] Step A2: The XR device forwards the device status information obtained in step A1 to the AMF network element via the N1 interface through the third signaling.

[0133] Step A3: The AMF network element forwards the device status information in step A2 to the SMF network element via the N11 interface through the second signaling.

[0134] Step A4: The SMF network element forwards the device status information in step A3 to the PCF network element via the N7 interface through the first signaling.

[0135] Step A5: The PCF network element adjusts the QoS policy of the first service according to the device status information of the XR device. The QoS policy includes an uplink QoS policy and a downlink QoS policy.

[0136] Step A6: Based on the QoS policy, the PDU session is updated through the PDU session modification process to adjust the QoS parameters of the first service.

[0137] In this way, the embodiment of the present application realizes flexible adjustment of uplink QoS policy and downlink QoS policy, ensuring end-to-end delay of sensitive and interactive services, such as the application of XR devices in CG services.
