[0002] This application claims priority to Chinese patent application No. 2024119974432, filed on December 31, 2024, entitled "Method, Apparatus and Electronic Equipment for Adjusting Business Rate", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communications, and more specifically, to a method, apparatus, and electronic device for adjusting service rates. Background Technology

[0004] To meet the demands of XR services for low latency, high reliability, low power consumption, and multi-service transmission, the 5G / 5G-Advanced standards have researched XR wireless network enhancement technologies. Specifically, 3GPP (3rd Generation Partnership Project) defined the basic framework for 5G networks to support XR services in Release 15, and studied the client architecture and key indicators for VR streaming services. Subsequently, starting with Release 16, 3GPP focused on XR technology research, specifically studying XR service application scenarios and defining Quality of Experience (QoE) parameters related to VR experiences. Furthermore, to improve user experience, 3GPP Release 17 defined application scenarios in SA1, defined key Quality of Service (QoS) indicators in SA2, and studied the impact of edge computing on XR services in SA6. Moreover, building upon existing time-sensitive technologies for wireless networks, technologies such as scheduling enhancement and resource allocation enhancement were studied, promoting the development of XR services in wireless networks and driving the widespread adoption of XR applications. As the first release of the 5G-Advanced phase, 3GPP R18 studied technologies such as XR service feature awareness, energy reduction, and capacity enhancement, aiming to further improve the capabilities of wireless networks to better support XR services.

[0005] For XR services, concepts such as multimodal communication and PDU (Protocol Data Unit) sets are introduced. In AR / VR applications, multimodal communication services combine ultra-low latency with high availability / reliability. Multimodal services are important in AR / VR applications, including IoT, robotics / television, disaster relief services, healthcare, gaming, and education. Typical multimodal communication can have different modalities that affect the user experience, including audio / video data, sensor data, haptic data, and feedback. Therefore, applications involving such use cases will generate data with drastically different requirements. When traffic with different QoS requirements exists in the RAN, the traffic is mapped to different DRBs (Data Radio Bearers). However, the RAN (RAN-based Notification Area) should be aware of the dependencies between traffic components. These dependencies can be static or dynamic. For example, haptic data can be associated with audio / video. Therefore, traditional rate control cannot adapt to the rate adjustment requirements of XR services.

[0006] There is currently no effective solution to the above problems. Summary of the Invention

[0104] First, some nouns or terms that appear in the explanation of the embodiments of this application shall be interpreted as follows:

[0105] New Radio (NR): This refers to the wireless interface of 5G mobile communication systems. It replaces the traditional 4G LTE technology, providing a more powerful, flexible, and efficient platform for mobile communication.

[0106] Radio Resource Control (RRC) is a key control plane protocol in mobile communication networks, also known as Radio Resource Management (RRM) or Radio Resource Allocation (RRA). It refers to the management, control, and scheduling of radio resources through specific strategies and methods. Its main objective is to make the most of limited wireless network resources while meeting quality of service requirements, ensuring coverage of the planned area, and maximizing service capacity and resource utilization.

[0107] Packet Data Convergence Protocol (PDCP) is a radio transport protocol stack in UMTS (Universal Mobile Telecommunications System), located at Layer 2 of the radio interface protocol stack. In 5G NR, PDCP sits above the RLC (Radio Link Control) layer and below the SDAP (Serving Data Adaptation Protocol) layer (user plane) or the RRC (Radio Resource Control) layer (control plane). It ensures efficient, secure, and reliable data transmission over the radio link by providing functions such as data compression, encryption, integrity protection, transmission, and reordering.

[0108] Protocol Data Unit (PDU): In a computer network, a PDU is a data unit used for information transmission between different layers of protocols. It is the basic data unit in network communication, representing the smallest unit of information transmitted between different network layers. A PDU contains both control and data information, used to enable information transmission and cooperation within the network.

[0109] Access and Mobility Management Function (AMF): This is one of the core network elements in a 5G network, primarily responsible for access control and mobility management of user equipment.

[0110] Discontinuous Reception (DRX): This refers to a terminal (such as a mobile phone, IoT device, etc.) turning on its receiver to enter an active state for a necessary period of time to receive downlink data, and then turning off the receiver to enter a sleep state for the remaining time, ceasing to receive downlink data. This operating mode is based on the fact that packet data streams are usually bursty, meaning there is data transmission for a period of time, followed by a longer period of no data transmission. When there is no data transmission, the terminal can reduce power consumption and thus improve battery life by stopping receiving relevant channels (such as PDCCH).

[0111] Physical Downlink Control Channel (PDCCH): This is an important physical channel in LTE and 5G NR (New Radio) wireless communication standards, mainly used to transmit downlink control information.

[0112] RAN-based Notification Area (RNA) is an important concept in 5G networks used to manage user equipment (UE) mobility and location information. It defines the area within which a UE can move freely without needing to notify the network of its specific location.

[0113] Non-Access-Stratum (NAS): It exists in the wireless communication protocol stack, especially in systems such as UMTS (Universal Mobile Telecommunications System), LTE (Long Term Evolution), and 5G NR (New Radio). In the protocol stack, the NAS is located at the highest layer of the control plane and is responsible for handling signaling and data transmission unrelated to the Radio Access Network (RAN).

[0114] Data Radio Bearer (DRB): A radio bearer specifically configured for a particular application or user traffic, allowing user equipment (UE) to transmit data between itself and the network. This data can be various forms of application data, such as web browsing, video streaming, and VoLTE calls.

[0115] To assist the RAN (Radio Access Network) in sensing XR services and optimizing resource allocation, the core network needs to provide the RAN with the following three types of information:

[0116] 1) Semi-static information at the QoS Flow level

[0117] The core network primarily provides QoS Flow-level semi-static information to the RAN through two methods: TSCAI and SMF (Session Management Function). Specific parameters are shown below:

[0118] The information provided by TSCAI includes: at least one of the UL and DL service cycles corresponding to the QoS Flow; and N6 jitter information related to the DL service cycle.

[0119] The information provided by SMF includes PDU Set QoS parameters for each QoS Flow: PSER: A QoS parameter related to the PDU Set, used to define the packet loss rate of the PDU Set between the RAN and UE. Note that the PSER is the same for all PDU Sets mapped to the same QoS Flow. For a QoS Flow, if a PSER exists, it replaces PER; PSDB: A QoS parameter related to the PDU Set, used to define the upper limit of latency between the N6 termination point of the PDU Set on the UE and UPF. Note that the PSDB is the same for all PDU Sets mapped to the same QoS Flow. For a QoS Flow, if a PSDB exists, it replaces PDB; PSIHI: A QoS parameter related to the PDU Set, used to indicate whether the application layer needs all PDUs within a PDU Set to obtain information units for that PDU Set.

[0120] 2) Dynamic information at the PDU Set level

[0121] For DL, UPF can identify PDU Sets and carry PDU Set-level dynamic information through the GTP-U header, and send it to the RAN. The specific information carried in the GTP-U header may include: the PDU Set's serial number (SN); the size of the PDU Set (in bytes); the serial numbers of the PDUs within the PDU Set; the indication information of the last PDU in the PDU Set; and PSI: QoS parameters related to the PDU Set, used to identify the relative importance between different PDU Sets.

[0122] 3) Data burst related information

[0123] Specifically, this includes: the header of the last PDU in the data burst carries an EoDB indication (optional).

[0124] In addition, for UL services, the terminal needs to dynamically identify parameters such as PDU Set, Data Busts and PSI, and send the relevant parameters to the network for resource scheduling optimization.

[0125] Regarding adaptive technologies for service rates, both 4G and 5G have proposed rate adaptive adjustment functions for voice IMS services. Since VoNR (Voice over NR) uses EVS coding, the CMR field position is not fixed under this coding method, making it impossible for base stations to achieve adaptive coding rates through CMR alone. Therefore, to achieve adaptive coding rates in 5G networks, the newly introduced Recommended birate technology is needed. The base station sends the recommended physical layer rate to the terminal through MAC layer control information, and the terminal judges and decides whether to reduce or increase the voice coding rate. Specifically, this process can be triggered by the gNodeB detecting changes in the UE's air interface rate, or by the UE detecting changes in uplink air interface capabilities and actively querying the gNodeB for the recommended rate.

[0126] MAC CE is an abbreviation for MAC Control Element. MAC CE is a means of exchanging control information between the UE and the network, besides RRC and NAS messages. It exchanges control information about the MAC layer. MAC CE is a method used in 5G systems for exchanging MAC layer control information between the UE and the network, including uplink and downlink parts. A MAC CE consists of a MAC header, MAC SDU, MAC CE, and padding. The subheader in the MAC header corresponds to the MAC PDU, CE, or padding. Downlink MAC CE involves DCQR Command, DRX Command, etc., as shown in Figure 1. The information included in the rate adjustment MAC CE is: LCID (Logical Channel ID), direction (UL / DL), recommended bit rate, and rate multiplier. The LCID is mapped to a DRB, therefore MAC CE itself is based on DRB granularity.

[0127] For XR services, concepts such as multimodal and PDU aggregation are introduced. In AR / VR applications, multimodal communication services combine ultra-low latency with high availability / reliability. Multimodal services are important in AR / VR applications, including IoT, robotics / telepresence, disaster relief services, healthcare, gaming, and education. Typical multimodal communication can have different modalities that affect the user experience, including audio / video data, sensor data, haptic data, and feedback. Therefore, applications involving such use cases will generate data with drastically different requirements. When traffic with different QoS requirements exists in the RAN, the traffic is mapped to different DRBs. However, the RAN should be aware of the dependencies between traffic components. These dependencies can be static or dynamic. For example, haptic data can be associated with audio / video. Therefore, traditional rate control cannot adapt to the rate adjustment requirements of XR services, specifically presenting the following problems:

[0128] 1. Only supports voice services and cannot support more types of services: In terms of speed, it only supports up to 8000 bits, which cannot meet the requirements of XR to reach speeds of 20Mbps or more. In addition, the service level is limited to voice services and cannot be extended to haptic, video and other types of services.

[0129] 2. Only supports DRB granularity adjustment: In XR, many services are based on flow granularity, and many speed reduction adjustments are also based on the flow level;

[0130] 3. Inability to support multiple services running simultaneously: XR introduces the new feature of multimodality. There is a certain correlation between multiple PDU sets. The rate adjustment of two independent MAC CEs may cause the application layer to process them separately and reject the MAC CE's speed adjustment request.

[0131] 4. How does the network side determine the rate limit or congestion of different QoS flows? Previously, the network only judged the rate limit through the MAC layer. This judgment was limited to the DRB granularity and could not determine which flow was limited. Therefore, the rate adjustment could not be accurately determined.

[0132] Based on the above analysis of requirements and reasons, the current 3GPP Rel-18 protocols cannot meet the rate adaptation requirements for XR, and new standardization methods are needed to enhance functionality in order to meet the needs of network deployment and optimization.

[0133] To address the problems existing in related technologies, embodiments of this application provide a method for adjusting service rates. This method can support simultaneous adjustment of the rates of multiple services in XR, and can support both DRB and FLOW granularity.

[0134] Figure 2 is a flowchart of a service rate adjustment method according to an embodiment of this application, applied to a terminal. As shown in Figure 2, the method includes the following steps:

[0135] Step S202: Receive a first Media Access Control (MAC) CE from the network side, or send a second MAC CE to the network side. The first MAC CE includes one or more first information sets, which include at least one of the following: a first logical channel identifier (LCID), direction, first bit rate, bit rate multiple, and QoS flow identifier. The second MAC CE includes one or more second information sets, which include at least one of the following: a second LCID, direction, second bit rate, bit rate multiple, and QoS flow identifier.

[0136] In this application embodiment, a MAC CE format is provided, as shown in Figure 3, illustrating the structure and usage scenarios of the RecommendedBitRateXR MAC CE. It is primarily used to explain the information elements contained in the first MAC CE and the time sequence of its operations. RecommendedBitRateXR supports QoS FLOW IDs and the coexistence of multiple service groups. From the content and structure of Figure 3, it appears to involve recommending data transmission rates for specific logical channels (LCIDs) and QoS flows. The following is a detailed explanation of the figure:

[0137] Time series: Figure 3 shows the different events that occurred at different time points (labeled Oct 1 to Oct 6), which helps to understand the usage process and timing of the first MAC CE.

[0138] LCID (Logical Channel Identifier): The logical channel identifier is used to uniquely identify the logical channel in data transmission. Different logical channels may carry different service flows, such as audio, video or haptic data.

[0139] UL / DL (Uplink / Downlink): Uplink indicates data transmission from UE (User Equipment) to the network, while downlink indicates data transmission from the network to the UE.

[0140] Bit Rate: Bit rate represents the data transmission rate and is an important indicator for measuring data transmission efficiency.

[0141] QoS FLOW: A QoS Flow is a data link in a 5G network used to carry specific service flows. Each QoS Flow has QoS parameters that match its service type.

[0142] MAC CE: MAC CE is the MAC layer control unit, used for exchanging control information between the network and the UE. In Figure 3, MAC CE is used by the network to send bit rate suggestions to the UE or by the UE to send bit rate queries to the network.

[0143] In the above method, the method further includes: after the terminal receives the first MAC CE, it initiates rate adaptation or rate negotiation with the peer entity.

[0166] In the above methods, the recommended bit rate is a uniform recommended bit rate supported for all services or a recommended bit rate supported for QoS Flow.

[0167] In the above method, supporting the recommended bit rate based on flow means that the terminal supports the recommended bit rate based on flow, and supporting the recommended bit rate based on flow can be set in both directions of transmission or reception, or individually in either direction.

[0170] In the above method, the first bit rate indicates the index value in the first rate table or the second rate table. The length of the first rate table is not less than 6 bits, and the recommended bit rate mapped or associated with the index value represents the recommended bit rate.

[0171] In the above method, the first rate table contains at least 16 index values, each index value corresponding to a recommended bit rate value.

[0172] In this embodiment of the application, the specific contents of the first rate table are as follows:

[0179] In the above method, multiple first information sets or second information sets enable indications indicate that the first MAC CE or the second MAC CE carries at least one first information set or second information set.

[0180] In the above method, the absence of multiple first information sets or second information set enable instructions indicates that the first MAC CE or the second MAC CE carries only one first information set or second information set.

[0181] In the above method, the fixed MAC CE size indicator represents the numerical size of the MAC CE format, in bits or bytes.

[0182] In the above method, the second RRC message is the RRCReconfiguration message in the 5G system or the RRC Reconfiguration message in the 6G system.

[0183] In the above method, the uplink logical channel configuration parameters include at least one of priority, priority bit rate, subcarrier spacing list, and first prohibition timer. The priority is the priority of the logical channel, and the first prohibition timer is configured to prohibit the terminal from retransmitting the exact same second MAC CE to the network side within the configured time in the uplink direction.

[0184] In the above method, the first granularity configuration is used to instruct the MAC CE to use either a radio data bearer (DRB) or a QoS flow. When the second RRC message does not contain the first granularity configuration, the first MAC CE or the second MAC CE adjusts the granularity to DRB or logical channel or does not contain QoS flow information.

[0190] In the above method, the upper layer includes at least one of the terminal's application layer, NAS layer, RRC layer, and terminal-side service application layer.

[0191] The method further includes: the terminal's Media Access Control (MAC) entity requesting the network to indicate at least one of a specific logical channel and QoS Flow, along with a recommended bit rate for a corresponding specific direction; if the terminal's upper-layer requesting device's MAC entity queries the network for the logical channel, at least one of the QoS Flow identifiers, and the recommended bit rate for the corresponding direction; if the query for the logical channel or QoS Flow identifier and the recommended bit rate for the corresponding direction is not triggered, the terminal's upper-layer requesting device's MAC entity triggers a query for the logical channel or QoS Flow and the recommended bit rate for the corresponding direction, wherein the direction includes uplink or downlink. A UL / DL field set to 0 indicates downlink. A UL / DL field set to 1 indicates uplink.

[0192] The service rate adjustment method provided in this application addresses the limitations of traditional solutions that only support voice service rate adjustment, extending to scenarios with composite services such as XR, and meeting the concurrent requirements of voice, video, and haptic services in XR. Furthermore, this method supports determining the rate adjustment granularity based on network configuration, choosing between DRB and QoS FLOW granularity, thus meeting the needs of multimodal XR scenarios. It also supports network congestion detection for both DRB and QoS FLOW, preventing asynchronous adjustments by a single method from causing rate adjustment rejection at the peer. Moreover, this method does not affect the terminal because the network-side solution has good forward compatibility and is easy to deploy and implement.

[0193] This application also provides another method for adjusting service rates, applied to a base station, including: sending a first Media Access Control (MAC) CE to a terminal, or receiving a second MAC CE sent by the terminal, wherein the first MAC CE includes one or more first information sets, the first information set including at least one of: a first logical channel identifier (LCID), direction, first bit rate, bit rate multiple, and quality of service (QoS) flow identifier; the second MAC CE includes one or more second information sets, the second information set including at least one of: a second LCID, direction, second bit rate, bit rate multiple, and QoS flow identifier.
