Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] To reduce the energy consumption of network equipment (such as base stations), shutdown techniques are often used, such as Cell Discontinuous Transmission (Cell DTX). In this technique, network equipment only transmits downlink data to terminals during specified time periods, and does not transmit downlink data during other time periods. This achieves energy saving by discontinuously scheduling data for network equipment.

[0003] However, how to further improve the energy efficiency of network devices by increasing the use of shutdown technology has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a communication method and related apparatus, which provides Cell DTX information and / or Cell DRX information parameters associated with QoS flow to a terminal through a network device. When the terminal's service matches the QoS flow, a shutdown technique can be used. By improving the use of the shutdown technique, the power consumption of the network device can be further reduced.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, a communication method is provided, the method comprising: receiving first information, the first information including at least one of cell discontinuous transmission (Cell DTX) parameter information and cell discontinuous reception (Cell DRX) parameter information, wherein the Cell DTX parameter information and / or Cell DRX parameter information are associated with a first target Quality of Service (QoS) flow; if the first target QoS flow meets the QoS requirements of a target service, then transmitting data corresponding to the target service according to the first information. By associating the first target QoS flow with the Cell DTX parameter information and / or Cell DRX parameter information, when a terminal's service matches the first target QoS flow, a network device can perform data scheduling based on the Cell DTX parameter information and / or Cell DRX parameter information. By scheduling data of services matching the first target QoS flow, the network device can schedule more service data based on the Cell DTX parameter information and / or Cell DRX parameter information, thereby reducing the power consumption of the network device and the terminal.

[0007] In some implementations of the first aspect, the first target QoS flow is different from the default QoS flow and the priority of the first target QoS flow is higher than that of the default QoS flow; or the default QoS flow is set as the first target QoS flow. Network devices can schedule more data based on Cell DTX parameter information and / or Cell DRX parameter information, thereby reducing the power consumption of terminals and network devices and improving energy efficiency.

[0008] In some implementations of the first aspect, the method further includes: if the first target QoS flow does not meet the service quality requirements of the target service, sending second information to the network device, the second information indicating that the first target QoS flow does not meet the service quality requirements of the target service. For a terminal in a connected state, after the terminal receives the first information, if the terminal does not allow the use of Cell DTX parameter information and / or CellDRX parameter information associated with the first target QoS flow, i.e., the first target QoS cannot meet the service quality requirements of the terminal's target service, the terminal may send the second information to the network device so that the network device can make a decision based on the second information. For example, the network side may establish a new QoS flow to carry the target service or the network device may trigger the terminal's handover process to switch the terminal to a base station that supports the target service.

[0009] In some implementations of the first aspect, the first information is carried in system information, and the method further includes:

[0010] During a random access procedure or a Radio Resource Control (RRC) connection procedure, the terminal sends third information to the network device. This third information is used to request adjustments to the Cell DTX parameter information and / or the Cell DRX parameter information. After receiving the first information, if the terminal supports a first target QoS flow (i.e., the first target QoS flow can meet the service quality requirements of the terminal's target service), the terminal further sends the third information to the network device. For example, if the third information includes Cell DTX periodicity information, the terminal can request adjustments to the Cell DTX periodicity through the third information. Thus, after receiving the first information, the terminal sends the third information to the network device to adjust the Cell DTX parameter information and / or the Cell DRX parameter information, thereby achieving negotiation between the terminal and the network device regarding the Cell DTX parameter information and / or the Cell DRX parameter information.

[0011] In some implementations of the first aspect, the step of transmitting data corresponding to the target service according to the first information if the first target QoS flow meets the service quality requirements of the target service includes: if the tolerable scheduling delay of the target service is greater than or equal to a scheduling delay threshold, then transmitting data corresponding to the target service according to the first information, wherein the scheduling delay threshold is determined based on the period of the Cell DTX and / or the period of the Cell DRX. By setting the matching rule of the first target QoS flow associated with the Cell DTX parameter information and / or the Cell DRX parameter information to a relationship between the tolerable scheduling delay of the target service and the scheduling delay threshold, the network device can schedule more data while ensuring that the first target QoS flow meets the service quality requirements of the target service of the terminal, thereby reducing the power consumption of the terminal and network device and improving energy efficiency.

[0012] In some implementations of the first aspect, the first information is carried in system information, and the method further includes: if the serving cell cannot meet the service quality requirements of the target service, then cell reselection is performed according to the target service, so that the reselected cell can meet the service quality requirements of the target service.

[0013] In some implementations of the first aspect, the first information further includes frequency information, and the cell reselection based on the target service includes: performing cell reselection based on the frequency information and the target service, so that the reselected frequency can meet the quality of service requirements of the target service.

[0014] In some implementations of the first aspect, the system information includes indication information, which is used to indicate that the terminal accesses the serving cell.

[0015] In some implementations of the first aspect, the priority of the first target QoS flow is set to be higher than the priority of at least one proprietary QoS flow.

[0016] In a second aspect, a communication system is provided, the communication system including network equipment and terminals;

[0017] The network device sends first information to the terminal. The first information includes at least one of Cell DTX parameter information for discontinuous transmission of cells and Cell DRX parameter information for discontinuous reception of cells. The Cell DTX parameter information and / or Cell DRX parameter information are associated with a first target Quality of Service (QoS) flow.

[0018] The terminal receives first information sent by the network device; if the first target QoS flow meets the service quality requirements of the target service, the terminal transmits the data corresponding to the target service according to the first information.

[0019] Thirdly, a communication device is provided, comprising: a memory including computer-readable instructions; and a processor communicating with the memory, the processor being configured to execute the computer-readable instructions, causing the communication device to perform the communication method described in any one of the first aspects.

[0020] Fourthly, a computer-readable storage medium is provided, including a program or instructions that, when executed by a processor, implement the communication method as described in any one of the first aspects.

[0021] Fifthly, a chip is provided, including a processor for retrieving and executing instructions stored in a memory, causing a communication device on which the chip is mounted to perform the communication method described in any one of the first aspects.

[0022] A sixth aspect provides a computer program product, characterized in that the computer program product includes instructions that, when executed by a computer, implement the method as described in any one of the first aspects.

[0023] The beneficial effects of each possible implementation of the communication method provided in the second aspect, the communication device provided in the third aspect, the computer-readable storage medium provided in the fourth aspect, the chip provided in the fifth aspect, and the computer program product provided in the sixth aspect of the embodiments of this application can be referred to the descriptions of the various possible implementations in the first aspect, and will not be repeated here.

[0033] The technical solutions in this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments in this specification, and not all of them.

[0034] In communication systems, especially 5G communication systems, energy saving in terminals and network equipment (such as base stations) is of great importance. Currently, for network equipment, Cell DRX can be used to receive data and / or Cell DTX can be used to transmit data. By employing corresponding shutdown technologies, energy saving in network equipment can be achieved.

[0035] As shown in Figure 1 Figure 1 This is a schematic diagram of a Cell DRX cycle. (Example) Figure 1 As shown, cell 1 adopts a periodic CellDRX configuration, with the DRX period including an active period (Cell DRX on) and an inactive period (Cell DRX off). During the Cell DRX on period, network devices transmit downlink services with terminals; during the Cell DRX off period, network devices stop transmitting downlink services with terminals. The longer the Cell DRX off period, the longer and deeper the shutdown duration and shutdown depth of the network devices can achieve, resulting in better energy savings. How can the energy consumption of network devices be reduced by increasing the shutdown duration and shutdown depth?

[0036] Quality of Service (QoS) plays a crucial role in communication systems, especially in resource-constrained environments such as wireless networks, broadband networks, and data center networks. The goal of QoS is to ensure that network resources are effectively allocated to different applications and services, thereby meeting the diverse network performance requirements of various services. In 5G networks, QoS flows are a key concept for implementing QoS. Compared to EPS bearers in 4G / LTE networks, 5G QoS flows provide more granular QoS control. In 5G networks, QoS flows are collaboratively managed by the core network (such as 5GC) and the access network (such as gNB). The core network is responsible for formulating and issuing QoS policies, while the access network is responsible for executing specific scheduling policies and resource allocation to ensure that the data transmission of each QoS flow meets its predetermined QoS indicators. In other words, QoS flows are used to guarantee the quality of service for different services and applications. Based on their characteristics and application scenarios, QoS flows can be divided into two main categories: default QoS flows and dedicated QoS flows. The default QoS flow is a QoS flow automatically established when a UE (User Equipment) attaches to a 5G network. It serves as the default channel providing basic connectivity and data transmission services to the UE, typically used for services without specific QoS requirements, such as web browsing and email. Dedicated QoS flows are QoS flows specifically established for particular services or applications, aiming to provide customized QoS guarantees. Establishing these QoS flows usually requires additional signaling interaction between the network and the UE to negotiate and confirm specific QoS parameters.

[0037] To address the aforementioned issues, this application provides a communication method that associates Cell DTX parameter information and / or Cell DRX parameter information with a target QoS flow. Thus, when a user's service data matches the target QoS flow, the network-side device schedules the data corresponding to the target service based on the Cell DTX parameter information and / or Cell DRX parameter information. This allows the network device to schedule more service-related data based on the Cell DTX parameter information and / or Cell DRX parameter information, thereby improving the energy-saving performance of the network-side device.

[0038] The following section introduces some of the terms used in the embodiments of this application.

[0039] (1) Cell DTX

[0040] Cell DTX is a data transmission mechanism proposed for network devices to save power. Based on the Cell DTX mechanism, the DTX cycle of a cell provided by a network device includes an active period and an inactive period. During the active period of the cell's DTX cycle, the network device sends specific indication information (such as unicast scheduling information) or downlink data to terminals within the signal coverage area of ​​the cell. During the inactive period of the cell's DTX cycle, the network device does not send specific indication information (such as unicast scheduling information) or downlink data. In other words, through the Cell DTX mechanism, the network device can concentrate the data to be transmitted in the cell during the active period, while during the inactive period, network devices associated with the cell, such as base stations, enter a dormant state and do not send indication information or downlink data signals, thereby achieving the purpose of saving power consumption.

[0041] (2) Cell DRX

[0042] Cell DRX is a mechanism for network devices to receive data, designed to save power. Based on the Cell DRX mechanism, the DRX cycle of a specific cell provided by the network device includes an active period and an inactive period. During the active period of the DRX cycle of that cell, the network device receives uplink signals transmitted by terminals within the signal coverage area of ​​that cell. During the inactive period of the DRX cycle of that cell, the network device does not receive uplink signals. In other words, through this Cell DRX mechanism, the network device can concentrate on receiving uplink signals during the active period of the DRX cycle of that cell, while the cell enters a dormant state and does not receive uplink signals during the inactive period, thereby achieving the purpose of saving power.

[0043] Figure 2 This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 2 As shown, the communication system includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (e.g., Figure 2 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 2 RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 2(Not shown in the image). Terminal 120 is wirelessly connected to RAN node 110. Terminals and RAN nodes can be interconnected via wired or wireless means. Communication system 1000 may also include core network 200. RAN node 110 is connected to core network 200 via wireless or wired means. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN node. Communication system 1000 may also include Internet 300.

[0044] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, or a future radio access system as defined in the 3rd generation partnership project (3GPP), or it can be a WiFi system. RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0045] A RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access a communication system wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can also be a macro base station (such as...) Figure 2 110a in the text), can also be a micro base station or an indoor station (such as... Figure 2 110b in the middle can also be a relay node or a donor node.

[0046] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). The RU can be included in radio frequency equipment, such as in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0047] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and a RU can be called an open RU (O-RU).

[0048] In NR technology, a RAN node (e.g., a gNB) can consist of one gNB Centralized Unit (CU) and one or more gNB Distributed Units (DUs). gNB-CU and gNB-DU are different logical nodes and can be deployed on different physical devices or on the same physical device.

[0049] Considering a separate control plane and user plane architecture, the gNB-CU can be further divided into a Central Unit-Control Plane (CU-CP) entity (or CU-CP node) and a Central Unit-User Plane (CU-UP) entity (or CU-UP node). The gNB-CU-CP is the control plane entity, providing signaling control, while the gNB-CU-UP is the user plane entity, providing terminal data transmission. The gNB-CU-CP and gNB-CU-UP are connected via an E1 interface, the gNB-CU-CP and gNB-DU are connected via an F1-C interface, and the gNB-CU-UP and gNB-DU are connected via an F1-U interface. Its structure is as follows: Figure 3 As shown, Figure 3 This is a schematic diagram of the separate architecture of gNB-CU-CP and gNB-CU-UP.

[0050] For example Figure 3 The architecture shown also has the following characteristics:

[0051] A gNB will contain one gNB-CU-CP, multiple gNB-CU-UPs, and multiple gNB-DUs;

[0052] One DU can only connect to one gNB-CU-CP;

[0053] One CU-UP can only be connected to one gNB-CU-CP;

[0054] A DU can be connected to multiple gNB-CU-UPs under the control of the same CU-CP;

[0055] A CU-UP can be connected to multiple gNB-DUs under the control of the same CU-CP.

[0056] It should be understood that Figure 3 This is merely an example and should not impose any limitations on the architecture of the gNB. For example, in an architecture with separate CU-DU and CP-UP, the gNB may include only one gNB-CU-UP, one gNB-CU-CP, and one gNB-DU, or it may include more gNB-CU-UP and gNB-DU. This application does not impose any limitations.

[0057] In one possible scenario, for example, the RAN node can be the aforementioned CU, DU, CU-CP, or CU-UP. CU and DU can be configured separately or included in the same network element, such as in a BBU. RU can be included in radio frequency equipment or radio frequency units, such as in RRU, active antenna unit (AAU), or remote radio head (RRH).

[0058] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0059] For example, Figure 4 The diagram shown is a schematic of an example RAN node. For example... Figure 4 As shown, a RAN node includes one or more CUs, one or more DUs, and one or more radio units (RUs). For clarity, Figure 4 Only one CU, DU, and RU are shown. The CU is used to connect to the core network and one or more DUs. Optionally, the CU may have some of the core network's functions. The CU may include CU-CP and CU-UP.

[0060] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of the protocol layers below the PDCP layer (such as the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and / or the Physical (PHY) layer). Alternatively, the CU can be configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC and / or SDAP layers), and the DU can be configured to implement the functions of the protocol layers below the PDCP layer (such as the RLC, MAC, and / or PHY layers).

[0061] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0062] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal location updates, terminal registration with the network, and terminal handover.

[0063] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in the terminal.

[0064] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0065] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0066] The RAN node in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, the RAN node can be a server loaded with the corresponding software module. The embodiments of this application do not limit the specific technology or device form used in the RAN node. For ease of description, a base station is used as an example of a RAN node in the following description.

[0067] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal.

[0068] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0069] The roles of base stations and terminals can be relative, for example, Figure 2 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 2 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 2 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0070] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0071] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0072] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. In order to communicate with the base station, the terminal needs to establish a radio connection with a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with this serving cell, it is also subject to interference from signals from neighboring cells.

[0073] The transmission indication method provided in the embodiments of this application will be explained in detail below.

[0074] Figure 5 This is a flowchart illustrating a communication method provided in an embodiment of this application. This method can be applied to the communication system described above, and the network device in the following embodiments can be... Figure 2 RAN100 in this context can also be a core network device. See [link / reference] Figure 5 The method includes the following steps:

[0075] S501, the network device sends first information to the terminal, and the terminal receives the first information sent by the network device. The first information includes at least one of Cell DTX parameter information and Cell DRX parameter information, and the Cell DTX parameter information and / or Cell DRX parameter information are associated with the first target QoS flow.

[0076] Optionally, the Cell DTX parameter information includes Cell DTX-related configuration parameters, such as one or more of the following: the Cell DTX period, the start time slot of the Cell DTX active period or the offset relative to a reference point, and the duration of each Cell DTX active period (or inactive period). The Cell DRX parameter information includes Cell DRX-related configuration parameters, such as one or more of the following: the Cell DRX period, the start time slot of the Cell DRX active period or the offset relative to a reference point, and the duration of each Cell DRX active period (or inactive period).

[0077] Optionally, the Cell DTX parameter information includes first indication information, which indicates whether the current cell supports Cell DTX parameter information associated with QoS flows; if the current cell supports Cell DTX parameter information associated with QoS flows, the first information also includes Cell DTX parameter information.

[0078] Optionally, the Cell DRX parameter information also includes second indication information, which is used to indicate whether the current cell supports Cell DRX parameter information associated with QoS flows; if the current cell supports Cell DRX parameter information associated with QoS flows, then the first information also includes Cell DRX parameter information.

[0079] Optionally, Cell DTX parameter information and / or Cell DRX parameter information are associated with a first target QoS flow; if Cell DTX parameter information is associated with a first target QoS flow, then if the terminal's service data matches the first target QoS flow, the network device schedules the terminal's service data according to the Cell DTX parameter information; if Cell DRX parameter information is associated with a first target QoS flow, then if the terminal's service data matches the first target QoS flow, the network device schedules the terminal's service data according to the Cell DRX parameter information.

[0080] Optionally, the network device sends the first information to the terminal through system information. For example, the system information sent by the base station carries the first information, such as a System Information Block (SIB) 1. Of course, after the terminal accesses the network, the network device can also send dedicated signaling to the terminal, with the dedicated signaling carrying the first information; that is, the first information is transmitted through dedicated signaling. For example, the base station sends Radio Resource Control Reconfiguration (RRCReconfiguration) to the terminal, with RRCReconfiguration carrying the first information. Alternatively, the network device can also send Non-Access Stratum (NAS) information to the terminal, with the NAS information carrying the first information; that is, the first information is transmitted through NAS information. It is easy to understand that the network device can transmit the first information through any of the above three methods.

[0081] Optionally, if the first information includes multiple parameters, the network device can transmit the first information through at least two of the three methods described above. For example, if the first information includes first indication information and the Cell DTX period, the system broadcast sent by the network device carries the first indication information. If the current cell supports Cell DTX parameter information associated with QoS flows, then RRCReconfiguration carries the Cell DTX period; that is, the Cell DTX period is transmitted through RRC Reconfiguration. Thus, the network device sends the first information to the terminal through system broadcast and dedicated signaling.

[0082] Optionally, if the NAS information sent by the network device (e.g., SMF) to the terminal carries the first information, then before the network device sends the NAS information to the terminal, the access network device sends Cell DTX parameter information and / or Cell DRX parameter information to the network device. After receiving the Cell DTX parameter information and / or Cell DRX parameter information sent by the access network device, the network device then sends the Cell DTX parameter information and / or Cell DRX parameter information to the terminal.

[0083] S502. If the first target QoS flow meets the service quality requirements of the target service, the terminal transmits the data corresponding to the target service according to the first information.

[0084] Optionally, after receiving the first information, the terminal further determines whether it supports the first target QoS flow. For example, it determines whether the terminal supports the first target QoS flow based on its configuration or capabilities. For another example, the terminal determines whether the tolerable scheduling delay of the target service is greater than the period of Cell DTX or Cell DRX. If the tolerable scheduling delay of the target service is greater than or equal to the period of Cell DTX or Cell DRX, then the terminal supports the first target QoS flow; if the tolerable scheduling delay of the target service is less than the period of Cell DTX or Cell DRX, then the terminal does not support the first target QoS flow.

[0085] Optionally, since both Cell DTX and Cell DRX have active and inactive periods, data transmission between the terminal and network device is suspended during the inactive period, and can transmit data normally during the active period. Therefore, if the terminal supports a first target QoS stream associated with Cell DTX parameter information and / or Cell DRX parameter information, and the first target QoS stream meets the service quality requirements of the user's target service, then the data corresponding to the target service is transmitted through the first target QoS stream, and the network device schedules the data corresponding to the target service according to the Cell DTX parameter information and / or Cell DRX parameter information. If the first information includes Cell DTX parameter information, then during the active period of Cell DTX, the terminal sends the data of the target service through the first target QoS stream; during the inactive period of Cell DTX, the terminal suspends the transmission of the data of the target service. If the first information includes Cell DRX parameter information, then during the active period of Cell DRX, the terminal receives the data of the target service through the first target QoS stream; during the inactive period of Cell DRX, the reception of the data of the target service is suspended.

[0086] Thus, by associating the first target QoS flow with Cell DTX and / or Cell DRX parameter information, when a terminal's service matches the first target QoS flow, the network device can perform data scheduling based on the Cell DTX and / or Cell DRX parameter information. By scheduling data for services matching the first target QoS flow, the network device can schedule data for more services based on the Cell DTX and / or Cell DRX parameter information, reducing power consumption for both the network device and the terminal.

[0087] In some embodiments, a default QoS stream is set as the first target QoS stream. Thus, when the default QoS stream meets the QoS requirements of the target service, i.e., when the terminal's target service matches the default QoS stream, the target service data is transmitted through the default QoS stream. Since the default QoS stream is typically a non-GBR (not guaranteeing bit rate) QoS stream, it has lower resource requirements. The default QoS stream typically does not guarantee a specific bit rate or low latency, making it suitable for services with low QoS requirements. The network device schedules the data carrying the target service within the default QoS stream according to Cell DTX and / or Cell DRX parameter information. Because the default QoS stream can carry a large amount of service data, the network device can schedule more data based on the Cell DTX and / or Cell DRX parameter information, thereby reducing the power consumption of the terminal and network device and improving energy efficiency.

[0088] In some embodiments, when a Protocol Data Unit (PDU) session is created or modified, the network device configures corresponding QoS rules for the terminal according to service requirements and network policies. The QoS rules include matching rules for a first target QoS flow and matching rules for a default QoS flow. The matching rules for the first target QoS flow differ from those for the default QoS flow; that is, the first target QoS flow is different from the default QoS flow, and the first target QoS flow has a higher priority than the default QoS flow. Thus, during QoS flow matching, because the first target QoS flow has a higher priority than the default QoS flow, the data of the target service is preferentially matched with the first target QoS flow, so that more data of the target service can be carried through the first target QoS flow. The network device schedules the data of the target service carried by the first target QoS flow according to Cell DTX parameter information and / or Cell DRX parameter information to reduce the power consumption of the terminal and network device and improve energy efficiency. Furthermore, the default QoS flow is the lowest priority QoS flow; when the data corresponding to the terminal's service does not match a corresponding QoS flow, the data can be carried through the default QoS flow.

[0089] In some embodiments, since the first target QoS flow is associated with Cell DTX parameter information and / or Cell DRX parameter information, the priority of the first target QoS flow can be increased so that the first target QoS flow can be preferentially matched with the terminal's services. This allows the first target QoS flow to carry more service data, and the network device can then schedule more data according to the Cell DTX parameter information and / or Cell DRX parameter information, thereby reducing the power consumption of the terminal and network device and improving energy-saving performance.

[0090] In some embodiments, the priority of the first target QoS flow is set higher than the priority of at least one dedicated QoS flow. A dedicated QoS flow refers to a flow with specific QoS parameters (such as latency, jitter, bandwidth, etc.) established to meet the needs of a specific service or application. Since the priority of the dedicated QoS flow is higher than the priority of the default QoS flow, and the priority of the first target QoS flow is higher than the priority of at least one dedicated QoS flow, by increasing the priority of the first target QoS flow, it can be prioritized for matching with the terminal's services. This allows the network device to schedule more data based on Cell DTX parameter information and / or Cell DRX parameter information, thereby reducing the power consumption of the terminal and network device and improving energy efficiency.

[0091] In some embodiments, the first target QoS flow has a higher priority than other QoS flows, meaning the first target QoS flow has the highest priority. Thus, during QoS flow matching, the first target QoS flow has the highest priority and is preferentially matched with the terminal's services. This allows the first target QoS flow, associated with the first information, to carry more services. The network device schedules more data based on Cell DTX parameter information and / or Cell DRX parameter information, further reducing the power consumption of the terminal and network device and improving energy efficiency.

[0092] As is easily understood, when a Protocol Data Unit (PDU) session is created or modified, the network device configures corresponding QoS rules for the terminal based on service requirements and network policies. The QoS rules include the matching rules for the first target QoS flow. For data corresponding to the target service, if the data meets the matching rules of the first target QoS flow, or in other words, the data matches the matching rules of the first target QoS flow, then the first target QoS flow meets the service quality requirements of the target service, and the data can be transmitted through the first target QoS flow. If the data is uplink data corresponding to the target service, the terminal performs the matching of uplink data and QoS flow. If the data is downlink data corresponding to the target service, the network device (e.g., User Plane Function (UPF)) performs the matching of uplink data and QoS flow.

[0093] Optionally, the matching rules for the first target QoS flow include the packet filter set (PFS) in the packet filter set corresponding to the first target QoS flow. That is, if the data corresponding to the target service matches the PFS corresponding to the first target QoS flow, then the first target QoS flow meets the service quality requirements of the target service and can carry the data of the target service through the first target QoS flow.

[0094] Optionally, service scheduling latency is a primary quality of service requirement for the target service. Network devices scheduling service data based on Cell DTX and / or Cell DRX can increase the transmission latency of the data corresponding to the target service. Therefore, a scheduling latency threshold can be determined using CellDTX and / or CellDRX parameter information. The matching rule for the first target QoS flow is whether the tolerable scheduling latency of the target service is greater than or equal to the scheduling latency threshold. If the tolerable scheduling latency of the target service is greater than or equal to the scheduling latency threshold, then the first target QoS flow meets the quality of service requirements of the target service; if the tolerable scheduling latency of the target service is less than the scheduling latency threshold, then the first target QoS flow does not meet the quality of service requirements of the target service.

[0095] Optionally, the scheduling delay threshold corresponds to the packet filter of the first target QoS flow. That is, each packet filter has a corresponding scheduling delay threshold. If the data of the target service matches the packet filter, the tolerable scheduling delay of the target service is greater than or equal to the scheduling delay threshold of the first target QoS flow, meaning that the first target QoS flow meets the service quality requirements of the target service. If the data of the target service does not match the packet filter, the tolerable scheduling delay of the target service is less than the scheduling delay threshold of the first target QoS flow, meaning that the first target QoS flow does not meet the service quality requirements of the target service.

[0096] Optionally, the filtering rules in the packet filter corresponding to the first target QoS flow include a 5-tuple, which includes the source IP address, destination IP address, source port, destination port, and protocol type. The packet filter can formulate rules based on the specific values ​​or ranges of the 5-tuple to determine which data should be allowed to pass, which should be blocked, or which should be specially processed. Since the scheduling delay threshold corresponds to the packet filter of the first target QoS flow, the scheduling delay threshold also corresponds to the 5-tuple; that is, each 5-tuple has a corresponding scheduling delay threshold.

[0097] Optionally, if the first information includes Cell DTX parameter information, and the Cell DTX parameter information includes the period of Cell DTX, the scheduling delay threshold can be determined based on the period of Cell DTX.

[0098] Optionally, if the first information includes Cell DRX parameter information, and the Cell DRX parameter information includes the period of Cell DRX, the scheduling delay threshold can be determined based on the period of Cell DRX.

[0099] In some embodiments, the period of Cell DTX or Cell DRX can be set as the scheduling delay threshold. Of course, after obtaining the period of Cell DTX or Cell DRX, the efficiency of the scheduling algorithm used and the current network latency can be obtained; then, the corresponding scheduling delay threshold can be determined based on the period of Cell DTX or Cell DRX, the efficiency of the scheduling algorithm, and the current network latency.

[0100] In some embodiments, the scheduling delay threshold can be determined by the terminal. For example, if the Cell DRX parameter information includes the period of Cell DRX, the terminal determines the scheduling delay threshold based on the period of Cell DRX. If the Cell DTX parameter information includes the period of Cell DTX, the terminal determines the scheduling delay threshold based on the period of Cell DTX. The scheduling delay threshold can also be determined by the network device. For example, if the first information also includes a scheduling delay threshold, the network device determines the scheduling delay threshold based on the period of Cell DRX and / or the period of Cell DTX.

[0101] Figure 6 This is a flowchart of a communication method provided in an embodiment of this application. See also... Figure 6 The method includes the following steps:

[0102] S601, The network device sends the first information to the terminal;

[0103] The content and sending method of the first message can be found in S501, and will not be repeated here.

[0104] S602, The terminal sends a second message to the network device, the second message being used to indicate that the first target QoS flow does not meet the service quality requirements of the target service.

[0105] Optionally, for a terminal in a connected state, after the terminal receives the first information, if the terminal does not allow the use of the Cell DTX parameter information and / or Cell DRX parameter information associated with the first target QoS flow, that is, the first target QoS cannot meet the service quality requirements of the terminal's target service, the terminal may send the second information to the network device so that the network device can make a decision based on the second information. For example, the network side may establish a new QoS flow, carry the target service through the new QoS flow, or the network device may trigger the terminal's handover process to switch the terminal to a base station that supports the target service.

[0106] Optionally, the terminal determines network performance indicators, such as signal quality, latency, and packet loss rate, based on the service quality requirements of the target service; then it defines measurement events based on the network performance indicators; for example, if the latency is greater than the service's tolerable latency, a measurement event is triggered, and the measurement result (e.g., second information) is sent to the network device for decision-making by the network side.

[0107] In some embodiments, after a terminal in a connected state receives the first information, if the terminal does not allow the use of Cell DTX parameter information and / or Cell DRX parameter information associated with the first target QoS flow, and the terminal can obtain the QoS parameters of the second target QoS flow, the terminal sends the QoS parameters of the second target QoS flow to the network device to request the network device to establish the second target QoS flow based on the QoS parameters of the second target QoS flow, and the second target QoS flow can meet the service quality requirements of the terminal's target service. If the terminal cannot obtain the QoS parameters of the second target QoS flow, the terminal sends the second information to the network device.

[0108] Optionally, if the first target QoS flow is the default QoS flow and the priority of the first target QoS flow is greater than the priority of at least one dedicated QoS flow, that is, there is currently no default QoS flow as a "fallback" QoS flow, then if the terminal's target service does not find a matching target QoS flow, the terminal can send second information to the network device so that the network device can create a new QoS flow or trigger the terminal to switch.

[0109] Optionally, the second target QoS flow has associated Cell DTX parameter information and / or Cell DRX parameter information. Thus, after the second target QoS flow is established and meets the QoS requirements of the terminal's target service, the target service data can be transmitted through the second target QoS flow. The network device schedules the target service data according to the Cell DTX parameter information and / or Cell DRX parameter information associated with the second target QoS flow, thereby reducing the power consumption of both the network device and the terminal.

[0110] Optionally, the Cell DTX parameter information and / or Cell DRX parameter information associated with the second target QoS flow are different from the Cell DTX parameter information and / or Cell DRX parameter information associated with the first target QoS flow. For example, the Cell DTX period associated with the second target QoS flow is shorter than the Cell DTX period of the first target QoS flow.

[0111] Figure 7 This is a flowchart of a communication method provided in an embodiment of this application. See also... Figure 7 The method includes the following steps:

[0112] S701, The network device sends the first information to the terminal;

[0113] The content and sending method of the first message can be found in S501, and will not be repeated here.

[0114] S702, The terminal sends third information to the network device, the third information being used to request adjustment of Cell DTX parameter information and / or Cell DRX parameter information.

[0115] Optionally, after receiving the first information, if the terminal supports the first target QoS flow, meaning the first target QoS flow can meet the service quality requirements of the terminal's target service, the terminal further sends third information to the network device. For example, if the third information includes Cell DTX periodicity information, the terminal can request adjustment of the Cell DTX periodicity through the third information. Thus, after receiving the first information, the terminal sends the third information to the network device to adjust the Cell DTX and / or Cell DRX parameter information, thereby achieving negotiation between the terminal and the network device regarding the Cell DTX and / or Cell DRX parameter information.

[0116] Optionally, after receiving the third information sent by the terminal, the network device sends a fourth information to the terminal. The fourth information includes updated Cell DTX parameter information and / or updated Cell DRX parameter information. Thus, through the interaction between the network device and the terminal, the update of the Cell DTX parameter information and / or Cell DRX parameter information associated with the first target QoS flow is achieved.

[0117] Optionally, after receiving the third information sent by the terminal, if the network device determines the conditions for the terminal to trigger frequency switching based on the third information, such as the period of the Cell DTX requested by the third information being updated, and the current frequency point cannot meet the updated Cell DTX period, then the network device sends switching information to the terminal. The switching information is used to instruct the terminal to switch to the new frequency point.

[0118] In some embodiments, if the UE is in a disconnected state, which includes an idle state and an inactive state, since no stable connection has been established between the terminal and the network device, the terminal in the disconnected state receives the first information through system information. Of course, if the first information includes multiple parameter information, such as the first information including first indication information and the period of CellDTX, then the system information carries at least one parameter information. During or after random access for the user, the network device sends other parameter information to the terminal.

[0119] In some embodiments, the first information is carried on system information, and the method further includes: sending third information to the network device during a random access procedure or a Radio Resource Control (RRC) connection procedure, the third information being used to request adjustment of Cell DTX parameter information and / or Cell DRX parameter information. Thus, for a terminal in a non-connected state, after the terminal receives system information including the first information, if the terminal supports the first information, the terminal can send the third information to the network device during a random access procedure or an RRC connection procedure, and the terminal negotiates Cell DTX parameter information and / or Cell DRX parameter information with the network device through the third information.

[0120] Optionally, when a terminal in a disconnected state receives system information sent by a network device, and the system information also includes indication information, the indication information is used to instruct the terminal to access the serving cell. If the terminal supports a first target QoS flow, then the terminal can access the serving cell. For example, the indication information is used to indicate the resources and configuration of the Random Access Channel (RACH), such as the preamble packets and sequence, the size of the random access response window, etc. The terminal initiates a random access procedure to access the serving cell based on the indication information.

[0121] Optionally, if the terminal sends third information to the network device during the random process, the third information is carried in the random access request message (Msg1) or the random access completion message (Msg3). For example, the third information is carried through the Media Access Control Element (MAC CE) in Msg3.

[0122] Optionally, if the terminal sends third information to the network device during the RRC connection process, the RRC connection request carries the third information, wherein the terminal sends the RRC connection request and Msg3 to the network device together.

[0123] In some embodiments, if the terminal is in a disconnected state and the serving cell does not meet the service quality requirements of the target service, the terminal can perform cell reselection according to the target service so that the serving cell accessed after reselection can meet the service quality requirements of the terminal's target service.

[0124] Optionally, if the serving cell to be accessed cannot provide the terminal with services that meet the quality of service requirements of its business, the terminal will set the serving cell to be accessed to be blocked (for example, set the status of the cell to "bar") to prevent the user from selecting the serving cell again after cell reselection.

[0125] Optionally, the first information also includes frequency point information, so that the terminal can perform cell reselection based on the frequency point information and the target service. The frequency point information is either a frequency point recommended for the terminal to access or a frequency point prohibited for the terminal node. Of course, the frequency point can also be a new frequency point, that is, a frequency point different from the current serving cell, so that the terminal can perform inter-frequency reselection based on the frequency point information.

[0126] For example, in the broadcast information sent by the network device, SIB1 carries Cell DTX parameter information and / or CellDRX parameter information, and SIB4 carries frequency point information. After receiving the broadcast information, the terminal performs cell reselection based on the frequency point information in the broadcast information.

[0127] Optionally, the frequency point information also includes frequency point indication information corresponding to each frequency point, which indicates whether the frequency point supports the first target QoS flow. Thus, if the terminal does not support the first target QoS flow, the terminal can select a frequency point that does not support the first target QoS flow during cell reselection; if the terminal supports the first target QoS flow, the terminal can select a frequency point that supports the first target QoS flow during cell reselection.

[0128] Optionally, the first information also includes prohibition indication information for each cell, which is used to indicate whether access is prohibited in that cell.

[0129] Optionally, the network device is an access network device, which schedules data for the target service based on Cell DTX parameter information and / or CellDRX parameter information. When a terminal switches from a source access network device to a destination access network device, the source access network device sends frequency point information and / or prohibition indication information corresponding to each cell to the destination access network device to prevent the terminal from switching to a prohibited cell or a frequency point that does not support the corresponding function.

[0130] Optionally, if the source access network device and the destination access network device have an Xn interface, then the source access network device and the destination access network device transmit frequency point information and / or prohibition indication information corresponding to each cell through the Xn interface. If the source access network device and the destination access network device do not have an Xn interface, then the source access network device sends the frequency point information and / or the prohibition indication information corresponding to each cell to the core network device, and the core network device sends the frequency point information and / or the prohibition indication information corresponding to each cell to the destination access network device.

[0131] Optionally, the terminal supports Cell DTX parameter information and / or Cell DRX parameter information. The system information sent by the network device to the terminal includes SIB1 and MIB, for a specific serving cell:

[0132] If the MIB indicates that access to the serving cell is permitted, and the SIB1 does not indicate whether access to the serving cell is permitted, then the terminal may access the serving cell.

[0133] If the prohibition indication information in the MIB indicates that access to the serving cell is permitted, and the indication information carried by SIB1 indicates that access to the serving cell is permitted, or carries Cell DTX parameter information and / or Cell DRX parameter information, then the terminal may access the serving cell.

[0134] If the MIB indicates that access to the serving cell is prohibited, and the SIB1 does not indicate whether access to the serving cell is permitted or the indicated information it carries indicates that access to the serving cell is permitted, then the terminal is prohibited from accessing the serving cell.

[0135] If the MIB indicates that access to the serving cell is prohibited, and the SIB1 carries an indication that access to the serving cell is permitted, or carries Cell DTX parameter information and / or Cell DRX parameter information, then the terminal may access the serving cell.
