Abstract
Description
Communication method and related apparatus
[0001] The present application claims priority from the Chinese patent application No. 202411110891.6 filed on August 13, 2024, and entitled "Communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[0002] The present application relates to the technical field of wireless communication, in particular to a communication method and related apparatus. BACKGROUND
[0003] In order to reduce the energy consumption of network equipment (such as a base station), a shutdown technology is usually used, for example, a cell discontinuous transmission (Cell DTX) technology. The network equipment only transmits downlink data to a terminal during a specified time period, and does not transmit downlink data during other time periods, that is, the network equipment discontinuously schedules data to achieve energy saving of the network equipment.
[0004] However, how to further improve the energy consumption of the network equipment by improving the use of the shutdown technology has become a problem to be solved. SUMMARY
[0005] The present application provides a communication method and related apparatus. The network equipment provides the terminal with Cell DTX information and / or Cell DRX information parameters associated with a QoS flow. When the service of the terminal matches the QoS flow, the shutdown technology is used. The use of the shutdown technology is improved to further reduce the power consumption of the network equipment.
[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:
[0007] In a first aspect, a communication method is provided. The method comprises: receiving first information, the first information comprising at least one of cell discontinuous transmission (Cell DTX) parameter information and cell discontinuous reception (Cell DRX) parameter information, the Cell DTX parameter information and / or the Cell DRX parameter information being associated with a first target quality of service (QoS) flow; and transmitting data corresponding to a target service according to the first information if the first target QoS flow meets a service quality requirement of the target service. By associating the first target QoS flow with the Cell DTX parameter information and / or the Cell DRX parameter information, the network device can schedule data of a service of the terminal according to the Cell DTX parameter information and / or the Cell DRX parameter information when the service of the terminal matches the first target QoS flow. By scheduling data of the service matching the first target QoS flow, the network device can schedule more data of the service according to the Cell DTX parameter information and / or the Cell DRX parameter information, thereby reducing power consumption of the network device and the terminal.
[0008] In some implementations of the first aspect, the first target QoS flow is different from a default QoS flow, and a priority of the first target QoS flow is higher than a priority of the default QoS flow; or the default QoS flow is set as the first target QoS flow. The network device can schedule more data according to the Cell DTX parameter information and / or the Cell DRX parameter information, thereby reducing power consumption of the terminal and the network device and improving energy saving.
[0009] In some implementations of the first aspect, the method further comprises: if the first target QoS flow does not meet the service quality requirement of the target service, sending second information to the network device, the second information being used to indicate that the first target QoS flow does not meet the service quality requirement of the target service. For a terminal in a connected state, after the terminal receives the first information, if the terminal does not allow to use the Cell DTX parameter information and / or the Cell DRX parameter information associated with the first target QoS flow, i.e., the first target QoS cannot meet the service quality requirement of the target service of the terminal, the terminal can send the second information to the network device, so that the network device makes a decision according to the second information, for example, the network side can establish a new QoS flow, carries the target service through the new QoS flow, or triggers a handover process of the terminal to switch the terminal to a base station supporting the target service.
[0010] In some implementations of the first aspect, the first information is carried in system information, and the method further comprises:
[0011] The terminal sends third information to the network device in a random access procedure or a radio resource control (RRC) connection procedure, and the third information is used to request adjustment of the Cell DTX parameter information and / or the Cell DRX parameter information. After receiving the first information, if the terminal supports the first target QoS flow, i.e., the first target QoS flow can meet the service quality requirement of the target service of the terminal, the terminal further sends the third information to the network device. For example, the third information includes the periodicity information of the Cell DTX, and the periodicity of the Cell DTX can be requested to be adjusted through the third information. In this way, after the terminal receives the first information, the Cell DTX parameter information and / or the Cell DRX parameter information are adjusted through the third information sent to the network device, so as to realize the negotiation between the terminal and the network device on the Cell DTX parameter information and / or the Cell DRX parameter information.
[0012] In some implementations of the first aspect, in a case where the first target QoS flow meets the service quality requirement of the target service, the transmitting the data corresponding to the target service according to the first information comprises: in a case where a tolerable scheduling delay of the target service is greater than or equal to a scheduling delay threshold, transmitting the data corresponding to the target service according to the first information, the scheduling delay threshold being determined based on the periodicity of the Cell DTX and / or the periodicity 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 as the relationship between the tolerable scheduling delay of the target service and the scheduling delay threshold, more data can be scheduled by the network device on the basis that the first target QoS flow can meet the service quality requirement of the target service of the terminal, so as to reduce the power consumption of the terminal and the network device and improve energy saving.
[0013] In some implementations of the first aspect, the first information is carried in system information, and the method further comprises: in a case where the serving cell cannot meet the service quality requirement of the target service, performing cell reselection according to the target service. In this way, the cell reselected can meet the service quality requirement of the target service.
[0014] In some implementations of the first aspect, the first information further comprises frequency point information, and the performing cell reselection according to the target service comprises: performing cell reselection according to the frequency point information and the target service. In this way, the frequency point reselected can meet the service quality requirement of the target service.
[0015] In some implementations of the first aspect, the system information comprises indication information, and the indication information is used to indicate that the terminal accesses the serving cell.
[0016] In some implementations of the first aspect, the priority of the first target QoS flow is set to be higher than the priority of the at least one dedicated QoS flow.
[0017] In a second aspect, a communication system is provided, the communication system comprising a network device and a terminal;
[0018] The network device sends first information to the terminal, the first information comprising at least one of cell discontinuous transmission (Cell DTX) parameter information and cell discontinuous reception (Cell DRX) parameter information, the Cell DTX parameter information and / or the Cell DRX parameter information being associated with a first target quality of service (QoS) flow;
[0019] The terminal receives the first information sent by the network device, and transmits data corresponding to a target service according to the first information if the first target QoS flow meets a quality of service requirement of the target service.
[0020] In a third aspect, a communication apparatus is provided, comprising a memory comprising computer readable instructions, and a processor in communication with the memory, the processor configured to execute the computer readable instructions to cause the communication apparatus to perform any of the communication methods of the first aspect.
[0021] In a fourth aspect, a computer readable storage medium is provided, comprising a program or instructions which, when executed by a processor, implement any of the communication methods of the first aspect.
[0022] In a fifth aspect, a chip is provided, comprising a processor configured to call and run instructions stored in a memory, so that a communication apparatus in which the chip is installed performs any of the communication methods of the first aspect.
[0023] In a sixth aspect, a computer program product is provided, comprising instructions which, when executed by a computer, implement any of the methods of the first aspect.
[0024] The beneficial effects brought by each possible implementation of the communication method provided in the second aspect, the communication apparatus 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 the present application can be referred to the description of the various possible implementations in the first aspect, which will not be repeated here.

[0034] The technical solutions in the present application will be described below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present specification, not all.
[0035] In a communication system, especially in a 5G communication system, terminal energy saving and network device (e.g. base station) energy saving are of great significance. At present, for network devices, Cell DRX can be used to receive data and / or Cell DTX can be used to transmit data, and by using the corresponding shutdown technology, the energy saving of the network device can be realized.
[0036] As shown in FIG. 1, FIG. 1 is a schematic diagram of a Cell DRX cycle. As shown in FIG. 1, cell 1 adopts a periodic Cell DRX configuration, and the DRX cycle includes an active time period (Cell DRX on) and an inactive time period (Cell DRX off). In the time period corresponding to Cell DRX on, the network device transmits downlink service with the terminal; in the time period corresponding to Cell DRX off, the network device stops transmitting downlink service with the terminal. The longer the time period corresponding to Cell DRX off, the longer and deeper the shutdown time and depth that the network device can take, and the better the energy saving effect can be obtained. How to reduce the energy consumption of the network device by improving the shutdown time and depth.
[0037] Among them, the quality of service (Quality of Service, QoS) plays a crucial role in the communication system, especially in resource-limited environments such as wireless networks, broadband networks and data center networks. The goal of QoS is to ensure that network resources can be effectively allocated to different applications and services to meet the different needs of various businesses for network performance. In the 5G network, QoS flow (QoS Flow) is an important concept to achieve QoS. Compared with the EPS bearer (EPS Bearer) in the 4G / LTE network, the QoS flow of 5G provides more fine-grained QoS control. In the 5G network, the QoS flow is managed by the core network (such as 5GC) and the access network (such as gNB) in coordination. 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. That is, QoS flow is used to guarantee the quality of service of different businesses and applications. According to its characteristics and application scenarios, QoS flow can be divided into two categories: default QoS flow (Default QoS Flow) and dedicated QoS flow (Dedicated QoS Flow). The default QoS flow is a QoS flow automatically established when the UE (User Equipment) is attached to the 5G network. It is the default channel for providing basic connection and data transmission services for the UE, and is usually used to carry those businesses that have no special QoS requirements, such as web browsing, email, etc. The dedicated QoS flow is a QoS flow specially established for a specific business or application, aiming to provide customized QoS guarantee. The establishment of this type of QoS flow usually requires additional signaling interaction between the network and the UE to negotiate and confirm specific QoS parameters.
[0038] Based on the above problems, the embodiment of the application provides a communication method, by associating the Cell DTX parameter information and / or the Cell DRX parameter information with the target QoS flow, so that when the user's business data matches the target QoS flow, the network side device schedules the data corresponding to the target business according to the Cell DTX parameter information and / or the Cell DRX parameter information. Through the network device, more data corresponding to the business can be scheduled according to the Cell DTX parameter information and / or the Cell DRX parameter information, so as to improve the energy saving performance of the network side device.
[0039] Next, some of the nouns involved in the embodiments of the application will be introduced.
[0040] (1) Cell DTX
[0041] Cell DTX is a mechanism for network device to send data for energy saving. Based on the Cell DTX mechanism, a DTX cycle of a cell provided by a network device includes an active time period and an inactive time period. In the active time period of the DTX cycle of the cell, the network device sends specific indication information (e.g. unicast scheduling information) or downlink data on the cell to terminals in the signal coverage of the cell. In the inactive time period of the DTX cycle of the cell, the network device does not send specific indication information (e.g. unicast scheduling information) or downlink data on the cell. That is, the network device can concentrate sending data on the cell in the active time period by the Cell DTX mechanism, and the network device associated with the cell such as a base station enters a sleep state and does not send indication information or downlink data related signals in the inactive time period, so as to save power consumption.
[0042] (2) Cell DRX
[0043] Cell DRX is a mechanism for network device to receive data for energy saving. Based on the Cell DRX mechanism, a DRX cycle of a cell provided by a network device includes an active time period and an inactive time period. In the active time period of the DRX cycle of the cell, the network device receives uplink signals sent by terminals in the signal coverage of the cell on the cell. In the inactive time period of the DRX cycle of the cell, the network device does not receive uplink signals on the cell. That is, the network device can concentrate receiving uplink signals in the active time period of the DRX cycle of the cell by the Cell DRX mechanism, and the cell enters a sleep state and does not receive uplink signals in the inactive time period, so as to save power consumption.
[0044] Figure 2 is a schematic diagram of the architecture of a communication system 1000 to which embodiments of the present application are applied. As shown in Figure 2, the communication system includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 2, collectively referred to as 110), and can further include at least one terminal (e.g., 120a-120j in Figure 2, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 2). The terminals 120 are wirelessly connected to the RAN nodes 110. Terminals and terminals, and RAN nodes and RAN nodes, can be connected to each other by wire or wirelessly. The communication system 1000 can further include a core network 200. The RAN nodes 110 are connected to the core network 200 by wire or wirelessly. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network devices and the logical functions of the RAN nodes. The communication system 1000 can further include the Internet 300.
[0045] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, and a future wireless access system defined in the 3rd generation partnership project (3GPP), or a WiFi system. The RAN 100 can further include two or more different wireless access systems. The RAN 100 can also be an open RAN (O-RAN).
[0046] A RAN node, also referred to as a radio access network device, RAN entity or access node, is configured to help a terminal to access to a communication system over the air. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system or an access node in a WiFi system. The RAN node can be a macro base station (e.g. 110a in FIG. 2), a micro base station or an indoor station (e.g. 110b in FIG. 2), a relay node or a donor node.
[0047] In another application scenario, a terminal can access to a communication system over the air by cooperation of a plurality of RAN nodes, each of which implements part of functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU) or a radio unit (RU). Here, the CU implements functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of a base station, and can further implement a function of a service data adaptation protocol (SDAP). The DU implements functions of a radio link control layer and a medium access control (MAC) layer of a base station, and can further implement part of functions or all functions of a physical layer. For details of the protocol layers, reference can be made to relevant technical specifications of 3GPP. The RU can be configured to implement functions of transceiving radio frequency signals. The CU and the DU can be two independent RAN nodes or integrated in a same RAN node, e.g. in a baseband unit (BBU). The RU can be included in a radio frequency device, e.g. in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes, i.e. a CU-control plane and a CU-user plane.
[0048] In different systems, the RAN node can have different names, for example, in the O-RAN system, the CU can be called an open CU (O-CU), the DU can be called an open DU (O-DU), and the RU can be called an open RU (O-RU).
[0049] In NR technology, a RAN node (for example, a gNB) can be composed of one gNB Centralized Unit (CU) and one or more gNB Distributed Units (DU). The gNB-CU and the gNB-DU are different logical nodes, which can be deployed on different physical devices or on the same physical device.
[0050] If the control plane and user plane separation architecture is considered, the gNB-CU can be further divided into a Central Unit-Control Plane (CU-CP) entity (or also referred to as a CU-CP node) and a Central Unit-User Plane (CU-UP) entity (or also referred to as a CU-UP node). Among them, the gNB-CU-CP is a control plane entity for providing signaling control, and the gNB-CU-UP is a user plane entity for providing transmission of terminal data. The gNB-CU-CP and the gNB-CU-UP are connected through an E1 interface, the gNB-CU-CP and the gNB-DU are connected through an F1-C interface, and the gNB-CU-UP and the gNB-DU are connected through an F1-U interface. The structure is shown in FIG. 3, which is a schematic diagram of the architecture of the separation of the gNB-CU-CP and the gNB-CU-UP.
[0051] For the architecture as shown in FIG. 3, the following characteristics also exist:
[0052] One gNB contains one gNB-CU-CP, multiple gNB-CU-UPs, and multiple gNB-DUs;
[0053] One DU can only be connected to one gNB-CU-CP;
[0054] One CU-UP can only be connected to one gNB-CU-CP;
[0055] One DU can be connected to multiple gNB-CU-UPs under the control of the same CU-CP;
[0056] One CU-UP can be connected to multiple gNB-DUs under the control of the same CU-CP.
[0057] It should be understood that FIG. 3 is only exemplary and should not impose any limitation on the architecture of the gNB. For example, under the CU-DU split and CP-UP split architecture, the gNB can include only one gNB-CU-UP, one gNB-CU-CP, one gNB-DU, or more gNB-CU-UPs and gNB-DUs. The present application does not limit here.
[0058] In one possible scenario, the RAN node can be the CU, DU, CU-CP, or CU-UP, etc. described above. The CU and DU can be separately arranged or included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, an active antenna unit (AAU), or a remote radio head (RRH).
[0059] The CU (or CU-CP and CU-UP), DU, or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an openRAN (O-RAN or ORAN) system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the sake of description, the CU, CU-CP, CU-UP, DU, and RU are taken as examples for description in the present application. Any of the CU (or CU-CP, CU-UP), DU, and RU in the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.
[0060] For example, FIG. 4 shows a schematic diagram of a RAN node. As shown in FIG. 4, the RAN node includes one or more CUs, one or more DUs, and one or more radio units (RUs). For the sake of clarity, only one CU, one DU, and one RU are shown in FIG. 4. The CU is configured to connect to a core network and one or more DUs. Optionally, the CU can have part of the functions of the core network. The CU can include a CU-CP and a CU-UP.
[0061] The CU and the DU can be configured according to protocol layer functions of the wireless network they implement: for example, the CU is configured to implement functions of a packet data convergence protocol (PDCP) layer and above protocol layers (e.g. a radio resource control (RRC) layer and / or a service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement functions of a protocol layer below the PDCP layer (e.g. a radio link control (RLC) layer, a media access control (MAC) layer, and / or a physical (PHY) layer, etc.). For another example, the CU is configured to implement functions of a protocol layer above the PDCP layer (e.g. the RRC layer and / or the SDAP layer), and the DU is configured to implement functions of a protocol layer below the PDCP layer (e.g. the RLC layer, the MAC layer, and / or the PHY layer, etc.).
[0062] When the CU includes a CU-CP and a CU-UP, the CU-CP is configured to implement control plane functions of the CU, and the CU-UP is configured to implement user plane functions of the CU. For example, the CU is configured to implement functions of the PDCP layer, the RRC layer, and the SDAP layer, the CU-CP is configured to implement functions of the RRC layer and control plane functions of the PDCP layer, and the CU-UP is configured to implement functions of the SDAP layer and user plane functions of the PDCP layer.
[0063] The CU-CP can interact with a network element in the core network configured to implement control plane functions. The network element in the core network configured to implement control plane functions can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The access and mobility function network element is configured to be responsible for mobility management in the mobile network, such as location updating of the terminal, registration of the terminal to the network, handover of the terminal, etc.
[0064] The CU-UP can interact with a network element in the core network configured to implement user plane functions. The network element in the core network configured to implement user plane functions, such as a user plane function (UPF) in a 5G system, is configured to be responsible for forwarding and receiving data in the terminal.
[0065] The configuration of the CU and the DU above is merely an example, and the CU and the DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have functions of more protocol layers, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to a service type or other system requirements, for example, according to a delay requirement. For example, functions that require a shorter delay requirement in processing time are arranged in the DU, and functions that do not require the delay requirement are arranged in the CU.
[0066] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in various ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the intermediate radio frequency side.
[0067] The RAN node in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of the software module and the hardware module, for example, the RAN node can be a server loaded with a corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form of the RAN node. For ease of description, a base station is taken as an example of the RAN node in the following description.
[0068] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. A terminal can be widely applied 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, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal.
[0069] A base station and a terminal can be in a fixed position or movable. A base station and a terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; can also be deployed on an airplane, balloon and artificial satellite. Embodiments of the present application do not limit the application scenarios of a base station and a terminal.
[0070] The roles of a base station and a terminal can be relative, for example, the helicopter or drone 120i in FIG. 2 can be configured as a mobile base station, which is a base station for those terminals 120j accessing to the wireless access network 100 through 120i; but for the base station 110a, 120i is a terminal, that is, 110a communicates with 120i through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a base station-to-base station interface protocol, in which case, 120i is also a base station relative to 110a. Therefore, a base station and a terminal can be collectively referred to as a communication apparatus, 110a and 110b in FIG. 2 can be referred to as a communication apparatus with base station function, and 120a-120j in FIG. 2 can be referred to as a communication apparatus with terminal function.
[0071] A base station and a terminal, a base station and a base station, a terminal and a terminal can communicate through licensed spectrum, can communicate through unlicensed spectrum, or can communicate through both licensed spectrum and unlicensed spectrum; can communicate through spectrum below 6 gigahertz (GHz), can communicate through spectrum above 6 GHz, or can communicate through both spectrum below 6 GHz and spectrum above 6 GHz. Embodiments of the present application do not limit the spectrum resources used for wireless communication.
[0072] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal, or by a device containing the functions of the terminal.
[0073] In the present application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection on a cell controlled by the base station. The cell with which the terminal establishes a wireless connection is called the service cell of the terminal. When the terminal communicates with the service cell, it will also be interfered by signals from neighboring cells.
[0074] Next, the transmission indication method provided by the embodiments of the present application will be explained in detail.
[0075] FIG. 5 is a flowchart of a communication method provided by an embodiment of the present application. The method can be applied in the communication system introduced above, and the network device in the following embodiments can be the RAN 100 in FIG. 2, or a core network device. Referring to FIG. 5, the method includes the following steps:
[0076] 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 including at least one of Cell DTX parameter information and Cell DRX parameter information, the Cell DTX parameter information and / or the Cell DRX parameter information being associated with a first target QoS flow.
[0077] Optionally, the Cell DTX parameter information includes Cell DTX related configuration parameters, for example, the Cell DTX parameter information includes one or more of a period of Cell DTX, a start time slot of a Cell DTX active period or an offset relative to a certain reference point, and a duration of each Cell DTX active period (or inactive period). The Cell DRX parameter information includes Cell DRX related configuration parameters, for example, can include one or more of a period of Cell DRX, a start time slot of a Cell DRX active period or an offset relative to a certain reference point, and a duration of each Cell DRX active period (or inactive period).
[0078] Optionally, the Cell DTX parameter information comprises first indication information, the first indication information being used for indicating whether the current cell supports the Cell DTX parameter information associated with the QoS flow; if the current cell supports the Cell DTX parameter information associated with the QoS flow, the first information further comprises the Cell DTX parameter information.
[0079] Optionally, the Cell DRX parameter information further comprises second indication information, the second indication information being used for indicating whether the current cell supports the Cell DRX parameter information associated with the QoS flow; if the current cell supports the Cell DRX parameter information associated with the QoS flow, the first information further comprises the Cell DRX parameter information.
[0080] Optionally, the Cell DTX parameter information and / or the Cell DRX parameter information is associated with the first target QoS flow; if the Cell DTX parameter information is associated with the first target QoS flow, if the service data of the terminal matches the first target QoS flow, the network device schedules the service data of the terminal according to the Cell DTX parameter information; if the Cell DRX parameter information is associated with the first target QoS flow, if the service data of the terminal matches the first target QoS flow, the network device schedules the service data of the terminal according to the Cell DRX parameter information.
[0081] 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, for example, the system information can be 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, the dedicated signaling carries the first information, that is, the first information is transmitted through the dedicated signaling, for example, the base station sends a radio resource control reconfiguration (RRC Reconfiguration) to the terminal, the RRC Reconfiguration carries the first information. Of course, the network device can also send non-access layer (Non-Access Stratum, NAS) information to the terminal, the NAS information carries the first information, that is, the first information is transmitted through the NAS information. It is easy to understand that the network device can transmit the first information through any one of the above three ways.
[0082] Optionally, if the first information includes multiple parameters, the network device can transmit the first information through at least two of the above three ways. For example, the first information includes the first indication information and the period of the Cell DTX, the network device sends the system broadcast carrying the first indication information, and if the current cell supports the Cell DTX parameter information associated with the QoS flow, the RRC Reconfiguration carries the period of the Cell DTX, that is, the period of the Cell DTX is transmitted through the RRC Reconfiguration. In this way, the network device transmits the first information to the terminal through the system broadcast and the dedicated signaling.
[0083] Optionally, if the network device (for example, the SMF) sends the NAS information carrying the first information to the terminal. Before the network device sends the NAS information to the terminal, the access network device sends the Cell DTX parameter information and / or the Cell DRX parameter information to the network device, and then after the network device receives the Cell DTX parameter information and / or the Cell DRX parameter information sent by the access network device, the network device sends the Cell DTX parameter information and / or the Cell DRX parameter information to the terminal.
[0084] S502, if the first target QoS flow meets the quality of service requirement of the target service, the terminal transmits the data corresponding to the target service according to the first information.
[0085] Optionally, after receiving the first information, the terminal is further configured to determine whether the terminal supports the first target QoS flow, for example, based on the configuration or capability of the terminal to determine whether the terminal supports the first target QoS flow. For another example, the terminal determines whether the tolerable scheduling delay of the target service is greater than the period of the Cell DTX or the period of the Cell DRX; if the tolerable scheduling delay of the target service of the terminal is greater than or equal to the period of the Cell DTX or the period of the Cell DRX, the terminal supports the first target QoS flow; if the tolerable scheduling delay of the target service of the terminal is less than the period of the Cell DTX or the period of the Cell DRX, the terminal does not support the first target QoS flow.
[0086] Optionally, since both the Cell DTX and the Cell DRX have an active period and an inactive period, during the inactive period, the data transmission between the terminal and the network device is suspended, and during the active period, the terminal and the network device can normally transmit data. Therefore, if the terminal supports a first target QoS flow associated with the Cell DTX parameter information and / or the Cell DRX parameter information, and the first target QoS flow meets the quality of service requirement of the target service of the terminal, the transmission of the data corresponding to the target service is performed through the first target QoS flow, and the data corresponding to the target service is scheduled by the network device according to the Cell DTX parameter information and / or the Cell DRX parameter information; if the first information includes the Cell DTX parameter information, the terminal transmits the data of the target service through the first target QoS flow during the active period of the Cell DTX; during the inactive period of the Cell DTX, the terminal suspends the transmission of the data of the target service; if the first information includes the Cell DRX parameter information, the terminal receives the data of the target service through the first target QoS flow during the active period of the Cell DRX; during the inactive period of the Cell DRX, the reception of the data of the target service is suspended.
[0087] In this way, the first target QoS flow is associated with the Cell DTX parameter information and / or the Cell DRX parameter information, and when the service of the terminal matches the first target QoS flow, the network device can schedule data according to the Cell DTX parameter information and / or the Cell DRX parameter information. By scheduling the data of the service matching the first target QoS flow by the network device, the network device can schedule more data of the service according to the Cell DTX parameter information and / or the Cell DRX parameter information, thereby reducing the power consumption of the terminal and the network device.
[0088] In some embodiments, a default QoS flow is set as the first target QoS flow. In this way, when the default QoS flow meets the quality of service requirement of the target service, i.e., the target service of the terminal matches the default QoS flow, the transmission of the data of the target service is performed through the default QoS flow. Since the default QoS is usually a non-GBR (Guaranteed Bit Rate) QoS flow, the requirement for resources is low. The default QoS flow usually does not guarantee a specific bit rate or low delay, and is suitable for services with low QoS requirement. The network device schedules the data of the target service carried by the default QoS flow according to the Cell DTX parameter information and / or the Cell DRX parameter information, and since the default QoS flow can carry more service data, the network device can schedule more data according to the Cell DTX parameter information and / or the Cell DRX parameter information, thereby reducing the power consumption of the terminal and the network device and improving the energy saving performance.
[0089] In some embodiments, when a Protocol Data Unit (PDU) session is created or modified, a network device configures a corresponding QoS rule for a terminal according to service requirements and network policies; the QoS rule includes a matching rule of a first target QoS flow and a matching rule of a default QoS flow, the matching rule of the first target QoS flow is different from the matching rule of the default QoS flow, that is, the first target QoS flow is different from the default QoS flow, and the priority of the first target QoS flow is higher than the priority of the default QoS flow. In this way, when performing QoS flow matching, the data of the target service is preferentially matched with the first target QoS flow because the priority of the first target QoS flow is higher than the priority of the default QoS flow, so that more data of the target service is 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 the Cell DTX parameter information and / or the Cell DRX parameter information, so as to reduce the power consumption of the terminal and the network device and improve the energy saving performance. The default QoS flow is the QoS flow with the lowest priority; when the data of the service of the terminal does not match the corresponding QoS flow, the data can be carried through the default QoS flow.
[0090] In some embodiments, since the first target QoS flow is associated with the Cell DTX parameter information and / or the Cell DRX parameter information, the priority of the first target QoS flow can be improved so that the first target QoS flow can be preferentially matched with the service of the terminal, so that more data of the service can be carried through the first target QoS flow, and then the network device schedules more data according to the Cell DTX parameter information and / or the Cell DRX parameter information, so as to reduce the power consumption of the terminal and the network device and improve the energy saving performance.
[0091] In some embodiments, the priority of the first target QoS flow is set to be higher than the priority of at least one dedicated QoS flow. The dedicated QoS flow refers to a flow with specific QoS parameters (such as delay, jitter, bandwidth, etc.) established to meet the requirements of a specific service or application. 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 improving the priority of the first target QoS flow, the first target QoS flow can be preferentially matched with the service of the terminal, and then the network device schedules more data according to the Cell DTX parameter information and / or the Cell DRX parameter information, so as to reduce the power consumption of the terminal and the network device and improve the energy saving performance.
[0092] In some embodiments, the priority of the first target QoS flow is higher than the priority of other QoS flows, i.e., the priority of the first target QoS flow is the highest. In this way, when performing QoS flow matching, the first target QoS flow has the highest priority, and the first target QoS flow is preferentially matched with the service of the terminal, so that more services can be carried through the first target QoS flow associated with the first information, and the network device schedules more data according to the Cell DTX parameter information and / or the Cell DRX parameter information, to further reduce the power consumption of the terminal and the network device, and improve the energy saving performance.
[0093] It is easy to understand that, 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 the matching rule of the first target QoS flow; for data corresponding to the target service, if the data meets the matching rule of the first target QoS flow, or the data matches the matching rule of the first target QoS flow, the first target QoS flow meets the quality of service requirement 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 matching of the uplink data and the QoS flow; if the data is downlink data corresponding to the target service, the network device (e.g., a User Plane Function (UPF)) performs matching of the uplink data and the QoS flow.
[0094] Optionally, the matching rule of the first target QoS flow includes a Packet Filter Set (PFS) in a data 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, the first target QoS flow meets the quality of service requirement of the target service, and the data of the target service can be carried through the first target QoS flow.
[0095] Optionally, the service scheduling delay is the main quality of service requirement of the target service, and the network device schedules the service data according to the Cell DTX and / or the Cell DRX, which can increase the transmission delay of the data corresponding to the target service. Therefore, the scheduling delay threshold can be determined through the Cell DTX parameter information and / or the Cell DRX parameter information, and the matching rule of the first target QoS flow is whether the tolerable scheduling delay of the target service is greater than or equal to the scheduling delay threshold. If the tolerable scheduling delay of the target service is greater than or equal to the scheduling delay threshold, the first target QoS flow meets the quality of service requirement of the target service; if the tolerable scheduling delay of the target service is less than the scheduling delay threshold, the first target QoS flow does not meet the quality of service requirement of the target service.
[0096] Optionally, the scheduling delay threshold corresponds to a data packet filter of the first target QoS flow, i.e. each data packet filter has a corresponding scheduling delay threshold, if the data of the target service matches the data 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, i.e. the first target QoS flow meets the service quality requirement of the target service; if the data of the target service does not match the data packet filter, the tolerable scheduling delay of the target service is less than the scheduling delay threshold of the first target QoS flow, i.e. the first target QoS flow does not meet the service quality requirement of the target service.
[0097] Optionally, the filtering rule in the data packet filter corresponding to the first target QoS flow includes a five-tuple, and the five-tuple includes a source IP address, a destination IP address, a source port, a destination port and a protocol type. The data packet filter can formulate rules based on specific values or ranges of the five-tuple to determine which data should be allowed to pass, which should be blocked or specially processed. Since the scheduling delay threshold corresponds to the data packet filter of the first target QoS flow, the scheduling delay threshold corresponds to the five-tuple, i.e. each five-tuple has a corresponding scheduling delay threshold.
[0098] Optionally, if the first information includes Cell DTX parameter information, the Cell DTX parameter information includes a period of Cell DTX, and the scheduling delay threshold can be determined according to the period of Cell DTX.
[0099] Optionally, if the first information includes Cell DTX parameter information, the Cell DTX parameter information includes a period of Cell DTX, and the scheduling delay threshold can be determined according to the period of Cell DTX.
[0100] In some embodiments, the period of Cell DTX or the period of Cell DRX can be set as the scheduling delay threshold. Of course, after obtaining the period of Cell DTX or the period of Cell DRX, the efficiency of the scheduling algorithm used and the delay of the current network can be obtained; then the corresponding scheduling delay threshold is determined based on the period of Cell DTX or the period of Cell DRX, the efficiency of the scheduling algorithm and the delay of the current network.
[0101] In some embodiments, the scheduling delay threshold can be determined by the terminal, for example, the Cell DRX parameter information comprises a cycle of the Cell DRX, and the terminal determines the scheduling delay threshold according to the cycle of the Cell DRX. If the Cell DTX parameter information comprises a cycle of the Cell DTX, the terminal determines the scheduling delay threshold according to the cycle of the Cell DTX. The scheduling delay threshold can also be determined by the network device, for example, if the first information further comprises the scheduling delay threshold, the network device determines the scheduling delay threshold according to the cycle of the Cell DRX and / or the cycle of the Cell DTX.
[0102] FIG. 6 is a flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 6, the method comprises the following steps:
[0103] S601, the network device sends first information to the terminal.
[0104] The content and sending manner of the first information can refer to S501, which will not be described here.
[0105] S602, the terminal sends second information to the network device, and the second information is used to indicate that the first target QoS flow does not meet the service quality requirement of the target service.
[0106] Optionally, for the terminal in the connected state, after the terminal receives the first information, if the terminal does not allow to use the Cell DTX parameter information and / or the Cell DRX parameter information associated with the first target QoS flow, i.e., the first target QoS cannot meet the service quality requirement of the target service of the terminal, the terminal can send the second information to the network device, so that the network device makes a decision according to the second information, for example, the network side can establish a new QoS flow, carries the target service through the new QoS flow, or triggers the terminal to switch to a base station supporting the target service.
[0107] Optionally, the terminal determines the network performance index based on the service quality requirement of the target service, for example, signal quality, delay, packet loss rate, etc.; then defines a measurement event based on the network performance index; for example, if the delay is greater than the tolerable delay of the service, the measurement event is triggered, and the measurement result (for example, the second information) is sent to the network device for decision by the network side.
[0108] In some embodiments, after the terminal in the connected state receives the first information, if the terminal does not allow to use the Cell DTX parameter information and / or the Cell DRX parameter information associated with the first target QoS flow, and the terminal can obtain the QoS parameter of the second target QoS flow, the terminal sends the QoS parameter of the second target QoS flow to the network device, for requesting the network device to establish the second target QoS flow according to the QoS parameter of the second target QoS flow, and the second target QoS flow can meet the quality of service requirement of the target service of the terminal. If the terminal cannot obtain the QoS parameter of the second target QoS flow, the terminal sends the second information to the network device.
[0109] Optionally, if the first target QoS flow is a default QoS flow, and the priority of the first target QoS flow is higher than the priority of at least one dedicated QoS flow, i.e., there is no default QoS flow as the "bottom line" QoS flow, if the target service of the terminal does not find a target QoS flow matched therewith, the terminal can send the second information to the network device, so that the network device creates a new QoS flow or triggers the handover of the terminal.
[0110] Optionally, the second target QoS flow has associated Cell DTX parameter information and / or Cell DRX parameter information. In this way, after the second target QoS flow is established and the second target QoS flow meets the quality of service requirement of the target service of the terminal, the data of the target service can be transmitted through the second target QoS flow, and the network device schedules the data of the target service according to the Cell DTX parameter information and / or the Cell DRX parameter information associated with the second target QoS flow, thereby reducing the power consumption of the network device and the terminal.
[0111] Optionally, the Cell DTX parameter information and / or the Cell DRX parameter information associated with the second target QoS flow is different from the Cell DTX parameter information and / or the Cell DRX parameter information associated with the first target QoS flow, for example, the Cell DTX cycle associated with the second target QoS flow is less than the Cell DTX cycle of the first target QoS flow.
[0112] FIG. 7 is a flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 7, the method includes the following steps:
[0113] S701, the network device sends first information to the terminal;
[0114] The content and sending manner of the first information can refer to S501, which will not be described here.
[0115] S702, the terminal sends third information to the network device, and the third information is used to request to adjust the Cell DTX parameter information and / or the Cell DRX parameter information.
[0116] Optionally, after receiving the first information, if the terminal supports the first target QoS flow, i.e., the first target QoS flow can meet the service quality requirement of the target service of the terminal, the terminal is further configured to send third information to the network device. For example, the third information includes the periodic information of the Cell DTX, and the terminal can request to adjust the periodic of the Cell DTX through the third information. In this way, after the terminal receives the first information, the terminal sends the third information to the network device, and adjusts the Cell DTX parameter information and / or the Cell DRX parameter information through the third information, so as to realize the negotiation between the terminal and the network device on the Cell DTX parameter information and / or the Cell DRX parameter information.
[0117] Optionally, after receiving the third information sent by the terminal, the network device sends fourth information to the terminal, and the fourth information includes the updated Cell DTX parameter information and / or the updated Cell DRX parameter information. In this way, through the interaction between the network device and the terminal, the update of the Cell DTX parameter information and / or the Cell DRX parameter information associated with the first target QoS flow is realized.
[0118] Optionally, after receiving the third information sent by the terminal, if the network device determines that the terminal triggers the frequency point switching condition according to the third information, for example, the third information requests to update the periodic of the Cell DTX, and the current frequency point cannot meet the updated periodic of the Cell DTX, the network device sends switching information to the terminal, and the switching information is used to instruct the terminal to switch to a new frequency point.
[0119] In some embodiments, if the UE is in a non-connected state, wherein the non-connected state includes an idle state and an inactive state, since there is no stable connection between the terminal and the network device, the terminal in the non-connected state receives the first information through system information. Of course, if the first information includes multiple parameter information, for example, the first information includes the first indication information and the periodic of the Cell DTX, the system information carries at least one parameter information, and the network device sends other parameter information to the terminal in or after the user random access process.
[0120] In some embodiments, the first information is carried in system information, and the method further comprises: sending, to the network device, third information in a random access procedure or a radio resource control (RRC) connection procedure, the third information being used to request adjustment of the Cell DTX parameter information and / or the Cell DRX parameter information. In this way, for a terminal in an unconnected state, after the terminal receives the system information including the first information, if the terminal supports the first information, the terminal can send the third information to the network device in the random access procedure or the RRC connection procedure, and the terminal and the network device negotiate the Cell DTX parameter information and / or the Cell DRX parameter information through the third information.
[0121] Optionally, the terminal in the unconnected state receives the system information sent by the network device, and the system information further includes indication information used to indicate that the terminal accesses a serving cell, and if the terminal supports the first target QoS flow, the terminal can access the serving cell. For example, the indication information is used to indicate resources and configurations of a random access channel (RACH), such as grouping and sequences of preambles, a size of a random access response window, and the like. The terminal initiates a random access procedure according to the indication information to access the serving cell.
[0122] Optionally, if the terminal sends the third information to the network device in the random access procedure, the third information is carried in a random access request message (Msg1) or a random access completion message (Msg3). For example, the third information is carried in a media access control element (MAC CE) in the Msg3.
[0123] Optionally, if the terminal sends the third information to the network device in the RRC connection procedure, the third information is carried in an RRC connection request, and the terminal sends the RRC connection request and the Msg3 to the network device together.
[0124] In some embodiments, if the terminal is in an unconnected state and a serving cell does not meet a quality of service requirement of a target service, the terminal can perform cell reselection according to the target service, so that a serving cell accessed after the cell reselection can meet the quality of service requirement of the target service of the terminal.
[0125] Optionally, if a serving cell to be accessed cannot provide a service meeting a quality of service requirement of a service of the terminal, the terminal sets the serving cell to be accessed as a forbidden access (for example, sets a state of the cell as “bar”), so as to avoid that the user selects the serving cell again after cell reselection.
[0126] Optionally, the first information further comprises frequency point information, and the terminal performs cell reselection according to the frequency point information and the target service, wherein the frequency point information is a frequency point recommended for the terminal to access or a frequency point forbidden for the terminal to access; of course, the frequency point can also be a new frequency point, i.e., a frequency point different from the frequency point of the current serving cell, so that the terminal can perform inter-frequency reselection according to the frequency point information.
[0127] For example, in the broadcast information sent by the network device, the SIB1 carries the Cell DTX parameter information and / or the Cell DRX parameter information, and the SIB4 carries the frequency point information, and after the terminal receives the broadcast information, the terminal performs cell reselection according to the frequency point information in the broadcast information.
[0128] Optionally, the frequency point information further comprises frequency point indication information corresponding to each frequency point, and the frequency point indication information is used to indicate whether the frequency point supports the first target QoS flow. In this way, 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 when performing 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 when performing cell reselection.
[0129] Optionally, the first information further comprises forbidden indication information corresponding to each cell, and the forbidden indication information is used to indicate whether the cell is forbidden to access.
[0130] Optionally, the network device is an access network device, and the access network device schedules data of the target service according to the Cell DTX parameter information and / or the Cell DRX parameter information. When the terminal switches from a source access network device to a target access network device, the source access network device sends the frequency point information and / or the forbidden indication information corresponding to each cell to the target access network device, so as to avoid the terminal switching to a cell that is forbidden to access or a frequency point that does not support a corresponding function.
[0131] Optionally, if the source access network device and the target access network device have an Xn interface, the source access network device and the target access network device transmit the frequency point information and / or the forbidden indication information corresponding to each cell through the Xn interface. If the source access network device and the target access network device do not have an Xn interface, the source access network device sends the frequency point information and / or the forbidden indication information corresponding to each cell to a core network device, and the core network device sends the frequency point information and / or the forbidden indication information corresponding to each cell to the target access network device.
[0132] Optionally, the terminal supports the Cell DTX parameter information and / or the Cell DRX parameter information, and the system information sent by the network device to the terminal comprises an SIB1 and an MIB, and for a specific serving cell:
[0133] If the barring indication information in the MIB indicates that the terminal can access the serving cell, and the SIB1 does not indicate whether the terminal can access the serving cell, the terminal can access the serving cell;
[0134] If the barring indication information in the MIB indicates that the terminal can access the serving cell, and the SIB1 carries the indication information indicating that the terminal can access the serving cell or carries the Cell DTX parameter information and / or the Cell DRX parameter information, the terminal can access the serving cell.
[0135] If the barring indication information in the MIB indicates that the terminal is barred from accessing the serving cell, and the SIB1 does not indicate whether the terminal can access the serving cell or carries the indication information indicating that the terminal can access the serving cell, the terminal is barred from accessing the serving cell.
[0136] If the barring indication information in the MIB indicates that the terminal is barred from accessing the serving cell, and the SIB1 carries the indication information indicating that the terminal can access the serving cell or carries the Cell DTX parameter information and / or the Cell DRX parameter information, the terminal can access the serving cell.
