[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on February 8, 2024, with application number 202410177003.6 and application name "A Communication Method, Device and System", the entire contents of which are incorporated by reference into this application. Technical Field

[0004] In wireless communication systems, terminals support three radio resource control (RRC) states: RRC connected, RRC inactive, and RRC idle. Terminals can switch between different RRC states. For example, when there is no data transmission, the terminal can switch to the RRC inactive or RRC idle state. When there is data transmission, the terminal can switch to the RRC connected state. During the process of switching from the RRC inactive or RRC idle state to the RRC connected state, the terminal needs to execute a series of processes to restore the RRC connection between the terminal and the access network device, resulting in a large delay and overhead caused by the terminal's RRC state switching.

[0063] In order to make the purpose, technical solutions and advantages of this application more clear, the application will be further described in detail below with reference to the accompanying drawings. The specific operation methods and functional descriptions in the method embodiments can also be applied to the device embodiments or system embodiments.

[0064] The various numbers and terms such as "first" and "second" used in the embodiments of this application are merely for convenience of description and are not intended to limit the scope of the embodiments of this application. The order of the sequence numbers of the above-mentioned processes does not necessarily indicate the order in which they are executed. The order in which the processes are executed should be determined by their functions and internal logic.

[0065] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. "Including at least one of A, B or C" can mean: including A; including B; including C; including A and B; including A and C; including B and C; including A, B and C.

[0066] FIG1 is a schematic diagram illustrating a possible, non-limiting system. As shown in FIG1 , a communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the Internet 300 is also included.

[0067] The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one terminal (e.g., 120a to 120j in FIG. 1 , collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in FIG. 1).

[0068] Terminal 120 can be connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or by wire. The core network device in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be a single physical device that integrates the logical functions of the core network device and the logical functions of the radio access network.

[0069] RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a fourth generation (4G) mobile communication system, a fifth generation (5G) mobile communication system, or a future-oriented evolution system, such as a sixth generation (6G) mobile communication system. RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0070] The RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. In the subsequent description of this application, unless otherwise specified, the term "access network equipment" is used. Multiple RAN nodes 110 in the communication system 10 can be of the same type or different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing the RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN nodes 110 and terminals 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0071] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), 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 may be a macro base station (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, a RAN node may also be a server, a wearable device, a vehicle or an onboard device. For example, an access network device in vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the embodiments of the present application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node in the embodiments of the present application may also be a logical node, a logical module, or software that can implement all or part of the functions of the RAN node.

[0072] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0073] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0074] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal 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 (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal can be a mobile phone, a head-mounted display device, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0075] The solutions provided in the embodiments of this application can be applied to 5G communication systems, 6G communication systems, integrated communication and perception systems, and even other communication systems that will evolve in the future, without limitation. In the following description, the communication between access network equipment and terminals is mainly used as an example. The solutions provided in the embodiments of this application can also be applied to other application scenarios, such as communication between base stations, communication between terminals, communication in the Internet of Vehicles, the Internet of Things, or the Industrial Internet, without limitation.

[0076] In one solution, a terminal supports three radio resource control (RRC) states: RRC_connected, RRC_idle, and RRC_inactive. Depending on data transmission requirements, the terminal can switch between these three RRC states. For example, when there is no data transmission, the terminal can switch to the RRC_idle or RRC_inactive state to reduce terminal power consumption. When there is data transmission, the terminal switches from the RRC_idle state to the RRC_connected state. For example, a terminal in the RRC_idle state must go through processes such as random access, RRC connection establishment, initial terminal context establishment, and RRC configuration before it can switch from the RRC_idle state to the RRC_connected state. Alternatively, a terminal can switch from the RRC_inactive state to the RRC_connected state. For example, a terminal in the RRC_inactive state must go through processes such as RRC connection recovery, terminal context acquisition, and RRC configuration before it can switch from the RRC_inactive state to the RRC_connected state. Switching between the three RRC states results in significant latency and energy consumption.

[0077] In view of this, an embodiment of the present application provides a communication method in which a terminal can switch between different modes according to different data transmission requirements. Since the terminal does not need to perform processes such as restoring the RRC connection between the terminal and the access network device during the mode switching process, the terminal reduces the delay and energy consumption overhead caused by the RRC state switching.

[0078] [Example 1]

[0079] As shown in FIG2 , the embodiment of the present application provides a flow chart, including:

[0080] Step 200: The terminal enters the first mode.

[0081] For example, the first mode is used to execute a first process, and the first process is used to establish a terminal context on the core network side and / or a terminal context on the access network side.

[0082] Step 210: The terminal switches to the second mode or the third mode.

[0083] In one possible implementation, the process of step 210 includes: the terminal switching from the first mode to the second mode or the third mode. For example, after completing the first mode, the terminal switches to the second mode or the third mode. For example, after completing the first mode, the terminal switches to the second mode by default. Alternatively, the terminal switches to the second mode or the third mode based on demand. For example, the terminal switches to the second mode based on a first requirement. The terminal switches to the third mode based on a second requirement. Alternatively, the access network device may trigger the terminal to switch modes. For example, the access network device determines that the terminal switches to the second mode or the third mode based on demand. The access network device sends indication information to the terminal, which may be referred to as fifth indication information. Upon receiving the indication information, the terminal switches to the second mode or the third mode according to the indication information. Specifically, the terminal may switch from the first mode to the second mode or the third mode. Optionally, in the description of this application, a requirement may also be referred to as a transmission requirement or a data transmission requirement. For example, the first requirement may also be referred to as a first transmission requirement or a first data transmission requirement, and the second requirement may also be referred to as a second transmission requirement or a second data transmission requirement.

[0084] In another possible implementation, after completing the first mode, the terminal switches to the second mode or the third mode. Thereafter, the terminal can switch between the second mode and the third mode. The process of step 210 includes: the terminal switches from the second mode to the third mode, or the terminal switches from the third mode to the second mode. The terminal can switch between the second mode and the third mode as needed. Alternatively, the access network device can trigger the terminal to switch modes. For example, the access network device sends an indication message to the terminal, and the indication message can be called the fifth indication message. The terminal switches to the second mode or the third mode according to the indication of the indication message. For example, the terminal switches from the second mode to the third mode, or the terminal switches from the third mode to the second mode, etc.

[0085] Through the above design, the terminal can switch between the second mode and the third mode as needed. During the mode switching process, there is no need to execute processes such as RRC connection establishment, thereby reducing the delay and overhead caused by RRC state switching.

[0086] It can be understood that in the process of Figure 2, the solution provided by the embodiment of the present application is described from the perspective of the terminal. If from the perspective of the access network device: the access network device can determine that the terminal switches to the second mode or the third mode, the second mode corresponds to the first requirement of the terminal, and the third mode corresponds to the second requirement of the terminal. The access network device communicates with the terminal according to the second mode or the third mode. For example, the access network device determines that the terminal switches to the second mode or the third mode, including: the access network device receives fourth indication information from the terminal, and the fourth indication information is used to indicate switching to the second mode or the third mode. Alternatively, the access network device can determine that the terminal switches to the second mode or the third mode according to demand. For the specific process, please refer to the description below.

[0087] It will be understood that in the above description, the transmission requirements between the terminal and the network include two types: a first requirement and a second requirement. The first requirement corresponds to the second mode, and the second requirement corresponds to the third mode. In other words, when the transmission requirement between the terminal and the network is the first requirement, the terminal can switch to the second mode. Alternatively, when the transmission requirement between the terminal and the network is the second requirement, the terminal can switch to the third mode. The above process is merely illustrative and does not limit the embodiments of this application. For example, the transmission requirements between the terminal and the network include N requirements, where N is an integer greater than 1. Based on the N requirements, the terminal can switch between M modes, where M is an integer greater than 1, and the values ​​of M and N can be equal or unequal. For example, if the value of N is equal to the value of M, the relationship between the requirements and the modes is one-to-one, with each requirement corresponding to one mode. Alternatively, if the value of N is greater than the value of M, the relationship between the requirements and the modes can be many-to-one or one-to-one. For example, multiple requirements can correspond to one mode. Alternatively, if the value of N is less than the value of M, the relationship between the requirements and the modes can be one-to-many or one-to-one. For example, a requirement corresponds to multiple modes. In the case where a requirement corresponds to multiple modes, the terminal is not limited to which mode among the multiple modes it switches to. For example, the terminal may switch to any one of the multiple modes. Alternatively, the terminal may switch to one of the multiple modes based on other factors.

[0088] Optionally, in the embodiment of the present application, according to different stages of the terminal, the terminal modes include three types: first mode, second mode and third mode. Specifically:

[0089] The first mode is the initialization phase after the terminal is powered on. During this phase, the terminal can complete initialization processes such as network selection, terminal registration, authentication, security negotiation, and terminal context establishment.

[0090] Second mode: No data transmission or small data transmission stage, supports terminal-specific configuration, network-wide configuration, mobility management, and uplink and downlink data transmission. See the detailed description below for details.

[0091] The third mode: During the large data transmission phase, the network provides dedicated configurations and can call on stronger terminal capabilities to achieve service transmission with stronger quality of service (QoS) guarantees.

[0092] It is understood that in the embodiments of the present application, there is no limitation on the names of "modes." For example, the first mode may also be referred to as mode 0; the second mode may also be referred to as mode 1 or default mode; and the third mode may also be referred to as mode 2, enhanced mode, or configurable mode.

[0093] It is understood that switching between the first mode, the second mode, or the third mode is possible. For example, as shown in Figure 3, after the terminal completes the first mode, the terminal may switch to the second mode by default. Alternatively, it may switch to the second mode or the third mode as needed. Thereafter, the terminal switches between the second mode and the third mode. It is understood that the process of the terminal switching between the second mode and the third mode may be triggered by the terminal as needed, or the access network device may trigger the terminal switching as needed.

[0094] Optionally, the second and third modes can fall back to the first mode. That is, the terminal can switch from the second or third mode to the first mode. For example, when the network fails to obtain the terminal context and needs to re-establish the terminal context, the terminal can fall back from the second or third mode to the first mode.

[0095] The following is a detailed description of the embodiments of the present application.

[0096] 1. The terminal enters the first mode.

[0097] For example, after the terminal is powered on, it enters the first mode: executes the first process, which can be called the initialization process. The first process includes at least one of the following: frequency scanning, terminal selection of access network equipment and service cells, random access, transmission resource determination, or interaction of security parameters between the terminal and the core network equipment and access network equipment. The interaction process of security parameters between the terminal and the core network equipment and access network equipment includes processes such as authentication and security negotiation. For example, after the terminal is powered on, the terminal can execute the first process, which includes at least one of the following:

[0098] Frequency sweeping to synchronize the terminal with the network downlink.

[0099] Selecting an access network device and a serving cell. For example, the terminal may select a public land mobile network (PLMN) and an access network device. Furthermore, the terminal may select a cell from among the cells provided by the access network device to communicate with the access network device. This cell may be referred to as a serving cell. For example, the terminal may receive cell signals from at least one cell to determine the cell signal quality. The terminal determines the serving cell based on the cell signal quality. For example, the terminal may select the cell with the best cell signal quality from among at least one cell as the serving cell.

[0100] Random access. For example, a terminal can perform a random access procedure to establish a connection with an access network device. After the connection is established, the terminal and the access network device can conduct normal uplink and / or downlink communications.

[0101] The transmission resources are determined. For example, it may include transmission configuration and transmission resources. In the first mode, the terminal and the access network device may transmit control plane signaling messages. For example, the signaling message includes a signaling radio bearer (SRB) 0 message and / or an SRB1 message, etc. The signaling message may carry a non-access stratum (NAS) message. The radio bearer corresponding to the signaling message may be configured by the access network device to the terminal, or predefined, or preconfigured, etc., without limitation. Furthermore, the transmission resources (also called time-frequency resources) of the signaling message may be configured by the access network device, for example, the access network device configures the corresponding transmission resources for the terminal through a system message. Alternatively, the transmission resources may be predefined, such as those specified by the protocol or specified by the protocol for the transmission of signaling messages, or the transmission resources may be preconfigured, etc., without limitation. Since the transmission resources of the signaling message are configured through system messages, predefined or preconfigured, etc., the transmission resources corresponding to different terminals may be the same, and the transmission resources of different terminals may conflict.

[0102] For example, in the first mode, uplink and downlink data transmission of the terminal can be performed based on resource configuration or dynamic resource scheduling. Taking the transmission of signaling messages based on dynamic resource scheduling as an example: in a possible implementation method, the access network device can configure the transmission resources corresponding to the signaling message for the terminal through a downlink signal. Optionally, the downlink signal can be a low power downlink signal (LPDS). For example, the access network device indicates the transmission resources corresponding to the downlink signal to the terminal. This process can occur during the random access process or after the random access is completed, without limitation. The access network device sends a downlink signal to the terminal on the indicated transmission resource, and the terminal receives the downlink signal from the access network device on the indicated transmission resource. The downlink signal carries indication information of the transmission resource corresponding to the signaling message. Optionally, further, the downlink signal can also carry an indication for instructing the terminal to transmit the signaling message on the above-mentioned transmission resource. For example, the downlink signal also carries an indication for instructing the terminal to transmit SRB0 messages and SRB1 messages on the above-mentioned indicated transmission resources. Optionally, the downlink signal may be scrambled using an identifier of the corresponding terminal, for example, the identifier of the terminal may be a radio network temporary identifier (RNTI) of the terminal, thereby avoiding conflicts between downlink signals of different terminals. It is understood that during the random access process, the access network device may allocate an RNTI to the terminal.

[0103] The interaction of security parameters between the terminal and the core network device and the access network device. For example, the interaction process of security parameters between the terminal and the core network device includes: the terminal and the core network perform terminal authentication, contract information acquisition, security negotiation and other processes, and the core network establishes the context of the terminal. Optionally, in the above process, the terminal and the core network device can exchange necessary parameter information through NAS messages. The NAS message is carried in the SRB signaling between the terminal and the access network device and is transparently transmitted by the access network device. The interaction process of security parameters between the terminal and the access network device includes: the core network triggers the terminal context establishment process on the access network side. For example, in the terminal context establishment process on the access network side, the terminal and the access network device can exchange the following information: core network identification, security parameters, terminal authentication information, or basic terminal capabilities (such as security capabilities), etc.

[0104] 2. The terminal switches from the first mode to the second mode or the third mode.

[0105] For example, after completing the relevant processes of the first mode, the terminal switches to the second mode by default. Alternatively, after completing the relevant processes of the first mode, the terminal may switch to the second mode or the third mode as needed. Alternatively, the access network device may send fifth indication information to the terminal, where the fifth indication information is used to instruct the terminal to switch from the first mode to the second mode or the third mode. The terminal receives the fifth indication information and switches from the first mode to the second mode, or from the first mode to the third mode, according to the instruction of the fifth indication information.

[0106] 3. The terminal switches between the second mode and the third mode.

[0107] For example, the terminal switches from the second mode to the third mode, or the terminal switches from the third mode to the second mode, etc. The terminal can switch from the second mode to the third mode, or from the third mode to the second mode, as needed. Alternatively, the access network device can send fifth indication information to the terminal, instructing the terminal to switch to the second mode or the third mode.

[0108] The above description describes how a terminal can trigger a switch from a first mode to a second mode or a third mode. Alternatively, a switch between the second and third modes can be triggered. Alternatively, an access network device can trigger a terminal to switch to the second or third mode. The following describes the process of a terminal triggering a mode switch and the process of an access network device triggering a terminal mode switch.

[0109] For example, the process of terminal triggering handover includes:

[0110] For example, the terminal switches to the second mode or the third mode based on a requirement. Optionally, the requirement includes the first requirement or the second requirement. Furthermore, the requirement may include other requirements, such as the third requirement, without limitation. In one possible implementation, the terminal switches to the second mode based on the first requirement. Alternatively, the terminal switches to the third mode based on the second requirement. Optionally, the terminal may determine the first requirement or the second requirement based on the terminal's transmission conditions.

[0111] For example, the terminal may obtain the terminal's transmission status. Optionally, the terminal's transmission status includes at least one of the following: the terminal's service type, the terminal's service data volume, the QoS corresponding to the terminal's service data, or a transmission parameter of the terminal's service data.

[0112] In one possible implementation, the terminal may obtain the service type of the terminal. For example, the upper layer of the terminal (such as the application layer) may indicate the service type of the terminal to the access stratum (AS). When the service type of the terminal is the first type, the terminal switches to the second mode. At this time, the first requirement includes that the service type of the terminal is the first type. For example, the first type may include small packet transmission services, small traffic services, or periodic services, etc. Alternatively, when the service type of the terminal is the second type, the terminal switches to the third mode. At this time, the second requirement includes that the service type of the terminal is the second type. For example, the second service type may be real-time broadband communication (RTBC), ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), etc. Alternatively,

[0113] The terminal can obtain the service data volume of the terminal. For example, the service data volume of the terminal includes: the service data volume cached by the AS layer of the terminal, or the service data volume indicated by the application layer of the terminal to the AS layer. When the service data volume of the terminal is less than the first threshold, the terminal switches to the second mode. At this time, the first requirement includes that the service data volume of the terminal is less than the first threshold. Or, when the service data volume of the terminal is greater than or equal to the first threshold, the terminal switches to the third mode. At this time, the second requirement includes that the service data volume of the terminal is greater than or equal to the first threshold. Optionally, the first threshold can be predefined, such as specified by the protocol, or configured to the terminal by the access network device. For example, after the terminal successfully accesses randomly, the access network device configures the first threshold for the terminal through the cell system message, etc. Or,

[0114] The terminal can obtain the Qos corresponding to the terminal's business data. For example, the Qos corresponding to the terminal's business data includes at least one of: the delay of the terminal's business data, the packet loss rate of the terminal's business data, or the transmission rate of the terminal's business data. Take the delay of the terminal's business data as an example: when the delay of the terminal's business data is greater than or equal to the second threshold, the terminal switches to the second mode. At this time, the first requirement includes that the delay of the terminal's business data is greater than or equal to the second threshold. Or, when the delay of the terminal's business data is less than the second threshold, the terminal switches to the third mode. At this time, the second requirement includes that the delay of the terminal's business data is less than the second threshold. Optionally, the second threshold can be predefined, such as defined by the protocol, or configured by the access network device to the terminal, etc., without limitation. Or,

[0115] The terminal can obtain transmission parameters for its service data. For example, the transmission parameters for the terminal's service data include at least one of the following: the arrival rate of the terminal's upper-layer service data, the air interface transmission rate, the bandwidth of the service data, or the latency of the service data. Taking the arrival rate of the terminal's upper-layer service data as an example, when the arrival rate of the terminal's upper-layer service data is less than a third threshold, the terminal switches to the second mode. In this case, the first requirement includes the arrival rate of the terminal's upper-layer service data being less than the third threshold. Alternatively, when the arrival rate of the terminal's upper-layer service data is greater than or equal to the third threshold, the terminal switches to the third mode. In this case, the second requirement includes the arrival rate of the terminal's upper-layer service data being greater than or equal to the third threshold. Optionally, the third threshold is predefined or configured for the terminal by the access network device, and is not subject to limitation. Alternatively, when the arrival rate of the terminal's upper-layer service data is less than the air interface transmission rate of the terminal, the terminal switches to the second mode. In this case, the first requirement includes the arrival rate of the terminal's upper-layer service data being less than the air interface transmission rate of the terminal. Alternatively, when the arrival rate of the terminal's upper-layer service data is greater than or equal to the air interface transmission rate of the terminal, the terminal switches to the third mode. At this time, the second requirement includes that the arrival rate of the terminal upper layer service is greater than or equal to the transmission rate of the terminal air interface.

[0116] Alternatively, in one possible implementation, the terminal may determine the demand using artificial intelligence (AI). For example, a first module may be deployed inside or outside the terminal, configured to predict the demand using AI. For example, the first module may include an AI model. For example, when the first module is deployed inside the terminal, the terminal may input the terminal's transmission status into the first module, and the output of the first module may include the demand. Alternatively, when the first module is deployed outside the terminal, the terminal may send the terminal's transmission status to the first module. The terminal's transmission status is input into the first module, and the output of the first module may include the demand. Of course, the demand output by the first module may be the first demand or the second demand. The first module sends third indication information to the terminal, indicating the demand output by the first module. It is understood that the demand output by the first module may specifically be the first demand or the second demand. If the demand output by the first module indicated by the third indication information is the first demand, the terminal switches to the second mode. Alternatively, if the demand output by the first module indicated by the third indication information is the second demand, the terminal switches to the third mode. It is understood that the output of the first module includes not only the requirements but also other AI analysis results, such as the mode configuration corresponding to the terminal in the second mode or the third mode. In one possible implementation, the first module may send all AI analysis results to the terminal.

[0117] It is understandable that the terminal acts as the transmitter of uplink data. In the above description, when the terminal determines the demand based on the terminal's transmission status, the terminal mainly considers: the transmission status of the uplink data. Optionally, the terminal acts as the receiver of downlink data. When determining the demand, the terminal may also consider the reception status of the downlink data. For example, the packet loss of the downlink data, or the amount of downlink data received within a period of time. That is to say, in this example, the transmission status of the terminal, in addition to the transmission status of the uplink data of the terminal mentioned above, also includes the reception status of the downlink data of the terminal.

[0118] Furthermore, in a scenario where the terminal triggers itself to switch to the second mode or the third mode, the terminal may notify the access network device to decide whether to switch to the second mode or the third mode. For example, the terminal sends fourth indication information to the access network device, and the access network device receives the fourth indication information from the terminal, where the fourth indication information is used to instruct the terminal to switch to the second mode or the third mode. The access network device may determine whether the terminal switches to the second mode or the third mode based on the fourth indication information.

[0119] Optionally, the access network device determines the configuration of the second mode or the third mode based on the fourth indication information and sends it to the terminal. Alternatively, the access network device sends an activation indication to instruct the terminal to activate the corresponding configuration of the second mode or the third mode.

[0120] In another possible implementation, the fourth indication information includes the configuration corresponding to the second mode or the third mode determined by the terminal, and the access network device communicates with the terminal in the second mode or the third mode based on the configuration indicated by the terminal in the fourth indication information.

[0121] For example, the process of triggering a handover by an access network device includes:

[0122] For example, the access network device may determine, based on demand, whether the terminal should switch to the second mode or the third mode. The access network device sends fifth indication information to the terminal, where the fifth indication information is used to instruct the terminal to switch to the second mode or the third mode. The terminal switches to the second mode or the third mode according to the fifth indication information.

[0123] In a possible implementation, the access network device may determine that the terminal switches to the second mode according to the first requirement; and the access network device may determine that the terminal switches to the third mode according to the second requirement.

[0124] In one possible implementation, the access network device may determine the transmission status of the terminal. The transmission status of the terminal may be counted by the access network device itself. For example, the transmission status of the terminal counted by the access network device includes: the arrival rate of service data, the transmission rate of the air interface, the bandwidth of service data, the delay of service data, or the QoS of service data. For example, the arrival rate of service data may refer to the arrival rate of uplink service data received by the access network device and / or the arrival rate of downlink service data received by the access network device; the access network device may determine the first requirement or the second requirement based on the transmission requirements of the terminal counted. And according to the first requirement, trigger the terminal to switch to the second mode; or, according to the second requirement, trigger the terminal to switch to the third mode, etc.

[0125] In another possible implementation, the core network device may notify the access network device of the transmission status of the terminal. For example, the core network device sends the sixth indication information to the access network device, and the access network device receives the sixth indication information from the core network device, and the sixth indication information is used to indicate the transmission status of the terminal. The access network device obtains the transmission status of the terminal based on the sixth indication information. For example, the transmission status of the terminal indicated by the core network device to the access network device, that is, the sixth indication information is used to indicate at least one of the following: the service type of the terminal, the data volume of the terminal's service, the QoS corresponding to the terminal's service data, or the transmission parameters of the service data (such as the bandwidth or delay of the service data, etc.). Further, the access network device determines the first requirement or the second requirement based on the transmission status of the terminal indicated by the access network device. And according to the first requirement, trigger the terminal to switch to the second mode; or, according to the second requirement, trigger the terminal to switch to the third mode, etc.

[0126] For example, the core network device may indicate the service type of the terminal to the access network device. Optionally, the service type of the terminal indicated by the core network device includes the service type of the downlink reaching the access network device indicated by the core network device. As previously mentioned, when the service type of the terminal is the first type, the access network device determines that the terminal switches to the second mode, and the fifth indication information sent by the access network device to the terminal is used to indicate switching to the second mode. Alternatively, when the service type of the terminal is the second type, the access network device determines that the terminal switches to the third mode, and the fifth indication information sent by the access network device to the terminal is used to indicate switching to the third mode. Alternatively,

[0127] The core network device may indicate the data volume of the terminal's service to the access network device. Optionally, the data volume of the terminal's service indicated by the core network device includes the downlink service data volume delivered to the terminal within the first time as indicated by the core network device. As mentioned above, when the data volume of the terminal's service is less than the first threshold, the access network device determines that the terminal switches to the second mode. Alternatively, when the data volume of the terminal's service is greater than or equal to the first threshold, the access network device determines that the terminal switches to the third mode. Alternatively,

[0128] The core network device may indicate the QoS corresponding to the service data of the terminal to the access network device. The access network device may determine whether the terminal switches to the second mode or the third mode based on the QoS corresponding to the service data of the terminal. Alternatively,

[0129] The core network device may indicate the service data transmission parameters of the terminal to the access network device. For example, the service data transmission parameters indicated by the core network device may be the transmission bandwidth requirement or transmission delay requirement of the downlink service data, etc. For example, when the transmission bandwidth requirement of the downlink service data is less than the fourth threshold, or the transmission delay requirement of the downlink service data is greater than or equal to the fifth threshold, the access network device may determine that the terminal switches to the second mode. Alternatively, when the transmission bandwidth requirement of the downlink service data is greater than or equal to the fourth threshold, or the transmission delay of the downlink service data is less than the fifth threshold, the access network device may determine that the terminal switches to the third mode.

[0130] Alternatively, in one possible implementation, the access network device may determine the requirement using an AI approach. For example, a first module is deployed internally or externally to the access network device, and the first module is configured to determine the requirement using an AI approach. For example, the first module includes an AI model. For example, when the first module is deployed externally to the access network device, the access network device sends the terminal's transmission status to the first module. The terminal's transmission status is input to the first module, and the first module outputs the requirement. Of course, the requirement output by the first module may be the first requirement or the second requirement. The first module sends seventh indication information to the access network device, and the access network device receives the seventh indication information from the first module. The seventh indication information indicates the requirement output by the first module. It is understood that when the requirement indicated by the seventh indication information is the first requirement, the access network device determines that the terminal switches to the second mode. Alternatively, when the requirement indicated by the seventh indication information is the second requirement, the access network device determines that the terminal switches to the third mode. Optionally, the access network device may periodically send the terminal's transmission status to the first module for model inference, and further perform mode switching based on the model inference results of the first module to better meet data transmission requirements.

[0131] It is understandable that the information sent by the access network device to the first module for model inference may be the transmission status of the terminal. Alternatively, it may be other information in addition to the transmission status of the terminal. For example, the information sent by the access network device to the first module for model inference may include at least one of the following: the amount of downlink data of the terminal over a period of time, the QoS corresponding to the service data of the terminal, or the downlink data transmission status of the terminal. For example, the success rate of the downlink data transmission of the terminal, or the failure rate of the downlink data transmission of the terminal, etc.

[0132] It is understandable that the access network device acts as the receiving end of uplink data. When determining requirements based on the terminal's transmission status, the access network device may consider not only the transmission status of the downlink data indicated by the access network device, but also the reception status of the uplink data by the access network device. For example, the packet loss of the uplink data, or the amount of uplink data received within a period of time. In other words, in this example: the terminal's transmission status includes not only the transmission status of the downlink data indicated by the core network device above, but also the reception status of the uplink data by the access network device.

[0133] Optionally, the process shown in Figure 2 further includes: the terminal or access network device determining a first configuration and / or a second configuration. The first configuration is used for the terminal to communicate with the access network device in the second mode, and the second configuration is used for the terminal to communicate with the access network device in the third mode. "Determining" the first configuration and / or the second configuration can be replaced with "obtaining" the first configuration and / or the second configuration.

[0134] In one possible implementation, a terminal or access network device may determine a first configuration, which is used for the second mode. It will be appreciated that the second mode corresponds to one or more configurations. In one design, the terminal may determine the first configuration from one or more configurations in the second mode. This process can be described as the terminal activating the first configuration. The terminal sends first indication information to the access network device, and the access network device receives the first indication information from the terminal. Alternatively, in one design, the access network device may determine the first configuration from one or more configurations in the second mode. This process can be described as the access network device activating the first configuration. The access network device sends second indication information to the terminal, and the terminal receives the second indication information from the access network device. The second indication information indicates the first configuration. Alternatively, in one design, the access network device may generate a new configuration, referred to as the first configuration. The access network device sends first configuration information to the terminal, and the terminal receives the first configuration information from the access network device. The first configuration information is used to configure the first configuration. The terminal determines the first configuration based on the first configuration information. In the second mode, the terminal and the access network device communicate based on the first configuration.

[0135] Optionally, one or more configurations corresponding to the second mode may be predefined, or configured by the access network device for the terminal. For example, for the second mode, the access network device configures multiple configurations for the terminal and assigns a corresponding identifier to each configuration. The default state of the multiple configurations configured by the access network device may be a deactivated state. Take the activation of a configuration by the access network device as an example: as described above, the access network device may send a second indication message to the terminal, and the second indication message carries the identifier of the activated configuration. When the terminal receives the second indication message, it obtains the identifier of the configuration carried by the second indication message and activates the corresponding configuration. It can be understood that in the second mode, the access network device and the terminal may communicate using the activated first configuration.

[0136] It is understood that the terminal may request the access network device to configure one or more configurations for its second mode. For example, before or during the terminal's switching to the second mode, the terminal may send a request to the access network device requesting the access network device to configure one or more configurations for the terminal's second mode. Alternatively, the access network device may proactively configure one or more configurations for the terminal's second mode. For example, when the access network device triggers the terminal to switch to the second mode, the access network device may configure multiple configurations corresponding to the second mode for the terminal.

[0137] In one possible implementation, the first configuration includes at least one of the following: a first sub-configuration, a second sub-configuration, or a third sub-configuration;

[0138] 1. The first sub-configuration is used to configure the first signal. For example, the first sub-configuration includes the period of the first signal and the frequency domain resources of the first signal. For example, the starting frequency domain position of the first signal, etc. The first signal is used by the terminal in the second mode to perform at least one of the following: mobility management, dynamic transmission resource indication, or mode switching.

[0139] Taking the example of a first signal used for dynamic transmission resource indication: the first signal includes a downlink signal and / or an uplink signal, the downlink signal is used to indicate uplink transmission resources and / or downlink transmission resources, and the uplink signal is used to request uplink transmission resources and / or downlink transmission resources. Optionally, the first signal can be a low-power signal, the downlink signal can be a low-power downlink signal (LPDS), and the uplink signal can be a low-power uplink signal (LPUS). For example, the access network device sends an LPDS to the terminal, the LPDS including uplink transmission resources and / or downlink transmission resources. The terminal communicates with the access network device using the indicated uplink transmission resources and / or downlink transmission resources. Alternatively, the terminal sends an LPUS to the access network device, the LPUS being used to request uplink transmission resources and / or downlink transmission resources from the access network device. Upon receiving the LPUS, the access network device allocates uplink transmission resources and / or downlink transmission resources to the terminal based on the terminal's request. Further, the access network device sends an LPDS to the terminal, the LPDS including the uplink transmission resources and / or downlink transmission resources allocated by the access network device to the terminal.

[0140] Optionally, the first signal, such as LPDS and LPUS, may be scrambled using an identifier of the terminal, such as using an RNTI of the terminal, so as to avoid conflicts between first signals of different terminals.

[0141] 2. The second sub-configuration is used to configure the radio bearer. The second sub-configuration includes at least one of the following: a predefined configuration, a general configuration, or a dedicated configuration.

[0142] In one possible implementation, multiple radio bearer configurations may be predefined. The second sub-configuration may include a default radio bearer configuration. The default radio bearer configuration may refer to a radio bearer configuration that is applied by default in the predefined multiple radio bearer configurations. A common configuration refers to a radio bearer configuration that is common to multiple terminals. For example, an access network device may configure a common / shared radio bearer configuration for multiple terminals through a system message. A dedicated configuration refers to a radio bearer configuration that is only applied to the current terminal. For example, the access network device may configure a radio bearer configuration for the terminal that is only used for the current terminal. For example, when the terminal is in the first mode, the access network device may configure a dedicated radio bearer configuration for the terminal. Alternatively, when the terminal last exits the third mode, the access network device configures a dedicated radio bearer configuration for the terminal.

[0143] In one possible implementation, SRB0 messages can use a dedicated configuration, meaning that the terminal and access network equipment can use the radio bearer corresponding to the dedicated configuration to transmit SRB0 messages. SRB1 and SBR2 messages can use a default configuration, meaning that the terminal and access network equipment can use the radio bearer corresponding to the default configuration to transmit SBR1 and SRB2 messages. Data radio bearer (DRB) messages can use either a universal or dedicated configuration, meaning that the terminal and access network equipment can use the radio bearer corresponding to either the universal or dedicated configuration to transmit DRB messages.

[0144] 3. The third sub-configuration is used to configure periodic transmission resources. The third sub-configuration is a predefined configuration, a general configuration, or a dedicated transmission resource configuration.

[0145] For example, the periodic transmission resources configured by the third sub-configuration may be referred to as configured grant (CG) resources. For example, when the terminal is in the first mode, or when the terminal last exits the third mode, the access network device may configure CG resources for the terminal.

[0146] Optionally, the first configuration further includes a fourth sub-configuration.

[0147] 4. The fourth sub-configuration is for mobility management. For example, depending on the capabilities of the access network equipment, mobility management can be performed based on terminal measurement reports (UE-centric), or based on the perception of the access network equipment (NW-centric).

[0148] In one possible implementation, the terminal or access network device may determine a second configuration, which is used for the third mode. It will be understood that the third mode corresponds to one or more configurations. In one design, the terminal may determine the second configuration within one or more configurations of the third mode. This process may be described as the terminal activating the second configuration. The terminal sends indication information to the access network device (for example, this indication information may continue to be referred to as first indication information, or other indication information, without limitation), and the access network device receives the indication information from the terminal. Alternatively, in one design, the access network device may determine the second configuration within one or more configurations of the third mode. This process may be described as the access network device activating the second configuration. The access network device sends indication information to the terminal (for example, this indication information may continue to be referred to as second indication information, or other indication information, without limitation), and the terminal receives the indication information from the access network device, which indicates the second configuration. The terminal activates the corresponding configuration based on the indication information. Alternatively, in one design, the access network device may generate a new configuration, which is referred to as the second configuration. The access network device sends configuration information (e.g., the configuration information may continue to be referred to as first configuration information, or other configuration information) to the terminal. The terminal receives the configuration information from the access network device and determines a second configuration based on the configuration information. In a third mode, the terminal and the access network device communicate based on the second configuration.

[0149] Optionally, one or more configurations corresponding to the third mode may be predefined or configured by the access network device for the terminal. For example, for the third mode, the access network device configures multiple configurations for the terminal and assigns a corresponding identifier to each configuration. The default state of the multiple configurations configured by the access network device may be a deactivated state. Take the activation of a configuration by the access network device as an example: as described above, the access network device may send an indication message to the terminal, and the indication message carries the identifier of the activated configuration. When the terminal receives the indication message, it obtains the identifier of the configuration carried in the indication message and activates the corresponding configuration. It can be understood that in the third mode, the activated second configuration is used for communication between the terminal and the access network device.

[0150] It is understood that the terminal may request the access network device to configure one or more configurations for its third mode. For example, before or during the terminal's switching to the third mode, the terminal may send a request to the access network device requesting the access network device to configure one or more configurations for the terminal's third mode. Alternatively, the access network device may proactively configure one or more configurations for the terminal's third mode. For example, when the access network device triggers the terminal to switch to the third mode, the access network device may configure multiple configurations corresponding to the third mode for the terminal.

[0151] Optionally, the second configuration includes a dedicated configuration. For example, the dedicated configuration refers to a configuration that applies only to the current terminal. For example, the access network device may determine the second configuration based on the QoS requirements of the terminal. The second configuration includes at least one of the following:

[0152] 1. Radio bearer configuration, for example, the access network device configures radio bearers corresponding to SRB1, SRB2, and DRB for the terminal. Optionally, the radio bearer includes packet data convergence protocol (PDCP) layer configuration and associated radio link control (RLC) layer bearer configuration.

[0153] 2. Measurement configuration, for example, the measurement configuration is used by the terminal to perform mobility management measurement and reporting.

[0154] 3. Or transmission resource configuration, for example, transmission resource configuration includes CG transmission resources, etc.

[0155] Through the above design, this embodiment designs different modes for the terminal according to the different stages and transmission requirements of the terminal. For example, when the terminal's data transmission requirements are not large, such as low performance requirements, or a small amount of data transmission, the terminal switches to the second mode. In the second mode, the terminal applies pre-configured periodic resources or obtains transmission resources based on low-power signals, and performs uplink and downlink data transmission, thereby achieving terminal energy saving while transmitting data. When the terminal's data transmission requirements increase, the terminal can enter the third mode based on the configuration of the access network device to improve data transmission performance. Through the design of the above configuration mode, the terminal can avoid the overhead caused by RRC state switching, and at the same time can save energy according to data transmission requirements.

[0156] For terminal triggered switching, the embodiments of the present application provide the processes of Figures 4 to 6, which can be used as possible implementation methods of terminal triggered switching.

[0157] As shown in FIG4 , a flow chart is provided, including:

[0158] Step 400: The terminal sends fourth indication information to the access network device, and the access network device receives the fourth indication information from the terminal.

[0159] The fourth indication information is used to indicate switching to the second mode or the third mode. In one possible implementation, the fourth indication information can be represented by one bit. For example, when the data corresponding to the one bit is "1," it indicates switching to the second mode. Alternatively, when the data corresponding to the one bit is "0," it indicates switching to the third mode. Alternatively, the reverse is also possible, without limitation.

[0160] In one possible implementation, the fourth indication information may be carried in an LPUS message or an RRC message. For example, the terminal may send an LPUS message to the access network device on the configured LPUS resources, and the LPUS message carries the fourth indication information. Alternatively, the terminal may send an RRC message to the access network device on the pre-configured CG resources, and the RRC message carries the fourth indication information. Alternatively, the terminal may send an LPUS signal to the access network device on the configured LPUS resources, and the LPUS signal is used to request uplink transmission resources. Based on the request of the terminal, the access network device sends an LPDS signal to the terminal, and the LPDS signal includes the uplink transmission resources allocated by the access network device to the terminal. The terminal sends an RRC message to the access network device on the uplink transmission resources allocated by the access network device, and the RRC message carries the fourth indication information.

[0161] Optionally, step 410: the terminal sends information about the terminal to the access network device, and the access network device receives the information from the terminal.

[0162] For example, the terminal reports terminal information to the access network device, which is used by the access network device to determine the first configuration and / or the second configuration. For example, the terminal information reported by the terminal includes at least one of the following: the terminal's transmission status, the requirements determined by the terminal (such as the first requirement or the second requirement determined by the terminal), or the analysis results corresponding to the AI. For example, the analysis results corresponding to the AI ​​include: the terminal's corresponding appropriate configuration in the second mode or the third mode, etc.

[0163] In a possible implementation, the information of step 400 and step 410 may be carried in one message and reported to the access network device, or carried in different messages and reported to the access network device separately, without limitation.

[0164] Step 420: The access network device sends first indication information or first configuration information to the terminal, and the terminal receives the first indication information or first configuration information from the access network device.

[0165] For example, upon receiving the fourth indication information, the access network device may determine whether the terminal switches to the second mode or the third mode based on the indication of the fourth indication information. In the scenario where the terminal switches to the second mode, the access network device may determine whether the current configuration of the second mode matches the current situation of the terminal. For example, the access network device may determine whether the current configuration of the second mode matches the current situation of the terminal based on the terminal information reported by the terminal in step 410. If a matching configuration exists, the access network device sends first indication information to the terminal, which carries an identifier of the matching configuration. In the above description, the configuration that matches the second mode is referred to as the first configuration. In the scenario where the terminal switches to the third mode, the access network device may determine whether the current configuration of the third mode matches the current situation of the terminal. For example, the access network device may determine whether the configuration of the third mode matches the current situation of the terminal based on the terminal information reported by the terminal in step 410. If a matching configuration exists, the access network device sends first indication information to the terminal, which carries an identifier of the matching configuration. In the above description, the matching configuration corresponding to the third mode is referred to as the second configuration. Optionally, the first indication information can be carried in an LPDS message or an RRC message. Further, the access network device can send an LPDS message or an RRC message to the terminal on a pre-configured CG resource or a dedicated resource. Or,

[0166] In the scenario where the terminal switches to the second mode or the third mode, there is no configuration that matches the current configuration. The access network device can generate a new configuration. For example, the access network device can generate a new configuration based on the terminal information reported by the terminal in step 410. The access network device can send a first configuration information to the terminal, and the first configuration is used to configure a new configuration for the terminal. For example, if the terminal has pre-configured CG resources, the access network device can send an RRC message to the terminal on the pre-configured CG resources, and the RRC message carries the first configuration information. Alternatively, if there are no pre-configured CG resources on the terminal side, or the access network device does not use the pre-configured CG resources to carry the first configuration information, the access network device can send an LPDS to the terminal, and the LPDS is used to indicate the downlink transmission resources. The access network device sends an RRC message to the terminal on the downlink transmission resources indicated by the LPDS, and the RRC message carries the first configuration.

[0167] As shown in Figure 5, the embodiment of the present application also provides a flow chart, which differs from Figure 4 in that although the terminal triggers the mode switch, the base station decides the final terminal's switch. As shown in Figure 5, it includes:

[0168] Step 500: The terminal reports its information to the access network device, and the access network device receives the information from the terminal.

[0169] Regarding this process, please refer to the description in step 410 and will not be described in detail. Step 500 is optional and may or may not be performed. There is no limitation on this.

[0170] Step 510: The terminal sends a handover request to the access network device, and the access network device receives the handover request from the terminal.

[0171] For example, the handover request includes the fourth indication information, and the handover request is used to request the terminal to switch to the second mode or the third mode. Upon receiving the handover request, the access network device sends a handover response to the terminal, as shown in step 520. Optionally, the handover request can be carried in an LPUS message or an RRC message.

[0172] Step 520: The access network device sends a handover response to the terminal, and the terminal receives the handover response from the access network device.

[0173] For example, the handover response may indicate that the access network device approves the terminal's handover request, or the handover response may indicate that the access network device disapproves or rejects the terminal's handover request, without limitation. The implementation process for whether the access network device approves the terminal's handover request is not limited. For example, in one possible implementation, the access network device may determine whether to approve the terminal's handover request based on the terminal information reported by the terminal in step 500. Optionally, the handover response may be carried in an LPDS message or an RRC message.

[0174] It is understandable that when the switching response indicates that the access network device agrees to the switching, the terminal switches to the second mode or the third mode. Alternatively, when the switching response indicates that the access network device does not agree to the switching, the terminal no longer performs mode switching.

[0175] In one possible implementation, the second mode or the third mode may each correspond to multiple configurations. For example, in step 510, when the terminal requests to switch to the second mode or the third mode, the terminal may determine to activate a configuration corresponding to the second mode or the third mode, and the switching request sent to the access network device in step 510 may include an identifier of the activated configuration. Upon receiving the terminal's switching request, the access network device may perform two determinations: whether to approve the terminal's switching request; and whether to approve the terminal's activated configuration. If both are approved, the access network device sends a response to the terminal approving the switching. If either is not approved, the access network device sends a response to the terminal rejecting the switching. Furthermore, the access network device may include a reason for rejecting the switching in the switching response. For example, the reason may include rejection of the terminal's switching request or rejection of the terminal's activated configuration. Alternatively, the second mode or the third mode may each correspond to a single configuration. In this case, the identifier of the activated configuration may not be included in step 510. When the terminal switches to the second mode or the third mode, it must communicate with the access network device using the configuration corresponding to the second mode or the third mode.

[0176] As shown in Figure 6, the embodiment of the present application also provides a flow chart, which differs from Figure 5 in that: the terminal initiates a mode switching request, but the access network device determines the final configuration. As shown in Figure 6, it includes:

[0177] Step 600: The terminal sends information about the terminal to the access network device, and the access network device receives the information from the terminal.

[0178] This step 600 is optional.

[0179] Step 610: The terminal sends a handover request to the access network device, and the access network device receives the handover request from the terminal.

[0180] For example, the handover request includes the fourth indication information, and the terminal may request to switch to the second mode or the third mode. Optionally, the handover request may be carried in an LPUS message or an RRC message.

[0181] Step 620: The access network device sends first indication information or first configuration information to the terminal, and the terminal receives the first indication information or first configuration information from the access network device.

[0182] For example, the access network device may determine whether there is a suitable or matching configuration in the second mode or the third mode to which the terminal requests to switch. If so, the access network device sends a first indication message to the terminal, and the first indication message is used to indicate a configuration in the second mode or the third mode. The first indication message may carry an identifier for activating the configuration in the second mode or the third mode. Alternatively, if there is no suitable or matching configuration in the second mode or the third mode, the access network device may generate a new configuration and send a first configuration message to the terminal, and the first configuration message is used to configure the new configuration. Optionally, the first indication message may be carried in an LPDS message or an RRC message. The first configuration information may be carried in an RRC message.

[0183] Step 630: The terminal sends a mode switching confirmation to the access network device, and the access network device receives the mode switching confirmation from the terminal.

[0184] For example, upon receiving the first indication information or the first configuration information in step 620, the terminal may send a mode switching confirmation to the access network device. Optionally, the mode switching confirmation may be carried in an LPUS message or an RRC message. Step 630 is optional. In the process of FIG. 6 , step 630 may be performed or may not be performed, without limitation.

[0185] For access network device triggering switching, an embodiment of the present application provides the process shown in Figure 7. The process of Figure 7 can be used as a possible implementation method for access network device triggering switching.

[0186] As shown in FIG7 , the embodiment of the present application further provides a flow chart, including:

[0187] Step 700: The access network device sends a mode switching instruction to the terminal, and the terminal receives the mode switching instruction from the access network device.

[0188] For example, the mode switching indication includes fifth indication information, which is used to instruct the terminal to switch to the second mode or the third mode. In one possible implementation, the access network device can generate a configuration corresponding to the second mode or the third mode to which the terminal switches, and carry the corresponding configuration in the mode switching indication. For example, the mode switching indication carries first configuration information, and the first configuration information is used to configure the newly generated configuration of the access network device for the second mode or the third mode to which the terminal switches. Alternatively, in another possible implementation, the access device can pre-configure multiple configurations for the second mode or the third mode of the terminal. The terminal can select or activate a configuration from multiple configurations. The mode switching indication in step 700 carries an identifier of the selected or activated configuration. Optionally, the mode switching indication can be carried in an RRC message or an LPDS message. It can be understood that if the second mode or the third mode corresponds to a configuration, the mode switching indication can only carry the fifth indication information and no longer carry the identifier of the activated configuration.

[0189] Step 710: The terminal switches to the second mode or the third mode according to the instruction of the fifth instruction information.

[0190] Step 720: The terminal sends a mode switching confirmation to the access network device, and the access network device receives the mode switching confirmation from the terminal.

[0191] Optionally, the mode switching confirmation may be carried in an RRC message or an LPUS message. Step 720 is optional. In the process of FIG7 , step 720 may be performed, or may not be performed. There is no limitation thereto.

[0192] Optionally, in an embodiment of the present application, the terminal may support an RRC state, also known as a single RRC state. In an RRC state, the terminal supports multiple modes. For example, in an RRC state, the terminal supports a first mode, a second mode, and a third mode. Since the terminal does not switch the RRC state during mode switching, the delay and overhead of the terminal RRC switching can be reduced.

[0193] With this design, after completing the initial access process, the terminal can switch between the second and third modes based on the switching conditions and the switching process. The switching conditions ensure that the terminal and the access network equipment can monitor the terminal's current service data transmission requirements in real time, while the switching process enables rapid mode switching based on different service data transmission requirements, allowing the terminal to flexibly meet service transmission needs while achieving energy conservation.

[0194] Example 2

[0195] In the foregoing description, the access network device can configure at least one configuration for the second mode / third mode of the terminal. Alternatively, when there is no suitable or matching configuration in the currently configured configuration of the access network device, the access network device can generate a new configuration and configure the new configuration to the terminal through the first configuration information. Optionally, the access network device can adopt a separated architecture. For example, the access network device includes a first unit and a second unit. In the embodiment of the present application, the names of the first unit and the second unit are not limited. For example, the first unit can be called a CU and the second unit can be called a DU. In the following description, the CU and the DU are used as examples for explanation. When the access network device adopts a CU-DU separated architecture, the process of the access network device generating a configuration includes: the CU generates a third configuration, the third configuration is the configuration corresponding to the CU, for example, the third configuration may include the PDCP configuration of the radio bearer; the DU generates a fourth configuration and sends the fourth configuration to the CU, the fourth configuration is the configuration corresponding to the DU, for example, the fourth configuration may include the RLC configuration of the radio bearer; the CU generates a configuration based on the third configuration and the fourth configuration. For example, the one configuration may be the first configuration or the second configuration described above, or may be another configuration other than the first configuration or the second configuration, without limitation.

[0196] Optionally, in an embodiment of the present application, the access network device may adopt a CU-DU separation architecture. It can be understood that CU and DU can be understood as a division of the access network device from a logical functional perspective. The CU and DU can be physically separated or deployed together without restriction. Multiple DUs can be connected to (share) one CU, and one DU can also be connected to multiple CUs. Multiple CUs can be physically set up centrally or separately. The CU and DU can be connected through an interface, for example, the interface can be an F1 interface. The CU and DU can be divided according to the protocol layer of the wireless network: for example, the PDCP and the protocol layers above the PDCP layer are set in the CU, for example, the CU is used to perform the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer and the PDCP layer. The protocol layers below the PDCP layer are set in the DU. For example, the DU is used to perform the functions of the RLC layer, the media access control (MAC) layer and the physical layer.

[0197] The above division of the processing functions of CU and DU according to the protocol layer is only an example, and they can also be divided in other ways. For example, the CU or DU can be divided into functions with more protocol layers, and for another example, the CU or DU can be divided into partial processing functions with the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. Alternatively, the functions of the CU or DU can be divided according to the service type or other system requirements, for example, by delay, the functions whose processing time needs to meet the delay requirements are set in the DU, and the functions that do not need to meet the delay requirements are set in the CU, etc. Alternatively, the CU can have one or more functions of the core network. For example, the CU can be set on the network side to facilitate centralized management. The DU can have multiple radio frequency functions, for example, the radio frequency function of the DU is set remotely.

[0198] Furthermore, the CU can be split into the CU-CP and the CU-UP. For example, the CU's functions can be further split. For example, the control plane (CP) and the user plane (UP) can be separated into the CU control plane (CU-CP) and the CU user plane (CU-UP), respectively. Optionally, the CU-CP and CU-UP are implemented by different entities and connected via the E1 interface. The CU-CP and CU-UP can be coupled with the DU to jointly perform the functions of the access network device. The interface between the CU-CP and the DU can be F1-C, and the interface between the CU-UP and the DU can be F1-D.

[0199] In one possible implementation, the access network device may generate at least one configuration corresponding to the second mode, and the access network device may configure the at least one configuration to the terminal. The access network device may generate at least one configuration corresponding to the third mode, and the access network device may configure the at least one configuration to the terminal. When the access network device determines that the terminal needs to switch modes, the access network device may send fifth indication information to the terminal, where the fifth indication information is used to instruct the terminal to switch to the second mode or the third mode. In the scenario of instructing the terminal to switch to the second mode, the access network device may activate a configuration in the at least one configuration corresponding to the second mode, which is referred to as the first configuration above, and send indication information (e.g., the first indication information) to the terminal to instruct the activation of the first configuration. The terminal and the access network device communicate in the second mode using the first configuration. Alternatively, in the scenario of instructing the terminal to switch to the third mode, the access network device may activate a configuration in the at least one configuration corresponding to the third mode, which is referred to as the second configuration above, and send indication information to the terminal to activate the second configuration. The terminal and the access network device communicate in the third mode using the second configuration.

[0200] Taking the access network device adopting the CU-DU separation architecture as an example, as shown in FIG8 , the embodiment of the present application provides a flow diagram including:

[0201] Step 800: The CU generates a third configuration.

[0202] For example, the CU may determine the air interface resource configuration of the terminal based on the air interface transmission status of the terminal. That is, the third configuration may be the air interface resource configuration. For example, the CU may determine the air interface resource configuration of the terminal based on the change in data transmission of the terminal, or based on the prediction of the AI ​​module. Optionally, the air interface resource configuration of the terminal includes the radio bearer configuration of the terminal.

[0203] Step 810: The CU sends indication information to the DU, and the DU receives the indication information from the CU, where the indication information is used to instruct the DU to provide the fourth configuration.

[0204] Step 820: The DU sends the fourth configuration to the CU, and the CU receives the fourth configuration from the DU.

[0205] It is understood that the third configuration and the fourth configuration have a one-to-one correspondence. The indication information in step 810 may include the requirements that the radio bearer configuration in the third configuration needs to meet, such as QoS requirements. Optionally, the indication information in step 810 may also include an identifier corresponding to the third configuration. Alternatively, the CU may not indicate the identifier of the third configuration to the DU, and the CU may identify the corresponding configuration through sequential configuration.

[0206] Step 830: The CU generates at least one configuration according to the third configuration and the fourth configuration.

[0207] Optionally, the third configuration may be referred to as a high-layer configuration, for example, the third configuration may be a configuration corresponding to the PDCP layer and protocol layers above the PDCP layer. The fourth configuration may be referred to as a low-layer configuration, for example, the fourth configuration may be a configuration corresponding to protocol layers below the PDCP layer.

[0208] Step 840: The CU sends configuration information to the terminal through the DU, and the terminal receives the configuration information from the CU through the DU. The configuration information is used to configure at least one configuration to the terminal.

[0209] It is understandable that the at least one configuration includes at least one configuration corresponding to the second mode and / or at least one configuration corresponding to the third mode. That is, in an embodiment of the present application, the CU may generate at least one configuration corresponding to the second mode, and configure the at least one configuration corresponding to the second mode to the terminal through step 840. And / or, the CU may generate at least one configuration corresponding to the third mode, and configure the at least one configuration corresponding to the third mode to the terminal through step 840.

[0210] In step 840, the DU may transparently transmit the configuration information.

[0211] Optionally, step 850: the CU determines whether the terminal switches to the second mode or the third mode.

[0212] For example, if the CU determines that the terminal switches to the second mode, the CU may select or activate a configuration from at least one configuration corresponding to the second mode, and indicate the selected or activated configuration to the terminal in step 860. Alternatively, if the CU determines that the terminal switches to the third mode, the CU may select or activate a configuration from at least one configuration corresponding to the third mode, and indicate the selected or activated configuration to the terminal in step 860.

[0213] Optionally, step 860: the CU sends indication information to the terminal, and the terminal receives the indication information from the CU, where the indication information is used to indicate activation of a configuration.

[0214] For example, the CU may send an indication message to the DU, and the DU may transparently transmit the indication message and forward the indication message to the terminal. The indication message carries the identifier of the activated configuration, such as the serial number of the activated configuration. Optionally, the indication message may be carried in an RRC message. Alternatively, the CU sends an indication message to the DU, and the indication message carries the identifier of the activated configuration. Upon receiving the indication message, the DU instructs the terminal to activate the corresponding configuration. Optionally, the indication message may be carried in an LPDS message.

[0215] In another possible implementation, the concepts of "second mode" and "third mode" can be eliminated. For example, the access network device can generate at least one configuration and configure it for the terminal. When the access network device determines that a configuration switch is necessary, it can activate one of the at least one configuration, and the terminal and the access network device can communicate using the activated configuration. For example, the access network device can generate five configurations and configure them for the terminal. It will be understood that, by default, these five configurations are deactivated. When the access network device determines to switch from one configuration to another, it can send a switch indication to the terminal, which includes an identifier for the other configuration. Upon receiving the switch indication, the terminal switches from the current configuration to the other configuration, and the terminal and the access network device can communicate using the other configuration. It will be understood that when this possible implementation is applied to an architecture with a separate CU and DU for the access network device, it differs from the process in FIG. 8 above. In step 850, "the CU determines that the terminal switches to the second mode or the third mode" can be replaced with "the CU determines that the terminal switches from one configuration to another."

[0216] Through the above design, when the access network device adopts the CU-DU separation architecture, the CU and DU in the access network device can interact with each other, and the solution of the embodiment of the present application can be implemented under the open RAN architecture.

[0217] [Example 3]

[0218] As shown in Figure 9, the access network equipment includes a near-real-time access network intelligent controller (RIC) module for model training and inference. For example, the near-real-time RIC can be used to train an AI model and use the AI ​​model for inference. For example, the near-real-time RIC can obtain network-side and / or terminal-side information from at least one of the CU, DU, or RU, and this information can be used as training data or inference data.

[0219] Optionally, a non-real-time RIC is included outside the access network device. For example, the non-real-time RIC can be located in operations, administration and maintenance (OAM), cloud servers, core network devices, or other network devices. Non-real-time RIC is used for model training and reasoning. For example, non-real-time RIC is used to train an AI model and use the model for reasoning. For example, non-real-time RIC can obtain information on the network side and / or the terminal side from at least one of the CU, DU or RU. The information can be used as training data or reasoning data, and the reasoning result can be submitted to at least one of the CU, DU, RU or terminal.

[0220] As shown in FIG10 , the embodiment of the present application provides a flow chart, including:

[0221] Step 1000: The terminal sends the transmission status of the terminal to the RIC, and the RIC receives the transmission status of the terminal from the terminal.

[0222] For example, the terminal may send the terminal's transmission status to the RIC through transparent transmission of the CU and DU. Optionally, the RIC may be a near real-time RIC or a non-real-time RIC, etc., without limitation.

[0223] In one possible implementation, the terminal's transmission status sent to the RIC by the terminal includes at least one of the following: the terminal's transmitted data volume, the terminal's data type, the QoS of the terminal's data, the terminal's current configuration, or the terminal's packet loss. Upon receiving the terminal's transmission status, the RIC may input the terminal's transmission status into an AI model, with the AI ​​model's output including an AI analysis result. For example, the AI ​​analysis result may include requirements, recommended terminal configurations, or a switching indication. For example, the requirement may be the requirement described above. If the requirement is the first requirement, the terminal may switch to the second mode based on the first requirement. Alternatively, if the requirement is the second requirement, the terminal may switch to the third mode based on the second requirement. Alternatively, the output of the AI ​​model may be a switching indication. For example, the switching indication may indicate switching to the second mode or the third mode. In scenarios where the terminal triggers a switching, the terminal may switch to the second mode or the third mode based on the switching indication output by the AI ​​model. In scenarios where an access network device triggers a switching, the access network device may send fifth indication information to the terminal based on the switching indication output by the AI ​​model. The fifth indication information is used to instruct the terminal to switch to the second mode or the third mode. For example, the recommended terminal configuration may be a configuration that is suitable or matches the terminal situation in the aforementioned activation configuration scenario.

[0224] Step 1010: The RIC sends the AI ​​analysis result to the terminal, and the terminal receives the AI ​​analysis result from the RIC.

[0225] For example, RIC can transparently transmit AI analysis results to the terminal through CU and DU.

[0226] Step 1020: The terminal switches to the second mode or the third mode according to the AI ​​analysis result.

[0227] For example, the AI ​​analysis result includes a requirement. When the requirement is the first requirement, the terminal switches to the second mode. Or when the requirement is the second requirement, the terminal switches to the third mode. Alternatively, if the AI ​​analysis result includes a switching instruction, the terminal switches to the second mode or the third mode according to the switching instruction. Of course, the AI ​​analysis result may also include other information, such as a recommended terminal configuration. In the process of Figure 10, the process of terminal switching mode is mainly described, and other processes are not repeated.

[0228] Through the above design, when the access network equipment adopts the CU-DU separation architecture, the terminal and RIC can interact, and the terminal can use the AI ​​analysis results output by the RIC to switch to the second mode or the third mode.

[0229] As shown in Figure 11, the embodiment of the present application also provides a flow chart, which differs from Figure 10 in that the RIC sends the AI ​​analysis results to the CU in the access network device, and the CU triggers the terminal to switch modes based on the AI ​​analysis results. As shown in Figure 11, it includes:

[0230] Step 1100: The CU sends the transmission status of the terminal to the RIC, and the RIC receives the transmission status of the terminal from the terminal.

[0231] For example, the CU can obtain the terminal's transmission status. For example, the terminal can report the terminal's transmission status to the CU, and the CU can obtain the terminal's transmission status based on the terminal's report. When the RIC receives the terminal's transmission status, it can input the terminal's transmission status into the AI ​​model, and the output of the AI ​​model includes the AI ​​analysis results.

[0232] Step 1110: The RIC sends the AI ​​analysis result to the CU, and the CU receives the AI ​​analysis result from the RIC.

[0233] In one possible implementation, in an architecture where the CU-CP and CU-UP are separated, in step 1100, the CU-UP may send the terminal's transmission status to the CU-CP. The CU-CP sends the terminal's transmission status to the RIC. In step 1110, the RIC indicates the AI ​​analysis result to the CU-CP. In step 1120, the CU-CP triggers the terminal to switch to the second mode or the third mode based on the AI ​​analysis result.

[0234] Step 1120: The CU triggers the terminal to switch to the second mode or the third mode based on the AI ​​analysis result.

[0235] For example, when the AI ​​analysis result includes a requirement. When the requirement includes the first requirement, the CU triggers the terminal to switch to the second mode. Alternatively, when the requirement includes the second requirement, the CU triggers the terminal to switch to the third mode. Alternatively, when the AI ​​analysis result includes a switching indication, the CU triggers the terminal to switch to the second mode or the third mode based on the switching indication.

[0236] Furthermore, the AI ​​analysis result may also include: the transmission requirements of the wireless bearer. The CU can determine whether there is a suitable configuration in the current configuration of the second mode or the third mode based on the transmission requirements of the wireless bearer fed back by the AI ​​analysis result. If there is a suitable configuration, the CU sends an indication message to the terminal through the DU, and the indication message is used to indicate the activation of the appropriate configuration. This process is mainly described in step 1130. If there is no suitable configuration, the CU can generate a corresponding configuration and request the DU to generate a corresponding underlying configuration. The CU generates a new configuration based on the corresponding configuration of the CU and the corresponding configuration of the DU, and configures the new configuration to the terminal.

[0237] Step 1130: The CU sends indication information to the terminal via the DU, and the terminal receives the indication information from the CU via the DU. The indication information is used to indicate activation of a configuration in the second mode or the third mode.

[0238] Through the above design, when the access network device adopts a CU-DU separation architecture, the CU and RIC in the access network device can interact, and the CU can use the AI ​​analysis results output by the RIC to trigger the terminal to switch to the second mode or the third mode.
