[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[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 December 21, 2023, with application number 202311778550.1 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0004] To improve the battery life of terminal devices, terminal devices can extend their battery life by adopting larger-capacity batteries, low-power, high-performance components, or displays with power-saving technology. On the network side, while ensuring effective data transmission, the Third Generation Partnership Project (3GPP) has defined a variety of energy-saving communication technologies to reduce unnecessary power consumption in terminal devices, thereby achieving energy conservation. One energy-saving communication technology is the single radio resource control state (single RRC state). The single RRC state includes an RRC state with two operating modes: default mode and enhanced mode. Enhanced mode is suitable for data transmission with large amounts of data, while default mode is suitable for data transmission with small amounts of data. Compared to enhanced mode, terminal devices in default mode can use fewer antennas, narrower bandwidth, and fewer links, resulting in lower energy consumption.

[0005] To enable single RRC state, a terminal device acquires two sets of configuration information after initial access: one for communication in default mode and one for communication in enhanced mode. Accordingly, the network device must store the terminal device's configuration information for each mode. However, network devices have limited memory. If the network device stores too much information, the maximum number of users that can be supported by the cell will be limited, thereby affecting the network device's communication performance. Summary of the Invention

For example, in the embodiments of this application, "first information" and "second information" are used to distinguish two pieces of information and do not define the priority or importance of the two pieces of information.

[0110] The embodiments of the present application will be presented around a system including multiple devices, components, modules, etc. It should be understood that the system may include other devices, components, modules, etc. not mentioned, or may only include some of the devices, components, or modules, etc. mentioned in the embodiments.

[0111] The following first introduces a communication system to which the embodiments of the present application are applicable.

[0112] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example, universal mobile telecommunications system (UMTS), wireless local area network (WLAN), short-range wireless communication systems (such as sidelink, wireless fidelity (Wi-Fi), Bluetooth, etc.), wired networks, vehicle-to-everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems (such as long term evolution (LTE) systems), LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, fifth generation (5G) mobile communication systems (such as new radio (NR) systems), future communication systems (such as sixth generation (6G) systems), and the like. The present invention relates to a mobile communication system (generation, 6G) or other similar communication systems, without limitation. The embodiments of the present application are described using the communication system shown in FIG1 as an example. When the technical solutions of the embodiments of the present application are applied to other communication systems, the devices, components, modules, etc. in the embodiments can be replaced with corresponding devices, components, modules in other communication systems without limitation.

[0113] Figure 1 is a schematic diagram of the architecture of the communication system used in the embodiment of the present application. As shown in Figure 1, the communication system includes an access network 100 and a core network 200. Optionally, the communication system may also include the Internet 300. The access network 100 may include at least one radio access network (RAN) node, such as 110a and 110b in Figure 1, and may also include at least one terminal device, such as 120a-120j in Figure 1. 110a is a base station, 110b is a micro station, 120a, 120e, 120f and 120j are mobile phones, 120b is a car, 120c is a gas pump, 120d is a home access point (HAP) arranged indoors or outdoors, 120g is a laptop, 120h is a printer, and 120i is a drone. The same terminal device or network device can provide different functions in different application scenarios. For example, in FIG1 , there are mobile phones 120 a , 120 e , 120 f , and 120 j . Mobile phone 120 a can access base station 110 a , connect to car 120 b , communicate directly with mobile phone 120 e , and access HAP.

Mobile phone 120 j can control drone 120 i .

[0114] A network device is a network-side device with wireless transceiver functions, which can be an access network device or a core network device. For ease of understanding, the following description takes the network device as an access network device as an example. A network device can be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, and is called a RAN device or network device. A RAN can be an access network in the 3rd Generation Partnership Project (3GPP), such as a 4G, 5G, or future-oriented 6G network.

[0115] The RAN can also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above. RAN equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a 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.

[0116] The RAN device can also be a module or unit that performs some of the functions of the base station, for example, it can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU here performs the functions of the radio resource control protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the function of the service data adaptation protocol (SDAP); the DU performs the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For detailed descriptions of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be set separately, or they can be included in the same network element, such as the 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). In different systems, CU, DU or RU may 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, and RU may also be called O-RU. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The network device may be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the network device.

[0117] In the embodiments of the present application, the functions of the network device may be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device functions. The control subsystem that includes the network device functions may be a control center in the aforementioned application scenarios such as smart grid, industrial control, smart transportation, and smart city.

[0118] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as a terminal, terminal apparatus, user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal device may be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home appliance, etc. In the embodiments of the present application, a device for implementing the function of a terminal device may be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system or a combination of devices or components capable of implementing the function of the terminal device, which may be installed in the terminal device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0119] In the embodiment of the present application, the functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or may be performed by a device that includes the functions of the terminal device.

[0120] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0121] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.

[0122] In one embodiment, the embodiment of the present application can be applied to a standalone (SA) scenario or a non-standalone (NSA) scenario. Figure 2a shows a schematic diagram of an SA communication system, in which a terminal device is connected to a single access network device, and the access network device to which the terminal device is connected and the core network to which the access network device is connected are of the same standard. For example, the core network is a 5G Core, the access network device is a 5G access network device, and the 5G access network device is directly connected to the 5G Core. For another example, the core network is a 6G Core, the access network device is a 6G access network device, and the 6G access network device is directly connected to the 6G Core.

[0123] In another embodiment, the embodiments of the present application can also be applied to a dual connectivity (DC) scenario. Figure 2b shows a schematic diagram of a DC communication system, in which the terminal device is simultaneously connected to access network devices of different / same standards. For example, the core network is 5G Core, and the terminal device is simultaneously connected to the 5G access network device and the 6G access network device, wherein the 5G access network device serves as the main station and the 6G access network device serves as the auxiliary station. For another example, the core network is 6G Core, and the terminal device is simultaneously connected to the 6G access network device and the 5G access network device, wherein the 6G access network device serves as the main station and the 5G access network device serves as the auxiliary station. For another example, the core network is 6G Core, and the terminal device is simultaneously connected to two 6G access network devices, that is, the main station and the auxiliary station are both 6G access network devices.

[0124] Next, the technical features involved in the embodiments of this application are introduced.

[0125] Compared with the LTE communication system, in order to enable the terminal device to recover to the radio resource control (RRC) connection state more quickly, the NR communication system, in addition to supporting the RRC idle state and the RRC connected state, also introduces the RRC inactive state. The access network device (for example, gNodeB) corresponding to the terminal device in the RRC inactive state maintains the context of the terminal device. In other words, the air interface state of the terminal device in the RRC inactive state is similar to the air interface state when it is in the RRC idle state. From the core network side, the terminal device in the RRC inactive state is still in the connection management (CM) state.

[0126] If the terminal device is in an inactive state, the terminal device needs to maintain the context of the inactive state. The context may include, but is not limited to: air interface configuration information, security-related information (for example, keys, or count values, etc.), QoS flow and data radio bearer (DRB) mapping, cell radio network temporary identifier (Cell-Radio network temporary identifier, C-RNTI), and original cell identity (identity, ID), etc. For specific content, please refer to the relevant "UE inactive AS context" in the 3GPP related protocols, which will not be repeated here. Correspondingly, the base station side also needs to maintain the context of the terminal device. The context may include, but is not limited to: terminal device capability information, terminal device air interface configuration information, terminal device security capability information, terminal device air interface security information, and protocol data unit (PDU) session resources, etc. For specific content, please refer to the relevant content in "UE Context Information-Retrieve UE Context Response" in the 3GPP related protocols, which will not be repeated here.

[0127] In order to reduce the energy consumption on the terminal device side, the probability of a single radio resource control state (single RRC state) is introduced. The core idea is: different from the three RRC states defined in the NR communication system, the single RRC state only contains one RRC state, and the RRC state has two working modes, namely the default mode and the enhanced mode. The enhanced mode is suitable for data transmission with large amounts of data, and the default mode is suitable for data transmission with small amounts of data. Compared with the enhanced mode, the terminal device under the default mode can use fewer antennas, narrower bandwidth, and fewer links or beam detections, etc., so the terminal device under the default mode will have lower energy consumption. In one embodiment, in addition to these two working modes, the RRC state may also have an initial mode. The terminal device in the initial mode has not established a connection with the network side, for example, the initial power-on user. For the terminal device in the initial mode, the terminal device needs to obtain the configuration information of the default mode and / or the configuration information of the enhanced mode. Optionally, after obtaining the configuration information of the default mode and the configuration information of the enhanced mode, the terminal device can enter the default mode or the enhanced mode as needed. For example, the terminal device can enter the default mode by default.

[0128] It is understood that for a terminal device in initial mode, the terminal device has not yet established a connection with the network side, so the terminal device needs to establish a connection with the network side. The terminal device can obtain context during the process of establishing a connection with the network side. Establishing a connection between the terminal device and the network side can be understood as: establishing a connection between the terminal device and the network device, and / or establishing a connection between the terminal device and the core network.

[0129] It should be noted that the default mode may also be referred to as the default state, without limitation. The enhanced mode may also be referred to as the enhanced state, without limitation. The initial mode may also be referred to as the initial state, without limitation.

[0130] To enable single RRC state, a terminal device acquires two sets of configuration information after initial access: one for communication in default mode and one for communication in enhanced mode. Accordingly, network devices must store the terminal device's configuration information for each mode. However, network devices have limited memory. Excessive storage limits the maximum number of users a cell can support, impacting network device communication performance. Therefore, reducing the amount of information stored in network devices and improving communication performance is a pressing technical challenge.

[0131] In view of this, an embodiment of the present application provides a communication method and device for reducing the storage information of a network device, which is conducive to improving the communication performance of the network device. The method can be applied to the communication system shown in Figure 1, Figure 2a, or Figure 2b, but is not limited thereto. For example, the network device can be the network device shown in Figure 1, Figure 2a, or Figure 2b, or a component in the network device, or other devices including the network device, etc., without limitation. For example, the first terminal device can be the terminal device shown in Figure 1, Figure 2a, or Figure 2b, or a component in the terminal device, or other devices including the terminal device, etc., without limitation.

[0132] Figure 3 exemplarily illustrates a flow chart of a first communication method provided by an embodiment of the present application. In this embodiment, a network device can configure a first operating mode and / or a second operating mode for multiple terminal devices by storing first information and second information for different QoS and / or different types of terminal devices, thereby reducing the amount of information stored by the network device. As shown in Figure 3 , the first communication method may include the following.

[0133] S301: A network device sends a first system message. For example, the network device may broadcast the first system message.

[0134] Accordingly, the first terminal device receives the first system message.

[0135] The first system message may be, for example, a system information block (SIB), but is not limited thereto. The first system message may carry the first information. The first information may be used for communication of one or more QoS (or one or more QoS lists), or the first information may be used for communication of one or more types of terminal devices, or the first information may be used for communication of one or more QoS and for communication of one or more types of terminal devices. For ease of understanding, the following description will be made using the example of the first information being used for communication of multiple QoS and / or multiple types of terminal devices. Alternatively, it may be stated as follows: the first information may be used for communication of different QoS (or different QoS lists), or the first information may be used for communication of different types of terminal devices, or the first information may be used for communication of different QoS and for communication of different types of terminal devices. Among them, communication of multiple QoS may be understood as communication of multiple QoS requirements, or as communication of services of multiple QoS requirements. Communication of different QoS may be understood as communication of different QoS requirements, or as communication of services of different QoS requirements. The multiple types of terminal devices may include at least two of the following: an enhanced mobile broadband (EMBB) terminal device, an ultra-reliable low latency communication (URRLC) terminal device, a reduced capability (RedCap) terminal device, or a massive machine type communications (MMTC) terminal device, etc., without limitation.

[0136] The first information may include the first configuration information of the first operating mode, or the first information may include the second configuration information of the second operating mode, or the first information may include the first configuration information of the first operating mode and the second configuration information of the second operating mode. FIG3 illustrates an example in which the first information is used for communications of multiple QoSs, and the first information includes the first configuration information of the first operating mode and the second configuration information of the second operating mode. The first configuration information is part of the configuration information of the configuration information of the first operating mode. The second configuration information is part of the configuration information of the configuration information of the second operating mode. In other words, the configuration information contained in the first information is applicable to communications of different QoSs and / or to communications of different types of terminal devices and is public. Therefore, the configuration information contained in the first information may also be referred to as public configuration information, or public-level configuration information, or shared configuration information, etc., without limitation. For example, the first configuration information may be public configuration information of the first operating mode. For example, the second configuration information may be public configuration information of the second operating mode.

[0137] The operating energy consumption of the first operating mode is less than that of the second operating mode. For example, the first operating mode may be the default mode in the single RRC state, and the second operating mode may be the enhanced mode in the single RRC state. For related introductions, please refer to the above content and will not be repeated here.

[0138] The first configuration information may include one or more of the following: configuration information for a signaling radio bearer (SRB) of a certain type, paging configuration, cell reselection configuration, common channel state information-reference signal (CSI-RS) configuration information for measurements in a first operating mode, configuration information for a common search space for different types of terminal devices and / or for different QoS, configuration information for a wake-up signal, or configuration information for initial access, etc.

[0139] The second configuration information may include one or more of the following: configuration information for SRB of a passing type, measurement configuration information, common CSI-RS configuration information for measurements in the second operating mode, configuration information for common search spaces for different types of terminal devices and / or for different QoS, configuration information for wake-up signals, or configuration information for initial access, etc.

[0140] It is understood that the first configuration information and the second configuration information may include the same information items, but the values ​​of the information items may be different. For example, the first configuration information and the second configuration information may both include configuration information for a pass-through SRB, but the value of the configuration information for the pass-through SRB included in the first configuration information may be different from the value of the configuration information for the pass-through SRB included in the second configuration information.

[0141] It is understandable that the first configuration information and the second configuration information may be broadcast via a first system message, or the first configuration information and the second configuration information may be broadcast via different system messages, without limitation.

[0142] S302: The network device sends a first dedicated signaling to the first terminal device.

[0143] Accordingly, the first terminal device receives the first dedicated signaling from the network device.

[0144] The first dedicated signaling may be, for example, RRC signaling, etc., but is not limited thereto. The first dedicated signaling may carry second information. The second information may be used for communication of the first QoS, or the second information may be used for communication of the first type of terminal device, or the second information may be used for communication of the first QoS and communication of the first type of terminal device. The first QoS belongs to multiple QoSs, that is, the multiple QoSs include the first QoS. The first type belongs to multiple types, that is, the multiple types include the first type. In the embodiment of the present application, the type of the first terminal device is the first type. Please refer to the aforementioned content for the type of the terminal device and will not be repeated here. The QoS requirement of the service of the first terminal device is the first QoS.

[0145] The second information may include the third configuration information of the first operating mode, or the second information may include the fourth configuration information of the second operating mode, or the second information may include the third configuration information of the first operating mode and the fourth configuration information of the second operating mode. FIG3 is taken as an example in which the second information is used for communication of the first QoS, and the second information includes the third configuration information of the first operating mode and / or the fourth configuration information of the second operating mode. The third configuration information is different from the first configuration information. The fourth configuration information is different from the second configuration information. In other words, the configuration information contained in the second information is applicable to communication of the first QoS and / or to communication of the first type of terminal device, and is dedicated compared to the first information. Therefore, the configuration information contained in the second information can also be referred to as dedicated configuration information, or UE-level configuration information, etc., without limitation. For example, the third configuration information can be dedicated configuration information for the first operating mode. For example, the fourth configuration information can be dedicated configuration information for the second operating mode.

[0146] The third configuration information may include one or more of the following: configuration information of configured grant (CG), configuration information of physical uplink control channel (PUCCH), configuration information of physical downlink control channel (PDCCH), configuration information of physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH) (for example, precoding, resource allocation, modulation and coding scheme (MCS) table, or additional demodulation reference signal (DMRS), etc.), or configuration information of CSI-RS. Etc.

[0147] The fourth configuration information may include one or more of the following: configuration information of CG, configuration information of PUCCH, configuration information of PDCCH, configuration information of PUSCH or PDSCH (for example, precoding, resource allocation, MCS table, etc., or additional DMRS, etc.), or configuration information of CSI-RS.

[0148] It is understandable that the third configuration information and the fourth configuration information may include the same information items, but the values ​​of the information items may be different. For example, the third configuration information and the fourth configuration information may both include CG configuration information, and the value of the CG configuration information included in the third configuration information is different from the value of the CG configuration information included in the fourth configuration information.

[0149] In one embodiment, the first information may include the first configuration information or the first configuration information and the second configuration information, and the second information may include the third configuration information, so that the first terminal device can obtain the configuration information of the first operating mode in advance. In another embodiment, the first information may include the second configuration information or the first configuration information and the second configuration information, and the second information may include the fourth configuration information, so that the first terminal device can obtain the configuration information of the second operating mode in advance. In yet another embodiment, the first information may include the first configuration information and the second configuration information, and the second information may include the third configuration information and the fourth configuration information, so that the first terminal device can obtain the configuration information of the first operating mode and the configuration information of the second operating mode in advance.

[0150] The first information includes the first configuration information of the first operating mode, and the second information includes the third configuration information of the first operating mode. This can be replaced by: the first information includes part of the configuration information of the first operating mode, and the second information includes the remaining configuration information of the first operating mode; or it can be replaced by: the first information includes part of the configuration information of the first operating mode, and the second information includes the remaining configuration information of the first operating mode; or it can be replaced by: the first information includes public configuration information of the first operating mode, and the second information includes dedicated configuration information of the first operating mode. Similarly, the first information includes the second configuration information of the second operating mode, and the second information includes the fourth configuration information of the second operating mode. This can be replaced by: the first information includes part of the configuration information of the second operating mode, and the second information includes the remaining configuration information of the second operating mode; or it can be replaced by: the first information includes part of the configuration information of the second operating mode, and the second information includes the remaining configuration information of the second operating mode; or it can be replaced by: the first information includes public configuration information of the second operating mode, and the second information includes dedicated configuration information of the second operating mode. The first information includes the first configuration information of the first operating mode and the third configuration information of the second operating mode. For the replacement description of the second information including the third configuration information of the first operating mode and / or the fourth configuration information of the second operating mode, please refer to the above content and no further details will be given.

[0151] Taking the first operation mode as the default mode and the second operation mode as the enhanced mode as an example, part of the configuration information of the default mode and the configuration information of the enhanced mode (i.e., the first information) is carried by the system message, and the other part (i.e., the second information) is carried by the dedicated signaling. The first information includes part of the configuration information of the default mode (i.e., the first configuration information) and part of the configuration information of the enhanced mode (i.e., the second configuration information), and the second information includes other configuration information of the default mode (i.e., the third configuration information) and other configuration information of the enhanced mode (i.e., the fourth configuration information). Among them, the first information is used for communication of multiple types of terminal devices, and the second information is used for communication of the first type of terminal device, as shown in (1) in Figure 4; or, the first information is used for communication of multiple QoS, and the second information is used for communication of the first QoS, as shown in (2) in Figure 4; or, the first information is used for communication of multiple types of terminal devices and for communication of multiple QoS, and the second information is used for communication of the first type of terminal device and for communication of the first QoS. Please refer to the content shown in Figure 4. FIG4 (1) shows an example in which multiple types of terminal devices include type 1 UE, type 2 UE, and type 3 UE, and the first type of terminal device is type 2 UE. FIG4 (2) shows an example in which multiple QoS include QoS 1, QoS 2, and QoS 3, and the first QoS is QoS 3.

[0152] It is understandable that the third configuration information and the fourth configuration information can be carried by the first dedicated signaling; or, the third configuration information and the fourth configuration information can also be carried by different dedicated signalings, without limitation. For example, the first information includes the first configuration information and the second configuration information. The network device can first send dedicated signaling 1 to the first terminal device, and the dedicated signaling 1 carries the third configuration information; when the second condition is met (for example, there is a transmission demand for a big data service, etc.), the network device then sends dedicated signaling 2 to the first terminal device, and the dedicated signaling 2 carries the fourth configuration information. In this way, the first terminal device can first communicate through the first operating mode to reduce power consumption, and then be conditionally configured to the second operating mode. For another example, the first information includes first configuration information and second configuration information. The network device can first send dedicated signaling 2 to the first terminal device, and the dedicated signaling 2 carries fourth configuration information; when the third condition is met (for example, there is no transmission demand for big data services, etc.), the network device then sends dedicated signaling 1 to the first terminal device, and the dedicated signaling 1 carries the third configuration information. In this way, the first terminal device can first communicate through the second operating mode to ensure the reliability of data transmission, and then be conditionally configured with the first operating mode.

[0153] In the above-mentioned first communication method, the first terminal device can obtain the configuration information of the first operating mode and / or the configuration information of the second operating mode through the first information carried by the first system message and the second information carried by the first dedicated signaling. The first information is used for communication of multiple QoS, and the second information is used for communication of the first QoS, which means that the network device can realize the configuration of the first operating mode and / or the second operating mode of multiple terminal devices by storing the first information and the second information for different QoS. Compared with the need to store the configuration information of the first operating mode and the configuration information of the second operating mode for each terminal device, the above-mentioned embodiment of the present application can reduce the storage information of the network device, enable the network device to provide services to more terminal devices within a limited storage space, and help improve the communication performance of the network device.

[0154] In the embodiment shown in Figure 3 , the network device configures the first operation mode and / or the second operation mode for the first terminal device. In another possible implementation, the network device may also configure a signaling radio bearer (SRB) for the first terminal device, as shown in Figure 5 .

[0155] FIG5 exemplarily illustrates a flow chart of a second communication method provided in an embodiment of the present application. In this embodiment, a network device can configure SRBs for multiple terminal devices by storing a small amount of SRB configuration information, thereby reducing the amount of information stored by the network device. As shown in FIG5 , the second communication method may include the following.

[0156] S501: The network device sends a second system message. For example, the network device may broadcast the second system message.

[0157] Accordingly, the first terminal device receives the second system message.

[0158] In this embodiment, the network device can configure the SRB for the first terminal device in two ways, which are respectively recorded as Method 1 (i.e., S501) and Method 2 (i.e., S502 and S503). In other words, the network device can execute S501, or it can also execute S502 and S503, which are represented by dotted boxes in Figure 5.

[0159] The second system message may be, for example, a SIB, but is not limited thereto. The second system message may carry third information. This third information may be used for communication of at least one QoS (or at least one QoS list), and may include configuration information of SRBs corresponding to at least one QoS; or, the third information may be used for communication of at least one type of terminal device, and may include configuration information of SRBs corresponding to at least one type of terminal device; or, the third information may be used for communication of at least one QoS and for communication of at least one type of terminal device, and may include configuration information of SRBs corresponding to at least one QoS and configuration information of SRBs corresponding to at least one type of terminal device. FIG5 illustrates an example in which the third information is used for communication of at least one QoS, and the third information includes configuration information of SRBs corresponding to the at least one QoS. Communication of at least one QoS may be understood as communication with at least one QoS requirement, or communication with at least one service requiring QoS. For the types of terminal devices, please refer to the description of S301 and will not be further elaborated. SRBs corresponding to at least one QoS may be understood as SRBs applicable to the at least one QoS, or as SRBs that meet the at least one QoS requirement, etc. SRBs corresponding to at least one type of terminal device may be understood as SRBs applicable to the at least one type of terminal device, etc.

[0160] In one embodiment, the at least one QoS may include a first QoS. For example, the QoS requirement of the service of the first terminal device is the first QoS. After receiving the second system message, the first terminal device may obtain the configuration information of the SRB corresponding to the first QoS. Optionally, the at least one QoS may belong to multiple QoS, that is, the multiple QoS include at least one QoS. Please refer to the description of S301 for the multiple QoS and will not be repeated here.

[0161] In one embodiment, the at least one type may include a first type. For example, the type of the first terminal device is the first type. After receiving the second system message, the first terminal device may obtain the configuration information of the SRB corresponding to the first type of terminal device. Optionally, the at least one type of terminal device may belong to multiple types of terminal devices, that is, the multiple types of terminal devices include at least one type of terminal device. Please refer to the description of S301 for the multiple types of terminal devices and will not be repeated here.

[0162] It is understood that a system message can carry (or bear) configuration information for SRBs corresponding to multiple QoSs (and / or multiple types of terminal devices), that is, the third information is used for communication of multiple QoSs (and / or multiple types of terminal devices), and the third information includes configuration information for SRBs corresponding to multiple QoSs (and / or multiple types of terminal devices); or, a system message can carry configuration information for SRBs corresponding to only one QoS (and / or one type of terminal device), that is, the third information is used for communication of one QoS (and / or one type of terminal device), and the third information may include configuration information for SRBs corresponding to one QoS (and / or one type of terminal device), without limitation. A system message carries configuration information for SRBs corresponding to one QoS (and / or one type of terminal device). In other words, configuration information for SRBs corresponding to different QoSs (and / or different types of terminal devices) can be carried by different system messages. In this case, the network device can send different system messages for different QoSs (and / or different types of terminal devices), that is, S501 can be executed multiple times to implement configuration of SRBs for different QoSs (and / or different types of terminal devices).

[0163] The third information being used for communication with multiple QoS levels can also be expressed as: the third information being used for communication with different QoS levels. The third information being used for communication with multiple types of terminal devices can also be expressed as: the third information being used for communication with different types of QoS levels. The third information being used for communication with multiple QoS levels and for communication with multiple types of terminal devices can also be expressed as: the third information being used for communication with different QoS levels and for communication with different types of terminal devices.

[0164] Exemplarily, the SRB may include SRB1, or SRB2, or both SRB1 and SRB2. Accordingly, the SRB configuration information may include configuration information of SRB1, or configuration information of SRB2, or configuration information of SRB1 and SRB2. In other words, the third information may include configuration information of SRB1 corresponding to at least one QoS; or, the third information may include configuration information of SRB2 corresponding to at least one QoS; or, the third information may include configuration information of SRB1 corresponding to at least one QoS and configuration information of SRB2 corresponding to at least one QoS; or, the third information may include configuration information of SRB1 corresponding to at least one type of terminal device; or, the third information may include configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include configuration information of SRB1 corresponding to at least one type of terminal device and configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include configuration information of SRB1 corresponding to at least one QoS and configuration information of SRB1 corresponding to at least one type of terminal device; or, the third information may include configuration information of SRB2 corresponding to at least one QoS and configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include configuration information of SRB1 corresponding to at least one QoS, configuration information of SRB2 corresponding to at least one QoS, configuration information of SRB1 corresponding to at least one type of terminal device and configuration information of SRB2 corresponding to at least one type of terminal device.

[0165] The SRB configuration information may include one or more of the following: SRB ID, configuration information of the PDCP associated with the SRB, or configuration information of the RLC bearer (e.g., logical channel ID, RLC configuration information, or MAC logical channel configuration information). The SRB2 configuration information may include one or more of the following: SRB2 ID, configuration information of the PDCP associated with SRB2, or configuration information of the RLC bearer (e.g., logical channel ID, RLC configuration information, or MAC logical channel configuration information). For details about the SRB1 configuration information and the SRB2 configuration information, please refer to 3GPP TS 38.331 and will not be repeated here.

[0166] In the above-mentioned S501, the first terminal device can obtain the configuration information of the SRB corresponding to at least one QoS through the third information carried by the second system message. This third information is used for the communication of at least one QoS, which means that the network device can configure the SRB corresponding to at least one QoS of multiple terminal devices through the third information. Compared with the need to store the SRB configuration information for each terminal device, the above-mentioned embodiment of the present application can reduce the storage information of the network device, enabling the network device to provide services to more terminal devices within a limited storage space, which is conducive to improving the communication performance of the network device.

[0167] S502: The network device sends a third system message. For example, the network device may broadcast the third system message.

[0168] Accordingly, the first terminal device receives the third system message.

[0169] The third system message may be, for example, an SIB, but is not limited thereto. The third system message may carry fourth information. The fourth information may be used for communication of one or more QoS (or one or more QoS lists), or the fourth information may be used for communication of one or more types of terminal devices, or the fourth information may be used for communication of one or more QoS and for communication of one or more types of terminal devices. For ease of understanding, the following description will be given using the example of the fourth information being used for communication of multiple QoS and / or multiple types of terminal devices. Alternatively, it may be stated as follows: the fourth information may be used for communication of different QoS, or the fourth information may be used for communication of different types of terminal devices, or the fourth information may be used for communication of different QoS and for communication of different types of terminal devices. Among them, communication of multiple QoS may be understood as communication of multiple QoS requirements, or as communication of services of multiple QoS requirements. Communication of different QoS may be understood as communication of different QoS requirements, or as communication of services of different QoS requirements. For various types of terminal devices, please refer to the description of S301 and will not go into details.

[0170] The fourth information may include the fifth configuration information for SRBs corresponding to multiple QoSs, or the fourth information may include the seventh configuration information for SRBs corresponding to multiple types of terminal devices, or the fourth information may include the fifth configuration information for SRBs corresponding to multiple QoSs and the seventh configuration information for SRBs corresponding to multiple types of terminal devices. FIG5 illustrates an example in which the fourth information is used for communications with multiple QoSs, and the fourth information includes the fifth configuration information for SRBs corresponding to the multiple QoSs. The fifth configuration information can be understood as partial configuration information for the SRBs corresponding to the multiple QoSs. The seventh configuration information can be understood as partial configuration information for the SRBs corresponding to the multiple types of terminal devices. In other words, the configuration information included in the fourth information is applicable to communications with different QoSs and / or adapted to communications with different types of terminal devices and is public. Therefore, the configuration information included in the fourth information may also be referred to as public configuration information, or public-level configuration information, or shared configuration information, etc., without limitation. For example, the fifth configuration information may be public configuration information for SRBs corresponding to multiple QoSs. For example, the seventh configuration information may be public configuration information for SRBs corresponding to multiple types of terminal devices.

[0171] Exemplarily, the SRB may include SRB1, or include SRB2, or include SRB1 and SRB2. Accordingly, the fifth configuration information may be understood as the common configuration information of SRB1 corresponding to multiple QoS, or as the common configuration information of SRB2 corresponding to multiple QoS, or as the common configuration information of SRB1 corresponding to multiple QoS and the common configuration information of SRB2 corresponding to multiple QoS. The seventh configuration information may be understood as the common configuration information of SRB1 corresponding to multiple types of terminal devices, or as the common configuration information of SRB2 corresponding to multiple types of terminal devices, or as the common configuration information of SRB1 corresponding to multiple types of terminal devices and the common configuration information of SRB2 corresponding to multiple types of terminal devices.

[0172] The public configuration information of SRB1 may include one or more of the following: configuration information of the PDCP associated with SRB1, configuration information of the RLC bearer associated with SRB1, configuration information of the RLC associated with SRB1, or configuration information of the logical channel associated with SRB1. The public configuration information of SRB2 may include one or more of the following: configuration information of the PDCP associated with SRB2, configuration information of the RLC bearer associated with SRB2, configuration information of the RLC associated with SRB2, or configuration information of the logical channel associated with SRB2.

[0173] S503: The network device sends a second dedicated signaling to the first terminal device.

[0174] Accordingly, the first terminal device receives the second dedicated signaling from the network device.

[0175] The second dedicated signaling may be RRC signaling, etc., but is not limited thereto. The second dedicated signaling may carry the fifth information. The fifth information may be used for communication of the first QoS, or the fifth information may be used for communication of the first type of terminal device, or the fifth information may be used for communication of the first QoS and for communication of the first type of terminal device. The first QoS belongs to multiple QoS, that is, multiple QoS include the first QoS. The first type belongs to multiple types, that is, multiple types include the first type. In the embodiment of the present application, the type of the first terminal device is the first type. Please refer to the aforementioned content for the type of the terminal device and will not be repeated here. The QoS requirement of the service of the first terminal device is the first QoS.

[0176] The fifth information may include the sixth configuration information of the SRB corresponding to the first QoS, or the fifth information may include the eighth configuration information corresponding to the first type of terminal device, or the fifth information may include the sixth configuration information of the SRB corresponding to the first QoS and the eighth configuration information corresponding to the first type of terminal device. FIG5 takes the example of the fifth information being used for communication of the first QoS among multiple QoSs, and the fifth information including the sixth configuration information of the SRB corresponding to the first QoS. Among them, the sixth configuration information is different from the configuration information of the SRB corresponding to the first QoS contained in the fifth configuration information. The eighth configuration information is different from the configuration information of the SRB corresponding to the first type of terminal device contained in the seventh configuration information. In other words, the configuration information contained in the fifth information is applicable to communication of the first QoS and / or to communication of the first type of terminal device, and is dedicated. Therefore, the configuration information contained in the fifth information can also be called dedicated configuration information, or UE-level configuration information, etc., without limitation. For example, the sixth configuration information can be dedicated configuration information of the SRB corresponding to the first QoS. For example, the eighth configuration information can be dedicated configuration information of the SRB corresponding to the first type of terminal device.

[0177] Exemplarily, the SRB may include SRB1, or include SRB2, or include SRB1 and SRB2. Accordingly, the sixth configuration information may be understood as the dedicated configuration information of SRB1 corresponding to the first QoS, or as the dedicated configuration information of SRB2 corresponding to the first QoS, or as the dedicated configuration information of SRB1 corresponding to the first QoS and the dedicated configuration information of SRB2 corresponding to the first QoS. The eighth configuration information may be understood as the dedicated configuration information of SRB1 corresponding to the first type of terminal device, or as the dedicated configuration information of SRB2 corresponding to the first type of terminal device, or as the dedicated configuration information of SRB1 corresponding to the first type of terminal device and the dedicated configuration information of SRB2 corresponding to the first type of terminal device.

[0178] The dedicated configuration information of SRB1 may include one or more of the following: configuration information of the RLC bearer associated with SRB1, the logical channel identifier associated with SRB1, RLC configuration information associated with SRB1, or logical channel configuration information associated with SRB1. The dedicated configuration information of SRB2 may include one or more of the following: configuration information of the RLC bearer associated with SRB2, the logical channel identifier associated with SRB2, RLC configuration information associated with SRB2, or logical channel configuration information associated with SRB2.

[0179] In one embodiment, the fourth information may include the fifth configuration information or include the fifth configuration information and the seventh configuration information, and the fifth information may include the sixth configuration information, so that the first terminal device can obtain the configuration information of the SRB corresponding to the first QoS. In another embodiment, the fourth information may include the seventh configuration information or include the fifth configuration information and the seventh configuration information, and the fifth information may include the eighth configuration information, so that the first terminal device can obtain the configuration information of the SRB corresponding to the first type of terminal device. In another embodiment, the fourth information may include the fifth configuration information and the seventh configuration information, and the fifth information may include the sixth configuration information and the eighth configuration information, so that the first terminal device can obtain the configuration information of the SRB corresponding to the first QoS and the configuration information of the SRB corresponding to the first type of terminal device.

[0180] It should be noted that the fifth configuration information and the seventh configuration information may be different or the same, without limitation. The sixth configuration information and the eighth configuration information may be different or the same, without limitation.

[0181] In the above S502 and S503, the first terminal device can obtain the configuration information of the SRB corresponding to the first QoS through the fourth information carried by the third system message and the fifth information carried by the second dedicated signaling. The fourth information is used for communication of multiple QoS, and the fifth information is used for communication of the first QoS, which means that the network device can configure the SRB corresponding to different QoS of multiple terminal devices through the fourth information and the fifth information for different QoS. Compared with the need to store the configuration information of the SRB for each terminal device, the above embodiment of the present application can reduce the storage information of the network device, enable the network device to provide services to more terminal devices within a limited storage space, and help improve the communication performance of the network device.

[0182] In a possible implementation, the network device may release (or delete) the context of the first terminal device, thereby reducing its own stored information.

[0183] Figure 6 exemplarily illustrates a flow chart of a third communication method provided in an embodiment of the present application. In this embodiment, the network device may release the context of the first terminal device, and the first terminal device may release the context. As shown in Figure 6 , the third communication method may include the following content.

[0184] S601: The network device releases the context of the first terminal device.

[0185] In this embodiment, the network device can release (or delete) the context of the first terminal device. For example, the network device can actively release the context of the first terminal device. In one embodiment, the network device can release the context of the first terminal device when the fourth condition is met. The fourth condition may include one or more of the following: the storage information of the network device reaches a set threshold, the number of terminal devices served (or maintained) by the network device reaches a set threshold, or the first terminal device is in the first operating mode, etc. It can be understood that the embodiment of the present application does not limit the triggering conditions for the network device to release the context of the first terminal device. In addition, the embodiment of the present application does not limit the specific implementation process of the network device selecting which terminal device or terminals to release the context. For example, the first terminal device is in the RRC inactive state, and the network device can release the context of the first terminal device. For another example, the first terminal device is in the first operating mode, and the network device can release the context of the first terminal device.

[0186] Exemplarily, the context of the first terminal device may include configuration information for the first operating mode, or configuration information for the second operating mode, or configuration information for the first operating mode and configuration information for the second operating mode. The operating energy consumption of the first operating mode is less than the operating energy consumption of the second operating mode. For a description of the first operating mode and the second operating mode, please refer to the relevant content in the embodiment shown in FIG. 3 and will not be repeated here.

[0187] Exemplarily, the context of the first terminal device may include at least one of the following: air interface configuration information, security-related information (for example, a key, or a count value, etc.), mapping of QoS flows and DRBs, C-RNTI, original cell identity (ID), or capability information of the terminal device, etc. For specific reference, please refer to the relevant content in 3GPP TS 38.331, which will not be repeated here.

[0188] S602: The network device sends sixth information to the first terminal device.

[0189] Accordingly, the first terminal device receives the sixth information.

[0190] The sixth information may be used to indicate the release of the context. For example, the sixth information may be used to indicate the first terminal device to release the context. Alternatively, the sixth information may be used to indicate the entry into initial mode. For example, the sixth information may be used to indicate the first terminal device to enter initial mode. The first terminal device in initial mode needs to establish a connection with the network side. During the process of establishing the connection between the first terminal device and the network side, the first terminal device may obtain the context.

[0191] In one embodiment, the sixth information may be carried by a first paging message. That is, the network device sends a first paging message, and the first paging message carries the sixth information. For example, the network device may broadcast the first paging message. Accordingly, the first terminal device may receive the first paging message. Optionally, the sixth information may be a paging cause, and the value of the paging cause may be used to indicate the release of the context, or the value of the paging cause may be used to indicate the entry into initial mode. In this embodiment, the sixth information may indicate that a terminal device (i.e., the first terminal device) releases the context; or, the sixth information may also indicate that multiple terminal devices release the context. In other words, the sixth information may indicate that a terminal device (i.e., the first terminal device) enters initial mode; or, the sixth information may also indicate that multiple terminal devices enter initial mode. For example, the network device may release the context of multiple terminal devices and send a first paging message. The multiple terminal devices include the first terminal device. Optionally, the multiple terminal devices correspond to the same paging reason, or the multiple terminal devices are all in the first operating mode (for example, all in the default mode), or the multiple terminal devices are all in the RRC inactive state, without limitation.

[0192] In another embodiment, the sixth information may be carried by a first short message. That is, the network device sends a first short message, and the first short message carries the sixth information. For example, the network device may broadcast the first short message. Accordingly, the first terminal device may receive the first short message. In this embodiment, the sixth information may instruct a terminal device (i.e., the first terminal device) to release the context; or, the sixth information may also instruct multiple terminal devices to release the context. In other words, the sixth information may instruct a terminal device (i.e., the first terminal device) to enter initial mode; or, the sixth information may also instruct multiple terminal devices to enter initial mode. For example, the network device may release the context of the multiple terminal devices and send the first short message. The multiple terminal devices include the first terminal device. Optionally, the multiple terminal devices are all in the first operating mode (for example, all in default mode), or the multiple terminal devices are all in the RRC inactive state, without limitation.

[0193] Exemplarily, the sixth information may be the first field in the first short message. The value of the first field may include the first value, or include the second value, or include the first value and the second value. The first value may be used to indicate that the terminal device in the first operating mode releases the context (or the first value is used to indicate that the terminal device in the first operating mode enters the initial mode). The second value may be used to indicate that the terminal device in the RRC inactive state releases the context. Optionally, the first value may be 0 and the second value may be 1; or the first value may be 1 and the second value may be 0; or the value of the first field includes the first value but does not include the second value, and the value of the first value may be 1 or 0; or the value of the first field includes the second value but does not include the first value, and the value of the second value may be 1 or 0. The embodiment of the present application does not limit the specific implementation form of the first value and the second value. The first field may be, for example, a UE context release indication field, as shown in Table 1. It will be understood that the embodiment of the present application does not limit the number of bits occupied by the first field and the naming of the first field. For the remaining fields in the short message shown in Table 1 except the UE context release indication field, please refer to the description of the short message in the relevant 3GPP protocol and will not be repeated here.

[0194] Table 1

[0195] In another embodiment, the sixth information may be carried by a first wake-up signal (WUS). That is, the network device may send a first wake-up signal to the first terminal device, and the first wake-up signal carries the sixth information. Accordingly, the first terminal device may receive the first wake-up signal. For example, the sixth information may occupy 1 bit in the first wake-up signal, used to indicate whether the first terminal device releases the context or to indicate whether the first terminal device enters the initial mode. The embodiment of the present application does not limit the specific implementation form of the sixth information. Optionally, the first wake-up signal may be a low power wake-up signal (LP WUS). In other words, the network device may send the sixth information to the first terminal device through a low power module.

[0196] In another embodiment, the sixth information may be carried by downlink control information (DCI). That is, the network device may send a DCI to the first terminal device, and the DCI carries the sixth information; accordingly, the first terminal device may receive the DCI. For example, the sixth information may occupy 1 bit in the DCI to indicate whether the first terminal device releases the context or to indicate whether the first terminal device enters the initial mode. The embodiment of the present application does not limit the specific implementation form of the sixth information. Optionally, the DCI may be used to indicate that the first terminal device switches from the second operating mode to the first operating mode, or the DCI may be used to indicate that the first terminal device switches from the first operating mode to the initial mode, or the DCI may be used to indicate that the first terminal device switches from the second operating mode to the initial mode, or the DCI may be used to indicate that the first terminal device switches from the RRC connected state to the RRC inactive state. For example, the DCI may be used to indicate that the first terminal device switches from the enhanced mode to the default mode, or the DCI may be used to indicate that the first terminal device switches from the enhanced mode or the default mode to the initial mode. That is, the network device may reuse the DCI for indicating mode switching to indicate whether the first terminal device releases the context.

[0197] S603: The first terminal device releases the context according to the sixth information.

[0198] After the first terminal device receives the sixth information, it can release (or delete) the context according to the sixth information. For example, the first terminal device enters the initial mode according to the sixth information and releases the context. Optionally, if the first terminal device subsequently receives a paging message or the first terminal device has uplink data, etc., the first terminal device can re-initiate the random access process to obtain the context. For example, the first terminal device can re-acquire the configuration information of the first operating mode and the configuration information of the second operating mode, and enter the first operating mode or the second operating mode as needed.

[0199] In the embodiment shown in FIG6 , the network device releases the context of the first terminal device, which can reduce the storage information of the network device. The first terminal device releases the context in response to the third paging message of the network device, which can reduce the storage information of the first terminal device. In addition, if the first terminal device is in the RRC inactive state, it means that the first terminal device can release the context in the RRC inactive state in response to the sixth information of the network device. Compared with the solution in which the network device first negotiates with the first terminal device and then determines whether to instruct the first terminal device to release the context, the context release process can be simplified, the interaction between the network device and the first terminal device can be reduced, and the utilization rate of network resources can be improved.

[0200] In the embodiment shown in Figure 6 , the network device may proactively release the context of the first terminal device. In another possible implementation, the network device may also release the context of the first terminal device through negotiation with the first terminal device, as shown in Figure 7 .

[0201] Figure 7 illustrates another schematic flow chart of a third communication method provided by an embodiment of the present application. In this embodiment, the network device releases the context of the first terminal device in response to auxiliary information from the first terminal device, and the first terminal device releases the context. As shown in Figure 7, the third communication method may include the following content.

[0202] S701: The network device sends seventh information to the first terminal device.

[0203] Correspondingly, the first terminal device receives the seventh information from the network device.

[0204] The seventh information can be used to request auxiliary information. The auxiliary information is used to determine whether to release the context of the first terminal device. For example, the auxiliary information may include one or more of the following: predicted transmission information, predicted service information (for example, service type, quantity, or transmission delay, etc.), or indication information, etc. The indication information can be used to determine whether to retain (or release) the context of the first terminal device. For example, if the indication information is used to indicate that the context is to be retained, the auxiliary information can be used to determine not to release the context; or, if the indication information is used to indicate that the context is not to be retained, the auxiliary information can be used to determine to release the context.

[0205] In one embodiment, the seventh information can be carried by a second paging message. That is, the network device sends a second paging message, and the second paging message carries the seventh information. For example, the network device can broadcast the second paging message. Correspondingly, the first terminal device can receive the second paging message. Optionally, the seventh information can be a paging cause, and the value of the paging cause can be used to request auxiliary information, or the value of the paging cause can be used to trigger the first terminal device to send auxiliary information. In this embodiment, the seventh information can trigger a terminal device (i.e., the first terminal device) to send auxiliary information; or, the seventh information can also trigger multiple terminal devices to send auxiliary information. The multiple terminal devices include the first terminal device. For example, the multiple terminal devices correspond to the same paging cause, or the multiple terminal devices are all in the first operating mode (for example, all in default mode), without limitation.

[0206] In another embodiment, the seventh information can be carried by a second short message. That is, the network device sends a second short message, and the second short message carries the seventh information. For example, the network device can broadcast the second short message. Correspondingly, the first terminal device can receive the second short message. In this embodiment, the seventh information can trigger a terminal device (i.e., the first terminal device) to send auxiliary information; or, the seventh information can also trigger multiple terminal devices to send auxiliary information. The multiple terminal devices include the first terminal device. For example, the multiple terminal devices are all in the first operating mode (for example, all in the default mode), without limitation.

[0207] Exemplarily, the seventh information may be the second field in the second short message. The value of the second field may include a third value. The third value may be used to trigger the first terminal device to send auxiliary information. The second field may, for example, be a field for triggering the UE to send auxiliary information, as shown in Table 2. It will be understood that the embodiment of the present application does not limit the number of bits occupied by the second field and the naming of the second field. For the remaining fields in the short message shown in Table 2 except for the field for triggering the UE to send auxiliary information, please refer to the description of the short message in the relevant 3GPP protocol, which will not be repeated here.

[0208] Table 2

[0209] In another embodiment, the seventh information may be carried by a second wake-up signal. That is, the network device may send a second wake-up signal to the first terminal device, and the second wake-up signal carries the seventh information. Accordingly, the first terminal device may receive the second wake-up signal. For example, the seventh information may occupy 1 bit in the first wake-up signal to instruct the first terminal device to send auxiliary information. The embodiment of the present application does not limit the specific implementation form of the seventh information. Optionally, the second wake-up signal may be LP WUS. In other words, the network device may send the seventh information to the first terminal device through a low-power module.

[0210] Optionally, the context may include configuration information of the first operation mode, or configuration information of the second operation mode, or configuration information of the first operation mode and configuration information of the second operation mode. For the context, please refer to the relevant description of S601 and will not be repeated here.

[0211] S702: The first terminal device sends auxiliary information to the network device.

[0212] Accordingly, the network device receives the auxiliary information from the first terminal device.

[0213] After receiving the seventh information, the first terminal device may send auxiliary information to the network device. For example, the first terminal device sends auxiliary information to the network device based on the seventh information.

[0214] S703: The network device releases the context of the first terminal device according to the auxiliary information.

[0215] Exemplarily, the network device may determine to release the context of the first terminal device based on the auxiliary information, or the network device may determine not to release (or retain) the context of the first terminal device based on the auxiliary information. In this embodiment, the network device is used as an example to determine to release the context of the first terminal device based on the auxiliary information. Accordingly, the network device may release the context of the first terminal device based on the auxiliary information, where the auxiliary information is used to determine the context to be released.

[0216] In another example, the network device may also consider a fourth condition when determining whether to release the context of the first terminal device. Please refer to the content of S601 for the fourth condition and will not be repeated here. In other words, the network device may determine whether to release the context of the first terminal device based on the auxiliary information from the first terminal device and its own relevant circumstances. For example, if the indication information in the auxiliary information indicates that the context of the first terminal device should be retained, but the stored information of the network device reaches a set threshold, the network device may determine to release the context of the first terminal device based on the auxiliary information and its own relevant circumstances.

[0217] S704: The network device sends sixth information to the first terminal device.

[0218] Accordingly, the first terminal device receives sixth information from the network device.

[0219] The sixth information can be used to indicate the release of the context, that is, the sixth information is used to indicate the first terminal device to release the context. Alternatively, the sixth information can be used to indicate the entry into the initial mode, that is, the sixth information is used to indicate the first terminal device to enter the initial mode. The first terminal device in the initial mode needs to establish a connection with the network side. The first terminal device can obtain the context during the process of establishing the connection between the first terminal device and the network side. In this embodiment, the sixth information can be confirmation information, or the sixth information can be carried by the DCI without restriction.

[0220] S705: The first terminal device releases the context according to the sixth information.

[0221] After the first terminal device receives the sixth information, it can release (or delete) the context according to the sixth information. For example, the first terminal device enters the initial mode according to the sixth information and releases the context. Optionally, if the first terminal device subsequently receives a paging message or the first terminal device has uplink data, etc., the first terminal device can re-initiate the random access process to obtain the context. For example, the first terminal device can re-acquire the configuration information of the first operating mode and the configuration information of the second operating mode, and enter the first operating mode or the second operating mode as needed.

[0222] In the embodiment shown in FIG7 , the network device can release the context of the first terminal device based on the auxiliary information of the first terminal device, thereby reducing the stored information of the network device and reducing the impact on the service of the first terminal device. The first terminal device releases the context in response to the sixth information of the network device, thereby reducing the stored information of the first terminal device.

[0223] In one possible implementation, the network device may release the context of the first terminal device to reduce its own stored information; thereafter, the first terminal device may reacquire the context, as shown in Figure 8. For example, if the network device releases the context of the first terminal device, but the first terminal device does not release the context, the first terminal device may reacquire the context.

[0224] FIG8 exemplarily illustrates a flow chart of a fourth communication method provided in an embodiment of the present application. In this embodiment, the network device releases the context of the first terminal device, and the first terminal device reacquires the context. As shown in FIG8 , the fourth communication method may include the following content.

[0225] S801: The network device releases the context of the first terminal device.

[0226] In this embodiment, the network device may release (or delete) the context of the first terminal device. For a specific implementation process, please refer to the relevant content of S601 and will not be described in detail.

[0227] In this embodiment, the first terminal device can reacquire the context in three ways, which are respectively referred to as Method 1 (i.e., S802 and S803), Method 2 (i.e., S804 and S805), and Method 3 (i.e., S806 and S807). In other words, the first terminal device can execute S802 and S803, or S804 and S805, or S806 and S807, as indicated by dashed boxes in FIG8 .

[0228] S802: The network device sends a third paging message to the first terminal device.

[0229] Accordingly, the first terminal device receives a third paging message from the network device.

[0230] The third paging message carries the eighth information. The eighth information can be used to instruct the first terminal device to obtain the context, or the eighth information can be used to indicate that the context stored by the first terminal device is invalid. The eighth information can be, for example, a paging reason, and the value of the paging reason can be used to instruct the first terminal device to obtain the context, or the value of the paging reason can be used to indicate that the context stored by the first terminal device is invalid. Exemplarily, the network device releases the context of the first terminal device, and the first terminal device does not release the context. When downlink data arrives, the network device can send a third paging message to the first terminal device to instruct the first terminal device to obtain the context. It can be understood that the embodiment of the present application does not limit the triggering conditions for the network device to send the third paging message.

[0231] S803: The first terminal device sends ninth information to the network device according to the eighth information.

[0232] Accordingly, the network device receives ninth information from the first terminal device.

[0233] The ninth information is used to request the context. Exemplarily, after receiving the third paging message, the first terminal device may send the ninth information to the network device according to the eighth information carried in the third paging message to obtain the context.

[0234] S804: The first terminal device sends tenth information to the network device.

[0235] The tenth information can be used to request switching from the first operating mode to the second operating mode; or, the tenth information can be used to request switching from the second operating mode to the first operating mode. For the relevant description of the first operating mode and the second operating mode, please refer to the above content and will not be repeated here. For example, when uplink data arrives, the first terminal device can send the tenth information to the network device. For example, the first terminal device is in the first operating mode, and the amount of uplink data is large. The first terminal device can send the tenth information to the network device to request switching from the first operating mode to the second operating mode. For another example, the first terminal device is in the second operating mode, and the amount of uplink data is small. The first terminal device can send the tenth information to the network device to request switching from the second operating mode to the first operating mode. It can be understood that the embodiment of the present application does not limit the triggering conditions for the first terminal device to send the tenth information to the network device.

[0236] In this embodiment, the tenth message may be successfully received, meaning that the network device receives the tenth message from the first terminal device. Alternatively, the tenth message may fail to be received. For example, if the network device releases the context of the first terminal device but the first terminal device does not, the network device may fail to receive the tenth message. FIG8 illustrates the failure to receive the tenth message as an example. In FIG8 , an "X" indicates the failure to receive the tenth message.

[0237] S805: When the first condition is met, the first terminal device sends ninth information to the network device.

[0238] Accordingly, the network device receives ninth information from the first terminal device.

[0239] The ninth information is used to request a context. In one embodiment, the first condition may be: the response message of the tenth information is used to instruct the first terminal device to obtain the context, or the response message of the tenth information is used to indicate that the context stored by the first terminal device is invalid. For example, the network device releases the context of the first terminal device, and the first terminal device does not release the context. After the network device receives the tenth information of the first terminal device, it may send a response message of the tenth information to the first terminal device. In one example, the response message of the tenth information may be a switching response message based on layer 1. For example, the response message of the tenth information may be carried by DCI. In another example, the response message of the tenth information may be a switching response message based on layer 2. For example, the response message of the tenth information may be carried by a medium access control control element (MAC CE). Accordingly, the first terminal device receives the response message of the tenth information and sends the ninth information to the network device according to the response message of the tenth information.

[0240] In another embodiment, the first condition may be that the number of retransmissions of the tenth information equals (or reaches) a first maximum number of retransmissions. For example, if the network device releases the context of the first terminal device, but the first terminal device does not release the context, the network device may fail to receive the tenth information. When the number of retransmissions of the tenth information equals the first maximum number of retransmissions, the first terminal device may send the ninth information to the network device. The first maximum number of retransmissions may be configured by the network device or predefined and is not subject to limitation.

[0241] In another embodiment, the first condition may be: the timer corresponding to the tenth information has timed out. For example, after the first terminal device sends the tenth information, the timer corresponding to the tenth information may be started. During the operation of the timer corresponding to the tenth information, the first terminal device may wait for a response message to the tenth information. For example, the network device releases the context of the first terminal device, but the first terminal device does not release the context. The network device may fail to receive the tenth information, or may successfully receive the tenth information. If the first terminal device receives a response message to the tenth information during the operation of the timer corresponding to the tenth information, the timer corresponding to the tenth information may be turned off. If the timer corresponding to the tenth information times out, it means that the first terminal device has not received a response message to the tenth information during the operation of the timer corresponding to the tenth information, then the first terminal device sends the ninth information to the network device. The duration of the timer corresponding to the tenth information may be configured by the network device, or may be pre-defined and is not restricted.

[0242] Alternatively, the first condition may also be a combination of any two or three of the above. For example, the first condition may be: the number of retransmissions of the tenth information is equal to the first maximum number of retransmissions, and the timer corresponding to the tenth information times out. For another example, the first condition may be: the response message of the tenth information is used to instruct the first terminal device to obtain the context, and the timer corresponding to the tenth information times out. For another example, the first condition may be: the number of retransmissions of the tenth information is equal to the first maximum number of retransmissions, and the response message of the tenth information is used to instruct the first terminal device to obtain the context. For another example, the first condition may be: the response message of the tenth information is used to instruct the first terminal device to obtain the context, the number of retransmissions of the tenth information is equal to the first maximum number of retransmissions, and the timer corresponding to the tenth information times out. Please refer to the aforementioned content for the specific implementation process and will not be repeated here.

[0243] S806: The first terminal device sends uplink data to the network device.

[0244] Exemplarily, the first terminal device can send uplink data to the network device. In this embodiment, the uplink data reception fails. For example, the network device releases the context of the first terminal device, but the first terminal device does not release the context, so that the network device cannot receive the uplink data. In Figure 8, "×" is used to indicate that the uplink data reception failed. For example, the data volume of the uplink data is small, and the first terminal device sends the uplink data to the network device based on the configuration parameters of the first operating mode, and the network device releases the configuration information of the first operating mode, resulting in the uplink data transmission failure. For another example, the data volume of the uplink data is large, and the first terminal device sends the uplink data to the network device based on the configuration parameters of the second operating mode, and the network device releases the configuration information of the second operating mode, resulting in the uplink data transmission failure.

[0245] S807: When the fifth condition is met, the first terminal device sends ninth information to the network device.

[0246] Accordingly, the network device receives ninth information from the first terminal device.

[0247] The ninth information is used to request a context. In one embodiment, the fifth condition may be: the number of retransmissions of the uplink data is equal to the second maximum number of retransmissions. For example, the network device releases the context of the first terminal device, but the first terminal device does not release the context, and the network device cannot receive the uplink data. When the number of retransmissions of the uplink data is equal to the second maximum number of retransmissions, the first terminal device may send the ninth information to the network device. The second maximum number of retransmissions may be configured by the network device, or may be predefined and is not subject to restriction.

[0248] In another embodiment, the first condition may be: the timer corresponding to the uplink data times out. For example, after the first terminal device sends the uplink data, the timer corresponding to the uplink data may be started. During the operation of the timer corresponding to the uplink data, the first terminal device may wait for a response message of the uplink data. For example, the network device releases the context of the first terminal device, but the first terminal device does not release the context, and the network device cannot receive the uplink data, resulting in the timer corresponding to the uplink data timing out, and the first terminal device sends the ninth information to the network device. The duration of the timer corresponding to the uplink data may be configured by the network device, or may be predefined and is not restricted.

[0249] Alternatively, the fifth condition may also be: the number of retransmissions of the uplink data is equal to the second maximum number of retransmissions, and the timer corresponding to the uplink data times out. For the specific implementation process, please refer to the above content and will not be repeated here.

[0250] In the fourth communication method, the network device releases the context of the first terminal device to reduce its own stored information. Furthermore, the first terminal device can reacquire the context in response to the third paging message from the network device, or when the first or fifth conditions are met. This allows the first terminal device to reacquire the context in a variety of ways, even if the network device has released the context of the first terminal device but the first terminal device has not, providing flexible implementation options.

[0251] It should be noted that the first communication method shown in Figure 3, the second communication method shown in Figure 5, the third communication direction shown in Figure 6 or Figure 7, and the fourth communication method shown in Figure 8 can be used independently or in combination.

[0252] In one example, the first communication method and the second communication method can be used in combination. For example, the network device configures an SRB for the first terminal device according to the second communication method; after the first terminal device completes initial access, it establishes a connection with the core network based on the SRB configuration information. During this time, the network device can configure the first operating mode and / or the second operating mode for the first terminal device according to the first communication method.

[0253] In another example, the first communication method and the third communication method can be used in combination. For example, the network device can configure the first operating mode and the second operating mode for the first terminal device according to the first communication method. Thereafter, the network device and the first terminal device can release the configuration information of the first operating mode and the configuration information of the second operating mode according to the third communication method.

[0254] In another example, the first communication method and the third communication method can be used in combination. For example, the network device can configure the first operating mode and the second operating mode for the first terminal device according to the first communication method. Afterwards, the network device releases the configuration information for the first operating mode and the second operating mode, and the first terminal device can reacquire the configuration information for the first operating mode and the second operating mode according to the fourth communication method.

[0255] In another example, the first communication method, the second communication method, and the third communication method can be used in combination. For example, the network device configures an SRB for the first terminal device according to the second communication method; after the first terminal device completes initial access, it establishes a connection with the core network based on the SRB configuration information. During this period, the network device can configure the first operating mode and the second operating mode for the first terminal device according to the first communication method; thereafter, the network device and the first terminal device can release the configuration information of the first operating mode, the configuration information of the second operating mode, and the SRB configuration information according to the third communication method.

[0256] In another example, the first communication method, the second communication method, and the fourth communication method can be used in combination. For example, the network device configures an SRB for the first terminal device according to the second communication method; after the first terminal device completes initial access, it establishes a connection with the core network based on the SRB configuration information. During this time, the network device can configure the first operating mode and the second operating mode for the first terminal device according to the first communication method; thereafter, the network device can release the context of the first terminal device, and the first terminal device can reacquire the context according to the fourth communication method.

[0257] It is understandable that the other combinations are similar and are not listed here one by one for the sake of brevity.

[0258] It should be noted that when the various communication methods described above are used in combination, the embodiments of the present application do not limit the order in which the various communication methods are executed. For example, the network device may configure a first operating mode and a second operating mode for a first terminal device according to a first communication method; thereafter, the network device and the first terminal device may release the configuration information of the first operating mode and the configuration information of the second operating mode according to a third communication method. Alternatively, the network device and the first terminal device may release the configuration information of the first operating mode and the configuration information of the second operating mode according to a third communication method; thereafter, the network device may reconfigure the first operating mode and the second operating mode for the first terminal device according to the first communication method.

[0259] In the embodiments provided in the present application, the methods provided in the embodiments of the present application are introduced from the perspective of the interaction between the first terminal device and the network device. Among them, the steps performed by the communication device (for example, the first terminal device or the network device) can be implemented by different functional entities that constitute the terminal equipment. The communication device (for example, the first terminal device or the network device) may include a hardware structure and / or a software module to implement the above-mentioned functions in the form of a hardware structure, a software module, or a hardware structure plus a software module. Whether a function of the above-mentioned functions is performed in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

[0260] The following describes the communication device used to implement the above method in the embodiment of the present application with reference to the accompanying drawings. Therefore, the above contents can be used in subsequent embodiments, and repeated contents will not be repeated.

[0261] Figure 9 illustrates a schematic structural diagram of a communication device 900. The communication device 900 can implement the functions or steps implemented by the first terminal device or network device in each of the above-described method embodiments. For example, the communication device 900 can be a network device or a component thereof (such as a DU), or a terminal device or a component thereof.

[0262] In one embodiment, the communication device 900 may include a processing module 901 and a transceiver module 902.

The processing module 901 may also be referred to as a processing unit. The transceiver module 902 may be used to implement corresponding communication functions, such as receiving or sending relevant data, information, or messages. The transceiver module 902 may also be referred to as a communication interface, a communication module, or a transceiver unit.

[0263] It should be noted that the communication device 900 may include the processing module 901 but not the transceiver module 902. Alternatively, the communication device 900 may include the transceiver module 902 but not the processing module 901. The specific implementation depends on whether the above solution executed by the communication device 900 includes both processing and transceiver actions.

[0267] Optionally, the communication device 900 is a chip system, the transceiver unit may be an input and output interface of a chip (eg, a baseband chip), and the processing unit may be a processor of the chip system.

[0268] In a first implementation manner, the communication device 900 may be a first terminal device, a chip used in the first terminal device, or other combined devices, components, etc. having the functions of the first terminal device.

[0269] In one example, the communication device 900 can execute the following: the transceiver module 902 can be used to receive a first system message, the first system message carries first information, and the first information is used for communication of multiple QoS; and, receive a first dedicated signaling from a network device, the first dedicated signaling carries second information, the second information is used for communication of a first QoS, and the first QoS belongs to multiple QoS; wherein the first information includes first configuration information of a first operating mode and second configuration information of a second operating mode, the second information includes third configuration information of the first operating mode and / or fourth configuration information of the second operating mode, the operating energy consumption of the first operating mode is less than the operating energy consumption of the second operating mode, the first configuration information is different from the third configuration information, and the second configuration information is different from the fourth configuration information.

[0270] In another example, the communication device 900 can execute the following: the transceiver module 902 can be used to receive a second system message, the second system message can carry third information, the third information is used for communication of at least one QoS, and the third information can include configuration information of SRB corresponding to at least one QoS, the SRB includes SRB1, or includes SRB2, or includes SRB1 and SRB2, and the at least one QoS includes the first QoS.
