Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and apparatus. Background Art

[0002] To improve the battery life of a terminal device, on the terminal device side, the terminal device can extend its battery life by using a battery with a larger capacity, components with low power consumption and high performance, or a display screen with power-saving technology; on the network side, on the premise of ensuring the effective data transmission of the terminal device, the 3rd generation partnership project (3GPP) defines a variety of energy-saving communication technologies to reduce the unnecessary power consumption of the terminal device and achieve the purpose of energy saving for the terminal device. One energy-saving communication technology is the single radio resource control state (single RRC state). The single RRC state includes one RRC state, and this RRC state has two working modes, which are respectively called the default mode and the enhanced mode. The enhanced mode is suitable for data transmission with a large amount of data, and the default mode is suitable for data transmission with a small amount of data. Compared with the enhanced mode, the terminal device in the default mode can use fewer antennas, a narrower bandwidth, and fewer links, etc. Therefore, the terminal device in the default mode will have lower power consumption.

[0003] To enable the single RRC state, the terminal device will obtain two sets of configuration information after initial access, which are respectively used for communication in the default mode and communication in the enhanced mode. Correspondingly, the network device needs to store the configuration information of the terminal device in different modes. However, the memory of the network device is limited. If there is too much stored information in the network device, it will cause the maximum number of supported users in the cell to be limited, thereby affecting the communication performance of the network device. Summary of the Invention

[0004] Embodiments of this application provide a communication method and apparatus, which can reduce the stored information of the network device.

[0005] In a first aspect, this application provides a communication method. This method can be executed by a first terminal device, or by other devices including the functions of the first terminal device, or by a chip system (or, chip) or other functional modules. The chip system or functional module can implement the functions of the first terminal device, and the chip system or functional module is, for example, disposed in the first terminal device.

[0006] Taking the first terminal device as an example of the execution entity, the method includes: the first terminal device receives a first system message, the first system message carries first information, and the first information is used for communication of multiple qualities of service (QoS); and, receives a first dedicated signaling from a network device, the first dedicated signaling carries second information, and the second information is used for communication of a first QoS, and the first QoS belongs to the multiple QoSs; wherein, the first information includes first configuration information of a first operation mode and second configuration information of a second operation mode, the second information includes third configuration information of the first operation mode and / or fourth configuration information of the second operation mode, the working energy consumption of the first operation mode is less than that of the second operation mode, the first configuration information is different from the third configuration information, and the second configuration information is different from the fourth configuration information.

[0008] Through the above embodiments, the first terminal device can obtain the configuration information of the first operation mode and / or the configuration information of the second operation mode. The first information is used for communication of multiple QoSs, and the second information is used for communication of the first QoS, which means that the network device can configure the first operation mode and / or the second operation mode of multiple terminal devices by storing the first information and the second information for different QoSs. Compared with the need to store the configuration information of the first operation mode and the configuration information of the second operation mode for each terminal device, the above embodiments of the present application can reduce the stored information of the network device, enable the network device to provide services for more terminal devices within a limited storage space, and is beneficial to improving the communication performance of the network device.

[0009] In a possible implementation manner, the first terminal device may further receive a second system message, the second system message may carry third information, the third information is used for communication of at least one QoS, the third information may include configuration information of a signaling radio bearer (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.

[0010] Through the above implementation, the first terminal device can obtain the configuration information of the SRB corresponding to at least one QoS. This third information is used for 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 configuration information of the SRB for each terminal device, the above implementation can reduce the storage information of the network device, enabling the network device to serve more terminal devices within a limited storage space, which is beneficial to improving the communication performance of the network device.

[0011] In another possible implementation, the first terminal device may also receive a third system message, which carries fourth information for communication of multiple QoSs; and receive a second dedicated signaling from the network device, which carries fifth information for communication of the first QoS. Among them, the fourth information includes the fifth configuration information of the SRB corresponding to multiple QoSs, the fifth information includes the sixth configuration information of the SRB corresponding to the first QoS, the configuration information of the SRB corresponding to the first QoS included in the fifth configuration information is different from the sixth configuration information, the SRB includes SRB1 and / or SRB2, the SRB includes SRB1, or includes SRB2, or includes SRB1 and SRB2.

[0012] Through the above implementation, the first terminal device can obtain the configuration information of the SRB corresponding to the first QoS.

The context may include the configuration information of the first operation mode, or include the configuration information of the second operation mode, or include the configuration information of the first operation mode and the second operation mode.

[0014] Through the above implementation, the first terminal device can release the context in response to the sixth information from the network device, reducing the stored information of the first terminal device. The sixth information comes from the network device, which means that the network device can also release the context, thereby reducing the stored information of the network device. In addition, the sixth information is carried by a paging message or a short message or a wake-up signal, enabling the first terminal device to receive the sixth information from the network device even if the network device has released the context of the first terminal device.

[0020] In another possible implementation, the first terminal device may further send tenth information to the network device. The tenth information may be used to request a switch from the first operating mode to the second operating mode, or the tenth information may be used to request a switch from the second operating mode to the first operating mode; when a first condition is met, the ninth information is sent to the network device, and the ninth information is used to request context, where the context may include configuration information of the first operating mode, or may include configuration information of the second operating mode, or may include configuration information of the first operating mode and configuration information of the second operating mode. The first condition may include one or more of the following: the response message of the tenth information may be used to instruct the first terminal device to obtain context, the retransmission count of the tenth information is equal to the first maximum retransmission count, or the timer corresponding to the tenth information expires.

In view of this, "a plurality of" in the embodiments of the present application may also be understood as "at least two". "At least one" can be understood as one or more, for example, understood as one, two or more. For example, "including at least one" means including one, two or more. For example, including at least one of A, B, and C, then what can be included is A, B, C, A and B, A and C, B and C, or A, B, and C. "And / or" describes the association relationship of associated objects. Specifically, there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / ", unless otherwise specified, generally represents an "or" relationship between the associated objects before and after.

[0106] In addition, the terms "system" and "network" in the embodiments of the present application can be used interchangeably, and "according to" and "based on" can be used interchangeably.

[0107] The ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are usually used to distinguish different objects, and are not used to limit the order, time sequence, priority or importance of multiple objects, etc. For example, the first information and the second information in the embodiments of the present application are used to distinguish two pieces of information, and do not limit the priority or importance of these two pieces of information, etc.

[0108] The embodiments of the present application will be presented around a system including a plurality of 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 mentioned in the embodiments.

[0109] First, the communication system applicable to the embodiments of the present application will be introduced below.

[0110] The technical solutions of the embodiments of this 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, vehicle networking 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), worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems (such as new radio (NR) systems), future communication systems (such as 6th generation (6G) mobile communication systems), or other similar communication systems, without limitation. The embodiments of this application will be described by taking the Figure 1 shown communication system as an example. When applying the technical solutions of the embodiments of this application to other communication systems, the devices, components, modules, etc. in the embodiments can be replaced with the corresponding devices, components, modules in other communication systems, without limitation.

[0111] Figure 1 is a schematic diagram of the architecture of the communication system to which the embodiments of this application are applied. As Figure 1 shown, the communication system 1000 includes an access network 100 and a core network 200. Optionally, the communication system 1000 may further include the Internet 300. Among them, the access network 100 may include at least one radio access network (RAN) node, such as Figure 1 110a and 110b in Figure 1Among 120a - 120j. Among them, 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 fuel dispenser, 120d is a home access point (HAP) deployed indoors or outdoors, 120g is a laptop, 120h is a printer, and 120i is a drone. Among them, the same terminal device or network device can provide different functions in different application scenarios. For example, Figure 1 The mobile phones among them are 120a, 120e, 120f and 120j. The mobile phone 120a can access the base station 110a, connect to the car 120b, directly communicate with the mobile phone 120e, and access the HAP. The car 120b can access the HAP and directly communicate with the mobile phone 120a. The mobile phone 120f can access the micro station 110b, connect to the laptop 120g, and connect to the printer 120h. The mobile phone 120j can control the drone 120i.

[0112] A network device is a network - side device with wireless transceiver functions, which can be an access network device or also a core network device. For the sake of easy 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 a network device, etc. RAN can be an access network in the 3rd generation partnership project (3GPP), for example, a 4G, 5G, or future - oriented 6G network.

[0113] RAN can also be an open RAN (O - RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. A RAN device 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, etc.

[0114] The RAN device can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete some or all of the functions of the physical layer. For the specific descriptions of the above protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The CU and DU can be set separately, or can also be included in the same network element, such as the baseband unit (BBU). The RU can be included in the radio frequency device or radio frequency unit, such as included in the remote radio unit (RRU), the active antenna unit (AAU), or the remote radio head (RRH). In different systems, the CU, DU, or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be called O-CU (open CU), the DU can also be called O-DU, and the RU can also be called O-RU. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The network device can be a macro base station (such as Figure 1 110a in Figure 1 ), or a micro base station or an indoor station (such as

[0115] 110b in

[0116] Figure 1 ), or a relay node or a donor node, etc. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the network device.

[0115] In the embodiments of this application, the functions of the network device can also be executed by a module (such as a chip) in the network device, or can also be executed by a control subsystem including the functions of the network device. Here, the control subsystem including the functions of the network device can be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city.

[0116] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device can also be referred to as a terminal, a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. A terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. In the embodiments of this application, the device for implementing the functions of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device to implement such functions, such as a chip system or a combined device or component that can implement the functions of the terminal device. This device can be installed in the terminal device. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0117] In the embodiments of this application, the functions of the terminal device can also be executed by modules (such as chips or modems) in the terminal device, or by a device containing the functions of the terminal device.

[0118] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; they can also be deployed on water; and can also be deployed on airplanes, balloons, and artificial satellites in the air. The embodiments of this application do not limit the application scenarios of the network device and the terminal device.

[0119] The roles of the network device and the terminal device can be relative. For example, Figure 1 the helicopter or drone 120i in [description] can be configured as a mobile network device. For the terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, both the network device and the terminal device can be uniformly referred to as communication devices. Figure 1110a and 110b in it can be referred to as communication devices with network device functions. Figure 1 120a - 120j in it can be referred to as communication devices with terminal device functions.

[0120] In one implementation, the embodiments of the present application can be applied to a standalone (SA) scenario or a non - standalone NSA scenario. Figure 2a Fig. shows a schematic diagram of a SA communication system. The 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 5G Core, the access network device is a 5G access network device, and the 5G access network device is directly connected to 5G Core. Another example, the core network is 6G Core, the access network device is a 6G access network device, and the 6G access network device is directly connected to 6G Core.

[0121] In another implementation, the embodiments of the present application can also be applied to a dual - connectivity (DC) scenario. Figure 2b Fig. shows a schematic diagram of a DC communication system. The terminal device is simultaneously connected to access network devices of different / same standards. For example, the core network is 5GCore, the terminal device is simultaneously connected to a 5G access network device and a 6G access network device, where the 5G access network device is the master station and the 6G access network device is the secondary station. Another example, the core network is 6G Core, the terminal device is simultaneously connected to a 6G access network device and a 5G access network device, where the 6G access network device is the master station and the 5G access network device is the secondary station. Another example, the core network is 6G Core, the terminal device is simultaneously connected to two 6G access network devices, that is, both the master station and the secondary station are 6G access network devices.

[0122] Next, the technical features involved in the embodiments of the present application will be introduced.

[0123] Compared with the LTE communication system, in order to enable the terminal device to return to the radio resource control (RRC) connected state more quickly, in addition to supporting the RRC idle state and the RRC connected state, the NR communication system also introduces the RRC inactive state. The access network device (e.g., gNodeB) corresponding to the terminal device in the RRC inactive state maintains the context of the terminal device. That is to say, the air interface state of the terminal device in the RRC inactive state is similar to the air interface state in the RRC idle state. From the perspective of the core network side, the terminal device in the RRC inactive state is still in the connection management (CM) state.

[0124] If the terminal device is in the inactive state, the terminal device needs to maintain the context of the inactive state. This context may include, but is not limited to: air interface configuration information, security-related information (e.g., keys, or count values, etc.), the mapping between QoS flows and data radio bearers (DRBs), the Cell-Radio network temporary identifier (C-RNTI), and the original cell identity (ID), etc. For specific content, please refer to the content related to "UE inactive AS context" in the 3GPP relevant protocol, which will not be elaborated here. Correspondingly, the base station side also needs to maintain the context of the terminal device. This context may include, but is not limited to: the capability information of the terminal device, the air interface configuration information of the terminal device, the security capability information of the terminal device, the air interface security information of the terminal device, and protocol data unit (PDU) session resources, etc. For specific content, please refer to the relevant content in "UE Context Information–Retrieve UEContext Response" in the 3GPP relevant protocol, which will not be elaborated here.

[0125] 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 as follows: Different from the three RRC states defined in the NR communication system, the single RRC state only contains one RRC state, and this RRC state has two operating modes, which are respectively called the default mode and the enhanced mode. The enhanced mode is suitable for data transmission with a large amount of data, and the default mode is suitable for data transmission with a small amount of data. Compared with the enhanced mode, the terminal device in the default mode can adopt fewer antennas, a narrower bandwidth, and fewer link or beam detections, etc. Therefore, the terminal device in the default mode will have lower energy consumption. In one implementation, in addition to these two operating modes, the RRC state can also have an initial mode, and the terminal device in the initial mode is not connected to the network side. For example, a newly powered-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 enhanced mode. Optionally, after the terminal device obtains the configuration information of the default mode and the enhanced mode, it can enter the default mode or the enhanced mode as needed. For example, the terminal device can default to enter the default mode.

[0126] It can be understood that for the terminal device in the initial mode, the terminal device has not yet established a connection with the network side. Therefore, the terminal device needs to establish a connection with the network side. During the process of the terminal device establishing a connection with the network side, the terminal device can obtain context. The establishment of a connection between the terminal device and the network side can be understood as: the terminal device establishes a connection with the network device, and / or the terminal device establishes a connection with the core network.

[0127] It should be noted that the default mode can also be called the default state (default state), without limitation. The enhanced mode can also be called the enhanced state (enhanced state), without limitation. The initial mode can also be called the initial state (initial state), without limitation.

[0128] To enable a single RRC state, after initial access, the terminal device obtains two sets of configuration information, which are respectively used for communication in the default mode and communication in the enhanced mode. Correspondingly, the network device needs to store the configuration information of the terminal device in different modes. However, the memory of the network device is limited. If there is too much stored information in the network device, it will cause the maximum number of supported users in the cell to be limited, thereby affecting the communication performance of the network device. Therefore, how to reduce the stored information of the network device and improve the communication performance of the network device is a technical problem that needs to be solved urgently.

[0129] In view of this, an embodiment of the present application provides a communication method and apparatus for reducing the stored information of the network device, which is beneficial to improving the communication performance of the network device. This method can be applied to Figure 1 、 Figure 2a or Figure 2b the communication systems shown, but not limited thereto. For example, the network device may be Figure 1 、 Figure 2a or Figure 2b the network devices shown, or a component in the network device, or other devices including the network device, etc., without limitation. For example, the first terminal device may be Figure 1 、 Figure 2a or Figure 2b the terminal devices shown, or a component in the terminal device, or other devices including the terminal device, etc., without limitation.

[0130] Figure 3 Exemplarily shows a schematic flow diagram of the first communication method provided by an embodiment of the present application. In this embodiment, the network device can configure the first operation mode and / or the second operation mode of multiple terminal devices by storing the first information and the second information for different QoS and / or different types of terminal devices, which can reduce the stored information of the network device. As Figure 3 shown, the first communication method may include the following content.

[0131] S301: The network device sends a first system message. For example, the network device may broadcast the first system message.

[0132] Correspondingly, the first terminal device receives the first system message.

[0133] The first system message can be, for example, a system information block (SIB), but is not limited thereto. The first system message can carry first information. The first information can be used for communication of one or more QoS (or one or more QoS lists), or the first information can be used for communication of one or more types of terminal devices, or the first information can 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 by taking the first information being used for communication of multiple QoS and / or multiple types of terminal devices as an example. Or it can also be expressed as: the first information can be used for communication of different QoS (or different QoS lists), or the first information can be used for communication of different types of terminal devices, or the first information can be used for communication of different QoS and for communication of different types of terminal devices. Among them, communication of multiple QoS can be understood as communication of multiple QoS requirements, or understood as communication of services with multiple QoS requirements. Communication of different QoS can be understood as communication of different QoS requirements, or understood as communication of services with different QoS requirements. Multiple types of terminal devices can include at least two of the following: terminal devices for enhanced mobile broadband (EMBB), terminal devices for ultra-reliable low latency communication (URRLC), terminal devices for reduced capability (RedCap), or terminal devices for massive machine type communications (MMTC), etc., without limitation.

[0134] The first information can include first configuration information of a first operation mode, or the first information can include second configuration information of a second operation mode, or the first information can include first configuration information of a first operation mode and second configuration information of a second operation mode. Figure 3Taking the first information for communications of multiple QoSs as an example, the first information includes the first configuration information of the first operation mode and the second configuration information of the second operation mode. Among them, the first configuration information is part of the configuration information of the first operation mode. The second configuration information is part of the configuration information of the second operation mode. In other words, the configuration information included in the first information is applicable to communications of different QoSs and / or communications of different types of terminal devices, and has commonality. Therefore, the configuration information included in this first information can also be called common configuration information, or common-level configuration information, or shared configuration information, etc., without limitation. For example, the first configuration information can be the common configuration information of the first operation mode. For example, the second configuration information can be the common configuration information of the second operation mode.

[0135] The working energy consumption of the first operation mode is less than that of the second operation mode. For example, the first operation mode can be the default mode in single RRC state, and the second operation mode can be the enhanced mode in single RRC state. For relevant introductions, please refer to the foregoing content and will not be elaborated here.

[0136] 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 the first operation mode, configuration information for a common search space for different types of terminal devices and / or for different QoSs, configuration information for a wake-up signal, or configuration information for initial access, etc.

[0137] The second configuration information may include one or more of the following: configuration information for an SRB of a certain type, measurement configuration information, common CSI-RS configuration information for measurements in the second operation mode, configuration information for a common search space for different types of terminal devices and / or for different QoSs, configuration information for a wake-up signal, or configuration information for initial access, etc.

[0138] It can be 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, both the first configuration information and the second configuration information may include configuration information for a certain type of SRB, and the value of the configuration information for the certain type of SRB included in the first configuration information is different from the value of the configuration information for the certain type of SRB included in the second configuration information.

[0139] It can be understood that the first configuration information and the second configuration information may be broadcast through the first system message, or the first configuration information and the second configuration information may also be broadcast through different system messages, without limitation.

[0140] S302: The network device sends the first dedicated signaling to the first terminal device.

[0141] Correspondingly, the first terminal device receives the first dedicated signaling from the network device.

[0142] The first dedicated signaling may be, for example, RRC signaling or the like, but is not limited thereto. The first dedicated signaling may carry the 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 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 embodiments of the present application, the type of the first terminal device is the first type. For the type of the terminal device, please refer to the foregoing content and will not be elaborated here. The QoS requirement of the service of the first terminal device is the first QoS.

[0143] The second information may include the third configuration information of the first operation mode, or the second information may include the fourth configuration information of the second operation mode, or the second information may include the third configuration information of the first operation mode and the fourth configuration information of the second operation mode. Figure 3 Taking the second information being used for communication of the first QoS, and the second information including the third configuration information of the first operation mode and / or the fourth configuration information of the second operation mode as an example. 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 included in the second information is applicable to communication of the first QoS and / or applicable to communication of the first type of terminal device. Compared with the first information, the second information has specificity. Therefore, the configuration information included in the second information may also be referred to as dedicated configuration information, or UE-level configuration information, etc., without limitation. For example, the third configuration information may be dedicated configuration information of the first operation mode. For example, the fourth configuration information may be dedicated configuration information of the second operation mode.

[0144] 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) (such as precoding, resource allocation, modulation and coding scheme (MCS) table, or additional demodulation reference signal (DMRS), etc.), or configuration information of CSI-RS. etc.

[0145] 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 (such as precoding, resource allocation, MCS table, etc., or additional DMRS, etc.), or configuration information of CSI-RS.

[0146] It can be understood 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, both the third configuration information and the fourth configuration information may include the configuration information of CG, and the value of the configuration information of CG included in the third configuration information is different from the value of the configuration information of CG included in the fourth configuration information.

[0147] In one implementation, the first information may include the first configuration information or include 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 operation mode in advance. In another implementation, the first information may include the second configuration information or include 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 operation mode in advance. In yet another implementation, 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 operation mode and the configuration information of the second operation mode in advance.

[0148] Among them, the first information includes the first configuration information of the first operation mode, and the second information includes the third configuration information of the first operation mode. It can be replaced with: The first information includes partial configuration information of the first operation mode, and the second information includes other configuration information of the first operation mode; or it can also be replaced with: The first information includes partial configuration information of the first operation mode, and the second information includes the remaining configuration information of the first operation mode; or it can also be replaced with: The first information includes common configuration information of the first operation mode, and the second information includes dedicated configuration information of the first operation mode. Similarly, the first information includes the second configuration information of the second operation mode, and the second information includes the fourth configuration information of the second operation mode. It can be replaced with: The first information includes partial configuration information of the second operation mode, and the second information includes other configuration information of the second operation mode; or it can also be replaced with: The first information includes partial configuration information of the second operation mode, and the second information includes the remaining configuration information of the second operation mode; or it can also be replaced with: The first information includes common configuration information of the second operation mode, and the second information includes dedicated configuration information of the second operation mode. For the replacement description of the first information including the first configuration information of the first operation mode and the third configuration information of the second operation mode, and the second information including the third configuration information of the first operation mode and / or the fourth configuration information of the second operation mode, please refer to the foregoing content and will not be elaborated here.

[0149] Taking the first operation mode as the default mode and the second operation mode as the enhanced mode as an example, a part of the configuration information of the default mode and 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 partial configuration information of the default mode (i.e., the first configuration information) and partial 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 the communication of multiple types of terminal devices, and the second information is used for the communication of the first type of terminal device, as shown in (1) of Figure 4 ; or, the first information is used for the communication of multiple QoSs, and the second information is used for the communication of the first QoS, as shown in (2) of Figure 4 ; or, the first information is used for the communication of multiple types of terminal devices and for the communication of multiple QoSs, and the second information is used for the communication of the first type of terminal device and for the communication of the first QoS. It can be referred to the content shown in Figure 4 . Figure 4Among (1), multiple types of terminal devices include a UE of type 1, a UE of type 2, and a UE of type 3, and the terminal device of the first type is taken as the UE of type 2 for illustration. Figure 4 Among (2), multiple QoSs include QoS1, QoS2, and QoS 3, and the first QoS is taken as QoS 3 for illustration.

[0150] It can be understood 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 signaling, 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 requirement for big data services, 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 operation mode to reduce power consumption, and then be configured with the second operation mode conditionally. Another example is that the first information includes the first configuration information and the second configuration information. The network device can first send dedicated signaling 2 to the first terminal device, and the dedicated signaling 2 carries the fourth configuration information; when the third condition is met (for example, there is no transmission requirement 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 operation mode to ensure the reliability of data transmission, and then be configured with the first operation mode conditionally.

[0151] In the above first communication method, the first terminal device can obtain the configuration information of the first operation mode and / or the second operation 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 QoSs, 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 operation mode and / or the second operation mode of multiple terminal devices by storing the first information and the second information for different QoSs. Compared with the need to store the configuration information of the first operation mode and the second operation mode for each terminal device, the above embodiments of the present application can reduce the storage information of the network device, enable the network device to provide services for more terminal devices within a limited storage space, and is beneficial to improving the communication performance of the network device.

[0152] Figure 3 In the illustrated embodiment, the network device configures the first operation mode and / or the second operation mode for the first terminal device. In another possible implementation manner, the network device can also configure a signaling radio bearer (SRB) for the first terminal device, such asFigure 5 as shown

[0153] Figure 5 Exemplarily shown is a schematic flowchart of a second communication method provided by an embodiment of the present application. In this embodiment, the network device can configure the SRBs of multiple terminal devices by storing a small amount of configuration information of the SRBs, which can reduce the storage information of the network device. As Figure 5 shown, the second communication method may include the following content.

[0154] S501: The network device sends a second system message. For example, the network device may broadcast the second system message.

[0155] Correspondingly, the first terminal device receives the second system message.

[0156] In this embodiment, the network device can configure the SRB for the first terminal device in two ways, which are respectively denoted as method one (i.e., S501) and method two (i.e., S502 and S503). In other words, the network device can execute S501, or can also execute S502 and S503, Figure 5 which is shown in a dashed box.

[0157] The second system message may be, for example, an SIB, but is not limited thereto. The second system message may carry third information. The third information may be used for communication of at least one QoS (or at least one QoS list), and the third information 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 the third information 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 the third information 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. Figure 5 Taking the third information for communication of at least one QoS and the third information including configuration information of SRBs corresponding to the at least one QoS as an example. Among them, the communication of at least one QoS can be understood as the communication of at least one QoS requirement, or understood as the communication of services with at least one QoS requirement. For the description of the type of terminal device, please refer to the description of S301 and will not be elaborated here. The SRBs corresponding to at least one QoS can be understood as the SRBs applicable to the at least one QoS, or can also be understood as the SRBs meeting the at least one QoS requirement, etc. The SRBs corresponding to at least one type of terminal device can be understood as the SRBs applicable to the at least one type of terminal device, etc.

[0158] In one implementation, 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 the first terminal device receives the second system message, it may obtain the configuration information of the SRB corresponding to the first QoS. Optionally, the at least one QoS may belong to multiple QoSs, that is, the multiple QoSs include at least one QoS. For the description of the multiple QoSs, please refer to S301 and will not be elaborated here.

[0159] In one implementation, the at least one type may include a first type. For example, the type of the first terminal device is the first type. After the first terminal device receives the second system message, it may obtain the configuration information of the SRB corresponding to the terminal device of the first type. 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. For the description of the multiple types of terminal devices, please refer to S301 and will not be elaborated here.

[0160] It can be understood that a system message may carry (or bear) the configuration information of the SRBs corresponding to multiple QoSs (and / or multiple types of terminal devices), that is, the third information is used for the communication of multiple QoSs (and / or multiple types of terminal devices), and the third information includes the configuration information of the SRBs corresponding to multiple QoSs (and / or multiple types of terminal devices); or, a system message may also only carry the configuration information of the SRB corresponding to one QoS (and / or one type of terminal device), that is, the third information is used for the communication of one QoS (and / or one type of terminal device), and the third information may include the configuration information of the SRB corresponding to one QoS (and / or one type of terminal device), without limitation. A system message carries the configuration information of the SRB corresponding to one QoS (and / or one type of terminal device). In other words, the configuration information of the SRBs corresponding to different QoSs (and / or different types of terminal devices) may be carried by different system messages. In this case, the network device may send different system messages for different QoSs (and / or different types of terminal devices), that is, S501 may be executed multiple times to implement the configuration of the SRBs for different QoSs (and / or different types of terminal devices).

[0161] Among them, the statement that the third information is used for the communication of multiple QoSs may also be expressed as: the third information is used for the communication of different QoSs. The statement that the third information is used for the communication of multiple types of terminal devices may also be expressed as: the third information is used for the communication of different types of QoSs. The statement that the third information is used for the communication of multiple QoSs and for the communication of multiple types of terminal devices may also be expressed as: the third information is used for the communication of different QoSs and for the communication of different types of terminal devices.

[0162] Exemplarily, the SRB may include SRB1, or include SRB2, or include SRB1 and SRB2. Correspondingly, the configuration information of the SRB may include the configuration information of SRB1, or include the configuration information of SRB2, or include the configuration information of SRB1 and the configuration information of SRB2. In other words, the third information may include the configuration information of SRB1 corresponding to at least one QoS; or, the third information may include the configuration information of SRB2 corresponding to at least one QoS; or, the third information may include the configuration information of SRB1 corresponding to at least one QoS and the configuration information of SRB2 corresponding to at least one QoS; or, the third information may include the configuration information of SRB1 corresponding to at least one type of terminal device; or, the third information may include the configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include the configuration information of SRB1 corresponding to at least one type of terminal device and the configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include the configuration information of SRB1 corresponding to at least one QoS and the configuration information of SRB1 corresponding to at least one type of terminal device; or, the third information may include the configuration information of SRB2 corresponding to at least one QoS and the configuration information of SRB2 corresponding to at least one type of terminal device; or, the third information may include the configuration information of SRB1 corresponding to at least one QoS, the configuration information of SRB2 corresponding to at least one QoS, the configuration information of SRB1 corresponding to at least one type of terminal device, and the configuration information of SRB2 corresponding to at least one type of terminal device.

[0163] Among them, the configuration information of the SRB may include one or more of the following: SRB ID, the configuration information of the PDCP associated with the SRB, or the configuration information of the RLC bearer (for example, logical channel ID, RLC configuration information, or MAC logical channel configuration information, etc.). The configuration information of SRB2 may include one or more of the following: SRB2 ID, the configuration information of the PDCP associated with SRB2, or the configuration information of the RLC bearer (for example, logical channel ID, RLC configuration information, or MAC logical channel configuration information, etc.). For the specific configuration information of SRB1 and SRB2, reference may be made to the content in 3GPP TS 38.331, which will not be elaborated here.

[0164] In the above S501, the first terminal device can obtain the configuration information of the SRB corresponding to at least one QoS through the third information carried in the second system message. The third information is used for 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 configuration information of the SRB for each terminal device, the above embodiments of the present application can reduce the stored information of the network device, enable the network device to serve more terminal devices within a limited storage space, and is beneficial to improving the communication performance of the network device.

[0165] S502: The network device sends the third system message. For example, the network device can broadcast the third system message.

[0166] Correspondingly, the first terminal device receives the third system message.

[0167] The third system message can be, for example, SIB, but is not limited thereto. The third system message can carry the fourth information. The fourth information can be used for communication of one or more QoSs (or one or more QoS lists), or the fourth information can be used for communication of one or more types of terminal devices, or the fourth information can be used for communication of one or more QoSs and for communication of one or more types of terminal devices. For ease of understanding, the following description will be given by taking the fourth information for communication of multiple QoSs and / or multiple types of terminal devices as an example. Or it can also be expressed as: the fourth information can be used for communication of different QoSs, or the fourth information can be used for communication of different types of terminal devices, or the fourth information can be used for communication of different QoSs and for communication of different types of terminal devices. Among them, the communication of multiple QoSs can be understood as the communication of multiple QoS requirements, or understood as the communication of services with multiple QoS requirements. The communication of different QoSs can be understood as the communication of different QoS requirements, or understood as the communication of services with different QoS requirements. For the description of multiple types of terminal devices, please refer to the description of S301 and will not be elaborated here.

[0168] The fourth information can include the fifth configuration information of the SRB corresponding to multiple QoSs, or the fourth information can include the seventh configuration information of the SRB corresponding to multiple types of terminal devices, or the fourth information can include the fifth configuration information of the SRB corresponding to multiple QoSs and the seventh configuration information of the SRB corresponding to multiple types of terminal devices. Figure 5The fourth information in the middle is used for communication of multiple QoSs. Taking the fifth configuration information of the SRBs corresponding to the multiple QoSs included in the fourth information as an example for illustration. The fifth configuration information can be understood as partial configuration information of the SRBs corresponding to the multiple QoSs. The seventh configuration information can be understood as partial configuration information of the SRBs corresponding to the multiple types of terminal devices. In other words, the configuration information included in the fourth information is applicable to communication with different QoSs and / or adapted to communication with different types of terminal devices, and has commonality. Therefore, the configuration information included in the fourth information can also be referred to as common configuration information, or common-level configuration information, or shared configuration information, etc., without limitation. For example, the fifth configuration information can be the common configuration information of the SRBs corresponding to the multiple QoSs. For example, the seventh configuration information can be the common configuration information of the SRBs corresponding to the multiple types of terminal devices.

[0169] Exemplarily, the SRB can include SRB1, or include SRB2, or include SRB1 and SRB2. Correspondingly, the fifth configuration information can be understood as the common configuration information of SRB1 corresponding to the multiple QoSs, or understood as the common configuration information of SRB2 corresponding to the multiple QoSs, or understood as the common configuration information of SRB1 corresponding to the multiple QoSs and the common configuration information of SRB2 corresponding to the multiple QoSs. The seventh configuration information can be understood as the common configuration information of SRB1 corresponding to the multiple types of terminal devices, or understood as the common configuration information of SRB2 corresponding to the multiple types of terminal devices, or understood as the common configuration information of SRB1 corresponding to the multiple types of terminal devices and the common configuration information of SRB2 corresponding to the multiple types of terminal devices.

[0170] Among them, the common configuration information of SRB1 can include one or more of the following: the configuration information of the PDCP associated with SRB1, the RLC bearer configuration information associated with SRB1, the RLC configuration information associated with SRB1, or the logical channel configuration information associated with SRB1. The common configuration information of SRB2 can include one or more of the following: the configuration information of the PDCP associated with SRB2, the RLC bearer configuration information associated with SRB2, the RLC configuration information associated with SRB2, or the logical channel configuration information associated with SRB2.

[0171] S503: The network device sends the second dedicated signaling to the first terminal device.

[0172] Correspondingly, the first terminal device receives the second dedicated signaling from the network device.

[0173] The second dedicated signaling may be RRC signaling or the like, but is not limited thereto. The second dedicated signaling may carry 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 QoSs, that is, multiple QoSs include the first QoS. The first type belongs to multiple types, that is, multiple types include the first type. In the embodiments of the present application, the type of the first terminal device is the first type. For the type of the terminal device, please refer to the foregoing content and will not be elaborated herein. The QoS requirement of the service of the first terminal device is the first QoS.

[0174] The fifth information may include sixth configuration information of the SRB corresponding to the first QoS, or the fifth information may include eighth configuration information of the terminal device corresponding to the first type, or the fifth information may include sixth configuration information of the SRB corresponding to the first QoS and eighth configuration information of the terminal device corresponding to the first type. Figure 5 Taking 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 as an example. Among them, the sixth configuration information is different from the configuration information of the SRB corresponding to the first QoS included 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 included in the seventh configuration information. In other words, the configuration information included in the fifth information is applicable to communication of the first QoS and / or applicable to communication of the first type of terminal device, and has specificity. Therefore, the configuration information included in the fifth information may also be referred to as dedicated configuration information, or UE-level configuration information, etc., without limitation. For example, the sixth configuration information may be dedicated configuration information of the SRB corresponding to the first QoS. For example, the eighth configuration information may be dedicated configuration information of the SRB corresponding to the first type of terminal device.

[0175] Exemplarily, the SRB may include SRB1, or include SRB2, or include SRB1 and SRB2. Correspondingly, the sixth configuration information may be understood as dedicated configuration information of SRB1 corresponding to the first QoS, or understood as dedicated configuration information of SRB2 corresponding to the first QoS, or understood as dedicated configuration information of SRB1 corresponding to the first QoS and dedicated configuration information of SRB2 corresponding to the first QoS. The eighth configuration information may be understood as dedicated configuration information of SRB1 corresponding to the first type of terminal device, or understood as dedicated configuration information of SRB2 corresponding to the first type of terminal device, or understood as dedicated configuration information of SRB1 corresponding to the first type of terminal device and dedicated configuration information of SRB2 corresponding to the first type of terminal device.

[0176] Among them, the dedicated configuration information of SRB1 may include one or more of the following: the configuration information of the RLC bearer associated with SRB1, the logical channel identifier associated with SRB1, the RLC configuration information associated with SRB1, or the logical channel configuration information associated with SRB1. The dedicated configuration information of SRB2 may include one or more of the following: the configuration information of the RLC bearer associated with SRB2, the logical channel identifier associated with SRB2, the RLC configuration information associated with SRB2, or the logical channel configuration information associated with SRB2.

[0177] In one implementation, 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 implementation, 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 implementation, 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.

[0178] It should be noted that the fifth configuration information and the seventh configuration information may be different or may be the same, without limitation. The sixth configuration information and the eighth configuration information may be different or may be the same, without limitation.

[0179] In S502 and S503 above, 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 QoSs, and the fifth information is used for communication of the first QoS, which means that the network device can configure the SRBs corresponding to different QoSs of multiple terminal devices through the fourth information and the fifth information for different QoSs. Compared with the need to store the configuration information of the SRB for each terminal device, the above embodiments of the present application can reduce the stored information of the network device, enable the network device to provide services for more terminal devices within a limited storage space, and is beneficial to improving the communication performance of the network device.

[0180] In one possible implementation, the network device may release (or delete) the context of the first terminal device, thereby reducing its own stored information.

[0181] Figure 6A schematic flowchart of a third communication method provided by an embodiment of the present application is exemplarily shown. In this embodiment, the network device may release the context of the first terminal device, and the first terminal device releases the context. As Figure 6 shown, the third communication method may include the following.

[0182] S601: The network device releases the context of the first terminal device.

[0183] In this embodiment, the network device may release (or delete) the context of the first terminal device. For example, the network device may actively release the context of the first terminal device. In one implementation, when the fourth condition is met, the network device may release the context of the first terminal device. 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 operation mode, etc. It can be understood that the embodiments of the present application do not limit the triggering conditions for the network device to release the context of the first terminal device. In addition, the embodiments of the present application do not limit the specific implementation process for the network device to select which or which terminal devices' contexts to release. For example, if the first terminal device is in the RRC inactive state, the network device may release the context of the first terminal device. Another example is that if the first terminal device is in the first operation mode, the network device may release the context of the first terminal device.

[0184] Exemplarily, the context of the first terminal device may include configuration information of the first operation mode, or include configuration information of the second operation mode, or include configuration information of the first operation mode and the second operation mode. The power consumption of the first operation mode is less than that of the second operation mode. For the relevant descriptions of the first operation mode and the second operation mode, please refer to Figure 3 the relevant content in the shown embodiments, and will not be repeated here.

[0185] Exemplarily, the context of the first terminal device may include at least one of the following: air interface configuration information, security-related information (such as keys, or count values, etc.), mapping of QoS flows and DRBs, C-RNTI, original cell identity (ID), or terminal device capability information, etc. For specific references, please refer to the relevant content in 3GPP TS 38.331, and will not be repeated here.

[0186] S602: The network device sends the sixth information to the first terminal device.

[0187] Correspondingly, the first terminal device receives the sixth information.

[0188] The sixth piece of information can be used to indicate the release of context. For example, the sixth piece of information can be used to indicate that the first terminal device releases context. Alternatively, the sixth piece of information can be used to indicate entering the initial mode. For example, the sixth piece of information can be used to indicate that the first terminal device enters 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 context during the process of establishing a connection with the network side.

[0189] In one implementation, the sixth piece of information can be carried by the first paging message. That is, the network device sends the first paging message, and the first paging message carries the sixth piece of information. For example, the network device can broadcast the first paging message. Correspondingly, the first terminal device can receive the first paging message. Optionally, the sixth piece of information can be a paging cause, and the value of the paging cause can be used to indicate the release of context, or the value of the paging cause can be used to indicate entering the initial mode. In this implementation, the sixth piece of information can indicate that one terminal device (i.e., the first terminal device) releases context; or, the sixth piece of information can also indicate that multiple terminal devices release context. Or rather, the sixth piece of information can indicate that one terminal device (i.e., the first terminal device) enters the initial mode; or, the sixth piece of information can also indicate that multiple terminal devices enter the initial mode. For example, the network device can release the context of multiple terminal devices and send the first paging message. The multiple terminal devices include the first terminal device. Optionally, 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 the default mode), or the multiple terminal devices are all in the RRC inactive state, without limitation.

[0190] In another implementation, the sixth piece of information can be carried by a first short message. That is, the network device sends the first short message, and the first short message carries the sixth piece of information. For example, the network device can broadcast the first short message. Correspondingly, the first terminal device can receive the first short message. In this implementation, the sixth piece of information can indicate that a terminal device (i.e., the first terminal device) releases the context; alternatively, the sixth piece of information can also indicate that multiple terminal devices release the context. Or rather, the sixth piece of information can indicate that a terminal device (i.e., the first terminal device) enters the initial mode; alternatively, the sixth piece of information can also indicate that multiple terminal devices enter the initial mode. For example, the network device can release the contexts 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 (e.g., all in the default mode), or the multiple terminal devices are all in the RRC inactive state, without limitation.

[0191] Exemplarily, the sixth piece of information can be the first field in the first short message. The value of the first field can include a first value, or include a second value, or include both the first value and the second value. The first value can be used to indicate that a terminal device in the first operating mode releases the context (or the first value is used to indicate that a terminal device in the first operating mode enters the initial mode). The second value can be used to indicate that a terminal device in the RRC inactive state releases the context. Optionally, the first value can be 0 and the second value can be 1; or, the first value can be 1 and the second value can be 0; or, the value of the first field includes the first value and does not include the second value, and the value of the first value can be 1 or 0; or, the value of the first field includes the second value and does not include the first value, and the value of the second value can be 1 or 0. The embodiments of the present application do not limit the specific implementation forms of the first value and the second value. The first field can be, for example, a UE context release indication field, as shown in Table 1. It can be understood that the embodiments of the present application do not limit the number of bits occupied by the first field and the naming of the first field. For the other fields in the short message shown in Table 1 except the UE context release indication field, please refer to the description of short messages in the relevant 3GPP protocols, which will not be elaborated here.

[0192] Table 1

[0193]

[0194] In another implementation, the sixth piece of 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 piece of information. Correspondingly, the first terminal device may receive the first wake-up signal. For example, the sixth piece of information may occupy 1 bit in the first wake-up signal, and is used to indicate whether the first terminal device releases the context or is used to indicate whether the first terminal device enters the initial mode. The embodiments of the present application do not limit the specific implementation form of the sixth piece of 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 piece of information to the first terminal device through a low-power module.

[0195] In yet another implementation, the sixth piece of information may be carried by downlink control information (DCI). That is, the network device may send DCI to the first terminal device, and the DCI carries the sixth piece of information; correspondingly, the first terminal device may receive the DCI. For example, the sixth piece of information may occupy 1 bit in the DCI, and is used to indicate whether the first terminal device releases the context or is used to indicate whether the first terminal device enters the initial mode. The embodiments of the present application do not limit the specific implementation form of the sixth piece of 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.

[0196] S603: The first terminal device releases the context according to the sixth piece of information.

[0197] After the first terminal device receives the sixth piece of information, it can release (or delete) the context according to the sixth piece of information. For example, the first terminal device enters the initial mode according to the sixth piece of information and releases the context. Optionally, if the first terminal device subsequently receives a paging message or there is uplink data in the first terminal device, the first terminal device can re-initiate a random access procedure to obtain the context. For example, the first terminal device can re-obtain 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.

[0198] In Figure 6 In the embodiment shown, 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 piece of information of the network device. Compared with the solution where 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 network resource utilization rate can be improved.

[0199] In Figure 6 In the embodiment shown, the network device can actively release the context of the first terminal device. In another possible implementation, the network device can also release the context of the first terminal device by negotiating with the first terminal device, as Figure 7 shown.

[0200] Figure 7 Exemplarily shown is another schematic flowchart of the third communication method provided by the embodiments of the present application. In this embodiment, the network device releases the context of the first terminal device in response to the auxiliary information of the first terminal device, and the first terminal device releases the context. As Figure 7 shown, the third communication method may include the following content.

[0201] S701: The network device sends the seventh piece of information to the first terminal device.

[0202] Correspondingly, the first terminal device receives the seventh piece of information from the network device.

[0203] The seventh piece of 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, information about the predicted service (such as 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 retaining the context, the auxiliary information can be used to determine not to release the context; or, if the indication information is used to indicate not retaining the context, the auxiliary information can be used to determine to release the context.

[0204] In one implementation, the seventh piece of 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 piece of 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 piece of information can be a paging cause, and the value of the paging cause can be used to request auxiliary information, or rather, the value of the paging cause can be used to trigger the first terminal device to send auxiliary information. In this implementation, the seventh piece of information can trigger one terminal device (i.e., the first terminal device) to send auxiliary information; or, the seventh piece of 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 operation mode (such as all in the default mode), without limitation.

[0205] In another implementation, the seventh piece of 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 piece of 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 implementation, the seventh piece of information can trigger one terminal device (i.e., the first terminal device) to send auxiliary information; or, the seventh piece of 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 operation mode (such as all in the default mode), without limitation.

[0206] Exemplarily, the seventh information may be the second field in the second short message. The value taken by 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 be, for example, the field for triggering the UE to send auxiliary information, as shown in Table 2. It can be understood that the embodiments of the present application do not limit the number of bits occupied by the second field and the naming of the second field. For the other fields in the short message shown in Table 2 except the field for triggering the UE to send auxiliary information, please refer to the description of short messages in the relevant 3GPP protocols, which will not be elaborated here.

[0207] Table 2

[0208]

[0209] In another implementation manner, the seventh information may be carried by the second wake-up signal. That is, the network device may send the second wake-up signal to the first terminal device, and the second wake-up signal carries the seventh information. Correspondingly, 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 and is used to indicate the first terminal device to send auxiliary information. The embodiments of the present application do not limit the specific implementation form of the seventh information. Optionally, the second wake-up signal may be an 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 operating mode, or include configuration information of the second operating mode, or include configuration information of the first operating mode and the second operating mode. For the context, please refer to the relevant description of S601 and will not be elaborated here.

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

[0212] Correspondingly, 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 according to 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, an example is given where the network device determines 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 according to the auxiliary information, and the auxiliary information is used to determine the context release.

[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. For the content of the fourth condition, please refer to S601 and will not be elaborated here. In other words, the network device may determine whether to release the context of the first terminal device according to the auxiliary information from the first terminal device and its own relevant situation. For example, the indication information in the auxiliary information indicates to retain the context of the first terminal device, but the storage information of the network device reaches the set threshold, then the network device may determine to release the context of the first terminal device according to the auxiliary information and its own relevant situation.

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

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

[0219] The sixth information may be used to indicate context release, that is, the sixth information is used to indicate that the first terminal device releases the context. Alternatively, the sixth information may be used to indicate entering the initial mode, that is, the sixth information is used to indicate that the first terminal device enters the initial mode. The first terminal device in the initial mode needs to establish a connection with the network side. During the process of the first terminal device establishing a connection with the network side, the first terminal device may obtain the context. In this embodiment, the sixth information may be a confirmation information, or the sixth information may be carried by DCI, without limitation.

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

[0221] After receiving the sixth information, the first terminal device may 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 receives a paging message or there is uplink data in the first terminal device later, the first terminal device may re-initiate the random access process to obtain the context. For example, the first terminal device may re-obtain 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 Figure 7 In the illustrated embodiment, the network device can release the context of the first terminal device according to the auxiliary information of the first terminal device, which can reduce the stored information of the network device and reduce the impact on the services of the first terminal device. The first terminal device releases the context in response to the sixth information of the network device, which can reduce the stored information of the first terminal device.

[0223] In a possible implementation, the network device can release the context of the first terminal device to reduce its own stored information; afterwards, the first terminal device can re-obtain the context, as Figure 8 shown. For example, the network device releases the context of the first terminal device, and the first terminal device does not release the context. The first terminal device can re-obtain the context.

[0224] Figure 8 Exemplarily shown is a schematic flow diagram of the fourth communication method provided by the embodiments of the present application. In this embodiment, the network device releases the context of the first terminal device, and the first terminal device re-obtains the context. As Figure 8 shown, 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 can release (or delete) the context of the first terminal device. For the specific implementation process, please refer to the relevant content of S601 and will not be elaborated here.

[0227] In this embodiment, the first terminal device can re-obtain the context in three ways, which are respectively denoted as way 1 (i.e., S802 and S803), way 2 (i.e., S804 and S805), and way 3 (i.e., S806 and S807). In other words, the first terminal device can execute S802 and S803, or can also execute S804 and S805, or can also execute S806 and S807, Figure 8 which is represented by a dotted box.

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

[0229] Correspondingly, the first terminal device receives the 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 context, or the eighth information can be used to indicate that the context stored by the first terminal device is invalid. For example, the eighth information can be a paging cause, and the value of the paging cause can be used to instruct the first terminal device to obtain context, or the value of the paging cause can be used to indicate that the context stored by the first terminal device is invalid. Exemplarily, when 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 context. It can be understood that the embodiments of the present application do not limit the triggering conditions for the network device to send the third paging message.

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

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

[0233] The ninth information is used to request context. Exemplarily, after receiving the third paging message, the first terminal device can 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 the tenth information to the network device.

[0235] The tenth information can be used to request a switch from the first operating mode to the second operating mode; or, the tenth information can be used to request a switch from the second operating mode to the first operating mode. For the relevant descriptions of the first operating mode and the second operating mode, please refer to the foregoing content and will not be elaborated here. Exemplarily, when uplink data arrives, the first terminal device can send the tenth information to the network device. For example, when 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 a switch from the first operating mode to the second operating mode. Another example is that when 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 a switch from the second operating mode to the first operating mode. It can be understood that the embodiments of the present application do 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 information may be received successfully, that is, the network device receives the tenth information from the first terminal device; or, the tenth information may also be received unsuccessfully. For example, when the network device releases the context of the first terminal device and the first terminal device does not release the context, the network device may receive the tenth information unsuccessfully. Figure 8 Taking the case where the tenth information is received unsuccessfully as an example is shown below.Figure 8 In the Chinese version, the failure of receiving the tenth information is indicated by "×".

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

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

[0239] The ninth information is used to request context. In one implementation, the first condition may be: the response message of the tenth information is used to indicate that the first terminal device acquires 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, when 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 from the first terminal device, the network device may send the response message of the tenth information to the first terminal device. In one example, the response message of the tenth information may be a handover 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 handover 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). Correspondingly, 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 implementation, the first condition may be: the retransmission count of the tenth information is equal to (or reaches) the first maximum retransmission count. For example, when the network device releases the context of the first terminal device and the first terminal device does not release the context, the network device may fail to receive the tenth information. When the retransmission count of the tenth information is equal to the first maximum retransmission count, the first terminal device may send the ninth information to the network device. Herein, the first maximum retransmission count may be configured by the network device or may also be predefined, without limitation.

[0241] In another implementation, the first condition may be that the timer corresponding to the tenth information expires. For example, after the first terminal device sends the tenth information, it may start the timer corresponding to the tenth information. During the operation of the timer corresponding to the tenth information, the first terminal device may wait for the response message of the tenth information. For example, if the network device releases the context of the first terminal device and 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 the response message of the tenth information during the operation of the timer corresponding to the tenth information, it may turn off the timer corresponding to the tenth information. If the timer corresponding to the tenth information expires, it means that the first terminal device does not receive the response message of 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. Wherein, the duration of the timer corresponding to the tenth information may be configured by the network device or may also be predefined, without limitation.

[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 that the retransmission count of the tenth information is equal to the first maximum retransmission count and the timer corresponding to the tenth information expires. Another example is that the first condition may be that 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 expires. Another example is that the first condition may be that the retransmission count of the tenth information is equal to the first maximum retransmission count and the response message of the tenth information is used to instruct the first terminal device to obtain the context. Another example is that the first condition may be that the response message of the tenth information is used to instruct the first terminal device to obtain the context, the retransmission count of the tenth information is equal to the first maximum retransmission count, and the timer corresponding to the tenth information expires. For the specific implementation process, please refer to the foregoing content and will not be elaborated here.

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

[0244] Exemplarily, the first terminal device may send uplink data to the network device. In this embodiment, the reception of the uplink data fails. For example, if the network device releases the context of the first terminal device and the first terminal device does not release the context, the network device cannot receive the uplink data. Figure 8 In the figure, "×" is used to indicate that the reception of the uplink data fails. 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 operation mode, while the network device releases the configuration information of the first operation mode, resulting in the failure of the uplink data transmission. Another example is that 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 operation mode, while the network device releases the configuration information of the second operation mode, resulting in the failure of the uplink data transmission.

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

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

[0247] The ninth information is used to request context. In one implementation, 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, 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. Among them, the second maximum number of retransmissions may be configured by the network device or may also be predefined, without limitation.

[0248] In another implementation, the first condition may be: the timer corresponding to the uplink data expires. For example, after the first terminal device sends the uplink data, it may start the timer corresponding to the uplink data. During the operation of the timer corresponding to the uplink data, the first terminal device may wait for the response message of the uplink data. For example, the network device releases the context of the first terminal device, the first terminal device does not release the context, and the network device cannot receive the uplink data, resulting in the expiration of the timer corresponding to the uplink data, and the first terminal device sends the ninth information to the network device. Among them, the duration of the timer corresponding to the uplink data may be configured by the network device or may also be predefined, without limitation.

[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 expires. For the specific implementation process, please refer to the foregoing content and will not be elaborated here.

[0250] In the fourth communication method, the network device releases the context of the first terminal device to reduce its own stored information. Further, the first terminal device may re-acquire the context in response to the third paging message of the network device or when the first condition or the fifth condition is satisfied. In this way, even if the network device has released the context of the first terminal device and the first terminal device has not released the context, the first terminal device can re-acquire the context in multiple ways, and the implementation method is flexible.

[0251] It should be noted that Figure 3 the first communication method shown Figure 5 the second communication method shown Figure 6 or Figure 7 the third communication direction shown, and Figure 8 the fourth communication method shown 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 initial access of the first terminal device is completed, a connection is established with the core network based on the configuration information of the SRB. During this period, the network device can configure the first operation mode and / or the second operation 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 operation mode and the second operation mode for the first terminal device according to the first communication method. After that, the network device and the first terminal device can release the configuration information of the first operation mode and the configuration information of the second operation 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 operation mode and the second operation mode for the first terminal device according to the first communication method. After that, the network device releases the configuration information of the first operation mode and the configuration information of the second operation mode, and the first terminal device can re-acquire the configuration information of the first operation mode and the configuration information of the second operation 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 initial access of the first terminal device is completed, a connection is established with the core network based on the configuration information of the SRB. During this period, the network device can configure the first operation mode and the second operation mode for the first terminal device according to the first communication method; after that, the network device and the first terminal device can release the configuration information of the first operation mode, the configuration information of the second operation mode and the configuration information of the SRB according to the third communication method.

[0256] In yet 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 initial access of the first terminal device is completed, a connection is established with the core network based on the configuration information of the SRB. During this period, the network device can configure the first operation mode and the second operation mode for the first terminal device according to the first communication method; after that, the network device can release the context of the first terminal device, and the first terminal device can re-acquire the context according to the fourth communication method.

[0257] It can be understood that the remaining combination cases are similar. For the sake of brevity, they are not listed one by one here.

[0258] It should be noted that when the above various communication methods are used in combination, the embodiments of the present application do not limit the execution order of the various communication methods. For example, the network device may configure the first operation mode and the second operation mode for the first terminal device according to the first communication method; afterwards, the network device and the first terminal device may release the configuration information of the first operation mode and the configuration information of the second operation mode according to the third communication method. Alternatively, the network device and the first terminal device may release the configuration information of the first operation mode and the configuration information of the second operation mode according to the third communication method; afterwards, the network device may reconfigure the first operation mode and the second operation 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 executed by the communication device (for example, the first terminal device or the network device) may be implemented by different functional entities constituting the terminal device. The communication device (for example, the first terminal device or the network device) may include a hardware structure and / or a software module, and implement the above various functions in the form of a hardware structure, a software module, or a combination of a hardware structure and a software module. Whether a certain function among the above various functions is executed in the form of a hardware structure, a software module, or a combination of a hardware structure and a software module depends on the specific application and design constraint conditions of the technical solution.

[0260] The communication device used to implement the above method in the embodiments of the present application is introduced below with reference to the accompanying drawings. Therefore, the content in the above can be used in subsequent embodiments, and the repeated content will not be elaborated.

[0261] Figure 9 The structural schematic diagram of a communication device 900 is exemplarily shown. The communication device 900 may implement the functions or steps implemented by the first terminal device or the network device in the above various method embodiments. For example, the communication device 900 may be a network device or a component in a network device (such as a DU, etc.), or a terminal device or a component in a terminal device.

[0262] In one implementation, the communication device 900 may include a processing module 901 and a transceiver module 902. Among them, the processing module 901 may be used for data processing, such as executing the above various method embodiments. The processing module 901 may also be referred to as a processing unit, etc. 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, or a communication module, or a transceiver unit, etc.

[0263] It should be noted that the communication device 900 may include a processing module 901 but not include a transceiver module 902. Alternatively, the communication device 900 may include a transceiver module 902 but not include a processing module 901. Specifically, it depends on whether the above-mentioned solution executed by the communication device 900 includes processing actions and transceiver actions.

[0264] Optionally, the communication device 900 may further include a storage module, Figure 9 which is not shown in the figure. The storage module may be used to store instructions and / or data, and the processing module 901 may read the instructions and / or data in the storage module to enable the communication device 900 to implement the foregoing method embodiments.

[0265] Optionally, the transceiver module 902 may include a sending module and a receiving module. The sending module is used to perform the sending operation in the foregoing method embodiments. The receiving module is used to perform the receiving operation in the foregoing method embodiments.

[0266] It should be noted that the communication device 900 may include a sending module but not include a receiving module. Alternatively, the communication device 900 may include a receiving module but not include a sending module. Specifically, it depends on whether the above-mentioned solution executed by the communication device 900 includes sending actions and receiving actions.

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

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

[0269] As an example, the communication device 900 may perform the following: The transceiver module 902 may 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 QoSs; and, receive a first dedicated signaling from a network device, the first dedicated signaling carries second information, and the second information is used for communication of a first QoS, and the first QoS belongs to multiple QoSs; wherein, the first information includes first configuration information of a first operation mode and second configuration information of a second operation mode, the second information includes third configuration information of the first operation mode and / or fourth configuration information of the second operation mode, the working energy consumption of the first operation mode is less than the working energy consumption of the second operation 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] Another example, the communication device 900 may perform the following: The transceiver module 902 may be used to receive a second system message, which may carry third information for communication of at least one QoS.
