In some embodiments, the terminal device may be deployed on water, such as on a ship. In some embodiments, the terminal device may be deployed in the air, such as on an airplane, balloon, or satellite.

[0033] In addition to terminal devices, the communication system may also include one or more network devices. In this embodiment, the network device can be a device for communicating with the terminal device; this network device may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. In this embodiment, the network device may refer to an access network (RAN) node (or device) that connects the terminal device to the wireless network. Access network equipment can broadly encompass various names listed below, or be interchangeable with them, such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, secondary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. Base stations can be macro base stations, micro base stations, relay nodes, donor nodes, or similar entities, or combinations thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, or a device that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device performing base station functions in future communication systems. Base stations can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0034] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0035] In some deployments, the network device in this application embodiment may refer to a CU or a DU, or the network device may include both a CU and a DU. The gNB may also include an AAU.

[0036] By way of example and not limitation, in the embodiments of this application, the network device may have mobility characteristics; for example, the network device may be a mobile device. In some embodiments of this application, the network device may be satellite-based or space-based, that is, the network device is installed on a satellite or flying equipment. In some embodiments of this application, the network device may also be a base station installed in locations such as land or water.

[0037] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0038] For example, Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0039] Figure 1 illustrates an exemplary network device and two terminal devices. In some embodiments of this application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit this aspect.

[0040] In some embodiments of this application, the wireless communication system shown in FIG1 may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but this application does not limit this.

[0041] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Taking the communication system 100 shown in FIG1 as an example, the communication devices may include network devices 110 and terminal devices 120 with communication functions. Network devices 110 and terminal devices 120 can be the specific devices described above, which will not be repeated here. The communication devices may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities, which are not limited in this application embodiment.

[0042] In communication systems, DRBs are typically established by access network devices upon request from core network devices, primarily for transmitting application layer service data. In related technologies, all DRBs configured via RRC messages are active by default to support application layer data transmission. However, with the introduction of new data transmission services into communication systems (such as model training dataset transmission tasks and measurement result collection tasks), some issues regarding DRB management methods (i.e., DRB activation or deactivation behavior) in related technologies need to be addressed.

[0043] For example, the starting and ending points of these newly introduced data transmission services are very flexible. For instance, they could be from the access stratum (AS) of the terminal device to the access network device, from the AS of the terminal device to the core network device, or from the non-access stratum (NAS) of the terminal device to the core network device. At the same time, the data transmission process corresponding to these data transmission services may involve discontinuous scenarios. For example, for measurement result collection tasks, due to the memory limitations of the terminal device, the terminal device might transmit data by collecting data for a period of time, then transmitting the data, then stopping data transmission, and then collecting data again for a period of time. If the DRB established by the default network device is always active, it will lead to low utilization efficiency of the DRB (data is sent for a period of time, and not sent for a period of time). Furthermore, frequent reconfiguration of the DRB via RRC messages incurs significant overhead and latency.

[0044] For example, relying on network devices to manage DRBs is not very reasonable in related technologies. The reason is that in scenarios where terminal devices send data to network devices, the terminal devices are more aware of whether data is being sent, and the network devices' blind decisions may not meet the actual needs of the terminal devices at that time.

[0045] Therefore, with the introduction of new data transmission services into communication systems, how to efficiently manage DRBs is a problem that needs to be solved in the embodiments of this application.

[0046] To address the aforementioned issues, this application embodiment determines whether to activate or deactivate the DRB based on the request information (first information) from the terminal device. This approach fully considers the service transmission requirements of the terminal device, is more user-friendly for the terminal device, makes the method of requesting to activate or deactivate the DRB more reasonable, and helps to improve the utilization efficiency of the DRB.

[0047] The embodiments of this application will be described in detail below.

[0048] Figure 2 is a flowchart illustrating the communication method provided in an embodiment of this application. Referring to Figure 2, in step S210, the terminal device sends first information to the access network device. Correspondingly, the access network device receives the first information sent by the terminal device.

[0049] The first piece of information is used to determine whether the terminal device needs to activate or deactivate the DRB.

[0050] For example, the first information can be used to request activation of at least one or at least one set of DRBs configured via the second information. Alternatively, the first information can be used to request deactivation of at least one or at least one set of DRBs configured via the second information. Furthermore, the first information can be used simultaneously to request activation and deactivation of at least one or at least one set of DRBs configured via the second information.

[0051] A DRB bearer can be established through configuration of several protocol layers. For example, a DRB-related configuration may include the Packet Data Convergence Protocol (PDCP) protocol layer configuration. Furthermore, if the PDCP protocol layer and the Radio Link Control (RLC) protocol layer are merged into a new protocol layer (referred to as the first protocol layer), then a DRB-related configuration may include the first protocol layer configuration.

[0052] An activated DRB can be described as being in an active state. An active DRB can be defined as follows: it can be used to transmit data. Specifically, this means that the PDCP protocol layer involved in the DRB can process and deliver data normally, or that the Service Data Adaptation Protocol (SDAP), PDCP, and RLC protocol layers involved in the DRB can process and deliver data normally. If the PDCP and RLC protocol layers are merged into a first protocol layer, it means that the first protocol layer involved in the DRB can process and deliver data normally, or that the SDAP and first protocol layers involved in the DRB can process and deliver data normally.

[0053] A deactivated DRB can be described as being in a deactivated state. A deactivated DRB can be defined as follows: Data transmission is not permitted using this DRB. Specifically, this means that the PDCP protocol layer involved with the DRB cannot process and deliver data normally, or that the SDAP, PDCP, and RLC protocol layers involved with the DRB cannot process and deliver data. If the PDCP and RLC protocol layers are merged into a first protocol layer, it means that the first protocol layer involved with the DRB cannot process and deliver data normally, or that the SDAP and first protocol layers involved with the DRB cannot process and deliver data normally.

[0054] In some embodiments, the access network device can be any one of gNB, centralized unit (CU), distributed unit (DU), centralized unit-control plane (CU-CP), and centralized unit-user plane (CU-UP).

[0055] As previously mentioned, the DRB is configured via second information. This second information can be sent by the access network device. For example, referring to Figure 3, in step S310, the terminal device receives the second information sent by the access network device; correspondingly, the access network device sends the second information to the terminal device. The second information is used to configure at least one or at least one set of DRBs.

[0056] The second information may include one or more of bearer identification information and bearer group identification information. The bearer identification information can be the identification information corresponding to a DRB. This bearer identification information can be a logical ID. The bearer group identification information can be the identification information corresponding to a group of DRBs. This bearer group identification information can be one or more of a group identifier, task type identifier, or session identifier.

[0057] For example, the second information may include bearer identification information corresponding to at least one data radio bearer. Alternatively, the second information may include at least one set of bearer identification information and / or bearer group identification information corresponding to data radio bearers. Exemplarily, the second information may include at least one set of bearer identification information corresponding to data radio bearers, or it may include at least one set of bearer identification information and bearer group identification information corresponding to data radio bearers, or it may include at least one set of bearer group identification information corresponding to data radio bearers.

[0058] There are multiple ways to implement the first information. The following describes four implementation methods in detail.

[0059] Implementation Method 1

[0060] The first information may include a first bit string, which is associated with one or more DRBs configured in the second information, or in other words, the first bit string corresponds to one or more DRBs configured in the second information. For example, assuming the first target bit is any bit in the first bit string, the first target bit can be associated with one DRB configured in the second information. Of course, the first target bit can also be associated with multiple DRBs configured in the second information, and this application embodiment does not specifically limit this.

[0061] The association between the bits in the first bit string and the DRB can be called a mapping relationship (first mapping relationship). In some embodiments, the first mapping relationship can be used to indicate the correspondence between the position of the bits in the first bit string and the order in which the bearer identification information corresponding to the DRB appears in the second information.

[0062] The order in which the bearer identifier information corresponding to a DRB appears in the second information can also be understood as the positional relationship (or logical order) of the DRBs configured in the second information. For example, the DRB corresponding to the first bearer identifier information appearing in the second information is called the first DRB, the DRB corresponding to the second bearer identifier information appearing in the second information is called the second DRB, and so on. The DRB corresponding to the Nth bearer identifier information appearing in the second information is called the Nth DRB. N is an integer greater than or equal to 1. Therefore, the first mapping relationship mentioned above can also be used to indicate the correspondence between the position of a bit (or bit) in the first bit string and the position of a DRB (or DRB) configured in the second information.

[0063] In the first mapping relationship, there are multiple ways to correspond the positions of bits in the first bit string to the positions of DRBs. For example, the first bit in the first bit string can correspond to the first DRB configured through the second information, and the second bit in the first bit string can correspond to the second DRB configured through the second information. That is, the Mth bit in the first bit string can correspond to the Mth DRB configured through the second information. M is an integer greater than or equal to 1. As another example, the last bit in the first bit string can correspond to the first DRB configured through the second information, and the second-to-last bit in the first bit string can correspond to the second DRB configured through the second information. That is, the Pth bit from the end in the first bit string can correspond to the Pth DRB configured through the second information. P is an integer greater than or equal to 1.

[0064] Furthermore, the values ​​of the bits in the first bit string can be used to indicate whether the DRB associated with that bit is activated (or deactivated).

[0065] Taking the first target bit in the first bit string as an example, when the value of the first target bit is a first value (such as '1'), the first target bit is used to instruct the terminal device to request activation of a DRB associated with the first target bit. Alternatively, when the value of the first target bit is a second value (such as '0'), the first target bit is used to instruct the terminal device to request deactivation or non-activation of a DRB associated with the first target bit.

[0066] To facilitate understanding, a more concrete example is given below to illustrate this implementation method in detail.

[0067] Suppose the access network device configures five DRBs (Drag Routes) to the terminal device via the second information, denoted as DRB1, DRB2, DRB3, DRB4, and DRB5. Scenario 1: Assuming all five DRBs are currently deactivated or inactive, after a period of time, the terminal device decides to request activation of DRB1 and DRB3 via the first information. In this case, the first bit string included in the first information requires 5 bits and has a value of '10100'. Based on the value of the first bit string, the access network device confirms that the terminal device is requesting activation of DRB1 and DRB3. Scenario 2: Assuming DRB4 and DRB5 are already activated, after a period of time, the terminal device decides to request activation of DRB1 and DRB3 via the first information, while simultaneously requesting deactivation of DRB4 and DRB5. In this case, the first bit string included in the first information requires 5 bits and has a value of '10100'. Based on the value of the first bit string, the access network device confirms that the terminal device is requesting activation of DRB1 and DRB3, while simultaneously deactivating DRB4 and DRB5.

[0068] Based on implementation method one, the terminal device can request management (request activation / request deactivation) of one or more DRBs configured through the second information. The advantages of this implementation method are: it helps save signaling overhead; and it is suitable for batch requests to manage one or more DRBs, resulting in high request efficiency.

[0069] Implementation Method Two

[0070] The first information may include a second bit string, which is associated with one or more DRBs configured in the second information, or in other words, the second bit string corresponds to one or more DRBs configured in the second information. For example, assuming the second target bit is any bit in the second bit string, the second target bit can be associated with one set of DRBs configured in the second information. Of course, the second target bit can also be associated with multiple sets of DRBs configured in the second information, and this application embodiment does not specifically limit this.

[0071] A group of DRBs may include one or more DRBs. Grouping multiple DRBs may include: each DRB configured via second information is associated with a bearer group identifier. This bearer group identifier may be a group identifier, task type identifier, or session identifier, used to assist the terminal device in identifying which DRBs belong to the same group or serve the same data transmission task. Further, one or more DRBs associated with the same bearer group identifier may be grouped into a single group of DRBs (e.g., all DRBs serving the same data transmission task belong to the same group). In this grouping method, for example, the second information may include bearer identifier information corresponding to one or more DRBs and bearer group identifier information corresponding to one or more groups of DRBs.

[0072] The association between bits in the second bit string and a set of DRBs can be called a mapping relationship (second mapping relationship). In some embodiments, the second mapping relationship can be used to indicate the correspondence between the position of bits in the second bit string and the order in which the bearer group identification information corresponding to the DRB appears in the second information, or the second mapping relationship can be used to indicate the correspondence between the position of bits in the second bit string and the order in which the bearer identification information corresponding to the DRB appears in the second information.

[0073] The order in which the bearer group identifier information corresponding to a group of DRBs appears in the second information can also be understood as the positional relationship (or logical order) of each group of DRBs configured in the second information. For example, the group of DRBs corresponding to the first bearer group identifier information appearing in the second information is called the first group of DRBs, the group of DRBs corresponding to the second bearer group identifier information appearing in the second information is called the second group of DRBs, that is, the group of DRBs corresponding to the Nth bearer group identifier information appearing in the second information is called the Nth group of DRBs. N is an integer greater than or equal to 1. Therefore, the second mapping relationship mentioned above can also be used to indicate the correspondence between the position of a bit (or bit) in the second bit string and the position (or DRB) of each group of DRBs configured in the second information.

[0074] In the second mapping relationship, there are multiple ways to correspond the positions of bits in the second bit string to the positions of DRBs. For example, the first bit in the second bit string can correspond to the first group of DRBs configured through the second information, and the second bit in the second bit string can correspond to the second group of DRBs configured through the second information. That is, the Mth bit in the second bit string can correspond to the Mth group of DRBs configured through the second information. M is an integer greater than or equal to 1. As another example, the last bit in the second bit string can correspond to the first group of DRBs configured through the second information, and the second-to-last bit in the second bit string can correspond to the second group of DRBs configured through the second information. That is, the Pth bit from the end in the second bit string can correspond to the Pth group of DRBs configured through the second information. P is an integer greater than or equal to 1.

[0075] Furthermore, the values ​​of the bits in the second bit string can be used to indicate whether to activate (or deactivate) a set of DRBs associated with that bit.

[0076] Taking the second target bit in the second bit string as an example, when the value of the second target bit is the third value (such as '1'), the second target bit is used to instruct the terminal device to request activation of the set of DRBs associated with the second target bit. Alternatively, when the value of the second target bit is the fourth value (such as '0'), the second target bit is used to instruct the terminal device to request deactivation or non-activation of the set of DRBs associated with the second target bit.

[0077] To facilitate understanding, a more concrete example is given below to illustrate this implementation method in detail.

[0078] Suppose that five DRBs are configured through the second information, denoted as DRB1, DRB2, DRB3, DRB4, and DRB5. DRB1 and DRB2 form the first group of DRBs, DRB3 and DRB4 form the second group, and DRB5 forms the third group. Scenario 1: Assuming all three groups of DRBs are in a deactivated or inactive state, after a period of time, the terminal device decides to request activation of the first group of DRBs through the first information. In this case, the second bit string included in the first information needs to occupy 3 bits and have a value of '100'. Based on the value of the second bit string, the access network device confirms that the terminal device is requesting activation of the first group of DRBs. Scenario 2: Assuming the second group of DRBs is already activated, after a period of time, the terminal device decides to request activation of the first group of DRBs and simultaneously request deactivation of the second group of DRBs through the first information. In this case, the second bit string included in the first information needs to occupy 3 bits and have a value of '100'. Based on the value of the second bit string, the access network device confirms that the terminal device is requesting activation of the first group of DRBs and simultaneously requesting deactivation of the second group of DRBs.

[0079] Based on implementation method two, the terminal device can request management (request activation / request deactivation) of one or more DRBs configured through the second information. The advantages of this implementation method are: it helps save signaling overhead; and it is suitable for batch request management of one or more DRBs, resulting in high request efficiency.

[0080] Implementation Method 3

[0081] The first information may directly include the bearer identification information corresponding to the DRB. For example, the first information may include the bearer identification information corresponding to at least one DRB that has been requested to be activated. Alternatively, the first information may include the bearer identification information corresponding to at least one DRB that has been requested to be deactivated. Or, the first information may include the bearer identification information corresponding to at least one DRB that has been requested to be activated, and also include the bearer identification information corresponding to at least one DRB that has been requested to be deactivated.

[0082] Based on implementation method three, the terminal device can request management (request activation / request deactivation) of one or more DRBs configured through the second information. The advantage of this implementation method is that it is suitable for batch requesting management of one or more DRBs and has high request efficiency.

[0083] Implementation Method 4

[0084] The first information can directly include the bearer group identifier information corresponding to each DRB. For example, the first information can include the bearer group identifier information corresponding to at least one DRB that is requested to be activated. Alternatively, the first information can include the bearer group identifier information corresponding to at least one DRB that is requested to be deactivated. The bearer group identifier information can be one or more of a group identifier, a task type identifier, or a session identifier. A detailed explanation of the bearer group identifier information can be found in Implementation Method 2, and will not be repeated here.

[0085] Based on implementation method four, the terminal device can request management (request activation / request deactivation) of one or more DRBs configured through the second information. The advantages of this implementation method are: management at the DRB group level is more efficient; at the same time, this implementation method is suitable for batch request management of one or more DRBs, with high request efficiency.

[0086] The above text details four implementation methods for the first information. For any of these four implementation methods, in some embodiments, the first information may further include second and / or third indication information. The second indication information can be used to indicate the reason why its associated DRB is activated. The granularity of the DRB indicated by the second indication information can be the DRB granularity or the DRB group granularity; that is, the second indication information can be used to indicate the reason why a DRB or a group of DRBs is activated by the terminal device. For example, the definition of the second indication information may include one or more of the following: the terminal device records enough data; the terminal device's memory for recording data is full; the terminal device has little remaining memory for recording data; the online training scenario requires timely uploading of the dataset; and other data services on the terminal device are not busy.

[0087] The third indication information can be used to indicate the reason for deactivating a DRB associated with it. The granularity of the DRB indicated by the third indication information can be either the DRB granularity or the DRB group granularity. That is, the third indication information can be used to indicate the reason why a DRB or a group of DRBs is instructed to be deactivated by the terminal device. For example, the definition of the third indication information may include one or more of the following: insufficient data recorded by the terminal device, large remaining memory space for data recording by the terminal device, or busy other data services on the terminal device.

[0088] It should be understood that the second and third instruction information described above can be implemented in combination or separately. That is to say, the first information may include the second instruction information, or the first information may also include the third instruction information, or the first information may also include both the second and third instruction information.

[0089] By using the second and / or third instruction information in the first information, the network device can clearly understand the specific reason why the terminal device requests DRB activation or deactivation, thereby helping the network device to confirm the urgency of the request and the response strategy, which is conducive to the network device performing refined management actions in response to the terminal device's request.

[0090] The previous section detailed four ways to implement the first information. The following section details how the first information is carried.

[0091] In some embodiments, the first information may be carried in any one of an RRC message, a media access control control element (MAC CE), or uplink control information (UCI). If the first information is carried via a MAC CE, then the first information also includes MAC sub-header information. The MAC sub-header information contains a first logical channel identifier (ID), and the first logical channel ID is associated with one or more of requesting DRB function activation and requesting DRB function deactivation. In some implementations, the MAC CE carrying the first logical channel identifier is used for DRB function activation, in which case the first logical channel ID is considered to be associated with requesting DRB function activation; in other implementations, the MAC CE carrying the first logical channel identifier is used for DRB function deactivation, in which case the first logical channel ID is considered to be associated with requesting DRB function deactivation; in still other implementations, the MAC CE carrying the first logical channel identifier can be used for both DRB function activation and DRB deactivation, in which case the first logical channel ID is considered to be associated with requesting DRB function deactivation.

[0092] The advantages of MAC CE (Message Message overlay) are: compared to UCI (User-defined communication), reliable transmission of the first message via MAC CE is guaranteed; and compared to RRC (Redirect Receipt Code) messages, the latency of the first message via MAC CE is shorter.

[0093] The advantage of the RRC message carrying method is that it has a larger information carrying capacity and is more in line with the logic of the RRC layer to make radio bearer activation (or deactivation) decisions.

[0094] It should be noted that before the terminal device triggers the request contained in the first information, the terminal device's behavior may include the following two:

[0095] In one behavioral pattern, the terminal device is not allowed to autonomously activate and / or deactivate any one or a group of DRBs before receiving explicit management instructions (such as DRB activation or deactivation instructions sent by the network device) from the access network device. In other words, the terminal device cannot autonomously make management (activation or deactivation) decisions regarding DRBs. This approach helps ensure that the resource status understanding between the terminal device and the access network device remains consistent, effectively avoiding potential problems caused by differences in their understanding of resource status, thereby improving the overall stability and reliability of the communication system.

[0096] Alternatively, in another approach, the terminal device can make autonomous decisions based on its own resource management needs. That is, before sending the first information, the terminal device can activate or deactivate one or a group of corresponding DRBs according to its own needs. The purpose of still sending the first information to the access network device is to achieve consistency between the terminal device and the access network device in their understanding of the resource status, and to avoid resource scheduling errors caused by inconsistencies in understanding between the access network device and the terminal device.

[0097] In some embodiments, the terminal device can decide when to send the first information based on its own implementation, which makes the implementation of the terminal device the most flexible.

[0098] Alternatively, the terminal device may send the first information after certain conditions are triggered. For example, an event occurrence mechanism can be introduced to allow the terminal device to send the first information after a specific event is triggered. In some embodiments, if the first event is satisfied (also referred to as when the first event is satisfied or in response to the first event being satisfied), the terminal device sends the first information to the access network device. Here, the first information is used to request activation of at least one or at least one set of DRBs configured through the second information.

[0099] The first event can be any of multiple events. These multiple events can be divided into two types based on whether or not the terminal device's power consumption is considered. The first events of these two types will be described in detail below.

[0100] The first event of the first type: The memory occupied by the data to be reported corresponding to at least one data transmission task is greater than the first threshold; the number of data samples contained in the data to be reported corresponding to at least one data transmission task is greater than the second threshold; the memory occupied by the data to be reported corresponding to at least one data transmission task reaches the memory limit; the difference between the memory occupied by the data to be reported corresponding to at least one data transmission task and the first threshold is less than or equal to the third threshold (i.e., the memory occupied by the data to be reported corresponding to at least one data transmission task is expected to soon exceed the first threshold); the difference between the number of data samples contained in the data to be reported corresponding to at least one data transmission task and the second threshold is less than or equal to the fourth threshold (i.e., the difference between the number of data samples in the data to be reported corresponding to at least one data transmission task and the second threshold is less than or equal to the fourth threshold). The number of data samples contained in the data to be reported corresponding to the transmission task is expected to soon exceed the second threshold; the difference between the memory occupied by the data to be reported corresponding to at least one data transmission task and the memory limit is less than or equal to the fifth threshold (i.e., the memory occupied by the data to be reported corresponding to at least one data transmission task is expected to soon reach the memory limit); the memory occupied by the data to be reported corresponding to at least one data transmission task is expected to exceed the first threshold after the first time period; the number of data samples contained in the data to be reported corresponding to at least one data transmission task is expected to exceed the second threshold after the first time period; the memory occupied by the data to be reported corresponding to at least one data transmission task is expected to reach the memory limit after the first time period.

[0101] The first event of the second type: At least one data transmission task corresponds to a data to be reported whose memory usage exceeds a first threshold, and the terminal device's current battery level is greater than or equal to a sixth threshold (i.e., the terminal device has sufficient battery power); at least one data transmission task corresponds to a data to be reported whose data sample count exceeds a second threshold, and the terminal device's current battery level is greater than or equal to a sixth threshold; at least one data transmission task corresponds to a data to be reported whose memory usage reaches the memory limit, and the terminal device's current battery level is greater than or equal to a sixth threshold; at least one data transmission task corresponds to a data to be reported whose memory usage differs from the first threshold by less than or equal to a third threshold, and the terminal device's current battery level is greater than or equal to a sixth threshold; at least one data transmission task corresponds to a data to be reported whose data sample count exceeds the second threshold by less than or equal to a third threshold. The difference is less than or equal to the fourth threshold, and the current battery level of the terminal device is greater than or equal to the sixth threshold; the difference between the memory occupied by the data to be reported corresponding to at least one data transmission task and the memory limit is less than or equal to the fifth threshold, and the current battery level of the terminal device is greater than or equal to the sixth threshold; it is expected that the memory occupied by the data to be reported corresponding to at least one data transmission task will be greater than the first threshold after the first duration, and the current battery level of the terminal device is greater than or equal to the sixth threshold; it is expected that the number of data samples included in the data to be reported corresponding to at least one data transmission task will be greater than the second threshold after the first duration, and the current battery level of the terminal device is greater than or equal to the sixth threshold; it is expected that the memory occupied by the data to be reported corresponding to at least one data transmission task will reach the memory limit after the first duration, and the current battery level of the terminal device is greater than or equal to the sixth threshold.

[0102] Since the first event of the second type takes into account the power factor of the terminal device, it helps to avoid the situation where the terminal device is interrupted due to power depletion.

[0103] As described above regarding the two types of first events, each type includes three judgment criteria: the current amount of data to be reported has reached a certain standard; the current amount of data to be reported is expected to reach a certain standard soon; and the current amount of data to be reported is expected to reach a certain standard after a certain time interval. The "current amount of data to be reported has reached a certain standard" criterion simplifies the implementation on the terminal device. The "current amount of data to be reported is expected to reach a certain standard soon" criterion provides some flexibility for the terminal device implementation, helping to avoid scenarios where subsequent data is missed due to the activation request (sending the first information) being triggered after memory reaches its limit. The "current amount of data to be reported is expected to reach a certain standard after a certain time interval" criterion allows the network device to clearly understand the urgency of the activation request (first information) and also reserves a certain time interval for the terminal device, helping to avoid scenarios where subsequent data is missed due to memory reaching its limit.

[0104] In some embodiments, the data transmission task corresponding to the first event may include one or more of the following: a data transmission task for measurement data, a data transmission task for the model training dataset, a data transmission task for intermediate data of the two-end model training, and a data transmission task for model data.

[0105] The first threshold mentioned above can be determined through protocol predefinition or through configuration information sent by the access network device; the second threshold can be determined through protocol predefinition or through configuration information sent by the access network device; the first duration can be determined through protocol predefinition or through configuration information sent by the access network device. Similarly, the third to sixth thresholds mentioned above can also be determined through protocol predefinition or through configuration information sent by the access network device.

[0106] Introducing a first event during the process of the terminal device triggering the sending of the first information ensures that the terminal device will only initiate the request to activate the DRB by sending the first information when the accumulated data amount is sufficient. This avoids the terminal device frequently requesting to activate the DRB, which helps to improve the utilization efficiency of the DRB and also avoids the situation where frequent requests to activate the DRB cause large air interface overhead.

[0107] Alternatively, if the second event is satisfied (also referred to as when the second event is satisfied or in response to the second event being satisfied), then the terminal device sends the first information to the access network device. This first information is used to request the deactivation of at least one or at least one set of DRBs configured via the second information.

[0108] The second event can be any of several events. These events will be described in detail below.

[0109] Second event: The memory occupied by the data to be reported for at least one data transmission task is less than or equal to the seventh threshold; the number of data samples contained in the data to be reported for at least one data transmission task is less than or equal to the eighth threshold; the difference between the memory occupied by the data to be reported for at least one data transmission task and the seventh threshold is less than or equal to the ninth threshold (i.e., the memory occupied by the data to be reported for at least one data transmission task is expected to soon be less than or equal to the seventh threshold); the difference between the number of data samples contained in the data to be reported for at least one data transmission task and the eighth threshold is less than or equal to the tenth threshold (i.e., the number of data samples contained in the data to be reported for at least one data transmission task is expected to soon be less than or equal to the eighth threshold); the memory occupied by the data to be reported for at least one data transmission task is expected to be less than or equal to the seventh threshold after the second duration; the number of data samples contained in the data to be reported for at least one data transmission task is expected to be less than or equal to the eighth threshold after the second duration; the current battery level of the terminal device is less than or equal to the eleventh threshold (i.e., the current battery level of the terminal device is insufficient).

[0110] As described above regarding the second event, it encompasses four judgment criteria: the current amount of data to be reported is already below a certain standard; the current amount of data to be reported is expected to soon fall below a certain standard; the current amount of data to be reported is expected to fall below a certain standard after a second set of time; and the terminal device assesses its own current battery level. The criterion of the current amount of data to be reported being below a certain standard simplifies implementation for the terminal device. The expectation that the current amount of data to be reported will soon fall below a certain standard provides some flexibility for the terminal device, helping to avoid scenarios where DRB remains active even without data transmission. The expectation that the current amount of data to be reported will fall below a certain standard after a second set of time allows the network device to clearly define the urgency of the deactivation request (first information) and also provides the terminal device with a certain amount of time, helping to avoid scenarios where DRB remains active even without data transmission. Finally, the terminal device assessing its own current battery level helps to avoid scenarios where data transmission is interrupted due to battery depletion.

[0111] In some embodiments, the data transmission task corresponding to the second event may include one or more of the following: a data transmission task for measurement data, a data transmission task for the model training dataset, a data transmission task for intermediate data of the two-end model training, and a data transmission task for model data.

[0112] The value of the seventh threshold mentioned above can be determined through protocol predefinition or through configuration information sent by the access network device; the value of the eighth threshold can be determined through protocol predefinition or through configuration information sent by the access network device; the value of the second duration can be determined through protocol predefinition or through configuration information sent by the access network device. Of course, the ninth to eleventh thresholds mentioned above can also be determined through protocol predefinition or through configuration information sent by the access network device.

[0113] Introducing a second event during the process of the terminal device triggering the sending of the first information ensures that the terminal device will only initiate a request to deactivate the DRB by sending the first information when the amount of remaining unreported data is sufficiently small. This avoids the terminal device frequently requesting to deactivate the DRB, which helps improve the utilization efficiency of the DRB and also avoids the situation where frequent requests to deactivate the DRB cause large air interface overhead.

[0114] In this embodiment, both the first event and the second event can be introduced into an event occurrence mechanism to trigger the terminal device to send the first information. In this case, if only the first event is satisfied, the terminal device can request to activate the DRB; if only the second event is satisfied, the terminal device can request to deactivate the DRB; if both the first event and the second event are satisfied, the terminal device can request to activate some DRBs associated with data transmission tasks, and at the same time request to deactivate other DRBs associated with data transmission tasks.

[0115] Alternatively, the first or second event can be introduced separately to trigger the terminal device to send the first information.

[0116] To avoid frequent requests from terminal devices to activate and / or deactivate the DRB (sending first information) and improve DRB utilization efficiency, this application embodiment can introduce a first timer for the terminal device. During the operation of the first timer (i.e., before the first timer expires), the terminal device will not trigger the sending of the first information. The timing duration of the first timer can be configured by the access network device. For example, referring to Figure 4, in step S410, the terminal device receives third information sent by the access network device; correspondingly, the access network device sends third information to the terminal device. This third information is used to indicate the timing duration of the first timer.

[0117] Furthermore, in some embodiments, the first timer can be started when the terminal device triggers the sending of the first information; or, the first timer can be started when the terminal device confirms that the first information has been successfully received by the access network device. For example, the terminal device can confirm that the first information has been successfully received based on feedback information (such as an ACK message) successfully received by the data sent by the access network device.

[0118] In some scenarios, terminal devices may not be allowed to activate and / or deactivate the DRB. Therefore, certain conditions can be used to determine whether the terminal device is allowed to trigger the transmission of the first message.

[0119] For example, referring to Figure 5, in step S510, the terminal device receives first indication information sent by the access network device; correspondingly, the access network device sends first indication information to the terminal device. The value of the first indication information is used to indicate whether the access network device allows the terminal device to trigger the sending of first information. The first indication information can be configured to be sent to the terminal device through system broadcast messages or dedicated signaling.

[0120] For example, when the value of the first indication information is the fifth value (e.g., the value is '1'), it means that the access network device allows the terminal device to trigger the sending of the first information; when the value of the first indication information is the sixth value (e.g., the value is '0'), it means that the access network device does not allow the terminal device to trigger the sending of the first information.

[0121] For example, a terminal device can determine whether it is possible to trigger the sending of the first information based on the indication of the first capability information.

[0122] For example, when the value of the first capability information is the seventh value (e.g., the value is '1'), it means that the terminal device can (has the ability) trigger the sending of the first information; when the value of the first capability information is the eighth value (e.g., the value is '0'), it means that the terminal device cannot (does not have the ability) trigger the sending of the first information.

[0123] For example, the terminal device can determine whether to trigger the sending of the first information based on the value of the first indication information in Figure 5 and the indication of the first capability information. In this approach, the terminal device can trigger the sending of the first information only if the value of the first indication information indicates that the terminal device is allowed to send the first information, and the value of the first capability information also indicates that the terminal device is allowed to send the first information; otherwise, if either of the above two conditions indicates that the terminal device is not allowed to send the first information, then the terminal device will not be able to trigger the sending of the first information.

[0124] This application embodiment determines whether to activate or deactivate the DRB based on the request information (first information) from the terminal device. This approach fully considers the service transmission requirements of the terminal device, is more user-friendly for the terminal device, makes the method of requesting to activate or deactivate the DRB more reasonable, and helps to improve the utilization efficiency of the DRB.

[0125] The method embodiments of this application have been described in detail above with reference to Figures 1 to 5. The apparatus embodiments of this application will be described in detail below with reference to Figures 6 to 8. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0126] Figure 6 is a schematic diagram of a terminal device according to an embodiment of this application. The terminal device 600 shown in Figure 6 includes: a transmitting unit 610.
