[0031] 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.

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.

[0032] Base stations can be fixed or mobile.

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.

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.

[0037] 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.

[0038] 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.

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.

[0040] Data wireless bearer resource establishment

[0041] In related technologies, within communication systems defined by the 3rd Generation Partnership Project (3GPP), data radio bearers are generally established by access network equipment in response to requests from core network equipment. Data radio bearers are primarily used for application layer service transmission. All data radio bearers configured via radio resource control (RRC) messages are active by default.

[0042] Activation and deactivation states of data radio bearers

[0043] The data radio bearer can be active. Alternatively, the data radio bearer can be deactivated.

[0044] When a data radio bearer is active, it can be used to transmit data. That is, the Packet Data Convergence Protocol (PDCP) layer involved in an active data radio bearer can process and deliver data normally. Alternatively, the Service Data Adaptation Protocol (SDAP), PDCP, and Radio Link Control (RLC) layers involved in an active data radio bearer can process and deliver data normally. If the PDCP and RLC layers are merged into a first protocol layer, then the first protocol layer involved in an active data radio bearer can process and deliver data normally; or, the SDAP and first protocol layers involved in an active data radio bearer can process and deliver data normally. Unless otherwise specified, this description of the active state of the data radio bearer applies throughout this application and will not be repeated hereafter.

[0045] When a data radio bearer is in a deactivated state, data transmission is not permitted using that data radio bearer. In other words, the PDCP protocol layer involved in a deactivated data radio bearer cannot process and deliver data normally. Alternatively, the SDAP, PDCP, and RLC protocol layers involved in a deactivated data radio bearer cannot process and deliver data. If the PDCP and RLC protocol layers are merged into a first protocol layer, then the first protocol layer involved in a deactivated data radio bearer cannot process and deliver data normally, or in other words, the SDAP and first protocol layers involved in a deactivated data radio bearer cannot process and deliver data normally. Unless otherwise specified, this description of the deactivated state of a data radio bearer applies throughout this application and will not be repeated hereafter.

[0046] For newly generated data transmission services within the communication system (e.g., model iteration training tasks, model training dataset transmission tasks, measurement result collection tasks, etc.), the start and end points of these data transmission services are highly flexible. These data transmission services can originate from the terminal device's access stratum (AS) to the access network device, from the terminal device's access stratum to the core network device, from the terminal device's non-access stratum (NAS) to the core network device, or from the access network device to the terminal device's access stratum, etc. Furthermore, the data transmission process corresponding to these data transmission services may involve discontinuous scenarios. For example, for model iteration training tasks, the terminal device may periodically receive intermediate model training data sent by the network device. If the data radio bearer established by the network device is always active by default, it may lead to low utilization efficiency of the established data radio bearer (data is sent intermittently). Moreover, frequently reconfiguring the data radio bearer via RRC messages incurs significant overhead and latency. Therefore, how to efficiently manage the data radio bearer after introducing new service requirements is a problem that needs to be solved.

[0047] To address the aforementioned problems, embodiments of this application provide a communication method. Using this method, one or more data radio bearers can be configured based on first information sent by an access network device, thereby facilitating efficient management of the data radio bearers.

[0048] The communication method provided in the embodiments of this application will be described in detail below with reference to Figure 2.

[0049] Figure 2 is a schematic flowchart of a communication method provided in an embodiment of this application. The method in Figure 2 is described from the perspective of a terminal device. The terminal device in Figure 2 can be the terminal device 120 mentioned above. This terminal device can be used to communicate with an access network device. This terminal device can be, for example, a UE.

[0050] Referring to Figure 2, the communication method provided in this application embodiment may include the following step S210.

[0051] In step S210, the terminal device receives the first information sent by the access network device; correspondingly, the access network device sends the first information to the terminal device.

[0052] The first information can be used to configure one or more data radio bearers. The first information can be carried via an RRC message. The first information may include bearer identification information corresponding to the one or more data radio bearers. In embodiments of this application, "bearer identification information" may include or be replaced with: bearer identifier.

[0053] The bearer identifier corresponding to a data radio bearer can be a logical identifier (ID). Generally, a data radio bearer can be established through configuration of several protocol layers. Configuration related to a data radio bearer may include PDCP protocol layer configuration. If the PDCP protocol layer and the RLC protocol layer are merged into a new protocol layer (hereinafter referred to as the first protocol layer), then configuration related to a data radio bearer may include the first protocol layer configuration. In some cases, configuration related to a data radio bearer may also include SDAP protocol layer configuration.

[0054] As can be seen from the description of step S210, in this embodiment of the application, one or more data radio bearers are configured based on the first information sent by the access network device in order to efficiently manage the data radio bearers.

[0055] In this embodiment, the management of the data radio bearer can include two phases. The first phase of management can be understood as controlling the activation state of the data radio bearer during the configuration process. This first phase of management can be implemented based on the first information in step S210. The second phase of management can be understood as controlling the activation state of the data radio bearer after the configuration process.

[0056] For the first stage, embodiments of this application provide three implementation methods for controlling the activation state of the data radio bearer. For the second stage, embodiments of this application provide four implementation methods for controlling the activation state of the data radio bearer.

[0057] The following sections will provide a detailed introduction to the three implementation methods for the first stage and the four implementation methods for the second stage.

[0058] Implementation method 1 for the first stage

[0059] In the first implementation method of the first phase, the terminal device can determine the initial activation state of one or more data radio bearers configured based on the first information in a predefined manner.

[0060] In this implementation, the protocol can specify the initial activation state of one or more data radio bearers configured through the first information. In the embodiments of this application, "initial activation state of the data radio bearer" can also be referred to as the initial state of the data radio bearer. The initial activation state of the data radio bearer can be an active state. Alternatively, the initial activation state of the data radio bearer can also be a deactivated state.

[0061] In some embodiments, the protocol may stipulate that the initial state of one or more data radio bearers configured through the first information is a deactivated state. That is, after successfully receiving the first information, the terminal device may not immediately activate and use the one or more data radio bearers configured based on the first information. The terminal device can subsequently activate the corresponding data radio bearer based on signaling or a timer, and then use the activated data radio bearer to perform data transmission tasks. This approach minimizes the signaling overhead for configuration. Furthermore, it allows sufficient preparation time for data transmission by the terminal device, improving the utilization efficiency of the data radio bearers.

[0062] In other embodiments, the protocol may stipulate that the initial state of one or more data radio bearers configured through the first information is an active state. That is, after successfully receiving the first information, the terminal device can immediately activate and use one or more data radio bearers configured based on the first information. This approach minimizes the signaling overhead for configuration. Furthermore, this approach simplifies the implementation of the terminal device.

[0063] Implementation Method Two for the First Stage

[0064] In the second implementation method of the first stage, the activation state of the data wireless bearer can be controlled by introducing first indication information.

[0065] In this implementation, the first information in step S210 may further include first indication information. The terminal device can determine the activation state of one or more data radio bearers configured based on the value of the first indication information.

[0066] In some embodiments, the first indication information can be configured at a granular level. That is, one or more data radio bearers configured based on the first information can be constrained by the same first indication information. This approach saves configuration overhead and is simple to implement.

[0067] In other embodiments, the first indication information can be configured at the granularity of the data radio bearer. That is, different data radio bearers can be constrained by their respective associated first indication information. This approach is more flexible and fully considers the differences in data services transmitted by different data radio bearers.

[0068] In some other embodiments, the first indication information can be configured at the granularity of data radio bearer groups. These data radio bearer groups can include one or more data radio bearers. That is, data radio bearers in different groups can be constrained by their respective associated first indication information. This approach is more flexible and fully considers the differences in data services transmitted by data radio bearers in different groups.

[0069] As mentioned above, the terminal device can determine the activation status of one or more data radio bearers configured based on the value of the first indication information. For example, if the value of the first indication information is a first value, the terminal device can be instructed to activate one or more data radio bearers associated with the first indication information. Alternatively, if the value of the first indication information is a second value, the terminal device can be instructed not to activate one or more data radio bearers associated with the first indication information.

[0070] The following example illustrates how to determine the activation status of one or more data radio bearers configured based on the value of the first indication information.

[0071] As a concrete example, the first indication information is configured according to the granularity of the first information. If the value of the first indication information is a first value (e.g., a value of '1'), the terminal device activates all data radio bearers configured based on the first information. If the value of the first indication information is a second value (e.g., a value of '0'), the terminal device does not activate all data radio bearers configured based on the first information.

[0072] As another concrete example, the first indication information is configured at the granularity of the data radio bearer. If the value of the first indication information is a first value (e.g., a value of '1'), the terminal device activates a data radio bearer associated with the first indication information. If the value of the first indication information is a second value (e.g., a value of '0'), the terminal device does not activate a data radio bearer associated with the first indication information.

[0073] As another concrete example, the first indication information is configured at the granularity of data radio bearer groups. If the value of the first indication information is a first value (e.g., a value of '1'), the terminal device activates a group of data radio bearers associated with the first indication information. If the value of the first indication information is a second value (e.g., a value of '0'), the terminal device does not activate a group of data radio bearers associated with the first indication information.

[0074] In the second implementation method of the first stage, the activation state of one or more data radio bearers configured based on the first information is controlled by introducing first indication information, thereby enhancing the flexibility of the activation method of the data radio bearer.

[0075] Implementation Method 3 of Phase 1

[0076] In the third implementation method of the first phase, the activation of the data wireless bearer can be controlled by introducing a first timer.

[0077] In this implementation, the first information in step S210 may further include second indication information. The initial activation state of one or more data radio bearers configured based on the first information can be a deactivation state.

[0078] The second indication information here can be used to indicate the timing duration of the first timer. The first timer here can be used to control the activation of one or more data radio bearers configured based on the first information.

[0079] In some embodiments, the first timer can be configured at the granularity of the first information. In this case, one or more data radio bearers configured based on the first information can be constrained by the same first timer. This approach saves configuration overhead and is simple to implement.

[0080] In other embodiments, the first timer can be configured at the granularity of the data radio bearer. In this case, different data radio bearers can be constrained by their respective associated first timers. This approach is more flexible and fully considers the differences in data services transmitted by different data radio bearers.

[0081] In some other embodiments, the first timer can be configured at the granularity of data radio bearer groups. In this case, data radio bearers in different groups can be constrained by their respective associated first timers. This approach is more flexible and fully considers the differences in data services transmitted by data radio bearers in different groups.

[0082] As mentioned above, the first timer can be used to control the activation of one or more data radio bearers configured based on the first information. The activation of one or more data radio bearers configured based on the first information can be controlled based on whether the first timer times out. If the first timer times out, the terminal device activates one or more data radio bearers associated with the first timer.

[0083] The following example illustrates how a first timer can be used to control the activation of one or more data radio bearers configured based on first information.

[0084] As a concrete example, the first timer is configured with granularity according to the first information. If the first timer times out, the terminal device activates all data radio bearers configured based on the first information.

[0085] As another concrete example, the first timer is configured at the granularity of the data radio bearer. If the first timer times out, the terminal device activates a data radio bearer associated with that first timer.

[0086] As another concrete example, the first timer is configured at the granularity of data radio bearer groups. If the first timer times out, the terminal device activates the group of data radio bearers associated with that first timer.

[0087] The first timer mentioned above can be activated under certain conditions. In some embodiments, the first timer can be activated upon confirmation by the terminal device that it has received the second instruction information.

[0088] In the third implementation method of the first phase, a first timer is introduced to control the activation state of one or more data radio bearers configured based on the first information. Introducing the first timer enables delayed activation of the data radio bearers, making the activation method more aligned with data transmission service requirements.

[0089] As can be seen from the above introduction of the three implementation methods for the first stage, for data radio bearers configured based on the first information (such as information carried by RRC messages), their initial activation state can be indicated while configuring the corresponding data radio bearer according to actual needs. This can be indicated through explicit indication information (such as the first indication information) or through a timer.

[0090] In the first phase, the control of the activation state of the data radio bearer is achieved through the first information. In the second phase, the control of the activation state of the data radio bearer is achieved through the second information mentioned below.

[0091] The method provided in this application embodiment may further include: a terminal device receiving second information sent by an access network device; correspondingly, the access network device sending the second information to the terminal device.

[0092] In some embodiments, the second information may be used to activate at least one or at least one set of data radio bearers configured based on the first information.

[0093] In other embodiments, the second information may be used to deactivate at least one or at least one set of data radio bearers configured based on the first information.

[0094] In some other embodiments, the second information can be used to activate at least one or at least one set of data radio bearers configured based on the first information, and can be used to deactivate at least one or at least one set of data radio bearers configured based on the first information.

[0095] The second piece of information can be carried in the medium access control element (MAC CE) or downlink control information (DCI). Carrying the second piece of information in the MAC CE ensures reliable transmission. Carrying it in the DCI results in shorter latency.

[0096] When the second information is carried in the MAC CE, the second information may also include medium access control (MAC) subheading information. This MAC subheading information may contain the first logical channel ID.

[0097] In some embodiments, the first logical channel ID may be associated with the activation of the data radio bearer function.

[0098] In other embodiments, the first logical channel ID may be associated with the deactivation of the data radio bearer function.

[0099] In some other embodiments, the first logical channel ID may be associated with activating the data radio bearer function and deactivating the data radio bearer function.

[0100] There are various ways to implement the control of the activation state of the data radio bearer (i.e., management of the data radio bearer) through the second information. This application provides four possible implementation methods. The following describes these four possible implementation methods in detail.

[0101] Implementation method 1 for the second stage

[0102] In the second phase of implementation method one, one or more data radio bearers can be managed based on the first bit string.

[0103] In this implementation, the second information may include a first bit string. The first target bit contained in the first bit string may be associated with a data radio bearer configured based on the first information. Here, the first target bit can be understood as any one of the bits contained in the first bit string.

[0104] A first target bit can be associated with a data radio bearer based on a first mapping relationship. In this first mapping relationship, the position of the first target bit in the first bit string can correspond to the order in which the bearer identification information corresponding to that data radio bearer appears in the first information. For example, the first target bits contained in the first bit string can be associated one-to-one with the data radio bearers configured based on the first information in a sequential order.

[0105] As a concrete example, the first bit in the first bit string is associated with the first data radio bearer configured based on the first information, the second bit in the first bit string is associated with the second data radio bearer configured based on the first information, and so on.

[0106] As another concrete example, the penultimate bit of the first bit string is associated with the first data radio bearer configured based on the first information, the penultimate bit of the first bit string is associated with the second data radio bearer configured based on the first information, and so on.

[0107] The logical order of each data radio bearer can be determined by the order in which its corresponding bearer identifier appears in the first information. For example, the data radio bearer corresponding to the first data radio bearer identifier appearing in the first information can be called the first data radio bearer, the data radio bearer corresponding to the second data radio bearer identifier appearing in the first information can be called the second data radio bearer, and so on.

[0108] When managing data radio bearers based on a first bit string, the data radio bearer can be managed based on the value of the first target bit contained in the first bit string. For example, if the value of the first target bit contained in the first bit string is a third value, the terminal device can be instructed to activate a data radio bearer associated with the first target bit. As another example, if the value of the first target bit contained in the first bit string is a fourth value, the terminal device can be instructed to deactivate or not activate a data radio bearer associated with the first target bit.

[0109] The following example illustrates how to manage data wireless bearers based on the first bit string.

[0110] In the two examples below, five data radio bearers are configured using the first information. These five data radio bearers are represented as data radio bearer 1, data radio bearer 2, data radio bearer 3, data radio bearer 4, and data radio bearer 5, respectively.

[0111] As a concrete example, suppose the access network device does not instruct the terminal device to activate any of the five data radio bearers mentioned above during the first phase. After a period of time, the access network device decides to activate data radio bearer 1 and data radio bearer 3 via second information. The second information includes a first bit string occupying 5 bits, and the value of the first bit string is '10100'. Based on the value of the first bit string, the terminal device determines to activate only data radio bearer 1 and data radio bearer 3.

[0112] As another concrete example, suppose the access network device has instructed the terminal device to activate data radio bearer 4 and data radio bearer 5 in the first phase. After a period of time, the access network device decides to activate data radio bearer 1 and data radio bearer 3, and deactivate data radio bearer 4 and data radio bearer 5 via second information. The second information includes a first bit string occupying 5 bits, and the value of the first bit string is '10100'. Based on the value of the first bit string, the terminal device confirms the activation of data radio bearer 1 and data radio bearer 3, and confirms the deactivation of data radio bearer 4 and data radio bearer 5.

[0113] In the first implementation of the second phase, by introducing a first bit string, one or more data radio bearers configured based on the first information can be managed (activated and / or deactivated). The first implementation of the second phase can save signaling overhead, is suitable for batch management of one or more data radio bearers, and has high management efficiency.

[0114] Implementation Method Two for the Second Stage

[0115] In the second implementation method of the second phase, one or more sets of data radio bearers can be managed based on the second bit string.

[0116] In this implementation, the second information may include a second bit string. The second target bit contained in the second bit string can be associated with a set of data radio bearers configured based on the first information. Here, the second target bit can be understood as any one of the bits contained in the second bit string.

[0117] Each data radio bearer configured based on the first information can be associated with any of the following: group identifier information, task type identifier information, and session identifier information. The group identifier information, task type identifier information, and session identifier information can all be used to assist the terminal device in confirming which data radio bearers belong to the same group of data radio bearers or serve the same data transmission task. It can be considered that all data radio bearers serving the same data transmission task belong to the same group of data radio bearers. For example, the first information includes bearer identifier information corresponding to one or more data radio bearers, and the group identifier information, task type identifier information, or session identifier information associated with the corresponding data radio bearer. The terminal device can determine which data radio bearers in one or more data radio bearers configured based on the first information belong to the same group based on the group identifier information, task type identifier information, or session identifier information included in the first information. This application describes the embodiments using group identifier information as an example. In some embodiments, the group identifier information can also be replaced with task type identifier information or session identifier information, and this application does not limit this.

[0118] The second target bit can be associated with a group of data radio bearers based on a second mapping relationship. In this second mapping relationship, the position of the second target bit in the second bit string can correspond to the order in which the bearer group identification information corresponding to that group of data radio bearers appears in the first information. For example, the second target bit contained in the second bit string can be associated one-to-one with one or more groups of data radio bearers configured based on the first information in a sequential order.

[0119] As a concrete example, the first bit in the second bit string is associated with the first set of data radio bearers configured based on the first information, the second bit in the second bit string is associated with the second set of data radio bearers configured based on the first information, and so on.

[0120] As another concrete example, the penultimate bit of the second bit string is associated with the first set of data radio bearers configured based on the first information, the penultimate bit of the second bit string is associated with the second set of data radio bearers configured based on the first information, and so on.

[0121] The logical order of each group of data radio bearers can be determined by the order in which the group identifier, task type identifier, or session identifier appears in the first information. For example, the group of data radio bearers corresponding to the first group identifier, task type identifier, or session identifier that appears in the first information can be called the first group of data radio bearers, the group of data radio bearers corresponding to the second group identifier, task type identifier, or session identifier that appears in the first information can be called the second group of data radio bearers, and so on.

[0122] When managing data radio bearers based on a second bit string, the data radio bearer can be managed based on the value of the second target bit contained in the second bit string. For example, if the value of the second target bit contained in the second bit string is the fifth value, the terminal device can be instructed to activate a set of data radio bearers associated with the second target bit. As another example, if the value of the second target bit contained in the second bit string is the sixth value, the terminal device can be instructed to deactivate or not activate a set of data radio bearers associated with the second target bit.

[0123] The following example illustrates how to manage data wireless bearers based on the second bit string.

[0124] In the two examples below, five data radio bearers are configured using the first information. These five data radio bearers are represented as data radio bearer 1, data radio bearer 2, data radio bearer 3, data radio bearer 4, and data radio bearer 5, respectively. Among them, data radio bearer 1 and data radio bearer 2 belong to the first group of data radio bearers, data radio bearer 3 and data radio bearer 4 belong to the second group of data radio bearers, and data radio bearer 5 belongs to the third group of data radio bearers.

[0125] As a concrete example, suppose the access network device does not instruct the terminal device to activate any of the three sets of data radio bearers mentioned above during the first phase. After a period of time, the access network device decides to activate the first set of data radio bearers via second information. The second information includes a second bit string occupying 3 bits, and the value of the second bit string is '100'. Based on the value of the second bit string, the terminal device determines to activate only the first set of data radio bearers.

[0126] As another concrete example, suppose the access network device has already instructed the terminal device to activate the second set of data radio bearers in the first phase. After a period of time, the access network device decides to activate the first set of data radio bearers and deactivate the second set of data radio bearers via second information. The second information includes a second bit string occupying 3 bits and having a value of '100'. Based on the value of the second bit string, the terminal device confirms the activation of the first set of data radio bearers and the deactivation of the second set of data radio bearers.

[0127] In the second implementation method of the second phase, by introducing a second bit string, one or more groups of data radio bearers configured based on the first information can be managed (activated or deactivated). The second implementation method of the second phase can save signaling overhead, is suitable for batch management of one or more groups of data radio bearers, and has high management efficiency.

[0128] The third implementation method of the second stage

[0129] In the third implementation method of the second phase, the second information may include bearer identification information corresponding to at least one data radio bearer that needs to be activated and / or bearer identification information corresponding to at least one data radio bearer that needs to be deactivated.

[0130] In some embodiments, the second information may include bearer identification information corresponding to at least one data radio bearer that needs to be activated. The data radio bearer that needs to be activated may be a data radio bearer in a deactivated state. In this case, the terminal device can determine which data radio bearers to activate based on the bearer identification information included in the second information.

[0131] In other embodiments, the second information may include bearer identification information corresponding to at least one data radio bearer that needs to be deactivated. The data radio bearer that needs to be deactivated may be an active data radio bearer. In this case, the terminal device can determine which data radio bearers to activate based on the bearer identification information included in the second information.

[0132] In some other embodiments, the second information may include bearer identification information corresponding to at least one data radio bearer that needs to be activated, and bearer identification information corresponding to at least one data radio bearer that needs to be deactivated. In this case, the terminal device can determine which data radio bearers to activate and which data radio bearers to deactivate based on the bearer identification information included in the second information.

[0133] In the third implementation method of the second phase, one or more data radio bearers configured based on the first information can be managed (activated and / or deactivated) based on the bearer identification information included in the second information. The third implementation method of the second phase is suitable for batch management of one or more data radio bearers and has high management efficiency.

[0134] Implementation Method Four for the Second Stage

[0135] In the fourth implementation method of the second phase, the second information may include at least one set of bearer group identification information corresponding to the data radio bearer that needs to be activated and / or at least one set of bearer group identification information corresponding to the data radio bearer that needs to be deactivated.

[0136] In some embodiments, the second information may include bearer group identification information corresponding to at least one set of data radio bearers that need to be activated. The data radio bearers that need to be activated may be data radio bearers in a deactivated state. In this case, the terminal device can determine which set of data radio bearers(s) to activate based on the bearer group identification information included in the second information.

[0137] In other embodiments, the second information may include bearer group identification information corresponding to at least one set of data radio bearers that need to be deactivated. The data radio bearers that need to be deactivated may be data radio bearers that are currently active. In this case, the terminal device can determine which set of data radio bearers(s) to activate based on the bearer group identification information included in the second information.

[0138] In some other embodiments, the second information may include bearer group identifier information corresponding to at least one set of data radio bearers to be activated, and bearer group identifier information corresponding to at least one set of data radio bearers to be deactivated. In this case, the terminal device can determine which set of data radio bearers(s) to activate and which set of data radio bearers(s) to deactivate based on the bearer group identifier information included in the second information.

[0139] Each data radio bearer configured based on the first information can be associated with any of the following: group identifier information, task type identifier information, or session identifier information. The group identifier information, task type identifier information, and session identifier information can all be used to assist the terminal device in confirming which data radio bearers belong to the same group of data radio bearers or serve the same data transmission task. It can be assumed that all data radio bearers serving the same data transmission task belong to the same group of data radio bearers. For example, the first information includes bearer identifier information corresponding to one or more data radio bearers, and the group identifier information, task type identifier information, or session identifier information associated with the corresponding data radio bearer. The terminal device can determine which data radio bearers in one or more data radio bearers configured based on the first information belong to the same group based on the group identifier information, task type identifier information, or session identifier information included in the first information.

[0140] In the fourth implementation method of the second phase, one or more groups of data radio bearers configured based on the first information can be managed (activated and / or deactivated) based on the bearer group identification information included in the second information. The fourth implementation method of the second phase, which manages data radio bearer groups at a granular level, is suitable for batch management of one or more groups of data radio bearers, resulting in high management efficiency.

[0141] As can be seen from the above description of the four implementation methods for the second phase, the access network device can dynamically indicate the subsequent activation status of the data radio bearer configured based on the first information (e.g., information carried in the RRC message) through the second information (e.g., information carried in the MAC CE or DCI). This indication can be achieved through bit mapping or by explicitly including identification information (bearer identifier or bearer group identifier).

[0142] The preceding text has described the method embodiments of this application in detail with specific examples. As can be seen from the above description, on the one hand, the initial activation state of the data radio bearer can be controlled when configuring the data radio bearer based on the first information. In this way, the initial activation state of the data radio bearer can be flexibly configured according to actual service needs. On the other hand, the subsequent state of the data radio bearer can be changed through dynamic instructions. In this way, the utilization efficiency of the radio bearer can be improved (activated when in use, deactivated when not in use). Furthermore, compared to reconfiguring the data radio bearer via RRC messages, the signaling overhead of activating or deactivating the data radio bearer through low-layer signaling (MAC CE or DCI) by the access network device is much smaller.
