Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0109] In some embodiments, the radio bearer may include two types of radio bearers: a signaling radio bearer (SRB) and a data radio bearer (DRB). These two radio bearers have different functions, thereby ensuring the effectiveness of radio transmission through a hierarchical structure based on the two radio bearers. In one embodiment, the SRB can be used to transmit control plane signaling. In another embodiment, the DRB can transmit user plane data.

[0110] In one embodiment, before the large-scale application of AI, the communication network merely served as a transmission conduit. However, with the introduction of AI into 6G, due to the need for endogenous AI, network devices such as base stations can allocate a portion of their computing power to terminals to perform complex calculations, and then return the results to the terminals after completing these calculations. For example, in one embodiment, due to the large number of terminals and their privacy requirements, some calculations can be performed locally on the terminals, with the terminals returning the results to the network devices. In this way, terminals can also allocate a portion of their computing power to the network devices.

[0111] In some embodiments, there are two types of control signaling during AI task execution: (1) Task management type control signaling, such as control signaling for computing task management, for example, signaling used to control the start, suspension, or stop of a task. Since this part involves the application layer, it can be considered that this part is not visible to the access stratum (AS). (2) Partial control signaling for computer resource management. Therefore, a control plane bearer is needed to carry the control signaling during AI task execution, and a user plane bearer is also needed, such as the DRB between the terminal and the gNB, which can be used to carry user plane data during AI task execution.

[0112] Therefore, the execution of AI tasks requires two bearers: one for the control plane and one for the user plane, and these two bearers are related. Thus, the network needs to consider the characteristics of these bearers during the control and admission process.

[0113] In some embodiments, when a terminal becomes mobile, the source base station and the target base station only exchange QoS flow information or the establishment status of the source base station's bearers. The target base station is unaware of the relationship between the bearers, which is not conducive to the target base station's admission control and cannot guarantee the continuity of services.

[0114] To this end, this disclosure proposes an information processing method, communication device, communication system, storage medium, and program product. The method involves a first node sending first information to a second node, enabling the second node to establish a wireless bearer based on the first characteristics of at least one first bearer indicated by the first information. This allows the second node to continue executing a first service associated with at least one first bearer based on the wireless bearer, ensuring the service continuity of the first service.

[0115] Figure 2A is an interactive schematic diagram of an information processing method according to an exemplary embodiment. As shown in Figure 2A, this disclosure relates to an information processing method for a communication system 100. The method includes steps S2101 to S2104.

[0116] In some embodiments, the first node can be one of a terminal and a network device. In one embodiment, the first node can be a terminal. In one embodiment, the first node can be a network device. In one embodiment, the first node can be an access network device.

[0117] In some embodiments, the second node can be one of a terminal and a network device. In one embodiment, the second node can be a terminal. In some embodiments, the second node can be a network device. In one embodiment, the second node can be an access network device.

[0118] In one embodiment, both the first node and the second node can be access network devices. In another embodiment, the first node can be the access network device corresponding to the source cell, and the second node can be the access network device corresponding to the target cell.

[0119] In some embodiments, the first node may be a terminal, and the second node may be the access network device corresponding to the serving cell of the terminal.

[0120] In some embodiments, the second node may be a terminal, and the first node may be the access network device corresponding to the serving cell of the terminal.

[0121] This disclosure describes an embodiment where the first node can be the access network device corresponding to the source cell and the second node can be the access network device corresponding to the target cell.

[0122] In step S2101, the first access network device sends first information to the second access network device.

[0123] In some embodiments, the first access network device may send first information to the second access network device via, for example, an X2 interface.

[0124] In some embodiments, the second access network device may receive first information sent by the first access network device via, for example, an X2 interface.

[0125] In one embodiment, the first access network device may be an access network device that provides services to the terminal before cell handover. In another embodiment, the first access network device may be the source access network device during the terminal's cell handover process.

[0126] In one embodiment, the second access network device may be an access network device that provides services to the terminal after cell handover. In another embodiment, the second access network device may be the target access network device during the terminal's cell handover process.

[0127] In some embodiments, when a terminal needs to perform a cell handover, the first access network device may send first information to the second access network device. In one embodiment, the first access network device may send the first information to the second access network device so that the second access network device can establish a radio bearer based on the first information.

[0128] In some embodiments, a first access network device may send a first message to a second access network device, the first message including first information. In some embodiments, the first message may be used to request a switch of the terminal's serving cell from a first cell to a second cell. In one example, the first message may be a cell handover request message. In one embodiment, the first cell may be provided by the first access network device. In one example, the first cell may be a source cell. In one embodiment, the second cell may be provided by the second access network device. In one example, the second cell may be a target cell.

[0129] In one embodiment, the first access network device may send a first message to the second access network device to request the terminal's serving cell to be switched from the first cell to the second cell while simultaneously sending first information to the second access network device.

[0130] In some embodiments, the first information may be carried in a first information element (IE) of a first message. In one embodiment, the first IE may be a newly added IE in the first message. In one embodiment, the first IE is specifically used to carry the first information. In one embodiment, the first access network device may add a new IE in the first message to specifically carry the first information using the newly added IE.

[0131] In some embodiments, the first information may be carried in a second IE of the first message. In one embodiment, the second IE may be an existing IE in the first message. In one embodiment, the second IE may also be used to carry configuration information of the first access network device. In one example, the second IE may be a sourceConfig IE. In one embodiment, the second IE may also be used to carry context information. In one example, the second IE may be an access context IE. In one embodiment, the access context IE may contain characteristics of at least one first bearer notified to the terminal by the first access network device, thereby allowing the second access network device to learn the characteristics of at least one first bearer based on the access context IE in the first message. In one embodiment, the access context IE may contain characteristics of at least one first bearer requested to be established by the terminal notified to the first access network device, thereby allowing the second access network device to learn the characteristics of at least one first bearer based on the access context IE in the first message.

[0132] In some embodiments, a first access network device may send a second message to a second access network device, the second message including first information. In some embodiments, the second message may be a response message to a third message, which may be used to request the acquisition of the terminal's context information. In one embodiment, the third message may be a terminal context acquisition request message. In one embodiment, the second message may be a terminal context acquisition response message.

[0133] In one embodiment, the first access network device may send a second message to the second access network device to send the first information to the second access network device while responding to a third message sent by the second access network device using the second message.

[0134] In some embodiments, the first information may be used to indicate a first characteristic of at least one first bearer.

[0135] In some embodiments, the first bearer may be a bearer established by the first access network device. In one embodiment, the first bearer may be a transmission channel between the first access network device and the terminal.

[0136] In one embodiment, the first bearer may be a bearer for transmitting control plane signaling. In another embodiment, the first bearer may be a bearer for transmitting control plane signaling between a first access network device and a terminal. In one example, the first bearer may be an SRB.

[0137] In one embodiment, the first bearer may be a bearer for transmitting user plane data. In another embodiment, the first bearer may be a bearer for transmitting control plane signaling between the first access network device and the terminal. In one example, the first bearer may be a DRB or a QoS flow.

[0138] In some embodiments, a first characteristic of at least one first bearer is determined by a first service associated with at least one first bearer. In one embodiment, the characteristics of the first service determine the characteristics of at least one first bearer. In one example, the first service is AI-related; therefore, due to the requirements of AI itself, associated DRBs and SRBs need to be established simultaneously during execution, and based on this, the first access network device can determine the characteristics of the first bearer.

[0139] In some embodiments, the first characteristic may be used to indicate at least one of the following: a first service associated with at least one first bearer; an association relationship between at least one first bearer.

[0140] In some embodiments, the first service may be a service carried by at least one first bearer. In one embodiment, the first service may be associated with data and / or signaling transmitted by at least one first bearer. In one embodiment, when the first service is a sensing service, the data transmitted by at least one first bearer may be sensing data.

[0141] In some embodiments, the first service may include, but is not limited to: AI service and perception service.

[0142] In one embodiment, the association between at least one first bearer can be an association between at least one DRB and at least one SRB. In another embodiment, the association between at least one first bearer can be an association between at least one QoS flow and at least one SRB. In another embodiment, when the number of at least one first bearer is greater than or equal to two, a first characteristic of the at least one first bearer can be used to indicate the association between the at least one first bearer.

[0143] In one embodiment, the association between at least one first bearer can be determined by the association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, a first access network device can determine whether there is an association between at least one first bearer based on whether there is an association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, bearer 1 can be a bearer for transmitting control plane signaling, bearer 2 can be a bearer for transmitting user plane data, and bearer 1 and bearer 2 are bearers associated with the same service. In this case, the first access network device needs to inform the second access network device of the association between bearer 1 and bearer 2 so that the second access network device can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data.

[0144] In some embodiments, the association between at least one first bearer can be used to indicate that at least one first bearer is associated with the same service. In one embodiment, if at least one first bearer is associated with another, then the service associated with the at least one first bearer may be the same service. In one embodiment, if at least one first bearer is not associated with another, then the service associated with the at least one first bearer may be different services.

[0145] In some embodiments, the first information can also be used by the second access network device to establish a radio bearer. In one embodiment, the first access network device can send the first information to the second access network device, so that the second access network device establishes a radio bearer based on the first information.

[0146] In some embodiments, the radio bearer established by the second access network device based on the first information can be used to carry the first service. In one embodiment, the second access network device can learn the characteristics of at least one first bearer based on the received first information, so that when the second access network device performs admission control to determine whether to establish a radio bearer, it can take into account the characteristics of at least one first bearer, so that the radio bearer established by the second access network device can continue to carry the service associated with at least one first bearer, ensuring service continuity.

[0147] In some embodiments, the first information can also be used by the second access network device to determine the purpose of establishing the radio bearer. In one embodiment, the first information can indicate the purpose of establishing the radio bearer. In one example, the first information can indicate that the purpose of establishing the radio bearer may be for AI. In one example, taking AI services as an example, there are two types of control signaling during AI task execution: a first type of control signaling for task management and a second type of control signaling for some functions of computing power management. Therefore, multiple bearers need to be established during AI task execution. In this case, in the request from the first access network device to notify the second access network device to establish a bearer, it is necessary to notify at least one characteristic of the first bearer, such as the purpose for which the radio bearer is used, so that the second access network device can establish the associated radio bearer; conversely, if the second access network device does not know the characteristics of at least one first bearer, it cannot establish the associated radio bearer.

[0148] In some embodiments, the first information may include at least one of a first instruction information, a second instruction information, and a third instruction information.

[0149] In some embodiments, where the first information includes first indication information, the first information can be used to explicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes first indication information, the second access network device can determine, based on the first indication information, that the radio bearer is a radio bearer for a first task.

[0150] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, a first access network device can use the first indication information to inform a second access network device of the first task associated with the radio bearer, so that the second access network device can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0151] In some embodiments, where the first information includes second indication information, the first information can be used to assist the second access network device in establishing a radio bearer that can be used for the first task.

[0152] In some embodiments, the second indication information may be used to indicate the task information of the first task. In one embodiment, the task information of the first task may be used to indicate at least one of the following: the task type of the first task, the computing power requirement of the first task, and the memory requirement of the first task.

[0153] In one embodiment, when the first task belongs to AI services, the task type of the first task may include, but is not limited to, inference tasks and training tasks. In one embodiment, when the first task belongs to perception services, the task type of the first task may include, but is not limited to, perception data analysis tasks and perception data acquisition tasks. In some embodiments, the computing power requirement of the first task can be used to indicate the amount of computing resources required when the first task is executed. In one embodiment, the computing power requirement of the first task can be used to assist the second access network device in establishing a wireless bearer.

[0154] In one embodiment, for an AI task, if the second access network device determines that its computing power is sufficient based on the computing power requirements of the AI ​​task, then the second access network device can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, so as to use the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, if the second access network device determines that its computing power is insufficient based on the computing power requirements of the AI ​​task, then the second access network device can establish a radio bearer for transmitting control plane signaling, so as to use this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0155] In some embodiments, the memory requirement of the first task can be used to indicate the amount of memory resources required when the first task is executed. In one embodiment, the memory requirement of the first task can be used to assist the second access network device in allocating memory resources for the radio bearer when establishing the radio bearer.

[0156] In some embodiments, where the first information includes third indication information, the first information can be used to implicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes third indication information, the second access network device can learn the context of the first task based on the third indication information and determine that the radio bearer is for the first task based on the context of the first task.

[0157] In some embodiments, the third indication information can be used to indicate the context of a first task, which is associated with a radio bearer. In one embodiment, a first access network device can use the third indication information to inform a second access network device of the context of the first task associated with the radio bearer, so that the second access network device can determine that the radio bearer is for the first task, and thus the second access network device can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0158] In step S2102, the first access network device sends second information to the second access network device.

[0159] In some embodiments, the first access network device may send second information to the second access network device via, for example, an X2 interface.

[0160] In some embodiments, the second access network device may receive second information sent by the first access network device via, for example, an X2 interface.

[0161] In some embodiments, the second information can be used to indicate at least one second task. In one embodiment, the at least one second task is associated with a first service. In one embodiment, the first service may include at least one second task, and the at least one second task may include the first task, and may also include other tasks besides the first task. In one embodiment, the first access network device sends the second information to the second access network device so that the second access network device can know the at least one second task associated with the first service based on the second information. Subsequently, after establishing a radio bearer, the second access network device can transmit control plane signaling and / or user plane data during the execution of at least one second task based on the radio bearer, ensuring the service continuity of the first service.

[0162] In some embodiments, the second information may include at least one of the fourth, fifth, sixth, seventh, and eighth indication information.

[0163] In some embodiments, where the second information includes fourth indication information, the second information can be used to assist the second access network device in establishing a radio bearer capable of being used for at least one second task.

[0164] In some embodiments, the fourth indication information may be used to indicate task information for at least one second task. In one embodiment, the task information for the second task may be used to indicate at least one of the following: the task type of the second task, the computing power requirement of the second task, and the memory requirement of the second task.

[0165] In one embodiment, the task information of the second task can be found in the task information of the first task in step S2101, and will not be repeated here.

[0166] In some embodiments, where the second information includes fifth indication information, the second information can be used by the second access network device to determine the QoS requirements of at least one second task.

[0167] In some embodiments, the fifth indication information can be used to indicate the QoS requirements of at least one second task. In one embodiment, the fifth indication information may include at least one QoS parameter indicator, which may be a parameter required for the second task to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0168] In some embodiments, where the second information includes sixth indication information, the second information may be used by the second access network device to determine relevant information of at least one first QoS flow associated with the second task.

[0169] In some embodiments, the sixth indication information may be used to indicate relevant information about at least one first QoS flow associated with the second task. In some embodiments, the first QoS flow may be used to carry user plane data during the execution of the second task. In some embodiments, the relevant information about the first QoS flow may include, but is not limited to: QoS flow identification information and QoS parameters of the QoS flow. In one embodiment, the QoS flow identification information may be used to uniquely identify the QoS flow. In one example, the QoS flow identification information may be a QoS flow identifier (QFI). In some embodiments, the QoS parameters of the QoS flow may include, but are not limited to: processing latency, packet loss rate, data rate, bandwidth, etc.

[0170] In some embodiments, where the second information includes seventh indication information, the second information may also be used to indicate the QoS requirements of the second QoS flow.

[0171] In some embodiments, the seventh indication information can be used to indicate QoS requirements for a second QoS flow. In one embodiment, the second QoS flow is a dedicated QoS flow for a second task. In one embodiment, the seventh indication information may include at least one QoS parameter indicator of the second QoS flow, which may be a parameter that the second QoS flow needs to achieve to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0172] In one embodiment, unlike the fifth indication information, the seventh indication information is a QoS requirement for a QoS stream dedicated to the second task. This QoS stream dedicated to the second task can only be used to transmit user plane data during the execution of the second task and cannot be used to transmit user plane data associated with other tasks.

[0173] In some embodiments, where the second information includes eighth indication information, the second information may also be used to indicate relevant information about at least one radio bearer associated with the second task.

[0174] In some embodiments, the eighth indication information is used to indicate relevant information about at least one radio bearer associated with the second task. In some embodiments, the radio bearer may be used to carry user plane data and / or control plane signaling during the execution of the second task. In one embodiment, the radio bearer may include at least one of an SRB and a DRB. In some embodiments, the relevant information about the radio bearer may include, but is not limited to: radio bearer identification information and QoS flow information corresponding to the radio bearer. In one embodiment, the radio bearer identification information may be used to uniquely identify the radio bearer. In one example, the radio bearer identification information may be a radio bearer identifier (RB identifier, RB ID). In one embodiment, the QoS flow information corresponding to the radio bearer may indicate the mapping relationship between the DRB and the QoS flow.

[0175] In some embodiments, the second information and the first information may be carried in the same message. In one embodiment, the second information and the first information may be carried in a first message. In another embodiment, the second information and the first information may be carried in a second message.

[0176] In some embodiments, the second information and the first information may be carried in different messages. In one embodiment, when the first information is carried in a first message, the second information may be carried in a second message. In one embodiment, when the first information is carried in a second message, the second information may be carried in a first message. In one embodiment, the second information may also be carried in other inter-node messages besides the first and second messages.

[0177] In step S2103, the second access network device establishes a radio bearer based on the first information.

[0178] In some embodiments, when a second access network device receives first information sent by a first access network device, the second access network device can establish a radio bearer based on the first information. In one embodiment, the second access network device can establish a radio bearer based on at least one first characteristic of a first bearer indicated by the first information.

[0179] In one embodiment, the first information can be found in the description of the first information in step S2101, and will not be repeated here.

[0180] In some embodiments, the second access network device may establish a radio bearer based on a first service associated with at least one first bearer indicated by the first feature. In one embodiment, if the first service associated with at least one first bearer indicated by the first feature is an AI service, then the second access network device may establish a radio bearer (e.g., an SRB) for transmitting control plane signaling and a radio bearer (e.g., a DRB) for transmitting user plane data.

[0181] In some embodiments, the second access network device may establish radio bearers based on the association relationship between at least one first bearer indicated by the first feature. In one embodiment, if there is an association relationship between at least one first bearer indicated by the first feature, the second access network device may establish multiple radio bearers with the same association relationship, and the multiple radio bearers may be used to transmit control plane signaling and / or user plane data related to the same service.

[0182] In some embodiments, when the first information includes first indication information, the second access network device can determine the purpose of establishing the radio bearer based on the first indication information. In one example, the second access network device learns from the first indication information that the purpose of establishing the radio bearer is for AI-related tasks. Since performing AI-related tasks typically requires establishing associated SRBs and DRBs, the second access network device will establish them together or one of them. However, there is no situation where only a user plane bearer is established without establishing an SRB, i.e., an anomaly occurs. In one example, if the second access network device has sufficient computing power, it can establish one bearer for transmitting control plane signaling and one bearer for transmitting user plane data. In another example, if the second access network device has insufficient computing power, it can establish one bearer for transmitting control plane signaling. In this case, the second access network device may not need to establish the bearer for transmitting user plane data, and can establish the user plane data bearer when subsequent conditions are met.

[0183] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, when the first information includes the first indication information, the second access network device can determine that the radio bearer is for the first task based on the first indication information. In this case, the second access network device can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0184] In some embodiments, where the first information includes second indication information, the second access network device may establish a radio bearer based on the second indication information, and the radio bearer may be used for the first task.

[0185] In some embodiments, the second indication information can be used to indicate the task information of the first task. In one embodiment, when the first information includes the second indication information, the second access network device can determine the task information of the first task associated with the radio bearer based on the second indication information. In this case, the second access network device considers the task information of the first task when establishing the radio bearer, so that the established radio bearer can be used to transmit control plane signaling and / or user plane data during the execution of the first task.

[0186] In one embodiment, the task information of the first task can be found in the description of the task information of the first task in step S2101, and will not be repeated here.

[0187] In one embodiment, if the first task is an AI task and the second indication information is used to indicate the computing power requirements of the AI ​​task, and if the second access network device determines that its own computing power is sufficient based on the computing power requirements of the AI ​​task, then the second access network device can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, so as to use the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, if the first task is an AI task and the second access network device determines that its own computing power is insufficient based on the computing power requirements of the AI ​​task, then the second access network device can establish a radio bearer for transmitting control plane signaling, so as to use this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0188] In one embodiment, when the second indication information is used to indicate the memory requirements of the first task, the second access network device can establish a radio bearer and allocate memory resources for the radio bearer according to the memory requirements of the first task.

[0189] In some embodiments, where the first information includes third indication information, the second access network device can determine the purpose of establishing the radio bearer based on the first indication information.

[0190] In some embodiments, the third indication information can be used to indicate the context of the first task, which is associated with a radio bearer. In one embodiment, when the first information includes the third indication information, the second access network device determines that the radio bearer is associated with the first task based on the context of the first task indicated by the third indication information, thereby determining that the radio bearer is a radio bearer used for the first task. In this case, the second access network device can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0191] In step S2104, the second access network device sends third information to the first access network device.

[0192] In some embodiments, the second access network device may send third information to the first access network device via, for example, an X2 interface.

[0193] In some embodiments, the first access network device may receive third information sent by the second access network device via, for example, an X2 interface.

[0194] In some embodiments, the third information can be used by the first access network device to determine whether the first service should continue to be executed. In one embodiment, the third information can be used by the first access network device to determine the service continuity of the first service.

[0195] In some embodiments, the third information may include one of the fourth and fifth information.

[0196] In some embodiments, where the third information includes the fourth information, the third information may explicitly indicate whether the first service should continue to be performed.

[0197] In some embodiments, the fourth information can be used to indicate whether the second access network device can continue to perform the first service. In one embodiment, the second access network device can send the fourth information to the first access network device to indicate whether the second access network device can continue to perform the first service, thereby facilitating the first access network device to determine the service continuity of the first service.

[0198] In one embodiment, different values ​​of the fourth information can be used to indicate whether the second access network device can continue to perform the first service. In one embodiment, the fourth information has a first value, indicating that the second access network device can continue to perform the first service. In another embodiment, the fourth information has a second value, indicating that the second access network device cannot continue to perform the first service.

[0199] In one embodiment, if the second access network device supports continuing to execute the first service, the second access network device sends fourth information with a first value to the first access network device. In another embodiment, if the second access network device does not support continuing to execute the first service, the second access network device sends fourth information with a second value to the first access network device.

[0200] In some embodiments, the second access network device may determine the value of the fourth information based on whether it supports continuing to perform the first service.

[0201] In some embodiments, the first access network device may determine whether the first service should continue to be executed based on different values ​​of the received fourth information.

[0202] In some embodiments, where the third information includes the fifth information, the third information may implicitly indicate whether the first service should continue to be performed.

[0203] In some embodiments, the fifth information can be used to indicate whether the second access network device has successfully established a radio bearer. In one embodiment, the second access network device can send the fifth information to the first access network device to indicate whether the radio bearer has been successfully established, thereby enabling the first access network device to determine whether the first service can continue to be executed based on the establishment status of the radio bearer, thus determining the service continuity of the first service.

[0204] In one embodiment, the second access network device successfully establishes a radio bearer, indicating that the first service can continue to be executed. In another embodiment, the second access network device fails to establish a radio bearer, indicating that the first service cannot continue to be executed.

[0205] In one embodiment, different values ​​of the fifth information can be used to indicate whether the second access network device has successfully established a radio bearer. In one embodiment, the fifth information has a first value, indicating that the second access network device has successfully established a radio bearer. In another embodiment, the fifth information has a second value, indicating that the second access network device has not successfully established a radio bearer.

[0206] In one embodiment, if the second access network device successfully establishes a radio bearer, the second access network device sends a fifth message with a first value to the first access network device. In another embodiment, if the second access network device fails to establish a radio bearer, the second access network device sends a fifth message with a second value to the first access network device.

[0207] In some embodiments, the second access network device may determine the value of the fifth information based on whether the radio bearer has been successfully established.

[0208] In some embodiments, the first access network device may determine whether the radio bearer has been successfully established based on different values ​​of the received fifth information, thereby determining whether the first service should continue to be executed.

[0220] In some embodiments, the first node may be a terminal, and the second node may be the access network device corresponding to the serving cell of the terminal.

[0221] In some embodiments, the second node may be a terminal, and the first node may be the access network device corresponding to the serving cell of the terminal.

[0222] This disclosure uses an example where the first node is a terminal and the second node is the access network device corresponding to the serving cell of the terminal.

[0223] In step S2201, the terminal sends the first information to the access network device.

[0224] In some embodiments, the terminal may send first information to the access network device via, for example, the Uu interface.

[0225] In some embodiments, the access network device can receive the first information sent by the terminal through the Uu interface.

[0226] In some embodiments, the access network device may be the access network device corresponding to the serving cell of the terminal. In one embodiment, the access network device provides services to the terminal.

[0227] In some embodiments, where the access network device supports opening its computing power to the terminal, the terminal can send first information to the access network device. In one embodiment, the terminal can send the first information to the access network device so that the access network device can establish a radio bearer based on the first information.

[0228] In some embodiments, the terminal may send a fourth message to the access network device, the fourth message including the first information. In some embodiments, the fourth message may be used to request the access network device to establish a radio bearer. In one example, the fourth message may be a bearer establishment request message.

[0229] In one embodiment, the terminal may send a fourth message to the access network device to request the access network device to establish a radio bearer while simultaneously sending first information to the access network device, thereby enabling the access network device to establish a radio bearer based on the first information.

[0230] In some embodiments, the first information may be used to indicate a first characteristic of at least one first bearer.

[0231] In one embodiment, the first bearer may be a bearer for transmitting control plane signaling. In one example, the first bearer may be an SRB.

[0232] In one embodiment, the first bearer may be a bearer for transmitting user plane data. In one example, the first bearer may be a DRB or a QoS stream.

[0233] In some embodiments, a first characteristic of at least one first bearer is determined by a first service associated with at least one first bearer. In one embodiment, the characteristics of the first service determine the characteristics of at least one first bearer. In one example, the first service is AI-related; therefore, due to the requirements of AI itself, it is necessary to establish associated DRBs and SRBs simultaneously during execution, and the terminal can determine the characteristics of the first bearer based on this.

[0234] In some embodiments, the first characteristic may be used to indicate at least one of the following: a first service associated with at least one first bearer; an association relationship between at least one first bearer. In some embodiments, the first service may be a service carried by at least one first bearer. In one embodiment, the first service may be associated with data and / or signaling transmitted by at least one first bearer. In one embodiment, when the first service is a sensing service, the data transmitted by at least one first bearer may be sensing data.

[0235] In some embodiments, the first service may include, but is not limited to: AI service and perception service.

[0236] In one embodiment, the association between at least one first bearer can be an association between at least one DRB and at least one SRB. In another embodiment, the association between at least one first bearer can be an association between at least one QoS flow and at least one SRB. In another embodiment, when the number of at least one first bearer is greater than or equal to two, a first characteristic of the at least one first bearer can be used to indicate the association between the at least one first bearer.

[0237] In one embodiment, the association between at least one first bearer can be determined by the association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, the terminal can determine whether there is an association between at least one first bearer based on whether there is an association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, bearer 1 can be a bearer for transmitting control plane signaling, and bearer 2 can be a bearer for transmitting user plane data. Bearer 1 and bearer 2 are bearers associated with the same service. In this case, the terminal needs to inform the access network device of the association between bearer 1 and bearer 2 so that the access network device can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data.

[0238] In some embodiments, the association between at least one first bearer can be used to indicate that at least one first bearer is associated with the same service. In one embodiment, if at least one first bearer is associated with another, then the service associated with the at least one first bearer may be the same service. In one embodiment, if at least one first bearer is not associated with another, then the service associated with the at least one first bearer may be different services.

[0239] In some embodiments, the first information can also be used by the access network device to establish a radio bearer. In one embodiment, the terminal can send the first information to the access network device, so that the access network device establishes a radio bearer based on the first information.

[0240] In some embodiments, a radio bearer established by an access network device based on first information can be used to carry a first service. In one embodiment, the access network device can learn the characteristics of at least one first bearer based on the received first information, so that when performing admission control to determine whether to establish a radio bearer, the access network device can take into account the characteristics of at least one first bearer, enabling the radio bearer established by the access network device to continue to carry the service associated with at least one first bearer, thereby ensuring service continuity and improving terminal performance and user experience.

[0241] In some embodiments, the first information can also be used by the access network device to determine the purpose of establishing the radio bearer. In one embodiment, the first information may indicate the purpose of establishing the radio bearer. In one example, the first information may indicate that the purpose of establishing the radio bearer may be for AI.

[0242] In some embodiments, the first information may include at least one of a first instruction information, a second instruction information, and a third instruction information.

[0243] In some embodiments, where the first information includes first indication information, the first information can be used to explicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes first indication information, the access network device can determine, based on the first indication information, that the radio bearer is a radio bearer for a first task.

[0244] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, the terminal can use the first indication information to inform the access network device of the first task associated with the radio bearer, so that the access network device can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0245] In some embodiments, where the first information includes second indication information, the first information can be used to assist the access network device in establishing a radio bearer that can be used for the first task.

[0246] In some embodiments, the second indication information may be used to indicate the task information of the first task. In one embodiment, the task information of the first task may be used to indicate at least one of the following: the task type of the first task, the computing power requirement of the first task, and the memory requirement of the first task.

[0247] In one embodiment, when the first task belongs to AI services, the task type of the first task may include, but is not limited to, inference tasks and training tasks. In one embodiment, when the first task belongs to perception services, the task type of the first task may include, but is not limited to, perception data analysis tasks and perception data acquisition tasks. In some embodiments, the computing power requirement of the first task can be used to indicate the amount of computing resources required when the first task is executed. In one embodiment, the computing power requirement of the first task can be used to assist access network devices in establishing wireless bearers.

[0248] In one embodiment, for an AI task, if the access network device determines that its computing power is sufficient based on the computing power requirements of the AI ​​task, then the access network device can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, so as to use the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, if the access network device determines that its computing power is insufficient based on the computing power requirements of the AI ​​task, then the access network device can establish a radio bearer for transmitting control plane signaling, so as to use this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0249] In some embodiments, the memory requirement of the first task can be used to indicate the amount of memory resources required when the first task is executed. In one embodiment, the memory requirement of the first task can be used to assist the access network device in allocating memory resources for the radio bearer when establishing the radio bearer.

[0250] In some embodiments, where the first information includes third indication information, the first information can be used to implicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes third indication information, the access network device can learn the context of the first task based on the third indication information and determine that the radio bearer is for the first task based on the context of the first task.

[0251] In some embodiments, the third indication information can be used to indicate the context of the first task, which is associated with a radio bearer. In one embodiment, the terminal can use the third indication information to inform the access network device of the context of the first task associated with the radio bearer, so that the access network device can determine that the radio bearer is for the first task, and thus the access network device can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0252] In step S2202, the terminal sends the second information to the access network device.

[0253] In some embodiments, the terminal may send second information to the access network device via, for example, the Uu interface.

[0254] In some embodiments, the access network device may receive second information sent by the terminal via, for example, a Uu interface.

[0255] In some embodiments, the second information can be used to indicate at least one second task. In one embodiment, the at least one second task is related to a first service. In one embodiment, the first service may include at least one second task, and the at least one second task may include the first task, and may also include other tasks besides the first task. In one embodiment, the terminal sends the second information to the access network device so that the access network device can know the at least one second task associated with the first service based on the second information, so that the access network device can subsequently transmit control plane signaling and / or user plane data during the execution of at least one second task based on the radio bearer after establishing the radio bearer, thereby ensuring the service continuity of the first service.

[0256] In some embodiments, the second information may include at least one of the fourth, fifth, sixth, seventh, and eighth indication information.

[0257] In some embodiments, where the second information includes fourth indication information, the second information can be used to assist the access network device in establishing a radio bearer capable of being used for at least one second task.

[0258] In some embodiments, the fourth indication information may be used to indicate task information for at least one second task. In one embodiment, the task information for the second task may be used to indicate at least one of the following: the task type of the second task, the computing power requirement of the second task, and the memory requirement of the second task.

[0259] In one embodiment, the task information of the second task can be found in the task information of the first task in step S2101, and will not be repeated here.

[0260] In some embodiments, where the second information includes fifth indication information, the second information can be used by the access network device to determine the QoS requirements of at least one second task.

[0261] In some embodiments, the fifth indication information can be used to indicate the QoS requirements of at least one second task. In one embodiment, the fifth indication information may include at least one QoS parameter indicator, which may be a parameter required for the second task to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0262] In some embodiments, where the second information includes sixth indication information, the second information can be used by the access network device to determine relevant information of at least one first QoS flow associated with the second task.

[0263] In some embodiments, the sixth indication information may be used to indicate relevant information about at least one first QoS flow associated with the second task. In some embodiments, the first QoS flow may be used to carry user plane data during the execution of the second task. In some embodiments, the relevant information about the first QoS flow may include, but is not limited to: QoS flow identification information and QoS parameters of the QoS flow. In one embodiment, the QoS flow identification information may be used to uniquely identify the QoS flow. In one example, the QoS flow identification information may be a QoS flow identifier (QFI). In some embodiments, the QoS parameters of the QoS flow may include, but are not limited to: processing latency, packet loss rate, data rate, bandwidth, etc.

[0264] In some embodiments, where the second information includes seventh indication information, the second information may also be used to indicate the QoS requirements of the second QoS flow.

[0265] In some embodiments, the seventh indication information can be used to indicate QoS requirements for a second QoS flow. In one embodiment, the second QoS flow is a dedicated QoS flow for a second task. In one embodiment, the seventh indication information may include at least one QoS parameter indicator of the second QoS flow, which may be a parameter that the second QoS flow needs to achieve to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0266] In one embodiment, unlike the fifth indication information, the seventh indication information is a QoS requirement for a QoS stream dedicated to the second task. This QoS stream dedicated to the second task can only be used to transmit user plane data during the execution of the second task and cannot be used to transmit user plane data associated with other tasks.

[0267] In some embodiments, where the second information includes eighth indication information, the second information may also be used to indicate relevant information about at least one radio bearer associated with the second task.

[0268] In some embodiments, the eighth indication information is used to indicate relevant information about at least one radio bearer associated with the second task. In some embodiments, the radio bearer may be used to carry user plane data and / or control plane signaling during the execution of the second task. In one embodiment, the radio bearer may include at least one of an SRB and a DRB. In some embodiments, the relevant information about the radio bearer may include, but is not limited to: radio bearer identification information and QoS flow information corresponding to the radio bearer. In one embodiment, the radio bearer identification information may be used to uniquely identify the radio bearer. In one example, the radio bearer identification information may be a radio bearer identifier (RB identifier, RB ID). In one embodiment, the QoS flow information corresponding to the radio bearer may indicate the mapping relationship between the DRB and the QoS flow.

[0269] In some embodiments, the second information and the first information may be carried in the same message. In one embodiment, the second information and the first information may be carried in a first message. In another embodiment, the second information and the first information may be carried in a second message.

[0270] In some embodiments, the second information and the first information may be carried in different messages. In one embodiment, when the first information is carried in a first message, the second information may be carried in a second message. In one embodiment, when the first information is carried in a second message, the second information may be carried in a first message. In one embodiment, the second information may also be carried in other inter-node messages besides the first and second messages.

[0271] In step S2203, the access network device establishes a radio bearer based on the first information.

[0272] In some embodiments, when an access network device receives first information sent by a terminal, the access network device can establish a radio bearer based on the first information. In one embodiment, the access network device can establish a radio bearer based on a first characteristic of at least one first bearer indicated by the first information.

[0273] In one embodiment, the first information can be found in the description of the first information in step S2201, and will not be repeated here.

[0274] In some embodiments, the access network device may establish a radio bearer based on a first service associated with at least one first bearer indicated by the first feature. In one embodiment, if the first service associated with at least one first bearer indicated by the first feature is an AI service, then the access network device may establish a radio bearer (e.g., an SRB) for transmitting control plane signaling and a radio bearer (e.g., a DRB) for transmitting user plane data.

[0275] In some embodiments, the access network device may establish radio bearers based on the association between at least one first bearer indicated by the first feature. In one embodiment, if there is an association between at least one first bearer indicated by the first feature, the access network device may establish multiple radio bearers with the same association, and the multiple radio bearers may be used to transmit control plane signaling and / or user plane data related to the same service.

[0276] In some embodiments, when the first information includes first indication information, the access network device can determine the purpose of establishing the radio bearer based on the first indication information. In one example, the access network device learns from the first indication information that the purpose of establishing the radio bearer is for AI-related tasks. Since performing AI-related tasks typically requires establishing associated SRBs and DRBs, the access network device will establish them together or one of them. However, there is no situation where only a user plane bearer is established without establishing an SRB, i.e., an anomaly occurs. In one example, if the access network device has sufficient computing power, it can establish one bearer for transmitting control plane signaling and one bearer for transmitting user plane data. In one example, if the access network device has insufficient computing power, it can establish one bearer for transmitting control plane signaling. In this case, the access network device may not need to establish the bearer for transmitting user plane data, and can establish the user plane data bearer later when conditions are met.

[0277] In one embodiment, if the access network device knows the purpose of the radio bearer establishment requested by the terminal, it can better make admission control decisions. In one example, if the access network device knows the purpose of the radio bearer establishment requested by the terminal, it can better determine whether to fully or partially accept the terminal's request when establishing the radio bearer, and whether to perform RRC connection reconstruction. In one example, the access network device sends a Class 1 bearer list for AI services, a Class 2 bearer list for sensing services, and a Class 3 bearer list for communication services. It can then reject or accept the terminal's request in appropriate scenarios. For example, it can ensure that all Class 1 bearers are successfully established or all fail, all Class 2 bearers are successfully established or all fail, and all Class 3 bearers are successfully established or all fail. In one example, if there is a failure in the Class 3 bearer list, RRC connection reconstruction needs to be triggered; however, RRC connection reconstruction does not need to be triggered for Class 1 or Class 2 bearers.

[0278] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, when the first information includes the first indication information, the access network device can determine that the radio bearer is for the first task based on the first indication information. In this case, the access network device can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0279] In some embodiments, where the first information includes second indication information, the access network device can establish a radio bearer based on the second indication information, and the radio bearer can be used for the first task.

[0280] In some embodiments, the second indication information can be used to indicate the task information of the first task. In one embodiment, when the first information includes the second indication information, the access network device can determine the task information of the first task associated with the radio bearer based on the second indication information. In this case, the access network device considers the task information of the first task when establishing the radio bearer, so that the established radio bearer can be used to transmit control plane signaling and / or user plane data during the execution of the first task.

[0281] In one embodiment, the task information of the first task can be found in the description of the task information of the first task in step S2101, and will not be repeated here.

[0282] In one embodiment, when the first task is an AI task and the second indication information is used to indicate the computing power requirements of the AI ​​task, if the access network device determines that its own computing power is sufficient based on the computing power requirements of the AI ​​task, then the access network device can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, so as to use the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, when the first task is an AI task, if the access network device determines that its own computing power is insufficient based on the computing power requirements of the AI ​​task, then the access network device can establish a radio bearer for transmitting control plane signaling, so as to use this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0283] In one embodiment, when the second indication information is used to indicate the memory requirements of the first task, the access network device can establish a radio bearer and allocate memory resources for the radio bearer according to the memory requirements of the first task.

[0284] In some embodiments, where the first information includes third indication information, the access network device can determine the purpose of establishing the radio bearer based on the first indication information.

[0285] In some embodiments, the third indication information can be used to indicate the context of the first task, which is associated with a radio bearer. In one embodiment, when the first information includes the third indication information, the access network device determines that the radio bearer is associated with the first task based on the context of the first task indicated by the third indication information, thereby determining that the radio bearer is a radio bearer used for the first task. In this case, the access network device can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0286] In some embodiments, the access network device may reject a request from a terminal to establish a radio bearer. In one embodiment, if the access network device has insufficient computing power, it may reject the request from the terminal to establish a radio bearer; in this case, step S2203 may be omitted.

[0287] In one embodiment, if the access network device knows that the purpose of establishing the radio bearer requested by the terminal is for AI tasks, the access network device can reject or accept the terminal's request in an appropriate scenario.

[0288] In step S2204, the access network device sends third information to the terminal.

[0289] In some embodiments, the access network device may send third information to the terminal via, for example, a Uu interface.

[0290] In some embodiments, the terminal may receive third information sent by the access network device via, for example, the Uu interface.

[0298] In some embodiments, the terminal may determine whether the first service should continue to be executed based on different values ​​of the received fourth information.

[0299] In some embodiments, where the third information includes the fifth information, the third information may implicitly indicate whether the first service should continue to be performed.

[0300] In some embodiments, the fifth information can be used to indicate whether the access network device has successfully established a radio bearer. In one embodiment, the access network device can send the fifth information to the terminal to indicate whether the radio bearer has been successfully established, thereby enabling the terminal to determine whether the first service can continue to be executed based on the establishment status of the radio bearer, thus determining the service continuity of the first service.

[0301] In one embodiment, the access network device successfully establishes a radio bearer, indicating that the first service can continue to be executed. In another embodiment, the access network device fails to establish a radio bearer, indicating that the first service cannot continue to be executed.

[0316] In some embodiments, the first node may be a terminal, and the second node may be the access network device corresponding to the serving cell of the terminal.

[0317] In some embodiments, the second node may be a terminal, and the first node may be the access network device corresponding to the serving cell of the terminal.

[0318] This disclosure uses an example where the second node is a terminal and the first node is the access network device corresponding to the serving cell of the terminal.

[0319] In step S2301, the access network device sends the first information to the terminal.

[0320] In some embodiments, the access network device may send first information to the terminal via, for example, a Uu interface.

[0321] In some embodiments, the terminal may receive first information sent by the access network device via, for example, the Uu interface.

[0322] In some embodiments, the access network device may be the access network device corresponding to the serving cell of the terminal. In one embodiment, the access network device provides services to the terminal.

[0323] In some embodiments, where the terminal supports opening its algorithm to the access network device, the access network device sends first information to the terminal. In one embodiment, the access network device may send the first information to the terminal so that the terminal can establish a radio bearer based on the first information.

[0324] In some embodiments, the access network device may send a fifth message to the terminal, the fifth message including the first information. In some embodiments, the fifth message may be used to request the terminal to establish a radio bearer. In one example, the fifth message may be a bearer establishment request message.

[0325] In one embodiment, the access network device may send a fifth message to the terminal to send first information to the terminal while requesting the terminal to establish a radio bearer using the fifth message, thereby enabling the terminal to establish a radio bearer based on the first information.

[0326] In some embodiments, the first information may be used to indicate a first characteristic of at least one first bearer.

[0327] In one embodiment, the first bearer may be a bearer for transmitting control plane signaling. In one example, the first bearer may be an SRB.

[0328] In one embodiment, the first bearer may be a bearer for transmitting user plane data. In one example, the first bearer may be a DRB or a QoS stream.

[0329] In some embodiments, a first characteristic of at least one first bearer is determined by a first service associated with at least one first bearer. In one embodiment, the characteristics of the first service determine the characteristics of at least one first bearer. In one example, the first service is AI-related; therefore, due to the requirements of AI itself, it is necessary to establish associated DRBs and SRBs simultaneously during execution, and the terminal can determine the characteristics of the first bearer based on this.

[0330] In some embodiments, the first characteristic may be used to indicate at least one of the following: a first service associated with at least one first bearer; an association relationship between at least one first bearer. In some embodiments, the first service may be a service carried by at least one first bearer. In one embodiment, the first service may be associated with data and / or signaling transmitted by at least one first bearer. In one embodiment, when the first service is a sensing service, the data transmitted by at least one first bearer may be sensing data.

[0331] In some embodiments, the first service may include, but is not limited to: AI service and perception service.

[0332] In one embodiment, the association between at least one first bearer can be an association between at least one DRB and at least one SRB. In another embodiment, the association between at least one first bearer can be an association between at least one QoS flow and at least one SRB. In another embodiment, when the number of at least one first bearer is greater than or equal to two, a first characteristic of the at least one first bearer can be used to indicate the association between the at least one first bearer.

[0333] In one embodiment, the association between at least one first bearer can be determined by the association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, the access network device can determine whether there is an association between at least one first bearer based on whether there is an association between the data and / or signaling transmitted by at least one first bearer. In one embodiment, bearer 1 can be a bearer for transmitting control plane signaling, and bearer 2 can be a bearer for transmitting user plane data, and bearer 1 and bearer 2 are bearers associated with the same service. In this case, the access network device needs to inform the terminal that there is an association between bearer 1 and bearer 2 so that the terminal can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data.

[0334] In some embodiments, the association between at least one first bearer can be used to indicate that at least one first bearer is associated with the same service. In one embodiment, if at least one first bearer is associated with another, then the service associated with the at least one first bearer may be the same service. In one embodiment, if at least one first bearer is not associated with another, then the service associated with the at least one first bearer may be different services.

[0335] In some embodiments, the first information can also be used by the terminal to establish a radio bearer. In one embodiment, the access network device can send the first information to the terminal so that the terminal establishes a radio bearer based on the first information.

[0336] In some embodiments, a radio bearer established by a terminal based on first information can be used to carry a first service. In one embodiment, the terminal can learn the characteristics of at least one first bearer based on the received first information, so that when the terminal performs admission control to determine whether to establish a radio bearer, it can take into account the characteristics of at least one first bearer, so that the radio bearer established by the terminal can continue to carry the service associated with at least one first bearer, thereby ensuring service continuity and improving network performance and user experience.

[0337] In some embodiments, the first information can also be used by the terminal to determine the purpose of establishing the wireless bearer. In one embodiment, the first information may indicate the purpose of establishing the wireless bearer. In one example, the first information may indicate that the purpose of establishing the wireless bearer may be for AI.

[0338] In some embodiments, the first information may include at least one of a first instruction information, a second instruction information, and a third instruction information.

[0339] In some embodiments, where the first information includes first indication information, the first information can be used to explicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes first indication information, the terminal can determine that the radio bearer is for a first task based on the first indication information.

[0340] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, the access network device can use the first indication information to inform the terminal of the first task associated with the radio bearer, so that the terminal can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0341] In some embodiments, where the first information includes second indication information, the first information can be used to assist the terminal in establishing a wireless bearer that can be used for the first task.

[0342] In some embodiments, the second indication information may be used to indicate the task information of the first task. In one embodiment, the task information of the first task may be used to indicate at least one of the following: the task type of the first task, the computing power requirement of the first task, and the memory requirement of the first task.

[0343] In one embodiment, when the first task belongs to AI services, the task type of the first task may include, but is not limited to, inference tasks and training tasks. In one embodiment, when the first task belongs to perception services, the task type of the first task may include, but is not limited to, perception data analysis tasks and perception data acquisition tasks. In some embodiments, the computing power requirement of the first task can be used to indicate the amount of computing resources required when the first task is executed. In one embodiment, the computing power requirement of the first task can be used to assist the terminal in establishing a wireless bearer.

[0344] In one embodiment, for an AI task, if the terminal determines that its computing power is sufficient based on the AI ​​task's computational requirements, then the terminal can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, using the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, if the terminal determines that its computing power is insufficient based on the AI ​​task's computational requirements, then the terminal can establish a radio bearer for transmitting control plane signaling, using this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0345] In some embodiments, the memory requirement of the first task can be used to indicate the amount of memory resources required when the first task is executed. In one embodiment, the memory requirement of the first task can be used to assist the terminal in allocating memory resources for the radio bearer when establishing the radio bearer.

[0346] In some embodiments, where the first information includes third indication information, the first information can be used to implicitly indicate the purpose of establishing the radio bearer. In one embodiment, where the first information includes third indication information, the terminal can learn the context of the first task based on the third indication information and determine that the radio bearer is for the first task based on the context of the first task.

[0347] In some embodiments, the third indication information can be used to indicate the context of the first task, which is associated with a radio bearer. In one embodiment, the access network device can use the third indication information to inform the terminal of the context of the first task associated with the radio bearer, so that the terminal can determine that the radio bearer is for the first task, and thus the terminal can continue to transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer after the radio bearer is established.

[0348] In step S2302, the access network device sends the second information to the terminal.

[0349] In some embodiments, the access network device may send second information to the terminal via, for example, a Uu interface.

[0350] In some embodiments, the terminal may receive second information sent by the access network device via, for example, the Uu interface.

[0351] In some embodiments, the second information can be used to indicate at least one second task. In one embodiment, the at least one second task is associated with a first service. In one embodiment, the first service may include at least one second task, and the at least one second task may include the first task, and may also include other tasks besides the first task. In one embodiment, the access network device sends the second information to the terminal so that the terminal can know the at least one second task associated with the first service based on the second information, so that the terminal can subsequently transmit control plane signaling and / or user plane data during the execution of at least one second task based on the radio bearer after establishing the radio bearer, thereby ensuring the service continuity of the first service.

[0352] In some embodiments, the second information may include at least one of the fourth, fifth, sixth, seventh, and eighth indication information.

[0353] In some embodiments, where the second information includes fourth indication information, the second information can be used to assist the terminal in establishing a wireless bearer capable of being used for at least one second task.

[0354] In some embodiments, the fourth indication information may be used to indicate task information for at least one second task. In one embodiment, the task information for the second task may be used to indicate at least one of the following: the task type of the second task, the computing power requirement of the second task, and the memory requirement of the second task.

[0355] In one embodiment, the task information of the second task can be found in the task information of the first task in step S2101, and will not be repeated here.

[0356] In some embodiments, where the second information includes fifth indication information, the second information can be used by the terminal to determine the QoS requirements of at least one second task.

[0357] In some embodiments, the fifth indication information can be used to indicate the QoS requirements of at least one second task. In one embodiment, the fifth indication information may include at least one QoS parameter indicator, which may be a parameter required for the second task to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0358] In some embodiments, where the second information includes sixth indication information, the second information may be used by the terminal to determine relevant information about at least one first QoS flow associated with the second task.

[0359] In some embodiments, the sixth indication information may be used to indicate relevant information about at least one first QoS flow associated with the second task. In some embodiments, the first QoS flow may be used to carry user plane data during the execution of the second task. In some embodiments, the relevant information about the first QoS flow may include, but is not limited to: QoS flow identification information and QoS parameters of the QoS flow. In one embodiment, the QoS flow identification information may be used to uniquely identify the QoS flow. In one example, the QoS flow identification information may be a QoS flow identifier (QFI). In some embodiments, the QoS parameters of the QoS flow may include, but are not limited to: processing latency, packet loss rate, data rate, bandwidth, etc.

[0360] In some embodiments, where the second information includes seventh indication information, the second information may also be used to indicate the QoS requirements of the second QoS flow.

[0361] In some embodiments, the seventh indication information can be used to indicate QoS requirements for a second QoS flow. In one embodiment, the second QoS flow is a dedicated QoS flow for a second task. In one embodiment, the seventh indication information may include at least one QoS parameter indicator of the second QoS flow, which may be a parameter that the second QoS flow needs to achieve to meet the QoS requirements. In one embodiment, the at least one QoS parameter indicator may include, but is not limited to, processing latency indicators, packet loss rate indicators, data rate indicators, bandwidth indicators, etc.

[0362] In one embodiment, unlike the fifth indication information, the seventh indication information is a QoS requirement for a QoS stream dedicated to the second task. This QoS stream dedicated to the second task can only be used to transmit user plane data during the execution of the second task and cannot be used to transmit user plane data associated with other tasks.

[0363] In some embodiments, where the second information includes eighth indication information, the second information may also be used to indicate relevant information about at least one radio bearer associated with the second task.

[0364] In some embodiments, the eighth indication information is used to indicate relevant information about at least one radio bearer associated with the second task. In some embodiments, the radio bearer may be used to carry user plane data and / or control plane signaling during the execution of the second task. In one embodiment, the radio bearer may include at least one of an SRB and a DRB. In some embodiments, the relevant information about the radio bearer may include, but is not limited to: radio bearer identification information and QoS flow information corresponding to the radio bearer. In one embodiment, the radio bearer identification information may be used to uniquely identify the radio bearer. In one example, the radio bearer identification information may be a radio bearer identifier (RB identifier, RB ID). In one embodiment, the QoS flow information corresponding to the radio bearer may indicate the mapping relationship between the DRB and the QoS flow.

[0365] In some embodiments, the second information and the first information may be carried in the same message. In one embodiment, the second information and the first information may be carried in a first message. In another embodiment, the second information and the first information may be carried in a second message.

[0366] In some embodiments, the second information and the first information may be carried in different messages. In one embodiment, when the first information is carried in a first message, the second information may be carried in a second message. In one embodiment, when the first information is carried in a second message, the second information may be carried in a first message. In one embodiment, the second information may also be carried in other inter-node messages besides the first and second messages.

[0367] In step S2303, the terminal establishes a wireless bearer based on the first information.

[0368] In some embodiments, when a terminal receives first information sent by an access network device, the terminal can establish a radio bearer based on the first information. In one embodiment, the terminal can establish a radio bearer based on at least one first characteristic of a first bearer indicated by the first information.

[0369] In one embodiment, the first information can be found in the description of the first information in step S2301, and will not be repeated here.

[0370] In some embodiments, the terminal may establish a radio bearer based on a first service associated with at least one first bearer indicated by the first feature. In one embodiment, if the first service associated with at least one first bearer indicated by the first feature is an AI service, then the terminal may establish a radio bearer (e.g., an SRB) for transmitting control plane signaling and a radio bearer (e.g., a DRB) for transmitting user plane data.

[0371] In some embodiments, the terminal may establish radio bearers based on the association relationship between at least one first bearer indicated by the first feature. In one embodiment, if there is an association relationship between at least one first bearer indicated by the first feature, the terminal may establish multiple radio bearers with the same association relationship, and the multiple radio bearers may be used to transmit control plane signaling and / or user plane data related to the same service.

[0372] In some embodiments, when the first information includes first indication information, the terminal can determine the purpose of establishing the radio bearer based on the first indication information. In one example, the terminal learns from the first indication information that the purpose of establishing the radio bearer is for AI-related tasks. Since performing AI-related tasks typically requires establishing associated SRBs and DRBs, the terminal will establish them together or one of them. However, there is no situation where only a user plane bearer is established without establishing an SRB, i.e., an anomaly occurs. In one example, if the terminal has sufficient computing power, it can establish one bearer for transmitting control plane signaling and one bearer for transmitting user plane data. In another example, if the terminal has insufficient computing power, it can establish one bearer for transmitting control plane signaling. In this case, the terminal may not need to establish the bearer for transmitting user plane data, and can establish the user plane data bearer later when the conditions are met.

[0373] In one embodiment, if the terminal knows the purpose of establishing the requested radio bearer, it can better make admission control decisions. In one example, if the terminal knows the purpose of establishing the requested radio bearer, it can better determine whether to fully or partially accept the network request when establishing the radio bearer, and whether to perform RRC connection reconstruction. In one example, the terminal sends a Class 1 bearer list for AI services, a Class 2 bearer list for sensing services, and a Class 3 bearer list for communication services. It can then reject or accept the network request in appropriate scenarios. For example, it can ensure that all Class 1 bearers are successfully established or all fail, all Class 2 bearers are successfully established or all fail, and all Class 3 bearers are successfully established or all fail. In one example, if there is a failure in the Class 3 bearer list, RRC connection reconstruction needs to be triggered; however, RRC connection reconstruction does not need to be triggered for Class 1 or Class 2 bearers.

[0374] In some embodiments, the first indication information can be used to indicate that a radio bearer is associated with a first task. In one embodiment, when the first information includes the first indication information, the terminal can determine that the radio bearer is for the first task based on the first indication information. In this case, the terminal can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0375] In some embodiments, when the first information includes second indication information, the terminal can establish a wireless bearer based on the second indication information, and the wireless bearer can be used for the first task.

[0376] In some embodiments, the second indication information can be used to indicate the task information of the first task. In one embodiment, when the first information includes the second indication information, the terminal can determine the task information of the first task associated with the radio bearer based on the second indication information. In this case, the terminal considers the task information of the first task when establishing the radio bearer, so that the established radio bearer can be used to transmit control plane signaling and / or user plane data during the execution of the first task.

[0377] In one embodiment, the task information of the first task can be found in the description of the task information of the first task in step S2101, and will not be repeated here.

[0378] In one embodiment, when the first task is an AI task and the second indication information is used to indicate the computing power requirements of the AI ​​task, if the terminal determines that its computing power is sufficient based on the computing power requirements of the AI ​​task, then the terminal can establish a radio bearer for transmitting control plane signaling and a radio bearer for transmitting user plane data, so as to use the two radio bearers to transmit control plane signaling and user plane data during the execution of the AI ​​task, respectively. In another embodiment, when the first task is an AI task, if the terminal determines that its computing power is insufficient based on the computing power requirements of the AI ​​task, then the terminal can establish a radio bearer for transmitting control plane signaling, so as to use this radio bearer to transmit control plane signaling during the execution of the AI ​​task, without needing to establish a radio bearer for transmitting user plane data.

[0379] In one embodiment, when the second indication information is used to indicate the memory requirements of the first task, the terminal can establish a wireless bearer and allocate memory resources for the wireless bearer according to the memory requirements of the first task.

[0380] In some embodiments, when the first information includes third indication information, the terminal can determine the purpose of establishing the radio bearer based on the first indication information.

[0381] In some embodiments, the third indication information can be used to indicate the context of the first task, which is associated with a radio bearer. In one embodiment, when the first information includes the third indication information, the terminal determines that the radio bearer is associated with the first task based on the context of the first task indicated by the third indication information, thereby determining that the radio bearer is a radio bearer used for the first task. In this case, the terminal can establish the radio bearer and transmit control plane signaling and / or user plane data during the execution of the first task based on the radio bearer.

[0382] In some embodiments, the terminal may reject a request from the access network device to establish a radio bearer. In one embodiment, if the terminal's computing power is insufficient, the terminal may reject the request from the access network device to establish a radio bearer; in this case, step S2303 may be omitted.

[0383] In one embodiment, if the terminal knows that the purpose of establishing the wireless bearer requested by the network is for AI tasks, the terminal can reject or accept the network request in an appropriate scenario.

[0384] In step S2304, the terminal sends third information to the access network device.

[0385] In some embodiments, the terminal may send third information to the access network device via, for example, the Uu interface.

[0386] In some embodiments, the access network device may receive third information sent by the terminal via, for example, a Uu interface.

[0387] In some embodiments, the third information can be used by the access network device to determine whether the first service should continue to be executed. In one embodiment, the third information can be used by the access network device to determine the service continuity of the first service.

[0388] In some embodiments, the third information may include one of the fourth and fifth information.

[0389] In some embodiments, where the third information includes the fourth information, the third information may explicitly indicate whether the first service should continue to be performed.

[0390] In some embodiments, the fourth information can be used to indicate whether the terminal can continue to perform the first service. In one embodiment, the terminal can send the fourth information to the access network device to indicate whether the terminal can continue to perform the first service, thereby facilitating the access network device to determine the service continuity of the first service.

[0391] In one embodiment, different values ​​of the fourth information can be used to indicate whether the terminal can continue to perform the first service. In one embodiment, the fourth information has a first value, indicating that the terminal can continue to perform the first service. In another embodiment, the fourth information has a second value, indicating that the terminal cannot continue to perform the first service.

[0392] In one embodiment, if the terminal supports continuing to execute the first service, the terminal sends fourth information with a first value to the access network device. In another embodiment, if the terminal does not support continuing to execute the first service, the terminal sends fourth information with a second value to the access network device.

[0393] In some embodiments, the terminal may determine the value of the fourth information based on whether it supports continuing to execute the first service.

[0394] In some embodiments, the access network device may determine whether the first service should continue to be executed based on different values ​​of the received fourth information.

[0395] In some embodiments, where the third information includes the fifth information, the third information may implicitly indicate whether the first service should continue to be performed.

[0396] In some embodiments, the fifth information can be used to indicate whether the terminal has successfully established a radio bearer. In one embodiment, the terminal can send the fifth information to the access network device to indicate whether the radio bearer has been successfully established, thereby enabling the access network device to determine whether the first service can continue to be executed based on the establishment status of the radio bearer, thus determining the service continuity of the first service.

[0397] In one embodiment, if the terminal successfully establishes a radio bearer, it indicates that the first service can continue to be executed. In another embodiment, if the terminal fails to establish a radio bearer, it indicates that the first service cannot continue to be executed.

[0398] In one embodiment, different values ​​of the fifth information can be used to indicate whether the terminal has successfully established a radio bearer. In one embodiment, the fifth information has a first value, indicating that the terminal has successfully established a radio bearer. In another embodiment, the fifth information has a second value, indicating that the terminal has not successfully established a radio bearer.

[0399] In one embodiment, if the terminal successfully establishes a radio bearer, the terminal sends fifth information with a first value to the access network device. In another embodiment, if the terminal fails to establish a radio bearer, the terminal sends fifth information with a second value to the access network device.

[0400] In some embodiments, the terminal may determine the value of the fifth information based on whether the radio bearer has been successfully established.

[0401] In some embodiments, the access network device may determine whether the radio bearer has been successfully established based on different values ​​of the received fifth information, thereby determining whether the first service should continue to be executed.

[0440] In some embodiments, optional implementations of step S3101 can be found in optional implementations of step S2101 in FIG2A, step S2201 in FIG2B and step S2301 in FIG2C, as well as other related parts in the embodiments involved in FIG2A, FIG2B and FIG2C, which will not be repeated here.

[0441] To better understand the embodiments of this disclosure, the following exemplary embodiments will be used to further illustrate this disclosure.

[0442] Example 1 protects a method for notifying a wireless network element of the characteristics of a bearer to be established, so that the wireless network element can establish a wireless bearer.

[0443] In one embodiment, the wireless network element can be a network device, such as a base station. In another embodiment, the wireless network element can be a terminal.

[0444] In one embodiment, the bearer may be a bearer for transmitting control plane signaling. In another embodiment, the bearer may be a bearer for transmitting user plane data.

[0445] In some embodiments, the bearer may include a wireless bearer or a QoS stream, etc.

[0446] In some embodiments, the characteristics of the bearer can indicate what kind of service the bearer is used for, such as AI services or sensing services.

[0447] In some embodiments, bearer characteristics can be used to indicate the association between bearers. In one example, bearer 1 and bearer 2 are bearers associated with the same service; that is, during task execution, one is used to transmit control plane signaling, and the other is used to transmit user plane data. In another example, bearers 1 to 3 are bearers associated with the same service; that is, during task execution, two are used to transmit control plane signaling (these two bearers are used to carry different types of control signaling, such as RAN-transparent signaling and RAN-visible signaling, or high-priority signaling and low-priority signaling), and one is used to transmit user plane data.

[0448] As an example, taking AI services as an example, AI uses two types of control signaling during task execution:

[0449] The first category is used for task management, such as managing computational tasks, including starting, suspending, and stopping tasks. Because this part involves the application layer, it can be considered invisible to ActionScript.

[0450] The second category is for some functions related to computing power management: computing resources include: the ability resources for computing, reading and writing, storage, algorithms, AI models, AI inference, AI training, AI verification, and data distribution, such as how many operations are provided, and the consumption of memory, power, etc.; but not limited to these.

[0451] Therefore, multiple carriers need to be established during the execution of AI tasks.

[0452] Therefore, in requesting a wireless network element to establish a bearer, it is necessary to inform it of the bearer's characteristics, such as its intended purpose, so that the wireless network element can establish the associated bearer. Conversely, if the wireless network element is unaware of these characteristics, it cannot establish the associated bearer.

[0453] As an example, a base station can establish multiple radio bearers for a terminal;

[0454] As an example, the base station can utilize existing SRB signaling, such as SRB2, to notify the terminal to establish an SRB bearer, such as SRBx, for transmitting control plane signaling in AI. This enables signaling interaction during the computing power management process.

[0455] As an example, if computing power allocation is successful during the computing power management process, it can trigger the establishment of a bearer for transmitting user plane data in AI.

[0456] As an example, for the terminal, if the computing power allocation is successful during the computing power management process, a request to establish a DRB can be triggered at the AS layer.

[0457] As an example, the terminal can use existing SRB signaling, such as SRB2, to notify the network to establish a DRB bearer for transmitting user plane data in AI.

[0458] As an example, the terminal can send auxiliary information to the base station, requesting the base station to establish multiple radio bearers for the terminal, including SRB or DRB bearers.

[0459] As an example, the terminal can directly send an SRB or DRB bearer establishment request to the base station, which carries relevant QoS parameter requests, hoping that the base station can establish multiple radio bearers for the terminal, including SRB or DRB bearers.

[0460] Example 2: Base stations can interact with each other to establish the characteristics of the bearer they have established in order to establish a wireless bearer.

[0461] In some embodiments, the first base station may notify the second base station of the characteristics of the bearer it requests to establish in a handover request, so that the second base station can establish a radio bearer.

[0462] In one example, the bearer characteristics can be indicated by a newly added IE in the switch request. In one embodiment, the bearer characteristics can be indicated using the source base station configuration (sourceConfig) or access context (as-Context) in existing inter-node messages. Here, if the access context already contains the characteristics of the bearer established by the original base station notified to the terminal in Embodiment 4 below, the target base station also knows, through this information, that the base stations can exchange the characteristics of the bearers they establish to establish a radio bearer. Alternatively, if the access context already contains the characteristics of the bearer requested to be established by the terminal notified to the original base station in Embodiment 5 below, the target base station also knows, through this information, that the base stations can exchange the characteristics of the bearers they establish to establish a radio bearer.

[0463] In some embodiments, the first base station notifies the second base station of the characteristics of the bearer it requests to establish in a terminal context acquisition response message, so that the second base station can establish a radio bearer.

[0464] In some embodiments, the first base station may notify the second base station of the characteristics of the QoS flow it requests to establish in a handover request, so that the second base station can establish a radio bearer. In one embodiment, the QoS flow may be for AI tasks. In one embodiment, if the second base station is aware of the characteristics of the bearer establishment, it can perform relevant admission control. For example, if the second base station knows that the purpose of the bearer is for AI-related tasks, and AI-related tasks typically require the establishment of associated signaling plane bearers (SRBs) and user plane bearers (DRBs), it will establish them together or one of them. However, there is no situation where only the user plane bearer is established without establishing the SRB, i.e., an anomaly occurs. In one example, if the second base station has sufficient computing power, it can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data. In one embodiment, if the second base station has insufficient computing power, it can establish a bearer for transmitting control plane signaling. In this case, the second base station may not need to establish a bearer for transmitting user plane data, i.e., the user plane data bearer will be established later when conditions are met.

[0465] In some embodiments, base stations can exchange characteristics of the bearers they establish, wherein the characteristics of the bearer can explicitly indicate the purpose of the bearer establishment. In one embodiment, the characteristics of the bearer can be used to indicate whether the DRB is used for an AI task and specific information about the AI ​​task, such as whether the AI ​​task is used for inference or model training, the computing power requirements of the AI ​​task, the memory or storage requirements of the AI ​​task, etc.

[0466] In some embodiments, base stations can exchange characteristics of the bearers they establish, wherein the characteristics of the bearer may implicitly indicate the purpose of the bearer establishment. In one embodiment, the characteristics of the bearer may be used to indicate the context of a task associated with the QoS flow or DRB, such as the context of an AI task, in which case the bearer can be identified as an AI-related bearer.

[0467] In some embodiments, base stations can exchange information about one or more tasks, including the purpose of the task (e.g., AI), specific information about the task (e.g., the AI ​​task is used for inference or the AI ​​task is used for model training), the computing power requirements of the task, the memory or storage requirements of the task, etc. In some embodiments, the information of each task may also include the transmission QoS information of the task (e.g., processing latency requirements), information about one or more QoS flows corresponding to the task (e.g., QoS flow information may include the identifier of the QoS flow, the QoS parameters of the QoS flow (e.g., data rate, packet loss rate, etc.), the dedicated QoS flow requirements of the task (e.g., inference accuracy, inference latency, etc.), and information about one or more radio bearers corresponding to the task, etc.

[0468] In Example 3, the second base station can send feedback messages to the first base station.

[0469] In some embodiments, the second base station may explicitly notify the first base station whether its related services can be continued.

[0470] In some embodiments, the second base station may notify the first base station whether the bearer has been successfully established, implicitly indicating whether the related services can be continued.

[0471] In one example, if the second base station has sufficient algorithms, it can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data. The second base station can notify the first base station of the successful establishment of these two bearers. In this case, the first base station knows that the original AI task can maintain service continuity.

[0472] Example 4: The network can notify the terminal of the characteristics of the bearer it has established in order to establish a wireless bearer.

[0473] In some embodiments, the base station may notify the terminal of the characteristics of the bearer it requests to establish in the bearer request, so as to establish a radio bearer.

[0474] In some embodiments, if the terminal is aware of the characteristics of the bearer establishment, it can perform relevant admission control (i.e., there is no situation where only a user plane bearer is established). In one example, if the terminal has sufficient computing power, it can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data. In one embodiment, if the terminal has insufficient computing power, it can establish a bearer for transmitting control plane signaling; in this case, the terminal may not need to establish a bearer for transmitting user plane data.

[0475] In one embodiment, if the terminal's computing power is insufficient, the terminal can reject the network's request to establish a bearer. For example, if the terminal knows that the purpose of the bearer establishment request sent by the network is for tasks such as AI, it can reject or accept the network's bearer establishment request in an appropriate scenario.

[0476] In one embodiment, if the terminal knows the purpose of the bearer establishment request sent by the network, it can better determine whether to accept all or part of the multiple bearer establishments and whether to re-establish them.

[0477] As an example, the base station sends a Category 1 bearer list for AI, a Category 2 bearer list for Sensing, and a Category 3 bearer list for communication. It can then reject or accept network bearer establishment requests in appropriate scenarios. For instance, it can either successfully establish all Category 1 bearer lists or fail to establish them all; similarly, it can either successfully establish all Category 2 bearer lists or fail to establish them all; and it can also successfully establish all Category 3 bearer lists or fail to establish them all. If any of the Category 3 bearer lists fail, an RRC connection re-establishment needs to be triggered; however, no RRC connection re-establishment needs to be triggered for Category 1 or Category 2 bearers.

[0478] Therefore, because the base station can inform the terminal of the characteristics of the bearer it requests to establish in the bearer request, it is easier for the terminal to make better admission control decisions.

[0479] Example 5: The terminal can notify the network of the characteristics of the bearer it is establishing in order to establish a wireless bearer.

[0480] In some embodiments, a terminal may notify the network of the characteristics of the bearer it requests to establish in a bearer request in order to establish a radio bearer.

[0481] In some embodiments, if the base station is aware of the characteristics of the bearer establishment, it can perform relevant admission control (i.e., there is no situation where only a user plane bearer is established). In one example, if the base station has sufficient computing power, it can establish a bearer for transmitting control plane signaling and a bearer for transmitting user plane data. In one embodiment, if the base station has insufficient computing power, it can establish a bearer for transmitting control plane signaling; in this case, the base station may not need to establish a bearer for transmitting user plane data.

[0482] In this way, the terminal can inform the network of the characteristics of the bearer it requests to establish in the bearer request, which makes it easier for the base station to make admission control decisions.

[0483] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0484] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through a configuration file, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0485] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a CPU, microprocessor, graphics processing unit (GPU) (which can be understood as a microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an ASIC or PLD, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
