[0031] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0032] Wireless communication system

[0033] FIG. 1 is an example diagram of a system architecture of a wireless communication system 100 to which embodiments of the present application can be applied. The wireless communication system 100 can include a network device 110 and a terminal device 120. The network device 110 can be a device communicating with the terminal device 120. The network device 110 can provide network coverage for a specific geographic area, and can communicate with the terminal device 120 located within the coverage area. The terminal device 120 can access a network, for example, a wireless network, through the network device 110. Optionally, the wireless communication system 100 can further include a network controller, a mobile management entity, and other network entities, for which embodiments of the present application are not limited.

[0034] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, for example, a fifth generation (5G) system or new radio (NR), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), and the like. The technical solutions provided in the present application can also be applied to future communication systems, for example, a sixth generation mobile communication system, for example, a satellite communication system, and the like.

[0035] The terminal device in the embodiments of the present application can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile terminal (MT), a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. The terminal device in the embodiments of the present application can refer to a device providing voice and / or data connectivity for a user, and can be used to connect people, things and machines, such as handheld devices with wireless connection function, vehicle-mounted devices, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer (Pad), a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity, which provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D), etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and the smart home device communicate with each other without relaying the communication signals through the base station.

[0036] The network device in the embodiments of the present application can be a device for communicating with a terminal device. The network device may, for example, be an access network device or a radio access network device. For example, the network device can be a base station. The base station can broadly cover various names in the following or be replaced by the names in the following: Node B (Node B), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof.

[0037] Access control

[0038] Before initiating a call, the terminal device needs to perform access control first. From the perspective of the implementer, access control includes two aspects: from the perspective of the terminal device, the access control procedure is performed by the terminal device itself, which is collectively referred to as unified access control (UAC) in the NR system; from the perspective of the network device, the network device performs the access control procedure according to the "RRC establishment cause" carried in the radio resource control (RRC) setup request (RRCSetupRequest) message. The key of the latter lies in that the non-access stratum (NAS) of the terminal device will look up a mapping table to obtain the "RRC establishment cause" according to the access identity (AI) and the access category (AC) when initiating a call. Then, based on the "RRC establishment cause", the RRC layer encodes the RRC establishment request message and sends it to the network device. How the network device performs access control according to the "RRC establishment cause" is an internal algorithm of the network device, which does not need to be concerned here. If the network device receives the RRC establishment request message initiated by the terminal device, the network device will send an RRC setup message to the terminal device in response to the RRC establishment request message, otherwise the network device will send an RRC reject (RRCReject) message to the terminal device to reject the access request of the terminal device.

[0039] The UAC mechanism involves access identity and access category. The access identity represents the identity characteristics of the terminal device itself. In NR, the currently standardized access identities are 0-15, of which 3-10 are undefined. The access category represents the service attributes of the call initiated by the terminal device. The standardized access categories are 0-7, and the operator-defined access categories are 32-63. Other access categories are undefined.

[0040] The specific access control parameters are defined in the system information block (SIB) 1 of the NR cell. The more critical parameters include "UAC barring factor (uac-BarringFactor)", "UAC barring timer (uac-BarringTimer)", and "UAC barring access identity (uac-BarringForAccessIdentity)". The first two parameters are related to the access category. Therefore, when the terminal device performs the UAC procedure in a certain cell, it must first obtain the SIB1 of the cell.

[0041] The procedure of UAC performed by the access stratum (AS) of the terminal device can include the following three steps.

[0042] Step 1

[0043] In step 1, it is determined whether to enter the "green channel" or the "red channel" directly according to the access category provided by the NAS layer. It can be understood that the green channel refers to allowing to initiate random access directly without performing the UAC procedure, and the red channel refers to rejecting random access. Among them, the access category 0 indicates the process of initiating a corresponding paging by the terminal device, and this access category does not need to go through the UAC procedure and will be reflected in the "RRC establishment reason". That is, the called process is unconditionally admitted. The access category 2 indicates an emergency call, and the terminal device needs to perform the UAC procedure only when it is currently in the state of being rejected by the network to establish an RRC connection, that is, the timer T302 is running, otherwise the UAC procedure does not need to be performed. The timer T302 is usually started in the case of being rejected by the network to establish an RRC connection, and the network device may reject the request of the terminal device to establish an RRC connection in the case of being particularly busy, etc.

[0044] In addition to the above cases, if the terminal device finds that the network does not broadcast any related UAC parameters for the current access category, such as the UAC barring parameters, the UAC barring timer and the UAC barring access identifier described above, it is considered to enter the "green channel" directly. During the running of the timer T302, all access categories except the access category 0 and the access category 2 are blocked. When an access category is initiated again during the running of the timer T390, it is directly rejected. In addition to the above-mentioned cases of entering the "green channel" and the "red channel", other access categories will enter the "yellow channel" and perform the procedure of step 2.

[0045] Step 2

[0046] In step 2, the access identifier needs to be checked. Among them, the access identifiers 1, 2, 11-15 are defined in the UAC barring access identifier parameter carried in the SIB1. The UAC barring access identifier parameter may be, for example, a bitmap, the access identifiers set to 1 in the bitmap can enter the "green channel" directly, the access identifiers set to 0 in the bitmap enter the "red channel" directly, and only the access identifier 0 without the corresponding 0 or 1 bitmap needs to continue to perform step 3.

[0047] Step 3

[0048] In step 3, first, the unique control parameters, such as UAC prohibit parameter and UAC prohibit timer, are determined according to the access category. Then, the AS layer of the terminal device generates a random number between 0 and 1. If the random number is less than the value indicated by the UAC prohibit parameter, it is considered that the UAC procedure is passed, otherwise the timer T390 is started, and the length of the timer T390 can be determined according to the time indicated by the UAC prohibit timer, for example, equal to (0.7 + 0.6 x UAC prohibit timer).

[0049] Machine learning

[0050] Machine learning (ML) is one of the ways to realize artificial intelligence (AI), which provides the system with the ability to automatically learn and improve from experience without explicit programming. Machine learning can be divided into three categories, namely supervised learning, unsupervised learning and reinforcement learning.

[0051] Supervised learning, also known as supervised learning or supervised learning, can learn or create a pattern, such as a function or learning model, from training data, and predict new instances according to the pattern. Training data is composed of input objects (such as vectors) and expected output. The output of the function can be a continuous value (also known as regression analysis), or a predicted classification label (also known as classification). The task of a supervised learner is to observe some pre-labeled training examples (including input and expected output) and predict the output of the function for any possible input. To achieve this purpose, the learner must generalize from existing data to non-observed cases in a "reasonable" way (for example, see induction bias).

[0052] Unsupervised learning is a kind of machine learning technique used to find patterns in data. The input data used by unsupervised learning algorithm is not labeled, which means that only input variables (i.e. independent variables X) are given, and no corresponding data variables (i.e. dependent variables Y) are given. In unsupervised learning, the algorithm itself will discover interesting structures in the data and classify them according to the characteristics or attributes of the data.

[0053] Reinforcement learning emphasizes how to act based on the environment to maximize the expected benefit. Reinforcement learning is the third basic machine learning method in addition to supervised learning and unsupervised learning. Unlike supervised learning, reinforcement learning does not require labeled input-output pairs, nor does it require precise correction of non-optimal solutions. Its focus is on finding a balance between exploration (e.g., exploration of unknown areas) and exploitation (e.g., use of existing knowledge). The trade-off between exploration and exploitation in reinforcement learning is most studied in the multi-armed bandit problem and finite Markov decision processes (MDP). In machine learning problems, the environment is usually abstracted as an MDP, because many reinforcement learning algorithms use dynamic programming methods under this assumption. The main difference between traditional dynamic programming methods and reinforcement learning algorithms is that the latter does not require knowledge of the MDP and is aimed at large-scale MDPs for which exact methods cannot be found.

[0054] The model involved in the embodiments of the present application can be a model obtained by using any one of the learning methods described above, and can be referred to as an AI model or an ML model, which is hereinafter referred to as an AI / ML model.

[0055] Backoff Indicator (BI) mechanism of random access procedure

[0056] The BI mechanism in the random access procedure (or RACH procedure) is a mechanism for managing load and collision resolution on the random access channel (RACH). It is used to indicate the time that the terminal device needs to wait before retransmitting the random access preamble sequence, so as to reduce the collision probability in the random access procedure. The BI value is dynamically determined by the network device according to the load condition of the current cell, and can be notified to the terminal device through the random access response (RAR) message. If the load of the cell is high, the BI value can be large to increase the retransmission interval and reduce the collision. Reasonable setting of the BI value is crucial to network performance. If the BI value is set too small, it can cause excessive retransmission and collision, increasing the load of the network; if the BI value is set too large, it can cause an increase in access delay, affecting user experience.

[0057] Application of AI in wireless communication

[0058] In Release 18 (Rel-18 or R18) of NR, how to improve air interface performance by AI / ML model has been studied. The study is driven by three use cases, including: 1) positioning; 2) beam management; 3) channel state information reporting. In addition, the air interface AI project in Rel-18 also includes some studies on the life cycle management of AI models, such as including model training, model deployment, model inference, model detection, model updating, etc.

[0059] Based on the progress and conclusions of Rel-18 research, Release 19 (Rel-19 or R19) will define a general framework for AI / ML model application in air interface use cases, and will conduct relevant standardization work for AI / ML model in use cases such as positioning and beam management. In addition, the availability of AI / ML models in other use cases, such as mobility, will continue to be explored.

[0060] In the current access control mechanism, the terminal device determines whether to initiate access or the timing of the next access based on the selected random number. In this mechanism, the information of the terminal device is not fully utilized and considered, so that the current mechanism may not be optimal for the access control process of a specific terminal device. For example, the terminal device currently has a delay-sensitive service arrival, but if the random number selected by the terminal device is greater than the corresponding UAC prohibit parameter, the terminal device will consider that access is prohibited, and will need to wait for the timer T390 to expire before initiating the next attempt, thereby increasing the connection establishment delay and reducing the user experience.

[0061] To this end, although the current wireless communication system provides more flexibility than ever before, emphasizing wide applicability to different scenarios and full utilization of limited resources. However, the basic principles of most current work are still mostly based on theoretical modeling of actual communication environments or simple parameter selection to complete, and the gain that can be brought by this basic way of work is gradually weakening in variable scenarios and complex communication environments. In view of this situation, it is necessary to adopt new methods and ideas in combination with traditional wireless communication theory and system, so as to break new ground, break through performance bottlenecks, and further improve the performance of wireless communication systems.

[0062] To this end, the embodiments of the present application provide a method of wireless communication, applying a first model and / or a second model to an access control mechanism of a terminal device, wherein the first model can be deployed in the terminal device, and the second model can be deployed in a network device. In this way, the configuration of access parameters can be optimized, and the access strategy can be dynamically adjusted, thereby effectively improving the performance of the access control mechanism and realizing the intelligentization and high efficiency of the access process.

[0063] The technical solutions of the embodiments of the present application are described below in combination with FIG. 2 to FIG. 5. The method 200 shown in FIG. 2 and FIG. 3 describes a first model deployed in a terminal device, and the method 300 shown in FIG. 4 and FIG. 5 describes a second model deployed in a network device.

[0064] FIG. 2 is a flowchart of a wireless communication method provided by an embodiment of the present application.

[0065] As shown in FIG. 2, in step 210, a terminal device determines first information according to a first model.

[0066] The first information is used for uplink access of the terminal device, and the uplink access includes access control and / or random access. For example, the access control can be the UAC described above. The terminal device can determine whether to initiate the uplink access based on the first information, and / or determine a timing of initiating the uplink access based on the first information, and the like.

[0067] The access control and the random access can be two independent processes. Although, in some scenarios, there is a timing relationship between the access control and the random access. However, the first model in the embodiments of the present application can optimize the two processes independently, or in these scenarios, the two processes can be optimized as a whole.

[0068] It can be understood that the first information can be output information of the first model, or the first information can be determined based on the output information of the first model. For example, the output information of the first model can be a probability of success of the uplink access, and the terminal device determines the first information based on the probability.

[0069] The content of the first information is described in detail below.

[0070] In some implementations, the first information can include one or more of the following: uplink access indication information; information of a timer associated with the uplink access; backoff time; power ramping step; and information of a resource for the uplink access.

[0071] The uplink access indication information is used to indicate one or more of the following: whether to pass the UAC process; whether to initiate the uplink access process; and whether to send a preamble for the uplink access to the network device, for example, a preamble in MSG.1 of a random access process. Here, the initiation of the uplink access process can include, for example, initiation of the uplink access process at a predetermined resource and / or at a predetermined time.

[0072] The information of the timer associated with the uplink access can be, for example, a length of the timer, or indication information used to indicate whether to stop the running timer. The timer associated with the uplink access can include, for example, the aforementioned timer T390 and / or timer T302.

[0073] The backoff time is, for example, the aforementioned BI value, which is used to indicate the time required for retransmitting the preamble. The backoff time affects the timing of the terminal device initiating uplink access, i.e., sending the preamble.

[0074] The power ramping step is used to indicate the power required for retransmitting the preamble, wherein the required power is increased based on the power ramping step each time the preamble is retransmitted, which is conducive to improving the transmission success rate of the preamble and improving the access performance of the terminal device.

[0075] In addition, the first information can also include other access parameters, for example, resource parameters related to uplink access, such as resources for the preamble of uplink access.

[0076] Inference of the first model

[0077] Since the first model is a terminal-side model, i.e., the first model is deployed on the terminal device, the inference node of the first model is located on the terminal device. In some implementations, as shown in FIG. 3, the method 200 can further include steps 220 and 230.

[0078] In step 220, the network device sends second information to the terminal device.

[0079] Correspondingly, in step 230, the terminal device receives the second information sent by the network device.

[0080] The second information is used for inference of the first model, for example, the second information can be used as input information of the first model. When performing model inference, the terminal device can obtain information used for model inference by itself, for example, including one or more of the following: downlink measurement results, information of access identification and / or access category, QoS information of uplink data, information of user density obtained by the terminal device, uplink interference information. In addition to the input information that the terminal device can obtain by itself, the terminal device also needs to obtain relevant information from the network device as input information in the inference process of the first model, so as to jointly implement the inference process of the first model based on the input information. The inference result of the first model is the output information of the first model, for example, it can be the aforementioned first information or other related information used to determine the first information.

[0081] In some implementations, the second information obtained by the terminal device from the network device can be determined based on the following information: load information of uplink access resources; and / or, information of user density obtained by the network device.

[0082] The load of the uplink access resource can reflect, for example, the data transmission pressure borne by the uplink access resource. A larger load indicates a larger data transmission pressure, which can cause excessive retransmission and collision; a smaller load indicates a smaller data transmission pressure.

[0083] In some implementations, the load information of the uplink access resource can be represented by a BI value carried in the RAR, for example, a larger BI value represents a larger load, and a smaller BI value represents a smaller load; or the load information of the uplink access resource can be represented by a load level, which can be associated with one or more of the following: collision rate, signal strength of the uplink access channel, and occupation of the uplink access resource. As an example, the above information such as collision rate, signal strength of the uplink access channel, or occupation rate of the uplink access resource with different values or in different value ranges corresponds to different load levels. The uplink access signal is, for example, a random access channel (RACH).

[0084] The load information of the uplink access resource can include, for example, the load situation of the uplink access resource associated with each beam. Optionally, the load information can not only be for the load that has initiated uplink access on the uplink access resource, but also for the load that attempts to initiate uplink access on the uplink access resource.

[0085] In some implementations, the information of the user density obtained by the network device includes the information of the density of active users under each beam.

[0086] In some implementations, the information of the user density obtained by the network device can be represented by a user density level, which is associated with one or more of the following: resource utilization, maximum data transmission rate, call drop rate, and traffic indicator. As an example, the above information such as resource utilization, maximum data transmission rate, call drop rate, or traffic indicator, etc. with different values or in different value ranges corresponds to different user density levels. The resource utilization can be, for example, the utilization of the uplink access resource.

[0087] Training of the first model

[0088] The training node of the first model can be located in the terminal device or the network device, that is, the training process of the first model can be performed by the terminal device or the network device.

[0089] In some implementations, the first model is trained by the terminal device, and the method 200 can further include that the network device sends third information to the terminal device. Accordingly, the terminal device receives the third information sent by the network device.

[0090] The third information is used for training of the first model. When training the model, the terminal device needs to obtain the third information from the network device as input information in the training process of the first model in addition to the information that can be obtained by the terminal device itself.

[0091] In some implementations, the third information can be determined based on the following information: load information of the uplink access resource; and / or, information of user density obtained by the network device. Here, the third information is determined based on the load information of the uplink access resource and / or the information of user density obtained by the network device, which can be understood as that the third information is the load information of the uplink access resource and / or the information of user density obtained by the network device, or the third information can be further determined based on the load information of the uplink access resource and / or the information of user density obtained by the network device. The specific description of the load information of the uplink access resource and the information of user density obtained by the network device can be referred to the foregoing description, which will not be repeated here for brevity.

[0092] In some other implementations, the first model is trained by the network device, and the method 200 can further include that the terminal device sends fourth information to the network device. Correspondingly, the network device receives the fourth information sent by the terminal device.

[0093] The fourth information is used for training of the first model. When training the model, the network device needs to obtain the fourth information from the terminal device as input information in the training process of the first model in addition to the information that can be obtained by the network device itself.

[0094] In some implementations, the fourth information can be determined based on one or more of the following: downlink measurement result; information of access identification and / or access category for uplink access; quality of service (QoS) information of uplink data; information of user density obtained by the terminal device; uplink interference information; evaluation index related to uplink access.

[0095] The downlink measurement result may, for example, be a measurement result obtained by the terminal device after measuring a downlink reference signal, such as signal strength and / or signal quality of the downlink reference signal.

[0096] The QoS information may, for example, include one or more of the following: radio bearer identification, logical channel identification, logical channel group identification, QoS identification, delay status.

[0097] Here, the information of the user density acquired by the terminal device is not the same as the information of the user density acquired by the network device. The information of the user density acquired by the terminal device may, for example, be determined based on the following manners: the terminal device determines by detecting a Bluetooth signal and / or a WiFi signal; and / or, the terminal device acquires an environment image through a camera and determines based on the environment image. That is, the terminal device determines the corresponding user density through detection of signals and / or images in the surrounding environment.

[0098] The uplink interference condition may, for example, be determined by the terminal device based on monitoring of electrical signals, such as electromagnetic waves, etc., in the surrounding environment.

[0099] The evaluation index may, for example, include one or more of the following: a success rate of uplink access, a latency of uplink access, a power consumption of uplink access. Alternatively, the evaluation index of the success rate of uplink access, the latency of uplink access, the power consumption of uplink access, etc. may be associated with an access environment and / or an access decision of the terminal device. That is, the evaluation index is obtained under a specific access environment and access decision.

[0100] As an example, the information of the access environment may include load information of uplink access resources, user density acquired by the terminal device, downlink measurement results, uplink interference information, etc. The access decision may include the aforementioned uplink access indication information, information of a timer associated with uplink access, backoff time, power ramping step, information of resources for uplink access, etc.

[0101] Alternatively, the access decision is output information in the training process of the first model, which may be sent by the network device to the terminal device, and the terminal device applies the access decision to the access environment to obtain the evaluation index.

[0102] Alternatively, the evaluation index may be a reward in the training process of the first model.

[0103] Management of the first model

[0104] In some implementations, the method 200 may further include that the network device sends fifth information to the terminal device. Correspondingly, the terminal device receives the fifth information sent by the network device. The fifth information is used for management of the first model.

[0105] In some implementations, the fifth information is used to instruct the terminal device to perform one or more of the following in the case that a first condition is met: fallback to a traditional access procedure, i.e., an uplink access process that does not rely on the first model; update the first model; reselect a model; activate or deactivate the first model; report an evaluation index related to uplink access.

[0106] In some implementations, the first condition comprises one or more of: the evaluation index being higher or lower than a first threshold; and / or, the terminal device undergoing a cell handover; the cell accessed by the terminal device not being in a cell list associated with the first model; a value of an access environment of the terminal device being higher or lower than a second threshold; the access environment of the terminal device not matching an access environment associated with the first model.

[0107] For example, the evaluation index being higher or lower than a first threshold can mean that the evaluation index of a current access procedure is higher or lower than a first threshold; or that the evaluation index of N consecutive access procedures is higher or lower than a first threshold; or that the evaluation index of N consecutive access procedures within a predetermined time length is higher or lower than a first threshold, N being a positive integer.

[0108] The cell list associated with the first model is a list of cells to which the first model is adapted. Here, different first models can be configured for different cells, and each first model is applicable to its associated cell. If the cell from which the terminal device initiates uplink access is not in the cell list associated with the first model, the terminal device can perform the above operations for the first model, such as deactivating the first model, falling back to an uplink access procedure that does not depend on the first model, updating the first model, or reselecting another model, etc.

[0109] The access environment, for example, comprises one or more of: load information of uplink access resources, user density obtained by the terminal device, downlink measurement results, uplink interference information.

[0110] For example, model A1 is adapted to load level 1 and load level 2 of uplink access resources, and model A2 is adapted to load level 3 of uplink access resources. If the network device sends the terminal device uplink access resources with load level 1 and load level 2, the terminal device initiates uplink access based on model A1; if the network device sends the terminal device uplink access resources with load level 3, the terminal device switches to model A2 and initiates uplink access based on model A2, or can also switch to a traditional access procedure.

[0111] For another example, model B1 matches load level 1, model B2 matches load level 2, and model B3 matches load level 3. If the network device sends the terminal device uplink access resources with load level 1, the terminal device initiates uplink access based on model B1; when the load level of uplink access resources changes to load level 2, the terminal device needs to switch to model B2 and initiate uplink access based on model B2.

[0112] It can be understood that the inference, training and management processes of the first model described above can be combined with each other or independently executed, and all belong to the protection scope of the embodiments of the present application.

[0113] FIG. 4 is a flowchart of a wireless communication method provided by another embodiment of the present application.

[0114] As shown in FIG. 4, at step 310, the network device determines sixth information according to the second model.

[0115] The sixth information is used for uplink access of the terminal device, and the uplink access includes access control and / or random access. For example, the access control can be the UAC described above. The terminal device can dynamically adjust the parameters and / or configurations related to access based on the sixth information.

[0116] The access control and the random access can be two independent processes. Although, in some scenarios, there is a timing relationship between the access control and the random access. However, the second model in the embodiments of the present application can optimize the two processes independently, or in these scenarios, the two processes can be optimized as a whole.

[0117] It can be understood that the sixth information can be output information of the second model; or the sixth information can be determined based on the output information of the second model, that is, the sixth information is other associated information determined based on the output information of the second model.

[0118] In the following, the content of the sixth information is described in detail.

[0119] In some implementations, the sixth information includes: configuration information of the UAC; and / or, configuration information of the RACH.

[0120] For example, the configuration information of the UAC includes: a UAC barring parameter (uac-BarringFactor) associated with an access category; and / or, a UAC barring timer (uac-BarringTimer) associated with the access category. The network device can use the second model to obtain the corresponding UAC barring parameter and / or UAC barring timer according to different access categories, and broadcast to the terminal device.

[0121] For example, the configuration information of the RACH includes: a number of uplink access resources associated with an SSB; and / or, a number of uplink access resources associated with a characteristic of the terminal device. For example, the characteristic of the terminal device includes small data transmission (SDT), reduced capability (RedCap), slicing, etc. For these characteristics, the terminal device can be configured with a number of uplink access resources matching the characteristics.

[0122] Inference of the second model

[0123] Since the second model is a network-side model, i.e., the second model is deployed on the network device, the inference node of the second model is located on the network device. In some implementations, as shown in FIG. 5, the method 200 can further include step 320 and step 330.

[0124] In step 320, the terminal device sends seventh information to the network device.

[0125] Correspondingly, in step 330, the network device receives the seventh information sent by the terminal device.

[0126] The seventh information is used for inference of the second model, for example, the seventh information can be used as input information of the second model. When performing model inference, the network device can obtain information used for model inference by itself, for example, including load information of uplink access resources and / or information of user density obtained by the network device. In addition to the input information that the network device can obtain by itself, the network device also needs to obtain relevant information from the terminal device as input information in the inference process of the second model, so as to jointly implement the inference process of the second model based on the input information. The inference result of the second model is used as output information of the second model, for example, can be the sixth information described above or other relevant information used to determine the sixth information.

[0127] In some implementations, the seventh information obtained by the network device from the terminal device includes one or more of the following: downlink measurement result; position information of the terminal device; movement trajectory information of the terminal device; movement speed information of the terminal device.

[0128] The downlink measurement result can be, for example, a measurement result obtained by the terminal device after measuring a downlink reference signal, such as signal strength and / or signal quality of the downlink reference signal, etc. The movement trajectory information of the terminal device can include historical movement trajectory of the terminal device and / or predicted movement trajectory of the terminal device. The terminal device can use a corresponding movement trajectory prediction model to predict based on the historical movement trajectory to obtain the predicted movement trajectory.

[0129] Training of the second model

[0130] The training node of the second model can be located on the network device, that is, the training process of the first model is performed by the network device.

[0131] In some implementations, the method 300 can further include that the terminal device sends eighth information to the network device. Correspondingly, the network device receives the eighth information sent by the terminal device.

[0132] The eighth information is used for training of the second model. When training the model, the network device needs to obtain relevant information, i.e., the eighth information, from the terminal device as input information in the training process of the second model in addition to the information that can be obtained by the network device itself.

[0133] In some implementations, the eighth information includes one or more of the following information: a downlink measurement result; location information of the terminal device; movement trajectory information of the terminal device; movement speed information of the terminal device; and an evaluation index related to uplink access.

[0134] The downlink measurement result may, for example, be a measurement result obtained by the terminal device after measuring a downlink reference signal, such as a signal strength and / or signal quality of the downlink reference signal. The movement trajectory information of the terminal device may include historical movement trajectory of the terminal device and / or a predicted movement trajectory of the terminal device. The terminal device may, for example, predict the predicted movement trajectory based on the historical movement trajectory by using a corresponding movement trajectory prediction model.

[0135] The evaluation index may, for example, include one or more of the following: a success rate of uplink access, a latency of uplink access, and power consumption of uplink access. Optionally, the evaluation index, such as the success rate of uplink access, the latency of uplink access, and the power consumption of uplink access, may be associated with configuration information of UAC and / or associated with configuration information of an uplink access channel, such as configuration information of RACH. That is, the evaluation index is obtained under a specific UAC configuration and RACH configuration. As an example, the UAC configuration may include a UAC barring parameter and a UAC barring timer, and the RACH configuration may include a number of uplink access resources. In the training process of the second model, the corresponding evaluation index may be obtained for different UAC barring parameters, UAC barring timers, and numbers of uplink access resources.

[0136] Optionally, the evaluation index may be used as a reward in the training process of the second model.

[0137] Management of the second model

[0138] In some implementations, the method 300 may further include that the network device sends ninth information to the terminal device. Correspondingly, the terminal device receives the ninth information sent by the network device. The ninth information is used for management of the second model.

[0139] In some implementations, the ninth information is used to instruct the terminal device to perform one or more of the following in the case where a second condition is met: report an evaluation index related to uplink access; report a downlink measurement result; report location information of the terminal device; report movement trajectory information of the terminal device; and report movement speed information of the terminal device.

[0140] In some implementations, the second condition comprises one or more of the following: the evaluation index is higher or lower than a third threshold value; the downlink measurement result is higher or lower than a fourth threshold value; the moving speed of the terminal device is higher or lower than a fifth threshold value.

[0141] For example, the evaluation index higher or lower than the first threshold value can mean that the evaluation index of the current access procedure is higher or lower than a third threshold value; or the evaluation index of the consecutive N times of access procedures is higher or lower than the third threshold value; or the evaluation index of the consecutive N times of access procedures within a predetermined time length is higher or lower than the third threshold value, and N is a positive integer.

[0142] It can be understood that the inference, training and management processes of the second model described above can be combined with each other or independently executed, and all belong to the protection scope of the embodiments of the present application.
