Network nodes can share computing power with terminals to help them perform calculations. However, in the process of the entity providing computing power sending the processed information to the terminal, there are still some technical problems that need to be solved. Summary of the Invention

[0003] The embodiments of this disclosure provide methods and apparatuses for sending and receiving information, entities, network devices, and storage media to address technical problems in the related art.

[0004] According to a first aspect of the present disclosure, an information sending method is proposed, which is executed by a first entity.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0093] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0094] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0095] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto.

[0097] In some embodiments, with the development of communication technology, the demand for network and computing power for services is more urgent. For example, the demand for immersive business communication will reach a transmission rate of 4Tbps and a latency of milliseconds. The computing power demand for autonomous driving and smart factories is expected to increase by 390 times and 110 times, respectively.

[0098] For example, by offloading services to edge computing platforms, faster network service response times can be provided, data backhaul costs can be reduced, and edge-limited computing power can be utilized. This can play a role in meeting real-time business needs, application intelligence, and security and privacy protection.

[0099] For example, computing power is the ability of nodes with computing capabilities in a network to output specific results by processing data. Computing power resources can be used for at least one of the following: computing, reading and writing, storage, algorithms, AI models, AI inference, AI training, AI verification, and data distribution.

[0100] In a network, the computing power of a terminal is limited and cannot support services that require high computing power. Network nodes can share computing power with the terminal to help the terminal perform calculations.

[0101] The following are examples illustrating several concepts:

[0102] Computing capability: Computing capability is the ability of a node in a network to process data and output specific results. This includes, but is not limited to, computing and read / write (memory or storage) capabilities. Computing capability can be distributed across various types of devices, such as network edge, cloud data center, network terminal, and forwarding node.

[0103] Computing and Network Convergence: A new network architecture for the evolution of computing and network convergence. Through the coordinated scheduling of computing and network resource status, it schedules the services of different applications to the optimal computing nodes through the optimal path, ensuring user experience and global resource optimization.

[0104] Wireless network computing capability: The ability of a node in a wireless communication system to process data and output specific results, including but not limited to computing and read / write (memory or storage) capabilities.

[0105] Wireless network computing node / entity: Wireless computing nodes / entities include wireless devices that can provide computing and storage capabilities through wireless communication systems, terminals connected to the network via wireless communication systems, core network equipment, edge computing devices, and data centers, etc. Infrastructure capable of deploying wireless communication system functions can potentially serve as a wireless computing node / entity.

[0106] Wireless computing nodes / entities can provide terminals with functions such as AI storage, AI computing, AI inference, and AI training, thereby better supporting AI on the terminal side. The aforementioned wireless computing nodes / entities may include AI resource nodes / entities, AI control nodes / entities, model storage nodes / entities, AI management nodes / entities, etc., which can be collectively referred to as AI nodes / entities.

[0107] In some embodiments, in a scenario where a network device shares computing power with a terminal, after the entity providing computing power in the network (e.g., referred to as the first entity) processes information for the terminal, it can send the processed information directly or indirectly to the network device serving the terminal, and then the network device sends it to the terminal.

[0108] For example, for a terminal in an inactive state, the entity providing computing power will send the processed information to the terminal's last serving network device, such as the last serving gNB, also known as the previous serving network device. The last serving network device can initiate a paging process, sending a paging message in its own cell or in the cells of network devices within the Radio Access Network Notification Area (RNA).

[0109] After receiving a paging message, the terminal can trigger a Radio Resource Control (RRC) recovery process to enter the connected state. For example, the network device accessed in the connected state can be called the current serving network device. The current serving network device can request the terminal's context from the last serving network device. Based on the request, the last serving network device can send the information that the entity providing computing power will process to the current serving network device, and then the current serving network device will send the information that the entity providing computing power will process to the terminal.

[0110] As can be seen, in the above process, the entity providing computing power needs to first send the processed data to the last serving network device. Then, the last serving network device initiates RRC recovery from the terminal, and subsequently sends the processed data to the current serving network device to which the terminal has reconnected via RRC. During this process, the processed data needs to be sent from the last serving network device to the current serving network device, and before determining the current serving network device, the last serving network device needs to cache the processed data. When the amount of processed data is large, this will excessively occupy the storage space of the last serving network device and consume a significant amount of communication resources during transmission.

[0111] Figure 2A is an interactive schematic diagram of an information sending method according to an embodiment of the present disclosure.

[0112] In some embodiments, the information transmission method may be executed by a first entity, which may be an entity providing computing power in the network, in a scenario where a network device shares computing power with a terminal. For example, the first entity may be an entity on any node in the network, and the node may be a terminal or a network device.

[0113] As shown in Figure 2A, the information sending method may include the following steps:

[0114] In some embodiments, the first entity may determine first information, such as first information that the first entity needs to send to the terminal.

[0115] For example, the first information could be information obtained by the first entity based on other information. For example, the other information could originate from the terminal or from any node of the network device.

[0116] In some embodiments, the first information includes AI-related information. AI-related information can be any one or more types of data or information that need to be transmitted between the AI ​​entity and the terminal during the AI-related process.

[0117] In some embodiments, AI-related information includes at least one of the following:

[0118] AI models;

[0119] Sample information used to train AI models;

[0120] Validation information used to validate AI models;

[0121] Input to the AI ​​model;

[0122] The output of the AI ​​model.

[0123] It should be noted that the first piece of information is not limited to AI-related information, but may also include other information, such as business information, location information, channel information, etc., and this disclosure does not limit this. The following embodiments mainly use AI-related information as an example to illustrate the technical solution of this disclosure.

[0124] For example, when the AI-related information is an AI model, the sample information used to train the AI ​​model can be provided by the terminal, determined autonomously by the first entity, or provided by any network device.

[0125] For example, the sample information for training the AI ​​model is provided by the terminal. After receiving the sample information, the first entity can train the initial model based on the sample information to obtain the AI ​​model.

[0126] For example, when the first entity is used to process AI-related information, the first entity can also be called an AI entity. For example, an AI entity can include at least one of the following:

[0127] AI resource entities are used to provide AI resources for model training to the terminal.

[0128] AI control entities are used to distribute AI tasks requested by terminals and associate AI resource entities.

[0129] AI storage entities are used for storage operations such as storing AI models and AI training data.

[0130] It should be noted that the aforementioned AI entities can be different AI entities, or they can all correspond to the same AI entity. AI entities can also be referred to as AI nodes, or corresponding AI functions, etc., and the specific names are not limited in this publication.

[0131] In some embodiments, the first entity determines that the terminal is in a disconnected state and caches the first information;

[0132] For example, a non-connected state may include at least one of the following: an idle state or an inactive state.

[0133] After determining the first information that needs to be sent to the terminal, the first entity can determine the state of the terminal. If the terminal is in a connected state, the first information can be sent to the terminal through the network device connected to the terminal. If the terminal is in a disconnected state, the first information can be cached first. After the terminal is determined to enter the connected state, the first information can be sent to the first network device that the terminal accesses in the connected state, and then the first network device can send the first information to the terminal.

[0134] Taking the non-connected state, including the inactive state, as an example. For instance, when the terminal is in the connected state, and the network device it accesses is a second network device, the terminal can request a first entity to perform AI-related tasks for the terminal, such as AI model training. For example, the terminal can send sample information for AI model training to the first entity through the second network device, so that the first entity can perform AI model training.

[0135] For example, the terminal can enter the inactive state before the first entity completes the AI ​​model training. For instance, the second network device can send an RRC release message to the terminal, which carries the suspend configuration. The terminal can enter the inactive state based on the RRC release message.

[0136] For example, the second network device is the last serving gNB, which can be called the last serving network device or the previous serving network device.

[0137] In step S201, the first entity determines that the terminal has entered the connected state.

[0138] In step S202, the first entity sends the first information to the first network device.

[0139] According to embodiments of this disclosure, when the first entity receives the first information that needs to be sent to the terminal, it can determine the state of the terminal. If the terminal is in a disconnected state, the first information may not be sent to the network device associated with the terminal initially; for example, the first information may be cached first, and then sent to the first network device accessed by the terminal after the terminal enters a connected state.

[0140] Accordingly, compared to the situation where the first entity sends the first information to the second network device when the terminal is inactive, and then the second network device sends it back to the first network device, the second network device does not need to cache the first information, thus saving the storage space of the second network device, and also saving the communication resources occupied by sending the first information to the second network device and the second network device sending the first information to the first network device.

[0141] It should be noted that this disclosure does not limit the method by which the first entity determines the state of the terminal. For example, the network device may send indication information to the first entity to indicate the state of the terminal; or the first entity may determine the state of the terminal based on predefined rules (e.g., being in a disconnected state within a specific time range, or being in a connected state within a specific location range).

[0142] The following embodiments mainly use the example of a first entity determining the state of a terminal based on instruction information sent by a network device to illustrate the technical solution of this disclosure.

[0143] In some embodiments, determining that a terminal is in an inactive state includes: the first entity receiving first indication information sent by a second network device, wherein the first indication information is used to indicate that the terminal is in an inactive state.

[0144] For example, after the terminal enters an inactive state, the second network device can send a first indication message to the first entity to indicate that the terminal is in an inactive state.

[0145] In some embodiments, after the terminal enters an inactive state, the second network device may send cache indication information to the first entity (for example, the cache indication information may be carried in the first indication information). The cache indication information may instruct the first entity that if there is first information in the first entity that needs to be sent to the first terminal, the first information should be cached instead of being sent to the network device related to the terminal (e.g., the first network device and the second network device).

[0146] For example, when the first entity receives the cache indication information, it can execute the relevant steps in the embodiment shown in Figure 2A, and send the first information to the first network device after the terminal enters the connected state;

[0147] For example, if the first entity does not receive the cache indication information, it may not perform the relevant steps in the embodiment shown in Figure 2A. For example, the first entity may send the first information to the second network device, and the second network device may send the first information to the first network device after the terminal enters the connected state.

[0148] In some embodiments, the second network device may send first identification indication information to the first entity (e.g., the first identification indication information may be carried in first indication information). For example, the first identification indication information may include at least one of the following: the identifier of the terminal; the identifier of the AI ​​task; the identifier of the second network device; the identifier of the cell in the second network device that provides services to the terminal; the identifier of the core network function (e.g., the Access and Mobility Management Function (AMF)); the identifier of the terminal status; and the identifier of the AI ​​entity.

[0149] For example, the first entity can determine the terminal corresponding to the state indicated by the second network device based on the terminal's identifier;

[0150] For example, the first entity can determine the AI ​​task applied to the processed AI-related information based on the AI ​​task identifier;

[0151] For example, the first entity can determine whether the second network device has passed authentication based on the identifier of the second network device. Only if the second network device has passed authentication can the terminal's status be determined based on the instruction information of the second network device.

[0152] For example, the first entity can determine whether the cell has passed authentication based on the identifier of the cell that provides services to the terminal in the second network device. Only if the cell has passed authentication can the terminal's status be determined according to the instruction information of the second network device.

[0153] For example, the first entity can determine whether the core network function has passed authentication based on the core network function (e.g.) identifier. Only if the core network function has passed authentication can the terminal's status be determined based on the instruction information of the second network device.

[0154] For example, the first entity can determine whether the instruction information sent by the second network device is intended for the first entity based on the AI ​​entity identifier. Only if it is determined that the instruction information is intended for the first entity can the terminal's status be determined based on the instruction information from the second network device.

[0155] For example, the terminal status identifier can be included in the first indication information. The first entity can determine the state of the terminal based on the terminal status identifier, such as connected state, idle state, inactive state, etc.

[0156] In some embodiments, the first entity sends a second indication message to the second network device, wherein the second indication message is used to indicate that the first entity needs to send the first information to the terminal.

[0157] In some embodiments, the second indication information is also used to trigger a second network device paging terminal.

[0158] In some embodiments, when the first entity receives first information that needs to be sent to the terminal, it may send second instruction information to the second network device.

[0159] The second network device can determine that the first entity needs to send the first information to the terminal based on the second instruction information. Then, the second network device can perform operations such as sending the first instruction information to the first entity and paging the terminal so that the first entity can successfully send the first information to the terminal.

[0160] In some embodiments, the first entity may send second identification indication information to the second network device (e.g., the second identification indication information may be carried in a second indication information). For example, the second identification indication information may include at least one of the following: the identifier of the terminal; the identifier of the AI ​​task; the identifier of the core network function (e.g., AMF); the identifier of the AI ​​entity; and the AI ​​information type.

[0161] For example, the second network device can determine the terminal to which the first information in the first entity needs to be sent based on the terminal's identifier;

[0162] For example, the second network device can determine the AI ​​task applied to the AI-related information in the first entity based on the AI ​​task identifier;

[0163] For example, the second network device can determine the type of AI-related information in the first entity based on the type of AI information.

[0164] For example, based on the identifier of the second network device, the second network device can determine whether the indication information sent by the first entity is intended for the second network device. Only if it is determined that the information is intended for the second network device will the paging terminal be triggered and the fourth indication information be sent to the first network device according to the indication information of the first entity.

[0165] For example, the second network device can determine whether the core network function has been verified based on the core network function (e.g., AMF) identifier. Only when the core network function has been verified will it trigger operations such as paging terminal according to the instruction information of the first entity.

[0166] For example, the second network device can determine whether the first entity has passed verification based on the AI ​​entity identifier. Only if the first entity has passed verification will the paging terminal and other operations be triggered based on the instruction information of the first entity.

[0167] It should be noted that the operation of the paging terminal of the second network device can be triggered by the second indication information sent by the first entity, based on the foregoing embodiments, or it can be triggered based on other conditions; this disclosure does not limit this. For example, the second network device can trigger the operation of the paging terminal when downlink data arrives.

[0168] For example, when a second network device triggers a paging terminal, it can directly send a paging message to the terminal, or it can determine the RNA where the terminal is located and then trigger the network device in the RNA to send a paging message.

[0169] In some embodiments, after receiving a paging in an inactive state, the terminal can initiate an RRC recovery process to enter the connected state. For example, if the RRC recovery process requires access to a first network device, the terminal can send an RRC recovery request (RRCResumeRequest) to the first network device. After entering the connected state, the terminal accesses the first network device. After the RRC recovery is completed, the first network device can send an RRC recovery complete (RRCResumeComplete) message to the terminal.

[0170] It should be noted that the first network device and the second network device can be different network devices, or they can be the same network device. In the case where the first network device and the second network device are the same network device, the second network device can receive the first information from the first entity without needing to perform operations such as sending the third instruction information or sending the fourth instruction information in subsequent embodiments.

[0171] In some embodiments, after a terminal accesses a first network device, the first network device may send a UE context retrieval request to a second network to obtain the terminal's context from the second network device.

[0172] In some embodiments, the first entity receives third indication information sent by the second network device; wherein the third indication information is used to instruct the terminal to initiate connection recovery and access the first network device, or the third indication information is used to instruct the terminal to access the first network device after entering the connected state from the inactive state.

[0173] For example, the third indication information can be used by the first entity to determine that the network device accessed by the terminal in the connected state is the first network device, and send the first information to the first network device.

[0174] For example, after receiving a context retrieval request sent by the first network device, the second network device can determine that the terminal has accessed the first network device, and then send a third indication message to the first entity to indicate that the terminal has accessed the first network device, or to indicate that the network device accessed by the terminal after entering the connected state from the inactive state is the first network device.

[0175] Accordingly, the first entity can identify the first network device. For example, the first entity can verify the network device that subsequently requests to establish a connection. If the network device requesting to establish a connection with the first entity is the first network device, the connection will be established and the first information will be sent to the connected network device. If the network device requesting to establish a connection with the first entity is not the first network device, the connection will not be established or the information will not be sent to the connected network device.

[0176] In some embodiments, the second entity may send third identification indication information to the first entity (e.g., the third identification indication information may be carried in the third indication information). For example, the third identification indication information may include at least one of the following: the identifier of the terminal; the identifier of the AI ​​task; the identifier of the core network function (e.g., AMF); the identifier of the AI ​​entity; the identifier of the first network device; and the identifier of the second network device.

[0177] For example, the first entity can determine the terminal corresponding to the third indication information sent by the second network device based on the terminal's identifier;

[0178] For example, the first entity can determine the AI ​​task applied to the processed AI-related information based on the AI ​​task identifier;

[0179] For example, the first entity can determine whether the second network device has passed authentication based on the identifier of the second network device. Only if the second network device has passed authentication can the first entity determine whether the first information needs to be sent to the first network device according to the instruction information of the second network device.

[0180] For example, based on the identifier of the first network device, the first entity can determine whether the first network device has passed authentication. If the first network device has passed authentication, the entity will then establish a connection with the first network device and send the first information to the first network device.

[0181] For example, the first entity can determine whether the core network function has passed the verification based on the core network function (e.g., AMF) identifier. Only if the core network function has passed the verification will the first information be sent to the first network device according to the instruction information of the second network device.

[0182] For example, the first entity can determine whether the instruction information sent by the second network device is intended for the first entity based on the AI ​​entity identifier. Only if it is determined that the instruction information is intended for the first entity can the first entity determine whether the first information needs to be sent to the first network device based on the instruction information of the second network device.

[0183] In some embodiments, the second network device may send a fourth indication message to the first network device, wherein the fourth indication message is used to indicate that the first entity contains first information, such as first information that needs to be sent to the terminal.

[0184] The first network device can determine, based on the first instruction information, that there is first information in the first entity that needs to be sent to the terminal, and then establish a connection with the first entity to receive the first information from the first entity and subsequently send the first information to the terminal.

[0185] For example, the fourth indication information can be carried in the Retrieve UE context Response message.

[0186] In some embodiments, the second network device may send fourth identification indication information to the first network device (e.g., the fourth identification indication information may be carried in the fourth indication information). For example, the fourth identification indication information may include at least one of the following: the identifier of the terminal; the identifier of the AI ​​task; the identifier of the core network function (e.g., AMF); the identifier of the AI ​​entity; the identifier of the first network device; and the identifier of the second network device.

[0187] For example, the first network device can determine the terminal to which the first information in the first entity needs to be sent based on the terminal's identifier;

[0188] For example, the first network device can determine the AI ​​task applied to the AI-related information obtained by the first entity based on the AI ​​task identifier;

[0189] For example, the first network device can determine whether the second network device has passed authentication based on the identifier of the second network device. Only if the second network device has passed authentication can the first entity be identified according to the instruction information of the second network device, and a connection be established with the first entity thereafter.

[0190] For example, based on its identifier, the first network device can determine whether the instruction information is provided to the first network device. Only if it is determined that the instruction information is provided to the first network device will a connection be established with the first entity indicated by the second network device.

[0191] For example, the first network device can determine whether the core network function has been verified based on the core network function (e.g., AMF) identifier. Only if the core network function has been verified can a connection be established with the first entity indicated by the second network device.

[0192] For example, the first entity can determine whether it has passed verification based on the AI ​​entity identifier. Only if the first entity has passed verification will a connection be established with the first entity indicated by the second network device.

[0193] In some embodiments, the first network device may establish a connection with the first entity (e.g., a data transmission channel), and the first entity may send the first information to the first network device, which in turn sends the first information to the terminal.

[0194] It should be noted that the execution order of the steps for establishing a connection between the first network device and the first entity is not fixed. For example, it can be executed before the first network device sends the RRCresumeComplete message to the terminal, or after the first network device sends the RRCresumeComplete message to the terminal, or after the first network device sends the RRCresumeComplete message to the terminal and then performs a path switch.

[0195] Figure 2B is a schematic diagram illustrating the interaction of an entity, network device, and terminal according to an embodiment of the present disclosure.

[0196] As shown in Figure 2B, the second network device can instruct the terminal to enter an inactive state.

[0197] After the terminal enters the disconnected state, the second network device can send a first indication message to the first entity. The first indication message is used to indicate that the terminal is in an inactive state.

[0198] After receiving the first instruction information, if the first entity has completed information processing and obtained the first information that needs to be sent to the terminal (for example, training an AI model based on sample information sent by the terminal), it can cache the first information.

[0199] The second network device can trigger paging of the terminal. Specifically, the second network device can send a paging message to the terminal, or the second network device can trigger a network device in the RNA to send a paging message to the terminal.

[0200] For example, the second network device may trigger paging of the terminal upon receiving a second indication message sent by the first entity, wherein the second indication message is used to instruct the first entity to send first information to the terminal; for example, the second network device may trigger paging of the terminal when it determines that downlink data (downlink data sent to the terminal) has arrived.

[0201] After receiving a paging message, the terminal can perform RRC recovery, for example, by sending an RRC recovery request to the first network device. Once the RRC recovery is complete, the terminal can enter the connected state, where the first network device is the network device it accesses.

[0202] The second network device may choose to send a third indication message to the first entity. The third indication message indicates that the network device accessed by the terminal in the connected state is the first network device. Based on this, the first entity can verify the network devices that subsequently request connection. Only if the network device requesting connection is the first network device will the first information be sent to the connected network device; otherwise, a connection will not be established, or no information will be sent to the connected network device.

[0203] The first network device can receive the fourth indication information sent by the second network device. For example, it can receive the fourth indication information during the RRC recovery process at the terminal, or after the RRC recovery is completed. Based on the fourth indication information, the first network device can determine that the first entity contains the first information that needs to be sent to the terminal.

[0204] The first network device can establish a connection with the first entity and then receive the first information that needs to be sent to the terminal from the first entity.

[0205] Furthermore, the first network device can send the first information to the terminal.

[0206] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.

[0207] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.

[0208] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0209] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0217] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0218] The technical solutions of this disclosure will be further illustrated by several embodiments below.

[0219] In some embodiments, the technical solution of this disclosure is illustrated by taking the first entity as including an AI entity, the second network device as referred to as the first gNB, and the first network device as referred to as the second gNB as an example.

[0220] The first gNB can configure the terminal to enter an inactive state (RRC inactive). The first gNB can also be called the last serving gNB. The first gNB can notify the AI ​​entity that the terminal has entered an inactive state.

[0221] After the AI ​​entity completes model training, it needs to transmit AI data (such as the AI ​​model) to the terminal. If the terminal is in an inactive state at this time, the AI ​​entity can instruct the first gNB to trigger RAN paging, the terminal enters the connected state, connects to a new gNB as the second gNB, and then the AI ​​entity and the second gNB establish a transmission channel, and the AI ​​entity sends the AI ​​model to the second gNB.

[0222] In some embodiments, AI entities include, but are not limited to, any one or more of the following:

[0223] AI resource entity: Provides AI resources for model training at the terminal.

[0224] AI control entity: Responsible for distributing AI tasks and associating with AI resource entities.

[0225] AI storage entity: responsible for storing AI models, AI training data, etc.

[0226] The aforementioned entities can all correspond to the same AI entity, which can also be referred to as an AI node or a corresponding AI function, etc. The specific name is not limited.

[0227] In some embodiments, a gNB, also known as a base station, node, wireless base station, etc., can be used to support the transmission of wireless links and connect to terminals via wireless links.

[0228] In some embodiments, AI data includes, but is not limited to, any one or more of the following: AI training data, AI validation data, AI inference input, AI inference output, AI model, etc. AI data can be used collectively to refer to any one or more types of data information that needs to be transmitted between AI entities in AI-related processes. The following specific invention description uses the transmitted AI data as an example of an AI model, where the AI ​​model includes parameters and / or model architecture related to the AI ​​model.

[0229] In some embodiments, gNB (e.g., first gNB, second gNB) and AI entities can exchange relevant information via Xn messages and NG messages.

[0230] In some embodiments, the first gNB and the second gNB can exchange relevant information through Xn messages.

[0231] In some embodiments, the interaction between the gNB, the AI ​​entity, and the terminal may include one or more of the following steps;

[0232] Step 0: The first gNB configuration terminal enters the inactive state (RRC inactive).

[0233] The terminal is currently in RRC connected state. The first gNB acts as the terminal's current serving gNB. The terminal requests an AI entity to perform relevant AI tasks, such as model training. Before model training is completed, the first gNB configures the terminal to enter an inactive state.

[0234] The first gNB sends an RRC release message to the terminal, which carries the SuspendConfig. Upon receiving this RRC release message, the terminal enters an inactive state. Therefore, the first gNB can also be referred to as the last serving gNB.

[0235] Step 1: The first gNB notifies the AI ​​entity that the terminal enters an inactive state.

[0236] For example, the first gNB sends a first indication message to the AI ​​entity. The indication message can be used to indicate that the terminal has entered an inactive state. When the AI ​​entity receives the first indication message, if the AI ​​entity has AI data (such as an AI model) that needs to be sent to the terminal for the inactive terminal, it needs to cache the corresponding AI data instead of sending it directly to the gNB.

[0237] For example, the first gNB sends a first instruction message to the AI ​​entity. The instruction message can be used to instruct the AI ​​entity that if there is AI data (such as an AI model) that needs to be sent to the terminal, it needs to cache the corresponding AI data instead of sending it directly to the gNB.

[0238] For example, the first indication information may include any one or more of the following: terminal identifier, terminal RRC status indication (e.g., idle state, inactive state, connected state), AI task identifier, first gNB identifier, terminal serving cell identifier corresponding to the first gNB, AMF identifier, and AI entity identifier.

[0239] Step 2-1: The AI ​​entity completes model training and sends a second instruction message to the first gNB, triggering paging by the first gNB.

[0240] Once the AI ​​entity has completed model training for the AI ​​task corresponding to this terminal, if it received the first instruction information in step 1, the AI ​​entity caches the AI ​​model and sends the second instruction information to the first gNB. If it has not received the first instruction information before, the AI ​​entity directly sends the AI ​​model to the first gNB, which then forwards it to the terminal.

[0241] The second indication information is used to indicate that there is data in the AI ​​entity to be transmitted to the terminal. For example, the second indication information is used to indicate that the AI ​​entity has completed model training and needs to send the AI ​​model to the terminal.

[0242] The second indication information may include any one or more of the following: terminal identifier, AI task identifier, first gNB identifier, AMF identifier, AI entity identifier, AI data type, etc.

[0243] When the first gNB receives the second instruction information sent by the AI ​​entity, the first gNB confirms that the paging trigger event is met and initiates paging. The first gNB and / or the gNB in ​​the terminal's RNA initiate paging of the terminal.

[0244] In step 2-2, besides the AI ​​entity instructing the first gNB to trigger paging due to the completion of model training as described in step 2-1, the first gNB may also trigger RAN paging for other reasons (e.g., downlink data arrival).

[0245] Step 3: The terminal receives the paging message, initiates RRC connection recovery, and requests access to the cell corresponding to the second gNB.

[0246] When the terminal receives the paging message, it initiates an RRC connection recovery process, requests access to the second gNB through the RRC connection recovery process, and sends an RRCResumeRequest message to the second gNB.

[0247] In some embodiments, the second gNB and the first gNB can be the same gNB.

[0248] Step 4: The second gNB requests the first gNB to provide the terminal's context. The first gNB informs the second gNB that the AI ​​entity stores the terminal's AI data (e.g., AI model) and needs to be transmitted to the terminal. And / or the first gNB informs the AI ​​entity that the terminal requests to restore the RRC connection and access the cell corresponding to the second gNB.

[0249] In some embodiments, the second gNB sends a Retrieve UE context Request message to the first gNB, and the first gNB sends a third indication message to inform the first gNB that the AI ​​entity stores the terminal's AI data (e.g., an AI model). For example, the third indication message may be included in a Retrieve UE context Response message.

[0250] The third instruction information may include any one or more of the following: terminal identifier, AI task identifier, first gNB identifier, second gNB identifier, AMF identifier, and AI entity identifier.

[0251] In some embodiments, the second gNB sends a Retrieve UE context Request message to the first gNB, and the first gNB sends a fourth indication message to the AI ​​entity, informing the AI ​​entity that the terminal requests to restore the RRC connection and access the second gNB. Alternatively, it can be used to indicate that the terminal has entered the connected state and the second gNB it is connected to.

[0252] The fourth indication information may include any one or more of the following: identifier, RRC status indication (e.g., idle state, inactive state, connected state), AI task identifier, first gNB identifier, second gNB identifier, AMF identifier, and AI entity identifier.

[0253] In some embodiments, if the second gNB is the first gNB, when the gNB receives the RRC Resume Request message sent by the terminal, it can inform the AI ​​entity that the terminal has entered the RRC connection state. At this time, the AI ​​entity can send AI data to the gNB without the need for subsequent step 5.

[0254] Step 5: The second gNB establishes a connection (or data transmission channel) with the AI ​​entity. The AI ​​entity sends the terminal's AI data to the second gNB, and the second gNB forwards this AI data to the terminal.

[0255] Based on the third and / or fourth instruction information in step 4, the second gNB establishes a connection (or data transmission channel) with the AI ​​entity, and the AI ​​entity sends the terminal's AI data to the second gNB.

[0256] The steps in step 5 can be performed before or after the second gNB sends the RRRCResumeComplete message; this disclosure does not limit this.

[0257] The second gNB sends an RRRCResumeComplete message to the terminal. If necessary, it can also execute a Path Switch. Then, the second gNB forwards this AI data to the terminal.

[0258] Based on the above steps, it can be seen that the first gNB notifies the AI ​​entity of the state change, such as informing the AI ​​entity in step 1 that the terminal enters the inactive state, and in step 4 notifying the AI ​​entity that the terminal enters the connected state and the corresponding service gNB.

[0259] The AI ​​entity completes model training and sends a second instruction message to the first gNB, instructing the first gNB to trigger paging.

[0260] The second gNB requests context from the first gNB. The first gNB informs the second gNB that the AI ​​entity stores the terminal's AI data (e.g., AI model) and needs to be transmitted to the terminal, and / or. The first gNB informs the AI ​​entity that the terminal requests to restore the RRC connection and access the cell corresponding to the second gNB.

[0261] The second gNB establishes a connection (or data transmission channel) with the AI ​​entity. The AI ​​entity sends the terminal's AI data to the second gNB, and the second gNB forwards this AI data to the terminal.
