The following description of the embodiments of this application does not constitute a limitation on the scope of protection of this application.

[0077] The following first introduces the relevant technologies and terms of the embodiments of the present application.

[0078] 1. Artificial intelligence.

[0079] As services become increasingly diverse, current communication systems must meet diverse requirements, including ultra-high speeds, ultra-low latency, ultra-high reliability, and a vast number of connections. This complicates network planning, configuration, and resource scheduling. The increasing frequency of communication used in communication systems places higher demands on base station energy efficiency. These new requirements, scenarios, and features present unprecedented challenges to the planning, maintenance, and efficient operation of communication systems.

[0080] Network planning, network configuration self-optimization, and resource scheduling based on manual experience or simple algorithms have drawbacks such as being time-consuming, costly, and having poor adaptability of self-optimization and scheduling algorithms, and are therefore unable to cope with these new challenges.

[0081] Introducing AI and machine learning (ML) into communications systems can significantly improve the efficiency of network planning, configuration, and resource scheduling, enabling intelligent networks. AI can simulate arbitrary nonlinear models, effectively adapting to real-world environments and pushing performance limits.

[0082] The specific process is as follows: AI and ML acquire large amounts of data, perform model training and / or decision reasoning on the acquired data through ML algorithms, and output AI models and / or decision results (such as business data volume forecasts within a certain period of time in the future).

[0083] 2. Terminal device historical information.

[0084] Access network equipment can optimize terminal device performance based on the terminal device's mobility history information.

[0085] In one possible scenario, the access network device can assess the approximate movement speed of the terminal device based on the terminal device's historical movement information, thereby configuring appropriate measurement parameters for the terminal device. For example, when the terminal device is moving at high speed, the access network device can set a shorter timer to trigger the terminal device to submit measurement reports more quickly, thereby reducing the occurrence of handover failures. The access network device can also select a more appropriate target cell for the terminal device based on the terminal device's historical movement information. For example, when the terminal device is moving at high speed, the access network device can select a cell with greater coverage for the terminal device to reduce the number of handovers required by the terminal device.

[0086] When the terminal device is in a connected state, the terminal device can report mobile history information to the access network device based on the request of the access network device. The historical mobile information of the terminal device may include information on up to 16 cells that have been visited recently (including information on the service cell of the terminal device in the connected state, information on the cell where the terminal device resides when it is in an idle state (idle) and an inactive state (inactive), or at least one of the terminal device entering other radio access technology (radio access network, RAT) systems or leaving the service). The information of each of the above cells includes the global cell identity (CGI) corresponding to each cell, the physical cell identifier (PCI), the frequency corresponding to the cell, or at least one of the time spent in each cell.

[0087] 3. Terminal device switching process.

[0088] Figure 1 is a schematic diagram of a process for a terminal device to switch from a source cell of a first access network device to a target cell of a second access network device. As shown in Figure 1, the process includes the following steps:

[0089] S110: The first access network device sends a handover request to the second access network device. Correspondingly, the second access network device receives the handover request from the first access network device.

[0090] The switching request includes the movement history information of the terminal device recorded by the source base station and the movement history information of the terminal device reported by the terminal device to the first access network device.

[0091] S120: The second access network device sends a handover request acknowledgement to the first access network device. Correspondingly, the first access network device receives the handover request acknowledgement from the second access network device.

[0092] Through the above process, the target base station can obtain the movement history information of the terminal device and the predicted movement history information of the terminal device.

[0093] 4. Data collection process.

[0094] Figure 2 is a schematic diagram of the data collection report initiation process. As shown in Figure 2, the process includes the following steps:

[0095] S210: The first access network device sends a data collection request to the second access network device. Correspondingly, the second access network device receives the data collection request from the first access network device.

[0096] The data collection request is used to request the second access network device to send the terminal device's mobility information to the first access network device. The data collection request may include configuration information such as the period for the second access network device to send the terminal device's mobility information to the first access network device, as configured by the first access network.

[0097] Optionally, the mobility information of the terminal device may be actual mobility information of the terminal device, which may include an identifier of a cell under the second access network device to which the terminal device switches, or information such as the time the terminal device stays in the cell.

[0098] S220: The second access network device sends a data collection response to the first access network device. Correspondingly, the first access network device receives the data collection response from the second access network device.

[0099] If the second access network device agrees to send the mobile information of the terminal device to the first access network device, the second access network device sends a data collection response to the first access network device, and the data collection response indicates to the first access network device that the second access network device confirms and feeds back the mobile information of the terminal device.

[0100] Figure 3 is a schematic diagram of the data collection and reporting process. As shown in Figure 3, the process includes the following steps:

[0101] S310: The second access network device sends a data collection update message to the first access network device. Correspondingly, the first access network device receives the data collection update message from the second access network device.

[0102] The data collection update message is a message fed back by the second access network device based on the data collection request.

[0103] It should be noted that the association relationship between the data collection process shown in Figures 2 and 3 and the switching process shown in Figure 1 is as follows: the data collection process is associated with non-terminal devices, and the switching process is associated with terminal devices. The first access network device can carry a measurement ID (measurement ID) in the switching request message to associate the data collection process. After the second access network device receives the switching request, it can retrieve the corresponding data collection process according to the measurement ID, and then learn the configuration information in the data collection request, and in which data collection update message it is sent to the first access network device, so that the second access network device determines the data collection update message according to the corresponding configuration information, and sends it to the first access network device in the corresponding data collection update message. Among them, the measurement ID can also be called the data collection ID (data collection ID), or it can be replaced with other names, and the embodiments of the present application do not limit this.

[0105] The first access network device is configured to send first configuration information to the second access network device and receive first information from the second access network device.

[0106] The second access network device is configured to receive the first configuration information from the first access network device and send the first information to the first access network device.

[0107] In an embodiment of the present application, first configuration information is used to instruct a second access network device to send first information to a first access network device, the first information being used to determine second mobility information, the second mobility information being updated first mobility information, the first mobility information being predicted mobility information of a terminal device in multiple cells, the multiple cells including cells corresponding to one or more access network devices, wherein the one or more access network devices include the second access network device.

The terminal may be mobile or fixed.

[0110] Optionally, the access network device involved in the present application (including the first access network device and the second access network device) includes an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in a long term evolution (LTE) system or an enhanced LTE (LTE-advanced, LTE-A) system, such as a traditional macro base station eNB and a micro base station eNB in ​​a heterogeneous network scenario. Alternatively, it may include a next generation node B (gNB) in a new radio (NR) system. Alternatively, it may include a base station in a future 6G system. Alternatively, it may include a transmission reception point (TRP), a home base station (for example, a home evolved NodeB, or a home Node B, HNB), a base band unit (BBU), a base band pool (BBU pool), or a wireless fidelity (WiFi) access point (AP), etc. Alternatively, it may include a base station in a non-terrestrial network (NTN), that is, it may be deployed on an aircraft or satellite. In the NTN, the network device or access device may serve as a layer 1 (L1) relay, or as a base station, or as an integrated access and backhaul (IAB) node. Alternatively, the network device in the embodiments of the present application may be a device that implements base station functions in the IoT, such as a device that implements base station functions in drone communications, V2X, D2D, or M2M.

[0111] In some possible scenarios, the access network device (including the first access network device and the second access network device) in the embodiments of the present application may also be a module or unit that can implement some functions of the base station. For example, the network device may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be set separately or included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0112] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, the first network device may be a network device or a module of a network device in an open radio access network (open RAN, ORAN) system. In the ORAN system, CU may also be referred to as open (open, O)-CU, DU may also be referred to as O-DU, CU-CP may also be referred to as O-CU-CP, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU.

[0114] It should be noted that the communication system described in the embodiment of the present application is intended to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0115] Optionally, the communication system further includes core network equipment for providing functions such as user connection, user management, and service carrying.

[0116] Optionally, in an embodiment of the present application, the first access network device and / or the second access network device has AI and / or ML prediction capabilities and can predict the mobility information of the terminal device.

[0117] Among them, the AI ​​and / or ML prediction capabilities of the first access network device and / or the second access network device can be implemented by the AI ​​module of the ORAN communication system as shown in Figure 5 or Figure 6. In one possible implementation, the first access network device and / or the second access network device can have AI capabilities (an AI module is built into the device), that is, the first access network device and / or the second access network device have endogenous AI capabilities. In another possible implementation, the first access network device and / or the second access network device do not have AI capabilities and need to complete AI capabilities based on AI-related devices or network elements. When the first access network device and / or the second access network device needs to perform AI-related operations, it requests AI services from the AI-related devices or network elements. The separated ORAN architecture will be introduced below through Figures 5 and 6 respectively.

[0118] Figure 5 is a schematic diagram of the architecture of the ORAN communication system provided by an embodiment of the present application. As shown in Figure 5, the devices in the communication system (e.g., core network devices, access network devices (RAN nodes), and terminal devices) are connected via interfaces (e.g., NG, Xn interfaces) or air interfaces (Uu).

[0119] One or more AI modules may also be provided in one or more devices in the communication system (for clarity, only one is shown in FIG5 ). The access network device may serve as a single RAN node or may include multiple RAN nodes, for example, a CU and a DU. The CU and / or DU may also be provided with one or more AI modules. Optionally, one or more AI models may also be provided in the CU-CP and / or CU-UP.

[0120] In the embodiments of the present application, the AI ​​module is used to implement the corresponding AI function. The AI ​​modules deployed in different devices can be the same or different. Among them, the AI ​​modules can implement different functions based on the parameter configuration of the models of different AI modules.

[0121] In an embodiment of the present application, the model of the AI ​​module can be configured based on at least one of the following parameters: structural parameters (such as the number of neural network layers, the width of the neural network, the connection relationship between layers, the weight of the neuron, the activation function of the neuron, or at least one of the bias in the activation function), input parameters (such as the type of input parameters and / or the dimension of the input parameters), or output parameters (such as the type of output parameters and / or the dimension of the output parameters). Among them, the bias in the activation function can also be called the bias of the neural network.

[0122] In the embodiments of the present application, an AI module may have one or more models, each of which can be inferred to obtain an output, which may include one or more parameters. The learning, training, or inference processes of different models may be deployed on different nodes or devices, or on the same node or device.

[0123] Figure 6 is a schematic diagram of the RIC architecture provided by an embodiment of the present application. As shown in Figure 6, RIC includes near-real time RIC (near-RT RIC) and non-real time RIC (non-RT RIC).

[0124] Among them, near real-time RIC is used for model training and inference. For example, near real-time RIC is used to train AI models and use the AI ​​models for inference. Near real-time RIC can obtain information on the access network device side and / or the terminal device side from RAN nodes (such as CU, CU-CP, CU-UP, DU and / or radio unit (RU)) and / or terminal devices. This information can be used as training data or inference data.

[0125] Optionally, the near real-time RIC may deliver the inference results to the RAN node and / or the terminal device.

[0126] Optionally, the inference results can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the near-real-time RIC delivers the inference results to the DU, which then sends them to the RU.

[0127] Among them, non-real-time RIC is used for model training and reasoning. For example, non-real-time RIC is used to train AI models and use the model for reasoning. Non-real-time RIC can obtain information on the access network device side and / or the terminal device side from RAN nodes (such as CU, CU-CP, CU-UP, DU and / or RU) and / or terminal devices. This information can be used as training data or reasoning data, and the reasoning results can be submitted to the RAN node and / or terminal device.

[0128] Optionally, the inference results can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the non-real-time RIC submits the inference results to the DU, which then sends them to the RU.

[0129] In the embodiment of the present application, the near real-time RIC and the non-real-time RIC can be set up as separate devices respectively.

[0130] Optionally, the near real-time RIC and the non-real-time RIC may also be part of other devices, for example, the near real-time RIC is set in a RAN node (e.g., in a CU or DU), and the non-real-time RIC is set in an operations, administration and maintenance (OAM) device, a cloud server, a core network device, or other network devices.

[0131] Optionally, the relevant functions of the first access network device and the second access network device involved in the present application can be implemented by one device, or by multiple devices together, or by one or more functional modules within a device, or by one or more chips, or by a system on chip (SOC) or a chip system. The chip system can be composed of chips, or can include chips and other discrete devices. The embodiments of the present application do not specifically limit this.

[0132] It is understandable that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0134] Optionally, in one design, the processor 711 may include a program 713 (sometimes also referred to as code or instructions), and the program 713 may be executed on the processor 711 so that the communication device 700 performs the method described in the following embodiments.

[0135] Optionally, the communication device 700 may include one or more memories 712 on which a program 714 (sometimes also referred to as code or instructions) is stored.

For example, the AI ​​module may be a near real-time RIC or a non-real-time RIC.

[0137] Optionally, data may be stored in the processor 711 and / or the memory 712. The processor and the memory may be provided separately or integrated together.

[0138] Optionally, the communication device 700 may further include a transceiver 715 and / or an antenna 716. The processor 711 may also be referred to as a processing unit, which controls the communication device. The transceiver 715 may also be referred to as a transceiver unit, a transceiver, a transceiver circuit, or a transceiver, and is configured to implement the transceiver functions of the communication device via the antenna 716.

[0139] Optionally, in the embodiment of the present application, the processor 711 is a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The processor 711 may also be other devices with processing functions, such as circuits, devices, or software modules, without limitation.

[0140] Optionally, in an embodiment of the present application, the memory 712 may be a read-only memory (ROM) or other types of static storage devices that can store static information and / or instructions, or a random access memory (RAM) or other types of dynamic storage devices that can store information and / or instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, etc., without limitation.

[0142] It should be noted that communication device 700 may be a desktop computer, a portable computer, a network server, a mobile phone, a tablet computer, a wireless terminal, an embedded device, a chip system, or a device having a structure similar to that shown in FIG7 . Furthermore, the structure shown in FIG7 does not limit the communication device. In addition to the components shown in FIG7 , the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0143] In the embodiment of the present application, the chip system can be composed of chips, or can include chips and other discrete devices.

[0144] The communication method provided in the embodiment of the present application will be described below in conjunction with the communication systems shown in Figures 4 to 6 above.

[0145] It should be noted that in the following embodiments of the present application, the message names, parameter names, or information names between network elements are only examples. In other embodiments, they may also be other names, and the method provided in the present application does not make specific limitations on this.

[0146] It is understood that in the embodiments of the present application, each network element may perform some or all of the steps in the embodiments of the present application. These steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations. In addition, the steps may be performed in a different order than those presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application need to be performed.

[0147] Figure 8 is a schematic diagram of an example of a communication method provided by an embodiment of the present application. The method is illustrated by taking the interaction between a first access network device and a second access network device as an example. Of course, the subject that executes the action of the first access network device in the method can also be a device / module of the first access network device, such as a chip, processor, or processing unit in the first access network device; the subject that executes the action of the second access network device in the method can also be a device / module in the second access network device, such as a chip, processor, or processing unit in the second access network device, etc. The embodiment of the present application does not make specific limitations on this. For example, as shown in Figure 8, method 800 includes:

[0148] Optionally, in S801, a first access network device sends first mobility information to a second access network device. Correspondingly, the second access network device receives the first mobility information from the first access network device.

[0149] In an embodiment of the present application, the first mobility information is predicted mobility information of a terminal device in multiple cells, where the multiple cells include cells corresponding to one or more access network devices, and the one or more access network devices include a second access network device. Optionally, the first mobility information is determined by the first access network device, or the first mobility information is determined by another access network device (for example, an access network device corresponding to a cell where the terminal device was previously located by the first access network device), which is not limited in this embodiment of the present application.

[0150] Optionally, the first mobility information may be carried in a switching request sent by the first access network device to the second access network device, or the first access network device may send the first mobility information to the second access network device via a separate message. This embodiment of the present application does not limit this.

[0151] In an embodiment of the present application, the first mobility information includes at least one of the following: a cell identifier corresponding to each of the multiple cells, or a dwell time of the terminal device in each cell. The cell identifier may be a CGI, an NCGI, or a PCI. Optionally, the first mobility information also includes identification information of an access network device corresponding to the cell, which is not limited in the embodiment of the present application. For example, taking the multiple cells as 6 cells as an example, the first mobility information may be as shown in Table 1 below.

[0152] Table 1

[0153] In an embodiment of the present application, the movement information of the terminal device in multiple cells may also be the information of the synchronization signal or physical broadcast channel block (synchronization signal / (physical broadcast channel, PBCH) block, SSB) passed by the terminal device, wherein the information of the SSB passed by the terminal device includes the identifier of each SSB passed by the terminal device and the residence time in each SSB, which is not limited in the embodiment of the present application.

[0154] In the embodiment of the present application, the cell corresponding to the access network device can be understood as the cell under which the access network device provides services. The cell corresponding to the access network device can be replaced by the cell under the access network device. This is explained here and will not be repeated below. Among them, one access network device can correspond to one cell or multiple cells, and the embodiment of the present application does not limit this.

[0155] Optionally, the number of access network devices corresponding to the multiple cells in the predicted mobile information of the terminal device is less than or equal to a first threshold, and / or the number of multiple cells in the predicted mobile information of the terminal device is less than or equal to a second threshold, that is, there is a limit on the number of predicted access network devices, and / or there is a limit on the number of predicted cells.

[0156] In a first possible implementation, the first access network device may send the first mobility information to each of the one or more second access network devices. Correspondingly, each of the one or more second access network devices receives the first mobility information from the first access network device. In this implementation, the first access network device sends the first mobility information to the access network devices corresponding to the multiple cells included in the first mobility information, and the one or more second access network devices are the second access network devices to which the predicted terminal devices switch in sequence. In the first possible implementation, the feedback of information between the access network devices corresponding to the first mobility information is not involved. The embodiment of the present application only describes the steps of one of the second access network devices, and will not be repeated in subsequent embodiments.

[0157] In a second possible implementation, the communication method provided in an embodiment of the present application may optionally further include: S802: the second access network device sends first mobility information to a third access network device. Accordingly, the third access network device receives the first mobility information from the second access network device. Specifically, the second access network device sends the predicted mobility information of cells corresponding to all access network devices subsequent to the first access network device to the third access network device.

[0158] In a third possible implementation, optionally, the communication method provided in the embodiment of the present application further includes: S803, the second access network device sends fourth mobility information to the third access network device. Accordingly, the third access network device receives the fourth mobility information from the second access network device. The one or more access network devices include a third access network device, and the third access network device is an access network device subsequent to the second access network device. The fourth mobility information includes the predicted mobility information of the terminal device in the cell corresponding to the third access network device, that is, the mobility information of the cell corresponding to the third access network device sent by the second access network device to the third access network device.

[0159] S810: A first access network device sends first configuration information to a second access network device. Correspondingly, the second access network device receives the first configuration information from the first access network device.

[0160] Optionally, the first configuration information and the first mobility information may be carried in the same message, or the first configuration information and the first mobility information may be carried in two different messages.

[0161] In an embodiment of the present application, the first configuration information is used to instruct the second access network device to send the first information to the first access network device.

[0162] In an embodiment of the present application, the first configuration information includes at least one of the following: a first data object, first duration information, a first conditional configuration, or a first identifier.

[0163] The first data object indicates that the first information includes data corresponding to the first data object. Exemplarily, the first data object includes at least one of the following: measurement information of the terminal device in the cell corresponding to the second access network device, actual movement information of the second access network device, coverage and capacity optimization (CCO) configuration information of the second access network device, indication information of whether the cell corresponding to the second access network device is turned off or on, or connection status information of the terminal device. Alternatively, the first data object may also include other data objects, which is not limited in this embodiment of the present application.

[0165] The first condition configuration is used to indicate the condition under which the second access network device sends the first information to the first access network device. In other words, the first condition configuration indicates that when the first condition is met, the second access network device sends the first information to the first access network device. Exemplarily, the first condition configuration is to send the first information to the first access network device when the terminal device performs cell switching, that is, the first condition is that the terminal device performs cell switching between multiple cells served by the second access network device. Exemplarily, the first condition of the cell corresponding to the access network device is configured to send the measurement information of the cell of the second terminal device to the first access network device when the change in the measurement information of the cell corresponding to the second access network device of the terminal device is greater than or equal to a threshold. For example, the first configuration information sent by the first access network device to the second access network device includes the measurement information of the cell corresponding to the first access network device and the third threshold. When the measurement information obtained by the terminal device measuring the cell corresponding to the second access network device is greater than or equal to the third threshold compared to the change in the measurement information of the terminal device in the cell corresponding to the first access network device, the second access network device sends the measurement information of the cell corresponding to the second access network device to the first access network device. For example, for the same cell, if the difference between the signal quality measured by the terminal device under the first access network device and the signal quality measured by the terminal device under the second access network device is greater than or equal to the third threshold, the second access network device sends the signal quality of the cell to the first access network device. For another example, if the difference between the cell measured by the terminal device under the second access network device and the cell measured by the terminal device under the first access network device is greater than or equal to the third threshold, the second access network device sends the measurement information of the second access network device to the first access network device (for example, the cells measured by the terminal device under the second access network device are cell 1, cell 2, and cell 3, and the cells measured by the terminal device under the first access network device are cell 3, cell 4, and cell 5, the difference is 2 cells, and the third threshold is 2).

Referring to the data collection process in Related Technology 4, the first configuration information sent by the first access network device to the second access network device may include the first identifier, and the first information sent by the second access network device to the first access network device also includes the first identifier. This allows the first access network device to learn that the first information is obtained based on the first configuration information request, enabling the data collection process to be associated.

[0167] Corresponding to the first possible implementation of S801 above, the first access network device may send the first configuration information to each of the one or more second access network devices. Accordingly, each of the one or more second access network devices receives the first configuration information from the first access network device. The first configuration information of each second access network device also includes an identifier of each second access network device.

[0168] Corresponding to the second possible implementation of S802 above, optionally, the communication method provided in the embodiment of the present application further includes: S811, the first access network device sends second configuration information to the second access network device.

The identifier of the third access network device is used to instruct the second access network device to forward the second configuration information. For the relevant description of other information in the second configuration information except the third access network device, please refer to the relevant description of the first configuration information, and the embodiments of the present application will not be repeated here.

The fourth configuration information differs from the second configuration information in that the fourth configuration information does not include the identifier of the third access network device, i.e., the second access network device does not need to carry the identifier of the third access network device when forwarding the second configuration information to the third access network device.

[0175] Alternatively, corresponding to the third possible implementation of S803 above, optionally, the communication method provided in this embodiment of the present application further includes: S813, the second access network device sends third configuration information to the third access network device.

The third identifier is determined by the second access network device. That is, after receiving the second configuration information from the first access network device, the second access network device can replace the second identifier with the third identifier corresponding to its own data collection process and then send the third configuration information to the third access network device. For a description of other information in the third configuration information other than the third identifier, refer to the description of the fourth configuration information and will not be repeated in this embodiment of the present application. Optionally, the first configuration information also includes second indication information. The second indication information indicates the validity period for the second access network device to send the first information to the first access network device. Exemplarily, when the validity period of the first information expires, the first access network device and / or the second access network device releases the interface between the first access network device and the second access network device.

[0177] Similarly, for the second configuration information, or the third configuration information, or the fourth configuration information, the second configuration information, or the third configuration information or the fourth configuration information may also include indication information indicating the effective duration of the corresponding interface, which will not be repeated in the embodiments of the present application.

[0178] As a possible implementation method, the first configuration information does not include the second indication information, and when the terminal device leaves the second access network device, the interface between the first access network device and the second access network device is released, or when the terminal device switches to the third access network device or leaves the third access network device, the terminal device sends indication information to the first access network device or the second access network device, instructing the first access network device or the second access network device to release the interface between the first access network device and the second access network device. The third access network device is the access network device where the terminal device is actually located after leaving the second access network device (for example, the third access network device is not included in the predicted one or more access network devices, but the terminal device actually switches to the third access network device, that is, the prediction is inaccurate, or the third access network device is included in the predicted one or more access network devices, and the terminal device actually switches to the third access network device, that is, the prediction is accurate). This embodiment of the present application does not limit this.

[0179] Similarly, the second configuration information, or the third configuration information, or the fourth configuration information may not include indication information indicating the effective duration of the corresponding interface. Please refer to the description that the second indication information is not included in the above-mentioned first configuration information, and the embodiments of the present application will not be repeated here.

[0180] Optionally, the first configuration information further includes third indication information, wherein the third indication information is used to instruct the second access network device to determine second mobility information, wherein the second mobility information is the updated first mobility information.

[0181] Similarly, the second configuration information, or the third configuration information, or the fourth configuration information also includes indication information for instructing the third access network device to determine the third mobile information.

[0182] S820: The second access network device sends first information to the first access network device. Correspondingly, the first access network device receives the first information from the second access network device.

[0183] In an embodiment of the present application, before the second access network device sends the first information to the first access network device, the communication method provided in the embodiment of the present application also includes: the terminal device switches from the cell corresponding to the first access network device to the cell corresponding to the second access network device.

[0184] In the embodiment of the present application, the first information is used to determine the second mobility information, wherein the second mobility information may be determined by the first access network device, or the second mobility information may be determined by the second access network device, which will be described below respectively.

[0185] In one possible implementation, the first information includes at least one of the following: measurement information of the terminal device in the cell corresponding to the second access network device, actual movement information of the second access network device, CCO information of the second access network device, indication information of whether the cell corresponding to the second access network device is turned off or on, or connection status information of the terminal device.

[0186] In this implementation, the first access network device has the ability to predict the mobility information of the terminal device. For example, the first access network device includes an AI module that can determine the second mobility information based on the first information sent by the second access network device. In another example, the first access network device requests AI-related services from the RIC and can send the first information to the RIC. The RIC determines the second mobility information based on the first information and sends it to the first access network device.

[0188] Exemplarily, the actual mobility information of the second access network device may include the mobility information of the cell most recently visited by the terminal device. For details, please refer to the relevant content of the historical mobility information of the terminal device in the related technology three, and the embodiments of this application will not be repeated here.

[0189] Exemplarily, the CCO information of the second access network device may include cell coverage adjustment information.

[0190] Exemplarily, the indication information of whether the cell corresponding to the second access network device is turned off or on may include a turn-off indication of the cell corresponding to the second access network device, or may include a turn-on indication of the cell corresponding to the second access network device.

[0191] Exemplarily, the connection state of the terminal device may include an idle state, or an inactive state, etc. For example, the second access network device periodically sends first information to the first access network device. When the terminal device enters the idle state or the inactive state, since there is no available measurement information to report, the connection state of the terminal device may be sent to the first access network device as an idle state or an inactive state.

[0192] Optionally, the communication method provided in an embodiment of the present application further includes: the first access network device determining second mobility information based on the first information. The first access network device sends the second mobility information to the second access network device. In response, the second access network device receives the second mobility information from the first access network device. In this solution, after determining the second mobility information, the first access network device may send the second mobility information to the second access network device, so that the second access network device can adjust subsequent resource configurations.

[0193] Optionally, the second mobility information determined by the first access network device may include mobility information corresponding to at least one first cell, where the mobility information corresponding to the at least one first cell includes mobility information of cells that the terminal device has resided in after the first access network device was connected and predicted mobility information of the terminal device after the current cell in which it resides. This solution can ensure that the second mobility information includes both the historical mobility information of the terminal device and predicted mobility information of the terminal device in multiple cells, making it more comprehensive.

The second mobile information includes the historical mobile information of the terminal device in cells 2 and 3, and also includes the predicted mobile information of the terminal device in cells 4 to 6 and cells 9 to 11, where cell 3 is the cell where the terminal device currently resides, and cells 4 to 6 and cells 9 to 11 are the predicted cells after cell 3.

[0195] Optionally, the second mobility information determined by the first access network device may include mobility information corresponding to at least one second cell, wherein the mobility information corresponding to the at least one second cell includes predicted mobility information of a cell subsequent to the cell in which the terminal device is currently stationed. This solution can save signaling overhead.

[0196] For example, the first mobile information includes the predicted mobile information of the terminal device in cells 1 to 8, where cell 1 is the cell under the first access network device, and cells 2 and 3 are the cells where the terminal device resides in sequence after cell 1. The terminal device currently resides in cell 3. The second mobile information includes the predicted mobile information of the terminal device in cells 4 to 6 and cells 9 to 11.

[0197] Optionally, the second mobility information determined by the first access network device may include an identifier of a third cell and mobility information corresponding to at least one fourth cell, wherein the mobility information corresponding to the at least one fourth cell includes predicted mobility information of a cell subsequent to the third cell for the terminal device, and the identifier of the third cell is used to indicate that the first mobility information and the second mobility information corresponding to a cell prior to the third cell are the same. Compared to a solution in which the second mobility information includes mobility information of at least one second cell, this solution can further reduce signaling overhead.

[0198] For example, the first mobile information includes the predicted mobile information of the terminal device in cells 1 to 8, where cell 1 is the cell under the first access network device, and cells 2 and 3 are the cells where the terminal device resides in sequence after cell 1. The terminal device currently resides in cell 3. The second mobile information includes the predicted mobile information of the terminal device in cells 9 to 11 and the identifier of cell 6.

[0206] Optionally, the first access network device may retrain the AI ​​model based on the second mobility information included in the first information sent by the second access network device to improve the accuracy of predicting the mobility information of the terminal device.

[0207] Alternatively, as a possible implementation method, the second access network device may not send the first information to the first access network device, and the second access network device may send a failure indication to the first access network device to indicate that the second access network device cannot send the first information to the first access network device.

For example, the second access network device determines not to determine the second mobility information based on its own capabilities or computing resources.

[0212] Optionally, the second access network device can send indication information to the first access network device, indicating that the second access network device can predict the mobility information of the terminal device.
