[0051] In order to better understand the solution provided by this application, the following is an introduction to the professional terms and technical terms involved in this application:

[0052] 1. Models, Model Lifecycle Management, and Model Lifecycle Management Information

[0053] The model is an AI model or an AIML model. The model can be used to implement multiple functions. In the embodiment of the present application, the model can be used to implement a communication function. The communication function may include, but is not limited to, at least one of the following functions:

[0054] Channel State Information (CSI) compression feedback;

[0055] Channel state information prediction;

[0056] Beam management;

[0057] position.

[0058] Optionally, the positioning may include direct positioning, indirect positioning, etc.

[0059] Model lifecycle management refers to the lifecycle management of a model. The functions that lifecycle management implements on a model can be regarded as functions of lifecycle management. Optionally, the lifecycle management can implement at least one of the following functions on the model:

[0060] Data collection;

[0061] Data reporting;

[0062] Model training;

[0063] Model update;

[0064] Federated learning;

[0065] Distributed learning;

[0066] Dual-end learning;

[0067] Base station training;

[0068] Core network training;

[0069] Model Identification;

[0070] Model transfer / delivery

[0071] Model inference;

[0072] Model monitoring;

[0073] Model selection

[0074] Model activation / deactivation

[0075] Model switching

[0076] Model fallback.

[0077] Optionally, the data reporting method may be SDT (Small Data Transmission), connection state reporting, or other reporting methods, which are not limited here. Federated learning may be core network federated learning and / or access network federated learning, or other federated learning, which are not limited here.

[0078] Different model lifecycle processes correspond to different model functions, and / or different model lifecycle management processes correspond to different lifecycle management functions. For example, model lifecycle management process 1 is a lifecycle management process for model training of the positioning function model, model lifecycle management process 2 refers to a lifecycle management process for model reasoning of the channel state information prediction function, model lifecycle management process 3 is a lifecycle management process for model monitoring of the positioning function model, and model lifecycle management 4 is a lifecycle management process for model training of the channel state information compression feedback function model. Among them, the model lifecycle management process 1 and the model lifecycle management process 2 correspond to different model functions and lifecycle management functions, and the two are different model lifecycle processes; the model lifecycle management process 1 and the model lifecycle management process 3 correspond to the same model functions, but the corresponding lifecycle management functions are different, and the two are different model lifecycle management processes; the model lifecycle management process 1 and the model lifecycle management process 4 correspond to different model functions, but the corresponding lifecycle management functions are the same, and the two are different model lifecycle management processes.

[0079] The model lifecycle management information is used to indicate participation in the model lifecycle management process. For example, the model lifecycle management information is used to indicate that the terminal device indicated by the terminal device identification information participates in the model lifecycle management process. Optionally, the model lifecycle management information may include but is not limited to at least one of the following information:

[0080] Model identification information,

[0081] The model's functionality information,

[0082] Functional information for lifecycle management.

[0083] The model identification information is used to identify the model, and different models have different corresponding model identification information. Optionally, the model identification information may be a model identifier (Model ID)

[0084] The function information of the model is used to indicate the function of the model, and the function information of the lifecycle management is used to indicate the function of the lifecycle management.

[0085] 2. Radio Resource Control: Non-Connected and Connected States

[0086] The radio resource control non-connected state is also called the non-connected state. The radio resource control non-connected state includes the radio resource control idle (RRC Idle) state and the radio resource control inactive (RRC Inactive) state.

[0087] The radio resource control idle state is also called the idle state. In the radio resource control idle state, the terminal device has no dedicated radio resource control (RRC) connection with the access network device.

[0088] The radio resource control inactive state is also called the inactive state. In the radio resource control inactive state, the dedicated RRC connection between the terminal device and the access network device is suspended.

[0089] Radio Resource Control Connected (RRC Connected), also known as Connected state. In the RRC Connected state, the terminal device has a dedicated RRC connection with the access network device, and the RRC connection is activated. The terminal device can enter the RRC Connected state by initiating a Random Access (RA) process.

[0090] 3. Paging, Paging Messages and Paging Occasion (PO)

[0091] Paging technology is an important technology in wireless communication systems. Access network equipment can find terminal equipment through paging and initiate services to the terminal equipment.

[0092] A paging message is a message used by an access network device to page a terminal device. In the embodiment of the present application, the paging message may include but is not limited to at least one of the following information:

[0093] First information,

[0094] Second paging group information,

[0095] Model lifecycle management information,

[0096] Paging cause information,

[0097] NeedConnectedState information,

[0098] Emergency information,

[0099] Response time (ResponseTime) information;

[0100] Optionally, the paging reason information may be used to indicate a paging reason. In an embodiment of the present application, the paging reason information indicates that the paging reason is model lifecycle management.

[0101] Optionally, the connection-required state information is used to indicate whether the terminal device needs to switch to a connected state.

[0102] Optionally, the emergency information is used to indicate whether the model lifecycle management process is urgent.

[0103] Optionally, the response time information is used to indicate the time for executing the response processing. The terminal device is allowed to complete the response within the response time indicated by the response time information.

[0104] For descriptions of the first information, the second paging group information, and the model lifecycle management information, please refer to the descriptions of other terms and technical terms mentioned above or subsequently, which will not be described in detail here.

[0105] The location of the paging message is called the paging opportunity. Among them, on the access network device side, the paging opportunity can be the opportunity to send a paging message; on the terminal device side, the paging opportunity can be the opportunity to receive a paging message. The access network device can calculate the paging opportunity according to the instructions of the core network device and / or its own policy, so as to send a paging message at the paging opportunity. The terminal device can calculate its own corresponding paging opportunity based on relevant parameters (such as its own identification number information and paging-related parameters provided by the system message, etc.) so as to receive the paging message at the corresponding paging opportunity. When the terminal device is in a non-connected state (including an idle state and an inactive state), it will periodically receive paging.

[0106] 4. Paging timer and paging times

[0107] The access network device sets a paging timer, which is used to time the duration of each paging process. Each paging process refers to the process of the access network device sending a paging message and receiving a paging response message from the terminal device in response to the paging message. After successfully receiving the paging message, the terminal device will send a paging response message to the access network device.

[0108] When the access network device sends a paging message, it starts the paging timer. If it receives a paging response message from the terminal device, the access network device stops the timer. Each action of sending a paging message corresponds to an action of starting the paging timer. If the paging timer expires, the access network device determines that the paging message has not been successfully delivered to the terminal device.

[0109] Optionally, the access network device sets a paging number, and the paging number is used to accumulate the number of times the paging timer expires. If the paging timer expires, the paging number is incremented by 1.

[0110] 5. Paging Group and Paging Group Information

[0111] The core network device and / or the access network device can divide the terminal devices into corresponding paging groups according to the model lifecycle management process and / or other services, and instruct one or more terminal devices contained in the paging group to participate in the model lifecycle management process and / or other services through the paging group. Among them, other services refer to services other than the model lifecycle management process, which may be referred to as services below. Optionally, other services may be, for example, MBS (Multicast and Broadcast Service) or other types of services, and other services are not limited here. The following only takes the core network device as an example to illustrate the method of configuring the paging group:

[0112] The core network device determines the terminal devices participating in the model lifecycle management process based on the capabilities of the terminal devices, and divides the terminal devices participating in the model lifecycle management process into a first paging group, that is, the first paging group includes the terminal devices participating in the model lifecycle management process.

[0113] Optionally, the core network device further determines the terminal devices participating in other services according to the capabilities of the terminal devices, and divides the terminal devices participating in other services into a second paging group, that is, the second paging group includes the terminal devices participating in other services.

[0114] Optionally, the number of the first paging groups may be one or more. Optionally, different first paging groups include terminal devices participating in different model lifecycle management processes.

[0115] Optionally, the number of the second paging groups may be one or more. Optionally, terminal devices participating in the same service are divided into the same second paging group, and different second paging groups include terminal devices participating in different services.

[0116] Optionally, the upper limit value of the total number of one or more paging groups divided by the core network device is a specific value, that is, the upper limit value of the number of paging groups of the first paging group and the second paging group is a specific value. For example, the upper limit value of the number of paging groups of the first paging group and the second paging group is a first specific value, and the first specific value can be, for example, 32, 48, 64, 128, 256, etc., and the specific value of the first specific value is not limited here.

[0117] Optionally, the upper limit of the number of paging groups of the first paging group may also be a specific value, such as a second specific value. Optionally, the second specific value may be, for example, 32, 48, 64, 128, 256, etc., and the specific value of the second specific value is not limited herein.

[0118] Optionally, the upper limit of the number of paging groups of the second paging group may also be a specific value, such as a third specific value. Optionally, the third specific value may be, for example, 32, 48, 64, 128, 256, etc., and the specific value of the third specific value is not limited herein.

[0119] Optionally, the first specific value, the second specific value, and the third specific value may be completely the same, partially the same, or completely different, which is not limited here.

[0120] Optionally, the same paging group includes one or more terminal devices. The terminal devices included in different paging groups may be the same, partially the same, or completely different.

[0121] It should be noted that the access network device can execute the same or similar method of configuring the paging group as the core network device, that is, the action of dividing the paging group, which will not be elaborated here.

[0122] In the embodiment of the present application, the paging group information is used to indicate the paging group. Optionally, the first paging group information is used to indicate the first paging group. Optionally, the second paging group information is used to indicate the second paging group. It should be noted that the paging group information indicates the paging group, which does not mean that the paging group information includes the information of the terminal devices included in the paging group, for example, the terminal device identification information.

[0123] 6. Information of terminal devices involved in the model lifecycle management process

[0124] The information of the terminal device participating in the model lifecycle management process can also be referred to as the terminal device information. The terminal device information can be used to determine the timing of sending a paging message, i.e., the paging timing. Optionally, the terminal device information can include but is not limited to at least one of the following information:

[0125] Model lifecycle management information,

[0126] Paging area information,

[0127] Terminal device identification information,

[0128] Paging discontinuous reception information,

[0129] Paging reason information,

[0130] Requires connection status information,

[0131] Emergency information,

[0132] response time information;

[0133] The paging reason information indicates that the paging reason is model lifecycle management.

[0134] Optionally, the paging area information may be used to indicate the range of the paging area. Optionally, the paging area information may be presented in the form of area information and / or location information.

[0135] Optionally, the paging discontinuous reception information may be used by the access network device to determine a paging opportunity.

[0136] For other information included in the information of the terminal device, please refer to the description of other terms and technical terms mentioned above or later, which will not be described in detail here.

[0137] VII. Paging Records and Paging Record Information

[0138] The paging record is used to record information related to paging. The paging record information is used to indicate the paging record, and optionally, the paging record information includes information recorded in the paging record.

[0139] In the embodiment of the present application, the paging record information includes terminal device identification information and model lifecycle management information. The model lifecycle management information in the paging record information is used to indicate that the terminal device identified by the terminal device identification information in the paging record information participates in the model lifecycle management process.

[0140] Optionally, the paging record information may exist in a list form. Optionally, the paging record information may include one or more paging records.

[0141] Optionally, the paging record information may include paging records of different versions. The terminal device identification information and the model lifecycle management information may be recorded in the same version of the paging record, or in different versions of the paging record. For example, in the list corresponding to the paging record information, the paging record used to record the model lifecycle management information may be located after the paging record used to record the terminal device identification information, to indicate that the model lifecycle management information acts on the terminal device identification information in the paging record that precedes the paging record in which it is located, that is, the model lifecycle management information is used to indicate that the terminal device identified by the terminal device identification information participates in the model lifecycle management process.

[0142] Optionally, the terminal device identification information is recorded in the paging record of the existing version. One or more new versions of paging records are added to the existing version, and the new versions are higher than the existing versions. The model lifecycle management information is recorded in the paging records of the new versions.

[0143] Optionally, the terminal device can parse the corresponding version of the paging record for forward compatibility based on the version of the paging record it supports, so as to determine the terminal devices participating in the model lifecycle management process based on the terminal device identification information and / or model lifecycle management information obtained by the parsing.

[0144] For example, the terminal device identification information is recorded in the R15 version of the paging record, and the model lifecycle management information is recorded in the newly added R17 version of the paging record. If the terminal device supports parsing the R15 version of the paging record, the terminal device can parse the R15 version of the paging record to obtain the terminal device identification information carried by the paging record information, but cannot parse the R17 version of the paging record to obtain the model lifecycle management information carried by the paging record information.

[0145] For example, if the terminal device supports parsing R17 version paging records, it can parse the R17 version paging records to obtain the model lifecycle management information carried by the paging record information, and can parse the R15 version paging records to obtain the terminal device identification information carried by the paging incentive information. Based on the parsed model lifecycle management information and terminal device identification information, it is determined that the terminal device identified by the terminal device identification information is a terminal device that indicates participating in the model lifecycle management process.

[0146] Optionally, the terminal device identification information included in the paging record information may be one or more terminal device identification information, and the model lifecycle management information included in the paging record information may indicate one or more model lifecycle management processes involved.

[0147] 8. First Information

[0148] The first information is included in the paging message and is used to indicate a terminal device participating in the model lifecycle management process, where the terminal device is in a radio resource control non-connected state.

[0149] The information indicated by the first information includes the model lifecycle management process involved and the terminal device involved in the process. The first information indicates that the model lifecycle management process involved can be one or more.

[0214] Among them, the first information is used to indicate a terminal device participating in the model lifecycle management process, and the terminal device is in a wireless resource control non-connected state.

[0215] Optionally, the access network device sends the paging message at the timing determined in step 204 .

[0216] Correspondingly, the terminal device receives the paging message from the access network device.

[0217] Optionally, a terminal device in a radio resource control non-connected state monitors a paging channel and receives a paging message from an access network device.

[0218] Optionally, the terminal device receives the paging message at the paging opportunity determined by itself. If the paging opportunity determined by the terminal device itself is the same as or corresponds to the opportunity determined by the access network device in step 204, the terminal device can receive the paging message, otherwise, the terminal device cannot receive the paging message.

[0219] In an optional implementation manner, the first paging group includes terminal devices participating in the model lifecycle management process. The access network device adds paging group information to the paging message, and the added paging group information may include the first paging group information, so that the terminal device can parse the paging message and obtain the first paging group information.

[0220] Optionally, the paging group information added by the access network device to the paging message may further include second paging group information, where the second paging group information is used to indicate a second paging group, and the second paging group includes terminal devices participating in other services.

[0224] In an optional implementation, the access network device controls and adjusts the process of the access network device paging the terminal device by setting a paging timer and / or the number of paging times. Optionally, the paging timer corresponding to different model lifecycle management processes has different timing durations, and / or the upper limit of the number of paging times corresponding to different model lifecycle management processes has different upper limits, thereby meeting the needs of different model lifecycle management processes and ensuring that the access network device pages the terminal device in a timely manner.

[0225] The paging timer may be used to time the duration of each paging process; and the number of paging times may be used to accumulate the number of times the paging timer expires.

[0226] Optionally, when the access network device sends a paging message to the terminal device, the access network device starts a paging timer for timing. Optionally, when the paging timer expires, the number of paging times is incremented by 1. In the embodiment of the present application, the number of paging times can be used to count: the number of times the access network device sends a paging message for this model lifecycle management process.

[0227] Optionally, the access network device may adjust the time interval for paging the terminal device through a paging timer. Optionally, the access network device may adjust the time interval for paging the terminal device through at least one of the following three methods to meet the requirements of different model lifecycle management processes:

[0228] Method 1: Increase the timing duration of the paging timer.

[0229] Method 1 can increase the time interval for the access network device to send paging messages and reduce the frequency of sending paging messages.

[0230] Method 2: After the paging timer expires, wait for a certain period of time and then restart the paging timer.

[0231] Among them, after the paging timer expires and before the paging timer is restarted, the access network device stops sending paging messages and receiving paging response information. In the case of the paging timer restart, the access network device sends a paging message. Starting a paging timer corresponds to an action of sending a paging message.

[0232] Optionally, the waiting time in method 2 may be the time specified by the protocol, or the time coordinated between the access network device and the core network device, or the time obtained by other means, which is not limited here.

[0233] Mode 3: After each paging count is accumulated, the timing duration of the restarted paging timer can be adjusted so that the adjusted timing duration is different from the timing duration of the paging timer started last time.

[0234] For example, after the paging timer started last time expires, the timing duration of the restarted paging timer is longer than the timing duration of the paging timer started last time.

[0235] The cumulative increase in the number of paging times and the expiration of the paging timer started last time both mean that the access network device failed to paging within the time duration of the paging timer started last time. Increasing the time duration of the restarted paging timer increases the time for the access network device to perform paging again, thereby increasing the success rate of paging to the terminal device.

[0236] 206. The terminal device participates in the model lifecycle management process according to the paging message.

[0237] In an optional implementation manner, the terminal device participates in the model lifecycle management process according to the paging message, including: if the terminal device determines that it belongs to the first paging group, it participates in the model lifecycle management process.

[0238] The terminal device parses the paging message to obtain the first paging group information; the terminal device determines, based on the first paging group information, that the paging group to which the terminal device belongs includes the first paging group, and then determines that the terminal device belongs to the first paging group.

[0239] Among them, the terminal device can belong to one or more paging groups.

[0240] In an optional implementation, the terminal device parses the paging message and obtains the second paging group information; the terminal device determines, based on the second paging group information, that the paging group to which the terminal device belongs includes the second paging group, and then determines that the terminal device belongs to the second paging group. If the terminal device determines that it belongs to the second paging group, it participates in other services indicated by the second paging group.

[0241] In an optional implementation manner, the participating in the model lifecycle management process includes at least one of the following steps:

[0242] The terminal device submits the model lifecycle management information to an upper layer;

[0243] The terminal device initiates random access, enters the connected state and participates in the model lifecycle management process.

[0244] Optionally, after the terminal device submits the model lifecycle management information to the upper layer of the terminal device, the upper layer controls the terminal device to participate in the model lifecycle management process based on the model lifecycle management information. For example, the upper layer determines whether the terminal device participates in the model lifecycle management process based on the model lifecycle management information, and / or determines the time when the terminal device starts participating in the model lifecycle management process. Optionally, the upper layer can determine that the terminal device starts participating in the model lifecycle management process immediately, or can also determine that the terminal device starts participating in the model lifecycle management process after waiting for a period of time.

[0245] Optionally, the terminal device initiates random access, enters a connected state and participates in the model lifecycle management process, including: the terminal device initiates random access according to the paging message, enters a connected state and participates in the model lifecycle management process.

[0246] Optionally, the terminal device may determine whether the terminal device needs to enter a connected state based on the connection state information required in the paging message; if it is determined that the terminal device needs to enter a connected state, random access is initiated to enter the connected state and participate in the model lifecycle management process.

[0247] Optionally, the terminal device can determine whether the model lifecycle management process is urgent based on the emergency information in the paging message; if it is determined that the model lifecycle management process is urgent, random access is initiated, and the connected state is entered to participate in the model lifecycle management process; if it is determined that the model lifecycle management process is not urgent, random access can be initiated after waiting for a period of time, and the connected state can be entered to participate in the model lifecycle management process.

[0248] Optionally, the terminal device may respond within the response time indicated by the response time information according to the response time information in the paging message, for example, initiate random access within the response time, enter the connected state and participate in the model lifecycle management process.

[0249] It should be noted that the terminal device executing step 206 is a terminal device that has started participating in the model lifecycle management process, and the terminal device here can be regarded as a terminal device that is a potential or candidate to participate in the model lifecycle management process. After the terminal device starts participating in the model lifecycle management process according to the paging message, the access network device and / or the core network device will further determine whether the terminal device can ultimately participate in the model lifecycle management process, that is, determine whether the terminal device is a terminal device that ultimately participates in the model lifecycle management process.

[0250] For example, after starting to execute step 206, the terminal device enters a connected state and reports its own dynamic capabilities to the access network device. The access network device determines whether the terminal device can continue to participate in the subsequent model lifecycle management process based on the dynamic capabilities reported by the terminal device. If so, the terminal device is not processed, or the terminal device is instructed to continue to participate in the model lifecycle management process. If not, the terminal device is instructed to stop participating in the model lifecycle management process. For another example, the access network device may further report the dynamic capabilities of the terminal device to the core network device, and the core network device completes the above judgment process, and instructs the terminal device to continue to participate in the model lifecycle management process through the access network device, or, such as through a non-access layer message, instructs the terminal device to continue to participate in the model lifecycle management process, or does not process the terminal device. For another example, the access network device may negotiate with the core network device to perform the above judgment process and the instruction process to the terminal device.

[0325] Optionally, after the terminal device submits the model lifecycle management information to the upper layer of the terminal device, the upper layer controls the terminal device to participate in the model lifecycle management process based on the model lifecycle management information. For example, the upper layer determines whether the terminal device participates in the model lifecycle management process based on the model lifecycle management information, and / or determines the time when the terminal device starts participating in the model lifecycle management process. Optionally, the upper layer can determine that the terminal device starts participating in the model lifecycle management process immediately, or can also determine that the terminal device starts participating in the model lifecycle management process after waiting for a period of time.
