Description

Function or model identification method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] The 3GPP R18 artificial intelligence / machine learning (AI / ML) project defines multiple scenarios or sub-scenarios, such as channel state indicator (CSI enhancement) (which may also include at least one sub-scenarios of CSI compression and CSI predication), beam management, positioning, or other scenarios. In some scenarios or sub-scenarios, an AI model may also correspond to multiple AI functions. The 3GPP R19 AI / ML-based mobility project also defines scenarios or sub-scenarios, such as normal switching, conditional switching, L1 / L2 triggered mobility (LTM), or other scenarios.

[0003] Different scenarios or sub-scenarios can correspond to one or more features / feature groups. Applying AI / ML to the above feature / feature group is called an AI / ML-based / enabled feature / feature group. An AI / ML-based / enabled feature / feature group can correspond to one or more AI functions and / or one or more AI models. An AI function can correspond to one or more AI models. A function refers to the configuration of an enabled AI / ML-based / enabled feature / feature group. The possible logic is shown in Figure 1.

[0004] AI models can be deployed on terminal devices. For example, a one-sided model deployed on a terminal device is called a UE-side model. A sub-model in a two-sided or multi-sided model can be deployed on a terminal device and is called the UE-part of a two-sided or multi-sided model.

[0005] AI models can be deployed on network devices. For example, a one-sided model deployed on a network device is called an NW-side model. A sub-model within a two-sided or multi-sided model can also be deployed on a network device and is called the NW-part of the two-sided or multi-sided model.

[0006] After the model is deployed or the model corresponding to the function is deployed (taking the deployment of UE-side model on terminal devices as an example), the function / model control device (such as a base station) and the function / model reasoning device (such as a terminal device) need to synchronize their understanding of the function / model and / or function / model related information, so the function / model identification mechanism needs to be considered.

[0007] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0041] In the above scenario, the network device may include at least one of a core network device, a third-party application device, an operation administration and maintenance (OAM), and an access network device.

[0042] The core network device may refer to a device in the core network (CN) that provides service support for the terminal device. As some examples, the core network device may be at least one of the following: a mobility and management entity (MME), an access and mobility management function (AMF) entity, a session management function (SMF) entity, a user plane function (UPF) entity, a location management function (LMF) entity, and the like, which are not listed here one by one. Among them, the AMF entity may be responsible for the access management and mobility management of the terminal, the SMF entity may be responsible for session management, such as the establishment of a user session, and the UPF entity may be a functional entity of the user plane, mainly responsible for connecting to the external network. The LMF entity may manage the overall coordination and scheduling of resources required for the location of the terminal device registered with the core network device or accessing the core network device. It should be noted that in the embodiment of the present application, the entity may also be referred to as a network element or a functional entity, such as the AMF entity may also be referred to as an AMF network element or an AMF functional entity, and so on.

[0043] The third-party application device can be an OTT service (over the top server) or other third-party device.

[0044] OAM is a network device that performs operations, management, and maintenance on the network according to the actual needs of the operator's network operations.

[0045] The access network device is an access device that the terminal device uses to access the communication system wirelessly. The access network device can be a base station (BS), an evolved NodeB (eNodeB), a transmission reception point (TRP), a base station (next generation NodeB, gNB) in the fifth generation (5G) mobile communication system, a base station in the sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The access network device can also be a module or unit that completes part of the functions of the base station. For example, it can be at least one of the following modules or units: a centralized unit (CU), a distributed unit (DU), a centralized unit control plane (CU control plane, CU-CP), a centralized unit user plane (CU user plane, CU-CP), an integrated access backhaul (IAB) or other modules or units. The embodiments of the present application do not limit the specific technology and / or specific device form adopted by the access network device. The access network equipment can be deployed on land, including indoors / outdoors, and can be handheld or vehicle-mounted; it can also be deployed on the water, on an airplane, on a balloon or on a satellite; the access network equipment can be deployed in a fixed location or on a mobile carrier, and the embodiments of the present application do not limit this.

A terminal device can also be referred to as a terminal, mobile station, or mobile terminal. A terminal device can be a mobile phone, tablet, or other device with wireless intelligent transceiver capabilities.

[0047] In the above scenarios, access network devices and terminal devices, and terminal devices and terminal devices can communicate via licensed spectrum, unlicensed spectrum, or both. The embodiments of this application do not limit the spectrum resources used for wireless communications.

[0048] In the following description of this application, artificial intelligence (AI) may also be referred to as artificial intelligence / machine learning (AI / ML) or machine learning ML. These terms are interchangeable. For example, "AI-based feature or feature group" and "AI- or ML-based feature or feature group" have the same meaning, and their English equivalents can be AI / ML-based feature / FG. " / " represents "or."

[0049] The following describes embodiments of the present application with reference to the accompanying drawings and detailed descriptions. For ease of description, the following description uses a base station as an example of an access network device. In the following description, "if," "under the circumstances," and "when" can be used interchangeably to avoid confusion.

[0050] The inventors believe that the local function / model identification process requires signaling interaction between the terminal device and the serving cell. If the terminal device changes its serving cell, the local function / model identification information becomes invalid after local function / model identification. The terminal device needs to re-initiate the local function / process with the new serving cell. Frequent local function / model identification processes will result in a large amount of air interface signaling overhead. To address the above issues, the present application proposes a function / model identification method, which is described below in conjunction with the embodiments.

[0051] Embodiments of the first aspect

[0052] An embodiment of the present application provides a function / model identification method, which is described from the perspective of a terminal device.

[0053] FIG2 is a schematic diagram of a function / model identification method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0054] 201: The terminal device sends a function / model identification request message to a first network device to which a first cell belongs. The function / model identification request message includes function / model configuration information of an AI function / AI model. The function / model identification request message is used to request the first network device to allocate local function / model identification information for the AI ​​function / AI model.

[0055] 202: The terminal device receives the function / model identification response message sent by the first network device.

[0056] It is worth noting that FIG2 above only schematically illustrates an embodiment of the present application, and the present application is not limited thereto. For example, other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG2 above.

[0057] This embodiment defines a process for local function / model identification, enabling terminal devices and network devices to manage functions / models based on local function / model identification information. In this embodiment, local function / model identification between the terminal device and the network device is valid only within the current serving cell. Maintenance of local function / model identification information by the terminal device is relatively simple.

[0058] In some embodiments, the AI ​​model can be configured on the terminal device side and / or the first network device side, or the model corresponding to the AI ​​function can be configured on the terminal device side and / or the first network device side. The function / model configuration information is used to indicate the identification information of the AI ​​function / AI model.

[0059] In some embodiments, during the model identification process, the model configuration information includes at least one of the following: model description information, model input information, model output information, model function information, scenario / configuration information required for model operation, model source information, or other model configuration information. The model description information is used to describe the model's parameters; optionally, the model can be uniquely identified based on the model parameter description information. The following provides examples of each of the above information.

[0060] Model description information: This information is used to describe the parameters of the AI ​​model. This information uniquely identifies the model, or in other words, uniquely identifies the model itself. The model description information includes at least one of the following: model architecture information, model layer parameters, the number of neurons in each layer, the weight of at least one neuron, the mapping relationship between neurons in different layers, or other model description information.

[0061] --Model input information: used to indicate the input information required for model reasoning, and / or the range of input information. For example, the model input information may indicate that the input information required for model reasoning is the measured value before the reasoning moment, or the maximum or minimum N measured values ​​before the reasoning result. And / or, the model input information may indicate that the physical quantity type of the input information required for model reasoning is the Reference Signal Receiving Power (RSRP) or the Signal to Interference plus Noise Ratio (SINR). And / or, the model input information may indicate that the dimension of the input information required for model reasoning is 24 or 48, etc., which will not be listed one by one here.

[0062] --Model output information: used to indicate the output information required for model reasoning, and / or the range of output information. For example, the model output information may indicate that the output information required for model reasoning is the measured value before the reasoning moment, or the maximum or minimum N measured values ​​before the reasoning result. And / or, the model output information may indicate that the physical quantity type of the output information of the model reasoning is the Reference Signal Receiving Power (RSRP) or the Signal to Interference plus Noise Ratio (SINR). And / or, the model output information may indicate that the dimension of the output information of the model reasoning is 96, etc., which will not be listed one by one here.

[0063] --Function information to which the model belongs: used to indicate the function type to which the model belongs, for example, used to indicate the functionality information corresponding to the model; the function can be indicated by the function identification information. The function identification information can be an index, an identifier, a name, or other information. The function type can be channel state indicator (CSI) enhancement (which can also include CSI compression, at least one sub-scenario of CSI prediction), beam management, positioning, normal switching, conditional switching, layer-triggered mobility (L1 / L2 triggered mobility, LTM), or other functions.

[0064] --Scenario / configuration information required for model operation (activation), used to indicate the scenario / configuration information of terminal devices and / or network devices that can achieve better performance by activating the model: including required scenario / configuration information on the terminal device side and / or the network device side; for example, storage resource information, computing resource information, power information, operating platform information, or other information of the model inference device. The terminal device configuration information may include at least one of the following: terminal device speed information, terminal device computing speed information, the channel model between the terminal device and the network device (e.g., line of sight (LOS) model or non-line of sight (NLOS) model), and other configuration information. The configuration information of the network device may include at least one of the following information: antenna configuration of the network device (such as tilt information under the antenna, the number of antennas, configuration information of analog antennas, digital antennas, physical antennas, etc.), beam configuration of the network device (such as beam width information, number of beams, beam scanning information and other configuration information), coverage configuration of the network device (such as frequency information, coverage range information, indoor, outdoor and other configuration information), status information of the network device (such as whether network energy saving is enabled for capacity stations and coverage stations, network energy saving configuration information, etc.), and other configuration information.

[0065] --Model source information: used to indicate the node information of the model, or used to indicate the device ownership information of the model. For example, the source information of the model includes at least one of the terminal device manufacturer information, chip manufacturer information, network device manufacturer information, and operator information.

[0066] In addition, the model configuration information may also include model format information, model language information, etc., which will not be listed one by one here.

[0067] As an example, in the function identification process, function configuration information is used to indicate the identification information of the function, or the identification information of the AI ​​model deployed under the function. This function configuration information includes at least one of the following information: model description information, function / model input information, function / model output information, function information to which the model belongs, scenario / configuration information required for the function / model to run, model source information, or other function configuration information. Examples are not given here one by one.

[0068] In some embodiments, the function / model identification request message is used to request the first network device to which the first cell belongs to allocate local function / model identification information for the AI ​​function / AI model. The first cell may be the current service cell of the terminal device. The first network device may be at least one of a base station, a CU, a DU, and a LMF, or other network devices. The embodiments of the present application are not limited to this. The function / model identification request message may be carried by media access control (MAC) layer information (e.g., MAC control element (CE), uplink control indicator (UCI) information, radio resource control (RRC) message or other message. The function / model identification request message may be a newly added element in the above-mentioned carrying message or a reused existing element. The embodiments of the present application are not limited to this.

[0069] In some embodiments, after receiving the function / model identification request message, the first network device sends a response message to the terminal device based on the request message.

[0070] As an implementation method, the response message includes a confirmation message indicating that the function / model identification is successful, and the confirmation message includes the local function / model identification information. The local function / model identification information is used to uniquely identify the AI ​​function / model between the terminal device and the first network device, or to uniquely identify the AI ​​function / model on the first network device. In an embodiment of the present application, the local function / model identification information is unique within the first cell (current serving cell), and the local function / model identification information is valid within the first cell. The local function / model identification information may be a local function / model ID, or a local function / model index or other identification information. Optionally, the confirmation information may also include part of the function / model configuration information. For example, the first network device may also send the function / model configuration information that was not reported by the terminal device in step 201 to the terminal device through the response message. Taking the function information to which the model belongs as an example, when the function / model configuration information in step 201 does not include the function information to which the model belongs, the first network device may send the locally valid function information to which the model belongs to the terminal device through the response message for subsequent control of the AI-based function or model.

[0071] In this implementation, the first network device can maintain a correspondence between function / model configuration information and local function / model identification information. After receiving the request message, the function / model configuration information carried by the request message can be compared with the correspondence. When there is local function / model identification information that matches the function / model configuration information in the correspondence, it means that the first network device has allocated local function / model identification information for the function / model, and the first network device sends the matching local function / model identification information to the terminal device; when there is no local function / model identification information that matches the function / model configuration information in the correspondence, it means that the first network device has not yet allocated local function / model identification information for the function / model, and the first network device allocates local function / model identification information for the function / model and sends the newly allocated local function / model identification information to the terminal device. In addition, the first network device can add the newly allocated local function / model identification information and the corresponding model configuration information to the correspondence for maintenance.

[0072] In this implementation, when the response message is a confirmation message, when the terminal device enters a non-connected state, or receives release indication information from a network device, or when the terminal device switches to another cell, the method may further include: (not shown), the terminal device clears the local function / model identification information.

[0073] As an implementation method, the response message includes a rejection message or a failure message for indicating that the function / model identification failed. Optionally, the rejection message or failure message includes a reason for rejection or failure. The reason for rejection or failure may include at least one of the following: missing function / model configuration information, invalid function / model, expired function / model version, function / model not updated to the latest function / model, and not supported by the first network device. For example, when the first network device believes that the function / model configuration information reported by the terminal device is insufficient to uniquely identify the function / model (missing function / model configuration information), the first network device may refuse to allocate local function / model identification information to the terminal device.

[0074] In some embodiments, the response message may be carried by media access control (MAC) layer information (e.g., MAC control element (CE), downlink control indicator (DCI) information, radio resource control (RRC) message, or other messages, but the embodiments of the present application are not limited thereto.

[0075] In some embodiments, before sending the request message, optionally, the method may further include: (not shown) the terminal device is also used to receive the first indication information sent by the first network device to indicate that the first network device supports the function / model recognition function, and / or the second indication information for indicating that the first network device supports the AI ​​function. For example, the standard defines that support for AI functions includes support for function / model recognition functions, and the first network device supporting the AI ​​function may implicitly indicate that the first network device supports the function / model recognition function. The first network device may carry the above two indication information to the terminal device through the same message / step, or may carry the above two information to the terminal device separately through different steps and / or different messages. The embodiments of the present application are not limited to this.

[0076] In some embodiments, the first indication information and / or the second indication information may be carried in at least one of the following messages: a system message, layer 2 signaling, media access control (MAC) layer information (e.g., MAC control element (CE), downlink control indicator (DCI) information), a multicast message, a paging message, a radio resource control (RRC) message, or other messages.

[0077] In some embodiments, when the terminal device receives the first indication information and / or the second indication information, it indicates that the first network device supports local functions / model recognition functions and / or supports AI functions. In this case, the terminal device can send the above-mentioned request message to the first network device.

[0078] The above embodiments are merely exemplary descriptions of the methods of the present application, but the present application is not limited thereto, and appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used individually, or one or more of the above embodiments may be combined.

[0079] This embodiment defines a function / local model identification process, enabling terminal devices and network devices to manage functions / models based on local function / model identification information. In this embodiment, local function / model identification between the terminal device and the network device is only valid within the current serving cell. Maintenance of local function / model identification information by the terminal device is relatively simple.

[0080] Embodiments of the second aspect

[0081] The embodiment of the present application provides a function / model identification method, which is explained from the side of the terminal device. The difference from the embodiment of the first aspect is that, in the embodiment of the first aspect, the local function / model identification information is valid in the current serving cell (first cell) by default. However, with the mobility of the terminal device or other factors (for example, the terminal device enters a non-connected state), the process of local function / model identification may need to be performed multiple times between the terminal device and the network device. Therefore, in the embodiment of the second aspect, in addition to carrying the local function / model identification information in the confirmation message, the network device can also send validity information to the terminal device, thereby avoiding repeated local function / model identification processes and reducing the signaling overhead of frequent local function / model identification processes. The repetitions with the embodiment of the first aspect will not be repeated. Only the differences are described below.

[0082] In some embodiments, the confirmation message further includes function / model validity information, where the function / model validity information includes at least one of the following information: valid area information, valid indication information, and valid time information. The function / model validity information is used to indicate in which areas and / or during which times the local function / model identification information is valid.

[0083] In some embodiments, the valid area information is used to indicate the valid area of ​​the local function / model identification information, including at least one cell global identifier (CGI) information, and / or at least one function / model area identification information. The CGI may include a public land mobile network identifier (PLMN ID) and a cell ID; the function / model area identification information may include a function / model area identifier, or include a PLMN ID and a function / model area identifier, or include a PLMN ID, a tracking area code (TAC) and a function / model area identifier. The valid area at least includes the current cell or the area corresponding to the function / model area identifier to which the current cell belongs, that is, the at least one cell global identification information includes the global identification information of the current cell, or the at least one function / model area identification information includes the function / model area identifier to which the current cell belongs.

[0084] As an implementation method, the function / model area identification information can indicate the valid area with the cell as the basic unit. For example, the function / model area identification information identifies the range of M cells as a valid area, the function / model area identification information of cells 1, 2, and 3 are all 1, and the function / model area identification information of cells 4, 5, and 6 are all 2. The valid area indicated by the function / model area identification information 1 is the cell range of cells 1, 2, and 3, and the valid area indicated by the function / model area identification information 2 is the cell range of cells 4, 5, and 6. Examples are not given one by one here. The valid areas corresponding to different function / model area identification information may not overlap at all (for example, a cell has only one function / model area identification information), or may partially overlap (for example, at least one cell has at least 2 function / model area identification information), and the embodiments of the present application are not limited to this.

[0085] In some embodiments, if the valid area information includes at least one function / model area identification information, the method may further include: the terminal device is further configured to receive the function / model area identification information sent by the first network device. The function / model area identification information may be broadcast or sent via proprietary RRC signaling, and the embodiments of the present application are not limited thereto.

[0086] In some embodiments, the validity indication information is used to indicate that the valid area of ​​the local function / model identification information is not limited to the current cell (the first cell); that is, the valid area includes not only the area of ​​the current cell but also other areas. The validity indication information can be 1 bit of information. When the validity indication information is included in the validity information, the terminal device determines that the valid area of ​​the local function / model identification information is not limited to the current cell.

[0087] In some embodiments, the effective time information is used to indicate the effective time of the local function / model identification information. As an implementation method, the starting time point of the above-mentioned effective time is the time when the terminal device receives the local function / model identification information. Optionally, the terminal device can start a timer, and the maximum running time of the timer is the above-mentioned effective time. When the terminal device receives the local function / model identification information, the terminal device starts the timer. When the running time of the timer reaches the above-mentioned effective time, the terminal device stops the timer, that is, the timer expires. If, while the timer is running (that is, before the timer expires), the terminal device receives an indication message sent by the network device to instruct the terminal device to delete the local function / model identification information, the terminal device may also stop the timer.

[0088] In some embodiments, the method may further include: the terminal device stores the local function / model identification information; optionally, the terminal device may further store the effective area information corresponding to the local function / model identification information, and / or the effective time information; or, store the effective indication information, as well as the identification information of the network device to which the first cell belongs or the CGI of the first cell, and / or the effective time information. The identification information of the network device may be a network device identifier, or a PLMN ID and a network device identifier. Optionally, the terminal device may receive the identification information of the network device sent by the network device, or may confirm the identification information of the network device according to the cell CGI. Or, as an implementation, the terminal device may also receive the rule information and the cell CGI sent by the network device to which the cell belongs, and the rule information is used to instruct the terminal device to confirm the identification information of the network device from the cell CGI. For example, the CGI includes a PLMN ID and a Cell ID, where the length of the cell ID is N, and the rule information may be used for the terminal device to determine that M bits in the cell ID are the identification information of the network device, M < N, and both M and N are positive integers not equal to 0.

[0089] The above embodiments only exemplarily illustrate the methods of the embodiments of the present application, but the present application is not limited thereto, and appropriate variations can be made on the basis of the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0090] Embodiments of the third aspect

[0091] The embodiments of the present application provide a function / model identification method, which is described from the perspective of the terminal device. The difference from the embodiments of the first and second aspects is that the terminal device can also (for example, based on the function / model validity information) judge the validity of the local function / model identification information, especially when the UE moves. Through this validity judgment mechanism, the signaling overhead of the frequent local function / model identification process is reduced. The details are described below, and the repetitions with the embodiments of the first and second aspects will not be elaborated.

[0092] In some embodiments, when the terminal device moves to the second cell, it also determines whether the local function / model identification information is valid in the second cell based on the function / model validity information. The second cell and the first cell may be the same cell or different cells. For example, the terminal device receives the local function / model identification information sent by the first network device to which the first cell belongs, but moves to a second cell different from the first cell, and it is necessary to determine whether the local function / model identification information is valid in the second cell; for example, the terminal device receives the local function / model identification information sent by the first network device to which the first cell belongs, but moves to other cells and then moves back to the first cell (i.e., the second cell), and it is also necessary to determine whether the local function / model identification information is valid in the second cell (i.e., the first cell).

[0093] As an implementation method, the response message is a confirmation message, and the confirmation message includes local function / model identification information and valid area information, and the valid area information includes at least one cell global identification information. The terminal device stores the local function / model identification information and the above-mentioned valid area information. When the terminal device moves to the second cell, the terminal device needs to obtain the cell global identification information of the second cell, and determine whether the local function / model identification information is valid in the second cell based on whether the cell global identification information of the second cell is included in the valid area information. If the cell global identification information of the second cell is included in the valid area information, the terminal device determines that the local function / model identification information is valid in the second cell; and / or, if the cell global identification information of the second cell is not included in the valid area information, the terminal device determines that the local function / model identification information is invalid in the second cell. For example, the valid area information includes cell global identification information of 1, 2, and 3. If the cell global identification information of the second cell is 1, the terminal device determines that the cell global identification information of the second cell is included in the valid area information, thereby determining that the local function / model identification information is valid in the second cell; and / or, if the cell global identification information of the second cell is 4, the terminal device determines that the cell global identification information of the second cell is not included in the valid area information, thereby determining that the local function / model identification information is invalid in the second cell.

[0094] As another implementation method, the response message is a confirmation message, and the confirmation message includes local function / model identification information and valid area information, and the valid area information includes at least one function / model area identification information. The terminal device stores the local function / model identification information and the above-mentioned valid area information. When the terminal device moves to the second cell, the terminal device needs to obtain the function / model area identification information to which the second cell belongs. For example, the terminal device can receive the above-mentioned function / model area identification information sent by the second network device to which the second cell belongs. The terminal device determines whether the local function / model identification information is valid in the second cell based on whether the received function / model area identification information is included in the valid area information. If the received function / model area identification information is included in the valid area information, the terminal device determines that the local function / model identification information is valid in the second cell. And / or, if the received model area identification information is not included in the valid area information, the terminal device determines that the local function / model identification information is invalid in the second cell. For example, the valid area information includes model area identification information of 1, 2, and 3. If the function / model area identification information of the second cell is 1, the terminal device determines that the function / model area identification information of the second cell is included in the valid area information, thereby determining that the local function / model identification information is valid in the second cell; and / or, if the function / model area identification information sent by the second network device to which the second cell belongs is 4, the terminal device determines that the function / model area identification information of the second cell is not included in the valid area information, thereby determining that the local function / model identification information is invalid in the second cell.

[0095] In another implementation, the response message is a confirmation message, and the confirmation message includes local function / model identification information and validity indication information. The terminal device stores the local function / model identification information, the validity indication information, and the identification information of the first network device to which the first cell belongs, or the first cell CGI. When the terminal device moves to a second cell, the terminal device needs to obtain the identification information of the second network device. Based on the validity indication information and whether the identification information of the second network device to which the second cell belongs is consistent with the identification information of the first network device to which the first cell belongs, the terminal device determines whether the local function / model identification information is valid in the second cell. If they are consistent, the terminal device determines that the stored local function / model identification information is valid in the second cell; and / or, if they are inconsistent, the terminal device determines that the stored local function / model identification information is invalid in the second cell. Optionally, the terminal device may receive a second cell CGI sent by the second network device to which the second cell belongs. Further, the terminal device may receive second rule information sent by the second network device. The terminal device may confirm the identification information of the second network device based on the second cell CGI. If the terminal device stores the first cell CGI, the terminal device confirms the identification information of the first network device based on the first cell CGI. The description of how the terminal device confirms the identification information of the network device based on the cell CGI can be referred to the above description and will not be repeated here.

[0096] As another implementation, the response message is a confirmation message, and the confirmation message includes the local function / model identification information and validity period information. The terminal device stores the local function / model identification information and the stored validity period information. The terminal device determines whether the local function / model identification information is valid based on whether the time indicated by the validity period information has expired. If the time after the terminal device receives the local function / model identification information is not longer than, less than, or equal to the validity period information, or if the timer started based on the validity period information is still running or has not expired, the terminal device determines that the stored local function / model identification information is valid, or that the stored local function / model identification information is valid in the first cell. Optionally, the terminal device may continue to determine whether the local function / model identification information is valid in the second cell in conjunction with the aforementioned implementation; for details, please refer to the above description and will not be repeated here. If the time after the terminal device receives the local function / model identification information is longer than, greater than, or equal to the validity period information, or if the timer started based on the validity period information has expired, the terminal device determines that the local function / model identification information is invalid, or that the stored local function / model identification information is invalid in the first cell, or that the stored local function / model identification information is invalid in the second cell.

[0097] The above methods for determining whether local function / model identification information is valid can be implemented separately or in combination, and the embodiments of the present application are not limited thereto.

[0098] In some embodiments, when it is determined that the local function / model identification information is valid, the method may further include (not shown): the terminal device sending the stored local function / model identification information to the second network device to which the second cell belongs. The terminal device does not need to re-initiate the function / model identification process, and the second network device does not need to re-allocate the local function / model identification information.

[0099] In some embodiments, when it is determined that the local function / model identification information is invalid, the terminal device needs to re-initiate the function / model identification process. The method may also include (not shown): the terminal device sends a function / model identification request message to the second network device to which the second cell belongs, requesting the second network device to assign local function / model identification information to the AI ​​function / AI model; and the terminal device is also used to receive a function / model identification response message sent by the second network device; the implementation method of the request message and the response message can refer to the embodiments of the first aspect and / or the second aspect, and will not be repeated here.

[0100] In some embodiments, when the local function / model identification information is determined to be invalid, the terminal device may further clear the local function / model identification information. Optionally, if the terminal device also stores other function / model information, such as function / model validity information, the terminal device may further clear the stored function / model validity information.

[0101] The above three aspects of the embodiments are only illustrative of the methods of the embodiments of the present application, but the present application is not limited thereto. For example, the embodiments of the above aspects can be used alone, or one or more of the embodiments of the above three aspects can be combined.
