[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0050] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: New Radio (NR) system, NR system evolution system, LTE-based access to unlicensed spectrum (LTE-U) system on unlicensed spectrum, NR-based access to unlicensed spectrum (NR-U) system on unlicensed spectrum, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), fifth-generation communication (5G) system, sixth-generation communication (6G) system or other communication systems.

[0051] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement.

Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0063] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0064] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0065] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0066] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0067] (1) Functional configuration process in 5G system

[0068] There are many functions in the 5G communication system. Some functions are mandatory functions for 5G terminals, but most 5G functions are optional functions. The terminal can indicate which optional functions it supports through the capability reporting process. The network equipment configures appropriate configuration information for the terminal device based on the capabilities reported by the terminal and the functions supported by the network device itself.

[0069] Capability information reporting is mostly used to indicate relatively static capability information of terminal devices, and terminal devices can usually understand the meaning of the capabilities themselves. However, for model description information associated with AI (Artificial Intelligence) models, the traditional capability reporting process cannot meet the reporting requirements of model description information.

[0070] (2) Download of OTT (Over the top, third party provides services to users) service model

[0071] Due to the limited capabilities of terminal devices, models on the terminal side are generally trained through third-party platforms (for example, OTT service platforms). Terminal devices can download the required AI model and the model description information associated with the model through the application layer.

[0072] During the functional configuration process of the above-mentioned 5G system, capability information reporting is mostly used to indicate relatively static capability information of terminal devices, and terminal devices can usually understand the meaning of the capability itself. However, for model description information associated with AI models, the traditional capability reporting process cannot meet the reporting requirements of model description information, because much of the configuration information of model training (for example, antenna size) involves product implementation privacy and is generally not allowed to be expressed through the standardization process. However, as part of the model applicability conditions, network devices want to know the model description information associated with the model to facilitate model management (for example, model activation, deactivation, switching, etc.). Therefore, how terminal devices report model description information containing implementation characteristics will be the key issue that needs to be resolved in this case.

[0073] FIG2 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0074] S210. The first terminal device sends first model-related information to the first network device, where the first model-related information includes first information related to an applicable condition of the first model in the first terminal device.

[0075] In an embodiment of the present application, the first terminal device may be any type of terminal device, in which a first model is stored. The first model may be an AI-based model or a machine learning (ML) model, such as a deep learning neural network model. Optionally, the first model may be a model of any function, such as a CSI (Channel State Information) compressed feedback model, a CSI prediction model, a beam prediction model, a positioning model, a mobility control model, a service prediction model, a measurement prediction model, and the like.

[0076] Exemplarily, the first network device may include an access network device and / or a core network device.

[0077] Exemplarily, the access network device is any one of the following: gNB, centralized unit (CU), distributed unit (DU), centralized unit-control plane (CU-CP), centralized unit-user plane (CU-UP).

[0078] Exemplarily, the core network device is any one of the following: location management function (LMF) network element, network slice selection function (NSSF), authentication server function (AUSF), unified data management (UDM), access and mobility management function (AMF), session management function (SMF), policy control function (PCF), user plane function (UPF), sensing control function (SF), network data analysis (NWDAF) network element.

[0079] In an embodiment of the present application, the first model related information is used to describe the first model, which at least includes first information related to the applicable conditions of the first model. Optionally, the first model related information can be carried by any of the following types of messages: NR Positioning Protocol A (NR Positioning Protocol A, NRPPa) message, Long Term Evolution Positioning Protocol (Long Term Evolution Positioning Protocol, LPP) message, Non-Access Stratum (Non-Access Stratum, NAS) message, Radio Resource Control (Radio Resource Control, RRC) message, Media Access Control Element (MAC Control Element, MAC CE) message, Uplink Control Information (Uplink Control Information, UCI) message, Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) message, Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) message, Inter-node message, AI dedicated message.

[0080] Exemplarily, the first model-related message can be carried by a unicast message, a multicast message or a broadcast message. Among them, a unicast message (one-to-one) refers to a message delivered by the first terminal device through a unicast channel. Only the first network device that has allocated the corresponding unicast resources can attempt to receive the unicast message. The unicast message can also be called dedicated signaling. A multicast message (one-to-many) refers to a message delivered by the first terminal device through a multicast channel. Terminal devices or network devices that are within the coverage of the multicast signal and are group members can attempt to receive the multicast message. When a terminal device or network device joins a group, it will obtain multicast channel-related resources. A broadcast message (one-to-any) refers to a message delivered by the first terminal device through a broadcast channel. Any terminal device or network device within the coverage of the broadcast signal can attempt to receive the broadcast message.

[0081] Exemplarily, the first model-related information can be used by the first network device to configure other models related to the first model for the first terminal device, such as configuring a model with the same function as the first model but with different applicable conditions, to facilitate subsequent activation and use. Alternatively, the first model-related information can be used by the first network device to perform operations such as activation, deactivation, function fallback, or switching on the first model. Specifically, the first network device can configure other models for the first terminal device based on the first information related to the applicable conditions of the first model, or perform activation, deactivation, function fallback, or switching operations on the first model.

[0082] It can be seen that according to the above method, the first terminal device reports information related to the applicability conditions of the first model in the first terminal device to the first network device, so that the first network device can obtain relevant information about the applicability conditions of the first model, and thus manage the first model based on the relevant information about the applicability conditions of the first model, such as performing activation, deactivation, function fallback or switching operations on the first model, thereby optimizing the application of the first model and improving system performance.

[0083] In some embodiments, the first information related to the applicable conditions of the first model may include one or more of the following types of information.

[0084] First type of information: device status to which the first model applies.

[0085] In some embodiments, the device state includes information related to the speed of the first terminal device and / or the location of the first terminal device. In other words, the first information related to the applicable conditions of the first model may include information related to the speed adapted to the first model and / or information related to the location adapted to the model. Exemplarily, the information related to the location adapted may include information about the geographic location or geographic area.

[0086] About adaptation speed information:

[0087] The reasoning accuracy of a single model varies greatly for different terminal device speeds (or in other words, a version of the model does not generalize well to the terminal device speed). To meet the model reasoning accuracy requirements of the first terminal device under different speed conditions, the first terminal device can configure multiple versions of models (i.e., multiple models) with the same function on its own, obtain them from a third-party platform, or configure them based on the network. Each version of the model is associated with a type of speed information. In this way, the first terminal device can decide which version of the model to use based on its actual speed information, achieving a relatively high-precision reasoning state.

[0088] For example, the first model is used to predict beam time domain measurement results. The beam time domain measurement result prediction function mainly uses the historical measurement results of one or more beams at one or more past moments to infer the beam measurement results at one or more future moments. Assume that there are four versions of the model that implements the beam time domain measurement result prediction function, namely model 1-1, model 1-2, model 1-3 and model 1-4, and the adaptation speed information associated with each version of the model is low speed, medium-low speed, medium-high speed and high speed. Among them, the meanings of low speed, medium-low speed, medium-high speed and high speed are predefined by system conventions or protocols. For example, low speed refers to 0 to 3 km / h (kilometers per hour), and medium-low speed refers to 3 to 6 km / h. When the first terminal device determines that it is at a low speed, model 1-1 is used, and when the first terminal device determines that it is at a high speed, model 1-4 is used. The first terminal device can report the adaptation speed information of each model to the first network device through the first model related information.

[0089] Based on this, if the first network device determines the surrounding environmental conditions based on historical experience (such as whether it is a downtown area or around a highway), the speed adaptation information reported by the first terminal device can, on the one hand, assist the first network device in deciding whether to activate or deactivate or switch the corresponding model (for example: the first terminal device reports that it has a model version adapted to low speed, and the receiving base station is surrounded by a downtown area, and the terminal speed is generally not too high. After comprehensively judging this information, the first network device can decide to activate the model version adapted to low speed in the first terminal device); on the other hand, the first network device can also know whether the first terminal device lacks some model versions based on this information, thereby configuring the corresponding model version for the first terminal device (for example: the first terminal device reports that it has a model version adapted to low speed, and the receiving first network device is surrounded by highways, and the terminal speed is generally high. After comprehensively judging this information, the first network device can decide to configure an additional model version adapted to high speed for the first terminal device, which is convenient for subsequent activation and use).

[0090] Related information about the adaption position:

[0091] Take the adaptation location-related information including the geographical area information applicable to the model as an example for explanation. For different geographical areas, the reasoning accuracy of a single model varies greatly (or the generalization of a version of the model for geographical locations is not good). In order to meet the model reasoning accuracy requirements of the first terminal device in different geographical area states, multiple versions of models applicable to the same function can be configured for the first terminal device. Each version of the model is associated with a geographical area information that the model is adapted to. In this way, the first terminal device can decide which version of the model to use based on its actual geographical area, thereby achieving a relatively high-precision reasoning state. Among them, the geographical area information includes at least one of longitude information, latitude information, and altitude information.

[0092] For example, the first model is used for positioning reasoning. Assume that there are four versions of the model that implements the positioning reasoning function, namely Model 2-1, Model 2-2, Model 2-3 and Model 2-4, and the adapted geographical areas associated with each version of the model are Geographical Area 1, Geographical Area 2, Geographical Area 3 and Geographical Area 4 respectively (wherein, the meanings of Geographical Area 1, Geographical Area 2, Geographical Area 3 and Geographical Area 4 are predefined by the protocol, for example: Geographical Area 1 corresponds to the children's park area of ​​City A, and Geographical Area 2 corresponds to the residential area of ​​City A), then when the first terminal device determines that its own location is in Geographical Area 1, Model 2-1 is used, and when the first terminal device determines that its own location is in Geographical Area 4, Model 2-4 is used. The first terminal device can report the geographical area information adapted by each model to the first network device through the first model related information.

[0093] Based on this, on the one hand, the first network device can decide whether to activate or deactivate or switch the corresponding model on the first terminal device side based on the geographical area information of the model adaptation reported by the first terminal device and the geographical area information of the first network device itself; on the other hand, based on the geographical area information of the model adaptation reported by the first terminal device, if the first network device finds that the first terminal device lacks a model version applicable to this area, it can also additionally configure a model version applicable to this area for the first terminal device, to facilitate subsequent activation and use, and to achieve system performance improvement.

[0094] The second type of information: device information of the terminal device to which the first model is applicable.

[0095] In some embodiments, the device information of the terminal device to which the first model is applicable includes hardware information and / or software information of the terminal device.

[0096] The operational performance of a terminal device model is significantly affected by the device's hardware and / or software implementation. For example, with regard to hardware, the same model may run on a device with large memory but not on a device with small memory, or on a device with an 8-core CPU but not on a device with a 4-core CPU. Another example, with regard to software, the same model may run on a device with a first operating system but not on a device with a second operating system. Similarly, factors influencing model operation include the size and distribution of the device's antennas. Specifically, there are many other hardware and / or software factors that actually affect the operational performance of terminal device models, and since these factors vary depending on the product implementation of each manufacturer, it is impossible to list them all here.

[0097] According to an embodiment of the present application, the first terminal device can report the hardware information and / or software information applicable to the first model through the first model related information. It should be understood that the hardware information here refers to information used to characterize specific hardware, for example, it can be the identification information of the specific hardware (such as type, configuration, model, ID, size, etc.), or a string or information container associated with the specific hardware. Similarly, software information refers to information used to characterize a specific software configuration (such as an operating system, algorithm type, etc.), for example, it can be the identification information of the specific software configuration (type, ID, version number, etc.), or a string or information container associated with the specific software configuration.

[0098] Based on this, the first network device can perform management operations related to the first model based on the device information reported by the first terminal device, such as downloading other models that match the above-mentioned hardware information and / or software information, assisting the first model activation / deactivation / switching decision, etc., thereby improving system performance. It should be emphasized that although the first network device may not be able to specifically understand the actual meaning represented by the second type of information (that is, it is unable to understand the hardware and / or software implementation configuration of the first terminal device), the first network device can still use the reported second type of information to perform information matching operations, such as: activating the first model when the second type of information matches successfully, and deactivating or not activating the first model when the second type of information matches unsuccessfully.

[0099] The third type of information: applicable condition information related to the implementation of the first model.

[0100] In some embodiments, the implementation method of the first model may include a training method for the first model. The applicable condition information related to the implementation method of the first model can be used to characterize detailed information of the training method, such as the platform type used for training the first model, the algorithm type, the training configuration information, the terminal device type considered during training, etc. Optionally, the applicable condition information can be the detailed information of the training method itself, or other information used to characterize the detailed information of the training method, such as a string or information container associated with the detailed information.

[0101] According to an embodiment of the present application, the first terminal device can report applicable condition information related to the implementation of the first model through the first model related information. Based on this, the first network device can implement management operations related to the first model based on the applicable condition information related to the implementation of the first model, such as model download requirement matching, auxiliary model activation / deactivation / switching decision, and other operations, thereby improving system performance.

[0102] The fourth type of information: configuration information applicable to the first model.

[0103] In some embodiments, the configuration information includes one or more of measurement configuration information, logical area configuration information, and frequency domain resource configuration information. It should be noted that the first model is applicable to a certain configuration information, which means that the first model can only work with high precision in the configuration environment associated with the configuration information.

[0104] About measurement configuration information:

[0105] Exemplarily, the measurement configuration information includes one or more of the following information:

[0106] SSB (Synchronization Signal / PBCH Block) resource configuration information, CSI-RS (CSI-Reference Signal) resource configuration information, SRS (Sounding Reference Signal) resource configuration information, and PRS (Positioning Reference Signal) resource configuration information.

[0107] Optionally, the resource configuration information in the measurement configuration information may include configuration information of one or more of time domain resources, frequency domain resources, and spatial domain resources.

[0108] For example, the first model related information reported by the first terminal device includes CSI-RS resource configuration information applicable to the first model, but at this time the first network device has configured another set of CSI-RS resource configuration for the first terminal device, so the first model associated with the first model related information should not be activated and used.

[0109] About logical area configuration information:

[0110] Illustratively, the logical area configuration information includes one or more of the following information:

[0111] PLMN (Public Land Mobile Network) identification information, CAG (Closed Access Group) identification information, SNPN (Stand-alone Non-public Networks) identification information, TAC (Tracking Area Code) identification information, RANAC (RAN Area Code) identification information, model effective area dedicated identification information, cell identification information. Optionally, the cell identification information is represented by a CGI (Cell Global Identity) or a cell index. Alternatively, the cell identification information is represented by a PCI (Physical Cell Identity) and a frequency combination.

[0112] For example, the first model related information reported by the first terminal device includes cell identification information of frequency 1 and PCI 1, but the first network device is the cell corresponding to frequency 2 and PCI 2. At this time, the first model associated with frequency 1 and PCI 1 should not be activated and used.

[0113] About frequency domain resource configuration information:

[0114] Exemplarily, the frequency domain resource configuration information includes one or more of the following information:

[0115] Frequency point identification information, frequency band identification information, and frequency band combination identification information.

[0116] For example, the first model related information reported by the terminal device includes frequency band 1 identification information, but the frequency band used by the first network device is frequency band 2 (for example, indicated by frequency band 2 identification information). At this time, the model associated with the first model related information should not be activated and used.

[0117] By reporting the above-mentioned fourth type of information, on the one hand, the first network device can decide whether to activate or deactivate or switch the corresponding model on the first terminal device side based on the configuration information of the model adaptation reported by the first terminal device and the configuration information of the first network device itself; on the other hand, based on the configuration information of the model adaptation reported by the first terminal device, if the first network device finds that the first terminal device lacks model versions applicable to certain configurations, it can also additionally configure model versions applicable to these configurations for the first terminal device, so as to facilitate subsequent activation and use, thereby improving system performance.

[0118] The fifth type of information: device information of the network device to which the first model applies.

[0119] In some embodiments, the device information of the network device to which the first model is applicable includes hardware information and / or software information of the network device.

[0120] Exemplarily, hardware information refers to information used to characterize specific hardware, such as identification information of the specific hardware (e.g., type, configuration, model, ID, size, etc.), or a string or information container associated with the specific hardware. Similarly, software information refers to information used to characterize a specific software configuration (e.g., operating system, algorithm type, etc.), such as identification information of the specific software configuration (e.g., type, ID, version number, etc.), or a string or information container associated with the specific software configuration.

[0121] Generally speaking, the information covered by the hardware and / or software of network equipment is relatively broad, such as: the size, shape or distribution of the antenna deployed on the network equipment, the beamforming algorithm, the mapping relationship between the beam direction and the antenna port, the number or distribution of antenna ports, the layer 1 filtering algorithm, the geographical distribution of TRP (transmission and reception point), etc. These hardware / software configurations are closely related to the operating performance of the model. The same model can achieve good model inference accuracy under the management of an adapted network device. Conversely, the inference performance of the same model will be severely reduced under the management of an inappropriate network device. By reporting the fifth type of information mentioned above, the first network device can determine whether the first model currently deployed by the first terminal device is suitable for activation and use, so as to implement model-related management operations, such as model download demand matching, auxiliary model activation / deactivation / switching, and other operations, thereby improving system performance.

[0122] The sixth type of information: network deployment information applicable to the first model.

[0123] The network deployment information may also be understood as scenario information applicable to the first model. Exemplarily, the scenario information is used to indicate a base station deployment scenario.

[0124] Exemplarily, the network deployment information may be used to indicate one or more of the following scenarios:

[0125] InH (Indoor hotspot);

[0126] InF (Indoor factory);

[0127] UMa (Urban Macro, urban macro station);

[0128] UMi (Urban Micro, urban micro station);

[0129] RMa (Rural Macro, rural macro station).

[0130] Some models have poor generalization and can only be associated with one base station deployment scenario, such as Model A associated with the InF scenario. Other models have better generalization and can be associated with multiple base station deployment scenarios, such as Model B associated with both UMa and UMi scenarios. By reporting the sixth type of information, the first network device can determine whether the first model is suitable for the current network deployment scenario. This allows for model-related management operations, such as matching model download requirements and assisting in model activation / deactivation / switching decisions, thereby improving system performance.

[0131] Optionally, in another implementation, the fifth and sixth categories of information may be combined into one type of information and reported.

[0132] The seventh type of information: information on input data requirements for the application of the first model.

[0133] Model training requires a data set. Different models trained with data sets with different characteristics are obviously applicable to different data sets (or the model can only work with high precision in the corresponding training data set environment). Therefore, reporting the seventh type of information can allow the first network device to clearly know the data set conditions applicable to the first model, so that the first network device can adapt the model-related configuration and activate the first model for use, or not activate, deactivate or switch the model if the data set conditions do not match its own configuration.

[0134] Optionally, in another implementation, the third type of information and the seventh type of information may be combined into one type of information and reported.

[0135] It should be noted that the first information related to the applicable conditions of the first model may include any one or more of the above-mentioned information from the first to the seventh categories. For example, the first information may include measurement configuration information applicable to the first model and scenario information applicable to the first model. The first network device can then determine whether the first model is suitable for activation and use based on the current measurement configuration and the deployment scenario of the first network device. In actual applications, the content of the first information can be set according to scenario requirements, system conventions, or protocol definitions, and they are not listed here one by one.

[0136] In some embodiments, one or more pieces of information in the first information are character strings. Specifically, the one or more pieces of information in the first information are character strings associated with the information, which can be used for information matching or filtering, or can be used by a specific device to assist the first network device in model management and control after parsing the information.

[0137] Exemplarily, one or more of the second, third, fifth, sixth, and seventh categories of information in the first information is a string. For example, device information of a terminal device applicable to the first model is a first string, applicable condition information related to the implementation of the first model is a second string, device information of a network device applicable to the first model is a third string, network deployment information applicable to the first model is a fourth string, and input data requirement information applicable to the first model is a fifth string. In another implementation, the one or more categories of information described above may also be represented by a single string, with different parts of the string representing different categories of information.

[0138] Taking the second type of information contained in the first information (device information of the terminal device to which the first model applies) as an example, network devices generally do not need to understand the device information of the terminal device to which the first model applies. The hardware and / or software implementation characteristics on the terminal device side cannot be expressed in the form of a specific parameter list. On the one hand, this involves commercial secrets and is not something that can be expressed specifically; on the other hand, there are too many hardware and / or software factors, making it difficult to explain and express them specifically. However, these implementation characteristic information are crucial for the use and sharing of terminal-side models. If a terminal device needs to download a terminal-side model uploaded and shared by another terminal device from a network device, the terminal device needs to provide information that can characterize its hardware and / or software implementation characteristics. In this way, the network device will find a terminal-side model that matches it based on this hardware and / or software implementation characteristic information and configure it for the terminal device.

[0139] For example: Manufacturer A expresses the hardware and / or software implementation characteristics of the X3 mobile phone with the string 'aa', expresses the hardware and / or software implementation characteristics of the X4 mobile phone with the string 'ab', and expresses the hardware and / or software implementation characteristics of the X5 mobile phone with the string 'ac'; while Manufacturer B expresses the hardware and / or software implementation characteristics of the i8 mobile phone with the string 'kkq', expresses the hardware and / or software implementation characteristics of the i9 mobile phone with the string 'kkw', and expresses the hardware and / or software implementation characteristics of the i10 mobile phone with the string 'kke'.

[0140] In exemplary scenario 1, the second terminal device in the communication system is an X5 mobile terminal, which reports the string 'ac' when requesting to download a model from the first network device. If the first terminal device (such as another X5 mobile terminal) has reported the string 'ac' when reporting information related to the first model, the first network device can configure the first model associated with the string 'ac' to the second terminal device.

[0141] In exemplary scenario 2, the first terminal device is an X5 mobile terminal. The X5 mobile terminal already has a corresponding terminal-side model. The string 'ac' and the associated model are uploaded to the network device to implement a model sharing mechanism between terminal devices through the network device. The string 'ac' information can be used as one of the bases for model matching and screening by the network device.

[0142] In exemplary scenario 3, the first terminal device is an X5 mobile terminal, which already has a corresponding terminal-side model. The string 'ac' information associated with the model is reported to the first network device. Although the first network device cannot understand the actual meaning of the string, based on historical practical experience, it knows that the second terminal device corresponding to the string 'ac' can run the model in the current configuration environment, so the corresponding model is activated for the second terminal device.

[0143] It can be seen that when the second type of information is a character string, the hardware and / or software implementation characteristics of the first terminal device can be hidden from the first network device to protect user privacy, and the first network device can use the character string associated with the hardware and / or software implementation characteristics of the first terminal device to implement model-related management operations.

[0144] Taking the third type of information contained in the first information (applicable condition information related to the implementation method of the first model) as an example, if the first model is trained by a third-party platform (terminal device or cloud service provider), the first network device generally does not need to understand the specific meaning expressed by the third type of information; if the first model is trained by a third-party platform (network device or cloud service provider), the first terminal device generally does not need to understand the specific meaning expressed by the third type of information.

[0145] Many AI models used by terminal devices are not always trained by the terminal devices themselves. Many terminal-side models are downloaded from cloud service providers or network devices. If the terminal-side model is trained by a third-party manufacturer such as a cloud service provider or network vendor, for the sake of commercial confidentiality, the third-party manufacturer does not want the terminal device to know the details of the model training, such as the platform type used for model training, the algorithm type used for model training (such as neural network or fully connected network), the terminal device configuration information used for model training, and the terminal device types considered for model training. Although this model implementation information cannot be expressed in parameters (for commercial privacy reasons), it is crucial for the normal use of the model. The third type of information can serve as one of the important bases for model request or screening. In one usage scenario, when a third party provides a model to a first terminal device, it will provide the third type of information (a string) to the first terminal device. After the first terminal device connects to a cell, it can report the third type of information to the first network device in the serving cell. The first network device can perform a matching operation based on the third type of information. For example, if the vendor of the serving cell happens to be the network vendor that trained the first model associated with the third type of information, the first network device can consider activating the first model. In another usage scenario, the first model is trained by the cloud service provider and provided to the terminal device, and the third type of information associated with the first model is also provided. Since the cloud service provider has signed a cooperation agreement with several network manufacturers or operators (the network manufacturers or operators will maintain a valid third-party third-type information list), when the first terminal device reports the third type of information to the first network device, the first network device can determine whether the first model associated with the third type of information is a model that can be used as agreed in the cooperation agreement based on the third type of information reported by the first terminal device and the locally maintained third type of information list, thereby determining whether the first model is suitable for use in this network.

[0146] For example, the cloud service provider trains a time-domain prediction model for beam measurement results for the first terminal device and assigns a model implementation string "www" (i.e., the third type of information) to the model. The first terminal device can report the string "www" to the first network device. In one scenario, it can request the first network device to download other models associated with the string "www"; in another scenario, the first network device can query the local database based on the string "www" and determine whether the model associated with the information can be used. If so, it sends a model activation command to the first terminal device.

[0147] It can be seen that when the third type of information is a character string, the details of the model training can be hidden from the first terminal device and / or the first network device to protect the privacy of the model developer, and the first network device can also use the character string associated with the implementation method of the first model to implement model-related management operations.

[0148] Taking the fifth category of information contained in the first information (device information of the network device to which the first model applies) as an example, the first terminal device generally cannot understand the actual meaning of the fifth category of information because it involves a lot of commercial information from network vendors. Although the first terminal device cannot understand the actual meaning of the fifth category of information, as part of the model's applicability conditions, the model provider (cloud service provider or network vendor or operator) can also provide the string information corresponding to the fifth category of information together with the model itself to the first terminal device when providing the AI ​​model to the first terminal device. After entering a cell, the first terminal device can report the string information associated with the model to the first network device in the cell, allowing the first network device to determine whether the model currently deployed on the terminal device is suitable for activation and use based on this information.

[0149] It can be seen that when the fifth category of information is a character string, the network manufacturer's information can be hidden from the first terminal device to protect the privacy of the network manufacturer. The first network device can also use the character string associated with the device information of the network device used by the first model to implement model-related management operations. The first network device can understand the actual meaning of the character string information corresponding to the fifth category of information (for example: the network device is the corresponding model provider) or the first network device cannot understand the actual meaning of the character string information corresponding to the fifth category of information (for example: the network device is the cooperative user of the corresponding model provider).

[0150] Taking the sixth category of information contained in the first information (network deployment information applicable to the first model) as an example, the first terminal device generally cannot understand the actual meaning of the sixth category of information. However, by using a character string associated with the network deployment scenario applicable to the first model as the sixth category of information for reporting, the first network device can use the character string to implement management operations related to the model.

[0151] In some embodiments, the fifth and sixth categories of information can be combined into one category for reporting, as neither of these categories of information requires comprehension by the terminal device. Combined reporting can simplify the design of the reporting information. In other embodiments, the fifth and sixth categories of information can be reported separately, providing greater flexibility for network device implementation without the need to combine the two categories of information for implementation.

[0152] In some embodiments, one or more types of information in the first information are carried by an information container. The information carried by the information container can only be parsed by a specific device, and one or more nodes on its transmission link may not be able to parse the information in the information container. In other words, the first terminal device or the first network device does not need to understand the actual meaning of the information carried by the information container, and can be implemented in a manner similar to the above-mentioned string application method, and achieves a similar effect as the above-mentioned string application method, which will not be repeated here.

[0153] It should be noted that if a string is reported, although the first network device cannot understand the specific meaning, it can still parse the reported string information. For example, after X5 reports the second type of information, the network device parses and obtains the string 'ac'. If container information is reported, the network device cannot understand the specific meaning and cannot obtain the string information. All it gets is a computer bit sequence, such as "010010101". However, whether it is a string or an information container, the network device can save the received information and use this information to perform logical screening or matching.

[0154] Exemplarily, one or more of the second, third, fifth, sixth, and seventh categories of information in the first information is carried by an information container. For example, device information of a terminal device to which the first model is applicable is carried by a first information container, applicable condition information related to the implementation of the first model is carried by a second information container, device information of a network device to which the first model is applicable is carried by a third information container, network deployment information applicable to the first model is carried by a fourth information container, and input data requirement information applicable to the first model is carried by a fifth information container. In another implementation, the above-mentioned one or more categories of information can also be carried by one information container, with different parts of one information container representing different categories of information.

[0155] It is understandable that, whether it is a string or an information container, the specific meaning of such information does not need to be discussed in detail at the standard level. For example, the standard level does not need to specifically define how many parameters each string identification information or container information includes. The implementation method of string identification information or container information not only simplifies the workload of standardization discussions, but also leaves flexibility for development implementation, and the engineering implementation has good scalability.

[0156] In some embodiments, the first model-related information further includes second information, where the second information includes one or more of the following:

[0157] The ID (Identifier) ​​of the first model;

[0158] Type information of the input parameters of the first model;

[0159] Type information of the output parameters of the first model;

[0160] Functional information of the first model.

[0161] In one implementation, the ID information of the first model includes a parameter. In this case, the ID information of the first model is used to identify a class of models (this class of models performs the same function) or to identify a specific model. For example, there may be multiple physical models for performing beam time domain measurement result prediction, some of which are suitable for high-speed terminal states, some for low-speed terminal states, some for high-frequency scenarios, and some for low-frequency scenarios. Although the specific model applicability conditions are different, these models are all used to perform the beam time domain measurement result prediction function. These physical models that perform the same function are called a class of models. If the ID information of the first model can clearly point to a physical model under a specific condition under a function, the ID information of the first model is used to identify a specific model. The former method (the ID information of the first model is used to identify a type of model) allows the network device to not know whether the terminal device specifically maintains several physical models under the same function. The network device management is simple because it only needs to consider which function to activate the model. The terminal device can choose or switch which physical model needs to be activated under this function according to the actual situation. The latter method (the ID information of the first model is used to identify a specific model) allows the network device to have greater control over model management. The network device can comprehensively judge which specific model under this function should be activated or switched to in the current situation, avoiding the situation where the specific model activated after the terminal device's autonomous judgment does not match the network device configuration. Of course, in this way, the terminal device is relatively simple to implement, because the terminal device only needs to activate which specific model under this function according to the instructions of the network device, and the terminal device does not need to make autonomous judgments and decisions.

[0162] In another implementation, the ID information of the first model includes two parameters (represented by parameter 1 and parameter 2), where parameter 1 is used to identify the model type, that is, to identify a class of models (models of this class perform the same function), and parameter 2 is used to point to a specific model. For example, parameter 1 takes the value 'A' and is used to indicate a model that performs beam time domain measurement result prediction (a class of models), while parameter 2 takes the values ​​'00', '01', '10', and '11', where '00' indicates a model operating at low frequency and low speed, '01' indicates a model operating at low frequency and high speed, '10' indicates a model operating at high frequency and low speed, and '11' indicates a model operating at high frequency and high speed. Parameters 1 and 2 can be used in combination to uniquely identify a specific model, while parameter 1 alone can only indicate a class of models with the same function. This implementation method is more flexible, and you can choose to report parameter 1 or both parameters 1 and 2 according to different needs.

[0163] Optionally, regardless of which of the above implementation methods is used, all or part of the information contained in the first model ID information is obtained through a predefined method, a network configuration method, or a custom method. If the first model ID information contains multiple sub-information, the acquisition methods of the multiple sub-information may be the same or different.

[0164] Exemplarily, if the ID of the first model itself has a definite association relationship with the type information of the input parameters and the type information of the output parameters, that is, the type information of the model input parameters and the type information of the model output parameters can be obtained through the ID of the first model (for example, confirmed by the default mapping relationship), then the second information may include the ID of the first model, or include the ID of the first model and the functional information. That is, the second information may not include the type information of the model input parameters and the type information of the model output parameters. Similarly, if the ID of the first model itself has a definite association relationship with the functional information of the first model, then the second information may include the ID of the first model, or include the ID of the first model, the type information of the input parameters and the type information of the output parameters, but not the functional information of the first model. If the ID of the first model can confirm the type information of the input parameters of the first model, the type information of the output parameters of the first model and the functional information of the first model through the default association relationship, then the second information only needs to include the ID of the first model.

[0165] Exemplarily, the functional information of the first model represents the specific function of the first model application, for example: for the CSI function, the applicable functional information can be used to distinguish different functional branches of the CSI function, for example: distinguishing the CSI compression feedback function and the CSI time domain prediction function; for the beam function, the applicable functional information can be used to distinguish different functional branches of the beam function, for example: distinguishing the beam measurement result spatial domain prediction function and the beam measurement result time domain prediction function; for the positioning function, the applicable functional information can be used to distinguish different functional branches of the positioning function, for example: distinguishing the terminal device directly participating in the positioning function and the terminal device indirectly participating in the positioning function.

[0166] By setting the above second information in the first model related information, the first network device can obtain comprehensive model description information or manage and maintain the corresponding first model related information based on the model identification, thereby facilitating management operations on the first model and improving system performance.

[0167] In some embodiments, the above information transmission method may further include:

[0168] The first terminal device receives third information sent by the first network device; wherein the third information includes:

[0169] IDs of one or more models corresponding to the first model related information requested by the first network device; and / or,

[0170] The first indication information is used to request the first terminal device to send first model related information.

[0171] Exemplarily, the third information includes the first indication information, but does not include the IDs of the one or more models. The first terminal device may report the first model-related information based on the model stored in itself or the updated model.

[0172] Exemplarily, the third information includes the first indication information and the IDs of one or more models corresponding to the first model-related information requested by the first network device. The one or more models corresponding to the first model-related information requested by the first network device are, that is, the one or more models that the first network device is concerned about. The third information includes the IDs of the one or more models, thereby constraining the scope of the models involved in the first model-related information reported by the first terminal device. Exemplarily, the IDs of the one or more models corresponding to the first model-related information reported by the first terminal device are a subset of the IDs of the one or more models contained in the third information.

[0173] Exemplarily, the third information includes the IDs of the one or more models, but does not include the first indication information. The one or more model identification information that the first network device is interested in implies a request for the first terminal device to send information related to the first model.

[0174] Optionally, the step of receiving the third information may be performed before the first terminal device sends the first model related information to the first network device.

[0175] In some embodiments, the information transmission method further includes the first terminal device sending fourth information to the first network device; wherein the fourth information includes one or more of the following:

[0176] IDs of one or more models stored in the first terminal device;

[0177] IDs of one or more models updated by the first terminal device;

[0178] The second indication information is used to indicate that the first terminal device contains the first model related information to be reported or to indicate that the first model related information has been updated.

[0179] Exemplarily, the fourth information may include the second indication information to trigger the first network device to send the third information, thereby reporting the first model related information based on the third information.

[0180] Exemplarily, the fourth information may include the second indication information, and also include the IDs of one or more models stored by the first terminal device or the IDs of one or more models updated by the first terminal device, so that the first network device can determine the ID of the model that the network device is concerned about from the IDs of one or more models stored or updated by the first terminal device.

[0181] Exemplarily, the fourth information may include the IDs of one or more models stored in the first terminal device or the IDs of one or more models updated by the first terminal device, but does not include the second indication information. The model ID implicitly indicates that the first terminal device contains information related to the first model to be reported or is used to indicate that the information related to the first model has been updated.

[0182] Optionally, the step of sending the fourth information may be performed before the first terminal device sends the first model related information to the first network device. Optionally, in an embodiment including the transmission of the third information, the step of sending the fourth information may also be performed before the first terminal device receives the third information.

[0183] In some embodiments, the information transmission method may include a first configuration process for the first model related information. Exemplarily, the first configuration process may include at least one of the following:

[0184] The first terminal device sends fourth information to the first network device;

[0185] The first terminal device receives third information sent by the first network device.

[0186] Optionally, the first configuration process is a dynamic configuration process (or called a timely instruction process). Exemplarily, the dynamic configuration process may be a configuration process that is executed for each transmission of the first model related information.

[0187] In some embodiments, the above information transmission method may further include:

[0188] The first terminal device receives the third indication information sent by the first network device and / or the ID information of one or more models that the first network device is concerned about (i.e., the IDs of one or more models corresponding to the first model related information requested by the first network device), wherein the third indication information is used to indicate whether the first terminal device is allowed to send the first model related information, and the ID information of the one or more models that the first network device is concerned about is used to indicate the model ID range corresponding to the first model related information expected to be sent.

[0189] By setting the third indication information, the first terminal device triggers the sending of the first model related information when permitted, so that the first network device can control the transmission of the first model related information, which is conducive to controlling the transmission resource overhead.

[0190] In some embodiments, the above information transmission method may further include the first terminal device sending capability reporting information to the first network device; wherein the capability reporting information includes:

[0191] Whether the first terminal device supports sending first model related information; and / or,

[0192] The first terminal device supports sending one or more model IDs corresponding to the first model-related information.

[0193] Through the capability reporting process, the first network device can control the transmission of the first model related information according to the capability of the first terminal device.

[0194] In some embodiments, the information transmission method may include a second configuration process for the first model related information. Exemplarily, the second configuration process may include at least one of the following:

[0195] The first terminal device sends capability reporting information to the first network device;

[0196] The first terminal device receives the third indication information sent by the first network device and / or ID information of one or more models that the first network device is interested in.

[0197] Optionally, the second configuration process is a semi-static configuration process (the configuration included in the semi-static configuration process can be updated through a reconfiguration process). Exemplarily, the semi-static configuration process can be a configuration process pre-executed for multiple transmissions of the first model related information.

[0198] In some embodiments, the information transmission method may include the above-mentioned first configuration process and the second configuration process. Optionally, the first configuration process and the second configuration process may perform different transmission controls. For example, the first network device may send the IDs of one or more models that the first network device is concerned about to the first terminal device during the second configuration process; thereafter, for a certain model-related information reporting, the first network device may send a third message during the first configuration process, which carries the first indication information, to trigger the first terminal device to perform the reporting of the first model-related information. For another example, the first network device may send a third indication message to the first terminal device during the second configuration process to indicate that the first terminal device is allowed to send the first model-related information; thereafter, for a certain model-related information reporting, the first network device may send a third message during the first configuration process, which carries the IDs of one or more models that the first network device is concerned about, to control the model ID range involved in the model-related information reporting process.

[0199] To facilitate understanding of the above technical solution, FIG3 shows a schematic diagram of an information transmission method in an application example. Among them, steps S310-S340 are optional and not required steps. As shown in FIG3, the information transmission method may include the following steps:

[0200] S310. The first terminal device sends capability reporting information to the first network device;

[0201] S320. The first terminal device receives third indication information sent by the first network device and / or ID information of one or more models that the first network device is interested in; the third indication information is used to indicate whether the first terminal device is allowed to send information related to the first model;

[0202] S330. The first terminal device sends fourth information to the first network device; wherein the fourth information includes one or more of the following: IDs of one or more models stored by the first terminal device; IDs of one or more models updated by the first terminal device; and second indication information, where the second indication information is used to indicate that the first terminal device contains information related to the first model to be reported or to indicate that the information related to the first model has been updated.

[0203] S340. The first terminal device receives the third information sent by the first network device; wherein the third information includes: the ID of one or more models corresponding to the first model related information requested by the first network device; and / or, the first indication information, the first indication information is used to request the first terminal device to send the first model related information.

[0204] S350. The first terminal device sends first model related information to the first network device.

[0205] Among them, step S310 to step S340 are optional but not necessary steps. In actual application, they can be set according to different scenario requirements or system conventions.

[0206] According to the above-mentioned embodiments of the present application, the definition of the first model-related information (i.e., model applicability condition information) avoids the disclosure of privatization project implementation information. The performance of the model is affected by many factors. Some information can be disclosed to the terminal device (such as reference signal configuration), and some cannot be disclosed to the terminal device (for example, the size or shape of the antenna deployed by the network device, the beamforming algorithm, the mapping relationship between the beam and the antenna port, etc.). By defining the first model-related information in a fuzzy manner to a certain extent (leaving a certain space for implementation), the implementation-related information can be avoided from being disclosed to the terminal device or the network device, thereby protecting the privacy of the terminal device side, the model developer or the network device side engineering implementation to a certain extent.

[0207] As described above, the first network device may include a core network device or an access network device. Accordingly, an embodiment of the present application also provides an information transmission method performed by the core network device or the access network device. Figure 4 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes:

[0208] S410. The first core network device receives first model-related information sent by the first terminal device; wherein the first model-related information includes first information related to the applicable conditions of the first model in the first terminal device.

[0209] In some embodiments, the first information includes one or more of the following:

[0210] The state of the device to which the first model applies;

[0211] Device information of the terminal device to which the first model is applicable;

[0212] Applicable condition information related to the implementation of the first model;

[0213] Configuration information applicable to the first model;

[0214] Device information of the network device to which the first model applies;

[0215] Network deployment information applicable to the first model;

[0216] The first model applies to the input data required information.

[0217] The content and application of the first information can refer to the corresponding description of the above embodiment and will not be repeated here.

[0218] In some embodiments, one or more of the first information is a string. For example, device information of a terminal device to which the first model applies is a first string, and / or applicable condition information related to the implementation of the first model is a second string, and / or device information of a network device to which the first model applies is a third string, and / or network deployment information to which the first model applies is a fourth string, and / or input data requirement information to which the first model applies is a fifth string.

[0219] In some embodiments, one or more of the first information is carried by an information container. For example, device information of a terminal device to which the first model applies is carried by a first information container, and / or applicable condition information related to the implementation of the first model is carried by a second information container, and / or device information of a network device to which the first model applies is carried by a third information container, and / or network deployment information to which the first model applies is carried by a fourth information container, and / or input data requirement information to which the first model applies is carried by a fifth information container.

[0220] In some embodiments, the first model-related information further includes second information, where the second information includes one or more of the following:

[0221] The identification ID of the first model;

[0222] Type information of the input parameters of the first model;

[0223] Type information of the output parameters of the first model;

[0224] Functional information of the first model.

[0225] In some embodiments, the information transmission method further includes the first core network device sending third information to the first terminal device; wherein the third information includes:

[0226] IDs of one or more models corresponding to the first model related information requested to be obtained by the first core network device; and / or,

[0227] The first indication information is used to request the first terminal device to send first model related information.

[0228] In some embodiments, the information transmission method further includes, the first core network device receiving fourth information sent by the first terminal device; wherein the fourth information includes one or more of the following:

[0229] IDs of one or more models stored in the first terminal device;

[0230] IDs of one or more models updated by the first terminal device;

[0231] The second indication information is used to indicate that the first terminal device contains the first model related information to be reported or to indicate that the first model related information has been updated.

[0232] In some embodiments, the information transmission method also includes the first core network device sending third indication information and / or ID information of one or more models that the first core network device is concerned about to the first terminal device, and the third indication information is used to indicate whether the first terminal device is allowed to send first model related information.

[0233] In some embodiments, the information transmission method further includes, the first core network device receiving capability reporting information sent by the first terminal device; wherein the capability reporting information includes:

[0234] Whether the first terminal device supports sending first model related information; and / or,

[0235] The first terminal device supports sending one or more model IDs corresponding to the first model-related information.

[0236] Among them, the capability reporting information, the third indication information, the fourth information and the third information can be implemented according to the corresponding description of the aforementioned embodiment, and will not be repeated here.

[0237] Optionally, the entire set or a subset of the first model information may be transmitted between a core network device and an access network device, or between core network devices.

[0238] Specifically, in some embodiments, the information transmission method further includes:

[0239] The first core network device sends second model related information to the first access network device; wherein the second model related information includes a subset of the first model related information.

[0240] Specifically, the second model-related information may include the first model-related information, or include a subset consisting of partial information of the first model-related information. That is, the second model-related information may include all or part of the first model-related information. For example, if the first model-related information includes configuration information, ID, and functional information applicable to the first model, then the second model-related information may include the configuration information, ID, and functional information applicable to the first model, or include the configuration information and ID applicable to the first model, or include the first model-related information corresponding to a partial ID.

[0241] According to this embodiment, information related to the first model is stored in the first core network device and transmitted by the first core network device to the first access network device, enabling the first access network device to perform management operations, such as model activation, deactivation, or switching. This eliminates the need for the first terminal device to report information related to the first model to the first access network device each time it enters a connected state, thus reducing information reporting overhead.

[0242] In some embodiments, the information transmission method may further include:

[0243] The first core network device sends third model related information to the second core network device; wherein the third model related information includes a subset of the first model related information.

[0244] Specifically, the third model-related information may include the first model-related information, or include a subset consisting of partial information of the first model-related information. That is, the third model-related information may include all or part of the first model-related information.

[0245] Optionally, the third model-related information may be the same as or different from the second model-related information. For example, if the first model-related information includes configuration information, ID, and functional information applicable to the first model, and the second model-related information transmitted by the first core network device to the first access network device includes the configuration information and ID applicable to the first model, then the third model-related information transmitted by the first core network device to the second core network device may include the configuration information, ID, and functional information applicable to the first model, or include the configuration information and ID applicable to the first model.

[0246] According to the above embodiment, when the service core network device of the first terminal device changes (for example, the core network device is replaced due to the mobility of the first terminal device), the continuity of the maintenance of model-related information can be maintained through information interaction between the source core network device and the target core network device, thereby avoiding the first terminal device from reporting model-related information again due to the replacement of the core network device, thereby saving information reporting overhead.

[0247] In some embodiments, the core network device may also receive model-related information sent by the access network device. Specifically, FIG5 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The method includes:

[0248] S510. The first core network device receives fourth model related information sent by the second access network device; wherein the fourth model related information includes fifth information related to the applicable conditions of the second model in the second terminal device.

[0249] Exemplarily, the fourth model-related information can be determined based on the model-related information sent by the second terminal device and received by the second access network device, for example, the fourth model-related information is a subset of the model-related information sent by the second terminal device (including all or part of the model-related information).

[0250] Although the access network device will delete the context of the terminal device after leaving the connected state, if the second access network device sends all or part of the model-related information obtained by the second access network device to the first core network device before releasing the second terminal device back to the idle state or inactive state, this information will be saved by the first core network device and will be re-transmitted from the first core network device to the access network device for use when the second terminal device enters the connected state next time. The terminal device does not need to report the first model-related information to the access network device every time it enters the connected state, thus saving information reporting overhead.

[0251] In some embodiments, the fifth information includes one or more of the following:

[0252] The device status to which the second model applies;

[0253] Device information of the terminal device to which the second model is applicable;

[0254] Applicable condition information related to the implementation of the second model;

[0255] Configuration information applicable to the second model;

[0256] Device information of the network device to which the second model applies;

[0257] Network deployment information applicable to the second model;

[0258] The second model applies to the input data requiring information.

[0259] The content and application of the fifth information can be implemented similarly to the corresponding description of the first information in the aforementioned embodiment, and will not be repeated here.

[0260] In some embodiments, one or more of the fifth information is a string. For example, device information of a terminal device applicable to the second model is a sixth string, and / or applicable condition information related to the implementation of the second model is a seventh string, and / or device information of a network device applicable to the second model is an eighth string, and / or network deployment information applicable to the second model is a ninth string, and / or input data requirement information applicable to the first model is a tenth string.

[0261] In some embodiments, one or more of the fifth information is carried by an information container. For example, device information of a terminal device to which the second model applies is carried by a sixth information container, and / or applicable condition information related to the implementation of the second model is carried by a seventh information container, and / or device information of a network device to which the second model applies is carried by an eighth information container, and / or network deployment information to which the second model applies is carried by a ninth information container, and / or input data requirement information to which the first model applies is carried by a tenth information container.

[0262] In some embodiments, the second model-related information further includes seventh information, and the seventh information includes one or more of the following:

[0263] The identification ID of the second model;

[0264] Type information of the input parameters of the second model;

[0265] Type information of the output parameters of the second model;

[0266] Functional information of the second model.

[0267] It is understandable that the above embodiments can be implemented in combination unless they are contradictory. For example, the first core network device can receive the first model related information sent by the first terminal device, and can also receive the fourth model related information sent by the second access network device.

[0268] In some embodiments, the information transmission method may further include:

[0269] The first core network device sends fifth model related information to the third access network device; wherein the fifth model related information includes a subset of the fourth model related information.

[0270] The third access network device and the second access network device may be the same device or different devices.

[0271] Specifically, for the fourth model-related information received from the second access network device, when the second terminal device leaves the connected state and accesses the second access network device again, or when the second terminal device accesses other access network devices after performing cell switching or cell reselection, the first core network device can transmit all or part of the fourth model-related information to the second access network device or other access network devices. In this way, when the second terminal device leaves the connected state and accesses the second access network device, or when the second terminal device accesses other access network devices after performing cell switching or cell reselection, there is no need to report the model-related information to the access network device again, thereby saving information reporting overhead.

[0272] In some embodiments, the information transmission method may further include:

[0273] The first core network device sends sixth model related information to the third core network device; wherein the sixth model related information includes a subset of the fourth model related information.

[0274] That is to say, for the fourth model related information obtained from the access network device, the first core network device can also transmit the full set or subset of the fourth model related information to other core network devices. In this way, when the serving core network device of the second terminal device changes (for example, the core network device is replaced due to the mobility of the second terminal device), the continuity of the maintenance of the model related information of the second terminal device can be maintained through the information interaction between the source core network device and the target core network device, avoiding the second terminal device from reporting the model related information again due to the replacement of the core network device, thereby saving the information reporting overhead.

[0275] An embodiment of the present application also provides an information transmission method performed by an access network device. Figure 6 is a schematic flow chart of an information transmission method according to an embodiment of the present application. This method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes at least part of the following content.

[0276] S610. The fourth access network device receives first model-related information sent by the first terminal device; wherein the first model-related information includes first information related to the applicable conditions of the first model in the first terminal device.

[0277] In some embodiments, the first information includes one or more of the following:

[0278] The state of the device to which the first model applies;

[0279] Device information of the terminal device to which the first model is applicable;

[0280] Applicable condition information related to the implementation of the first model;

[0281] Configuration information applicable to the first model;

[0282] Device information of the network device to which the first model applies;

[0283] Network deployment information applicable to the first model;

[0284] The first model applies to the input data required information.

[0285] The content and application of the first information can refer to the corresponding description of the above embodiment and will not be repeated here.

[0286] In some embodiments, one or more of the first information is a string. For example, device information of a terminal device to which the first model applies is a first string, and / or applicable condition information related to the implementation of the first model is a second string, and / or device information of a network device to which the first model applies is a third string, and / or network deployment information to which the first model applies is a fourth string, and / or input data requirement information to which the first model applies is a fifth string.

[0287] In some embodiments, one or more of the first information is carried by an information container. For example, device information of a terminal device to which the first model applies is carried by a first information container, and / or applicable condition information related to the implementation of the first model is carried by a second information container, and / or device information of a network device to which the first model applies is carried by a third information container, and / or network deployment information to which the first model applies is carried by a fourth information container, and / or input data requirement information to which the first model applies is carried by a fifth information container.

[0288] In some embodiments, the first model-related information further includes second information, where the second information includes one or more of the following:

[0289] The identification ID of the first model;

[0290] Type information of the input parameters of the first model;

[0291] Type information of the output parameters of the first model;

[0292] Functional information of the first model.

[0293] In some embodiments, the information transmission method further includes the fourth access network device sending third information to the first terminal device; wherein the third information includes:

[0294] IDs of one or more models corresponding to the first model related information requested to be obtained by the fourth access network device; and / or,

[0295] First indication information, where the first indication information is used to request the first terminal device to send the first model related information.

[0296] In some embodiments, the information transmission method further includes, the fourth access network device receiving fourth information sent by the first terminal device; wherein the fourth information includes one or more of the following:

[0297] IDs of one or more models stored in the first terminal device;

[0298] IDs of one or more models updated by the first terminal device;

[0299] Second indication information, where the second indication information is used to indicate that the first terminal device contains first model related information to be reported or is used to indicate that the first model related information has been updated.

[0300] In some embodiments, the information transmission method also includes the fourth access network device sending third indication information and / or ID information of one or more models that the fourth access network device is concerned about to the first terminal device, and the third indication information is used to indicate whether the first terminal device is allowed to send information related to the first model.

[0301] In some embodiments, the information transmission method further includes, the fourth access network device receiving capability reporting information sent by the first terminal device; wherein the capability reporting information includes:

[0302] Whether the first terminal device supports sending first model related information; and / or,

[0303] The first terminal device supports sending one or more model IDs corresponding to the first model related information.

[0304] Among them, the capability reporting information, the third indication information, the fourth information and the third information can be implemented according to the corresponding description of the aforementioned embodiment, and will not be repeated here.

[0305] In some embodiments, the fourth access network device may also perform activation / deactivation / switching operations on the first model in the first terminal device based on the first model related information, or configure other models related to the first model for the first terminal device.

[0306] In some embodiments, the above information transmission method may further include:

[0307] The fourth access network device sends seventh model related information to the fourth core network device; wherein the seventh model related information includes a subset of the first model related information.

[0308] For example, the fourth access network device can execute before the first terminal device switches to an idle state or an inactive state. That is, before releasing the first terminal device back to the idle state or the inactive state, the fourth access network device sends all or part of the acquired first model related information to the fourth core network device. This information is stored by the fourth core network device and will be re-transmitted from the fourth core network device to the access network device for use when the first terminal device enters a connected state next time. This eliminates the need for the first terminal device to report the first model related information to the access network device each time it enters a connected state, thereby saving information reporting overhead.

[0309] In some embodiments, the information transmission method may further include: a fourth access network device or other access network device receiving eighth model related information sent by a fourth core network device; wherein the eighth model related information includes a subset of the seventh model related information. Optionally, the fourth access network device may receive the eighth model related information from the fourth core network device when the first terminal device re-enters the connected state.

[0310] In some embodiments, the above-mentioned information transmission method may further include: the fourth access network device sends ninth model related information to the fifth access network device; wherein, the ninth model related information includes a subset of the first model related information and / or a subset of the eighth model related information.

[0311] This means that model-related information can be transferred between two access network devices. When a terminal device's serving access network device changes (for example, due to a replacement of the access network device due to terminal device mobility), information exchange between the source and target access network devices maintains continuity in model-related information maintenance, preventing the terminal device from reporting model-related information again due to access network device replacement, thus reducing information reporting overhead.

[0312] FIG7 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0313] S710. The fourth access network device receives the tenth model-related information sent by the fifth core network device; wherein the tenth model-related information includes sixth information related to the applicable conditions of the third model in the third terminal device.

[0314] Exemplarily, the tenth model-related information can be determined based on the model-related information sent by the third terminal device and received by the fifth core network device, for example, the tenth model-related information is a subset of the model-related information sent by the third terminal device (including all or part of the model-related information).

[0315] That is to say, the third terminal device sends model-related information to the core network device, and the model-related information of the third terminal device is saved at the core network device. The terminal device does not need to report the first model-related information to the access network device every time it enters the connected state, thereby saving information reporting overhead.

[0316] Exemplarily, the fourth access network device can perform model management operations based on the information related to the tenth model, including activation / deactivation / switching processing of the third model in the third terminal device, and / or configuring other models related to the third model for the third terminal device.

[0317] In some embodiments, the above method may further include:

[0318] The fourth access network device sends eleventh model related information to the sixth access network device; wherein the eleventh model related information includes a subset of the tenth model related information.

[0319] That is, for the tenth model-related information received from the core network device, the fourth access network device can also transmit all or part of the tenth model-related information to the sixth access network device. For example, the fourth access network device is the source access network device when the service access network device of the third terminal device changes, and the sixth access network device is the target access network device when the service access network device of the third terminal device changes. Through information exchange between the source access network device and the target access network device, the continuity of model-related information maintenance is maintained, avoiding the terminal device from reporting model-related information again due to the replacement of the access network device, and saving information reporting overhead.

[0320] It can be seen that according to the embodiment of the present application, the full set or subset of model-related information reported by the terminal device can be transmitted between access network devices, between access network devices and core network devices, and between core network devices, thereby maintaining the continuity of model-related information maintenance, avoiding the need to report the first model-related information every time the terminal device changes a cell or area, and saving system information reporting overhead.
