[0084] In some embodiments, the access network device, the core network device, or the network device can be replaced by a terminal. For example, the various embodiments of the present disclosure can also be applied to a structure in which the communication between the access network device, the core network device, or the network device and the terminal is replaced by communication between multiple terminals (for example, device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, it is also possible to set the structure in which the terminal has all or part of the functions of the access network device.

[0089] Figure 1A is a functional architecture diagram of AI / ML. As shown in Figure 1A, the model ID can be used within the function and can also be used in different data / information / instruction flows to identify the AI / ML model. For example, the model ID may ultimately be associated with the selection / (de)activation / switching of the model, or with "model transmission / delivery" information.

[0090] Data collection provides input data to the model training, management, and inference modules; model training is the module that performs AI / ML model training, validation, and testing, which can generate model performance indicators as part of the model testing process; management is the function of supervising the operation (e.g., selection / (de)activation / switching / fallback) and supervision (e.g., performance) of AI / ML models or AI / ML functions; inference is the application of artificial intelligence / machine learning models or artificial intelligence / machine learning functions in the process of providing output, using data provided by data collection (i.e., inference data) as input; model storage is responsible for storing trained / updated models, which can be used to perform inference functions.

[0091] Currently, it is assumed that model IDs can be globally unique, for example, to allow for appropriate model validation and model testing procedures, and that model IDs can be used to identify AI / ML models. Each model ID can be unique. For AI or ML models, the introduction of model IDs allows for a unique model ID. However, the length of this unique ID can be very long. In AI / ML functional applications, such as AI / ML-based positioning, using a unique model ID throughout the positioning process increases signaling overhead.

[0092] Therefore, the present disclosure proposes a model identifier determination method and device, a communication system, a communication device, and a storage medium, which determine a local unique identifier based on a unique identifier and use it in a model application. The length of the local unique identifier does not have to be very long, and different models can be distinguished by only a few bits, thereby solving the problem that the use of a unique identifier will increase signaling overhead.

[0093] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G, etc.).

[0119] FIG2 is an interactive diagram of a model identification determination method provided by an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a model identification determination method, which can be executed by a communication system, such as the communication system 100 shown in FIG1B . The communication system includes a first device and a second device. For example, the communication system may also include a third device. The interactive method may include the following steps:

[0120] Step 2101: The first device sends a second identifier to the second device.

[0121] In some embodiments, the second identifier is used to uniquely identify the first model. For example, the second identifier can be used to uniquely identify the first model globally or in a specific range, which is not limited in this disclosure.

[0122] In some embodiments, the first device may send the identifier of the first device to the second device at the same time as sending the second identifier to the second device.

[0123] In some embodiments, the second identifier may be transmitted via a radio resource control RRC message, where the first device is a terminal and the second device is a base station.

[0124] In some embodiments, the second identifier may be transmitted via a media access control MAC message, where the first device is a terminal and the second device is a base station.

[0125] In some embodiments, the second identifier may be transmitted via a physical layer PHY message, where the first device is a terminal and the second device is a base station.

[0126] In some embodiments, the second identifier may be transmitted via an LTE Positioning Protocol (LPP) message, where the first device is a terminal and the second device is a Location Management Function (LMF) network element. For example, the LPP may provide capability information, request assistance information, or send an LCS (Location Service) message.

[0127] In some embodiments, the second identifier may be transmitted via a non-access stratum (NAS) message, where the first device is a terminal and the second device is an access and mobility management function (AMF) network element. For example, the second identifier may be reported by the terminal during registration.

[0128] In some embodiments, the first device may be a device for training a model or the first device may be a device for using a model, and the first device provides an identifier of the model to the second device, that is, the first device sends the second identifier to the second device.

[0129] In some embodiments, the first device may be a terminal, and the second device may be a network device; the first device may be a network device, and the second device may be a terminal.

[0130] In the above embodiment, the first device sends a unique identifier to the second device, which can serve as a basis for the second device to determine a local unique identifier.

[0131] Step 2102: The second device sends a first identifier to the first device.

[0132] In some embodiments, the first identification is determined based on the second identification.

[0133] In some embodiments, the first identifier is used to uniquely identify the first model locally on the first device.

[0134] In some embodiments, the first identifier may be an index corresponding to the second identifier. The second device determines the first identifier based on the second identifier and sends the index of the second identifier to the first device. The first device may determine the second identifier corresponding to the first identifier based on the index.

[0135] For example, the terminal sends unique identifier 1, unique identifier 2, and unique identifier 3 to the LMF, and the LMF sends local unique identifiers with indexes 1, 2, and 3 to the terminal, which means that the local unique identifier with index 1 corresponds to unique identifier 1, the local unique identifier with index 2 corresponds to unique identifier 2, and the local unique identifier with index 3 corresponds to unique identifier 3.

[0136] In some embodiments, the first identifier may be transmitted via a radio resource control RRC message, where the first device is a terminal and the second device is a base station.

[0137] In some embodiments, the first identifier may be transmitted via a media access control MAC message, where the first device is a terminal and the second device is a base station.

[0138] In some embodiments, the first identifier may be transmitted through a physical layer PHY message, where the first device is a terminal and the second device is a base station.

[0139] In some embodiments, the first identifier may be transmitted via an LTE Positioning Protocol (LPP) message, where the first device is a terminal and the second device is a Location Management Function (LMF) network element. For example, the message may be an LPP providing capability information, an LPP requesting assistance information, or an LCS (Location Service) message.

[0140] In some embodiments, the first identifier may be transmitted via a non-access stratum (NAS) message, where the first device is a terminal and the second device is an access and mobility management function (AMF) network element. For example, the first identifier may be reported by the terminal during registration.

[0141] In some embodiments, the first device can be a device for training the model or a device for using the model, and the second device sends a local identifier or a local identifier and index determined based on the identifier of the model to the first device, that is, the second device sends the first identifier to the first device.

[0142] In some embodiments, the first device may be a terminal, and the second device may be a network device; the first device may be a network device, and the second device may be a terminal.

[0143] In the above embodiment, the second device sends the first identifier to the second device through the second identifier sent by the first device. Applying this in the use process of the first model can reduce the problem of increasing signaling overhead by using a unique identifier.

[0144] In addition, in the above embodiment, the second device provides the first device with the first identifier of the first model, so that the second device can use and manage the first model more flexibly.

[0145] Step 2103: The second device sends a mapping relationship between the first identifier and the second identifier to the first device.

[0146] In some embodiments, the mapping relationship reflects a one-to-one correspondence between the first identifier and the second identifier.

[0147] For example, the second device sending [local ID1, global ID 1] to the first device indicates that local ID 1 corresponds to global ID 1. For example, in the process of model application, when the first identifier is used, the first model can be corresponded.

[0148] For example, the second device sends [local ID2, china ID 2] to the first device, which means that the local ID2 and the China ID2 are in a corresponding relationship.

[0149] The execution order of step 2103 and step 2102 is not limited, and they can be executed simultaneously, that is, the first identifier and the mapping relationship are sent simultaneously, or they can be executed separately.

[0150] Step 2104: The second device sends the first identifier to the third device. In some embodiments, the second device sends the first identifier to the third device for the third device to perform model management based on the first identifier.

[0151] In some embodiments, the second device may be a base station, and the third device may be a LMF network element and / or an AMF network element. For example, the gNB sends the first identifier to the LMF and / or AMF. For example, the base station may send the first identifier to the LMF via an NR Positioning Protocol A (NRPPa) message.

[0152] In some embodiments, the second device may be an AMF network element, and the third device may be a base station and / or a LMF network element. For example, the AMF sends the first identifier to the gNB and / or the LMF.

[0153] In some embodiments, the second device may be an LMF network element, and the third device may be a base station and / or an AMF network element. For example, the LMF sends the first identifier to the gNB and / or the AMF. For example, the identifier may be reported by the terminal during registration.

[0154] In some embodiments, the second device may send the identifier of the first device to the third device at the same time as sending the first identifier to the third device, so as to indicate that the first identifier is the first identifier corresponding to the first device.

[0155] For example, the base station manages the models of multiple terminals. The AMF sends the first identifier and the identifier of the corresponding terminal to the base station respectively. The base station can distinguish the first identifier corresponding to each terminal, thereby managing the models of these terminals.

[0156] For example, the LMF manages models for multiple terminals. The base station sends a first identifier and the identifier of the corresponding terminal to the LMF. The LMF can distinguish the first identifier corresponding to each terminal and thus manage the models of these terminals. In step 2105, the first device, the second device, and / or the third device each perform a management operation for the first model.

[0157] In some embodiments, the management operation includes at least one of model switching, model updating, model rollback, model activation, model deactivation, and model recommendation.

[0158] In some embodiments, the first device, the second device and / or the third device performs management operations related to the first model according to the first identifier.

[0159] In some embodiments, the first device, the second device and / or the third device performs management operations related to the first model according to the first identifier and the identifier of the first device.

[0160] In some embodiments, the first device, the second device, and / or the third device perform management operations related to the first model in the same manner.

[0161] The model identification determination method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2105. For example, step 2101 can be tried as an independent embodiment, step 2102 can be implemented as an independent embodiment, and so on, but is not limited to this.

This local ID / or temporary ID is allocated by the LMF, the gNB, or the AMF.

[0203] Step 1. The UE provides the unique ID of the AI ​​model / function to the LMF / gNB / AMF, including:

[0204] The message sent to LMF is LPP peovide capability message or LPP request assistance data message;

[0205] The message sent to the gNB is UAI for position or capability reporting.

[0206] The message sent to the AMF is sent via NAS message, for example, reported by the UE during the registration process.

[0207] Step 2: The LMF / gNB / AMF provides an ID, including:

[0210] Step 3: The LMF / gNB / AMF provides the above ID to the UE, including:

[0211] LMF is sent via the LPP request location information message or the LPP provide assistance data message;

[0212] The gNB sends the message via RRC messages, such as RRC reconfiguration messages;

[0213] The AMF is sent via NAS messages, for example, sent by the UE during the registration process.

[0214] Step 4: Model management, including:

[0215] The gNB sends the above ID to the LMF and / or AMF for the latter to manage the model; for example, the base station may send it to the LMF via the NR positioning protocol A (NRPPa) message.

[0216] The AMF sends the above ID to the gNB and / or LMF for the latter to manage the model;

[0217] The LMF sends the above ID to the gNB and / or AMF for the latter to manage the model.
