[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202411001434.3, filed on July 24, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of communication, and in particular to an information configuration method and node, a storage medium, and a computer program product. BACKGROUND

[0004] For mobility optimization scenarios, the 5th Generation Mobile Communication Technology (5G) New Radio (NR) introduces a terminal trajectory prediction within the next base station range in the NR single connection scenario, which can make the target node reserve transmission resources in advance through Artificial Intelligence (AI) / Machine Learning (ML) model prediction. On the other hand, the source node obtains the real terminal trajectory from the target node as feedback data to update the AI / ML model.

[0005] In order for the target node to start and stop the above acquisition behavior in time, 5G NR defines four trigger conditions for stopping the above acquisition behavior. However, the trigger conditions of NR single connection cannot be applied to the terminal dual connection state, which will cause the node to perform unnecessary measurement or collection behavior, or the measured or collected information is not suitable for the dual connection scenario, thereby causing low measurement or collection efficiency and low adaptability of the dual connection scenario.

[0044] In order to enable more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below, and the attached drawings are only used for reference and are not intended to limit the embodiments of the present application.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing the embodiments of the present application only and is not intended to limit the present application.

[0046] In the following description, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict. It should be noted that the terms "first, second, third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order of the objects. It can be understood that "first, second, third" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0047] For mobility optimization scenarios, 5G NR first introduces the prediction of the moving trajectory of the terminal within the next hop base station range in the NR single connection scenario, that is, the source node with AI / ML capability uses the AI model inference module to predict the moving trajectory of a specific terminal. The source node sends the predicted trajectory information to the target node, which can directly use the prediction information to reserve transmission resources in advance. On the other hand, in order to continuously update the AI / ML model, the source node also needs to obtain the real terminal moving trajectory from the target node as feedback, which can be used to monitor the performance of the AI / ML model output and retrain the AI / ML model in time to continuously improve the prediction and decision performance of the AI / ML model. Among them, in order for the target node to start and stop the measurement / acquisition behavior of the terminal moving trajectory in time and start reporting in time, the 5G NR specification defines the cell to which the successful handover to the target node is included to start the measurement / acquisition of the terminal moving trajectory, and defines four trigger conditions for stopping the measurement / acquisition of the terminal moving trajectory, that is, the target node stops measurement / acquisition when one of the trigger conditions is met, and the specific trigger conditions are:

[0048] 1. The acquisition time window expires;

[0049] 2. The number of handovers between cells in the range of the target node reaches a threshold value;

[0050] 3. The terminal enters a radio resource control (RRC) inactive state or an RRC idle state;

[0051] 4. The terminal leaves the current node cell and switches to other target node.

[0052] On the basis of single connection mobility optimization, 5G NR plans to optimize terminal mobility in the dual connection scenario of NR-dual connectivity (DC). However, if the single connection scenario related mechanisms and processes are directly extended to the dual connection scenario of NR-DC, there will be problems of inapplicability. For example, the above-mentioned part of the triggering conditions for stopping measurement / collection cannot work in the dual connection scenario, such as the RRC connection state is always maintained in the dual connection scenario, and the terminal will not enter the RRC deactivation state or the RRC idle state; or in the scenario of master node (MN) initiating secondary node (SN) change, there is no behavior of terminal switching between cells within the range of target node. In addition, the dual connection scenario is more complex than the single connection scenario. For example, the terminal supporting dual connection will change between dual connection and single connection according to the transmission demand of data volume, and there will also be a situation of secondary cell group (SCG) deactivation in dual connection. Therefore, when the terminal enters dual connection or the terminal changes between various states in dual connection, the related mechanisms of starting and stopping the measurement of terminal moving track or the measurement / collection behavior of terminal performance and timely starting the report also need to be considered, but the existing technology cannot support it, which may cause unnecessary measurement / collection behavior of the node (such as target SN), or a large amount of measurement / collection information is not applicable to the dual connection scenario, and cannot meet the demand of AI model performance monitoring and iterative optimization.

[0053] Embodiments of the present application provide an information configuration method, as shown in FIG. 1, applied to a source MN, which can include:

[0054] S101, send first information to the first node, the first information carries at least one of the following: first configuration or indication information; the first configuration or indication information is used to indicate the first node to stop, suspend and / or resume the measurement operation and / or recording operation and / or collection operation for terminal information, the terminal information includes terminal trajectory information and / or terminal performance information; second configuration or indication information, used to indicate the first node to measure and / or record and / or collect terminal performance information; or indicate whether the first node measures and / or records and / or collects terminal performance information; third configuration or indication information, used to indicate the first node to measure and / or record and / or collect terminal performance information and terminal trajectory information; or indicate whether the first node measures and / or records and / or collects terminal performance information and terminal trajectory information; fourth configuration or indication information, used to indicate the first node to record and / or collect measured and / or real terminal performance information and data amount information; and / or indicate the first node to feed back measured and / or real terminal performance information and data amount information.

[0055] The information configuration method provided by the embodiments of the present application is suitable for the measurement and / or collection related configuration and triggering mechanism of terminal trajectory information and / or terminal performance information in a dual connectivity multi-radio (MR)-DC scenario (such as NR-DC). The problem that the existing AI / ML technology cannot be applied to terminal mobility in the dual connectivity MR-DC scenario can be solved.

[0056] In the embodiments of the present application, the first information is related configuration information or signaling used by the source MN to collect and / or obtain terminal information.

[0057] In the embodiments of the present application, the first configuration or indication information includes at least one of the following:

[0058] If the terminal falls back to a single connection state, the first node stops measuring and / or recording and / or collecting terminal information; or the first node stops measuring and / or recording and / or collecting terminal information and sends second information to the source MN;

[0059] If the terminal enters a secondary cell group (SCG) deactivation state, the first node suspends measuring and / or recording and / or collecting terminal information; or the first node suspends measuring and / or recording and / or collecting terminal information and sends second information to the source MN;

[0060] If the first duration of the terminal in the SCG deactivation state exceeds a first value, the first node stops measuring and / or recording and / or collecting terminal information; or the first node stops measuring and / or recording and / or collecting terminal information and sends second information to the source MN;

[0061] The terminal enters an SCG activation state, or a first duration in which the terminal is in an SCG deactivation state does not exceed a first value, the first node resumes measurement and / or recording and / or collecting terminal information, or the first node resumes measurement and / or recording and / or collecting terminal information and sends second information to the source MN.

[0062] In the embodiments of the present application, the first node is a target MN, a target SN, or a source SN. Specifically, it can be selected according to actual conditions, and the embodiments of the present application do not make specific limitations.

[0063] It should be noted that the target MN, the target SN, or the source SN can include an NG-RAN node, and specifically can be a base station.

[0064] In the above embodiments, the terminal falls back to a single connection state, which is an SN release (MN / SN initiated) procedure. For example, the target SN receives a secondary gNode (SgNB) release request message sent by the source MN, at which time the terminal falls back to a single connection state.

[0065] In the above embodiments, the terminal enters an SCG deactivation state under a certain primary cell (PCell) and primary secondary cell (PSCell) combination.

[0066] In the above embodiments, a timer is pre-set, the timer is started when the terminal enters an SCG deactivation state, and the timer is stopped when the terminal enters an SCG activation state. The timer can be set in the target MN or the target SN. The duration of the timer is the first duration.

[0067] In the above embodiments, the first value can be a preset duration of the timer, and the first value can also be a proportional value of the preset duration.

[0068] For example, if the preset duration of the timer is 10s, in one embodiment, when the first duration exceeds 10s, the first node stops measurement and / or recording and / or collecting terminal information, or the first node stops measurement and / or recording and / or collecting terminal information and sends second information to the source MN. In another embodiment, 80% of the preset duration, i.e., 8s, is set, and when the first duration exceeds 8s, the first node stops measurement and / or recording and / or collecting terminal information, or the first node stops measurement and / or recording and / or collecting terminal information and sends second information to the source MN.

[0069] It should be noted that the value of the first value can be set by the source MN or defined in a protocol, and specifically can be selected according to actual conditions, and the embodiments of the present application do not make specific limitations.

[0070] In the above embodiments, under a certain PCell and PSCell combination, the terminal enters the SCG activation state, or the first duration of the terminal in the SCG deactivation state does not exceed the first value, the first node resumes measurement and / or records and / or collects terminal information; or the first node resumes measurement and / or records and / or collects terminal information and sends second information to the source MN.

[0072] It should be noted that the second configuration or indication information and the third configuration or indication information can use true / false to indicate whether related information needs to be recorded and / or fed back; or use a measurement ID (measurement ID) method, and the presence of a measurement ID indicates that the first node needs to feed back related information.

[0073] It should be noted that the fourth configuration or indication information can use a bitmap method, and different bits are set to 1 or true to indicate whether the corresponding information needs to be recorded and / or fed back.

[0074] It should be noted that the second information, as the related feedback information of the real and / or measured terminal information fed back by the target node, can be used for AI / ML model training, inference or performance detection.

[0075] It can be understood that the present proposal provides trigger conditions for indicating the first node to stop and / or suspend, resume measurement / record / collect terminal information, and / or report / feedback related information according to the state specific to the dual connectivity scenario (for example, SCG activation / deactivation), solves the problem that the prior art can cause the first node to perform unnecessary measurement / collection behavior, or a large amount of measurement / collection information is not suitable for the dual connectivity scenario, and cannot meet the demand of AI model performance monitoring and iterative optimization.

[0076] In the embodiments of the present application, the source MN also generates third information, and the third information is prediction information for terminal information in the dual connectivity state of the terminal.

[0077] It should be noted that the generation of the third information in the embodiments of the present application is applicable to sub-scenarios such as SN addition (MN initiation), MN / SN initiated SN change, inter-MN handover, etc.

[0078] In the embodiments of the present application, the third information is output information of the AI and / or ML model. The AI and / or ML model can be located in the source MN, operation administration and maintenance (OAM), or other network elements independent of the source MN and the OAM.
