The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0262] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0263] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0264] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, Open Radio Access Network (O-RAN) systems, systems utilizing other resource determination methods, and next-generation systems based on and extended from these systems, such as the sixth-generation mobile communication system (6G). Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0265] FIG2 is one of the interactive schematic diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0266] Step 201: The terminal device stores measurement information corresponding to the target cell corresponding to the mobility operation according to the type of the mobility operation; the measurement information includes at least one of measurement event related information and execution condition information.

[0267] Exemplarily, when the terminal device determines to perform a mobility operation, the target cell measurement information corresponding to the mobility operation is stored according to the type of the mobility operation, including storing the measurement information corresponding to the target cell corresponding to the mobility operation.

[0268] To support handover failure prediction and other handover performance optimization-related predictions, such as handover target cell prediction and measurement result prediction, the UE needs to collect handover-related data for prediction model training and record this data. Furthermore, network equipment does not store each UE's mobility-related data for a long period of time. Therefore, to support network equipment training of AI prediction models, the UE needs to report this information to the network. The prediction model can be based on AI (Artificial Intelligence) or ML (Machine Learning).

[0269] Based on the existing reporting process, the UE can report some useful information, such as measurement results. If the AI / ML model is trained through network equipment, the UE is required to report the collected (also called recorded, stored, etc.) data to the network. In order to avoid frequent reporting of collected data, the UE can store multiple collected data locally and report all stored data to the network in one reporting process. The UE can also report the corresponding data to the network each time it collects data.

[0270] However, for predictions related to handover performance optimization, relying solely on measurement results is not accurate enough. In order to generate a better prediction model for HOF (HO failure) prediction (or other prediction models related to handover performance optimization), the UE needs to collect more types of handover-related data and report them to the network device.

[0271] For predictions related to handover performance optimization (e.g., HOF prediction models, measurement parameter optimization models, and mobility trigger event optimization models), the type and parameters of mobility management events influence the generation and training of these models. In some cases, the event type and parameters can serve as input to these models, and different event types can correspond to different prediction models. Some prediction models may only be applicable to mobility operations based on specific events.

[0272] In the embodiments of the present disclosure, in order to improve the accuracy of training results, a method is proposed in which the UE records and reports event-related information corresponding to the mobility operation, so as to further improve the existing reporting mechanism.

[0273] Optionally, the mobility operation may include but is not limited to one or more of the following mobility operations: traditional handover HO, PSCell addition (primary cell or secondary cell addition), PSCell change (primary cell or secondary cell change), CHO (Conditional Handover, conditional triggered handover), CPAC (conditional PSCell addition or change, conditional primary and secondary cell addition or change), LTM (L1 / L2 triggered Mobility, layer 1 / layer 2 triggered mobility), conditional triggered LTM (conditional LTM, which can be referred to as CLTM), CPA (conditional PSCell change, conditional primary and secondary cell addition), CPC (conditional PSCell addition, conditional primary and secondary cell change), Subsequent CPC (subsequent conditional primary and secondary cell change), CHO with target SCG (conditional triggered handover associated with target secondary cell group), CHO with candidate SCG(s) (conditional triggered handover associated with candidate secondary cell group), DAPS (Dual Active Protocol Stack, dual active protocol stack handover), etc.

[0274] Optionally, CHO refers to a handover performed by the UE when one or more handover execution conditions are met. After receiving the CHO configuration, the UE starts evaluating the execution conditions and stops evaluating the execution conditions after performing a handover (including legacy handover (normal handover) and CHO). CHO is applicable to the following criteria:

[0275] (1) CHO configuration includes CHO candidate cell configuration and execution conditions. One execution condition may include one or two trigger conditions (e.g., CHO event A3 / A5).

[0276] Among them, CondEvent A3 (CHO event A3): Conditional reconfiguration candidate becomes an amount of offset better than PCell / PSCell [phase becomes better than PCell (primary cell) / PCells (primary cell group), conditional reconfiguration candidate has a better offset]; CondEvent A5 (CHO event A5): PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2 PCell / PSCell [(primary and secondary cells) become worse than absolute threshold 1, and the conditional reconfiguration candidate becomes better than another absolute threshold 2];

[0277] (2) Before any CHO execution conditions are met, if the UE receives a HO (without CHO configuration) command, it will perform the traditional HO procedure regardless of any CHO configuration received previously.

[0278] (3) When performing CHO, that is, from the time the UE starts synchronizing with the target cell (target gNB), the UE does not monitor the source cell (e.g., source gNB).

[0279] Optionally, CPAC can be divided into CPA and CPC. CPC is a PSCell change executed by the UE when the execution condition is met. Upon receiving the CPC configuration, the UE starts evaluating the execution condition, and stops evaluating the execution condition once a PSCell change or PCell change is triggered. (A Conditional PSCell Change (CPC) is defined as a PSCell change that is executed by the UE when execution condition(s)is met. The UE starts evaluating the execution condition(s)upon receiving the CPC configuration, and stops evaluating the execution condition(s)once PSCell change or PCell change is triggered.)

[0280] Optionally, LTM (L1 / L2 triggered Mobility) means that the gNB receives L1 measurement report(s)from a UE, and on their basis the gNB changes UE serving cell by a cell switch command signaled via a MAC CE.The cell switch command indicates an LTM candidate configuration that the gNB previously prepared and provided to the UE through RRC signaling.Then the UE switches to the target configuration according to the cell switch command.The LTM procedure can be used to reduce the mobility latency. (LTM (L1 / L2 triggered Mobility) is a procedure in which a gNB receives L1 measurement report(s)from a UE,and on their basis the gNB changes UE serving cell by a cell switch command signaled via a MAC CE.The cell switch command indicates an LTM candidate configuration that the gNB previously prepared and provided to the UE through RRC signaling.Then the UE switches to the target configuration according to the cell switch command.The LTM procedure can be used to reduce the mobility latency.)

[0281] Optionally, LTM can be divided into three types: MCG LTM (Master Cell group L1 / L2 triggered Mobility, L1 / L2 triggered main cell group mobility switching; MCG is Master Cell group, main cell group mobility switching), SCG LTM (Secondary Cell group L1 / L2 triggered Mobility, L1 / L2 triggered secondary cell group mobility switching; SCG is Secondary Cell group, secondary cell group mobility switching), and / or, three types of LTM for MCG and SCG mobility. Exemplarily, LTM can also be an LTM based on conditional triggering, and the LTM based on conditional triggering can be called any one or more of Conditional LTM, CLTM, and C-LTM.

[0282] Optionally, the measurement information corresponding to the target cell corresponding to the mobility operation may be determined according to the type of the mobility operation.

[0283] Optionally, the types of mobility operations may be divided into two types according to triggering reasons of the mobility operations: mobility operations triggered by network devices and mobility operations triggered based on conditions.

[0284] Optionally, the mobility operation triggered by the network device may include but is not limited to HO, PSCell addition, PSCell change, LTM, and DAPS. Correspondingly, the measurement information corresponding to the target cell corresponding to the mobility operation triggered by the network device may include: information about a measurement event corresponding to the target cell.

[0285] Exemplarily, the measurement information corresponding to the target cell corresponding to the mobility operation triggered by the network device may include: information on a measurement event corresponding to the target cell when the mobility operation triggered by the network device is executed.

[0286] Exemplarily: the measurement information corresponding to the target cell corresponding to the mobility operation triggered by the network device may include: information on the measurement event corresponding to the target cell before executing the mobility operation triggered by the network device, for example, information on the measurement event corresponding to the most recent measurement report containing the measurement results of the target cell.

[0287] Optionally, the conditionally triggered mobility operation may include, but is not limited to, CHO, CPAC, CPA, CPC, CLTM, CHO with target SCG, CHO with candidate SCG(s), Subsequent CHO, and Subsequent CPAC. Correspondingly, the measurement information corresponding to the target cell corresponding to the conditionally triggered mobility operation may include: information about the execution conditions when the terminal device performs the conditionally triggered mobility operation.

[0288] Exemplarily, the measurement information corresponding to the target cell corresponding to the mobility operation triggered based on the condition may include one or more of the following information, when the terminal device performs the mobility operation triggered based on the condition:

[0289] Information on the execution conditions corresponding to the target cell,

[0290] Information on the execution conditions corresponding to the target cell,

[0291] Information on execution conditions corresponding to candidate cells corresponding to conditionally triggered mobility operations.

[0292] Optionally, the measurement information corresponding to the target cell corresponding to the mobility operation triggered based on the condition may also include: information on the measurement event corresponding to the candidate target cell.

[0293] Optionally, the network device may be a serving cell (e.g., source gNB, master node (MN), secondary node (SN)).

[0294] Optionally, referring to Figure 3, taking the mobility operation as a traditional handover HO as an example, the inter-gNB handover process may include: in step 3-1, the UE performs measurement reporting based on the configuration of the network device [for example, the mobility control information provided by the AMF (Access and Mobility Management Function) in 3-0]; in step 3-2, the source gNB determines to hand over to the target cell (target gNB) based on the measurement results reported by the UE; in step 3-6, the source gNB sends a handover command (RAN handover initiation) carrying the target cell configuration to the UE; when the UE receives an RRC Reconfiguration message containing the handover information, the UE will immediately execute the corresponding handover process according to the received RRC message.

[0295] Optionally, referring to Figure 4, taking CHO as an example of a mobility operation, the inter-gNB handover process may include: in step 4-1, the UE performs measurement reporting based on the configuration of the network device [for example, the mobility control information provided by the AMF (Access and Mobility Management Function) in step 4-0]; in step 4-2, the source gNB determines one or more candidate target cells for CHO and corresponding execution conditions based on the measurement results reported by the UE, and in step 4-6, sends the CHO configuration carrying the candidate target cell configuration and execution conditions to the UE. When the UE receives the RRC Reconfiguration message containing the CHO configuration, the UE evaluates the corresponding execution conditions. When the execution conditions corresponding to a candidate cell are met, the UE triggers CHO, applies the corresponding candidate cell configuration, and accesses the corresponding candidate target cell.

[0296] Optionally, referring to Figure 5, taking the mobility operation as LTM (specifically MCG LTM) as an example, the inter-gNB handover process may include: in step 5-1, the UE sends a measurement report to the gNB; in step 5-2, the gNB performs RRC reconfiguration based on the measurement report sent by the UE, and sends an RRC reconfiguration message to the UE; in step 5-3, the UE sends an RRC reconfiguration completion message to the gNB; in steps 5-4a and 5-4b, uplink and downlink synchronization of the LTM candidate cell are performed; in step 5-5, the UE sends an L1 measurement report to the gNB; in step 5-6, the gNB sends an LTM cell handover command to the UE through a MAC CE (Medium Access Control Control Element); the UE separates from the source cell and applies the target cell configuration information; in step 5-7, a random access channel process is performed to access the corresponding target cell.

[0297] Optionally, when the terminal device stores the measurement information corresponding to the target cell corresponding to the mobility operation, it can specifically include: when the terminal device determines that the terminal device performs the mobility operation and has not accessed the target cell, the measurement information corresponding to the target cell is stored (i.e., failure data), and the measurement information is marked as associated with the mobility operation switching failure (or execution failure); or, when the terminal device determines that the terminal device performs the mobility operation and accesses the target cell, the measurement information data corresponding to the target cell (i.e., success information) is stored, and the measurement information is marked as associated with the mobility operation switching success (or execution success).

[0298] Optionally, the terminal device can passively store the measurement information corresponding to the target cell (for example, based on the configuration or instruction of the network device, store the measurement information corresponding to the target cell); or actively store the measurement information corresponding to the target cell (for example, based on protocol provisions or the UE's own needs, store the measurement information corresponding to the target cell). The embodiments of the present disclosure do not limit this.

[0299] Optionally, when the terminal device passively stores measurement information corresponding to the target cell, the terminal device may store the measurement information based on storage configuration information sent by the network device; or may store the measurement information based on storage indication information sent by the network device. The storage configuration information is used to request the terminal device to store the measurement information; and the storage indication information instructs the terminal device to store the measurement information.

[0300] Optionally, when the network device sends storage configuration information to the terminal device, it can specifically request the terminal device to store the measurement information corresponding to the target cell when the mobility operation is successfully executed; it can also request the terminal device to store the measurement information corresponding to the target cell when the mobility operation fails to switch.

[0301] Similarly, when the network device sends storage indication information to the terminal device, it can specifically instruct the terminal device to store the measurement information corresponding to the target cell when the mobility operation is successfully executed; it can also instruct the terminal device to store the measurement information corresponding to the target cell when the mobility operation fails to switch.

[1157] With respect to the foregoing record, when the terminal device stores the measurement information corresponding to the target cell corresponding to the mobility operation, it is mainly stored according to the type of mobility operation, and the type of mobility operation may include a mobility operation triggered by a network device and a mobility operation triggered based on a condition, and for different types of mobility operations, the stored measurement information corresponding to the target cell corresponding to the mobility operation is also different. The following describes the two storage methods in detail:

[1158] Method 1: Recording information about measurement events satisfied by the handover target cell (applicable to mobility operations triggered by network equipment, and described below using HO as an example).

[1170] 6 Based on 4, in response to the handover target cell not being any cell that triggers measurement reporting, the UE includes indication information in the log data corresponding to the handover, indicating that the handover target cell is not associated with any measurement reporting event;

[1171] 7 Based on 1, in response to the handover target cell being any cell that triggers measurement reporting, the UE records data related to the handover.

Specifically, when the UE satisfies execution condition A associated with a candidate cell A (or candidate cell configuration), and the UE executes CHO / CLTM to initiate access to cell A (hereinafter referred to as the handover target cell), the UE records the configuration of execution condition A.
