[0190] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0191] In some embodiments, the core network equipment can be a single device, including a first network element, a second network element, etc., or it can be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0192] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of this disclosure are also applicable to similar technical problems.

[0193] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0194] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0195] In some embodiments, as shown in FIG1B, the communication system may adopt a DC (Dual Connectivity) architecture, including two cell (or cell group) groups:

[0196] MCG: Corresponds to the network-side MN (Master Node);

[0197] SCG: Corresponds to SN (Secondary Node) on the network side;

[0198] MCG consists of one PCell and one or more SCells (Secondary Cells). SCG consists of one PSCell (Primary Secondary Cell) and one or more SCells. PCell and PSCell can be collectively referred to as SpCell (Special Cell).

[0199] In some embodiments, there is a cell within the MCG used to initiate initial access; this cell is called the PCell. The PCell is the most "primary" cell within the MCG. The PCell and SCell within the MCG are combined via carrier aggregation (CA). In the MCG, the primary cell is the PCell, and the secondary cell is the SCell; in the SCG, the primary and secondary cells are the PSCell, and the secondary cell is the SCell. Because much signaling is transmitted only on the PCell and PSCell, optionally, the PCell and PSCell can be collectively referred to as sPCell.

[0200] In some embodiments, NG-RAN supports NR-NR DC (NR-DC), where a UE connects to one gNB acting as the MN and another gNB acting as the SN. The primary gNB connects to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also connect to the 5GC via the NG-U interface. Furthermore, NR-DC can also be used for a UE to access a single gNB, acting as both the MN and SN, and simultaneously configuring both the MCG and SCG.

[0201] In some embodiments, for dynamic cell (or cell group) changes, the network side can provide the terminal with one or more candidate configurations, where one candidate configuration may include one or more "cells (or cell groups)". The network side can subsequently control the terminal to change among the multiple "candidate configurations" (e.g., changing the working cell (or cell group) from "cell (or cell group)-1" to "cell (or cell group)-2") via L1 (e.g., DCI (Downlink Control Information)) or L2 (MAC CE (Control Element)) signaling. This control signaling can be called "cell change control signaling".

[0202] This process can also be called the network-triggered LTM (L1 / L2-triggered Mobility) process.

[0203] In some embodiments, LTM refers to a process of PCell / PSCell cell switching triggered by MACCE based on L1 measurements in a network, which may be accompanied by changes in MCG and / or SCG.

[0204] In some embodiments, during LTM, the gNB can receive an L1 measurement report from the UE. Based on this, the gNB changes the UE's serving cell via a cell switch command issued by the MAC CE. The cell switch command indicates an LTM candidate cell configuration that the gNB has pre-provided to the UE via RRC signaling. The UE accesses the target cell indicated in this cell switch command according to the received cell switch command. LTM can be used to reduce mobility latency.

[0205] Optionally, LTM candidate cell configurations can only be added, modified, and released by the network via RRC signaling. The LTM process can be used to reduce mobility latency.

[0206] In some embodiments, subsequent LTM can be supported, whereby after a mobility operation is performed, the UE does not voluntarily delete the LTM configuration information. The LTM configuration information can continue to be used to trigger subsequent LTMs (Subsequent LTM) even without RRC reconfiguration and updates.

[0207] In some embodiments, LTM can be configured with LTM configuration information via LTM-Config.

[0208] Optionally, the LTM configuration information may include, but is not limited to, one or more of the following: LTM reference configuration (LTM candidate configuration); one or more candidate cell configurations (candidate cell configurations can be added, modified, or deleted through ltm-CandidateToReleaseList and ltm-CandidateToAddModList); LTMCSI resource configuration, etc.

[0209] Optionally, the candidate cell configuration can be configured via LTM-Candidate, which includes, but is not limited to, one or more of the following: candidate configuration identifier; candidate cell identifier; candidate configuration (represented by RRCReconfiguration), etc.

[0210] In some embodiments, L1 measurements of LTM can support both intra-frequency and inter-frequency L1 measurements. Semi-persistent and periodic reporting on PUSCH and on PUCCH can also be supported.

[0211] In some embodiments, one or more of the following may also be supported: CSI-RS measurement; L1-SINR measurement; event-triggered L1 measurement reporting; current L1 measurement enhancement.

[0212] Optionally, the LTM Cell Switch Command is generated by the S-DU. In the LTM of the Intra-CU, the Source gNB-DU makes the Cell switch decision, and the S-gNB-DU makes the Cell Switch decision based on the L1 measurement results reported by the UE to determine the trigger for LTM access to the candidate target cell. Then, the S-gNB-DU sends the Cell switch command to the UE.

[0213] In some embodiments, for a condition-triggered mobility procedure, the terminal can base its actions on a network-preconfigured condition and a corresponding preconfigured cell (or cell group). When the terminal meets the preconfigured condition (e.g., a specific measurement event), the terminal changes its serving cell (or cell group) to the preconfigured cell (or cell group). This condition-triggered mobility procedure includes:

[0214] CHO (Conditional Handover);

[0215] CPA (Conditional PSCell Addition, adding primary and secondary cells under certain conditions);

[0216] CPC (Conditional PSCell Change), etc.;

[0217] Optionally, the terminal may also change the configuration of a specific cell (or cell group) after the "pre-configured conditions" are met, according to network instructions. (For example, changing the terminal's PCell configuration from candidate cell (or cell group) configuration-1 to candidate cell (or cell group) configuration-2).

[0218] In some embodiments, the "condition-triggered mobility process" further includes: Conditional LTM. Optionally, condition-triggered LTM can be used for MCG changes and SCG changes.

[0219] The following is an introduction to some condition-triggered mobility features:

[0220] Conditional handover (CHO) refers to a handover performed by the UE when one or more handover execution conditions are met. The UE begins evaluating the execution conditions after receiving a CHO configuration and stops evaluating the execution conditions after performing a handover (including legacy handover and CHO).

[0221] Optionally, the CHO configuration includes the CHO candidate cell configuration and execution conditions. Optionally, an execution condition may include one or two triggering conditions.

[0222] Optionally, if the UE receives an HO (without CHO configuration) command before any CHO execution conditions are met, it executes the legacy HO procedure, regardless of any previously received CHO configuration.

[0223] Optionally, when performing a CHO, i.e., from the time the UE begins synchronizing with the target cell, the UE does not monitor the source cell.

[0224] Conditional PSCell Addition (CPA) means that the UE performs a PSCell addition when the execution conditions are met. The UE begins to evaluate the execution conditions when it receives the CPA configuration, and stops evaluating the execution conditions once a PSCell addition or PSCell change is triggered.

[0225] Optionally, CPA is triggered by MN, and the execution conditions of CPA are generated by MN, corresponding to the measurement configuration associated with MCG.

[0226] Optionally, Conditional PSCell Change (CPC) means that the UE performs a PSCell change when the execution conditions are met. After receiving the CPC configuration, the terminal begins to evaluate the execution conditions, and stops evaluating the execution conditions once the PCell changes or a PCell change is triggered.

[0227] Optionally, it can support inter-SN CPC initiated by SN without MN participation, and intra-SN CPC initiated by MN or SN.

[0228] In some embodiments, CPA and CPC can be collectively referred to as CPAC (Conditional PSCell Addition or Change).

[0229] In some embodiments, considering Conditional Handover (CHO) and Conditional PSCell Change (CPC) / Conditional PSCell Addition (CPA), a UE configured with CHO / CPC / CPA must release its CHO / CPC / CPA configuration upon completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize CHO / CPC / CPA, the terminal will have no opportunity to continue executing CHO / CPC / CPA. This increases handover or SCG change latency and signal overhead, especially in FR2 scenarios with frequent CG changes. Therefore, it is necessary to study subsequent CHO / CPAC.

[0230] Subsequent CPAC refers to the conditional PSCell addition or change process executed based on the pre-configured subsequent CPAC configuration of the candidate PSCell after PSCell addition, PSCell modification, or SCG release, without requiring reconfiguration and restart of CPC / CPA during this process.

[0231] For subsequent CPAC, after the UE performs one or more operations such as adding a PSCell, changing a PSCell, releasing an SCG, or changing a PCell, the UE will not automatically delete the corresponding conditional reconfiguration information, unlike legacy CPAC.

[0232] In some embodiments, when the UE performs a mobility operation, the UE stops evaluating the execution conditions for condition-triggered mobility (e.g., condition-triggered LTM, CLTM). Alternatively, in response to the UE receiving an indication message from the serving cell, the indication message instructing the UE to stop evaluating the execution conditions for condition-triggered LTM.

[0233] The evaluation of the conditions for UE to stop CLTM execution includes stopping the measurement of the target cell (or candidate cell), which can be either L1 measurement or L3 measurement.

[0234] In some embodiments, condition-triggered LTM may also be referred to as conditional LTM, etc.

[0235] In some embodiments, a condition-triggered LTM (Conditional LTM) can be expressed as CLTM, C-LTM, or ConditionalLTM, and / or a subsequent condition-triggered LTM (Subsequent Conditional LTM) can be expressed as SubsequentCLTM, SubsequentC-LTM, or SubsequentConditionalLTM.

[0236] In some embodiments, a condition-triggered LTM includes subsequent condition-triggered LTMs; or, a condition-triggered LTM supports subsequent condition-triggered LTMs.

[0237] It should be noted that in this disclosure, condition-triggered LTM, conditional LTM, CLTM, C-LTM, and ConditionalLTM can all represent condition-triggered LTM, and this disclosure does not limit them.

[0238] It should be noted that in this disclosure, subsequent (Subsequent) condition-triggered LTM, subsequent (Subsequent) conditional LTM, subsequent CLTM, subsequent C-LTM, and subsequent ConditionalLTM can all represent subsequent (or continuing, continuous, and persistent) condition-triggered LTMs, and this disclosure does not impose any limitations.

[0239] In some embodiments, when the UE successfully accesses the target cell, the UE initiates the evaluation of the execution conditions for CLTM, including one or more of the following: when the UE successfully accesses the target cell (e.g., the UE sends an RRC reconfiguration complete message to the target cell), the UE initiates the evaluation of the execution conditions for Subsequent C-LTM; in response to the UE receiving an indication message sent by the serving cell (i.e., the target cell that has already been accessed), the indication message is used to instruct the UE to initiate the evaluation of the execution conditions for CLTM; when the measurement result of the serving cell (i.e., the target cell that has already been accessed) is less than a first threshold value, the UE initiates the evaluation of the execution conditions for CLTM.

[0240] In some embodiments, the configuration method for condition-triggered mobility (applicable to Condition LTM, Conditional handover, and Conditional PSCell Addition and Change) may be as follows:

[0241] The network side provides the terminal side with one or more "candidate configurations" (e.g., "candidate configurations" provided through RRCReconfiguration messages, where one "candidate configuration" may include one or more "cell (or cell group) configurations");

[0242] The “candidate configuration” can be used for at least one of the following purposes: Purpose 1: The network side can subsequently change the configuration of multiple “candidate cells (or cell groups)” through signaling control terminals (e.g., “dynamic cell (or cell group) change” in the background technology); Purpose 2: When the terminal meets the triggering conditions agreed upon by the network configuration or protocol, it will change the configuration to the candidate cell (or cell group) configuration (e.g., when the terminal measurement meets the measurement event A3 or A4 or A5, it will change the configuration of the serving cell (or cell group) to the corresponding candidate cell (or cell group)).

[0243] The triggering conditions may include triggering events corresponding to cell-level measurement results based on L3 measurements, and / or triggering events based on beam-level measurement results based on L1 measurements.

[0244] In some embodiments, the triggering event corresponding to the cell-level measurement result based on L3 measurement and the triggering event corresponding to the beam-level measurement result based on L1 measurement may include at least one of the following events:

[0245] Conditional Event (CondEvent) A3: The signal quality of the candidate cell for conditional reconfiguration is better than that of PCell / PSCell by a specified offset;

[0246] Conditional event A4: The signal quality of the conditional reconfiguration candidate cell is better than the absolute threshold. Under conditional event A4, the current PSCell (even if it is configured as a conditional reconfiguration candidate cell evaluated by conditional event A4) can be used for CHO in a scenario with candidate SCG.

[0247] Conditional event A5: The signal quality of PCell / PSCell deteriorates to below absolute threshold 1, and the signal quality of the conditional reconfiguration candidate cell is better than another absolute threshold 2;

[0248] Conditional event D1: The distance between the UE and the reference location referenceLocation1 increases beyond the configured threshold distanceThreshFromReference1, and the distance between the UE and the reference location referenceLocation2 of the conditional reconfiguration candidate cell decreases beyond the configured threshold distanceThreshFromReference2.

[0249] Conditional event D2: The distance between the UE and the mobile reference location determined based on the moving reference location and its corresponding satellite ephemeris and SIB19 broadcast reference time increases beyond the configured threshold distanceThreshFromReference1, and the distance between the UE and the mobile reference location determined based on the reference location referenceLocation2 of the conditional reconfiguration candidate cell decreases beyond the configured threshold distanceThreshFromReference2.

[0250] LTM Event 2: The beam signal quality of the serving cell deteriorates to below the absolute threshold;

[0251] LTM Event 3: The beam signal quality of the candidate cell is better than that of the serving cell by a specified offset;

[0252] LTM Event 4: The beam signal quality of the candidate cell is better than the absolute threshold;

[0253] LTM Event 5: The beam signal quality of the serving cell deteriorates to below absolute threshold 1, and the beam signal quality of the candidate cell is better than another absolute threshold 2.

[0263] In some embodiments, since LTM supports subsequent LTM by default, Conditional LTM may also support subsequent LTM by default. Therefore, if the initiation and termination of CLTM execution condition evaluation are not specified, the UE may initiate the next CLTM before completing the currently triggered LTM. Such CLTM triggered during handover is inaccurate and introduces additional interruptions. Furthermore, if the UE initiates the CLTM execution condition evaluation at an inappropriate time, it can also lead to unnecessary evaluations and measurements.

[0264] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0265] Step S2101: The network device sends the first information to the terminal.

[0266] In some embodiments, the first information is used to instruct the evaluation of the execution conditions for initiating and / or stopping the first mobility operation.

[0267] In some embodiments, the first information is used by the terminal to assess whether the execution conditions for initiating and / or stopping the first mobility operation need to be evaluated. Optionally, the first information is used to indicate start / stop conditions, which are used by the terminal to determine the execution conditions for initiating and / or stopping the first mobility operation.

[0268] Understandably, after evaluating the execution conditions for initiating the first mobility operation, the terminal can begin to determine whether the corresponding execution conditions are met, and execute the corresponding mobility operation when a certain execution condition is met. For example, the execution conditions for the first mobility operation may include a measurement event corresponding to a cell-level measurement result based on L3 measurement. When the terminal determines that the event has been triggered, it can execute the corresponding mobility operation, such as cell handover.

[0269] In some embodiments, the first information is associated with a second mobility operation command. Optionally, the second mobility operation command is used to trigger a second mobility operation. For example, the second mobility operation command may be used to instruct the terminal to perform a second mobility operation.

[0270] Optionally, the second mobility command includes at least one of a handover command, a PSCell change command, a PSCell add command, or an LTM-based cell change command.

[0271] In some embodiments, the first information may be used to trigger a second mobility operation. For example, in response to receiving a trigger command for the second mobility operation (i.e., the first information), the terminal triggers the second mobility operation and further determines an evaluation of the execution conditions for initiating and / or stopping the first mobility operation.

[0272] In some embodiments, the second mobility operation command implicitly indicates an evaluation of the conditions for the terminal to initiate and / or cease the execution of the first mobility operation.

[0273] In some embodiments, the second mobility operation command includes first information. For example, in response to receiving the second mobility operation command, the terminal initiates and / or stops the evaluation of the execution conditions for the first mobility operation based on the content of the first information included in the second mobility operation command.

[0274] In some embodiments, the number of execution conditions for the first mobility operation may be one or more.

[0275] In some embodiments, the first information includes at least one of the following: a configuration identifier corresponding to a first mobility operation to be started and / or stopped; a start / stop instruction corresponding to each configuration identifier; a threshold value; a hysteresis value; a trigger time, etc.

[0276] Optionally, the first information may be a configuration identifier used by default to indicate the first mobility operation to be stopped, or the first information may be a configuration identifier used by default to indicate the first mobility operation to be started. For example, the first information may include one or more configuration identifiers. After receiving the first information, the terminal can stop or start the evaluation of the execution conditions of the first mobility operation corresponding to one or more configuration identifiers indicated by the first information.

[0277] Optionally, the first information may indicate configuration identifiers corresponding to one or more first mobility operations to be started and one or more first mobility operations to be stopped. For example, the first information may include multiple configuration identifiers and start / stop instructions corresponding to each configuration identifier, wherein when the start / stop instruction corresponding to a certain configuration identifier is 0, the terminal may stop the evaluation of the execution conditions of the first mobility operation corresponding to that configuration identifier, and when the start / stop instruction corresponding to a certain configuration identifier is 1, the terminal may start the evaluation of the execution conditions of the first mobility operation corresponding to that configuration identifier.

[0278] Optionally, the first information may include only one or more of the threshold value, hysteresis value, and trigger time. The terminal can determine the corresponding start / stop conditions based on the information indicated by the first information, and determine whether the corresponding conditions are met to determine the evaluation of the execution conditions for starting and / or stopping the first mobility operation.

[0279] In some embodiments, the communication architecture may employ a dual-connectivity architecture, and the network devices may include an MCG and an SCG, wherein the MCG includes a PCell and the SCG includes a PSCell. Optionally, the first information may be configured by the MCG or the PCell, or it may be configured by the PSCell. Optionally, the terminal may initiate and / or halt the evaluation of the execution conditions for the corresponding first mobility event based on which device is configured with the first information.

[0280] In some embodiments, the first information may be any one of RRC, MAC CE, or DCI, or may be carried by any one of RRC, MAC CE, or DCI.

[0281] In some embodiments, the first information may also be referred to as "start / stop instruction information", "condition instruction information", "network instruction information", etc., and the names are not limited in the embodiments disclosed herein.

[0282] In some embodiments, the terminal receives first information. Optionally, after receiving the first information, the terminal evaluates the conditions for initiating and / or terminating the execution of the first mobility operation based on the first information.

[0283] In some embodiments, step S2101 is optional, and the terminal does not expect to receive the first information sent by the network device. Optionally, the terminal may initiate and / or halt the evaluation of the execution conditions for the first mobility operation based on the second mobility operation.

[0284] In step S2102, the terminal initiates and / or stops the evaluation of the execution conditions for the first mobility operation based on the first information and / or the second mobility operation.

[0285] In some embodiments, the first mobility operation includes at least one of the following: CHO; CPA; CPC; first LTM.

[0286] For example, a first mobility operation may include all of the above. The terminal may control the initiation and / or cessation of the evaluation of the execution conditions for each first mobility operation based on the first information and / or the second mobility operation. For instance, the terminal may control the initiation of the evaluation of the execution conditions for CHO and CPA, and stop the evaluation of the execution conditions for CPC and the first LTM; or, the terminal may initiate the evaluation of the execution conditions for all first mobility operations, or stop the evaluation of the execution conditions for all first mobility operations.

[0287] In some embodiments, the second mobility operation includes at least one of the following: cell handover; PSCell change; PSCell addition; LTM for primary cell group (MCG); LTM for serving cell group; LTM for secondary cell group (SCG); CHO; CPA; CPC; first LTM.

[0288] The second mobility operation can be the same as or different from the first mobility operation. For example, the second mobility operation can be a CHO, and the first mobility operation can also be a CHO. When the terminal determines that a CHO is triggered, it can further determine whether the evaluation of the conditions for starting or stopping the execution of the CHO is necessary.

[0289] In some embodiments, the first LTM is a condition-triggered L1 / L2-triggered mobility CLTM, and the CLTM includes at least one of the following: a CLTM for an MCG; a CLTM for a serving cell group; a CLTM for an SCG; and a CLTM for both an MCG and an SCG.

[0290] It is worth noting that when the terminal does not support DC, or the UE is not configured with DC, mobility operations for SCG cannot be configured, and MCG can also be referred to as the serving cell group, and PCell can be referred to as the serving cell or serving primary cell. That is, when the terminal does not support DC, or the UE is not configured with DC, the LTM for MCG can be replaced with the LTM for the serving cell group, and the CLTM for MCG can be replaced with the CLTM for the serving cell. In this case, the first mobility operation may not include the LTM and CLTM for SCG.

[0291] In some embodiments, the first mobility operation supports subsequent mobility. For example, the first mobility operation may include a Subsequent CHO, a Subsequent CPA, a Subsequent CPC, etc.

[0292] In some embodiments, the evaluation of the conditions for initiating and / or terminating the execution of the first mobility operation based on the first information and / or the second mobility operation includes at least one of the following:

[0293] The current serving cell is identified as a candidate cell for the first mobility operation, and the evaluation of the conditions for executing the first mobility operation is stopped.

[0294] An assessment of the conditions under which the second mobility operation is to be executed and the first mobility operation is to be stopped;

[0295] Once the target cell corresponding to the successful access to the second mobility operation is determined, the evaluation of the execution conditions for the first mobility operation is initiated.

[0296] Based on the instructions of the first information, the evaluation of the execution conditions for initiating and / or stopping the first mobility operation is carried out.

[0297] An assessment of the conditions for initiating and / or stopping the first mobility operation, based on the start / stop conditions indicated by the first information.

[0298] The current serving cell is the candidate cell corresponding to the first mobility operation, which may be caused by the change of the serving cell of the terminal after the terminal completes the second mobility operation.

[0299] Optionally, the evaluation of the execution conditions for the first mobility operation can be initiated and / or halted according to the second mobility operation. Specifically, this can refer to determining the initiation and / or halting of the evaluation of the execution conditions for the first mobility operation based on the execution status of the second mobility operation. For example, the evaluation of the execution conditions for the first mobility operation can be halted when the second mobility operation begins execution, and the evaluation of the execution conditions for the first mobility operation can be initiated when the second mobility operation completes execution and the current serving cell is not a candidate cell corresponding to the first mobility operation.

[0300] Optionally, the first information may include a configuration identifier corresponding to the first mobility operation to be started and / or stopped, and / or a start / stop instruction corresponding to each configuration identifier. According to the instruction of the first information, the optional implementation of the evaluation of the execution conditions for starting and / or stopping the first mobility operation can be found in the related part of step S2101, which will not be repeated here.

[0301] In some embodiments, determining to execute a second mobility operation includes at least one of the following: determining that a mobility command corresponding to the second mobility operation has been received; satisfying the execution conditions of the second mobility operation; determining the triggering cell of the second mobility operation; determining the cell selected by the second mobility operation; disconnecting from the source cell; and initiating a random channel access (RACH) to the target cell corresponding to the second mobility operation; wherein the mobility command includes at least one of a handover command, a PSCell change command, a PSCell add command, or an LTM-based cell change command. Optionally, the terminal may determine to execute the second mobility operation and stop evaluating the execution conditions of all first mobility operations when it determines that any one or more of the above conditions are satisfied.

[0302] The execution conditions for the second mobility operation can refer to the terminal meeting the execution conditions corresponding to one or more candidate configurations for the second mobility operation.

[0303] Optionally, the LTM-based cell change command could be, for example, MAC CE, such as “LTM Cell Switch Command MAC CE”.

[0304] It is understandable that the target cell for the second mobility operation can be the cell where the terminal will initiate a random access procedure. For example, when the terminal determines to perform the second mobility operation, it can initiate a random access procedure to the target cell and change the PCell or PSCell to the target cell after successful access. The target cell can be one of multiple candidate cells, which can be configured by the network through candidate configuration.

[0305] In some embodiments, determining successful access to the target cell corresponding to the second mobility operation includes at least one of the following: sending a Radio Resource Control (RRC) reconfiguration completion message to the target cell; sending the first uplink transmission data to the target cell; determining that the target cell has successfully received the first uplink transmission data; receiving the first downlink transmission data sent by the target cell; and determining that random access was successful. Optionally, the terminal may determine successful access to the target cell corresponding to the second mobility operation and initiate the evaluation of all execution conditions for the first mobility operation when any one or more of the above conditions are met.

[0306] In some embodiments, start / stop conditions include start conditions and / or stop conditions.

[0307] In some embodiments, the start and stop conditions may be determined based on the information included in the first information. For example, if the first information only includes a threshold value, the start condition may be "the first measurement result is less than or equal to the threshold value," and the stop condition may be "the first measurement result is greater than the threshold value." If the first information includes both a threshold value and a hysteresis value, the start condition may be "the sum of the first measurement result and the hysteresis value is less than or equal to the threshold value," and the stop condition may be "the difference between the first measurement result and the hysteresis value is greater than the threshold value," and so on.

[0308] In some embodiments, the start and stop conditions may be determined based on the information included in the first information. For example, if the first information only includes a threshold value, the start condition may be "the first measurement result is greater than or equal to the threshold value", and the stop condition may be "the first measurement result is less than the threshold value". If the first information includes both a threshold value and a hysteresis value, the start condition may be "the sum of the first measurement result and the hysteresis value is greater than or equal to the threshold value", and the stop condition may be "the difference between the first measurement result and the hysteresis value is less than the threshold value", and so on.

[0315] If the sum of the first measurement result and the hysteresis value is less than or equal to the threshold value within the trigger time, the evaluation of the execution conditions for the first mobility operation is initiated.

[0316] The evaluation of the conditions for stopping the execution of the first mobility operation is determined to be greater than or equal to the threshold value.

[0317] The evaluation of the conditions for stopping the execution of the first mobility operation is based on the determination that the difference between the first measurement result and the hysteresis value is greater than or equal to the threshold value.

[0318] If the first measurement result is greater than or equal to the threshold value within the trigger time, the evaluation of the conditions for stopping the execution of the first mobility operation is stopped.

[0326] The evaluation of the conditions for stopping the execution of the first mobility operation is determined by determining that the difference between the first measurement result and the hysteresis value is less than or equal to the threshold value.

[0327] The evaluation of the conditions for stopping the execution of the first mobility operation is determined by ensuring that the first measurement result is less than or equal to the threshold value within the trigger time.

Alternatively, the terminal may stop the evaluation of the execution conditions and the corresponding measurements, such as L1 measurements, for all candidate configurations of the first mobility operation. For example, if the execution of a certain first mobility operation is determined based on the L1 measurement result, the terminal may stop the L1 measurement simultaneously when determining to stop the evaluation of the execution conditions for the first mobility operation.

[0509] Step S5101: The UE controls the evaluation of the execution conditions of condition-triggered mobility based on the network-side configuration and / or the UE's mobility operation behavior.

[0510] It is understood that the evaluation of the execution conditions for controlling condition-triggered mobility includes initiating and / or stopping the evaluation of the execution conditions for condition-triggered mobility.

[0511] In this context, the UE's mobility can be equivalent to the second mobility operation designed in some of the above embodiments, and the condition-triggered mobility can be equivalent to the first mobility operation involved in some of the above embodiments.

[0516] It should be noted that if the UE does not support DC, or the UE is not configured with DC, the mobility operation including SCG described in this invention cannot be configured, and the MCG can also be called the serving cell group; PCell is called the serving cell or serving primary cell.

[0517] In some embodiments, the UE controls the evaluation of the execution conditions for condition-triggered mobility (first mobility operation) based on network-side configuration and / or the UE's mobility (second mobility operation) behavior, including at least one of the following:

[0518] In response to the UE performing a second mobility operation, the UE stops evaluating the execution conditions corresponding to the first mobility operation;

[0519] In response to the UE successfully accessing the target cell of the second mobility operation (the UE successfully completed the second mobility operation), the UE initiates the evaluation of the execution conditions corresponding to the first mobility operation;

[0520] In some embodiments, in response to the UE performing a second mobility operation, the UE stops evaluating the execution conditions corresponding to the first mobility operation, wherein the UE performing the second mobility operation includes any one or more of the following:

[0521] The UE receives a mobility command corresponding to the second mobility operation, such as any one or more of the following: a handover command, a PSCell change command, a PSCell add command, an LTM Cell Switch Command MAC CE command, etc.

[0524] The UE determined the triggering cell for the second mobility operation;

[0526] The UE disconnected from the source cell;

[0532] The UE receives the first downlink transmission sent by the target cell;

[0533] UE random access successful (UE successfully initiated random access on the target cell);

[0534] In some embodiments, restarting the evaluation of the execution conditions corresponding to the first mobility operation requires restarting the TTT of the event configuration corresponding to the execution conditions.

[0535] In some embodiments, the UE, based on network-side configuration information, initiates and / or stops the evaluation of the execution conditions corresponding to the UE initiating a first mobility operation, including one or more of the following:

[0536] Based on the instructions from the network side, the UE initiates and / or stops the evaluation of the execution conditions corresponding to the UE initiating the first mobility operation;

[0537] Based on the start / stop conditions configured on the network side, the UE initiates and / or stops the evaluation of the execution conditions corresponding to the UE initiating the first mobility operation;

[0538] The UE receives an instruction from the network side, which instructs the UE to initiate (or stop) the evaluation of the execution conditions corresponding to the first mobility operation.

[0539] Optionally, the indication information can be used to instruct the UE to evaluate the execution conditions of a specific configuration corresponding to the first mobility.

[0540] For example, the indication information may include a configuration identifier of the first mobility configuration and the start (or stop) status of the corresponding execution condition assessment.

[0541] For example, the indication information may include a configuration identifier of the first mobility configuration for which evaluation is initiated (or evaluation is stopped).

[0542] For example, the indication information can be indicated by RRC, MAC CE or DCI.

[0543] In some embodiments, the UE initiates and / or stops the evaluation of the execution conditions corresponding to the UE initiating a first mobility operation based on the initiation (or stop) conditions configured on the network side, including:

[0550] In some embodiments, the start condition (or stop condition) may be:

[0552] Start: The measurement result of the current beam of the serving cell is less than the threshold value; Stop: The measurement result of the current beam of the serving cell is greater than the threshold value;

[0557] In some embodiments, since hysteresis values ​​and / or trigger time information can be configured, hysteresis values ​​and / or trigger time information can be taken into account when evaluating start conditions (or stop conditions);

[0558] For example, consider the condition "Start: The measurement result of the serving cell is less than the threshold; Stop: The measurement result of the serving cell is greater than the threshold" (other conditions are similar):

[0559] Considering hysteresis, start: the measurement result of the serving cell plus the hysteresis value is less than the threshold value; stop: the measurement result of the serving cell minus the hysteresis value is greater than the threshold value.

[0560] Considering the trigger time, start: the measurement results of the serving cell are all less than the threshold value within the trigger time; stop: the measurement results of the serving cell are all greater than the threshold value within the trigger time.

[0561] Considering hysteresis and trigger time, the following conditions apply: Start: The measurement result of the serving cell plus the hysteresis value is less than the threshold value within the trigger time; Stop: The measurement result of the serving cell minus the hysteresis value is greater than the threshold value within the trigger time.

[0565] In some embodiments, when the UE performs a second mobility operation or when the UE successfully accesses the target cell of the second mobility operation, the UE deletes the stored measurement samples, wherein the measurement samples are measurement results corresponding to the source serving cell or measurement results of all cells to be tested.

[0566] In some embodiments, if the current serving cell is one of the candidate cells for a second mobility operation, the UE stops evaluating the execution conditions corresponding to the serving cell.
