Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and apparatus for mobility management of terminal devices.

Background Art

[0002] A dual connectivity (DC) terminal device can access two cell groups, namely a master cell group (MCG) and a secondary cell group (SCG) respectively. The MCG corresponds to a network-side master node (MN), and the SCG corresponds to a network-side secondary node (SN).

[0003] In the current system, a terminal device can implement condition-based mobility based on conditions set by a network device and related candidate cells. The conditions set by the network device may be events based on specific measurement results, or events based on location, or events based on time, etc. The terminal device can perform the mobility of the MCG by executing conditional handover (CHO), and can perform the mobility of the SCG by executing conditional primary secondary cell addition (CPA) or conditional primary secondary cell change (CPC).

[0004] However, such condition-based mobility is only applicable to scenarios where CHO or CPA / CPC is set individually, and does not support setting CHO and CPA / CPC simultaneously.

[0069] To facilitate understanding, we will first introduce the terminology used in this disclosure.

[0070] 1. Primary Cell (PCell) In MCG, there can be multiple cells, among which is one cell used to initiate initial access; this cell is called a PCell. As the name suggests, the PCell is the "primary" cell in MCG.

[0071] 2. Secondary Cell (SCell) In MCG, secondary cells are SCells. PCells and SCells in MCG are joined by carrier aggregation CAs, and MCG contains one or more SCells.

[0072] 3. Primary Secondary Cell (PSCell) In an SCG, the primary and secondary cells are PSCells, and an SCG contains one or more SCells.

[0073] 4. Conditional handover (CHO) A terminal device can select a target network device based on pre-configured conditions, initiate a switching process, and start random access to the target network device. The terminal device can achieve master cell group (MCG) mobility by executing a CHO (Command, Assistance, and Operation) command.

[0074] 5. Conditional Primary / Secondary Cell Addition (CPA) The terminal device can determine which PSCells can be added based on pre-configured conditions. The terminal device can enable the mobility of secondary cell groups (SCGs) by performing CPA.

[0075] 6. Conditional Primary / Secondary Cell Change (CPC) The terminal device determines accessible target PSCells based on pre-configured conditions. The terminal device can achieve SCG mobility by executing CPC.

[0076] 7. Mobility processes triggered based on conditions In the 5th Generation Mobile Communication Technology (5G) system, Terminal devices can move between cells based on "pre-configured conditions" of the network device and "pre-configured cells" corresponding to those conditions. When a terminal device meets a "pre-configured condition," such as a specific measurement event, the terminal device changes its service cell to a "pre-configured cell." Here, this "condition-based mobility process" includes Conditional Handover (CHO), Conditional PSCell Addition (CPA), and Conditional PSCell Change (CPC).

[0077] To better understand the methods for managing the mobility of terminal devices disclosed in the embodiments of this disclosure, the following will first describe the communication systems applicable to the embodiments of this disclosure.

[0078] Referring to Figure 1, Figure 1 shows the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, one network device and one terminal device. The number and configuration of devices shown in Figure 1 are merely examples and do not constitute limitations of the embodiments of the present disclosure. In actual applications, it may include two or more network devices, two or more auxiliary communication devices, and two or more terminal devices. The communication system shown in Figure 1 is an example consisting of one master node 11, one terminal device 12, and one secondary node 13.

[0079] Furthermore, the technical concepts of the embodiments described herein are applicable to a variety of communication systems. For example, they may be applied to long-term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0080] In the embodiments of this disclosure, the master node 11 and secondary node 13 are entities for transmitting and receiving signals on the network side, and may be terminal devices 12, corresponding primary nodes, and secondary nodes, respectively. For example, the master node 11 and secondary node 13 may be evolved NodeB (eNB), transmission reception point (TRP), next-generation NodeB (gNB) in an NR system, a base station in another future mobile communication system, or an access point in a wireless fidelity (WiFi) system. The embodiments of this disclosure do not limit the specific technologies and device forms used for network devices. The network devices provided by the embodiments of this disclosure may consist of a central unit (CU) and a distributed unit (DU), where the CU is also called a control unit, and by using a CU-DU structure, the protocol layer of a base station, for example, can be separated, with some functions of the protocol layer being centrally controlled by the CU, and some or all of the remaining functions of the protocol layer being distributed in the DU, with the DU being centrally controlled by the CU.

[0081] In the embodiments of this disclosure, the terminal device 12 is an entity for transmitting and receiving signals on the user side, such as a mobile phone. The terminal device may also be called a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile equipped with communication functions, a smart car, a mobile phone, a wearable device, a tablet (Pad), a personal computer equipped with wireless transmission and reception functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology and specific device form used for the terminal device.

[0082] The communication systems described in the embodiments of this disclosure are provided to more clearly illustrate the technical solutions of the embodiments of this disclosure and do not limit the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will see, with the evolution of system architectures and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are similarly applicable to similar technical problems.

[0083] To support the simultaneous configuration of CHO and CPA / CPC, it is necessary to study the trigger method when CHO and CPA / CPC are configured simultaneously. In this disclosure, a network device can transmit information for condition-based mobility to a terminal device, and the terminal device can then perform selective condition-based mobility based on the satisfaction status of the conditions for performing condition-based mobility, thereby improving the reliability and accuracy of mobility management.

[0084] In this disclosure, the method for managing the mobility of a terminal device provided by any one embodiment can be performed individually, or in combination with possible implementations in other embodiments, or in combination with any technical proposal of the related technology.

[0085] The following describes in detail, in conjunction with the drawings, the mobility management method and apparatus for terminal devices provided in this disclosure.

[0086] Referring to Figure 2, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 2, the method may include, but is not limited to, the following steps: Step 201, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0087] Information for condition-based mobility may include condition reset information.

[0088] Optionally, information for condition-based mobility may include at least one of the following: the conditions for performing condition-based mobility, the setting information for the target cell, the relationship between the CHO and CPA, and the relationship between the CHO and CPC.

[0089] Selectively, the CHO setting can be associated with the CPC setting, or the CHO setting can be associated with the CPA setting. That is, a terminal device can receive a jointly configured CHO and CPC by a network device, or a terminal device can receive a jointly configured CHO and CPA by a network device. The joint configuration can indicate, implicitly or explicitly, in the information transmitted by the network device, that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0090] For example, the relationship between the CHO settings and the CPC (or CPA) settings can be indicated by including both settings in the same configuration message.

[0091] Alternatively, the CHO setting and the CPC setting can be associated with the same setting identifier, thereby indicating that the CHO setting is associated with the CPC setting; and accordingly, the CHO setting and the CPA setting can be associated with the same setting identifier, thereby indicating that the CHO setting is associated with the CPA setting. The setting identifier may be any information that uniquely determines a joint setting, such as a condition reset number, but this disclosure is not limited to such information.

[0092] Alternatively, the settings of the CHO can be associated with the settings of the CPC (or CPA) by specifying the settings of the associated CPC or CPA in the settings of the CHO.

[0093] Alternatively, by indicating the CHO setting associated with the CPC setting or the CPA setting, it is possible to indicate that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0094] Alternatively, it may be indicated that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting, through relevant information.

[0095] For example, it is possible to indicate through information elements (IE) that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting, or it is also possible to indicate through related fields that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0096] Step 202: Execute the condition-based mobility based on the satisfaction status of the conditions for executing the condition-based mobility.

[0097] In this disclosure, a terminal device can evaluate the conditions for performing condition-based mobility, and if it is determined that the terminal device satisfies the conditions for performing any condition-based mobility, it can perform that condition-based mobility.

[0098] If it is determined that the terminal device meets the conditions for performing CHO, MCG mobility may be performed, or if it is determined that the terminal device meets the conditions for performing CPA, SCG mobility may be performed, and this disclosure is not limited thereto.

[0099] This disclosure allows a terminal device to perform condition-based mobility after receiving information for condition-based mobility transmitted by a network device, based on the satisfaction status of the conditions for performing condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively performing the corresponding condition-based mobility based on the satisfaction status of the conditions for performing condition-based mobility.

[0100] Referring to Figure 3, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 3, the method may include, but is not limited to, the following steps. Step 301, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0101] In this disclosure, the specific implementation process of step 401 can be found in the detailed description of any embodiment of this disclosure, and a detailed description is omitted here.

[0102] Step 302: In response to the conditions for executing CHO being met, the timer is started.

[0103] Step 303, in response to the timer being operational and the conditions for executing CPC or CPA being met, the CHO and CPC or CPA are executed.

[0104] Selectively, if the timer is running and the execution conditions for the terminal device CPC or CPA are met, the terminal device can execute the CHO and CPC (or CPA), regardless of whether the execution conditions for the CHO are met at that time. This means it can apply the corresponding CHO and CPA (or CPA) settings, for example, by performing a radio resource control (RRC) reconfiguration.

[0105] Selectively, if the timer is running and the execution conditions for the terminal device CPC are met, and the execution conditions for CHO are still met at that time, i.e., if the terminal device simultaneously meets the execution conditions for both CHO and CPC, then CHO and CPC can be executed.

[0106] Selectively, if the timer is running and the execution conditions for the terminal device CPA are met, and the execution conditions for CHO are still met at that time, i.e., if the terminal device simultaneously meets the execution conditions for both CHO and CPA, then CHO and CPA can be executed.

[0107] If the timer is running and the conditions for the terminal device CPC or CPA execution are met, the timer can be stopped as an option.

[0108] This disclosure describes a step in which, after a terminal device receives information for condition-based mobility transmitted by a network device, if the execution conditions for CHO are met, a timer is started, and if the timer is running and the execution conditions for CPC or CPA are met, CHO and CPC are executed, or CHO and CPA are executed. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for condition-based mobility.

[0109] Referring to Figure 4, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 4, the method may include, but is not limited to, the following steps. Step 401, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0111] In this disclosure, step 4 01-The specific implementation process of step 402 can be found in the detailed description of any embodiment of this disclosure, and is therefore omitted here.

[0112] Step 403: In response to the timer expiring, execute CHO.

[0113] In this disclosure, when the timer expires, the terminal device can apply the settings corresponding to the CHO and execute the CHO, for example, by applying the RRC reconfiguration associated with the CHO.

[0114] If, as an option, the timer expires but the terminal device still does not meet the conditions for executing CPC or CPA, the terminal device can apply the settings corresponding to CHO and execute CHO, for example, by applying the RRC reconfiguration associated with CHO.

[0115] Optionally, when the timer expires, the terminal device can delete information for condition-based mobility.

[0116] Selectively, a terminal device deleting information for condition-based mobility includes deleting one or more of the following: the conditions for performing condition-based mobility, the configuration information of the target cell, the relationship between the CHO and the CPA, and the relationship between the CHO and the CPC.

[0117] If the timer expires, the terminal device may optionally delete the CHO setting and / or the CPC (or CPA) setting associated with this CHO.

[0118] Optionally, when the timer expires, the terminal device can delete all or some of the CHO settings. Optionally, when the timer expires, the terminal device can delete all or some of the CPC (or CPA) settings. Optionally, when the timer expires, the terminal device can execute the CHO if it meets the execution conditions.

[0119] Selectively, if the timer expires and the terminal device meets the execution conditions for CHO, CHO can be executed even if the execution conditions for CPC are not met.

[0120] In this disclosure, after a terminal device receives information for condition-based mobility transmitted by a network device, if the execution conditions for a CHO are met, a timer is started, and when the timer expires, the CHO is executed. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for condition-based mobility.

[0121] Referring to Figure 5, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 5, the method may include, but is not limited to, the following steps. Step 501, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0122] Step 502: In response to the conditions for executing CHO being met, the timer is started.

[0123] In this disclosure, the specific implementation processes of steps 501-502 can be found in the detailed descriptions of any embodiment of this disclosure, and are therefore omitted here.

[0124] Step 503: In response to the expiration of a pre-set timer, restart the process to determine whether the conditions for performing condition-based mobility have been met.

[0125] Selectively, in response to the expiration of a pre-set timer, it is determined whether or not the execution conditions for CHO and CPC are met.

[0126] Selectively, in response to the expiration of a pre-set timer, it is determined whether or not the execution conditions for CHO and CPA are met.

[0127] Selectively, in response to the expiration of a pre-set timer, it is determined whether the execution conditions for CHO and CPC are met.

[0128] Selectively, in response to the expiration of a pre-set timer, it is determined whether the execution conditions for CHO and CPA have been met.

[0129] In this disclosure, if the timer expires, the terminal device can re-determine the satisfaction status of the conditions for performing condition-based mobility.

[0130] If the timer expires, the terminal device can optionally re-determine the satisfaction status of the execution conditions for CHO and CPC.

[0131] If the timer expires, the terminal device can optionally re-determine the satisfaction status of the execution conditions for CHO and CPA.

[0132] If the timer expires, the terminal device can optionally re-determine the satisfaction status of the CHO execution conditions and the CPC execution conditions.

[0133] Optionally, if the timer expires, the terminal device can re-determine the satisfaction status of the CHO execution conditions and CPA execution conditions. In this disclosure, after the terminal device receives information for condition-based mobility transmitted by the network device, it starts the timer if the CHO execution conditions are met, and if the timer expires, it determines whether the restart CHO and CPC execution conditions are met. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for that condition-based mobility.

[0134] Referring to Figure 6a, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 6a, the method may include, but is not limited to, the following steps: Step 601, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0135] In this disclosure, the specific implementation process of step 601 can be found in the detailed description of any embodiment of this disclosure, and a detailed description is omitted here.

[0136] Step 602: In response to the conditions for executing the CHO and the CPC being met, execute the CHO and CPC.

[0137] In this disclosure, a terminal device can evaluate the execution conditions for CHO and CPC, respectively, to determine whether the terminal device satisfies the execution conditions for CHO and CPC. If the execution conditions for CHO and CPC are met, the terminal device can execute CHO and CPC.

[0138] Optionally, the terminal device may also execute CHO and CPA if it determines that it has met the conditions for executing CHO and CPA.

[0139] In other words, the terminal device can evaluate the execution conditions for CHO and CPA, respectively, and determine whether the terminal device satisfies the execution conditions for CHO and CPA. If the execution conditions for CHO and CPA are met, the terminal device can execute CHO and CPA.

[0140] For example, if the execution condition for CHO is that the first measured value is greater than the first threshold, and the execution condition for CPC is that the second measured value is greater than the second threshold, the terminal device can evaluate whether the first measured value is greater than the first threshold and whether the second measured value is greater than the second threshold. If it is determined that the first measured value is greater than the first threshold and the second measured value is greater than the second threshold, then CHO and CPC can be executed.

[0141] The first and second measurements may be, as selectable, measurements of the same quantity or measurements of different quantities, and this disclosure is not limited thereto.

[0142] This disclosure allows a terminal device to execute a CHO and CPC (or CPA) after receiving information for condition-based mobility transmitted by a network device, provided that the execution conditions for the CHO and CPC (or CPA) are met. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for condition-based mobility.

[0143] Referring to Figure 6b, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 6b, the method may include, but is not limited to, the following steps: Step 601b, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility includes setting the condition switching (CHO) and / or conditions. PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0144] In this disclosure, the specific implementation process of step 601b can be found in the detailed description of any embodiment of this disclosure, and a detailed description is omitted here.

[0145] Step 602b: In response to the conditions for executing the CHO and CPC being met, the CHO and CPC are executed.

[0146] In this disclosure, a terminal device can evaluate the execution conditions for CHO and CPC to determine whether or not the execution conditions for terminal device CHO and CPC are met, and if the execution conditions for CHO and CPC are met, it can execute CHO and CPC. The execution conditions for CHO and CPC are the same.

[0147] Selectable, the execution conditions for CHO and CPC are identical. For example, the execution conditions for both CHO and CPC are that the measured value is greater than the third threshold, and the terminal device will execute CHO and CPC when it determines that the measured value is greater than the first threshold.

[0148] Optionally, the terminal device may also perform CHO and CPA if it is determined that the conditions for performing CHO and CPA are met.

[0149] In other words, the terminal device can evaluate the execution conditions for CHO and CPA and determine whether the terminal device meets the execution conditions for CHO and CPA. If the execution conditions for CHO and CPA are met, it can execute CHO and CPA. The execution conditions for CHO and CPA are the same.

[0150] Selectively, the execution conditions for CHO and CPA are the same. For example, the execution conditions for both CHO and CPA are that the measured value is greater than the fourth threshold, so the terminal device can execute CHO and CPA when it determines that the measured value is greater than the fourth threshold.

[0151] The third and fourth thresholds mentioned above are for illustrative purposes only and are not limited to their magnitude in this disclosure.

[0152] This disclosure allows a terminal device to execute a CHO and CPC (or CPA) after receiving information for condition-based mobility transmitted by a network device, provided that the conditions for executing the CHO and CPC (or CPA) are met. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the conditions for executing the condition-based mobility.

[0153] Referring to Figure 7, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device.

[0157] Step 703: After it is determined that the conditions for executing the CHO are met, it is determined whether the conditions for executing the CPA or CPC are met.

[0158] In this disclosure, after the terminal device satisfies the execution conditions of the CHO, the execution conditions of the CPC or CPA can be evaluated to determine the level of satisfaction of the execution conditions of the CPC or CPA.

[0159] Step 704: Execute condition-based mobility based on the satisfaction status of the conditions for executing condition-based mobility.

[0160] In this disclosure, the specific implementation process of step 704 can be found in the detailed description of any embodiment of this disclosure, and a detailed description is omitted here.

[0161] This disclosure allows a terminal device to receive information for condition-based mobility transmitted by a network device, determine whether the execution conditions for the Chief Action Handout (CHO) are met, and then, after determining that the execution conditions for the CHO are met, determine whether the execution conditions for the CPA or CPC are met. Subsequently, based on the satisfaction status of the execution conditions for the condition-based mobility, the terminal device can execute the condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for the condition-based mobility.

[0162] Referring to Figure 8, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 8, the method may include, but is not limited to, the following steps.

[0172] Step 803: Execute condition-based mobility based on the satisfaction status of the conditions for executing condition-based mobility.

[0173] This disclosure allows a terminal device to receive information for condition-based mobility transmitted by a network device, determine whether the execution conditions for CHO and CPA are met, and then execute condition-based mobility based on the satisfaction status of the execution conditions for condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the execution conditions for condition-based mobility.

[0174] Referring to Figure 9, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by the terminal device. As shown in Figure 9, the method may include, but is not limited to, the following steps: Step 901, receive information for condition-based mobility transmitted by the network device, and the information for condition-based mobility sets the Condition Switching (CHO) and / or conditions PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0175] Step 902: Execute condition-based mobility based on the satisfaction status of the conditions for executing condition-based mobility.

[0176] In this disclosure, the specific implementation processes of steps 901-902 can be found in the detailed descriptions of any embodiment of this disclosure, and are therefore omitted here.

[0177] Step 903, Instruction information is sent to a network device, which is used to indicate any one of the following: the result of the CHO and / or CPA execution, or the result of the CHO and / or CPC execution.

[0178] Furthermore, the execution results may further include the type of reset performed by the terminal device, such as MCG reset and / or SCG reset. MCG reset may include CHO, and SCG reset may include CPA / CPC, etc.

[0179] In this disclosure, after a terminal device has completed the execution of CHO and CPA (or CPA), the results of the execution of CHO and CPA (or CPA) can be included in a Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information, thereby enabling a network device to decide whether the terminal device should perform CHO and CPA (or CPA) after receiving the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information.

[0180] The RRC reconfiguration complete message may include response information corresponding to performing MCG mobility, indicating that the UE is performing CHO.

[0181] Alternatively, the RRC reconfiguration complete message may include response information corresponding to performing SCG mobility, indicating that the UE will perform CPA or CPC.

[0182] Alternatively, the RRC reset completion message may include response information corresponding to performing MCG mobility and response information corresponding to performing SCG mobility, indicating that the UE will perform CHO and CPA or CPC. The response information corresponding to performing MCG mobility and the response information corresponding to performing SCG mobility may be the same or different, and may be identical or different information, and this disclosure is not limited thereto. The RRC reconfiguration complete message may contain response information corresponding to performing SCG mobility, and this message may be forwarded from the primary node to the secondary node, and may include an RRC reconfiguration complete message to be forwarded to the secondary node.

[0183] Alternatively, after a terminal device completes the execution of a CHO, the result of the CHO can be included in the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information, allowing the network device to decide whether the terminal device should perform a CHO after receiving the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information.

[0184] The RRC reconfiguration complete message may include response information corresponding to performing MCG mobility, indicating that the UE is performing CHO.

[0185] Optionally, the RRC reconfiguration complete message may not include response information corresponding to performing SCG mobility, indicating that the UE will not perform CPA or CPC.

[0186] This disclosure describes how a terminal device, after receiving information for condition-based mobility transmitted by a network device, can perform condition-based mobility based on the satisfaction of the conditions for performing condition-based mobility, and then transmit instruction information to the network device to inform the network device that the terminal is performing the corresponding condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively performing the corresponding condition-based mobility based on the satisfaction of the conditions for performing condition-based mobility.

[0187] Referring to Figure 10, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by a network device. As shown in Figure 10, the method may include, but is not limited to, the following steps.

PSCell Change (CPC) settings, CHO settings and / or conditions PSCell Includes any one of the following settings: Additional (CPA) settings.

[0188] Information for condition-based mobility may include condition reset information.

[0189] Optionally, information for condition-based mobility may include at least one of the following: the conditions for performing condition-based mobility, the setting information for the target cell, the relationship between the CHO and CPA, and the relationship between the CHO and CPC.

[0190] Selectively, the CHO setting can be associated with the CPC setting, or the CHO setting can be associated with the CPA setting. That is, a network device can co-configure the CHO and CPC and send the co-configuration of the CHO and CPC to a terminal device, or a network device can co-configure the CHO and CPA and send the co-configuration of the CHO and CPA to a terminal device. The co-configuration can indicate, implicitly or explicitly, in the transmitted information that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0191] For example, the relationship between the CHO settings and the CPC (or CPA) settings can be indicated by including both settings in the same configuration message.

[0192] Alternatively, the CHO setting and the CPC setting can be associated with the same setting identifier, thereby indicating that the CHO setting is associated with the CPC setting; and accordingly, the CHO setting and the CPA setting can be associated with the same setting identifier, thereby indicating that the CHO setting is associated with the CPA setting. The setting identifier may be any information that uniquely determines a joint setting, such as a condition reset number, but this disclosure is not limited to such information.

[0193] Alternatively, the settings of the CHO can be associated with the settings of the CPC (or CPA) by specifying the settings of the associated CPC or CPA in the settings of the CHO.

[0194] Alternatively, by indicating the CHO setting associated with the CPC setting or the CPA setting, it is possible to indicate that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0195] Alternatively, it may be indicated that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting, through relevant information.

[0196] For example, it is possible to indicate through information elements (IE) that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting, or it is also possible to indicate through related fields that the CHO setting is associated with the CPC setting, or that the CHO setting is associated with the CPA setting.

[0197] This disclosure allows a network device to transmit information for condition-based mobility to a terminal device, and then the terminal device can perform condition-based mobility based on the satisfaction of the conditions for performing condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively performing the corresponding condition-based mobility based on the satisfaction of the conditions for performing condition-based mobility.

[0198] Referring to Figure 11, which is a flowchart of a mobility management method for a terminal device provided by an embodiment of the present disclosure, the method is performed by a network device.

[0201] Furthermore, the execution results may further include the type of reset performed by the terminal device, such as MCG reset and / or SCG reset. MCG reset may include CHO, and SCG reset may include CPA / CPC, etc.

[0202] In this disclosure, after a terminal device has completed the execution of CHO and CPA (or CPA), the results of the execution of CHO and CPA (or CPA) can be included in a Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information, thereby enabling a network device to decide whether the terminal device should perform CHO and CPA (or CPA) after receiving the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information.

[0203] The RRC reconfiguration complete message may include response information corresponding to performing MCG mobility, indicating that the UE is performing CHO.

[0204] Alternatively, the RRC reconfiguration complete message may include response information corresponding to performing SCG mobility, indicating that the UE will perform CPA or CPC.

[0205] Alternatively, the RRC reset completion message may include response information corresponding to performing MCG mobility and response information corresponding to performing SCG mobility, indicating that the UE will perform CHO and CPA or CPC. The response information corresponding to performing MCG mobility and SCG mobility may be the same or different, and may be identical or different information, and this disclosure is not limited thereto. The RRC reconfiguration complete message may contain response information corresponding to performing SCG mobility, and this message may be forwarded from the primary node to the secondary node, and may include an RRC reconfiguration complete message to be forwarded to the secondary node.

[0206] Alternatively, after a terminal device completes the execution of a CHO, the result of the CHO can be included in the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information, allowing the network device to decide whether the terminal device should perform a CHO after receiving the Radio Resource Control (RRC) reconfiguration completion message or terminal device auxiliary information.

[0207] The RRC reconfiguration complete message may include response information corresponding to performing MCG mobility, indicating that the UE is performing CHO.

[0208] Optionally, the RRC reconfiguration complete message may not include response information corresponding to performing SCG mobility, indicating that the UE will not perform CPA or CPC.

[0209] In this disclosure, a network device transmits information for condition-based mobility to a terminal device, and then, based on the satisfaction status of the terminal device's condition-based mobility execution conditions, can execute condition-based mobility. The network device also transmits instruction information to inform the network device that the terminal is executing the corresponding condition-based mobility. This improves the reliability, accuracy, or robustness of mobility management by selectively executing the corresponding condition-based mobility based on the satisfaction status of the condition-based mobility execution conditions.
