Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a configuration method and apparatus for mobility management. Background Technology

[0002] In 5G systems, terminal devices can perform mobility management based on pre-configured network conditions and corresponding pre-configured cells. When a terminal device meets the pre-configured conditions, such as a specific measurement event, it can change its serving cell to the pre-configured cell. This condition-triggered mobility process typically includes Conditional Handover (CHO), Conditional Primary / Secondary Cell Addition (CPA), and Conditional Primary / Secondary Cell Change (CPC).

[0003] In the current system, it is not possible to configure CHO and CPA (or CPC) for terminal devices that support DC at the same time.

[0039] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0040] 1. Dual connectivity (DC) terminal equipment

[0041] DC terminal equipment can access two cell groups, namely the master cell group (MCG) and the secondary cell group (SCG). MCG corresponds to the network-side master node (MN), and SCG corresponds to the network-side secondary node (SN).

[0042] 2. Primary Cell (PCell)

[0043] Under an MCG, there may be many cells, one of which is used to initiate initial access; this cell is called the PCell. As the name suggests, the PCell is the most "primary" cell in the MCG.

[0044] 3. Secondary Cell (SCell)

[0045] The secondary cells in an MCG are SCells. PCells and SCells under an MCG are combined together through carrier aggregation (CA). An MCG contains one or more SCells.

[0046] 4. Primary Secondary Cell (PSCell)

[0047] The primary and secondary cells in an SCG are PSCells, and an SCG contains one or more SCells.

[0048] 5. Conditional Handover (CHO)

[0049] Terminal devices can select a target network device based on pre-configured conditions and initiate a handover process to randomly access the target network device. Terminal devices can achieve MCG mobility by executing CHOs.

[0050] 6. Conditional PSCell Addition (CPA)

[0051] The terminal device can determine the PSCells that can be added based on pre-configured conditions. The terminal device can achieve SCG mobility by executing CPA.

[0052] 7. Conditional PSCell Change (CPC).

[0053] The terminal device can determine the modifiable PSCell based on pre-configured conditions. The terminal device can achieve SCG mobility by executing CPC.

[0054] To better understand the mobility management configuration method disclosed in this disclosure, the communication system to which this disclosure applies will be described first.

[0055] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of the devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, it may include two or more network devices, two or more auxiliary communication devices, and two or more terminal devices. Figure 1 The communication system shown is an example including a master node 11, a terminal device 12, and a slave node 13.

[0056] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0057] In this embodiment, the primary node 11 and secondary node 13 are network-side entities used for transmitting or receiving signals. They can be the primary node and secondary node corresponding to the terminal device 12, respectively. For example, the primary node 11 and secondary node 13 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. This embodiment does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of the network device, such as a base station, can be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0058] In this disclosure, the terminal device 12 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, 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, and so on. This disclosure does not limit the specific technology or device form used in the terminal device.

[0059] 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 provided 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 provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0060] In this disclosure, in order to simultaneously improve the reliability of the MCG mobility process and the SCG mobility process of a dual-connection terminal device, the terminal device can be provided with mobility management configuration for the MCG and / or mobility management configuration for the SCG. This allows the terminal device to trigger CHO and / or CPA, or trigger CHO and / or CPC, depending on the scenario, thereby improving the reliability of the MCG mobility process and the SCG mobility process.

[0061] It should be noted that, in this disclosure, any embodiment of the method for processing conditional reconfiguration information can be executed alone, or it can be executed together with possible implementation methods in other embodiments, or it can be executed together with any technical solution in the related technologies.

[0062] Please see Figure 2 , Figure 2 This is a flowchart illustrating a mobility management configuration method provided in an embodiment of this disclosure, which is executed by a network device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0063] Step 201: Send the configuration information of condition-triggered cell management and the type of condition-triggered cell management to the terminal device.

[0064] 1. Optionally, the configuration information for condition-triggered cell management may include at least one of the following: mobility management triggering event, target cell configuration, and the association between mobility management triggering event and target cell configuration.

[0065] 2. The mobility management trigger event can be any trigger event that meets a specific measurement result. For example, the Reference Signal Received Power (RSRP) value of the target cell exceeds a threshold value.

[0066] 3. Optionally, the mobility management trigger event may include at least one of the following: a trigger event for MCG mobility management; a trigger event for SCG mobility management; a trigger event for simultaneous MCG and SCG mobility management; a trigger event for both MCG and SCG mobility management; a trigger event for both SCG and MCG mobility management; and a trigger event for both MCG and SCG mobility management.

[0067] 4. Among them, the triggering events used for simultaneous MCG and SCG mobility management include any one of the following: triggering events for evaluating MCG mobility; triggering events for evaluating SCG mobility; multiple triggering events for evaluating MCG mobility and triggering events for evaluating SCG mobility.

[0068] 5. That is, the triggering event may be used only to evaluate MCG mobility assessment, without evaluating the measurement results of SCG cells; or it may be used only to evaluate SCG mobility assessment, without evaluating the measurement results of MCG cells; or it may include multiple events, among which there are triggering events for evaluating MCG mobility and triggering events for evaluating SCG mobility.

[0069] 6. Among them, the mobility management triggering events associated with the target cell configuration can be one or more.

[0070] 7. Optionally, if the triggering events used for simultaneous MCG and SCG mobility management include multiple triggering events for evaluating MCG mobility and multiple triggering events for evaluating SCG mobility, the terminal device may apply the target cell configuration when all multiple triggering events are satisfied, or it may apply the target cell configuration when any one of the multiple triggering events is satisfied, etc. This disclosure does not limit this.

[0071] 8. Additionally, trigger events used for MCG mobility management and simultaneous MCG and SCG mobility management refer to events that can be used to trigger MCG mobility management, or events that can be used to determine the triggering of MCGs in simultaneous MCG and SCG mobility management. For example, if the trigger event for MCG switching is A1, and the trigger event for SCG change or addition is A2, then when both the trigger event A1 for MCG switching and the trigger event A2 for SCG change or addition are satisfied, the A1+A2 event can be used to trigger simultaneous MCG mobility management and SCG mobility management.

[0072] 9. Correspondingly, the triggering event used for SCG mobility management and simultaneous MCG and SCG mobility management refers to an event that can be used to trigger SCG mobility management, or it can be used to trigger SCG in simultaneous MCG and SCG mobility management. For example, if the triggering event for SCG change or addition is A3, and the triggering event for MCG switching is A4, then when both the triggering event A3 for SCG change or addition and the triggering event A4 for MCG switching are satisfied, then the A3+A4 event can be used to trigger simultaneous MCG mobility management and SCG mobility management.

[0073] 10. Additionally, trigger events used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management refer to events that can trigger MCG mobility management, SCG mobility management, or the SCG triggering determination within simultaneous MCG and SCG mobility management. For example, trigger event A5 can be used to trigger SCG change or addition, or trigger MCG switching; trigger event A1 can be used to trigger MCG switching; and trigger event A3 can be used to trigger SCG change or addition. When trigger events A5 and A1 are both satisfied, they can be used to trigger simultaneous MCG and SCG mobility management. Conversely, when trigger events A5 and A3 are both satisfied, the A3+A5 event can be used to trigger simultaneous MCG and SCG mobility management.

[0074] 11. Optionally, the target cell configuration includes at least one of the following: target cell configuration information for MCG mobility management; target cell configuration information for SCG mobility management; target cell configuration information for simultaneous MCG and SCG mobility management; target cell configuration information for both MCG and SCG mobility management; target cell configuration information for both SCG and MCG mobility management; and target cell configuration information for both MCG and SCG mobility management.

[0075] 12. Among them, the target cell configuration information used for simultaneous MCG and SCG mobility management refers to the target cell configuration information used for simultaneous MCG and SCG mobility management; the target cell configuration information used for both MCG mobility management and simultaneous MCG and SCG mobility management refers to the target cell configuration information that can be used for both MCG mobility management and simultaneous MCG and SCG mobility management. Correspondingly, the target cell configuration information used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management refers to the target cell configuration information that can be used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management.

[0076] For example, if the configuration information for condition-triggered cell management includes a triggering event for evaluating MCG mobility and target cell configuration information for MCG mobility management, then the terminal device can execute the corresponding target cell configuration information for MCG mobility management after the triggering event is met.

[0077] Alternatively, if the configuration information for condition-triggered cell management includes: target cell configuration information for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management, then the terminal device can execute the target cell configuration information when it determines that the execution conditions for CHO are met, or it can execute the target cell configuration information when it determines that the execution conditions for CHO and CPC (or CPA) are met, or it can execute the target cell configuration information when it determines that the execution conditions for CPA are met, and so on.

[0078] Optionally, the network device can configure target cell configuration information for MCG mobility management and target cell configuration information for SCG mobility management for the terminal device in a single message. For example, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are included in a Radio Resource Control (RRCReconfiguration) message that is used to configure both MCG and SCG.

[0079] Alternatively, different messages can be used to configure the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management separately for the terminal device. For example, the target cell configuration information for MCG mobility management can be included in the Radio Resource Control (RRCReconfiguration) message used to configure MCG, while the target cell configuration information for SCG mobility management can be included in the RRCReconfiguration message used to configure SCG.

[0080] That is, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are contained in different messages; or, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are contained in the same message.

[0081] Optionally, the target cell configuration may also include mobility management trigger events, or condition-triggered cell management configuration information.

[0082] For example, the RRCReconfiguration message configuring target cell configuration information for a terminal device may include mobility management trigger event configuration. This mobility management trigger event configuration may be used only for SCG mobility management trigger events; or it may be used only for MCG mobility management trigger events; or it may be used for trigger events of both MCG and SCG mobility management simultaneously, without limitation in this disclosure. Alternatively, the RRCReconfiguration message configuring target cell configuration information for a terminal device may include condition-triggered cell management configuration information. This condition-triggered cell management configuration information may be condition-triggered cell management configuration information used only for SCG mobility management, such as CPA or CPC configuration; or it may be condition-triggered cell management configuration information used only for MCG mobility management, such as CHO; or it may be condition-triggered cell management configuration information used for both MCG and SCG mobility management simultaneously, such as CHO and CPC (or CPA), without limitation in this disclosure.

[0083] In addition, when configuring configuration information for condition-triggered cell management for terminal devices, network devices can also indicate the type of configuration information, so that terminal devices can distinguish the different types of configuration information for condition-triggered cell management and execute the target cell configuration corresponding to the current trigger type.

[0084] Optionally, the type of condition-triggered cell management includes at least one of the following: for primary cell group MCG mobility management; for secondary cell group SCG mobility management; for simultaneous MCG and SCG mobility management; for MCG mobility management and simultaneous MCG and SCG mobility management; for SCG mobility management and simultaneous MCG and SCG mobility management; for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management.

[0085] Specifically, "used for simultaneous MCG and SCG mobility management" means that the cell management type is simultaneous MCG and SCG mobility management. "Used for MCG mobility management, and simultaneously for MCG and SCG mobility management" means that the cell management type is either MCG mobility management or simultaneously for MCG and SCG mobility management. "Used for MCG mobility management, SCG mobility management, and simultaneously for MCG and SCG mobility management" means that the cell management type is either MCG mobility management, or SCG mobility management, or simultaneously for MCG and SCG mobility management.

[0086] In this disclosure, the network device sends configuration information for condition-triggered cell management and the type of condition-triggered cell management to the terminal device. Therefore, by configuring mobility management configurations for the MCG and / or SCG for the terminal device, the terminal device can trigger CHO and / or CPA, or CHO and / or CPC, based on the triggering conditions, thereby improving the reliability of the MCG mobility process and the SCG mobility process.

[0087] Please see Figure 3 , Figure 3 This is a flowchart illustrating a mobility management configuration method provided in an embodiment of this disclosure, which is executed by a terminal device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0088] Step 301: Receive configuration information for condition-triggered cell management and the type of condition-triggered cell management sent by the network device.

[0089] Optionally, the configuration information for condition-triggered cell management may include at least one of the following: mobility management triggering event, target cell configuration, and the association between mobility management triggering event and target cell configuration.

[0090] The mobility management trigger event can be any event that meets a specific measurement result. For example, the Reference Signal Received Power (RSRP) value of the target cell exceeds a threshold.

[0091] Optionally, the mobility management trigger event may include at least one of the following: a trigger event for MCG mobility management; a trigger event for SCG mobility management; a trigger event for simultaneous MCG and SCG mobility management; a trigger event for both MCG and SCG mobility management; a trigger event for both SCG and MCG mobility management; and a trigger event for both MCG and SCG mobility management.

[0092] The triggering events used for simultaneous MCG and SCG mobility management include any one of the following: a triggering event for evaluating MCG mobility; a triggering event for evaluating SCG mobility; or multiple triggering events for evaluating MCG mobility and triggering events for evaluating SCG mobility.

[0093] That is, the triggering event may be used only to evaluate MCG mobility assessment, without evaluating the measurement results of SCG cells; or it may be used only to evaluate SCG mobility assessment, without evaluating the measurement results of MCG cells; or it may include multiple events, among which there are triggering events for evaluating MCG mobility and triggering events for evaluating SCG mobility.

[0094] Among them, there can be one or more mobility management triggering events associated with the target cell configuration.

[0095] Optionally, if the triggering events used for simultaneous MCG and SCG mobility management include multiple triggering events for evaluating MCG mobility and multiple triggering events for evaluating SCG mobility, the terminal device may apply the target cell configuration when all multiple triggering events are satisfied, or it may apply the target cell configuration when any one of the multiple triggering events is satisfied, etc. This disclosure does not limit this.

[0096] Additionally, trigger events used for MCG mobility management and simultaneous MCG and SCG mobility management refer to events that can be used to trigger MCG mobility management, or to determine the triggering of MCGs within simultaneous MCG and SCG mobility management. For example, if the trigger event for MCG switching is A1, and the trigger event for SCG change or addition is A2, then when both the trigger event A1 for MCG switching and the trigger event A2 for SCG change or addition are satisfied, the A1+A2 event can be used to trigger simultaneous MCG mobility management and SCG mobility management.

[0097] Correspondingly, trigger events used for SCG mobility management and simultaneous MCG and SCG mobility management refer to events that can be used to trigger SCG mobility management, or events that can be used to determine the triggering of SCGs in simultaneous MCG and SCG mobility management. For example, if the trigger event for SCG change or addition is A3, and the trigger event for MCG switching is A4, then when both the trigger event A3 for SCG change or addition and the trigger event A4 for MCG switching are satisfied, the A3+A4 event can be used to trigger simultaneous MCG mobility management and SCG mobility management.

[0098] Furthermore, trigger events used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management refer to events that can trigger MCG mobility management, SCG mobility management, or the SCG triggering decision within simultaneous MCG and SCG mobility management. For example, trigger event A5 can trigger SCG change or addition, or trigger MCG switching; trigger event A1 can trigger MCG switching; and trigger event A3 can trigger SCG change or addition. When trigger events A5 and A1 are both satisfied, they can be used to trigger simultaneous MCG and SCG mobility management. Conversely, when trigger events A5 and A3 are both satisfied, the A3+A5 event can be used to trigger simultaneous MCG and SCG mobility management.

[0099] Optionally, the target cell configuration includes at least one of the following: target cell configuration information for MCG mobility management; target cell configuration information for SCG mobility management; target cell configuration information for simultaneous MCG and SCG mobility management; target cell configuration information for both MCG and SCG mobility management; target cell configuration information for both SCG and MCG mobility management; and target cell configuration information for both MCG and SCG mobility management.

[0100] Specifically, target cell configuration information used for simultaneous MCG and SCG mobility management refers to target cell configuration information used for both MCG and SCG mobility management simultaneously. Target cell configuration information used for both MCG mobility management and simultaneous MCG and SCG mobility management refers to target cell configuration information that can be used for both MCG and simultaneous MCG and SCG mobility management. Correspondingly, target cell configuration information used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management refers to target cell configuration information that can be used for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management.

[0101] For example, if the configuration information for condition-triggered cell management includes a triggering event for evaluating MCG mobility and target cell configuration information for MCG mobility management, then the terminal device can execute the corresponding target cell configuration information for MCG mobility management after the triggering event is met.

[0102] Alternatively, if the configuration information for condition-triggered cell management includes: target cell configuration information for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management, then the terminal device can execute the target cell configuration information when it determines that the execution conditions for CHO are met, or it can execute the target cell configuration information when it determines that the execution conditions for CHO and CPC (or CPA) are met, or it can execute the target cell configuration information when it determines that the execution conditions for CPA are met, and so on.

[0103] Optionally, the network device can configure target cell configuration information for MCG mobility management and target cell configuration information for SCG mobility management for the terminal device in a single message. For example, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are included in a Radio Resource Control (RRCReconfiguration) message that is used to configure both MCG and SCG.

[0104] Alternatively, different messages can be used to configure the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management separately for the terminal device. For example, the target cell configuration information for MCG mobility management can be included in the Radio Resource Control (RRCReconfiguration) message used to configure MCG, while the target cell configuration information for SCG mobility management can be included in the RRCReconfiguration message used to configure SCG.

[0105] That is, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are contained in different messages; or, the target cell configuration information for MCG mobility management and the target cell configuration information for SCG mobility management are contained in the same message.

[0106] Optionally, the target cell configuration may also include mobility management trigger events, or condition-triggered cell management configuration information.

[0107] For example, the RRCReconfiguration message configuring target cell configuration information for a terminal device may include mobility management trigger event configuration. This mobility management trigger event configuration may be used only for SCG mobility management trigger events; or it may be used only for MCG mobility management trigger events; or it may be used for trigger events of both MCG and SCG mobility management simultaneously, without limitation in this disclosure. Alternatively, the RRCReconfiguration message configuring target cell configuration information for a terminal device may include condition-triggered cell management configuration information. This condition-triggered cell management configuration information may be condition-triggered cell management configuration information used only for SCG mobility management, such as CPA or CPC configuration; or it may be condition-triggered cell management configuration information used only for MCG mobility management, such as CHO; or it may be condition-triggered cell management configuration information used for both MCG and SCG mobility management simultaneously, such as CHO and CPC (or CPA), without limitation in this disclosure.

[0108] In addition, when configuring configuration information for condition-triggered cell management for terminal devices, network devices can also indicate the type of configuration information, so that terminal devices can distinguish the different types of configuration information for condition-triggered cell management and execute the target cell configuration corresponding to the current trigger type.

[0109] Optionally, the type of condition-triggered cell management includes at least one of the following: for primary cell group MCG mobility management; for secondary cell group SCG mobility management; for simultaneous MCG and SCG mobility management; for MCG mobility management and simultaneous MCG and SCG mobility management; for SCG mobility management and simultaneous MCG and SCG mobility management; for MCG mobility management, SCG mobility management, and simultaneous MCG and SCG mobility management.

[0110] Specifically, "used for simultaneous MCG and SCG mobility management" means that the cell management type is simultaneous MCG and SCG mobility management. "Used for MCG mobility management, and simultaneously for MCG and SCG mobility management" means that the cell management type is either MCG mobility management or simultaneously for MCG and SCG mobility management. "Used for MCG mobility management, SCG mobility management, and simultaneously for MCG and SCG mobility management" means that the cell management type is either MCG mobility management, or SCG mobility management, or simultaneously for MCG and SCG mobility management.
