[0018] The following describes in detail a method for performing target operations according to the embodiments of the present application through specific embodiments and application scenarios thereof in conjunction with the drawings.

[0019] As shown in FIG. 2, one embodiment of the present invention provides a method 200 for performing a target operation, which may be performed by a terminal device, in other words, the method 200 may be performed by software or hardware installed in the terminal device, and the method 200 includes the following steps:

[0020] S202: Perform a first target operation if a conditional relocation parameter and / or an SCG deactivation command is received on a first receiving occasion.

[0021] Here, the first receiving occasion includes at least one of an occasion when the SCG is in a deactivation period and, at the same time, a occasion when a conditional relocation-related flow is being performed.

[0022] Conditional relocation includes CPC configuration for the UE to execute a CPC flow, where the CPC configuration may include a number of candidate Primary Secondary Cells (PSCells), an execution condition or trigger event for executing CPC corresponding to each candidate PSCell, and a Radio Resource Control (RRC) relocation message or parameter corresponding to each candidate PSCell.

[0023] The conditional relocation related flow may include a conditional relocation evaluation flow and a conditional relocation execution flow, for example, a CPC evaluation flow and a CPC execution flow. Specifically, after receiving the CPC configuration, the UE maintains a connection with the source PSCell and starts to execute the conditional relocation evaluation flow (which may be considered as a CPC evaluation flow), i.e., evaluates whether the execution condition or trigger event of the candidate PSCell(s) is satisfied. In the CPC evaluation process, when the execution condition or trigger event corresponding to a candidate PSCell is satisfied, the candidate PSCell is considered to be triggered. If there is at least one triggered candidate PSCell or the execution condition or trigger event corresponding to at least one PSCell is satisfied, the UE initiates the conditional relocation execution flow (i.e., the CPC execution flow). That is, the UE selects one of the triggered PSCells and initiates random access to the PSCell using the corresponding RRC configuration. When SRB3 is configured, the UE can directly send an RRCReconfigurationComplete message to the selected PSCell; when SRB3 is not configured, the UE sends a ULInformationTransferMRDC to the MN, which carries an RRCReconfigurationComplete message to be sent to the selected PSCell, and the CPC execution flow ends after sending the above message.

[0024] Regarding the SCG deactivation command, Dual Connectivity (DC) refers to providing the UE with the resources of two network nodes (access network network elements), where one network node is called a Master node (MN) and another node is called a Secondary node (SN). Each network node uses Carrier Aggregation (CA), that is, it configures a set of serving cells, also called cell groups, controlled by the node to the UE. The Master node MN controls the Master Cell Group (MCG), and the secondary node SN controls the Secondary Cell Group (SCG). Each cell group includes a Special Cell (SpCell) and a set of Secondary Cells (Scell). In the MCG, the special cell is called a Primary Cell (PCell), and in the SCG, the special cell is called a Primary Secondary Cell (PSCell). In one cell group, the SpCell uses the primary carrier, and the other secondary cells use the secondary carrier, and resource scheduling in one cell group is performed by the SpCell.

[0025] Based on this, an SCG suspended state is introduced, and when the UE has low or no data transmission for a certain period of time, the network may suspend the SCG for a while, without directly deleting the SCG and re-adding it when a relatively large amount of data appears. By suspending the SCG for a while, the terminal device can operate in a more power-saving manner for a relatively long period of time, and can recover the SCG relatively quickly when there is a large data demand, and in one implementation, it is also called an SCG deactivation state. In the SCG deactivation state, some actions on the SCG of the UE are restricted in order to save UE power consumption, for example, during the SCG deactivation period, the UE does not monitor the PDCCH (including the PSCell) on the SCG.

[0026] Then, when the UE receives the conditional relocation parameter and / or the SCG deactivation command in the first receiving occasion, if the UE cannot determine the UE behavior, it may perform conditional relocation and may perform SCG deactivation, which may cause some bad effects due to the mismatch of understanding of the transmission between the network and the UE. For example, during the period when the UE performs CPC, the UE receives the SCG deactivation command, and the UE chooses to continue performing CPC and ignore the SCG deactivation command, but the network side thinks that the UE has performed the SCG deactivation command, which causes the UE to continue monitoring the physical downlink control channel (PDCCH) of the SCG, but the SN does not actually schedule the UE, which causes the UE to waste power. Or, for example, in some scenarios, it may further cause data transmission failure between the network and the UE, etc.

[0027] In view of this, in this step, the first target operation includes at least one of not starting the conditional relocation evaluation flow, stopping the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, continuing the conditional relocation evaluation flow, not starting the conditional relocation execution flow if a first condition is met, stopping the conditional relocation execution flow if a first condition is met, postponing the start of the conditional relocation evaluation flow, postponing the start of the conditional relocation execution flow if a first condition is met, ignoring the conditional relocation parameter, deleting the conditional relocation parameter, activating or deactivating an SCG, and ignoring the SCG deactivation command.

[0028] In one embodiment, the UE does not initiate the conditional relocation evaluation flow and does not initiate the conditional relocation execution flow even if the first condition is satisfied, which may directly indicate that the UE does not initiate the conditional relocation related flows or stops the conditional relocation related flows, including the conditional relocation evaluation flow, the conditional relocation execution flow, and any sub-flows related to the conditional relocation message / parameters.

[0029] In one implementation, postponing the initiation of the conditional relocation execution flow includes at least one of the following:

[0030] The conditional relocation execution flow is initiated when there is data or signaling to be transmitted on an SCG bearer, a secondary node terminated bearer (SN terminated bearer) or an MCG bearer.

[0031] When the SCG is activated, it initiates the conditional relocation execution flow.

[0032] When an SCG activate command is received, the conditional relocation execution flow is started.

[0033] When the SCG is in a deactivation period and the MCG radio link fails, the conditional relocation execution flow is started. At this time, if there are triggered PSCells, the UE can select one of the triggered PSCells and start random access on it. In the process of accessing the selected PSCell or after completing the access, the SCG may be activated or the UE may implicitly convey the indication information to instruct the network to activate the SCG. In addition, the UE may further indicate MCG failure information to the network side, for example, the UE instructs the PSCell to activate the SCG and report MCG failure information in the access process, or the UE reports MCG failure information after access (RRC relocation message, MCG failure information).

[0034] In one implementation, postponing the initiation of the conditional relocation evaluation flow includes saving a CPC configuration, setting a target parameter as a predetermined value, and initiating a conditional relocation evaluation flow and / or a conditional relocation execution flow when a second condition is met, where the second condition includes at least one of after an SCG is activated, receiving an SCG activation command and the target parameter is the predetermined value, and / or the SCG is in a deactivation period and the MCG radio link has failed.

[0035] For example, when the SCG is in a deactivation period and receives a conditional relocation parameter, the conditional relocation parameter includes related information of a candidate PSCell, the UE decides to postpone the conditional relocation evaluation flow and sets a target parameter PendingCPC=TRUE. Then, when the UE receives an SCG activation command and PendingCPC=TRUE, the UE can activate the SCG and start the CPC evaluation flow.

[0036] In one implementation, the first condition includes when a candidate cell indicated in at least one conditional rearrangement is triggered or when a trigger event corresponding to a candidate cell indicated in at least one conditional rearrangement is satisfied.

[0037] In one implementation, the conditional relocation execution flow includes the following:

[0038] A first target cell is determined that includes a cell indicated in the conditional rearrangement.

[0039] Using an RRC relocation message or parameters corresponding to the first target cell.

[0040] Synchronization is established with the first target cell.

[0041] Initiate random access to the first target cell.

[0042] Send an RRC message to the first target cell.

[0043] Thereby, a method of executing a target operation according to an embodiment of the present invention executes a first target operation when a conditional relocation parameter and / or an SCG deactivation command is received at a first receiving occasion, where the first receiving occasion includes at least one of an occasion when an SCG is in a deactivation period and at the same time, an occasion when a conditional relocation related flow is being performed, and the first target operation includes not starting a conditional relocation evaluation flow, stopping the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, continuing to perform the conditional relocation evaluation flow, not starting a conditional relocation execution flow when a first condition is satisfied, and executing a conditional relocation execution flow when a first condition is satisfied. the step of determining whether the conditional relocation parameter is set to "ON" or "OFF" includes at least one of: stopping the conditional relocation execution flow when a first condition is met, postponing the start of the conditional relocation evaluation flow when a first condition is met, postponing the start of the conditional relocation execution flow when a first condition is met, ignoring the conditional relocation parameter, deleting the conditional relocation parameter, activating or deactivating an SCG, and ignoring the SCG deactivation command, so that when the two functions of conditional relocation and SCG deactivation are configured by the network or instructed to the UE simultaneously or one after the other, the behavior of the UE can be clarified, the understanding between the network and the UE can be consistent, and adverse effects caused by inconsistent understanding on transmission between the network and the UE can be avoided.

[0044] As shown in FIG. 3, one embodiment of the present invention provides a method 300 for performing a target operation, which may be performed by a terminal device, in other words, the method 300 may be performed by software or hardware installed in the terminal device, and the method 300 includes the following steps:

[0045] S302: If the SCG is in a deactivation period and receives a conditional relocation parameter, perform a first target operation.

[0046] At this time, when the SCG is in a deactivation period and receives a conditional relocation parameter, if it cannot determine the UE behavior, it may perform conditional relocation and may also perform SCG deactivation, which may have an impact between the two functions and may bring about some adverse effects due to a mismatch in understanding of transmission between the network and the UE.

[0047] In view of this, in this step, the first target operation includes at least one of not starting the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, not starting the conditional relocation execution flow if a first condition is met, postponing the start of the conditional relocation evaluation flow, postponing the start of the conditional relocation execution flow if a first condition is met, ignoring the conditional relocation parameters, and activating an SCG.

[0048] In one embodiment, when the SCG is in a deactivated state period and the UE receives a conditional relocation parameter including a candidate PSCell, the UE considers that the PSCell relocation parameter implicitly instructs the UE to activate the SCG, and so the UE activates the SCG and initiates a CPC evaluation flow upon receiving the conditional relocation parameter.

[0049] The specific implementation manner of each flow included in the above first target operation may adopt the same description as in the embodiment of FIG. 2, and will not be described further here.

[0050] Thus, a method for executing a target operation according to an embodiment of the present invention performs a first target operation when an SCG is in a deactivation period and receives a conditional relocation parameter, where the first target operation includes at least one of: not initiating the conditional relocation evaluation flow; starting the conditional relocation evaluation flow; not initiating the conditional relocation execution flow when a first condition is met; postponing the start of the conditional relocation evaluation flow; postponing the start of the conditional relocation execution flow when a first condition is met; ignoring the conditional relocation parameter; and activating an SCG, so as to clarify the behavior of the UE and align the understanding between the network and the UE when the SCG is in a deactivation period and receives a conditional relocation parameter, and to avoid adverse effects caused by inconsistent understanding on transmission between the network and the UE.

[0051] As shown in FIG. 4 , one embodiment of the present invention provides a method 400 for performing a target operation, which may be performed by a terminal device, in other words, the method 400 may be performed by software or hardware installed in the terminal device, and the method 400 includes the following steps:

[0052] S402: Perform a first target operation if a conditional relocation parameter and / or an SCG deactivation command is received on a first receiving occasion.

[0053] The receiving of a conditional relocation parameter and / or an SCG deactivation command at the first receiving occasion includes receiving the conditional relocation parameter and the SCG deactivation command simultaneously, or receiving the SCG deactivation command when obtaining the conditional relocation parameter and not executing the conditional relocation-related flow.

[0054] If the UE behavior cannot be determined when receiving the conditional relocation parameters and / or the SCG deactivation command on the first receiving occasion, the conditional relocation may be performed and also the SCG deactivation may be performed, which may cause an impact between the two functions and may result in some adverse effects due to a mismatch in understanding of transmission between the network and the UE.

[0055] In view of this, in this step, the first target operation includes at least one of not starting the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, not starting the conditional relocation execution flow if a first condition is met, postponing the start of the conditional relocation evaluation flow, postponing the start of the conditional relocation execution flow if a first condition is met, ignoring the conditional relocation parameter, deleting the conditional relocation parameter, and ignoring the SCG deactivation command.

[0056] In one embodiment, the UE receives a conditional relocation including a candidate PSCell and then receives an SCG deactivation command, and the UE considers that the SCG deactivation command sent by the network has implicitly instructed the UE to stop execution of any flows associated with the CPC or delete the associated conditional relocation parameters.

[0057] The specific implementation manner of each flow included in the above first target operation may adopt the same description as in the embodiment of FIG. 2, and will not be described further here.

[0058] Thereby, a method for performing a target operation according to an embodiment of the present invention performs a first target operation when a conditional relocation parameter and / or an SCG deactivation command is received at a first receiving occasion, and the first target operation includes at least one of: not starting the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, not starting the conditional relocation execution flow when a first condition is met, postponing the start of the conditional relocation evaluation flow, postponing the start of the conditional relocation execution flow when a first condition is met, ignoring or deleting the conditional relocation parameter, and ignoring the SCG deactivation command, so as to clarify the behavior of the UE when the conditional relocation parameter and the SCG deactivation command are received simultaneously or when the conditional relocation parameter is obtained and the conditional relocation related flow is not executed, and to achieve consistent understanding between the network and the UE, and to avoid adverse effects caused by inconsistent understanding on transmission between the network and the UE.

[0059] As shown in FIG. 5 , one embodiment of the present invention provides a method 500 for performing a target operation, which may be performed by a terminal device, in other words, the method 500 may be performed by software or hardware installed in the terminal device, and the method 500 includes the following steps:

[0060] S502: When an SCG deactivation command is received during a conditional relocation-related flow, a first target operation is executed.

[0061] If the UE behavior cannot be determined when an SCG deactivation command is received while a conditional relocation related flow is in progress, it may perform conditional relocation and may also perform SCG deactivation, which may have an impact between the two functions and may result in some adverse effects due to a mismatch in understanding of transmission between the network and the UE.

[0062] In view of this, in this step, the first target operation includes at least one of stopping the conditional relocation evaluation flow, continuing to perform the conditional relocation evaluation flow, stopping the conditional relocation execution flow if a first condition is met, postponing start of the conditional relocation execution flow if a first condition is met, ignoring the SCG deactivation command, and deleting the conditional relocation parameter.

[0063] In one embodiment, when the UE is performing a CPC evaluation flow and receives an SCG deactivation command, the UE stops the CPC evaluation flow that is being performed. Optionally, the UE may delete the CPC conditional relocation parameter, or the UE may not delete it and restart the CPC evaluation flow after the SCG is activated.

[0064] The specific implementation manner of each flow included in the above first target operation may adopt the same description as in the embodiment of FIG. 2, and will not be described further here.

[0065] As a result, a method for executing a target operation according to an embodiment of the present invention performs a first target operation when an SCG deactivation command is received when a conditional relocation related flow is in progress, and the first target operation includes at least one of stopping the conditional relocation evaluation flow, continuing to perform the conditional relocation evaluation flow, stopping the conditional relocation execution flow when a first condition is met, postponing start of the conditional relocation execution flow when a first condition is met, ignoring the SCG deactivation command, and deleting the conditional relocation parameters, thereby clarifying the UE's behavior when an SCG deactivation command is received when a conditional relocation related flow is in progress, aligning the understanding between the network and the UE, and avoiding adverse effects caused by inconsistent understanding on transmission between the network and the UE.

[0066] It should be noted that, for the target operation execution method according to the embodiment of the present application, the execution body may be a target operation execution device, or may be a control module for executing and loading the above method in the device. In the embodiment of the present application, the target operation execution method according to the embodiment of the present application is described by taking the target operation execution device executing and loading the target operation execution method as an example.

[0067] 6 is a structural schematic diagram of a target operation execution device according to an embodiment of the present invention. As shown in FIG. 6, the target operation execution device 600 includes an execution module 610.

[0068] The execution module 610 is used to execute a first target operation when receiving a conditional relocation parameter and / or an SCG deactivation command at a first receiving occasion, where the first receiving occasion includes at least one of an occasion when the SCG is in a deactivation period and at the same time when a conditional relocation related flow is being performed, and the first target operation includes at least one of: not starting a conditional relocation evaluation flow, stopping the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, continuing to perform the conditional relocation evaluation flow, not starting a conditional relocation execution flow if a first condition is met, stopping the conditional relocation execution flow if a first condition is met, postponing the start of the conditional relocation evaluation flow, postponing the start of the conditional relocation execution flow if a first condition is met, ignoring the conditional relocation parameter, deleting the conditional relocation parameter, activating or deactivating an SCG, and ignoring the SCG deactivation command.

[0069] In one implementation, the target operation execution device 600 may further include a receiving module for receiving a conditional relocation parameter and / or an SCG deactivation command.

[0070] In one implementation, the execution module 610 is used to execute a first target operation when the SCG is in an inactivation period and receives a conditional relocation parameter, where the first target operation includes at least one of: not starting the conditional relocation evaluation flow; starting the conditional relocation evaluation flow; not starting the conditional relocation execution flow when a first condition is met; postponing the start of the conditional relocation evaluation flow; postponing the start of the conditional relocation execution flow when a first condition is met; ignoring the conditional relocation parameter; and activating an SCG.

[0071] In one implementation, the execution module 610 executing a first target operation when receiving a conditional relocation parameter and / or an SCG deactivation command at a first receiving occasion includes executing a first target operation when receiving a conditional relocation parameter and / or an SCG deactivation command at a first receiving occasion, the first target operation including not starting the conditional relocation evaluation flow, starting the conditional relocation evaluation flow, not starting the conditional relocation execution flow when a first condition is satisfied, and postponing the start of the conditional relocation evaluation flow. the receiving occasion includes at least one of: expecting to start the conditional relocation execution flow when a first condition is met; postponing initiation of the conditional relocation execution flow; ignoring or deleting the conditional relocation parameter; and ignoring the SCG deactivation command when a first condition is met, wherein receiving the conditional relocation parameter and / or the SCG deactivation command at the first receiving occasion includes receiving the conditional relocation parameter and the SCG deactivation command simultaneously, or receiving the SCG deactivation command when obtaining the conditional relocation parameter and not executing the conditional relocation related flow.

[0072] In one implementation, executing a first target operation when the execution module 610 receives a conditional relocation parameter and / or an SCG deactivation command at a first receiving occasion includes executing a first target operation when an SCG deactivation command is received when a conditional relocation related flow is in the middle of being performed, the first target operation including at least one of stopping the conditional relocation evaluation flow, continuing to perform the conditional relocation evaluation flow, stopping the conditional relocation execution flow if a first condition is met, postponing start of the conditional relocation execution flow if a first condition is met, ignoring the SCG deactivation command, and deleting the conditional relocation parameter.
