[0037] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numerals in different accompanying drawings refer to the same or similar elements unless otherwise specified. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely illustrative of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0038] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms unless the context clearly dictates otherwise. Also, as used herein, the term "and / or" should be understood to refer to and include any and all possible combinations of at least one of the associated listed items.

[0039] In this disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are used only to distinguish between the same types of information. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of this disclosure. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination." Before describing the solution provided by the present disclosure, the modification of a dynamic cell (or a dynamic cell group) will be described.

[0040] In a 5th Generation Mobile Communication Technology (5G) system, a network side device may provide a terminal with multiple candidate cells (or candidate cell groups). The network side device can then control the terminal to change among the multiple candidate cells (or candidate cell groups) through L1 or L2 signaling, for example, to change the working cell (or working cell group) from candidate cell #1 (or candidate cell group #1) to candidate cell #2 (or candidate cell group #2).

[0041] Here, L1 signaling includes, but is not limited to, Downlink Control Information (DCI), and L2 signaling includes, but is not limited to, Media Access Control Elements (MAC CE).

[0042] Here, one serving cell (or serving cell group) can correspond to one or more candidate cells (or candidate cell groups).

[0043] In a 5G system with Dual Connectivity (DC) architecture, there are two subgroups of cells (or cell groups): A Master Cell Group (MCG) corresponds to a Master Node (MN) on the network side; A secondary cell group (SCG) corresponds to a secondary node (SN) on the network side.

[0044] An MCG includes one Primary Cell (PCell) and one or more Secondary Cells (SCells), and an SCG includes one Primary Secondary Cell (PSCell) and one or more SCells. PCells and PSCells can be collectively referred to as Special Cells (SpCells).

[0045] In the current system, one cell (or cell group) is assigned one serving cell configuration (or serving cell group configuration), i.e., ServCellConfig. The serving cell configuration (or serving cell group configuration) is associated with a serving cell identifier (or serving cell group identifier), i.e., ServCellIndex, which is used to uniquely identify one serving cell (or serving cell group) in a terminal. The identifier of the serving cell (or serving cell group) of the PCell is "0". One serving cell (or serving cell group) is associated with a Hybrid Automatic Repeat Request (HARQ) entity that includes multiple HARQ processes.

[0046] In addition, in a 5G system, a terminal can change a serving cell (or a serving cell group) based on a condition preset by a network side and a preset cell (or a cell group) corresponding to the condition. For example, when a terminal satisfies a preset condition such as a specific measurement event, the terminal changes the serving cell (or serving cell group) to a preset cell (or a cell group). Here, the mobility process triggered based on the condition is: Conditional Handover (CHO) and Conditional Primary and Secondary Cell (or Cell Group) Addition (Conditional PSCell Addition, CPA); and Conditional Primary and Secondary Cell (or Cell Group) Change (Conditional PSCell Change, CPC).

[0047] After a preset condition is satisfied, the terminal can change a specific cell configuration (or cell group configuration) according to an instruction from the network side device. For example, the terminal changes its PCell configuration from candidate cell configuration #1 (or candidate cell group configuration 1) to candidate cell configuration #2 (or candidate cell group configuration 2).

[0048] The following provides a detailed explanation of the connection issues involved.

[0049] There are several types of device connection issues: Switchover failure, e.g., switchover is not completed within the specified time corresponding to the timeout of timer t304; Secondary Cell Group (SCG) change failure, e.g., access to the new SCG is not completed within the specified time corresponding to the timeout of timer t307; Cell change failure, e.g., cell change not completed within the specified time; Cell activation failure, e.g., cell activation is not completed within the specified time; Radio Link Failure (RLF); Wherein the failure of the wireless link includes: Physical layer out of sync, e.g. timer t310 expired; Media Access Control (MAC) layer random access failure, e.g., the maximum number of random access attempts has been reached; The Radio Link Control (RLC) layer has reached the maximum number of retransmission instructions, e.g., the maximum number of retransmission attempts in the RLC layer has been reached; Beam failure, e.g., the beam failure detection mechanism detects the occurrence of a beam failure, and at that time the beam failure counter reaches a threshold; To detect loss of physical layer synchronization, e.g., Radio Link Monitoring (RLM) or Beam Failure Detection (BFD), the terminal needs to monitor the signals corresponding to that RLM, e.g., Synchronization Signal Block (SSB) or Channel State Information-Reference Signal (CSI-RS).

[0050] In order to solve the technical problems of the present disclosure, the present disclosure provides the following detection process, terminal operation determination method and device, and storage medium, which can improve the stability and availability of wireless connections.

[0051] It should be noted that in the embodiments of the present disclosure, the related candidate cells may refer to candidate cells or candidate cell groups, and the candidate cell configuration may refer to candidate cell configuration or candidate cell group configuration, and the present disclosure is not limited thereto.

[0052] The detection processing method provided by the present disclosure will be described below, starting from the terminal side.

[0053] An embodiment of the present disclosure provides a detection processing method that can be executed by a terminal and may include the following steps, as shown with reference to FIG. 1 , which is a flowchart of a detection processing method illustrated according to an embodiment: In step 101, in response to determining that the candidate cell configuration used by the terminal has changed, it is determined based on predefined rules whether to perform connection failure detection in the target candidate cell.

[0054] In a possible embodiment, the target candidate cell may be associated with a target candidate cell configuration, where if the target candidate cell configuration includes a configuration of a particular candidate cell, then that candidate cell is a target candidate cell and the target candidate cell is associated with that target candidate cell configuration.

[0055] In an embodiment of the present disclosure, the target candidate cell configuration may be the candidate cell configuration that is activated or deactivated when the candidate cell configuration is changed.

[0056] In a possible embodiment, the terminal is triggered to change the candidate cell configuration used in response to receiving change instruction information sent by a network side device, the change instruction information being used to instruct the terminal to change the candidate cell configuration used, i.e. to trigger the terminal to perform an operation to change the candidate cell configuration used.

[0057] For example, the change instruction information instructs the terminal to change the candidate cell setting corresponding to the terminal's PCell from candidate cell setting #1 to candidate cell setting #2, and at this time, the terminal is triggered to change the candidate cell setting used.

[0058] Optionally, the change instruction information may be a Downlink Control Information (DCI), a MAC CE, or an RRC message.

[0059] In another possible embodiment, the terminal is triggered to change the candidate cell configuration used in response to determining that a predefined candidate cell configuration change condition is met, i.e. the terminal is triggered to perform an operation to change the candidate cell configuration used.

[0060] Optionally, the candidate cell configuration change conditions may include, but are not limited to, measurement results of a terminal corresponding to a PCell that satisfies an A3 event.

[0061] In an embodiment of the present disclosure, the operation of changing the candidate cell configuration used by the terminal includes, but is not limited to, at least one of the following: The candidate cell configuration corresponding to the target candidate cell is changed; The candidate cell configuration corresponding to the target candidate cell is deactivated.

[0062] For example, if the candidate cell setting corresponding to the target candidate cell is changed, the candidate cell setting corresponding to the terminal's PCell is changed from candidate cell setting #1 to candidate cell setting #2, and accordingly, at least one of candidate cell setting #1 and candidate cell setting #2 may be used as the target candidate cell setting.

[0063] Also, for example, if the candidate cell configuration corresponding to the target candidate cell is deactivated, the candidate cell configuration #1 corresponding to the terminal's PCell may be deactivated, and accordingly, the candidate cell configuration #1 may be used as the target candidate cell configuration.

[0064] The above is merely an exemplary description, and the operations performed by the terminal whose candidate cell setting has been changed are not limited to the above operations.

[0065] In a possible embodiment, if the target candidate cell configuration is a candidate cell configuration that is activated when the candidate cell configuration is changed, the terminal decides whether to perform connection failure detection in the target candidate cell.

[0066] In another possible embodiment, if the target candidate cell configuration is a candidate cell configuration that is deactivated when the candidate cell configuration is changed, the terminal determines whether to perform connectivity failure detection in the target candidate cell.

[0067] In the above embodiment, when the candidate cell configuration used by the terminal is changed, the terminal determines whether to perform connection failure detection in the target candidate cell based on a predefined rule, and the connection failure detection and connection failure recovery may then be performed in the target candidate cell, thereby improving the stability and availability of the wireless connection.

[0068] In some optional embodiments, referring to FIG. 2 , which is a flowchart of a detection processing method shown according to an embodiment, which may be performed by a terminal, the method may include the following steps: In step 201, in response to determining that the configuration of the candidate cell used by the terminal has been changed, it is determined whether to perform connection failure detection in the target candidate cell based on network configuration indication information sent by a network side device.

[0070] In an embodiment of the present disclosure, the target candidate cell configuration is the candidate cell configuration that is activated or deactivated when the candidate cell configuration is changed.

[0071] In the embodiment of the present disclosure, the conditions triggering the terminal to perform the operation of changing the candidate cell configuration used by the terminal and the specific actions of performing the action of changing the candidate cell configuration used by the terminal are similar to those described in step 101 above and will not be repeated here.

[0072] In an embodiment of the present disclosure, the network setting indication information is used to indicate whether the terminal needs to perform connectivity failure detection in the target candidate cell.

[0073] In a possible embodiment, the network side device may transmit candidate cell configuration information to the terminal, and this candidate cell configuration information is used by the network side device to provide the terminal with one or more candidate cell configurations. Optionally, the network side device may transmit this candidate cell configuration information via an RRCReconfiguration message. The terminal can determine whether the candidate cell configuration has changed based on the candidate cell configuration information.

[0074] In an embodiment of the present disclosure, the network configuration instruction information may be included in the candidate cell configuration information.

[0075] In another possible embodiment, the network side device may transmit change instruction information to the terminal, which is used to instruct the terminal to change the candidate cell configuration used, for example, to change the candidate cell configuration of the terminal's PCell from candidate cell configuration #1 to candidate cell configuration #2.

[0076] In an embodiment of the present disclosure, the network setting instruction information may be included in the change instruction information.

[0077] By multiplexing existing information and transmitting this network setting instruction information, the signaling resources of the network side device can be effectively saved, and the implementation is easy and the availability is high.

[0078] In a possible embodiment, when the network setting instruction information is used to indicate that the terminal needs to perform connectivity failure detection in the target candidate cell, the terminal decides to perform connectivity failure detection in the target candidate cell based on the network setting instruction information.

[0079] In another possible embodiment, when the network setting indication information is used to indicate that the terminal does not need to perform connectivity failure detection in the target candidate cell, the terminal decides not to perform connectivity failure detection in the target candidate cell based on the network setting indication information.

[0080] In the above embodiment, when the configuration of the candidate cell used by the terminal is changed, the terminal can determine whether to perform connection failure detection in the target candidate cell based on the network configuration instruction information sent from the network side device, and then perform connection failure detection and connection failure recovery in the target candidate cell, thereby improving the stability and availability of the wireless connection.

[0083] In an embodiment of the present disclosure, the target candidate cell configuration is the candidate cell configuration that is activated or deactivated when the candidate cell configuration is changed.

[0084] In the embodiment of the present disclosure, the conditions triggering the terminal to perform the operation of changing the candidate cell configuration used by the terminal and the specific operation of changing the candidate cell configuration used by the terminal are similar to those described in step 101 above, and will not be repeated here.

[0085] In an embodiment of the present disclosure, the designated type is a type of cell or cell group that requires connectivity failure detection as agreed upon by a protocol, i.e., when the terminal determines that the candidate cell configuration used has changed, the terminal may determine whether to perform connectivity failure detection in the target candidate cell based on the protocol agreement.

[0087] In a possible embodiment, the cell type of the target candidate cell belongs to one of the specified types, and the terminal decides to perform connection failure detection in the target candidate cell.

[0088] Also, in another possible embodiment, if the cell type of the target candidate cell does not belong to any of the specified types, the terminal decides not to perform connection failure detection in the target candidate cell.

[0089] In the above embodiment, when the configuration of the candidate cell used by the terminal is changed, the terminal may determine whether to perform connection failure detection in the target candidate cell based on the protocol agreement, and may perform connection failure detection and connection failure recovery in the target candidate cell in a subsequent period, so as to improve the stability and availability of the wireless connection.

[0090] In some optional embodiments, referring to FIG. 4 , which is a flowchart of a detection processing method shown according to an embodiment, which may be performed by a terminal, the method may include the following steps: In step 401, in response to determining that a change has occurred in the configuration of a candidate cell used by the terminal, it is determined whether to perform connection failure detection in the target candidate cell based on the network configuration indication information and whether the cell type of the target candidate cell belongs to the specified type.

[0091] In an embodiment of the present disclosure, the target candidate cell is associated with a target candidate cell configuration, where if the target candidate cell configuration includes a configuration of a specific candidate cell, the candidate cell is a target candidate cell, and the target candidate cell is associated with the target candidate cell configuration.

[0092] In an embodiment of the present disclosure, the target candidate cell configuration is the candidate cell configuration that is activated or deactivated when the candidate cell configuration is changed.

[0093] In the embodiment of the present disclosure, the conditions for the operations triggered to perform a change in the candidate cell configuration used by the terminal and the specific operations for performing a change in the candidate cell configuration used by the terminal are similar to those described in step 101 above, and will not be repeated here.

[0095] That is, when the terminal determines that the configuration of the candidate cell to be used has been changed, the terminal can jointly decide whether to perform connection failure detection in the target candidate cell based on the network configuration instruction information and protocol agreement transmitted from the network side device.

[0096] In possible embodiments, the designated type includes, but is not limited to, at least one of a primary cell PCell, a primary and secondary cell PSCell, a special cell SpCell, and a primary cell group MCG.

[0097] In a possible embodiment, if the cell type of the target candidate cell belongs to one of the specified types and the network configuration instruction information indicates that the terminal needs to perform connection failure detection in the target candidate cell, the terminal decides to perform connection failure detection in the target candidate cell.

[0098] In another possible embodiment, the cell type of the target candidate cell does not belong to any of the specified types, and the terminal decides not to perform connectivity failure detection in the target candidate cell, even if the network configuration instruction information indicates that connectivity failure detection needs to be performed in the target candidate cell.

[0101] In the above embodiment, when the configuration of the candidate cell used by the terminal is changed, the terminal may jointly determine whether to perform connection failure detection in the target candidate cell according to the network configuration instruction information sent from the network side device and the protocol agreement, and then perform connection failure detection and connection failure recovery in the target candidate cell, thereby improving the stability and high availability of the wireless connection.

[0102] In some optional embodiments, the network setting instruction information sent by the network side device to the terminal may further include fault setting information, which is information set by the network side device to enable the terminal to perform connection fault detection and / or connection fault recovery.

[0103] For example, the fault setting information is included in a MAC CE that includes change instruction information for the network setting instruction information.

[0105] Specifically, the beam identifier includes at least one of an SSB identifier and a CSI-RS identifier.

[0106] In the above embodiment, the network setting instruction information transmitted from the network side device to the terminal may carry connection failure detection information and / or connection failure recovery information configured in the terminal, so that the terminal can subsequently perform connection failure detection and connection failure recovery in the target candidate cell, thereby improving the stability and high availability of the wireless connection.

[0107] Referring to FIG. 5A, which is a flowchart of a detection processing method shown according to an embodiment, which may be performed by a terminal in some optional embodiments, the method may include the following steps: In step 501, in response to determining that the candidate cell configuration used by the terminal has changed, it is determined whether to perform connection failure detection in the target candidate cell based on predefined rules.

[0108] The specific implementation can refer to the above steps 201, 301 or 401, and will not be described herein.

[0109] In step 502, a connection failure detection is performed in the target candidate cell based on a predefined rule, and in response to determining that the target candidate cell configuration is to be deactivated, a connection failure detection is performed in the target candidate cell.

[0110] In an embodiment of the present disclosure, if the terminal performs connection failure detection in the target candidate cell based on the predefined rule (see step 201, 301 or 401) and the target candidate cell configuration is deactivated, the terminal may perform connection failure detection in the target candidate cell.

[0111] In one embodiment of the present disclosure, the operation of the terminal performing connection failure detection in the target candidate cell includes, but is not limited to, at least one of: resetting a counter corresponding to the connection failure detection process; resetting a timer corresponding to the connection failure detection process; discarding the connection failure report information; considering the connection failure recovery process to be completed successfully; and, if a change occurs in the connection failure recovery setting, stopping the ongoing connection failure recovery process and triggering a new connection failure recovery process.

[0112] Counters corresponding to the process of connection failure detection include, but are not limited to, beam failure counters and physical layer out-of-sync counters.

[0113] The timers corresponding to the process of detecting a connection failure include, but are not limited to, a beam failure detection timer and a physical layer out-of-sync timer.

[0114] Discarding the connection failure report information includes, but is not limited to, discarding a beam failure report MAC CE or discarding a radio link failure report.

[0115] Deeming the connection failure recovery process to have been completed successfully includes, but is not limited to, at least one of the following: for a beam failure recovery process, the terminal deems the beam failure recovery process to have been completed successfully; for a beam failure recovery process on an SCell, the beam failure reporting process is deems to have been completed successfully; and for a beam failure recovery process on an SCell, the random access process triggered by the beam failure is deems to have been completed successfully.

[0116] Here, if the connection failure recovery setting is changed, the terminal may stop the ongoing connection failure recovery process and trigger a new connection failure recovery process.

[0117] For example, in the beam failure recovery process of an SpCell, if the beam failure recovery setting of the SpCell is changed during the process of activating, deactivating, or changing the corresponding candidate cell setting of the SpCell, the terminal stops the ongoing beam failure recovery process (e.g., the random access process triggered by the SpCell due to beam failure recovery) and triggers a new beam failure recovery process (e.g., the random access process triggered by the SpCell due to beam failure recovery).

[0118] In the above embodiment, when the candidate cell configuration used by the terminal is changed, the terminal may determine whether to perform connection failure detection in the target candidate cell based on a predefined rule, and then the connection failure detection may be performed in the target candidate cell, thereby improving the stability and high availability of the wireless connection.

[0119] Referring to FIG. 5B, which is a flowchart of a detection processing method shown according to an embodiment, which may be performed by a terminal in some optional embodiments, the method may include the following steps: In step 501', in response to determining that the candidate cell configuration used by the terminal has changed, it is determined whether to perform connection failure detection in the target candidate cell based on predefined rules.

[0120] Specific implementations may refer to steps 201, 301 or 401 above, which will not be repeated here.

[0121] In step 502', it is determined to perform connection failure detection in the target candidate cell based on a predefined rule, and in response to the target candidate cell setting being activated, connection failure detection is performed in the target candidate cell.

[0122] In an embodiment of the present disclosure, the terminal determines to perform connection failure detection in the target candidate cell based on a predefined rule (see step 201, 301 or 401), and when the target candidate cell configuration is activated, the terminal may perform connection failure detection in the target candidate cell.

[0123] In an embodiment of the present disclosure, the target candidate cell configuration may be a candidate cell configuration that has been previously activated and is now being reactivated, or the target candidate cell configuration may be a candidate cell configuration that has not been previously activated and is now being activated, and the present disclosure is not limited thereto.

[0124] In an embodiment of the present disclosure, the operation of the terminal performing connection failure detection in the target candidate cell includes, but is not limited to, at least one of: resetting a counter corresponding to the connection failure detection process; resetting a timer corresponding to the connection failure detection process; discarding the connection failure report information; considering the connection failure recovery process to be completed successfully; and, if a change occurs in the connection failure recovery setting, stopping the ongoing connection failure recovery process and triggering a new connection failure recovery process.

[0125] Counters corresponding to the process of connection failure detection include, but are not limited to, beam failure counters and physical layer out-of-sync counters.

[0126] The timers corresponding to the process of detecting a connection failure include, but are not limited to, a beam failure detection timer and a physical layer out-of-sync timer.

[0127] Discarding the connection failure report information includes, but is not limited to, discarding the beam failure report MAC CE or discarding the radio link failure report.

[0128] Deeming the connection failure recovery process to have been completed successfully includes, but is not limited to, at least one of the following: for a beam failure recovery process, the terminal deems the beam failure recovery process to have been completed successfully; for a beam failure recovery process on an SCell, deeming the beam failure reporting process to have been completed successfully; and for a beam failure recovery process on an SCell, deeming the random access process triggered by the beam failure to have been completed successfully.

[0129] In particular, if the connection failure recovery setting is changed, the terminal may stop the ongoing connection failure recovery process and trigger a new connection failure recovery process.

[0130] For example, in a beam failure recovery process of an SpCell, if the beam failure recovery setting of the candidate cell setting corresponding to the SpCell is changed during the process of activating, deactivating, or changing the candidate cell setting corresponding to the SpCell, the terminal stops the ongoing beam failure recovery process (e.g., the SpCell triggers a beam failure recovery random access process) and triggers a new beam failure recovery process (e.g., the SpCell triggers a beam failure recovery random access process).

[0131] In the above embodiment, when the candidate cell configuration used by the terminal is changed, the terminal may determine whether to perform connection failure detection in the target candidate cell based on a predefined rule, and the connection failure detection may then be performed in the target candidate cell, thereby improving the stability and high availability of the wireless connection.

[0132] In some optional embodiments, after the terminal performs a connectivity failure detection in the target candidate cell, the terminal may be triggered to perform connectivity failure recovery.

[0133] In a possible embodiment, the terminal performs connection failure detection in the target candidate cell, and triggers the terminal to perform connection failure recovery in response to the target candidate cell configuration being reactivated after the connection failure is detected.

[0134] In another possible embodiment, a connection failure detection is performed in the target candidate cell, and in response to a connection failure being detected, the terminal is triggered to perform a connection failure recovery in a cell for which candidate cell configuration has been activated.

[0135] For example, an activated PCell reports a beam obstruction that occurs in a deactivated SCell.

[0136] In an embodiment of the present disclosure, triggering the terminal to perform recovery of a connection failure may include, but is not limited to, at least one of triggering the terminal to perform random access in the target candidate cell and triggering the terminal to report connection failure information associated with the target candidate cell.

[0137] Here, the connection failure information reported by the terminal includes at least one of a candidate cell configuration identifier corresponding to the connection failure, a candidate cell identifier corresponding to the connection failure, a connection failure type, a cell state corresponding to the connection failure, a cell configuration state corresponding to the connection failure, reference signal information corresponding to the connection failure, cell information for recovery from the connection failure, and reference signal information for recovery from the connection failure, but is not limited to these.

[0138] The candidate cell setting identifier corresponding to the connection failure refers to the identifier of the candidate cell setting in which the connection failure is detected, and the candidate cell identifier corresponding to the connection failure refers to the identifier of the candidate cell in which the connection failure is detected.

[0139] The types of connection failure include, but are not limited to, at least one of beam failure and physical layer out-of-synchronization.

[0140] Cell states corresponding to a connection failure include, but are not limited to, an activated state and a deactivated state.

[0141] The cell configuration states corresponding to a connection failure include, but are not limited to, an activated state and a deactivated state.

[0142] In an embodiment of the present disclosure, the network side device sets cell states for different candidate cells, including an activated state or a deactivated state, and a candidate cell whose cell state is set as an activated state may have an actual cell state of an activated state or a deactivated state. The cell setting state corresponding to a connection failure refers to the cell state set by the network side device for a cell in which a connection failure occurs. The cell state corresponding to a connection failure refers to the actual state of the cell in which a connection failure occurs.

[0143] Here, the reference signal information corresponding to the connection failure includes, but is not limited to, beam information corresponding to the beam failure.

[0144] The cell information for recovery from a connection failure is information related to a cell that can be used to recover from a connection failure, which is provided for the terminal by a network-side device.

[0145] The reference signal information for recovery from the connection failure includes, but is not limited to, information related to available candidate beams detected by the terminal after the occurrence of the beam failure.

[0146] In the above embodiment, when the candidate cell configuration used by the terminal is changed, the terminal determines whether to perform connection failure detection in the target candidate cell based on a preset rule, and then performs connection failure detection in the target candidate cell. If a connection failure is detected, the terminal can be triggered to perform connection failure recovery, thereby improving the stability and availability of the wireless connection.

[0147] Hereinafter, the method for determining terminal operation provided by the present disclosure will be described again from the device side on the network side.

[0175] In an embodiment of the present disclosure, the network configuration indication information is used to indicate whether the terminal needs to perform connectivity failure detection in the target candidate cell, and the designated type is the type of cell or cell group that needs to perform protocol-agreed connectivity failure detection.

[0176] That is, the network side devices can jointly determine whether the terminal needs to perform connection failure detection in the target candidate cell based on the network configuration instruction information and protocol agreement sent to the terminal.

[0187] Further examples of the above methods provided in this disclosure are described below.

[0188] In embodiment 1, the detection process and the method for determining the terminal behavior may include the following steps: Step 1: A network side device sends candidate cell configuration information to a terminal.

[0189] Here, the candidate cell configuration information is used by the network side device to provide one or more of the candidate cell configurations to the terminal, and optionally, the network side device may send the candidate cell configuration information via an RRCReconfiguration message.

[0190] Step 2: In response to determining, based on the candidate cell configuration information, that the candidate cell configuration used by the terminal has changed, the terminal determines, based on a predefined rule, whether to perform connection failure detection in the target candidate cell.

[0191] Wherein, the trigger condition for changing the candidate cell configuration used by the terminal includes any one of the following: Condition 1: The terminal receives change instruction information sent from the network side device.

[0192] For example, the change instruction information may change the candidate cell setting corresponding to the terminal's PCell from candidate cell setting #1 to candidate cell setting #2.

[0193] The change instruction information may be a DCI, MAC CE, or RRC message.

[0194] Condition 2: The terminal satisfies the predefined candidate cell setting change conditions.

[0195] Optionally, the terminal satisfies an A3 event for the measurement result of the PCell, and the terminal changes the candidate cell configuration corresponding to the PCell from #1 to candidate cell configuration #2.

[0196] In an embodiment of the present disclosure, the operation of changing the candidate cell configuration used by the terminal includes, but is not limited to, at least one of changing the candidate cell configuration corresponding to the target candidate cell and deactivating the candidate cell configuration corresponding to the target candidate cell.

[0197] In an embodiment of the present disclosure, the target candidate cell is associated with a target candidate cell configuration, where if the target candidate cell configuration includes a configuration of a specific candidate cell, the candidate cell is a target candidate cell, and the target candidate cell is associated with the target candidate cell configuration.

[0198] In an embodiment of the present disclosure, the target candidate cell configuration is the candidate cell configuration that is activated or deactivated when the candidate cell configuration is changed. In an embodiment of the present disclosure, the predefined rules include any of the following: In the first type, it is determined whether to perform connectivity failure detection in the target candidate cell based on network configuration instruction information sent by a network side device.

[0199] The network setting indication information is used to indicate whether the terminal needs to perform connection failure detection in the configured target candidate cell. Here, the method for transmitting the network setting indication information further includes: The candidate cell configuration information may include network configuration instruction information in the change instruction information; The change instruction information may include network setting instruction information, and the change instruction information may be used to instruct the terminal to change the candidate cell setting to be used.

[0200] In the second type, the terminal determines whether it needs to perform connection failure detection in the target candidate cell based on whether the cell type of the target candidate cell belongs to a specified type agreed upon by a protocol.

[0201] Here, the designated type includes at least one of a primary cell PCell, a primary cell and secondary cell PSCell, a special cell SpCell, and a primary cell group MCG.

[0202] If the cell type of the target candidate cell belongs to the specified type agreed in the protocol, the terminal decides to perform connection failure detection in the target candidate cell; otherwise, the terminal decides not to perform connection failure detection in the target candidate cell.

[0203] In the third type, whether to perform connectivity failure detection in the target candidate cell is jointly determined based on the network configuration instruction information sent from the network side device and the protocol agreement.

[0204] The specific embodiment has been described in the above embodiment, so it will not be repeated here.

[0205] Here, the network setting instruction information includes fault setting information, and the fault setting information is information set by the network side device so that the terminal performs connection fault detection and / or recovery from connection fault.

[0206] For example, the fault setting information is transmitted to the MAC CE that transmits the change instruction information for the network setting instruction information.

[0207] In a possible embodiment, the failure configuration information includes, but is not limited to, at least one of: reference signal indication information, which is used to indicate a reference signal designated for the terminal to perform connection failure detection; and a beam identifier, which is used to indicate a beam available for the terminal to perform connection failure recovery.

[0210] Step 3: The terminal performs connection failure detection in the target candidate cell, and after the connection failure is detected, triggers the terminal to perform connection failure recovery in response to the target candidate cell setting being reactivated, or performs connection failure detection in the target candidate cell, and in response to the connection failure being detected, triggers the terminal to perform connection failure recovery in the cell in which the candidate cell setting is activated.

[0211] In an embodiment of the present disclosure, triggering the terminal to recover from a connection failure includes: triggering the terminal to perform random access in the target candidate cell; and triggering the terminal to report information of a connection failure associated with the target candidate cell.

[0212] Here, the information of the connection failure reported by the terminal is a candidate cell configuration identifier corresponding to the connection failure; a candidate cell identifier corresponding to the connection failure; The type of connection failure, cell states corresponding to connection failures; a cell configuration state corresponding to a connection failure; Reference signal information corresponding to a connection failure; Cell information for recovery from connection failures; and reference signal information for recovery from connection failure.

[0214] The types of connection failure include, but are not limited to, at least one of beam failure and physical layer out-of-synchronization.

[0215] Cell states corresponding to a connection failure include, but are not limited to, an activated state and a deactivated state.

[0216] The cell configuration states corresponding to a connection failure include, but are not limited to, an activated state and a deactivated state.

[0217] In an embodiment of the present disclosure, the network side device sets cell states for different candidate cells, including an activated state or a deactivated state, and a candidate cell set in an activated state may actually be in an activated state or a deactivated state. The cell setting state corresponding to a connection failure refers to the cell state set by the network side device for a cell in which a connection failure occurs. The cell state corresponding to a connection failure refers to the actual state of the cell in which a connection failure occurs.

[0218] Here, the reference signal information corresponding to the connection failure includes, but is not limited to, beam information corresponding to the beam failure.

[0221] In the above embodiment, when the configuration of the candidate cell used by the terminal is changed, the terminal may determine whether to perform connection failure detection in the target candidate cell according to a predefined rule, and then perform connection failure detection in the target candidate cell. If a connection failure is detected, the terminal may trigger the terminal to perform connection failure recovery, thereby improving the stability of the wireless connection, ensuring consistent understanding between the network side device and the terminal, and high availability.
