[0071] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0072] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0074] To help understand the solutions of the embodiments of this application, the following will briefly introduce the relevant concepts that may be involved in this application:

[0075] (a) Deactivate SCG

[0076] In multi-connectivity scenarios, there is one Master Cell Group (MCG) and one or more Secondary Cell Groups (SCGs). The Master Node (MN) side's cell group is the Master Cell Group, consisting of one Primary Cell (PCell) and zero to multiple Secondary Cells (SCells). The Secondary Node (SN) side's cell group is the Secondary Cell Group; similarly, an SCG consists of one Primary-Secondary Cell (PSCell) and zero to multiple Secondary Cells (SCells). The current protocol version only supports dual-connectivity scenarios. In connected mode, if the UE is configured with dual connectivity, both the MN and SN can simultaneously interact with the UE.

[0077] To save energy and quickly activate the SCG for data transmission, the UE can set the SCG side to deactivate the SCG when the data transmission volume is small. In the deactivation state, the UE does not monitor the Physical Downlink Control Channel (PDCCH) on the SCG side, nor does it transmit the Physical Uplink Share Channel (PUSCH).

[0078] (II) Activating / Deactivating SCG

[0079] The MN / SN / UE can request SCG activation; network-triggered SCG activation commands are sent from the MN to the UE. The MN / SN can also request SCG deactivation; network-triggered SCG deactivation commands are sent from the MN to the UE. During SCG activation / deactivation, RRC signaling is used for interaction between the UE / MN and the MN / SN.

[0080] When the SCG is deactivated, all Timing Advance Timers (TATs) on the SCG side continue to run. If a TAT times out while the SCG is deactivated, the Random Access Channel (RACH) procedure will not be performed. In the deactivated SCG state, the UE can perform Radio Resource Management (RRM) measurements and can perform Beam Failure Detection (BFD) / Radio Link Monitoring (RLM) based on network configuration. In the deactivated SCG state, all SCG SCells are deactivated.

[0081] Figure 1 This is one of the flowcharts illustrating the SCG status information processing method provided in this application embodiment, such as... Figure 1 As shown in the figure, this application provides a method for processing SCG status information, the execution subject of which is a terminal, and the method includes:

[0082] Step 101: Receive the SCG processing command sent by the network-side device;

[0083] Step 102: Based on the SCG processing instructions, adjust the state of the SCG to the first state and record the state information of the SCG in the first state.

[0084] Specifically, currently, terminal UEs support dual connectivity scenarios, typically consisting of one primary node (MN) and one secondary node (SN). Both MN and SN are connected to the core network (CN). This refers to the terminal UE's operating mode in connected state. When the terminal UE is configured with a primary cell group (MCG) and a secondary cell group (SCG) by the network, it is called dual connectivity (DC). There may be one or more secondary nodes (SN). When the terminal UE connects to multiple secondary nodes (SNs), the current terminal UE is in a multi-connectivity scenario. The MCG contains one or more cells and is the first cell group the UE connects to. The MCG includes a primary cell (PCell) and secondary cells (SCells). Cells in the primary cell group other than the primary cell are called secondary cells. The primary cell is the first cell the terminal UE connects to within the MCG. The SCG contains one or more cells and is a secondary cell group added by the UE after establishing a connection with the MCG. The first cell the terminal connects to within the SCG is called the primary / secondary cell (PSCell). Cells in the secondary cell group other than the PSCell are also called SCells.

[0085] When a terminal is in a multi-connection scenario, the network-side device may send SCG processing commands to the terminal according to service requirements, instructing the terminal to adjust the state of one or more connected SCGs, or to set the state of one or more SCGs to be connected to the first state. This first state could be active, deactivated, idle, connected, etc., adjusted to different states depending on different service requirements. The terminal records relevant information about the state adjustment of each SCG. The specific recorded SCG state adjustment information can include various details, such as: the SCG's previous state, the time spent adjusting the state, and whether beam failure or wireless link failure was detected during the state adjustment process.

[0086] The information related to the SCG status adjustment recorded above can be saved in the form of a new report, or recorded in the existing UE movement history information on the SCG side, or in other existing reports, etc.

[0087] The SCG status information processing method provided in this application embodiment records SCG status-related information in multi-connection scenarios and reports the SCG status-related information to the network side, so that the network side can understand the changes in SCG status, determine whether the SCG side PSCell and the network side uplink and downlink are synchronized, and further assist the network side in optimizing SCG activation or deactivation decisions and related configurations.

[0088] Optionally, adjusting the state of the SCG to the first state based on the SCG processing instructions includes:

[0089] If the SCG processing instruction is an SCG activation instruction, then the SCG state is adjusted to the active state;

[0090] If the SCG processing instruction is an SCG deactivation instruction, then the state of the SCG will be adjusted to the deactivation state.

[0091] Specifically, in a multi-connection scenario, the SCG to which the currently accessed PSCell belongs is active, and there is a one-to-one correspondence between the PSCell and the SCG. The terminal can determine the SCG to which the PSCell belongs based on the currently accessed PSCell. The currently accessed PSCell can be the target PSCell after the terminal switches over; this target PSCell is a PSCell reconfigured by the network side, and the SCG to which this PSCell belongs is active. Alternatively, it can be the source PSCell, i.e., the normally connected PSCell. If the terminal has no service requirements or is considering energy saving, the network side sends an SCG deactivation command to the terminal via the primary node MN or secondary node SN. The terminal receives the command, deactivates the SCG, and records the SCG's status information on the terminal side. This helps the network side understand the SCG status changes, determine whether the PSCell on the SCG side is synchronized with the network's downlink or uplink DL / UL, and further assist the network side in optimizing SCG activation or deactivation decisions and related configurations.

[0092] Similarly, when the SCG to which the terminal's currently accessed PSCell or the PSCell to be accessed belongs is in an inactive state, the aforementioned PSCell to be accessed refers to the target PSCell to which the terminal needs to switch. This target PSCell is a PSCell reconfigured by the network side, and the SCG to which this PSCell belongs is in an inactive state. Because the SCG to which the target PSCell belongs is in an inactive state, the UE will not immediately perform random access to the target PSCell. When the network side has new service requirements for the terminal, and the SCG is in an inactive state, the terminal does not monitor the PDCCH on the SCG side, nor does it transmit PUSCH. Therefore, it is necessary to activate the SCG to which the terminal's currently accessed PSCell belongs as soon as possible, or to activate the SCG to which the PSCell to be accessed belongs as soon as possible, and then randomly access the PSCell to be accessed. This facilitates the rapid recovery or establishment of the data transmission channel, thereby enabling new services or data transmission. Therefore, the network side sends an SCG activation command to the terminal through the primary node MN or the secondary node SN. The terminal receives the command, activates the SCG, and records the SCG's status information on the terminal side.

[0093] There are several ways to record the SCG's state information in its first state. For example, when receiving an SCG activation command, it can record whether the SCG is in an active or deactivated state, and whether beam failure or wireless link failure was detected during the SCG activation process. When receiving an SCG deactivation command, it can record whether the SCG is in an active or deactivated state, and whether beam failure or wireless link failure was detected during the SCG deactivation process.

[0094] The aforementioned SCG activation and deactivation commands can be sent by the primary node MN or secondary node SN in the network device.

[0095] Optionally, the status information of the SCG includes any one or more of the following:

[0096] SCG's PSCell logo;

[0097] First indication information used to indicate that the SCG is in a first state;

[0098] The number of times SCG is in the first state;

[0099] Information on when SCG is in its first state;

[0100] The second indication information is used to indicate whether the advance timer TAT has timed out;

[0101] The third indication information is used to indicate whether a beam failure has been detected.

[0102] The fourth indication information is used to indicate whether a wireless link failure has been detected;

[0103] The first state is either an active state or a deactivated state.

[0104] Specifically, the terminal can record the SCG status information using any one or a combination of the following methods:

[0105] 1. SCG PSCell identifier, i.e., the PSCell identifier currently accessed by the terminal or the PSCell identifier information to be accessed.

[0106] In a multi-connection scenario, the terminal connects to a PSCell, and the SCG to which the PSCell belongs is in an active state. When the terminal has no service requirements or to save energy, the network side will send an SCG deactivation command. During the deactivation process, the terminal records the identifier of the currently accessed PSCell or the identifier of the PSCell to be accessed. There is a one-to-one correspondence between PSCell identifiers and SCGs. Deactivating a PSCell means setting the SCG to which the PSCell belongs to a deactivated state. For a normal SCG deactivation command, that is, a deactivation command without a synchronization reconfiguration command, the UE records the ID of the currently accessed PSCell. For an SCG deactivation command sent to the UE along with a synchronization reconfiguration command, that is, when the SCG to which the target PSCell belongs is configured to a deactivated state, the UE may record either the source PSCell ID or the target PSCell ID. For example, if the synchronization reconfiguration command indicates that the SCG state is in a deactivated state, the target PSCell ID may be recorded.

[0107] When a terminal connects to or is about to access a PSCell, and the SCG to which that PSCell belongs is in an inactive state, and there is a need for new services or data transmission, the network side sends an SCG activation command. During the activation process, the terminal records the identifier of the currently accessed PSCell. There is a one-to-one correspondence between the PSCell identifier and the SCG. Activating the PSCell sets the SCG to which that PSCell belongs to the active state. For ordinary SCG activation commands, which are not sent together with the synchronization reconfiguration command, the terminal needs to determine whether the network side has reconfigured the target PSCell to which the terminal needs to switch before receiving the SCG activation command, and whether the SCG to which the target PSCell belongs is in an inactive state. If the network previously reconfigured the target PSCell, and the SCG to which the target PSCell belongs is in an inactive state, then upon receiving the SCG activation command, the target PSCell will be activated, and its identifier will be recorded. If the network previously did not reconfigure the target PSCell, and the SCG to which the target PSCell belongs is in an inactive state, then upon receiving the SCG activation command, the SCG to which the currently accessed PSCell belongs will be activated, effectively setting the SCG to which the currently accessed PSCell belongs to the active state. If the SCG activation command and the synchronization reconfiguration command are sent together, and the synchronization reconfiguration command configures the target PSCell, then the terminal will access the target PSCell, and its identifier will be recorded.

[0108] The aforementioned PSCell identifier can be represented in the form of PSCell ID, which can be represented by the Physical Cell Identifier (PCI) and frequency point, or the Cell Global Identifier (CGI).

[0109] 2. First indication information used to indicate that the SCG is in a first state.

[0110] An indication message indicates whether the SCG to which the PSCell to which the terminal is connected is in an inactive or active state, or whether the SCG to which the PSCell to which the terminal is to be connected is in an inactive state. This can be recorded in different forms, such as in the form of an entry. In one entry, the SCG state is indicated to be in an inactive state. This entry is used to record information related to the SCG deactivation process.

[0111] 3. The number of times the SCG is in the first state, that is, the number of times the SCG of the PSCell currently connected to the terminal or the PSCell to be connected is in an active state, or the number of times it is in a deactivated state.

[0112] Record the number of times the SCG state of the PSCell to which the terminal belongs changes to the deactivated state while the terminal maintains the connection to the currently accessed PSCell after receiving an SCG deactivation command, or while maintaining the connection to the PSCell to which it needs to be accessed after determining the PSCell to be accessed; or the number of times the SCG state of the currently accessed PSCell to the active state while the terminal maintains the connection to the currently accessed PSCell after receiving an SCG activation command. The currently accessed PSCell can be the target PSCell after the terminal switches over, which is a PSCell reconfigured by the network side and whose SCG state is active, or it can be the source PSCell, i.e., the PSCell that is normally connected.

[0113] 4. The time information of the SCG in the first state, that is, the time information of the SCG to which the PSCell currently accessed or the PSCell to be accessed by the terminal belongs is in a specific state; wherein, the specific state is an active state or a deactivated state.

[0114] The system records the specific time information when the terminal receives an SCG deactivation command, indicating that the SCG to which the currently connected PSCell or the PSCell to be connected belongs is in an inactive state; or when the terminal receives an SCG activation command, indicating that the SCG to which the currently connected PSCell belongs is in an active state. The currently connected PSCell can be the target PSCell after the terminal switches over, which is a PSCell reconfigured by the network side, and the SCG to which this PSCell belongs is in an active state; or it can be the source PSCell, i.e., a normally connected PSCell.

[0115] 5. Second indication information, used to indicate whether the advance timer TAT has timed out, that is, whether TAT has timed out each time the SCG is activated, or each time the SCG is in the deactivation state.

[0116] Record whether the TAT corresponding to the SCG to which the PSCell to which the terminal is connected or to be connected is timed out during each deactivation process when the terminal receives the SCG deactivation instruction; or whether the TAT corresponding to the SCG to which the PSCell to which the terminal is connected is timed out each time the terminal receives the SCG activation instruction.

[0117] 6. The third indication information is used to indicate whether beam failure is detected, that is, whether beam failure is detected each time the SCG is activated, or each time the SCG is in the deactivation state.

[0118] Record whether, when the terminal receives an SCG deactivation command, the SCG belonging to the PSCell to which the terminal is connected or to be connected detects beam failure each time it is in the deactivation state; or whether, when the terminal receives an SCG activation command, the SCG belonging to the PSCell to which the terminal is connected detects beam failure each time it is activated.

[0119] 7. Fourth indication information, used to indicate whether a radio link failure is detected, that is, whether a radio link failure (RLF) is detected each time the SCG is activated, or each time the SCG is in a deactivation state.

[0120] Record whether the SCG to which the PSCell to which the terminal is connected detects a Radio Link Failure (RLF) each time it is in the deactivation state when the terminal receives an SCG deactivation command; or whether the SCG to which the PSCell to which the terminal is connected detects a Radio Link Failure (RLF) each time it is activated when the terminal receives an SCG activation command.

[0121] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0122] Optionally, the status information of the SCG includes any one or more of the following:

[0123] Status information used to indicate the status of the SCG to which the terminal belongs when it first accesses the SCG;

[0124] Used to indicate that the SCG was previously in a first state;

[0125] The total duration for which SCG maintains the first state.

[0126] Specifically, the SCG status information recorded by the terminal includes any one or more of the following:

[0127] An indication message indicates the state of the SCG when the terminal first accesses the SCG, that is, when the terminal accesses or is waiting to access a PSCell, the state of the SCG to which the PSCell belongs is either deactivated or activated when it first accesses the PSCell; the state of the SCG may be different from or the same as the first state after the received processing instruction adjusts the state of the SCG. This is mainly because when the terminal receives an SCG deactivation command, if the SCG deactivation command is sent to the UE along with a synchronization reconfiguration command, the UE can record the target PSCell ID configured in the synchronization reconfiguration command and record the SCG state when accessing this PSCell as SCG deactivated. For example, it can indicate that the SCG state when accessing this PSCell is SCG deactivated. When the terminal receives an SCG activation command, if the SCG activation command is sent to the UE along with a synchronization reconfiguration command, the UE can record the target PSCell ID configured in the synchronization reconfiguration command and record the SCG state when accessing this PSCell as SCG activated. For example, it can indicate that the SCG state when accessing this PSCell is SCG activated. The PSCell that the terminal wants to access mainly refers to the target PSCell configured through the synchronization reconfiguration command.

[0128] An indication message indicates that the SCG was previously in a first state, meaning that during the terminal's access to the PSCell, the SCG belonging to that PSCell was either in an inactive or active state. When the terminal receives an SCG deactivation instruction, if the SCG belonging to that PSCell was previously in an inactive state during the UE's access to a PSCell, regardless of how many times the SCG changed to an inactive state during this process, only one indication message needs to be recorded indicating that the SCG was deactivated. For example, if this indication is true, it means that the SCG belonging to that PSCell was previously in an inactive state during the access to this PSCell. Similarly, when the terminal receives an SCG activation instruction, meaning that during the UE's access to a PSCell, if the SCG belonging to that PSCell was previously in an active state, regardless of how many times the SCG changed to an active state during this process, only one indication message needs to be recorded indicating that the SCG was activated. For example, if this indication is true, it means that the SCG was activated during the access to this PSCell.

[0129] The total duration for which the SCG remains in the first state is the total duration for which the SCG of the PSCell currently accessed by the terminal remains in an active or deactivated state, or the total duration for which the SCG of the PSCell to which the terminal is about to access remains in a deactivated state. Specifically, when the terminal receives an SCG deactivation command, the total duration for which the SCG of the PSCell to which the terminal belongs is in a deactivated state during the connection process or while the terminal is about to access a PSCell is such that, for example, if the SCG of the PSCell to which the UE belongs is in a deactivated state three times during the connection process, with durations of 1ms, 2ms, and 1ms respectively, then the total duration for which the SCG of the PSCell to which the terminal belongs is in a deactivated state is 4ms. When the terminal receives an SCG activation command, the total duration for which the SCG of the PSCell to which the terminal belongs is in an active state during the connection process of the terminal is such that, for example, if the SCG of the PSCell to which the UE belongs is in an active state twice during the connection process, with durations of 1.5ms and 2ms respectively, then the total duration for which the SCG of the PSCell to which the terminal belongs is in an active state is 3.5ms.

[0130] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0131] Optionally, the time information includes any one or more of the following:

[0132] The duration for which SCG maintains the first state;

[0133] SCG maintains the start and end times of the first state.

[0134] Specifically, the terminal will also record the time information of the SCG to which the PSCell currently connected to the terminal or the PSCell to be connected belongs is in the first state, including any one or more of the following:

[0135] The duration for which the SCG maintains the first state is the duration for which the SCG remains in an active or deactivated state each time. When the terminal receives an SCG deactivation command, the duration for which the SCG remains in the deactivated state each time, for example, during this PSCell access process, there are 5 instances of being in the deactivated state with durations of 1ms, 0.5ms, 0.3ms, 0.6ms, and 2ms, which can be recorded in the entry for each deactivated SCG. When the terminal receives an SCG activation command, the duration for which the SCG remains in the active state each time, for example, during this PSCell access process, there are 2 instances of being in the active state with durations of 1ms and 2ms, which can be recorded in the entry for each activated SCG.

[0136] The SCG maintains the start and end times of the first state, that is, the start and end times of each active or deactivated state of the SCG, including absolute and relative times. That is, it can record the UTC time or the time since the UE first accessed this PSCell. For example, if there are 5 times in the deactivated state, the corresponding start and end times are {1ms, 2ms}, {5ms, 5.5ms}, {8ms, 8.3ms}, {11ms, 11.6ms}, and {16ms, 18ms}, that is, record the relative time, which can be recorded in the entry of each deactivated SCG; or if there are 2 times in the active state, the corresponding start and end times are {1ms, 2ms} and {5ms, 7ms}, that is, record the relative time, which can be recorded in the entry of each active SCG.

[0137] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0138] Optionally, if the third indication information indicates that a beam failure has been detected, the SCG status information may further include:

[0139] The beam identifier and beam measurement results for beam failure were detected.

[0140] Specifically, when the terminal receives the SCG deactivation command sent by the network side, during each time the SCG is in the deactivation state, or when it receives the activation command sent by the network side and a beam failure is detected each time the SCG is activated, it also needs to record the beam-related information of the beam failure, including the beam identifier and beam measurement result of each detected beam failure. If there are multiple beam failures during this deactivation process, the beam identifier and beam measurement result of each beam failure can be recorded in a list.

[0141] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0142] Optionally, if the first state is a deactivated state and the third indication information indicates that a beam failure has been detected, the SCG's state information may further include any one or more of the following:

[0143] Number of beam failure recovery attempts;

[0144] The fifth indication information used to indicate whether beam failure recovery was successful;

[0145] If the fifth indication indicates that the beam failure recovery is successful, then record the beam identifier and beam measurement result for each successful beam failure recovery;

[0146] The number of times beam failure occurred.

[0147] Specifically, when the terminal receives an SCG deactivation command, during the SCG deactivation process, each time a beam failure is detected, the terminal records an indication of whether the beam failure was successfully recovered. For example, a true indication indicates successful recovery, while a false indication indicates unsuccessful recovery. This information can be recorded in a list. The number of beam failure recoveries can also be recorded, also in a list. Furthermore, if the indication indicates successful recovery for one or more beam failures, the corresponding record shows the recovered beam identifier and beam measurement results for each successful recovery. In the case of multiple successful recoveries, the beam identifier and beam measurement results for each successful recovery can be recorded in a list.

[0148] In addition, the number of beam failures during each SCG deactivation process can be recorded. When the terminal receives an SCG deactivation command, during the SCG deactivation process, the terminal will record the number of beam failures that occurred each time a beam failure is detected. For example, if the number of beam failures during this deactivation process is 3, then the number of records for beam identifiers and beam measurement results for each detected beam failure will be the same as the recorded number of beam failures.

[0149] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0150] Optionally, if the first state is a deactivated state, and the fourth indication information indicates that a wireless link failure has been detected, then the SCG's state information may further include any one or more of the following:

[0151] Reasons for wireless link failure;

[0152] Number of times the wireless link failed to recover;

[0153] The sixth indication information used to indicate whether the wireless link failure recovery was successful;

[0154] The number of times a wireless link failure occurred.

[0155] Specifically, when the terminal receives the SCG deactivation command, if the terminal detects a wireless link failure during the SCG deactivation process, it also needs to record relevant information about the wireless link failure, including one or more of the following:

[0156] The reasons for wireless link failure, such as: the reason for this wireless link failure is T310 timeout, and during the SCG deactivation process, there may be multiple wireless link failures. The reasons for each wireless link failure are recorded in a list.

[0157] The number of times wireless link failure recovery was performed, for example: how many times wireless link failure recovery was performed when a wireless link failure was detected, regardless of whether it was successful or not.

[0158] The sixth indication information is used to indicate whether the wireless link failure recovery was successful. That is, the indication information for each wireless link failure recovery is successful. For example, if the indication information for this wireless link failure recovery is true, it means that the wireless link failure recovery was successful. If the indication information for this wireless link failure recovery is false, it means that the wireless link failure recovery failed (unsuccessful). In this SCG deactivation process, there may be multiple wireless link failures. The indication information for the success or failure of multiple wireless link failure recovery is recorded in the form of a list.

[0159] The number of wireless link failures refers to how many times the terminal experiences wireless link failures during the SCG deactivation process after receiving the SCG deactivation command.

[0160] Specifically, when the terminal receives the SCG deactivation command, if the terminal detects a wireless link failure during the SCG deactivation process, it also needs to record relevant information about the wireless link failure, including:

[0161] The number of radio link failures that occurred during each SCG deactivation process is recorded. For example, if the number of radio link failures during this deactivation process is 2, then the corresponding number of records for the reason for each radio link failure will be the same.

[0162] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0163] Optionally, if the first state is an active state, the state information of the SCG may further include any one or more of the following:

[0164] The activation method used when the SCG is activated includes: random access channel RACH method or no random access channel RACH procedure method;

[0165] The seventh indication message used to indicate that TAT is running and its status is invalid;

[0166] The eighth indication information used to indicate whether the Transmission Configuration Indication (TCI) state has been configured on the network side;

[0167] If the eighth indication information indicates that the network side has configured a TCI state, then the SCG state information further includes:

[0168] The value of the TCI state configured on the network side.

[0169] Specifically, when the terminal receives the SCG activation command, i.e., the first state is active, the SCG status information also includes any one or more of the following:

[0170] The activation method used when activating the SCG includes: Random Access Channel (RACH) or RACH-less mode (i.e., no random access channel). For example, if the network side is configured to instruct the terminal to use RACH, the terminal will use RACH for access. If the network side is not configured to instruct the terminal to use RACH, the terminal will determine whether its own conditions meet the conditions for RACH-less access, such as whether the TAT has timed out or failed, whether beam failure has been detected, or whether radio link failure has been detected. If the terminal meets the above conditions, that is, the TAT has not timed out or failed, and beam failure and radio link failure have not been detected, then RACH-less access will be used. If the terminal does not meet the conditions for RACH-less access, then RACH will be used for access.

[0171] This is an indication message used to indicate that TAT is running but invalid. The network side can use this indication message to know that when the terminal UE receives the SCG activation command and activates the corresponding SCG, although TAT is running, the terminal and the network have lost uplink synchronization at this time.

[0172] Indication information used to indicate whether the network side has configured the Transmission Configuration Indication (TCI) state. For example, if this indication is true, it means that the network has configured the TCI state in the SCG activation command when the SCG is activated.

[0173] When the terminal receives the SCG activation command and the network side is configured with TCI state, the SCG state information recorded by the terminal also includes:

[0174] The value of the TCI state configured on the network side when activating the SCG is recorded. Upon receiving the TCI state value configured at that time, along with other auxiliary information related to SCG activation, the network side can determine whether the configured TCI state value was appropriate.

[0175] The above SCG status information includes the recorded content of the active state and the recorded content of the deactivated state. It can be recorded in the same report or in two separate reports.

[0176] After the terminal records the SCG status information, it can report the availability indication to the network side. The network then obtains the SCG status information recorded by the terminal through the UE information process. For example, the UE reports the availability indication to the MN or SN. The MN or SN requests the UE to report the recorded SCG status information through a UEInformationRequest message; the terminal UE reports the recorded SCG status information to the MN or SN through a UEInformationResponse message; when the MN or SN receives the SCG status information sent by the terminal UE, it understands the SCG status change, determines whether the SCG-side PSCell is synchronized with the network downlink (DL) or uplink (UL), and can further optimize the SCG activation or deactivation decision and related configurations.

[0177] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0178] Figure 2 This is a second flowchart illustrating the method for processing SCG status information provided in this application embodiment, as shown below. Figure 2 As shown, the method includes:

[0179] Step 201: Receive the status information of the SCG being in the first state sent by the terminal, wherein the status information of the SCG being in the first state is recorded by the terminal after receiving the SCG processing instruction sent by the network-side device;

[0180] Step 202: Based on the state information of the SCG in the first state, determine the synchronization state of the PSCell in the SCG with the network, and optimize the configuration for activating or deactivating the SCG.

[0181] The first state is either an active state or a deactivated state.

[0182] Specifically, the current terminal UE supports multi-connection scenarios. This means the terminal can connect to one MCG and simultaneously connect to multiple SCGs. An MCG contains one or more cells and is the first cell group the UE connects to. An MCG includes a primary cell (PCell) and secondary cells (SCells). Cells in the primary cell group other than the primary cell are called secondary cells. The primary cell is the first cell the terminal UE connects to within the MCG. An SCG contains one or more cells and is a secondary cell group (SCG) added by the UE after establishing a connection with the MCG. The first cell the terminal connects to within the SCG is called the primary / secondary cell (PSCell). Cells in the secondary cell group other than the PSCell are also called SCells.

[0183] When a terminal is in a multi-connection scenario, the network-side device may send SCG processing instructions to the terminal according to service requirements, so that the terminal can adjust the state of one or more connected SCGs, or set the state of one or more SCGs to be connected to the first state. The first state includes an active state or a deactivated state, and is adjusted to different states according to different service requirements. The terminal records and reports the relevant information on the state adjustment of each SCG.

[0184] When a terminal is in a multi-connection scenario, the SCG to which the currently accessed PSCell belongs is in an active state, and there is a one-to-one correspondence between the PSCell and the SCG. The terminal can determine the SCG to which the PSCell belongs based on the currently accessed PSCell. The currently accessed PSCell can be the target PSCell after the terminal switches over; this target PSCell is a PSCell reconfigured by the network side, and the SCG to which this PSCell belongs is in an active state. Alternatively, it can be the source PSCell, i.e., the normally connected PSCell. If the terminal has no service requirements or is considering energy saving, the network side sends an SCG deactivation command to the terminal through the primary node MN or secondary node SN. The terminal receives the command, deactivates the SCG, and records the SCG's state information on the terminal side, i.e., the terminal records its deactivated state information. This helps the network side understand SCG state changes, determine whether the PSCell on the SCG side is synchronized with the network's downlink or uplink DL / UL, and further assist the network side in optimizing SCG activation or deactivation decisions and related configurations.

[0185] Similarly, when the SCG to which the terminal's currently accessed PSCell or the PSCell to be accessed belongs is in an inactive state, the aforementioned PSCell to be accessed refers to the target PSCell to which the terminal needs to switch. This target PSCell is a PSCell reconfigured by the network side, and the SCG to which this PSCell belongs is in an inactive state. Because the SCG to which the target PSCell belongs is in an inactive state, the UE will not immediately perform random access to the target PSCell. When the network side has new service requirements for the terminal, and the SCG is in an inactive state, the terminal does not monitor the PDCCH on the SCG side, nor does it transmit PUSCH. Therefore, it is necessary to activate the SCG to which the terminal's currently accessed PSCell belongs as soon as possible, or to activate the SCG to which the PSCell to be accessed belongs as soon as possible, and then randomly access the PSCell to be accessed. This facilitates the rapid recovery or establishment of the data transmission channel, thereby enabling new services or data transmission. Therefore, the network side sends an SCG activation command to the terminal through the primary node MN or the secondary node SN. The terminal receives the command, activates the SCG, and records the SCG's status information on the terminal side. That is, the terminal records its active state information.

[0186] The terminal records its state information in a first state, which includes either an active or deactivated state. The specific methods for recording the SCG's first state information can vary. For example, upon receiving an SCG activation command, it records whether the SCG is in an active or deactivated state, and whether beam failure or wireless link failure was detected during the SCG activation process. Similarly, upon receiving an SCG deactivation command, it records whether the SCG is in an active or deactivated state, and whether beam failure or wireless link failure was detected during the SCG deactivation process.

[0187] The SCG status information recorded above, indicating it is in the first state, can be saved in a new report, recorded in the existing UE mobility history information on the SCG side, or recorded in other existing reports. Network devices can send the aforementioned SCG activation and deactivation commands to the terminal via the primary node MN or secondary node SN.

[0188] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0189] Optionally, the optimized configuration for activating or deactivating the SCG includes:

[0190] If the network-side device is the master node MN, then the MN directly performs analysis and optimization, or the MN sends all or part of the received state information of the record SCG in the first state to the auxiliary node SN through the X2 or Xn interface, and the SN performs analysis and optimization, or the MN and SN jointly perform analysis and optimization.

[0191] If the network-side device is a secondary node (SN), then the SN is directly analyzed and optimized.

[0192] Specifically, in a multi-connection scenario, after a terminal records the SCG status information, it can report the SCG status information to the master node MN. The MN then sends the received information, either completely or partially, to the slave node SN through the X2 or Xn interface. The SN then performs analysis and optimization, or the MN and SN perform analysis and optimization together.

[0193] Alternatively, the recorded SCG status information can be directly sent to the SN for analysis and optimization.

[0194] Alternatively, the recorded SCG status information can be directly sent to the MN for analysis and optimization.

[0195] The method for processing SCG state information provided in this application, in a multi-connection scenario, records specific information related to the SCG in the active or deactivated state and reports the specific information related to the SCG state to the network side. This makes it easier for the network side to understand the changes in the SCG state more clearly, accurately determine whether the uplink and downlink of the SCG-side PSCell and the network side are synchronized, and further assist the network side in optimizing the SCG activation or deactivation decision and related configuration.

[0196] The following example illustrates the method for processing SCG status information provided in this application.

[0197] Example 1: When a terminal UE connects to a PSCell and the SCG to which the PSCell belongs is in an active state, it receives an SCG deactivation command.

[0198] Step 1: The UE is in a PSCell and the SCG activation state is SCG active.

[0199] Step 1a: The UE is not currently configured with SCG;

[0200] Step 2: The UE receives the SCG deactivation command sent by the MN;

[0201] Step 2a: The UE receives the PSCell addition command sent by the MN, in which the SCG activation state is indicated as deactivated;

[0202] Step 3: The UE deactivates the SCG and records one or more of the following:

[0203] Step 3a: The UE records one or more of the following, or the UE does not record any content before activating SCG:

[0204] To deactivate the SCG PSCell ID, for a regular SCG deactivation command (i.e., without a synchronization reconfiguration command), the UE records the currently accessed PSCell ID. For an SCG deactivation command sent to the UE along with a synchronization reconfiguration command (i.e., the target PSCell is configured to be in an SCG deactivated state), the UE may record either the source PSCell ID or the target PSCell ID. For example, if the synchronization reconfiguration command indicates that the SCG activation state is in an SCG deactivated state, the target PSCell ID is recorded.

[0205] An indication message indicates that the SCG state is deactivated. That is, the SCG state recorded in this entry can be recorded as SCG deactivated. For example, in an entry, the SCG activation state is indicated as SCG deactivated. This entry is used to record information related to this SCG deactivation process.

[0206] An indication message indicates that the SCG activation state when accessing this PSCell is SCG deactivation state. This is mainly because if the SCG deactivation command is sent to the UE along with the synchronization reconfiguration command, the UE can record the target PSCell ID and record that the SCG activation state when accessing this PSCell is SCG deactivation state. For example, it indicates that the SCG activation state when accessing this PSCell is SCG deactivation state.

[0207] An indication message indicates that the SCG was deactivated during the access to this PSCell, meaning that the SCG was once in a deactivated state. In other words, if the SCG to which the PSCell belongs was in a deactivated state during the UE's access to a PSCell, regardless of how many times the SCG changed to a deactivated state, only one indication message needs to be recorded to indicate that the SCG was deactivated. For example, if this indication is true, it means that the SCG was deactivated during the access to this PSCell.

[0208] The number of times the SCG is deactivated in this PSCell indicates how many times the SCG has been deactivated during the UE's access to this PSCell. For example, the SCG was deactivated 5 times during the access to this PSCell.

[0209] The duration of each SCG in the deactivated state indicates the duration of the SCG in the deactivated state each time it is deactivated. For example, in this PSCell access process, the durations of these 5 deactivations are 1ms, 0.5ms, 0.3ms, 0.6ms, and 2ms, respectively, which can be recorded in the entry of each deactivated SCG.

[0210] The start and end times of each SCG deactivation, including absolute and relative times, can be recorded as either UTC time or the time since the UE first accessed this PSCell. For example, the start and end times of these 5 deactivations are {1ms, 2ms}, {5ms, 5.5ms}, {8ms, 8.3ms}, {11ms, 11.6ms}, and {16ms, 18ms}, respectively, which are relative times. These can be recorded in the entry of each SCG deactivation.

[0211] The total duration of SCG in the deactivated state in this PSCell is the total duration of all SCGs in the deactivated state while the UE is in this PSCell. For example, the total duration of all SCGs in the deactivated state while the UE is in this PSCell is 4.4ms.

[0212] An indicator that indicates whether the TAT has timed out during each deactivation process. For example, if this indicator is true, it means that the TAT has timed out during this deactivation process.

[0213] An indicator that indicates whether beam failure was detected during each deactivation process. For example, if this indicator is true, it means that a beam failure was detected during this deactivation process.

[0214] Beam-related information for beam failures includes beam ID and beam measurement results. That is, if a beam failure is detected during this deactivation process, the failed beam ID and beam measurement results are recorded. If multiple beam failures occur during this deactivation process, multiple sets of beam information can be recorded in a list.

[0215] The number of times beam failure recovery occurred; how many times beam failure recovery was performed after a beam failure was detected.

[0216] An indication message indicates whether the beam failure has been recovered. That is, if a beam failure is detected during this deactivation process, then indicate whether the beam failure has been recovered. For example, if this indication is true, it means that the beam failure has been recovered. Multiple indication messages can be recorded in a list.

[0217] The recovered beam-related information includes beam ID and beam measurement result information. That is, if the beam failure is recovered, the recovered beam ID and beam measurement result information are recorded. Multiple sets of recovered beam information can be recorded in a list.

[0218] The number of beam failures that occur during a single deactivation process, i.e., the number of times a beam failure occurs during this deactivation process. For example, the number of beam failures that occur during this deactivation process is 3.

[0219] An indicator that indicates whether a Radio Link Failure (RLF) is detected during each deactivation process. For example, if this indicator is true, it means that an RLF was detected during this deactivation process.

[0220] The reason for this RLF, for example: the reason for this RLF is T310 timeout, can be recorded in a list to record the reasons for multiple RLFs;

[0221] An indicator that indicates whether the RLF has been recovered. For example, if this indicator is true, it means that the RLF has been recovered. Multiple RLF recovery statuses can be recorded in a list.

[0222] The number of wireless link failure recovery attempts is recorded, specifically how many times wireless link failure recovery was performed during the deactivation process when a wireless link failure was detected.

[0223] The number of times an RLF occurs during a single deactivation process, i.e., the number of times an RLF occurs during this deactivation process, for example: the number of times an RLF occurs during this deactivation process is 1;

[0224] Step 4: The UE reports the indication it can obtain to the MN / SN;

[0225] Step 5: The MN / SN requests the UE to report the SCG activation status information recorded in the UE InformationRequest message;

[0226] Step 6: The UE reports the recorded SCG activation status information to the MN / SN via the UEInformationResponse message;

[0227] Step 7: When the MN / SN receives the SCG activation status information sent by the UE, the MN / SN understands the changes in the SCG status, determines whether the SCG-side PSCell is synchronized with the network DL / UL, and can further optimize the SCG activation / deactivation decision and related configurations.

[0228] Example 2: When a terminal UE connects to a PSCell and the SCG to which the PSCell belongs is in a deactivated state, it receives an SCG activation command.

[0229] Step 1: The UE is in a PSCell, and the SCG activation state is SCG deactivation state;

[0230] Step 1a: The UE is not configured with SCG;

[0231] Step 2: The UE receives the SCG activation command sent by the MN;

[0232] Step 2a: The UE receives the PSCell addition command sent by the MN, in which the SCG activation state is indicated as active;

[0233] Step 3: The UE activates the SCG and records one or more of the following:

[0234] Step 3a: The UE randomly accesses the target PSCell and records one or more of the following:

[0235] To activate the PSCell ID of an SCG, for a normal SCG activation, if the SCG activation command is not sent along with the synchronization reconfiguration command, the terminal needs to determine whether the network side reconfigured the target PSCell to which the terminal needs to switch before receiving the SCG activation command, and whether the SCG to which the target PSCell belongs is inactive. If the network side reconfigured the target PSCell beforehand, and the SCG to which the target PSCell belongs is inactive, then upon receiving the SCG activation command, the target PSCell is activated, and its identifier is recorded. If the network side did not reconfigure the target PSCell beforehand, and the SCG to which the target PSCell belongs is inactive, then upon receiving the SCG activation command, the SCG to which the terminal is currently connected to is activated, i.e., the SCG to which the terminal is currently connected to is set to active. If the SCG activation command is sent along with the synchronization reconfiguration command, and the synchronization reconfiguration command configures the target PSCell, then the terminal connects to the target PSCell and its identifier is recorded.

[0236] An indication message indicates that the SCG state is active. This means that the SCG state recorded in an entry can be recorded as SCG active. For example, an entry indicates that the SCG activation state is SCG active. This entry is used to record information related to this SCG activation process.

[0237] An indication message indicates that the SCG activation state is SCG active when accessing this PSCell. This is mainly because if the SCG activation command is sent to the UE along with the synchronization reconfiguration command, the UE can record the target PSCell ID and record that the SCG activation state is SCG active when accessing this PSCell. For example, it indicates that the SCG activation state is SCG active when accessing this PSCell.

[0238] An indication message indicates that the SCG was activated during the access to this PSCell, that is, the SCG was once in an active state. In other words, if the SCG to which the PSCell belongs was once active during the access of the UE to a PSCell, regardless of how many times the SCG changed to an active state, only one indication message is recorded to indicate that the SCG was activated. For example, if this indication is true, it means that the SCG was activated during the access to this PSCell.

[0239] The number of times the SCG is activated in this PSCell indicates how many times the SCG has been activated during the UE's access to this PSCell. For example, the SCG was activated twice during the access to this PSCell.

[0240] The duration of each SCG in the active state indicates the duration of the SCG in the active state each time it is activated. For example, in this PSCell access process, the durations of these two activations are 1ms and 2ms respectively, which can be recorded in the entry of each activated SCG.

[0241] The start and end times of each SCG activation include absolute and relative times. This can be recorded as either UTC time or the time elapsed since the UE first accessed the PSCell. For example, the start and end times of these two activations are {1ms, 2ms} and {5ms, 7ms}, respectively, which are relative times. These can be recorded in the entry for each activated SCG.

[0242] The total duration of SCG in the active state in this PSCell is the total duration of all SCG active states while the UE is in this PSCell. For example, the total duration of all SCG active states while the UE is in this PSCell is 3ms.

[0243] An indication message indicating whether TAT is running when SCG is activated. For example, if this indication is true, it means that TAT timed out when SCG was activated.

[0244] An indication message indicating whether a beam failure occurred during SCG activation. For example, if this indication is true, it means that a beam failure occurred when the SCG was activated.

[0245] Beam information where a beam failure occurs, such as beam ID and beam measurement result information. That is, if a beam failure is detected when SCG is activated, the UE records the beam ID and beam measurement result information of the failure.

[0246] An indication message indicating whether an RLF occurred when the SCG was activated. For example, if this indication is true, it means that a radio link failure (RLF) occurred when the SCG was activated.

[0247] When activating the SCG, is the activation method either RACH or RACH-less? For example, the UE uses the RACH method to activate the SCG.

[0248] A message indicating that TAT is running but is ineffective;

[0249] Does the network have a TCI state configured when the SCG is activated? For example, if this indicator is true, it means that the network has a TCI state configured when the SCG is activated.

[0250] The TCI state configured by the network when SCG is activated, i.e., the TCI state value configured by the network recorded by the UE;

[0251] Step 4: The UE reports the indication it can obtain to the MN / SN;

[0252] Step 5: The MN / SN requests the UE to report the SCG activation status information recorded in the UE InformationRequest message;

[0253] Step 6: The UE reports the recorded SCG activation status information to the MN / SN via the UEInformationResponse message;

[0254] Step 7: When the MN / SN receives the SCG activation status information sent by the UE, the MN / SN understands the changes in the SCG status, determines whether the PSCell on the SCG side is synchronized with the network DL / UL, and can further optimize the relevant configurations for activating / deactivating the SCG.
