The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

In order to help understand the solutions of the embodiments of the present disclosure, the following will briefly introduce related concepts that may be involved in the present disclosure:

(1) Deactivation of SCG

In the multi-connection scenario, it is divided into a master cell group (Master Cell Group, MCG) and one or more secondary cell groups (Secondary Cell Group, SCG). The cell group on the master node (MasterNode, MN) side is the master cell group, consisting of one primary cell (Primary Cell, PCell) and zero to multiple secondary cells (Secondary Cell, SCell). The cell group on the secondary node (SecondaryNode, SN) side is a secondary cell group, and an SCG is also composed of a primary secondary cell (Primary Secondary Cell, PSCell) and zero to multiple secondary cells SCell. The current protocol version only supports dual connection scenarios. In the connected state, the UE is configured with dual connectivity, and the MN and SN can exchange data with the UE at the same time.

In consideration of energy saving and fast activation of SCG for data transmission, the UE can set the SCG side to the deactivated SCG state when the amount of data transmission is small. In the deactivated SCG state, the UE does not perform SCG side physical downlink control channel Control Channel, PDCCH) monitoring, without performing physical uplink shared channel (Physical Uplink Share Channel, PUSCH) transmission.

(2) Activation/deactivation of SCG

The MN/SN/UE may request to activate the SCG, and the SCG activation command triggered by the network is sent by the MN to the UE. The MN/SN may request to deactivate the SCG, and the SCG deactivation command triggered by the network is sent by the MN to the UE. During the SCG activation/deactivation process, RRC signaling is used for interaction between UE/MN and MN/SN.

When the SCG is deactivated, all timing advance timers (Timing Advance Timer, TAT) on the SCG side continue to run. In the deactivated state of the SCG, if the TAT times out, the random access channel (Random Access Channel, RACH) process will not be performed. In the SCG deactivated 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.

Fig. 1 is one of the schematic flowcharts of the method for processing SCG state information provided by the embodiment of the present disclosure. As shown in Fig. 1 , the embodiment of the present disclosure provides a method for processing SCG state information, the execution subject of which is a terminal, and the method includes :

Step 101, receiving the SCG processing instruction sent by the network side device;

Step 102: Adjust the state of the SCG to the first state based on the SCG processing instruction, and record state information that the SCG is in the first state.

Specifically, currently, a terminal UE supports a dual-connection scenario, generally a primary node MN and a secondary node SN, and both MN and SN are connected to the core network (Core Network, CN), that is, the operation mode of the terminal UE in the 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 (Dual Connectivity, DC), and there may be one or more secondary nodes SN, the corresponding terminal When the UE is connected to multiple secondary nodes SN, the current terminal UE is in a multi-connection scenario. MCG contains one or more cells, which is the first cell group connected to UE; MCG includes primary cell PCell and secondary cell SCell, all cells in the primary cell group except the primary cell are called secondary cells, and the primary cell is the terminal UE The first cell connected in the MCG. SCG contains one or more cells, which is the secondary cell group SCG added after the UE establishes a connection with the MCG. The first cell connected to the terminal in all cells in the SCG is called the primary and secondary cells. Cell PSCell. The cells other than the PSCell in the secondary cell group are also called SCells.

When the terminal is in a multi-connection scenario, the network side device may send an SCG processing command to the terminal according to the service requirements, so that the terminal adjusts the status of one or several SCGs connected, or the status of one or several SCGs to be connected It is the first state, and the above-mentioned first state may be activated state, deactivated state, idle state, connected state, etc., which are adjusted to different states according to different service requirements, and the terminal records relevant information about the state adjustment of each SCG above. There may be various recorded SCG state adjustment information, such as: the previous state of the SCG, the time spent in adjusting the state, whether a beam failure or wireless link failure is detected during the state adjustment process.

The information related to the state adjustment of the SCG recorded above may be saved in the form of a new report, or recorded in the existing UE movement history information on the SCG side, or recorded in other existing reports.

The method for processing SCG status information provided by the embodiments of the present disclosure records SCG status-related information in a multi-connection scenario and reports the SCG status-related information to the network side, so that the network side can understand SCG status changes and judge the SCG side. Whether the uplink and downlink of the PSCell and the network side are synchronized, etc., can further assist the network side to optimize SCG activation or deactivation decisions and related configurations.

Specifically, when the terminal is in a multi-connection scenario, the state of the SCG to which the PSCell currently accessed by the terminal belongs is active, and there is a one-to-one correspondence between the PSCell and the SCG, the terminal can determine the PSCell according to the currently accessed PSCell. The SCG to which the PSCell belongs. The above-mentioned currently accessed PSCell may be a target PSCell after terminal handover, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in an active state, or it may be a source PSCell, that is, a normally connected PSCell. At this time, the terminal has no business needs, or considering energy saving, the network side sends an SCG deactivation instruction to the terminal through the master node MN or the secondary node SN, and the terminal receives the instruction, deactivates the SCG, and records the status information of the SCG on the terminal side. It is beneficial for the network side to understand the SCG status changes, determine whether the SCG side PSCell is synchronized with the downlink or uplink DL/UL of the network, and further assist the network side to optimize SCG activation or deactivation decisions and related configurations.

Similarly, when the state of the PSCell currently accessed by the terminal or the SCG to which the PSCell to be accessed belongs is deactivated, the PSCell to be accessed refers to the target PSCell to which the terminal needs to switch, and the target PSCell is a network-side reconfiguration PSCell, and the SCG to which the PSCell belongs is deactivated. At this time, because the SCG to which the target PSCell belongs is in a deactivated state, the UE will not perform random access to the target PSCell immediately. When the network side has a new service requirement for the terminal, and the SCG is in the deactivated state, the terminal does not monitor the PDCCH on the SCG side, and does not perform PUSCH transmission. Then, it is necessary to activate the SCG to which the PSCell currently accessed by the terminal belongs as soon as possible, or activate the SCG to which the PSCell to be accessed belongs to as soon as possible, and randomly access the PSCell to be accessed. It is conducive to the rapid recovery or establishment of the data transmission channel, so as to carry out new business or data transmission. Therefore, the network side sends an SCG activation instruction to the terminal through the master node MN or the secondary node SN, and the terminal receives the instruction, activates the SCG, and records the status information of the SCG on the terminal side.

There are many kinds of specific state information for recording that the SCG is in the first state, for example: in the case of receiving an SCG activation instruction, record the state of the SCG as the activated state or the deactivated state, and whether a beam is detected during the activation of the SCG failed, or the wireless link failed. In the case of receiving the SCG deactivation instruction, record the state of the SCG as the activated state or the deactivated state, and whether beam failure or radio link failure is detected during the SCG deactivation process.

The above SCG activation instruction and SCG deactivation instruction may be sent by the master node MN or the secondary node SN in the network device.

SCG's PSCell ID;

The number of times the SCG is in the first state;

Time information when the SCG is in the first state;

Wherein, the first state is an activated state or a deactivated state.

Specifically, when the terminal records the status information of the SCG, it can use any one or a combination of the following methods:

1. The PSCell ID of the SCG, that is, the PSCell ID currently accessed by the terminal or the PSCell to be accessed Identification information.

When the terminal is in a multi-connection scenario, the terminal is connected to a PSCell, and the state of the SCG to which the PSCell belongs is activated. When the terminal has no business needs or in order to save energy, the network side will send an SCG deactivation command, and the terminal will deactivate the SCG of the SCG. During the process, the identifier of the currently accessed PSCell or the identifier of the PSCell to be accessed is recorded, and there is a one-to-one correspondence between the PSCell identifier and the SCG. Deactivating the PSCell means setting the SCG to which the PSCell belongs to the deactivated state. For a normal SCG deactivation command, that is, the deactivation command is not accompanied by a synchronous reconfiguration command, then the UE records the currently accessed PSCell ID. For the SCG deactivation command sent to the UE together with the synchronous reconfiguration command, that is, at this time The state of the SCG to which the target PSCell belongs is configured as a deactivated state. At this time, the UE may record the source PSCell ID or the target PSCell ID. ID.

When the terminal is connected or waiting to be connected to a PSCell, and the state of the SCG to which the PSCell belongs is deactivated, there is a need for new services or data transmission, and the network side sends an SCG activation command, the terminal will record the current The identifier of the accessed PSCell, and there is a one-to-one correspondence between the PSCell identifier and the SCG, and activating the PSCell means setting the SCG to which the PSCell belongs to an active state. For ordinary SCG activation commands, if the SCG activation command is not sent together with the synchronous reconfiguration command, the terminal needs to determine whether the network has reconfigured the target PSCell to which the terminal needs to switch before receiving the SCG activation command, and the target PSCell The SCG to which it belongs is deactivated. If the target PSCell was reconfigured on the network side before, and the SCG to which the target PSCell belongs is deactivated, activate the target PSCell after receiving the SCG activation command, and record the target PSCell ID; if the target PSCell has not been reconfigured on the network side before , and the SCG to which the target PSCell belongs is in the deactivated state, after receiving the SCG activation instruction, activate the SCG to which the PSCell currently accessed by the terminal belongs, that is, set the SCG to which the PSCell currently accessed by the terminal belongs to the activated state. If the SCG activation command is sent together with the synchronous reconfiguration command, and the target PSCell is configured in the synchronous reconfiguration command, the terminal accesses the target PSCell and records the target PSCell identifier.

The above-mentioned PSCell identifier can be represented by a form of PSCell ID, and the above-mentioned PSCell ID can be represented by a physical cell identifier (Physical Cell Identifier, PCI) and a frequency point, or a global cell identifier (Cell Global Identifier, CGI).

2. First indication information used to indicate that the SCG is in the first state.

In one entry, it indicates that the SCG state is deactivated. This entry is used To record information related to this SCG deactivation process.

3. The number of times the SCG is in the first state, that is, the number of times the SCG state to which the PSCell currently accessed by the terminal or the PSCell to be accessed by the terminal is in the active state, or the number of times the SCG is in the deactivated state.

When the terminal receives the SCG deactivation instruction, when the terminal maintains the connection to the PSCell it is currently accessing, or after determining the PSCell to be accessed, the terminal remains connected to the PSCell to be accessed, and the PSCell to which the above-mentioned PSCell belongs The number of times the SCG state changes to the deactivated state; or the number of times the terminal changes the SCG state to which the PSCell belongs to the active state during the process of maintaining the connection with the currently accessed PSCell when the SCG activation instruction is received. The above-mentioned currently accessed PSCell may be a target PSCell after terminal handover, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in an active state, or it may be a source PSCell, that is, a normally connected PSCell.

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

When the terminal receives the SCG deactivation instruction, the specific time information of the deactivation state of the PSCell the terminal is currently accessing or the SCG to which the PSCell to be accessed belongs; or when the terminal receives the SCG activation instruction, the terminal’s current Specific time information of when the SCG to which the accessed PSCell belongs is in the active state. The above-mentioned currently accessed PSCell may be a target PSCell after terminal handover, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in an active state, or it may be a source PSCell, that is, a normally connected PSCell.

5. The second indication information is used to indicate whether the timing advance timer TAT times out, that is, whether the TAT times out each time the SCG is activated or each time the SCG is in a deactivated state.

When the terminal receives the SCG deactivation instruction, record whether the TAT corresponding to the SCG times out when the PSCell that the terminal accesses or the SCG to which the PSCell to be accessed belongs to is in the deactivation state; or when the terminal receives the SCG In the case of an activation command, whether the TAT corresponding to the SCG times out when the SCG to which the PSCell to which the terminal is connected is activated each time.

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

Record when the terminal receives the SCG deactivation instruction, whether the PSCell that the terminal accesses or the SCG to which the PSCell to be accessed belongs to is in the deactivation state, whether it detects beam failure; or the terminal receives the SCG activation instruction In this case, whether the SCG to which the PSCell to which the terminal is connected belongs detects a beam failure every time it is activated.

7. The fourth indication information is used to indicate whether a radio link failure is detected, that is, whether a radio link failure is detected each time the SCG is activated, or when the SCG is deactivated each time ( Radio Link Failure, RLF).

When the terminal receives the SCG deactivation command, record whether the terminal has detected a radio link failure RLF each time the PSCell that the terminal accesses or the SCG to which the PSCell belongs to is in the deactivation state; or the terminal receives In the case of an SCG activation instruction, whether to detect a radio link failure RLF each time the SCG to which the PSCell to which the terminal is connected belongs is activated.

The method for processing SCG status information provided by the embodiments of the present disclosure is to record specific related information of the SCG in the activated state or deactivated state in a multi-connection scenario, and report the specific related information of the SCG status to the network side, so as to facilitate The network side has a clearer understanding of SCG status changes, accurately judges whether the SCG side PSCell is synchronized with the network side uplink and downlink, and can further assist the network side to optimize SCG activation or deactivation decisions and related configurations.

When the terminal receives the SCG activation instruction, the terminal remains connected to a PSCell, the total duration of the SCG to which the PSCell belongs is in the active state, for example: when the UE stays in the PSCell process, the SCG to which the PSCell belongs is in the active state A total of two times, the duration is 1.5ms and 2ms respectively, then the total duration of the SCG to which the PSCell belongs is in the active state is 3.5ms.

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

the duration for which the SCG maintains the first state;

The SCG maintains the start time and end time of the first state.

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

The duration of the SCG maintaining the first state, that is, the duration of each time the SCG maintains the activated state or the deactivated state. When the terminal receives the SCG deactivation instruction, the duration of the SCG deactivation state each time, for example: in this PSCell access process, there are 5 deactivation state durations of 1 ms, 0.5 ms, and 0.3 ms respectively ms, 0.6ms, 2ms, which can be respectively recorded in each SCG deactivation entry; when the terminal receives the SCG activation instruction, the duration of each SCG is in the active state, for example: here PSCell access During the process, there are 2 activation times of 1 ms and 2 ms respectively, which can be recorded in each activation SCG entry;

The start time and end time of the SCG maintaining the first state, that is, the start time and end time of each time the SCG maintains the activation state or deactivation state, including absolute time and relative time, that is, UTC time can be recorded, and the distance from UE can also be recorded The time when the PSCell was just connected, for example: there are 5 deactivated states, and the corresponding start time and end time are {1ms, 2ms}, {5ms, 5.5ms}, {8ms, 8.3ms}, {11ms , 11.6ms}, {16ms, 18ms}, that is, the relative time of recording, which can be recorded in each deactivated SCG entry; or there are 2 activations, and the corresponding start time and end time are respectively {1ms , 2ms}, {5ms, 7ms}, that is, the relative time of recording, which can be correspondingly recorded in each activated SCG entry.

Beam identification and beam measurement results for detected beam failures.

Specifically, after receiving the SCG deactivation instruction sent by the network side, when the SCG is in the deactivation state each time, or receiving the activation instruction sent by the network side and activating the SCG each time, the terminal detects In the case of beam failure, it is also necessary to record information related to the beam where the beam failure occurs, including the beam identification and beam measurement results each time a beam failure is detected. During this deactivation process, there are multiple beam failures, and the beam identification and beam measurement results of each beam failure can be recorded in the form of a list.

The number of beam failure recovery times;

The number of times beam failures occurred.

Specifically, when the terminal receives the SCG deactivation instruction, during the SCG deactivation process, each time the terminal detects a beam failure, it will record the indication information of whether the beam failure is successfully restored, for example: a certain time If the indication information is true, it means that the beam failure recovery is successful. If the indication information of a certain time is false, it means that the beam failure recovery is unsuccessful. You can record the indication information whether the beam failure recovery is successful or not in the form of a list. In addition, the number of beam failure recovery times can also be recorded, and can also be recorded in the form of a list. Moreover, when the above indication information indicates that a certain or several times of beam failure recovery is successful, the corresponding beam identification and beam measurement results recovered each time the recovery is successful. In the case of multiple recovery successes, the beam identification and beam measurement results of each successful recovery can be recorded in the form of a list.

In addition, the number of beam failures that occur each time the SCG is in the deactivated state may also be recorded. When the terminal receives the SCG deactivation command, the terminal will record the number of beam failures during the deactivation process every time it detects beam failure during the SCG deactivation process, for example, the deactivation process If the number of times of beam failures is 3, then in the above case of detection of beam failures, the number of records of beam identification and beam measurement results for each detection of beam failures is the same as the number of times of beam failures in this record.

The method for processing SCG status information provided by the embodiments of the present disclosure, in a multi-connection scenario, Record the specific relevant information of the SCG in the activated state or deactivated state, and report the specific relevant information of the SCG state to the network side, so that the network side can understand the SCG state changes more clearly, and accurately determine the uplink and downlink between the PSCell on the SCG side and the network side Whether it is synchronized or not can further assist the network side in optimizing SCG activation or deactivation decisions and related configurations.

The reason for the wireless link failure;

The number of wireless link failure recovery times;

The number of times wireless link failures occurred.

Specifically, when the terminal receives the SCG deactivation instruction, when 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 the following or multiple:

The reason for the wireless link failure, for example: the reason for the wireless link failure this time is that T310 timed out, and during the SCG deactivation process, there may be multiple times of wireless link failures, record each time in the form of a list The reason for the wireless link failure.

The number of wireless link failure recovery times, for example: when a wireless link failure is detected, how many times the wireless link failure recovery is performed, whether it is successful or not, it is recorded.

The sixth indication information used to indicate whether the wireless link failure recovery is successful, that is, the indication information whether the wireless link failure recovery is successful each time, for example: the indication information of this wireless link failure recovery is true, indicating that the wireless link failure recovery The link failure recovery has succeeded, and the indication information of the wireless link failure recovery is false, indicating that the wireless link failure recovery failed (unsuccessful), and during the SCG deactivation process, there may be multiple wireless In the case of a link failure, the indication information indicating whether the wireless link failure recovery is successful for multiple times is recorded in the form of a list.

The number of radio link failures, that is, how many times the terminal has radio link failures during the SCG deactivation process when the terminal receives the SCG deactivation instruction.

Specifically, when the terminal receives the SCG deactivation instruction, when the terminal detects a radio link failure during the SCG deactivation process, it also needs to record relevant information about the radio link failure, including:

Each time the terminal deactivates the SCG, how many times the wireless link fails, that is, record The number of radio link failures during this SCG deactivation process, for example: the number of radio link failures during this deactivation process is 2 times. Then the corresponding number of recording times for recording the cause of each wireless link failure is the same as the number of times.

The activation mode used when the SCG is activated, the activation mode includes: random access channel RACH mode or random access channel RACH process mode;

The value of TCI state configured on the network side.

Specifically, when the terminal receives the SCG activation instruction, that is, the first state is the activated state, the SCG state information also includes any one or more of the following:

The activation methods used when recording SCG activation include: random access channel RACH mode or no random access channel RACH process mode (that is, RACH-less mode). For example, if the network side configuration indicates that the terminal adopts the RACH mode, the terminal adopts the RACH mode Access, if the network side is not configured to instruct the terminal to use the RACH method, the terminal will judge whether its own conditions meet the conditions for RACH-less access, such as whether the TAT has timed out or failed, whether it has detected beam failure, or whether it has detected a wireless link Failed, if the terminal meets the above conditions, that is, there is no timeout or failure of TAT, and no beam failure is detected, and no wireless link failure is detected, then the RACH-less access method is used. If the terminal cannot meet the RACH-less access If the access condition is not met, use the RACH method to access.

Instructions to indicate that TAT is running and not valid. According to the indication information, the network side can know that when the terminal UE receives the SCG activation command to activate the corresponding SCG, although the TAT is running, But at this time, the terminal and the network are out of synchronization.

It is used to indicate whether the network side is configured with the indication information of the transmission configuration indication state TCI state, for example: if this indication is true, it means that the network configures the TCI state in the SCG activation command when the SCG is activated.

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:

The value of the TCI state configured on the network side when the SCG is activated, that is, the value of the TCI state configured on the network is recorded. The network side receives the value of TCI state configured at that time and other auxiliary information related to SCG activation, and can know whether the value of TCI state configured at that time is appropriate.

The above SCG status information includes the record content of the activation state and the record content of the deactivation state, which can be recorded in the same report, or can be recorded in two reports respectively.

And after the terminal records the status information of the SCG, it can report the available indication to the network side, and the network obtains the status information of the SCG recorded by the terminal through the UE information procedure. 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 the UEInformationRequest message; the terminal UE reports the recorded SCG status information to the MN or SN through the UEInformationResponse message; when the MN or SN receives the SCG status information sent by the terminal UE, it understands the SCG status change , judging whether the PSCell on the SCG side is synchronized with the network downlink (Downlink, DL) or uplink (Uplink, UL), etc., and can further optimize SCG activation or deactivation decisions and related configurations.

Fig. 2 is the second schematic flow diagram of the method for processing SCG status information provided by an embodiment of the present disclosure. As shown in Fig. 2 , the method includes:

Step 201, receiving the state information that the SCG is in the first state sent by the terminal, wherein the state information that the SCG is in the first state is recorded by the terminal after receiving the SCG processing instruction sent by the network side device;

Step 202, based on the state information that the SCG is in the first state, determine Synchronization status of PSCell and network, and optimal activation or deactivation of SCG configuration;

The first state is an activated state or a deactivated state.

Specifically, currently, the terminal UE supports a multi-connection scenario. That is, the terminal is connected to one MCG and simultaneously connected to multiple SCGs. MCG contains one or more cells, which is the first cell group connected to UE; MCG includes primary cell PCell and secondary cell SCell, all cells in the primary cell group except the primary cell are called secondary cells, and the primary cell is the terminal UE The first cell connected in the MCG. The SCG contains one or more cells, which is the secondary cell group SCG added after the UE establishes a connection with the MCG. Among all the cells in the SCG, the first cell to which the terminal connects is called the primary secondary cell PSCell. The cells other than the PSCell in the secondary cell group are also called SCells.

When the terminal is in a multi-connection scenario, the network side device may send an SCG processing command to the terminal according to the service requirements, so that the terminal adjusts the status of one or several SCGs connected, or the status of one or several SCGs to be connected It is the first state, and the above-mentioned first state includes an activated state or a deactivated state, which are adjusted to different states according to different service requirements, and the terminal records and reports relevant information of the above-mentioned state adjustment of each SCG.

When the terminal is in a multi-connection scenario, the state of the SCG to which the PSCell currently accessed by the terminal is active, and there is a one-to-one correspondence between the PSCell and the SCG, the terminal can determine the PSCell to which the PSCell belongs according to the currently accessed PSCell. SCG. The above-mentioned currently accessed PSCell may be a target PSCell after terminal handover, the target PSCell is a PSCell reconfigured by the network, and the SCG to which the PSCell belongs is in an active state, or it may be a source PSCell, that is, a normally connected PSCell. At this time, the terminal has no business needs, or considering energy saving, the network side sends an SCG deactivation instruction to the terminal through the master node MN or the secondary node SN, and the terminal receives the instruction, deactivates the SCG, and records the status information of the SCG on the terminal side. That is, the terminal records the state information that it is in the deactivated state. It is beneficial for the network side to understand the SCG status changes, determine whether the SCG side PSCell is synchronized with the downlink or uplink DL/UL of the network, and further assist the network side to optimize SCG activation or deactivation decisions and related configurations.

Similarly, when the state of the PSCell currently accessed by the terminal or the SCG to which the PSCell to be accessed belongs is deactivated, the PSCell to be accessed refers to the target PSCell to which the terminal needs to switch, and the target PSCell is a network-side reconfiguration PSCell, and the SCG to which the PSCell belongs is deactivated. At this time, because the SCG to which the target PSCell belongs is in a deactivated state, the UE will not perform random access to the target PSCell immediately. When the network side has new service requirements for the terminal and the SCG is in the deactivated state, The terminal neither monitors the PDCCH on the SCG side nor transmits the PUSCH. Then, it is necessary to activate the SCG to which the PSCell currently accessed by the terminal belongs as soon as possible, or activate the SCG to which the PSCell to be accessed belongs to as soon as possible, and randomly access the PSCell to be accessed. It is conducive to the rapid recovery or establishment of the data transmission channel, so as to carry out new business or data transmission. Therefore, the network side sends an SCG activation instruction to the terminal through the master node MN or the secondary node SN, and the terminal receives the instruction, activates the SCG, and records the status information of the SCG on the terminal side. That is, the terminal records the status information that it is in the active state.

The terminal records state information that it is in a first state, where the first state includes an activated state or a deactivated state. There are many kinds of specific state information for recording that the SCG is in the first state, for example: in the case of receiving an SCG activation instruction, record the state of the SCG as the activated state or the deactivated state, and whether a beam is detected during the activation of the SCG failed, or the wireless link failed. In the case of receiving the SCG deactivation instruction, record the state of the SCG as the activated state or the deactivated state, and whether beam failure or radio link failure is detected during the SCG deactivation process.

The above recorded state information that the SCG is in the first state may be saved in a new report, or recorded in the existing UE movement history information on the SCG side, or recorded in other existing reports. The network device may send the above SCG activation instruction and SCG deactivation instruction to the terminal through the master node MN or the secondary node SN.

If the network side device is the master node MN, the MN directly performs analysis and optimization, or the MN sends all or part of the received state information recording that the SCG is in the first state to the slave node through the X2 or Xn interface SN, the analysis and optimization is performed by the SN, or the analysis and optimization is jointly performed by the MN and the SN;

Specifically, after the terminal in the multi-connection scenario records the SCG state information, it can report the SCG state information to the master node MN, and the MN sends the received information completely or partially to the secondary node through the X2 or Xn interface. Node SN, analyzed and optimized by SN, or jointly by MN and SN Analyze and optimize;

Or, directly send the recorded SCG status information to SN for analysis and optimization by the SN side;

Alternatively, the recorded SCG status information is directly sent to the MN, and the MN side performs analysis and optimization.
