It should be noted that in the embodiment of this application, only the base station in the NR system is used as an example, but it does not Specific types of base stations are defined.

For ease of understanding, the following describes some of the content involved in the embodiments of this application:

At present, in a mobile communication system, two wireless access nodes/base stations can be deployed for a terminal to provide service transmission for the terminal at the same time, that is, a dual connection mode. There are two network nodes in the dual connection mode, one of which is called the master node (MN) and the other is called the secondary node (SN). At each network node, carrier aggregation technology (Carrier Aggregation, CA) can also be used, that is, a series of serving cells controlled by the node are configured for the UE, and this series of serving cells is also called a cell group. The cell group controlled by the master node MN is called the master cell group (MCG, Master Cell Group), and the cell group controlled by the secondary node SN is called the secondary cell group (SCG, Secondary Cell Group). Each cell group includes a special cell (Special Cell, SpCell) and a series of secondary cells (Secondary Cell, SCell). In the MCG, the special cell is called the Primary Cell (PCell), and in the SCG, the special cell is called the Primary Secondary Cell (PSCell).

At present, there is an ambiguous period of SCG status in the SCG status control process, that is, when the network side judges that the UE has no uplink data to send, and the network side has no downlink data to send, the MN or SN initiates SCG deactivation, and the MN sends the UE Send a deactivation command to the UE. Before the UE receives the SCG deactivation command, the terminal may have uplink data on the SCG again, and at this time, the UE will send a BSR or initiate a random access on the SCG. At this time, the SN thinks that the UE wants to activate the SCG, and puts the UE in the active state, and the SN at the SN side thinks that the SCG has entered the active state. At this time, the UE receives an SCG deactivation command from the MN, and the SCG enters a deactivation state at the UE side. The SN notifies the MN of the SCG activated state, and the MN considers the UE to be in the SCG activated state. As a result, the understanding of the state of the SCG by the UE and the network side is opposite, and thus there is a problem of ambiguity of the state of the SCG.

The method for controlling the state of the secondary cell group provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

Referring to FIG. 2, FIG. 2 is one of the flowcharts of a method for controlling the state of a secondary cell group provided in an embodiment of the present application. As shown in FIG. 2, the method for controlling the state of a secondary cell group includes the following steps:

Step 201, the first network element sends target information and/or receives target information, wherein the target information is used to control the secondary cell group SCG state of the terminal.

Wherein, the first network element may be the MN and/or the SN.

In this embodiment of the present application, the first network element sends target information and/or receives target information, where the target information is used to control the secondary cell group SCG state of the terminal. In this way, controlling the SCG state through the target information can reduce the resources consumed by the network side and reduce the power consumption of the terminal.

Optionally, the receiving target information includes:

Receiving first indication information sent by the second network element, where the first indication information is used to indicate at least one of the following:

The first network element directly activates the first authorization information of the SCG;

The first network element directly deactivates the second authorization information of the SCG.

Wherein, the target information may include first indication information.

Wherein, the first network element may be an MN, and the second network element may be an SN; or, the first network element may be an SN, and the second network element may be an MN.

In one embodiment, when the first indication information is used to indicate the first network element to directly activate the first authorization information of the SCG, it may instruct the first network element to determine whether to Allows direct activation of SCG, for example:

If the activation of the SCG is triggered by the terminal, allowing the first network element to directly activate the SCG;

If the activation of the SCG is triggered by the first network element, the first network element is not allowed to directly activate the SCG.

For example, the MN (second network element) indicates to the SN (first network element) that if the terminal triggers the SCG activation process, and if the SCG activation reason is recovery of MCG (MCG recovery), the first network element is allowed to Direct activation of SCG.

For example, the first network element is MN, the second network element is SN, downlink (Down Link, DL) data arrives at MN, and MN prepares to use SCG to transmit the described DL data, then it can be considered that MN triggers and activates SCG; terminal By sending the SCG activation request, it can be considered that the terminal triggers to activate the SCG. The terminal initiates a random access or scheduling request on the SCG/PSCell, which may also be considered as the terminal sending the SCG activation request.

In one embodiment, when the first indication information is used to instruct the first network element to directly deactivate the second authorization information of the SCG, it may instruct the first network element to deactivate the SCG according to the trigger condition Determines whether direct SCG deactivation is allowed, for example:

If the deactivation of the SCG is triggered by the terminal, allowing the first network element to directly deactivate the SCG;

If the deactivation of the SCG is triggered by the first network element, the first network element is not allowed to directly deactivate the SCG.

For example, the first network element is MN, and the second network element is SN. The terminal requests the MN to deactivate the SCG due to overheating or low battery. At this time, if the MN obtains the second authorization, it can first deactivate the SCG and then notify the SN. ; If the deactivation of the SCG is triggered by the MN, the MN is not allowed to directly deactivate the SCG.

For example, if the terminal sends an SCG deactivation request, it may be considered that the terminal triggers SCG deactivation. For example, the terminal sends UE assistance information, which indicates SCG deactivation indication/request information.

It should be noted that when the downlink data arrives at the MN and the MN wants to activate the SCG to use SCG resources, the MN needs to send an SCG activation request to the SN, and then send the SCG activation request to the UE after receiving the SN’s acceptance response to the activation request. commands, resulting in less effective SCG state control. In this embodiment, the SN may pre-send the authorization to activate the SCG to the MN in some cases, that is, the MN is allowed to send the SCG activation to the UE without the confirmation of the SN. Correspondingly, when the conditions are not allowed, the SN can also cancel the authorization, so as to improve the effectiveness of the SCG state control.

In this embodiment, the first indication information sent by the second network element is received, and the first indication information is used to indicate at least one of the following: the first authorization information for the first network element to directly activate the SCG; the first The network element directly deactivates the second authorization information of the SCG. In this way, the first network element can directly activate or deactivate the SCG based on the first indication information, which can realize fast activation or deactivation of the SCG, can improve the effectiveness of the SCG state control, and can solve the problem that the effectiveness of the current SCG state control is low. problem; and can avoid frequent signaling interaction of the Xn interface.

Optionally, the method also includes:

The first network element sends a response to the first indication information to the second network element; and/or,

The first network element sends a first request to the second network element, where the first request is used to request the second network element to send the first indication information.

In one embodiment, before the first network element receives the first indication information sent by the second network element, the first network element sends a request to the second network element, requesting the second network element to send the target information; the first After the network element receives the first indication information sent by the second network element, the first network element sends a response to the first indication information to the second network element.

For example, the MN applies to the SN for the first authorization, the SN configures or grants the first authorization to the MN, and the MN sends an acknowledgment of the first authorization to the SN.

Optionally, the first authorization information is used to indicate at least one of the following:

A first authorization, where the first authorization is used to indicate that the first network element is allowed to directly activate the SCG;

activate said first authorization;

deactivating or canceling said first authorization;

Not authorizing or allowing the first network element to directly activate the SCG;

the effective time of said first authorization;

The associated SCG configuration of the first authorization.

Wherein, within the valid time, the first authorization may be considered valid; if it is outside the valid time, it may be considered that the first authorization is cancelled.

In one embodiment, when the second network element authorizes the first network element to directly activate the SCG, the second network element sends to the first network element SCG information that allows the first network element to send to the terminal, so The SCG information includes the associated SCG configuration of the first authorization.

It can be understood that the SCG configuration information associated with the first authorization is SCG configuration information sent to the terminal if the SCG is directly activated by the first network element during the valid period of the first authorization. If the first authorization is not valid (for example, the validity period of the first authorization has expired), the first network element may delete the stored associated SCG configuration.

Optionally, the second authorization information is used to indicate at least one of the following:

A second authorization, where the second authorization is used to indicate that the first network element is allowed to directly deactivate the SCG;

activate said second authorization;

deactivate or cancel said second authorization;

Not authorizing or allowing the first network element to directly deactivate the SCG;

the validity period of said second authorization;

The associated SCG configuration of the second authorization.

In one embodiment, when the second network element authorizes the first network element to directly deactivate the SCG, the second network element sends to the first network element SCG information allowing the first network element to send to the terminal, The SCG information includes the associated SCG configuration of the second authorization.

It can be understood that the SCG configuration information associated with the second authorization is SCG configuration information sent to the terminal if the SCG is directly deactivated by the first network element during the valid period of the second authorization. If the second authorization is not valid (for example, the validity period of the second authorization has passed), the first network element may delete the stored associated SCG configuration.

Optionally, the associated SCG configuration of the first authorization includes at least one of the following:

After the SCG is activated, the target state of at least one serving cell in the SCG;

After the SCG is activated, the number or list of immediately activated serving cells in the SCG;

After the SCG is activated, the available uplink resources of the SCG;

After the SCG is activated, the downlink resources available to the SCG.

For example, after the SCG is activated, the UE can have available uplink resources such as random access resources, PUCCH resources, and configured grants. Or have available reference signal resources to perform measurements.

Optionally, the associated SCG configuration of the second authorization is used to indicate at least one of the following:

After the SCG is deactivated, the terminal clears at least part of the downlink resources of the SCG;

After the SCG is deactivated, the terminal clears at least part of the uplink resources of the SCG;

After the SCG is deactivated, the terminal does not perform a first operation on the SCG, and the first operation includes at least one of the following:

Beam management, beam failure detection (Beam Failure Detection, BFD), beam failure recovery (Beam Failure Recovery, BFR), channel state information (Channel State Information, CSI) measurement, CSI measurement reporting, random access, wireless link detection ( Radio Link Monitoring, RLM) measurement, radio resource management (Radio Resource Management, RRM) measurement.

For example, after the SCG is deactivated, the random access resources of the SCG are deleted by associating the SCG configuration information, thereby saving network uplink resources. It can be understood that, in some cases, the associated SCG configuration of the second authorization may also be generated by the first network element.

Optionally, the method also includes:

When the SCG of the terminal is directly activated or deactivated by the first network element, the first network element indicates the state of the SCG to the second network element.

The following uses a specific embodiment to illustrate. In this embodiment, the first network element is the MN, the second network element is the SN, and the method for controlling the state of the secondary cell group includes the following process:

The SN sends the first indication information to the MN;

The MN sends a response to the first indication information to the SN.

Wherein, the first indication information can be sent at any time, for example, SN addition (increase), SN change (change), SN reconfiguration, SCG is in a deactivated state, and the first indication information is sent when the SCG is in an activated state.

In one embodiment, before the MN receives the first indication information sent by the SN, the MN sends a request to the SN, requesting the SN to send the target information; after the MN receives the first indication information sent by the SN, the MN sends a request to the SN for the response to the first indication message.

Currently, when downlink data arrives at the MN and the MN wants to activate the SCG to use SCG resources, the MN sends an SCG activation request to the SN, and sends an SCG activation command to the UE after receiving the SN's acceptance response to the SCG activation request. In this embodiment, in order to achieve fast SCG activation, the SN may pre-send an authorization to activate the SCG to the MN in some cases, that is, allowing the MN to directly activate the UE's SCG without SN confirmation or participation. Correspondingly, when conditions do not permit, the SN can also cancel the authorization. Therefore, the activation and deactivation of the SCG can be accelerated, and the effectiveness of controlling the state of the SCG can be improved.

Optionally, the receiving target information includes receiving target information sent by a second network element, where the target information includes at least one of the following:

SCG status indication information;

Instructing the first network element to cancel sending the indication information of the SCG deactivation command to the terminal;

Instructing the first network element to send indication information of an SCG activation command to the terminal.

The following uses a specific embodiment to illustrate. In this embodiment, the first network element is the MN, the second network element is the SN, and the method for controlling the state of the secondary cell group includes the following process:

(1): SN initiates an SCG deactivation request;

(2): The MN sends an acceptance response of the SCG deactivation request to the SN;

(3): Before the UE receives the SCG deactivation command sent by the MN, if the uplink data arrives and there is no PUSCH resource, the UE initiates RACH or SR to the SCG;

(4): After receiving the RACH or SR of the UE, the SN judges the status of the SCG based on the information therein;

(5): If the SN judges that the SCG is still in the activated state, the SN sends to the MN indication information for indicating the status of the SCG (indicating that the SCG of the UE is currently in the activated state) and/or requesting to cancel the transmission of the SCG deactivation command;

(6): After receiving the indication information sent by the SN, the MN cancels the delivery of the SCG deactivation command, or sends the SCG activation command to the UE.

Therefore, after the MN receives the SCG activation notification, if the SCG deactivation command has not been sent, the MN can cancel the transmission, and if the SCG deactivation command has been sent, the MN can send the SCG activation command to the UE again, which can solve the problem of ambiguous SCG status. question.

In this embodiment, by receiving the target information sent by the second network element, it is possible to avoid inconsistent understanding of the SCG state between the network side and the terminal, thereby avoiding subsequent misconfigurations caused by inconsistent understanding of the SCG state between the network side and the terminal, and avoiding communication anomaly, thereby improving the stability of SCG activation-deactivation control.

Optionally, the target information includes at least one of the following:

SCG deactivation request;

SCG deactivation indication;

SCG activation request;

SCG activation indication;

SCG status indication information.

Wherein, the SCG deactivation instruction includes a response to the SCG deactivation request initiated by the second network element, or the first network element may instruct the second network element to deactivate the SCG. The SCG activation instruction includes a response to the SCG activation request initiated by the second network element, or the first network element may instruct the second network element to activate the SCG. The SCG state indication information is used to indicate the current state of the SCG.

Optionally, after the first network element sends the target information and/or receives the target information, the method further includes:

The first network element starts a timer.

Optionally, after the first network element starts the timer, the method further includes:

The first network element does not perform at least one of the following during the running of the timer:

Deliver some or all of the targeted information;

Activate the SCG;

deactivate the SCG;

Responding to the SCG activation request of the terminal;

Responding to the terminal's SCG deactivation request.

In one embodiment, not activating the SCG may include at least one of the following:

Do not schedule SCG;

Does not respond to UE random access or SR;

Does not respond to UE's SCG activation request.

In this embodiment, by limiting the behavior that the first network element does not perform during the running of the timer, the problem of ambiguity of the SCG state can be solved, thereby improving the stability of the SCG activation and deactivation control.

Optionally, when the timer expires or is not running, the behavior of the first network element includes at least one of the following:

Allow the delivery of said targeted information;

Allows to deactivate the SCG;

Allows SCG to be activated;

allow to respond to the terminal's SCG activation request;

It is allowed to respond to the terminal's SCG deactivation request.

In this embodiment, the timer can be used to maintain the synchronization of the SCG state between the first network element and the second network element. After the first network element sends and/or receives the target information, the first network element starts the timer, which can make The network side keeps the synchronization of the SCG state.

Optionally, the method further includes: when at least one of the following conditions is met, the first network element stops the timer:

Receive SCG deactivation request;

In one embodiment, when the target information includes SCG activation request, SCG activation indication or SCG status indication information, if the first network element receives the SCG release request or indication, the first network element stops the timing device.

For example, after the first network element sends the SCG deactivation request to the second network element, the first network element starts the timer, and during the running of the timer, the first network element no longer sends the SCG deactivation request. During the running of the timer, if the first network element receives an indication from the second network element that the SCG has been successfully deactivated, the first network element stops the timer, or the first network element does not stop the timer at this time , during the running of the timer, the first network element does not send an SCG activation request.

For another example, after the SCG deactivation instruction sent by the first network element to the second network element (the SCG deactivation instruction may also be a response to the SCG deactivation request sent by the second network element), start the timer . During the running of the timer, the first network element does not schedule the UE. When the timer is running, if the first network element receives an indication that the SCG indicated by the second network element has been successfully deactivated, the first network element stops the timer. If the timer expires, the first network element resumes scheduling the UE, or responds to information sent by the UE on the SCG.

In one embodiment, the first network element is the SN, the second network element is the MN, and the SN starts the timer after sending one of the following information to the MN:

No SCG deactivation request is sent to the MN;

No SCG activation request is sent to the MN;

Do not activate SCG;

The status indication information of the SCG is not sent to the MN.

Wherein, during the running of the timer, the SN does not send an SCG deactivation request to the MN, thereby prohibiting the SN from making frequent requests in a short period of time; during the running of the timer, the SN does not send an SCG activation request to the MN, thereby enabling The SN is prohibited from changing the SCG state frequently in a short period of time; during the running of the timer, the SN does not activate the SCG, thereby avoiding potential state inconsistencies caused by the SN activating the SCG by itself.

For example, after the SN sends the SCG deactivation request to the MN, the SN starts the timer, and during the running of the timer, the SN does not schedule the SCG. If the SN receives an indication from the MN that the SCG has been successfully deactivated during the running of the timer, the SN stops the timer. If the SN stops the timer after receiving the MN's rejection response to the SCG deactivation request during the running of the timer, the SN can resume scheduling the SCG.

No SCG activation request is sent to SN;

No SCG deactivation request is sent to SN;

Do not activate SCG;

Not responding to UE's SCG activation request;

The status indication information of the SCG is not sent to the MN.

Optionally, the sending target information includes:

If the first network element receives the random access message or the scheduling request sent by the terminal, and the random access message or the scheduling request does not include the second indication information, the first network element sends The terminal sends third indication information;

Wherein, the second indication information is used to indicate that the SCG is requested to be activated or the current state of the SCG is deactivated, and the third indication information is used to indicate that the terminal ignores the SCG received from the second network element Deactivate command.

The following uses a specific embodiment to illustrate. In this embodiment, the first network element is an SN, and the second network element is an MN. The method for controlling the state of a secondary cell group includes the following process:

(1): When the SCG of the UE is in the deactivated state, if uplink data arrives at the SCG, the UE initiates a RACH or SR to the SCG or the UE initiates a random access (RACH) or a scheduling request (Scheduling Request, SR) to the SCG Afterwards, the UE indicates to the SCG that it requests to activate the SCG, or indicates that the current state of the SCG is a deactivated state;

(2): The UE receives indication information from the SN, and the indication information indicates whether the UE should execute the SCG deactivation command received from the MN. If the UE is instructed to execute the SCG deactivation command, the UE deactivates the SCG; if the UE is instructed to ignore the SCG deactivation command, the UE does not deactivate the SCG.

In this embodiment, if the first network element receives a random access message or a scheduling request sent by a terminal, and the random access message or the scheduling request does not include the second indication information, then the The first network element sends the third indication information to the terminal, which can solve the problem of ambiguity of the SCG state, thereby improving the stability of SCG activation and deactivation control.

Optionally, the receiving target information includes:

The first network element receives the SCG activation request sent by the second network element;

The method also includes:

The first network element sends the current state of the SCG to the second network element.

In an implementation manner, the first network element sends the current state of the SCG to the second network element, and the current state of the SCG does not trigger the second network element to send an SCG activation command to the UE.

In one embodiment, the first network element receives the SCG activation request sent by the terminal, the first network element activates the SCG of the terminal, the first network element receives the SCG activation request sent by the second network element, and the first network element sends an SCG activation request to the terminal. The second network element sends the current state of the SCG.

Optionally, the target information is used for at least one of the following:

Indicating the current state of the SCG to the terminal;

indicating the SCG configuration to the terminal;

Instructing the terminal to ignore part or all of the SCG configuration information received from the second network element within the first preset time period.

Wherein, the first preset duration may be 500ms, or 1s, or 5s, etc., which is not limited in this embodiment.

In one embodiment, the first network element receives the SCG activation request from the second network element, and the first network element sends an approval response to the SCG activation request to the second network element; the terminal receives the SCG activation request sent by the second network element. Before the command, the terminal initiates a random access request or a scheduling request, and requests the first network element to activate the SCG; the first network element receives the terminal's SCG activation request, and judges that the terminal has not received the second network element before sending the SCG activation request The SCG activation command sent indicates the current status of the SCG to the terminal, or indicates the configuration of the SCG to the terminal, or indicates to the terminal that the terminal ignores the partial or All SCG configuration information.

The following is illustrated by two specific examples. Wherein, the first network element is the SN, and the second network element is the MN.

Example 1:

The method for controlling the state of the secondary cell group includes the following processes:

(1): The SCG of the UE is in a deactivated state;

(2): UE has uplink data to send, and requests SN to activate SCG, such as initiating RACH or scheduling request;

(3): The SCG of the UE is activated;

(4): The SN receives the SCG activation request sent by the MN. For example, the SCG activation request may be sent by the MN to the SN after downlink data arrives at the MN. When the SN has not notified the MN that the SCG has been activated, the SN receives the SCG activation request sent by the MN;

(5): The SN sends SCG status indication information to the MN, where the SCG status indication information is used to indicate the current status of the SCG. Further, the SCG status indication information does not trigger the MN to send an SCG activation command to the UE.

Example 2:

The method for controlling the state of the secondary cell group includes the following processes:

(1): SCG is in a deactivated state;

(2): The SN receives the SCG activation request sent by the MN;

(3): The SN sends a response to the SCG activation request to the MN. For example, to confirm that the SCG can be activated;

(4): Before the UE receives the SCG activation command sent by the MN, the UE has uplink data to send on the SCG, and requests the SN to activate the SCG, such as initiating a RACH or scheduling request;

(5): The SN receives the UE's SCG activation request and judges that the UE has not received the SCG activation command sent by the MN before sending the message, and the SN sends any one of the following instructions to the UE:

SCG status indication information;

SCG configuration;

Indicates whether the UE ignores all or part of the SCG status information and/or all or part of the SCG configuration information received from the MN within a period of time. For example, the SN instructs the UE to activate the SCG and reconfigure part of the SCG configuration, and instructs the UE not to initiate random access if it receives the SCG synchronous reconfiguration parameters from the MN.

In this embodiment, the first network element sends the current state of the SCG to the second network element, or the first network element sends the target information, so that the terminal and the second network element can simultaneously send the first network element Meta-request to activate SCG's handling issues.

Referring to FIG. 3, FIG. 3 is the second flowchart of a method for controlling the state of a secondary cell group provided in an embodiment of the present application. As shown in FIG. 3, the method for controlling the state of a secondary cell group includes the following steps:

Step 301, the terminal receives target information for controlling the SCG state of the secondary cell group.

Wherein, the second preset duration may be 500ms, or 1s, or 5s, etc., which is not limited in this embodiment.

A specific embodiment is used as an example to illustrate below. The method for controlling the state of a secondary cell group includes the following process:

(1): SN initiates an SCG deactivation request;

(2): The MN sends an acceptance response of the SCG deactivation request to the SN, and sends an SCG deactivation command to the UE;

(3): When the UE has not received the SCG deactivation command, the SCG of the UE is still in the activated state. If there is uplink data arriving at the SCG, if there is no PUSCH resource, the UE initiates RACH or SR to the SCG;

(4): The UE receives an SCG activation command from the SN;

(5): If the UE receives the SCG deactivation command from the MN within the preset time range of receiving the SCG activation command, the UE ignores the SCG deactivation command. Wherein, the preset time range may be determined by agreement or network configuration.

In this embodiment, after receiving the SCG deactivation command from the second network element within a relatively short period of time after receiving the SCG activation command from the first network element, the terminal ignores the received SCG deactivation command, which can solve the ambiguity of the SCG state Therefore, the stability of SCG activation and deactivation control can be improved.

The second SCG state control instruction may be used to control the state of the SCG, and may include at least one of the following: an SCG deactivation request, an SCG deactivation indication, an SCG activation request, or an SCG activation indication, and the like.

The foregoing preset priority may be used to indicate the highest priority among the first network element and the second network element. Exemplarily, the preset priority may include the priority of the first network element and the priority of the second network element.

The following uses a specific embodiment to illustrate. In this embodiment, the first network element is the MN, the second network element is the SN, and the method for controlling the state of the secondary cell group includes the following process:

(1): The SCG of the UE is in a deactivated state;

(2): The UE initiates an SCG activation request to the SN and receives an acceptance response from the SN;

(3): The UE receives the acceptance response of the SCG activation request from the SN; at the same time, the UE receives the SCG deactivation command from the MN;

(4): The UE takes the SCG deactivation command sent by the MN as a high priority, and ignores the SCG activation command sent by the SN.

In this embodiment, the terminal determines how to control the state of the SCG based on the defined priority, which can solve the problem of ambiguity in the state of the SCG caused when the terminal receives the SCG state control instructions sent by the SN and the MN at the same time.
