Agree to remove the SCG information.
The method according to claim 21, wherein the information of the rejection condition deletion SCG comprises one or more of the following:

Determining one or more triggers to delete condition identifier information corresponding to the target cell;

One or more rejected configuration information after deleting the target cell;

The information for agreeing to delete the SCG includes one or more of the following:

One or more of the agreed triggers delete the condition identification information corresponding to the target cell;

One or more of the agreed triggers delete the conditional action time corresponding to the target cell;

One or more configuration information after the target cell is deleted.
The method according to claim 15, wherein the network node is a master node, and after the sending the conditional deletion SCG information to the terminal device, the method further includes:

Receiving configuration confirmation information sent by the terminal device;

Sending conditional deletion SCG confirmation information to the secondary node according to the configuration confirmation information;

or,

The network node is a secondary node, and after the sending the conditional deletion SCG information to the terminal device, the method further includes:

Receiving configuration confirmation information sent by the terminal device;

According to the configuration confirmation information, the conditional deletion SCG confirmation information is transmitted to the master node.
The method according to claim 14, wherein after the sending the conditional deletion SCG information to the terminal device, the method further comprises:

Receiving a notification message sent by the terminal device;

The notification message is used to notify the network node of the information about the SCG deleted by the terminal device.
The method of claim 15, wherein the network node is a master node, the method further comprising:

And sending, to the secondary node, the information about the cancellation condition to delete the SCG, where the cancellation condition deletes the related information of the SCG, where the secondary node determines that the corresponding conditional deletion SCG cell has been canceled;

or,

The network node is a secondary node, and the method further includes:

Sending a cancellation condition to the primary node to delete information about the SCG, the cancellation condition deleting the related information of the SCG for the primary node to determine that the corresponding conditional deletion SCG cell has been canceled.
The method of claim 25, wherein the canceling the condition to delete the SCG related information comprises one or more of the following:

Identification information of the target cell deleted by one or more canceled conditions;

One or more canceled triggers delete the condition identification information corresponding to the target cell;

One or more canceled configuration information after deleting the target cell;

Identification information of the terminal device.
A terminal device comprising:

a first receiving module, configured to receive conditional deletion SCG information sent by the network node;

An evaluation module, configured to delete the SCG information according to the condition, and determine whether one or more target cells of the SCG meet the condition corresponding to triggering the deletion of the target cell, and obtain an evaluation result;

And a triggering module, configured to trigger a process of deleting the SCG target cell according to the evaluation result.
A network node, including:

a third sending module, configured to send conditional deletion SCG information to the terminal device;

The conditionally deleting SCG information is used by the terminal device to delete SCG information according to the condition, and whether one or more target cells of the SCG meet the condition corresponding to triggering the deletion target cell, and obtain an evaluation result, and according to the evaluation. As a result, the process of deleting the SCG target cell is triggered.
A terminal device comprising a memory, a processor, and a computer program stored on the memory and operable on the processor, wherein the computer program is executed by the processor to implement claims 1 to 13 The step of the secondary cell group deletion method according to any one of the preceding claims.
A network node comprising a memory, a processor, and a computer program stored on the memory and operative on the processor, wherein the computer program is executed by the processor to implement claims 14 to 26 The step of the secondary cell group deletion method according to any one of the preceding claims.
A computer readable storage medium having stored thereon a computer program, wherein the computer program is executed by a processor to implement the steps of the secondary cell group deletion method according to any one of claims 1 to 26.
