The entire content of the application incorporated herein by reference.

Technical field

Background technique

Dual Connectivity (DC) technology provides two network nodes for terminals (also called User Equipment (UE)), that is, the resources of access network equipment. One of the network nodes is called the Master Node. MN), and the other is called the Secondary Node (SN). At each network node, carrier aggregation technology (CA) is used, that is, UE is configured with a series of serving cells controlled by the node, also called Cell Group (CG). The MN controls the Master Cell Group (MCG), and the SN controls the Secondary Cell Group (SCG). Each cell group contains a special cell (Special Cell, SpCell) and a series of secondary cells (Secondary Cell, Scell). In MCG, the special cell is called Primary Cell (PCell), and in SCG, the special cell is called Primary Secondary Cell (PSCell). In a cell group, SpCell uses the primary carrier, while other secondary cells use secondary carriers. Resource scheduling within a cell group is performed by SpCell.

During the process of changing the secondary cell group, such as the conditional primary and secondary cell group addition or change (CPAC) process, when a CPAC is completed, the configured CPAC condition configuration will be released and will not To retain candidate cells, you need to wait for the network to configure the CPAC condition configuration before the terminal can perform CPAC based on the new condition configuration. If the network does not reconfigure the CPAC condition configuration, the terminal will not have the opportunity to continue performing the CPAC process based on the previously configured CPAC candidate cell, and the terminal will not be able to perform cell switching in time. During the process of changing the conditional primary and secondary cells in the secondary node, the primary node may not know the CPC configuration configured by the secondary node, and thus cannot instruct the terminal and/or the target secondary node to retain these CPC configurations.

A2. The terminal performs a reconfiguration process. The reconfiguration process may be an SCG change process initiated by the network side device, or a CPC process.

A3. If the reconfiguration process does not change the secondary node key, that is, the SN_key or SK Counter is not changed, the terminal retains the N sets of target configurations; accordingly, the network side device also retains the N sets of target configurations.

If the reconfiguration process changes the secondary node key, that is, changes the SN_key or SK Counter, the terminal releases the N sets of target configurations; correspondingly, the network side device also releases the N sets of target configurations.
