- the release of the logical link between the two base stations can be achieved by the following steps: When the link between the two base stations needs to be released, first the base station 1 sends a message requesting the release of the link to the base station 2 (InterNodeB Connection Release); then 2 The base station releases the resources related to the link according to the message, and sends a link release complete message (InterNodeB Connection Release Complete) to the base station 1. Finally, after receiving the message that the link is released, the base station 1 releases itself IuNB link resources, thereby completing the release of the logical link between the base stations.

- the RNC then informs the UE (user equipment) to update the current active set stored on the UE side.
- the base station to which the primary cell belongs After establishing the IuNB link, the base station to which the primary cell belongs sends the updated "Active Set Routing Table Synchronization" message to the base stations to which all slave cells belong via the established IuNB data link, and then the base station to which the slave cell belongs controls the slave cell. Updates to the active set routing table. This process and subsequent cell synchronization information sent from the primary cell to the secondary cell belong to the content of "IuNB interface data transmission" in (3) in the figure.

- the RNC notifies the UE to update the activation set.
- the RNC sends a request to release the radio link to the exiting cell, and the exiting cell uses the IuNB control plane link release signaling 4 (InterNodeB Connection release) to notify the activation set. All cells in the network release link resources related to themselves. After all cells return to the exiting cell through IuNB control, a confirmation message of link release completion (InterNodeB Connection release complete) is returned, and the exiting cell releases resources related to the active set in the cell, and then notifies the RNC that the link is removed.
