Electronic apparatus in wireless communication system, and mobility measurement method

An electronic device in a wireless communication system, the electronic device comprising:

• circuitry, configured to
• communicate with a first node and a second node via different carriers for dual connectivity;
• initiate mobility measurement on at least one of the first node and the second node;
• determine a reporting mode for reporting measurement result of the mobility measurement among current dual-connection nodes, in association with likelihood of a radio link failure of the first node or the second node within a predetermined time from a current time and an expected duration between determination of available one or more target nodes and occurrence of the radio link failure of the first node or the second node, in advance to the radio link failure of the first node or the second node, based on expiration waiting time of timers for at least one of the first node and the second node, the expiration waiting time of timers being a difference between the current time and an expected time of the timers;
• report the measurement result of the first node to the first node, or, report the measurement result of the second node to the second node respectively, based on the determined reporting mode;
• and
• receive a confirmation from at least one of the first node and the second node, in response to a node transfer request sent from at least one of the first node and the second node to the one or more target nodes to change connection transfer mode, based on the determined reporting mode.
