Abstract: An apparatus comprising a first node operating as a master node (MN) in a dual connectivity is provided. The apparatus may include at least one transceiver and at least one processor coupled to the at least one transceiver. The at least one processor may be configured to receive, from a second node operating as a secondary node (SN) through an Xn interface, an SN modification required message. The SN modification required message may include indication information for an MN-terminated split bearer. The indication information may indicate availability of an uplink (UL) usage at the SN. The at least one processor may be configured to identify a UL primary path of the MN-terminated split bearer, based on the indication information for the MN-terminated split bearer, and transmit, to a user equipment, information for indicating the UL primary path. The UL primary path is associated with one of a master cell group of the MN and a secondary cell group of the SN.

Abstract: An electronic device is disclosed and includes a communication circuit configured to transmit and receive a signal, a processor, and a memory configured to be electrically connected with the processor. The processor is configured to allow the communication circuit to receive data for a handoff from a server, determine a target access point (AP) of a connection after the handoff among candidate target APs based on the data for the handoff, and determine a handoff trigger point based on the data for the handoff and trigger a handoff to the target AP if a position of the electronic device meets the determined handoff trigger point.
