1. A method for handling handover in a wireless communication system, the method comprising:
receiving, by a user equipment (UE), a radio resource control (RRC) message including a first measurement configuration and a second measurement configuration for detecting a plurality of neighboring cells from a serving cell;
identifying, by the UE, a first neighboring cell and a second neighboring cell from the plurality of neighboring cells having a signal strength above a predefined threshold based on the RRC message;
identifying, by the UE, that the first neighboring cell supports a next generation core entity to connect to the next generation core entity via the first neighboring cell and the second neighboring cell supports a legacy core entity to connect to the legacy core entity via the second neighboring cell;
determining, by the UE, whether a measurement identity (ID) of the first neighboring cell and a measurement ID of the second neighboring cell are the same;
in response to determining that the measurement ID of the first neighboring cell and the measurement ID of the second neighboring cell are the same:
monitoring a current data throughput of an ongoing service,
determining a first offset and a second offset based on the current data throughput, wherein the second offset is greater than the first offset,
applying the first offset to a measurement quantity threshold for the first neighboring cell,
applying the second offset to a measurement quantity threshold for the second neighboring cell,
transmitting a first measurement report for the first neighboring cell when reaching the measurement quantity threshold with the first offset, and
transmitting a second measurement report for the second neighboring cell when reaching the measurement quantity threshold with the second offset; and
in response to determining that the measurement ID of the first neighboring cell and the measurement ID of the second neighboring cell are different:
monitoring a required data rate of a current service,
determining a priority offset value inversely proportional to the required data rate,
applying the priority offset value to a measurement quantity threshold of the first neighboring cell when the required data rate is greater than a predetermined threshold, and
transmitting a measurement report of the first neighboring cell prior to a measurement report of the second neighboring cell based on the applied priority offset value.
