Electronic device to support dual connectivity and operating method thereof

An electronic device comprising:

• at least one communication processor configured to support a first network communication and a second network communication, and
• a memory configured to store information about at least one first band supporting dual connectivity for the first network communication and the second network communication among a plurality of bands which correspond to the first network communication supported by the electronic device,
• wherein the at least one communication processor is further configured to:
• connect to a first cell supporting the first network communication,
• while being connected to the first cell, perform a measurement on at least some of the at least one first band among the plurality of bands, wherein a measurement on a remaining band except for the at least one first band among the plurality of bands is not performed,
• perform at least some of a handover procedure based on a measurement result for the at least some of the at least one first band,
• perform a measurement on the first cell,
• identify whether a measurement result for the first cell satisfies a first condition, and
• based on identifying that the first condition is satisfied, determine to perform a measurement on the at least one first band among the plurality of bands and not to perform the measurement on the remaining band except for the at least one first band, and
• wherein, as at least part of identifying whether the measurement result for the first cell satisfies the first condition, the at least one communication processor is configured to identify whether the measurement result for the first cell is greater than a sum of a threshold value and a value set for a hysteresis operation.
