According to various embodiments of the disclosure, an operating method of an electronic device 101 may include connecting to a first communication network among a plurality of communication networks supportable by the electronic device 101; determining whether to perform a handover to a second communication network, based on whether a display device 160 is activated and a data throughput, in a state of connection to the first communication network; and performing a handover to the second communication network when it is determined to perform the handover to the second communication network.
The determining whether to perform the handover may include determining to perform the handover to the second communication network when the display device 160 is deactivated and the data throughput is lower than a reference throughput.
The reference throughput may be set based on a use pattern of a user with respect to the electronic device 101, and the use pattern may be set based on at least one of a data usage per user collected for a reference time period, the data throughput, a use frequency of an application program, or an application program use time.
The determining whether to perform the handover may include determining to perform the handover to the second communication network when the display device 160 is deactivated and an application processor associated with the first communication network is not driven; and determining to perform the handover to the second communication network when the display device 160 is deactivated, the application processor associated with the first communication network is driven, and the data throughput is lower than the reference throughput
