摘要： An example electronic device includes a communication processor for establishing a cellular communication with a first node supporting a first frequency band or a second node supporting a second frequency band; an application processor; and memory. The memory can store instructions which, when executed, control the communication processor such that: the communication processor confirms a service type performed by the cellular communication; the application processor confirms whether or not the state of the electronic device satisfies a predetermined condition set differently in accordance with the service type; and the application processor blocks a connection with the second node and/or releases the connection with the second node, in response to confirming that the state of the electronic device does not satisfy the predetermined condition.
