Abstract: According to various embodiments, an electronic device includes at least one processor. The at least one processor is configured to: after establishing an RRC connection with a first cell of a first RAT, confirm the occurrence of an event associated with the release of the RRC connection with the first cell; camp on to a second cell of a second RAT different from the first RAT in response to the confirmation of the occurrence of the event; initiate a timer, defined in an NAS, on the basis of a failure to register to a core network corresponding to the second RAT; and perform one of a scan associated with the first RAT or a scan associated with a RAT according to a preset priority, on the basis of the initiation of the timer, according to whether a service performed while connected to the first cell is an IMS call service.

Abstract: According to various embodiments, an electronic device may include at least one processor and a sensor module, wherein the at least one processor is configured to, while a first connection to a first network is established based on a first RAT, identify that the electronic device is in over-temperature state based on sensing data from the sensor module, based on identifying that the electronic device is in the over-temperature state, identify whether a specified application is executed or not, based on identifying that the specified application is executed, release the first connection without receiving a connection release message from the first network, after the first connection is released, perform a scan associated with a second RAT different from the first RAT, based on a result of the scan, establish a second connection with a second network different from the first network based on the second RAT. An electronic device comprising at least one processor, wherein the at least one processor is configured to, identify an over-temperature state in a state of being connected to a first RAT, based on the identification of the over-temperature state, identify whether a connection for the first RAT is maintainable, based on identifying that the connection for the first RAT is maintainable, perform at least one first operation corresponding to the over-temperature state while maintaining the connection for the first RAT, and based on identifying that the connection for the first RAT is not maintainable, perform at least one second operation for establishing. Various other embodiments are possible.
