Abstract: An electronic device is provided. The electronic device in an embodiment includes a subscriber identity module (SIM) and at least one processor, comprising processing circuitry, electrically connected to the SIM. At least one processor, individually and/or collectively, is configured to: detect a second cell based on a movement of the electronic device in a first cell of a network of a telecommunications carrier of the SIM, recognize a 5G shared network based on at least a portion of system information of the second cell, determine whether the electronic device requires a 5G service in the 5G shared network, based on determining that the electronic device requires a service other than the 5G service, control the electronic device to be connected to a base station of the first cell, and based on determining that the electronic device requires the 5G service, control the electronic device to be connected to a base station of the 5G shared network.

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: An electronic device may include at least one communication processor and an application processor. The at least one communication processor is configured to: receive first system information including information on whether at least one node supporting first cellular communication supports DC or second system information including information on a node which is adjacent to the at least one node and supports second cellular communication, from the at least one node via the first cellular communication; update, based on the first or second system information, a database which includes information indicating whether the at least one node supports the DC and information indicating whether the node adjacent to the at least one node supports the second cellular communication; determine, based on the updated database, a searching order of at least one node included in the updated database; and search for a node to be registered, based on the determined searching order.
