When received, priority related to measurement of the quality of the signal transmitted through the second frequency band can be maintained.

When setting priorities, the communication processor 620 may maintain other parameters related to measuring the quality of signals transmitted through the second frequency band. However, the communication processor 620 may change some other parameters related to measuring the quality of the signal transmitted through the second frequency band, depending on the design.

The communication processor 620 may measure the quality of a signal transmitted through the second frequency band based on the set priority.

According to one example, the communication processor 620 determines that the signal quality measurement result is a specified condition (e.g., the signal quality is above (or exceeds) a preset value (threshold), and the preset value is set to the electronic device. Based on confirmation that it is pre-stored in (600) or received through the first node (510), a signal in the second frequency band is broadcast (or is the subject of quality measurement). A connection (e.g., cell reselection) may be performed with a node (e.g., the second node 520).

The communication processor 620 is a second node capable of transmitting or receiving data through a second frequency band of the second cellular communication while the electronic device 600 is in an idle state of the second cellular communication. Second system information (system information block) broadcast by 520 may be received. The idle state is a state in which, after the electronic device 600 and the second node 520 are connected, the connection with the second node 520 is disconnected due to various reasons (e.g., no data to transmit or receive). It can mean. For example, the second frequency band may be a frequency band named B20, but the second frequency band according to various embodiments of the present invention may include various frequency bands as well as B20.

SIB 24 is an identifier of a node supporting the first cellular communication (e.g., the third node 530), a frequency band used by the node supporting the first cellular communication (e.g., the first frequency band), and/or a third node 530. 1 May include physical identification information (PCI) of a node supporting cellular communication.

The second system information may include not only SIB 24 but also various system information (eg, SIB 1). SIB 1 may include business information of the second node 520 or information required when performing access (or random access (RA)) to the second node 520. The communication processor 620 may perform synchronization with the second node 520 based on SIB 1 and receive various system information including SIB 24 from the second node 520.

However, the communication processor 620 may perform the operation of measuring the quality of a signal transmitted through a frequency band other than the first frequency band. This is because, when performing a quality measurement operation in an idle state of the second cellular communication, cell reselection can be performed with the third node 530 based on the measurement result. However, the communication processor 620, when the quality of the signal transmitted by the second node 520 satisfies a specified condition (e.g., a condition where the quality of the signal transmitted by the second node 520 is less than or equal to a specified value), Cell reselection may be performed using the third node 530.

Based on confirmation that the conditions are satisfied, a measurement report including the quality of the signal broadcast by the third node 530 may be transmitted to the second node 520 or the cellular network 500.

The second node 520 or the cellular network 500 that has received the measurement report issues a handover command to the third node 530 according to the quality of the signal broadcast by the third node 530 included in the measurement report.
