When there is no data transmitted and received through the first communication network (e.g., No in operation 1501) or transmission and reception of the data through the first communication network is completed (e.g., Yes in operation 1503), the electronic device (e.g., the processor 120 and/or the wireless communication module 192) may restrict a data channel request to the first communication network in operation 1505. In this case, a communication channel (control channel and data channel) with the second communication network may be maintained. In one example, restriction of the data channel request may include a state in which the electronic device is configured not to transmit a request message for establishing a data channel to the first communication network when data associated with the electronic device 101 occurs in case that the data channel with the first communication network is disconnected. The electronic device 101 may transmit and receive data associated with the electronic device 101 through the communication channel with the second communication network.
In the following embodiments, individual operations may be performed sequentially but are not necessarily performed sequentially. For example, the order of individual operations may be changed, and at least two operations may be performed in parallel. Here, the electronic device may be the electronic device 101 of
