Abstract

According to one embodiment, the electronic device may include at least one processor and a memory for storing instructions. When the instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to connect to a first cell provided by a first satellite. When the instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to enter an idle state based on the condition for entering an idle state being satisfied after connecting to the first cell. When the instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to check for the occurrence of an event to resume communication in the idle state. When the instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to compare the remaining time of provision of the first cell provided by the first satellite with the estimated time of service setup corresponding to the event, based on the confirmation of the occurrence of the event. When the above instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to perform a cell search based on confirming, according to the comparison result, that the remaining time of provision of the first cell by the first satellite is less than the estimated time of service setup corresponding to the event. When the above instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to connect to the second cell based on confirming, according to the cell search result, that the remaining time of provision of the second cell provided by a second satellite different from the first satellite is greater than the estimated time of service setup corresponding to the event. When the above instructions are executed individually or collectively by the at least one processor, they may cause the electronic device to perform a service corresponding to the event while connected to the second cell. Various other embodiments are possible.

Description

Electronic device supporting non-terrestrial network communication and method for operating thereof One embodiment of the present disclosure relates to an electronic device that supports non-terrestrial network communication and a method of operating the same. Recently, electronic devices supporting non-terrestrial network communication (e.g., satellite communication) are being actively introduced. As an example, electronic devices can communicate with a satellite of an existing satellite communication provider by utilizing that provider's frequencies and communication methods. As another example, electronic devices can communicate with a satellite using cellular frequencies based on the LTE (long-term evolution) standard (or 5G standard). As yet another example, electronic devices can communicate with a satellite based on the 5G NTN (non-terrestrial networks) standard. For example, if an electronic device communicates with a non-terrestrial network based on LTE standards, some of the frequencies defined in LTE standards may be allocated to non-terrestrial communication. The electronic device may perform satellite communication using the protocol stack used in terrestrial communication, and an additional protocol stack for non-terrestrial communication may not be required. The electronic device may perform communication without distinguishing between non-terrestrial and terrestrial communication. For example, the electronic device may perform operations to perform a cell scan, camp on to a cell satisfying cell selection criteria, and access a network (e.g., may include camp on, random access (RA) procedures, connection establishment procedures, and/or attach (or registration)). The electronic device may perform operations to camp on to a cell satisfying cell selection criteria and access a network without distinguishing between non-terrestrial and terrestrial communication. Accordingly, the electronic device can prepare to perform non-terrestrial communication in substantially the same manner as terrestrial communication.
