Electronic device transmitting and/or receiving packet through network slice and method for operating the same

According to various embodiments, an electronic device may comprise: at least one processor and at least one communication processor. The at least one processor may be configured to: obtain a user equipment (UE) route selection policy (URSP) rule including a first traffic descriptor including a first IP address and a first route selection descriptor corresponding to the first traffic descriptor and request the at least one communication processor to establish a first PDU session corresponding to the first route selection descriptor. The at least one communication processor may be configured to: establish the first PDU session corresponding to the first route selection descriptor in response to the request to establish the first PDU session. A first network interface corresponding to the first PDU session may be established between the at least one communication processor and the at least one processor. The at least one processor may be configured to identify transmission data from an application executed by the at least one processor, request the at least one communication processor to transmit a first transmission packet including a first source IP address corresponding to the first network interface and the transmission data, through the first network interface, based on a destination IP address corresponding to the transmission data corresponding to the first IP address, and request the at least one communication processor to transmit a second transmission packet including a second source IP address corresponding to a second network interface, different from the first network interface, and the transmission data, through the second network interface, based on the destination IP address corresponding to the transmission data not corresponding to the first IP address.
