Method for performing relay communication and electronic device thereof

An electronic device, comprising:

• a first communication circuit configured to establish a communication connection, using a first network;
• a second communication circuit configured to establish a communication connection, using a second network;
• and
• one or more processors connected to the first communication circuit and the second communication circuit,
• wherein the one or more processors are configured to:
• receive an application identifier (AID) list and one or more radio frequency (RF) parameters from a first external electronic device through the second communication circuit,
• update a routing table of the first communication circuit based on the AID list, and
• update an RF parameter of the first communication circuit based on the one or more RF parameters.

A method of performing relay communication in an electronic device, the method comprising:

• receiving near field communication (NFC) control data and relay transaction data for an NFC service from an external electronic device through a first communication circuit of the electronic device;
• acquiring an application identifier (AID) from the transaction data for the NFC service;
• determining a security module corresponding to the AID of one or more security modules of the electronic device;
• transmitting the NFC control data and the transaction data for the NFC service to the security module corresponding to the AID of the one or more security modules of the electronic device through a second communication circuit of the electronic device;
• and
• transmitting a response signal received from the security module corresponding to the AID of the one or more security modules of the electronic device to the external electronic device through the first communication circuit.
