The third electronic device 103 can transmit the conference invitation request message to the first electronic device 101 and switch the communication mode from the short-range wireless communication mode to the cellular communication mode when the status abnormality of the short-range wireless communication occurs. For example, the conference call invitation request message may be a message requesting the invitation of the third electronic device 103 to the call between the first electronic device 101 and the second electronic device 102. For example, the conference call invite request message may include unique identification information (e.g., a telephone number, a unique identification number of a Bluetooth module, or a short range wireless communication module of a third electronic device 103 Address).

According to one embodiment, when the conference invitation request message is received, the first electronic device 101 may originate (703) a call to the third electronic device 103 via the base station 510 using cellular communication. For example, when a conference invite message is received from the third electronic device 103, the first electronic device 101 may send a conference call request message to the base station 510. [ For example, the conference call request message may be a message requesting to add a call between the first electronic device 101 and the third electronic device 103 to the currently connected call. For example, the conference call request message may include the unique identification information of the third electronic device 103.

For example, when a conference call request message is received, the base station 510 may transmit a call connection request message to the third electronic device 103 using cellular communication. For example, the call connection request message may be a message requesting a call connection between the first electronic device 101 and the third electronic device 103.

According to one embodiment, when a call connection request message is received, the third electronic device 103 may join (705) the conference call by connecting the call between the first electronic device 101 and the third electronic device 103 via the base station 510 .

For example, the message may be output using audio, pop-up windows, vibration, or a combination thereof.

The third electronic device 103 may generate a call connection response message based on the response received from the user and transmit the call connection response message to the base station 510. For example, if the received response is a rejection of a call connection, the third electronic device 103 may send a call connection response message to the base station 510 that includes information indicating rejection of the call connection. In another example, if the received response is an acceptance of a call connection, the third electronic device 103 may send a call connection response message to the base station 510 that includes information indicating the acceptance of the call connection.

For example, when a call connection response message is received, the base station 510 may connect a call between the first electronic device 101 and the third electronic device 103 based on the call connection response message. For example, if the call connection response message includes information indicating rejection of a call connection, the base station 510 may not connect a call between the first electronic device 101 and the third electronic device 103. In another example, if the call connection response message includes information indicating acceptance of a call connection, the base station 510 may connect a call between the first electronic device 101 and the third electronic device 103. [

For example, when a call is established between the first electronic device 101 and the third electronic device 103, the first electronic device 101 may generate a call merge request message and send it to the base station 510. For example, the call merging request message may be a message requesting to merge a call between the first electronic device 101 and the second electronic device 102 and a call between the first electronic device 101 and the third electronic device 103. For example, when a call merge request message is received, the base station 510 may merge a call between the first electronic device 101 and the second electronic device 102 and a call between the first electronic device 101 and the third electronic device 103.

For example, if the first electronic device 101 requests a call from the third electronic device 103 to the base station 510 using cellular communication, the cellular communication module of the third electronic device 103 may be powered off . Thus, when the cellular communication module is powered off, the third electronic device 103 will not be able to receive the call from the base station 510. To prevent this, the first electronic device 101 may send a communication module activation request message requesting the third electronic device 103 to power on the cellular communication module using short range communication. For example, the first electronic device 101 may request a call origination after transmitting a communication module activation request message. As another example, the first electronic device 101 may transmit a communication module activation request message if a response to the call origination is not received within a predetermined time after requesting the call origination.
