The present invention relates to a method for controlling a call through transmitting and receiving call metadata between a transmitter terminal and a receiver terminal in a wireless communication system. The method includes: a step in which the transmitter terminal transmits an access information to the receiver terminal through a call channel; a step in which the transmitter terminal transmits access information through a relay server; a step in which the receiver terminal receiving the call signal extracts the access information of the transmitter terminal from the relay server; and a step in which the receiver terminal establishes a metadata channel for the transmission and reception of the call metadata with the transmitter terminal by using the extracted access information. Accordingly, the present invention enables various expressions for the metadata of calls in order to reduce unnecessary calls by obtaining sufficient information for connecting the calls, thereby increasing the call connection efficiency. |
