The present invention discloses a method for controlling a call between the exchange of call metadata between a transmission terminal and a reception terminal in a wireless communication network. The method includes: a step in which the transmission terminal transmits a call signal to a reception terminal through a call channel; a step in which the transmission terminal transmits access information to the reception terminal through a relay server; a step in which the reception terminal receiving the call signal extracts the access information of the transmission terminal through the relay server; and a step in which the reception terminal uses the extracted access information to establish a metadata channel to exchange the call metadata with the transmission terminal. Accordingly, the present invention enables various expressions of the call metadata to obtain enough call connection information to reduce unnecessary calls and increase the call connection efficiency. |
