Abstract

A method for supplying a video effect service to a video call and a system are provided to enable an MSC(Mobile Switching Center) to send a video call to a video effect service server so that the server can add video effects to the video call to send the call to the MSC, thus the MSC can send the video call added with the video effects to a receiving mobile communication terminal. A video call connection request signal is received from a transmission mobile communication terminal(S500). Subscriber information is demanded to an HLR(Home Location Register) to confirm whether the transmission terminal is registered in a video effect service(S502,S504). If so, a video call is set with a receiving terminal, and traffic of the video call is routed to a video effect service server to send the video call to the server(S506). The video call added with video effects selected by the transmission terminal is received from the server, and is transmitted to the receiving terminal(S510-S514).
