The present invention relates to a video call in a W-CDMA network, and more particularly, to a service for adding a speaker in a multi-party video call.

In the W-CDMA network, the circuit-switched 3G.324M standard defined in 3GPP (3rd Generation Partnership Project) is applied as a protocol for video calling. 3G.324M is an extension of H.324 defined by the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T), which adds AMR audio codec and MPEG4 video codec to H.324.

Here, since the circuit switching method is applied, when a video call is performed between mobile communication terminals in a W-CDMA network, a dedicated channel is allocated between each mobile communication terminal and maintained until the video call ends.

On the other hand, a mobile communication terminal in a W-CDMA network may communicate with a video call supporting terminal through a packet-switched network such as an Internet Protocol (IP) network. In this case, a circuit-switching network may be used. Apparatuses for converting the data format required for a switched network to the data format required for a packet-switched network and a communication protocol for controlling the converting apparatus are applied.

Currently, MGW (Media GateWay) is used as the conversion device, and Megaco or H.248, which is enhanced with MGCP (Media Gateway Control Protocol), is used as the protocol.

In using such a video call service, when a new video call connection is requested from a third caller while a video call is in progress, the third caller simply switches the caller to a call waiting state or the receiver manually enters the call. Only the method of setting the access permission or the like has been proposed.

In order to solve the conventional problems as described above, the present invention proposes a method for providing a service for allowing existing video call participants to conveniently select whether to allow access when a new video call connection is requested during a multi-party video call.
