Description
The present invention relates to a multi-party calling technique over a network.
With the increasing number of terminals such as smart phones and tablets using wireless networks globally, MoIP (Multimedia over IP) services using mobile communication networks such as 3G and LTE networks and wireless Internet networks (WiFi networks) are also expanding.
A method of providing MoIP service over a network can be broadly classified into a peer-to-peer (P2P) scheme and a server relay scheme. The peer-to-peer scheme provides a MoIP service through a direct connection between terminals, and is mainly used for one-to-one voice / video calls. The server relaying method is a method in which each terminal connects to a separate server such as an MCU (Multipoint Conference Unit), and mixes voice and video of participants from a connected server, and is used mainly for the conference call of three or more participants.
As described above, in the MoIP service, the one-to-one call and the multi-party call differ in the manner of providing the service, and the protocols used for providing the service are also different. Therefore, when the terminal performing the one-to-one call tries to switch the one-to-one call to the multi-user call by adding the user, the connection is disconnected in the process of terminating the existing one-to-one connection and generating a separate multi- Accordingly, there is a need for a seamless switching method that minimizes connection disconnection when switching a one-to-one call between terminals to a multi-user call.
Embodiments of the present invention are intended to minimize the disconnection of a connection that may occur when converting a one-to-one call between terminals into a multi-user call.

A method for a multi-party call according to another embodiment of the present invention is a method for converting a one-to-one call into a multi-party call while a first terminal performs a one-to-one call with a second terminal, And switching the one-to-one call with the first terminal to the multi-user call according to the multi-user call conversion request at the second terminal.
A multiparty call terminal according to an embodiment of the present invention is a terminal including a memory for storing a program code and one or more processors for executing the program code, The method comprising the steps of opening a conference room for a multi-party call in order to convert the one-to-one call into a multi-party call, transmitting a multi-user call conversion request to the other terminal, and receiving a response to the multi- The call is switched from the one-to-one call with the counterpart terminal to the multi-party call.
A multiparty call terminal according to another embodiment of the present invention is a terminal including a memory for storing a program code and one or more processors for executing the program code, Receiving a multi-user call conversion request from the counterpart terminal in order to convert the one-to-one call into a multi-party call during the execution of the multi-party call; and switching the one-to- . ≪ / RTI >
According to the embodiments of the present invention, when switching a one-to-one call between terminals to a multi-user call, a conference room for multi-party calling is opened before the end of the one-to-one call to minimize disconnection of the user can do.
In addition, according to the embodiments of the present invention, in the process of converting a one-to-one call between terminals into a multi-user call, information necessary for multi-terminal connection between terminals is transmitted through a conventional one-to-one communication channel, There is an advantage that the multi-connection can be efficiently performed.
