Embodiment Construction

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION The preferred embodiment of the invention is shown in the accompanying drawings.

[0023] image 3 is a flow chart showing the multi-party call method according to the present invention. As shown, when the first and second users are communicating (S310), the third user calls the first user (S320). After being notified of the third user's call, the first user puts the second user on hold (S330). The first user then answers the call from the third user (S340) and sends a multi-party call join command to the network using device messages, eg (S350). In addition, when the multi-party call joining command is sent, a flag is set in the mobile terminal of the first user, thereby skipping the audio channel closing operation involving the established call with the second user (S360).

[0024] Subsequently, when the first user's mobile terminal receives an MPTY OK device message from the network, indicating tha...

Abstract

A multiparty calling method, which includes initiating a multiparty call between at least a first, second and third terminal, and setting a flag in the first terminal to inform a processor of the first terminal to skip a process of closing an existing communication path between the first terminal and the second terminal, when the first terminal is disconnected with the third terminal. Further, the set flag is released when the multiparty call between the at least first, second and third terminals has been established for a predetermined time period. In addition, the first terminal preferably sets the flag when the multiparty call join command is transmitted to the network.

Description

(1) Technical field [0001] The present invention relates to a multi-party calling method and a corresponding mobile communication terminal, and more particularly to a multi-party calling method and a corresponding terminal for preventing one party from being disconnected when the other party is disconnected due to, for example, a network error. (2) Background technology [0002] Common communication networks, such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), and Universal Mobile Telecommunications System (UMTS) networks, allow users to use a call channel to communicate simultaneously with multiparty call services supported by the corresponding network. Many other people have conversations. This multiparty calling service is also known as multiparty calling (eg, MPTY calling) or conference calling. [0003] More specifically, figure 1 is a flowchart showing a related art multi-party calling method between three users. As shown, a f...
