Title: Two-way communication control method using conference speech path
Inventor: JUNG SEO YEONG
IPC: H04M3/56
Filed: 2002-12-21
Abstract: PURPOSE: A bi-directional communication control method using a conference speech path is provided to allow a system user to perform a bi-directional broadcast function with a specific user or multiple users by using a normal broadcast dedicated call line. CONSTITUTION: When a system user inputs a certain command language, a central processor analyzes the inputted command language to check whether a system is in a broadcast service mode(S40). When the system user inputs a broadcast select command language, the system is switched to a broadcast service mode. When the system user designates a specific user or multiple specific users(S41), the central processor detects signals received from input/output units of designated users and checks whether a previously connected broadcast dedicated call line is normal(S42). If the previously connected broadcast call line is normal, bi-directional broadcast function is performed(S43).
