Filed: 1998-12-01
Abstract: PURPOSE: A due time value setup method in determining the master/slave between terminals is provided to set up a due time value of until receiving an acknowledge signal after transmitting a request signal as an optimum value adaptively in network environment. CONSTITUTION: In requesting the connection to a second H.323 terminal from a first H.323 terminal(300), the first H.323 terminal counts a required time after transmitting a connection request signal(302). The first H.323 terminal judges whether a master acknowledge signal is received successfully(304). The first H.323 terminal stops counting the required time and stores the counted value as a current due time value(306). The first H.323 terminal calculates a difference between the stored current due time value and a previous due time value(308). The first H.323 terminal adds the difference to the current due time value and sets up as a due time value for the next connection(310).
