US 5,333,134 A · Connection hold control system

Abstract

A connection hold control system is adapted to a data communication system in which a data communication is alternately made between a first terminal and a second terminal and between the first terminal and a third terminal, where each of the first through third terminals is coupled to a communication network via a terminal adapter. The connection hold control system includes a hold part, provided within a first terminal adapter which is coupled to the first terminal, for holding a first channel which connects the first and second terminals via the communication network and the terminal adapters after a data communication from the first terminal to the second terminal ends, and a connect part, provided within the first terminal adapter, for connecting the first and second terminals via the first channel if a data communication from the first terminal to the third terminal via a second channel ends within a predetermined time after the data communication from the first terminal to the second terminal ends.

Dependent claims

A connection hold control system in an interface between a first terminal and a communication network providing communication channels for data communication to a second terminal and a third terminal, said connection hold control system comprising:

hold means for delaying release of a first channel connecting the first and second terminals via the communication network after completion of data communication from the first terminal to the second terminal;
and
connect means for connecting the first and second terminals via the first channel if data communication from the first terminal to the third terminal via a second channel ends within a predetermined time after the data communication from the first terminal to the second terminal ends.

A connection hold control method adapted to a data communication system in which data communication is alternately made between a first terminal and a second terminal and between the first terminal and a third terminal, each of the first, second and third terminals being coupled to a communication network via first, second and third terminal adapters, respectively, said connection hold control method comprising the steps of:

(a) holding, within the first terminal adapter, a first channel which connects the first and second terminals via the communication network and the first and second terminal adapters after completion of data communication from the first terminal to the second terminal;
and
(b) connecting, within the first terminal adapter, the first and second terminals via the first channel if data communication from the first terminal to the third terminal via a second channel ends within a predetermined time after completion of the data communication from the first terminal to the second terminal ends.
