Abstract
A method and an apparatus for performing message communication accurately at high rate even when the communication line is busy. When the communication line between the message transmitting side and the message receiving side connected with an ISDN network is busy, the call between the message transmitting side and the message receiving side is temporarily interrupted and then a message is transmitted automatically from the message transmitting side to the message receiving side by using call setting information where a transmission message is set in a subaddress.
Claims30
A message communication method, which comprises a first telecommunications terminal and a second telecommunications terminal connected to the first telecommunications terminal via an integrated services digital network, and which communicates a predetermined message between the first telecommunications terminal and the second telecommunications terminal, characterized in that the method comprises:
- a step of disconnecting once a call between the first telecommunications terminal and the second telecommunications terminal when the call is in progress between the first telecommunications terminal and the second telecommunications terminal via the integrated service digital network;
- a step of attaching a desired message to call setting information transmitted from the first telecommunications terminal or the second telecommunications terminal, which becomes a message transmitting terminal, in order to reconnect the call between the first telecommunications terminal and the second telecommunications terminal after disconnecting the call between the first telecommunications terminal and the second telecommunications terminal;
- and
- a step of performing a message reception by the first telecommunications terminal or the second telecommunications terminal, which becomes a message receiving terminal, by extracting the desired message attached to the call setting information.
A message communication apparatus, which comprises a first telecommunications terminal;
- and a second telecommunications terminal connected to the first telecommunications terminal via an integrated service digital network, and which communicates a predetermined message between the first telecommunications terminal and the second telecommunications terminal, characterized in that the message communication apparatus comprises:
- call disconnecting means for disconnecting once a call between the first telecommunications terminal and the second telecommunications terminal for communicating a desired message when a call is in progress between the first telecommunications terminal and the second telecommunications terminal via the integrated services digital network;
- message transmitting means for performing a message transmission by attaching the desired message to call setting information transmitted from the first telecommunications terminal or the second telecommunications terminal, which becomes the message transmitting terminal in order to reconnect the call between the first telecommunications terminal and the second telecommunications terminal after disconnecting the call between the first telecommunications terminal and the second telecommunication terminal;
- and
- message receiving means for performing a message reception by extracting the desired message attached to the call setting information at the first telecommunications terminal or the second telecommunications terminal, which becomes the message receiving terminal.
A message transmitting terminal connected to an integrated services digital network, characterized in that the message transmitting terminal comprises:
- call disconnecting means for disconnecting once a call with a message receiving terminal in order to transmit a desired message during the call with the message receiving terminal;
- and
- message transmitting means for performing a message transmission by attaching the desired message to call setting information transmitted for reconnecting with the message receiving terminal after disconnecting the call by the call disconnecting means.
A message receiving terminal connected to an integrated services digital network, characterized in that the message receiving terminal comprises:
- call disconnecting means for disconnecting once a call with a message transmitting terminal in order to receive a desired message during the call with the message transmitting terminal;
- and
- message receiving means for extracting the desired message attached to call setting information sent from the message transmitting terminal for reconnection with the message receiving terminal after disconnecting the call by the call disconnecting means.
