DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a communication device such as a facsimile machine, and particularly to a re-call control device thereof.

(Prior Art) In conventional communication devices such as facsimile machines, when a call cannot be connected due to a busy state on the network side, a busy state on the terminal side, or a failure, etc.,
Regardless of the reason (cause), only the failure to connect the call is detected, and the call is made again after a certain period of time.

ても呼が成立する確率が高い。
Generally, the call loss rate caused by the network side is set to 0.1 or less based on the amount of communication traffic, and even if a call is made again in a short time, the probability of establishing a call with the other party's device is very high. In addition, in the case of a call loss due to the other party's terminal being in local operation, depending on the processing content on the receiving terminal side (for example, the operator interrupted the local operation, or the device side automatically interrupted the local operation temporarily, etc.), Even if a call is made again in a short period of time, there is a high probability that the call will be established.

これに対して、相手端末が故障中等で長時間呼を受付け

再呼時、呼損を生じる確率が高くなる。
On the other hand, if the other party's terminal does not accept calls for a long time due to a malfunction or the like, there is a high probability that a call will be lost when a call is made again unless a certain amount of time is left.

As described above, in the conventional method, always re-calling after a certain period of time cannot be said to be optimal call origination control considering that incoming calls from other devices cannot be accepted at the time of origination.

(Problems to be Solved by the Invention) The present invention solves the problem in a communication device such as a facsimile machine when a call cannot be connected due to circumstances of the other party's device or network.
It is an object of the present invention to eliminate the drawbacks of conventional devices that control re-calls after a certain period of time regardless of the reason for the call loss.
