Abstract

PURPOSE:To avoid the lowering of working rate of a device owing to mischievous calling, mistaken calling and so on by executing the history control of invalid incoming by call originating terminal number and executing incoming refusing automatically when the invalid incoming more than a fixed number of times is generated from the same terminal number. CONSTITUTION:The conditions setting to discriminate as invalid calling is inputted from an operating display part 2 in advance first. Thus, it is set in a setting recording part 8 by a device control part 1. An incoming starting discriminating part 13 refers to the invalid incoming history of a call originating terminal number in a history storing part 12 and refers to present time and the setting conditions from a timer part 7 and the setting storing part 8 respectively, counts the number of time of invalid incoming generated within a fixed time (one hour) and compares it with the number of times of setting (twice). Since the number of times of the invalid incoming is 0 at first, an incoming starting indication is outputted. The device control part 1 transmits communication capacity to a circuit through an ISDN network interface part 9 by the incoming starting indication and receives a message when response exists and disconnects a circuit as the invalid incoming when the response does not exist for constant time.

[Industrial application field]

The present invention relates to improvements in facsimile machines.

A Group 3 standard (03 standard) facsimile machine (hereinafter referred to as a 03 machine) connected to an 15DN cable will be able to immediately remove the call even if there is a prank call or a wrong call if the identifier of the calling terminal is a telephone or a 03 machine. It receives the signal and sends out a receiving side capability signal for a certain period of time.

Therefore, if these invalid calls are repeated frequently, the operating rate of the device will decrease, and countermeasures are required.

[Prior Art and Problems to be Solved by the Invention] FIG. 4 is a flowchart of incoming call processing for the 03 machine.

After the G3 standard receiving facsimile device connects the line, it sends out the called terminal identification signal CHD, and thereafter, as shown in Figure 4, the communication capability of the receiving side is determined by the digital identification signal DI.
S, etc., are used to repeatedly send the message until there is a response from the caller, and if there is no response after a certain period of time, the line is disconnected.

Therefore, if there are frequent wrong calls or prank calls, the system will be disabled for a certain period of time each time.
Equipment availability decreases.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a facsimile apparatus that determines invalid calls and rejects activation of incoming calls.

Reference numeral 10 denotes a calling terminal number identification unit that identifies the calling terminal number notified from the 15DN network at the time of a call setup request.

Reference numeral 11 denotes an invalid call history management unit that manages and records invalid call history for each calling terminal number.

Reference numeral 13 denotes an incoming call activation determination unit which, when receiving an activation request from the 15DN network, refers to the invalid incoming call history of the originating terminal number identified by the originating terminal number identification unit 10, and if the number of invalid incoming calls satisfies a predetermined condition, The call is determined to be invalid and the incoming call is rejected.

[For production]

The originating terminal number identification unit 10 identifies the originating terminal number notified from the I5DN network at the time of a call setup request.

If the incoming call is activated in response to this call setting request and the call is determined to be an invalid incoming call, the invalid incoming call history management unit 11 records the history, such as the time of occurrence, for each calling terminal number.

On the other hand, upon receiving the call setup request signal, the incoming call activation determination unit 13 refers to the invalid incoming call history for the notified calling terminal number, and if the number of invalid incoming calls satisfies a predetermined condition, for example, If the number of calls exceeds a predetermined number within the time, it is determined to be invalid and the incoming call activation is rejected (for example, the call setting request is ignored).

As mentioned above, in the 15DN network, the originating terminal number is notified in the activation request at the time of call setup, and by using this to manage the history of invalid calls for each originating terminal number, it is possible to learn and memorize invalid calls. It is possible to refuse incoming call activation for frequent calls, slow calls, prank calls, etc.

Note that operations can be made easier by outputting the invalid call history and clearing it for each calling terminal number through operator operations.
