Description

How to handle facsimile automatic transmission service using facsimile intelligent information providing system {THE PROVISION METHOD FOR FAX AUTOMATED-MAIL SERVICE USING IP WHEN FAX DEVICE IS HOOK OFF}

The present invention automatically stores FAX data in an IP system when an incoming fax machine is busy using announcement and facsimile (FAX) resources among special resources of an intelligent information providing system (IP). The present invention relates to a method for processing a facsimile automatic transmission service that can automatically transmit fax data to a called party when an incoming fax machine is idle.

In the related art, when a sender wants to send a fax, the sender can only transmit fax data when the called fax number is idle after dialing the called fax number. FAX reception from the sender was not possible. In other words, when the receiving FAX device is receiving the FAX data, the second other sender has to wait for the state of the receiving FAX device to be idle and then transmit the FAX data when the receiving FAX device is idle.

In other words, conventionally, after dialing an incoming fax number for fax transmission, FAX data is transmitted remotely only when there is a response from the called party. However, when the called FAX device is busy, the sender waits until the called party's FAX device becomes idle and then dials again to transmit FAX data to the called party. Therefore, when the called party is busy, there is a troublesome problem that the sender has to retry several times and transmit the FAX data.

In order to solve this problem, there is a method of transmitting FAX data by storing the FAX data and the called number in the calling FAX device when the called FAX device is busy and redialing until the called FAX device becomes idle.

However, the method of transmitting the fax data by storing the fax data and the called number in the originating fax machine and redialing until the called fax machine becomes idle is performed by a device capable of storing the fax data in the originating fax machine. A device capable of dialing a FAX device should be added, and there is a problem of causing waste of communication network resources from the originating FAX device to the destination FAX device by redialing at the originating FAX device until the incoming FAX device is idle. In addition, there is a problem of causing a delay in transmission of the fax data by redialing at the originating fax machine and checking an idle state of the incoming fax machine.

Therefore, the FAX data is automatically stored in the intelligent information providing system when the FAX device is busy by using the FAX resource and the announcement broadcasting resource among the special information of the intelligent information providing system of the next generation intelligent network, and the incoming FAX device is idle. If it is automatically recognized by the communication network, the FAX automatic transmission service processing method that can immediately transmit the FAX data is required.

According to the present invention proposed to meet the above demand, the FAX data is automatically stored when the FAX device is busy using the FAX and the announcement broadcasting resource among the special resources of the intelligent information providing system (IP). It is an object of the present invention to provide a method for processing a FAX autotransmission service for automatically transmitting FAX data when a FAX device is idle.

The network matching unit 531 operates in the SRS 53 and is in charge of communicating with SCP 10 and the SSP 40, which are other network elements in the intelligent network, through the SS No. 7 link, and the service user through the voice channel. It has a number of Integrated Services Digital Network / Public Switching Telephone Network (ISDN / PSTN) interfaces for exchanging information.

When the service controller 512, 532, 541 receives a request for resource use from the service logic program of the SCP 10 through the network matching unit 531, it allocates a special resource held by the IP 50 to the service user to perform the intelligent network service. Perform user interaction functions to collect additional information required or to provide information to service consumers. At this time, the database is searched according to the service logic program of the IP 50 to provide a service by managing a procedure of analyzing, allocating, initializing, occupying, restoring, and rejecting a state of a corresponding resource of the resource controllers 534 and 543.

The resource control unit 534, 543 is a service control unit 512, 532, 541 to provide the resource functions such as announcement broadcasting, DTMF digit collection, voice recognition, voice synthesis, voice recording, and FAX, which are basic units of service that users can actually access the IP 50. To the service user upon request. In addition, various types of information (ie, voice, data, and video) in the IP 50 are stored in the disk 55, and information input / output and editing functions are provided therefor.

The service operation management unit 511, 521, 533, 542 is mainly responsible for the operation management, maintenance, and operator matching functions of the system. In addition, it manages the state of hardware, software configuration data, and various resources of the IP 50, and collects various event and traffic data generated during system operation to calculate measurement and statistical data.

In addition, the service operation management unit (511,521,533,542) diagnoses the failure of the system and provides appropriate measures according to the failure level, and performs a test and resource service call tracking function to immediately report the problem to the operator to facilitate problem recovery. Process it. In addition, it provides various Graphic User Interface (GUI) functions between the system and the operator.
