Communication system with auto dialing function and auto dialing method

1 is a block diagram of a general information network subscriber matching device having an automatic dialing function according to an embodiment of the present invention.

2 is a flowchart of call party automatic call control according to an embodiment of the present invention. 2A is a control flowchart in which a called party receives a packet from a calling party and stores the address of the calling party in a local memory. FIG. 2B is a control flowchart in which the called party automatically executes call setup to the address of the calling party stored in the local memory when the called party desires communication with the calling party.

The present invention relates to a digital information network subscriber matching device and method having a redialing function, and more particularly, to a destination address (hereinafter referred to as a sender) of a calling subscriber (hereinafter referred to as a subscriber) with which any subscriber has previously communicated. The present invention relates to a communication system and a control method for automatically calling an address or telephone number.

The current telephone terminal has a redialing function of resending previously transmitted dialing signals by simple key operation to reconnect the communication channel with the other party. The function of such redialing can greatly enhance the user's convenience as the destination address of the called subscriber (hereinafter referred to as a recipient) is long. Therefore, such a function is widely used in a general telephone terminal device because it is possible to quickly and accurately dial the call for the other party. Such a redialing function is also provided in a communication system, for example, a key telephony system which is a small-capacity simple exchange, a private private exchange in the premises. Redialing is becoming more and more necessary due to the complexity and diversity of the addressing system of incoming calls.

Typically, such a redialing function is performed by storing previously dialed digits in a dial buffer and sending out the digits stored in the dial buffer when the redialing key is selected. However, the redialing function according to the prior art has been inconvenient, which is limited only when the dialer has already dialed in order to communicate with a sender, for example, any subscriber. That is, when the sender calls any subscriber, when the receiver desires to communicate with the sender who is the subscriber who has just called and communicated with the receiver, the called party's called number (called a normal telephone number as a destination address) must be dialed one by one. It was.

Such a redialing method causes a problem that is very difficult to be applied as it is in a future communication method, for example, a multimedia communication system. This is because a multimedia communication system using a narrowband integrated services digital network (N-ISDN) or a broadband integrated information digital network (B-ISDN) has a complicated destination address system. This is because the communication with the other party requires connection with the other party with minimal effort.

Therefore, the conventional technique of performing redialing only when there is previously dialed information as described above communicates with the subscriber who was previously connected to the communication channel because the receiver cannot have the address information of the called party. If you want to do this, you need to dial the subscriber number corresponding to the complicated counterpart's address.

The above problem can be solved by using a call control message transmitted and received through a channel for transmitting control packets transmitted and received between ISDs. In the following description, the technical configuration thereof will be described in detail.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

1 is a block diagram of a general information network subscriber matching device having an automatic dialing function according to an embodiment of the present invention. In the above configuration, reference numeral 100 denotes a UNI having an automatic dialing function according to the present invention. The UNI 100 is connected between a communication network 190 (hereinafter referred to as a network) 190 and a subscriber 160 to transmit and receive control packets from the subscriber 160 and the network 190 to form a communication channel. The subscriber 160 generates a control packet and subscriber data for call setup and communicates with the other party through the UNI 100 and the network 190. The network 190 transmits and receives the control packet and data with the UNI 100 and exchanges data through a communication channel with the other party. The network 190 may be a packet-switched public data network (PSPND), which is a switching network for performing data communication by executing packet switching, and N-ISDN, B-ISDN, etc. may be used.

In the above configuration, the UNI 100 records data under the control of the CPU 110, the ROM 120 storing the main operation of the UNI 100, the ROM 120 including the program code for carrying out the present invention, and the control of the CPU 110. A read-only RAM 130, a subscriber matching unit 150 for interfacing control packets and data between the subscriber 160 and the CPU 110, and control data output from the subscriber matching unit 150 to the CPU 110, or A subscriber control packet processing unit 140 for supplying control data output from the CPU 110 to the subscriber matching unit 150, a network matching unit 180 for interfacing the network 190 and the control packets and data of the CPU 110, and extracted from the network matching unit 180. It includes a network control packet processor 170 for transmitting control data to the CPU 110 or the control data output from the CPU 110 to the network matching unit 180. It can control.

The UNI configured as described above receives the call setup control packet from the user, that is, the subscriber 160, transmits the control packet to the network 190, and receives the call setup packet from the network 190 to perform communication processing. It should be noted that in the present invention, only an operation procedure in which the called subscriber (e.g., the receiver) makes the dialing very easily by using the call setup packet from the calling party, that is, the sender, will be described in detail.

2 is a flowchart of call party automatic call control according to an embodiment of the present invention. 2A is a control flowchart in which the called party receives a packet from the calling party and stores the address of the calling party in the local memory. FIG. 2B is a control flowchart in which the called party automatically executes call setup to the address of the calling party stored in the local memory when the called party desires communication with the calling party.

Referring to Figures 1, 2a and 2b described above in detail the operation of the embodiment according to the present invention. First of all, prior to the description of the present invention, an example of a case where a subscriber wants to negotiate with any subscriber connected to the network 190 through the UNI as shown in FIG. 1, for example, the subscriber 160 connected to the UNI 100 will be described. do.

Now, if any subscriber, for example, a calling party (which means a subscriber connected to the network 190 via another UN), dials to communicate with subscriber 160 shown in FIG. The configuration control packet is transmitted through the network 190 to the network matching unit 180 shown in FIG. 1.

The network matching unit 180 receives the control packet and network data transmitted from the network 190 and supplies the same to the CPU 110. At this time, the network control packet processor 170 extracts only the control packet from the network matching unit 180 and notifies the CPU 110 that the control packet is received from the network matching unit 180. In response to the message output from the network control packet processor 170, the CPU 110 receives, via the network matching unit 180, a call setup control packet transmitted from the sender in step 2a of FIG.

The CPU 110 receiving the call setup control packet in step 210 of FIG. 2A searches whether the sender's address (for example, a telephone number as an incoming call information) is included in the control packet received in step 220. If it is determined in step 220 that the sender's address is included, the CPU extracts the sender's address from the control packet received in step 230 and stores the sender's address in the local memory set on the RAM 130 shown in FIG. In step 240, a general communication processing flow is performed. If it is determined that the sender's address is not included in the received control packet as a result of the search in step 220, the CPU 110 performs a general communication processing flow in step 240.

When the call setup control packet corresponding to the incoming call for calling the subscriber 160 is received in the above operation process, the communication channel is stored after storing the sender address included in the call setup control packet in the local memory. To exchange information. Accordingly, it can be seen that each time the subscriber 160 shown in FIG. 1 is called, the address of the counterpart, that is, the telephone number, is automatically stored in the RAM 130 in the UNI 100 controlling the network connection of the subscriber 160. As such, the address of the counterpart stored in the RAM 130 is very useful for automatic dialing, which will be clearly understood by the following description.

Now, the operation in the case where the subscriber 160, which is the called subscriber, wants to communicate with the other party who has communicated with him, will be described with reference to FIG. 2B.

If subscriber 160 wishes to communicate with the other subscriber, for example, the caller who has called itself, and generates a call setup control packet including a redial function request message, it is input to subscriber matching unit 150. The subscriber matching unit 150 transmits the call setup control packet and the subscriber data generated from the subscriber 160 to the subscriber control packet processing unit 140. The control packet processor 140 extracts only the control packet from the signal output from the subscriber matching unit 150 and transmits the control packet to the CPU 110.

At this time, the CPU 110 analyzes a control packet transmitted from the subscriber control packet processing unit 140 and receives a function, for example, a redial function request message, to communicate with the sender to which the subscriber 160 previously communicated. When the redial function request message is received in step 2b of FIG. 310, the CPU 110 determines whether there is an address of a sender stored in a local memory set in an area of the RAM 130 in step 320.

If it is determined in step 2b that the sender's address exists in the local memory in step 320, the CPU 110 accesses the addresses of the counterpart stored in the local memory in step 330 and transmits the address to the subscriber 160 through the subscriber matching unit 150. The subscriber 160 displays the address of the counterpart received through the subscriber matching unit 150 (not shown). The display device may be a monitor of a computer or a liquid crystal display of a digital telephone. ]. When the user selects one of the addresses of the counterpart stored in the local memory through the display device of the subscriber 160 in step 340 of FIG. 2B, the selection information is transmitted to the CPU through the subscriber matching unit 150 and the subscriber packet processing unit 140. Is entered.

At this time, the CPU 110 accesses the sender's address corresponding to the selection information received in step 2340 from the local memory set on the RAM 130 and attempts to set a call to the sender's address in step 2b 350. do. That is, the CPU 110 attempts to set up a call to the sender through the network control packet processing unit 170 and the network matching unit 180 in response to the redialing request of the receiver. As described above, the CPU 110, which attempts to set up a call using the address of the counterpart stored in the local memory, performs communication control with the subscriber in step 360 so that the subscriber 160 can communicate with the counterpart.

If it is determined in step 320 of FIG. 2B that the counterpart stored in the local memory does not have an address, the CPU processes the redialing requested by the subscriber 160 in step 370. The CPU 110, which has redialed the error as described above, performs a conventional outgoing communication process and receives the subscriber address of the other party's network dialed by the subscriber 160 to perform outgoing processing.

Therefore, when the incoming call according to the present invention stores the address of the other party transmitted in the packet from the UNI of the other party in the local memory, when the subscriber wishes to communicate with the subscriber of the called party of the other party stored in the local memory Redialing the address makes it easy to communicate with the other party with a complicated addressing system.

As described above, the present invention executes redialing using the address of the other party, which is transmitted from the other party to the packet when the call is received, thereby dialing the address of the other party having a complicated address system such as multimedia communication and high-speed information communication service. There is an advantage that you do not have to. In addition, by automatically dialing the address of the other party, the problem of input error of the other party's address can be automatically solved, thereby increasing the efficiency of using the system.
