Hereinafter, with reference to the accompanying Figures 2 and 7 will be described in detail a preferred embodiment of the present invention.

2A and 2B are views for explaining a speed dialing method according to an embodiment of the present invention.

2A and 2B illustrate an example of performing the speed dialing of the present invention using a wired telephone and a wired telephone network. In other words, it is used to contact the electronics company's after-sales service center to receive inquiries, trouble reports, and after-sales service for home appliances. Thus, the calling terminal 21 is a telephone at home and the receiving terminal 22 is a telephone connected with a counselor at an after-service center.

Referring to FIG. 2A, the transmitting terminal 21 and the receiving terminal 22 are connected through a wired communication network 23. The originating terminal 21 is connected to the originating exchange 24, and the receiving terminal 22 is connected to the receiving exchange 27. The originating exchange 24 is connected to the speed dial server 25 so as to be able to input and output mutually, and the speed dial server 25 is connected to read data from the subscriber DB 26.

In Fig. 2A, the calling terminal 21 inputs a speed dial to the calling telephone number. For example, when a user wants to call A's customer service center, the user inputs the recognized speed dial number 100.

As in the case of companies such as 002 Dacom and 008 Onse Telecom, which have long distance service, they can raise awareness of users by attaching them back and forth to each other. If you always stick around with your company's publicity or signage, you can recognize them without memorizing them separately. In other words, 2424 can be used as a shortcut number for moving companies and 0404 can be used for construction companies to promote the company's work. In addition, a number that can be displayed in Korean, such as 1004 (angel), can also be used as a shortcut number.

If the user inputs a desired speed dial number, the calling switch 24 determines whether it is a general calling number or a calling number by speed dialing. In the case of the general calling number, the call connection is performed to the receiving switch 27 of the corresponding receiving terminal 22 side. On the other hand, if it is determined that the calling number is by speed dialing, the speed dial number is transmitted to the speed dial server 25. The speed dial server 25 receives the speed dial number and searches the subscriber DB 26 to read the actual phone number. When the speed dial server 25 reads the telephone number, the speed dial server 25 transmits the call number to the originating exchange 24 and attempts to connect the call to the receiving exchange 27. Therefore, the calling terminal 21 can make a telephone call with the desired receiving terminal 22 by inputting a speed dial.

2A illustrates an example in which a speed dial server and a subscriber DB are linked to an originating exchange. However, it is also possible to implement the speed dial server and the subscriber DB to interoperate with the home exchange for reasons of load balancing, which is disclosed in FIG. 2B.

2B, the wired communication network 23 is provided with a home exchanger 28 separately from the originating exchange 24 and the receiving exchange 27, and the speed dial server 25 and the subscriber DB 26 have a home exchange ( 28) is linked to work. The originating exchange 24 transmits the incoming call number to the home exchange 28, and the home exchange 28 transmits the speed dial number to the speed dial server 25 when it determines that the calling number is the dialing number by speed dialing. The speed dial server 25 receives the speed dial number and searches the subscriber DB 26 to read the actual phone number. When the speed dial server 25 reads the telephone number, the speed dial server 25 transmits the telephone number to the home exchanger 28 and the home exchanger 28 transmits the telephone number to the calling exchange 24. The originating exchange 24 attempts a call connection to the receiving exchange 27 using the telephone number inputted to make a call between the originating terminal 21 and the receiving terminal 22.

In the above-described embodiment, the subscriber DB is linked to the speed dial server 25. However, in the case of FIG. 2A, when a company providing subscriber information is connected to a wired communication network, the speed dial server accesses the DB of the corresponding company and provides a phone number. It is also possible to search. In the case of FIG. 2B, the subscriber DB is interlocked with the home switch 28 so that the speed dial server 25 may search the subscriber DB through the home switch 28.

The subscriber DB 26 of FIGS. 2A and 2B registers and stores a shortcut number and a telephone number in advance from various subscribers.

3 is a table for explaining stored data of the subscriber DB of FIGS. 2A and 2B.

Referring to Figure 3, the shortcut number, the subscriber and the phone number are stored in one-to-one correspondence. That is, it can be seen that the speed dial number 100 is A company, the phone number is 123-4567, the speed dial number 200 is B company, and the phone number is 234-5678. Finally, 300 is C, and the phone number is 345-6789. Therefore, when the user enters the speed dial number 100, the speed dial server 25 searches the data table of the subscriber DB 26 to confirm that the A number is 123-4567, and transmits it to the calling exchange 24. do. Then, the originating exchange 24 transmits the actual originating telephone number to the receiving exchange 27 to perform the call connection.

The above-mentioned speed dialing method will be described in more detail with reference to the flowchart of FIG. 4.

4 is a flowchart illustrating a speed dialing method according to an embodiment of the present invention.

Referring to FIG. 4, the user inputs a speed dial through the calling terminal 21 (step 401). In this case, the speed dial includes a specific dual tone multi frequency (DTMF) key along with the speed dial number. Here, the specific DTMF key is a speed dial identifier. That is, the calling terminal 21 inputs 100 # as a speed dial. Where 100 is a shortcut number and # is a DTMF key. The calling terminal 21 transmits an input speed dial to the calling switch 24. The originating exchange 24 recognizes the DTMF key included in the speed dial (step 403). That is, the calling switch 24 recognizes that the calling call number input is a number for speed dialing, not a telephone number. Then, the speed dial number included in the input speed dial is transmitted to the speed dial server 25 (step 405). The speed dial server 25 receives the speed dial number, searches the subscriber DB 26, and reads out the telephone number (step 407). Referring to FIG. 3 described above, it can be seen that the speed dial number 100 is A's telephone number 123-4567. The speed dial server 25 transmits the telephone number to the calling exchange 24 for connection (step 409). The originating exchange 24 requests a call connection to the receiving exchange 27 using the telephone number input from the speed dial server 25 as the calling number (step 411).

Therefore, the user of the calling terminal 21 can be connected to the desired receiving terminal 22 through a convenient speed dial without having to press the phone number one by one.

5 is a view for explaining a single-axis dialing method according to another embodiment of the present invention.

5 illustrates an example of performing the speed dialing of the present invention using a mobile telephone and a mobile communication network. In other words, if you are traveling by car, use it to contact the mobile service center to receive business services for sudden breakdowns. Thus, the calling terminal 21 is a mobile phone and the receiving terminal 22 is a mobile phone connected to a mobile service center.

Referring to FIG. 5, the calling terminal 51 is connected to the calling base station 52 to form a call path, and the calling base station 52 is controlled by a base station controller (not shown). Then, the originating base station 52 is connected to the originating MSC 53 for controlling the call of the originating terminal 51, the originating MSC 53 is a speed dial server 54 for reading a shortcut number for speed dialing Connected with Speed dial server 54 is connected to subscriber DB 55 for retrieving a telephone number using a speed dial number. The originating MSC 53 is connected to the receiving side for performing a call connection via the mobile communication network 56. The receiving side includes a receiver station 58 for forming a call path between the receiving terminal 59 and the receiving terminal 59, and a receiving MSC 57 for controlling a call of the receiving terminal 59.

In Fig. 5, the calling terminal 51 inputs a speed dial to the calling telephone number. Here, the speed dial includes the speed dial number and the specific DTMF key as described in FIG. The originating terminal 51 transmits a terminal alliance message to the originating MSC 53 through the originating base station 52 for the call connection with the mobile communication network 56. Here, the terminal association message includes a terminal's unique mobile subscriber identity number information, user data and signal data encryption, etc., which allow the MSC to check the service eligibility of the terminal. The originating MSC 53 examines the eligibility of the service of the calling terminal 51 in response to the terminal association message, and if determined to be eligible, proceeds to the outgoing call processing process and sends a terminal cooperation permission message for the service request to the calling terminal ( 51). The originating terminal 51 transmits a call establishment message to the originating MSC 53 when the terminal cooperation permission message is received. The call setup message is a message for the caller 51 requesting call setup with an arbitrary receiver 59, and includes a telephone number of the caller 51 and the called terminal 59, information for channel formation, and the like. . Here, the originating MSC 53 determines whether the calling number included in the call setup message is a general calling number or a calling number by speed dialing. In the case of the general calling number, the calling terminal 51 is connected to the receiving terminal 59 through a subsequent call setup process.

On the other hand, if it is determined that the calling number is by speed dialing, the speed dial number is transmitted to the speed dial server 54. Here, the originating MSC 53 recognizes the originating number by speed dialing by a specific DTMF key included in the speed dial. The speed dial server 54 receives the speed dial number and searches the subscriber DB 55 to read the actual phone number. The speed dial server 54 transmits the telephone number to the calling MSC 53 when the telephone number is read. In this way, the originating MSC 53 stores the telephone number input from the speed dial server 54. The originating MSC 53 performs call processing in response to this call setup message and the originating base station 52 notifies the originating MSC 52 that the radio resource allocation has been completed. When the radio resource allocation is completed, the originating MSC 53 translates the telephone number of the receiving terminal 59, which is stored in advance, and transmits a call setup message to the receiving MSC 57. When the radio link is established between the receiving base station 58 and the receiving terminal 59, the receiving terminal 59 and the calling terminal 51 are connected to each other to make a call.

That is, the mobile service center may receive a quick service since the mobile service center may be connected to the mobile service center by using a mobile phone using a shortcut number, for example, 8282 (quickly) in an emergency car breakdown situation.

Although the above-described embodiments have been described as inputting a speed dial by a user's operation, it is also possible to implement a case in which a voice is recognized and converted into a key input signal.

A case in which the calling terminal of FIG. 5 has a function of recognizing voice will be described in detail with reference to FIG. 6.

In FIG. 6, the control unit 511 transmits the input signal to the key signal receiver 514 when a key signal is input by the keypad, and transmits the signal to the voice recognition unit 512 when a voice signal is input. For example, if a user wants to make a call to a mobile service center, the user inputs the arm arm 8282 by voice. The speech recognizer 512 recognizes the speech signal and transmits the speech signal to the converter 513. The converter 513 converts the voice signal into a key signal and transmits the voice signal to the key signal receiver 514. Here, the converted key signal is recognized as the same signal as the key signal by the key input. Accordingly, the key signal receiver 514 transmits the input key signal to the transmission data generator 515. The transmission data generation unit 515 generates and transmits transmission data including the speed dial identifier under the control of the control unit 511.

This transmission data is shown in FIG.
