Method and System for Providing Announcement in Case of Telephone Number's Registration Error in Received Call's Switchover}

The present invention relates to a method and system for providing announcements when a registration error of a forwarding telephone number is provided. More specifically, if a user who subscribes to the incoming phone number change service registers or changes the incoming phone number and an incorrect phone number is entered, the exchange recognizes an error in entering the phone number and informs that the phone number has been entered incorrectly. The present invention relates to a method and a system for providing an announcement when a call forwarding registration number is automatically provided to a user.

As is well known, with the recent rapid development of electronics and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also Internet access, video communication and video message transmission using mobile communication terminals. In addition, due to the rapid spread of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such as a considerable amount of contact generated through human communication.

Therefore, when the mobile communication terminal is lost or accidentally left in a specific place, for example, a home or an office, many problems occur. In other words, if the mobile communication terminal is lost or accidentally held for a long time, it is needless to say that the person does not want to contact with another person, and there is little way for the other person to contact him. Therefore, a user who does not have a mobile communication terminal may not receive important contacts and may have great difficulty.

In addition, when other people call the person who does not have the mobile terminal and the call is not connected, the user who makes the call keeps trying to connect the call until the announcement is received from the phone. There is a problem to increase. In addition, when the call is not connected, the user who makes the call tends to increase the communication traffic even more due to the habit of calling the call again later.

In order to solve these problems, the incoming telephone number change service has been newly introduced. Incoming phone number change service is a phone that cannot register with a landline phone or mobile phone that can make a call if the user who has subscribed to the incoming phone number change service fails to possess the mobile terminal for the same reason as described above. When Call attempt is made by number, it is a service that allows call attempt to be registered to new registered phone number.

1 is a configuration diagram schematically showing the principle of the incoming telephone number change.

The terminal B 120 is a terminal registered in the incoming telephone number change service, and is a terminal which the user cannot hold for some reason. The user who has no possession of the terminal B (120) is the terminal C 130 or any other communication terminal to the telephone number of the terminal C (130) via the network communication network 140 to the destination telephone number for the terminal B (120) Register with Accordingly, when a call attempt is generated from the terminal A 110 to the terminal B 120, the network communication network 140 attempts to call the terminal C 130 without making a call attempt to the terminal B 120.

Here, the network communication network 140 is a concept including a mobile communication network and a public switched telephone network including a wireless base station and a telephone switching center.

On the other hand, the incoming telephone number change service is generally provided in two ways. One is a conditional incoming telephone number change service. When a call attempt from terminal A 110 to terminal B 120 occurs, a call from terminal B 120 rings for a certain period of time, and then a response from terminal B 120 is answered. If not, the call is attempted by the terminal C (130) registered as the incoming phone number. Of course, this case will be possible when the power of the terminal B (120) is on. The other is an unconditional incoming phone number change service. When a call attempt from the terminal A 110 to the terminal B 120 occurs, a call attempt is made to the terminal C 130 registered as the called phone number. Of course, an unconditional incoming phone number change service is mainly used due to the nature of the incoming phone number change service.

However, when using the incoming telephone number change service, the user manually enters a new incoming telephone number by using an arbitrary terminal, which is caused by a mechanical error of the terminal itself such as a mistake of a user or a specific key button of the terminal. This often causes a new incoming telephone number to be entered incorrectly. In this case, even if an incorrect destination telephone number is entered, the destination number is registered without any verification or warning. Here, the wrong incoming telephone number refers to a telephone number that does not conform to the telephone number system used in each country. For example, if a station number other than the number registered as a station number (02, 031, 041, 052, etc.) is entered in the system of telephone numbers used in Korea, or the number of digits of the telephone number does not reach or exceed the preset number to be.

Therefore, when another person attempts to call a terminal with an incorrect incoming phone number, he / she will hear the announcement of the station number, etc., and try again because the call is not connected or recognize it as a system error of the service provider. Side effects such as damage to the image will occur. On the other hand, a user who registers a forwarding phone number recognizes that the call forwarding function is set to a normal phone number, and realizes that there is a problem in registering the forwarding phone number after not receiving an important call. There is a situation.

In order to solve the above-mentioned problems, the present invention, if a user subscribed to the incoming telephone number change service registers or changes the incoming telephone number, if an incorrect telephone number is input, the telephone exchange office recognizes an error in inputting the telephone number. Provides a method and system for providing announcements when a call forwarding phone number registration error is automatically provided to a user informing them of an incorrect entry.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is a block diagram schematically illustrating an incoming phone number change service system according to an embodiment of the present invention.

Incoming telephone number change service system according to the present invention is a terminal (200, 202), wireless base station 210, telephone exchange office 220, home location register (HLR: 230), visitor location register (VLR: Visitor Location Register (240) and public switched telephone network (250).

The terminals 200 and 202 include a mobile communication terminal 200 or a wired telephone 202 as terminals 200 and 202 for using an incoming telephone number change service. When the incoming telephone number change service is used using the mobile communication terminal 200, the mobile telephone terminal 200 is connected to the telephone exchange office 220 through the wireless base station 210, and when the landline telephone 202 is used, the public telephone switching network 250 is used. It is connected to the telephone exchange 220.

The wireless base station 210 is wirelessly connected to the mobile communication terminal 200, and transmits a call attempt to change the incoming telephone number generated in the mobile communication terminal 200 to the telephone exchange 220 through a wired network It has a base station.

The telephone exchange office 220 has a control function and a linkage function with the public switched telephone network 250 so that a plurality of wireless base stations 210 can be efficiently operated. In addition, the telephone exchange station 220 has a station number table in which approximately 1,200 to 1,800 kinds of station numbers are stored. Therefore, when a call attempt is generated from the terminal 200 or 202 to an arbitrary telephone number, the telephone exchange station 220 determines whether the telephone number transmitted from the terminal 200 or 202 is a telephone number conforming to the station number system using the station number table. Primary judgment function. An internal configuration of the telephone switching center 220 according to the present invention will be described in more detail with reference to FIG. 3.

The home location register 230 is a kind of database used in the telephone exchange office 220 and stores an original database including terminal information and subscribed service information for all registered subscribers. Accordingly, the information of the subscriber who has changed the incoming telephone number is stored in the home location register 230 so that the service information of the subscriber is updated. In addition, the subscriber's information is provided to each component installed in the telephone communication network in real time to provide mobility to the mobile communication terminal 200.

The visitor location register 240 functions to temporarily keep a copy of the original subscriber's original database when a subscriber registered at a particular telephone exchange office 220 moves to an area managed by another telephone exchange office 220. That is, the visitor location register 240 in the area where the subscriber has moved receives and stores the subscriber's information from the home location register 230 of the telephone exchange office 220 where the subscriber is registered.

Thus, each time a subscriber attempts a call, the subscriber is sent to the visitor location register 240 in the moved area without requesting the subscriber information from the home location register 230 of the registered telephone exchange office 220. Provides the ability to process call attempts directly using information. Although the visitor location register 240 having such a function is illustrated in FIG. 2 as being installed outside the telephone exchange office 220, the visitor location register 240 may be installed inside the telephone exchange office 220.

In the present invention, when the user uses the incoming telephone number change service in a region other than the region where he is registered, the incoming telephone number changing service can be used directly by using the user information stored in the visitor location register 240 of the moved region. do.

The public switched telephone network 250 functions to connect a call attempt to the telephone exchange office 220 when the user uses the incoming telephone number change service by using the wired telephone 202.

3 is a block diagram schematically showing the internal configuration of the telephone exchange 220 according to the embodiment of the present invention.

The internal configuration of the telephone exchange station 220 according to the embodiment of the present invention includes a central control unit 300, a signal transmitting and receiving unit 310, a station number table (Table) unit 320 and the announcement unit 330.

Referring to FIG. 1 together, the central control unit 300 receives a signal from the wireless base station 210 or the public switched telephone network 250 when a call attempt is made from the terminals 200 and 202, thereby validating a registered subscriber. It determines whether the call is attempted, whether the telephone number is properly input, and where the destination of the received signal is.

The signal transmitting and receiving unit 310 performs a function of transmitting and receiving signals with the wireless base station 210 or the public switched telephone network 250, and the signals transmitted and received may be both a voice signal and a data signal.

The station number table 320 stores a system of station numbers used in each country. The country number system of our country will be described using Table 1 as an example.

Station number Minimum value of digits Maximum value of digits 001 9 16 007001 16 16 022201 10 10 02446 9 9 ... ... ...

Table 1 lists the minimum and maximum values for the station number and the number of digits beginning with the station number. That is, if the first three digits of the telephone number input from the terminals 200 and 202 are '001', the number of the corresponding telephone number is at least 9 to 16 digits, and if the number is 007001, the digit of the corresponding charge number. Means only 16 digits are allowed. Therefore, if the telephone number inputted from the terminals 200 and 202 has a station number starting with '001' and the number of digits of the telephone number is less than 9 or greater than 16, it indicates that the telephone number is not correctly input. For example, in Seoul, since the phone number is fixed to 02-xxx (x) -xxxx, the minimum and maximum values of the number of the telephone number are equal to 9 or 10.

Accordingly, the central control unit 300 compares the call forwarding telephone number transmitted from the terminals 200 and 202 through the wireless base station 210 or the public switched telephone network 250 with the station number data registered in the station number table unit 320. To determine whether it is a normal telephone number.

The guidement providing unit 330 provides a guidement for informing a user of an error in inputting a telephone number to the corresponding terminal 200 or 202 when a call forwarding telephone number is incorrectly input. That is, the telephone exchange station 220 receives the call forwarding phone number, and compares the received call forwarding phone number with the station number table unit 320 and determines that it is an incorrect phone number. The terminal 200 and 202 which transmits the number provide a notice indicating that the telephone number is incorrectly input. For example, the message "The forwarding number you have registered is the wrong phone number. Please check and register again." The subscriber who tried to forward the call recognizes that he or she has incorrectly entered the forwarding phone number. You can re-register immediately.

4 is a flowchart illustrating a process of registering a call forwarding telephone number according to an embodiment of the present invention.

A user who wants to use the call forwarding service accesses a telephone exchange station 220 that provides an incoming phone number change service by using any terminal 200 or 202 (S400). If the user's terminal 200 or 202 tries to dial out of the registered area of the registered telephone exchange office 220 from another area, the telephone exchange station 220 managing the area where the user is located is originally registered by the user. A call attempt is immediately approved using the stored user information transmitted from the local telephone exchange 220 to the visitor location register 240.

Here, the method of accessing the telephone exchange office 220 is a special function key such as * 71, for example, when using the mobile communication terminal 200 of the same operator as the mobile communication terminal 200 subscribed to the incoming telephone number change service. Enter the number associated with the incoming call number change service is possible. For example, when the mobile number of the mobile communication terminal 200 subscribed to the incoming phone number changing service is '011', the incoming phone number changing service is performed using the mobile communication terminal 200 having the carrier number of '011'. This is the case.

On the other hand, when using a mobile communication terminal 200 or a landline telephone 202 having a business number different from that of the mobile communication terminal 200 subscribed to the incoming telephone number change service, for example, 011-200- If you enter a phone number, such as 8282, you can use the incoming phone number change service.

When connected to the incoming phone number change service, the call forwarding target phone number is inputted to the terminals 200 and 202 according to the guidance message transmitted from the telephone exchange station 220 and transmitted to the telephone exchange station 220 (S402).

Here, the call forwarding target phone number refers to a phone number of a terminal subscribed to a call forwarding number change service to be forwarded. If the phone number entered by the user is not subscribed to the incoming phone number change service, an announcement is provided that the phone number is not registered, and the incoming phone number change service cannot be used.

When the call forwarding target phone number is authenticated, a password is input according to the announcement and transmitted to the telephone exchange station 220 (S404). Entering a password is a user authentication process that is passed to prevent another person from arbitrarily forwarding the user's terminal.

When the user authentication is performed in the password input step, the call forwarding phone number is input to the terminal according to the announcement and transmitted to the telephone exchange office 220 (S406).

Here, the call forwarding phone number refers to a phone number of a call destination target terminal that will instead perform a call attempt that occurs with the call forwarding target phone number.

The telephone exchange station 220 determines whether the call forwarding telephone number inputted and transmitted from the terminals 200 and 202 using the station number table 320 is suitable for the normal telephone number system (S408).

If it is determined in step S408 that the call forwarding target phone number is not a normal number, the telephone exchange office 220 inputs an incorrect phone number to the terminals 200 and 202 which input the call forwarding target phone number through the announcement message providing unit 330. It provides a guide that has been (S410).

Otherwise, if it is determined in step S408 that the call forward target phone number is a normal number, the telephone exchange station 220 transmits the received call forward target phone number and the call forward target phone number to the home location register 230 (S412).

The home location register 230 stores the received call forwarding phone number in the area of the call forwarding service information among the user information corresponding to the received call forwarding target phone number (S414). Therefore, all subsequent call attempts to the call forwarding target phone number are sent to the terminal having the call forwarding phone number.

Of course, if the incoming telephone number change service is used in the management area of the telephone exchange office 220 other than the region managed by the telephone exchange office 220 where the user's terminals 200 and 202 are registered, the region where the user is currently located. The information of the incoming phone number change service among the user information of the visitor location register 240 connected to the telephone exchange office 220 managing the service will be updated.

It will be appreciated by those skilled in the art that the present invention is not limited to the above embodiments, and that various modifications and changes can be made without departing from the spirit of the present invention.

As described above, when the call forwarding telephone number service according to the present invention is used, the announcement is provided immediately when the call forwarding telephone number is incorrectly inputted due to a user's mistake or a mechanical failure of the terminal. Recognize the call and re-register the call forwarding phone number.

Through this, if a call forwarding phone number is incorrectly input in the conventional forwarding phone number service, the subscriber who switched the call does not receive a phone call or provides a call announcement that occurs to a user who has performed a call attempt to the subscriber who switched the call. By eliminating continuous call attempts, we can eliminate the traffic on the telephone network.
