Method and System for Providing Short Message Service in Case of Incorrect Telephone Number's Registration in Received Call's Switchover}

The present invention relates to a method and system for providing a Short Message Service (SMS) when registering an incorrect forwarding telephone number. More specifically, if an incorrect phone number is registered as a new forwarding number of a user who has subscribed to the forwarding phone number change service, a message indicating that the forwarding number is incorrectly entered into the original change target terminal when a subsequent call occurs. The present invention relates to a method and a system for providing an SMS when registering an incorrect call forwarding phone number for automatically providing an SMS.

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, even if you have a mobile communication terminal, if you are participating in a special situation where you cannot make a call, for example, a meeting or a seminar, it may be difficult to turn off the mobile terminal or receive an incoming call. have.

Furthermore, if other people call to users who do not have or do not have a mobile communication terminal and the call is not connected, the caller continues to attempt to connect to the phone until they hear the announcement from the telephone. Since there is a problem to increase the communication traffic (Traffic). 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 a call attempt is made by a number, it is a service that allows a call attempt to be registered to a 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. A user who is unable to possess terminal B 120 transfers the telephone number of the terminal C 130 to the terminal C 130 or any other communication terminal through the network communication network 140 to the terminal B 120. Register by number. 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 is received from terminal B 120. If not, the call attempt is made to the terminal C 130 registered as a call forwarding 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 call forwarding 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.

The incoming telephone number change service is mainly used when the user does not possess the mobile communication terminal for some reason, but may be used even when the mobile terminal is specially possessed.

For example, when a user attends a place requiring quietness such as a meeting or a seminar, the user has a mobile communication terminal, but it becomes very difficult to make a phone call. In this case, the mobile communication terminal is usually turned off or the mobile communication terminal is set to the vibration mode.

In such a case, the call forwarding service can be set up as a call forwarding phone number of another person's terminal that can receive incoming calls for the user. There will be. Therefore, if only the correct call forwarding phone number is registered can be greatly helped to the user can be contacted on behalf of someone urgently.

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

Therefore, when another person attempts a call to a terminal that has an incorrect call forwarding phone number registered, he / she hears the announcement of the station number, etc. Side effects such as damage to the operator's image will occur.

On the other hand, a user who registers a call forwarding phone number often recognizes that the call forwarding function is set to a normal phone number and does not receive an important call, and later finds out that there is a problem in registering the call forwarding phone number. It is a situation that is causing even greater side effects.

In order to solve the above problems, the present invention, if a wrong telephone number is registered as a new incoming number of the user subscribed to the incoming telephone number change service, when the subsequent call occurs to inform that the incoming number was incorrectly entered to the original incoming change terminal Provided are a method and a system for providing an SMS when registering an incorrect call forwarding phone number that automatically provides an SMS of contents.

Therefore, when the incoming change is set in the incoming change terminal 200, the call attempt to the incoming change terminal 200 is connected to a destination target terminal having a newly registered incoming number.

The wireless base station 210 refers to a base station having a wireless transceiver that receives a call attempt from an arbitrary terminal (not shown) to the incoming change terminal 200 and transmits it to the telephone exchange 220. Here, any terminal includes not only a mobile communication terminal but also a general landline telephone. When a call attempt is made to the incoming change terminal 200 by a wired telephone, a signal is transmitted to the telephone exchange center 220 through a public switched telephone network (PSTN) (not shown).

The telephone exchange center 220 has a control function and an interworking function with the public switched telephone network to enable a plurality of wireless base station 210 to 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. The telephone exchange office 220 performs a function of determining whether the call forwarding telephone number stored in the home location register 230 to be described later is a number that conforms to the station number system using the station number table. 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. Therefore, the information of the subscriber who has changed the forwarding telephone number is stored in the home location register 230 so that the service information of the subscriber is updated. In addition, the subscriber information is provided to each component installed in the telephone communication network in real time to provide mobility to the mobile communication terminal 202.

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, the central control unit 300 receives a signal from a wireless base station 210 or a public switched telephone network when a call attempt is made from an arbitrary terminal, and receives a signal from a subscriber registered with the telephone switching center 220. It determines whether it is a valid call attempt, whether the call forwarding telephone number received from the home location register 230 is the correct number, and where the destination of the received signal is.

The signal transmitting and receiving unit 310 transmits and receives a signal to or from a wireless base station 210 or a public switched telephone network, and the signal 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 Korea will be explained 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 ... ... ...

In Table 1, the minimum and maximum values of the number of digits (Digit) preset in each station number are displayed. That is, if the first three digits of a telephone number input from any terminal is '001', the number of the corresponding telephone number is at least 9 to maximum 16 digits. It only means that it is possible. Therefore, if the station number of the call forwarding telephone number received from the home location register 230 starts with '001' and the number of digits of the telephone number is less than 9 or more than 16, it indicates that the telephone number is not properly input. For example, in Seoul, since the telephone number is fixed to 02-xxx (x) -xxxx, the minimum and maximum values of the number of the telephone number have the same value of 9 or 10.

That is, the central control unit 300 compares the call forwarding telephone number received from the home location register 230 with the station number data registered in the station number table 320 to determine whether or not it is a normal phone number.

The announcement message providing unit 330 is configured to perform a call attempt when an incorrect call forwarding telephone number is registered in the call change terminal 200 when a call attempt is generated from any terminal to the call change terminal 200. It provides guidance such that station number is due.
