The present invention relates to a method for guiding a number change of a wireless terminal, and more particularly, to a method for guiding a changed phone number in a text message to a calling terminal when the number of a called terminal is changed.

Recently, wireless terminals (for example, mobile phones, PDAs, etc.) have been widely used due to the development of information and communication technology.

This wireless terminal provides various services to terminal users.

Among them, the number change guide service is a service for guiding the changed phone number to the ARS and directly connecting to the changed number when the telephone number of the called terminal is changed, and when the telephone number is changed due to personal circumstances of the terminal user. You can inform them of their changed number for a certain period of time.

In this way, the caller can be informed of the changed phone number through the ARS can minimize the inconvenience caused by the phone number change.

However, this conventional number change guide method has the following problems.

In other words, when the incoming call to a predetermined terminal and the changed phone number are guided only to the ARS, a person with an ARS listener or an elderly person who does not have a good hearing function such as a hearing impairment cannot recognize the ARS contents accurately and recognize the changed phone number. There is a problem that is difficult to do.

In addition, even if the hearing function is good, there is a problem that it is very inconvenient because the ARS must be connected again when the memo sheet for describing the changed telephone number is not prepared.

Therefore, in order to solve the above-mentioned problem, the present invention guides the changed phone number not only to ARS but also to a text message when the number of the terminal is changed, so that the hearing function is not good or a note for describing the phone number is provided. It is an object of the present invention to provide a method for guiding a change of a number of a wireless terminal so that a changed telephone number can be easily recognized even if not prepared.

In order to achieve the above object, the present invention serves as a switch for a wireless terminal including at least a voice output unit capable of making / receiving text messages and listening to ARS, and a plurality of wireless terminals including the wireless terminal. A mobile telephone switching station for performing a call and the subscriber information of a predetermined terminal transmitted from the wireless terminal through the mobile telephone switching station, and a number change guide text message when the predetermined terminal is forwarded as a result of confirming the subscriber information. And a SMS center for transmitting a number change guide SMS to the wireless terminal through the mobile switching center in accordance with a transmission instruction of the number change guide text message of the home location register. Number of wireless terminal used for change number guidance system As a light guide, the method comprising: calling a predetermined terminal using (ⅰ) the radio terminal; (Ii) If the subscriber information of the predetermined terminal is inquired by the home location register and it is confirmed that the subscriber information is forwarded to the changed number as a result of confirming the subscriber information of the predetermined terminal, the home location register displays a number change guide text message on the wireless terminal. Instructing the SMS center to send a message; And (iii) the SMS center transmitting the number change guide text message to the wireless terminal according to the instruction of the home location register.                         

As a result, when the number of the terminal is changed, the changed telephone number is guided by a text message, so that the changed telephone number is converted into a number change guide message even when the hearing function is not satisfactory or when a memo for entering the telephone number is not prepared. It can be easily recognized.

Further, if the subscriber information of the predetermined terminal is inquired by the home location register and the subscriber information of the predetermined terminal confirms that the call is forwarded to the changed number, the terminal is connected to the number change ARS through the relay switch to connect the predetermined terminal. The method may further include listening to the number change announcement message according to the number change.

The number change guide text message may include a phone number before the change of the predetermined terminal and a phone number after the change.

Thereby, by guiding the changed telephone number and the telephone number before the change, the telephone number after the change can be known by referring to the telephone number before the change.

Further, the telephone number after the change can be registered in the telephone book of the wireless terminal.

This makes it possible to easily use the changed telephone number registered in the telephone book in the subsequent attempt of incoming call to the changed telephone number.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a number change guide system of a wireless terminal according to the present invention. 2 is a flowchart illustrating a number change guide method of a wireless terminal according to the present invention. 3 is a diagram illustrating an example of a number change guide text message. In addition, the present invention will be described mainly with the part that delivers the text message for the changed phone number to the terminal when the incoming call when the phone number is changed when the incoming call to the predetermined terminal, the ARS listening portion according to the number change guide ARS is conventional Explain instead of technology.

As shown in Fig. 1, the number change guide system for a wireless terminal according to the present invention includes a wireless terminal 10, a mobile telephone switching center 20, a home location register 30, an SMS center 40, a relay switch ( 50), and a number change ARS (60).

The wireless terminal 10 is a general wireless terminal, and may be at least a wireless terminal including a voice output unit (speaker) capable of sending / receiving text messages and listening to ARS.

A Mobile Switching Center (MSC) 20 is a switch that provides circuit switching services to mobile subscribers and serves as a switch for a number of wireless terminals, including the wireless terminal 10.

The Home Location Register (HLR) 30 inquires subscriber information of a predetermined terminal (not shown) sent from the wireless terminal 10 through the mobile switching center 20, and confirms the subscriber information as a result. When the terminal is forwarded, it instructs the SMS center 40 to transmit the number change guide text message to the wireless terminal.

The SMS center 40 transmits the number change guide SMS to the wireless terminal 10 through the mobile switching center 20 according to the transmission instruction of the number change guide text message in the home location register 30.                     

In the relay switch 50 and the number change ARS 60, when it is confirmed by the home position register 30 that the predetermined terminal is forwarded, the relay switch 50 is connected to the number change ARS 60 through the relay switch 50. Therefore, the number change guide according to the number change of the predetermined terminal can also be listened to.

Next, a method for guiding a number change of a wireless terminal according to the present invention will be described with reference to FIG. 2 is a flowchart illustrating a number change guide method of a wireless terminal according to the present invention.

As shown in Fig. 2, when the wireless terminal 10 is used to make a call to a predetermined terminal (for example, terminal number 011-123-1234) in step S1, the mobile telephone exchange station 20 passes through the home. The location register 30 queries the subscriber information for the given terminal.

If it is confirmed that the subscriber information for the predetermined terminal is forwarded to another number, for example, 1507-011-567-5678 (prefix 1507 is routed to the number change ARS) (i.e., in step S2), " Y " "," The home location register 30 instructs the SMS center 40 to transmit the number change guide text message to the wireless terminal 10 (S3).

Of course, if it is confirmed that the subscriber information for the predetermined terminal is forwarded to another number, it is routed to the number change ARS 60 through the relay switch 50 as in the prior art to listen to the ARS together. In addition, after listening to the ARS, the call may be directly connected to the changed number of the predetermined terminal.                     

Next, in step S4, the SMS center 40 transmits the number change guide text message to the wireless terminal 10 according to the number change guide text message transmission instruction from the home location register 30.

Here, the number change guide text message may include at least the telephone number before the telephone number change of the predetermined terminal and the changed telephone number, as shown in FIG. 3.

Finally, in step S5, the changed telephone number is modified and registered in the telephone directory of the wireless terminal 10, and then the telephone number can be directly dialed.

Here, the registration of the changed telephone number to the wireless terminal 10 may be registered by the terminal user directly to the changed number, preferably, the wireless terminal 10 has an automatic change registration function, so that the predetermined terminal If the phone number for the number is changed and receives a text message with the changed number may be registered in the number already stored in the wireless terminal automatically changed to the changed number.

As described above, according to the present invention, when the number of the terminal is changed, the changed phone number can be guided together with the text message as well as the ARS, so that the ARS listener can be compared with the elderly as compared to the conventional method where the changed phone number is only guided to the ARS. Even if the hearing function is abnormal or there is no hearing function, the ARS does not need to be accessed again even if a memo for writing the changed telephone number is not prepared.

While the invention has been particularly shown and described with reference to specific embodiments, it will be understood by those skilled in the art that the invention is not limited thereto and various modifications are possible.
