BRIEF DESCRIPTION OF THE DRAWINGS FIG.
An embodiment of the present invention will be described in detail.

FIG. 1 shows a communication network according to an embodiment of the present invention. In the case of this embodiment, the analog public network PSTN is applied.

The analog public network PSTN accommodates a large number of telephones TL1, TL2,..., Which are analog communication terminals, and performs line control of communication between the telephones TL1, TL2,. , .. is provided with a function to control the history of telephone numbers.

Here, the telephone number registered in each telephone is set to the user when the user of each telephone concludes a usage contract with a line provider of the analog public network PSTN. However, in the present invention, for the sake of simplicity, a description will be given of a telephone assuming that a telephone number is registered.

The analog public network PSTN stores a telephone number history table including a set of an old telephone number and a new telephone number as shown in FIG. Telephone TL1, TL
.. Are created and saved, and the contents of the telephone number history table are referred to as necessary.

FIG. 3 shows a telephone TL (TL1, TL2,.
An example of the configuration of ()) is shown.

In FIG. 1, a control unit 1 controls the operation of the telephone. The operation unit 2 is used by a user to operate the telephone, and a numeric keypad for dial operation and various functions (not shown) of the telephone.
Consists of various keys for realizing. The display unit 3 is for the telephone to display and output various kinds of information (for example, a telephone number operated and input and a state of the apparatus) to the user.

The microphone 4 is for inputting voice information for a call, and the speaker 5 is for outputting voice information for a call.
Is for performing voice input from the microphone 4 and voice output from the speaker 5 for a call.

The data modem 7 has an analog public network PST
N for exchanging information of a telephone number notification service similar to the calling telephone number notification service. The network control device 8 transmits the telephone to the analog public network PS.
This is for connecting to the TN and performing a predetermined outgoing / incoming call operation. Further, the network control device 8 has a function of transmitting and receiving a push button signal.

This telephone has a telephone directory function, and FIG. 4A shows an example of telephone directory table information for realizing the telephone directory function. The telephone directory table information includes a large number of registered telephone number information, and each registered telephone number information includes a one-touch dial number or abbreviated dial number, a telephone number, and a name, as shown in FIG. .

Here, in the name, appropriate information such as the name of the destination user is registered. The contents of each registered telephone number information are input and registered by the user operating the operation unit 2 of the telephone as appropriate.

The one-touch dial numbers are the respective dial numbers of the one-touch dial function of the telephone, and the abbreviated dial numbers are the respective dial numbers of the abbreviated dial function of the telephone.

With the above configuration, when the telephone number of the terminal TL is changed, the telephone TL notifies the exchange of the analog public network PSTN of the change of the telephone number in the procedure shown in FIG.

First, the calling terminal (telephone TL) sends a call signal (DC loop closed) to the exchange, and when the exchange accepts the call from the calling terminal, the calling terminal issues a tone (D) to the calling terminal.
T).

Thus, the calling terminal sends telephone number change notification information to the exchange by a push button signal (PB signal). The telephone number change notification information includes the telephone number before the change and the telephone number after the change. For example, a signal format such as “## 001 # (old telephone number) # (new telephone number)” Sent out. Here, “## 001” is a signal representing a telephone number notification.

After transmitting the telephone number notification information to the exchange, the calling terminal transmits a disconnection signal (DC loop disconnection) to the exchange. As a result, the exchange disconnects the line with the calling terminal. At this time, since the telephone number notification information has been received, the analog public network PSTN (exchange) creates and stores the telephone number history table as described above based on the notified telephone number change notification.

FIG. 6 shows an example of a procedure for exchanging with the exchange (analog public network PSTN) when the telephone TL makes a call.

First, the calling terminal (telephone TL) sends a calling signal (closed DC loop) to the exchange, and when the exchange accepts the call from the calling terminal, the calling terminal issues a tone (D) to the calling terminal.
T).

Thus, the calling terminal sends a selection signal representing the telephone number of the called telephone to the exchange using the push button signal (PB signal). Upon receiving the selection signal, the exchange analyzes the content and refers to the telephone number history table to check whether or not there is an element in which the telephone number corresponding to the selection signal is registered in the old telephone number.

If the old telephone number is registered, the corresponding new telephone number is obtained by referring to the telephone number history table in which the received old telephone number is registered.
In order to notify the calling terminal of the new phone number after the change,
By the push button signal (PB signal), the same telephone number change notification information as described above is transmitted.

Thereafter, the exchange applies the acquired new telephone number, performs a calling operation to the called side, and starts a ringing operation, and transmits a ringing tone (RBT) to the calling terminal. When the receiving side answers the incoming call, the transmission of the ringing tone is stopped and a response signal is transmitted to the calling terminal.

Thus, thereafter, a call operation is performed between the calling terminal and the called terminal.

Also, at this time, since the telephone number change notification information is received from the exchange, the calling terminal checks whether the notified old telephone number is registered in the telephone directory table information. Updates the contents of the telephone number to the value of the notified new telephone number.

As described above, in this embodiment, when a call is made and the telephone number of the destination has been changed, the telephone number change notification information is received from the analog public network PSTN. Can be updated to a new telephone number, so that a call can be made from the next call by applying the new telephone number.

If the telephone number has been changed, the PSTN side of the analog public network applies the changed telephone number and makes a call to the called side. Communication can be performed more smoothly.

FIG. 7 shows an example of a procedure for exchanging with the exchange (analog public network PSTN) when the telephone TL receives a call. In this case, the calling telephone number notification service is basically applied, and the calling telephone number is notified.

That is, the exchange of the analog public network PSTN first inverts the polarities of the lines L1 and L2, and then transmits a predetermined ID receiving terminal activation signal. Thereby, the receiving terminal (telephone TL) forms a DC loop as a primary response signal.

In this way, when the receiving terminal makes a primary response, the exchange sends a calling ID (caller telephone number) and the like in the form of a modem signal (for example, a V.23 modem signal) in a predetermined signal format (described later). When the receiving terminal receives the modem signal, it cuts off the DC loop as a reception completion signal.

When the receiving terminal completes receiving the calling ID and the like in this way, the exchange sends a predetermined calling signal, and the receiving terminal forms a DC loop as a secondary response signal in response to the calling signal. Accordingly, the exchange depolarizes the lines L1 and L2, and thereafter, a normal telephone call (communication) operation is performed.

FIG. 8 shows an example of a signal format of a modem signal when transmitting a calling ID or the like in such a calling sequence.

This signal format includes a control signal SOH indicating the start of the heading of the information message, a header for transmitting information from the exchange to the destination terminal, the start of the text, and the end of the heading, as shown in FIG. , A control signal STX indicating the end of the information, a control signal STX indicating the end of the information,
The error detection code CHK is sequentially arranged. In addition,
Immediately before each control signal, a predetermined transmission mode control signal DLE is added.

As shown in FIG. 3B, "information" is a service type for notifying that the content of the transmission information is a caller notification service, and a subsequent parameter (1).
Parameter indicating the total number of bytes from (1) to (n) and the parameter (1) forming the content of the transmission information
~ (Parameter (n)).

As shown in FIG. 3C, each parameter is composed of parameter type information indicating the type of the parameter, information content length information indicating the number of bytes of the information content, and information to be transmitted (in this case, , Caller number).

Each control signal is composed of data having a length of 7 bits per word.

In this embodiment, "old telephone number" and "new telephone number" are applied as parameters.
The "new telephone number" is the same as the notification telephone number in the normal outgoing telephone number notification service, and the "old telephone number"
Is added when the telephone number of the calling terminal has been changed as described above, and the contents thereof are the old telephone numbers registered in the telephone number history table corresponding to the calling terminal.

On the other hand, at the called terminal, when the telephone number notification information received from the exchange at the time of the incoming call includes the "old telephone number" and the "new telephone number", the received old telephone number is stored in the telephone directory table information. Find out if you are registered with
If registered, the contents of the telephone number are updated to the value of the notified new telephone number.

As described above, in this embodiment, when a call is received,
When the telephone number of the calling terminal has been changed, the outgoing telephone number information received from the analog public network PSTN includes the "old telephone number" and the "new telephone number". The contents of the telephone directory table information can be updated to a new telephone number. As a result, the calling operation can be performed by applying the new telephone number from the time of the next call of the called terminal, and a wrong call can be avoided.

FIG. 9 shows an example of processing of the telephone TL when the telephone number is changed.
