DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic connection area switching system, and more particularly to a mobile communication system such as a cellular telephone system and a communication system using a subscriber ID card.

[0002]

2. Description of the Related Art Conventionally, this type of connection area switching method involves changing the additional code for identifying the connection area on the calling terminal side in response to a caller's recall instruction, and performing a re-transmission operation to connect the next candidate. The connection operation to the area is performed.

As such a connection area switching method, there is a telephone for a car telephone system disclosed in Japanese Patent Application Laid-Open No. 1-259636.

In this mobile telephone system telephone, the calling terminal side stores the telephone number of the connection destination including the connection area identification code first input by the caller, and the terminal to receive the call from the exchange to the connection area indicated by the identification code. When there is a notification that there is no such message, the calling terminal automatically replaces the next candidate connection area identification code with the next candidate according to the caller's call recall instruction, and retransmits the call.

[0005]

In the prior art, by performing a retransmission operation on the transmitting terminal side, the time from the start of the initial transmission operation to the completion of connection becomes longer, and the transmission request by the retransmission operation is increased. Traffic increases,
A dedicated terminal with the function of replacing the connection area identification code is required, and a terminal without this function cannot obtain the same service. If there is no terminal to receive the call, it is necessary to replace the identification code on the transmitting terminal side and perform a re-transmitting operation.

[0006] Further, it is necessary for the caller to perform re-transmission determination and redial button press operation.
Since the caller may feel annoying, there is a problem that if the terminal to be called does not exist in the area indicated by the connection area identification code that was first input by the caller, the caller needs to perform a redial instruction such as pressing the redial button. Occurs.

An object of the present invention is to provide a high speed communication between a calling terminal and a destination terminal without requiring any operation on the side of the calling party even when the terminal to be called does not exist in the area indicated by the connection area identification code. An object of the present invention is to provide a connection area automatic switching system capable of connection.

[0008]

According to the present invention, when there is no terminal to receive a call in the area indicated by the connection area identification code first input by the caller, the terminal is set in advance by the caller on the communication network side. The caller refers to a database as to whether or not to permit connection to a terminal to be received that is present in the connection area of the next candidate and, if permitted, performs a connection operation to the connection area of the next candidate, Notify the caller that connection to the next candidate connection area will be performed, including the specific fee structure, and suspend the connection operation if the caller performs rejection operation such as ending the call If it is not desired, a connection area automatic switching system is provided which notifies that there is no terminal to be received in the area indicated by the connection area identification code input first from the communication network side.

Further, according to the present invention, these means for notifying are not limited to only voice, but are performed by codes, and can be decoded on the terminal side.

[0010]

According to the present invention, when there is no terminal that should receive a call in the area indicated by the connection area identification code, the communication network performs an operation of connecting to the next candidate connection area, thereby reducing the operation of the caller. It is not necessary at all and before the connection operation to the next candidate is performed, the caller's reference to the database of whether or not he / she wants the operation set in advance makes it possible for the caller to consider the difference in the fee system, etc. The judgment can be reflected.

Further, according to the present invention, it is possible to notify the caller of the difference in the charge system due to the difference in the connection area by notifying that the connection operation to the next candidate is to be performed. At this point, it is possible to reflect the caller's judgment again.

Further, according to the present invention, the notification of the connection to the next candidate is performed by a code, thereby making it possible to minimize the increase in the connection time due to the notification, and to allow the communication network to connect to the connection area of the next candidate. By performing the above connection operation, it does not depend on the function of the calling terminal.

The exchange 20 includes a subscriber location registration information database 20a for managing location information of subscribing portable telephones including the portable telephones 40 and 41, and a subscriber including another communication network subscriber such as a caller of the telephone 10 or the like. It has a connection area automatic switching setting database 20b for setting whether or not reconnection to the connection area is permitted, as its constituent elements.

Here, the case where the automatic connection area switching database 20b is placed in the communication network of the connection destination terminal has been described. However, a configuration in which the connection area automatic switching database 20b is installed in the communication network of the caller is also possible. .

Although the case where the telephone 10 as the calling side is a fixed telephone has been described, a configuration in which the calling side is a mobile communication terminal such as a portable telephone is also possible.

Hereinafter, the operation of this embodiment will be described with reference to FIG.
This will be described with reference to FIG. First, the caller sets in advance in the connection area automatic switching setting database 20b from the telephone 10 whether connection operation to the next candidate connection area is permitted or not. The caller attempts to connect to the mobile phone 41 from the telephone 10 and dials the number of the mobile phone 41 with the identification code of the connection area 1 added. When the exchange 20 refers to the subscriber location registration information database 20a and recognizes that the mobile phone 41 does not exist in the connection area 1, it then refers to the connection area automatic switching setting database 20b,
The caller recognizes that the connection to the next candidate connection area is set to be permitted and starts a connection operation to the connection area 2 which is the next candidate connection area, and a specific fee structure. Is notified to the telephone 10 and the connection operation is started. If the caller performs a rejection operation such as ending the call using the telephone 10, the connection operation is interrupted. When there is no rejection operation, the connection with the mobile phone 41 via the base station 31 existing in the connection area 2 is completed.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a block diagram showing a communication network for performing charging management by a subscriber ID card to which the present invention is applied.

The operation of the second embodiment of the present invention will be described below. The subscriber who owns the subscriber ID card 50a dials the telephone number of the subscriber ID card 70a with the identification code of the connection area 1 added to the telephone 50 to connect to the subscriber who owns the subscriber ID card 70a. .

The exchange 20 refers to the subscriber location registration information database 20a, recognizes that the owner of the subscriber ID card 70a does not exist in the connection area 7, and then refers to the automatic connection switching setting database 20b to join. The owner of the user ID card 50a recognizes that the connection to the next candidate connection area is set, and starts the connection area 2 which is the next candidate connection area, and includes the fee system. The notification is sent to the telephone 50 and the connection operation is started.

Here, if the owner of the subscriber ID card 50a performs a rejection operation such as ending the call from the telephone 50, the connection operation is interrupted. If there is no rejection operation, the connection with the telephone 70 combined with the subscriber ID card 70a existing in the connection area 2 is completed.

[0024]

According to the present invention, since the reconnection operation to the next candidate connection area is determined and executed on the communication network infrastructure side, the operation time of the calling terminal and the operation time of the caller can be omitted. Therefore, even if there is no terminal to be received in the area indicated by the connection area identification code input first by the caller, reconnection to the next candidate connection area can be executed without operation of the caller side. Connection time can be reduced.

Further, according to the present invention, since the judgment and execution are performed on the communication network infrastructure side, there is no dependency on the function of the calling terminal. Therefore, the first effect can be equally given to all the transmitting terminals.
