Description

  The present invention relates to a dialing method for a mobile phone, a program for realizing the method, and an external connection device for a mobile phone, and more specifically, a called party telephone number input by key operation or a mobile phone When making a call to the destination telephone number selected from the telephone numbers stored in advance in the memory, a preset number (referred to as “preset number” in the present invention) is added before the destination telephone number. The present invention relates to a dial transmission control method for a mobile phone that causes dialing to be performed, a program for realizing the method, and an external connection device for a mobile phone.

  There is a so-called “attachment” as an external connection device that controls a dial transmission of a mobile phone to perform a predetermined dial operation by connecting to an external connection terminal provided on the mobile phone.

  This attachment is connected to an external connection terminal of the mobile phone (usually provided at a portion to which the connector of the charger is connected when the battery of the mobile phone is charged), thereby the memory of the attachment. It functions as an auto dialer that automatically makes calls to a predetermined telephone number stored in advance, and includes a power source such as a button battery, a ROM such as a flash memory, and a connector that can be connected to a connection terminal of the mobile phone. ing.

  In this attachment ROM, when the connector of the attachment is connected to the external connection terminal of the mobile phone, a control signal is output to the mobile phone via the external connection terminal described above to put the mobile phone in an “on-hook” state. In addition, a program for sending a telephone number stored in advance in the ROM and causing the cellular phone to dial the number is stored.

  Such an attachment is, for example, distributed by a non-life insurance company to, for example, a car insurance policyholder, and when the insurance subscriber connects this attachment to a mobile phone in the event of an accident, the mobile phone is Automatic call to the company's emergency call center, etc., which allows insurance subscribers to call the emergency call center, etc. without having to enter the phone number by operating the operation keys provided on the mobile phone It is configured to be able to.

  By the way, with the widespread use of mobile phones, communication services that can be used in mobile phones are diversified. For example, various high-value-added telecommunication services using a complex network by connecting a public telephone network and a dedicated line are available. Provision of various other communication services.

  As an example, by making a service that makes it possible to make an international call directly from a mobile phone, or by connecting the mobile phone to a phone on the receiving side via a telephone switch set by a type 2 communication carrier, Prevents the telephone number and call location information of the caller's mobile phone from being recorded or learned on the caller's phone, or connects to the caller's phone via a relatively inexpensive communication line. As a result, a communication service using a communication network or a composite network that can keep communication costs low can be provided.

  In order to receive the provision of such communication services, the called party is called via the above-mentioned telephone exchange set up by a type 2 communication carrier, etc., called “communication center”, “call center”, “access point”, etc. It is necessary to make a connection with the telephone, and in order to make a connection via such a telephone exchange, the user once gives the number given to the telephone exchange from the mobile telephone (for example, 4 starting with “00”). After dialing a digit number or other telephone number) and establishing a connection with the above-mentioned telephone exchange, an operation to input / send the telephone number of the called party is requested, or the called party telephone It is required to add the number assigned to the above-mentioned telephone exchange before dialing and dialing, and the work is complicated.

  In this way, for example, in order to receive provision of a communication service provided by the type 2 communication carrier, it is necessary to dial a larger number than in the case of simply inputting the incoming side telephone number.

  Therefore, in order to eliminate the burden on the user and the complexity of the dialing operation, the attachment to the telephone exchange can be connected by using the attachment that stores the number assigned to the telephone exchange. It has also been proposed to perform automatic transmission by wearing (see Non-Patent Document 1 and Non-Patent Document 2).

  As an example, in Non-Patent Document 1, by making a call to the receiving side telephone via a telephone exchange installed by the communication service provider, the telephone number of the calling side mobile phone and the location information Instead of the telephone number and the location information of the telephone exchange, the communication service can conceal the phone number and the location information of the caller. This is a service that enables an inexpensive international call through an IP telephone line connected to the telephone exchange through a telephone exchange installed by the provider.

Prior art document information of the present invention includes the following.
“Mask Call” (http://www.suimu.com/prepaid/fukumen/index.html) `` Portable dialer Pocketline '' (http://www.kinmirai.net/pocketline/pocketline.html)

  As described above, by using the attachment that stores the number assigned to the telephone switchboard, the mobile phone automatically makes a call to the number stored in the attachment simply by connecting the attachment to the external connection terminal of the mobile phone. Therefore, when a user of a communication service as described above inputs a number assigned to a telephone exchange by operating an operation key or the like, or registers a telephone number in an “address book” or the like provided in a mobile phone. In addition, the connection with the telephone exchange can be established without adding the number assigned to the above-mentioned telephone exchange or the like to the beginning of the number to be registered.

  Therefore, after such a connection is established, the user simply inputs the telephone number on the receiving side by key operation of the mobile phone or calls and sends the telephone number registered in the mobile phone in advance. Using the communication service, a call can be made to the called telephone.

  By the way, when a call is made via a telephone exchange as described above, the call charge between the calling-side mobile phone and the called-side telephone is based on the call charge from the calling-side mobile phone to the telephone exchange, and from the telephone exchange. This is the sum of the call charges to the called telephone.

  The call charge between the originating mobile phone and the telephone exchange is determined from the time when the connection between the originating mobile phone and the telephone exchange is established, regardless of whether or not the connection between the telephone exchange and the incoming telephone is established. appear.

  Therefore, when the mobile phone immediately makes a call to the telephone exchange by mounting the above-mentioned attachment on the mobile phone, the incoming phone is used even though the user's purpose is a call with the incoming phone. Before the connection with the user is established, for example, while the user is inputting the telephone number of the called telephone, the call charge is counted.

  Also, for example, even when the user does not enter the telephone number of the called telephone, or cancels such input work halfway and does not call the called telephone, Call charges between the calling mobile phone and the telephone switch that occurred between the connection between the mobile phone and the telephone switch until the work is canceled will be used directly or indirectly. Will be borne by the person.

  Furthermore, when the attachment detects the connection to the mobile phone, it immediately starts outputting a signal for instructing the mobile phone to dial the stored number. However, the attachment is electrically connected to the mobile phone. If the connection is detected, the output of the control signal is started even if the connector is not completely attached to the connection terminal of the mobile phone and the electrical connection is unstable. It may start.

  For this reason, the connection between the two may be disconnected before the external connection terminal is completely inserted into the connector, and the signal input from the attachment to the malformed telephone may be incomplete. .

  As described above, when the signal input to the mobile phone is incomplete, the mobile phone does not start the dialing operation, or performs incomplete dialing in accordance with the partially dropped signal. In some cases, the telephone exchange cannot be connected, and as a result, the called telephone cannot be called.

  Accordingly, an object of the present invention is made to eliminate the drawbacks in the prior art described above. For example, when communication is performed via a telephone exchange installed by a second-class communication carrier or the like, a receiving-side telephone is set. A mobile phone that can prevent call charges from being generated while entering the telephone number of the telephone or when the input is terminated and the work is terminated, and can effectively prevent incomplete calls from occurring It is an object of the present invention to provide a transmission control method, a program for realizing the method, and an external connector.
