DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of converting a code string received or received over a plurality of areas into a tone signal and transmitting the signal, or inputting and storing a plurality of code strings and converting the stored code string into a tone signal. The present invention relates to a radio selective calling receiver which can be converted into a signal and transmitted, and a method of controlling an auto dialer.

[0002]

2. Description of the Related Art The service area of a radio selective call receiver (commonly called a pager or pager) is usually a specific one.
Limited to one wireless zone. In contrast,
A service called "multi-area service" has been implemented that enables a user to receive a call even when moving between a plurality of wireless zones, such as a service area of a different radio selective call receiver.

[0003] However, when a user moves to an arbitrary place and receives such a service, it is necessary to register an area with a radio selective call receiver business operator that controls each service area.

As an example of such an area registration, a user of a radio selective call receiver first uses a telephone capable of transmitting a tone signal, and a call center or the like previously determined for each radio selective call receiver operator. Make a call to. Thereafter, the user sends a password, a current area number, and the like by a tone signal according to a predetermined procedure.

In order to simplify the area registration work, a tone dialer function is essential for a radio selective calling receiver. That is, by providing a function to sequentially and sequentially transmit a character string set in advance or a character string input by the user, when the user switches the area of the receiver, the telephone number or PIN of the above-mentioned call center, or The area number of the switching destination is displayed on the menu screen, and the area can be registered by one button operation.

Recent wireless selective call receivers have been enhanced with functions such as registering a telephone directory and a transmitted message. Further, in combination with a tone dialer function, a call receiver of the other party's receiver can be called with a simple button operation. Because you can send the number and the outgoing message,
The frequency of using the tone dialer function is increasing.

[0007]

By the way, the tone dialer function provided in the radio selective calling receiver is generally used in places where the user is away from home. Connectivity matters.

Needless to say, conditions such as the shape of the mouthpiece of the telephone, the characteristics of the microphone, and ambient noise are extremely varied. Therefore, if the sound pressure level of the tone signal sent from the tone dialer is constant, it is extremely difficult to make a good connection to all telephones.

The present invention has been made under such a background. When transmitting a tone signal corresponding to a code string such as a character / numeral / symbol or performing remote control by this tone signal, an extremely wide variety of types are provided. It is an object of the present invention to provide a radio selective calling receiver and an automatic dialer control method capable of ensuring high connectivity with a telephone.
