Next, the operation of the device having the above configuration will be described with reference to the flowchart shown in FIG. 3.

First, when the portable telephone is turned on (step ST1), when the user inputs the setting key 31a of the key input unit 31 (step ST2), the controller 33 enters the priority connection setting mode. In addition to the switching, the display unit 22 displays the state (ST3 step).

However, when there is an input of the function execution key 31b for executing the connection to the set service number instead of the setting key 31a for setting the service number through the key input unit 31 in the step ST2 (step ST4). The control unit 33 reads, for example, the 82 service number stored in the setting data storage unit 32 and wirelessly transmits a dialing signal corresponding thereto (step ST5).

Subsequently, when a call is made with the service number which attempted to connect with the call (step ST6), if there is an input of a telephone number by a subsequent user, the control section 33 executes normal control processing related to the call by dialing to that number. And step ST8).

However, if the service number is attempted to connect to the call and the service number is not connected to the call due to the congestion of the call volume, a busy tone signal or a busy tone is received. The busy number is received through the busy tone detector 35. If it is determined that the tone signal is detected and no connection is made to the call (step ST6), the control section 33 switches to the original area code mode, for example, 2, to perform normal control processing related to the call and terminate ( ST7 to ST8 steps).

In addition, in step ST2, if there is no input of the setting key 31a or the function execution key 31b of the key input unit 31, the control unit 33 is a conventional mobile phone such as a dialing function for calling or other functions. The control process is carried out and ends (ST8 step).

However, when the number data of 82 is input through the numeric keys (not shown) of the key input unit 31 in step ST3 (step ST11), the control unit 33 sets the input data to the setting data storage unit. By storing in 32, the service number of the priority connection dialing is registered (ST12 step).

Then, the control unit 33 sets the priority connection mode to the mode state storage unit 34, so that the subsequent mobile phone is dialed by the user after the priority connection dialing is executed when the power is turned on. .

On the other hand, in order to cancel the state in which the priority connection service is registered as described above, the function is canceled by inputting a mode release key (not shown) of the key input unit 31.

That is, according to an embodiment of the present invention, if the user presses a function key to turn on the portable telephone for a call, priority is first dialed to a registered service number and then dialed to the called phone number. This will be greatly improved.

The present invention is not limited to the above embodiments and various modifications can be made without departing from the technical gist of the present invention.

As described above, according to the present invention, it is possible to realize a portable telephone capable of performing dialing first with the added service number by adding the service number set by the user.
