Automatic dialing method of mobile telephone using abbreviated or full number format

An automatic dialing method of a mobile telephone system linked to a mobile telephone network and having a send key for enabling an operator to send an origination message to the mobile telephone network upon depression, and an abbreviated dialing memory for storing a plurality of destination telephone numbers of selected subscribers said method comprising the steps of:

• determining whether one of a telephone number of a called subscriber and an abbreviated number corresponding to the telephone number is entered by the operator;
• sequentially storing the telephone number of the called subscriber in a buffer memory as each digit of the telephone number is being entered by the operator;
• determining whether a predetermined time period has expired after all digits of the telephone number have been entered by the operator and sequentially stored in said buffer memory;
• automatically dialing the telephone number of the called subscriber for establishing a connection to the mobile telephone network upon expiration of said predetermined time period, without depression of said send key;
• storing the abbreviated number corresponding to the telephone number of the called subscriber in said buffer memory, when the abbreviated number corresponding to the telephone number has been entered by the operator;
• determining whether said predetermined time period has expired after all digits of the abbreviated number have been stored in said buffer memory;
• accessing said abbreviated dialing memory to reproduce the telephone number of the called subscriber stored in said abbreviated dialing memory corresponding to the abbreviated number stored in said buffer memory, and automatically dialing the telephone number of the called subscriber for establishing a connection to the mobile telephone network upon expiration of said predetermined time period, without depression of said send key;
• displaying the telephone number of the called subscriber while dialing to establish a connection to the mobile telephone network;
• and
• immediately dialing the telephone number of the called subscriber in accordance with the input key data sequentially stored in said first memory in response to depression of said send key, regardless of whether the next key data is input within said predetermined time period.

A dialing method in a radio mobile telephone linked to a mobile telephone network having a first memory, a second memory for storing a plurality of destination telephone numbers of selected subscribers and abbreviated numbers corresponding to the destination telephone numbers, and a key input unit with at least a send key for enabling an operator to send an origination message to the mobile telephone network upon depression, said method comprising the steps of:

• detecting whether key data is input by the operator through said key input unit, and analyzing whether the input key data indicates one of dial key data and abbreviated dial key data;
• when the input key data indicates said dial key data representing each digit of a telephone number of a called subscriber, storing the input key data in said first memory;
• determining whether the number of digits represented by the input key data is less than a predetermined number;
• returning to detect whether next key data is input by the operator, when the number of digits input by the dial key data is less than said predetermined number;
• determining whether the next key data is input within a predetermined time period when the number of digits input by the dial key data is not less than said predetermined number;
• returning to detect whether additional key data is input by the operator, when the next key data is input within the predetermined time period;
• automatically dialing the telephone number of the called subscriber in accordance with the input key data sequentially stored in said first memory, when the next key data is not input within the predetermined time period, without depression of said send key;
• alternatively, when the input key data indicates said abbreviated dial key data representing an abbreviated number of the telephone number of said called subscriber, storing the abbreviated number corresponding to the telephone number of the called subscriber in said first memory;
• determining whether the next key data is input within said predetermined time period, after the abbreviated dial key data has been stored in said first memory;
• and
• accessing said second memory to reproduce the telephone number of the called subscriber stored in said second memory corresponding to the abbreviated number stored in said first memory, and automatically dialing the telephone number of the called subscriber for establishing a connection to the mobile telephone network, when the next key data is not input within said predetermined time period, without depression of said send key.

• determining whether the number of digits represented by the input key data is less than a predetermined number;
• returning to detect whether next key data is input by the operator, when the number of digits input by the dial key data is less than said predetermined number;
• determining whether a generating time of current key data as input by the operator is within a predetermined time, when the number of digits input by the dial key data is not less than said predetermined number;
• returning to detect whether next key data is input by the operator, when the generating time of the current key data as input by the operator is within said predetermined time;
• and
• automatically dialing the telephone number of the called subscriber in accordance with the input key data sequentially stored in said first memory, without depression of said send key, when the generating time of the current key data is not within said predetermined time.

A mobile telephone system linked to a mobile telephone network, comprising:

• a first memory;
• a second memory storing pre-registered telephone numbers of selected subscribers and abbreviated numbers corresponding to the telephone numbers;
• a key input unit having a keypad for allowing an operator to input telephone numbers, abbreviated numbers corresponding to the telephone numbers, and at least a send key for enabling the operator to send an origination message to the mobile telephone network upon depression and;
• a display unit for displaying the telephone numbers and the abbreviated numbers input by the operator;
• a controller for controlling an automatic dialing of the mobile telephone system by:
• determining whether one of a telephone number of a called subscriber and an abbreviated number corresponding to the telephone number is entered by the operator;
• sequentially storing the telephone number of the called subscriber in said first memory as each digit of the telephone number is being entered by the operator;
• determining whether a predetermined time period has expired after all digits of the telephone number have been entered by the operator and sequentially stored in said first memory;
• and
• automatically dialing the telephone number of the called subscriber for establishing a connection to the mobile telephone network upon expiration of the predetermined time period, without depression of said send key.
