ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a directory dialing telephone set which is provided with a directory for storing a plurality of telephone numbers and which has functions for executing calling or dialing of a telephone number in a telephone network which has been stored in the directory.
DESCRIPTION OF THE PRIOR ART
These days, many of the telephone sets on the market are provided with functions for storing a plurality of telephone numbers in a directory and executing dialing (calling) of a telephone number which has been stored in the directory (hereafter, such a telephone set will be referred to as a “directory dialing telephone set”). The user selects a telephone number from the directory and dials the selected telephone number with easy operation such as pushing one or more buttons.
When a telephone number should be registered in the directory of such a directory dialing telephone set, the user usually selects a registration mode of the telephone set, which is different from the ordinary mode for conversation, by pushing a button etc. Meanwhile, as disclosed in Japanese Patent Application Laid-Open No.SH063-278451, there has been proposed a directory dialing telephone set which is provided with functions for registering telephone numbers in its directory semi automatically. The telephone numbers which are registered by the directory dialing telephone set include telephone numbers which have been dialed by the user for calling and telephone numbers of calling parties (i.e. calling numbers) which have been informed by the telephone network in services such as “calling number identification presentation” etc. The directory dialing telephone set inquires of the user whether or not the user intends to register the telephone number (i.e. the telephone number which the user dialed or the telephone number of a calling party which has been informed by the telephone network) if the telephone number has not been registered in the directory yet. The inquiry is executed by the directory dialing telephone set on each telephone call (calling and reception of a call), and the telephone number is registered in the directory if the user intended to register the telephone number and requested the registration by pushing a button etc.
However, such a directory dialing telephone set executes the inquiry depending on the result of the simple judgment on whether or not the current telephone number (i.e. the telephone number which has just been dialed by the user for calling or the telephone number of a calling party which has just been informed by the telephone network) has already been registered in the directory, and thus the inquiry is executed even in the case where the telephone number is dialed by the user very rarely (i.e. even in the case where it is almost clear that the telephone number will not be registered by the user), or even in the case where the user received a call from an undesired calling party.
As described above, conventional directory dialing telephone sets which are provided with functions for registering telephone numbers in their directories require the user to spend time and execute some troublesome operation regardless of the priority of the telephone number.
SUMMARY OF THE INVENTION
It is therefore the primary object of the present invention to provide a directory dialing telephone set provided with functions for registering telephone numbers in its directory, by which the user is released from the troublesome operation with regard to telephone numbers that will not be registered, for example, when the telephone number dialed by the user is a rarely used number, when the user received a call from an undesired calling party, etc., and the user can register necessary telephone numbers in the directory efficiently and with a minimum of effort.
In accordance with a first aspect of the present invention, there is provided a directory dialing telephone set which is provided with a directory storage means for storing a directory including a plurality of telephone numbers and which has functions for executing dialing of a telephone number which has been selected by the user from the telephone numbers stored in the directory storage means, comprising a telephone call frequency judgment means and a directory storage control means. The telephone call frequency judgment means judges whether or not frequency of telephone calls concerning a current telephone number, which have just been dialed by the user or informed via the telephone network, is higher than predetermined frequency. And the directory storage control means executes control concerning storage of the current telephone number in the directory of the directory storage means if the current telephone number has not been stored in the directory of the directory storage means yet and the telephone call frequency judgment means judged that the frequency of telephone calls concerning the current telephone number is higher than the predetermined frequency.
In accordance with a second aspect of the present invention, in the first aspect, the directory storage control means inquires of the user whether or not the user intends to store the current telephone number in the directory of the directory storage means if the current telephone number has not been stored in the directory of the directory storage means yet and the telephone call frequency judgment means judged that the frequency of telephone calls concerning the current telephone number is higher than the predetermined frequency, and stores the current telephone number in the directory of the directory storage means if the user requested to store the current telephone number.
In accordance with a third aspect of the present invention, in the first aspect, the directory storage control means stores the current telephone number in the directory of the directory storage means if the current telephone number has not been stored in the directory of the directory storage means yet and the telephone call frequency judgment means judged that the frequency of telephone calls concerning the current telephone number is higher than the predetermined frequency.
In accordance with a first aspect of the present invention, there is provided a directory dialing telephone set which is provided with a directory storage means for storing a directory including a plurality of telephone numbers and which has functions for executing dialing of a telephone number which has been selected by the user from the telephone numbers stored in the directory storage means, comprising a telephone number temporary storage means, a counter means, a searching means, and a directory storage control means. The telephone number temporary storage means temporarily stores a predetermined number of telephone numbers which have been dialed by the user and telephone numbers of calling parties which have been informed via the telephone network. The counter means counts the number of times of storage of a current telephone number, which have just been dialed by the user or informed via the telephone network, that exist in the telephone number temporary storage means. The searching means searches the directory storage means for the current telephone number and judges whether or not the current telephone number has already been stored in the directory of the directory storage means. And the directory storage control means executes control concerning storage of the current telephone number in the directory of the directory storage means if the number of times which has been counted by the counter means is larger than a predetermined threshold number and the searching means judged that the current telephone number has not been stored in the directory of the directory storage means yet.
In accordance with a fifth aspect of the present invention, in the fourth aspect, the directory storage control means inquires of the user whether or not the user intends to store the current telephone number in the directory of the directory storage means if the number of times which has been counted by the count
