Abstract

A dialing method for a telephone system begins by receiving a caller indentification (i.e., telephone number) of a party calling the telephone system. The received caller identification is then stored in a control buffer of the telephone system. A control unit of the telephone system determines whether the caller identification stored in the control buffer is identical to one of a plurality of existing caller identifications stored in a memory of the telephone system. When the caller identification stored in the control buffer is identical to one of the existing caller identifications stored in the memory, the existing caller identification that is identical to the caller identification is deleted from the memory. The caller identification is then transferred from the control buffer to the memory, and stored in the memory according to a last in first out rule. The caller identification is displayed on a display unit of the telephone system in response to a first input of a search key. Then, the telephone number corresponding to the caller identification is automatically dialed in response to input of a start key.

Claims

1. A dialing method for a telephone system using a caller identification, comprising steps of:

receiving, in response to an incoming call, a telephone number of a party calling said telephone system as a caller identification from said incoming call interposed between ring signals;

automatically registering said caller identification, while said ring signals indicative of said incoming call are being received, in a memory of said telephone system according to a last in first out rule by;

temporarily storing said caller identification in a temporary storage unit of said telephone system;

comparing said caller identification stored in said temporary storage unit with existing caller identifications registered in said memory; and

registering said caller identification in said memory according to said last in first out rule by transferring said caller identification from said temporary storage unit to said memory, and when said caller identification is identical to one of said existing caller identifications registered in said memory, deleting the one of said existing

caller identifications that is identical to said caller identification from said memory;

after said ring signals are terminated, and said caller identification is registered in said memory, searching said memory for said caller identification in response to input of a search key from an operational panel of said telephone system; and

then

after said caller identification is searched, automatically dialing said telephone number corresponding to said caller identification in response to input of a start key from said operational panel of said telephone system.

2. The dialing method of claim 1, wherein said step of automatically registering said caller identification comprises substeps of:

temporarily storing said caller identification in a temporary storage unit of said telephone system;

comparing said caller identification stored in said temporary storage unit with existing caller identifications registered in said memory; and

registering said caller identification in said memory according to said last in first out rule by transferring said caller identification from said temporary storage unit to said memory.

3. The dialing method of claim 2, wherein said step of searching comprises substeps of:

providing display of said caller identification on a display unit of said telephone system in response to input of said search key; and

sequentially displaying said existing caller identifications registered in said memory via successive inputs of said search key.

4. The dialing method of claim 1, wherein said step of searching comprises substeps of:

providing a visual display of said caller identification on a display unit of said telephone system in response to input of said search key; and

sequentially displaying said existing caller identifications registered in said memory on said display unit via successive inputs of said search key.

5. The dialing method of claim 3, wherein said step of dialing said telephone number is automatically performed in response to input of said start key, while said telephone number is displayed on said display unit.

6. The dialing method of claim 4, wherein said step of dialing said telephone number is automatically performed in response to input of said start key, while said telephone number is displayed on said display unit.

7. The dialing method of claim 1, wherein said caller identification is received between said ring signals during said incoming call to said telephone system and temporarily stored in said temporary storage unit, and subsequently stored in said memory when said caller identification does not correspond to any existing caller identifications registered in said memory.

8. The dialing method of claim 5, wherein said caller identification is received between said ring signals during said incoming call to said telephone system and temporarily stored in said temporary storage unit, and subsequently stored in said memory when said caller identification does not correspond to any existing caller identifications registered in said memory.

9. The dialing method of claim 6, wherein said caller identification is received between said ring signals during said incoming call to said telephone system and temporarily stored in said temporary storage unit, and subsequently stored in said memory when said caller identification does not correspond to any existing caller identifications registered in said memory.

10. A dialing method for a telephone system, comprising steps of:

receiving, in response to an incoming call from a central office exchange, a telephone number of a party calling said telephone system as a caller identification from said incoming call interposed between ring signals;

storing said caller identification in a control buffer of said telephone system;

determining whether said caller identification stored in said control buffer is identical to one of a plurality of existing caller identifications stored in a memory of said telephone system;

when said caller identification stored in said control buffer is identical to one of said existing caller identifications stored in said memory, deleting the one of said existing caller identifications that is identical to said caller identification from said memory;

transferring said caller identification from said control buffer to said memory, and storing said caller identification in said memory according to a last in first out rule;

providing a visual display of said caller identification on a display unit of said telephone system in response to input of a search key; and

then

automatically dialing said telephone number corresponding to said caller identification in response to input of a start key.

11. The dialing method of claim 10, wherein said caller identification is received between said ring signals during said incoming call to said telephone system and temporarily stored in said control buffer, and then stored in said memory when said caller identification does not correspond to any existing caller identifications registered in said memory.

12. A telephone system, comprising:

a line signal detecting unit for detecting a caller identification comprising a telephone number of a caller from an incoming call interposed between ring signals;

a control unit for controlling an overall operation of said telephone system, said control unit receiving said caller identification from said line signal detecting unit and storing said caller identification in a buffer of said control unit;

a key input unit having a plurality of keys for providing key inputs to said control unit, said keys comprising a search key and a start key;

a display unit for providing visual displays in response to a control of said control unit;

a memory for storing existing caller identifications; and

said control unit determining whether said caller identification stored in said buffer is identical to one of said existing caller identifications stored in said memory, transferring said caller identification from said buffer to said memory, storing said caller identification in said memory according to a last in first out rule, enabling a visual display of said caller identification on said display unit in response to input of said search key, and then automatically dialing said telephone number corresponding to said caller identification in response to input of said start key, and deleting one of said existing caller identifications that is identical to said caller identification from said memory, when said caller identification stored in said buffer is identical to one of said existing caller identifications stored in said memory.

13. The telephone system of claim 12, further comprising a ring detecting unit for detecting ring signals from a public switched telephone network, and providing said ring signals to said control unit.
