Abstract

In a mobile communication system, each mobile terminal as well as the base station are provided with a registration memory for storing abbreviated dialing data which comprises at least one pair of an abbreviated number and an identification number corresponding to the abbreviated number. The abbreviated dialing data is stored into the registration memory of a first mobile terminal by the user operating a keypads The stored abbreviated dialing data is transferred from the first mobile terminal to the base station. When a second mobile terminal requests the abbreviated dialing data stored in the base station, the base station transmits the abbreviated dialing data to the second mobile terminal. In this manner, the abbreviated dialing data is transferred from a mobile terminal to the base station and then from the base station to another mobile terminal.

Claims

1. A method for registering abbreviated dialing data in a mobile communication system comprising at least one base station and a plurality of mobile terminals, said method comprising the steps of:

a) registering said abbreviated dialing data in a first mobile terminal;

b) transferring said abbreviated dialing data from said first mobile terminal to a base station in response to a first transfer request of said first mobile terminal for transfer of said abbreviated dialing data to said base station, said first mobile terminal being located within a service zone of said base station;

c) registering said abbreviated dialing data in said base station;

d) transferring said abbreviated dialing data from said base station to a second mobile terminal in response to a second transfer request of said second mobile terminal for transfer of said abbreviated dialing data to said second mobile terminal, said second mobile terminal being located within said service zone of said base station; and

e) registering said abbreviated dialing data in said second mobile terminal.

2. The method according to claim 1, wherein the step (a) comprises the steps of:

entering said abbreviated dialing data in said first mobile terminal by keying, said abbreviated dialing data comprising at least one pair of an abbreviated number and an identification number corresponding to said abbreviated number; and

storing said abbreviated dialing data into a first registration memory provided in said first mobile terminal.

3. The method according to claim 1, wherein the step (b) comprising the steps of:

at said first mobile terminal,

transmitting said first transfer request to said base station;

receiving an acknowledgment of said first transfer request from said base station; and

transmitting said abbreviated dialing data to said base station.

4. The method according to claim 3, wherein the step (b) further comprises the steps of:

at said base station,

receiving said first transfer request from said first mobile terminal;

transmitting said acknowledgment of said first transfer request to said first mobile terminal; and

receiving said abbreviated dialing data from said first mobile terminal.

5. The method according to claim 1, wherein the step (c) comprises a step of storing said abbreviated dialing data into a second registration memory provided in said base station.

6. The method according to claim 1, wherein the step (d) comprising the steps of:

at said second mobile terminal,

transmitting said second transfer request to said base station;

receiving an acknowledgment of said second transfer request from said base station; and

receiving said abbreviated dialing data from said base station.

7. The method according to claim 6, wherein the step (d) further comprises the steps of:

at said base station,

receiving said second transfer request from said second mobile terminal;

transmitting said acknowledgment of said second transfer request to said second mobile terminal; and

transmitting said abbreviated dialing data to said second mobile terminal.

8. The method according to claim 1, wherein the step (e) comprises a step of storing said abbreviated dialing data into a third registration memory provided in said second mobile terminal.

9. The method according to claim 1, wherein said base station is placed indoors and is connected to a switching system through a subscriber line, and said mobile terminal is a digital cordless communication terminal.

10. The method according to claim 1, wherein said base station is placed outdoors and is connected to an ISDN line, and said mobile terminal is a digital cordless communication terminal.

11. The method according to claim 1, wherein said mobile terminal is a digital cordless telephone.

12. The method according to claim 11, wherein said mobile terminal is a personal handy phone.

13. A system comprising:

at least one base station connected to a communication network and a plurality of mobile terminals located within a service area of said base station, said base station comprising;

first storage means for storing abbreviated dialing data;

first communication means for making communications with said plurality of mobile terminals through radio channels; and

first control means for controlling said first storage means and said first communication means such that said abbreviated dialing data is received from a mobile terminal and is stored into said first storage means and said abbreviated dialing data is read out from said first storage means and is transmitted to another mobile terminal, and

each one of said plurality of mobile terminals comprising;

input means for inputting said abbreviated dialing data by keying;

second storage means for storing said abbreviated dialing data;

second communication means for making a communication with said base station through a predetermined one of said radio channels; and

second control means for controlling said second storage means and said second communication means such that a first transfer request for transfer of said abbreviated dialing data to said base station is transmitted to said base station and said abbreviated dialing data is transmitted to said base station through the predetermined radio channel when receiving a first acknowledgment of said first transfer request from said base station, and further controlling said second storage means and said second communication means such that a second transfer request for transfer of said abbreviated dialing data from said base station is transmitted to said base station and said abbreviated dialing data is received from said base station through the predetermined radio channel after receiving a second acknowledgment of said second transfer request from said base station.

14. The system according to claim 13, wherein said base station is placed indoors and is connected to a switching system through a subscriber line, and each of said plurality of mobile terminals is a digital cordless communication terminal.

15. The system according to claim 13, wherein said base station is placed indoors and is connected to an ISDN line, and each of said plurality of mobile terminals is a digital cordless communication terminal.

16. The system according to claim 13, wherein each of said plurality of mobile terminals is a digital cordless telephone.

17. The system according to claim 16, wherein each of said plurality of mobile terminals is a personal handy phone.
