Abstract

In a portable communication device, such as a cellular phone, an identification data signal which includes both a directory number and a mail number of the other party is automatically registered in a memory of the portable communication device during a pause period in conversation. Both a bearer'"'"'s directory number and mail address are automatically also transmitted to the other party during the pause period. This dispenses with manual complex operation for registering the directory number and the mail address in each portable communication device.

Claims

1. A portable communication device for use in carrying out communication with the other party through a radio channel, comprising:

a receiver unit for receiving a reception communication signal together with an identification data signal identifying the other party; and

a first registration section for automatically registering the identification data signal by distinguishing the identification data signal from the reception communication data signal.

2. A portable communication device as claimed in claim 1, further comprising:

a first control section for controlling the receiver unit and the first registration section to distinguish between the reception communication data signal and the identification data signal to selectively store only the identification data signal in the first registration section.

3. A portable communication device as claimed in claim 2, wherein the identification data signal is arranged within a pause period of the reception communication data signal;

the first control section comprising;

a detection unit for detecting the identification data signal by monitoring the pause period of the reception communication data signal; and

a delivery unit for delivering the identification data signal detected by the detection unit to store the same into the first registration section.

4. A portable communication device as claimed in claim 1, further comprising:

a second registration section for registering a bearer'"'"'s identification data signal identifying a bearer; and

a transmitter unit for automatically transmitting the bearer'"'"'s data signal.

5. A portable communication device as claimed in claim 4, further comprising:

a voice signal detection unit for detecting a voice signal to send the voice signal detected to the transmitter unit.

6. A portable communication device as claimed in claim 5, wherein the voice signal detection unit comprises:

a pause detecting section for detecting a pause period from the voice signal to produce a pause detection signal representative of the pause period when the voice signal is absent during the communication;

the first control section further comprising;

a transmission data selection unit for arranging the bearer'"'"'s identification data signal instead of the voice signal when the pause period is detected.

7. A portable communication device as claimed in claim 1, which is operable as a portable digital assistance (PDA) device.

8. A portable communication device as claimed in claim 1, which is operable as a cellular phone.

9. A portable communication device as claimed in claim 8, which is operable as a cellular phone;

the portable communication device further comprising;

comparing means for comparing the caller'"'"'s identification data signal with registered personal identification data signals in the first control section, to detect whether or not the identification data signal is coincident with either one of the registered personal identification data signals; and

registering means for updating the registered personal identification data signals by delivering the identification data signal to the first registration section only when the identification data signal is incoincident with each of the registered personal identification data signals.

10. A portable communication device as claimed in claim 9, wherein the identification data signal includes both a directory number and a mail address all of which are assigned to the other party.

11. A portable communication device as claimed in claim 9, further comprising:

receiving means for receiving a bearer'"'"'s voice signal to detect a pause period within the bearer'"'"'s voice signal and to produce a pause detection signal representative of the pause period;

registering means for registering bearer'"'"'s identification data signal; and

processing means for processing the bearer'"'"'s voice signal and the pause detecting signal to insert the bearer'"'"'s identification data signal into the bearer'"'"'s voice signal within the pause detection signal.

12. A portable communication device as claimed in claim 11, wherein each of the identification data signal and the bearer'"'"'s identification data signals is separately arranged instead of the voice signal within a traffic channel field.
