Abstract

A device for ring tone output. The device comprises a phone speaker, a ringing speaker, a receiver, a switching device and a micro-controller. The receiver acquires audio data via a traffic channel. The audio data comprises a ring tone. The switching device receives the ring tone and selectively transmits the ring tone to the phone speaker and the ringing speaker. The micro-controller directs the switching device to transmit the ring tone to the ringing speaker.

Claims

1. A mobile unit for communicating with a base station, the base station allocating a traffic channel and a control channel after receiving a communication request, the mobile unit comprising:

a phone speaker;

a ringing speaker;

a receiver receiving an incoming call signal via the control channel, and an audio data via the traffic channel;

a switching device coupled to the receiver, configured to receive the audio data and selectively transmit the audio data to the phone speaker and the ringing speaker; and

a micro-controller coupled to the switching device, after receiving the incoming call signal, the micro-controller configured to control the switching device to receive the audio data via the audio channel and concurrently transmit the audio data to the ringing speaker before the incoming call is answered, and after receiving a signal for answering the incoming call signal, the micro-controller configured to control the switching device to transmit the audio data to the phone speaker.

2. The mobile unit as claimed in claim 1, wherein the receiver further comprises:

a demodulator configured to receive the audio data via the traffic channel and demodulate the audio data to digital data;

a digital signal processor coupled to the demodulator, configured to process the digital data; and

a digital-to-analog converter (DAC) coupled to the digital signal processor, configured to receive and convert output of the digital signal processor to the ring tone.

3. The mobile unit as claimed in claim 1, wherein the receiver further comprises a scratch memory, coupling to the digital signal processor, configured to store the output of the digital signal processor temporarily.

4. The mobile unit as claimed in claim 3, wherein the digital signal processor repeatedly refreshes the digital data in the scratch memory until the signal from a function key is detected.

5. The mobile unit as claimed in claim 3, wherein the digital signal processor erases the digital data of the scratch memory after detecting the signal from a function key.

6. The mobile unit as claimed in claim 1, is a cellular phone.

7. The mobile unit as claimed in claim 1, further comprising:

a function key for generating the signal when the function key is pressed.

8. The mobile unit as claimed in claim 7, wherein the micro-controller transmits a connection signal via a control channel after detecting a press signal from the function key.

15. The mobile unit as claimed in claim 1, wherein the audio data transmitting to the ringing speaker is the ring tone.

17. The mobile unit as claimed in claim 15, wherein the ring tone is initially stored in a melody database of a base station system.

9. A method for ring tone output in a wireless telephony network comprising a base station system and a mobile station having a phone speaker and a ringing speaker, the method comprising the steps of:

(a) the base station system allocating a traffic channel and a control channel after receiving a communication request;

(b) receiving an incoming call signal via the control channel for a call connection, and the audio data via the traffic channel from the base station system, wherein the audio data comprises a ring tone at beginning of the call connection;

(c) concurrently outputting the ring tone to the ringing speaker after receiving the incoming call signal from the control channel; and

(d) transmitting the audio data to the phone speaker after detecting a press signal from a function key of the mobile station, subsequent to the incoming call signal.

10. The method as claimed in claim 9, wherein the mobile station is a cellular phone.

11. The method as claimed in claim 9, wherein the method further comprises the steps of:

(e) generating the press signal; and

(f) transmitting a connection signal to the base station system via a control channel.

18. The method as claimed in claim 9, wherein the ring tone is initially stored in a melody database of the base station system.

12. A method for a ring tone output utilized in a mobile station communicating with a base station, comprising:

(a) the base station allocating a traffic channel and a control channel after receiving a communication request;

(b) receiving an incoming call signal for a call connection from the control channel;

(c) receiving audio data via the traffic channel;

(d) concurrently acquiring a ring tone from the audio data at beginning of call connection, when the audio data including the ring tone; and

(e) concurrently transmitting the ring tone to a ringing speaker of the mobile station.

13. The method as claimed in claim 12, wherein the mobile station is a cellular phone.

14. The method as claimed in claim 12, wherein the method further comprises the steps of:

(f) completing the ring tone transmission after detecting a press signal from a function key of the mobile station, subsequent to the incoming call signal; and

(g) transmitting a connection signal to a base station system via the control channel.

16. The method as claimed in claim 14 further comprising:

(h) transmitting the audio data to a phone speaker after detecting the press signal.

19. The method as claimed in claim 12, further comprising the steps of:

the base station acquiring the ring tone from a melody database according to a configuration setting, the ring tone initially storing in the melody database.
