Mobile communication terminal and automatic answering method thereof
First Claim
1. A method for automatically answering a mobile communication terminal which has an automatic answering function and is provided with a plurality of different audio codecs, the method comprising the steps of:
- performing a call set-up when a call signal is received;
determining if the automatic answering function is set;
reading a pre-stored automatic answering message if the automatic answering function is set;
selecting an encoder of a codec which corresponds to a coding type of the call signal received during the call set-up; and
encoding the read automatic answering message through the encoder.

Abstract
Disclosed is a mobile communication terminal of a mobile communication system using a plurality of different codecs and an automatic answering method thereof which can perform an automatic answering function with a single type of an automatic answering message without the necessity of storing automatic answering messages of different types that match the respective codecs, and can store automatic answering messages in an encoding form having a small amount of data. The automatic answering method includes performing a call set-up when a call signal is received through an antenna, determining if the automatic answering function is set, reading a pre-stored automatic answering message if the automatic answering function is set, selecting an encoder of a codec which corresponds to a coding type of the call signal received through the antenna during the call set-up, and encoding the read automatic answering message through the encoder.

8. A mobile communication terminal which has an automatic answering function and is provided with a plurality of different audio codecs, comprising:
-
a storage unit in which an automatic answering message for the automatic answering function is pre-stored; and
a control unit for reading the automatic answering message stored in the storage unit, and encoding the read automatic answering message through an audio codec which corresponds to a coding type of a received call, if the automatic answering function is set when the call signal is received. - View Dependent Claims (9, 10, 11, 12, 13)

14. A message storing method of a mobile communication terminal which has an automatic answering function and is provided with a plurality of different audio codecs, the method comprising the steps of:
-
receiving an audio codec selection command transmitted through a base transceiver subsystem when a call signal is received through an antenna;
performing the automatic answering function if the automatic answering function is set when the call signal is received;
reading a pre-stored automatic answering message if the automatic answering function is set;
decoding a received message by a decoder of the corresponding codec on the basis of the audio codec selection command if an audio recording is selected;
selecting an encoder of the codec which has a high compression ratio among the plurality of audio codecs, and encoding the decoded automatic answering message through the selected encoder of the codec; and
storing the encoded message. - View Dependent Claims (15, 16, 17)
