SYSTEM AND METHOD FOR USE OF DUAL-TONE MULTI-FREQUENCY SIGNALS IN A WIRELESS COMMUNICATION SYSTEM

摘要

A data storage area allows a user of a wireless communication device to enter data to be processed and transmitted as a series of dual-tone multi-frequency (DTMF) tones. A wireless communication device transmits call origination over the traffic channel and can transmit DTMF tones over the traffic channel. The user may enter data (202) into a storage area along with an indication that the entered data should be processed as DTMF tones (210). Data entered as DTMF tones is processed (222) and transmitted (226) over the traffic channel as a series of DTMF tones. A data storage area may have predetermined locations wherein data stored in the predetermined locations are processed as DTMF tones. Alternatively, a data flag or other indicator may be associated with the data to indicate processing as DTMF tones.
