Communication terminal equipment

A communication terminal comprising:

• a transmitting/receiving module configured to transmit and receive communication signals including voice communication information and data communication information;
• a pattern memory which stores a plurality of stored data patterns that correspond to various kinds of emergency information;
• an ID memory configured to store a transmission source ID corresponding to the plurality of stored data patterns stored in the pattern memory;
• a pattern identifier configured to determine whether a pattern that is contained in data communication information received by the transmitting/receiving module matches one of the plurality of stored data patterns stored in the pattern memory while the transmitting/receiving module is receiving voice communication information;
• an ID identifier configured to determine whether a transmission source ID in the data communication information matches the transmission source ID in the ID memory corresponding to said one of the stored data patterns when the pattern in the data communication information matches said one of the stored data patterns and
• a notification unit configured to selectively notify a user of a receipt of emergency information when the pattern contained in the data communication information matches said one of the stored data patterns and when the transmission source ID in the data communication information matches the transmission source ID stored in the ID memory corresponding to said one of the stored data patterns.
