Mobile communication device for receiving alarm warnings and a method thereof

A mobile communication device for receiving alarm warnings, comprising:

• a memory module, for storing a district-warning radio frequency contrast table, wherein the district-warning radio frequency contrast table records a relationship between a plurality of districts and a plurality of warning radio frequencies for broadcasting the audio warning messages corresponding to one of the plurality of districts;
• a positioning module, generating a position data indicating a user location;
• a signal processing module, coupled to the memory module, for finding a current warning radio frequency according to a current district, wherein the current district is one of the plurality of districts in which the user is located and determined by the position data, and the current warning radio frequency is one of the plurality warning radio frequencies corresponding to the current district in the district-warning radio frequency contrast table, and wherein the current district and current warning radio frequency are automatically adjusted when the user moves from district to district amongst the plurality of districts according to new position data;
• and
• a radio receiver module, coupled to the signal processing module, for receiving a radio signal according to the current warning radio frequency and demodulating the radio signal to obtain a current audio warning message corresponding to the current district.

• a data input module, for receiving a user location data manually input by the user;
• a signal processing module, coupled to the memory module, for finding a current warning radio frequency according to a current district, wherein the current district is one of the plurality of districts in which the user is located and determined by the location data, and the current warning radio frequency is one of the plurality warning radio frequencies corresponding to the current district in the district-warning radio frequency contrast table, and wherein the current district and current warning radio frequency are automatically adjusted when the user moves from district to district amongst the plurality of districts and enters new location data;
• and
• a radio receiver module, coupled to the signal processing module, for receiving a radio signal according to the current warning radio frequency and demodulating the radio signal to obtain a current audio warning message corresponding to the current district.
