Patent ID: 8532597

Claim:
A mobile terminal having an alternative frequency search function, the terminal comprising: a control unit comprising: a radio data decoder for decoding radio data containing a program identifier and for differentiating the radio data by type; a radio data filter for extracting the program identifier from the radio data, for comparing the extracted program identifier with a previously stored program identifier, and for instructing to update an alternative frequency list when the extracted program identifier is substantially identical with the previously stored program identifier; and a radio data updater for updating the alternative frequency list in response to an instruction of the radio data filter; a storage unit for storing the alternative frequency list and the differentiated radio data; and a radio data comparator for counting a number of receipts of each of alternative frequencies listed in the alternative frequency list after updating the alternative frequency list, and for removing alternative frequencies of which a count value is less than an average number of receipts from the alternative frequency list.
