Abstract: A method for automatically saving an unknown number in a mobile phone includes comparing a telephone number being answered or dialed with numbers in an address book, and determines whether the telephone number is an unknown number. If yes, conversation content is monitored, and keywords of the conversation content are extracted after the call is successfully connected. After the call ends, a user is prompted whether to save, if yes, the keywords are arranged in order for the user to select.
