A communication connection is established with an information sending terminal. A short message sent from the information sending terminal is received. The short message is displayed on a display page. The short message is analyzed to identify whether a contact information field is in the short message by using a contact information determination condition. The contact information field is extracted from the short message when an identification result shows that the contact information field is in the short message. A box is displayed on the display page on which the short message is displayed to prompt a user to make a selection from function items to process the contact information field. The address book of the terminal device is updated by using the contact information field based on a function item selected by the user.
