A method of displaying human contact data for a first mobile terminal, comprising the steps of: creating human contact data corresponding to a human contact event, when the human contact event is generated, wherein the human contact event is an event generated by a second mobile terminal that is related to a person; and displaying a name tag in a standby screen corresponding to the created human contact data, wherein the name tag is displayed differently according to a human contact frequency of the corresponding human contact event, wherein the human contact frequency is the number of human contact events generated by the second mobile terminal, wherein creating human contact data comprises: creating the name tag by analyzing log data corresponding to the human contact event; calculating at least one group level from the log data according to the human contact frequency of the corresponding human contact event by subtracting the lowest human contact frequency from the highest human contact frequency on the log data, and dividing the difference by a predetermined number of group levels; and classifying the name tag by the corresponding calculated group level, and wherein displaying the name tag differently comprises displaying characters of the name tag in a display manner corresponding to the calculated group level of the name tag, different from name tags corresponding to other group levels. creating human contact data corresponding to a human contact event, when the human contact event is generated, wherein the human contact event is an event generated by a second mobile terminal that is related to a person; and displaying a name tag in a standby screen corresponding to the created human contact data, wherein the name tag is displayed differently according to a human contact frequency of the corresponding human contact event, wherein the human contact frequency is the number of human contact events generated by the second mobile terminal, wherein creating human contact data comprises: creating the name tag by analyzing log data corresponding to the human contact event; calculating at least one group level from the log data according to the human contact frequency of the corresponding human contact event by subtracting the lowest human contact frequency from the highest human contact frequency on the log data, and dividing the difference by a predetermined number of group levels; and classifying the name tag by the corresponding calculated group level, and wherein displaying the name tag differently comprises displaying characters of the name tag in a display manner corresponding to the calculated group level of the name tag, different from name tags corresponding to other group levels. creating the name tag by analyzing log data corresponding to the human contact event; calculating at least one group level from the log data according to the human contact frequency of the corresponding human contact event by subtracting the lowest human contact frequency from the highest human contact frequency on the log data, and dividing the difference by a predetermined number of group levels; and classifying the name tag by the corresponding calculated group level, and wherein displaying the name tag differently comprises displaying characters of the name tag in a display manner corresponding to the calculated group level of the name tag, different from name tags corresponding to other group levels.
