Patent number: 7107082Abstract: The present invention is related to a method of exchanging data between mobile phones through an inter-working function or proxy inter-working function service. The method includes a first step in which as a transmitting user manipulates a keypad of a transmitting mobile phone, the transmitting mobile phone enters transmission mode. At a second step, as a receiving user manipulates a keypad of a receiving mobile phone, the receiving mobile phone enters reception mode. Thereafter, the transmitting and receiving mobile phones are operated in data exchange mode for transmitting data from the transmitting mobile phone to the receiving mobile phone. Finally, data transmission from the transmitting mobile phone to the receiving mobile phone is completed.Type: GrantFiled: February 7, 2002Date of Patent: September 12, 2006Assignee: SK Teletech Co., Ltd.Inventor: Jae Young Lee
