Patent number: 8242902Abstract: Disclosed is an urgent message transmission system. In the system, when a disaster warning message is received from a network provider, an originating terminal transmits the received disaster warning message to a preset urgent message recipient according to a user's request. Further, a terminating terminal having received an urgent message from the originating terminal transmits the received urgent message to a preset urgent message recipient according to a user's request. Accordingly, when an urgent message is received from a provider or a specific user, it is possible to quickly transfer the contents of the received urgent message to other users without recreating a separate urgent message.Type: GrantFiled: October 19, 2005Date of Patent: August 14, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Kyung Oh, Ki-Tae Jang, Hyuk-Min Kwon, Dong-Hoon Kim
