A method and an apparatus for vehicle-to-vehicle or V2V message service are disclosed. In at least one aspect, a method of operating a V2V message service apparatus in a V2V communication system includes when a first vehicle equipped with the V2V message service apparatus enters a particular road link, subscribing the first vehicle to a V2V message server with the particular road link as a topic, and receiving an event message including an event-situated road link as a topic from the V2V message server, and determining whether to issue an alarm corresponding to the event message based on a preceding and trailing relationship between the first vehicle and a second vehicle that published the event message.

Disclosed are an apparatus and a method for voice processing in a mobile communication terminal. A plurality of microphones are used to remove environmental noise at the time of voice communication, so that it is possible to perform high-quality voice communication and video telephony. Moreover, it is possible to perform voice recording even when a user does not open a mobile communication terminal. Furthermore, when voice is recorded or sound is recorded during moving image photographing, a plurality of microphones are effectively utilized to achieve good-quality recording and to perform recording conveniently even when the folder or the slider of the mobile communication terminal is closed. Therefore, it is possible to provide improved convenience in using the mobile communication terminal.
