Abstract
In a mobile communication terminal, a network access system and a method thereof using the same capable of controlling an UPnP device and connecting it to an external network, by including an UPnP control point application and a network conversion function for converting an IP address authenticated in a home network into an IP address of an external network in an OS of a mobile communication terminal, a user can easily control UPnP devices even in moving and connect them to an external network through the Internet without using an additional Internet access equipment. In addition, by using a Korean, English, number and special character input function and a voice recognition function of a mobile communication terminal, the user can control the UPnP devices efficiently.
