This paper describes the design and implementation of software architecture for Linux-based mobile terminals supporting interworking between CDMA and WiBro. The software architecture includes network switching controller which controls the network switching procedure among other modules and multi-option network selection algorithm. The software architecture also includes function which provides network transparency to the higher network layer and mobile IPv4 based mobility function. The implemented software architecture is designed to have expandability in each function and easily applied to the terminal with more than two networks. The procedures and functions of software architecture are verified by interworking with the multimedia application program.
