Abstract
A network architecture for small, low-cost, high functionality portable wireless devices which shifts many of the functions performed in typical handheld communication devices to a central Application Server (AS) computer. Communication between the AS and the portable devices is performed using standard Internet Protocol (IP) packets. The AS includes a Client Proxy Server (CPS) which interfaces to applications on the server, and Device Personality Objects (DPOs) that handle the special characteristics of each different types of portable devices. Each portable device has a unique CPS/DPO pair running on the AS that accepts input from the portable devices and provides input to the various applications on the AS and which accepts outputs from the various applications and passes it to the portable devices. Communication from the portable devices to the AS is entirely via IP packets.
