Abstract

Official abstract text for this publication.

A wireless intelligent switch engine (WISE) is described. The wireless intelligent switch engine provides for automatic switching between different physical wireless interfaces in mobile devices while roaming to maintain a wireless network connection. WISE functions as a bridge between a mobile device and multiple wireless network interfaces to provide automatic and seamless switching among networks while roaming. The mobile device sees WISE as a LAN interface and communicates with WISE using the TCP/IP protocol stack, thus providing a PPP-less configuration that uses the TCP/IP protocol stack regardless of the wireless interface.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for switching between network interfaces, comprising: a switch engine configured for operating at the data link layer of a protocol stack for a given interconnection model configured for operation with multiple network interfaces; said switch engine configured to automatically select, based on a priority criterion communicated at the data link layer, and establish a network connection session for a mobile device through an active interface, wi…
