Wireless intelligent switch engine |
摘要 |
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.
