MOBILE ROUTER WITH SESSION PROXY

摘要

A mobile router having a session proxy module is disclosed. The session proxy module may act as a proxy (such as a TCP proxy) for all sessions (e.g., TCP sessions) going through the mobile router. That is, for example, when a local end-user seeks to establish a TCP session from their local end-user device (such as laptop) with a destination (such as a third party server), the session proxy module may (1) terminate the TCP session coming from the local end-user device and (2) establish a TCP (or some other protocol) session on the backhaul interface with the destination. That way, all end-user traffic between the end-user and the destination may be transparently routed through the mobile router.

主权项

1. A method of operating a mobile router disposed within a vehicle and comprising a wireless local area network interface and a wireless cellular network interface, said method comprising:
detecting an attempt by a mobile device disposed in said vehicle to establish a transport protocol session with a destination device via said wireless local area network interface; responding to said detected attempt by:
automatically initiating a first transport protocol session between said mobile router and said mobile device over said wireless local network interface; andautomatically initiating a second transport protocol session between said mobile router and said destination device over said cellular network interface, said second transport protocol session comprising a cellular network layer and a wide area network layer; monitoring said cellular network layer and said wide area network layer by sending data packets over said cellular network interface to detect if said wide area network layer or said cellular network layer is interrupted; detecting if said wide area network layer or said cellular network layer is interrupted by detecting an interruption in said second transport session; and after detecting an interruption in said second transport protocol session:
maintaining said first transport protocol session; andautomatically reestablishing said second transport protocol session while maintaining said first transport protocol session.
