Establishing a route with a level of quality of service in a mobile network
First Claim
1. A method for establishing a session in a mobile network comprising:
- finding a route;
determining the availability of resources along the route;
distributing active per-hop behaviors to ports along the route;
distributing inactive per-hop behaviors to ports near the route; and
transporting data on the route in accordance with the active per-hop behaviors.

Abstract
A session for a mobile station is established by finding a route and determining the availability of resources on the route. Thereafter, active per-hop behaviors (PHB'"'"'s) are distributed to ports along the route while inactive PHB'"'"'s are distributed to ports near the route. The active and inactive PHB'"'"'s provide information on how to route, transport, and process packets belonging to a session. In one embodiment, each of the PHB'"'"'s indicates a priority level, forwarding port number, rules for discarding packets, rules for sending packets, etc. The packets are transported from one port to another in accordance with the active PHB'"'"'s, thereby guaranteeing a level of quality of service (QoS). When the mobile station moves to a new location and changes the route, inactive PHB'"'"'s are activated on the new route. This not only allows mobile stations to communicate at a certain level of QoS even after a move, but also minimizes the delay resulting from the move.
