First Claim
1. A routing method for routing data packets from a source terminal (MN1, H1;
- Enx, Ex) to a destination terminal (MN2, H2;
MN1, H1) via at least one communication network (NW1;
NW1, NW2), said at least one communication network comprising at least one mobility agent entity (HA1, HA2, AR1, AR2, ERn, ERm)) for each of said terminals, the method comprising the steps of;
establishing a route (1, 2, 3, 4;
4, 5, 6, 7) from the source (MN1, H1;
Ex, ENx) via at least one first mobility agent (AR1;
ERn) associated to said source, at least two consecutively arranged second mobility agents (HA2, AR2;
HA1, AR1) associated to said destination, to said destination (MN2, H2;
MN1, H1), deciding that said route is to be optimized, and upon said decision, rerouting said route from one of said at least one first mobility agents (AR1;
ERn) directly to one of the at least two consecutively arranged second mobility agents (AR2;
AR1) such that at least one intermediate mobility agent (HA2;
HA1) in said route is bypassed in the resulting rerouted route.

Abstract
A routing method for routing data packets from a source terminal to a destination terminal via at least one communication network, said at least one communication network comprising at least one mobility agent entity for each of said terminals, the method comprising the steps of: establishing a route from the source via at least one first mobility agent, at least two consecutively arranged second mobility agents, to said destination, deciding that said route is to be optimized, rerouting said route from one of said at least one first mobility agents directly to one of the at least two consecutively arranged second mobility agents such that at least one intermediate mobility agent in said route is bypassed in the resulting rerouted route.
