Method for route optimisation, router, and entity risk management firm location.

摘要

Embodiments of the present invention provide a route optimization method, where the method includes: establishing a forwarding tunnel between a first mobile router MR in which first user equipment UE is currently located and a second MR in which second UE is currently located, where at least one UE of the first UE and the second UE is currently located in a visited network; and transmitting data between the first UE and the second UE over the forwarding tunnel. According to the embodiments of the present invention, a forwarding tunnel is established between MRs in visited networks, so that data is transmitted over the forwarding tunnel, which can reduce route redundancy.
