Abstract

The invention provides a method and system for adaptive point-to-point communication between a wireless communication system and a non-wireless backhaul communication system. The wireless physical layer and the wireless media-access-control layer collectively include a set of parameters, which are adaptively modified by base station controllers in multiple cells of the wireless communication system for intercommunication among those multiple cells. The IP layer and QoS parameters for communication between a selected base station controller and the non-wireless backhaul communication system collectively include a second set of parameters, which are adaptively modified for intercommunication between that selected base station controller and the non-wireless backhaul communication system. The combination of wireless communication and non-wireless communication over the entire channel includes adaptive modification of parameters for the IP layer and QoS to optimize backhaul communication between customer premises equipment and the backhaul network.
