Abstract:
1. Network configuration capable of routing packet flows, comprising: a cellular base station, having at least one radio transmitter, radio receiver, and logic control management, configured to provide wireless communication for a plurality of user equipments (“UEs”); a packet data network (“PDN”) able to route packets to and from the cellular base station; a backhaul containing a routing controller and configured to logically situated between the PDN and the cellular base station, the routing controller configured to manage a plurality of routers including at least one edge router via OpenFlow protocol and operable to establish a routing path between the cellular base station and the PDN via a portion of the plurality of routers in accordance with information from an authenticating server and a charging system; and a target evolved Node B (“eNB”) boundary switch configured to have a direct link to a target eNB and configured to be logically situated at boundary of the backhaul responsible to communicate with the target eNB, wherein the routing controller forwards OpenFlow switching rules to the target eNB for setting up a new routing path to one or more interior switches in the backhaul network between the target eNB and a boundary router.
