US Patent 8681735 Wireless communications system for controlling communication path

A controller manages a connection of a wireless terminal to a wireless base station, and provides a source base station with information for connecting the wireless terminal by way of an anchor when the wireless terminal moves between wireless base stations. When devices on both sides of an anchor connected communication are wireless terminals connected to wireless base stations in said same wireless communications system, a wireless base station device switches a path such that data is transmitted/received between the wireless base stations to which the wireless terminals are connected on both sides of the anchor connected communication without intervention of the anchor.
