Patent number: 8509787Abstract: A communication station, such as a base station or access point, has multiple backhaul options and distributes backhaul data between the available backhaul options. The communication station includes a transceiver for transmitting and receiving data with user equipments, multiple backhaul interface modules, and a backhaul distribution module arranged for monitoring demand for backhaul bandwidth and distributing data over the backhauls based on the demand for backhaul bandwidth. Additional modules for user data and control plane processing may be included with the user/control distinction used in distributing data over the backhauls. The backhaul options may include a preferred backhaul and an alternate backhaul.

Publication number: 20130165084Abstract: Systems and methods provide communications between applications in terminal nodes and applications agents in access nodes. The APP-agent cooperative communications can be used to improve quality of experience for users or the terminal nodes. An access node may, for example, have a parameterized scheduling system that incorporates information from the APP-agent cooperative communications in determining scheduling parameters. An application at a terminal node may, for example, modify requests for communication based on information about communication capabilities received from an access node. For APP-agent cooperative communications for multiple applications, an access node may include a master application agent to facilitate and coordinate communications to specific application agents that address APP-agent cooperative communications for specific applications. Similarly, a terminal node may use a master application and specific applications for APP-agent cooperative communications.Type: ApplicationFiled: January 17, 2013Publication date: June 27, 2013Applicant: CYGNUS BROADBAND, INC.Inventor: CYGNUS BROADBAND, INC.
