Patent number: 8195187Abstract: In a radio access network, multiple radio network controllers are connected to several radio nodes using a network. The interconnected radio network controllers and radio nodes are addressable, and, therefore, each radio network controller can communicate directly with each radio node and visa versa. The radio access network can be configured to avoid active handoffs between radio network controllers by maintaining a traffic channel set up between an access terminal and a radio network controller even as the flow.Type: GrantFiled: January 18, 2005Date of Patent: June 5, 2012Assignee: Airvana Network Solutions, Inc.Inventors: Vedat Eyuboglu, Arthur J.

Patent number: 8160020Abstract: In connection with a mobile wireless subnetwork having multiple radio network controllers and multiple radio nodes, a session established for an access terminal is associated with a serving radio network controller. The association is maintained as the access terminal moves from the coverage area of one radio node to the coverage area of another radio node within the same subnetwork. Access channel packets are routed from an access terminal having an existing session to the serving radio network controller by determining the IP address of the serving radio network controller using a session identifier.Type: GrantFiled: June 25, 2001Date of Patent: April 17, 2012Assignee: Airvana Network Solutions, Inc.Inventors: M.
