Patent number: 9276863Abstract: Various exemplary embodiments relate to a method performed by a policy manager network node in a network, the method including: receiving accounting threshold information relating to an access session associated with an access node; receiving accounting network usage measurement message relating to the access session; determining that a total network usage of the access session exceeds a threshold; and sending a change of authorization message to the access node, wherein the change of authorization message limits a first type of network access, redirects a user of the access node, and allows a second type of network access to continue.Type: GrantFiled: June 28, 2013Date of Patent: March 1, 2016Assignee: Alcatel LucentInventors: Tiru K. Sheth, Ivaylo Tanouchev

Radius gateway on policy charging and rules function (PCRF) for wireline/wireless converged solution
Patent number: 8498286Abstract: A method and apparatus are provided for allowing a single platform to recognize and process both Diameter messages and Radius messages. A gateway is provided for translating Radius messages received from a wireline device into NASReq messages. A Diameter Proxy Agent receives both Diameter messages from a wireless device and the NASReq messages from the gateway. The Diameter Proxy Agent selects a PCRF to which to pass a NASReq message, and upon receipt of a NASReq message the PCRF either creates or updates a NASReq session object. By recognizing and processing Radius messages, wireline services can be offered at the same time as wireless services without requiring the use of a second platform. In addition, use of the PCRF server to support wireline services offers much better scalability than that offered by traditional AAA servers.Type: GrantFiled: January 10, 2011Date of Patent: July 30, 2013Assignee: Alcatel LucentInventors: Fan Mo, Satvinder Bawa, Lui Yeung, Justin Newcomb, Lay Been Tan, Felix Landry, Ivaylo Tanouchev -
