Patent number: 9998460Abstract: A technique redirects a Diameter client command from a first server that has become unavailable to a second server consistent with a Diameter protocol. A method includes identifying a first authentication server as unavailable based on a redirect indication received from a second authentication server via a routing agent in response to a request for authentication of a user to the first authentication server. The method includes authenticating the user by the second authentication server in response to a subsequent request for authentication of the user to the second authentication server. The subsequent request for authentication includes an indication of a failure of the first authentication server. The method may include establishing a first service session in response to authenticating the user by the first authentication server and maintaining the first service session using the IP address of the first service session while the second authentication server authenticates the user.Type: GrantFiled: June 29, 2015Date of Patent: June 12, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Bhuvan Modi, Amjad Sandouka, Arun K.

Patent number: 8874109Abstract: A method and system automatically activates a mobile station in a wireless communications network. The system includes an over the air activation function (OTAF) processor in the network that initiates an activation process in response to receiving a registration message from a mobile switching center serving the mobile station requesting the activation. Each mobile station has a unit of information stored into it at the time of its manufacture to enable it to request over the air activation. That unit of information is either the network routing address of the OTAF processor, or alternately, it is a value that is translatable into that address, either an OTAF ID number that is the same value for every mobile station or it is a sequentially serialized dummy value for the mobile identification number (a dummy MIN).Type: GrantFiled: August 19, 2013Date of Patent: October 28, 2014Assignee: AT&T Mobility II LLCInventors: Arun K. Chatterjee, Brian Kevin Daly, David William James Holmes, Ileana A. Leuca
