Patent number: 9271197Abstract: An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.Type: GrantFiled: May 21, 2014Date of Patent: February 23, 2016Assignee: Futurewei Technologies, Inc.Inventors: John Kaippallimalil, Hinghung Anthony Chan, Zhixian Xiang, Khosrow Tony Saboorian, Serge Manning

Patent number: 8621198Abstract: Methods and system for simplified Protocol for Carrying Authentication for Network Access (sPANA) are disclosed. In the broadband architecture such as Broadband forum or WiMAX forum, a Network Access server (NAS) is one IP hop away from a user. Therefore, it is possible to relax the need in PANA to obtain an IP address prior to authentication. A PANA client (PaC) may use an unspecified IP address (e.g. 0.0.0.0 in TPv4) as a source address for authentication. A PANA Authentication Agent (PAA) may use an IP broadcast address as a network layer destination address (e.g. 0xffffffff). The present invention defines PANA Attribute-Value Pairs (AVPs) and procedures that allow a Challenge-Handshake Authentication Protocol (CHAP) exchange to occur in PANA. The PANA CHAP support may facilitate smooth migration from Point-to-Point Protocol (PPP) sessions to IP sessions in a DSL Broadband network environment. The sPANA can be desirably compatible with the PANA.Type: GrantFiled: August 28, 2008Date of Patent: December 31, 2013Assignee: FutureWei Technologies, Inc.Inventors: Yangsong Xia, John Kaippallimalil
