Ericsson Assigned Patent

(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., May 1 -- Ericsson, Stockholm, Sweden, has been assigned a patent (8,166,527) developed by Renhua Wen, San Ramon, Calif., Alfred C. Lindem III, Cary, N.C., and Anand K. Oswal, Sunnyvale, Calif., for an "optimized security association database management on home/foreign agent." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for security association management on a home and foreign agent are described. In one embodiment, in response to a first mobile network registration request from a mobile node, a remote authentication facility is accessed to retrieve a security association for the mobile node for authenticating and providing a first network connectivity to the mobile node, wherein the security association is associated with a lifespan. The security association is inserted in a local security association database (SADB) to create a security association entry, wherein the security association entry includes the lifespan. A second mobile network registration request from the mobile node after the first connectivity is terminated is received and the security association entry in the local SADB that corresponds to the mobile node is used to provide authentication of the mobile node without having to access the remote authentication facility again if the lifespan associated with the security association entry is valid." The patent application was filed on Nov. 16, 2007 (11/985,801).
