Patent number: 8949927Abstract: There is described a method and apparatus for managing security for a connection between a user device and a communications network comprising at least one base station and a core network. In one embodiment, the method includes receiving at the core network security capability information for the user device connecting to the communications network. Security capability information for the base station is then obtained from memory or from the base station itself. The security capability information for the user device and the security capability information for the base station is then processed in the core network to select a security policy for a connection between the user device and the base station and the selected security policy is transmitted to the base station.Type: GrantFiled: October 27, 2008Date of Patent: February 3, 2015Assignee: Lenovo Innovations Limited (Hong Kong)Inventors: Robert Arnott, Francesca Serravalle, Jagdeep Singh Ahluwalia

Patent number: 8588745Abstract: A cellular communications system is provided in which a user device sends a Service Request to a Mobility Management Entity together with parameter data that depends on the service that is requested. The Mobility Management Entity then determines from the parameter value if AS security is required to provide the requested service. If it is not, then the Mobility Management Entity accepts the Request without providing security parameters for establishing another signalling radio bearer so that an existing signalling radio bearer is used to provide the requested service. If it is, then the Mobility Management Entity accepts the Request and provides security parameters for establishing another signalling radio bearer to be used in providing the requested service.Type: GrantFiled: August 4, 2009Date of Patent: November 19, 2013Assignee: NEC CorporationInventors: Neeraj Gupta, Jagdeep Singh Ahluwalia, Francesca Serravalle

Publication number: 20130137438Abstract: A relay communications system is described in which a base station receives a request from an MME that an overload procedure be started or stopped. The base station inserts the identity of the MME into the request and forwards the modified request to a relay node. The relay node then initiates or terminates the overload procedure in accordance with the request for mobile telephones which the MME that made the request serves, but not for mobile telephones which the MME does not serve.Type: ApplicationFiled: August 12, 2011Publication date: May 30, 2013Inventors: Francesca Serravalle, Robert Paterson, Robert Tietz
