Patent number: 10932174Abstract: 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: GrantFiled: December 20, 2016Date of Patent: February 23, 2021Assignee: NEC CorporationInventors: Francesca Serravalle, Robert Paterson, Robert Tietz

Publication number: 20200015196Abstract: A communication system is disclosed in which an anchor base station configures a RAN based paging area for a communication device. When the anchor base station determines that it is necessary to update the RAN based paging area, it seeks to inform the communication device indicating that the RAN paging area for the communication device needs to be updated at the communication device, and subsequently, the base station may broadcast system information comprising information identifying a change to the paging area (e.g. a removal of a cell). The broadcasting of system information may also be carried out in other cells of the paging area.Type: ApplicationFiled: January 29, 2018Publication date: January 9, 2020Applicant: NEC CorporationInventors: Sivapathalingham SIVAVAKEESAR, Robert TIETZ, Jonathan LEWIS

Patent number: 9788262Abstract: A communication node provides information relating to a location of a user device in a communication system. The communication node associates with a relay node for providing the user device with access to the communication system via a cell operated by the relay node. The communication node obtains an indication of whether or not the cell is configured as a mobile cell and provides, when the cell is configured as a mobile cell, information indicating that the cell is configured as a mobile cell to a further communication node.Type: GrantFiled: June 27, 2013Date of Patent: October 10, 2017Assignee: NEC CORPORATIONInventors: Robert Tietz, Kenji Kawaguchi

Patent number: 9763146Abstract: A system is disclosed in which a base station initiates a handover of a mobile relay node associated with the base station. The base station obtains information that identifies at least one further base station, and that indicates that the at least one further base station is capable of providing donor services to the mobile relay node. When the base station determines that the mobile relay node requires handover, it selects, from at least one cell of the at least one further base station identified by the obtained information, a target cell for handover of the mobile relay node, and performs handover of the mobile relay node to the selected target cell.Type: GrantFiled: June 27, 2013Date of Patent: September 12, 2017Assignee: NEC CORPORATIONInventors: Robert Tietz, Robert Paterson, Jonathan Lewis, Vivek Sharma
