Patent number: 10602416Abstract: Technology providing seamless mobility to mobile processing devices in an Information Centric Network (ICN) is provided. A first point of attachment (PoA) is configured to communicate with a first processing device identified by a device ID and receive content objects addressed to the first processing device. The first PoA is further configured to determine that the first processing device is no longer communicating with the first PoA and moving to a second PoA, and generate a forwarding label identifying the second PoA and the device ID. The first PoA is further configured to append the forwarding label to any content object addressed to the first processing device and not forwarded by the first PoA to the first processing device before it moves, and forward each such content object to the second PoA.Type: GrantFiled: July 13, 2017Date of Patent: March 24, 2020Assignee: Futurewei Technologies, Inc.Inventors: Ravishankar Ravindran, Asit Chakraborti, Aytac Azgin

Patent number: 10595222Abstract: A method performed by a user equipment (UE) for enabling cross-layer receiver oriented dynamic multicast in cellular access. The method includes receiving an information-centric networking content-identifier (ICN-CID) from an application. The method generates a content medium access control identifier (CMAC-ID) using the ICN-CID. The CMAC-ID maps the ICN-CID to a medium access control (MAC) layer.Type: GrantFiled: July 5, 2018Date of Patent: March 17, 2020Assignee: Futurewei Technologies, Inc.Inventors: Ravishankar Ravindran, Aytac Azgin, Syed Obaid Amin, Asit Chakraborti
