Patent number: 11659359Abstract: A network node (21), which is placed within a core network, receives a message from a transmission source (30) placed outside the core network. The message includes an indicator indicating whether or not the message is addressed to a group of one or more MTC devices attached to the core network. The network node (21) determines to authorize the transmission source (30), when the indicator indicates that the message is addressed to the group. Further, the message includes an ID for identifying whether or not the message is addressed to the group. The MTC device determines to discard the message, when the ID does not coincide with an ID allocated for the MTC device itself. Furthermore, the MTC device communicates with the transmission source (30) by use of a pair of group keys shared therewith.Type: GrantFiled: November 23, 2020Date of Patent: May 23, 2023Assignee: NEC CORPORATIONInventors: Xiaowei Zhang, Anand Raghawa Prasad

Patent number: 11601790Abstract: In order for making MTC more efficient and/or secure, a base station forming a communication system connects a UE to a core network. A node serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE. The node establishes, as a connection to the base station, a first connection for directly transceiving messages between the node and the base station. Alternatively, the node establishes a second connection for transparently transceiving the messages through a different node that is placed within the core network and has established a different secure connection to the base station.Type: GrantFiled: October 9, 2020Date of Patent: March 7, 2023Assignee: NEC CORPORATIONInventors: Xiaowei Zhang, Anand Raghawa Prasad, Andreas Kunz, Genadi Velev, Toshiyuki Tamura
