  • Patent number: 11729613
    Abstract: In order for supporting separate ciphering at an MeNB (20) and an SeNB (30), the MeNB (20) derives separate first and second keys (KUPenc-M, KUPenc-S) from a third key (KeNB). The first key (KUPenc-M) is used for confidentially protecting first traffic transmitted over U-Plane between the MeNB (20) and a UE (10). The first key (KUPenc-M) may be the same as current KUPenc or a new key. The second key (KUPenc-S) is used for confidentially protecting second traffic transmitted over the U-Plane between the UE (10) and the SeNB (30). The MeNB (20) sends the second key (KUPenc-S) to the SeNB (30). The UE (10) negotiates with the MeNB (20), and derives the second key (KUPenc-S) based on a result of the negotiation.

  • Patent number: 11711736
    Abstract: A UE (10) provides information on potential S?eNB(s). The information is forwarded from an MeNB (20_1) to an M?eNB (20_2) such that the M?eNB (20_2) can determine, before the handover happens, whether the M?eNB (20_2) will configure a new SeNB (S?eNB) and which S?eNB the M?eNB (20_2) will configure. In one of options, the MeNB (20_1) derives a key S?-KeNB for communication protection between the UE (10) and the S?eNB (30_1), and send the S?-KeNB to the M?eNB (20_2). In another option, the M?eNB (20_2) derives the S?-KeNB from a key KeNB* received from the MeNB (20_1). The M?eNB (20_2) sends the S?-KeNB to the S?eNB (30_1). Moreover, there are also provided several variations to perform SeNB Release, SeNB Addition, Bearer Modification and the like, in which the order and/or timing thereof can be different during the handover procedure.

  • Patent number: 11659359
    Abstract: 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.

  • Patent number: 11601790
    Abstract: 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.
