  • APPARATUS, SYSTEM AND METHOD FOR MOBILE COMMUNICATION
    Publication number: 20210029523
    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.

  • Apparatus, system and method for dual connectivity
    Patent number: 10856197
    Abstract: An SeNB informs an MeNB that it can configure bearers for the given UE. At this time, the MeNB manages the DRB status, and then sends a key S-KeNB to the SeNB. The MeNB also sends a KSI for the S-KeNB to both of the UE and the SeNB. After this procedure, the MeNB informs an EPC (MME and S-GW) about the new bearer configured at the SeNB, such that the S-GW 50 can start offloading the bearer(s) to the SeNB 30. Prior to the offloading, the EPC network entity (MME or S-GW) performs verification that: 1) whether the request is coming from authenticated source (MeNB); and 2) whether the SeNB is a valid eNB to which the traffic can be offload.

  • APPARATUS, SYSTEM AND METHOD FOR MTC
    Publication number: 20200374361
    Abstract: In order for efficiently managing communications between a UE (10) and multiple SCSs (20_1-20_n), the UE (10) includes, in one message, multiple pieces of data to be transmitted to the SCSs (20_1-20_n), and sends the message to an MTC-IWF (30). The MTC-IWF (30) receives the message from the UE (10), and distributes the date to the SCSs (20_1-20_n). Each of the SCSs sends (20_1-20_n), to the MTC-IWF (30), data to be transmitted to the UE (10) and an indicator that indicates for the SCSs (20_1-20 n) the time tolerance until the data is transmitted to the UE (10). The MTC-IWF (30) receives the data and the indicators from the SCSs (20_1-20_n), and determines when to forward the data to the UE (10) based on the indicators.

  • APPARATUS, SYSTEM AND METHOD FOR SECURITY MANAGEMENT
    Publication number: 20200367116
    Abstract: There is provided a network system including one or more first MMEs (30), and a second MME (40) separated from the first MMEs (30). In one of operation cases, the first MME (30) pushes, to the second MME (40), security context for a UE (10) that attaches to the first MME (30). The second MME (40) stores the security context. The first MME (30) further pushes the latest security context to the second MME (40), during a switch-off procedure for the first MME (30). The second MME (40) updates the stored security context with the latest security context. The first MME (30) pulls the security context from the second MME (40), when the UE (10) re-attaches to the first MME (30) or is handovered from different one of the first MMEs (30).
