  • Patent number: 11134103
    Abstract: A mobile network system comprises a security device and a network device. The security device stores slice security requirements which are different for each slice ID (identification). The slice ID indicates a network slice in a core network. The network device transmits, to the security device, a Slice Security Request including the slice ID. The network device receives, from the security device, a Slice Security Response including the slice security requirements related to the slice ID. The network device selects, based on the slice security requirements, a security algorithm for the network slice.

  • Publication number: 20210204119
    Abstract: Apparatuses, methods, and systems are disclosed for key refresh triggering. One apparatus includes a transceiver and a processor that starts a counter corresponding to a UE having a small-data traffic pattern. In response to the transceiver receiving small-data traffic associated with the UE, the processor determines if a security key is valid based on a value of the counter. If the value of the counter indicates the security key is invalid, then the processor triggers a key refresh procedure. The processor relays the small-data traffic in response to the UE having a valid security key.

  • Publication number: 20210152615
    Abstract: Apparatuses, methods, and systems are disclosed for selecting a network slice type for media traffic of an IMS session. One apparatus includes a processor and a transceiver that communicates with a mobile communication network (“MCN”) using multiple network connections. The processor receives a first request to establish an IMS session with an IMS network, the first request including multiple media types. Here, the IMS network is reachable via the multiple network connections, each network connection communicating with a different network slice type of the MCN. The processor selects a network connection to be used for communicating media traffic for each media type and transmits a IMS session request to the IMS network using a first network connection. Here, the IMS session request indicates parameters to be used for communicating the media traffic for each media type using the selected network connection.

  • 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.
