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.

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.

Abstract: The invention provides for a method of selecting a Dedicated Core Network (DCN) based on assisting indication by mobile terminals, and including the step of configuring the RAN Nodes of the mobile network with the DCN Types of the serving EPC Nodes so that the RAN Nodes can map the DCN selection assisting information from the connecting mobile terminals with the right dedicated EPC Node. This allows for the RAN Node to connect the mobile terminals with EPC Node of the mobile terminal's dedication at initial attach and then keep the mobile terminals on the same DCN. Thus, a re-routing of mobile terminals NAS message from one EPC Node to another EPC node is avoided. The invention also allows for a flexible and dynamic change of the EPC Nodes dedication based on operator's configuration and policy. Additionally, the invention allows for DCN access restriction control by broadcasting of the supported DCN Types by the RAN Node.
