Abstract: An SeNB (30) informs an MeNB (20) that it can configure bearers for the given UE (10). At this time, the MeNB (20) manages the DRB status, and then sends a key S-KeNB to the SeNB (30). The MeNB (20) also sends a KSI for the S-KeNB to both of the UE (10) and the SeNB (30). After this procedure, the MeNB (20) informs an EPC (MME (40) and S-GW (50)) about the new bearer configured at the SeNB (30), 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 (40) or S-GW (50)) performs verification that: 1) whether the request is coming from authenticated source (MeNB); and 2) whether the SeNB (30) is a valid eNB to which the traffic can be offload.

Abstract: The present disclosure provides an internal cooling/external cooling-switching milling minimum-quantity-lubrication intelligent nozzle system and method, relating to the field of milling lubrication. The system includes: a vision system, configured to acquire a real-time milling depth of a workpiece and send the real-time milling depth to a lubrication manner controller for processing; a lubrication system, including an internal cooling system and an external cooling system connected together to a cutting fluid supply source through a reversing device; and the lubrication manner controller, configured to communicate with the vision system and the lubrication system respectively, and control the reversing device to act according to a set milling depth threshold and data acquired by the vision system, so as to adjust and switch to the internal cooling system or the external cooling system to work.

Abstract: An intelligent switching system for switching internal cooling and external cooling and a method are provided. The system includes a vision system, a cooling system and a control system. The vision system monitors a real-time milling state of a cutter, collects a real-time milling depth image that the cutter mills a workpiece, and transmits the collected real-time milling depth image to the control system. The control system includes a lubrication mode control center, and a motor control center. The lubrication mode control center receives the real-time image transmitted by the image collection control center; analyzes and processes the real-time image to obtain real-time milling depth data of the cutter. The motor control center receives a signal sent by the lubrication mode control center; analyzes and processes the signal, and transmits a control instruction to the cooling system. The cooling system executes a switching command issued by the control system.

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).

Abstract: A network node (21), which is placed within a core network, stores a list of network elements (24) capable of forwarding a trigger message to a MTC device (10). The network node (21) receives the trigger message from a transmission source (30, 40) placed outside the core network, and then selects, based on the list, one of the network elements to forward the trigger message to the MTC device (10). The MTC device (10) validates the received trigger message, and then transmits, when the trigger message is not validated, to the network node (21) a reject message indicating that the trigger message is not accepted by the MTC device (10). Upon receiving the reject message, the network node (21) forwards the trigger message through a different one of the network elements, or forwards the reject message to transmission source (30, 40) to send the trigger message through user plane.

Abstract: There is provided a new IWF SMC procedure for establishing security association between an MTC UE (10) and an MTC-IWF (20). The MTC-IWF (20) sends to the UE (10) at least an algorithm identifier which instructs the UE (10) to select one of algorithms for deriving a root key (K_iwf). The UE (10) derives the root key (K_iwf) in accordance with the selected algorithm, and derives at least a subkey for checking the integrity of messages transferred between the UE (10) and the MTC-IWF (20) by using the derived root key (K_iwf). The UE (10) protects uplink messages transmitted to the MTC-IWF (20) with the derived subkey. The MTC-IWF (20) protects downlink messages transmitted to the UE (10) with the same subkey derived at a core network.
