The present disclosure relates to a method of a mobile management entity for providing SMS services for a packet switching-only subscription in an LTE mobile communication network. Particularly, the method may include transmitting a short message to a user equipment and transmitting, to a subscription information server, information indicating the user equipment is not reachable if the transmission of the short message fails.

Method and apparatus for providing short message services for packet switching-only subscription in mobile communications network

A method for controlling access to a machine-type communication (MTC) device having a dual priority application in a mobile communication network. More particularly, a signaling method executed in a terminal configured to perform non-access stratum (NAS) signaling including low access priority indication in a mobile communication network and configured such that the low access priority is negligible. The signaling method may include performing one of a procedure of mobility management and a session management including the low access priority, receiving a back-off timer due to one of mobility management congestion control and session management congestion control and operating the back-off timer, and performing one of the mobility management procedure and the session management procedure without including the low access priority.

An idler device of the magnetic recording/reproducing apparatus is disclosed having the construction that an idler arm is inserted to the side of a clutch shaft which is installed at a lower surface of a main chassis. Without an extra construction for the assembly, a snap engagement is possibly made, so that a workability of an assembly working is improved and the number of parts can be reduced, and thus, a production cost can be reduced. In addition, the assembly of an idler gear is completed as a plate spring is fixed to an idler shaft in a state that the idler gear is inserted in the idler shaft of an idler arm. Thus, the assembly working is relatively facilitated, and a production cost can be reduced with the simple construction. Moreover, since the plate spring is installed in a state of being fixed at the protrusion bar by the stopper, the relative position of the plate spring is precisely set with respect to the neighboring parts, so that an operation reliability can be remarkably improved.
