Abstract: The present disclosure relates to a method and an apparatus for managing a PDN connection by inducing, by a node, a terminal to autonomously recover a failure situation or detecting the corresponding terminal when the terminal is not capable of generating or maintaining the PDN connection in a wireless communication system and the method of the present disclosure includes: detecting, by a node, a terminal in which a failure occurs in a PDN connection; and transmitting a detach request message to the terminal in which the failure occurs.

Abstract: A paging message processing method is capable of handling paging message processing delay in handover from a Wideband Code Division Multiple Access (WCDMA) network to a Long Term Evolution (LTE) network. A Mobile Switching Center (MSC) includes determines, when an inbound call occurs, whether a Mobility Management Entity (MME) system exists; transmits, when no MME exists, a paging message over an IU interface; determines, when no response message is received, whether a location registration request is received form the MME; transmits, when the location registration request is received, a location registration response to the MME system to deliver the paging message via the MME system; and processes, when a paging response is received, the inbound call. In a heterogeneous network handover from a WCDMA network to an LTE network, the MSC hands over the paging procedure control to the MME immediately so as to facilitate processing the inbound call.

Abstract: The present disclosure provides a short message service (SMS) in a mobile communication system, to thus guarantee continuity of the SMS service. According to an embodiment of the present disclosure, an operating method of a control node for providing a message service in a mobile communication system includes receiving a message from a user equipment (UE) or a message delivery center, determining an active or inactive state of the message service using a first interface, and if the message service using the first interface is disabled, transmitting detach request information for re-attach of the UE to the UE.
