Abstract: Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

Abstract: One embodiment of the present specification provides a method by which a user equipment (UE) reselects a network node in charge of a control plane. The method can comprise the steps of: retransmitting, by the UE, a non-access stratum (NAS) request message if the UE transmitted the NAS request message to a network node in charge of the control plane through a base station but has not received a response message; transmitting, by the UE, an access stratum (AS) message, which includes an indication showing no response from the network node, to the base station if the retransmission of the NAS request message has repeated by a preset value or more; and reselecting another network node in charge of the control plane instead of the network node in a disabled state if information indicating that the network node is in the disabled state is received from the base station.

Abstract: Provided in one disclosure of the present specification is a method for transmitting a detection signal from user equipment (UE). The method comprises the steps of: driving a mobility management (MM) delay time timer, when the MM delay time timer is received by the UE from a mobility management entity (MME) in a network; confirming the priority for detecting at least one other UE, when detection of the at least one other UE is required before the MM delay time timer expires; and randomly selecting a resource based on a shared resource pool included in system information, which is broadcasted from a base station, and then transmitting to the at least one other UE a detection signal including a proximity service code from the randomly selected resource, when the detection of the at least one other UE is considered to have high priority or to be urgent.
