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: The present invention relates to a method and a device by which first user equipment (UE) that is located out of the range of a group communication service determines a relay through a proximity service (ProSe) in a wireless communication system. Particularly, the method comprises the steps of: receiving traffic transmitted by second UE which already relays group communication; determining whether the traffic is information bound to group communication; determining relay UE by using a discovery procedure for a relay for the group communication, when the traffic is not recognized as the information bound to the group communication; and determining the second UE as the relay UE for the group communication, when the traffic is recognized as the information bound to the group communication.

Abstract: One embodiment of the present specification provides a machine type communication (MTC) monitoring method to be implemented by a network node. The MTC monitoring method comprises the steps of: recognizing a drop of at least one bearer in a target base station by the control of a specific monitoring event when the monitoring event is satisfied according to a movement of an MTC device to be processed through one or a plurality of bearers toward a target base station of an invalid region through a packet data network (PDN) connected with a source base station; transferring, to the MTC device, information for indicating an entry into a valid region or information for indicating an activation of the bearers when detecting the escape of the MTC device from the invalid region and entrance into the valid region; and carrying out a procedure for resetting the dropped bearers.
